Device for reinforcing concrete beam through fiber cloth and construction method thereof

Abstract

The invention belongs to the technical field of civil engineering structure reinforcement and transformation construction, and particularly relates to a device for reinforcing a concrete beam through fiber cloth and a construction method thereof. The device comprises a roller frame provided with a pressing roller and adjusting supports, supporting rods are vertically arranged on the two sets of adjusting supports located on the two sides of the roller frame in a guiding fit mode, longitudinal adjusting wheels or limiting pins horizontally extend from the top ends of the supporting rods to the upper surface of the concrete beam, and therefore, the fiber cloth is pressed on the lower surface of the concrete beam through clamping cooperation of the longitudinal adjusting wheels or the limiting pins and the pressing rollers. The device further comprises a longitudinal adjusting assembly capable of enabling the supporting rod to generate vertical adjusting and positioning actions relative to the adjusting support. The device has the advantages of being easy and convenient to operate, high in reinforcing efficiency and good in finished product quality, time and labor are saved, and the actual construction period can be effectively shortened. The invention further provides a construction method applying the device, so that the purpose of on-site rapid construction of the fiber cloth is achieved specifically.

Description

technical field [0001] The invention belongs to the technical field of civil engineering structure reinforcement and renovation construction, and in particular relates to a device for reinforcing concrete beams with fiber cloth and a construction method thereof. Background technique [0002] Due to structural aging, change of use, etc., more and more concrete components need to be reinforced to improve their durability or ultimate bearing capacity. The most common method is fiber cloth reinforcement. Fiber cloth has a high strength-to-weight ratio, good fatigue resistance and excellent corrosion resistance, and has become one of the main reinforcement materials for concrete members. The fiber cloth reinforcement method requires the use of glue with high bonding strength, and the fiber cloth is tightly attached to the surface of the concrete member, so that the fiber cloth and the concrete member can be tightly combined and work together to enhance the concrete member. load ...

AI Technical Summary

Problems solved by technology

Concrete beams are one of the representative structures of concrete components. When fiber cloth is used to strengthen concrete beams, the fiber cloth is glued and pasted on the lower surface of the square beam, and several layers are pasted layer by layer; in the prior art, usually It is manually pasted layer by layer without tools, which is not only time-consuming and laborious, but also the accuracy of the paste is doubtful, resulting in unsatisfactory reinforcement efficiency and quality, which needs to be solved urgently
