Embodiment

[0014] Example: such as figure 1 , figure 2 , image 3 As shown, 1. A prestressed carbon fiber plate detachable anchor, comprising a detachable anchor 1, a slide 2, a tension support 3, an anchor plate 4 and a carbon fiber plate 5, is characterized in that: the slide The track 2 is installed at the bottom, and the detachable anchor 1 is installed on the upper part of the slideway 2; the other part is the tension support 3, the anchor plate 4, and the carbon fiber plate from top to bottom. 5. The detachable anchor 1 is divided into five parts: top 6, gland 7, wedge 8, base 9, and write-off 10. One end of the top 6 is connected to the side of the gland 7, and the other end is connected to the The side of the tension support 3; the wedge 8 is installed on the base 9. The detachable anchor 1 is wedge-shaped, and the wedge 8 has the same inclination angle as the wedge groove, and the angle is 2 0 -5 0 . The wedge 8 is made of 40Cr, and the others are made of stainless steel,...

Abstract

The invention discloses a detachable anchorage device with a prestressed carbon fiber plate. The detachable anchorage device comprises detachable anchorage device bodies, slide rails, tension supports, anchor plates and a carbon fiber plate. The slide rails are mounted at the bottom of the detachable anchorage device, and the detachable anchorage device bodies are mounted on the upper portions of the slide rails; another portion of the detachable anchorage device is sequentially provided with the tension supports, the anchor plates and the carbon fiber plate from top to bottom; each detachable anchorage device body comprises an ejector head, a gland, a wedge, a base and a pin, one end of each ejector head is connected with a side surface of the corresponding gland, and the other end of each ejector head is connected to a side surface of the corresponding tension support; the wedges are mounted on the bases. The carbon fiber plate is adhered with a concrete base plane by epoxy adhesive, and the epoxy adhesive is made of soft metal materials with the thicknesses ranging from 1 mm to 3 mm. Inclination angles of the detachable anchorage device which is a wedge-shaped anchorage device range from 2 degrees to 5 degrees. Compared with fixed anchorage devices, the detachable anchorage device has the advantages that the detachable anchorage device is low in cost and high in universality; soft metal plates for adhering the carbon fiber plate can be aluminum plates, copper plates and aluminum alloy plates, and accordingly stress can be relieved in prestress applying procedures.

Description

technical field [0001] The invention relates to an anchor, in particular to a detachable anchor for a prestressed carbon fiber plate. Background technique [0002] Prestressed carbon fiber panels are widely used in the reinforcement and upgrading of building concrete. The anchor is the core of the prestressed carbon plate, which can effectively transfer the load on the carbon fiber plate to the reinforced building. Existing anchors are mainly divided into two categories, namely: permanent anchors and detachable anchors. Permanent anchor After the building is reinforced, the anchor will be permanently connected to the carbon fiber plate. Although it has strong stability, this kind of anchor is difficult to popularize because of its processing and material problems and high cost. After the detachable anchor is reinforced, the anchor can be disassembled and recycled, and the overall cost is greatly reduced. At the same time, the safety and stability are not reduced compared w...
