Description
Technical field
The present invention relates to a kind of band Y shape cast-in-place core body floor of steel plate lightweight and construction method.Belong to building engineering field, be applicable to industry and construct with the light floor in civilian construction.
Background technology
The function of floor mainly splits floor, forms space, and for resident family provides the platform of inhabitations, activity, work, it should have enough rigidity to prevent vibration, satisfied to insulate against sound, the requirement of heat insulation and fire-proof function.Floor slab structure system directly bears the various dead load and live load that are applied to it, and these loads is delivered to the vertical loadbearing member such as beam, post.Floor will have enough horizontal rigidities and globality in own layer, reliably will be connected with vertical member simultaneously, ensures stablizing and transmitting horizontal force of vertical member.The selection of floor scheme is subject to the restriction of several factors, and primary essential is the requirement meeting building function, ensures that structural safety is reliable, is putting the quality weighing a scheme with economic indicator before this.
In-situ reinforced concrete slab is most widely used at present, has good integrity, feature that horizontal rigidity is large, but with regard to building house, also there are some shortcomings: 1, the more difficult control in crack such as contraction, the temperature difference, sedimentation of cast-in-situ concrete.2, complicated construction technique, long in time limit; A large amount of situ wet operations also can cause noise and environment pollution.3, cast-in-place concrete floor is from great, can bring many adverse effects thus.
Existing a kind of odd-shaped cross section light material fills prestressed in-situ depositing plate (ZL:03236988.3) at present, is made up of light material filler and Bars In Poured Concrete Slab.This structure achieves certain effect under suitable engineering specifications, but the connection of light material filling block bottom and Bars In Poured Concrete Slab is not done and specifically illustrates, easily when concreting, light material offsets, and the On The Floating of light material is only limited by floating limit steel bar when building floorslab concrete, DeGrain.
In sum, light floor industry with civilian construction in application get more and more, need badly at present invention a kind of structural integrity good, the duration is short, have the cast-in-place core body floor of the lightweight of good anti-seismic performance.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide one to alleviate deadweight, reduce comprehensive cost, be conducive to antidetonation, the cast-in-place core body floor of band deformed steel flats lightweight of easy construction and construction method.
