What is the principle of CFRP composite strengthening?

the use of the carbon fiber adhesive, can work well, greatly improving the tensile strength of carbon fiber, the carbon fiber reinforcement must first make carbon fiber work together, so the adhesive on CFRP plays a key role, it is necessary to ensure the carbon filaments work together and work together to ensure that the carbon fiber cloth and structure, so as to achieve the objective of strengthening.

Increase the section reinforcement construction program

Increasing the cross-section reinforcement method for the traditional reinforcement construction method, the main method is applied to the beam stiffness, bending or shear capacity and the difference between the larger enough difference or the original column strength or stiffness of the reinforcement.

What should be paid attention to bonding CFRP fabric

Carbon fiber reinfroced polymer(CFRP) fabric is one of the commonly materials used in concrete reinforcement, and externally bonded carbon fiber reinfroced polymer(CFRP) is a new advanced mehod of concrete strengthening. The reinforcement of carbon fiber cloth can repair the structural cracks and improve the bearing capacity of the structure

The method of slab strengthening

Under the three circumstances, it is necessary to reinforce the slab: the bearing capacity of the slab is insufficient; the strength of the floor slab is unqualified; the slab is opening.

The basic principle of bridge reinforcement

Because of structural failure or damage, when it can not meet the requirements of structural safety or normal use, the bridge structure must be strengthened.6) The reinforcement design should be closely combined with the construction method, and take effective measures to ensure that the new and old structures are connected reliably and can work together.

The reasons for structural strengthening

With the development of construction industry, many buildings come into repair and strengthening period due to various diseases. What are the reasons for building reinforcement?

FRP strengthening or steel plate reinforcement

there are two advanced structural strengthening methods widely used, bonded steel plate reinforcement and FRP composite strengthening. The reinforcing principles of the two are similar: the structural glue is used to as a reinforcing material, externally bonded on the structure to form an integral structure, and work together

How to check the effect of CFRP reinforcement?

Carbon fiber fabric is a new advanced materials in building reinforcement engineering. Because of its excellent tensile strength, toughness, and acid and corrosion resistance, it has become one of the mainstream reinforcement methods. How to check the effect of CFRP reinforcement?

Rehabilitation and strengthening of existing buildings

Reinforcement of the existing buildings can be viewed from two aspects, one is the maintenance reinforcement due to the damage of the building, and the other is to reinforce the building in order to achieve a certain degree of destructiveness, such as eart

Concrete bridge reinforcement

Bridge reinforcement generally refers to the restoration and enhancement of the carrying capacity of an existing bridge through the reinforcement of components and the improvement of structural performance, in order to extend its service life and meet the
