[0003] Publication number is that the patent application technology of CN 104631851 A discloses " a kind of prestressed carbon fiber plate stretching device and its method for stretching prestressed carbon fiber plate ", and this device is used for the reinforcement of carbon fiber plate and has the following deficiencies: 1. Due to the characteristics of the carbon fiber plate material itself, there is a large gap between the reinforced carbon fiber plate and the reinforced component, and the applied prestress is only transmitted to the component by the anchor bolts at both ends, and the integrity is poor; 2. The device has no effect on the carbon fiber plate The tensioning device is relatively cumbersome, and the tension end screw is long, and it protrudes from the surface of the structure after reinforcement, which affects the appearance of the reinforced structure

Embodiment 1
[0044] like Figure 1~17 As shown, in this embodiment, the reinforced concrete box girder 9 is used as the reinforcement object, and it is reinforced with double-layer prestressed carbon fiber cloth. The width of the carbon fiber cloth is 150 mm, as follows:
[0045] A prestressed fiber cloth reinforced beam tension anchoring device, including two fixed supports 1, a fixed end anchor 2A, a tension end anchor 2B, two clips 3, two anchor short screws 6A, two An anchoring long screw 6B, four chemical bolts 7, fiber cloth 8, prestressing frame 4 and jack 5.
[0046] The fixed support 1 is in the shape of a cuboid. There are two circular through-holes 11 for installing chemical bolts 7 on it, and a circular anchor hole I12 for connecting with tension-end anchor 2B or fixed-end anchor 2A on each side.
[0047] The fixed end anchor 2A is in the shape of a cuboid. There is a circular anchor hole II2A1 for connecting with the fixed support 1 at both ends, and there is a 2mm wide recta...

Abstract
The invention discloses a tensioning and anchoring device for prestressed fiber cloth reinforced beams and a construction method of the device. The device comprises fixed supports, a fixed end anchorage device, a tensioning end anchorage device, clamping pieces, short anchoring screws, long anchoring screws, chemical bolts, fiber cloth, a prestress application frame and a jack, wherein the fixed supports, the fixed end anchorage device and the tensioning end anchorage device are cuboid; the fixed supports are fixed with a to-be-reinforced beam through the chemical bolts; the fixed end anchorage device and the tensioning end anchorage device are connected with the fixed supports through the short anchoring screws and the long anchoring screws respectively; a rectangular through seam allowing the fiber cloth to pass is formed in the fixed end anchorage device; wedge-shaped holes allowing insertion of the clamping pieces are formed in the tensioning end anchorage device, and the clampingpieces are wedged into the wedge-shaped holes, so that clamping of the fiber cloth is realized. The construction method comprises steps as follows: firstly, the anchorage devices are mounted, then thefixed supports are assembled and the anchorage devices are fixed, finally, the prestress application frame and the jack are mounted, and tensioning and anchoring are implemented. The device is reasonable and simple in structure and convenient to operate and can be reused, and the applied prestress is large.
Description
technical field [0001] The invention relates to a prestressed fiber cloth tension anchoring device and its construction method, in particular to a prestressed fiber cloth reinforced beam tension anchorage device and its construction method, which can be used to strengthen concrete structures and belong to the construction and bridge engineering reinforcement field. Background technique [0002] Fiber composite reinforced materials have the characteristics of high unidirectional tensile strength, light weight, high elastic modulus, small volume, and corrosion resistance. After reinforcement, the cross-section and load of the original structural members do not increase significantly, so they are widely used in concrete structures. Reinforcing. In the prior art, there are few tension anchoring devices for prestressed fiber cloth reinforced steel bars and prestressed concrete, and the applied prestress is relatively small. [0003] Publication number is that the patent applica...
