Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides lightweight aerated concrete panels, particularly
It relates to ALC panels, and more specifically to ALC panels with embedded fittings for panel mounting.

Conventionally, various methods have been used to attach this type of wall panel to a building frame using mounting hardware such as bolts. need,
There were problems in terms of design, workability, etc.

To solve these problems, for example, as shown in FIG.
A bar-shaped steel material 6 is inserted into a hole 7 formed perpendicularly to that surface.
The applicant's previous idea (Utility Model Application Publication No. 1985-85008) of inserting the mounting nut 20a into the mounting bracket 20 as shown in Fig. 2 is used. There is a method of embedding the panel inside the panel and attaching the panel from the indoor surface using bolts 22 at the construction site.

However, due to constraints arising from the strength of the mounting part, the method shown in Figure 1 is used for panels on middle and lower floors where the wind pressure acting on the wall is small, and panels above and below openings where the wind load bearing area per panel is small. The range is limited, and the method shown in Figure 2
When a panel is cut and used during on-site construction, the position of the embedded metal fitting with the mounting nut 20a cannot be changed, so it is difficult to adapt to this situation, so it is difficult to be used widely in the ALC field.

The present invention solves the above problems at the same time, and provides an ALC plate that has high strength and allows flexible on-site construction.

The configuration which is the gist of the present invention is as described in the claims section, and details thereof will be explained below based on the illustrated embodiments.

FIG. 3 shows one embodiment of the present invention, in which a hollow steel pipe 5 opening toward the edge face 1a inside the ALC panel 1 is fixed to the reinforcing reinforcing bar 2 in advance by welding or using a special fixing tool, and the panel It is buried over almost the entire length in the width direction or length direction.

ALC panel 1 is a steel pipe 5 that opens toward the small end.
By inserting and fitting the bar-shaped steel material 6a in the vertical direction to the edge face 1a, the bar-shaped steel material 6a is supported in the out-of-plane direction. In addition to the method via , various designs of fasteners are possible.

The steel pipe 5 can be easily buried inside the lightweight foamed concrete material by placing the reinforcing reinforcing bars 2 to which it is fixed in a formwork, filling it with lightweight foamed concrete material (plastic material), and hardening and molding the plastic material. It is something. The direction of the steel pipe 5 is shown in Fig. 5 1 or 2.
As shown in the figure, whether the opening face 1a is on the short side or the long side may be determined according to the design of the fastener, and its length is determined in the direction in which the bar-shaped steel material 6a is inserted and fitted. It is preferable that the length be slightly shorter than the total length. As shown in Fig. 6, the steel pipe 5 is buried in communication with the end face of the mounting side in the vertical direction, so no matter where it is cut on the vertical face in the direction at the construction site, this cut surface 1b Steel pipe 5 appearing in
The bar-shaped steel material 6a can be inserted and fitted into the panel, and there is no problem in mounting the panel. This is a very effective technique when ALC panels are cut and used at the construction site.

The present invention has a structure in which a steel pipe for installation is buried inside the panel in advance in a factory, and the steel pipe communicates with the panel edge surface on the installation side in the vertical direction, and the steel pipes are the same in the length direction. Since the panel has a cross-sectional shape, the panel can be constructed without any problem in use even if the panel is cut on any plane perpendicular to the direction in which the steel pipe is buried at the construction site.

In this way, the present invention has special effects in terms of implementation,
This provides an extremely useful ALC panel that could not previously exist.
