Preparation method of prefabricated part

Abstract

The invention relates to a building construction method, and in particular, discloses a preparation method of a prefabricated part. The prefabricated part is provided with an embedded connecting piece; and the preparation method comprises the steps of: (1) support arrangement of a mold; (2) pavement of an embedded reinforcement net frame; (3) fixed connection between the mold and the embedded connecting piece; (4) binding fixation between the embedded reinforcement net frame and the embedded connecting piece; (5) molding by pouring; and (6) demolding. In the actuation process, multiple parts of the embedded connecting piece are fixed to form multiple points and one surface; and when one end of the embedded connecting piece is connected with a template, the difficult dismounting of a fastening piece in the later period caused by floating, twisting and deviation of the embedded connecting piece in the concrete pouring or vibration molding process is generated, and the phenomenon of butt joint of the embedded connecting piece but difficult connection in the splicing process of the prefabricated part is generated. The preparation method can effectively improve the production quality of the prefabricated part and the construction efficiency in the assembly process of the prefabricated part.

Description

technical field [0001] The invention relates to a building construction method, in particular to a method for preparing a prefabricated part. Background technique [0002] In the field of prefabricated building construction, the construction speed and precision of on-site assembly of prefabricated parts has become an important key technology for prefabricated concrete structures, which directly determines the quality and construction efficiency of the entire project. At present, the connection and assembly of prefabricated parts is mainly connected by pre-embedded connectors. However, due to various deviations in the production process of pre-fabricated parts, during the assembly construction process, the problem that the embedded connectors cannot be connected often occurs. This often requires construction personnel to make corrections, or the prefabricated parts cannot be used normally, which not only leads to slow construction speed, increases production costs, and even a...

Problems solved by technology

At present, the connection and assembly of prefabricated parts is mainly connected by pre-embedded connectors. However, due to various deviations in the production process of pre-fabricated parts, during the assembly construction process, the problem that the embedded connectors cannot be connected often occurs. This often requires construction personnel to make corrections, or prefabricated parts cannot be used normally, which not only leads to slow construction speed, increases production costs, and even affects building quality

[0003] The problem that the pre-embedded connectors cannot be connected is that on the one hand, the positioning of the pre-embedded connectors is not accurate due to the operator's operation error in the production process of the pre-embedded parts; During the process, there is relative movement with the template, which leads to inaccurate positioning

In the preparation process of prefabricated parts, the positioning and fixing of the embedded connectors are usually only carried out by binding the embedded connectors with the steel grid. The frame and the formwork did not form a reliable connection, resulting in relative movement between the embedded connector and the formwork during the vibration forming process of the prefabricated part. On the one hand, it leads to inaccurate positioning of the embedded connectors, on the other hand, it affects the production quality of the prefabricated parts, and the deviation caused by the vibration forming process will seriously affect the butt joint of the prefabricated parts
