Description

The two-way hollow big plate of steel concrete shear connector formula

The utility model structure relates to hollow floor with ribbing, is a kind of two-way hollow big plate of steel concrete shear connector formula of new spatial sheet structure.

In many, high building structure, building (room) lid structure commonly used at present has beam and slab type, rib steel reinforced arch without beam, prestressed slab structure, non-prestressed slabbed construction, and these structures all have the shortcoming that self can't overcome.The beam and slab type building cover structure in the ordinary course of things, the Vierendeel girder depth of section needs 1/10~1/12 of span, thereby structure takes up room greatlyyer, is not easy to the pipe line arrangement in the building, when architecture indoor needs furred ceiling, will take the interior space again.For satisfying interior space requirement, must structurally increase floor height, when floor height is restricted, can only adopt to be not more than the wide wide-flat beam of post and to satisfy rigidity requirement, amount of reinforcement will increase about 25%~40% this moment, and concrete amount will increase by 50%; For the rib steel reinforced building cover structure, the postpone of building pipeline cloth still needs furred ceiling to handle, and is not remarkable to the reduction of building floor height, and the steel concrete amount is also more than the beam and slab type superstructure; The arch without beam span generally about 6 meters, for improving slab column system horizontal force resistant performance and the punching failure that prevents plate, then needs establish cap in the sheet-pile junction, thereby the building implements pipeline still needs furred ceiling, compare with rib steel reinforced, rolled steel dosage increases by 70%, and concrete amount increases by 50%.Prestressed slab need apply prestressed facility, during prestressed reinforcement of tensioning, need take measures to eliminate the obstacle of floor compressive strain, and difficulty of construction is big.

In low-rise building, use a kind of compound floor with ribbing at present, this kind superstructure is actually equivalence and is the groined slab floor behind the plate on mechanical property, because that its rib is is solid, thereby behind the shaping structures, does not partly have value on an empty stomach.

In view of the above-mentioned shortcoming that prior art exists, its purpose of the utility model is to provide a kind of steel concrete shear connector formula two-way hollow big plate.

The two-way hollow big plate of steel concrete shear connector formula of the present utility model is a kind of new spatial sheet structure floor, at the grid intersection point place of upper and lower rib of slab and the formation of upper and lower rib shear connector is set and constitutes.Promptly by upper plate and the last rib that is attached thereto, the shear connector formation that the rib up and down that the intersection point place of following rib and the grid that forms at last rib and following rib is provided with is connected.

This two-way hollow its dead load of big plate is light, and stress performance, anti-seismic performance are good, construction install convenience, and be that flexible division of architectural space provided convenience, the horizontal pipeline of building can pass through in empty stomach, has reduced the structure floor height, is adapted to many, high building structure.

Description of drawings and embodiment:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the open-spandrel sandwich board structural representation of the utility model structure;

Fig. 3 is a bottom surface of the present utility model network schematic diagram;

Fig. 4 is a bottom surface of the present utility model local area network lattice structure schematic diagram;

Among the figure:

The last rib of 1-; Rib under the 2-;

The prefabricated upper plate of 3-; The 4-lower plate;

The prefabricated bed die of the last rib of 5-; 6-shear connector prefab form;

The 7-shear connector.

Referring to Fig. 1~Fig. 4, the two-way hollow big plate of steel concrete shear connector formula of the present utility model is by upper plate (3) and the last rib (1) that is attached thereto, shear connector (7) formation that the rib up and down that the intersection point place of following rib (2) and the grid that forms at last rib (1) and following rib (2) is provided with is connected.

Referring to Fig. 1 and Fig. 2, the following rib (2) of this two-way hollow big plate lower plate (4) of having ined succession, be that the utility model can be by upper plate (3) and the last rib that is attached thereto (1), the shear connector (7) that the rib up and down that the intersection point place of lower plate (4) and following rib (2) that connects with it and the grid that forms at last rib (1) and following rib (2) is provided with is connected constitutes.Also just form open-spandrel sandwich board.Upper plate (3) and go up rib (1) and space that lower plate (4) and following rib (2) are enclosed in, only shear connector (7) is located to solid, remainder is hollow.

Referring to Fig. 3, reflected the grid worker base plate of forming by rib under the bottom surface (2) and shear connector (7) among the figure.

Referring to Fig. 4, lower plate (4) is local plate face, is local area network form base plate thereby constitute the bottom surface.

Detailed process is as follows: cast-in-place lower plate (4) reaches rib (2) down, treat to shelve shear connector cover (6) and prefabricated band floor (3) behind the concrete initial set, the formation secondary waters and is shaped on the rib groove, on the bundle behind the rib steel muscle, the high one-level concrete of casting rib (1) and shear connector (7) promptly forms open-spandrel sandwich board as shown in Figure 2.By shown in Figure 3, cast-in-place rib (2) down, treat to shelve bonding force cover (6) and the prefabricated bed die of last rib (5) or adopt conventional construction formwork behind the concrete initial set, put prefabricated upper plate (3) again, pour into a mould the concrete of going up rib (1) and shear connector (7) then and promptly form the grid type base plate that the bottom surface has only shear connector (7) and following rib (2) to constitute.As shown in Figure 4, if cast-in-place rib (2) and local lower plate (4) down, treat to shelve bonding force cover (6) and the prefabricated bed die of last rib (5) behind the concrete initial set, hand over and put prefabricated upper plate (3), promptly to form the bottom surface be local area network form base plate to the cast concrete of going up rib (1) and shear connector (7) then.

Compared with the prior art, steel reinforced concrete shearing force provided by the utility model The mechanical property of the big plate of key formula bidirectional hollow belongs to three-D space structure, can improve and build Building structure rigidity; Its dead load is light, can save the material on post, wall and basis and use Amount, shock resistance strengthens; The utility model is because building pipeline can pass through on an empty stomach folder In the layer, removed the furred ceiling desired height from, can reduce the building floor height, it is high to reduce building Degree, thus construction timber saved, reduce cost of a building; The utility model structure also For the flexible division of interior construction spacing provides condition, partition wall can adopt light partition wall Or 120 brick walls, both can save the building common brick also can increase the building usable floor area simultaneously.
