DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a shoring system as a temporary device used when constructing a heavy-weight structure such as a bridge having a reinforced concrete structure.

[0002]

2. Description of the Related Art Conventionally, when constructing a structure such as a bridge having a reinforced concrete structure, the structure is supported by a shoring as a temporary device that is erected on the ground or the like until the completion of the structure. I have to.

[0003] The support in this case is determined by the scale and shape of the structure. In recent years, with the increase in the size and weight of the structure, a large and sturdy structure is often used. In this case, a crane truck or the like is used for assembling the shoring to a predetermined position and disassembling it after use.

[0004] On the other hand, this type of shoring, of course, has a shoring main body which is set in an assembling column structure, but is generally connected to a base body connected to a lower end of the shoring main body or an upper end thereof. The height adjustment body is provided.

Therefore, when assembling or dismantling a large-scale shoring of this type, not only the shoring main body but also the base body and the height adjusting body are transferred by a crane truck or the like. Compared to traditional manual assembly and disassembly work,
Work can be performed quickly and easily.

However, in the shoring method proposed so far, for example, it is assumed that the height adjusting body is formed in a rough screw jack structure, and a necessary number of the height adjusting bodies are arranged at necessary places. Therefore, it has been pointed out that there is a problem that the transfer is not only troublesome, but also that it cannot sufficiently counteract the effects of horizontal force during use, for example, an earthquake or an uneven load.

In the case of dismantling this type of shoring, it is often the case that the height adjusting body is shortened to insulate the load acting on the shoring from the completed structure above the height adjusting body. That is, the pressure is released, and the support is dismantled from this state, that is, the lower support body and the base body are transferred using a crane truck or the like.

However, in this case, the length obtained by shortening the height-adjusting body is very small. Therefore, in many cases, the shortened height-adjusting body is manually removed and a large work is required. It has been pointed out that after securing a space, the lower support body and the base body must be transferred using a crane truck or the like.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to improve the working efficiency in assembling work for use, and in particular, to disassemble in advance. In the dismantling work after use, it can be dismantled so as to avoid the constructed structure, the manual work is greatly reduced, and the dismantling work using a crane truck etc. The aim is to provide a shoring that is optimal for significantly improving the efficiency of the construction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on the illustrated embodiment. As shown in FIG. 1, a shoring according to an embodiment of the present invention comprises a shoring main body 1 and a base. It has a body 2 and a height adjusting body 3.

The shoring main body 1 constitutes a main body portion in the shoring, and in the present invention, a strut formed by appropriately combining a plurality of vertical and horizontal members and diagonal members, that is, an assembled strut structure. Is set to

In the illustrated embodiment, the support body 1 is connected to a lower support 11 in the figure, which is a so-called fixed support, and is connected in series to the upper end of the support 11 so as to be vertically connected. It has a telescopic strut body 12 at the top in the figure set to be telescopic in the direction.

The telescopic strut body 12 includes a base frame 13 set as a fixed length body, a plurality of adjusting rods 14 which protrude and retract with respect to the base frame 13, and an upper end of the plurality of adjusting rods 14. A head joint 1 that is connected and connected to the lower end of the height adjusting body 3
5, a guide frame 16 which is arranged in parallel with the adjustment rod 14 while being connected to the head joint 15 and whose lower end slides in and out of the base frame 13 in a state of sliding contact, and a guide frame 16 between the guide frame 16 and the base frame 13. And a guide frame retracting means 17 that is disposed and makes the guide frame 16 protrude and retract from the base frame 13.

The base frame 13 has a pipe 13a as a vertical member standing at four corners and a mold 13b as a horizontal member connecting the pipes 13a in the horizontal direction. The adjustment rod 14 is inserted through the upper end opening of the pipe body 13a so as to protrude and retract into the pipe body 13a.

The adjusting rod 14 is a pipe having an outer diameter slightly smaller than the inner diameter of the pipe 13a in the illustrated embodiment, and is formed at an appropriate interval (shown by a broken line in the figure) from the lower end to the upper end. It has an opened lateral hole (not shown).

The stopper 14a inserted in the horizontal hole
Is the upper end of the pipe 13a, more precisely, the pipe 13a
The length of the adjustment rod 14 protruding from the pipe body 13a by being locked to the upper end of the mold body 13b connected to the
That is, the selected length of the telescopic support 12 is maintained.

The head connection 15 is for preventing the upper ends of the plurality of adjustment rods 14 from individually tilting so that each adjustment rod 14 can be smoothly protruded and retracted from each pipe body 13a. A guide frame 16 which is connected to the head joint 15
The four corners on the lower end side are the mold 13b in the base frame 13.
The four corners formed by the above are slid in contact with the sliding contact portions 13c provided continuously, so that the backlash with the base frame 13 is prevented and the horizontal force can be countered in the same manner as a so-called oblique member.

The guide frame retracting means 17 is arranged between the guide frame 16 and the base frame 13 so that the guide frame 16 is
3, it is sufficient that the rod body 17b is protruded and retracted, and it is not necessary to be limited to a specific configuration. However, in the illustrated embodiment, the rod body 17b is appropriately connected to the cylinder body 17a. For example, the adjustment rod 14 is intermittently moved by a stroke corresponding to the interval between the horizontal holes formed in the adjustment rod 14 so that the telescopic support 12 can be intermittently expanded and contracted.

Therefore, in the telescopic strut body 12 formed as described above, the guide frame retracting means 17 is operated in a state where the stopper 14a is removed from the adjusting rod 14, so that the base frame 13 On the other hand, the guide frame 16 appears and disappears,
At this time, the adjusting rod 14 is retracted with respect to the base frame 13 in synchronization with the guide frame 16.

When the adjusting rod 14 is protruded and retracted to a predetermined length with respect to the base frame 13, the stopper 14a
Is inserted into the adjustment rod 14 through the opened horizontal hole, so that the adjustment rod 14 is kept in the state of being protruded from the base frame 13, that is, the selected length of the telescopic support 12 is maintained.

As a result, by adjusting the length of the telescopic strut 12 to an appropriate length at the time of assembling the support, it is possible to reduce the height adjustment amount of the height adjuster 3 described later to a small amount. become.

It is to be noted that the support body 11 is
States that this is a fixed support, but this means that it is not configured such that the height dimension can be adjusted like the telescopic support 12 when the support is assembled. Thus, to this extent, it is of course possible, for example, for this to be formed in a foldable structure.

The base body 2 basically maintains the upper support body 1 in a stable state during use of the support, and includes a support member 21 connected to the lower end of the support body 1,
A base member 22 arranged below the support member 21 at an appropriate interval and fixed on a fixed side such as the ground;
A seat member 23 disposed between the support member 21 and the support member 21, and running means running on the base member 22 with the upper end connected to the support member 21 while being set to have a longer dimension in the vertical direction from the seat member 23. 24 and the base member 2 while being held by the support member 21.
And a driving means 25 connected to the driving means 2 to enable the traveling means 24 to travel.

The support member 21, the base member 22, and the seat member 2
Reference numeral 3 denotes a main part of the base body 2, and H
At the time of assembling the shoring, the supporting structure is assembled into a cross-girder structure, and adjacent members are interconnected and integrated.

When the support is dismantled, the seat member 23 remains connected to the support member 21 but is separated from the base member 22 and maintained in a state held by the support member 21. .

On the other hand, the traveling means 24 and the driving means 25
Are required when disassembling the shoring. Even when the shoring is used, the equipment is not required, and is prepared as a so-called attachment.

First, the traveling means 24 supports the support member 21 from below in place of the seat member 23 when the support is dismantled, and is set so that the length thereof can be adjusted in the vertical direction by the seat member 23. The upper end is connected to the support member 21 while the lower end has a plurality of rollers (not shown) that roll on the base member 22.

The traveling means 24 is forcibly raised by a hydraulic jack (not shown) disposed between the base member 22 and the support member 21 when the support is disassembled. Is arranged in a gap having a dimension larger than the height dimension of the seat member 23 formed on the base member 22 and is connected to the support member 21 so as to be able to run on the base member 22.

By the way, the platform member 22 on which the traveling means 24 travels may be formed so as to have a necessary length in advance. However, during the use of the support, a so-called extra portion is formed. There is a possibility that the work may be obstructed and the workability using the support work may be reduced.

Therefore, as shown in the illustrated embodiment, when the traveling means 24 travels, the extension base member 22a is connected to the base member 22 so as to be separable so as to secure a required length. It would be good to do.

Next, the driving means 25 is connected to the base member 22 while being held by the support member 21 at the time of disassembly of the support, and is connected to the base member 22 of the traveling means 24 and to the base member 22 by the extension base member. 22a, the extension base member 2
2a.

Then, specifically, the driving means 25
The support member 21 is grounded so that the height can be adjusted, and the gear 25b is configured to rotate by driving a motor 25a. The gear 25b is formed on the inner bottom of a groove 22b formed in the base member 22. Rack part 2 consisting of a set tooth row
2c.

The base member 22 having the rack portion 22c
May be changed to a so-called forward feed, and the base member 22 and the extension base member 22
a at the end of the traveling means 24
It is preferable that a stopper portion 22d for forcibly preventing travel of the vehicle be provided.

The seat member 23 is, as described above,
At the time of disassembly of the support, the support member 21 is kept connected to the support member 21 and is separated and not so-called removed. Particularly, in the illustrated embodiment, the support member 21 is formed in the groove 22b formed in the base member 22. It has a guide 23a to be inserted, and functions to prevent so-called derailing and falling on the base member 22 of the traveling means 24.

Therefore, the base body 2 formed as described above
In this case, the support member 21, the seat member 23, and the base member 22 can be assembled into a double-girder structure during the assembling of the support, so that the upper support member main body 1 can be supported while being maintained in a stable state. Become.

The base member 2 is provided with support members 21 and
Since the seat member 23 and the base member 22 are assembled and integrated in a double-girder structure, they can be transferred using a crane truck or the like at the time of assembling or disassembling the support.

In the base member 2, the seat member 2
3 is disengaged from the base member 22, and the traveling means 24 is provided between the support member 21 and the base member 22 which are enlarged by the extension of a plurality of hydraulic jacks disposed between the support member 21 and the base member 22. , The lateral movement of the support member 21,
That is, it is possible to move the base member 22 in the arrangement direction.

At this time, since the driving means 25 is provided on the support member 21 while being connected to the base member 22, the traveling of the traveling means 24 by the driving of the driving means 25 is realized. In the above, the movement of the support member 21 realizes so-called overall lateral movement of the support.

As a result, when the height adjuster 3, which will be described later, is removed from the upper end of the support body 1 for dismantling the support, the height adjuster 3 is moved by the entire lateral movement of the support.
, A large space can be formed above, and the operation of transferring the height adjusting body 3 using a crane truck or the like can be easily performed.

The base member 22, in particular, the extension base member 22
Depending on the setting of the length a, the support can be relocated to a new installation location without removing the height adjusting body 3 from the upper end of the support main body 1.

The height adjusting body 3 is provided with a lower frame 31 connected to a head tie 15 forming the upper end of the support body 1 and an upper frame opposing the lower frame 31 with an appropriate space therebetween. A frame 32, and a plurality of screw jacks 3 arranged between the upper frame 32 and the lower frame 31 so as to be vertically expandable and contractible.
And a plurality of screw jacks 33 are integrally connected to the upper frame 32 and the lower frame 31 so as to be inseparable from each other. A lateral displacement prevention mechanism 34 for preventing the relative movement of the upper frame 32 and the lower frame 31 in the lateral direction is disposed between them.

The lower frame 31 is formed in a so-called frame shape so that a plurality of screw jacks 33 can be erected, and the upper frame 32 can be connected to upper ends of the plurality of screw jacks 33. As long as it is sufficient, the configuration is not limited to a special configuration.

The screw jack 33 is provided with a handle 33.
The screw rod 33b is turned into the lower socket 33c by the rotation operation of a.
The upper end of the screw rod 33b is inseparably connected to the upper socket 33d.

Note that the lower socket 33c and the upper socket 33d are inseparably connected to the lower frame 31 and the upper frame 32, respectively, so that the plurality of screw jacks 3c are formed.
3 are inseparably connected to the upper frame 32 and the lower frame 31, respectively.

On the other hand, the lateral displacement prevention mechanism 34 is
And an upper tube 34b connected to the upper frame 32. The upper tube 34 is provided in the lower tube 34a.
It is configured such that b is moved in and out in a sliding contact state.

Although not shown, the lateral displacement preventing mechanism 3
4 is set so that the upper cylinder 34b is prevented from coming out of the lower cylinder 34a.

Therefore, in the height adjusting body 3 formed as described above, the plurality of screw jacks 3
3 is connected to the lower frame 31 and the upper frame 32 and is maintained in an integrated state.
Is maintained in a state where the relative movement in the lateral direction is prevented, so that the work of suspending the height adjusting body 3 using a crane truck or the like at the time of assembling or disassembling the shoring, that is, The height adjustment body 3 can be easily transported, and when used, can sufficiently resist horizontal external force action, for example, the action of an earthquake or an uneven load.

At the time of assembling the height adjusting body 3, the extension state of the plurality of screw jacks 33 is made uniform due to the interposition of the lateral displacement prevention mechanism 34. 1, when connected to the upper end of the
It is easy to set the upper end of the screw jack to a horizontal state, that is, it is not necessary to adjust the plurality of screw jacks 33 to expand and contract to realize the horizontal state.

When the height adjuster 3 is shortened in order to disassemble the support, when the height adjuster 3 is shortened, the hydraulic pressure provided in the space formed between the lower frame 31 and the upper frame 32 is reduced. The extension of the jack (not shown) insulates the load acting on the height adjusting body 3, that is, the screw jack 33 from above, that is, allows the pressure to be released, and shortens the screw jack 33 by manual operation. Can be easily realized.

When a form F or the like for constructing a building is placed on the upper end of the height adjusting body 3 as shown in the installation diagram in the figure, a sleeper is used to prevent slippage. It is preferable to interpose an appropriate spacer S such as

In the shoring according to this embodiment formed as described above, at the time of assembling, first, the base body 2 is arranged at a predetermined position by using a crane truck or the like.
The support body 1 is connected so as to be assembled using a crane truck or the like, and the height adjustment body 3 is connected to the support body 1 so as to be assembled using a crane truck or the like.

At this time, in the base body 2, the traveling means 24, the driving means 25 and the extension base member 22a to be prepared as attachments are of course removed in advance.

In the case where the support body 1 has the telescopic strut 12, the telescopic strut 12 is set up to a predetermined length at another place and then transferred to a predetermined position using a crane truck or the like. You.

In the case where the support body 1 is formed by connecting the telescopic support 12 to the fixed support 11, the telescopic support 1 may be used.
It is a matter of course that the fixed column 11 is previously mounted on the base body 2 using a crane truck or the like before the transfer of the second support 2.

The height adjuster 3 mounted on the uppermost stage is set up to a predetermined length in advance in the same manner as the telescopic strut 12, and then transferred by a crane truck or the like. It is needless to say that the upper frame 32 can be maintained in a predetermined horizontal state by being uniformly expanded and contracted.

The height adjuster 3 connected to the upper end of the support body 1 places a formwork F or the like for building a structure with an appropriate spacer S such as a sleeper interposed at the upper end. Then, if necessary, the screw jack 33 is expanded and contracted to a small width so that the upper frame 32, that is, the upper mold F or the like is aimed at a predetermined level.

Contrary to the above, when the support is dismantled, first, the height adjusting body 3 is shortened, and the support, that is, the pressure is released from the height adjusting body 3.

At this time, if there is a gap enough to shorten the height adjusting body 3, that is, a gap enough to separate the height adjusting body 3 from the upper end of the support body 1, The adjusting body 3 may be suspended horizontally using a crane truck or the like and directly removed from the upper end of the support body 1.

At this time, since the height adjusting body 3 of the present invention is configured as an integrated structure, it is possible to perform a horizontal suspension operation using the above-described crane truck or the like. Become.

However, in many cases, even if the height adjusting body 3 is shortened, the structure is present above the height adjusting body 3, so that it is difficult to directly transfer using the above-mentioned crane truck or the like. It is expected that.

Therefore, in this case, the support body 1
The height adjustment body 3 is separated from the support body 1 by the shortening of the telescopic strut body 12 constituting a large stroke or by the lateral movement of the support member 21 of the base body 2 and the subsequent support. The work body 1 can be separated from the base body 2.

That is, first, in the support body 1,
Pipe body 1 of adjustment rod 14 constituting telescopic strut body 12
The guide frame 16 is immersed in the base frame 13 by allowing the guide frame 16 to move in and out of the base frame 13, that is, the guide frame 16 to the base frame 13.

At this time, since the telescopic support 12 is shortened by a large stroke, the height adjusting body 3 is largely lowered, and a large space is formed above the height adjusting body 3. Thus, the height adjustment body 3 can be directly transferred using a crane truck or the like.

Next, in the base body 2, the connection between the seat member 23 and the base member 22 was released, and the interval became large due to the extension of the hydraulic jack disposed between the support member 21 and the base member 22. The traveling means 24 is disposed between the support member 21 and the base member 22, and the upper end of the traveling means 24 is
Connect to 1.

Then, while shortening the hydraulic jack,
By removing this, the traveling means 24 is allowed to travel on the platform member 22, and the driving means 25 is held by the support member 21, and the driving means 25 is connected to the platform member 22, and the driving The base member 2 of the support member 21 by the driving of the means 25
2, that is, the movement of the base member 22 in the arrangement direction is enabled.

The driving means 25 drives the supporting member 2.
When the support 1 moves, the overall lateral movement of the support is realized, and at this time, a large space is formed above the height adjusting body 3 and, therefore, the height adjustment separated from the upper end of the support main body 1. The transfer of the body 3 using a crane truck or the like becomes possible, and in this state, subsequent to the transfer of the height adjustment body 3, the transfer of the support body 1 using a crane truck or the like becomes possible.

This means that when assembling the shoring,
Where there is a large space, the support body 1 is connected to the base body 2, that is, the support member 21 forming the base body 2,
After connecting the height adjustment body 3 to the support body 1 and moving and fixing the support member 21 to the base member 22, it means that the support can be assembled at a predetermined position. .

In the above-mentioned support work, the support body 1 and the base body 2 are transported by using a crane truck or the like after the height adjustment body 3 is removed, which is necessary. In that case, each transfer is a transfer to the next predetermined position.

The condition that the extension base member 22a having a desired length is connected to the base member 22 in the base body 2 is required. In this case, after the height adjustment body 3 is shortened. By moving the support member 21 with respect to the base member 22 and the extension base member 22a, the entire support can be moved to a predetermined arrangement position. Therefore, the base body 2 is fixed at the position after the movement. As a result, the so-called rearrangement of the shoring works is quickly realized.

As described above, in the shoring according to the above-described embodiment, the assembling work and the disassembling work of the shoring work can be easily and quickly performed using a crane truck or the like. Aside from connecting the shoring body 1 to the base body 2, when connecting the height adjusting body 3 to the upper end of the shoring body 1, and expanding and contracting the plurality of screw jacks 33 in the height adjusting body 3. In addition, when a hydraulic jack is arranged between the lower frame 31 and the upper frame 32 of the height adjusting body 3, these operations are performed at a high place. It can be said that it is preferable that a work scaffold is provided.

Therefore, in the illustrated embodiment, it is assumed that a work scaffold frame 4 is connected to the height adjusting body 3 and the support body 1, and a handrail 4 a for security is formed on the work scaffold frame 4. It is going to be.

By the way, the work scaffolding frame 4 connected to the support body 1, that is, the telescopic support 12, is
3 in this case, in this case, the base frame 13
This is advantageous in that the operation of attaching and detaching the stopper 14a to and from the lateral hole of the adjustment rod 14 that is protruded and retracted from the upper end of the rod can be performed.

The handrail 4a formed on the work scaffold frame 4
May be provided in a fixed state, but may be provided so as to be foldable at the base end portion with respect to the work scaffold frame 4, and further, the work scaffold frame 4 itself may be adjusted in height. It may be provided so as to be foldable with respect to the body 3 and the support body 1.

A shoring according to another embodiment of the present invention shown in FIG. 2 is basically similar to the shoring according to the above-described embodiment, and has a main support body 1, a base body 2, and a height. It has an adjusting body 3 and is characterized in that it has a slide moving mechanism 5 for slidingly moving the height adjusting body 3 with respect to the lower support body 1 in the lateral direction.

Therefore, in the illustrated embodiment,
Except where necessary, parts having the same configuration will be denoted by the same reference numerals in the drawings and will not be described in detail, and the following description will focus on the slide moving mechanism 5.

That is, the slide moving mechanism 5 is arranged between the support body 1 and the height adjusting body 3 so that the upper end of the support body 1 is oriented so that the axial direction is horizontal.

and a driving means 54 for moving the movable table 53 along with the rail member 41 and the extended rail member 51a while being held by a.

While the rail member 51 and the seat member 52 are provided integrally with the support in advance, the extension rail member 51a, the moving table 53, and the driving means 54 are provided only when the support is disassembled. It will be prepared as a so-called attachment.

To explain a little, the rail member 51 and the extended rail member 51a are connected to the traveling wheels 5 held by the moving table 53.
3a is formed in a shape capable of receiving and running, and functions as a so-called rail.

The seat member 52 is disposed between the rail member 51 and the height adjusting body 3 during use of the support, and
The height adjusting body 3 is supported from below, and is separated from the upper height adjusting body 3 when the moving table 53 is connected to the height adjusting body 3 to disassemble the support.

As described above, according to the present invention, the height adjusting body is integrated with the plurality of screw jacks by being connected to the upper frame and the lower frame in which lateral displacement between them is prevented. Since it is configured to be able to withstand forces, use a crane truck etc. like the base body and the support body, using a height adjustment body that has been adjusted to a predetermined state on the ground etc. It is possible to carry out the assembling work in the shoring work quickly.

Also, at the time of disassembly of the shoring, it becomes possible to transfer the height-adjusting body by using a crane truck or the like in the same manner as the base body or the shoring main body, so that the dismantling work in the shoring can be performed quickly. Will be squeezed.

Further, according to the present invention, since the telescopic strut constituting the shoring main body is configured to be capable of expanding and contracting with a large stroke, the telescopic strut is maintained in a state of being expanded and contracted by a predetermined amount. By doing so, it becomes possible to make the adjustment amount in the height adjustment body small during the assembling of the shoring.

At the time of disassembly of the shoring, the shoring main body can be greatly shortened by shortening the telescopic strut with a large stroke. Therefore, the shoring main body is connected to the upper end of the shoring main body. As a result, a large space can be formed above the height adjusting body, and as a result, the removal operation using the height adjusting body, the subsequent support body, the base body, and the crane truck can be easily performed. Will be able to do it.

In the present invention, since the base body is configured so that the upper support body can be moved laterally, the so-called whole support can be moved laterally. Not only the removal work using the crane truck or the like of the height adjusting body described above is facilitated, but also the removal work using the crane truck or the like of the support body is facilitated.

In addition to the above, according to the base member, the support body connecting the height adjusting member is connected to the supporting member forming the base member, depending on the length of the base member forming the base member. It is possible to move to a desired position as it is, that is, to assemble the shoring at a new position, that is, to perform a rearrangement work.

Further, according to the present invention, when a slide moving mechanism is provided between the support body and the height adjusting body, only the height adjusting body can slide in the horizontal direction. Thus, a large space is formed above the height adjustment body, and the removal operation of the height adjustment body using a crane truck or the like can be facilitated.

Further, according to the present invention, a work scaffolding frame having a handrail is provided continuously on both or either of the height adjusting body and the support body,
It is possible not only to enable the attachment / detachment operation of the stopper with respect to the adjustment rod at the time of the expansion / contraction adjustment of the screw jack in the height adjustment body or the expansion / contraction adjustment in the support body, but also to perform the operation safely by an operator. It becomes possible to do so.

As a result, according to the present invention, not only the assembling work for use but also the disassembly work after use, the manual work is greatly reduced, and the use of a crane truck or the like is greatly reduced. There is an advantage that the work can be performed safely and quickly.
