Abstract

The utility model relates to a prestressed or non prestressed laminated floor slab, which is suitable for building structures and overcomes the shortages that the integrity and the shock resistance are poor in the traditional prefabricated prestressed hollow floor slab, the work efficiency and the construction speed of cast-in-situ floor slabs are low, a common laminated floor slab is also required to be provided with a temporary support, etc. A full new floor slab structure which uses a prefabricated hollow slab as a laminated slab and relieves the temporary support is adopted. The rigidity and the strength of the prestressed or non prestressed laminated floor slab are better than that of the present flat slab type laminated slab. A temporary support is not required, and therefore, the construction speed is high. The utility model which raises the level of commercial construction, is favorable to civilized construction, raises the integrity of floor slabs and has favorable shock resistance can be widely popularized and used in seismic areas and non-seismic areas.

Description

A kind of stress or non-stress laminated floor slab that gives of giving

This practicality is for relating to a kind of laminated floor slab, particularly relate to a kind of be applicable to building structure give stress or the non-stress laminated floor slab that gives.

As everyone knows, be used for the floor slab structure of industry and civilian construction now, it is relatively poor that the use tradition that the has system of giving is given its anti-seismic performance of stress cassette ceiling, is easy to generate vertical straight joint cracking; The use overall performance that has is cast-in-situ floor preferably, and need prop up form removal during construction and support temporarily influences programming; And still interim support must be set when adopting the construction of general laminated floor slab.

The purpose of this utility model is in order to overcome the shortcoming of above several floor slab structures, a kind of novel stress or non-stress superimposed sheet that gives of giving is provided, and combining the traditional system of giving cassette ceiling does not have the installation rate of support fast and cast-in-situ floor globality and the good advantage of anti-seismic performance.

The purpose of this utility model is to realize like this, that is: a kind of stress or non-stress laminated floor slab that gives of giving, form by the overlapping layers that gives the system superimposed sheet and give on the system laminated floor slab, it is characterized in that the aforesaid system superimposed sheet that gives for giving the system hollowcore slab, it gives the system hollowcore slab interim support need not be set when constructing at the scene.

For globality and the shear behavior that improves laminated floor slab, aforesaid give system hollowcore slab its cross section be hollow both sides have choose plate as

Shape, at the construction field (site) with overlapping layers with have the system hollowcore slab superimposed back of giving of choosing plate and constitute one

Shape laminated floor slab structure is first kind of laminated floor slab structure.

With aforementioned identical reason, described give system hollowcore slab its cross section be hollow both sides have choose plate and middle part have frid as

Shape, overlapping layers with have the system hollowcore slab superimposed back of giving of choosing plate and middle part frid and constitute one

Shape laminated floor slab structure is second kind of laminated floor slab structure.

With aforementioned identical reason, described give system hollowcore slab its cross section be hollow both sides have choose plate as

Shape, overlapping layers with have the system hollowcore slab superimposed back of giving of choosing plate and constitute one Shape laminated floor slab structure is the third laminated floor slab structure.

Shape laminated floor slab structure is the 4th kind of laminated floor slab structure.

The utility model compared with prior art has following good effect:

(1), rigidity and intensity all is better than present plate stack plywood, the construction overlapping layers need not add interim support system, labor and material saving speed is fast.

(2), improved the factorial construction degree, help civilized construction.

(3), having overcome tradition, to give system hollowcore slab anti-seismic performance relatively poor and be easy to generate the disadvantage in vertical elongated crack, the utility model good integrity has good seismic resistance.

Below in conjunction with accompanying drawing the novel concrete structure of this reality is further described.

Fig. 2 is second kind of laminated floor slab structure schematic cross-sectional view of the present utility model.

Fig. 3 is the third laminated floor slab structure schematic cross-sectional view of the present utility model.

Fig. 4 is the 4th a kind of laminated floor slab structure schematic cross-sectional view of the present utility model.

Fig. 5 is the 1-1 generalized section, is limit bearing and intermediate support structural representation.

1 is superimposed sheet shown in the figure, also is and gives the system hollowcore slab, and 2 is the elongated circle of superimposed sheet, ellipse or other as shape hole such as square, and 3 is overlapping layers, and 10 is the limit bearing, and 11 is intermediate support.The length of superimposed sheet of the present utility model is that 1500MM-7500MM, plate width are that the height of 400MM-3000MM, plate is 80MM-180MM, and the muscle of should advocating that gives of superimposed sheet disposes distribution reinforcement simultaneously.4 to be that intermediate channel is local link to each other shown in the figure, when being used for the hollowcore slab broad to improve the lateral stiffness of plate.

Embodiment 1 is: its superimposed sheet of a kind of laminated floor slab is that 4 pore areas have the system of giving hollowcore slab such as the Fig. 1 that chooses plate, superimposed sheet length is the wide 700MM of being of 4200MM, plate, the high 100MM-120MM of being, overlapping layers is furnished with reinforcing bar in length and breadth, and its transverse reinforcement spacing is 200MM-300MM.The laminated floor slab of being made up of superimposed sheet and overlapping layers is shelved on limit bearing 10 and the intermediate support 11 as shown in Figure 5.

Embodiment 2 is: its superimposed sheet of a kind of laminated floor slab is that three holes add three pore areas and have the stress that gives of choosing plate and frid to give the system hollowcore slab, superimposed sheet length is the wide 1200MM of being of 4200MM, plate, highly is will 4 make the intermediate channel upper plate have 2 to 5 places to be connected for improving lateral stiffness during the hollowcore slab broad by 100MM-120MM as shown in Figure 2.

Embodiment 3 is: its superimposed sheet of a kind of laminated floor slab is that 4 pore areas have the stress that gives of choosing plate to give system hollowcore slab such as Fig. 3, superimposed sheet length is the wide 700MM of being of 3600MM, plate, it is 50MM-150MM that every side is chosen width, highly for 120MM, its superimposed sheet is except should advocate muscle and distribution bar are given in the bottom, and it is that arrangement of reinforcement that 150MM-300MM non-gives the vertical and horizontal reinforcing bar of stress and upper face and lower face stretches out all around that plate is outer to be connected with plate in order to plate that its upper board face also is furnished with spacing.The equal configuration reinforcement in overlapping layers upper-layer configured reinforcing bar or the upper and lower.

Embodiment 4 is: its superimposed sheet of a kind of laminated floor slab is that three holes add three pore areas and have the stress that gives of choosing plate and frid to give the system hollowcore slab, superimposed sheet length is that 3600MM, plate are wide for 2000MM, highly be 120MM, its superimposed sheet is except should advocate muscle and distribution bar are given in the bottom, and its upper board face arrangement of reinforcement is also as embodiment 3.Overlapping layers is with embodiment 3.

When above embodiment adopted the bi-steel of terraced framework when the bottom master's muscle in the superimposed sheet, superimposed sheet was that ordinary concrete is the non-stress reinforced concrete structure that gives.Embodiment 1～4 all can add vertical shear reinforcement as superimposed sheet in addition.
