Description

A kind of reinforcing device for slab
Technical field
The utility model is related to building structure aseismatic and reinforcement technique field, is specially that one kind is used for Concrete Structures of Tall Building Floor anti-seismic strengthening device.
Background technology
Floor is a kind of structural elements for being widely used in building.Floor in the structure, is mainly used in bearing vertical load. Common floor form is prefabricated hollow floor and cast-in-place concrete floor.
Prefabricated hollow floor is common in old building.Process is being used, prefabricated board bottom is usually because plate base concrete is opened 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.
The content of the invention
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.
