Abstract

PROBLEM TO BE SOLVED: To dispense with an iron plate for connecting bolts by burying a lath having multiple flat plate-like ribs in a lightweight cellular concrete panel, connecting one-end sections of bolts inserted from the back face or surface side of the lightweight cellular concrete panel to the flat plate-like ribs, and connecting the other ends to a structural skeleton for fitting. SOLUTION: A lath 2 having multiple flat plate-like ribs 3 is buried in a lightweight cellular concrete panel 1. Screws 12 are inserted into screw insertion holes 10a formed on one side of piece angles 10 via washers 11, and the screws 12 are screwed to a structural skeleton such as a beam 13 to fix the piece angles 10. Tapping screws 15 are inserted into screw insertion holes 10b formed on the side via washers 14, and tips are screwed into the flat plate-like ribs 3 from the back face 1a of the panel 1 to fix the piece angles 10 to the structural skeleton such as the beam 13. Not only the high-strength lightweight cellular concrete panel 1 can be obtained by the ribs 3, but also an iron plate for connecting bolts is not required, and the panel 1 is easily manufactured.

2. Description of the Related Art There is known a lightweight cellular concrete panel in which a metal lath or a reinforcing bar is buried to increase the strength. Then, such a lightweight cellular concrete panel is fixed to a metal lath or a reinforcing bar in advance by welding or the like, and a bolt is connected to the iron plate to be attached to a structural body such as a beam. Therefore, such a method of mounting a lightweight cellular concrete panel requires an iron plate and requires an operation for fixing the iron plate.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for mounting a lightweight cellular concrete panel which can be mounted on a structural body such as a beam without specially providing an iron plate for connecting bolts. It is in.

[0004]

In the method for mounting a lightweight cellular concrete panel according to the present invention, a lath having a plurality of flat ribs is buried in the lightweight cellular concrete panel, and a back or front surface of the lightweight cellular concrete panel is provided. One end of the bolt is inserted from the side, one end of the bolt is connected to the flat rib, and the other end of the bolt is connected to a structural body such as a beam, and the lightweight cellular concrete panel is mounted.

According to the method for mounting a lightweight cellular concrete panel of the present invention, one end of a bolt for mounting the panel is connected to the rib of the lath.

[0006]

FIG. 1 shows one embodiment of a method for mounting a lightweight cellular concrete panel according to the present invention. In the illustrated lightweight cellular concrete panel 1, a lath 2 is embedded. The lath 2 has a plurality of flat ribs 3. The lath 2 is formed by making a cut in accordance with the mesh size as a whole, leaving strip-shaped flat plate portions at a plurality of portions of the steel plate, like the rib lath, and extending both ends of the steel plate.

In this lightweight cellular concrete panel 1, a plurality of laths 2 are arranged in a formwork, a foamed concrete slurry is injected into the lath 2 to perform molding, and a semi-plastic molded body is taken out in a semi-cured state. Is cut by a piano wire or the like into an appropriate thickness so as to include the lath 2, and the cut is subjected to autoclave curing.

As shown in FIG. 2, the lightweight cellular concrete panel 1 has a screw 12 inserted into a screw insertion hole 10a formed in one piece of the piece angle 10 via a washer 11, and the screw 12 is inserted. The piece angle 10 is fixed to the beam 13 or the like by being screwed to a structural body such as the beam 13, and a tapping screw 15 is inserted through a washer 14 into a screw insertion hole 10 b formed in the other piece of the piece angle 10, Connect the tip of the screw 15 to the lightweight cellular concrete panel 1
Is fixed to a structural body such as the beam 13 by screwing from the back surface 1a of the first member 3 and screwing it into the flat rib 3 of the lath 2.

The lightweight cellular concrete panel 1
Can be mounted not only by the mounting method shown in FIG. 2, but also by other methods. For example, as shown in FIG. 3, a screw insertion hole 1b is formed from the back surface 1a of the panel 1, a female screw hole 3a is formed in the flat rib 3, and one piece of the piece angle 10 is welded to the beam 13 or the like. The bolt 16 is inserted through the screw insertion hole 10b formed in the other piece of the piece angle 10 through the washer 14, and the tip of the bolt 16 is further inserted through the screw insertion hole 1b. Is screwed into the female screw hole 3a of the flat rib 3 to attach the lightweight cellular concrete panel 1 to the piece angle 10, and the beam 13 is inserted through the piece angle 10.
And the like, and as shown in FIG. 4, a counterbored hole 1d is formed from the surface 1c of the panel 1,
Further, the plate-shaped rib 3 and screw insertion holes 3b and 1e are formed on the rear surface side of the panel 1 coaxially with the seating hole 1d, and one piece of the piece angle 10 is fixed to the beam 13 or the like by welding or the like. The tip of the bolt 16 fitted in the trench 1d is inserted into the screw insertion hole 3b, 1e, and the tip is formed in another piece of the piece angle 10.
b, a nut 17 is screwed into the tip of the lightweight concrete panel 1 through a washer 14 to attach the lightweight cellular concrete panel 1 to the piece angle 10, and fixed to the structural body such as the beam 13 via the piece angle 10. it can.

In the above embodiment, one lath 2
Is shown embedded in the lightweight cellular concrete panel 1, but it is a matter of course that a lightweight cellular concrete panel in which two or more laths 2 are embedded at appropriate intervals can be applied. When the laths 2 are buried at appropriate intervals, it is preferable to arrange the ribs 3 of each lath 2 so as to be offset from each other so that the strength is more averaged. Further, in the above embodiment, the lath 2 including the three flat ribs 3 is shown, but the number of the ribs 3 is not limited to three. Further, in the above-described embodiment, the lath 2 in which the ribs 3 are arranged on both side ends is adopted, but the lath 2 in which the ribs 3 are located slightly inside from both side ends,
That is, it is a matter of course that a lath 2 having a net portion on both side ends may be used. Further, in the above-described embodiment, the case where the lightweight cellular concrete panel 1 is attached to the structural body such as the beam 13 via the piece angle 10 is shown, but as shown in FIGS. 5 (a) and 5 (b). Needless to say, the lightweight cellular concrete panel 1 can be directly attached to the channel body edge 18a and the wooden body edge 18b by the tapping screw 15.

[0011]

According to the method for mounting a lightweight cellular concrete panel of the present invention, a lath having a flat rib is embedded in a lightweight cellular concrete panel, and a screw for attaching the panel to the rib is utilized by using the rib of the lath. The lightweight cellular concrete panel is attached to a structural frame such as a beam by connecting one end of the panel. Therefore, not only a high strength lightweight cellular concrete panel can be obtained by the ribs, but also an iron plate or the like for connecting screws (bolts) in the lightweight cellular concrete panel is not required, and the production of the lightweight cellular concrete panel is accordingly much troublesome. Cost reduction can be achieved without cost.
