Description

Technical Field

[0001] This invention relates to the field of structural high-strength fiber cloth reinforcement technology, specifically to an operating device for discontinuous reinforcement of existing structures. Background Technology

[0002] Reinforced concrete beams and columns, as commonly used structural components, are widely applied in various aspects of building structures. However, due to factors such as prolonged use, improper maintenance, and changes in functional requirements, the load-bearing capacity of some reinforced concrete beam-column joints may no longer meet the requirements for use and seismic resistance. With the increasing maturity of concrete reinforcement technology and the growing demand for functional use within buildings, reinforcement of the original structure is necessary. The traditional construction process for high-strength fiber cloth is as follows: cleaning and repairing the concrete substrate—applying primer—cutting the high-strength fiber cloth—adhering the high-strength fiber cloth—squeezing out air bubbles and leveling—surface finishing or fireproofing treatment.

[0003] The existing method of bonding high-strength fiber cloth is done manually, which requires construction workers to work for a long time, is slow, involves many steps, and has low work efficiency. Therefore, there is a need for an existing discontinuous reinforcement device to improve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an operating device for discontinuous reinforcement of existing structures to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An operating device and construction method for discontinuous reinforcement of existing structures are disclosed, comprising a vehicle body, a rotating shaft rotatably mounted inside the vehicle body, a rotating arm fixedly mounted on the surface of the rotating shaft, a pressure roller rotatably mounted at one end of the rotating arm, a cutting mechanism fixedly mounted inside the vehicle body, cylinders one mounted on both sides inside the vehicle body, the other end of cylinders one being hinged to the rotating arm, the cutting mechanism comprising: cylinder two fixedly mounted inside the vehicle body, a lower cutting blade fixedly mounted at one end of cylinder two, and an upper cutting plate fixedly mounted inside the vehicle body corresponding to the lower cutting blade.

[0007] As a preferred embodiment of the present invention, the interior of the vehicle body is provided with a high-strength fiber cloth placement groove, and a feeding roller is provided inside the high-strength fiber cloth placement groove.

[0008] As a preferred embodiment of the present invention, a plurality of rollers are fixedly provided at the lower end of the vehicle body.

[0009] As a preferred embodiment of the present invention, a handrail is fixedly provided on one side of the vehicle body.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. In this invention, high-strength fiber cloth is released by the feeding roller and laid on the bottom of the floor slab or beam. The first cylinder is started to drive the rotating arm to rotate through the rotating shaft, thereby indirectly driving the pressure roller to press the high-strength fiber cloth. At this time, the pressure roller is pushed and the roller moves to continuously pull out the high-strength fiber cloth and press it through the pressure roller. Then, the second cylinder is started to drive the lower cutting blade to move up and cooperate with the upper cutting plate to cut the high-strength fiber cloth. The device has a simple structure and high working efficiency. Attached Figure Description
