Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a formwork device used for constructing concrete columns.

[Conventional technology and its issues]

Various formwork devices have been proposed in the past for constructing concrete columns.

Conventional proposals of this kind have the following disadvantages.

That is, in the formwork apparatus according to this type of conventional proposal, the plurality of panels for setting the form of the column have a forming surface with a width dimension that matches the desired form of the column. It is said that it was formed in or quasi-.

Then, the outline of the desired column body is set using the plurality of panels, and the plurality of panels are fixed using a support frame or appropriate fastening means to form a so-called formwork, and the fixed mold is A predetermined amount of concrete is placed within the frame to obtain the desired column body.

Therefore, if the column gradually becomes thinner toward the upper floors, prepare multiple panels for each width dimension set to suit the form of the column that becomes thinner in each chain. Therefore, there is a disadvantage that the number of structural members in the formwork apparatus is increased.

Furthermore, in the above-mentioned conventional proposal, a separator member is placed between opposing panels to ensure the wall thickness of the column, so it goes without saying that the separator member is essential. However, since the separator members are buried, there is an inconvenience in reducing the amount of temporary construction materials.

This invention was invented in view of the above-mentioned circumstances, and its purpose is to reduce the number of structural members in a formwork device and to reduce the amount of temporary materials used to construct concrete columns. It is an object of the present invention to provide a formwork device that is optimal for construction.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the configuration of the mold # device according to the present invention includes a plurality of panels arranged in the vertical direction to set the form of a concrete column. , and a plurality of support frames arranged in the horizontal direction to support the plurality of panels, and the panel has a molded surface with a width dimension larger than the horizontal dimension of the column form set by the panel. The support frame is formed to have a main body part that comes into contact with the back surface of the molding surface, and an auxiliary part that is integrally connected to the main body part. It's a solid thing.

For example, suppose that the panel is formed to have a flat molded surface, and the support frame is formed to have an L-shaped planar shape with a long main body part and a short auxiliary part. Suppose it is formed.

In addition, the support frame has a connection mechanism that allows the main body of one support frame to be separably connected to the auxiliary part of another support frame adjacent to the main body, and the connected main body. It is assumed that it is formed so as to be able to prevent relative movement between it and the auxiliary part.

Furthermore, if necessary, a working scaffold will be connected to the upper end of the panel.

[For production]

Therefore, while setting the outline of a desired column using a plurality of panels, a support frame is attached to the back side of each panel, and adjacent support frames are fixedly connected to each other, so that the plurality of above-mentioned By fixing the panels, a so-called formwork is obtained.

Then, by pouring concrete 1 into the fixed formwork, a desired column body can be obtained.

At this time, if the column is, for example, a square column and is set to gradually become thinner toward the upper floors,
By restricting the effective width of each molding surface of the four panels by one part of 11g of other adjacent panels, the so-called large panels prepared from the beginning can be used as they are.

Further, when pouring concrete into the above-mentioned formwork, a work scaffold connected to one end of the panel is used.

〔Example〕

Hereinafter, the present invention will be described in detail based on the illustrated embodiments.

A mold # device according to an embodiment of the present invention has been proposed to be optimal for constructing a column body consisting of a concrete square column, and as shown in FIGS. 1, a plurality of support frames 2, and connection mechanisms 3 disposed at a plurality of locations.

In addition, FIG. 1 shows an example of a formwork apparatus that is most suitable for a thin type such as column A (see FIG. 2) or a two-way floor.

In addition, the coupling mechanism 3 is shown in FIG. 2, and is shown in its entirety only in one place in the figure, omitted in another place in the figure, and furthermore, in other places in the figure, In two places, illustrations themselves are omitted.

The panel 1 is formed so as to set the form of the column A by setting the outline of the column A on its inner surface, and it not only has self-supporting properties but also has a certain durability. It is constructed so that it can form a so-called formwork.

As the panel 1, what is generally called an aluminum panel is used.

That is, in this embodiment, the panel l is formed so as to have a rectangular plate shape as a whole, and has a main body part 11 that sets the concrete surface of the column A. Become.

The main body portion 11 is provided with a flat molding surface 12 for forming the concrete surface of the column A.

The panel 1 has an edge 13 disposed at the peripheral end of the main body 11 in a so-called frame shape so as to surround the back side of the main body 11 .

and the body portion 11 is located on the inside of the bipedal edge portion 13.
On the back side, there are many reinforcing ribs 14 arranged vertically.
or are connected.

By the way, according to the present invention, the panel 1 is structured so that it is not required to have a separator hole drilled through its wall thickness.

That is, as in the case of the conventional example mentioned above,
This type of panel is generally formed by using a separator to form a so-called formwork.

Therefore, the conventional form of this type of panel is that separator holes penetrating through its wall thickness are appropriately arranged.

However, in this invention, due to the structural specialities of the support frame 2 and the connecting mechanism 3, which will be described later, the panel l is not required to have the separator hole. It is.

Further, in this embodiment, the above-mentioned panel l is a so-called -
Alternatively, from the perspective of the intention of the present invention, a plurality of so-called intermediate panels may be connected in the horizontal direction to form a panel l of a predetermined size. It may be formed as follows.

Next, the support frame 2 is set to support the panel 1, and in this invention, the support frame 2 is formed so that its planar shape is L-shaped. It is assumed that they are arranged in multiple stages on the so-called rear side in the water force direction and in the -L downward direction.

That is, in the present invention, the support frame 2 includes a main body part 21 that comes into contact with the back surface of the panel l, and an auxiliary part 22 that is integrally connected to the end of the main body part 21 at right angles. It is formed in such a way that it moves.

In this embodiment, the main body part 21 is formed to be relatively long, whereas the auxiliary part 2z is formed to be relatively short. The length is determined by the molding size range, and generally speaking, the required molding size range of column A is 600 ~
Since the distance is 1200 m/m, the auxiliary portion 22 is set to tend to be short.

By the way, when supporting the panel l from the so-called back side, the support frames 2 are arranged as a pair, upper and lower, and the main body part 21 of one support frame 2 and the main body part 21 of the other support frame 2 adjacent to the main body part 21 are connected to each other. It is separably connected to the auxiliary part z2 of the support frame 2, and is formed so as to prevent relative movement between the main body part 21 and the auxiliary part 22.

A separable connection between the main body part 21 and the auxiliary part 22 and the main body part 21 and 1. Ancillary section? , 2 is formed such that the prevention of relative movement between them is carried out by the coupling mechanism 3.

In this embodiment, the connection between the support #X frame 2 and the panel l is realized by using a bracket 23.

Here, to explain the above-mentioned coupling mechanism 3 in detail, #
As shown in FIG. 3, the connecting mechanism 3 includes bolts and nuts 3
], a locking piece 32, and a locking pin 33.

The above-mentioned pole donut 31 is a main body part 2 of one support frame 2.
1 and the auxiliary part 22 of another support frame 2 adjacent to the main body part 21
and are separably connected.

In the illustrated example, the specific mode of connection using the bolt nut 31 is as follows:
The threaded part 31 of the bolt 31a is locked to the outside of the auxiliary part 22 of the other support frame 2 with the interposition of the washer 31c.
d projects to the outside of the main body portion 21 of one support frame 2, and a nut 31f is screwed onto the projecting end with a stopper plate 31e interposed therebetween.

It should be noted that the direction in which the E bolt 31a is inserted may, of course, be the opposite direction to that described above, and the structure of the bolt/nut 3] may be as shown in FIG. 4.

That is, the bolt nut 31 shown in FIG.
g, one bracket 31h formed in a horizontal 0-shape so as to rotatably hold the base end side of the butterfly bolt 31g and house the support frame 2 in two upper and lower stages inside, and the butterfly bolt 31g. The other bracket 3 is formed horizontally in a 0-shape so as to fix the nut 31f into which the tip end of the bolt 31g is screwed, and to house the support frame 2 in two upper and lower stages inside.
1i.

The butterfly bolt 31g has a pair of flanges 31j as stoppers fixedly attached to the inner and outer parts of the dowel portion, which is the left end in the figure, of one bracket 3Ih.
This allows the wing bolt 31g to rotate with respect to one of the brackets 31h, and prevents the butterfly bolt 31g from falling off from the other bracket 31h.

Moreover, the other bracket 31i is disposed in a so-called opposed state to the one bracket 31h.

Further, it is said that the main body part 21 of the support frame 2 is disposed in one bracket lh, and the auxiliary part 22 of the support frame 2 is disposed in the third bracket of the other. ,
Of course, it may be the other way around.

Furthermore, in this embodiment, each bracket) 31h
, 31i are inserted with wedges 31k so that each support frame 2 housed inside each of them is stabilized at a predetermined position.

Therefore, in this embodiment, for example, the butterfly bolt 31
By rotating g in the normal direction, a pair of brackets 31h,
While it is possible to connect the support frames 2 disposed between the brackets 31i, it is also possible to separate the support frames 2 between the pair of brackets 31h and 31i by reversely operating the butterfly bolt 31g.

The locking piece 32 is disposed between a pair of upper and lower support frames 2 so that the entire body is in a horizontal state, and its base end 32a is connected to the main body portion 2 of the support frame 2. The tip 32b of the support frame 2 is fixedly installed in between, and its tip 32b is exposed to the auxiliary part 22M of the other support frame 2.

Two notches 32c are formed in parallel at the tip 32b of the locking piece 3z, thereby forming three protrusions 32d.
It is said that it will be formed.

As a result, if an appropriate locking member is present in the L notch 32c, the locking piece 32 is moved.

That is, the relative movement that occurs between the main body portion 21 of one support frame 2 to which the locking piece 32 is fixed and the auxiliary portion 22 of the other support frame 2 on which the appropriate locking member is disposed. Of course, if the notch 32c is formed to have a so-called light gap shape, the notch fi32
This facilitates the presence of the appropriate locking member on c.

The locking pin 33 is similar to the above-mentioned appropriate locking member, and in this embodiment, it is made of a steel bar of an appropriate length.

In this embodiment, the locking pin 33 is attached to the auxiliary portion 22 of the other support frame 2 by MJ! ! i! It is formed so that it can be held freely and its position in the auxiliary part 22 can be changed at appropriate intervals.

That is, in the auxiliary part 22 of the other support frame 2, there are a large number of holes 22a with a diameter of about 20 cm/shoe along the axial direction of the auxiliary part 22 at appropriate intervals, for example, about 50 meters apart. It is said that the hole has been opened.

The locking pin 33 is inserted into the hole 22a.

Therefore, if the spacing between the two notches 32e in the locking piece 32 is, for example, approximately 75 m/m, the position of the tip 32b of the locking piece 32 may be slightly shifted. The hole 22 is located in either one of the two notches 32c.
It becomes possible to aim at the column A, and it becomes possible to insert the locking pin 33, and therefore, when setting the column A, a fairly rough size is adopted. Even if the dimensions of column A vary.

available in most cases.

Note that the locking bottle 33 has a notch 32c and a hole 22.
When inserting into the inside of a, the upper end is fixed with a stopper 33.
Instead of this, it may be formed so that the rR head is placed upwards to prevent it from falling off. The basic structure of the formwork apparatus is that the panel l and the support frame 2 are in this embodiment, as shown in FIG. 1, with appropriate reinforcing members 4. That is, it is reinforced with diagonal members 41 and retaining columns 42, and at the lower end of the reinforcing member 4 there is an adjustment member 43 that enables the overall level adjustment of the formwork device, and an adjustment member 43 that enables the overall level adjustment of the formwork device. Casters 44 are provided in series to enable easy movement.

In addition, in this embodiment, as shown in FIG. 5, a working scaffold 5 is connected to the upper end of the panel l,
Using the work scaffold 5, it is possible to perform work such as pouring concrete into the formwork set by the panel 1.

Therefore, it is desirable that the working scaffold 5 is connected to the upper end of the panel 1 when the so-called formwork is fixedly set.

The formwork device according to this embodiment formed as described above is
It is used as follows.

First, it is assumed that the formwork device is assembled on-site, and in this case, a plurality of panels I are assembled into a formwork that forms the outline of a desired column A by using a plurality of support frames 2.

At this time, the plurality of panels 1 are initially temporarily secured in an upright state by appropriate means, and then the plurality of support frames 2 are fixedly connected to the panels 1.

That is, the connection mechanism 3 connects the main body part 21 of one support frame 2 adjacent to one panel 1 and the auxiliary part 22 of another support frame 2 adjacent to another panel 1 adjacent to this. In addition to realizing a fixed connection in the direction, mutual movement between the main body part 21 and the auxiliary part 22 in the other direction perpendicular to the one direction is prevented. The support frames 2 will be adjacent to the so-called rear side of the panel l in the horizontal and vertical directions, but in this case, each support frame 2 will be adjacent to the bracket 2.
3, it is integrally connected to panel l.

The assembled formwork apparatus may be pre-assembled at a predetermined location, or may be suspended by a crane or the like and moved to a predetermined location after assembly.

After the formwork apparatus is assembled as described above, a predetermined amount of concrete is poured into the formwork.

During the concrete pouring work, a working scaffold 5 is used.

After the poured concrete has hardened, the formwork equipment is so-called repositioned in order to extend the column A made of the concrete to the top J.

That is, the above-mentioned formwork device is raised and the raised formwork device is reused, and the repositioning of the formwork device is as follows:
Lifting work using the above-mentioned crane etc. is permitted.

By the way, when awarding a prize at the time of the above-mentioned rearrangement, the molding device is deformed to a so-called smaller size.

That is, in the case shown in Fig. 6(^), either the column A is relatively thick (see Fig. 2), or the column A is relatively thick (see Fig. 2), or the column A is relatively thick (see Fig.
As shown in B), when the column A is made relatively thin (i$
1), the standing positions of the panels 1 are shifted from each other.

Then, in order to maintain this state, the support frame 2 is placed adjacent to each panel l, and the connecting mechanism 3 is used.
A fixed connection is realized between one support frame 2 and another support frame 2 adjacent thereto, and each support frame 211
By preventing mutual movement at 1, the above-mentioned modification, ie for a thin column A, is carried out.

The above description is based on the case where the column A is a square prism, or alternatively, the column A may have a cross-sectional shape or a different shape such as an ellipse or an ellipse. Of course, it can also be applied in the same way.

(Effects of the Invention) As described above, according to the present invention, by supporting the panel from the back side with a support frame, it is possible to set a predetermined inner space in a concrete column. When constructing a frame column, there is no need to use a variety of sizes of panels, which are the constituent members of the formwork device, and there is an advantage in that the number of temporary members can be reduced.

Further, according to the present invention, since the supporting frames adjacent to the panels are fixedly connected to each other by using the connecting mechanism, when forming the formwork, there is no separator between the opposing panels. This has the advantage of reducing the need for temporary construction materials.
