Reinforce the communication room

Project Overview

The building is a frame structure. It is now transformed from an office building into a communication computer room. The function changes and the load changes. Therefore, carbon fiber reinforced polymer is used for reinforcement to improve the building's carrying capacity.

The project started in September 2016 and has now been completed. The material used for the reinforcement is the carbon fiber cloth provided by Horse Company. The amount of carbon cloth is about 13,000 square meters and the corresponding amount of carbon cloth impregnated glue, the reinforcement effect is good.

Project information

Owner: Shanghai Stock Exchange;

Main structural reinforcement materials: carbon fiber cloth 13,000 square meters and carbon cloth impregnated rubber;

Construction time: September 2016.

Reinforcement reasons

It is mentioned in the project profile that the building was originally an office building, and it is now transformed into a communication room. The load has increased significantly, and the carbon fiber is now used to reinforce the beams and slabs to increase the tensile strength, so as to achieve the load conditions for the functional conversion of the building. The carbon cloth reinforcement method is used to reinforce the building according to the design requirements of the design institute.

Reinforcement plan

The surface of the beam and plate members can be strengthened by bonding carbon fiber cloth to increase the tensile strength of the beam and the bottom of the plate. Similarly, the cracks in the beam or plate can be prevented from further deterioration to achieve the purpose of enhancing the bearing capacity of the structure.

Strengthening effect

1. The cracks on the beams and plates were effectively controlled to continue to increase, and the cracks were repaired to a certain extent;

2. After the carbon fiber reinforcement is completed, the weight of the main body has hardly increased, and the indoor space is not affected;

3. Effectively improve the bearing capacity of beams and slabs after CFRP reinforcement, and meet the requirements of structural function transformation;
