Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for temporarily reinforcing a large reinforced concrete structure after temporarily assembling a column or the like of a large reinforced concrete structure, and a jig for the method.

[0002]

2. Description of the Related Art Hitherto, there has been proposed a method of constructing a reinforcing bar of Japanese Patent Application No. Hei 10-278323 and a jig for temporarily assembling the reinforcing bar used therein.

[0003] In this method, a plurality of columns are mounted on a base frame at a construction site to form a temporary assembly jig, and a reinforcing bar is attached to the columns of the temporary assembly jig using a hook portion, a locking pin, and a fastening clip. The temporary assembly was formed by fixing, and then the temporary assembly jig was removed from the base frame, and a wire rope was hung above each of the columns and transferred to the built-in position, so that the temporarily assembled horizontal streak was joined to the main streak. Thereafter, the hooks, the locking pins, and the fastening clips are removed one by one from each support, and the reinforcing bar of the temporary assembly is released from the temporary assembly jig to remove the temporary assembly jig.

Also, in the hook portion and the locking pin of the support and the support portion, a hole is penetrated through the support, the hook is inserted into the hole, the hook is stopped by the locking pin, and a fastening clip is formed. Hook and hold the rebar together with the struts. In another embodiment, a support piece for supporting a reinforcing bar is directly attached to a support.

[0005]

Conventionally, in a method of temporarily assembling a reinforcing bar using a temporary assembling jig, a plurality of columns are firmly attached to a base frame by bolts on a base frame. When mounting a plurality of columns of the temporary assembly jig to the base frame, it is necessary to rigorously mount the columns so as not to fall down and to stand upright, and the work is troublesome and troublesome.

After the columns are firmly attached to the base frame, a reinforcing bar is fixed to the columns of the temporary assembly jig with hooks, locking pins and fastening clips, and the columns are temporarily assembled. Since the transfer is carried out after being removed from the base frame, the bolt firmly attached to the base frame must be removed each time, which is very troublesome.

[0007] In addition, in each transfer, a wire rope is hung on the upper part of each column, and the balance of each wire rope is adjusted, and then the transfer is performed. He spent so much time working.

Further, during the transfer after being temporarily assembled to the temporary assembling jig and at the time of joining the horizontal streak of the temporary assemblage to the vertical streak,
The hooks and locking pins of the currently used support are often broken, which is concentrated on the rod-shaped hooks and locking pins, and the weight is particularly concentrated if the wire rope is imbalanced. Since the wire rope is hung on the upper part of each support, the central part of the temporary assembly is not lifted, and is deformed in a mortar shape around the central part of the temporary assembly, and an abnormal force is intensively applied. If the hook is changed to a thick one so that the hook and the locking pin do not break, the hole in the support must be enlarged, and the strength of the support will decrease. There are drawbacks.

Further, in the case of the embodiment in which the support piece is directly attached to the support, when the support is pulled upward after the rebar is connected, the support piece may be caught by the rebar and hinder it.

In addition, when connecting the horizontal streaks of the temporary assembly with the vertical streaks and releasing the temporary assembly from the temporary assembly jig, the hook portion of the support portion, the locking pin, and the fastening clip are removed each time. Due to the large amount of removal and its shape, handling of the removed material is very complicated.

[0011] In addition, the conventional hooks, locking pins and fastening clips of the supporting portion are specially designed to simply hold the rebar and, as described above, are to be removed one by one. Sometimes it is not a structure that can be released all at once when holding and releasing, but it takes time and labor, and imbalance of the temporary assembly when removing it occurs.

Further, after the horizontal streaks of the temporary assembly are connected to the vertical streaks, the hook portion of the support portion, the locking pin, and the fastening clip are removed one by one, whereby the temporarily assembled temporary assembly is supported. And the unsupported places will cause the balance of the entire temporary assembly to be lost, resulting in uneven weight, causing breakage of the hooks and locking pins described above. During this time, the temporary assembly jig was greatly shaken, and the temporary assembly could collapse, which was dangerous.

[0013]

According to a first aspect of the present invention, there is provided a method for temporarily assembling a reinforcing bar. And a construction method having a process of transporting the temporarily assembled temporary assembly to the built-in position and a process of connecting the horizontal streaks of the temporarily assembled temporary assembly to the vertical streaks erected at the built-in position.

Thus, the temporary assembly is released from the temporary assembly jig all at once.

In the means for simultaneously releasing the temporary assembly, the temporary assembly can be released in a well-balanced manner so that the temporary assembly is combined with the column reinforcement of the large reinforced concrete structure at a time as a temporary assembly of a predetermined assembly amount. Therefore, it is necessary to release the temporary assembly by means of simultaneous release by the support receiving fitting and the holding metal fitting, so that the temporary assembly is quickly released without balancing.
