Embodiment 1

[0021] A carbon fiber grid reinforcement method. The specific steps of the carbon fiber grid reinforcement method are as follows:

[0022] S1: Prepare wet construction machinery: prepare wet construction machinery for standby as required, and check whether the machinery can work normally;

[0023] S2: Treatment of the original concrete base course: the original concrete base course of the building is treated, the debris of the concrete base course is removed, the sanding machine is used for deep sanding or hydraulic sanding, and the base course is pre-soaked;

[0024] S3: Mixing of CWSM wet-jet polymer mortar: Use the wet construction machinery prepared in step S1 to fully stir the CWSM wet-jet polymer mortar, stir it evenly, and use it for later use. The density of the mortar is controlled to 2.05kg / dm 3 ;

[0025] S4: The first layer of mortar spraying: spray the homogeneously stirred CWSM wet spray polymer mortar in step S3 through a high-pressure spray gun on the base layer that ha...

Abstract

The invention discloses a carbon fiber grid reinforcing method. The carbon fiber grid reinforcing method comprises the following specific steps of S1, wet-method construction machinery preparing, S2, original concrete basic layer processing, S3, mixing of CWSM wet-method spray polymer mortar, S4, spraying of a first layer of the mortar, S5, CFN carbon fiber grid cutting, S6, CFN carbon fiber grid laying, S7, temporary fixing of the tail part of a CFN carbon fiber grid, S8, laying of the CFN carbon fiber grid in the motor layer, S9, spraying of a second layer of the mortar, and S10, finishing. The carbon fiber grid reinforcing method is simple in process and has the following characteristics that construction is easy, rapid and convenient, specifically, the basic layer does not need flatting and repairing work before construction, so that the construction speed is high; the anti-crack effect is good, specifically, the method is suitable for structural crack controlling and reinforcing; and durability is good, specifically, carbon fibers are inert materials, so that corrosion is avoided, and the alkaline protection effect is taken on original steel bars, so that the carbon fiber grid reinforcing method is more convenient to popularize.

Description

Technical field [0001] The invention relates to the technical field of reinforcement systems, in particular to a carbon fiber grid reinforcement method. Background technique [0002] Building reinforcement is the use of carbon fiber, bonded steel, and high-pressure grouting to strengthen the building. This technology is widely used in design changes, adding beams, columns, cantilever beams, slabs and other reinforcement and modification projects. It is a connection technology that uses structural glue for post-reinforcing steel reinforcement in seismic reinforcement of building structures. It is the best choice for structural reinforcement and heavy load fastening applications. In the construction of reinforced concrete structures, the reinforced prefabricated beams of the slab and beam structure adjustment are repaired and planted. Anchoring of billboards for curtain wall embedded parts, and anchoring of planting bars for mechanical equipment installation, etc. Rock brick mas...
