Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for arranging and connecting vertical and horizontal reinforcing bars for building walls.

The scope of application of rounded reinforcing bars to shorten the construction period and labor-saving of reinforcing steel works is increasing, and the scope of application is expanding to both gable structures and civil engineering structures, and there are areas where automation and robotization will move forward in the future.

In particular, reinforcing steel units using threaded reinforcing bars are used in nuclear power plants and LNG tanks. It is being actively studied as a wall for large structures such as bridges.

Conventionally, as part of reinforcing reinforcement prefabrication, vertical and horizontal reinforcements were individually formed into units, and the intersections of the vertical and horizontal reinforcements were fixed with clips called cross reinforcements.

According to this conventional example, since the degree of consolidation with the clip is too strong, it is difficult to rotate and move the reinforcing bar O-axis in the axial direction necessary for joint connection, and it requires a lot of effort, making it difficult to shorten the construction period and save labor. It was not something that could be expected to help.

Especially when using threaded reinforcing bars as reinforcing bars.

Since a threaded coupler is used as a joint for the threaded 7V reinforcing bar, OH2 rotation of the reinforcing bar and movement in and out of the reinforcing bar in the axial direction are unavoidable, and this requires complicated labor.

The present invention was devised in view of the above-mentioned situation, and it creates reinforcing bars by intersecting vertical and horizontal reinforcement, and
When hoisting and erecting, it is possible to prevent "bulk" at the horizontal reinforcement, but rotation of the horizontal reinforcement at the connection joint between the horizontal reinforcement and the existing horizontal reinforcement.

By making it possible to put in and take out the reinforcing bars, the advantages associated with unitization of reinforcing bars can be fully demonstrated, and the construction period can be significantly shortened and labor saved. The horizontal reinforcement with a wide supporting part (the screw pitch of the horizontal reinforcement) is arranged horizontally and vertically, and the horizontal reinforcement is attached to the vertical reinforcement using a tool to create a reinforcing bar unit, and The reinforcing bar unit is fixed to the lifting jig, and then the reinforcing bar unit is hoisted and transported via the hoisting jig and erected at a predetermined position. The horizontal reinforcement of the reinforcing bar unit is then connected to each of the corresponding existing horizontal reinforcement via screw couplers.

Embodiments of the present invention will be described in detail below with reference to the drawings.
