Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing bar cage for an ALC panel, and more particularly to a reinforcing bar cage for a wide ALC panel which is used by being embedded in a wide ALC panel having a width of 600 mm or more, and a manufacturing method thereof.

[0002]

2. Description of the Related Art To manufacture an ALC panel, a width of 60 is used.
In the case of a normal panel of 0 mm, the depth is about 700 mm,
Reinforcing reinforcing bar cages are arranged at a predetermined interval in a rectangular parallelepiped mold having a width of 1600 mm and a length of 6000 mm, and the raw material slurry is injected and foamed, and after a lapse of a predetermined time, if solidified into a semi-plastic state, removed from the mold. The surface is horizontally cut so that the width becomes 600 mm, and then vertically cut so as to have a desired thickness. After that, it is manufactured by a method of steam curing at high temperature and high pressure in an autoclave, and after cooling, cutting the outer surface as necessary to obtain a product. When manufacturing an ALC panel, a reinforcing bar cage is used as described above. The reinforcing bar cage is a main reinforcing bar in the longitudinal direction depending on the size and required strength of the product, and a horizontal reinforcing bar orthogonal to the main reinforcing bar. The thickness, the number, and the spacing of the reinforcing bars to be used for have been determined. Conventionally, as shown in FIG. 3, a width of 600 mm,
Thickness 100mm, length 3040mm, wind pressure load 120K
In order to manufacture a reinforcing bar cage embedded in a typical ALC panel 13 such as g / m ² , three main bars 1 obtained by cutting a reinforcing bar having a predetermined size, for example, a diameter of 5.5 mm into a length of 3010 mm in one system are predetermined. Weld them with an automatic welding machine by arranging them in parallel at intervals and orthogonally to this main bar 1 and arranging 8 horizontal bars 2 obtained by cutting a reinforcing bar having a predetermined size, for example, a diameter of 5.5 mm to a length of 570 mm at a predetermined interval in parallel. Then, a wire mesh-shaped upper reinforcing bar mat 11 is manufactured, and on the other hand, a lower reinforcing bar mat 12 is manufactured in the same manner with 10 horizontal bars 2, and the upper reinforcing bar mat 11 is turned over so that the horizontal bars 2 are inside. Two mats' transverse lines 2 are piled up in parallel at a predetermined interval so as to face each other and assembled, and both are welded with a pair of united lines 9 each having a diameter of 3.2 mm to produce a cage-shaped rebar cage. is doing.

Further, in order to form an opening at a predetermined position on a large-sized panel, the rebar cage manufactured by cutting off the opening in the rebar mat manufactured as described above is set horizontally in the form, A medium size mold is assembled in the opening and the raw material slurry is injected. After a lapse of a predetermined time, the form is removed, the surface is cut so as to have a predetermined thickness, and then the autoclave is loaded. Thereafter, the same steps as those for a normal panel are performed to obtain a product.

[0004]

As described above, the transverse reinforcement 2 is arranged on the inner surface side in order to increase the bending strength of the ALC panel 13 with the same amount of reinforcement, so that the main reinforcement 1 is formed by ALC.
This is because it is advantageous to place it near the surface of the panel, but on the other hand, if the rebar becomes closer to the surface and the fogging (h) becomes smaller, it is difficult to maintain the positional accuracy of the rebar, so a semi-plastic material is used. When cutting, the reinforcing bar may be exposed on the surface, or the space of bubbles generated near the reinforcing bar during foaming may be exposed. However, in the case where the horizontal bar 2 is arranged in this way, it is necessary to turn over one of the reinforcing bar mats. However, in manufacturing the mat, there is no problem if the width is about 600 mm, but the width is 600 mm or more, for example 150 in width
When manufacturing a rebar cage for a large ALC panel with a width of 0 mm and a length of more than 2500 mm, a complicated device is required in order to invert the rebar mat to an accurate position without causing distortion. However, there is a problem that a large work area is required. Also, when an opening such as a window is provided in the ALC panel, a reinforcing bar mat having different reinforcing bars will be manufactured and combined, which further complicates the process and cuts off the reinforcing bar at the opening. However, there are problems that the cut-out rebar is wasted, and that it is expensive to reuse and dispose.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a rebar cage suitable for manufacturing a wide ALC panel and a method for manufacturing the rebar cage which can be easily manufactured by a simple device without taking a large space and without any trouble. It is what

[0006]

Means for Solving the Problems The present inventor has conducted extensive research to solve the above problems and achieve the above objects, and welds the horizontal bars arranged on both upper and lower main bars so that the horizontal bars are stripped on the same side. The present invention has been completed by finding that the purpose can be achieved by assembling them in the same positional relationship without inverting. That is, the present invention relates to a rebar cage embedded in a wide ALC panel having a width of 600 mm or more, in which two wire mesh-shaped rebar mats welded with horizontal bars orthogonal to a plurality of main bars in the longitudinal direction are fixed in parallel by a joining bar. Two
A reinforcing bar basket for a wide ALC panel, in which each horizontal bar of each reinforcing bar mat is welded to the same side with respect to the main bar, and a plurality of main bars cut into a predetermined size are arranged in parallel at predetermined intervals and cut into a predetermined size. A plurality of horizontal bars are arranged on the arranged main bars in parallel at a predetermined interval so as to be orthogonal to the main bars and welded to produce an upper reinforcing bar mat and a lower reinforcing bar mat, and the upper reinforcing bar mat is placed on the lower reinforcing bar mat. Is a method for manufacturing a rebar cage for a wide ALC panel, in which a plurality of united muscles are welded in parallel at predetermined intervals without being reversed.

[0007]

In the conventional manner, a predetermined number of main bars cut into a predetermined size are arranged in parallel at a predetermined interval, and transverse bars having a predetermined size orthogonal to each other are welded and attached in parallel at a predetermined number at a predetermined interval. The above-mentioned two reinforcing bar mats are parallel to each other at a predetermined interval, and they are superposed as they are without being inverted and welded together by a united bar, which is a manufacturing method thereof. Therefore, it is not necessary to invert one of the reinforcing bar mats, and the work and the device can be simplified and downsized, and the work place can be reduced.
Further, the opening can be formed at once, which does not require any labor, and the waste of rebar and the necessity of reprocessing do not occur.

An ALC panel is used as an outer surface of a building on a surface having lateral streaks on the outside.
Since it may be smaller than the strength on the compression side, there is no practical problem. It should be noted that the diameter and number of rebars can be adjusted according to the design requirements, and it can be applied to the production of ordinary rebar cages for ALC panels, but especially for large panels with large width and length. If applied, the effect is even greater.

It is possible to form the rebar cage 10 by arranging the upper rebar mats 11 in parallel with each other at an interval of, and laying the upper rebar mats 11 in parallel with each other and welding the united bar 9 to the both. The rebar cage of this size has a width of 2400 mm and a length of 3200 m.
It is used for a wide ALC panel having m, a thickness of 125 mm and a wind pressure load of 200 Kg / m ² .

The rebar cage as described above was manufactured as follows.

As shown in FIG. 2 (A), nine main bars 1 cut from a reinforcing bar coil having a diameter of 8 mm for the main bars to a length of 3100 mm are placed at predetermined intervals (250 × 2-300-3) on an assembly table.
50 × 2-300-250 × 2 unit mm).

Fourteen horizontal muscles 2 cut into 00 mm were placed on the main muscle 1 at a predetermined interval (60-150-290-300 × 7-290-1).
The upper reinforcing bar mat 11 was manufactured by arranging parallel to each other in parallel with the main bar 1 at 50-60 unit mm) and welding them. Then, the upper rebar mat 11 is driven by the roller 8 as shown in FIG. 2 (B).
It is transferred to the lifter 5 in the next step shown in (3), raised to a predetermined size by the lifter 5, moved to the uniting place in FIG. 2 (C), and is kept in a horizontal position. Similarly, the lower rebar mat 12 is manufactured. At this time, the mounting bracket 7 of the ALC panel was mounted. After that, it is moved horizontally just below the upper rebar mat 11 so that the predetermined position of both is 5.0 mm in diameter and 7 mm in length.
A reinforcing rod cage 10 was manufactured by welding 45 united muscles 9 of 9 mm.

The rebar cage manufactured in this manner has a width of 25
In a rectangular parallelepiped form having a length of 00 mm, a length of 3300 mm, and a depth of 200 mm, the main rebar 1 of the lower reinforcing bar mat 12 is horizontally arranged via a spacer so that a distance of 20 mm is maintained from the bottom of the form, and a raw material slurry is prepared. Is injected to foam. When the semi-plasticized material is solidified, it is taken out of the mold and the surface is cut so that the semi-plasticized material has a thickness of 125 mm. After that, it was commercialized in the same process as a normal ALC panel.

The panel of the ALC panel manufactured in this manner is a product having a distance from the surface to the main bar surface of 26 mm. For comparison, a product manufactured by a conventional method having a distance from the surface to the main bar of 20 mm is used. A strength test was conducted, but no significant difference was found between the two.

Next, as shown in FIG. 3, the contact plate 3a of the positioning mechanism 3 disposed below the main bar 1 by a predetermined position is lifted to position each main bar 1, 1a, 1b. Then, the horizontal reinforcing bars 2, 2a, 2b are arranged at predetermined positions to manufacture the upper reinforcing bar mat 11, and the lower reinforcing bar mat 12 is manufactured in the same manner.
The upper and lower reinforcing bar mats 11 and 12 were treated in the same manner as in Example 2 to manufacture a reinforcing bar cage having openings. This rebar cage is set in the above-mentioned mold and the raw material slurry is injected and foamed. To form the opening, the middle mold may be assembled, but without using the middle mold, a semi-plastic material is used. The opening may be cut during processing.

[0018]

According to the present invention, since the horizontal reinforcements arranged on both upper and lower main reinforcements are welded on the same side and are combined in parallel without being inverted, the apparatus is simplified. Along with this, the size is reduced, the installation place is small, the number of steps is small, and the opening can be manufactured without the need for waste of the reinforcing bar or reprocessing, and a remarkable effect is recognized.
