Abstract
A pre-fabricated component for hollow reinforced concrete consists of a long substrate, at least two longitudinal vertical walls on the substrate to form a whole body, in parallel or crossed. At least two hollow over-linked bodies and/or fillers lighter than concrete are arranged on the substrate. Some lateral rib cavities are located between the said over-linked bodies and/or fillers. A lateral constructing plate is arranged in at least one of the lateral rib cavities to support the adjacent vertical walls. The hollow over-linked bodies and the lighter fillers can reduce amount of concrete cast in site so as to reduce the weight of the pre-fabricated component, to reduce cost, and to increase strength of the hollow component. It is used for lightweight plate of reinforced concrete cast in site or pre-stressed reinforced concrete, hollow roof, basement, wall or hollow bridge beam, especially for hollow beamless roof.
Description
(1) technical field
The present invention relates to a kind of concrete hollow board prefabricated units.
(2) background technology
Floor spiced with the Ribbed Bar concrete prefabricated element, can bear bidirectional load, do not need on-the-spot formwork, and cost is low, lifting, transportation are easily.This prefabricated units with ribbing comprise concrete base plate, concrete longitudinal vertical plate, and the concrete longitudinal vertical plate stands on the concrete base plate, and are linked to be integral body with the concrete base plate.The concrete longitudinal vertical plate length of common this prefabricated units is consistent with the concrete floor length, when forming floor with this splicing prefabricated components, behind Cast-in-place concrete, the floor of assembly unit is solid, the concrete feed consumption is many, and floor weight is big, is not suitable for large span and builds, therefore, develop a kind of novel concrete hollow board and be urgent need with prefabricated units.
(3) summary of the invention
The object of the present invention is to provide a kind of concrete hollow board prefabricated units, when being applied to the hollowcore slab construction, have characteristics such as easy construction, saving concrete consumption, reduction construction cost.
Solution of the present invention is on the basis of existing technology, comprise the rectangular base plate of steel bar concrete, the rectangular longitudinal vertical plate of steel bar concrete, longitudinal vertical plate is arranged on the base plate, and form whole, it is characterized in that at least two longitudinal vertical plates are parallel or crossing, at least two built on stilts bodies that form cavitys are housed or/and than the obturator of concrete lightweight on the base plate, built on stilts body has the transversary frid of an adjacent longitudinal vertical plate of support or/and be the cross rib die cavity between the obturator at least one the cross rib die cavity between two longitudinal vertical plates.Like this, because described at least two longitudinal vertical plates are parallel or crossing, at least two built on stilts bodies that form cavitys are housed or/and than the obturator of concrete lightweight on the base plate, thereby when prefabricated units are applied to the hollowcore slab construction, built on stilts body or obturator can reduce the Cast-in-place concrete consumption, alleviate hollowcore slab weight, reduce construction cost, improve the supporting capacity of hollowcore slab, simultaneously, make somebody a mere figurehead body or/and be the cross rib die cavity between the obturator, thereby can form the Cast-in-place concrete cross rib, reduce the vertical cross stiffness difference of hollowcore slab at mould rib die cavity position, and, a transversary frid that supports adjacent longitudinal vertical plate is arranged at least one the cross rib die cavity between two longitudinal vertical plates, thereby the intensity of prefabricated units is higher, rigidity is bigger, thereby has reached purpose of the present invention, in addition, prefabricated units also have simple in structure, make characteristics such as easy, be applicable to the thistle board of cast-in-situ reinforced concrete or prestressed reinforced concrete, hollowcore slab, roof system, sole plate, body of wall and hollow bridges are used, and are specially adapted to hollow arch without beam and use.
