Split, cause reinforcement corrosion, have influence on floor security and normal usage.Or because of the change of building function, the increasing of load
Plus, there is deficiency in the bearing capacity of floor.The factors such as packless, the flooring surface layer destruction in gap between precast floor slab plate stitch, usually
There is drainage, have a strong impact on the use of building.
In building structure, cast-in-situ floor, especially multilayer and skyscraper are come frequently with commerical ready-mixed concrete.But applied in structure
In work, occur various problems unavoidably：1. using inferior materials and turning out substandard goods for construction party causes reinforcement amount not enough；2nd, profit pump mortar does not clear up dry
Only, cause mortar to be mixed into plate, cause bearing capacity of floor slab not enough；3rd, building causes load on plate to increase using the change of function,
Situations such as bearing capacity of floor slab occurs not enough.
Conventional floor reinforcement technique has plate bottom dead burning plate to reinforce, the method such as outer viscous fibre sheet material.Above-mentioned reinforcement means is deposited
Not high in reinforcement material rate of utilization of strength, durability is poor, the problems such as reinforcement cost is higher.

For defect present in prior art, the purpose of this utility model is to provide a kind of reinforcing device for slab, from
Economy and construction mobility are set out, and bending resistance reinforcing are carried out to floor construction, to ensure security performance and use
Performance is met.
In order to solve the above-mentioned technical problem, the utility model, which is adopted the following technical scheme that, is achieved：
A kind of reinforcing device for slab, including it is fixed on the reinforced mesh of soffit, in addition to L-type lacing wire, described L-type
In one end implantation soffit of lacing wire, the other end of L-type lacing wire is connected at the node of reinforced mesh；
Open up fluted in floor soleplate face, high ductility concrete formation shear key, described groove are filled in a groove
A diameter of 20~40mm, the depth of groove is 20~30mm, and the spacing of described adjacent grooves is 300~1000mm；
High ductility concrete topping, described high ductility concrete are coated with described soffit and all reinforcing bars
The thickness of surface layer (5) is 20~50mm.
The utility model also has following distinguishing feature：
The spacing of described adjacent L-type lacing wire is that the length in 600~1200mm, L-type lacing wire implantation soffit (1) is
50~80mm, a diameter of 6mm of L-type lacing wire.
Bar diameter in described reinforced mesh is 6~12mm, and bar spacing is 200~600mm.
Compared with prior art, the beneficial effects of the utility model are：
(1) bracing means of the present utility model reinforces floor using high ductility concrete topping, higher anti-using having
Tensile strength, multiple cracking carry out the high ductility concrete of characteristic and high-durability to improve the anti-bending bearing capacity and entirety of floor
Property, strengthen the water resistance of floor, improve structure durability；Using the higher toughness of high ductility concrete, directly make circular
Shear key, that is, improve surface layer and the cooperative ability of former floor, saves and makes reinforcing bar shear key process, and shear key
Material is consistent with surface material, can construct simultaneously, simplifies working procedure and shortens the duration.
(2) precast floor slab that the utility model is reinforced has good globality, improves the anti-seismic performance of building, this
The floor that device is reinforced has good durability, can extending structure service life, improve the bearing capacity of existing floor.
