Suspended formwork structure of steel structure composite floor slab

Abstract

The invention provides a suspended formwork structure of a steel structure composite floor slab, and belongs to the technical field of building construction. The suspended formwork structure comprises a steel structure beam; the inner sides of a pair of I-shaped beams of the steel structure beam along the length direction are respectively provided with a row of first mounting holes at intervals; each first mounting hole is internally provided with a hanging part; the two rows of first mounting holes in the inner sides of the pair of I-shaped beams are in one-to-one correspondence; steel pipes are erected on the two hanging parts in one-to-one correspondence in the width direction of the steel structure beam; first square battens are arranged between the upper portions of the two ends of each steel pipe and the corresponding I-shaped beam in a clamped mode; second square battens are arranged on all the steel pipes in the length direction of the steel structure beam at intervals; a formwork is placed on the upper portion of the second square battens; and the upper surface of the formwork is flush with the upper surface of the steel structure beam. According to the suspended formwork structure of the steel structure composite floor slab, the structure is simple and reliable, the construction efficiency is high, the lower construction operation space is saved, interpenetration operation is facilitated, the construction period is shortened, most parts can be reused, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a hanging formwork structure of a steel structure composite floor slab. Background technique [0002] At present, the cast-in-place floor slabs of steel structures mostly use truss floor slabs, profiled floor slabs and traditional floor supports. Among them, the full house floor support needs to be erected on the ground or the next floor. Such erection has a long construction period, a large investment in turnover materials, and a high investment cost. It can only be carried out after the support is removed, which restricts the construction of the lower layer; especially for super high formwork, there is a safety hazard of poor overall stability due to the full house support. [0003] In addition, the use of truss floor slabs or profiled floor slabs requires the use of crane equipment to assist hoisting first, which takes up the use of hoisting equipment and vertic...

Problems solved by technology

Among them, the full house floor support needs to be erected on the ground or the next floor. Such erection has a long construction period, a large investment in turnover materials, and a high investment cost. It can only be carried out after the support is removed, which restricts the construction of the lower floor; especially for super high formwork, there is a safety hazard due to poor overall stability of the full house support

[0003] In addition, the use of truss floor slabs or profiled floor slabs requires the use of crane equipment to assist hoisting first, which takes up the use of hoisting equipment and vertical transportation time of cranes, and the cost of mechanical shifts is high; secondly, steel truss formwork or profiled steel plates The steel content of the floor deck is high, and the cost is high; moreover, it is difficult to bind the steel bars of the steel truss formwork; while the profiled steel floor deck ribs are relatively high, and the thickness of the floor structure layer is large, which reduces the net height of the building and lowers the floor. The surface is wavy, the bottom of the slab is uneven and unsightly, the two-way rigidity of the floor is inconsistent, and the binding of steel bars is cumbersome.
