Description

Technical Field

[0001] This invention relates to the field of building structure reinforcement technology, specifically a reinforcement device for frame beams in civil engineering. Background Technology

[0002] As a core force-transferring component of modern architecture, a frame beam specifically refers to a beam that forms a two-way beam-column lateral force resisting system with frame columns or shear walls through rigid joints. When using a steel frame structure, H-beams or box sections are often selected, while concrete frame beams are cast-in-place monolithic structures. This component directly bears the vertical loads (including dead loads and live loads) of the floor and roof and transfers them to the vertical load-bearing components (columns / walls). At the same time, relying on the beam-column collaborative working mechanism, it coordinates and resists horizontal lateral forces such as wind loads and seismic actions. Through the special construction of spatial rigid joints, a structural system with overall stiffness is formed, which not only ensures the balance of the stiffness distribution in the building space, but also effectively reduces the impact of uneven foundation settlement on the superstructure, realizing the dual functional coupling of vertical force transmission and horizontal resistance.

[0003] Concrete frame beams are prone to structural defects during construction due to factors such as material performance degradation, long-term load application, or improper construction techniques. These defects manifest as concrete cracking, insufficient cross-sectional bearing capacity, or decreased stiffness. Carbon fiber reinforcement technology is needed to restore their mechanical properties. Traditional reinforcement methods involve manually laying carbon fiber cloth, which presents several problems in practice. First, construction workers must continuously lay the cloth on multiple surfaces, including the bottom and sides of the beam, leading to frequent adjustments to scaffolding or lifting equipment and low work efficiency. Especially during the manual rolling stage, the varying angles of the work surface can cause fluctuations in rolling pressure, resulting in localized wrinkles between the fiber cloth and the concrete substrate, uneven adhesive distribution, and other quality issues. Furthermore, unexpelled air bubbles can form voids after curing, severely affecting the synergistic stress-bearing effect between the carbon fiber cloth and the beam. Therefore, we propose a reinforcement device for civil engineering frame beams. Summary of the Invention

[0004] One of the technical problems this application aims to solve is that construction workers need to continuously lay fiber cloth on multiple sides of the beam, and the frequent adjustment of scaffolding or lifting equipment leads to low work efficiency. Especially in the manual rolling stage, the variable angle of the construction surface can easily cause fluctuations in the rolling pressure, resulting in quality problems such as local wrinkles and uneven distribution of adhesive between the fiber cloth and the concrete base. In addition, air bubbles that are not fully expelled will form hollows after curing, which seriously affects the cooperative stress-bearing effect between the carbon fiber cloth and the beam.

[0015] The present invention has at least the following beneficial effects:

[0016] 1. Through the linkage design of the reinforcement laying unit and the laying frame, the carbon fiber cloth is continuously laid along the three-dimensional contour of the frame beam, avoiding positioning deviation and intermittent construction defects caused by manual operation. At the same time, the three-dimensional driving system can accurately match the geometry of the beam, eliminate the weak joint area caused by traditional segmented pasting, and improve the overall structure. Finally, the three-dimensional contour driving function can be adapted to irregular beams such as arc and variable cross-section, which can effectively improve the applicability of the device.

[0017] 2. The roller pressing fusion unit actively removes air bubbles trapped at the interface between the fiber cloth and the beam through negative pressure adsorption, significantly reducing the void rate and ensuring a uniform and dense adhesive layer. Through the synergistic effect of the negative pressure hole array and dynamic rolling, a negative pressure environment is formed to force the gas out, avoiding the formation of stress concentration sources after the adhesive layer cures. At the same time, the negative pressure field drives the adhesive to directionally fill the gaps between the carbon fiber bundles, ensuring full bonding of the resin, fiber, and substrate at the multidimensional interface. The negative pressure adsorption force overcomes the surface tension of the adhesive and the capillary resistance of the substrate, promoting the penetration of the resin into the fiber interior and concrete pores.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-12 andFigure 14 This invention provides a technical solution: a reinforcement device for a frame beam in civil engineering, comprising a movable frame 1 and a construction platform 2, wherein the movable frame 1 has a lifting function, and the construction platform 2 is equipped with a plurality of laying frames 3 for fixing carbon fiber cloth rolls, and a rolling roller 4 is rotatably mounted on the laying frame 3. The surface of the rolling roller 4 is arranged with a plurality of negative pressure holes 41 in a circumferential array, and a reinforcement laying unit 5 connected to the laying frame 3 is provided on the construction platform 2 to drive the laying frame 3 to continuously lay carbon fiber cloth U-shaped hoops along the three-dimensional contour of the frame beam. The reinforcement laying unit 5 is equipped with a roller pressing fusion unit 9 connected to the rolling roller 4 to remove air bubbles between the fiber cloth and the beam body interface through negative pressure adsorption during the laying of carbon fiber cloth, and simultaneously drive the adhesive to penetrate directionally into the gaps between the carbon fiber bundles.

[0035] The reinforcement laying unit 5 includes a guide 6 set on the construction platform 2, which guides the laying frame 3 to move. A power component 7 is set on the guide 6 to provide power for the operation of the guide 6. A fixing component 8 is set on the guide 6 to fix the laying frame 3.

[0036] The guide component 6 includes a support plate 61 mounted on the construction platform 2. A guide plate 62 is mounted on the support plate 61. A guide groove 63 is formed on the guide plate 62. Movable grooves 64 are formed on both sides of the guide groove 63. A movable block 65 is slidably mounted in the guide groove 63. A sliding rod 66 is provided on both sides of the movable block 65. The sliding rod 66 passes through the movable groove 64 and is slidably connected to the movable groove 64. A plurality of locking rods 67 are provided at the end of the sliding rod 66 away from the movable block 65. The locking rods 67 are slidably connected to the guide plate 62.

[0037] During the laying of carbon fiber cloth, the guide groove ensures that the moving block 65 connected to the laying frame 3 can only move the laying frame 3 along a fixed path. At the same time, the sliding rod 66 and the locking rod 67 ensure that the laying frame 3 remains stable during movement. The guide groove provides a one-way degree of freedom constraint on the linear sliding of the moving block 65, eliminating the risk of path deviation caused by manual operation. Meanwhile, the composite guide system formed by the sliding rod 66 and the locking rod 67 uses multiple contact points to balance and suppress the device sway caused by construction vibration, thereby improving the stability of carbon fiber cloth laying. Moreover, the carbon fiber cloth is continuously laid along the three-dimensional contour of the frame beam, avoiding positioning deviations and intermittent construction defects caused by manual operation. At the same time, the three-dimensional driving structure can accurately match the geometry of the beam, eliminating weak joint areas caused by traditional segmented pasting and improving the overall structural integrity.

[0038] The power component 7 includes two mounting plates 71 mounted on the construction platform 2, with the two mounting plates 71 located on both sides of the guide plate 62. The mounting plates 71 are provided with guide grooves 72. Rotating rods 73 are rotatably mounted on both sides of the moving block 65. A double-headed motor 74 is installed inside the moving block 65. The power shafts at both ends of the double-headed motor 74 are connected to the rotating rods 73. One end of the rotating rod 73 passes through the guide grooves 72 and is movably connected to the guide grooves 72. A moving gear 75 is provided on the end of the rotating rod 73 away from the double-headed motor 74. Push plates 76 are provided on each of the mounting plates 71. Moving teeth 77 that mesh with the moving gears 75 are provided on the push plates 76.

[0039] When movement is required, the dual-head motor 74 first operates, driving the rotating rods 73 on both sides to rotate. The rotation of the rotating rods 73 drives the moving gears 75 set at both ends to rotate. When the moving gears 75 rotate, they mesh with the moving teeth 77 on the push plate 76 and move under the push of the moving teeth 77, thereby driving the moving block 65 to move in the guide groove. The dual-head motor 74 drives the symmetrically distributed rotating rods 73 to rotate synchronously. Combined with the meshing transmission mechanism of the moving gears 75 and the moving teeth 77 on the push plate 76, a bidirectional self-balancing power output system is formed. Its core beneficial effect is: to realize the high-precision linear displacement of the moving block 65 in the guide groove by utilizing the rigid transmission characteristics of gear and rack meshing; to eliminate the torque offset caused by single-sided drive by the symmetrical layout of the dual motors; to ensure the synchronicity and stability of power transmission during the movement of the carbon fiber cloth laying frame 3; to maintain the constant contact pressure between the laying device and the beam interface in complex construction scenarios; and to overcome the process defects such as fiber cloth wrinkles and uneven adhesive layer thickness caused by transmission gaps or path deviations in traditional drive structures.

[0040] The fixing component 8 includes a fixing plate 81 mounted on the movable block 65. An adjusting screw 82 is rotatably mounted on the fixing plate 81. A lifting rod 83 is mounted on the adjusting screw 82 and threadedly connected to the adjusting screw 82. A circular plate 84 is mounted on the lifting rod 83. A telescopic rod 85 is mounted on the circular plate 84, and one end of the telescopic rod 85 is connected to the fixing plate 81. A limiting plate 86 is mounted at the top of the lifting rod 83. A second telescopic rod 87 is mounted on the limiting plate 86. The top of the second telescopic rod 87 is connected to the laying frame 3. A buffer spring 88 is sleeved on the second telescopic rod 87.

[0041] The vertical height of the carbon fiber cloth laying frame 3 is precisely adjusted by adjusting the threaded engagement between the lead screw 82 and the lifting rod 83. Combined with the elastic deformation compensation mechanism of the telescopic rod 85 and the buffer spring 88, the mechanical vibration and external load impact are dynamically balanced during construction. The rigid guiding structure of the limiting plate 86 and the telescopic rod 87 ensures that the displacement trajectory of the laying frame 3 in three-dimensional space is precisely controllable. At the same time, the buffer spring 88 absorbs instantaneous overload energy through its elastic energy storage characteristics, maintaining a constant contact pressure between the fiber cloth and the beam surface. This effectively solves the quality problems caused by insufficient rigidity in traditional processes, such as fiber cloth wrinkles, uneven adhesive layer thickness, and interface hollowness.

[0042] The roller pressing and fusion unit 9 includes a roller pressing component 10 disposed on the laying frame 3, which compresses the laid carbon fiber cloth. The roller pressing component 10 is provided with a negative pressure component 11, which sucks out air bubbles between the fiber cloth and the beam interface. The laying frame 3 is provided with a cleaning component 12, which cleans the roller pressing roller 4.

[0043] The roller pressing component 10 includes a rotating shaft 101 rotatably mounted on the laying frame 3, the rotating shaft 101 being connected to the roller pressing roller 4, a pneumatic chamber 102 being provided on the laying frame 3, and the rotating shaft 101 passing through the pneumatic chamber 102 and being rotatably connected to the pneumatic chamber 102, the pneumatic chamber 102 being rotatably connected to the roller pressing roller 4, the pneumatic chamber 102 having a connecting hole 103 for use with the negative pressure hole 41, a negative pressure chamber 104 being provided inside the pneumatic chamber 102, the negative pressure chamber 104 having a plurality of through holes 105 for use with the negative pressure hole 41 and the connecting hole 103, and a rubber sleeve 106 being fitted on the roller pressing roller 4.

[0044] The negative pressure component 11 includes a compression chamber 111 disposed on the negative pressure chamber 104. A piston plate 112 is slidably disposed inside the compression chamber 111. A compression rod 113 is disposed on one side of the piston plate 112 and slidably connected to the compression chamber 111. A plurality of arc-shaped push blocks 114 that cooperate with the compression rod 113 are disposed circumferentially on a section of the rotating shaft 101 located inside the pneumatic chamber 102. A compression spring 115 is disposed inside the compression chamber 111. One end of the compression spring 115 is connected to the piston plate 112. A one-way air inlet valve 116 is disposed inside the compression chamber 111, and the compression chamber 111 is connected to the negative pressure chamber 104 through the one-way air inlet valve 116. A one-way exhaust valve 117 is disposed at the bottom of the compression chamber 111, and the compression chamber 111 is connected to the pneumatic chamber 102 through the one-way exhaust valve 117.

[0045] During the movement of the laying frame 3, the rolling roller 4 contacts the carbon fiber cloth under pressure and rolls the laid carbon fiber cloth. Simultaneously, as the laying frame 3 continues to move, the rolling roller 4 also rotates. During this rotation, the rolling roller 4 drives the rotating shaft 101 to rotate synchronously. When the rotating shaft 101 rotates, one end of it located inside the pneumatic chamber 102 drives the pushing block 114 to rotate synchronously. During this rotation, the pushing block 114 pushes the extrusion rod 113 downwards, causing the extrusion rod 113 and piston plate 112 to move within the extrusion chamber 111, thus discharging gas into the pneumatic chamber 102 through the one-way exhaust valve 117. The gas discharged into the pneumatic chamber 102 is discharged through the connecting hole 103 (not connected to the through hole 105) into the negative pressure hole 41 (not in contact with the carbon fiber cloth), and then discharged through the negative pressure hole 41. During discharge, a small amount of colloid sucked into the negative pressure hole 41 is expelled, thus preventing blockage of the negative pressure hole 41. When the push block 114 disengages from the extrusion rod 113, the piston plate 112 will reset under the elastic force of the extrusion spring 115. During the reset process of the piston plate 112, a negative pressure is generated in the extrusion chamber 111, thereby drawing the gas in the negative pressure chamber 104 into the extrusion chamber 111 through the one-way air inlet valve 116. When the roller 4 rotates, the negative pressure hole 41 on the side in contact with the carbon fiber cloth will connect with the negative pressure chamber 104 under negative pressure through the connecting hole 103 that communicates with the through hole 105. At this time, the connected negative pressure hole 41 generates negative pressure, which draws the air bubbles between the carbon fiber cloth and the beam interface, thereby achieving the purpose of venting the gas. At the same time as the negative pressure draws the air bubbles, the adsorption force generated by the negative pressure field will overcome the surface tension of the adhesive and the capillary resistance of the substrate, promote the resin to penetrate into the fiber interior and the concrete pores, and make the adhesive directionally fill the gaps between the carbon fiber bundles, ensuring that the resin, fiber, and substrate are fully bonded to the multidimensional interface.

[0046] The rotating shaft 101 drives the arc-shaped push block 114 to periodically drive the piston plate 112 to reciprocate, forming a continuous pulsating negative pressure adsorption force. This adsorption force is transmitted to the carbon fiber cloth-beam interface through the pneumatic chamber 102 and the negative pressure hole 41, forcibly removing trapped air bubbles and simultaneously driving the adhesive to directionally penetrate into the gaps between the fiber bundles and the capillary pores of the concrete substrate, achieving three-dimensional reinforcement of the interface wetting. At the same time, the elastic covering design of the rubber sleeve 106 adaptively compensates for the unevenness of the substrate during the rolling process, ensuring that the negative pressure adsorption force is evenly distributed. This solves the problems of hollow defects and uneven adhesive penetration caused by incomplete venting in traditional processes, significantly improving the interface bonding integrity and structural durability of the reinforcement layer.

[0047] The cleaning component 12 includes a collection pipe 121 mounted on the laying frame 3. A scraper 122 is mounted on the collection pipe 121, and the scraper 122 abuts against a rubber sleeve 106 fitted on the roller 4. A rotating shaft 123 is rotatably mounted inside the collection pipe 121. One end of the rotating shaft 123 passes through the collection pipe 121 and the laying frame 3. A spiral blade 124 is mounted on the rotating shaft 123 and slidably connected to the inner wall of the collection pipe 121. A power rod 125 connected to the rotating shaft 101 is rotatably mounted on the laying frame 3. Both the power rod 125 and the rotating shaft 123 are equipped with power pulleys 126. A power belt 127 is mounted on the power pulleys 126. A collection chamber 128 is mounted on the laying frame 3 and communicates with the collection pipe 121.

[0048] When the roller 4 rotates, the part that is not in contact with the carbon fiber will come into contact with the scraper 122. Under the action of the scraper 122, the colloid discharged from the negative pressure hole 41 is peeled off from the roller 4. The peeled colloid will fall into the collection pipe 121. When the roller 4 rotates, it will drive the power rod 125 to rotate, which will drive the rotating shaft 123 to rotate through the power pulley 126 and the power belt 127. The rotation of the rotating shaft 123 will drive the spiral blade 124 to rotate, thereby discharging the colloid that has fallen into the collection pipe 121 into the collection chamber 128. The scraper 122 scrapes off the colloid by contacting the rubber sleeve 106 on the roller 4. Combined with the axial conveying function of the spiral blade 124, the colloid is returned to its original state. The system utilizes mechanical linkage to achieve real-time peeling and directional collection of residual adhesive on the surface of the roller 4. The elastic contact design between the scraper 122 and the rubber sleeve 106 ensures efficient removal of adhesive overflow from the negative pressure hole 41 without damaging the roller surface. The peeled adhesive is introduced into the conveying channel of the spiral blade 124 through the collection pipe 121. The rotating shaft 123 driven by the power pulley 126 drives the spiral blade 124 to rotate continuously, forcibly conveying the adhesive to the collection chamber 128 for centralized storage. This effectively avoids the problem of adhesive dripping and contaminating the work surface in traditional construction, while maintaining the unobstructed flow of the negative pressure hole 41 of the roller 4, ensuring the continuous and stable operation of the bubble suction and adhesive penetration functions, and improving construction efficiency and environmental protection.

A return spring 8 is sleeved on the push rod 14 between the locking plate 17 and the positioning plate 13 in contact with the adhesive plate 15. An L-shaped plate 19 is provided on the laying frame 3. A telescopic rod 20 is provided on the L-shaped plate 19. An extrusion block 21 is slidably connected to the laying frame 3 on the telescopic rod 20. The extrusion block 21 is a wedge-shaped block, and the inclined surface of the wedge-shaped extrusion block 21 abuts against the push rod 14. A push spring 22 is sleeved on the telescopic rod 20.

[0050] Before laying, workers can attach the ends of the carbon fiber cloth to the silicone nano-adhesive patch 16. When the laying frame 3 rises, the extrusion block 21 is squeezed by the top surface, which pushes the push rod 14 to lift the silicone nano-adhesive patch 16 on the adhesion plate 15, thereby bringing the carbon fiber cloth into contact with the frame beam surface and the pre-applied adhesive on the frame beam, completing the adhesion of the carbon fiber cloth ends and effectively preventing the ends from flipping up. Through the flexible adhesion characteristics of the adhesion plate 15 and the silicone nano-adhesive patch 16, combined with the mechanical linkage mechanism of the wedge-shaped extrusion block 21 and the push rod 14, the precise positioning and automatic adhesion of the carbon fiber cloth ends are achieved. The telescopic rod 3 20 is pressed and drives the wedge-shaped extrusion block 21 to move linearly, synchronously... Pushing the push rod 14 moves the silicone nano-adhesive patch 16, allowing the end of the carbon fiber cloth to make zero-gap contact with the pre-coated adhesive layer of the beam. The elastic energy storage characteristics of the return spring 18 automatically retract the push rod 14 after adhesion to release mechanical stress. The rigid guiding structure of the L-shaped plate 19 and the telescopic rod 20 ensures the positioning accuracy of the end, solving the interface defects such as end warping and discontinuous adhesive layer caused by manual pasting in traditional processes. This ensures the reliability of the fiber cloth end anchoring and the continuity of the overall reinforcement layer. At the same time, the design of the silicone nano-adhesive patch 16 ensures that it does not generate excessive adhesion force when it detaches from the carbon fiber cloth, thus not affecting the firmness of the carbon fiber cloth. Furthermore, the silicone nano-adhesive patch 16 can be recycled, saving costs.
