Description

DETAILED DESCRIPTION OF THE INVENTION This invention is an 11-diameter aerated concrete panel (11 diameters) cured with high temperature and high pressure steam, mainly used for curtain walls.
(hereinafter abbreviated as ALC panel)'Jj! : Regarding the precast panel used.

ALC panels are widely used because they are lightweight, have excellent heat insulation properties, and can be constructed in a short period of time.However, they have the drawbacks of low impact strength and easy chipping. For this reason, it is difficult to process the edges and provide a waterproof riser etc. in order to improve waterproof performance due to the possibility of chipping.7j0 This invention was devised to eliminate all of the above-mentioned drawbacks. The purpose of this is to strengthen the area around the ALC panel and to improve the waterproof performance of the joints.

The precast panel according to the present invention is made by integrally providing a metal frame around the periphery of a plate made of ALC.

This invention will be explained below using one drawing +1 jA3
As shown in FIG. 1, the precast panel according to the present invention is composed of an ALC panel 1 and a metal frame 2 integrally provided at the side portions of the ALC panel. .

As the scrap metal frame, a bent metal plate may be used, or an extruded aluminum or the like may be used.

ALC panel 1 is shown in Fig. 2, Fig. 3, and +'*' s.
As shown in Figure 4, fitting grooves 3 are formed on the four sides by cutting, etc.
is provided. On the other hand, a protruding piece is provided on the back surface of the metal frame 2, and the protruding piece 4 is fitted into the fitting groove 3 to be integrated. Further, by applying an adhesive 5 between the lightweight cellular concrete and the metal frame or using nails 8, it is possible to further strengthen the identification power.

As shown in Fig. 3, there are horizontal joints in the precast panel with such a configuration, and 11 frames 2A and 2B are placed on the lower part of the Dobe ALC panel 1 and the upper part of the lower ALC panel 1 in approximately concave shapes.
is installed. These upper and lower panels are shaped like
Ring material 6. The back-up material 7 has a sharp edge.

When constructing a panel, it is necessary to erect it in the direction of the arrow as shown in Figure 2134, but because ALC has low local compressive strength, it is prone to compressive failure at the part where it contacts the ground.

In addition, during the installation of panel metalwork, the edges of the panels collide with the scaffolding and chisel structure, causing chipping, which has become a problem.

However, by reinforcing the periphery of the ALC panel with a metal frame, it becomes strong against local compression and can prevent chipping. Therefore, it is possible to process the entire edge of the ALC panel in a complicated manner.

FIG. 5 shows all the concrete application examples of the metal frame. A lower metal frame 2C in the shape of a disconnection cursor, which has a protrusion 9 provided at the lower part of the upper ALC panel l and protrudes downward on the outdoor side;
The upper metal frame 2D is provided in the upper part of the lower ALC panel l and has an upper metal frame 2D in the shape of a cutout cursor and has a protrusion 10 that projects upward on the indoor side.

In such a configuration, an equal pressure space with the outside air is formed between the protrusion 9 and the protrusion 10, which alleviates the blowing of wind and prevents the intrusion of water by the rising force. Ru.

・What is shown in Fig. 6 is the structure of a horizontal joint when molded joint material is used.

Upper metal parts 2E and 5B are provided at the lower part of the upper ALC panel 1 and have a concave tffl tap 11A and have a circular cross section.
A recessed groove 11B2 is provided on the upper part of the LC panel 1.
The upper metal 2F has a substantially U-shaped cross section.

Molded joint materials 12A and 12B are fitted into the recessed grooves, and can achieve a high waterproof function.

Of course, as shown in FIG. 7, metal frame configurations shown by 2G and 2H, which combine waterproof uprights and molded joint materials, are also possible.

Since the metal frame described above is manufactured by extrusion molding or bending, the aforementioned protrusions and recessed grooves can be easily formed.

The present invention has the above-mentioned configuration, and is a precast panel that is significantly effective against chipping of Lt ALC panels and has dramatically improved waterproof performance.
