DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing member for lightweight cellular concrete panels, and can be used, for example, for autoclaved cellular concrete panels.

[0002]

2. Description of the Related Art In recent years, unit houses have been constructed in which a living room or the like constituting a house is manufactured as a house unit in a factory, and these house units are transported to a site and assembled. In such a unit house, an autoclave-cured aerated concrete panel has been used as a building material for an outer wall.

[0003] The autoclaved aerated concrete panel is made of cement and silica sand as main raw materials, and a concrete slurry mixed with air bubbles is poured into a forming mold in which reinforcing bars are arranged, and is temporarily cured. After that, the molded panel is manufactured by steam curing in a high-temperature, high-pressure autoclave. The reinforcing member is configured by arranging mesh bars above and below a main bar made of an angle member, a square bar, a flat bar, or the like.

[0004]

The angle material and the like are as follows:
Since it is manufactured by hot working, black scale, a kind of rust, is formed on the surface. Therefore, prior to manufacturing the autoclaved aerated concrete panel, the reinforcing material has been subjected to a treatment such as pickling to remove the black scale in addition to the degreasing treatment. Therefore, the work of removing the black scale takes time and effort, and the production efficiency of the autoclaved aerated concrete panel is reduced.

Accordingly, an object of the present invention is to provide a reinforcing member for a lightweight cellular concrete panel which can omit an operation of removing black scale by pickling or the like, thereby improving the panel manufacturing efficiency.

[0006]

The reinforcing member of the lightweight cellular concrete panel according to the present invention is manufactured by bridging a number of short wires between a plurality of long wires arranged in parallel. A plurality of ladder bars are combined so that the short wires are parallel to each other in the vertical and horizontal directions of the panel to form a main bar, and mesh bars are arranged on the upper and lower surfaces of the main bar, respectively. The lightweight cellular concrete panel includes a normal pressure cured lightweight cellular concrete panel, an autoclave cured cellular concrete panel, and the like.

[0007]

Since the wire constituting the reinforcing member according to the present invention is not manufactured by hot working, no black scale is generated, and the work of removing black scale such as pickling is not required.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a reinforcing material for an autoclave-cured cellular concrete panel will be described together with an example of a manufacturing method up to an autoclave-cured cellular concrete panel. First, as shown in FIG. 1, two long wires 11A, such as small-diameter round bars, are arranged in parallel, and a number of short wires 11B made of the same material as the wires 11A are bridged at equal intervals. Long ladder streaks 14 by welding
Is prepared. Next, the ladder muscle 14 is cut into lengths corresponding to the horizontal and vertical dimensions of the panel 12 (see FIG. 2) to produce a first ladder muscle 14A and a second ladder muscle 14B. Each of these ladder bars 14A and 14B is composed of two parallel long wires 11A and a number of short wires 11B bridged over them.
And

Next, as shown in FIG. 2, three first ladder bars 14A are prepared, and they are arranged so as to be located near and in the middle of both ends of the panel 12 in the longitudinal direction 15, respectively. The second ladder bars 14B are arranged (near both ends in the horizontal direction of the panel 12), and these ladder bars 14A, 14B are connected by welding or the like to form the main bars 16. In this main line 16,
As shown, the long wires 11A are substantially on the same plane, and the short wires 11B are parallel to each other.

Next, as shown in FIG. 3, mesh bars 17 are arranged above and below the main bars 16, respectively, and fixed by welding or the like, thereby producing a reinforcing member 18 of this embodiment. Next, when manufacturing the autoclaved aerated concrete panel, the reinforcing member 18 to be used is subjected to degreasing treatment and washing with water. In the case of the reinforcing member 18, since the wires 11A and 11B having no rust such as black scale are used, pickling is unnecessary.

Next, as shown in FIG. 4, the reinforcing member 18 is disposed in a molding frame 19, and after the lightweight foam slurry 20 is cast therein, it is cured for a predetermined time and is temporarily cured. next,
The molded panel 12 is conveyed into an autoclave (not shown), and subjected to autoclave curing at, for example, 180 ° C., 10 atm, and 8 hours. After this autoclave curing,
Remove panel 12 from the autoclave. As shown in FIG. 5, the obtained panel 12 has a wire rod 18
11A and 11B are buried in the vertical, horizontal and thickness directions of the panel 12.

According to the reinforcing member 18 for an autoclaved aerated concrete panel of the above embodiment, since the wires 11A and 11B constituting the reinforcing member 18 are not manufactured by hot working, black scale is generated. Therefore, there is no need to remove black scale such as pickling before manufacturing the panel 12. Therefore, compared with the conventional panel manufacturing method, the number of steps is reduced,
Increases manufacturing efficiency.

The wires 11A and 11B of the ladder bars 14A and 14B are
It is embedded in the vertical, horizontal and thickness directions of the panel 12, so that this reinforcing material can be used without using a conventional angle material.
18 provides a sufficient reinforcing effect of the panel 12. In particular, in the case of a multifunctional panel in which the specific gravity of the concrete in the panel is varied in the thickness direction, a large number of short wires 11B exist in the thickness direction of the panel. The reinforcing members 18 can effectively prevent peeling of the panel in the thickness direction.

In the above embodiment, a long and continuous ladder streak 14 is prepared and cut in accordance with the dimensions of the panel 12 in the horizontal direction 13 and the vertical direction 15 to obtain the first and second ladder lines. Ladder muscles 14A and 14B were obtained, but panel 12
Prepare the long wires 11A cut in accordance with the dimensions of the horizontal direction 13 and the vertical direction 15 of these, and these wires 11A arranged in parallel
A number of short wires 11B over the first ladder bar 14A
Alternatively, the second ladder muscle 14B may be manufactured.

According to the reinforcing member for a lightweight cellular concrete panel according to the present invention, the operation of removing black scale by pickling or the like can be omitted, thereby increasing the panel manufacturing efficiency.
