Abstract
The utility model discloses a big-thickness hollow floorslab of a thin-wall inner module, which comprises a totally-sealed pipe-shaped core pipe, a mat reinforcement and pouring concrete, wherein theupper portion and the lower portion of the core pipe are respectively provided with the mat reinforcement, a pressure pipe steel rib is attached and wounded on each core pipe, a row of vertical anti-floating steel ribs are arranged cross each 2-4 core pipes, and pouring concrete is filled among the core pipes, the mat reinforcement and the pressure pipe steel ribs and on the upper mat reinforcement. The big-thickness hollow floorslab of the thin-wall inner module is a double-layer reinforcing bar structure, the core pipe is arranged in the middle of concrete, thereby forming a hollow structure, and becoming a permanent core module, and the structure solves the problem of fixing and floating of concrete during the casting process. The big-thickness hollow floorslab has fast construction speed, convenient installation and excellent thermal-insulation and sound-proof property, can effectively lower dead weight, correspondingly reduces main girders, posts, walls and base load for supporting floorslabs, and greatly reduces the quantity of structural component reinforcing bars.
Description
Technical field
The utility model relates to a kind of cassette ceiling, refers in particular to thin-wall internal-mould large-thickness hollow floor plate.
Background technology
Along with the continuous development of Building technology, new technology, new technology also constantly adapt to the requirement that construction house span is big, the space big, separate aspects such as flexible and antidetonation.Cast-in-place concrete hollow floor slab is one of technology wherein.Major diameter single tube cassette ceiling construction technology is novel succinct, and speed of application is fast, and insulation, sound insulation value are good, can effectively reduce dead load, and seismic forces is weakened.Compare with ordinary concrete floor slab structure system, cast-in-place hollow concrete flat slab construction system is according to the different building total costs that reduce with load of span, and application prospect is boundless.But, because core pipe and reinforcement structure in the cassette ceiling are unreasonable, at present when cast-in-place concrete hollow floor slab, the core pipe be subjected to easily the shake come-up and about drift, this has brought hidden danger to construction quality.Developing a kind of thin-wall internal-mould cassette ceiling that is easy to the science construction rational in infrastructure is necessary.
The utility model content
The technical problems to be solved in the utility model provides a kind of thin-wall internal-mould large-thickness hollow floor plate, this thin-wall internal-mould large-thickness hollow floor plate construction technology is simple, easy for installation, can effectively reduce dead load, seismic forces is weakened, support the also corresponding minimizing of girder, post, wall and foundation load of floor, and significantly reduce the structural element quantity of reinforcement.Compare with ordinary concrete floor slab structure system, adopt thin-wall internal-mould large-thickness hollow floor plate to reduce the building total cost, and solved the above-mentioned fixing and come-up problem of core pipe when cast-in-place according to span is different with load.
The technical problems to be solved in the utility model is realized by following scheme: thin-wall internal-mould large-thickness hollow floor plate, comprise that one deck is core pipe, the steel mesh reinforcement of totally-enclosed pipe shape, it is characterized in that: the upper and lower of described one deck core pipe respectively is provided with steel mesh reinforcement, every core pipe tightens and has posted a pressure pipe reinforcing bar, every interval 2-4 core pipe promptly is provided with the vertical anti-floating reinforcing bar of a row, the top concreting of all filling of between core pipe, steel mesh reinforcement and the pressure pipe reinforcing bar and top steel mesh reinforcement.
The utility model also comprises following scheme: the upper and lower side of described anti-floating reinforcing bar is fixedlyed connected with described steel mesh reinforcement up and down respectively.Fixedly connected with described steel mesh reinforcement down in the two ends of described pressure pipe reinforcing bar.
The utility model has the advantages that: thin-wall internal-mould large-thickness hollow floor plate is double-deck reinforcement structure, has solved the come-up problem of core pipe in concreting process.Bigbore core pipe is positioned at concrete centre position, forms hollow structure, becomes permanent mandrel.Thin-wall internal-mould large-thickness hollow floor plate has solved the fixing and come-up problem of core pipe in concreting process.As long as core pipe position upper and lower bound is controlled well, floor floor iron and form bracing system (flitch or steel pipe) fixation just can be controlled the relative position of core pipe in the levels arrangement of reinforcement effectively, guarantees structural performance.The present invention's succinct speed of constructing is fast, easy for installation, and insulation, sound insulation value are good, can effectively reduce dead load, and seismic forces is weakened, and support the also corresponding minimizing of girder, post, wall and foundation load of floor, have significantly reduced structure reinforced component amount.
Description of drawings
Fig. 1 is the sectional drawing of thin-wall internal-mould large-thickness hollow floor plate
The specific embodiment
Below in conjunction with accompanying drawing 1 for an embodiment: as shown in Figure 1, this thin-wall internal-mould large-thickness hollow floor plate is double-deck reinforcement structure, and core pipe 1 diameter that one deck is totally-enclosed pipe shape is 450cm, is embedded in the concrete structure centre position, form hollow structure, become permanent mandrel.The upper and lower of core pipe 1 respectively is provided with steel mesh reinforcement 2,3.Every core pipe 1 tightens and has posted a pressure pipe reinforcing bar 4, fixedlys connected with following steel mesh reinforcement 3 in the two ends of pressure pipe reinforcing bar 4.Two the core pipes 1 in every interval promptly are provided with the vertical anti-floating reinforcing bar 5 of a row, and the upper and lower side of anti-floating reinforcing bar 5 is fixedlyed connected with steel mesh reinforcement 2,3 up and down respectively.
As shown in Figure 1, the top concreting 6 of all filling of between core pipe 1, steel mesh reinforcement 2,3 and the pressure pipe reinforcing bar 4 and top steel mesh reinforcement 2.Core pipe 1 is made by cement-base composite material, and the surface is little rough, can bear gently stepping on of constructor, has small water imbibition.Therefore form one with concrete 6 after concrete 6 final set, the moisture that core pipe 1 absorbs before concrete 6 final set can slowly be absorbed by concrete 6 after concrete 6 is built moulding, can not cause the inside configuration water.
Claims (3)
1, thin-wall internal-mould large-thickness hollow floor plate, comprise that one deck is core pipe, the steel mesh reinforcement of totally-enclosed pipe shape, it is characterized in that: the upper and lower of described one deck core pipe respectively is provided with steel mesh reinforcement, every core pipe tightens and has posted a pressure pipe reinforcing bar, every interval 2-4 core pipe promptly is provided with the vertical anti-floating reinforcing bar of a row, the top concreting of all filling of between core pipe, steel mesh reinforcement and the pressure pipe reinforcing bar and top steel mesh reinforcement.
