Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a connection structure. Background Technology

[0002] As an important component of modern building interior and exterior decoration, the construction quality of wall panels directly affects the aesthetics, practicality, and durability of buildings. During wall panel installation, the treatment of vertical joints is particularly crucial, as it not only relates to the overall visual effect of the wall but also to the wall's waterproofing, insulation, and stability.

[0003] Currently, the treatment of vertical joints in wall panels typically involves methods such as rebar lap length connection, electric welding, mortar filling, and joint strip covering. Rebar lap length connection and electric welding methods result in wider vertical joints and a significant amount of wet work during on-site construction. Mortar filling is a traditional method, using cement mortar or other specialized filler materials to fill the gaps between wall panels. This method requires skilled workers, and ensuring uniform joint width is difficult. Furthermore, the mortar may shrink during drying, leading to cracks at the joints and affecting the wall's aesthetics and stability. Joint strip covering involves installing specialized joint strips at the joints and then sealing them to conceal the joints and improve aesthetics. However, using specialized joint strips increases material costs, and their color and texture may differ from the wall panels, affecting the overall appearance of the wall.

[0004] Therefore, it is particularly important to develop a joint connection structure that can reduce the working width of vertical joints in wall panels, improve the stability and durability of wall panels, enhance their aesthetics, and reduce the amount of wet work and material shrinkage during on-site construction.

[0033] Because the current connection structure has a large working width for vertical joints in the wall panels, it cannot guarantee the stability, durability, and aesthetics of the wall panels, and there is a lot of wet work involved in on-site construction. Therefore, in order to reduce the working width of vertical joints in wall panels, improve the stability and durability of the wall panels, and enhance their aesthetics, this application provides a connection structure.

[0034] Please see Figure 1 , Figure 1 This is a schematic diagram of a connection structure assembly according to an embodiment of the present invention. The connection structure provided in this application is used to connect the vertical joints between adjacent wall panels, and the connection structure includes:

[0035] Hook and loop assembly 1, the hook and loop assembly 1 includes a hook and loop straight part and a hook and loop bent part 13, the hook and loop assembly 1 is U-shaped, the preset part on the hook and loop straight part is located inside the wall panel, the remaining part on the hook and loop straight part other than the preset part and the hook and loop bent part 13 are located in the vertical joint between the wall panels;

[0036] The pin anchor assembly 2 includes a first pin anchor straight portion 21, a second pin anchor straight portion 22, and a pin anchor bent portion 23. The pin anchor assembly 2 is U-shaped, and the diameter of the pin anchor assembly is equal to the diameter of the hook and loop assembly. The first pin anchor straight portion 21 and the second pin anchor straight portion 22 are respectively inserted into the hook and loop bent portions 13 of two adjacent hook and loop assemblies 1 in the horizontal direction to connect the two adjacent hook and loop assemblies 1 in the horizontal direction.

[0037] A fixing component is sleeved on the first pin anchor straight part 21 and the second pin anchor straight part 22. The fixing component is used to fix the hook and ring assembly 1 and the pin anchor assembly 2.

[0038] Optionally, the width of the vertical joint of the wall panel can be set according to actual business needs, and is not limited here. For example, the width of the vertical joint of the wall panel can be greater than or equal to 70mm.

[0039] Optionally, a portion of the hook and loop assembly 1 is fixed in the wall panel, while another portion is exposed in the vertical seam of the wall panel. The two straight hook and loop bends 13 of the hook and loop assembly 1 form a U-shape.

[0040] Optionally, the hook and loop assembly 1 is formed by bending one end of a horizontal rib within the wall panel.

[0041] Optionally, the hook and ring assembly 1 can be uniformly manufactured by producing the reinforcing bars of a whole plate of wire mesh in one go using professional machinery. The length is marked and reserved at one end of the horizontal reinforcing bar inside the wall panel, and then bent to form the hook and ring assembly 1. The diameter of the hook and ring bend 13 can be set according to actual business needs and is not limited here.

[0042] Optionally, the length of the straight portion of the hook and loop inside the wall panel can be set according to actual business needs, and is not limited here.

[0043] Optionally, the first straight part 21, the second straight part 22, and the bent part 23 of the pin anchor assembly 2 form a U-shape, and the straight part of the pin anchor assembly 2 is inserted into the bent part 13 of the hook ring assembly 1.

[0044] Optionally, after the pin anchor assembly 2 is inserted into the hook ring bend 13 of the hook ring assembly 1, the hook ring assembly 1 and the pin anchor assembly 2 are fixedly connected by a fixing assembly.

[0045] Optionally, the strength of the pin anchor assembly 2 needs to be greater than or equal to the strength of the horizontal reinforcement bars of the wall panel.

[0046] By setting hook-and-anchor assembly 1 and pin-anchor assembly 2 in the vertical joint between adjacent wall panels, and inserting the pin-anchor assembly 2 into the hook-and-anchor bend 13 of the hook-and-anchor assembly 1, and then fixing it with a fixing component, this connection method simplifies the wall panel installation process, reduces complex construction steps, and improves construction efficiency. The connection between the pin-anchor assembly 2 and the hook-and-anchor assembly 1 has high mechanical stability and can effectively resist the shear and tensile forces between wall panels, ensuring the firmness of the wall panel connection. Compared with traditional steel bar lap or electric welding connections, the connection between the pin-anchor assembly 2 and the hook-and-anchor assembly 1 can reduce the width of the construction joint and increase the density between wall panels, thereby enhancing the integrity and aesthetics of the wall.

[0047] In an optional embodiment, the distance between the inner side of the hook bend 13 and the side facade of the wall panel is 25mm-50mm.

[0048] Optionally, the distance between the inner side of the hook bend 13 and the side facade of the wall panel can be set according to actual business needs, and is not limited here. For example, the distance between the inner side of the hook bend 13 and the side facade of the wall panel can be 30mm, that is, during precast casting, the hook assembly 1 is exposed 30mm from the side of the wall panel, and is installed and fixed in place according to the upper and lower parts.

[0049] Optionally, two adjacent hook and loop assemblies 1 in the horizontal direction are equidistant from the side of the wall panel.

[0050] The fact that the hook and ring assembly 2 protrudes 30mm from the side of the wall panel facilitates the insertion of the pin and anchor assembly 2. The 30mm protrusion provides a clear positioning for the insertion of the pin and anchor assembly 2, ensuring that the pin and anchor assembly 2 can be accurately inserted into the hook and ring assembly 1. This improves the accuracy of the wall panel splicing and reduces construction errors. At the same time, the exposed part of the hook and ring assembly can be directly observed and inspected, making it easy for construction personnel to confirm whether the connection is firm.

[0051] In an optional embodiment, the hook and loop straight portion includes a first hook and loop straight portion 11 and a second hook and loop straight portion 12, wherein the length of the first hook and loop straight portion 11 is greater than the length of the second hook and loop straight portion 12, and the first hook and loop straight portion 11, the second hook and loop straight portion 12, and the hook and loop curved portion 13 are integrally formed.

[0052] Optionally, the hook and ring assembly 1 is formed by marking a reserved length at one end of the horizontal rib and then bending it. The lengths of the first hook and ring straight part 11 and the second hook and ring straight part 12 are different, ensuring that the second hook and ring straight part 12 also has a preset part located inside the wall panel.

[0053] Optionally, the first hook straight portion 11 and the second hook straight portion 12 can also be the same length. The hook bend 13 is reserved in the middle of the horizontal rib of the wall panel and then bent to form the hook assembly 1. The length of the first hook straight portion 11 is greater than the length of the second hook straight portion 12, which can reduce material waste and lower costs.

[0054] In an optional embodiment, the fixing assembly includes a clamping device 3, a padding device, and a fastening device 5. The padding device includes a first padding device 41. The clamping device 3, the first padding device 41, and the fastening device 5 are sequentially sleeved on the first pin anchor section 21 and the second pin anchor section (22) from one end near the pin anchor assembly 2 to the other end.

[0055] In an optional embodiment, the clamping device 3 is a steel plate clamp, the first padding device 41 includes a first steel pad and a second steel pad, and the fastening device 5 is a nut.

[0056] Optionally, the shape and size of the steel plate clamp and steel gasket can be set according to actual business needs, and are not limited here. For example, the shape of the steel plate clamp and steel gasket can be rectangular or circular.

[0057] Optionally, the clamping device 3 is a steel plate clamp. The steel plate clamp can fix the hook ring assembly 1 and the pin anchor assembly 2 together by clamping force. The steel plate clamp clamps the workpiece by mechanical force and generates sufficient clamping force by extrusion principle, so that the workpiece remains in a fixed position during processing and does not shift. In addition, the steel plate clamp is usually designed with a large contact area, which can distribute the pressure applied to the workpiece and avoid causing local damage to the workpiece.

[0058] Optionally, the first shim device 41 includes a first steel shim and a second steel shim. After the steel plate clamp is fixed, the steel shim is placed between the steel plate clamp and the nut, and then the nut is tightened. The nut applies pressure to the shim, and the shim then evenly transmits this pressure to the steel plate clamp and the fixed workpiece. The steel shim can adjust the distance between the nut and the workpiece, ensuring that the steel plate clamp can maintain an appropriate clamping force after the nut is tightened. The shim can prevent the nut from directly contacting the workpiece, improving work efficiency and safety, reducing wear and scratches, and improving the fixing effect.

[0059] In an optional embodiment, the steel plate clamp is provided with a first elongated hole and a second elongated hole, the diameters of the first elongated hole and the second elongated hole being larger than the diameter of the pin anchor assembly. A first pin is provided on the first steel washer, and a second pin is provided on the second steel washer. The straight portion 21 of the first pin anchor passes through the first elongated hole and the first pin in sequence, and the straight portion 22 of the second pin anchor passes through the second elongated hole and the second pin in sequence.

[0060] Optionally, the size of the oblong hole can be set according to actual business needs, and is not limited here. For example, the diameter of the oblong hole is larger than the diameter of the straight part of the hook.

[0061] Optionally, after the pin anchor assembly 2 is inserted into the hook ring assembly 1, the hook ring bend 13 is clamped with the clamping device 3, i.e., the steel plate clamp, with the steel washer placed between the steel plate clamp and the nut, and then the nut is tightened.

[0062] In an optional embodiment, the fastening device 5 includes a first nut 51 and a second nut 52. The first pin anchor straight portion 21 is provided with a first threaded structure, and the second pin anchor straight portion 22 is provided with a second threaded structure. The first nut 51 is fixed to the first pin anchor straight portion 21 by the first threaded structure, and the second nut 52 is fixed to the second pin anchor straight portion 22 by the second threaded structure.

[0063] Optionally, both the first pin anchor section 21 and the second pin anchor section 22 are provided with threaded structures on their exteriors to cooperate with the nut. The diameters of the first pin anchor section 21 and the second pin anchor section 22 can be set according to actual business needs and are not limited here. For example, the first pin anchor section 21 and the second pin anchor section 22 can be threaded structures with a diameter of 8mm. The thread design allows the fastener to generate axial force during the tightening process, thereby achieving the purpose of fastening or anchoring.

[0064] Optionally, the inner diameter of the nut matches the diameter of the straight portion of the pin anchor. For example, when the first pin anchor straight portion 21 and the second pin anchor straight portion 22 are threaded structures with a diameter of 8 mm, the nut is an M8 nut, that is, a metric nut with a thread diameter of 8 mm, for use with the pin anchor assembly 2 with M8 threads.

[0065] Optionally, after clamping with the clamping device 3 (i.e., steel plate clamp) and inserting the first padding device 41 (i.e., steel washer), the steel washer is located between the steel plate clamp and the nut. Then, the first nut 51 and the second nut 52 are tightened respectively to complete the connection of the hook and ring assembly 1 and the pin and anchor assembly 2.

[0066] The threaded pin anchor assembly 2 has the advantages of easy installation, good tensile and shear strength, and stable fixing effect.

[0067] In an optional embodiment, the padding device further includes a second padding device 42 disposed on the outer side of the hook bends 13 of two adjacent hook assemblies 1 in the horizontal direction, and in the cavity formed with the inner side of the pin anchor bend 23.

[0068] In an optional embodiment, the second padding device 42 is a round steel pad head, the length of which is greater than or equal to the outer diameter of the pin anchor bend 23.

[0069] Optionally, the second padding device 42 is a round steel pad, which is disposed on the outer opposite surface of the hook bend 13 of two adjacent hook ring assemblies 1 in the horizontal direction, and on the inner side of the pin anchor bend 23 of the pin anchor assembly 2, in the cavity formed by the three.

[0070] Alternatively, a round steel pad is a mechanical part used under fasteners to provide uniform pressure distribution, increase support area, or adjust the gap between components. The round design of the round steel pad helps to distribute the pressure applied by the nut evenly on the contact surface, reducing local stress concentration. The round steel pad helps to improve the stability and structural strength of the connection, and when the flatness of the two hook bends 13 is not high, the round steel pad can make the connection tighter, improving the reliability and durability of the connection.

[0071] In an optional embodiment, the first hook and loop straight portion 11 and the second hook and loop straight portion 12 are parallel, and metal binding wire is wound around the first hook and loop straight portion 11 and the second hook and loop straight portion 12 located in the wall panel to fix the force on the first hook and loop straight portion 11 and the second hook and loop straight portion 12.

[0072] Optionally, the portions of the first hook straight portion 11 and the second hook straight portion 12 located inside the wall panel are secured with metal wire at a preset position. The preset position can be set according to actual business needs and is not limited here.

[0073] Optionally, the material, diameter, and number of strands of the metal binding wire can be set according to actual business needs and are not limited here. For example, a wire with a diameter of 1.8mm can be used to tie the first hook straight part 11 and the second hook straight part 12 tightly, and the number of strands of the wire is more than three.

[0074] Optionally, after the first hook straight portion 11 and the second hook straight portion 12 are tightened, the prefabricated hook assembly 1 is cast into the wall panel to ensure tensile anchoring strength.

[0075] By tightly wrapping the wire around the first hook and the second hook, the gripping force is increased. The wire fixing also ensures that the hook and loop assembly 1 will not fall off accidentally when subjected to tension or pressure, thereby improving operational safety and the overall stability of the structure.

[0076] Optionally, after the hook and ring assembly 1 and the pin and anchor assembly 2 are connected and fixed, a shaped lightweight mold is used to seal the vertical joint of the wall panel, and grouting is performed to fill and compact the joint to form an integral shear-resistant wall panel structure. The strength of the grouting material is greater than or equal to the strength of the wall panel concrete.

During precast casting, the hook and ring assembly 1 protrudes 30mm from the side of the wall panel. The first pin and anchor straight section 21 and the second pin and anchor straight section 22 of the pin and anchor assembly 2 are respectively inserted into the hook and ring bends 13 of the two hook and ring assemblies 1, and then inserted into the clamping device 3. The clamping device 3, i.e., the steel plate clamp, is used for clamping. Then, the first padding device 41, i.e., the steel gasket, is inserted, with the steel gasket located within the steel plate clamp. Between the nut and the second pad device 42 is a round steel pad. The round steel pad is set on the opposite outer side of the hook bend 13 of the two adjacent hook ring assemblies 1 in the horizontal direction, and on the inner side of the pin anchor bend 23 of the pin anchor assembly 2. The three are used to fill the cavity formed by the pad. The first nut 51 and the second nut 52 are tightened respectively to fix the hook ring assembly 1 and the pin anchor assembly 2. After the hook ring assembly 1 and the pin anchor assembly 2 are connected and fixed, a shaped lightweight mold is used to seal the vertical joint of the wall panel, and the wall panel is filled with water to form an integral shear-resistant wall panel structure.

[0079] The connection structure provided in this application is used to connect the vertical joints between adjacent wall panels. The connection structure includes: a hook and loop assembly 1, which includes a hook and loop straight portion and a hook and loop bent portion 13. The hook and loop assembly 1 is U-shaped.
