Abstract
The present invention relates to a prefabricated cavity component for reinforced concrete, which comprises reinforced concrete sliver bottom plate (1) and at least two longitudinal ribs (2), wherein the longitudinal ribs (2) are crossed with the bottom plate (1), and a groove-shaped component is formed. The present invention is characterized in that groove-shaped overhead plates (3) with downward openings are alternately arranged between the longitudinal ribs (2); the gap between every two adjacent groove-shaped overhead plates (3) is a rear casting concrete transverse rib mould cavity (4); holes (5) communicated with the transverse rib mould cavities (4) are arranged on the longitudinal ribs (2) on the bottom plate (1). Thus, when the canity component applies to hollow plates for construction, the dosage of cast-in-situ concrete can be reduced by the groove-shaped component, weight of the hollow plates is reduced, construction cost is lowered, and bearing capacity of floor slabs is enhanced. The present invention has the characteristics of good mechanical property, convenient construction, simple structure, material saving, low cost, etc. The present invention is suitable for hollow plates, hollow building plates, roofs, foundation plates, wall bodies and hollow bridge beams made of cast-in-situ reinforced concrete or prestressed reinforced concrete, especially for flat slab roofs.
Description
(1) technical field
The present invention relates to a kind of steel bar concrete prefabricated cavity member.
(2) background technology
With Ribbed Bar concrete cavity component assembly hollowcore slab, can bear bidirectional load, do not need on-the-spot formwork, and cost is low, lifting, transportation are easily.This Cavity structural member with ribbing comprises strip base plate, strip longitudinal rib, and longitudinal rib and base plate connect into integral body.The longitudinal rib length of common this Cavity structural member is consistent with floor length, when bearing the hollowcore slab of bidirectional load with this Cavity structural member assembly unit formation, Cast-in-place concrete can't pass through at the longitudinal rib position, the Cast-in-place concrete rib that intersects with longitudinal rib that can not form connection, simultaneously, in the direction vertical with longitudinal rib, 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 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 steel bar concrete prefabricated cavity member for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of steel bar concrete prefabricated cavity 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 rectangular base plate of steel bar concrete, at least two longitudinal ribs, longitudinal rib and base plate intersect, constitute channel member, it is characterized in that being spaced between the described longitudinal rib downward opening groove-shaped frame hollow plate, be spaced apart rear pouring concrete cross rib die cavity between the adjacent flute profile Roofing slab, have hole to communicate on the longitudinal rib on the base plate with the cross rib die cavity.Like this, owing to be spaced downward opening groove-shaped frame hollow plate between the longitudinal rib, thereby when Cavity structural member was applied to the hollowcore slab construction, channel member can reduce the Cast-in-place concrete consumption, alleviates hollowcore slab weight, reduced construction cost, improved the supporting capacity of floor; Simultaneously, owing to be spaced apart rear pouring concrete cross rib die cavity between the adjacent flute profile Roofing slab, there is hole to communicate on the longitudinal rib on the base plate with the cross rib die cavity, thereby Cavity structural member is when being used to construct, hole position at longitudinal rib, Cast-in-place concrete can smooth and easy passing through, and forms the Cast-in-place concrete rib that intersects with longitudinal rib that is communicated with, with the cast-in-place and prefabricated two-way rib structure that combines of the common formation of longitudinal rib, and, in the direction vertical with longitudinal rib, can lay various pipelines very swimmingly by the hole on the longitudinal rib, no longer need the scene to burrow, thereby, the intensity height of Cavity structural member, rigidity is big, good integrity; 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.
