Abstract
The present invention relates to a cavity member for a hollow concrete slab, which comprises at least one long pipe body (1) with a longitudinal long hole. The shape of the cross section of the longpipe body (1) is in the shape of a quadrangular pipe. The present invention is characterized in that the lower pipe wall (2) of the long pipe body (1) is an integral through entire flat slab; other pipe walls of the long pipe body (1) are provided with at least one lateral rib slot (3) which is vertical to or obliquely crossed with an axis of the pipe. At least one position of the pipe wall between the lateral rib slots (3) is provided with a connector (4) which is connected with the lateral rib slots (3). Thus, the cavity member has the advantages of simple and convenient manufacture, and low production cost. The rigidity difference between the longitudinal and the lateral directions of the cast-in-place concrete hollow slab can be greatly reduced, and a bidirectional hollow slab can be formed so that the mechanical property of the hollow slab can be greatly enhanced. The cavity member has the advantages of high intensity, strong rigidity and convenient transportation and construction, and is not easy to break off. The present invention is suitable for various hollow slabs, hollow floors, roofs, walls, foundation base slabs or hollow bridges, and especially hollow flat slab floors, which are made from cast-in-place reinforced concrete or prestressed reinforcement concrete to use.
Description
(1) technical field
The present invention relates to a kind of concrete hollow board Cavity structural member.
(2) background technology
At present, in the prior art, cast-in-place concrete cored one-tenth pole is permanent core, and as paper tube, plastic pipe, metal bellows, core light material etc., these tubular core molds or member mainly consider to find time concrete, reduce the weight of hollowcore slab.It as the patent No. of applicant application " cast-in-place reinforced concrete filling fiber reinforcement type thin wall cylinder " utility model patent of 99249755.8, it is made up of horniness thin-walled tube and two ends plug, two plugs form an enclosed cavity with the horniness thin-walled tube closed at both ends, and horniness thin-walled tube cross section and plug shape can be circle, square, trapezoidal or other is special-shaped.This pipe has advantages such as intensity height, resistance to deformation, anti-vibration performance are good, convenient construction and transport.But be applied to cast-in-place concrete cored after; because the tubulose concrete in the horniness thin-walled tube centre in cast-in-place concrete cored is found time; along pipe the Cast-in-place concrete rib arranged vertically; and laterally found time by core or member owing to steel bar concrete; only depend on two plugs to seal as the power transmission rib; therefore; can't bear the effect of complicated pulling force, pressure, shearing, moment of torsion etc.; the bigger situation of cast-in-place concrete cored two direction rigidity great disparities has appearred; and become the cast-in-situ reinforced concrete hollow one-way slabs, can't form well word rib equivalent transverse and longitudinal.Therefore, develop a kind of novel concrete hollow board and be urgent need with Cavity structural member.
