Problems solved by technology

[0004] For the welding method, although the anti-corrosion oil is applied, the anti-corrosion effect cannot be realized at all due to the friction and silkworm bite of the anti-corrosion oil by the underground earth and stone during the process of sinking into the ground after the butt joint.

Abstract

The invention discloses a precast concrete component butting method and a precast concrete component butting method applying the butting structure. The precast concrete component butting structure comprises a first step of installing an inserting and connecting anchor bar and a joint bar preformed hole at the butting end of a component, and a second step of pre-casting a plurality of embedded parts on the side face of the butting end. In the process of combining and butting, the precast concrete component provided with the joint bar preformed hole is plunged to the ground, epoxy resin mortar is poured into the joint bar preformed hole, the inserting and connecting anchor bar of the precast concrete component is completely inserted into the joint bar preformed hole filled with the epoxy resin mortar. A connecting piece is used for being connected with the embedded parts in a butting mode to enable the component to have a good butting structure. Due to the fact that the environment-friendly and non-toxic epoxy resin mortar serves as an antiseptic adhesive agent, the epoxy resin mortar at the connector position is plunged to the ground to be solidified after the butting is finished, compared with a traditional precast concrete component butting method, the novel precast concrete component butting structure is high in construction speed, and antiseptic property, anti-pulling property and anti-horizontal shear of the precast concrete component at the connector position are improved.

Description

[0001] Involved areas [0002] The invention relates to a butt joint structure of concrete prefabricated components in the field of building construction and a method for butt joint of concrete prefabricated components using the butt joint structure. Background technique [0003] As a building structure component, concrete prefabricated components occupy a large market space in the field of building construction. In foundation construction, such as pile foundation, after two components are butted together, they often have to be sunk into the ground as a foundation, which sinks the joint into the ground. A series of problems such as anti-corrosion, tensile resistance, and horizontal shear resistance at the joint, directly related to the safety of the building. At present, there are two methods of butt jointing of reinforced concrete prefabricated components in relevant standards, namely welding method and anchoring method, for example, "Prefabricated Reinforced Concrete Square...
