Description

[Detailed description of the invention] This invention relates to wall materials, particularly wall materials for external walls used in prefabricated buildings.

Wall materials made of inorganic materials are preferably used to make buildings non-combustible. Among inorganic materials, metals are generally easily rusted and have poor weather resistance, so they are avoided, and those made of water-curable inorganic materials such as slate are preferred as wall materials.

However, slate boards are generally brittle and easily break during transportation and storage. Furthermore, when trying to directly fix slate boards to the framework of a building at a construction site, they tend to crack or collapse, making them difficult to install. Therefore, slate boards can be easily and reliably installed by fixing a frame of a certain thickness on one side of the board in advance at the factory, and then fixing this frame to the building frame at the construction site. An attempt was made to do so.

In this way, by using a slate board with a frame, the slate board will be reinforced, and it will certainly be easier to attach it to the frame. However, when the framed slate boards are stacked and transported or stored, they tend to collapse, and as a result, the slate boards sometimes break. Therefore, it became necessary to further improve this point.

The inventor attempted to attach a metal corrugated plate within the frame of the above-mentioned framed slate plate. As a result, it was found that the slate plates thus obtained do not collapse even when piled up, are reinforced and do not easily break, and are relatively lightweight, which is advantageous.

This idea involves fixing a frame along the periphery of a plate made of a hydraulic inorganic material, fitting a metal corrugated plate into the frame, and making the protruding height of the corrugated plate equal to the height of the frame. This is related to wall materials.

This invention will be explained as follows based on the drawings. FIG. 1 is a partially cutaway perspective view of a wall material according to this invention. FIG. 2 is an enlarged cross-sectional view taken along the line - in FIG. 1. FIG. 3 is a partially cutaway enlarged horizontal sectional view of a building to which the wall material according to the invention is attached.

In FIGS. 1 and 2, the wall material of this invention has a frame 2 fixed to one side of a board 1 made of a hydraulic inorganic material along its periphery, and a corrugated metal plate 3 inside the frame 2. Insert the protruding height 4 of the corrugated sheet 3 into the frame 2.
The height is equal to 5.

The board 1 made of a hydraulic inorganic material is, for example, a slate board made of cement, or a gypsum board made of gypsum. Such boards are usually 5-20mm thick and wide.
The size is 500-1000mm and the length is 500-2000mm. Boards of this size are brittle and break easily, chipping or cracking during use. Therefore, the frame 2 is fixed to one side of the board along its periphery.

The frame 2 may be made of wood, but is preferably made of metal. Among metals, those made of iron or aluminum are preferred. As the frame 2, it is especially convenient to use a long body having a U-shaped cross section and arrange the U-shaped opening toward the outside. The height 5 of frame 2 is usually 10-30mm
It is desirable to do so. The frame 2 is fixed to the board 1 with adhesive or with wood screws, screws 6, etc.

As the metal corrugated plate 3, it is desirable to use a colored galvanized iron plate, generally called a colored iron plate, or a PVC steel plate whose surface is coated with vinyl chloride resin. The protrusion height 4 of the corrugated plate 3, that is, the height of the waves, is equal to the height 5 of the frame 2. The corrugated plate 3 is the frame 2
Although it is desirable to cover the entire inside of the frame 2, if the length or width is insufficient, an uncovered portion may be left inside the frame 2. The corrugated plate 3 is fixed to the inorganic material plate 1 with wood screws or screws 7 at appropriate locations on the periphery or inside thereof.

The wall material according to this invention is used as shown in FIG. That is, first, bolts b are inserted and fixed between columns on which two shaped steels a are erected back to back to form the frame of the building. There,
Wall materials related to this idea will be attached. At this time, board 1
The wall material is positioned so that the outer side of the frame 2 is in contact with the side surface of the section steel a. Also, at this time, there will be a gap between the adjacent wall materials, so insert the rectangular retaining piece c through the gap, rotate the retaining piece c within the gap so that the long side is horizontal, and then insert the rectangular retaining piece c into the gap. It is placed across the openings of the frame 2 and fixed on the bolt b. In this way, the wall material is attached to the frame of the building using the retaining pieces c, with the frame 2 and metal corrugated sheet 3 attached to the inside. The gap between wall materials is filled with a sponge-like elastic material d
and a hard elastic plate e.

In the wall material of this invention, the frame 2 is fixed to one side of the board 1 made of a water-curable inorganic material along its periphery, which prevents the edge from chipping or cracking during handling. . Further, since the metal corrugated plate 3 is fitted into the frame, the plate 1 is further reinforced by the corrugated plate 3 and becomes difficult to break. in addition,
Since the protruding height of the corrugated plate 3 was made equal to the height of the frame 2,
Even if the corrugated plate 3 is attached, the apparent volume of the wall material does not change, and the weight does not increase by that proportion, so even if the wall materials are stacked, the load will not collapse. Therefore, this wall material is convenient for storage and transportation. Thus, the wall material of this invention provides various advantages.
