Abstract
The utility model provides a novel cast-in-place hollow floor slab. The hollow floor slab internally comprises a rebar net framework, a trapezoidal internal mold pipe and an elastic gasket. The novel cast-in-place hollow floor slab is characterized in that the hollow floor slab is formed by casting concrete in place, and an inverted trapezoidal rib beam is arranged in the hollow floor slab. The rebar net framework comprises a lower tensile reinforcement, an upper compression reinforcement, a ribbed beam reinforcement and a constructional reinforcement, and various reinforcements are bound and fixedly connected through steel wires. The trapezoidal internal mold pipe is a high-strength thin-wall pipe, the upper surface and the bottom of the trapezoidal internal mold pipe are respectively provided with elastic gaskets, and the elastic gaskets are fixedly connected with the rebar net framework. When a construction structure column net span or a floor slab structure load is large, part of the ribbed beam reinforcement can be arranged into a prestressed reinforcement in the inverted trapezoidal rib beam so as to fully serve the performance characteristics that upper concrete of the inverted trapezoidal rib beam is pressed and the lower ribbed beam reinforcement is pulled.
Description
Technical field
The utility model relates to building engineering structure technical field, is specifically related to a kind of novel cast-in-situ hollow floor plate.
Background technology
Reinforced concrete hollow floor has the features such as concrete feed consumption is few, floor is lightweight, and cost is low.But the high-strength thin-wall pipe cast-in-situ hollow floor plate structure conventionally adopting, internal mold pipe is round-shaped often, internal mold pipe location and installation while being unfavorable on the one hand form work engineering construction, the I shape girt strip structure that its interval forms simultaneously, compare with inverted trapezoidal girt strip structure, the upper portion pressurized district concrete section area relatively concrete section area of tensile region, little ， bottom is relatively large, is unfavorable for giving full play to of large span cassette ceiling structural bearing performance.During for building structure post net span or the larger instructions for use of floor slab structure load, adopt trapezoidal internal mold pipe, by its interval, form inverted trapezoidal girt strip structure, can effectively strengthen the supporting capacity of large span cassette ceiling internal-rib girder construction.
Utility model content
The purpose of this utility model is to provide a kind of novel cast-in-situ hollow floor plate, can effectively increase span and the standard width of a room in an old-style house of floor slab structure, during for building structure post net span or the larger instructions for use of floor slab structure load, can significantly promote architectural space Integrated using efficiency.
For achieving the above object, the technical solution adopted in the utility model is: a kind of novel cast-in-situ hollow floor plate, in cassette ceiling, comprise steel mesh reinforcement skeleton, trapezoidal internal mold pipe and elastomeric pad, it is characterized in that: described cassette ceiling is made by concrete cast-in-situ construction, is provided with inverted trapezoidal girt strip in cassette ceiling; Steel mesh reinforcement skeleton comprises bottom tensile reinforcement, upper portion pressurized reinforcing bar, and girt strip reinforcing bar and distributing bar, various reinforcing bars adopt steel wire lashing to be connected and fixed; Trapezoidal internal mold pipe is high-strength thin-wall pipe, above be respectively equipped with elastomeric pad with going to the bottom, elastomeric pad is fixedly connected with steel mesh reinforcement skeleton; At building structure post net span or floor slab structure load when larger, in inverted trapezoidal girt strip, also can be set to prestressed reinforcement by part girt strip reinforcing bar, to have given play to more fully the performance characteristics of inverted trapezoidal girt strip top concrete compression, bottom girt strip reinforcing bar tension.
As preferably, described internal mold pipe can arrange surperficial separation layer together before location and installation, this separation layer be one deck firm without seam integral waterproofing film.
Use the utility model, described trapezoidal internal mold pipe need support the use with elastomeric pad member, and elastomeric pad is divided into short elastomeric pad and long elastomeric pad, be respectively used to trapezoidal internal mold pipe above with go to the bottom.Adopt steel wire lashing mode that the upper portion pressurized reinforcing bar in elastomeric pad and cage of reinforcement and bottom tensile reinforcement location is fixing, the high-strength thin-wall pipe that trapezoidal internal mold pipe is used is fixedly placed between elastomeric pad, guarantee that trapezoidal internal mold pipe can not float, be shifted in floor concrete casting work progress, also avoided trapezoidal internal mold pipe directly to contact with steel mesh reinforcement skeleton and produce damaged.
Use the utility model, can effectively increase the supporting capacity of cast-in-situ hollow floor plate structural ribs beam, significantly promote building structure spatial synthesis service efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 is cassette ceiling, 2 is trapezoidal internal mold pipe, and 3 is inverted trapezoidal girt strip, and 4 is bottom tensile reinforcement, and 5 is long elastomeric pad, and 6 is prestressed reinforcement, and 7 is girt strip reinforcing bar, and 8 is top tensile reinforcement, and 9 is distributing bar, and 10 is short elastomeric pad.
The specific embodiment
It is by reference to the accompanying drawings, existing that the utility model is described in further detail.
Consult Fig. 1, a kind of novel cast-in-situ hollow floor plate, comprises steel mesh reinforcement skeleton, trapezoidal internal mold pipe 2 and elastomeric pad in cassette ceiling 1, it is characterized in that: described cassette ceiling 1 is made by concrete cast-in-situ construction, is provided with inverted trapezoidal girt strip 3 in cassette ceiling 1; Steel mesh reinforcement skeleton comprises bottom tensile reinforcement 4, upper portion pressurized reinforcing bar 8, and girt strip reinforcing bar 7 and distributing bar 9, various reinforcing bars adopt steel wire lashing to be connected and fixed; Trapezoidal internal mold pipe 2 is high-strength thin-wall pipe, above be respectively equipped with elastomeric pad with going to the bottom, elastomeric pad is divided into long elastomeric pad 5 and short elastomeric pad 10, elastomeric pad is fixedly connected with steel mesh reinforcement skeleton; At building structure post net span or floor slab structure load when larger, in inverted trapezoidal girt strip 3, also part girt strip reinforcing bar 7 can be set to prestressed reinforcement 6, to have given play to more fully the performance characteristics of inverted trapezoidal girt strip 3 top concrete compressions, bottom girt strip reinforcing bar tension.
During concrete enforcement, the high-strength thin-wall pipe that trapezoidal internal mold pipe is used also should require surface smoothing, flawless, hole, burr etc., and its plug at end part is firm; Above trapezoidal internal mold pipe, be respectively equipped with elastomeric pad with going to the bottom, guarantee that trapezoidal internal mold pipe does not produce breakage in template installation and cast-in-situ hollow floor plate concrete pouring construction process.
