Abstract
The utility model relates to a large-span prestressed hollow laminated slab, which comprises a prefabricated slab and an in-situ concrete slab. A reinforcement girder which can enhance the integrated stiffness and the bonding power between the prefabricated slab and the in-situ concrete slab, and a hollow tube is fixedly connected between the in-situ concrete slab and the reinforcement girder. Because the reinforcement girder is added in the prefabricated slab, and the prestress is applied, the structural stiffness is greatly enhanced, simultaneously the reinforcement girder can also enhance the bonding power between the prefabricated slab and the in-situ concrete slab, the structure is more reliable, and the hollow tube added to the in-situ concrete slab can reduce the dead weight.
Description
Technical field:
The utility model belongs to technical field of civil engineering, especially relates to a kind of hollow superimposed sheet.
Background technology:
Reinforced concrete floor is the important member of civil engineering, and the material of consumption is many, long construction period.Main armored concrete slab has three kinds: a kind of cast-in-place plate, and a kind of is precast plate, a kind of is superimposed sheet.Cast-in-place slab integral and anti-seismic performance are good, but need a large amount of templates, time-consuming taking a lot of work, and precast plate does not need template, and speed of application is fast, but the globality of structure and shock resistance are bad; Superimposed sheet is exactly the characteristics that combine cast-in-place plate and two kinds of plates of precast plate, and floor is divided into two parts, and a part is made precast plate,, waters one deck cast-in-situ concrete and pre-erection in the above again and bears load jointly as template with precast plate.And the pre-erection ratio of rigidity of superimposed sheet is less at present, can not be adapted to longspan structure, and pre-erection is unreliable with being connected of cast-in-place part, and dead load is big, waste material.
Summary of the invention:
Technical problem to be solved in the utility model aims to provide a kind of superimposed sheet that is applicable to large span, improves the rigidity of superimposed sheet and the adhesion stress between the new-old concrete, to overcome the defective that background technology exists.
For solving the problems of the technologies described above, the utility model provides a kind of large-span prestressed hollow superimposed sheet, comprise precast plate, cast-in-place plate, it is characterized in that: in precast plate, be embedded with the steel bar girder that can improve adhesion stress between whole stiffness and precast plate and the cast-in-place plate, in cast-in-place plate, be fixedly connected with hollow section with steel bar girder.
The utility model is owing to added steel bar girder and applied prestressing force in precast plate, improved the rigidity of structure of precast plate greatly, steel bar girder can improve the adhesion stress between precast plate and the cast-in-place plate again simultaneously, makes structure more reliable, adds hollow section to alleviate deadweight in cast-in-place plate.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
With reference to accompanying drawing, the utility model comprises precast plate 4, cast-in-place plate 5, is embedded with the steel bar girder 2 that can improve adhesion stress between whole stiffness and precast plate and the cast-in-place plate in precast plate 4, is fixedly connected with hollow section 3 with steel bar girder 2 in cast-in-place plate 5.
During making, the prestressed reinforcement 1 in the stretch-draw precast plate 4 at first, fixedly put into steel bar girder 2 with prestressed reinforcement 1 then, build precast plate 4 concrete and maintenance to design strength, again precast plate 4 is installed to design attitude, put into hollow section 3 and fixing, build cast-in-place plate 5 concrete and maintenance, promptly make large-span prestressed hollow superimposed sheet to design strength with steel bar girder 2.
