The present invention is characterized in that the pipe body (1) is provided with at least one groove (3). In this way, the pipe body (1) is provided with the groove (3), and transverse ribs can be formed in the groove (3) by cast-in-situ concrete, and therefore, the difference of the longitudinal stiffness and the lateral stiffness of a cast-in-place concrete hollow plate is greatly reduced, and a bidirectional hollow plate can be formed, which greatly improves the mechanical property of the hollow plate. Simultaneously, the hollow pipe also has the characteristics of high strength, easy manufacture, low cost, easy construction and transportation, etc. The present invention is suitable for various hollow floors, roofs, foundation slabs, walls or hollow bridges which are respectively made of cast-in-situ reinforcement concrete or prestressed reinforcement concrete, and is especially suitable for hollow beamless floors.
Description
(1) technical field
The present invention relates to a kind of concrete hollowed pipes.
(2) background technology
At present, in the prior art, it is permanent core that cast-in-situ concrete hollow floor becomes pole, 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 superstructure weight.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 after being applied to cast-in-situ concrete hollow floor; because the tubulose concrete in the horniness thin-walled tube centre in the Cast-in-place Concrete Building Floor 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 hollowed pipes for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of concrete hollowed pipes, be applied to cast-in-situ concrete hollow floor after, can form two-way hollowcore slab, simultaneously, hollow section also has the intensity height, makes easily, characteristics such as cost is low, convenient construction and transport.
Solution of the present invention is on the basis of existing technology, comprise body and pipe end end socket, two pipe end end sockets form the enclosed cavity hollow section with the shutoff of body two ends, it is characterized in that body is provided with at least one groove, and at least one support draw piece is arranged in the groove.Like this, because body is provided with groove, Cast-in-place concrete can form cross rib in groove, thereby, cast-in-place concrete cored vertical cross stiffness difference significantly reduces, can form two-way hollowcore slab, improve the mechanical property of hollowcore slab greatly, simultaneously, because groove has at least one support draw piece, thereby improved the overall performance of hollow section greatly, reduce the breakage rate in the handling process, thereby reached purpose of the present invention; In addition, hollow section also has the intensity height, makes easy, characteristics such as cost is low, convenient construction and transport, the hollow building cover, roof system, sole plate, body of wall or the hollow bridges that are applicable to various cast-in-situ reinforced concretes or prestressed reinforced concrete are used, and are specially adapted to hollow arch without beam and use.
