DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a large number of lightweight cellular concrete boards to the left and right and up and down of a structural frame of a building to form a wall surface.

[0002]

2. Description of the Related Art Conventionally, a large number of lightweight cellular concrete boards (hereinafter, referred to as ALC boards) have been attached to a structural body of a building at right and left and up and down to form a wall surface.

In this case, the mounting method of the ALC plate is as follows.
Many of the vertical insertion muscle construction methods as shown in FIGS. 9 to 11 are employed.

In this vertical insertion method, first, a self-weight receiving plate 103 is welded to a ruler angle 102 attached to a structural frame 101 of a building.
Using the nail hole 104 of No. 03, while temporarily fixing the upper edge of the ALC plate 106 with the nail 105, the AL of the first layer
The C plate 106a is erected (see FIG. 11).

[0005] At this time, C-shaped grooves 107 are formed on the left and right edges of the ALC plate 106 over the entire length thereof (see FIG. 11). By embedding eyes, a circular mortar insertion groove 108 is formed between the ALC plates 106.

Next, with the joint reinforcing bar 109 inserted into the circular mortar insertion groove 108 formed between the ALC plates 106, the joint reinforcing bar 109 is fixed to the dead weight receiving plate 103 by welding (FIG. 11). reference).

After that, the mortar 110 is poured into the mortar insertion groove 108, and the mortar 110
And cure. As a guide for curing, JASS
According to the description in No. 21, "After mortar filling, no harmful vibration and impact must be given for 24 hours (48 hours in winter)."

After the curing of the mortar 110 filled in the first-layer ALC board 106a is completed, the second-layer ALC board 106b is erected above the refractory material 111 while filling the mortar 110, and the same operation as described above is performed. By repeating
A wall surface is formed by the LC plate 106 (see FIG. 9).

[0009]

However, according to the above-mentioned conventional method for mounting an ALC plate, the ALC plate adjacent to the ALC
The mortar insertion groove 108 formed between the plates 106
The mortar insertion groove 108 is filled with a large amount of mortar 110 because the mortar 110 is present over the entire length of the left and right edges of the LC plate 106, which makes the work troublesome.
There is a case where 10 is clogged on the way and the filling becomes insufficient. In addition, the mortar 110 is
In the lower part of 8, the mortar 110 tends to flow outward from the gap between the ALC plates due to the pressure of the mortar 110 from its own weight from above, and there is concern that the formed wall surface will be soiled.

Further, in the conventional ALC plate mounting method, the mortar insertion groove 10 serving as a filling port for the mortar 110 is provided.
8, the upper end of the ALC plate 106 exists at the upper edge of the ALC plate 106,
Moreover, there is no AL on the left and right edges of the ALC plate 106.
Since there is no member that restricts the ingress and egress of the C plate 106, the filling operation of the mortar 110 of the first ALC plate 106a is completed, and the upper second layer that gives vibration until the curing is completed. The ALC plate 106b of the eye could not be erected, and the work efficiency was poor.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and the gist of the present invention is that a large number of ALC plates are attached to a structural frame of a building on the left, right, up and down, and the wall surface is formed. In the method of mounting the ALC plate to be formed,
Grooves for mortar insertion are formed in upper and lower portions of the left and right edges of the ALC plate, and a mortar injection port communicating with the upper end of the mortar insertion groove in the lower portion is formed from the plate surface, and , Forming a ridge or a ridge that engages with another ALC plate adjacent to the middle portion of the left and right wood edges,
The ALC plate is moved left and right and up and down in a state in which the convex and concave stripes are engaged with the structural frame of the building, and joint reinforcing bars are inserted into mortar insertion grooves formed between adjacent ALC plates. The mortar is then temporarily fixed to the structural frame of many buildings, and then the mortar is poured from the mortar inlet, and the mortar insertion groove formed in the lower part of the upper ALC plate and the upper part of the lower ALC plate. The mortar and the mortar are simultaneously filled in the mortar insertion groove formed in the ALC plate, and then the mortar is cured.

[0012]

According to the method of mounting the ALC plate according to the present invention,
Since the mortar insertion grooves are formed only on the upper and lower portions of the left and right edges of the ALC plate to be mounted, the amount of mortar to be filled into the mortar insertion grooves is reduced, and the work is facilitated. The annoyance of clogging in the middle disappears. Also, since the mortar filling length is short,
The pressure from above due to the weight of the mortar is small, and AL
There is no fear of the mortar flowing out from the gap between the C plates.

Further, according to the mounting method of the ALC plate according to the present invention, since the mortar injection port is formed on the plate surface of the ALC plate, the ALC plate can be attached to the structural frame of a large number of buildings left and right and up and down. After temporarily fixing the mortar, the mortar can be filled into the mortar insertion groove through the mortar injection port at the same time. Since the ridge or the ridge that engages with the plate is formed, it is possible to prevent the ALC plate from being displaced by the vibration during the erection or filling of the mortar, and the work efficiency is dramatically improved. .
