Description

[Detailed Description of the Invention] The present invention relates to a joint structure between a column and a wall.

When connecting a prefabricated wall (hereinafter referred to as a PC wall) to a steel column that has conventional main reinforcement and spiral reinforcement around its outer periphery, anchor reinforcement, such as dowel reinforcement with hooks, is installed on the end face facing the column to connect the column. is embedded in advance, and when the PC wall and column are erected, the hook at the tip of the anchor bar is connected to the column. However, according to this PC wall,
After installing the PC wall in a predetermined position, when placing the spiral reinforcement that is bundled with wires at multiple points on the column and dropping it along the outside of the main reinforcement, the hook of the anchor reinforcement will already be reflected in the falling trajectory of the spiral reinforcement. Since it is located in the inner part of the wall, it interferes with the fall of the spiral muscle, making it difficult to arrange the spiral muscle. For this reason,
Conventionally, it was necessary to arrange the main reinforcement for steel columns, then the spiral reinforcement first, then install the PC wall and connect the anchor reinforcement to the column, which delayed the installation of the PC wall and made the work more efficient. I couldn't do it properly.

The purpose of the present invention is to provide a column-to-wall joint structure that allows PC walls to be incorporated regardless of column reinforcement, thereby improving work efficiency.

Embodiments of the present invention will be described below based on the drawings. In Figures 1 and 2, a plurality of (four in the drawings) main reinforcements 3, ... are arranged around the steel frame 2 of a column 1, and spiral reinforcements 4 are further wrapped around these main reinforcements. A PC wall board 5 is installed on the side of the building. 5a is a beam installed on this PC wall.

In this example, on the end face of the PC wall plate 5 facing the pillar 1, cotters 5b are provided at equal intervals. PC wall board 5 on the pillar 1 side from each cottage 5b...
A turn part of the wall reinforcement 6 arranged in this direction protrudes, and this turn part becomes a connecting part 6a of the anchor reinforcement. A clip-shaped anchor bar 7 as shown in FIG. 3, for example, is engaged with the connecting portion 6a, and the anchor bar is supported by being inserted between the spiral bars 4, 4 of the column 1. In addition, the anchor bar 7 rotates in the horizontal direction as shown by the imaginary line in FIG. 2, and the spiral bar 4
You can get out.

Next, a method of connecting the PC wall plate 5 and the pillar 1 will be explained. First, the PC wall board 5 is erected so that the end surface of the wall board corresponds to the side of the pillar 1 that was erected earlier. At this time, the anchor reinforcement 7 is laid down as shown by the imaginary line in FIG. Next, main reinforcements 3 are arranged around the outer periphery of the steel frame 2 of the column 1, and spiral reinforcements 4 are dropped from the upper end of the main reinforcements using the main reinforcements as a guide. Finally, rotate the anchor bar 7 and insert it into the spiral bar 4 as shown by the solid line.
Finish the work with support in between. After that, formwork is framed outside the main reinforcements 3, and concrete is poured.

As described above, according to the present invention, it is possible to erect a PC wall regardless of the reinforcement arrangement of the columns, and it is also possible to connect the walls with the columns. This has the effect of greatly improving the efficiency of PC wall erection work. Also, as a means of supporting the tip of the anchor bar,
Since spiral reinforcement is used as a reinforcing element for columns, there is no need for specially processed support members, which reduces the number of parts and simplifies the structure. During the connection work, the distal ends of the anchor reinforcements can be placed between the helices of the spiral reinforcements and held between them, and the work is simplified because the trouble of special winding and welding can be omitted.
