DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of temporary scaffolding building materials which are erected outside a building such as a house and form a working scaffold, and form, for example, a one-sided scaffold or a main scaffold. Is something that can be used for

[0002]

BACKGROUND ART A plurality of building materials made of steel pipes are:
Each lower end is mounted and connected to a base such as a rotating base, jack base, etc., and is erected outside the building, and is connected to each other with roots or cloth materials, and at a predetermined position in the length direction. A cloth plate receiving bracket, a scaffold receiving bracket, a handrail, and the like are attached, whereby a temporary scaffold for a building such as a house is assembled.

Conventionally, when mounting members such as a cloth material, a cloth plate receiving bracket, and a scaffold receiving bracket are attached to predetermined positions of a building material, the position from the roots is a fixed length called a stupid bar. The mounting position of the member to be mounted is determined using a rod or a scale, and the member to be mounted is mounted at each mounting position. According to this, it takes a lot of labor and time, and therefore, there is a problem in terms of work efficiency, and since such work must be performed at each construction site, such a problem occurs at each construction site. was there.

[0004] As a prior art which can solve such a problem, Japanese Utility Model Application Laid-Open No. 61-140034 and Japanese Patent Application Laid-Open No. 61-179958 are disclosed.
No. is known. In the former, a concave portion is formed at a predetermined position of a building material, and a protruding portion is formed on an inner peripheral surface of a clamp which is a coupling device of an end portion of a cloth plate receiving bracket or the like, and the protruding portion is fitted into the concave portion. The clamps are combined so as to be connected to predetermined positions of the building material. In the latter, a fixing hole is formed at a predetermined position of the building material, a fixing protrusion is provided on a clamp at an end portion of a cloth plate receiving bracket or the like, and the fixing protrusion is inserted into the fixing hole to attach the clamp to a predetermined position of the building material. We are trying to connect to the position. According to these conventional techniques, the recessed portion and the fixing hole serve as a mark indicating a position where a member to be mounted such as a cloth plate receiving bracket is to be mounted on the building material, and the work of mounting the mounted member on the building material is performed. It can be done efficiently.

[0005]

However, according to these prior arts, a projection or a fixing projection must be provided on a clamp, which is a fastener for a member to be attached, so that the conventional clamp cannot be used as it is. was there. Also, when the clamp is connected to the building material, the recesses and fixing holes are hidden inside the clamp because they are inside the clamp, and after assembling the temporary scaffold, the inspector or the like can confirm that the mounting position of the member to be mounted is accurate. There is also a problem that it is difficult to confirm whether or not it is a position, and it is more difficult to confirm this in a building site where a mixture of building materials that are not provided with recesses or fixing holes are used. become.

[0006] An object of the present invention is to use a conventional fastener as it is, and to easily confirm whether or not a member to be mounted is mounted at an accurate position after assembling a temporary scaffold. It provides building materials for temporary scaffolding.

[0007]

In order to achieve this object, a plurality of temporary scaffolding building materials according to the present invention are connected to each other and are erected on the outside of a building, and are attached to a mounting bracket such as a cloth plate receiving bracket. In the temporary scaffolding building material to which the members are attached to form a working scaffold, the position corresponds to the mounting position where the member to be mounted is to be mounted, and is shifted from this mounting position in the length direction of the building material, and A mark portion indicating the mounting position is provided at a position where the coupling member of the attachment member is separated from the coupling member when the coupling member is coupled.

In the present invention, since the mark portion is provided at a position displaced in the length direction of the building material from the mounting position of the member to be mounted and deviated from the coupling, the building for coupling the coupling of the member to be mounted is provided. The location of the base material is a normal location where no projections or the like are provided as in the conventional art, and therefore, the conventional fastener can be used as it is.

In addition, even after the joining tool is joined to the building material to assemble the temporary scaffold, the mark portion appears outside without being hidden by the joining tool, so that the attached member can be accurately positioned at a predetermined position of the building material. It can be easily confirmed whether or not it is attached to the device.

[0010] The mark portion provided on the building material may be a convex portion protruding in the outer diameter direction of the building material, a concave portion recessed in the inner diameter direction of the building material, or a mark made on the outer surface of the building material by marking. It may be a notch mark such as a line with a mark, or a paint mark in which paint is applied to the outer surface of the building material.

In the case where the mark portion is a convex portion protruding in the outer diameter direction of the building material, the convex portion may be formed by extruding a part of the building material or the like. May be formed by fixing the material of another member to the outer surface of the building material by welding, screwing, or the like.

In the case where the mark portion is a convex portion, when the connecting member of the member to be mounted is mounted on the convex portion and connected to the building material, the connecting portion can be supported by the convex portion. This prevents the fastener from sliding.

When the fastener is placed on the projection as described above, if the projection is a small projection that is short in the circumferential direction of the building material, the support of the fastener is ensured. Therefore, it is preferable to provide a plurality of the small protrusions in the circumferential direction of the building material.

Further, in order to more reliably support the joint, the convex portion may be a ring-shaped projection continuous over the entire circumference of the building material.

[0015] The structure and type of the fastener are arbitrary, and even when the fastener is a clamp, the shape and shape of the clamp
Although the structure is arbitrary, the coupling device includes a clamp body, a clamping member rotatably connected to one end of the clamp body, and a clamping member for clamping the other end of the clamp body and the clamping member with a gap therebetween. In the case of a clamp having a fastening member such as an attached bolt, the length of the projection in the circumferential direction of the building material may be smaller than this gap. By doing so, the tightening of the clamping body between the clamp body and the holding member by the tightening member is slightly loosened, and the mounted member is rotated in the circumferential direction of the building material so that the position of the convex portion and the gap coincide with each other. The clamp can be moved along the building material while being made, and the position of the clamp (the mounting position of the member to be mounted) can be changed without separating the clamp from the building material.

Even when the mark portion is a concave portion which is depressed in the building material inner diameter direction, the clamp can be moved along the building material, and the position of the clamp can be easily changed. .

In the above, the member to be attached to which the fastener such as a clamp is coupled to the building material using the mark as a mark may be any member as long as it can be attached to the building material.
For example, it is a root stud, a cloth plate receiving bracket, a scaffold receiving bracket, a handrail receiving bracket, a handrail pipe, a cloth pipe, a wall connection, or the like.

[0018] The construction material for temporary scaffolding according to the present invention comprises:
It can be used as a component of the one-sided scaffold and also as a component of the present scaffold.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a temporary scaffold after assembling. The temporary scaffold includes a plurality of bases 1 such as jack bases arranged outside a building, and lower ends of the bases 1 are connected to these bases 1. And a plurality of building materials 2 erected outside the building, roots 3 laid between the lower portions of the building materials 2, and a hand laid between the upper portions of the building materials 2. A sliding material 4, a cloth plate receiving bracket 5 attached to the building material 2, a cloth plate 6 serving as a scaffold spanned between two adjacent cloth plate receiving brackets 5, and a plurality of building materials A large strut 7 is installed diagonally crossing 2 and a wall joint 8 whose tip abuts or is connected to the building. Building materials 2
The roots 3, handrails 4, large struts 7, etc. are made of steel pipe.

The root studs 3, handrails 4, cloth plate receiving brackets 5 and the like are members to be attached to the building material 2 via couplings, so that they are members to be attached to the building material 2. .

FIG. 2 shows the building material 2 to which the cloth plate receiving bracket 5 is attached. In this building material 2,
A plurality of protrusions 9 serving as marks for the mounting position of the member to be mounted are formed at a plurality of locations separated in the longitudinal direction of the building material. It is set to match the mounting interval of the mounted member that has become possible. 3 and 4 show the projection 9 in an enlarged manner. The projection 9 in this embodiment is a small projection 10 which is short in the circumferential direction of the building material. Four building materials are provided at equal intervals in the circumferential direction. Each small protrusion 10
Is formed by extruding the building material 2 from the inside to the outside, whereby small protrusions 10 protruding in the building material outer diameter direction are provided on the building material 2.

After the lower end of the building material 2 is mounted and connected to a base 1 such as the jack base shown in FIG. 1 and the height level of the building material 2 is adjusted, the length of the building material 2 is adjusted. The height position of each small projection 10 formed apart in the vertical direction is shifted downward from the predetermined mounting position of the mounting target member in the building material length direction, and It is a position where it comes off from the coupling of the members.

That is, when the member to be mounted is the cloth plate receiving bracket 5 having the horizontal member 5A and the diagonal member 5B as shown in FIG. 2, each of the horizontal member 5A and the diagonal member 5B on the building material side is used. The clamp 11, which is a fastener provided at the end, is connected to the building material 2
When the cloth plate receiving bracket 5 is attached to a predetermined mounting position of the building material 2, the height position of the clamp 11 of the horizontal member 5A becomes the predetermined mounting position of the cloth plate receiving bracket 5. , Horizontal material 5A at this time
Of the small protrusion 10 is located above the small protrusion 10.
Are not hidden inside the clamp 11.

For this reason, the place of the building material 2 to which the clamp 11 is connected is a normal place without a projection or the like. Therefore, the clamp 11 may be the one used so far.
There is no need to make any work on the clamp 11. Also, after assembling the temporary scaffold using a large number of building materials 2 and the like, the inspector or the like visually recognizes the small protrusions 10, whereby the member to be attached such as the cloth plate receiving bracket 5 is attached to a predetermined position. Can be easily checked.

Further, by setting the distance from the predetermined mounting position of the member to be mounted to the upper surface of the small projection 10 to be half or substantially half of the height of the clamp 11, the mounting position of the member to be mounted can be accurately or almost exactly adjusted. The clamp 11 can be placed on the small protrusion 10 while securing the distance, thereby enabling the clamp 11 to be supported by the small protrusion 10 and preventing the clamp 11 from sliding along the building material 2. it can.

The number of the small projections 1 is made plural in the circumferential direction of the building material as in this embodiment,
0 can reliably support the clamp 11.

FIG. 5 shows a case in which the cloth plate receiving brackets 5 of these cloth plates 6 are mounted close to the building material 2 in order to provide two cloth plates 6 at right angles on the temporary scaffold. . In this case, the brackets 11 of the horizontal members 5 </ b> A of both brackets 5 are joined to the building material 2 with a small protrusion 10 therebetween in the length direction of the building material 2. Also in this case, since the small projections 10 appear between the upper and lower two brackets 11, it is possible to confirm whether or not the mounting positions of these brackets 5 are accurate or almost accurate.

The embodiment shown in FIGS. 6 and 7 is a case where the convex portion 9 as a mark provided on the building material 2 is a ring-shaped projection 12 continuous over the entire circumference of the building material. The ring-shaped projection 12 is formed by fitting a ring member to the outer periphery of the building material 2 and fixing the ring member to the building material 2 by welding or screws. According to this embodiment, when a coupling tool such as a clamp for a member to be mounted is placed on the ring-shaped projection 12, the contact area becomes larger than that of the small projection 10, so that the support of the coupling tool is more effective. Can be done.

The ring-shaped projection can also be formed by extruding from the inside to the outside over the entire circumference of the building material 2.

In the embodiment shown in FIG. 8, a clamp 11, which is a fastener for a member to be mounted, includes a clamp body 11A, a clamping member 11C rotatably connected to one end of the clamp body 11A by a pin 11B, In the case of a clamp including a tightening bolt 11D and a nut 11E for tightening the other end of the main body 11A and the holding member 11C with a gap S therebetween, the small protrusion 13 provided as the convex portion 9 on the building material 2 This is a case where the length of the building material in the circumferential direction is smaller than the gap S. When the small projection 13 is smaller than the gap S, the tightening of the clamp body 11A and the holding member 11C by the tightening bolt 11D and the nut 11E is slightly loosened, and the mounted member or the building material 2 is rotated. When the position of the small protrusion 13 and the gap S are matched, the clamp 11 can be moved along the building material 2 while passing through the small protrusion 13, and the clamp 11 can be attached without being separated from the building material 2. The position of the member can be easily changed.

The same operation and effect can be obtained even when a plurality of small protrusions are provided apart in the circumferential direction of the building material, the total length of these small protrusions in the circumferential direction of the building material is larger than the gap S. It is obtained by keeping it small.

In the embodiment shown in FIG. 9, the mark provided on the building material 2 is a concave portion 14 which is depressed in the building material inner diameter direction. According to this embodiment as well, it is possible to move the fastener along the building material 2 without separating the fastener such as the clamp of the mounted member from the building material 2, and to determine the position of the mounted member. Changes can be made easily. In addition, a plurality of recesses 14 are formed in the circumferential direction of the building material 2 or continuously over the entire circumference of the building material 2 so that the inspector or the like can visually recognize the recess 14 from any direction with respect to the building material 2. It can also be formed as desired.

In each of the above embodiments, when the mark portion provided on the building material 2 is a convex portion 9 as shown in FIGS.
Since the projecting amount of the projecting portion 9 does not need to be so large, when a large number of building materials 2 are loaded on a truck bed and transported to the construction site, when the building material 2 is pulled out from the bed, the projecting portions 9 Does not hinder work.
