Description

Description: FIELD OF THE INVENTION The present invention relates to a method of joining a column and a beam of a structure and a structure thereof, and particularly to a column and a beam suitable for use in a structure having a rigid frame structure. And its structure.

[Prior Art] Conventionally, when a structure is generally constructed, a pillar and a beam form are constructed by a concrete form and a reinforced cage, and concrete is cast into these forms. . However, considering the labor situation of today's construction sites where there is a serious shortage of skilled workers such as formwork and reinforcement, these methods tend to be expensive and difficult to save labor. It is necessary to develop a construction method that eliminates necessary work as much as possible and dramatically improves the construction period and cost. Thus, to date, columns having a precast concrete portion (hereinafter referred to as half-PC columns) and beams partially having precast concrete portions (hereinafter referred to as half-PC beams) have been used. Various column and beam joining structures and construction methods as shown in FIG. 23 are provided.

First, the joint structure A between the column and the beam shown in FIG. 21 is provided on one end of the beam 2 on the upper surface 1a of the column 1 formed in the column construction part of the structure.
This is a structure where 2a is placed and fixed. The beam 2 is composed of a half PC beam and has a beam bar 3 protruding outward from one end surface 2b in the longitudinal direction, and the tip of the beam bar 3 is bent upward in an L-shape. Have been. Also, on the upper surface 2c of the beam 2,
A plurality of U-shaped stirrups 4 serving as shear reinforcing bars of the beam 2 are provided at equal intervals, and these stirrups 4, 4,.
The upper end muscle 5 is disposed so as to be orthogonal to the direction.

In order to join the column 1 and the beam 2, one end 2 a of the beam 2 is placed on the upper surface 1 a of the column 1, and the beam 3 of the beam 2 is placed in the column main bar 6 of the column 1. Then, the connection part 7 of the pillar 1 and the beam 2
The column 1 and the beam 2 are joined by placing concrete in the space.

The joint structure B between the column and the beam shown in FIG. 22 has substantially the same configuration as the joint structure A between the column and the beam, except that a U-shaped cross section 11 is formed at one end 2a of the beam 2. Different in that. Then, to join the column 1 and the beam 2, the beams 2 and 2 are placed on the upper surface 1a of the column 1.
After placing one end 2a of each beam 2 and supporting these beams 2 and 2 with the temporary support 12, respectively,
Arrange a new beam reinforcement 13 so as to extend to the V-shaped section 11,
In this state, the column 1 and the beam 2 are joined by placing concrete in the connection portion 14 between the column 1 and the beam 2.

Further, the joint structure C between the column and the beam shown in FIG. 23 is different from the above-described structure in that a plurality of insertion holes 17 for inserting the column main reinforcement 6 into the beam 2 are formed so as to penetrate vertically. .
Then, in order to join the column 1 and the beam 2, the beam 2 is
, And the column main bar 6 is inserted into the insertion hole 17 of the beam 2, and the beam 2 is moved vertically downward along the column main bar 6, and
The column 1 and the beam 2 are joined by placing and fixing the beam 2 on the upper surface 1a of the column.

These construction methods have advantages of both short construction period and low cost, and are suitable for constructing large-scale stores, offices, factories, and the like.

[Problems to be Solved by the Invention] However, the joint structure between the column and the beam has various problems as described below.

First, in the joint structure A between the column and the beam, since the column main reinforcement 6 and the beam reinforcement 3 collide at the joint of the column 1 and the beam 2 at the same level and the reinforcement cannot be lined up, the reinforcement of these reinforcements is poor and the fixing length is poor. There was a problem that it could not be removed.

In addition, in the joint structure B between the column and the beam, when the beam 2 is supported at a predetermined position, at least the two ends 2a and 2a of the beam 2
Since a total of two temporary supports 12 and 12 are required for each one, the number of temporary materials was increased. Also,
The U-shaped cross section 11 is provided at both ends 2a, 2a (or one end 2a) of the beam 2.
Since it is necessary to form the beam in a), there is a problem that the work of forming the beam is complicated and the workability is not good.

Further, in the joint structure C between the column and the beam, there are problems that it is difficult to form the beam 2 in a direction orthogonal to each other, and that the joining method of the lower end bar 18 is limited to the KEN method or the NKE method.

As described above, at present, workability improvement, workability improvement,
