Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for attaching an ALC plate to a building frame, and more particularly to a locking device for an ALC plate embedded in a large-sized ALC plate manufactured by flat stamping. It is.

[0002]

2. Description of the Related Art Conventionally, a lightweight aerated concrete panel (hereinafter referred to as ALC) in which a fastener for attaching to a frame of a building is embedded.
Various types of locking tools have been proposed. For these fasteners, a nut is welded in advance to a mounting member such as a plate, an angle, or a channel, and the fastener is welded to a reinforcing steel mat, or the nut is directly welded to a reinforcing steel mat. And a reinforcing bar inserted through a through hole of the nut.

Therefore, when attaching these fasteners to a reinforcing bar mat, it is necessary for an operator to weld one by one to a predetermined location, which is troublesome and time-consuming. Also, in the so-called flat beating method in which the raw material mat of the ALC is poured after the reinforcing mat is set horizontally on the mold, depending on the shape and the mounting direction of the nut mounting member, when the raw material slurry foams, turbulence of bubbles is generated. There is a problem that causes the position accuracy to be deteriorated by pushing up the reinforcing bar mat.

[0004]

SUMMARY OF THE INVENTION The present invention is to provide a locking tool which does not cause the above-mentioned problem and can automate the welding operation of the reinforcing bar and the plate.

[0005]

The locking device of the present invention has a long nut with a flange and ribs provided at both ends in the width direction of the rectangular plate, and the plate surface is slightly larger than the outer diameter of the nut. And a plate in which a plurality of large through holes are drilled in parallel.

[0006]

[Function] When the reinforcing bar mat is automatically welded, the ribs on the plate are automatically welded to the desired position on the reinforcing bar, and then the nut is inserted into the through hole at the desired position and the flange is spot-welded. Is done. Further, since a plurality of through holes are formed in the plate in parallel, the position and number of the nuts can be freely set. Furthermore, since the resistance of the horizontal portion is small, when the raw material slurry is foamed, there is no generation of turbulence of the foam or pushing up of the reinforcing bar mat, thereby deteriorating the positional accuracy of the reinforcing bar.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of the locking device of the present invention, and FIGS. 2 and 3 are a perspective view and a front view of a main part showing a state in which the locking device of the present invention is attached to a reinforcing bar mat, respectively. As shown in FIGS. 1 (a) and 1 (b), the locking device 1 of the present invention has a long nut 2 having a flange 2a provided at a base portion thereof, and ribs 3 at both ends in the width direction of a rectangular plate.
The plate 3 is provided with a plurality of through-holes 3b slightly larger than the outer diameter of the nut 2 on the plate surface.

[0008] When attaching the locking tool 1 to the reinforcing bar mat 4, the main bar 4a and the horizontal bar 4b of the reinforcing bar mat 4 are welded by an automatic welding machine (not shown). Then, the plate 3 is supplied so as to straddle two parallel main reinforcing bars 4a at desired positions (four corners in FIG. 2) of the net-shaped reinforcing bar mat 4, and the ribs 3a on both sides are automatically attached to the main reinforcing bars 4a as shown in FIG. After welding, the joint line 4c is welded, and finally, the nut 2 is inserted into the through hole 3b of the plate 3 to spot weld the flange 2a.

[0009]

As described in detail above, the locking device of the present invention has a flanged nut and ribs provided at both ends in the width direction of the rectangular plate, and the plate surface has a larger diameter than the outer diameter of the nut. It consists of a plate in which a plurality of slightly larger through-holes are perforated in parallel, and when attaching to a reinforcing bar mat, the plate ribs are automatically welded to the desired position of the reinforcing bar, and then the desired position of the through-hole And the flange is spot-welded to the plate by inserting a nut into the plate, so that the number of mounting steps is simplified. Further, since a plurality of through holes are formed in the plate in parallel, the position and number of the nuts can be freely set. Furthermore, since the resistance in the vertical direction is small, when the raw material slurry foams, there is no generation of turbulence in the foam and no deterioration of the positional accuracy due to pushing up the reinforced mat.
