Prefabricated building structure

Abstract

The invention provides a prefabricated building structure. The prefabricated building structure comprises a hollow part, a solid part and a first cage body, wherein the hollow part is connected with the solid part; a core groove is formed in the hollow part; the first cage body is arranged in the solid part and the hollow part; the prefabricated building structure further comprises a pre-embeddedconnecting piece; and the pre-embedded connecting piece is connected to the end part of the first cage body in the axial direction. The prefabricated building structure comprises the solid part and the hollow part, and a second cage body is arranged in the solid part so that the local reinforcement ratio at the solid part can be improved, therefore, the consumption of raw materials and the weightof the prefabricated building structure are reduced, the manufacturing cost is saved, the longitudinal bearing capacity and the shearing force resistance are not reduced but improved due to the arrangement of the second cage body, and the tensile capacity, compressive capacity and anti-seismic capacity of the prefabricated building structure are improved.

Description

technical field [0001] The invention relates to the technical field of buildings, 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 produced in factories, and then transported to the construction site for use. Existing prefabricated building structures are mostly solid or hollow structures, but 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 mechanical strength cannot be guaranteed. Therefore, there is a need for an improved prefabricated building structure, which can not only reduce weight and save raw materials, but also ensure its mechanical strength. Contents of the invention [0003] In view of this, it is necessary to provide an i...
