Problems solved by technology

[0003] The above prestressed carbon fiber plate tensioning device only stretches one carbon fiber plate. If the concrete structure to be reinforced has a large area, then multiple carbon fiber plate tensioning devices need to be installed side by side. The disadvantage of this is that the force is scattered, and each The anchors act on the respective connected concrete, unable to form a stable single tension force

Embodiment 1

[0017] like figure 1 As shown, the multiple prestressed carbon fiber plate reinforcement devices include an anchor plate 1 and several prestressed carbon fiber plate reinforcement systems. The two ends of the prestressed carbon fiber plate reinforcement system are sheet-type anchors 2. Located at both ends of the prestressed carbon fiber plate reinforcement system, four anchors 2 can be fixed on the anchor plate 1, and there are several large anchor holes 4 on the anchor plate 1 for anchor bolts to pass through. A small anchor hole 5 for fixing the sheet-type anchor 2 on the anchor plate 1 is opened, and the upper surface of the anchor plate 1 is marked with an alignment indicator frame 3 of the carbon fiber plate.

[0018] The four sheet-type anchors 2 are arranged side by side at equal distances, and the large anchor holes 4 are arranged on both sides of the sheet-type anchors 2, and there are three large anchor holes 4 on each side.

Embodiment 2

[0020] like figure 2 As shown, six sheet-type anchors 2 can be fixed on the anchor plate 1, and the sheet-type anchors 2 are arranged in two rows, front and rear, with 3 sheet-type anchors 2 in each row, and the front and rear rows are arranged alternately.

[0021] The large anchor holes 4 are distributed on the anchor plate 1 in a matrix, four in the horizontal direction and eight in the vertical direction.

Abstract

The invention provides a reinforcing device for multiple prestressed carbon fiber plates. The reinforcing device comprises anchoring plates and reinforcing systems of the multiple prestressed carbon fiber plates; the two ends of the reinforcing systems of the multiple prestressed carbon fiber plates are pressing-piece-type anchorage devices, and the two anchoring plates are correspondingly locatedat both ends of the reinforcing systems of the multiple prestressed carbon fiber plates; three to eight pressing-piece-type anchorage devices can be fixed to the anchoring plates, a plurality of large anchoring holes for penetrating through of anchoring bolts are formed in the anchoring plates, and small anchoring holes for fixing the pressing-piece-type anchorage devices to the anchoring platesare further formed in the anchoring plates; and alignment indicating frames of the carbon fiber plates are marked on the upper surfaces of the anchoring plates. The reinforcing systems of the multipleprestressed carbon fiber plates can be simultaneously acted on one anchoring plate, and then tensioning force is applied on a concrete structure through the anchoring plates, so that the applied force is more stable and single.

Description

technical field [0001] The invention belongs to the technical field of prestressed carbon fiber boards, and relates to a reinforcement device for multiple prestressed carbon fiber boards. Background technique [0002] Such as Chinese patent application number 201410826947.8 published prestressed carbon fiber plate tensioning device and its method for tensioning prestressed carbon fiber plate, the device includes carbon fiber plate anchorage, tension jack and by the pressure plate, fixed end support, A prestressed carbon fiber plate auxiliary tensioning device composed of a tension baffle, a tension rod and a tension end support. The fixed end support and the tension end support are both cuboids, and there are four on them for installing chemical anchors. There is a circular through hole on both sides of the tension end support for installing the tension rod; the pressure plate and the tension baffle are in the shape of a cuboid, and there are two round holes for installing s...
