Abstract
The utility model discloses a carbon fiber board anchorage device for use in civil engineering and building construction. The anchorage device is composed of two upper and lower plywoods used to clamp carbon fiber boards, a pressing board, a pressure bolt and an anchoring bolt. Veins for enhancing friction is arranged on the upper and lower plywoods surfaces meeting with the carbon fiber board. The middle part of the pressing board is protruding. The lower plywood is provided with a tapping hole matching with the pressure bolt, and the two upper and lower plywoods are clamped by the pressure bolt through the pressing board. The lower plywood is anchored on a concrete member to be reinforced through the anchoring bolt. The utility model can clamp and anchor the carbon fiber board uniformly, and the carbon thread of the carbon fiber board can not be broken even the carbon fiber board is expanded to a high prestressing condition.
Description
Technical field
The utility model relates to the carbon beaverboard anchorage that a kind of civil construction project is used.
Background technology
Carbon fiber sheet is a kind of than the high 7-10 of common iron intensity novel high-strength material doubly, sticks on 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 tangible advantage of common stickup carbon fiber reinforcement.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; Therefore how 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, with the even stressed clamping of carbon fiber sheet and guarantee that it is present problem demanding prompt solution that carbon filament is not cut off.
The utility model content
The purpose of this utility model is to provide a kind of can press from both sides the anchor carbon fiber sheet equably, and guarantees its stretch-draw can not cut off the carbon beaverboard anchorage that the civil construction project of carbon filament is used to high-strength prestressed state.
The utility model ground tackle comprises two clamping plate, pressing plate, hold-down bolt and the anchor bolt up and down that is used to press from both sides carbon fiber board, up and down two clamping plate with the contact surface of carbon fiber board on be provided with the lines that is used to increase friction, the interlude of pressing plate is set as convex, lower plate is provided with the screw that matches with hold-down bolt, make two clamping plate clamping up and down by hold-down bolt by pressing plate, lower plate anchors on the concrete member to be reinforced by anchor bolt.
The utility model is owing to the interlude at pressing plate is provided with projection, when the hold-down bolt of pressing plate periphery compresses, pressing plate acts on train wheel bridge with its interlude, thereby two clamping plate do not produce excessive flexural deformation and carbon fiber board are bestowed uniform clamping force about making, in the time of guaranteeing that carbon fiber board is stretched thus, form uniform prestressing force.Because two clamping plate are used to increase the lines of friction contact surface being provided with carbon fiber board, when two clamping plate clamp the carbon fiber board application of force by pressing plate, utilize the hardness of carbon fiber board to be lower than the characteristics of two clamping plate (steel), the surface of carbon fiber board will form with two clamping plate on the corresponding lines that is meshed of described lines, make thus two clamping plate and carbon fiber board tightly snap-in together, further guaranteed carbon fiber board in loading process suffered stress equilibrium and in stretch-draw (carbon filament can not cut off under＞1600Mpa) the state to high-strength prestressed.Therefore carbon fiber board can be anchored on the concrete member by the utility model ground tackle after being subjected to prestressing force, and is pasted together by adhesive glue and concrete member, conversely member is imposed precharge pressure, plays the reinforcement effect to the concrete member well.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the sectional view of Fig. 1 along the A-A line.
Fig. 3 is that the B of Fig. 1 is to view.
The specific embodiment
The utlity model has lower plate 1, train wheel bridge 2, pressing plate 3, hold-down bolt 4, anchor bolt 5 as can be seen from Figure 1, the interlude of pressing plate is designed to convex, lower plate 1 is provided with the screw 6 that cooperates with hold-down bolt 4, carbon fiber board I is clipped between lower plate 1 and the train wheel bridge 2, pass pressing plate 3 and train wheel bridge 2 screw-in screws 6 by hold-down bolt 4, make the convex surfaces 9 of pressing plate 3 act on train wheel bridge 2, two clamping plate clamp carbon fiber board up and down.Lower plate 1 and train wheel bridge 2 are useful on lines 8 (see figure 2)s that increase frictional force with the contact surface 7 of carbon fiber board, so that go up lower plate and carbon fiber board strong bonded.Pressing plate 3 adopts more than 2 better, and this example has adopted 5, and this 5 block pressur plate respectively is pressed on the train wheel bridge 2 side by side by a pair of hold-down bolt, compares with adopting the monolithic pressing plate, and the polylith pressing plate more helps compressing two clamping plate (see figure 3)s.Anchor bolt 5 is anchored in lower plate 2 on the concrete spare to be reinforced.
