Abstract
Description
Technical Field
[0001] The present invention relates to the field of construction technology, and particularly to a connection structure. Background Art
[0002] As an important part of the interior and exterior decoration of modern buildings, the construction quality of wall panels directly affects the aesthetics, practicability and durability of buildings. During the installation of wall panels, the treatment of vertical joints is particularly crucial, which not only relates to the overall visual effect of the wall surface, but also involves the waterproofing, heat insulation and stability of the wall body.
[0003] At present, the treatment of vertical joints in wall panels usually uses methods such as lap joint length connection of steel bars, electric welding connection, mortar filling method, and joint strip covering method. Connection construction methods such as lap joint length connection of steel bars and electric welding connection have relatively wide vertical joints and a large amount of on-site wet construction work. The mortar filling method is a traditional joint treatment method, which uses cement mortar or other special caulking materials to fill the gaps between wall panels. The mortar filling method has high requirements for the operation skills of construction workers, and it is difficult to ensure the uniformity of the joint width. The mortar may shrink during the drying process, resulting in cracks at the joints, affecting the aesthetics and stability of the wall surface; the joint strip covering method installs special joint strips at the joints and then performs sealing treatment to cover the joints and improve the aesthetics. Using special joint strips will increase the material cost, and at the same time, the color and texture may be different from those of the wall panels, affecting the overall aesthetics of the wall surface.
[0004] Therefore, it is particularly important to develop a joint connection structure that can reduce the working width of the vertical joint connection of wall panels, improve the stability and durability of wall panels, increase the aesthetics of the exterior of wall panels, and reduce the amount of on-site wet construction work and the shrinkage rate of materials. Summary of the Invention

[0033] Due to the problems that the currently used connection structure has a relatively large working width for the vertical joints of wall panels, which cannot ensure the stability, durability, and aesthetics of the wall panels, and there is a relatively large amount of wet work in on-site construction. Therefore, in order to reduce the working width of the vertical joint connection of the wall panels, improve the stability and durability of the wall panels, and at the same time increase the aesthetics of the wall panels, the present application provides a connection structure.
[0034] Please refer to Figure 1 , Figure 1 which is a schematic diagram of a connection structure assembly proposed according to an embodiment of the present invention. The connection structure provided by the present application is used to connect the vertical joints between adjacent wall panels, and the connection structure includes:
[0035] Hook and loop component 1, the hook and loop component 1 includes a straight part of the hook and loop and a bent part 13 of the hook and loop. The shape of the hook and loop component 1 is U-shaped. A preset part on the straight part of the hook and loop is located inside the wall panel, and the remaining part of the straight part of the hook and loop except the preset part and the bent part 12 of the hook and loop are located in the vertical joint between the wall panels;
[0036] Pin and anchor component 2, the pin and anchor component 2 includes a first pin and anchor straight part 21, a second pin and anchor straight part 22, and a pin and anchor bent part 23. The shape of the pin and anchor component 2 is U-shaped. The diameter of the pin and anchor component is equal to the diameter of the hook and loop component. The first pin and anchor straight part 21 and the second pin and anchor straight part 22 are respectively inserted into the bent parts 13 of two adjacent hook and loop components 1 in the horizontal direction to connect two adjacent hook and loop components 1 in the horizontal direction;
[0037] Fixing component, the fixing component is sleeved on the first pin and anchor straight part 21 and the second pin and anchor straight part 22. The fixing component is used to fixedly connect the hook and loop component 1 and the pin and anchor component 2.
[0038] Optionally, the width of the vertical joint of the wall panel can be set according to actual business requirements and is not limited herein. Exemplarily, the width of the vertical joint of the wall panel can be greater than or equal to 70 mm.
[0039] Optionally, a part of the hook and loop component 1 is fixed in the wall panel, and the other part is exposed in the vertical joint of the wall panel. The two straight parts of the hook and loop and the bent part 13 of the hook and loop form a U shape.
[0040] Optionally, the hook and loop component 1 is formed by bending one end of the horizontal reinforcement in the wall panel.
[0041] Optionally, the hook and loop component 1 can be uniformly manufactured by using a professional machine to form the reinforcing bar heads of the whole panel at one time. Mark the reserved length at one end of the horizontal reinforcement in the wall panel, and then bend it to form the hook and loop component 1. The diameter of the bent part 13 of the hook and loop can be set according to actual business requirements and is not limited herein.
[0042] Optionally, the length of the straight part of the hook and loop located inside the wall panel can be set according to actual business requirements and is not limited herein.
[0043] Optionally, the first pin and anchor straight part 21, the second pin and anchor straight part 22, and the pin and anchor bent part 23 of the pin and anchor component 2 form a U shape, and the straight part of the pin and anchor component 2 is inserted into the bent part 13 of the hook and loop component 1.
[0044] Optionally, after the pin and anchor component 2 is inserted into the bent part 13 of the hook and loop component 1, the hook and loop component 1 and the pin and anchor component 2 are fixedly connected through the fixing component.
[0045] Optionally, the strength of the pin-anchoring component 2 needs to be greater than or equal to the strength of the horizontal reinforcement bars of the wall panel.
[0046] By arranging the hook-ring component 1 and the pin-anchoring component 2 in the vertical joint between adjacent wall panels, after the pin-anchoring component 2 is inserted into the hook-ring bend 13 of the hook-ring component 1, it is fixed by the fixing component. This connection method simplifies the installation process of the wall panel, reduces complex construction steps, improves construction efficiency, and the connection method between the pin-anchoring component 2 and the hook-ring component 1 has high mechanical stability, can effectively resist the shear force and tensile force between the wall panels, ensure the firmness of the connection between the wall panels, and compared with the traditional steel bar lapping or electric welding connection, the connection between the pin-anchoring component 2 and the hook-ring component 1 can reduce the width of the construction joint, improve the compactness between the wall panels, thereby enhancing the integrity and aesthetics of the wall body.
[0047] In an optional embodiment, the distance between the inner side of the hook-ring bend 13 and the side elevation of the wall panel is 25 mm - 50 mm.
[0048] Optionally, the distance between the inner side of the hook-ring bend 13 and the side elevation of the wall panel can be set according to actual business requirements and is not limited herein. Exemplarily, the distance between the inner side of the hook-ring bend 13 and the side elevation of the wall panel can be 30 mm, that is, during precast pouring, the hook-ring component 1 is exposed 30 mm outside the side of the wall panel, and is installed vertically corresponding and positioned and corrected and fixed.
[0049] Optionally, the distances that two adjacent hook-ring components 1 are exposed outside the side of the wall panel in the horizontal direction are the same.
[0050] Exposing the hook-ring component 2 30 mm outside the side of the wall panel can facilitate the insertion of the pin-anchoring component 2. The exposed length of 30 mm provides a clear positioning for the insertion of the pin-anchoring component 2, ensuring that the pin-anchoring component 2 can be accurately inserted into the hook-ring component 1, thereby improving the splicing accuracy of the wall panel, reducing construction errors, and at the same time, the exposed part of the hook-ring component can be directly observed and inspected, facilitating the construction personnel to confirm whether the connection is firm.
[0051] In an optional embodiment, the hook-ring straight part includes a first hook-ring straight part 11 and a second hook-ring straight part 12. The length of the first hook-ring straight part 11 is greater than the length of the second hook-ring straight part 12, and the first hook-ring straight part 11, the second hook-ring straight part 12, and the hook-ring bend 13 are integrally formed.
[0052] Optionally, the hook-ring component 1 is formed by calibrating and reserving a length at one end of the horizontal reinforcement bar and then bending it. The lengths of the first hook-ring straight part 11 and the second hook-ring straight part 12 are different, ensuring that a preset part of the second hook-ring straight part 12 is also located inside the wall panel.
[0053] Optionally, the lengths of the first hook straight portion 11 and the second hook straight portion 12 can also be the same. After reserving the hook bend portion 13 in the middle of the horizontal reinforcement of the wall panel, it is bent to form the hook assembly 1. Making the length of the first hook straight portion 11 greater than the length of the second hook straight portion 12 can reduce material waste and lower costs.
[0054] In an alternative embodiment, the fixing assembly includes a clamping device 3, a cushioning device, and a fastening device 5. The cushioning device includes a first cushioning device 41. On the first pin anchoring straight portion 21 and the second pin anchoring straight portion (22), from one end close to the pin anchoring assembly 2 to the other end, the clamping device 3, the first cushioning device 41, and the fastening device 5 are sequentially sleeved.
[0055] In an alternative embodiment, the clamping device 3 is a steel plate clamp. The first cushioning device 41 includes a first steel gasket and a second steel gasket. The fastening device 5 is a nut.
[0056] Optionally, the shapes and sizes of the steel plate clamp and the steel gasket can be set according to actual business requirements and are not limited herein. Exemplarily, the shapes of the steel plate clamp and the 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 assembly 1 and the pin anchoring assembly 2 together through the clamping force. The steel plate clamp clamps the workpiece by mechanical force and generates sufficient clamping force using the extrusion principle, so that the workpiece remains in a fixed position and does not displace during the processing. And the steel plate clamp is usually designed with a large contact area, which can disperse the pressure applied to the workpiece and avoid local damage to the workpiece.
[0058] Optionally, the first cushioning device 41 includes a first steel gasket and a second steel gasket. After the steel plate clamp is fixed, the steel gaskets are placed between the steel plate clamp and the nut, and then the nut is tightened. The nut applies pressure to the gaskets, and the gaskets then evenly transfer this pressure to the steel plate clamp and the workpiece to be fixed. The steel gaskets can adjust the distance between the nut and the workpiece to ensure that the steel plate clamp can maintain an appropriate clamping force after the nut is tightened. The gaskets can prevent the nut from directly contacting the workpiece, improve work efficiency and safety, and reduce wear and scratches, thereby improving the fixing effect.
[0059] In an alternative embodiment, the steel plate clamp is provided with a first oblong hole and a second oblong hole. The diameters of the first oblong hole and the second oblong hole are greater than the diameter of the pin anchoring assembly. The first steel gasket is provided with a first pin, and the second steel gasket is provided with a second pin. The first pin anchoring straight portion 21 sequentially passes through the first oblong hole and the first pin, and the second pin anchoring straight portion 22 sequentially passes through the second oblong hole and the second pin.
[0060] Optionally, the size of the oblong hole can be set according to actual business requirements and is not limited herein. Exemplarily, the diameter of the oblong hole is greater than the diameter of the straight part of the hook ring.
[0061] Optionally, after the pin anchor assembly 2 is inserted into the bent part 13 of the hook ring of the hook ring assembly 1, it is clamped with a clamping device 3, i.e., a steel plate clamp. A steel gasket is placed between the steel plate clamp and the nut, and then the nut is tightened.
[0062] In an alternative embodiment, the fastening device 5 includes a first nut 51 and a second nut 52. A first thread structure is provided on the first pin anchor straight part 21, and a second thread structure is provided on the second pin anchor straight part 22. The first nut 51 is fixed to the first pin anchor straight part 21 through the first thread structure, and the second nut 52 is fixed to the second pin anchor straight part 22 through the second thread structure.
[0063] Optionally, thread structures are provided on the outer parts of both the first pin anchor straight part 21 and the second pin anchor straight part 22 to cooperate with the nut. The diameters of the first pin anchor straight part 21 and the second pin anchor straight part 22 can be set according to actual business requirements and are not limited herein. Exemplarily, the first pin anchor straight part 21 and the second pin anchor straight part 22 can be structures with a diameter of 8 mm and threads. The design of the threads enables the fastener to generate an axial force during the screwing process, thereby achieving the purpose of fastening or anchoring.
[0064] Optionally, the inner diameter of the nut conforms to the diameter of the straight part of the pin anchor. Exemplarily, in the case where the first pin anchor straight part 21 and the second pin anchor straight part 22 are structures with a diameter of 8 mm and threads, the nut is an M8 nut, i.e., a metric nut with a thread diameter of 8 mm, for use in cooperation with the pin anchor assembly 2 with an M8 thread.
[0065] Optionally, after clamping with the clamping device 3, i.e., the steel plate clamp, and inserting the first gasket device 41, i.e., the steel gasket, the steel gasket 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 ring assembly 1 and the pin anchor assembly 2.
[0066] The pin anchor assembly 2 with a thread structure has the advantages of convenient installation, good tensile and shear resistance, and can provide a stable fixing effect.
[0067] In an alternative embodiment, the gasket device further includes a second gasket device 42, and the second gasket device 42 is disposed in the cavity formed by the outer sides of the bent parts 13 of two adjacent hook ring assemblies 1 in the horizontal direction and the inner side of the pin anchor bent part 23.
[0068] In an alternative embodiment, the second cushioning device 42 is a round steel pad head, and the length of the round steel pad head is greater than or equal to the diameter of the outer side of the pin anchor bend 23.
[0069] Optionally, the second cushioning device 42 is a round steel pad head, and the round steel pad head is disposed in the cavity formed by the opposite surfaces of the outer sides of the hook ring bends 13 of two horizontally adjacent hook ring assemblies 1 and the inner side of the pin anchor bend 23 of the pin anchor assembly 2.
[0070] Optionally, the round steel pad head is a mechanical part used below a fastener to provide a uniform pressure distribution, increase the support area or adjust the gap between components. The circular design of the round steel pad head helps to evenly distribute the pressure applied by the nut to the contact surface, reducing local stress concentration. The round steel pad head helps to improve the stability and structural strength of the connection, and when the flatness of the two hook ring bends 13 is not high, the round steel pad head can make the connection tighter, improving the reliability and durability of the connection.
[0071] In an alternative embodiment, the first hook ring straight portion 11 and the second hook ring straight portion 12 are parallel, and a metal tie wire is wound around the first hook ring straight portion 11 and the second hook ring straight portion 12 located in the wall panel to fix the forces borne by the first hook ring straight portion 11 and the second hook ring straight portion 12.
[0072] Optionally, at a preset position of the portions of the first hook ring straight portion 11 and the second hook ring straight portion 12 located within the wall panel, the first hook ring straight portion 11 and the second hook ring straight portion 12 are tied tightly using a metal tie wire. The preset position can be set according to actual business requirements and is not limited herein.
[0073] Optionally, the material, diameter and number of winding strands of the metal tie wire can be set according to actual business requirements and are not limited herein. Exemplarily, the first hook ring straight portion 11 and the second hook ring straight portion 12 can be tied tightly using a wire with a diameter of 1.8 mm, and the number of winding strands of the wire is greater than three strands.
[0074] Optionally, after tying the first hook ring straight portion 11 and the second hook ring straight portion 12 tightly, the prefabricated hook ring assembly 1 is cast into the wall panel to ensure the tensile anchoring strength.
[0075] The tie wire can be tightly wound around the first hook ring straight portion 11 and the second hook ring straight portion 12, thereby providing additional gripping force. The tie wire fixation can also ensure that the hook ring assembly 1 will not accidentally fall off when bearing tension or pressure, improving the operation safety and the overall stability of the structure.
[0076] Optionally, after the hook-and-loop assembly 1 and the pin anchor assembly 2 are connected and fixed, a shaped lightweight formwork is used at the vertical joint of the wall panel for pouring and filling to form an integral force-bearing shear wall structure. The strength of the grouting material for pouring is greater than or equal to the strength of the wall panel concrete.
[0077] Please refer to Figure 2 、 Figure 3 , Figure 2 which is a top view of the connection structure according to an embodiment of the present invention, Figure 3 and which is a side view of the connection structure according to an embodiment of the present invention. Hereinafter, a connection structure and method provided by the embodiments of the present application will be described integrally:
[0078] The connection structure includes a hook-and-loop assembly 1, a pin anchor assembly 2 and a fixing assembly. The hook-and-loop assembly 1 and the pin anchor assembly 2 are both U-shaped. The hook-and-loop assembly 1 is made by using a professional machine to form the reinforcing bar heads of the whole plate cage at one time. During precast pouring, the hook-and-loop assembly 1 is exposed 30 mm from the side of the wall panel. The first pin anchor straight part 21 and the second pin anchor straight part 22 of the pin anchor assembly 2 are respectively inserted into the hook-and-loop bent parts 13 of two hook-and-loop assemblies 1, passed through the clamping device 3, and clamped with the clamping device 3, that is, a steel plate clamp. Then, a first cushioning device 41, that is, a steel gasket, is passed through. The steel gasket is located between the steel plate clamp and the nut. The second cushioning device 42 is a round steel pad head. The round steel pad head is arranged on the opposite outer sides of the hook-and-loop bent parts 13 of two horizontally adjacent hook-and-loop assemblies 1 and the inner side of the pin anchor bent part 23 of the pin anchor assembly 2, and the cavity formed by the three is padded. The first nut 51 and the second nut 52 are respectively tightened to complete the fixation of the hook-and-loop assembly 1 and the pin anchor assembly 2. When the hook-and-loop assembly 1 and the pin anchor assembly 2 are connected and fixed, a shaped lightweight formwork is used at the vertical joint of the wall panel for pouring and filling to form an integral force-bearing shear wall structure.
[0079] The connection structure provided by the present application is used to connect the vertical joints between adjacent wall panels. The connection structure includes: a hook and loop component 1, which includes a hook and loop straight part and a hook and loop bent part 13. The shape of the hook and loop component 1 is U-shaped.
