Abstract

The invention discloses a tensioning and anchoring device for a beam reinforced with a prestressed CFRP plate and a method for using the same. ; There are sawtooths facing oppositely on the contact surfaces of the telescopic plate and the second fixture. In the present invention, two sets of clamps fixedly clamped at both ends of the CFRP plate are installed in two sets of smooth bores to apply prestress, which can prevent the eccentricity of the tension force, and achieve this by cooperating with the saw teeth between the expansion plate and the second clamps. It ensures the self-locking of the CFPR plate after the prestress is applied, and limits the retraction of the CFPR plate. The CFPR plate is mechanically clamped by the fixture, which has high anchoring efficiency and stable quality and performance, and can give full play to the high-strength performance of the CFRP plate. The jack can be removed after the prestress is applied. The integrated design and easy operation process improve the work efficiency.

Description

technical field [0001] The invention relates to the technical field of beam tensioning and anchoring, in particular to a tensioning and anchoring device for beams reinforced with prestressed CFRP plates and a method for using the same. Background technique [0002] A large number of concrete beams of engineering structures such as industrial and civil buildings, traffic bridges, etc., due to environmental erosion, material aging, and changes in structural functions, the load they can bear changes, and the occurrence of natural disasters and human disasters leads to insufficient bearing capacity or cracks, etc. , there is a very large potential safety hazard, so it is necessary to strengthen and repair it. [0003] CFPR (carbon fiber) plate is a new type of reinforcement material. With the continuous maturity of prestressing technology, the use of prestressed CFRP plate to strengthen the concrete structure in active service has been widely used, which improves the bending and...
