Novel bidirectional inverted-T-shaped beam combined floor

Abstract

The invention provides a novel bidirectional inverted-T-shaped beam combined floor which is applied to building structures in the engineering field. The novel bidirectional inverted-T-shaped beam combined floor comprises octothorpe-shaped components which are composed of a plurality of inverted-T-shaped steel beams. A plurality of small holes are sequentially formed in webs of the inverted-T-shaped steel beams of the octothorpe-shaped components. Steel bars are arranged between the small holes in the webs of the inverted-T-shaped steel beams in a crossed mode. The multiple octothorpe-shaped components form a bidirectional steel rib structure through splicing joints, and the bidirectional steel rib structure has a stress function during construction. Light prefabricated plates serving as a permanent formwork of the floor sequentially arranged in all cells of the bidirectional steel rib structure, and concrete is evenly poured on the bidirectional steel rib structure and the light prefabricated plates. The novel bidirectional inverted-T-shaped beam combined floor has the characteristics of being high in strength and rigidity and good in ductility; and formwork supporting is not needed, construction is easy, operation is easy, the self weight is low, the height of a structural layer is small, the effective service space is increased, and the economic benefits are good.

Description

technical field [0001] The invention relates to a composite floor, in particular to a novel two-way inverted T-beam composite floor used in building structures in the engineering field. Background technique [0002] At present, as the country vigorously develops the industrialization of steel structure housing, steel structure housing can not only meet the requirements of sustainable development of building resources, but also help accelerate the process of housing industrialization, meet the requirements of rapid urbanization, and conform to the national industrial policy , has broad application prospects. [0003] In order to realize the intensive and factory production of steel structure residences and accelerate the development of steel structure residences, it is first necessary to solve the structural system problems that affect the development of steel structure residences, such as the floor system, so that it can achieve standardization, serialization, and mass produ...

Problems solved by technology

However, in the traditional composite flat beam floor, the connection between the steel beam and the concrete is realized by setting the shear parts, and the setting of the shear parts is complicated and cannot guarantee the combined effect of the steel beam and concrete well.

In addition, the traditional composite flat-beam slabs mostly adopt one-way slab layout, and the slab thickness is relatively large.
