Abstract
The invention discloses a cast reinforced concrete hollow floor system which includes an upper cast reinforced concrete layer and a lower cast reinforced concrete layers; a plurality of combined box inserts are longitudinally and laterally in the upper and the lower cast reinforced concrete layers; each combined box insert consists of at least two parts which are buckled together and a concrete reinforced rib is arranged between two adjacent inserts. The inserts are arranged in the cast reinforced concrete as templates, to form regular cavities in the cast reinforced concrete, so as to reduce consumption of the concrete and the weight of the structure; such inserts will not taken out any more after construction but form an integral structure together with the reinforced concrete, so that the volume core ratio of the reinforced concrete is greatly improved; in addition, similarity of the floor slabs provides more reasonable stress, greater bearing capacity and better seismic performance; therefore, the invention is in particular applicable to the cast reinforced concrete hollow floor slabs of multi- or high-storeyed buildings and large span structures.
Description
Technical field
The present invention relates to a kind of building unit, especially relate to a kind of cast-in-situ reinforced concrete hollow floor.
Background technology
At present, the used inner membrance of cast-in-situ reinforced concrete hollow floor commonly used both at home and abroad is an in-core mould, and be characterized in: the floor hollow rate is low; The stiffness differences of floor both direction is bigger, and stressed unfavorable to floor, anti-seismic performance is bad.
Summary of the invention
Purpose of the present invention just is to provide a kind of more reasonable structure, floor hollow rate height, the better cast-in-situ reinforced concrete hollow floor of performance.
Purpose of the present invention can realize by following measure:
The present invention includes cast-in-situ steel reinforced concrete layer up and down, be provided with a plurality of combined box internal molds along length and width in the cast-in-situ steel reinforced concrete layer up and down, the combined box internal mold is made of the two parts at least that snap together, and faces mutually to be the concrete ribs between the internal mold.
A plurality of combined box internal molds are to be distributed in the layer of concrete among the present invention.Perhaps, a plurality of combined box internal mold integral body are vertically and horizontally arranged and are distributed in the layer of concrete.Perhaps, a plurality of combined box internal mold integral body are circle-shaped and are distributed in the layer of concrete.Certainly, also can arrange according to other rule.The combined box internal mold is rectangular shape or square shape or drum etc., also can be other suitable shapes certainly.The combined box internal mold is to be made of two parts up and down.Perhaps, the combined box internal mold is to be made of four parts.Perhaps, the combined box internal mold is to be made of many parts.The combined box internal mold is provided with ribs.
The present invention makes the cavity of the inner formation rule of cast-in-situ steel reinforced concrete because the combined box internal mold that adopts two parts to constitute is placed in cast-in-situ steel reinforced concrete inside with it and serves as template, thereby reduces concrete amount, alleviates dead load; Described internal mold no longer takes out after construction finishes, and forms structural entity with steel concrete.Make steel concrete volume hollow rate improve greatly, and floor two homogenies, more reasonable stress, bearing capacity is bigger, and anti-seismic performance is better, is specially adapted to the cast-in-situ reinforced concrete hollow floor of all multi-rise buildings and longspan structure.
