Problems solved by technology

[0003] Traditional building structures mostly use reinforced concrete floor slabs or profiled steel plate composite floor slabs. The inventors found that the former has a long construction period, high cost, complicated process, and heavy weight, which often leads to large-scale damage under the action of earthquakes. Although the latter The weight has been reduced, but the passage of installation equipment such as installation pipelines cannot be guaranteed

Embodiment 2

[0043] This embodiment discloses a combined floor slab. The only difference from Embodiment 1 is that prestressed steel bars are embedded in the mortar of the second steel pipe, which further enhances the strength and bending rigidity of the second steel pipe. Other structures and embodiments 1 is the same and will not be repeated here.

Embodiment 3

[0045] This embodiment discloses a building, which is provided with the combined floor slabs described in Embodiment 1 or 2, and other structures of the building adopt existing structures, which will not be described in detail here.

Embodiment 4

[0047] This embodiment discloses a construction method of the combined floor slab described in Embodiment 1. The bottom ends of a plurality of vertical columns are welded and fixed to the lower steel plate by high-frequency welding, and the top ends of the plurality of vertical columns are welded and fixed by high-frequency welding. The method is welded and fixed with the upper steel plate.

[0048] The second steel pipe is poured with mortar, the first and second steel bars that are pre-bent in a wave-like structure are welded and fixed to the second steel pipe respectively, and the wave crest positions of the first and second steel bars are welded and fixed to the second steel pipe to form In the truss structure, the trough positions of the first steel bar and the second steel bar are welded and fixed with the upper surface of the upper steel plate.

[0049] Weld studs on the upper surface of the upper steel plate.

[0050] After the welding of the welding nails, concrete is ...

Abstract

The invention relates to a combined floor slab, a building and a construction method, comprising an upper steel plate and a lower steel plate, a plurality of columns are fixed between the upper steel plate and the lower steel plate, a concrete slab is poured on the upper surface of the upper steel plate, and a concrete slab is embedded in the concrete slab There are multiple rows of truss structures, and the truss structures are fixed with the upper steel plates. The combined floor slab of the present invention is light in weight and convenient for later installation of pipelines.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a combined floor slab, a building and a construction method. Background technique [0002] The statements herein merely provide background related to the present invention and do not necessarily constitute prior art. [0003] Traditional building structures mostly use reinforced concrete floor slabs or composite floor slabs of profiled steel plates. The inventors found that the former has long construction period, high cost, complicated procedures, and is self-heavy, which often leads to large-scale damage under the action of earthquakes. The weight is reduced, but the passage of installation equipment such as installation pipelines cannot be guaranteed. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a combined floor slab with light weight and convenient later pipeline install...
