Description

TECHNICAL FIELD

[0001] The present application relates to a prestressed carbon fiber cloth layered single or multi-layer simultaneous tension anchoring system and method, belonging to the technical field of civil engineering bridge structure. BACKGROUND

[0002] Non-prestressed carbon fiber reinforced polymer (CFRP) reinforcement technology has been widely used in the reinforcement of reinforced concrete (RC) bridges, but engineering practice shows that this reinforcement technology cannot fully develop the high strength performance of CFRP materials, cannot effectively inhibit the cracking and development of bridge cracks, and brittle failure often occurs between the CFRP and the concrete interface. Therefore, prestressed CFRP technology is increasingly valued in bridge reinforcement. However, the current prestressed CFRP cloth tensioning and anchoring equipment and pasting process are complex and difficult to apply in actual engineering.

[0003] Therefore, it is urgent to develop a simple, convenient, layered tensioning and anchoring, and multi-layer simultaneous tensioning and anchoring prestressed tensioning and anchoring equipment to better improve and enhance the effect of bridge maintenance and reinforcement, aiming at the defects of non-prestressed CFRP reinforcement technology and the deficiencies of current prestressed CFRP reinforcement tensioning and anchoring equipment. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a prestressed carbon fiber cloth layered single or multi-layer simultaneous tension anchoring system and method. After the carbon fiber cloth is pre-tensioned, it is anchored on the reinforced member by using a mechanical anchoring method and a hybrid pasting technology that combines the external pasting method of directly pasting the carbon fiber cloth on the surface of the reinforced member through structural adhesive, fully develops the performance of the carbon fiber cloth, improves the work efficiency, and simplifies the construction steps.

[0005] The present application adopts the following technical solutions:

[0006] A prestressed carbon fiber cloth layered single or multi-layer simultaneous tension anchoring system, comprising a tensioning device and an anchoring steel plate, the tensioning device comprising a counterforce seat, a pressure sensor, a jack, a guide rail system and an end seat, the guide rail system comprising a fixed sliding guide rail and a sliding body located on the sliding guide rail and capable of sliding along the sliding guide rail, the counterforce seat being a rectangular thin plate, preferably fixed to the surface of the reinforced member by bolts through the inside reserved bolt holes, a square groove being provided in the middle of the upper surface of the counterforce seat, the inside being hollow for placing the pressure sensor, both being connected by bolts, at the same time, the square groove near the end seat is removed, so that the pressure sensor is connected with the jack, a longitudinal through groove is provided in the middle of the bottom surface of the counterforce seat, so that there is a gap between the counterforce seat and the reinforced member, so that the carbon fiber cloth can pass through, and the counterforce seat as a whole provides a counterforce for the thrust generated by the jack; at the same time, the counterforce seat is connected with one end of the sliding guide rail by bolts through the outside reserved bolt holes;

[0007] The pressure sensor is placed in the hollow inside the reaction seat, one end of which is connected to the reaction seat by bolts, and the other end is connected to the jack by bolts. The pressure sensor is externally connected to a pressure display instrument, which displays the jack thrust in real time to achieve the purpose of controlling the prestressing of the carbon fiber cloth;

[0008] The sliding guide rail is an I-shaped strip, with one rail provided on each side of the reaction seat. A bolt hole is provided at a fixed distance on the top of the sliding guide rail. One end of the sliding guide rail is connected to the bolt hole reserved on the outside of the reaction seat by bolts, and the other end of the sliding guide rail is connected to the bolt hole reserved on the outside of the end seat by bolts to form a stretcher structure.

[0009] The piston end of the jack is in close contact with the sliding body, and the other end is connected to the pressure sensor through a bolt. The jack provides thrust through the oil pump to push the sliding body to slide along the sliding guide rail;

[0010] The anchoring steel plate includes a proximal anchoring plate, a distal anchoring plate and a pressure plate. The proximal anchoring plate is used for the tensioning end, and is self-lockingly wound to connect one end of the carbon fiber cloth. At the same time, the proximal anchoring plate is fixedly connected to the sliding body by bolts; the distal anchoring plate is used for distal anchoring, and is anchored to the reinforced component after being connected to the other end of the carbon fiber cloth by self-locking winding before tensioning, thereby playing a fixing role; the pressure plate is mainly used to mark the position of the pressure plate according to the preset spacing after the tensioning is completed, drill holes on the surface of the reinforced component, and embed chemical bolts. When the cooling intensity of the agent is sufficient, the pressure plate is anchored to further fix the carbon fiber cloth.

[0011] Preferably, the distal anchoring plate is a rectangular parallelepiped steel plate, preferably a 45-gauge steel plate with a length of 16 cm, a width of 6 cm, and a height of 1.5 cm;

[0012] The distal anchoring plate is provided with a slit in the middle of the steel plate along the long side direction for the carbon fiber cloth to pass through for self-locking winding connection. The slit is preferably 10 cm long and 1 cm wide. Anchor holes are respectively left in the middle of both ends of the distal anchoring plate to facilitate anchoring and fixing with the reinforced component.

[0013] The width of the carbon fiber cloth is equal to the length of the slit in the middle of the distal anchor plate, and the carbon fiber cloth should be wrapped and connected to the middle of the distal anchor plate as much as possible to prevent the carbon fiber cloth from wrinkling during the entire tensioning and anchoring process, resulting in stress concentration and difficulty in bonding. In the tensioning process, the carbon fiber cloth is not wrapped and connected to the middle of the distal anchor plate, causing the distal anchor plate to be subjected to eccentric force, resulting in excessive force on the anchor bolts on one side of the distal anchor plate.

[0014] Preferably, the proximal anchoring plate is also a rectangular parallelepiped steel plate, preferably a 45-gauge steel plate with a length of 16 cm, a width of 6 cm, and a height of 1.5 cm;

[0015] The proximal anchor plate is provided with a slit in the middle of the steel plate along the long side direction. The slit is preferably 11 cm long and 1 cm wide, for the carbon fiber cloth to pass through for self-locking winding connection; anchor holes are left in the middle of both ends of the proximal anchor plate to facilitate anchoring and fixation with the reinforced component. At the same time, bolt holes are left on both sides of the anchor hole for connecting the proximal anchor plate with the Z-shaped clamp; the carbon fiber cloth should also be wrapped and connected to the middle of the proximal anchor plate as much as possible to prevent the proximal anchor plate from being subjected to eccentric force during the tensioning process, resulting in excessive force on the connecting bolts on one side of the proximal anchor plate and the Z-shaped clamp.

[0016] Preferably, the sliding body includes a sliding vehicle, an L-shaped bearing plate and an L-shaped fixing plate, wherein the L-shaped fixing plates are two and are respectively located on the sliding guide rails, and the L-shaped bearing plates are located at the ends of the two L-shaped fixing plates close to the reaction seat and are fixedly connected to the L-shaped fixing plates;

[0017] Two sliding cars are arranged on each side of the sliding guide rail, wherein the top of one sliding car is fixedly connected to the L-shaped fixing plate, and the other is fixedly connected to the L-shaped bearing plate. The interior of the sliding car is T-shaped and fits tightly with the upper half of the I-shaped sliding guide rail;

[0018] The two trolleys are spaced the length of the L-shaped fixing plate. Bolts are placed through pre-set bolt holes on the top of the trolleys to connect to the L-shaped fixing plate and L-shaped load-bearing plate. The connection method is as follows: For one L-shaped fixing plate, the end closest to the reaction seat is bolted through the pre-set bolt holes in the order of the L-shaped load-bearing plate, L-shaped fixing plate, and one trolley. For the end closest to the end seat, bolts are placed through the pre-set bolt holes in the order of the L-shaped fixing plate, and then the other trolley.

[0019] Each sliding guide rail is equipped with two sliding carriages that can slide freely along the guide rail; the length of the guide rail between the reaction seat and the end seat is the sliding distance, which can be adjusted by connecting the end seat with different bolt holes on the top of the guide rail;

[0020] Preferably, a whole row of steel balls are provided on the contact surfaces on both sides of the sliding carriage and the sliding guide rail to reduce the friction of the contact surfaces so that the L-shaped load-bearing plate can drive the sliding carriage to slide freely on the sliding guide rail under the loading of the jack.

[0021] Preferably, the L-shaped load-bearing plate has an L-shaped cross-section, wherein one side of the L-shaped load-bearing plate is parallel to the reinforcing member, and its two ends are connected to the two L-shaped fixing plates by bolts; the other side of the L-shaped load-bearing plate is perpendicular to the reinforcing member, and is in close contact with the end of the jack piston. At the same time, there is a gap between the L-shaped load-bearing plate and the reinforcing member to allow the carbon fiber cloth to pass through. Under the push of the jack piston, the L-shaped fixing plate and the sliding car are driven to slide forward along the sliding guide rail.

[0022] Preferably, the L-shaped fixing plate has an L-shaped cross-section, wherein one side of the L-shaped fixing plate is parallel to the reinforced component, and serves as a connecting component, with bolt holes preset at fixed distances for connecting and fixing the sliding vehicle, the L-shaped load-bearing plate, and the Z-shaped clamp. At the same time, one L-shaped fixing plate connects multiple Z-shaped clamps.

[0023] The L-shaped fixing plate is parallel to the side of the reinforced component, and one end near the reaction seat is connected to the L-shaped bearing plate and the sliding carriage by bolts. The end near the end seat of the L-shaped fixing plate is connected to another sliding carriage by bolts. Driven by the L-shaped bearing plate, it slides freely along the sliding guide rail together with the sliding carriage; the other side of the L-shaped fixing plate is perpendicular to the reinforced component, wrapping the sliding guide rail to protect the guide rail; an L-shaped fixing plate is set on each side of the sliding guide rail.

[0024] Preferably, the two L-shaped fixing plates are each provided with a Z-shaped clamp, and the Z-shaped clamps on the two L-shaped fixing plates are correspondingly arranged to form a pair for fixing the proximal anchoring plate;

[0025] The upper horizontal side of the Z-shaped clamp has a preset bolt hole, which is used to connect and fix the Z-shaped clamp to the L-shaped fixing plate on one side through bolts; the lower horizontal side of the Z-shaped clamp has a one-centimeter gap reserved between it and the reinforced component, and a preset bolt hole is also provided, which is used to connect and fix the lower horizontal side to one end of the proximal anchor plate through bolts;

[0026] The Z-shaped clamp and the L-shaped fixing plate are connected and fixed through different bolt holes to adjust the position of the proximal anchor plate, thereby avoiding the steel bars and facilitating the anchoring of the proximal anchor plate. At the same time, when the L-shaped fixing plate slides, the Z-shaped clamp drives the proximal anchor plate to slide along the sliding guide rail. By increasing or decreasing the number of Z-shaped clamps, the number of fixed proximal anchor plates can be controlled, that is, the number of carbon fiber cloth layers can be controlled, thereby achieving the requirement of simultaneous tensioning of multiple layers of carbon fiber cloth.

[0027] Preferably, the end seat is a rectangular thin plate with bolt holes reserved on both sides for connection with the sliding guide rail, and the reaction seat and the end seat are connected to the sliding guide rail in front and back to form a stretcher structure;

[0028] There are 4 bolt holes on the inner side of the end seat, which are connected to the reinforced components to provide support for the entire equipment, ensure that the equipment is tightly connected to the reinforced components, facilitate operation and ensure safety.

[0029] A method for simultaneously tensioning and anchoring prestressed carbon fiber cloth layers individually or in multiple layers, comprising the following steps:

[0030] (1) The anchoring system is disassembled into four parts in advance by loosening the bolts: reaction seat, jack, guide rail system (including sliding guide rail, L-shaped load-bearing plate, sliding car, L-shaped fixing plate, Z-shaped clamp), end seat, and the line is laid out at the set position on the surface of the reinforced component. The inner bolt hole of the end seat is drilled in advance on the proximal surface of the reinforced component, and the bolts are embedded. The distance between the end seat and the distal anchor plate is the length of the carbon fiber cloth. The length of the carbon fiber cloth can be adjusted by adjusting the position of the end seat and the distal anchor plate. When the end seat is located at the edge of one end of the reinforced component and the distal anchor plate is located at the edge of the other end of the reinforced component, the carbon fiber cloth on the surface of the reinforced component can be completely adhered and reinforced. After the reaction seat and the end seat are installed, one end of the sliding guide rail is connected and fixed to the bolt hole reserved on the outside of the reaction seat by bolts, and then the other end of the sliding guide rail is connected and fixed to the bolt hole reserved on the outside of the end seat by bolts to complete the system installation.

[0031] (2) Fix the Z-shaped clamps on the L-shaped fixing plate. The number of Z-shaped clamps depends on the number of carbon fiber cloth layers to be tensioned simultaneously. By adjusting the spacing between the Z-shaped clamps, the stirrups are prevented from being touched when drilling the proximal anchor plate.

[0032] Pass a single or multiple layers of carbon fiber cloth through the bottom of the tensioning device at the same time. The spatial relationship of the carbon fiber cloth is as follows: the first layer of carbon fiber cloth is in close contact with the surface of the reinforced component; the second layer of carbon fiber cloth is in close contact with the surface of the first layer of carbon fiber cloth; the third layer of carbon fiber cloth is in close contact with the surface of the second layer of carbon fiber cloth, and so on.

[0033] One end of each layer of carbon fiber cloth is connected to a proximal anchor plate by self-locking winding. The order of connecting the carbon fiber cloth and the proximal anchor plate is as follows: the proximal anchor plate connected to the first layer of carbon fiber cloth is connected to the Z-shaped clamp closest to the end seat by bolts; the proximal anchor plate connected to the second layer of carbon fiber cloth is connected to the Z-shaped clamp closest to the end seat by bolts, and so on. This can avoid the situation where the carbon fiber cloth covers other proximal anchor plates after anchoring due to the wrong sequence of proximal anchor plates, thereby causing stress concentration; during the tensioning process, the jack pushes the L-shaped fixing plate, which will drive multiple layers of carbon fiber cloth to be tensioned at the same time, and the tensioning length of each layer of carbon fiber cloth is the same. Anchoring is performed immediately after the tensioning is completed. The spacing between the Z-shaped clamps is the spacing after the proximal anchor plates are finally anchored. In the above order, one end of each layer of carbon fiber cloth is wrapped and connected with the correct proximal anchor plate and then fixed to the Z-shaped clamp;

[0034] Pre-drill holes at the designated distal anchorage locations for the subsequent distal anchor plate anchorage. Insert chemical bolts and wait for the chemical to cool and stabilize. Because the pre-drilled holes are the final distal anchor plate anchorage locations, the longitudinal spacing of the holes should be carefully controlled during drilling, avoiding the pre-measured stirrup locations while remaining greater than the width of a single distal anchor plate. The transverse spacing of the holes should be the same as the spacing between the two anchor holes in the distal anchor plate.

[0035] The other end of each layer of carbon fiber cloth is connected to a distal anchor plate using a self-locking winding method. The order of anchoring positions is as follows: the distal anchor plate connected to the first layer of carbon fiber cloth is closest to the end edge of the reinforced component; the distal anchor plate connected to the second layer of carbon fiber cloth is second closest to the end edge of the reinforced component, and so on. The distal anchor plate is brushed with impregnating glue all around to completely saturate the carbon fiber cloth, and then the distal anchor plate is anchored with pre-buried chemical bolts.

[0036] (3) Install the jack, connect the oil pump, apply the impregnation glue to the preset carbon fiber cloth pasting place on the surface of the reinforced component, apply the impregnation glue between each layer of carbon cloth, and immediately start pressing the oil pump after the impregnation glue is applied to make the jack generate thrust, push the L-shaped load-bearing plate to drive the mutually connected sliding car, L-shaped fixing plate, Z-shaped clamp, and proximal anchor plate to slide forward together, and the carbon fiber cloth is tensioned; immediately start tensioning after the impregnation glue is applied to avoid premature solidification of the impregnation glue and resulting in failure of pasting; stop pressurizing when the pressure display reaches the predetermined value; drill holes through the anchor holes reserved in the proximal anchor plate on the surface of the reinforced component and bury chemical bolts; after the agent cools and solidifies and the anchor rod is fixed, remove the connecting bolts of each proximal anchor plate and the Z-shaped clamp respectively, and then tighten the nuts to fix the proximal anchor plate to the surface of the reinforced component; relieve the pressure on the jack, and the anchor rod of the proximal anchor plate provides the reaction force instead of the jack;

[0037] (4) Remove the system in the order of jack, sliding guide, reaction seat, and end seat; after the equipment is disassembled and the impregnation glue applied between the surface of the reinforced component and the carbon fiber cloth layer is completely adhered and solidified, apply the impregnation glue again on the surface of the single or multi-layer carbon fiber cloth that has been adhered and anchored to ensure that the impregnation glue fully penetrates the multi-layer carbon fiber cloth so that the carbon fiber cloth and the base material are effectively bonded to form a unified whole and work together; at the same time, the impregnation glue solidified on the surface also has a good isolation and protection effect on the bottom carbon fiber cloth that is in direct contact with the air, thereby improving the durability of the carbon fiber cloth and thus enhancing the reinforcement effect; finally, use a scraper to scrape off the excess impregnation glue on the surface of the carbon fiber cloth to ensure that the impregnation glue is evenly applied;

[0038] (5) Starting from the anchoring steel plate at one end, mark the surface of the reinforced component with a marker pen at a preset distance (usually set to 3m, which can be adjusted according to the actual engineering reinforcement situation) along the reinforcement direction of the carbon fiber cloth. The marked position is the anchoring position of the pressure plate; preferably, the pressure plate is made of 45 steel, a rectangular steel plate with a length of 16 cm, a width of 6 cm, and a height of 1 cm, with anchor holes in the middle of both ends to facilitate anchoring and fixing with the reinforced component;

[0039] After the pressure plate is anchored, it should be symmetrical with the carbon fiber cloth along the same longitudinal center line, that is, the distance between the two anchor holes of the pressure plate and the longitudinal center line of the carbon fiber cloth is the same. The longitudinal positioning is marked with a marker, and the transverse positioning is the distance between the longitudinal center line of the carbon fiber cloth and the anchor hole of the pressure plate.

[0040] Drill holes and embed chemical bolts. After the agent cools and the anchor rod is completely stable, anchor the pressure plate. Apply marble glue evenly on the contact surface between the pressure plate and the carbon fiber cloth to ensure that the pressure plate and the carbon fiber cloth are bonded together while preventing the pressure plate from damaging the carbon fiber cloth. Tighten the pressure plate with the nut and clean up the excess marble glue. Paint the surface of the pressure plate to prevent rust caused by moisture and oxygen in the air.

[0041] Preferably, in step (2), the self-locking winding linking method of the carbon fiber cloth and the proximal anchor plate or the distal anchor plate is as follows: Figure 7 As shown in the figure, the anchor plate is divided into left and right sides with the narrow gap in the middle of the proximal anchor plate / distal anchor plate as the boundary. The end of the carbon fiber cloth first passes through the narrow gap and wraps around the right side of the anchor plate for two weeks. Then the carbon fiber cloth is pulled to completely tighten the two weeks of carbon fiber cloth wrapped around the right side of the anchor. The end of the carbon fiber cloth is compacted and fixed in it. Finally, the carbon fiber cloth led out of the narrow gap is wrapped around the left side of the anchor plate for several weeks and led out along one side of the anchor plate.

[0042] Where the present invention is not exhaustive, existing technologies may be used.

[0043] The beneficial effects of the present invention are:

[0044] (1) The carbon fiber cloth tensioning system of the present invention can independently select to tension the carbon fiber cloth in a single layer or in multiple layers simultaneously based on actual engineering requirements. If the reinforcement design is to reinforce a single layer of carbon fiber cloth, the carbon fiber cloth can be tensioned separately in each layer; if the reinforcement design is to reinforce multiple layers of carbon fiber cloth, the carbon fiber cloth can be tensioned in multiple layers simultaneously.

[0045] (2) The present invention can adjust the length of the carbon fiber cloth attached to the surface of the reinforced component by adjusting the position of the end seat and the distal anchor plate. When the end seat is located at one edge of the reinforced component and the distal anchor plate is located at the other edge of the reinforced component, the carbon fiber cloth can be completely attached and reinforced to the surface of the reinforced component.

[0046] (3) Prestressing: A jack applies thrust to the L-shaped bearing plate, causing the sliding carriage connected to the L-shaped bearing plate to drive the guide rail system to slide as a whole, thereby tensioning the carbon fiber cloth wrapped around the proximal anchor plate and generating prestress. To reduce the difference between the jack thrust and the actual applied prestress, a row of steel balls is installed inside the sliding carriage to contact the sliding guide rail, turning the original sliding friction into rolling friction, thereby reducing friction and making the application of prestress more accurate.

[0047] (4) Once the carbon fiber cloth is tensioned, the proximal anchor plate can be directly anchored without waiting for the impregnated glue to completely solidify. This greatly simplifies the construction steps and reduces the construction period. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0058] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, they will be described in detail below with reference to the accompanying drawings and specific embodiments, but are not limited thereto. Matters not fully described in the present invention shall be based on conventional techniques in the art.

[0059] Example 1:

[0060] A prestressed carbon fiber cloth layered single or multi-layer tensioning anchoring system, such as Figure 1-9 As shown, it includes a tensioning device and an anchoring steel plate. The tensioning device includes a reaction seat 1, a pressure sensor 2, a jack 3, a guide rail system and an end seat 9. The guide rail system includes a fixed sliding guide rail 4 and a sliding body located on the sliding guide rail 4 and capable of sliding along the sliding guide rail. The reaction seat 1 is a rectangular thin plate, preferably fixed to the surface of the reinforced component by bolts through the inner reserved bolt holes. A square groove is provided in the middle of the upper surface of the reaction seat 1, and the inner hollow is used to place the pressure sensor 2. The two are connected by bolts. At the same time, the square groove is removed near the end seat so that the pressure sensor is connected to the jack. A longitudinal through groove is provided in the middle of the bottom surface of the reaction seat 1 so that there is a gap between the reaction seat and the reinforced component to allow the carbon fiber cloth to pass through. The reaction seat 1 as a whole provides a reaction force for the thrust generated by the jack; at the same time, the reaction seat 1 is connected to one end of the sliding guide rail 4 by bolts through the outer reserved bolt holes;

[0061] The pressure sensor 2 is placed in the hollow inside the reaction seat 1. One end is connected to the reaction seat 1 with a bolt, and the other end is connected to the jack 3 with a bolt. The pressure sensor 2 is externally connected to a pressure display instrument, which displays the thrust of the jack 3 in real time to achieve the purpose of controlling the prestressing of the carbon fiber cloth.

[0062] The sliding guide rail 4 is an I-shaped strip, with one set on each side of the reaction seat 1. A bolt hole is set at a fixed distance on the top of the sliding guide rail 4. One end of the sliding guide rail 4 is connected to the bolt hole reserved on the outside of the reaction seat by bolts, and the other end of the sliding guide rail 4 is connected to the bolt hole reserved on the outside of the end seat 9 by bolts to form a stretcher structure.

[0063] The piston end of the jack 3 is in close contact with the sliding body, and the other end is connected to the pressure sensor 2 through a bolt. The oil pump increases pressure, and the jack 3 provides thrust to push the sliding body to slide along the sliding guide rail.

[0064] The anchoring steel plate includes a proximal anchoring plate 16, a distal anchoring plate 17 and a pressure plate 18. The proximal anchoring plate 16 is used for the tensioning end, and is self-lockingly wound to connect one end of the carbon fiber cloth. At the same time, the proximal anchoring plate 16 is fixedly connected to the sliding body by bolts; the distal anchoring plate 17 is used for distal anchoring. Before tensioning, it is connected to the other end of the carbon fiber cloth by self-locking winding and then anchored to the reinforced component to play a fixing role; the pressure plate 18 is mainly used to mark the position of the pressure plate according to the preset spacing after the tensioning is completed, drill holes on the surface of the reinforced component, and embed chemical bolts. When the cooling intensity of the agent is sufficient, the pressure plate is anchored to further fix the carbon fiber cloth.

[0065] Example 2:

[0067] The distal anchoring plate 17 is provided with a slit 22 in the middle of the steel plate along the longitudinal direction for the carbon fiber cloth to pass through for self-locking wrapping connection. The slit is preferably 10 cm long and 1 cm wide. Anchor holes 14 are respectively provided in the middle of both ends of the distal anchoring plate to facilitate anchoring and fixing to the reinforced component.

[0068] The width of the carbon fiber cloth is equal to the length of the slit in the middle of the distal anchor plate, and the carbon fiber cloth should be wrapped and connected to the middle of the distal anchor plate as much as possible to prevent the carbon fiber cloth from wrinkling during the entire tensioning and anchoring process, resulting in stress concentration and difficulty in bonding. In the tensioning process, the carbon fiber cloth is not wrapped and connected to the middle of the distal anchor plate, causing the distal anchor plate to be subjected to eccentric force, resulting in excessive force on the anchor bolts on one side of the distal anchor plate.

[0069] Example 3:

[0071] The proximal anchor plate 16 is provided with a slit 22 in the middle of the steel plate along the long side direction. The slit is preferably 11 cm long and 1 cm wide, for the carbon fiber cloth to pass through for self-locking winding connection; anchor holes 14 are respectively left in the middle of both ends of the proximal anchor plate 16 to facilitate anchoring and fixing with the reinforced component. At the same time, bolt holes 15 are left on both sides of the anchor holes for connecting the proximal anchor plate to the Z-shaped clamp 8; the carbon fiber cloth should also be wrapped and connected to the middle of the proximal anchor plate as much as possible to prevent the proximal anchor plate from being subjected to eccentric force during the tensioning process, resulting in excessive force on the connecting bolts on one side of the proximal anchor plate and the Z-shaped clamp.

[0072] Example 4:

[0073] A prestressed carbon fiber cloth layered single or multi-layer tensioning and anchoring system, as described in Example 3, except that the sliding body includes a sliding carriage 6, an L-shaped bearing plate 5 and an L-shaped fixing plate 7, two L-shaped fixing plates 7 are respectively located on the sliding guide rails 4, and the L-shaped bearing plates 5 are located at the ends of the two L-shaped fixing plates 7 near the reaction seats and are fixedly connected to the L-shaped fixing plates 7;

[0074] Two sliding trolleys 6 are provided on each side of the sliding guide rail, one of which is fixedly connected to the L-shaped fixing plate 7 on the top, and the other is fixedly connected to the L-shaped bearing plate 5. The interior of the sliding trolley 6 is T-shaped and fits tightly with the upper half of the I-shaped sliding guide rail;

[0075] The two trolleys are spaced the length of the L-shaped fixing plate. Bolts are placed through pre-set bolt holes on the top of the trolleys to connect them to the L-shaped fixing plate 7 and the L-shaped support plate 5. The connection method is as follows: On one side of the L-shaped fixing plate, the end closest to the reaction seat is bolted through the pre-set bolt holes in the order of the L-shaped support plate, the L-shaped fixing plate, and the trolley. On the other side, the end closest to the end seat is bolted through the pre-set bolt holes in the order of the L-shaped fixing plate, the other trolley, and the other trolley.

[0076] Each sliding guide rail is equipped with two sliding carriages that can slide freely along the guide rail; the length of the guide rail between the reaction seat and the end seat is the sliding distance, which can be adjusted by connecting the end seat with different bolt holes on the top of the guide rail;

[0077] Preferably, a whole row of steel balls are provided on the contact surfaces on both sides of the sliding carriage and the sliding guide rail to reduce the friction of the contact surfaces so that the L-shaped load-bearing plate can drive the sliding carriage to slide freely on the sliding guide rail under the loading of the jack.

At the same time, there is a gap between the L-shaped bearing plate 5 and the reinforcement member to allow the carbon fiber cloth to pass through. Under the push of the jack piston, the L-shaped fixing plate and the sliding vehicle are driven to slide forward along the sliding guide rail.

[0080] Example 6:

[0081] A prestressed carbon fiber cloth layered single or multi-layer tensioning and anchoring system, as described in Example 5, except that the L-shaped fixing plate 7 has an L-shaped cross-section, wherein one side of the L-shaped fixing plate 7 is parallel to the reinforced member, and serves as a connecting member, and bolt holes are preset at fixed intervals for connecting and fixing the sliding vehicle 6, the L-shaped bearing plate 5, and the Z-shaped clamp 8, and a single L-shaped fixing plate connects multiple Z-shaped clamps;

[0082] The L-shaped fixing plate 7 is parallel to the side of the reinforced component, and one end near the reaction seat is connected to the L-shaped bearing plate 5 and the sliding carriage 6 by bolts. The end near the end seat of the L-shaped fixing plate 7 is connected to another sliding carriage by bolts.

[0083] Example 7:

[0085] The upper horizontal side of the Z-shaped clamp 8 is provided with a bolt hole, and the Z-shaped clamp 8 is connected and fixed to the L-shaped fixing plate 7 on one side by bolts; the lower horizontal side of the Z-shaped clamp 8 is provided with a one-centimeter gap between it and the reinforced component, and a bolt hole is also provided, and the lower horizontal side is connected and fixed to one end of the proximal anchor plate by bolts;

[0086] The Z-shaped clamp 8 is connected and fixed to the L-shaped fixing plate 7 through different bolt holes to achieve position adjustment of the proximal anchor plate, thereby avoiding the steel bars and facilitating the anchoring of the proximal anchor plate; at the same time, when the L-shaped fixing plate slides, the Z-shaped clamp drives the proximal anchor plate to slide along the sliding guide rail; by increasing or decreasing the number of Z-shaped clamps, the number of fixed proximal anchor plates can be controlled, that is, the number of carbon fiber cloth layers 10 can be controlled, so as to achieve the requirement of simultaneous tensioning of multiple layers of carbon fiber cloth.

[0087] like Figure 4 As shown, the Z-shaped clamp 8 is fixed to the proximal anchor plate A11, proximal anchor plate B12, and proximal anchor plate C13 by bolts, and is also connected to the L-shaped fixing plate 7 by bolts. The L-shaped fixing plate 7 is connected to the sliding car 6 by bolts in front and back so that it can slide freely on the sliding guide rail 4 with the sliding car 6.

The number of Z-shaped clamps 8 can be set in pairs according to the number of carbon fiber cloth reinforcement layers, and fixed to the L-shaped fixing plate 7 at the same time to tension multiple layers of carbon fiber cloth, such as Figure 5 As shown, there are three pairs of Z-type clamps used to reinforce three layers of carbon fiber cloth.

[0088] Example 8:

[0090] Four bolt holes are provided on the inner side of the end seat 9, which are connected to the reinforced component to provide support for the entire equipment, ensure that the equipment is tightly connected to the reinforced component, facilitate operation, and ensure safety.

[0091] Example 9:

[0092] Taking the tensioning reinforcement of three layers of prestressed carbon fiber cloth as an example, the method of tensioning and anchoring prestressed carbon fiber cloth layers individually or multiple layers simultaneously includes the following steps:

[0093] (1) Grind, remove dust, and apply primer to the surface of the reinforced component. When the primer reaches a non-sticky state, use leveling materials to level the surface of the reinforced component;

[0094] After the leveling material is no longer sticky to the fingers, lay out the line at the set position on the surface of the reinforced component. The distance between the end seat and the distal anchor plate is the length of the carbon fiber cloth. The length of the carbon fiber cloth can be adjusted by adjusting the position of the end seat and the distal anchor plate. According to the end seat position set in advance by the length of the carbon fiber cloth, pre-drill the inner bolt holes of the end seat and the inner bolt holes of the reaction seat on the near-end surface of the reinforced component and embed the bolts. Figure 4 As shown, after installing the reaction seat and end seat, connect and fix the guide rail system. Use bolts to connect and fix one end of the sliding guide rail to the reserved bolt hole on the outside of the reaction seat. Then use bolts to connect and fix the other end of the sliding guide rail to the reserved bolt hole on the outside of the end seat. After the guide rail system is connected and fixed, the system installation is complete.

[0095] (2) Figure 5 As shown, a Z-shaped clamp 8 is used to secure the proximal anchor plate, which is then fastened to the L-shaped fixing plate 7 by tightening screws. Multiple layers of carbon fiber cloth are simultaneously threaded through the bottom of the tensioning device, with each layer of carbon fiber cloth connected to a proximal anchor plate using self-locking wrapping. The proximal anchor plate A 11, connected to the first layer of carbon fiber cloth, is bolted to the Z-shaped clamp closest to the end seat; the proximal anchor plate B 12, connected to the second layer of carbon fiber cloth, is bolted to the Z-shaped clamp more centrally located from the end seat; and the proximal anchor plate C 13, connected to the third layer of carbon fiber cloth, is bolted to the Z-shaped clamp farthest from the end seat. The proximal and distal anchor plates are connected using self-locking wrapping, avoiding pre-measured stirrup positions. The anchor positions are arranged in the following order: distal anchor plate 19, connected to the first layer of carbon fiber cloth, is closest to the end edge of the reinforced component; distal anchor plate 20, connected to the second layer of carbon fiber cloth, is more centrally located from the end edge of the reinforced component; and distal anchor plate 21, connected to the third layer of carbon fiber cloth, is farthest from the end edge of the reinforced component. Drill holes for the distal anchor plate at the preset position of the distal anchor, embed the chemical bolts, and after the agent cools and stabilizes, apply impregnation glue all around the distal anchor plate, allowing the impregnation glue to completely soak into the carbon fiber cloth, and then anchor the distal anchor plate;

[0096] (3) The jack 3 is fixed to the pressure sensor 2 by bolts, and the jack is connected to the oil pump. Apply impregnation glue to the surface of the reinforced component where the carbon fiber cloth is pre-pasted and between the layers of carbon fiber cloth. After applying the impregnation glue, start pressing the oil pump immediately to prevent the impregnation glue from solidifying prematurely and causing the adhesion to fail. As the proximal end presses the oil pump, the jack generates thrust, pushing the L-shaped load-bearing plate to drive the mutually connected sliding car, L-shaped fixing plate, Z-shaped clamp, and proximal anchor plate to slide forward together. The carbon fiber cloth connected to the anchor plate by self-locking changes from a relaxed state to a taut state, and the pressure display shows the force value. Continue to pressurize, and stop pressurizing when the force value reaches the predetermined pressure value. Drill holes 14 reserved through the anchor plate and bury chemical bolts. After the agent cools and solidifies and the anchor rod is fixed, remove the bolts connecting each Z-shaped clamp to the proximal anchor plate bolt hole 15, and then tighten the nuts to fix the anchor plate to the surface of the reinforced component. Unload the jack, and the anchor rod will replace the jack to provide reaction force;

[0097] (4) Dismantle the system in the order of jack, guide rail system, reaction seat, and end seat. After the system is dismantled and the impregnation glue applied between the surface of the reinforced component and the carbon fiber cloth layer is completely adhered and solidified, apply the impregnation glue again on the surface of the multi-layer carbon fiber cloth that has been adhered and anchored to ensure that the impregnation glue fully penetrates the multi-layer carbon fiber cloth. Use a scraper to scrape off the excess impregnation glue on the surface of the carbon fiber cloth to ensure that the impregnation glue is evenly applied;

[0098] (5) Starting from the proximal anchor plate connected to the first layer of carbon fiber cloth, mark the surface of the reinforced component with a marker pen every 3m according to the preset spacing, and embed chemical bolts. After the anchor rod is completely stable, install the pressure plate. Apply marble glue evenly on the contact surface between the pressure plate and the carbon fiber cloth to ensure that the pressure plate and the carbon fiber cloth are bonded while preventing the pressure plate from damaging the carbon fiber cloth. Tighten the pressure plate with the nut and clean the excess marble glue. Paint the surface of the pressure plate to prevent rust caused by moisture and oxygen in the air.

[0099] Example 10:

[0100] A method for simultaneously tensioning and anchoring prestressed carbon fiber cloth layers individually or in multiple layers is as described in Example 9, except that, in step (2), the self-locking winding linking method of the carbon fiber cloth and the proximal anchor plate or the distal anchor plate is as follows: Figure 7 As shown in the figure, the anchor plate is divided into left and right sides with the narrow gap in the middle of the proximal anchor plate / distal anchor plate as the boundary. The end of the carbon fiber cloth first passes through the narrow gap and wraps around the right side of the anchor plate for two weeks. Then the carbon fiber cloth is pulled to completely tighten the two weeks of carbon fiber cloth wrapped around the right side of the anchor. The end of the carbon fiber cloth is compacted and fixed in it. Finally, the carbon fiber cloth led out of the narrow gap is wrapped around the left side of the anchor plate for several weeks and led out along one side of the anchor plate.

[0101] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
