At least two lightweight blocks are filled in the trough. At least one pre-stressed steel bar is respectively arranged in the substrate and on the top of each side wall. The lightweight blocks are spaced each other to form internal rib cavities, which are perpendicularly or tilted with the side walls. Some notches are arranged on the side walls and connecting piers are arranged on top of the notches. It can be used for hollow board, roof, substrate, wall or hollow bridge beam.
Description
(1) technical field
The present invention relates to a kind of concrete hollow board Cavity structural member.
(2) background technology
With Ribbed Bar concrete prefabricated element assembled light plate, 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 strip base plate, strip side plate, and side plate and base plate connect into integral body, constitute T shape or rectangular channel member.The side plate length of common this prefabricated units is consistent with floor length, when bearing the thistle board of bidirectional load with this splicing prefabricated components formation, Cast-in-place concrete can't pass through at the side plate position, the Cast-in-place concrete rib that intersects with side plate that can not form connection, simultaneously, in the direction vertical with side plate, various pipe line arrangement need the scene threading that burrows, both wasted concrete material, waste man-hour again, and, behind the Cast-in-place concrete, the thistle board of assembly unit is solid, the concrete feed consumption is many, and thistle board 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 Cavity structural member.
(3) summary of the invention
The object of the present invention is to provide a kind of concrete hollow board Cavity structural member, have that mechanical property is good, easy construction, simple in structure, save characteristics such as material, cost are low.
Solution of the present invention is on the basis of existing technology, comprise the steel bar concrete base plate, article at least two, steel bar concrete side plate, side plate stands upright on the base plate, constitute strip frid member, it is characterized in that being filled with at least two lightweight filling blocks in the strip groove of described strip frid member, at least one vertical elongated prestressed reinforcement arranged in the base plate of the bottom of side plate, at least one vertical elongated prestressed reinforcement arranged at the top of side plate, the lightweight filling block is provided with at interval, be the internal-rib cavity each other, jagged on internal-rib cavity and side plate quadrature or oblique, the lightweight filling block side plate between at interval, the drawknot pier drawknot of side plate is arranged on the breach.Like this, owing to be filled with at least two lightweight filling blocks in the strip groove of described strip frid member, thereby when Cavity structural member is applied to the hollowcore slab construction, peviform lightweight filling block can reduce the Cast-in-place concrete consumption, alleviate hollowcore slab weight, reduce construction cost, improve the supporting capacity of hollowcore slab; Simultaneously, owing in the base plate of the bottom of side plate at least one vertical elongated prestressed reinforcement arranged, at least one vertical elongated prestressed reinforcement arranged at the top of side plate, thereby intensity height, the rigidity of Cavity structural member are big, good integrity; And, because the lightweight filling block is provided with at interval, be the internal-rib cavity each other, internal-rib cavity and side plate quadrature or oblique, jagged on the side plate between the lightweight filling block interval, the drawknot pier drawknot that side plate is arranged on the breach, thereby in the gap portions of side plate, Cast-in-place concrete can smooth and easy passing through, and forms the Cast-in-place concrete rib that intersects with side plate that is communicated with, with the cast-in-place and prefabricated two-way rib structure that combines of the common formation of side plate, simultaneously, in the direction vertical with side plate, can lay various pipelines very swimmingly by the breach on the side plate, no longer need the scene to burrow; Therefore, this Cavity structural member has that mechanical property is good, easy construction, simple in structure, save characteristics such as material, cost are low, thereby reached purpose of the present invention, simultaneously, Cavity structural member also has characteristics such as intensity height, rigidity is big, making is easy, the hollowcore slab, hollow building cover, roof system, sole plate, body of wall and the hollow bridges that are applicable to cast-in-situ reinforced concrete or prestressed reinforced concrete are used, and are specially adapted to hollow arch without beam and use.
