Pipeline-separated fabricated invisible beam laminated floor slab installed from top to bottom

Abstract

The invention discloses a pipeline-separated fabricated invisible beam laminated floor slab installed from top to bottom. The pipeline-separated fabricated invisible beam laminated floor slab installed from top to bottom comprises a laminated floor slab prefabricated layer, concrete vertical columns, a laminated floor slab cast-in-place layer and cement fiber boards; the laminated floor slab prefabricated layer is prefabricated in a factory, prefabricated panels are hoisted from top to bottom on the scene, firstly, an outward extending steel bar truss on one side of the laminated floor slab prefabricated layer is placed on the upper surfaces of lower flanges of steel beams on one side, then position adjustment is carried out to place an outward extending steel bar truss on the other side of the laminated floor slab prefabricated layer on the upper surfaces of lower flanges of steel beams on the other side, and the outward extending steel bar trusses are used for fixing; after the prefabricated panels are hoisted in place, upper concrete is poured, and pipelines are laid through reserved holes formed in both sides of beam webs; and finally, the cement fiber boards are installed on both sides of the steel beams to achieve closure. According to the fabricated invisible beam laminated floor slab, the purpose of pipeline separation is achieved, the steel beams are concealed in the floor slab, the fireproof and anti-corrosion problems of the steel beams are solved to a certain extent, flexible arrangement of a wall body can be realized, and cavities formed inside the steel beamsplay roles of thermal insulation and sound insulation.

Description

technical field [0001] The invention relates to the technical field of building structural components, in particular to an assembled invisible beam laminated floor slab installed from top to bottom with separate pipelines, which is suitable for prefabricated buildings. Background technique [0002] At present, the assembly technology for the main structure of prefabricated buildings is relatively mature, but the three-board system that matches the main structure is relatively backward. [0003] After the prefabricated concrete laminated floor slab is fixed by the triangular steel truss processed in the factory, the concrete is poured to form a prefabricated thin slab, and after being hoisted in place, the laminated layer concrete is poured. This form has the advantages of good integrity, high rigidity, good seismic performance, fast construction, saving formwork, etc. of cast-in-place slabs, and can realize assembly construction. But the existing prefabricated concrete lami...

AI Technical Summary

Problems solved by technology

[0004] 1) Various pipelines in the laminated floor are pre-buried in the structural layer of the floor, failing to realize the separation of pipelines and building structural systems, which is not conducive to the inspection, maintenance and renewal of pipelines and equipment;

[0005] 2) The laminated floor slab is placed on the beam, which fails to hide the beam and fails to meet the flexible layout of the wall in the lower space

And failed to effectively solve the problem of fire prevention and corrosion of steel beams
