Reinforcing structure and reinforcing method of construction joint in reinforced concrete structure

Abstract

The invention discloses a reinforcing structure and a reinforcing method of a construction joint in a reinforced concrete structure. The reinforced concrete structure comprises an erection reinforcing steel bar, a stirrup and a tensile bar, wherein the tensile bar and the erection reinforcing steel bar are attached to the inner side of the stirrup and bonded with the stirrup, a diagonal bar reinforcing structure comprises at least one diagonal bar penetrating through a vertical plane on which the construction joint is arranged, the bottom and the top of the diagonal bar are respectively welded on the tensile bar which is arranged on the bottom and the erection reinforcing steel bar which is arranged on the top, and an included angle formed between the diagonal bar and the tensile bar is 45 degrees or 60 degrees. The reinforcing structure and reinforcing method of the construction joint in the reinforced concrete structure are safe, reliable and convenient to construct; and the strength and the shearing-resistant carrying capacity of the reinforced concrete structure are improved, and the stability and the safety of the reinforced concrete structure are guaranteed.

Description

technical field [0001] The invention relates to a reinforcement structure and a reinforcement method for construction joints in reinforced concrete structures, belonging to the field of reinforcement of reinforced concrete structures. Background technique [0002] In the process of concrete pouring, due to design requirements or construction needs to be poured in sections, the joint formed between the first and last poured concrete is the construction joint. Construction joints are not real joints, but weak diseased surfaces formed at the joints of successively poured concrete. Their existence will reduce the tensile, shear, cracking, and impermeability properties of concrete specimens. In general, the concrete in a construction section should be poured continuously to ensure the integrity of the concrete structure, but if the pouring area is too large, or in special construction procedures, such as semi-inverted construction methods, construction joints may be formed.
