Embodiment

[0055] Example: Combine Figure 1-5 As shown, the components involved in the present invention include prefabricated columns 1 , prefabricated beams 2 , elastic gaskets 3 , and high-strength bolt structures 4 .

[0056] The prefabricated column 1 includes a reinforced concrete prefabricated column 11 and a corbel 12 integrally poured on the side of the reinforced concrete prefabricated column 11. The reinforced concrete prefabricated column 11 is a rectangular reinforced concrete structure, and the size is in accordance with the design requirements of the building structure; the corbel 12 is a wedge-shaped three-dimensional reinforced concrete For the structure, the connection between its lower part and the reinforced concrete prefabricated column 11 is reinforced with a wedge-shaped structure, the width of which is the same as that of the reinforced concrete prefabricated column 11, and the size is in accordance with the design requirements of the building structure.

Abstract

The invention relates to the technical field of a prefabricated assembled concrete structure in civil engineering, and concretely discloses an earthquake-proof assembled concrete beam column connection method. The method comprises the following steps of (1) installing a prefabricated column; (2) installing an elastic gasket; (3) installing a prefabricated beam; (4) fastening screw bolts; (5) performing grouting in reserved holes; and (6) filling mortar into grooves. The connection method has the advantages that the high ductility of prestress bars, the elasticity of the elastic gasket, and thesupport force of screw bolts and a bracket are used for providing good earthquake-proof performance and shear strength for an assembled beam column connection joint.

Description

technical field [0001] The invention relates to the technical field of prefabricated assembled concrete structures in civil engineering, in particular to an assembled concrete beam-column connection method for earthquake resistance. Background technique [0002] At present, the prefabricated building method has many advantages such as short construction period, energy saving and consumption reduction, and low environmental pollution. Among them, how to ensure the performance of the connection between prefabricated components is a key issue restricting the development of prefabricated buildings. At present, the connection methods of prefabricated concrete beams and columns are mainly equivalent cast-in-place connections or prefabricated connections. The equivalent cast-in-place connection is to realize the beam-column connection by pouring concrete in the connection area of ​​the beam-column, or stretching the prestressed tendon in the reserved hole, and then using grout.
