Description

TECHNICAL FIELD

[0001] The present application relates to the field of structural engineering, and in particular to a multi-pin shaft hinged support, a connecting joint and an assembling method of the multi-pin shaft hinged support. BACKGROUND

[0002] Since the traditional pin shaft joint only bears axial force or ear plate in-plane shear force, the engineering use range of the traditional pin shaft joint is limited. With a large number of buildings such as connected buildings and long-span buildings emerging in China, the stress condition at the joint and the joint and its construction technology are becoming more and more complex. Therefore, the problem that the traditional planar single-pin shaft connecting joint can only transmit axial force and ear plate in-plane shear force needs to be solved to broaden the use range of the pin shaft joint in the engineering field. SUMMARY

[0003] The purpose of the present application is to provide a multi-pin shaft hinged support, a connecting joint and an assembling method of the multi-pin shaft hinged support, which aims to solve the problem that the traditional planar single-pin shaft connecting joint can only transmit axial force and ear plate in-plane shear force.

[0004] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0005] In a first aspect, some embodiments of the present application provide a multi-pin shaft hinged support, comprising a plurality of first ear plate nodes, a plurality of second ear plate nodes and at least one pin shaft.

[0006] Each first ear plate node comprises a first back plate and n first ear plates, the n first ear plates are distributed on the same side of the first back plate along a first straight line direction and connected with the first back plate, n is a natural number greater than zero. The first back plates of each first ear plate node are connected in turn along the first straight line direction, and each first ear plate is located on the same side of the first back plate. Each first ear plate is provided with a first through hole along the first straight line direction.

[0007] Each second ear plate node comprises a second back plate and n+1 second ear plates, the n+1 second ear plates are distributed on the same side of the second back plate along the first straight line direction and connected with the second back plate. The second back plates of each second ear plate node are connected in turn along the first straight line direction, and each second ear plate is located on the same side of the second back plate. Each second ear plate is provided with a second through hole along the first straight line direction.

[0008] Each first ear plate in each first ear plate node is inserted between two adjacent second ear plates in the same second ear plate node, and the adjacent first through hole and the second through hole are aligned. The pin shaft is inserted into the first through hole and the second through hole for connecting the first ear plate node and the corresponding second ear plate node.

[0009] Thus, in the process of installing the multi-pin shaft hinged support, the plurality of first lug plate nodes can be close to the plurality of second lug plate nodes, so that each first lug plate in each first lug plate node can be inserted between two adjacent second lug plates in a corresponding same second lug plate node respectively. Then, the adjacent first through holes and the second through holes can be aligned. Finally, the pin shafts are inserted into the first through holes and the second through holes in the left-right direction, so that each first lug plate node and a second lug plate node are connected by the pin shafts.

[0010] In the direction perpendicular to the first back plate, the hinged structure of the pin shaft, the plurality of first lug plate nodes and the plurality of second lug plate nodes can jointly bear the axial tension and compression force of the multi-pin shaft hinged support. In the direction parallel to the first back plate and the first lug plate, the hinged structure of the pin shaft, the plurality of first lug plate nodes and the plurality of second lug plate nodes can jointly bear the lug plate in-plane shear force (i.e. the in-plane shear force of the first lug plate and the second lug plate) of the multi-pin shaft hinged support.

[0011] Compared with the case that the multi-pin shaft hinged support in the related art only includes one hinged first lug plate node and one second lug plate node.

[0012] In the embodiments of the present application, since the multi-pin shaft hinged support can correspondingly install the plurality of first lug plate nodes and the plurality of second lug plate nodes in the first straight line direction, it is equivalent to increasing the bearing size of the first lug plate, the second lug plate and the pin shaft in the first straight line direction in the multi-pin shaft hinged support. It is beneficial to improve the bearing capacity of the multi-pin shaft hinged support to the axial tension and compression force and the lug plate in-plane shear force, and at the same time, it also makes the multi-pin shaft hinged support can bear the out-of-plane bending moment and the torque. That is, the problem that the traditional single-pin shaft connection node in the plane can only transmit the axial force and the lug plate in-plane shear force is solved, so that the multi-pin shaft hinged support provided by the embodiments of the present application can be applied to the field of structural engineering with more complex node stress, which is beneficial to improve the application range of the pin shaft hinged support.

[0013] Optionally, the number of pin shafts is a plurality, and each pin shaft is used for connecting one first lug plate node and a corresponding second lug plate node.

[0014] Optionally, the multi-pin shaft hinged support further includes two first shear webs, and the plurality of second lug plate nodes and the plurality of first lug plate nodes are located between the two first shear webs in the first straight line direction. In the direction perpendicular to the first back plate, two ends of each first shear web are connected with a corresponding first back plate and a corresponding second back plate respectively.

[0015] Optionally, the multi-pin shaft hinged support further includes at least one second shear web, and the second shear web is installed between two adjacent second lug plate nodes in the first straight line direction. In the direction perpendicular to the first back plate, two ends of each second shear web are connected with a corresponding first back plate and a corresponding second back plate respectively.

[0016] Optionally, the number of the second shear webs is one less than the number of the second lug nodes, and one second shear web is installed between any two adjacent second lug nodes.

[0017] Optionally, the first shear web is located on the extension line of the axis of the nearby pin shaft. The second shear web is located on the extension line of the axes of the nearby two pin shafts.

[0018] Optionally, each first lug is perpendicular to the connected first back plate, and each second lug is perpendicular to the connected second back plate. The first back plate is parallel to the second back plate. Each first shear web is perpendicular to the second lug and the second back plate, respectively. Each second shear web is perpendicular to the second lug and the second back plate, respectively.

[0019] Optionally, along the first straight line direction, the sum of the thicknesses of the two second lugs on both sides of each second lug node is greater than or equal to the average thickness of the first lug of each first lug node.

[0020] In the second aspect, some embodiments of the present application provide a connecting node, comprising a first connecting member, a second connecting member, and the multi-pin shaft hinged support in the first aspect. The first connecting member is connected to the side of the plurality of first back plates away from the first lug, and the second connecting member is connected to the side of the plurality of second back plates away from the second lug.

[0021] Since the connecting node provided by the embodiments of the present application comprises the multi-pin shaft hinged support in the first aspect, both can solve the same technical problems and achieve the same technical effects.

[0022] In the third aspect, some embodiments of the present application provide an assembly method of the multi-pin shaft hinged support, for installing the multi-pin shaft hinged support in the first aspect. The assembly method comprises:

[0023] Aligning the first through hole and the second through hole. Along the first straight line direction, inserting each pin shaft into the second through hole and the first through hole from the end of each group of second lug nodes to install each first lug node and the corresponding each second lug node.

[0024] Aligning the first through hole and the second through hole. Along the first straight line direction, inserting each pin shaft into the second through hole and the first through hole from the end of each group of second lug nodes to install each first lug node and the corresponding each second lug node.

[0025] The above two steps are repeated to continue to install each group of first ear plate nodes and each group of second ear plate nodes. The first back plate in each group of first ear plate nodes after connection is connected in sequence along the first linear direction, and two adjacent second back plates are connected in sequence.

[0026] Since the assembly method of the multi-pin shaft hinged support provided by the embodiment of the application is used for installing the multi-pin shaft hinged support in the first aspect, both can solve the same technical problem and achieve the same technical effect. On this basis, by assembling the multi-pin shaft hinged support in sections along the first direction, the plug-in installation of the pin shaft 23 is facilitated.

[0027] Optionally, in the case where the multi-pin shaft hinged support further comprises two first shear webs and a second shear web, the assembly method further comprises:

[0028] Along the first linear direction, the two first shear webs are respectively installed at the two ends of the first back plate. Along the direction perpendicular to the first back plate, the two ends of each first shear web are respectively connected with the first back plate and the second back plate.

[0029] Along the first linear direction, the second shear web is installed between the two adjacent second ear plate nodes. Along the direction perpendicular to the first back plate, the two ends of each second shear web are respectively connected with the first back plate and the second back plate.

Rather, the use of "exemplary" is intended to present the relevant concept in a specific manner.

[0053] In one aspect, as Figure 1 shown, the embodiments of the present application provide a connection node 100, which can include a first connecting piece 1, a multi-pin shaft hinged support 2 and a second connecting piece 3.

[0054] When the first connecting piece 1 and the second connecting piece 3 are connected through the multi-pin shaft hinged support 2. Referring to Figure 1For example, the multi-pin shaft hinged support 2 can include a plurality of first lug nodes 21, a plurality of second lug nodes 22, and at least one pin shaft 23. Each first lug node 21 can include a first back plate 211 and n first lugs 212. If n≥2, the n first lugs 212 can be distributed on the back side of the first back plate 211 in the left-right direction (i.e., the first linear direction) at intervals. If n=1, one first lug 212 of each first lug node 21 can be connected to the middle of the back side of the first back plate 211 and can be approximately perpendicular to the first linear direction. When connecting the first back plate 211 and each first lug 212, the upper end of each first lug 212 can be connected to the back side wall of the first back plate 211, respectively. The connection can be made by welding, or threaded holes can be formed on the first back plate 211 and each first lug 212 from front to back, and the first back plate 211 and each first lug 212 can be connected by screws.

[0055] Continuing to refer to Figure 1 Each second lug node 22 can include a second back plate 221 and n+1 second lugs 222. The n+1 second lugs 222 can be distributed on the front side of the second back plate 221 at intervals in the left-right direction. When connecting the second back plate 221 and each second lug 222, the lower end of each second lug 222 can be connected to the front side wall of the second back plate 221, respectively. The connection can be made by welding, or threaded holes can be formed on the second back plate 221 and each second lug 222 from back to front, and the second back plate 221 and each second lug 222 can be connected by screws.

[0056] As Figure 1As shown, the first back plates 211 of the plurality of first lug nodes 21 can be connected in sequence along the left-right direction. The second back plates 221 of the plurality of second lug nodes 22 can also be connected in sequence along the left-right direction. Exemplarily, the above-mentioned connection manner can be welding connection, or a connecting member can be installed on the front side of the two adjacent first back plates 211 or the rear side of the two adjacent second back plates 221, so as to achieve the connection and installation of the two adjacent first back plates 211 or the two adjacent second back plates 221. In this way, after the plurality of first lug nodes 21 are connected and installed in sequence along the left-right direction, and the plurality of second lug nodes 22 are connected and installed in sequence along the left-right direction, when the plurality of first back plates 211 are arranged opposite to the plurality of second back plates 221, or even parallel to the plurality of second back plates 221, the plurality of first lugs 212 of the plurality of first lug nodes 21 can be located on the rear side of the first back plate 211, and the plurality of second lugs 222 of the plurality of second lug nodes 22 can be located on the front side of the second back plate 221. A first through hole 213 can be formed on each first lug 212 close to the rear end along the left-right direction, and a second through hole 223 can be formed on each second lug 222 close to the front end along the left-right direction.

[0057] In this way, during the installation of the multi-pin shaft hinge support 2, the plurality of first lug nodes 21 can be close to the plurality of second lug nodes 22, so that each first lug 212 in each first lug node 21 can be inserted between the two adjacent second lugs 222 in the corresponding same second lug node 22. Then, the adjacent first through holes 213 and the second through holes 223 can be aligned, and finally the pin shaft 23 is inserted into the first through hole 213 and the second through hole 223 along the left-right direction, so as to connect each first lug node 21 and a second lug node 22 through the pin shaft 23.

[0058] In this way, as shown, Figure 1 the first connecting member 1 can be connected to the front side of the plurality of first back plates 211, and the second connecting member 3 can be connected to the rear side of the plurality of second back plates 221.

[0059] For example, the first connector 1 can be a metal structure with a large span in the front-to-back direction, and it can also have a large width in the left-to-right direction. Thus, the first connector 1 can be directly fixed to the first back plate 211 by welding or using nuts. The second connector 3 can be a steel structure support beam, load-bearing column, or truss, etc. Thus, the second connector 3 can be welded to the second back plate 221, or it can be fixed to the second back plate 221 using multiple nuts. Alternatively, the second connector 3 can also be a reinforced concrete support beam, load-bearing column, or load-bearing wall, etc., which can also achieve a fixed connection with the second back plate 221. Furthermore, in some other embodiments, the positions of the first connector 1 and the second connector 3 can be interchanged, meaning the first connector 1 can be connected to the second back plate 221, and the second connector 3 can be connected to the first back plate 211.

[0060] Therefore, when connecting the first connector 1 and the second connector 3 via the multi-pin hinge support 2, the first back plate 211 of the multiple first ear plate nodes 21, after being connected and installed with the first connector 1, can be considered as part of the first connector 1. Similarly, the second back plate 221 of the multiple second ear plate nodes 22, after being connected and installed with the second connector 3, can be considered as part of the second connector 3. Therefore, the first connector 1 and the second connector 3 can be hinged together via the multi-pin hinge support 2. At this connection node 100, since the force between the first connector 1 and the second connector 3 is concentrated at the multi-pin hinge support 2, and each first ear plate 212 and each second ear plate 222 can be installed approximately parallel to the vertical direction.

[0061] Thus, as Figure 1 As shown, in the front-to-back direction, the hinge structure of the pin 23, multiple first ear plate nodes 21, and multiple second ear plate nodes 22 can effectively share the tensile and compressive axial forces of the multi-pin hinge support 2. Figure 2As shown, in the vertical direction, the hinged structure of the pin 23, multiple first ear plate nodes 21, and multiple second ear plate nodes 22 can effectively share the in-plane shear force of the ear plates (i.e., the in-plane shear force of the first ear plate 212 and the second ear plate 222) of the multi-pin hinged support 2. In this embodiment, since the multi-pin hinged support 2 can install multiple first ear plate nodes 21 and multiple second ear plate nodes 22 one-to-one in the left-right direction, it is equivalent to increasing the bearing capacity of the first ear plate nodes 21, second ear plate nodes 22, and pin 23 in the left-right direction. This is beneficial to improving the bearing capacity of the multi-pin hinged support 2 for tensile and compressive axial forces and in-plane shear forces of the ear plates, and also enables the multi-pin hinged support 2 to bear out-of-plane bending moments and torques. That is, it solves the problem that traditional single-pin connection nodes in a plane can only transmit axial force and shear force in the ear plate, so that the multi-pin hinge support 2 provided in this application embodiment can be applied to structural engineering fields with more complex node forces, which is conducive to improving the application range of pin hinge support.

[0062] It should be noted that, along the left-right direction, the closer the multi-pin hinged support 2 is to both ends, the greater the out-of-plane bending moment and torque acting at that location can be. For example... Figure 2 As shown, in actual use, the vertical direction of the multi-pin hinge support 2 is parallel to the vertical direction during actual use. At this time, the in-plane shear force of the ear plate can be regarded as the in-plane vertical shear force.

[0063] For example, such as Figure 1 As shown, the out-of-plane bending moment can lie in a plane parallel to the front-back and left-right directions. When the out-of-plane bending moment applied by the first connector 1 acts on multiple first ear plate nodes 21, the force exerted by the out-of-plane bending moment on the rightmost first ear plate node 21 can be equivalent to a rearward tensile-compressive axial force, and the corresponding force exerted by the out-of-plane bending moment on the leftmost first ear plate node 21 can be equivalent to a forward tensile-compressive axial force. Therefore, in order to achieve force balance, the second connector 3 can apply a reverse out-of-plane bending moment to the multiple second ear plate nodes 22 to balance the aforementioned forces.

[0064] like Figure 2 As shown, the torque can be parallel to the first back plate 211 or the second back plate 221, when the first connector 1 (such as...) Figure 1 When the applied torque (as shown) acts on multiple first lug nodes 21, the force of the torque on the rightmost first lug node 21 can be equivalent to an upward in-plane shear force, and the corresponding force of the torque on the leftmost first lug node 21 can be equivalent to a downward tensile-compressive axial force. Therefore, in order to balance the forces, the second connector 3 can apply a reverse torque to the multiple second lug nodes 22 to balance the above forces.

[0065] The multi-pin shaft hinged support 2 can be made of metal materials, such as steel, aluminum alloy, titanium alloy, and the like. In addition, the multi-pin shaft hinged support 2 can also be made of high polymer composite materials with high structural strength and certain ductility, such as high-strength plastic. This is not limited.

[0066] In the case where the multi-pin shaft hinged support 2 is made of metal materials, for each first lug node 21 and each second lug node 22, an integrated structure can also be made by a casting process. Alternatively, in the case where there is enough space, the first lug 212 and the second lug 222 can be respectively provided in a T-shaped structure, and the first lug 212 and the first back plate 211 are connected by screws, and the second lug 222 and the second back plate 221 are connected by screws.

[0067] It should be noted that in the multi-pin shaft hinged support 2, the number of first lug nodes 21 is the same as the number of second lug nodes 22. For example, the number of first lug nodes 21 and the number of second lug nodes 22 can also be five. Alternatively, the number of first lug nodes 21 and the number of second lug nodes 22 can also be four. Alternatively, the number of first lug nodes 21 and the number of second lug nodes 22 can also be two, three, six or even more. That is, the number of first lug nodes 21 and the number of second lug nodes 22 can be a natural number greater than one, which is not limited herein.

[0068] In addition, for the number of first lugs 212 and the number of second lugs 222. As shown in Figure 1 each first lug node 21 can include two first lugs 212, and each second lug node 22 can include three second lugs 222. Alternatively, as shown in Figure 2 each first lug node 21 can also include three first lugs 212, and each second lug node 22 can include four second lugs 222. That is, in the embodiment of the present application, the number of first lugs 212 in each first lug node 21 can be n, and the number of second lugs 222 in each second lug node 22 can be n+1, and n is a natural number greater than zero.

[0069] In some embodiments, the multi-pin shaft hinged support 2 can include a plurality of pin shafts 23, and the number of pin shafts 23 can be the same as the number of first lug nodes 21. Correspondingly, each pin shaft 23 is used to connect one first lug node 21 and a corresponding second lug node 22. That is, the pin shaft 23 is sequentially inserted into the second through hole 223 and the first through hole 213 alternately distributed in the left-right direction, so as to assemble the multi-pin shaft hinged support 2.

[0070] Since the force is mutual, the first ear node 21 and the second ear node 22 connected to the same pin shaft 23 are subjected to the opposite direction of the axial force in the front-back direction, and the size is equal. Since the number of the second ear 222 connected to the same pin shaft 23 is one more than the number of the first ear 212. Therefore, the sum of the thickness (left-right direction) of the two second ears 222 on the left and right sides of the second ear node 22 can be set as a, and the average thickness of each first ear 212 in the first ear node 21 is b. It can be set that a=b, so that in the left-right direction, the sum of the thickness of the first ear 212 connected to the same pin shaft 23 is equal to the sum of the thickness of the second ear 222. When the materials of the first ear 212 and the second ear 222 are the same, the size of the load force of the first ear 212 and the second ear 222 is generally equal, which is beneficial to save materials.

[0071] In some embodiments, the thickness of each first ear 212 can be equal. And in each second ear node 22, the thickness of the two second ears 222 on the left and right sides can be half of the thickness of the first ear 212, and the thickness of the remaining second ears 222 can be equal to the thickness of the first ear 212. In this way, the structural difference between the first ear 212 and the second ear 222 can be reduced, which is convenient for producing and installing the multi-pin shaft hinged support 2. At the same time, the distance between the adjacent two first ears 212 can also be adjusted to be equal to the distance between the adjacent two second ears 222, which is beneficial to keep the overall force balance of the multi-pin shaft hinged support 2.

[0072] In some embodiments, as shown in Figure 3 The multi-pin shaft hinged support 2 can also include two first shear webs 24 and at least one second shear web 25. For example, the two first shear webs 24 can be respectively located at the left and right ends of the second back plate 221, and the front and rear ends of each first shear web 24 are respectively connected with the rear side wall of the first back plate 211 and the front side wall of the second back plate 221. In the left-right direction, all the first ear nodes 21 (as shown in Figure 1 The second ear nodes 22 are located between the two first shear webs 24. The number of the second shear web 25 can be one less than the number of the second ear node 22, and in the left-right direction, each second shear web 25 can be installed between the adjacent two second ear nodes 22, and the front and rear ends of each second shear web 25 are respectively connected with the rear side wall of the first back plate 211 and the front side wall of the second back plate 221.

[0073] Thus, the first back plate 211 and the second back plate 221 can be further connected in the front-rear direction by the first shear web 24 and the second shear web 25. By the arrangement of the first shear web 24 and the second shear web 25, the multi-pin shaft hinged support 2 can balance the ear plate out-of-plane shear force (relative to the first ear plate 212 and the second ear plate 222) to avoid the ear plate out-of-plane shear force in the left-right direction to destroy the stress structure of the multi-pin shaft hinged support 2 (such as bending the first ear plate 212 and the second ear plate 222 in the left-right direction), breaking the limitation that the pin shaft connection structure cannot bear the ear plate out-of-plane shear force. In addition, the tension-compression shaft force between the multi-pin shaft hinged supports 2 can also be transmitted and shared by the first shear web 24 and the second shear web 25. For the two first shear webs 24 at the left and right ends, when the multi-pin shaft hinged support 2 bears the out-of-plane bending moment, the two first shear webs 24 at the left and right ends of the multi-pin shaft hinged support 2 can also share part or even all of the out-of-plane bending moment load.

[0074] For example, when the first shear web 24 and the second shear web 25 are installed, the front and rear ends of the first shear web 24 and the front and rear ends of the second shear web 25 can be fixedly connected by welding. Since the first shear web 24 and the second shear web 25 can be metal plates such as steel plates, they have high structural strength. Therefore, the thickness of the first shear web 24 and the second shear web 25 connected between the first back plate 211 and the second back plate 221 in the up-down direction can be set to be thinner, which can reduce the adverse effect on the hinged rotation between the first ear plate joint 21 and the second ear plate joint 22 while meeting the requirement of bearing the ear plate out-of-plane shear force.

[0075] It should be noted that two first shear webs 24 and multiple second shear webs 25 can be simultaneously installed between the first back plate 211 and the second back plate 221. In addition, only the first shear web 24 or the second shear web 25 can be installed between the first back plate 211 and the second back plate 221. This is not limited.

[0076] In addition, only the second shear web 25 can be installed between the first back plate 211 and the second back plate 221. The number of the second shear web 25 can be one, two, three or more, which is generally one less than the number of the second ear plate joint 22. Between the first back plate 211 and the second back plate 221 and in the left-right direction: one second shear web 25 can be installed between any two adjacent second ear plate joints 22; or the number of the second shear web 25 is two, and the two second shear webs 25 can be installed in adjacent two gaps or in two gaps arranged at intervals between any two second ear plate joints 22, which is not limited.

[0077] In some embodiments, in the case of installing two first shear webs 24 in the multi-pin hinge support 2, as shown in Figure 4 and Figure 5 each first shear web 24 can be located on the extension line of the axis of the adjacent pin 23. Correspondingly, each second shear web 25 can also be located on the extension line of the axis of the adjacent two pins 23.

[0078] Continuing to refer to Figure 3 and Figure 4 , when installing the multi-pin hinge support 2, the first back plate 211 and the second back plate 221 are generally spaced and parallel. In addition, the plurality of first ear plates 212 are parallel to each other, and the plurality of second ear plates 222 are parallel to each other. After being hingedly installed by the pin 23, each second ear plate 222 can also be parallel to each first ear plate 212. In combination with Figure 5 , for the first shear web 24 and the second shear web 25, the first shear web 24 and the second shear web 25 can be located in the same horizontal plane. Among them, the first shear web 24 can be perpendicular to the second back plate 221 and the second ear plate 222 at the same time, and the second shear web 25 can be perpendicular to the second back plate 221 and the second ear plate 222 at the same time. As shown in Figure 4 , the first shear web 24 is located in the middle of the first back plate 211 and the second back plate 221 in the up-down direction, and coincides with the extension line of the axis of the pin 23. Thus, the first shear web 24 and the second shear web 25 avoid adversely affecting the hinged rotation between the first ear plate node 21 and the second ear plate node 22.

[0079] Exemplarily, after the multi-pin hinge support 2 is installed, the first back plate 211 and the second back plate 221 can be perpendicular to the front-back direction at the same time. The first ear plate 212 and the second ear plate 222 can be perpendicular to the left-right direction at the same time. The axes of the plurality of pins 23 are collinear and parallel to the left-right direction. The first shear web 24 and the second shear web 25 can be perpendicular to the up-down direction at the same time, and the first shear web 24 and the second shear web 25 are coplanar. In this way, between the first back plate 211 and the second back plate 221, the first shear web 24, the second shear web 25, and the pin 23 as the main body of the axial force transmission are approximately uniformly distributed in the left-right direction, and the force is balanced.

[0080] In some embodiments, as shown in Figure 4 and Figure 5As shown, the first ear plate 212 and the second ear plate 222 are hingedly installed through the pin shaft 23. In order to make the installation adjustment process of the first ear plate 212 and the second ear plate 222 in the plug-in alignment more convenient, the rear end of the first ear plate 212 can be provided as a circular arc structure protruding forward, and the center of the circular arc structure is close to the first back plate 211. Correspondingly, the front end of the second ear plate 222 is provided as a circular arc structure protruding backward, that is, the center of the circular arc structure is close to the second back plate 221. In addition, the first ear plate 212 and the second ear plate 222 can also be provided as a circular arc structure arranged opposite to each other, and the straight edges are respectively connected and installed with the first back plate 211 and the second back plate 221.

[0081] In this way, when installing the multi-pin shaft hinged support 2, after the first ear plate 212 is inserted between the two adjacent second ear plates 222, in the process of aligning the first through hole 213 and the second through hole 223, since the rear end of the first ear plate 212 and the front end of the second ear plate 222 are both circular arc structures, that is, there is no sharp end, the rear side sharp end of the first ear plate 212 and the front side sharp end of the second ear plate 222 can be avoided from being in contact with the second back plate 221 and the first back plate 211 respectively, so as to facilitate the alignment adjustment of the first through hole 213 and the second through hole 223. After being hingedly installed through the pin shaft 23, since the first ear plate 212 can rotate around the circumference of the pin shaft 23 relative to the second ear plate 222, the rear side sharp end of the first ear plate 212 and the front side sharp end of the second ear plate 222 can also be avoided from being in contact with the second back plate 221 and the first back plate 211 respectively, that is, to facilitate the relative rotation between the first ear plate 212 and the second ear plate 222 which are plugged on the pin shaft 23.

[0082] Referring to Figure 5 , the inner diameter of the first through hole 213 and the inner diameter of the second through hole 223 can be the same or different, as long as the pin shaft 23 can be inserted. For example, the inner diameter of the first through hole 213 can be equal to the inner diameter of the second through hole 223, and both are slightly larger than the outer diameter of the pin shaft 23 or can be equal to the outer diameter of the pin shaft 23 at the same time. While facilitating the plug-in installation of the pin shaft 23 with each first through hole 213 and each second through hole 223, a larger contact area between the pin shaft and the inner wall of each first through hole 213 and each second through hole 223 can also be achieved, thereby avoiding the uneven stress between the pin shaft 23 and the first ear plate 212 and the second ear plate 222.

[0083] On the other hand, the embodiment of the present application also provides a multi-pin shaft hinged support assembly method for installing the multi-pin shaft hingedly supported 2 in the above aspect, as shown in the figure, Figure 6 The assembly method comprises:

[0084] Step S100: Insert each first ear node into a second ear node, and insert each first ear into two adjacent second ears of the same second ear node. Each first ear node is a group of at most two first ear nodes, and the number of first ear nodes in each group of first ear nodes is equal to the number of second ear nodes in the corresponding group of second ear nodes.

[0085] It should be noted that in step S100, the multi-pin shaft hinge support 2 is generally configured as a module of multiple groups of first ear nodes 21, multiple groups of second ear nodes 22 and multiple pin shafts 23. Each group of first ear nodes 21 can include one first ear node 21 or two first ear nodes 21 connected in the left-right direction. Each group of second ear nodes 22 can include one second ear node 22 or two second ear nodes 22 connected in the left-right direction. In addition, the number of first ear nodes 21 in a corresponding group of first ear nodes 21 is equal to the number of second ear nodes 22 in a corresponding group of second ear nodes 22, so as to facilitate the insertion of the first ear nodes 21 into the corresponding second ear nodes 22.

[0086] Step S200: Align the adjacent first and second through holes. In the first linear direction, insert each pin shaft from the end of each group of second ear nodes into the second and first through holes to connect each first ear node and each corresponding second ear node.

[0087] The position of each group of first ear nodes 21 or each group of second ear nodes 22 can be adjusted, such as adjusting the relative position of the first ear nodes 21 in the front-back direction and the up-down direction with respect to the second ear nodes 22, so as to align the adjacent first and second through holes 213 and 223, thereby facilitating the insertion and installation of the pin shaft 23.

[0088] Subsequently, when the number of first ear nodes 21 and second ear nodes 22 is one respectively, a pin shaft 23 can be inserted into the second and first through holes 223 and 213 from either end of the second ear nodes 22 in the first linear direction (i.e. the left-right direction). If the number of first ear nodes 21 and second ear nodes 22 is two respectively, two pin shafts 23 can be inserted into the corresponding second and first through holes 223 and 213 from the two ends of the two second ear nodes 22 in the first linear direction, and one pin shaft 23 can connect one first ear node 21 and one second ear node 22.

[0089] Step S300: Repeat step S100 and step S200 to continue installing other each group of first ear plate nodes and each group of second ear plate nodes. The first back plate in each group of first ear plate nodes after connection is connected in turn along the first linear direction, and the adjacent second back plate is connected.

[0090] Repeat step S100 and step S200 to install each group of first ear plate nodes 21 and the corresponding group of second ear plate nodes 22 through the pin shaft. Then the first back plate 211 in each group of first ear plate nodes 21 after connection can be connected in turn along the first linear direction. And each second back plate 221 is connected in turn to complete the assembly of the multi-pin hinge support 2.

[0091] It should be noted that in the process of assembling the multi-pin hinge support through the above-mentioned multi-pin hinge support assembly method, if the first connecting piece 1 and the second connecting piece 3 are connected through the multi-pin hinge support 2, exemplary, after step S300, the first connecting piece 1 and the second connecting piece 3 can be installed between the multi-pin hinge supports 2 after assembly.

[0092] In addition, after step S200, the first back plate 211 of the first ear plate node 21 after connection and the first connecting piece 1 can be connected, and the second back plate 221 of the second ear plate node 22 after connection and the second connecting piece 3 can be connected. Then repeat step S100 and step S200 in turn to continue installing other each group of first ear plate nodes 21 and each group of second ear plate nodes 22. Then, the first back plate 211 in each group of first ear plate nodes 21 after connection can be connected with the first connecting piece 1 and the last first back plate 211 along the first linear direction, and the two adjacent second back plates 221 can be connected in turn, and the plurality of second back plates 221 can be connected with the second connecting piece 3.

[0093] In this way, through the segmented installation of the multi-pin hinge support 2, the pin shaft 23 can be easily positioned and installed. And since the multi-pin hinge support assembly method provided by the application is used to assemble the multi-pin hinge support in the upper garment, the same technical effects can be achieved, and the same technical problems can be solved, which will not be described here.

[0094] In addition, after step S300, if the multi-pin hinge support further comprises a first shear web and a second shear web, the multi-pin hinge support assembly method can further comprise:

[0095] S410: Along the first linear direction, install two first shear webs at both ends of the first back plate respectively. Along the direction perpendicular to the first back plate, connect both ends of each first shear web with the first back plate and the second back plate respectively.

[0096] S420: install the second shear web between the two adjacent second lug nodes along the first straight line direction. Connect the two ends of each second shear web with the first back plate and the second back plate respectively along the direction perpendicular to the first back plate.

[0097] Wherein, the order of step S410 and step S420 can be exchanged, or only step S410 can be executed, or only step S420 can be executed, as long as the connection and installation of the first shear web 24 and / or the second shear web 25 can be completed. In addition, after the multi-pin shaft hinge support 2 is connected and installed with the first connecting piece 1 and the second connecting piece 3 respectively, steps S410 and / or S420 can be executed, which is not limited.

[0098] In the description of the present specification, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0099] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope described in the claims.
