Carbon fiber reinforced structure and construction method

Abstract

The invention provides a carbon fiber reinforcement structure and a construction method and belongs to the technical field of seismic strengthening. The carbon fiber reinforcement structure comprises an original masonry wall, a prefabricated round-hole floor slab and a carbon fiber cloth member, wherein the carbon fiber cloth member comprises a carbon fiber pull rod in the middle, a spreading area and a sticking area, and the spreading area and the sticking area are located at two ends. The carbon fiber pull rod is formed by rolling carbon fiber cloth, then dipping the carbon fiber cloth with gum and performing curing, the original masonry wall or a ring beam is drilled, the carbon fiber pull rod penetrates through the hole, the spreading area and the sticking area which are exposed on two sides are respectively spread and then stuck to a corner oblique plane area and the lower surface of the prefabricated round-hole floor slab, and the through-long carbon fiber covering cloth is stuck onto the sticking area so as to ensure firm carbon fiber cloth sticking. Due to the fact that the tensile resisting capacity of carbon fiber is good, a technique of sticking the carbon fiber to the surface of concrete is mature and reliable, and the carbon fiber reinforcement structure has characteristics of abiding by regulations in conduction and inspection and the advantages of being simple, convenient and quick to construct, low in construction cost and the like and has wide application prospect.

Description

technical field [0001] The invention relates to a carbon fiber reinforced structure and a construction method, belonging to the technical field of seismic reinforcement. Background technique [0002] Previous earthquake damage investigations have proved that the collapse of many brick-concrete structures is due to the unreliable connection between the prefabricated reinforced concrete round-hole floor slab and the supporting brick wall (beam), the length of the support is not enough or there is no tie with the wall (beam), and the earthquake shakes In this case, the floor slab breaks away from the supporting walls (beams), causing the floor slab to collapse, causing the entire building to collapse. In particular, many of the existing brick-concrete building floors in my country use prefabricated round-hole slabs, and most of the support lengths and structural connections of the slabs do not meet the seismic requirements. In order to eliminate potential safety hazards, reinfo...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problem that the overlapping length of the prefabricated round hole plate on the wall does not meet the requirements of the current specification in the masonry structure house where the prefabricated round hole plate is connected with the wall, the present invention proposes a carbon fiber reinforced structure and a construction method, so that It meets the requirements of seismic construction

It solves the problems of long construction period and increased floor load of the existing reinforcement method, and enhances the connection strength between the prefabricated circular hole floor and the supporting wall (beam).
