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 in the strip groove of described strip frid member at least two built on stilts boxes of sealing, 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 built on stilts box of sealing is provided with at interval, be the internal-rib cavity each other, jagged on internal-rib cavity and side plate quadrature or oblique, the built on stilts box of the sealing 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 built on stilts boxes of sealing in the strip groove of described strip frid member, thereby when Cavity structural member is applied to the hollowcore slab construction, the built on stilts box of sealing 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 built on stilts box of sealing 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 built on stilts box of the sealing 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.
Feature of the present invention also is to have between the described side plate drawknot concrete or the mortar fagging of at least one horizontal drawknot adjacent side plates.Like this, laterally the drawknot concrete or the mortar fagging of drawknot adjacent side plates can play the good supporting reinforcement effect to side plate, can guarantee the quality of Cavity structural member effectively, improve its intensity and rigidity, and simultaneously, its overall performance is better.
Feature of the present invention is that also there is the drawknot concrete or the mortar fagging of drawknot side plate the end of described side plate.Like this, drawknot concrete or mortar fagging can play the good supporting reinforcement effect to side plate, can guarantee the quality of Cavity structural member effectively, when Cavity structural member be applied to cast-in-place concrete cored in the time, fagging can combine with Cast-in-place concrete and form superimposed rib structure, can further improve the force structure of hollowcore slab inside.
Feature of the present invention is that also described drawknot concrete or mortar fagging and steel bar concrete base plate connect to integral body.Like this, drawknot concrete or mortar fagging have been linked to be whole primary structure member with side plate and base plate, make drawknot concrete or mortar fagging and side plate can bear the stress of two different directions, when Cavity structural member be applied to cast-in-place concrete cored in after, can further improve the structural performance of hollowcore slab.
Feature of the present invention also is to have on the described internal-rib cavity drawknot pier drawknot between the built on stilts box of sealing.Like this, when the drawknot pier drawknot that seals between the built on stilts box is arranged on the internal-rib cavity, the drawknot pier has connected into integral body with the built on stilts box of adjacent sealing, and the drawknot pier has played the effect that the built on stilts box of adjacent sealing is positioned in the internal-rib cavity, can guarantee the quality of Cavity structural member effectively.
