Embodiment 1

[0048] A construction method for strengthening concrete structures using carbon fibers, comprising the following sequential steps:

[0049] (1) Concrete base treatment

[0050] Before the construction of carbon fiber reinforcement, part of the load should be removed as much as possible to minimize the load on the structure or components during carbon fiber pasting construction, and then if figure 1 As shown, the protective mortar 3 around the crack 1 is removed, and the surface of the concrete member 2 is smoothed with a grinder at the position where the carbon fiber sheet 5 is to be pasted, and the crack 1 with a width of less than 0.2 mm is coated and sealed with epoxy resin. , the crack 1 with a width between 0.2-1mm is filled with epoxy resin, and the crack 1 with a width greater than 1mm is treated with pressure potting. During the potting process, such as figure 2 As shown, a V-shaped groove 4 with a width of 20 mm and a depth of 10 mm should be chiseled at the crack 1...

Embodiment 2

[0072] Compared with the first embodiment above, the only difference is that the crack 1 is at the foot of the wall. In the step (4.3), before the undercoating step, as Figure 4 As shown, the hole 6 should be dug at the foot of the wall in advance. The depth of the hole 6 should make the carbon fiber cloth around the crack reach 400mm symmetrically, and the distance between two adjacent carbon fiber sheets along the direction of the crack should be 100mm.

Abstract

The invention relates to a construction method for reinforcing a concrete structure by using carbon fibers, belonging to the technical field of building constructions. The construction method comprises the following construction steps of: (1) carrying out a concrete foundation treatment; (2) coating priming paint; (3) carrying out incomplete part repair by utilizing epoxy putties; (4) sticking carbon fiber sheets; and (5) curing. The construction method disclosed by the invention has the advantages of simple and rapid construction, no need of any clamp, mould plate and support and low construction cost, and is suitable for each type of reinforced concrete structure or reinforcement and enhancement of the member, reinforced concrete structures, such as bridges, industrial and civil buildings and special structures, high-rise structures, impounding reservoirs, jars, culverts, tunnels, wharfs and harbors and the like, and is also suitable for the repair and enhancement of the structures.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a construction method for reinforcing concrete structures. Background technique [0002] Existing construction methods for strengthening concrete structures include traditional methods such as steel plate reinforcement and concrete reinforcement. During construction, complex procedures such as planting bars and anchors, assembling and disassembling fixtures, forming forms, supporting, pouring concrete, curing, and formwork removal are required. And auxiliary facilities, and take up a lot of space. Contents of the invention [0003] In order to solve the problems of complicated construction and large space occupation of existing construction methods for reinforcing concrete structures, the present invention provides a construction method for reinforcing concrete structures using carbon fibers, which includes the following sequential steps: [0004] (1) Concrete ba...
