The longitudinal stiffness is relatively weakened, and simultaneously, due to the fact that the light pipe (2) is provided with the transverse groove (4), the cast-in-situ concrete ribs (5) can be formed by the cast-in-situ concrete, which further enhances the transverse stiffness of the floor (roof) and decreases the bi-directional stiffness difference of the floor (roof).
Description
(1) technical field
The present invention relates to a kind of cast-in-situ reinforced concrete superstructure.
(2) background technology
At present, the most of precast hollow slab that adopts of the building of brick mix structure and frame construction is as floor structure, and this floor structure has advantages such as speed of application is fast, cost is low.But, only use the cement mortar joint filling, thereby globality is poor, is unfavorable for antidetonation, and phenomenons such as slit cracking, infiltration often occur owing to firmly do not link between adjacent two precast hollow slabs.For addressing the above problem, a lot of building have adopted the method for Cast-in-place Concrete Building Floor (solid, hollow), have solved problems such as antidetonation, cracking, infiltration preferably, but this class floor construction relative difficult, and cost is higher relatively.Along with Building technology and expanding economy, the quality of building to be had higher requirement, most Cast-in-place Concrete Building Floor has all adopted the cast-in-situ concrete hollow building
Technology.And the one-tenth pole in the cast-in-situ hollow building roof is permanent core, as paper tube, plastic pipe metal bellows, core light material, horniness thin-walled tube etc.These tubular core molds or member are mainly considered the concrete of finding time, and alleviate superstructure weight.As the patent No. by applicant's application is that ZL99249775.8, name are called the utility model patent of " cast-in-place reinforced concrete filling fiber reinforcement type thin wall cylinder ", 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, 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 cement or organic resin or is the mixture of cement, filler, Admixture, fiber.This kind pipe has advantages such as intensity height, resistance to deformation, anti-vibration performance are good, convenient construction and transport.During application, this light pipe is embedded in the steel bar concrete, can forms cast-in-situ concrete hollow floor.And for example the patent No. of applicant's application is that ZL99232922.1, name are called " thin-wall hollow roof in-situ deposited with concrete ", it is made up of steel bar concrete and thin wall cylinder noggin piece; the thin wall cylinder noggin piece is embedded in the steel bar concrete; described thin-wall tube member is made up of horniness thin-walled tube and plug, and two plugs form an enclosed cavity with the horniness thin-walled tube closed at both ends.This class steel bar reinforced hollow concrete roof cast-in-situs; because its tubulose concrete of filling the light pipe center of usefulness 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, thereby the bigger situation of cast-in-situ reinforcing steel bar concrete hollow slab two direction rigidity great disparities has 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-situ reinforced concrete superstructure for being badly in need of.
(3) summary of the invention
