Abstract

The utility model is a kind of anti-bend reinforced device of carbon cloth for reinforced beam, belongs to the technical field of building structure strengthening, for the anti-bend reinforced of reinforced beam.The device includes:Carbon cloth, connector, dissipative cell, anchoring piece, anchor bolt and bolt;Anchoring piece anchors to reinforced beam on Column border node by anchor bolt, and dissipative cell is connected with anchoring piece and dissipative cell respectively by bolt, carbon cloth and connector bonding connection.Compared with traditional outer patch carbon cloth method, which obtains good ductile performance, and simple structure while improving the anti-bending bearing capacity of reinforced beam, easy for construction.

Description

A kind of anti-bend reinforced device of carbon cloth for reinforced beam
Technical field
The utility model belongs to the technical field of building structure strengthening, more particularly to a kind of carbon for reinforced beam The anti-bend reinforced device of fiber cloth.
Background technology
Reinforced beam is widely used in as basic flexural member in various building structure.As time goes by, Early stage reinforced beam has been enter into the work with cracking stage, ignores anti-since Earlier designs more consider gravity laod effect Shake ability, so shockproof effect is poor.As once usage time extension or macroseism occur, reinforced beam will occur Serious damage, considers for safety and lives and properties, carries out anti-bend reinforced being necessary to reinforced beam.
Carbon cloth due to it is high-strength efficiently, that durability is good, acid and alkali-resistance salt corrosion is strong, heat-resisting and cold resistance is good etc. is excellent Point becomes and solves the prior art good selection of problems.Therefore, outer patch carbon cloth method is usually used in the anti-of armored concrete Curved reinforcing, when construction, paste carbon cloth in the bottom of reinforced beam with binder, are anchored at the both ends of beam.This Kind method can design the span centre anti-bending bearing capacity for improving reinforced beam, but since carbon cloth belongs to fragile material, pass The reinforced beam damage -form that the outer patch carbon cloth method of system is reinforced shows as brittle break, without significantly broken before destroying Bad sign, energy dissipation capacity are insufficient, and ductility is poor, and workload is larger when construction, and cohesive reliability is also not readily available guarantee.
Invention content
The problems of when in order to solve traditional outer patch carbon cloth method to flexural strengthening of RC beams, this reality A kind of anti-bend reinforced device of the carbon cloth for reinforced beam, device simple structure, the construction party are proposed with novel Just, the good ductility obtained while realizing the span centre anti-bending bearing capacity for improving reinforced beam, energy consumption is abundant, breaks There is manifest signs before bad, improve the anti-seismic performance of reinforced beam.
The technical solution adopted in the utility model is:A kind of anti-bend reinforced dress of carbon cloth for reinforced beam It sets, including:Carbon cloth, connector, dissipative cell, anchoring piece, anchor bolt and bolt;Connector has rectangular section and triangle Section, there is rectangular section bolt hole to be constructed for hollow thin wall for connecting dissipative cell, triangular sections, for bonding two panels carbon up and down Fiber cloth;Dissipative cell is two strip mild steel, and both ends have bolt hole to be respectively used to connection anchoring element and connector, in Between section be provided with energy consumption hole for deformed in tension energy consumption;Anchoring piece is the angle steel for welding two ribbed stiffeners, respectively has one on ribbed stiffener A bolt hole, for connecting two dissipative cells, another tool is used as the connection with reinforced concrete beam column node there are four anchor hole.
Preferably, the carbon cloth is bonded together for two panels, has identical width with the reinforced beam reinforced Degree.
The anti-bend reinforced device of a kind of carbon cloth for reinforced beam that the utility model is invented, using carbon fiber Wei Bu is as strength enhancing component, the characteristic for making full use of its tensile strength high, and two strip mild steel of simultaneous selection are as consumption Energy element, improves the deformability of institute's reinforcement of rc beam, is obtained compared to traditional outer patch carbon cloth method ductility good It is good to be promoted;And the device eliminates the extensive works such as chipping concrete surface, affixing carbon fabric so that work progress is more It is convenient.
