Load increase strengthening of beam and slab

Project overview

The project is reinforced for the bathrooms of the Huaian power plant. Due to the increase of load on the two floor (roof change), some boards and beams need to be reinforced. The design institute adopts the method of carbon fiber reinfroced polymer(CFRP) reinforcement to reinforce the structure, so that it can meet the normal use of buildings and the requirements of aseismic structures.

A brief introduction to the strengthening technology of carbon fiber fabric

The reinforcement and reconstruction of CFRP is a technology that is now widely used in the world. It can be widely used in the reinforcement of various building structures. It has many advantages compared with the traditional method of reinforcement.

The strengthening technology of carbon fiber structure refers to the use of high performance binder to paste carbon fiber cloth on the surface of structural components, so that both of them work together to improve the bearing capacity of structural members (flexural and shear), thus strengthening and reinforcing the building materials.

The use of CFRP reinforcement has the following advantages:

A, the strength is high, the effect is good.

B and strengthening can greatly improve the corrosion resistance and durability of the structure.

C, light weight, basically does not increase the structural weight and section size; good flexibility, easy to cut, wide range of adaptation.

D, simple construction (no need for large construction machinery and turnover materials), easy operation and good economy.

E, the construction period is short. Therefore, the carbon fiber structure reinforcement technology has a great effect on the concrete structure.

Carbon fiber reinforcement technology is suitable for the reinforcement and repair of various structural types and various structural parts, such as beams, plates, columns, roof frames, bridge piers, bridges, barrels, shells and so on. The strength of concrete at the base level is not less than C1 5. In addition, some mechanical properties of brick masonry can be reinforced with carbon fiber.
