本発明は取付用の係止具を埋設したＡＬＣ版の製造方法

ねたり、外面塗装に問題があるという欠点があった。ALC plates are widely used as building materials due to their advantages of being lightweight, heat-insulating, and non-combustible.・Since these A L and C plates usually have low strength, it is difficult to attach them directly to structural members, except for thin plates with a thickness of 50 mm or less. Generally, Z-joints are installed on the sides of the ALC plate. A mounting method is used, and a method is used in which a hole is drilled through the ALC plate in the thickness direction and a washer and a bolt are used for mounting. These methods require a considerable amount of time to install, have low workability, and are unreliable.Also, there is a method of installing through metal reinforcing plates, which is expensive and may impair the appearance. However, there was a problem with the exterior coating.

It is necessary that the

、欠陥箇所となり易い問題点もあった。The manufacturing method for ALC plates with embedded locking tools is as follows:
No. 9-38384 discloses that a mounting bracket having an anchor iron plate is supported by reinforcing bars, and Japanese Utility Model Application Publication No. 55-48917 discloses that two anchor steel bars are welded to the side wall of a threaded tube. An ALC panel is shown in which the anchor steel rods are protruded perpendicularly to the main body, and are embedded within the panel body by connecting the anchor steel rods to reinforcing bars of the panel body, and both are fixed to the reinforcing bars by direct welding or other means. AL
C Because the placement precision of reinforcing bars within the manufacturing formwork is not sufficient,
The position of the latching tool for mounting is also not satisfactory, and there are cases where the mount is not properly perpendicular to the plate surface. Furthermore, when a locking tool with an anchor iron plate is fixed to a reinforcing bar and then subjected to rust prevention treatment, there is a problem in that the rust prevention film tends to become thin on the flat surface of the anchor iron plate, which tends to cause defects.

である。In order to achieve this object, the present invention is designed to straddle the parallel main bars of two sets of reinforcing bars arranged along both plate surfaces in the formwork before the plastic material is combed in the ALC plate manufacturing process. Therefore, insert a plastic holding piece, and insert a long nand with an anchor plate inserted into the through hole provided in the holding piece as a fastener for installation, through both ends of the holding piece so that it is perpendicular to the plate surface. Next, a plastic material is poured into the mold, foamed and semi-hardened, cut at the cutting position, cured in an autoclave, and a locking tool for attachment is embedded.
以下本発明方法を図面に従って説明する。The method of the present invention will be explained below with reference to the drawings.

たときに、版面に直角に開いている。1 is the main reinforcing bar placed in the longitudinal direction of the ALC plate among reinforcing bars, 2 is the horizontal bar welded orthogonally to the main reinforcing bar 1, and two sets of lattices are placed near both ALC plates along the plate. The reinforcing reinforcing bars 3as and 3b are maintained at desired intervals by spacers (not shown). Reference numeral 4 denotes a holding piece made of plastic, which has clamping parts 5 at both ends that can be held between parallel main reinforcements, and a through hole 6 for a long nut in the center of the holding piece 4.
is provided, and this through hole 6 opens perpendicularly to the plate surface when the holding piece 4 is clamped to the main reinforcement 1.

い。The two holding pieces 4as and 4b are the two sets of reinforcing bars 3as.
A long nut 9 is clamped at a symmetrical position with respect to the center plane of the thickness of the ALC plate 3b, and a long nut 9 is inserted through the anchor plate 8 as a locking tool 7 for installation and fixed by welding. By inserting and holding both ends into through holes 6 provided in the holding piece 4, the long plate 9 is held so as to be perpendicular to the plate surface. The long napht 9 can be arbitrarily selected to have a circular or hexagonal cross section, and only one of the threads may be cut on the inner surface if necessary.

ことができる。It is necessary to apply anti-rust treatment to the mounting fastener 7 unless both the anchor plate and the long nut are made of stainless steel, in which case it is necessary to take sufficient care to apply a film of anti-rust agent before installation. It is necessary to make sure that the thickness does not become too thin.This installation tool can be easily set manually at the desired location of the reinforcing reinforcing bars that have been pre-assembled with anti-corrosion treatment. .

仮に切断位置に突出しても支障をきたさない。To manufacture the ALC plate of the present invention, reinforcing reinforcing bars with mounting fasteners set at necessary locations are placed in a formwork, and a plastic material such as silica stone, cement, lime, or gypsum and a foaming agent are added in accordance with a conventional method. The slurry is injected and foamed, and when the plastic material is semi-hardened, it is cut into specified dimensions using piano wire, etc., and after curing in an autoclave, the plastic material on the surface of the locking device is removed and used immediately. It can be made possible. Although the holding piece 4 made of plastic ivy melts and virtually disappears at the high temperature during autoclave curing, there is no particular problem in terms of strength when attaching the fasteners for attachment. It is necessary to use a plug made of an appropriate material to prevent the plastic material slurry from entering the long nut of the locking tool, but if you use a plug made of foamed plastic such as styrofoam or foamed urethane, it will prevent the slurry from entering during autoclave curing. This is convenient because it melts and virtually disappears. Also, if this stopper is made of foamed urethane, etc., it can be easily cut with piano wire if it contains water.
Even if it protrudes into the cutting position, it will not cause any trouble.

It was possible to make subtle corrections, the fixture was correctly perpendicular to the plate surface, and the mounting strength was almost satisfactory.
