Prefabricated building frame and rapid connecting method thereof

Abstract

The invention provides a prefabricated building frame and a rapid connecting method thereof. The building frame comprises at least four sets of supporting column bodies; connecting steel plates are connected with the middles of the supporting column bodies in a penetrating mode; supporting corners are fixedly connected with the side end faces of the connecting steel plates; each supporting cornercomprises a supporting leg body, a connecting platform, a limiting groove and a second threaded hole; the connecting platforms are fixedly connected with one sides of the side end faces of the supporting leg bodies; the limiting grooves are formed in the middles of the connecting platforms; the second threaded holes are formed in the upper end faces of the connecting platforms; a bearing cross beam is fixedly connected between the supporting corners; the bearing cross beam comprises a bearing cross beam body, bolt grooves, a first threaded hole, a limiting column, and a hanging ring; and the bolt grooves are formed in the four corners of the upper end face of bearing cross beam body. The prefabricated building frame is simple to build, stable in structure, high in structural strength and applicable to quick building of lower-layer building frames by the aid of prefabricated building principles.

Description

technical field [0001] The invention relates to the construction field, in particular to an assembled building frame and a quick connection method thereof. Background technique [0002] With the development of modern industrial technology, building houses can be manufactured in batches and in sets like machine production. Just transport the prefabricated building components to the construction site and assemble them. [0003] Assembled architecture began to arouse people's interest in the beginning of the 20th century, and finally realized to the sixties. Britain, France, the Soviet Union and other countries first made attempts. Because the construction speed of prefabricated building is fast, and production cost is relatively low, it is promoted all over the world rapidly. [0004] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such...

Problems solved by technology

[0007] However, the existing building frame needs to build steel wire cages before concrete pouring. The operation process is more complicated, time-consuming and labor-intensive. At the same time, due to the heavy beams, it is difficult to ensure the installation accuracy during installation, and there are certain safety hazards. The existing load-bearing columns may have air bubbles in the concrete grout during pouring, which will affect the overall structural strength of the load-bearing columns, causing unnecessary safety hazards
