In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a communication between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0034] Combine Figures 1 to 5 As shown, the present invention provides a variable-angle assembled connection node for a wooden structure, comprising a first connection member 1 , a second connection member 2 and a threaded connection assembly 3 .

[0035] Combine Figures 1 to 5As shown, the first connecting member 1 includes a first annular column 11, the bottom surface of the first annular column 11 is a spiral descending surface, and the spiral descending surface is composed of 36 uniform step surfaces of the same size; the second connecting member 2 includes a second annular column 21, the top surface of the second annular column 21 is a spiral ascending surface, and the spiral ascending surface is composed of 36 uniformly distributed step surfaces of the same size connected end to end; the threaded connection assembly 3 positions and connects the first connecting member 1 and the second connecting member 2; the spiral descending surface of the first annular column 11 and the spiral ascending surface of the second annular column 21 are fitted together through the step surfaces thereon; for every step where the step surfaces of the first connecting member 1 and the second connecting member 2 are offset, the connection angle of the first connecting member 1 and the second connecting member 2 increases by 10 degrees.

[0036] In this embodiment, the two spiral rising surfaces are used as locking surfaces to press against each other. The spiral surface composed of evenly distributed step surfaces can improve the connection accuracy. The 360-degree circumference is divided into 36 steps, and each step corresponds to a 10-degree sector surface. When the first connecting member 1 and the second connecting member 2 are connected, the connection angle of the first connecting member 1 and the second connecting member 2 will increase by 10 degrees for each step offset. By controlling the number of offset steps, the final connection angle can be precisely controlled, and the actual connection result is more stable.

[0037] In this embodiment, the angle between the upper and lower wooden structures is less than 90 degrees, and the area of ​​the staggered steps is less than 1 / 4 of the total step area. This limitation ensures that the actual effective area of ​​the locking surface is at least 3 / 4 of the total area of ​​the spiral ascending surface, ensuring sufficient effective contact surface.

[0038] When the angle between the upper and lower wooden structures needs to be fixed to 90-180 degrees, the first connecting member 1 or the second connecting member 2 can be disassembled, rotated 90 degrees, and then re-fixed to the corresponding wooden structure to achieve assembly;

[0039] The above installation method enables the wooden structure prefabricated connection node to cope with a larger workload and has higher connection reliability.

[0040] In some embodiments, combined Figures 1 to 3 As shown, the variable-angle wooden structure prefabricated connection node also includes a mounting plate 12 and a positioning cone 23. The mounting plate 12 is integrally formed inside the first annular column 11, which can avoid exposing the first annular column 11 when the threaded connection component 3 is installed, thereby reducing the volume of the variable-angle wooden structure prefabricated connection node. At the same time, the threaded connection component 3 has a better fixing effect when the fixing distance is reduced. The positioning cone 23 is integrally formed inside the second annular column 21, and the top surface height of the positioning cone 23 exceeds that of the second annular column 21. The protruding positioning cone 23 is inserted into the interior of the first annular column 11, providing a positioning effect for the connection between the first connector 1 and the second connector 2.

[0041] In some embodiments, combined Figure 1 、 Figure 4 As shown, the threaded connection assembly 3 includes a bolt 31 and a nut 32. The mounting plate 12 and the positioning table 23 are both provided with mounting through holes. The bolt 31 passes through the mounting plate 12 and the positioning table 23 in sequence to connect the nut 32. There are two nuts 32, and the two nuts 32 respectively abut against the two ends of the positioning table 23. This connection method can produce a distance effect to ensure the stability of the connection between the first connecting member 1 and the second connecting member 2.

[0042] In some embodiments, combined Figure 1 、 Figure 4 As shown, the threaded connection assembly 3 also includes a lock nut 33, which is assembled at the end of the bolt 31 and is close to the nut 32. The design of the lock nut 33 can effectively improve the connection effect of the threaded connection assembly 3 and prevent the threaded connection assembly 3 from loosening.

[0043] In some embodiments, combined Figure 1 、 Figure 4 As shown, the threaded connection assembly 3 further includes an elastic gasket, which is arranged between the anti-loosening nut 33 and the nut 32. The addition of the elastic gasket can further enhance the anti-loosening effect of the anti-loosening nut 33.

[0044] In some embodiments, combined Figure 3 As shown, the variable-angle wooden structure assembled connection node also includes a positioning sleeve 4, which is integrally formed and sleeved on the outer surface of the second annular column 21. The height of the positioning sleeve 4 is the same as the height of the positioning cone 23. The design of the positioning sleeve 4 can provide a positioning effect during the connection process of the first connecting member 1 and the second connecting member 2, thereby avoiding misalignment of the first connecting member 1 and the second connecting member 2.

[0045] In some embodiments, combined Figures 1 to 4 As shown, the outer end faces of the first connector 1 and the second connector 2 are integrally formed with a connector mounting plate 5, and the connector mounting plate 5 is symmetrically provided with mounting holes. The first connector 1 and the second connector 2 are fixedly connected to the wooden structure through the connector mounting plate 5. The symmetrically provided mounting holes can make the force on the connector mounting plate 5 more uniform.

[0046] Combine Figures 1 to 5As shown, a wooden structure uses the variable-angle wooden structure prefabricated connection node, the wooden structure includes a transverse plate and a longitudinal plate, the transverse plate and the longitudinal plate are both provided with a connector mounting hole, the variable-angle wooden structure prefabricated connection node passes through the connector mounting hole, the variable-angle wooden structure prefabricated connection node is fixedly connected to the transverse plate and the longitudinal plate through a connector mounting plate 5, and the manner in which the variable-angle wooden structure prefabricated connection node is embedded in the wooden structure can effectively avoid the surface protrusion caused by the variable-angle wooden structure prefabricated connection node after installation, which affects the subsequent assembly of the wooden structure.

[0047] In some embodiments, combined Figure 1 As shown, the transverse plate and the longitudinal plate are both provided with a sunken groove 6 at the connector mounting hole, and the connector mounting plate 5 is fixedly connected in the sunken groove 6. Since the outer dimensions of the variable-angle wooden structure assembled connection node are fixed, when facing transverse plates and longitudinal plates with larger thicknesses, the first connector 1 and the second connector 2 will be away from each other and cannot work normally. The position of the mounting surface of the variable-angle wooden structure assembled connection node can be adjusted through the sunken groove 6 to ensure the normal operation of the variable-angle wooden structure assembled connection node.

[0048] In some embodiments, combined Figure 5 As shown, both the transverse plate and the longitudinal plate are provided with a pad 7 at the connector mounting hole, and the connector mounting plate 5 is fixedly connected to the pad 7. Since the outer dimensions of the variable-angle wooden structure assembled connection node are fixed, when facing transverse plates and longitudinal plates with smaller thicknesses, a larger gap will appear between the transverse plate and the longitudinal plate. By adjusting the position of the mounting surface of the variable-angle wooden structure assembled connection node by the pad 7, a close fit between the transverse plate and the longitudinal plate can be ensured.

[0049] The sinking groove 6 and the pad 7 can be used together or separately. When used together, the thickness of the assembly position of the transverse plate and the longitudinal plate is adjusted to the situation where the connection angle between the first connecting member 1 and the second connecting member 2 is 0 through the sinking groove 6. The thickness of a single pad 7 corresponds to the height of a single step on the step surface. The number of pads 7 can be increased appropriately according to usage requirements.

[0050] Working process: The bolt 31 passes through the second connecting member 2, and is then connected or sleeved on the bolt 31 in the order of the nut 32, the first connecting member 1, and the nut 32. The nut 32 is rotated so that the two nuts 32 are tightly against the first connecting member 1. The position of the second connecting member 2 is adjusted by staggering. The angle between the first connecting member 1 and the second connecting member 2 will increase by 10 degrees for each step staggered. When the two spiral rising surfaces are close to each other, the angle between the first connecting member 1 and the second connecting member 2 reaches a predetermined angle. Then, the bolt 31 is tightened to fix the position of the first connecting member 1 and the second connecting member 2.

[0051] When the angle between the first connecting member 1 and the second connecting member 2 is different, the total height after the first connecting member 1 and the second connecting member 2 are connected will also change. The total thickness of the assembly position of the transverse plate and the longitudinal plate can be adjusted by adding a sinking groove 6 or a pad 7. By designing the thickness of the assembly position of the transverse plate and the longitudinal plate in combination with the first connecting member 1 and the second connecting member 2, the angle between the transverse plate and the longitudinal plate can be quickly adjusted to the planned size. Finally, the transverse plate and the longitudinal plate are fixedly connected by the locking force between the bolt 31 and the nut 32.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
