L-shaped concrete prefabricated part

Abstract

The invention belongs to the technical field of prefabricated parts and in particular discloses an L-shaped concrete prefabricated part which comprises an L-shaped shell, a connecting sleeve, a sealing module, a shaking module and an expansion column, wherein the sealing module is arranged inside the vertical section of the L-shaped shell; the expansion column is arranged inside the horizontal section of the L-shaped shell; a water absorption resin coating is arranged on the outer side of the expansion column; the outer side of one end of the vertical section of the L-shaped shell is sleeved by a connecting sleeve; a feeding hole is formed in one end of the vertical section of the L-shaped shell; two sealing bolts are connected with both sides of the feeding hole in t he L-shaped shell ina spiral embedding manner; a first cavity is formed in the inner walls of inner walls on both sides of the vertical section of the L-shaped shell; a rotating rod is rotationally connected with the inner side of the first cavity through a torsional spring; a rubber plug is fixedly connected with the top end of the rotating rod; the sealing module comprises a spherical surface, a thread connecting rack, a first water absorption resin block, a second water absorption resin block and a connecting column. By adopting the L-shaped concrete prefabricated part, concrete can be distributed uniformly, and in addition, the strength of the prefabricated part can be improved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated parts, in particular to an L-shaped concrete prefabricated part. Background technique [0002] In recent years, PC prefabricated buildings have developed rapidly in my country. It can not only change the shortcomings of traditional construction sites, such as many workers, heavy workload, difficult quality assurance, and large waste of resources, but also one of the important directions for the overall transformation of my country's construction industry. very important. However, the design and research of precast concrete components is still in the preliminary stage, especially the connection method between components is not reasonable enough, the connection between components is not convenient, and the prefabricated parts are easily misplaced when splicing, which brings unnecessary troubles to the site construction. [0003] Although the standardization of the size and characteristics of p...

Problems solved by technology

However, misalignment is easy to occur when prefabricated parts are connected. Therefore, an L-shaped concrete prefabricated part is proposed, which can make the concrete distribution uniform, improve the strength of the prefabricated part, and facilitate the connection between prefabricated parts.
