Abstract

A reinforced lightweight concrete comprises concrete cast in site, pre-fabricated components as fillers spaced each other and contained in the former, and some ribs are cast in site between the said fillers. The pre-fabricated components consist of a slender reinforced concrete substrate and at least two vertical walls. The vertical walls are arranged on the substrate in parallel or perpendicularto form a whole body. At least two over-linked bodies and/or fillers lighter than concrete are arranged on the substrate to form cavities. Between the vertical walls, at least one lateral constructionplate is combined with the substrate to form a whole body. The concrete can be used as hollow roof, basement, wall or hollow bridge beam.

Description

A kind of lightweight concrete board

(1) technical field

The present invention relates to a kind of lightweight concrete board.

(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 lightweight concrete board for being badly in need of.

(3) summary of the invention

The object of the present invention is to provide a kind of lightweight concrete board, 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 cast-in-situ reinforced concrete, fill and use prefabricated units, filling with prefabricated units each other alternately, and wrap up in and be contained in the cast-in-situ reinforced concrete, filling is the Cast-in-place concrete rib with prefabricated units each other, filling comprises the rectangular base plate of steel bar concrete with prefabricated units, 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, between longitudinal vertical plate, there be at least one to connect to integral body, simultaneously connect into whole transversary fagging with at least two longitudinal vertical plates with base plate.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 built on stilts body or obturator can reduce the Cast-in-place concrete consumption, alleviate thistle board weight, reduce construction cost, improve the supporting capacity of thistle board, simultaneously, between longitudinal vertical plate, have at least one with base plate connect to integral body, connect into whole transversary fagging with at least two longitudinal vertical plates simultaneously, thereby the intensity of prefabricated units is higher, rigidity is bigger, in addition, lightweight concrete board also has simple in structure, make characteristics such as easy, thereby reached purpose of the present invention, be applicable to the hollow building cover of cast-in-situ reinforced concrete or prestressed reinforced concrete, roof system, sole plate, body of wall and hollow bridges are used, and are specially adapted to hollow arch without beam and use.

Feature of the present invention is that also described base plate stretches out longitudinal vertical plate and constitutes toss outward.Like this, when member was applied in the Cast-in-place concrete thistle board, base plate stretched out longitudinal vertical plate and constitutes toss outward and can replace construction formwork, reduces the template loss, reduces material cost, can save the template installation procedure simultaneously, accelerates speed of application, improves efficiency of construction.
