Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for joining columns and beams of a rigid frame brace.

In the conventional rigid frame prefabricated column and beam connection, as shown in Figures 1 and 2, a beam support jaw (2) is provided at the top of the PC column (1), and the PC beam is attached on top of the jaw (2). (3) was set, and a joint concrete IJ-) (4i) was cast in the space formed between the columns and beams at the column head.

Therefore, from a design point of view, it is impossible to construct a joint in which the jaw (2) interferes with the construction, and a cock (5) is provided on the end face of the PC beam (3) to resist shearing force.

In the figure, (6) is the column main reinforcement, (7) is the shear reinforcement, and (8)
is the beam top reinforcement, and (9) is the cost reinforcement.

The present invention has been proposed in order to eliminate such drawbacks, and includes a PC beam in which the upper part of the beam end face is cut out, and the lower end protrusion in contact with the cut face is mounted on the column head of the PC column, This invention relates to a method for joining prefabricated rigid frame columns and beams, which is characterized by placing joining concrete in the space formed between the PC beams and columns at the heads of the PC columns.

In the present invention, as described above, the upper end surface of the PC beam is cut out, and the lower end protrusion in contact with the cut surface is used to mount the protrusion on the column head of the PC column. , the PC column and the beam are joined by pouring joint concrete into the space formed between the beams. Therefore, according to the present invention, the PG beam support has a jaw for use at the capital of the PC column. Furthermore, due to the presence of the missing plane at the end of the PC beam, even if the PC beam is set in a position where it contacts the main reinforcement of the PC column, reinforcement work for shear reinforcement within the column-beam joint can be easily performed. It will be done. In addition, since the lower end protrusion connected to the cutout surface at the end of the PC beam also serves as a cock, the present invention has many advantages, such as eliminating the need to provide a cock on the end face of the PC beam as in the conventional case. It is something that you have.

The present invention will be described below with reference to the illustrated embodiments.

(A) shows a PC beam, in which a cutout surface 0υ is provided at the upper part of the end face, and the end of the beam lower end main reinforcement (t3) is provided to protrude from the lower end protrusion a2 that touches the cutout surface (111). (1
L-shaped reinforcing hardware I is anchored at both ends of the 2+.

Note that the upper end surface of the PC beam (A) is cut out approximately equal to the thickness of the slab, and the upper ends of the ribs (151) protrude above the cutout.

Then, the lower end protrusion a2 of the PC beam is set on the column head of the PC column (B) from which the column main reinforcement ae projects, in the overlapping part of the column main reinforcement αe, and the PC column (A) (B) at the same column head is set. Shear reinforcing bars Q7) are arranged within the joint space formed between them. At this time, due to the existence of the cut surface 0υ of the PC beam,
PC column (PC beam (
Even if N is set, the shear reinforcement within the joint is 0.
7) Reinforcement work is easily performed.

In addition, the reinforcing hardware θ4) of the PC beam (A) is replaced with the PC column (B).
This is to ensure safety during temporary construction by welding to metal fittings buried in the capital of the pillar.

Furthermore, the ribs of the PC beam (A) (one top end protrusion and the upper part of the column-beam joint space are passed through the beam upper end main bar cod), and the reinforcement is placed in the column-beam joint space and the top of the PC beam (A). IJ-to 01
and (A), and the PC floorboards (not shown) whose ends are mounted on the PC columns and beams (A) are joined together.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various ways without departing from the spirit of the present invention. .
