Description
Technical field:
The utility model relates to a kind of ground tackle, the carbon beaverboard anchorage of using in particularly a kind of civil construction project.
Background technology:
Carbon fiber sheet is the novel high-strength material, is attached to the intensity that the concrete component surface is used for stiffener in civil construction project usually.If will be anchored in component surface behind its pre-pretensioning before pasting, flexural strength, crack resistance that can stiffener can also make full use of its intensity.Therefore pre-stressed carbon fiber reinforced Concrete member has than the fiber reinforced tangible advantage of common stickup.But stretch-draw of prestressed reinforcement Technology Need and anchoring carbon fiber sheet, though and carbon fiber sheet hot strength height lateral shear intensity is low, its folder is cut off carbon filament during anchor easily, do not clamp and can skid; Sheet material has certain width in addition, and it also is a very very difficult thing that the ground tackle clamping plate will evenly clamp carbon fiber board at whole width range, therefore how carbon fiber sheet is clamped evenly and guarantee that it is present problem demanding prompt solution that carbon filament is not cut off.
Usually carbon fibre material is applied prestressing force, all adopt the method for epoxy composite material, think that direct employing mechanical type clamping meeting causes very big damage to carbon filament, can't meet the requirements of chucking power usually the carbon fiber board bond-anchorage.But carbon fiber board bond-anchorage member is bigger, be not suitable for engineering and use, and bonding uses the epoxy compound cost than higher.Application number is in the disclosed technical scheme of 200610031436.2 " carbon beaverboard anchorage that civil construction project is used " patents of invention, adopting the polylith pressing plate to compress lower plate makes lower plate clamp the clamping carbon fiber board by hold-down bolt by pressing plate, because pressing plate is many, be difficult to guarantee the even of every block pressur plate thrust; Might skidding tightly not occur because of folder if control the clamping force of bad bolt when installing, secondly, need enough experiences during construction and carry out fitting operation,, need control corresponding clamping force well the carbon fiber sheet of different size.
The utility model content:
The technical problems to be solved in the utility model is: a kind of carbon fiber board uniform-compression in clamping process that makes is provided, anchoring property is reliable, the carbon beaverboard anchorage of while compact conformation, making easy construction, to solve reliably anchoring of carbon fiber board, the problem that carbon filament is easily cut off overcomes above-mentioned with the method for carbon fiber board bond-anchorage and the weak point of existing " carbon beaverboard anchorage " simultaneously.
The technical scheme that solves the problems of the technologies described above is: a kind of carbon beaverboard anchorage, form by anchor slab and intermediate plate, anchor slab is an integral body, in a wedge shape through hole is arranged, intermediate plate be two-piece type wedge, its wedging anchor slab clamp behind carbon fiber board with anchor slab in wedge shape through hole tight fit.
Described anchor slab is that cross section is the square oval or circular cylinder of rectangle, has cross section in it and be square oval or circular, the wedge shape through hole that the longitudinal section has tapering of rectangle.
Further technical characterictic of the present utility model is: contact the reinforcing material of fiberboard contact more fully what the contacted clamping face of intermediate plate and carbon fiber board had that one deck makes intermediate plate and fiberboard, at the clamping face of intermediate plate or be pasted with sand paper or be stained with diamond dust or be coated with colloid or rubber, plastic materials are arranged.
Further again technical characterictic of the present utility model is: the contact surface at intermediate plate and anchor slab is coated with lubrication oil or lubricating grease.
Because adopt said structure, the carbon beaverboard anchorage of the utility model has following beneficial effect:
1, the anchoring property of this ground tackle is reliable, the carbon beaverboard anchorage of the utility model is made up of anchor slab and intermediate plate, anchor slab is an integral body, in be designed to the wedge shape through hole, intermediate plate is the two-piece type wedge, behind the intermediate plate wedging anchor slab, stressed by lozenges evenly is delivered to the chucking power of intermediate plate on the carbon fiber board of clamping.When carbon fiber board was subjected to axial force, by the wedge effect, intermediate plate was with its reliable grip, and intermediate plate, anchor slab, carbon fiber board form an anchoring unit like this, and anchoring property is reliable; Secondly, the utility model is at the clamping face of intermediate plate or paste sand paper, diamond dust or smear colloid or be coated with one deck rubber, plastic materials and so on fiberboard contact reinforcing material to avoid the pinch off carbon filament, make intermediate plate more abundant with contacting of carbon fiber board, can increase frictional force again, thereby make carbon fiber board in stretching process, evenly bear lateral stress, guarantee effectively clamping carbon fiber board of ground tackle, further improved the anchoring property of ground tackle.
2, simple in structure, compact, easy to make.The carbon beaverboard anchorage of the utility model is made up of anchor slab and intermediate plate, and is simple in structure, compact, easy to make, but but both can field fabrication also factory process, the make efficiency height.
3, the utility model carbon beaverboard anchorage shape is varied, as anchor slab can be that cross section is the square oval or circular cylinder of rectangle, have cross section in it and be square oval or circular, the wedge shape through hole that the longitudinal section has tapering of rectangle, cross section is square oval or circular, the wedge shape through hole tight fit that the longitudinal section has tapering of rectangle in profile that intermediate plate closes up and the anchor slab, can satisfy the different requirements of different construction environments.
4, constructing operation is convenient, the efficient height.
