[Industrial Application Field] This invention relates to a reinforcement structure for column-beam joints in reinforced concrete buildings. [Prior Art] Conventionally, as a reinforcement structure for column-beam joints in reinforced concrete buildings, as published in Japanese Utility Model Publication No. 7622/1982, reinforcement structures were used to extend across the column and the beams on both sides thereof. (1) An annular fixing section is formed by heating and compression to bulge out of the through main reinforcement to be buried, (2) a brim-shaped anchoring section made of a reinforcing bar piece is fixed to the main through bar by welding, (3)
It is known that a flange-shaped fixing portion made of a tube is fixed to the main threaded reinforcement. However, in the case of (1) above, it is necessary to heat a part of the main through reinforcement using a heating device and a compression device and then compress it using a compression device, which increases equipment costs and requires complicated processing operations. In the case of (2) above, complicated welding work is required, and there is a risk that the main reinforcement will melt during welding, resulting in a cross-sectional defect.Furthermore, in the case of (3) above, it is difficult to weld the thick-walled pipe Since it is difficult to firmly fix the threaded main reinforcing bars during use, there is a problem in that the anti-slip force of the threaded main reinforcing bars is small. [Purpose and structure of the invention] The purpose of this invention is to provide a reinforcement structure for reinforced concrete column-beam joints that can advantageously solve the above-mentioned problems, and the gist of this invention is to: A large number of through main reinforcements 3 that are buried so as to extend across a concrete column 1 and concrete beams 2 that are integrally connected on both sides thereof are anchored with irregularities on the outer peripheral surface at the column-beam joint. A reinforced concrete column-beam joint reinforcement structure is characterized in that a high-strength coating mortar 4 is integrally applied. [Example] Next, this invention will be explained in detail using illustrated examples. Figures 1 to 4 show a first embodiment of this invention, and show through main bars 3 made of deformed reinforcing bars.
A high-strength coating mortar 4 for fixing is integrally applied to the part to be buried in the column-beam joint, and a plurality of concave portions and convex portions are passed through the outer circumferential surface of the high-strength coating mortar 4 alternately in the longitudinal direction of the main reinforcement. formed into,
A through main reinforcement 5 with covering mortar for fixing is configured,
A large number of fixing coated modules configured in this way

According to this invention, a concrete pillar 1 and concrete beams 2 integrally connected on both sides of the pillar 1 are constructed.
High-strength coating mortar 4 for fixing, which has irregularities on the outer peripheral surface at the column-beam joint, is integrally applied to a large number of through main bars 3 that are buried so as to extend over the entire length of the column. A strong high-strength coating mortar 4 for preventing slipping can be integrally provided with the main reinforcement 3, and the high-strength coating mortar 4 has irregularities on the outer peripheral surface, and
Since the material has excellent adhesion to concrete, it is possible to improve the bonding strength between the main through reinforcement 3 and the concrete at the column-beam joint.
