Description

[Detailed explanation of the invention] This invention relates to the structure of the mounting part of the wall panel, and its purpose is to prevent the mounting hardware from being exposed to the outside.
To provide a structure for a wall panel mounting part that does not require finishing with repair mortar or the like and has excellent workability.

Conventionally, when installing wall panels made of ALC boards around openings in buildings, as shown in Figs. The reinforcing frame steel material 3 in the direction and the reinforcing frame steel material 4 in the horizontal direction are assembled and installed, and then the wall panel 1 is erected, and the surrounding area is attached to the reinforcing frame steel material using hook bolts 5, washers, and nuts for installation. The most common structure is to fasten it to the However, in this structure, as shown in the drawing, the counter-sunk holes 5a are provided on the surface of the wall panel 1, so after the wall panel 1 is installed, the counter-sunk holes 5a
It was necessary to fill in a with repair mortar, which greatly hindered construction efficiency. Furthermore, after the repair mortar is installed, cracks may occur due to drying shrinkage of the mortar or movement of attachment hardware due to deformation of the building, which may cause problems in terms of appearance.

This idea was developed to solve the above problems, and is a particularly useful structure when installing ALC wall panels. The details will be explained below with reference to illustrated embodiments.

A hole 7 is drilled to a depth of about 150 mm in a direction perpendicular to the edge surface 6 at at least one location at least 100 mm away from the panel corner on both sides of the edge surface 6 of the wall panel 1 made of ALC board. It is formed by

As the mounting fitting, a plate portion 9 may be provided at the base end of a bar-shaped steel material 8 formed by cutting a reinforcing bar as in the embodiments shown in FIGS. 3 and 4.

By the way, the hole 7 can be positioned on either the short side or the long side of the wall panel 1 as needed. If it is provided on the short side, it will be connected to the reinforcing frame steel 4 in the horizontal direction around the opening, and If it is provided in the opening, it will be connected to the reinforcing frame steel 3 in the vertical direction around the opening.

Fig. 5 shows the shear strength of the attachment part when a 100 mm thick ALC plate is used and the diameter and length of the rod-shaped steel material, that is, the reinforcing bar, of the attachment of this invention is varied. If the reinforcing bar diameter is 9mmφ, the installation strength will only be around 200kg regardless of its length.

On the other hand, in the case of 13mmφ, when the length is 100mm, it is 230
However, when the length is increased to 150 mm, the installation strength increases to 320 kg, and no increase in strength is seen even after the length is increased to 200 mm. As mentioned above, the installation strength changes by varying the reinforcing bar diameter and length, but if you use a commonly used 100mm thick ALC board with a diameter of 13mm and a length of 150mm or more, it will weigh more than 300kg. You can gain strength.

The structure of this invention is that a hole is formed in the edge surface of the wall panel in a direction perpendicular to that surface, and a mounting bracket made of bar-shaped steel is inserted into this hole, and its base is attached to the vertical or horizontal direction around the opening. Since it is fixed to the flange surface of the reinforcing frame steel material, compared to the structure of the conventional wall panel mounting part, there is no need to fill the mounting part with repair mortar after installation, and cracks in the repair mortar can be avoided by using the mounting hardware. There is no external exposure, and the structure is free from problems in appearance.
