Description

Technical Field

[0001] This utility model relates to the field of concrete reinforcement technology, specifically to a detachable anchor for building construction. Background Technology

[0002] Prestressed carbon fiber composite plate reinforcement is an active reinforcement technology that applies initial prestress to concrete structures using prestressed carbon fiber plates, thereby increasing load-bearing capacity and delaying crack propagation. Before installing the carbon fiber plates, specialized tensioning equipment is used to apply prestress, placing them in a pre-tensioned state. This step is achieved through mechanical anchors, creating a reverse load effect on the structure. Throughout the reinforcement process, the tensioning equipment must remain operational to maintain the prestress; however, prolonged operation of such equipment significantly reduces its lifespan. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a detachable anchor for construction. This anchor consists of a threaded rod and a nut column as fasteners. After prestress is applied by the tensioning equipment, rotating the nut column will cause the fasteners to abut against the top plate and the cover plate, thus allowing the tensioning equipment to be disassembled. This avoids the tensioning equipment being in a working state for a long time, which would reduce its lifespan.

[0004] To achieve the above objectives, this utility model provides a detachable anchor for construction, comprising: A fixed-end clamp is provided on the bottom surface of a concrete structure. The fixed-end clamp includes a top plate and a first anchor bolt for fixing the top plate to the bottom surface of the concrete structure. A first groove for receiving a carbon fiber plate is provided at the bottom of the top plate. The tensioning end clamp is set at one end of the bottom surface of the concrete structure. The tensioning end clamp includes a cover plate and a bottom plate at the bottom of the cover plate. The cover plate is connected to the top of the bottom plate by a first bolt. The bottom plate has a convex cross section. The bottom of the cover plate has an inclined second groove, and the top of the bottom plate has an inclined third groove. The second groove and the third groove are opposite to each other and form a through hole with a rectangular cross section. The inverted L-shaped chute has two inverted L-shaped chutes. The two inverted L-shaped chutes are fixed to the bottom surface of the concrete structure by the second anchor bolts and are symmetrically installed on the two protruding sides of the bottom plate, so that the tensioning end clamp can move along the tensioning direction at one end of the bottom surface of the concrete structure. Fasteners, of which there are several, are disposed between the top plate and the cover plate so that the carbon fiber plate remains under tension after the tensioning equipment is disassembled; A fixed-end anchor plate is fixed to the bottom surface of the concrete structure away from the tensioning end clamp by a second bolt, and the fixed end of the carbon fiber plate is held in the fixed-end anchor plate. The tensioning end anchor plate is fixed to the bottom surface of the concrete structure by a third bolt on the side of the fixed end clamp away from the tensioning end clamp. The tensioning end of the carbon fiber plate passes through the fixed end clamp and is held in the tensioning end clamp, and is fixed to the bottom of the tensioning end anchor plate after tensioning is completed.

[0005] As a further improvement to this technical solution, both the top plate and the cover plate are L-shaped, and the long plates of the top plate and the cover plate are connected to the short plates by triangular plates, and the top plate and the cover plate are arranged back to back.

[0006] As a further improvement to this technical solution, the fastener includes a threaded rod and a nut post. The nut post is located on the side of the top plate opposite to the cover plate, and the threaded rod is located on the side of the cover plate opposite to the top plate. The end of the threaded rod away from the cover plate is threaded into the nut post.

[0007] As a further improvement to this technical solution, the first anchor bolt has several parts and is symmetrically arranged on the long side of the top plate. The long side of the top plate has a first through hole that matches the long thread of the first anchor bolt. The top surface of the top plate has a first groove that matches the nut of the first anchor bolt. After the long thread of the first anchor bolt passes through the first through hole and enters the concrete structure, it tightens its nut in the first groove so that the top plate is anchored to the bottom surface of the concrete structure.

[0008] As a further improvement to this technical solution, the through hole is inclined, and the first through hole on the side of the tensioning end clamp away from the fixed end clamp is higher than the second through hole on the side of the tensioning end clamp closer to the fixed end clamp.

[0009] As a further improvement to this technical solution, there are several second anchor bolts located in the inverted L-shaped groove, which are evenly distributed at the top of the inverted L-shaped groove along the direction of the carbon fiber plate. The inverted L-shaped groove has a second through hole that matches the long thread of the second anchor bolt, and a second groove that matches the nut of the second anchor bolt is opened on the top surface of the inverted L-shaped groove. After the long thread of the second anchor bolt passes through the second through hole and enters the concrete structure, it tightens its nut in the second groove, so that the inverted L-shaped groove is anchored to the bottom surface of the concrete structure.

[0010] As a further improvement to this technical solution, both the fixed end anchor plate and the tensioning end anchor plate have anchor plate conical holes on their bottom surfaces, and wedge-shaped clips are provided inside the anchor plate conical holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model uses the cooperation of tensioning end clamp and fixed end clamp to fix the anchor to the concrete structure with anchor bolts, and applies prestress to the carbon fiber plate through tensioning equipment. When the structure is subjected to external load, the pre-compression stress of the carbon fiber plate can offset part of the tensile stress, thereby improving the load-bearing capacity of the structure. Moreover, through the matching of fasteners composed of threaded rod and nut column, after the tensioning equipment applies prestress, the nut column is rotated to make the fastener abut against the top plate and the cover plate, so that the carbon fiber plate between the top plate and the cover plate is still in a tensile state, thereby avoiding the tensioning equipment from being in working state for a long time and reducing its service life.

[0012] (2) The present invention is fixed on the bottom surface of the concrete structure by means of an inverted L-shaped sliding groove. Two inverted L-shaped sliding grooves are symmetrically installed on the two protruding sides of the bottom plate, so that the tensioning end clamp can slide on the bottom surface of the concrete structure to facilitate the installation of the tensioning end clamp, and at the same time, the distance between the fixed end clamp and the tensioning end clamp can be adjusted.

[0013] (3) This utility model achieves the fixation of carbon fiber plate by the friction between the wedge-shaped clamp and the cone hole of the anchor plate. When the wedge-shaped clamp is pushed into the cone hole of the anchor plate, it will generate lateral pressure and friction, which will tightly clamp the carbon fiber plate. As the tensioning equipment tensions, the pressure between the inner wall of the cone hole of the anchor plate and the bottom surface of the wedge-shaped clamp increases, forming a continuous frictional resistance to prevent the carbon fiber plate from shrinking back.

[0027] like Figures 1-6 As shown, this utility model embodiment provides a detachable anchor for construction, including a fixed end clamp 1, a tensioning end clamp 22, an inverted L-shaped groove 3, a fastener 4, a fixed end anchor plate 5, and a tensioning end anchor plate 6. The fixed end clamp 1 is disposed on the bottom surface of the concrete structure and includes a top plate 101 and a first anchor bolt 102 that fixes the top plate 101 to the bottom surface of the concrete structure. The bottom of the top plate 101 has a first groove 103 for accommodating a carbon fiber plate 7. The tensioning end clamp 2 is disposed at one end of the bottom surface of the concrete structure and includes a cover plate 201 and a bottom plate 202 disposed at the bottom of the cover plate 201. The cover plate 201 is connected to the top of the bottom plate 202 by a first bolt 203. The bottom plate 202 has a convex cross-section. The bottom of the cover plate 201 has an inclined second groove 2011, and the top of the bottom plate 202 has an inclined third groove 2021. The second groove 2011 and the third groove 2021 are directly opposite each other. A rectangular through hole 204 is formed; two inverted L-shaped grooves 3 are provided, and the two inverted L-shaped grooves 3 are fixed to the bottom surface of the concrete structure by the second anchor bolts 301 and are respectively symmetrically installed on the two protruding sides of the bottom plate 202 so that the tensioning end clamp 2 can move along the tensioning direction at one end of the bottom surface of the concrete structure; several fasteners 4 are provided between the top plate 101 and the cover plate 201 so that the carbon fiber plate 7 is still in tension after the tensioning equipment is disassembled; the fixed end anchor plate 5 is fixed to the other end of the bottom surface of the concrete structure away from the tensioning end clamp 2 by the second bolt 501, and the fixed end of the carbon fiber plate 7 is held in the fixed end anchor plate 5; the tensioning end anchor plate 6 is fixed to the bottom surface of the concrete structure on the side of the fixed end clamp 1 away from the tensioning end clamp 2 by the third bolt 601, and the tensioning end of the carbon fiber plate 7 passes through the fixed end clamp 1 and is held in the tensioning end clamp 2, and is fixed to the bottom of the tensioning end anchor plate 6 after tensioning is completed.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, both the top plate 101 and the cover plate 201 are L-shaped. The long plates of the top plate 101 and the cover plate 201 are connected to the short plates by triangular plates, and the top plate 101 and the cover plate 201 are arranged back to back.

[0029] Specifically, the triangular plate is set to strengthen the integrated setting of the long plate and short side of the L-shaped top plate 101 or cover plate 201; the top plate 101 and cover plate 201 are set back to back to facilitate the setting of fasteners 4 between the two short sides.

[0030] In this embodiment, as Figure 1 As shown, the fastener 4 includes a threaded rod 401 and a nut post 402. The end of the threaded rod 401 away from the nut post 402 abuts against the side of the short plate of the cover plate 201 relative to the top plate 101. The nut post 402 is threadedly connected to the threaded rod 401, and the end of the nut post 402 away from the threaded rod 401 abuts against the side of the short plate of the top plate 101 relative to the cover plate 201.

[0031] Specifically, the length of the fastener 4 is adjusted by rotating the nut column 402, thereby adjusting the distance between the fixed end clamp 1 and the tensioning end clamp 2.

[0032] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, there are six first anchor bolts 102, which are symmetrically arranged on the long side of the top plate 101. The long side of the top plate 101 has a first through hole that matches the long thread of the first anchor bolt 102. The top surface of the top plate 101 has a first groove that matches the nut of the first anchor bolt 102. After the long thread of the first anchor bolt 102 passes through the first through hole and enters the concrete structure, it tightens its nut in the first groove, thereby anchoring the top plate 101 to the bottom surface of the concrete structure.

[0033] Specifically, when the top plate 101 is installed on the bottom surface of the concrete structure, holes are pre-drilled at the corresponding positions on the bottom surface of the concrete structure. The long thread of the first anchor bolt 102 is inserted into the drilled hole after passing through the first through hole, and then gently tapped with a hammer to ensure that it is fully inserted, ensuring that the first anchor bolt 102 fits tightly against the drilled hole wall. Finally, a wrench or wrench socket is used to install the nut in the first groove until it is tightened to the appropriate torque.

[0034] In this embodiment, as Figures 2-5 As shown, the through hole 204 is inclined, and the first opening 205 of the through hole 204 on the side of the tensioning end clamp 2 away from the fixed end clamp 1 is higher than the second opening 206 of the through hole 204 on the side of the tensioning end clamp 2 close to the fixed end clamp 1.

[0035] Specifically, the carbon fiber plate 7 enters the tensioning end clamp 2 from the first port 205 and exits through the inclined downward through hole 204 to the second port 206, so as to enter the first chute 103.

[0036] In this embodiment, as Figure 1 and Figure 2As shown, there are three second anchor bolts 301 located in the inverted L-shaped groove 3, which are evenly distributed at the top of the inverted L-shaped groove 3 along the direction of the carbon fiber plate 7. The inverted L-shaped groove 3 has a second through hole that matches the long screw of the second anchor bolt 301. The top surface of the inverted L-shaped groove 3 has a second groove that matches the nut of the second anchor bolt 301. After the long screw of the second anchor bolt 301 passes through the second through hole and enters the concrete structure, it tightens its nut in the second groove, so that the inverted L-shaped groove 3 is anchored to the bottom surface of the concrete structure. This allows the protruding sides of the bottom plate 202 to slide in the inverted L-shaped groove 3, thereby installing the tensioning end clamp 2 between the two inverted L-shaped grooves 3 and moving the tensioning end clamp to the designated position on the bottom surface of the concrete structure.

[0037] Specifically, when the inverted L-shaped groove 3 is installed on the bottom surface of the concrete structure, a hole is pre-drilled at the corresponding position on the bottom surface of the concrete structure. The long thread of the second anchor bolt 301 is inserted into the drilled hole after passing through the second through hole, and then gently tapped with a hammer to ensure that it is fully inserted, ensuring that the second anchor bolt 301 fits tightly against the drilled hole wall. Finally, a wrench or wrench socket is used to install the nut in the second groove until it is tightened to the appropriate torque.

[0038] In this embodiment, as Figure 2 and Figure 3 As shown, both the fixed end anchor plate 5 and the tensioning end anchor plate 6 have anchor plate conical holes 8 on their bottom surfaces, and wedge-shaped clips are provided inside the anchor plate conical holes 8.

[0039] Specifically, the carbon fiber plate 7 is fixed by the friction between the wedge-shaped clamp and the cone hole 8 of the anchor plate. When the wedge-shaped clamp is pushed into the cone hole 8 of the anchor plate, it generates lateral pressure and friction, which tightly clamps the carbon fiber plate 7. As the tensioning equipment tensions the carbon fiber plate 7, the pressure between the inner wall of the cone hole 8 of the anchor plate and the bottom surface of the wedge-shaped clamp increases, forming a continuous frictional resistance to prevent the carbon fiber plate 7 from shrinking back.

[0040] The working principle of this embodiment is as follows: When installing the anchor, the fixed end clamp 1 is first installed at a preset position on the bottom surface of the concrete structure using the first anchor bolt 102. Then, according to the installation requirements, the two symmetrically arranged inverted L-shaped grooves 3 are installed at preset positions on the bottom surface of the concrete structure opposite to the fixed end clamp 1 using the second anchor bolt 301. The protruding side surfaces on both sides of the bottom plate 202 of the tensioning end clamp 2 slide along the inverted L-shaped grooves 3 to the position relative to the preset bottom surface of the concrete structure. Then, the inverted L-shaped grooves 3 and the bottom plate 202 are reinforced together on the bottom surface of the concrete structure using the second anchor bolt. Then, the carbon fiber plate 7 is inserted into the tensioning end clamp 2 from the higher opening and exits through the inclined downward through hole 204 to the lower opening. The carbon fiber plate 7 then enters the first groove 103 of the fixed end clamp 1, and then successively enters the anchor plate conical hole 8 of the fixed end anchor plate 5 and the tensioning end anchor plate 6. Inside, the connection between the cover plate 201 and the bottom plate 202, as well as their connection to the bottom surface of the concrete structure, is reinforced by the first bolt 203. The connection between the top plate 101 and the bottom surface of the concrete structure is reinforced by the first anchor bolt 102. The connection between the fixed end anchor plate 5 and the bottom surface of the concrete structure is reinforced by the second bolt 501. The connection between the tensioning end anchor plate 6 and the bottom surface of the concrete structure is reinforced by the third bolt 601. This fixes the carbon fiber plate 7 within the through hole 204, the first groove 103, and the anchor plate conical holes 8 of the fixed end anchor plate 5 and the tensioning end anchor plate 6. Then, a jack 9 is vertically installed on the side of the top plate 101 facing the cover plate 201. The piston rod of the jack 9 moves toward the cover plate 201 and perpendicularly abuts against its surface, causing the tensioning end clamp 2 to move on the bottom surface of the concrete structure. This allows the jack 9 to apply prestress to the carbon fiber plate 7, placing the carbon fiber plate 7 in a tensile state (e.g., Figure 7 As shown), fastener 4 is then installed on the side of the short plate of the cover plate 201 facing the top plate 101, so that one end of the threaded rod 401 abuts against the side of the short plate of the cover plate 201 facing the top plate 101. The nut column 402 is rotated so that one end of the nut column 402 abuts against the side of the short plate of the top plate 101 facing the cover plate 201, thereby installing fastener 4 between the cover plate 201 and the top plate 101. This allows the carbon fiber plate 7 between the tensioning end clamp 2 and the fixed end clamp 1 to be in a tensile state without the jack 9, so that the jack 9 can be removed.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
