Description
(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 after this hollow thin-wall pipe is applied to cast-in-situ concrete hollow floor, formed unidirectional hollowcore slab, its vertical cross stiffness difference is big, poor seismic behavior, and simultaneously, it is not firm to be connected between its plug and the body, the phenomenon that is prone to separation, ftractures or comes off.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, be applied in the cast-in-situ concrete hollow floor, can reduce the vertical cross stiffness difference of superstructure, improve anti-seismic performance, simultaneously, it is firm to be connected between its plug and the body, the phenomenon that is not prone to separation, ftractures or comes off.
Solution of the present invention is on the basis of existing technology, comprise body and plug, two plugs form the body shutoff hollow section of sealing, it is characterized in that at least one plug of described hollow section sinks to formation pipe end pelvic cavity in the body, Intrapelvic plug is provided with overlapping layers, and reinforce in the body and the reinforce in the plug are anchored in the overlapping layers simultaneously.Like this, form the pipe end pelvic cavity in the body because plug sinks to, in being applied to cast-in-situ concrete hollow floor after, Cast-in-place concrete enters in the pipe end pelvic cavity, can form the horizontal stiffening rib compound with plug, thereby, the vertical cross stiffness difference of superstructure reduces greatly, and anti-seismic performance improves; Simultaneously, because Intrapelvic plug is provided with overlapping layers, reinforce in the body and the reinforce in the plug are anchored in the overlapping layers simultaneously, thereby, be connected firmly the phenomenon that is not prone to separation, ftractures or comes off between plug and the body; 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.
