Description

Technical Field

[0001] This utility model relates to the field of building structure reinforcement technology, and in particular to a three-way sleeve grouting connector. Background Technology

[0002] In the field of building reinforcement, stone masonry load-bearing walls generally suffer from poor integrity and weak seismic performance due to limitations in material properties, structural composition, and masonry methods. This is especially true for the numerous stone masonry houses in coastal villages and towns of Fujian Province, where aging has exacerbated this problem, making seismic reinforcement a key focus of current construction work.

[0003] In existing technologies, the T-shaped pin-key reinforcement method is a commonly used method for reinforcing masonry load-bearing walls. This method involves cutting angle steel into L-shaped pins, welding two L-shaped pins together to form a T-shaped pin, embedding these pins into the intersecting horizontal and vertical joints of the masonry wall, then placing reinforcing bars at the horizontal joints, tightening the bars, and welding both ends to the pins. Finally, the joints are filled with mortar. However, this method has significant drawbacks: when the reinforcing bars are located inside the masonry wall, welding the ends of the bars to the pins is extremely inconvenient, resulting in low reinforcement efficiency; furthermore, the connection between the pins and the reinforcing bars relies solely on welding, which is prone to weld breakage under external forces such as earthquakes, affecting the stability of the reinforcement.

[0004] To address the aforementioned issues, three-way sleeve grouting connectors have emerged on the market, replacing traditional pins for connecting and fixing reinforcing ribs without the need for welding, thus improving construction efficiency. However, existing three-way sleeve grouting connectors still have shortcomings: First, the fixed angle of the sleeve body cannot adapt to the irregular joint angles in masonry load-bearing walls, limiting its applicability; second, epoxy resin backflow is prone to occur during grouting, resulting in incomplete grouting and affecting the connection strength between the reinforcing rib and the sleeve body; third, the fit between the clamping parts and the reinforcing rib is insufficient, and the lack of a buffer structure allows the reinforcing rib to easily slide relative to the clamping parts when the wall is under stress and deformed, reducing the reinforcement effect. Therefore, it is urgent to optimize the structure of existing three-way sleeve grouting connectors to improve their adaptability, stability, and reliability. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this utility model provides a three-way sleeve grouting connector, which solves the problems of low reinforcement efficiency of the T-pin tie-in method and the limitation of use caused by the fixed angle of the sleeve body in the three-way sleeve grouting connector.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: A three-way sleeve grouting connector is provided, comprising a grouting body having a hollow, closed structure, a grouting port with a cap, and multiple hinged connectors. The multiple hinged connectors are respectively arranged along the X, Y, and Z axes. Each hinged connector is hinged to a sleeve body, and each hinged connector and its sleeve body are in communication with the grouting body. Each sleeve body has a clamping member at its free end for clamping a reinforcing rib, and the end portion of the reinforcing rib is located inside the sleeve body.

[0007] Furthermore, each of the hinged connectors includes a hollow connecting rod, one end of which communicates with the interior of the grouting body, and the other end is provided with a connecting ball head, the connecting ball head having a through hole communicating with the interior of the hollow connecting rod; each of the sleeve bodies has a ball hinge connector base at its fixed end, the ball hinge connector base being hinged to the connecting ball head; the ball hinge connector base has a grouting channel communicating with the interior of the sleeve body.

[0008] Furthermore, a locking element is provided on the side of the ball joint connector base near the connecting ball head. The locking element includes a locking plate and a locking cylinder. A circular hole is provided through the middle of the locking plate. The diameter of the circular hole is larger than the diameter of the hollow connecting rod and smaller than the diameter of the connecting ball head. One end of the locking cylinder is fixedly provided on the end face of the locking plate. The circular hole is located inside the locking cylinder, and the outer wall of the locking cylinder is provided with external threads. The ball joint connector base has a threaded hole along its length on its end face. The locking cylinder is threadedly connected to the ball joint connector base through the external thread and the threaded hole. When the locking plate is turned, the locking cylinder engages with the threaded hole, causing the locking plate to move toward the connecting ball head until the round hole in the locking plate comes into tight contact with the outer contour surface of the connecting ball head, thus fixing the angle of the hinge connector and the sleeve body connected to it.

[0009] Furthermore, each of the sleeve bodies is provided with an exhaust port communicating with its interior, and the exhaust port is positioned close to the clamping member.

[0010] Furthermore, each of the sleeve bodies has multiple circumferentially spaced guide grooves inside, and each guide groove is arranged along the length direction of the sleeve body.

[0011] Furthermore, the clamping member includes two clamping pieces disposed at the free end of the sleeve body, with a gap between the two clamping pieces. When the two clamping pieces are combined, they form an outer contour of a frustum shape. The bottom of the two clamping pieces is fixedly connected to the free end of the sleeve body. The interior of the two clamping pieces is a cylindrical hollow structure. The diameter of the hollow interior of the two clamping pieces is larger than the diameter of the reinforcing rib. The reinforcing rib is disposed inside the hollow interior of the two clamping pieces. Two mounting ears are symmetrically disposed on both sides of the outer wall of each clamping piece, and the positions of the mounting ears of the two clamping pieces match.

[0012] Furthermore, an elastic buffer layer is provided on the inner wall of both clips, and the inner surface of the elastic buffer layer is provided with anti-slip texture.

[0013] Furthermore, the outer surfaces of the grouting body, hinged connectors, and clamping components are all coated with an anti-corrosion coating.

[0014] The beneficial effects of this utility model are as follows: 1. The three-way sleeve grouting connector of this utility model, by setting multiple hinged connectors for connecting the sleeve body in the grouting body, realizes the angle adjustment of the sleeve body and the reinforcing rib connected to the sleeve body. It can adapt to irregular masonry joints of different angles in stone masonry load-bearing walls, break the limitations of the traditional fixed angle sleeve body, expand the applicable scenarios of the connector, and make angle adjustment and grouting control convenient, simplifying construction steps, shortening the construction cycle, and significantly improving the reinforcement efficiency of stone masonry load-bearing walls.

[0015] 2. The three-way sleeve grouting connector of this utility model injects epoxy resin into the grouting body through a grouting port with a cap. The epoxy resin enters the sleeve body through the grouting body and the hinged connector, thereby fixing the reinforcing ribs. In actual use, multiple three-way sleeve grouting connectors and multiple reinforcing ribs are attached to the stone masonry load-bearing wall to form a reinforcing rib skeleton, improving the integrity of the wall, effectively restraining the wall from collapsing under earthquakes, and effectively improving the seismic bearing capacity of the wall.

[0016] 3. The three-way sleeve grouting connector in this utility model makes the grouting process of the sleeve body smoother by setting an exhaust port on the sleeve body and setting multiple guide grooves inside the sleeve body. The multiple guide grooves guide the epoxy resin to be evenly distributed, which strengthens the fixing effect on the reinforcing rib.

[0017] 4. The three-way sleeve grouting connector in this utility model can initially clamp and fix the reinforcing ribs to the sleeve body by setting clamping parts, and can quickly complete the fixing of the reinforcing ribs without welding operations; the elastic buffer layer can not only increase the friction with the reinforcing ribs and prevent relative sliding, but also play a buffering role when the wall is subjected to stress and deformation, reducing the rigid collision between the reinforcing ribs and the clamping parts, and reducing the risk of damage.

[0024] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All inventions utilizing the concept of this utility model are protected.

[0025] like Figures 1-2 As shown, the present invention provides a three-way sleeve grouting connector, which includes a grouting body 1. The grouting body 1 has a hollow and closed structure. The grouting body 1 is provided with a grouting port 2 with a cap and multiple hinged connectors 3. The multiple hinged connectors 3 are respectively arranged along the X, Y and Z axes. Each hinged connector 3 is hinged with a sleeve body 4. Each hinged connector 3 and its sleeve body 4 are connected to the grouting body 1. Each sleeve body 4 has a clamping member 6 for clamping a reinforcing rib 5 at its free end. The end portion of the reinforcing rib 5 is located inside the sleeve body 4.

[0026] As a specific arrangement of the hinged connector 3, such as Figure 3As shown, each of the hinged connectors 3 includes a hollow connecting rod 31. One end of the hollow connecting rod 31 is connected to the interior of the grouting body 1, and the other end is provided with a connecting ball head 32. The connecting ball head 32 is provided with a through hole 33 that is connected to the interior of the hollow connecting rod 31. Each of the sleeve bodies 4 is provided with a ball hinge connector base 34 at its fixed end. The ball hinge connector base 34 is hinged to the connecting ball head 32. The ball hinge connector base 34 is provided with a grouting channel 35 that is connected to the interior of the sleeve body 4.

[0027] A locking element 7 is also provided on the side of the ball joint connector base 34 near the connecting ball head 32. The locking element 7 includes a locking plate 71 and a locking cylinder 72. A circular hole 73 is provided through the middle of the locking plate 71. The diameter of the circular hole 73 is larger than the diameter of the hollow connecting rod 31 and smaller than the ball diameter of the connecting ball head 32. One end of the locking cylinder 72 is fixedly provided on the end face of the locking plate 71. The circular hole 73 is located inside the locking cylinder 72. The outer wall of the locking cylinder 72 is provided with external threads.

[0028] A threaded hole 8 is provided on the end face of the ball joint connector base 34 along its own length direction. The locking cylinder 72 is threadedly connected to the ball joint connector base 34 through the external thread and the threaded hole 8. When the locking plate 71 is turned, the locking cylinder 72 engages with the threaded hole 8, causing the locking plate 71 to move toward the connecting ball head 32 until the round hole 73 in the locking plate 71 comes into tight contact with the outer contour surface of the connecting ball head 32, thereby fixing the angle of the hinge connector 3 and the sleeve body 4 connected to it.

[0029] By setting multiple hinged connectors 3 for connecting the sleeve body 4 in the grouting body 1, the angle of the sleeve body 4 and the reinforcing rib 5 connected to the sleeve body 4 can be adjusted. This can adapt to irregular masonry joints of different angles in the stone masonry load-bearing wall, break the limitations of the traditional fixed-angle sleeve body 4, expand the applicable scenarios of the connector, make angle adjustment and grouting control convenient, simplify construction steps, shorten the construction cycle, and significantly improve the reinforcement efficiency of the stone masonry load-bearing wall.

[0030] Preferably, but not limited to, each of the sleeve bodies 4 is provided with a vent 9 communicating with its interior, and the vent 9 is positioned close to the clamping member 6. For example... Figure 5 As shown, each of the sleeve bodies 4 has multiple circumferentially spaced guide grooves 10 evenly arranged inside, and each guide groove 10 is arranged along the length direction of the sleeve body 4. By providing an exhaust port 9 on the sleeve body 4 and providing multiple guide grooves 10 inside the sleeve body 4, the grouting process of the sleeve body 4 is made smoother, and the multiple guide grooves 10 guide the epoxy resin to be evenly distributed, strengthening the fixing effect on the reinforcing rib 5.

[0031] like Figure 4As shown, as a specific arrangement of the clamping member 6, the clamping member 6 includes two clamping pieces 61 disposed at the free end of the sleeve body 4. A gap is provided between the two clamping pieces 61. After the two clamping pieces 61 are combined, they form an outer contour of frustum shape. The bottom of the two clamping pieces 61 is fixedly connected to the free end of the sleeve body 4. The interior of the two clamping pieces 61 is a cylindrical hollow structure. The diameter of the hollow interior of the two clamping pieces 61 is larger than the diameter of the reinforcing rib 5. The reinforcing rib 5 is disposed in the hollow interior of the two clamping pieces 61. Two mounting ears 62 are symmetrically arranged on both sides of the outer wall of each clamping piece 61. The positions of the mounting ears 62 of the two clamping pieces 61 match.

[0032] Furthermore, an elastic buffer layer 11 is provided on the inner wall of each of the two clamping pieces 61, and the inner surface of the elastic buffer layer 11 is provided with anti-slip texture. By setting the clamping member 6, the reinforcing rib 5 is initially clamped and fixed to the sleeve body 4, and the fixing of the reinforcing rib 5 can be completed quickly without welding. The elastic buffer layer 11 can not only increase the friction with the reinforcing rib 5 to prevent relative sliding, but also play a buffering role when the wall is deformed by force, reducing the rigid collision between the reinforcing rib 5 and the clamping member 6, and reducing the risk of damage.

[0033] The clamping component 6 specifically achieves the clamping of the reinforcing rib 5 as follows: the bolt in the bolt connector is passed through the two mounting ears 62 on the two clamping plates 61, and the nuts are tightened. The bolt connector causes the two clamping plates 61 to move towards each other, which compresses the gap between the two clamping plates 61 and reduces the diameter of the hollow interior of the two clamping plates 61, thereby achieving the clamping and fixing of the reinforcing rib 5 inside the two clamping plates 61. It does not need to be fixed to the wall joint, and the clamping is convenient during construction.

[0034] Furthermore, the outer surfaces of the grouting body 1, the hinged connector 3, and the clamping member 6 are all coated with an anti-corrosion coating, which extends the service life of the entire three-way sleeve grouting connector in humid environments, and is especially suitable for stone masonry houses in coastal areas.

[0035] The method of using a three-way sleeve grouting connector in this utility model is as follows: Construction preparation: Adjust the position of the upper sleeve 4 of the grouting body 1 according to the actual angle of the masonry joint of the stone load-bearing wall.

[0036] Embedded connectors: Multiple three-way sleeve grouting connectors are embedded into the intersecting horizontal and vertical masonry joints of the stone masonry load-bearing wall, ensuring that the multiple sleeves 4 are located in the horizontal masonry joint, the vertical masonry joint, and the masonry joint in the wall thickness direction, respectively, with an embedding depth of not less than 100mm.

[0037] Inserting the reinforcing rib 5: Insert the reinforcing rib 5 into the clamping parts 6 of the three sleeve bodies 4 respectively. After adjusting the position of the reinforcing rib 5, tighten the bolts of each clamping part 6 so that the clamping piece 61 clamps the reinforcing rib 5 and the elastic buffer layer 11 fits tightly with the reinforcing rib 5.

[0038] Grouting operation: Connect the interface of the grouting equipment to the grouting port 2, inject epoxy resin into the grouting body 1 until the epoxy resin overflows from the vent port 9 at the end of the sleeve body 4, indicating that the grouting is full, and then turn off the grouting equipment.

[0039] Forming the skeleton: After the epoxy resin has cured, multiple three-way sleeve grouting connectors and reinforcing ribs 5 form a complete reinforcing rib 5 skeleton, which is attached to the stone masonry load-bearing wall to improve the overall integrity and seismic bearing capacity of the wall.

[0040] In summary, the three-way sleeve grouting connector of this utility model effectively solves the problems of poor adaptability, unstable grouting and unreliable clamping in the prior art, significantly improves the reinforcement effect and construction efficiency of stone masonry load-bearing walls, and has good practicality and promotion value.
