Abstract

The utility model discloses a prestress carbon fiber cloth stretching pedestal. A group of lifting cylinder (1) is arranged below a bridge-type beam (2). An anchoring member (3) with a roll shaft (5) is arranged above one end of the bridge-type beam (2). A stretching member (4) with a roll shaft (6) is arranged above the other end of the bridge-type beam (2) through a group of connecting members (7). At least two beams (10) are connected with the lower part of the bridge-type beam (2) positioned on the same side with the stretching member (4). A stressing plate (11) is connected with the lower parts of two beams (10). The bases of a group of stretching cylinders (9) are arranged on the bottom face of a frame-type stretching clamp (8). The stretching clamp (8) is hung on one end of a carbon fiber cloth. The utility model exerts prestress on the carbon fiber filament of the carbon fiber cloth evenly and precisely; therefore, the prestress carbon fiber cloth has less stress loss in loading phase. The construction and operation are simple and safe.

Description

Prestressed carbon fibre cloth stretching bed seat

Technical field

The utility model relates to building operations aids such as bridge, is specifically related to prestressed carbon fibre cloth stretching bed seat.

Background technology

At present, common carbon fibers cloth is applied to consolidation of concrete structure, the reinforcement technology is very ripe, but when common carbon fibers cloth is applied to consolidation of concrete structure, reinforcement, it is passive stressed that carbon cloth belongs to, the mechanical property of the high-strength tension of carbon cloth is not fully exerted, thereby has caused the waste of material.

Summary of the invention

The purpose of this utility model is: provide a kind of prestressed carbon cloth to rise and draw pedestal, utilize this pedestal can apply the prestressing force of certain numerical value to carbon cloth, the mechanical property of the high-strength tension of performance carbon cloth, prestressed carbon cloth is sticked on concrete beam basal surface to be reinforced, and pasting success rate can reach more than 90%.

Technical solution of the present utility model is: this pedestal is by hoist cylinder, bridge type beam, anchoring piece, the stretch-draw part, roll shaft, connector, tension clamp, the stretch-draw oil cylinder, crossbeam, stressed plate is formed, one group of hoist cylinder is installed below bridge type beam, the anchoring piece of mounting strap roll shaft above an end of bridge type beam, above the other end of bridge type beam, pass through the stretch-draw part of one group of connector mounting strap roll shaft, below the bridge type beam that is positioned at stretch-draw part homonymy, connect at least two crossbeams, the below of two crossbeams connects stressed plate, the base of one group of stretch-draw oil cylinder is placed on the bottom face of frame type tension clamp, and the tension clamp suspension type is fixed on an end of carbon cloth.

In the prestressed carbon fibre cloth stretching bed seat of the present utility model, bridge type beam can segmentation connect the adjustable length of bridge type beam.

In the prestressed carbon fibre cloth stretching bed seat of the present utility model, between bridge type beam and carbon cloth, establish one group of auxiliary support frame.

In the prestressed carbon fibre cloth stretching bed seat of the present utility model, setting pressure table on the stretch-draw oil cylinder.

During construction, by the technical scheme installed base, carbon cloth one end of cutting processing is fixed on the fixed axis of bridge type beam of anchoring piece side, carbon cloth draws to the roll shaft of stretch-draw part by the roll shaft top of anchoring piece, the other end of carbon cloth is fixed by the fixed axis on the frame type tension clamp, tension clamp is placed in and is positioned at the roll shaft below between two crossbeams, the base of stretch-draw oil cylinder is placed on the bottom face of frame type tension clamp, open the stretch-draw oil cylinder, the stressed plate that the plug cock of stretch-draw oil cylinder is aimed at two crossbeams upwards applies reverse prestressing force to carbon cloth, when reaching the design prestress value, screw the mechanical lock of stretch-draw oil cylinder, and one group of auxiliary support frame is placed in tensioning carbon cloth between carbon cloth and the bridge type beam, apply bonding agent on the carbon cloth, open one group of hoist cylinder jacking pedestal, carbon cloth is sticked on the concrete beam basal surface to be reinforced.

The utlity model has following advantage: 1. the carbon fiber wire of carbon cloth is stressed evenly; 2. prestressing force numerical value applies accurately; 3. prestressed carbon cloth is in that to hold lotus stage stress loss little; 4. constructing operation is simple and safe.
