Abstract
A kind of shear wall structure floor reinforcing connection structure, belong to building engineering field, it is characterized in that pasting several carbon cloths along floor long span direction in floor slab bottoms, along short across the direction setting girder steel of floor, girder steel is placed in below carbon cloth and links into an integrated entity with shear wall.Girder steel constitutes whole common stress with shear wall, for resisting the deflection deformation of floor；Carbon cloth and girder steel collective effect greatly improve floor bearing capacity, while without increasing floor dead weight.The utility model has the advantages that convenient, strong applicability of constructing.
Description
Technical field
The utility model is related to a kind of shear wall structure floors to reinforce connection structure, be related to architectural engineering transformation field.
Background technology
China's existing building area is about 40,000,000,000 square metres, wherein there are about 13,000,000,000 square metres or will enter repair
Phase, from another perspective, China are stepping into the peak period of an existing building strengthening reconstruction.By to existing structure into
Row strengthening reconstruction, can meet Some Enterprises plant retrofit needs, can be to the peace that is retained in architecture construction design management
Full hidden danger made up, can improve the bearing capacity of existing building, extends building service life.Often have in practice in engineering and changes
Become the case where existing structure uses function, such as office is changed to warehouse use, office is changed to books storage room etc.,
Floow load is significantly increased in the case of these, and the requirement reinforced to floor is stringenter.
Currently used floor reinforcement means has：Reinforcement method of enlarging section, affixing steel plate reinforcement method and stickup fiber reinforcement
The methods of plastic consolidation method.But all there is certain defect in these types of method, reinforcement method of enlarging section can reduce building headroom；It is viscous
Sticking steel plate method for strengthening is more demanding to technique for sticking；The adhesive material fire resistance pasted in fibre reinforced plastics method for strengthening is poor.
The utility model provides a kind of new approaches, that is, uses girder steel and carbon cloth collective effect, girder steel uses H profile steel, with shear wall
It is connected as one, then can make shear wall to undertake part floow load, while girder steel height should be controlled cannot to influence space net
Height, and fire proofing material is smeared on carbon cloth.The utility model combines the advantages of carbon cloth and shaped steel, while making shearing
Wall undertakes girder steel dead weight, does not increase while improving bearing capacity of floor slab floor dead weight, it is safe to greatly improve structure
Property.
Utility model content
The utility model aims to solve the problem that the problem of shear wall structure bearing capacity of floor slab deficiency, provides a kind of shear wall structure building
Plate reinforces connection structure, while improving bearing capacity of floor slab, does not increase floor dead weight, so that it is guaranteed that floor and overall structure
Safety.
The technical solution of the utility model：A kind of shear wall structure floor reinforcing connection structure, it is characterized in that in shear wall
The floor slab bottoms of structure paste several carbon cloths along long span direction, and the carbon cloth is pasted onto using resinae adhesives
Floor slab bottoms；Along short across direction arrangement girder steel, the girder steel is close to floor slab bottoms and is arranged in the lower section of carbon cloth；In girder steel
Both ends welding steel, the plate size is more than girder steel section, bolt connecting hole is set in steel plate, by high-strength bolt by steel
Beam is linked together with the pre embedded bolt in shear wall.
In above-mentioned technical proposal, fire proofing material is smeared on the carbon cloth.
In above-mentioned technical proposal, the girder steel is made of H profile steel material, and girder steel length is the short span length's degree of floor, height
Space headroom is not influenced, is welded square steel plate at girder steel both ends, is used for the connection of girder steel and shear wall.
The utility model has the following advantages：The utility model can resist the deflection deformation of floor, can also reduce building
Plate generates influence of the crack to structure.While improving bearing capacity of floor slab, since girder steel is to be directly connected to shear wall and carbon
Fiber cloth lighter weight substantially increases the safety of structure so will not increase floor dead weight substantially.

Specific implementation mode
In conjunction with attached drawing, specific embodiment of the present utility model is described further.
Shown in Fig. 1, Fig. 2, Fig. 3, a kind of shear wall structure floor reinforcing connection structure, it is characterized in that in shear wall structure
Several carbon cloths 2 are pasted in the bottom of floor 1 along floor long span direction with resin, and fire proofing material is smeared on carbon cloth 2；Along building
Short across the direction arrangement girder steel 3 of plate, the girder steel 3 are close to floor slab bottoms and are arranged in the lower section of carbon cloth；At the both ends of girder steel 3
Equal welding steel 4,4 size of the steel plate are more than girder steel section, set bolt connecting hole on the steel plate, and high-strength bolt 5 is by steel plate 4
It is linked together with the pre embedded bolt 6 in shear wall 7.
Pre embedded bolt 6 is fastenedly connected across steel plate 4 by nut.
Girder steel length is the short span length's degree of floor, and height does not influence space headroom, welds square steel plate at girder steel both ends, uses
In the connection of girder steel and shear wall.
Although the embodiments of the present invention has been shown and described above, it is to be understood that above-described embodiment is example
Property, it should not be understood as limiting the present invention, those skilled in the art can in the scope of the utility model
To make changes, modifications, substitutions and variations to the above described embodiments.
