Prefabricated building structure

Abstract

The invention relates to a prefabricated building structure which comprises a pile body, a pile tip, an embedded connecting piece and a detachable connecting piece. The pile body is detachably connected with the pile tip, the embedded connecting piece is arranged at the end of the pile body, a first through hole is formed in the pile tip, the first through hole is aligned with the embedded connecting piece, and the detachable connecting piece is connected with the embedded connecting piece through the first through hole; and a first cage body and an embedded pipe are arranged in the pile body,the embedded pipe is arranged in the middle of the pile body, the embedded pipe is hollow, and the embedded pipe is arranged around the first cage body. Compared with an existing structure, the prefabricated building structure has the advantages that raw material consumption is reduced, and cost is reduced; the bearing capacity is improved, and the service life is prolonged; and the reliability of the prefabricated building structure in service is ensured. Besides, the pile tip can increase the capability of the prefabricated building structure to penetrate through a soil layer during sinkingconstruction, a guiding effect is achieved, and the breakage probability of the prefabricated building structure is reduced; the pile tip is detachably connected with the pile body, so that constructors can conveniently manufacture the pile tip in advance and then connect the pile body with the pile tip, the prefabricated building structure is more flexible, and requirements of different workingconditions can be met.

Description

technical field [0001] The present invention relates to the field of construction technology, in particular to a prefabricated building structure. Background technique [0002] In the field of construction technology, in order to facilitate production and processing and reduce construction time, prefabricated building structures are usually fabricated in factories, and then transported to construction sites for use. The existing prefabricated building structures are mostly solid or hollow structures, but the solid structures have problems such as excessive weight, difficulty in transportation, and waste of raw materials. On the other hand, although hollow structures can save raw materials, their seismic mechanical properties and durability cannot be guaranteed. In addition, in the process of subsidence construction, the integrally formed pile body and pile tip cannot meet the construction needs under different geological soil conditions, resulting in the inability of the pil...

AI Technical Summary

Problems solved by technology

Most of the existing prefabricated building structures are solid structures or hollow structures, but the solid structures have problems such as excessive weight, difficulty in transportation, and waste of raw materials; on the other hand, although the hollow structures can save raw materials, their seismic performance and durability cannot be guaranteed ; In addition, during the subsidence construction process, the integrated pile body and pile tip cannot adapt to the construction needs of different geological soil conditions, resulting in the pile tip not being able to quickly penetrate the soil layer
