Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a scaffolding fitting used for assembling a scaffold at a construction site.

[0002]

2. Description of the Related Art Conventionally, a scaffold is indispensable in the construction work of a building. In this scaffold assembling work, the conventional method of assembling the wall panel 2 of ALC or the like on the steel frame 1 as shown in FIG. 9 embeds the long nut 3 into the joint width between the upper and lower wall panels 2 via the angle material 6, and A scaffold connection bolt 4 was attached to the nut 3 and a scaffold (not shown) was fixed with a bolt or the like.

In the above-mentioned conventional example, the ALC wall panel 2 is cut out and a long nut 3 is embedded therein.
After the construction work is completed, the scaffold is disassembled by repairing the notched portion 5 of the wall panel 2, coking and painting while removing the scaffold after the construction work is completed.

[0004] However, repairing, caulking, and painting the notch 5 while removing the scaffold is very troublesome.

[0005] In addition, traces of scaffolding joints remain in places of the completed building, which has impaired the aesthetics of the building.

[0006]

Therefore, a block-shaped scaffolding fitting 11 having the same thickness as the joint width of the building wall panel as shown in FIG. 10 has been devised. Therefore, the unit cost per kg is more than twice as much as that of ordinary steel, so that the cost is high, and since the solid material is used, the weight is heavy, and the groove 12 is not easily milled.

[0007] Further, as shown in FIG. 11, a scaffolding fitting 21 having a reduced weight is also used. Since the scaffold tether 21 shown in FIG. 11 is formed by bending only one plate material, it is possible to reduce the material cost, reduce the weight, and manufacture only by pressing and tapping. There is an advantage that it can be easily performed. On the other hand, the strength is insufficient, the strength specified by the Health and Safety Law cannot be obtained, and the scaffolding connection bolts 4 also have different neck 22 portions (see FIG. 9) due to differences in the thickness of the ALC wall panels. Various dimensions must be prepared. When the ALC wall panel is thick, if the neck 22 of the scaffold connection bolt 4 is lengthened, the strength of the scaffold connection bolt 4 is significantly reduced in a round bar portion within 10 mm of the standard joint size, and the strength becomes a problem. There was a disadvantage of becoming.

This invention is intended to solve the above-mentioned drawbacks of the prior art, and it is an object of the present invention to provide a scaffolding fitting which can be easily manufactured and greatly reduced in cost, while eliminating concerns about strength.

[0009]

In other words, the scaffolding fitting of the present invention has a body plate whose both ends in the width direction are bent in a U-shape along the length direction to have the same thickness as the joint width of the building wall panel. And U at one end in the length direction of the main body plate
An additional plate superimposed on the inside of the V-shape, and a female screw portion for attaching a scaffold connection bolt formed between the main body plate and the additional plate, and the other end in the longitudinal direction of the main body plate is attached to the main body plate. The plate is bent inwardly in a U-shape.

[0010]

[Function] Since the scaffolding fitting of the present invention is configured as described above, it can be easily manufactured with only a small number of materials in a pressing process alone, so that not only is mass productivity good, but also significant cost reduction is achieved. Became possible.

In addition, since a thick iron plate can be used, even when welding is performed with a strong current when welding the groove welding connection portion to the angle material, welding failure does not occur.

[0012] Further, since the scaffolding joint fitting processed into the same width as the joint width by the rib is embedded in the joint width between the upper and lower wall panels, it also serves as a ruler of the joint width of the wall panel. Repair of wall panels in dismantling work becomes unnecessary, and scaffolding dismantling work can be performed quickly, and there is no appearance defect such as discoloration of repaired parts due to repair of wall panels, greatly improving the finished state of the building Was done.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the scaffolding fitting of the present invention will be described below in detail with reference to the drawings.

As shown in FIG. 5, a wall panel 2 such as ALC is assembled to a steel frame 1 with an angle member 6 interposed therebetween. In the joint width between the upper and lower wall panels 2, a scaffolding connection fitting 31 processed to the same thickness as the joint width is embedded.

As shown in FIGS. 1 to 4, the scaffold tethering bracket 31 is processed into a predetermined width and a length proportional to the thickness of the wall panel 2, and both ends in the width direction are lengthened. The main body plate 32 is bent in a U-shape along the direction and has the same thickness as the joint width of the building wall panel. One end of the body plate 32 in the length direction is provided with the body plate 3.
The additional plate 34 is overlapped by caulking via a rivet 35 the inside of the pair of ribs 33 bent in the U-shape.

The main body plate 31 and the additional plate 34
A female screw portion 36 for mounting the scaffolding connection bolt 37 is formed between them. The female screw portion 36 is appropriately changed according to the size of the scaffold connection bolt 37 to be attached.

The other end in the longitudinal direction of the main body plate 32 is similarly bent inside the U-shape of the main body plate at the time of bending into the U-shape, and the connecting portion 38 is welded to the angle member 6. It is desirable to keep it. 39
Are notches for facilitating formation of the female screw portion 36;
Numeral 0 denotes a projection for making the main body plate 32 the same thickness as the joint width of the building wall panel.

As shown in FIGS. 6 and 7, the scaffold connecting bolt 37 has a male screw 41 at one end and a nut portion 42 at the other end. Then, the male screw 41 is screwed to the female screw portion 36 of the scaffolding connection fitting 31, and a bolt for attaching the scaffold is attached to the nut portion 42.

In the figure, since the nut portion 42 of the scaffold connection bolt 37 is formed in two steps, even if one type of wrench is used, the wrench can be attached to either the thin nut portion 43 or the thick nut portion 44. Can be applied and turned.

The manufacturing process of the scaffolding fitting 31 will be described with reference to FIG. A long plate material is used, and cut into several types of main plate 32 lengths determined according to the thickness of the wall panel 2. At the same time, both ends in the width direction of the main body plate 32 are bent in a U-shape along the length direction to form a pair of ribs 33 and a connecting portion 38 to the angle member 6, and a scaffold connecting bolt 37 is attached. Of the female screw portion 36 (substantially semicircle), a projection 40 and a caulking hole 45 are formed.

As described above, since a long plate material is used and cut into several kinds of main plate 32 lengths determined in accordance with the thickness of the wall panel 2, it is rich in mass productivity. In addition, since wasteful scraps are not generated in the long plate material, the cost can be reduced.

On the other hand, separately from the formation of the main body plate 32, an additional plate 34 is prepared. This additional plate 3
4 also has a half of the female screw portion 36 for attaching the scaffold connection bolt 37 and a caulking hole 45. 3
5 is a rivet.

Since the scaffolding fitting 31 of the present invention can be easily manufactured by using only a small number of materials as described above and only by the pressing process, it is possible to greatly reduce the cost.

Next, when using the scaffolding fitting of the present invention, at the stage when the steel frame 1 is assembled and the skeleton is formed, the angle member 6 is welded to the upper portion of the steel frame 1 so as to slightly protrude outside thereof. The wall panel 2 made of ALC is attached to the steel frame 1 via the angle member 6 (see FIG. 4). Each of the wall panels 2 is attached to the steel frame 1 at a joint width of a predetermined vertical interval (10 mm). The scaffolding fittings 31 are set at the joint at predetermined intervals, and the rear connecting portion 38 is connected to the angle. Welded to material 6. The scaffold is attached with a scaffold connection bolt 37 to the scaffold connection fitting 31 and is fixed to the nut portion 42 of the scaffold connection bolt 37 with a bolt.

The construction work is performed using the scaffold, and after the construction work is completed, the scaffold connecting bolts 37 and the scaffold fixing bolts are removed from the scaffold tether 31, and disassembled. 2. Caulking and painting are performed.

At this time, the scaffolding fittings 31 are accommodated within the joint width of the vertical interval (10 mm) of the wall panel 2, so that repair of the wall panel 2 is unnecessary.

The width of the scaffold tether 31 is set to be easy to handle or to be AL when the ALC wall panel is mounted.
In order not to damage the wall panel made of C, it is desirable to be about 30 to 40 mm.

[0028]

[Effects of the Invention] The scaffolding fitting of the present invention is constructed as described above, and therefore can be easily manufactured with only a small number of materials in a pressing process alone. Cost reduction has become possible.

Further, since a thick iron plate can be used, when welding the joint for groove welding to the angle material, even a welding by a strong current does not melt to cause poor welding.

Further, since the scaffolding fittings processed into the same width as the joint width by the ribs are embedded within the joint width between the upper and lower wall panels, repair of the wall panels in the scaffold dismantling work becomes unnecessary, and the scaffold disassembly becomes unnecessary. The work can be performed quickly, and there is no appearance defect such as discoloration of the repaired part due to the repair of the wall panel, and the finished state of the building has been greatly improved.
