Abstract
The present invention relates to a light tube for filling cast-in-situ steel reinforced concrete, which comprises a tube body (1) which is a corrugated tube body and is characterized in that the corrugated tube body (1) is provided with at least one convex module (2). Due to the fact that the convex module (2) extends on the tube body (1), and the concrete in a floor (roof) is further scraped out, the concrete consumption is small, the self weight is light and the shock resistance is high. The longitudinal stiffness is relatively weakened, and the difference of the bi-directional stiffness is correspondingly decreased, and thereby, the goal of the present invention is reached. Simultaneously, the light tube also has the characteristics of high strength, deformation resistance, high shock resistance, easy construction and transportation, etc. The present invention is suitable for floors, roofs, foundation slabs, walls and open web bridges which are respectively made of cast-in-situ concrete, and is especially suitable for hollow girderless floors made of cast-in-situ reinforced concrete.
Description
(1) technical field
The present invention relates to a kind of cast-in-place reinforced concrete filling light pipe.
(2) background technology
At present, in the prior art, it is permanent core that cast-in-situ hollow floor plate becomes pole, as paper tube, plastic pipe, metal bellows, core light material etc.These tubular core molds or member are mainly considered the concrete of finding time, and reduce floor weight.As metal bellows, it is to adopt the metal coiling and molding, has the intensity height, resistance to deformation, the anti-vibration performance is good, advantages such as convenient construction and transport, but after being applied to cast-in-situ hollow building roof, because the tubulose concrete of the wavy metal tube hub of building roof of reinforcing bar concrete is found time, along pipe the Cast-in-place concrete rib arranged vertically, and laterally found time by the wavy metal pipe component owing to steel bar concrete, thereby the bigger situation of cast-in-place hollow slab two direction rigidity great disparities appearred, and become the cast-in-situ reinforced concrete hollow one-way slabs, exist the steel bar concrete consumption big, from great, poor seismic behavior, the big deficiency that waits of two-way stiffness difference.Therefore, develop a kind of novel cast-in-place reinforced concrete filling light pipe for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of cast-in-place reinforced concrete filling light pipe, be applied in hollow-core construction building (room) lid, building (room) lid have the concrete consumption little, from heavy and light, characteristics such as anti-seismic performance is good, two-way stiffness difference is little, simultaneously, light pipe is produced more convenient, and cost of production is lower.
Solution of the present invention is on the basis of existing technology, comprises body, and body is a bellows body, it is characterized in that having on bellows body the module of at least one protrusion, and module is the ripple module.Like this, owing to be extended with the module of protrusion on body, the concrete in building (room) lid is further emptied, thus the concrete consumption is little, good from heavy and light, anti-seismic performance, longitudinal rigidity weakens relatively, corresponding two-way stiffness difference reduces, thereby has reached purpose of the present invention, simultaneously, because module is the ripple module, with bellows body be same type of material, thereby light pipe produces more conveniently, cost of production is lower; In addition, characteristics such as light pipe also has the intensity height, resistance to deformation is big, anti-seismic performance good, convenient construction and transport, be applicable in steel bar reinforced hollow concrete roof cast-in-situs, roof system, sole plate, body of wall, the hollow bridges and use, be particularly useful for the cast-in-situ reinforced concrete hollow arch without beam and use.
