Description

[Detailed Description of the Invention] This invention relates to an ALC board mounting structure for attaching an ALC board (lightweight cellular concrete board) to a building frame.

Conventionally, as shown in Figure 1, the method for attaching ALC board wall panels to a building frame is to first drill a hole 2 in the thickness direction of 7 to 8 mm on the surface of an ALC board 1, and then insert the After fixing the ALC board 1 to the rim 4 of the building frame or the studs of the pillars 5 by penetrating nails 3 or screws from 2,
A method has been adopted in which holes 2 into which nails 3 or screws have been driven are filled with mortar 5.

This filling mortar is a special mortar that has the same appearance and water absorption properties as ALC so as not to cause uneven coating in the surface finish.

In this way, after attaching the ALC board to the exterior wall, an interior material such as plasterboard 6 is attached to the rim 4 from the opposite side with nails 7 on the indoor side.
was installed.

However, with this method, when nailing interior materials such as gypsum board 6, there are many cases where the filling mortar 5 filled in the ALC board falls off due to the impact of nailing.
Therefore, it was necessary to perform the filling process again with mortar.

Moreover, the contractors for the exterior wall materials and interior materials are generally different.
Moreover, since the construction opening was different, redoing the work became a troublesome problem.

This idea solves the above problems all at once.
The purpose is to propose a structure for installing ALC boards in which the filling mortar will not come off even if the interior materials are nailed and installed.

The gist of this idea is that the interior materials are nailed to the inside surface of the building frame, and the ALC board is attached to the outside surface by penetrating the nails through holes drilled in the surface. The ALC board mounting structure is characterized in that the holes after the nails are filled with mortar are filled with a cushioning material interposed between the nails and the mortar.

With this structure, even if the interior material is nailed to the opposite side of the building frame, such as the same rim where the ALC board was installed, after the ALC board has been installed, the impact force will be absorbed by the cushioning material, and the filling mortar will easily fall off. do not.

The cushioning material used in this invention is not particularly limited, but fiber waste, sponge, rubber, synthetic resin foam, cardboard pieces, etc. are recommended.

As for the method of inserting cushioning material, ■ After penetrating the ALC board with nails such as nails or screws, place cushioning material on the head of the nail, fill it with mortar, and close the hole. Method: (1) A cushioning material is pasted on the head of the nail in advance, and after the material is penetrated, the hole is filled with mortar and the hole is closed.

In the case of (2), hollow rubber, synthetic resin foam, etc., which have excellent resilience to return to their original shape when hammered, are suitable as the cushioning material.

Also, in the case of screws, it is convenient to make cuts in the cushioning material along the driver grooves of the screws so that they can be screwed in using a screwdriver.

This will be explained below with reference to the embodiments shown in the drawings.

In the structure shown in Fig. 2, a hole 2 is provided on the surface of the ALC board 1, and a nail 3 is driven through this hole to the base rim 4 of the ALC board 1.
A cushioning material 8 made of polyethylene foam is placed on the upper surface of the head of the nail 3 that has reached the bottom of the hole 2, and a cushioning material 8 made of polyethylene foam is placed on top of the cushioning material 8. Perlite, cement.

A filling mortar 5 made of ALC powder or the like is filled to close the hole 2 and the wall plate of the ALC board 1 is attached.

Thereafter, a gypsum board 6, which is an interior material, is attached from the opposite side of the rim 4 with nails 7.

With this structure, we were able to greatly reduce the chance of the filling mortar falling off due to the impact caused by nailing the interior materials.

Under the same conditions, when no cushioning material was inserted, the ring mortar fell off by about 25 to 30%, but in the structure of the example in which a 2 mm thick polyethylene foam cushioning material was inserted, almost no falling off was observed. I couldn't.

The thickness of the cushioning material 5 depends on the dimensions of the nail, the type of the cushioning material, etc., but generally the purpose of this invention can be achieved with a thickness of about 2 to 3 mm.

The cushioning material only needs to be placed on the upper surface of the nail head, but in some cases it may be attached.

In FIG. 3, a cushioning material 8 made of polyethylene foam is pasted on the upper surface of the head of the nail 3 in advance.

By driving the nails 3 directly into the ALC board 1, the ALC board 1 can be attached to the building frame with a structure similar to that shown in FIG.

Even if you attach a cushioning material to the top surface of the screw head and use it to attach the wallboard, the same effect as with nails can be obtained.

In this case, as described above, a cut is made in the cushioning material along the driver groove of the screw head.

This invention is as described above, and by interposing a simple cushioning material between the head of the nail and the filling mortar, the falling of the filling mortar can be greatly reduced.

Therefore, it has a great effect on improving the construction efficiency of buildings.
