Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a lightweight cellular concrete panel with embedded mounting hardware. The purpose is to provide a lightweight aerated concrete panel with high attachment strength to a building frame.

Traditional lightweight aerated concrete panels (below
The structure of the mounting bracket for the ALC panel is as follows:
For example, as shown in Figure 4a, a through hole 2 is bored in the ALC panel 1 formed, a mounting bracket 3 with a female screw hole is inserted, and the gap is filled with mortar with one end opened on one surface. Alternatively, as shown in Fig. 4b, the mounting bracket 3 of the long nut is welded to the reinforcing bar 5 via the anchor bar 4, etc., and this is buried to form the ALC panel. something is known.

Screw and fasten bolts to these mounting brackets 3,
When the ALC panel 1 is fixed to the main body frame 7,
The structure shown in Figure 4a has the disadvantage that the concrete around the mounting bracket is easily destroyed when an external force in the direction of the arrow is applied because it is directly fixed and supported by the ALC panel, which has relatively low strength. Traces 2' remained on the surface, causing cracks and water leaks. In the case shown in Fig. 4b, there is no risk of spot digging marks remaining on the panel surface, cracks, or water leakage, but the rigidity of the mounting part of the mounting bracket 3 is small, so if an external force is applied as shown by the arrow, the local It was easy to cause physical damage.

This invention was made in view of the above-mentioned problems, and the embedded metal fitting has at least two planes that are orthogonal to each other, and a nut is fixed to one of the planes, and a nut is embedded in the panel and has two planes on both surfaces of the panel. The embedded metal fittings are fixed across multiple reinforcing bars placed on the front side of one panel and multiple reinforcing bars placed on the front side of the other panel, and are embedded in the panel together with the nuts. This is a lightweight aerated concrete panel with special features. The embedded fitting having at least two orthogonal planes has, for example, a U-shaped, L-shaped, or H-shaped cross section. That is, such as channel steel with a U-shaped cross section, which consists of a flat part and bent parts bent at right angles from both sides of the flat part, and L-shaped steel, which consists of a flat part and bent parts bent from one side edge of the flat part, Alternatively, it may be something like an H-beam made of orthogonal planes. In short, it is sufficient that the structure has at least two orthogonal planes and has high three-dimensional steel properties.

The present invention will be explained below with reference to illustrated embodiments.

For example, the embedded metal fittings 11 in the ALC panel 1 shown in FIG.
and bent portions 10, 10 bent at right angles from both edges thereof.
It is a channel steel with a U-shaped cross section. Further, reinforcing bars 8, 8' are embedded on both surface sides of the panel.
The embedded fitting 11 has a U-shaped cross section facing the top and bottom of the panel, and the upper and lower edges of the bent parts 10, 10 are connected to the two reinforcing bars 8, 8 on the upper side of the panel and the two reinforcing bars 8, 8 on the lower side of the panel.
It is fixed by welding to the reinforcing bars 8' and 8' of the book.
In this invention, the embedded metal fitting 11 has a plurality of reinforcement bars 8, 8 on the surface side of one panel and a plurality of reinforcing bars 8', 8' on the surface side of the other panel, which are embedded in the panel.
8'.

A long nut 12, which is a mounting fitting, is welded to the upper center of the U-shaped inner surface of the flat part 9 of the embedded fitting 11, facing upward, and one end thereof is open to the upper surface of the ALC plate 1. Also, in this example,
A long nut 13 for lifting the panel during construction is welded to the outer surface of the flat portion 9 with an opening facing the thickness end surface of the ALC panel 1. The embedded fittings 11 and long nuts 12 for mounting are installed at required locations on the ALC panel 1, for example, in the four partitions as shown in FIG.
The panel is configured. Note that the position where the long nut 12 is fixed to the embedded fitting 11 is not limited to the inside of the U-shape. It may be fixed to other positions outside the U-shape.

This ALC panel has the above configuration, and when the bolt 6 is screwed into the long nut 12 and attached to the main body frame 7, as shown in FIG. 3, the external force acting on the long nut 12 through the bolt 6 is Metal fittings 11
The embedded metal fitting 11 consists of a flat part 9 and two bent parts 10 perpendicular to the flat part 9, and has high rigidity in the three-dimensional direction, and also has a plurality of reinforcing bars arranged on both the upper and lower sides. 8, 8, 8', and 8', there is no risk of deformation or movement due to the forces in the lateral and longitudinal directions of the long nut 12, and the external force that acts on the reinforcing bars 8 , 8' to the entire panel, so there is no localized force acting on the ALC panel, and the force is not applied to the mounting brackets or the ALC panel.
This can prevent damage to the ALC panel. In addition, all the mounting fittings are welded to reinforcing bars before the panel is molded, so there is no risk of digging marks remaining on the panel surface, cracks, or water leakage.

This invention is as described above, and this panel has high mounting strength and excellent water-stopping properties. Furthermore, since the mounting brackets are fixed to the reinforcing bars and arranged during panel molding, no processing is required after the panel is molded, so the panel cost is also low.
