Embodiment 2

[0032] The difference between the assembled support of the large-span steel truss floor deck in this embodiment and the assembled support of the large-span steel truss floor deck in Embodiment 1 is that the beam is divided into two sections, and the two sections of beam are connected by a telescopic device . The beam is divided into two sections: a first channel steel 3 and a second channel steel 4; Web welding; the strip connecting steel plate 5 is provided with two parallel strip holes 9 along the length direction, and the first channel steel 3 is provided with round holes matching the two strip holes 9; The other end of the strip-shaped connecting steel plate 5 is fixedly connected with the first channel steel 3 through the strip-shaped hole 9 and the round hole through the second high-strength bolt 8 . Two strip connecting steel plates 5 are respectively located on the inner and outer sides of the web of the second channel steel 4 .

Abstract

The invention belongs to the technical field of prefabricated building construction and particularly relates to a large-span steel bar truss floor bearing plate assembling type supporting constructionmethod which comprises the following steps of S1, preparing two I-shaped steel beams, and uniformly welding a plurality of force bearing steel plates on the I-shaped steel beams respectively, whereinthe force bearing steel plates are welded to webs and upper wing plates of the I-shaped steel beams respectively; S2, symmetrically arranging the two I-shaped steel beams in parallel, arranging a plurality of channel steel cross beams between the two I-shaped steel beams, and fixedly connecting the two ends of the channel steel cross beams with the corresponding force bearing steel plates throughfirst high-strength bolts; and S3, mounting a steel bar truss floor bearing plate on support erected by the I-shaped steel beams and the channel steel cross beams. In the large-span steel bar truss floor bearing plate assembling type supporting construction method, by adopting assembling type telescopic detachable force bearing beams to support the steel bar truss floor bearing plate, the supporting problem of the large-span steel bar truss floor bearing plate is solved, the supporting effect to the high-altitude large-span steel bar truss floor bearing plate is especially remarkable, materials and labor are saved, and the support can be detached for reuse after concrete pouring of the floor bearing plate is finished.

Description

technical field [0001] The invention belongs to the technical field of prefabricated building construction, and in particular relates to a large-span reinforced truss floor deck assembled support and a construction method. Background technique [0002] At present, prefabricated buildings have become a development trend and are developing rapidly. Prefabricated steel structures have high construction efficiency, less labor intensity than concrete structures, and are green and environmentally friendly. The steel truss floor deck in the prefabricated steel structure building is an important part of the prefabricated steel structure. It is processed in a factory and assembled on site. However, the steel truss floor deck has insufficient rigidity in the long-span structure, and it is necessary to erect a bracket For support, the workload of erecting steel pipe fastener brackets is heavy, and construction resources need to be increased. Aiming at the support problem in the constr...
