Problems solved by technology

This connection method has the following problems: at present, in order to meet the force requirements of the joint between the steel bar and the sleeve, the sleeve needs to be strengthened or specially designed, and the structure is complicated; the opening of the sleeve is at the bottom of the prefabricated component, and it is difficult for the operator to grasp the bottom when connecting. The relative position of the exposed steel bars of the component and the sleeve opening of the upper component usually requires auxiliary tools or the operator to observe in a kneeling posture, which is low in efficiency and will damage the health of the operator in the long run; multiple preparations for the grouting operation are required, including grouting Separate allocation of materials, grouting partitions, etc., and when grouting a grouting unit within the specified time, it is not allowed to grout from multiple grouting ports at the same time. This process is cumbersome, long working time, high precision requirements and low error tolerance.

Abstract

The invention relates to an assembly type prefabricated part connecting structure and a construction method. The connecting structure comprises a plurality of anchoring devices embedded in the bottom of an upper prefabricated part and a plurality of exposed screws vertically embedded in the top of a lower prefabricated part. The anchoring device comprises a horizontally-arranged anchoring plate, a connecting plate vertically fixed to the anchoring plate and a steel bar vertically fixed to the upper portion of the connecting plate, reserved openings are formed in the center of the plate face of the anchoring plate, a plurality of screws and a plurality of reserved openings are consistent in position distribution and can be connected in an inserted mode in a matched mode, and each screw is provided with a nut and a gasket. The construction method comprises the steps that the main body frame of the prefabricated parts is built on the basis of the anchoring devices, the screws with the number equal to that of the anchoring devices are fixed to the top end of the main body frame, pouring is conducted, and the prefabricated parts are assembled by connecting the anchoring devices of the upper prefabricated parts with the screws of the lower prefabricated parts. The simple, efficient, stable and reliable prefabricated part assembling process is achieved.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to an assembled prefabricated component connection structure and a construction method. Background technique [0002] In recent years, the development of prefabricated buildings has gradually matured. Unlike traditional on-site pouring methods, prefabricated buildings are pre-processed and produced uniform standard components and accessories in the factory, and then transported to the construction site for assembly and installation through reliable connections. The operation form has high construction efficiency, high quality precision, energy saving and environmental protection, and low cost. In the assembly process, the commonly used connection method is the sleeve grouting connection. The principle is to embed the sleeve into the connection end of the component in advance when making the prefabricated component, and then insert the exposed steel bar of anoth...
