Description

The present invention relates to a reinforcing bar or anchor bolt fixing template in which a reinforcing bar or anchor bolt fixing tool used to fix a reinforcing bar or anchor bolt to be assembled is attached to a template when building a building made of reinforced concrete.

  In building a building made of reinforced concrete, in order to fix the assembled reinforcing bars or anchor bolts, conventionally, holes for reinforcing bars or anchor bolts have been drilled in a plywood board, etc., and the heads of the reinforcing bars or anchor bolts are inserted. It was fixed. However, this method has problems such as breakage of the veneer plate and inability to repeatedly use it.

Claim 1 of Patent Document 1 states that “ a screw having a cross-sectional shape composed of two substantially parallel flat portions and two circular arc portions facing each other in the outer shape of a screw formed between the ends of both flat portions. Each of the plurality of mounting holes is a template that is fixed to the left and right shaft portions of the anchor bolt formed by the reinforcing bar with nuts and has a plurality of mounting holes through which the left and right shaft portions are respectively inserted. The anchor bolt template is characterized in that a wall portion having an inner wall surface substantially coinciding with the inner wall surface of the mounting hole is erected at a location corresponding to the screw. When inserted into the hole 3, the wall prevents the template from falling into the thread groove of the shaft portion, and is parallel to the flat portion between each shaft portion and each mounting hole, that is, in the front-rear direction of the anchor bolt. It is disclosed that there is no play.

Further, claim 1 of Patent Document 2 states that “ a cross-sectional shape composed of two substantially parallel flat portions and two circular arc portions facing each other in the outer shape of a screw formed between end portions of both flat portions. An anchor bolt template used for an anchor bolt formed by a threaded reinforcing bar having a plurality of attachment holes through which the anchor bolt is inserted, and each of the plurality of attachment holes is substantially the same as a cross-sectional shape of the anchor bolt. In the anchor bolt template, characterized in that the long holes have the same shape. “When each shaft portion is inserted into each mounting hole 3, a gap is created between each shaft portion and each mounting hole. However, there is no backlash in the direction perpendicular to the flat portion of each shaft portion between them.

As described above, the conventional anchor bolt template is made of a wooden board or a plywood board, but cannot be reused because it is severely damaged. In order to improve such a point, Patent Documents 1 and 2 disclose anchor bolt templates in which holes for anchor bolts are formed in a metal plate. The anchor bolt template disclosed herein has a structure in which the anchor bolt hole of the anchor bolt template cannot have a gap between each shaft portion and each mounting hole, and the template further includes the shaft portion. It has a structure that is prevented by the wall portion from falling into the screw groove. In this structure, when the anchor bolt is distorted, it must be corrected one by one so that it fits into the anchor bolt hole of the anchor bolt template. Further, there is a drawback that the anchor bolt cannot be used if the thickness is different.
Therefore, a reusable reinforcing bar or anchor bolt fixing tool that can be used regardless of the thickness of the reinforcing bar or anchor bolt, and a reinforcing bar or anchor plate fixing template with the fixing tool attached to the template. Was desired.
