A kind of hollow pipe for filling concrete
(1) technical field
The present invention relates to a kind of hollow pipe for filling concrete.
(2) background technology
Advantages such as at present, cast-in-situ concrete hollow floor is owing to have quick construction, and the template loss is little, can realize large bay, cuts off flexibly, and it is little to conduct oneself with dignity are more and more widely used.It becomes pole to be generally hollow thin-wall pipe, as paper tube, pipe of cement etc., its shortcoming is that intensity difference, non-deformability are little, the anti-vibration deformability is poor, for this reason, the application number of applicant application is 99115649.8, name is called the patent of invention of " fibre reinforced hollow thin-wall tube for filling in bar reinforced concrete and manufacture method thereof ", its disclosed hollow thin-wall pipe comprises body, plug, two plugs form a sealed hollow light-wall pipe with the body closed at both ends, have premium properties such as intensity height, resistance to deformation, anti-vibration, and make simple, practical, economic, easy popularization.But it is not firm to be connected between its plug of this hollow thin-wall pipe and the body, the phenomenon that is prone to separation, ftractures or comes off, simultaneously, be applied to cast-in-situ concrete hollow floor after, formed hollowcore slab is unidirectional hollowcore slab, its vertical cross stiffness difference is big, poor seismic behavior.Therefore, develop a kind of novel hollow pipe for filling concrete for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of hollow pipe for filling concrete, it is firm to be connected between its plug and the body, the phenomenon that is not prone to separation, ftractures or comes off, simultaneously, be applied in the cast-in-situ concrete hollow floor, can reduce the vertical cross stiffness difference of superstructure, improve anti-seismic performance.
Solution of the present invention is on the basis of existing technology, comprises body, plug, and two plugs form the hollow section of sealing with the shutoff of body two ends, it is characterized in that having at least one end plug of described hollow section and the tube wall all-in-one-piece plug matching edge that joins.Like this, owing to have at least one end plug of hollow section and the tube wall all-in-one-piece plug matching edge that joins, thereby, be connected firmly the phenomenon that is not prone to separation, ftractures or comes off between plug and the body; Simultaneously, be superimposed with the plug of matching edge, its intensity height, rigidity are big, can play the effect of transverse stiffener, thereby after being applied to cast-in-situ concrete hollow floor, the vertical cross stiffness difference of superstructure can reduce greatly, and anti-seismic performance can improve greatly; In addition, characteristics such as hollow section also has intensity height, resistance to deformation, anti-vibration, manufacturing is easy, cost is low, 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 the cast-in-situ reinforced concrete hollow arch without beam and use.
