Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wallboard mounting method and mounting device.

Traditionally, wall panels for the exterior of buildings were installed from the outside of the building using scaffolding, which required preparation, transportation, and storage of materials for constructing the scaffolding, as well as assembly and dismantling of the scaffolding. , which was expensive and took a long time. Furthermore, when constructing a new building close to an existing building, it is always difficult to install exterior wall panels, and if the main body of the wall, which is concrete panels, is unavoidably left, spray sealing is not possible, making it impossible to prevent rain. There were problems with rain leaks due to deficiencies.

This invention solves the above-mentioned conventional drawbacks,
Wallboard installation allows wallboards to be installed from the indoor side of the building, there is no need to set up scaffolding on the outdoor side, and wallboards can be installed without any problems even if there is little clearance between the building and the existing building. The present invention seeks to provide a method and a mounting device.

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

In the figure, reference numeral 1 designates an exterior wall plate, which is formed by bending joint portions 3a and 3b on the left and right side edges of a wall plate main body 2 in the form of a stepped plate. (When collectively referred to as joint 3, the same applies to other parts hereinafter.) Joint part 3a consists of a bent piece part 4a that is connected to the edge of the wall board body and faces indoors, and A folded piece 5a that is connected to the folded piece and faces the center of the wall board body 2, and a back plate piece that is connected to the indoor side of the folded piece and that projects laterally beyond the edge of the wall board body. It consists of a part 6a. There is a protrusion 7 near the center of the back plate piece 6a.
is protruding toward the outside. In addition, wall board body 2
may be in the form of a flat plate or a bent plate. Also, the joint part 3b has the same structure as the joint part 3a except that it does not have the protrusion 7, and the corresponding part has the attached number b.
, and detailed explanation will be 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. Reference numeral 10a denotes a left-side latching metal fitting, which is made by bending both ends of a plate-like body 12a made of a steel plate, which has an opening 11a opening toward the right at its tip end, and a latching piece 13a connected to the opening 11a; Opening 1
A stopper piece 14 is provided at the end opposite to 1a. 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. In addition, the top, bottom, left, and right in the present invention are as follows:
This refers to the direction in which each part is viewed from the indoor side when installed. 1
Reference numeral 0b designates a right side latch, which has the same structure as the left side latch 10a, except that it has a shorter overall length and does not have the anti-slip portion 14 and the anti-rotation piece 15, and corresponding parts are marked with the numeral b. , and detailed explanation will be omitted. Reference numeral 16 denotes a tightening plate having a length such that both ends engage with the back surfaces of both lip portions 9 of the C-shaped steel 8. 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, the plurality of wall boards 1 are placed so that the back plate piece 6 faces the outdoor side surface 20 of the C-shaped steel 8, and the joint parts 3 are mutually connected. The openings 11a and 11b of both (right and left) latching fittings 10a and 10b are engaged from the left and right with the joint parts 3 in the fitted state of adjacent wall plates. , the hooking pieces 13a, 13b are engaged with the outdoor side surfaces of the folding pieces 5a, 5b. Inside the C-shaped steel 8 is a tightening plate 16.
is inserted from between both lip parts and turned so that both ends thereof face the back surfaces of both lip parts 9. Next, the two latch fittings 10a and 10b are placed on top of each other so as to straddle both lip portions 9 of the C-shaped steel 8, and the anti-slip portion 14 is engaged with the indoor side surface 21 of the C-shaped steel 8. , the bolt 17 is passed through both the latching metal fittings 10a, 10b and screwed into the female threaded part 18 of the clamping plate 16, and by tightening this bolt, the both latching metal fittings 10a, 10b and the clamping plate 16 are connected to the C-shaped steel 8. If it is firmly fixed, the joint part is completely fixed. 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. Furthermore, wall board 1
If the structure is long, it can be lifted using a crane or the like, and there only needs to be a small gap between it and the adjacent building. After the bolt 17 is tightened, the joint portion 3 is prevented from shifting toward the outdoors from the C-shaped steel 8 by the anti-slip portion 14, and the tips of both latches 10a and 10b are opened by the anti-rotation portion 15. This prevents the joint portion 3 from coming off.

After the exterior wall board 1 is installed as described above, the concrete board or the like that forms the main part of the wall is attached to the C-beam 8 or the like from the indoor side. Note that this operation is not necessary when only the wall plate 1 is used as the main body of the wall, such as the wall of a warehouse, for example.

The above embodiment has the advantage that the joint part 3 can be firmly fixed to the C-shaped steel 8 without any gaps due to the elasticity of the downwardly bent latching pieces 13a and 13b and the anti-slip part 14. be. The anti-slip portion 14 has both locking fittings 10a,
10b. Furthermore, instead of providing the anti-rotation piece 15, both the locking fittings 10a and 10b may be provided with uneven portions that engage when stacked, or when using a large bolt 17 or when using two bolts. For example, the anti-rotation piece 15 may be omitted. Further, the above embodiment has the advantage that the projection 7 provided on the back plate piece 6a of the joint part is pressed against the back plate piece 6b, so that the sealing property against rainwater etc. is excellent. The invention can also be applied to a wall plate without this protrusion 7 or having a joint portion having a cross-sectional shape different from that of the joint portion 3, such as an angular shape.

FIG. 5 shows another embodiment of the present invention, in which both latching metal fittings 10a and 10b are made into a flat plate shape, and the left side latching metal fitting 10a is a square plate that engages with the lip portion 9 on the outdoor side as the anti-slip portion 14. The structure is welded to the lower side of the wall plate, and the same or equivalent parts as in FIG. .

The present invention has been described above with respect to the case of installing a wall plate of a building, but the present invention can also be applied to the case where a fence is built using the above wall plate 1 as a wall plate. Even in such cases, a fence can be erected from within the premises to near the boundary without any hindrance.

As explained above, according to the present invention, the wall board can be attached from the indoor side or the inside of the site by the simple operation of engaging the hanging bracket with the joint part of the wall board, tightening it to the clamping plate, and fixing it to the C-shaped steel. It is economical and the construction period is shortened because there is no need for scaffolding for wall board installation, and the wall board can be installed without any problems even when there is little clearance between adjacent buildings.
