TECHNICAL FIELD

[0002] In the field of building construction, there are various mature technical methods for the reinforcement of key structural components such as beams, slabs, columns, etc. The selection of these methods also needs to consider factors such as the specific condition of the structure, the extent of damage, and the reinforcement target. Traditional reinforcement methods include the addition of a steel reinforcement support system and the use of external steel plate reinforcement, etc. With the development of material technology, the use of carbon fiber cloth reinforcement, represented by the application of carbon fiber cloth, has been widely used due to its high efficiency and convenience. The carbon fiber cloth reinforcement method is to paste high-strength, lightweight carbon fiber cloth or glass fiber cloth and other composite fiber materials on the stress surface of the beam structure through high-performance structural adhesive. This process can effectively improve the carrying capacity of the structure and significantly enhance its seismic performance, making it an effective solution to address structural aging, insufficient carrying capacity, and other issues.

[0003] However, in the specific implementation of beam carbon fiber cloth reinforcement, the existing technical solutions have obvious limitations. For example, the reinforcement devices disclosed in patent documents "CN211473490U" and "CN118327342A" mainly focus on the pasting and laying of fiber cloth on the bottom surface of the beam. When reinforcement of the side wall of the beam is required, these devices cannot effectively cover the side wall, and manual operation by construction personnel is still required. This not only significantly increases the complexity and labor cost of construction, but also leads to a prolonged construction period and low efficiency.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1: This embodiment aims to provide a carbon fiber cloth building reinforcement device. Targeting the key reinforcement area of ​​the beam side wall, the device can achieve rapid bonding of the side wall and bottom surface of the U-shaped structure of the beam at the same time through the cooperation of various components, significantly improving construction efficiency and reducing manual labor intensity.

[0024] like Figures 1-7 As shown, the present embodiment provides a carbon fiber cloth building reinforcement device, comprising a feeding assembly 3, a traction and rolling assembly 4, a flip side pressure assembly 5 and a docking assembly 6. In actual application, the reinforcement device can be carried on the top of a scaffold, or installed on a liftable platform, and moved to the bottom of the target beam 1. Then, the carbon fiber cloth is transported to the right through the feeding assembly 3. After the traction and rolling assembly 4 clamps the cloth from the left starting position, it moves along the transverse transport track 7 formed by the joint of the transverse guide rail 41 and the horizontal flip guide rail 51 to the right side of the docking assembly 6 position, and reaches the end position. After being placed, it is relaxed and moved in the opposite direction to the bottom of the beam 1. After being received and clamped by the docking assembly 6, the flipping side pressure assembly 5 is started to control the 90-degree flipping action of the flipping guide rail 51 to fold the carbon fiber cloth toward the side wall of the beam 1. At this time, the flipping guide rail 51 is docked with the vertical guide rail 52 to form a vertical side pressure track 8. The side rollers on the left and right sides are controlled to move upward along the vertical side pressure track 8, so that the carbon fiber cloth is tightly pressed and adhered to the side wall of the beam; after completion, it is reset, and the reinforcement device is driven to move along the extension direction of the beam by mobile equipment such as scaffolding, and the moving seat 42 is controlled to start the next operation.

[0025] In specific structures, such asFigure 1 and 2 As shown, in this embodiment, the feeding assembly 3 includes a material rack 31, a conveying roller 32 and a cutting assembly 33, wherein the conveying roller 32 is rotatably mounted on the rack, the material rack 31 is arranged on the left side of the conveying roller 32, and the cutting assembly 33 is arranged on the right side of the conveying roller 32. In this embodiment, the cutting assembly 33 includes a mounting frame 331, a cutting cylinder 334, a cutting knife 332 and a base plate 333, wherein the base plate 333 is fixed in the middle of the mounting frame 331, the cutting cylinder 334 is fixed on the top of the mounting frame 331, and the output end of the cutting cylinder 334 extends vertically downward into the mounting frame 331, and the bottom thereof is fixedly connected to the cutting knife 332 by a vertical rod, and the cutting knife 332 is arranged parallel to the base plate 333. When the cutting cylinder 334 contracts, the cutting knife 332 forms a gap with the base plate 333 to allow the carbon fiber cloth to pass to the right. Furthermore, in order to ensure the reliability and smoothness of the carbon fiber cloth when it is transferred to the traction and rolling assembly 4, an auxiliary roller 34 can be set on the right side of the mounting frame 331. In this way, after the cutting knife 332 cuts the cloth, the auxiliary roller 34 can play a certain guiding role, so that the cut cloth will not sag naturally and flexibly, which will make it inconvenient for the mobile seat 42 to clamp and transport it.

[0026] In this embodiment, the feeding assembly 3 is configured such that the motor on the conveying roller 32 is controlled to rotate the roller, thereby feeding the carbon fiber cloth on the material rack 31 outward to between the cutting knife 332 and the bottom plate 333, and then conveying it outward to the traction member through the auxiliary roller 34. After the movable seat 42 of the traction and rolling assembly 4 moves to the end position, the cutting cylinder 334 is controlled to drive the cutting knife 332 to descend to perform the cutting operation on the carbon fiber cloth.

[0027] like Figure 3 and 4 As shown, in this embodiment, the traction and rolling assembly 4 includes a transverse guide rail 41, a clamping assembly 43 and a moving seat 42. Two sets of transverse guide rails 41 are fixed on the base 2 at intervals along the front and rear, and the moving seat 42 is reciprocatingly installed on the two transverse guide rails 41. In this embodiment, two sets of moving wheels are provided at the bottom of the moving seat 42 along the front and rear directions. The rotating shaft 438 of the moving wheel on one side is connected to the moving motor, and under the action of the moving motor, it moves back and forth left and right along the transverse guide rail (this is not described in detail in the prior art). The clamping assembly 43 is arranged on the moving seat 42 for actively clamping or releasing the carbon fiber cloth, and after release, the carbon fiber cloth can be tightly pressed against the bottom surface of the beam.

[0028] Further, if Figure 3As shown, the clamping assembly 43 in this embodiment includes a U-shaped seat 431, a rotating shaft 438, a lifting cylinder 432, a connecting rod 436, a clamping plate 433, a rolling plate 435, and a traction member. The U-shaped seat 431 is fixed on the top of the moving seat 42. The lifting cylinder 432 and the telescopic rod are respectively fixed on the front and rear side walls of the U-shaped seat 431. The rotating shaft 438 is rotatably installed in the U-shaped seat 431. The right side of the rolling plate 435 is located in the U-shaped seat 431 and is fixedly sleeved on the rotating shaft 438. By controlling the rotation of the rotating shaft 438, the rolling plate 435 can be flipped from the initial horizontal state to the vertical state to the right. The top of the rolling plate 435 is arc-shaped, which facilitates the pressing and adhering of the carbon fiber cloth on the bottom of the cross beam 1.

[0029] The end of the rotating shaft 438 adjacent to the lifting cylinder 432 extends out of the U-shaped seat 431. One end of the connecting rod 436 is hingedly connected to the rotating shaft 438, and the other end is perpendicularly fixed with a top block 439 which is columnar and protrudes outward. The clamping plate 433 is fixed on the lifting cylinder 432. A horizontal groove is formed on the side of the clamping plate 433 adjacent to the connecting rod 436. The top block 439 is slidably clamped in the horizontal groove. The traction member is fixed on the top of the lifting cylinder 432 and the telescopic rod. In this embodiment, the traction member includes a top plate 4371 and cylinder clamping jaws 4372. The top plate 4371 is fixed on the top of the lifting cylinder 432 and the telescopic rod. The cylinder clamping jaws 4372 are symmetrically fixed on the top plate 4371. The space between the front and rear cylinder clamping jaws 4372 is used for the carbon fiber cloth to pass through. The front and rear cylinder clamping jaws 4372 are stretched and contracted to clamp and release the front and rear sides of the carbon fiber cloth.

[0030] In actual application, when starting work, the moving seat 42 is located at the left starting position. At this time, the lifting cylinder 432 is in the extended state, driving the traction member to pop up, and the rolling plate 435 remains in the horizontal initial state. Then the cylinder clamping jaws 4372 are clamped on the front and rear edges of the right end of the carbon fiber cloth. The moving seat 42 carries the clamping assembly 43 to move to the right, conveying and laying the carbon fiber cloth to the right to the predetermined area on the bottom surface of the cross beam 1. After the carbon fiber cloth is conveyed to the docking assembly 6, the cylinder clamping jaws 4372 are released, and the moving seat 42 is controlled to reset to the left. In this process, the lifting cylinder 432 is retracted and lowered, driving the traction member and the cylinder clamping jaws 4372 to move downward as a whole. At the same time, the rolling plate 435 sleeved on the rotating shaft 438 is forced to flip 90 degrees from the horizontal state to the vertical state to the right through the connecting rod 436 mechanism. The arc-shaped edge structure designed on the top of the rolling plate 435 rolls, flattens, and compacts the released carbon fiber cloth and adheres it to the bottom wall of the cross beam 1, ensuring that it fully adheres to the concrete surface without bubbles or hollows.

[0031] The traction rolling assembly realizes the integrated operation process of forward clamping transportation and release and reverse rolling, replaces the traditional manual scraping and pressing, can apply more uniform and continuous pressure, effectively ensures the close adhesion of the carbon fiber cloth and the base material on the bottom surface of the beam, greatly reduces the quality defects such as poor adhesion, bubbles and wrinkles, significantly improves the compactness and adhesion strength of the reinforcing layer, and improves the construction efficiency.

[0032] As shown in Figure 5 The traction assembly is reset to the left below the beam 1, and the carbon fiber cloth on the left and right sides of the beam 1 is folded inward by using the turnover side pressing assembly 5 to be overlaid on the side wall of the beam 1. In the specific structure, the turnover side pressing assembly 5 is symmetrically arranged on the left and right sides of the horizontal moving guide rail 41, and the turnover side pressing assembly 5 includes a vertical moving guide rail 52, a turnover guide rail 51, a lifting seat 53 and a side pressing roller 55. Taking the turnover side pressing assembly 5 located on the right side of the horizontal moving guide rail 41 as an example, the left side of the turnover guide rail 51 is hinged to the base 2 and is turned over by a turnover motor. The adjacent ends of the left and right turnover guide rails 51 and the horizontal moving guide rail 41 are respectively connected to form a horizontal transportation track 7.

[0033] Further, in the embodiment, the two groups of turnover guide rails 51 are arranged on the base 2 in the front-rear direction, and a turnover shaft 438 is rotatably installed between the front and rear turnover guide rails 51. One end of the turnover shaft 438 is drivingly connected to the turnover motor, and the two turnover guide rails 51 are simultaneously driven to turn over 90 degrees under the action of the turnover motor. In the embodiment, the adjacent ends of the horizontal moving guide rail 41 and the turnover guide rail 51 are arc-shaped and connected, so that when the horizontal moving guide rail 41 and the turnover guide rail 51 are connected together to form the horizontal transportation track 7, the stability of the moving seat 42 moving back and forth along the horizontal transportation track 7 is ensured. A rectangular groove is formed in the base 2 at the connection position of the horizontal moving guide rail 41 and the turnover guide rail 51. When the turnover guide rail 51 is driven to rotate 90 degrees, the left end thereof is rotated downward into the rectangular groove, so that an avoiding channel 59 is formed between the hinge point of the turnover guide rail and the right end of the horizontal moving guide rail 41, and the left end of the turnover guide rail is connected with the vertical moving guide rail 52, thereby forming a vertical side pressing track 8 to provide track support for the upward and downward movement of the lifting seat 53 and the side pressing roller 55.

[0034] Specifically, as shown in Figure 5As shown, the vertical moving guide rail 52 is fixed on the base 2 through the support seat 58 in the vertical direction, the lifting seat 53 is slidingly installed on the vertical moving guide rail 52, the outer side wall of the lifting seat 53 is fixed with the rack 56 respectively, the support seat 58 is fixed with the driving motor 57, the output shaft of the driving motor 57 is fixed with the gear, the gear is engaged with the rack 56 to drive the lifting seat 53 to reciprocate up and down along the vertical moving guide rail 52. The inner side of the front and rear adjacent lifting seats 53 is fixed with the compression roller frame 54, the compression roller frame 54 is rotatably sleeved with the side compression roller 55, and the inner side of the side compression roller 55 is in the same plane with the side wall of the cross beam 1, so that it can move up and down along the side wall of the cross beam 1 to compress and paste the carbon fiber cloth on the side wall of the cross beam 1.

[0035] In the embodiment, the setting of the turnover side compression assembly 5, the turnover motor drives the turnover shaft 438 to rotate, drives the two groups of turnover guide rails 51 arranged at intervals to turn 90 degrees around the left hinge point, so that the left end of the turnover guide rail 51 rotates downward into the preset rectangular groove in the base 2, forms an avoiding channel 59 for the lifting seat 53 and the side compression roller 55 to move up and down between the hinge point and the right end of the horizontal moving guide rail 41, until the left end of the turnover guide rail 51 is connected with the vertical moving guide rail 52, so as to jointly form a continuous vertical side compression track 8, after the conversion of the track form is completed, the lifting seat 53 is driven by the driving motor 57, the gear and the rack 56 transmission system to simultaneously drive the side compression roller 55 to reciprocate up and down along the vertical side compression track 8.
