Description of the Related Art Conventionally, as a method for joining columns and beams made of reinforced concrete of this type, an end of a beam main bar is bent into an L-shape or a U-shape and inserted into a space surrounded by a plurality of column main bars. A method of joining a reinforced concrete beam to a reinforced concrete column by fixing the reinforced concrete beam to the reinforced concrete column has been widely adopted. Also disclosed is a method in which a fixing member is screwed into a male screw portion formed at an end portion of a beam main reinforcing bar, disposed on a column main reinforcing bar portion, and fixed to join the joints (Japanese Unexamined Patent Publication No. 6-5795).

面もあった。In the former prior art, however, it is necessary to increase the fixing length of the bent portion of the main beam of the beam in order to secure the fixing force. Reinforcement work in the work was troublesome and there was a problem in workability. On the other hand, in the latter prior art, the beam main reinforcement is arranged in the column main reinforcement in a straight line state and is joined by the fixing force of the fixing member fixed to the end thereof, so that the reinforcing work is easily performed. Although the workability was excellent, it was necessary to enlarge the cross section of the pillar in order to secure sufficient fixing power. Therefore, there has been a surface that has not been adapted to the tendency to reduce the cross sections of columns and beams in order to increase the height and increase the living space in recent years.

Another object of the present invention is to provide a joint method between a reinforced concrete column and a beam, which improves the strength and rigidity of a column-beam joint and is suitable for the tendency of reducing the cross section of the column or the beam.

ことができる。According to the present invention, in order to solve the above-mentioned problems, an end of a beam main reinforcement is inserted in a linear state into a space surrounded by a plurality of column main reinforcements, and the end or the same is inserted. The reinforced concrete beam is joined to the reinforced concrete column via the fixing force of the fixing member fixed to the vicinity of the end, and a reinforcing member is disposed near the fixing member fixed to the main beam of the beam, and a reinforcing member is provided. The technical means of reinforcing the fixing power was adopted. In this case, it is more effective to dispose the reinforcing member above and below the fixing member fixed to the beam main reinforcement so as to reinforce the fixing force of the fixing member from above and below. More specifically, a loop-shaped reinforcing bar is used as the reinforcing member, and the reinforcing member is arranged near the fixing member. Similarly, a loop-shaped reinforcing bar is used to form a column main bar near the fixing member. The applied hoop streak is wrapped around from the outside, and is disposed in the vertical direction so as to intersect each other in the vicinity of the upper and lower sides of the identification attaching member. It can be disposed near the fixing member in a state where the main pillar is inserted through the hole.

ことができる。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention can be applied to a wide range of joints between a reinforced concrete column and a beam made of reinforced concrete in a base portion or a frame portion, and the technical basis is as follows. In order to improve the fixing force of the fixing member fixed to the end portion or the vicinity of the end portion of the beam main reinforcement, that is, in order to improve the pull-out resistance based on the shear strength of concrete, in the vicinity of the fixing member, that is, in the beam direction with the fixing member at the apex. The reinforcement member is disposed in a region crossing the shear fracture surface formed of a conical surface having a vertex angle of approximately 90 degrees to enhance the anchoring force at the joint of the beam main reinforcement with the column. . Therefore, as the shape of the fixing member itself, any shape can be used as long as a predetermined fixing force can be secured by the pull-out resistance based on the shear strength of the concrete, and a plate-shaped or an abacus-shaped swelling swelling back and forth can be used. A member or the like can be used. In addition, the fixing member may be installed at a position where the shear fracture surface of the fixing member can be effectively formed at the joint with the column, and specifically, at the end of the beam main bar or in the vicinity thereof. Will be fixed.
When fixing the fixing member to each of the plurality of main beams of the beam, the fixing positions of the fixing members may be shifted and staggered. In addition, a deformed reinforcing bar or the like is used as a beam main reinforcing bar. By using a threaded rebar as the main beam of the beam, or by forming a male screw near the end of the beam, screwing it through a female screw formed on the fixing member itself, or holding the fixing member between fixing nuts Thereby, it can be fixed at an appropriate position.

It can be appropriately selected in consideration of the arrangement of reinforcing bars on the column side, and can be disposed on one side near the fixing member or on both sides. In short, it is only necessary that the reinforcing member provided near the fixing member can enhance the fixing power based on the identified attaching member. Regarding the configuration of the reinforcing member itself, it is possible to use an appropriate reinforcing member such as a loop-shaped reinforcing bar or a plate-shaped reinforcing plate having an insertion hole for a column main bar. When using loop reinforcement,
It is not necessary to combine with the hoop muscles provided on the column main bar side,
You may arrange | position in the state couple | bonded partially. Further, it may be formed in a loop shape in advance, or may be formed in a loop shape in the process of arranging the bars, and the shape may be an appropriate shape such as a rectangle or a circle. As a connecting means at both ends for forming a loop, welding, binding means, or the like can be used. When a plate-shaped reinforcing plate is used, the reinforcing member is disposed near the fixing member in a state where the main bars of the columns are inserted into the insertion holes.
In that case, all the column main reinforcements may be configured to be inserted and supported using one reinforcing plate, or may be configured to be inserted and supported using a plurality of reinforcing plates.

The method of joining the reinforced concrete beam to the reinforced concrete column through the anchoring force of the anchoring member is adopted, so that the workability of the rebar arrangement work is significantly improved as compared with the conventional L-shaped anchoring method and the like, and the beam is further improved. Since a method of arranging a reinforcing member in the vicinity of the fixing member fixed to the main bar and reinforcing the fixing force of the fixing member is employed, the strength and rigidity of the beam-column joint can be improved by a simple operation. In addition, it is possible to obtain an effect that it is possible to easily cope with a tendency of reducing the cross section of the column or the beam.
