Description

CFRP plate horizontal direction secondary adjustment tensioning construction method and system

Technical Field

The utility model belongs to the technical field of reinforcement of external prestressing force applied in civil engineering, and particularly relates to a construction method and a system for secondarily adjusting and tensioning CFRP plates along the transverse direction.

Background

The concrete structural member or the steel structural member in engineering structures of modern buildings, traffic, bridges and the like has huge potential safety hazards due to the conditions of insufficient bearing capacity or cracking and the like caused by environmental corrosion, material aging, change of structural functions and the like or natural disasters.

The existing reinforcement methods for engineering components are divided into two major categories from the principle of action, namely a passive reinforcement method and an active reinforcement method. Passive reinforcement refers to directly adding tensile (or shear) reinforcing materials in the tensile (or shear) weak area of a member, for example: and (3) sticking a steel plate, sticking a high-strength fiber composite material (carbon fiber and aramid fiber) and the like. The reinforcing material only bears the internal force caused by the live load and the post-load, and compared with the original stressed member, the strain (stress) of the reinforcing material is relatively lagged. In particular, the scheme of directly sticking high-strength fiber composite materials is adopted, so that the high tensile property of the reinforcing material is difficult to play a role. Therefore, the passive reinforcement method cannot reduce the deformation of the original structure and cannot close the crack. Active reinforcement refers to the application of a pre-stress to a reinforcing material disposed in a region of tension (or shear) weakness of a member. The reinforcing material is actively stressed, so that the problem of strain (stress) hysteresis of the post-reinforcing material is fundamentally solved, the high tensile property of the reinforcing material can be fully exerted, the utilization efficiency of the material is improved, and the bending-resistant bearing capacity and the normal working performance of the reinforced member are both obviously improved.

The active reinforcement method is necessarily applied to a matched tensioning system, for example, chinese patent application ZL202010702249.2 discloses a tensioning and anchoring device of a prestressed CFRP plate reinforcing beam and a using method thereof, wherein the tensioning and anchoring device comprises a CFRP plate, an anchoring assembly and a tensioning assembly; the tensioning assembly comprises a tensioning smooth bore, a second clamp, a limiting plate and a tensioning mechanism; the contact surfaces of the expansion plate and the second clamp are provided with saw teeth with opposite directions. According to the CFPR plate, the two groups of clamps fixedly clamped at the two ends of the CFRP plate are arranged in the two groups of sliding bores to apply prestress, so that the eccentricity of the tensioning force can be prevented, the self-locking of the CFPR plate after the prestress is applied is realized through the mutual cooperation of the saw teeth between the telescopic plate and the second clamp, and the retraction of the CFPR plate is limited.

In the use of the patent, although the CFPR plate is mechanically clamped by the clamp, the anchoring efficiency is high, the quality performance is stable, the high-strength performance of the CFRP plate can be fully exerted, the jack can be dismantled after the prestress is applied, the integrated design and the simple operation process are realized, and the working efficiency is improved, but the prestress can not be secondarily adjusted after the construction is finished, if the prestress is reduced after many years, or the prestress does not meet an ideal value after the construction, the tensioning adjustment is needed again, and meanwhile, when the reinforcing material with larger eccentricity is arranged, the shearing resistance of the CFRP plate is poor, and when the external force perpendicular to the plane of the CFRP plate is applied, the carbon fiber reinforced composite material is easy to brittle fracture, so that the negative bending moment provided for the structural member to be reinforced is very limited, and the technical problem of mid-span downwarping of the structural member to be reinforced cannot be effectively solved.
