Description
(1) technical field
The present invention relates to a kind of cast-in-situ reinforcing steel bar concrete hollow slab.
(2) background technology
At present, cast-in-situ floor is saved the concrete consumption for reducing deadweight, usually some is filled out core material and adds in the concrete, as perlite block, polyphenyl foam, thin-wall tube member etc.As the patent No. is ZL99232921.3, name is called " cast-in-place reinforced concrete filling thin wall cylinder " utility model patent, it discloses a kind of thin-wall tube member, comprise body, plug, two plugs form an enclosed cavity with the horniness thin-walled tube closed at both ends, the cross section of described horniness thin-walled tube and plug shape can be circle, square, trapezoidal or other are special-shaped, described horniness thin-walled tube and plug can be used organic material, inorganic material, organic and inorganic composite materials manufacturing, be applied to cast-in-situ hollow building roof, can effectively save the concrete consumption, reduce dead load, but also have convenient construction and transport, fast, it is little to absorb water, advantages such as sound insulation value is good.And for example the patent No. is that ZL99249755.8, name are called " cast-in-place reinforced concrete filling fiber reinforcement type thin wall cylinder " utility model patent, it also comprises body, plug, two plugs form an enclosed cavity with the horniness thin-walled tube closed at both ends, this hard thin-wall tube wall is composited by carcass and cementitious materials, carcass can be glass fiber or carbon fiber or organic fiber or nonwoven or fibrous braid, and cementitious materials can be the mixture of cement or organic resin or cement, filler, Admixture, fiber.Because it is good to have adopted composite construction, tube wall to have an intensity height, resistance to deformation, anti-vibration performance, advantages such as convenient construction and transport.This light-wall pipe is applied to cast-in-situ reinforcing steel bar concrete hollow slab, its light-wall pipe is wrapped up in and is contained in the cast-in-situ reinforced concrete; light-wall pipe longitudinally is the Cast-in-place concrete longitudinal rib each other; but such light-wall pipe all is that elder generation makes body, plug, again body and plug gluing is become whole; in carrying and work progress; often be prone to the phenomenon that plug separates, comes off with body, and influence the quality and the follow-up construction of hollowcore slab, increased the construction cost of hollowcore slab.Therefore, develop a kind of novel cast-in-situ reinforcing steel bar concrete hollow slab 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-situ reinforcing steel bar concrete hollow slab, have characteristics such as construction quality is good, construction cost is low.
Solution of the present invention is on the basis of existing technology, include steel bar concrete, light-wall pipe; light-wall pipe is wrapped up in and is contained in the Cast-in-place concrete; light-wall pipe is made of body and plug; vertically be set to the Cast-in-place concrete longitudinal rib; it is characterized in that socketing part between body and the plug is connected, the termination that sockets part is fixed in body or the plug along light-wall pipe between the light-wall pipe.Like this, socketing part between body and the plug is connected, the termination that sockets part is fixed in body or the plug, thereby the good integrity of light-wall pipe member, in the work progress of hollowcore slab, not easily separated between plug and the body, come off, thereby improved the construction quality of hollowcore slab greatly, accelerate speed of application, reduced construction cost, thereby reached purpose of the present invention; Simultaneously, cast-in-situ reinforcing steel bar concrete hollow slab also has characteristics such as simple in structure, that intensity is high, construction is easy, is applicable to the structure of various Cast-in-place Concrete Building Floor, roof system, body of wall, sole plate and road and bridge engineering, is specially adapted to hollow arch without beam.
