Description
Technical field the utility model relates to a kind of carbon fiber cloth prestressed tensioner that is used for the reinforced concrete structure stabilization works.
Background technology is a kind of effectively structural strengthening method in the whole bending resistance that structural member tensile region affixing carbon fabric improves concrete or steel work.Because carbon fiber cloth in light weight and its tensile strength is very high based on being gradually improved of carbon fiber cloth technology for applying, being pasted carbon fiber cloth structural strengthening technology and obtained using more and more widely.Paste carbon fiber cloth at present in the engineering and generally all adopt directly stickup, carbon fiber cloth is the nature relaxed state after pasting basically, and this method is called the nature mounting method.Because the modulus of elasticity of carbon fiber cloth and original structure is different, the carbon fiber cloth that natural mounting method is pasted reaches best stress simultaneously with original structure is very difficult, and might working as carbon fiber cloth, stressed afterwards original structure is destroyed.The effective way that overcomes the above problems applies prestressing force to carbon fiber cloth exactly, is about to paste body structure surface again after carbon fiber cloth stretches.Therefore be necessary to provide a kind of tensioning equipment that can finish above function, this device must possess following function: 1, and can provide enough pulling force that carbon fiber cloth is stretched to predetermined state; 2, the pulling force that applies should be able to reading and control that can be artificial; 3, installation and easy to operate can accommodate the on-the-spot application on a large scale of engineering construction.
Also do not have in the present actual engineering can be practical carbon fiber cloth prestressed stretch-draw product, there are following shortcoming in existing roll type stretch-draw and hydraulic jack formula method for stretching: tensioning equipment is too complicated, tension force keeps need taking measures specially, use and inconvenience and pulling force metering are installed need by supplementary means etc.
The summary of the invention the purpose of this utility model is at above-mentioned present situation, aims to provide a kind of easy to install, the spiral carbon fiber cloth prestressed tensioner that can control pulling force.
The implementation of the utility model purpose is, spiral carbon fiber cloth prestressed tensioner, fixed axis 8, compression axis 11 are fixed by fixed axis bearing 1, compression axis bearing 2, there is carbon fiber cloth installation shaft 9 compression axis 11 tops, carbon fiber cloth installation shaft 9 two ends are positioned on the carbon fiber cloth shifting axle bearing 14, be equipped with the carbon fiber cloth shifting axle 3 of band carbon fiber cloth card article 12 in the middle of the carbon fiber cloth shifting axle bearing, there is stretching screw rod 4 at carbon fiber cloth shifting axle 3 centers, stretching screw rod 4 is equipped with hold-down nut 7 by hold-down nut established angle bearing 5 and hold-down nut 7 location on the angle bearing 5.
When using the utility model, at first carbon fiber cloth two ends to be tensioned are inserted respectively in the mounting groove of fixed axis 8 and carbon fiber cloth installation shaft 9, and, fixed axis 8 is inserted in the fixed axis bearing 1, and be fixed on the installation metope respectively with in carbon fiber cloth card article 12 card entry slots; Length by carbon fiber cloth to be tensioned is installed in hold-down nut established angle bearing 5 on the metope, carbon fiber cloth installation shaft 9 is inserted in the carbon fiber cloth shifting axle bearing 14, dress stretching screw rod 4, carbon fiber cloth compression axis bearing 2 is installed, make carbon fiber cloth be close to metope near carbon fiber cloth shifting axle bearing end, rotate up stretching screw rod 4 with the reading torque spanner, stop reinforcing after carbon fiber cloth tensioning stretch-draw is put in place.After the carbon fiber cloth after the stretch-draw and metope bonding is fixing, withdraw from the utility model.
The utility model screw rod tensile force can be artificial control, easy to install and use, but self-locking after the screw rod stretch-draw, stretching force can keep naturally.The utility model can be used for the carbon fiber cloth of plate, beam and plane column and pastes preceding pre-stretch-draw.
Description of drawings
Fig. 1 is the utility model stretch-draw pre-structure schematic diagram
Fig. 2 is a structural representation after the utility model stretch-draw
Specific embodiment the utility model is by fixed axis 8, compression axis 11, carbon fiber cloth installation shaft 9, carbon fiber cloth shifting axle 3 and bearing 14 thereof, compositions such as stretching screw rod 4, hold-down nut established angle bearing 5.
With reference to Fig. 1,2, along fixed axis 8 and fixed end carbon fiber cloth installation shaft 9 vertically have a wide elongated slot of 2mm, fixed axis 8 is placed restrictions on mutually circumferentially rotation with fixed axis bearing 1 by six sides.2 of compression axis 11 and compression axis bearings can rotate mutually.There is bowl-type thrust metal 13 stretching screw rod 4 and carbon fiber cloth installation shaft 9 junctions.Fixed end carbon fiber cloth installation shaft 9 two ends have installation shaft spline clamp 10.
With reference to Fig. 1,2, the utility model course of work is as follows: at first carbon fiber cloth two ends to be tensioned are inserted respectively in the mounting groove of fixed axis 8 and carbon fiber cloth installation shaft 9, and respectively with in carbon fiber cloth card article 12 card entry slots, the fixed axis 8 that will be inserted with carbon fiber cloth and card article then and carbon fiber cloth installation shaft 9 are to each two week of spinning of different directions; Fixed axis 8 is inserted in the fixed axis bearing 1, fixed axis bearing 1 is fixed on installs on the metope again; Length by carbon fiber cloth to be tensioned is installed in the suitable position of installation metope with hold-down nut established angle bearing 5; The carbon fiber cloth installation shaft 9 that carbon fiber cloth and card article will be housed is again inserted in the installing hole of carbon fiber cloth shifting axle bearings 14, and with installation shaft spline clamp 10 with carbon fiber cloth installation shaft 9 axial restraints, it can not be rotated; The splayed load end of stretching screw rod 4 is inserted in the bowl-type thrust metal 13, and the hexagonal prism head end revolved from hold-down nut 16, and it is just passable that the preceding hexagonal prism head of stretch-draw has just passed hold-down nut established angle bearing 5.Carbon fiber cloth compression axis bearing 2 is installed, is made carbon fiber cloth also be close to metope near the mobile support saddle end, its state as shown in Figure 1.Rotate up stretching screw rod 4 with the reading torque spanner, the stretching screw rod will be with carbon fiber cloth shifting axle bearing 14 to move to the carbon fiber cloth tension direction, thereby make the carbon fiber cloth tensioning.The reading of torque spanner has corresponding relation with tensile force, so can stop reinforcing after reading reaches predetermined value, prestressed stretch-draw finishes.Because the self-locking effect of stretching screw rod, screw rod can not become flexible after torque spanner comes loose, and the stretching force of carbon fiber cloth can remain unchanged always.After the carbon fiber cloth after the stretch-draw and metope bonding was fixing, the utility model can be removed from metope, and the utility model is reusable.
