[0002] With the improvement of people's living standards, people's requirements for buildings are also getting higher and higher, and the wallboard connecting structure is an important part of the building industry, which directly relates to the overall performance, safety and aesthetics of the building.

[0003] The traditional wallboard connecting structure is built layer by layer by mortar with materials such as bricks and blocks to form the structure of the wall. The advantage of this construction technology is that it is simple to construct and has low cost, but the disadvantage is that the wall is heavy, has poor seismic performance, and the construction speed is slow. With the acceleration of industrialization, prefabricated wallboards have been widely used in the construction field. The main forms of prefabricated wallboard connecting structure include welding, bolt connection, bonding and mortise and tenon connection. Welding connects the metal materials together by high temperature to form a solid connection point; bolt connection fixes the wallboard through bolts and nuts; bonding connection uses structural adhesive and other adhesive materials to bond the wallboard; mortise and tenon connection is a traditional wooden structure connection method, which realizes connection through the cooperation of tenon and mortise hole. The advantages of these prefabricated wallboard connecting structures are fast construction speed, high precision and reduced on-site work quantity, but at the same time, there are some problems such as the durability, seismic performance and construction quality of the connection point.

[0035] Optionally, the double-sleeve connection structure is set on the transverse reinforcing bar, and the connecting screw 2 is used to fix the two reinforcing bars together. A part of the mechanical sleeve 1 is sleeved on the transverse reinforcing bar 3, and the other part is sleeved on the connecting screw 2.

[0036] Optionally, the ratio of the length of the mechanical sleeve 1 to the diameter of the transverse reinforcing bar 3 is greater than or equal to a first preset ratio. The range of the first preset ratio is 2:1 to 5:1. The value of the first preset ratio can be set according to actual business needs and is not limited here. For example, the first preset ratio can be 2.7:1, that is, the length of the mechanical sleeve 1 is greater than or equal to 2.7 times the diameter of the transverse reinforcing bar 3.

[0037] Optionally, the ratio of the length of the left threaded end 21 to the diameter of the transverse reinforcing bar 3 is greater than or equal to a second preset ratio. The range of the second preset ratio is 1:1 to 2:1. The value of the second preset ratio can be set according to actual business needs and is not limited here.

[0038] Optionally, the left threaded end 21 and right threaded end 22 on the connecting screw 2 can be obtained by overlaying and thread rolling. The section of the rebar requiring overlaying is selected, and overlaying equipment is used to apply pressure to that section, increasing its diameter. After overlaying, a thread rolling wheel is used to roll the rebar to form threads. The threaded structure obtained through overlaying and thread rolling facilitates connection with other components, improving the connection strength between the rebar and the connecting components. Compared to traditional methods such as lap splicing, overlaying and thread rolling reduces the workload and time costs on the construction site.

[0039] In an optional embodiment, the wall panel includes an upper wall panel and a lower wall panel, wherein the first longitudinal steel bar 41 is located at the bottom of the upper wall panel and the second longitudinal steel bar 42 is located at the top of the lower wall panel.

[0041] Optionally, the cold-rolled portion 51 and the grouting portion 52 of the grouting sleeve 5 are integrally formed. The cold-rolled portion 51 is cold-rolled onto the second longitudinal steel bar 42. Through the cold rolling process, the surface of the steel bar will undergo plastic deformation, which increases the friction between the steel bar and the sleeve, thereby improving the overall strength of the connection and the mechanical properties of the connection. Single-end cold rolling can help ensure that the steel bar is inserted into the sleeve in the correct position and direction, and ensure that the connection can still maintain its integrity when subjected to vibration, which helps to maintain the stability and safety of the structure.

[0042] Optionally, the length of the cold-rolled portion 51 is a second preset length, and the ratio of the second preset length to the first preset length is in the range of 1:1 to 3:1.

[0043] A double-sleeve connection structure is installed on the transverse reinforcing bars in the wall panel, and a grouting sleeve connection structure is installed on the longitudinal reinforcing bars in the wall panel. The grouting sleeve connection ensures uniform filling between the reinforcing bars and the sleeve, reducing gaps, while the double-sleeve provides a stable mechanical connection. The combination of the two can improve the overall construction quality, ensure the reliability and durability of the reinforcing bar connection. The double-sleeve provides a mechanical connection, while the grouting sleeve strengthens the connection by filling with grout material. The combination of the two can resist various external forces and help improve the overall performance of the structure. Moreover, the double-sleeve is quick to install, while the grouting sleeve can be used for more complex connections. The combined use can improve construction efficiency.

[0044] In an optional embodiment, the transverse reinforcing bar 3 includes a first transverse reinforcing bar 31 and a second transverse reinforcing bar 32, the connecting threaded rod 2 is located between the first transverse reinforcing bar 31 and the second transverse reinforcing bar 32, and the mechanical sleeve 1 includes a first mechanical sleeve 11 and a second mechanical sleeve 12, the first mechanical sleeve 11 is sleeved on the first transverse reinforcing bar 31 and the connecting threaded rod 2, and the second mechanical sleeve 12 is sleeved on the second transverse reinforcing bar 32 and the connecting threaded rod 2.

[0045] In an optional embodiment, the length of the first mechanical sleeve 11 is the same as the length of the second mechanical sleeve 12.

[0046] In an optional embodiment, a first threaded end 311 is provided at the end of the first transverse reinforcing bar 31 near the connecting thread rod 2, and a second threaded end 321 is provided at the end of the second transverse reinforcing bar 32 near the connecting thread rod 2. The length of the first threaded end 311 is the same as the length of the left threaded end 21.

[0047] Optionally, the first threaded end 311 and the second threaded end 321 can also be obtained by the aforementioned overburdening and thread rolling method.

[0048] Optionally, the first mechanical sleeve 11 is sleeved on the first threaded end 311 of the first transverse steel bar 31 and the left threaded end 21 of the connecting screw 2, and the second mechanical sleeve 12 is sleeved on the second threaded end 321 of the second transverse steel bar 32 and the right threaded end 22 of the connecting screw 2.

[0049] Optionally, the first transverse reinforcing bar 31 and the second transverse reinforcing bar 32 are connected by connecting screw 2 and two mechanical sleeves 1. The mechanical sleeve 1 provides a standardized joint, ensuring the performance consistency of each joint and reducing quality fluctuations caused by improper manual operation. Using mechanical sleeves and connecting screws can greatly speed up construction, reduce downtime during construction, and improve construction efficiency.

[0050] In an optional embodiment, the length of the first threaded end 311 in the mechanical sleeve 1 is the same as the length of the left threaded end 21 in the mechanical sleeve, and the length of the second threaded end 321 in the mechanical sleeve 1 is the same as the length of the right threaded end 22 in the mechanical sleeve.

[0051] Optionally, the first mechanical sleeve 11 is centered relative to the first threaded end 311 and the left threaded end 21, and the first mechanical sleeve 12 is centered relative to the second threaded end 321 and the right threaded end 22.

[0052] In an optional embodiment, the connecting screw 2 further includes a connecting portion 23, which is located between the left threaded end 21 and the right threaded end 22, and the connecting portion 23, the left threaded end 21, and the right threaded end 22 are integrally formed.

[0053] Optionally, the left threaded end 21 and the right threaded end 22 of the connecting screw 2 have threaded structures obtained by the overlay and thread rolling method, while the middle connecting part 23 has no threaded structure. Other components can be easily connected to both ends of the screw through the threads, and the threads allow the effective length of the screw to be adjusted within a certain range to adapt to different working requirements. The smooth part can serve as a guide rail to guide the moving parts to move along a precise path.

[0054] In an optional embodiment, the cold-rolled portion 51 is located at one end of the grouting sleeve 5, and the diameter of the cold-rolled portion 51 is smaller than the diameter of the grouting portion 52.

[0055] Optionally, the cold-rolled portion 51 of the grouting sleeve 5 is used to enhance the anchoring force and bonding performance between the concrete and the reinforcing steel. The diameter of the cold-rolled portion 51 is smaller than the diameter of the grouting portion 52. Grout is injected into the sleeve in the gap between the grouting portion 52 and the first longitudinal reinforcing steel 41. Since the diameter of the cold-rolled portion is smaller, the grout will fill this part first and then gradually expand to the grouting portion with a larger diameter. This helps to ensure the uniform distribution of the grout and avoid voids. At the same time, this change in diameter forms a conical structure, which can produce a wedge effect during grouting, so that the grout generates a greater bond force to the reinforcing steel during the curing process, thereby improving the stability of the connection.

[0056] In an optional embodiment, the length of the grouting portion 52 fitted onto the first longitudinal steel bar 41 is in a ratio to the diameter of the longitudinal steel bar 4 that is greater than or equal to a third preset ratio, wherein the third preset ratio is 10:1-20:1.

[0057] Optionally, the third preset ratio can be set according to actual business needs, and is not limited here. For example, the third preset ratio can be 11:1, that is, the length of the grouting portion 52 fitted on the first longitudinal steel bar 41 is greater than or equal to 11 times the diameter of the longitudinal steel bar 4.

[0058] In an optional embodiment, the length of the grouting portion 52 fitted onto the second longitudinal steel bar 42 is in a ratio to the diameter of the longitudinal steel bar 4 that is greater than or equal to a fourth preset ratio, wherein the fourth preset ratio is 5:1-10:1.

[0059] Optionally, the fourth preset ratio can be set according to actual business needs, and is not limited here. For example, the fourth preset ratio can be 6:1, that is, the length of the grouting portion 52 fitted on the second longitudinal steel bar 42 is greater than or equal to 6 times the diameter of the longitudinal steel bar 4.
