Description

[Detailed description of the invention] The present invention relates to a wallboard mounting method and mounting device.

Previously, wall panels for the exterior of buildings were installed from the outside of the building using scaffolding, which required preparation, transportation, storage, and assembly and dismantling of the scaffolding. , it was expensive and took a long time. When constructing a new building in close proximity to an existing building, it is extremely difficult to install exterior wall panels, and if the barrel body, which is made of concrete, is unavoidably left as is, spray sealing will not be possible and rain protection will be inadequate. There was a pause that caused a rain leak.

This invention solves the above-mentioned drawbacks of the conventional art, and allows wall panels to be installed from the indoor side of a building.1. To provide a wall board mounting method and a mounting device that do not require scaffolding on the outdoor side and allow the wall board to be installed without any trouble even when there is little clearance between the wall board and an existing building.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the figure, ▪ indicates an exterior wall plate, which is formed by bending joints 3a and 3b on both left and right edges of a wall plate main body 2 in the form of a stepped plate. (When collectively referred to as the joint part 3, the same applies to other parts hereinafter.) The joint part 3a is a bent piece part 4a that is connected to the edge of the wall board body and faces indoors.
A folded piece 5a is connected to the bent piece and faces toward the center of the wall board body 2, and a folded piece 5a is connected to the indoor side of the folded piece and projects laterally beyond the edge of the wall board body. It consists of a back plate piece part 6a. A protrusion 7 is provided near the center of the back plate piece 6a to protrude toward the outdoors. Note that the wall board main body 2 may have a flat plate shape or a bent plate shape. Moreover, the joint part 3b has the same structure as the joint part 3a except that it does not have the protrusion 7, and corresponding parts are shown with reference numerals and detailed explanations are omitted. The joint portion 3a and the joint portion 3b have a dimensional relationship that allows them to fit together as shown in the third figure. On the other hand, 8 is a C-shaped steel fixed to an architectural structure such as a pillar of a building, and one to several C-beams are provided per first floor of a building, and 9 is a lip portion thereof. 1
Reference numeral 0a denotes a left-side fastener, which is made by bending both ends of a plate-like steel plate 12a having an opening Lea opening toward the right at its tip end downward, and forming a latching piece 18a connected to the opening 11a. Anti-slip portion 1 provided at the end opposite to the opening 11a
4 is formed. Reference numeral 15 denotes a rotation prevention piece formed by bending a part of the right edge near the center of the plate-shaped body 12a upward. Note that in the present invention, up, down, left, and right refer to directions when each part of the several phrase state is viewed from the indoor side.

Reference numeral 10b denotes a right-side latching metal fitting, which has a similar configuration to the left-side latching metal fitting tOa except that the overall length is short (it does not have the anti-slip piece 14 and the anti-rotation piece 15), and corresponding parts are marked with numerals. 16 is a C-shaped steel 8.
This is a tightening plate having a length such that both ends thereof engage with the back surfaces of both lip portions 9 of.

The left side latching fitting 10a and the right side latching fitting 10b are provided with holes through which the bolts 17 pass, and the tightening plate 16 is provided with a female threaded portion 18 into which the bolts 17 are screwed.

To install a wall board using the apparatus configured as described above, first, a plurality of wall boards 1 are placed with their back plate pieces 6 facing the outdoor side surface 20 of the C-shaped steel 8, and the joint parts 3 are mutually connected. The two (right and left) latching metal fittings toa1 are fitted to the joint parts 3 in the fitted state of the adjacent wall plates.
The respective openings tta and ttb of the tob are engaged from the left and right, and the locking pieces 13a and 13b are engaged with the outdoor side surfaces of the folding pieces 5a and 51j. A clamping plate 16 is inserted into the C-shaped steel 8 from between both lip portions and turned so that both ends thereof face the back surfaces of both lip portions 9. Next, the double-fold stopper 10a110
b are placed on top of each other so as to straddle both the cup portions 9 of the C-shaped steel 8, and the anti-slip portion 14 is placed on the indoor side surface 2 of the C-shaped steel 8.
1, and then tighten the bolt 17 with both folding fittings toa and tab.
The fixing of the joint part is completed by passing through the bolt and screwing it into the female threaded part 18 of the clamping plate 16, and by tightening this bolt, fixing the double-fold stoppers 10a, 10b and the clamping plate 16 to the C-shaped steel 8. . After that, install each joint part in the same manner. The above work can be carried out indoors by workers on the floor of each floor of the building or on a stepladder or the like set up on this floor. Note that if the wall board 1 is long, it may be hung using a crane or the like, and it is sufficient that there is a slight gap between it and an adjacent building. After the bolt 17 has been tightened, the joint portion 3 is prevented from shifting toward the outdoors from the C-shaped steel 8 by the anti-slip piece 14, and the ends of the double-fold stoppers 10a and 10b are still open due to the anti-rotation piece 15. This prevents the joint portion 3 from coming off.

After installing the exterior wall plate 1 as described above, the concrete plate forming the main part of the wall is attached to the C-beam 8 etc. from the indoor side. Note that this work is not necessary when the wall plate 1 is used as the main body of the wall, such as the wall of a warehouse, for example.

In the second embodiment, the hooking piece 13 is bent downward;
The joint part 3 can be firmly fixed to the C-shaped steel 8 without any gaps due to the elasticity of the Al 18b and the anti-slip piece part 14. Note that the anti-slip portion 14 may be provided on both bending fittings 10a and 10b. Also, instead of providing the anti-rotation piece 15, the double-fold stopper 10a1
The lOb may be provided with a concavo-convex portion that engages when overlapping, or the rotation prevention piece 15 may be omitted when using a dog-sized bolt 17 or a two-wood bolt. In the above embodiment, the back plate piece 6a of the joint part
This invention has the advantage of excellent sealing performance against rainwater etc. due to the pressure contact of the protrusion 7 provided on the back plate piece 6b. The present invention can also be applied to a wall plate having a joint portion having a cross-sectional shape different from that of the joint portion 3 described above.

FIG. 5 shows another embodiment of the present invention, in which a double-fold stopper 10
a, the lob is in the form of a flat plate, and a square plate that engages with the lip part 9 on the outdoor side as the anti-slip part 14 is welded to the lower side of the left side latch 10a, and is the same as that in Fig. 4. Parts or equivalent parts are shown with the same reference numerals.
The working procedure and wall plate mounting operation are the same as in the previous embodiment.

In the following, this invention has been explained for the case where the wall board fi (-1) of a building is used, but the present invention can also be applied to the case where a fence is built using the above wall board 1 as a wall board, and it can be applied to the case where the wall board 1 is used as a wall board near the boundary of the site. Even if there is an existing building on the adjacent property, a fence can be erected from within the premises to the boundary without any hindrance.

As explained above, according to the present invention, the latch fastener (m.

Fix the tool to the joint part of the wall board and tighten it to the tightening plate.C
The wall panels can be attached from the indoor side or inside the site by simply fixing them to the shaped steel, and there is no need for scaffolding for attaching the wall panels, making it economical and shortening the construction period. Even if there is little clearance between the wall plate and the wall plate, it can be installed without any problem.
