Embodiment Construction

[0082] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0083] Such as Figure 1-22 As shown, the prefabricated assembled steel truss composite floor slab provided by the present invention

[0084] Including the bottom slab assembled from prefabricated slabs, and the pouring layer poured above the bottom slab and between the joints of the prefabricated slabs; the prefabricated slab adopts I-type prefabricated slab 1 or I-type I-type prefabricated slab 2:

[0085] Among them, the I-type prefabricated slab 1 includes a reinforced truss floor deck composed of the first upper chord steel bar 11, the first lower chord steel bar 12, the first web 13 and the first bottom steel plate 14; the left side of the first bottom steel plate 14 There are multiple sets of first channel steel 15 for prefabricated panel assembly, and multiple sets of first channel steel 15 for prefabricated panel assembly or second c...

Abstract

The invention relates to a prefabricated steel bar truss combined floor and a splicing method thereof. The prefabricated steel bar truss combined floor is characterized by comprising a bottom board and poured layers, wherein the bottom board is formed by assembling prefabricated boards, the poured layers are poured on the bottom board and in gaps between prefabricated board splicing seams, and prefabricated boards I or prefabricated boards II are adopted as the prefabricated boards. Compared with the prior art, the prefabricated steel bar truss combined floor has the advantages that the prefabricated steel bar truss combined floor comprises the bottom board formed by assembling the prefabricated boards and the poured layers poured on the bottom board and in the gaps between the prefabricated board splicing seams, and light-weight aggregate concrete can be adopted as poured concrete, so that the weight of the overall structure is reduced, the foundation construction cost is lowered, the seismic performance of a building structure is improved, and high carrying capacity is achieved; prefabricated construction can be achieved, so that the construction period is greatly shortened, and construction is convenient; bottom steel plates of the prefabricated boards are completely wrapped in the concrete in the prefabrication process, so that secondary treatment on the bottom steel plates is not needed.

Description

technical field [0001] The invention relates to a prefabricated assembled composite floor slab and a splicing method thereof, belonging to the field of structural engineering. Background technique [0002] At present, the floor slabs in buildings often adopt three forms: cast-in-place slabs, profiled steel plate composite slabs and reinforced truss composite floors. Cast-in-place slabs have processes such as formwork support, steel plate layout, and formwork removal. The on-site workload is heavy, the efficiency is low, and the steel bars are easy to shift, causing quality degradation. In addition, with the increase in labor costs, construction costs have increased significantly. [0003] Compared with the cast-in-place floor slab, the profiled steel plate composite floor slab saves the formwork support process. Since the profiled steel plate has ribs of a certain height, the total thickness of the floor slab is generally slightly thicker, the indoor net height of the buildi...
