Description

Technical Field

[0001] This application relates to the field of building structure connection technology, and in particular to a tie rod connection node and a tie rod suspension building system. Background Technology

[0002] Due to their advantages of high strength and small cross-section, steel tie rods are increasingly used as members to bear gravity loads. When steel tie rods are arranged vertically as members to bear gravity loads, adjacent vertical steel tie rods need to be connected to the transverse steel beams at the steel beams.

[0003] Traditional steel tie rod nodes are segmented fork-ear connections. This type of node requires the ear plate to be welded to the steel beam. There are no special requirements for the steel beam, but the ear plate anchors are generally large. The hinge structure at the ear plate is completely exposed to the outside of the beam. The exposed ear plate is susceptible to impact or corrosion, and the exposed hinge structure at the ear plate also affects the aesthetics of the steel structure building. Summary of the Invention

[0004] The purpose of this application is to provide a tie rod connection node and a tie rod suspension building system, which aims to solve the problem of exposed hinge structure at the end of the tie rod.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] On one hand, some embodiments of this application provide a tie rod connection node, including a connecting beam, a hinge assembly, a pin, and at least one tie rod. The connecting beam extends along a first straight direction and has a mounting cavity. The mounting cavity has an opening on at least one side along a second straight direction, the first and second straight directions intersecting. The hinge assembly is at least partially located within the mounting cavity, and the portion of the hinge assembly within the mounting cavity has a first through hole facing the side wall of the mounting cavity. Along a third straight direction, the pin is inserted into the first through hole, and both ends of the pin are connected to the connecting beam at two side walls of the mounting cavity, so that the hinge assembly is hingedly mounted to the connecting beam. The third straight direction is perpendicular to the first and second straight directions. Along the second straight direction, at the opening of the mounting cavity, at least one end of the hinge assembly is connected to a tie rod.

[0007] Thus, taking the second straight line direction as vertical as an example, the upper end of the upper tie rod can be connected to the upper crossbeam (or connecting beam) so that the upper crossbeam can bear the force at the connection node of the tie rod. Correspondingly, the lower end of the lower tie rod can be connected to the lower crossbeam (or connecting beam) to bear the force of the lower crossbeam. Since the hinge assembly is hinged to the connecting beam via a pin, the tie rod connected to the connecting beam via the hinge assembly can bear a large force. Because the hinge part of the hinge assembly is hidden inside the mounting cavity of the connecting beam, it avoids the situation where the protruding and exposed hinge structure is easily damaged by impact or corrosion. At the same time, the overall aesthetics of the steel structure building can be improved by reducing the exposed hinge structure.

[0008] In some embodiments, the hinge assembly includes a hinge member and a bearing member. The hinge member is at least partially located within a mounting cavity, and the portion of the hinge member located within the mounting cavity has a first through hole. The bearing member is mounted within the first through hole, and a pin is inserted into the first through hole along a third linear direction via the bearing member.

[0009] In some embodiments, the bearing component is a spherical plain bearing, including an outer ring and an inner ring, with the outer ring installed in a first through hole. The outer ring is fitted over the outer side of the inner ring, allowing the outer spherical surface of the inner ring and the inner spherical surface of the outer ring to slide together. The inner ring has a second through hole along a third straight direction, and a pin is inserted into the second through hole along the third straight direction and hinged to a hinge member to increase the angle adjustment range of the hinge member relative to the connecting beam.

[0010] In some embodiments, the hinge assembly further includes a plurality of first positioning rings located within the mounting cavity. Along the axial direction of the first through hole, the first positioning rings are distributed on opposite sides of the hinge and connected to the hinge. The inner diameter of the first positioning ring is smaller than the outer diameter of the outer ring and greater than or equal to the inner diameter of the second through hole, to position the outer ring within the first through hole.

[0011] In some embodiments, the hinge assembly further includes at least one second locating ring mounted within the first through-hole. The inner diameter of the second locating ring is smaller than the inner diameter of the outer ring, and the outer diameter of the second locating ring is larger than the inner diameter of the first locating ring. Along the axial direction of the first through-hole, the second locating ring is positioned between the outer ring and the first locating rings, such that the outer ring is press-fitted between the plurality of first locating rings.

[0012] In some embodiments, the connecting beam includes a first connecting segment, a second connecting segment, and a hinge frame. Along a first straight line, a first end of the hinge frame is connected to the first connecting segment, and a second end of the hinge frame is connected to the second connecting segment. The hinge frame has a mounting cavity along a second straight line. Along a third straight line, the hinge frame has two aligned hinge holes corresponding to a pin, with both ends of the pin corresponding to the two hinge holes, and one end of the pin inserted into one of the hinge holes and connected to the hinge frame.

[0013] In some embodiments, the hinge frame includes a first bent segment and a second bent segment. Along a first straight direction, a first end of the first bent segment, a first end of the second bent segment, and a first connecting segment are connected, and a second end of the second bent segment, a second end of the first bent segment, and a second connecting segment are connected. The first and second bent segments are arranged along a third straight direction, and at least one of the first and second bent segments is bent away from the other to form a mounting cavity. The first and second bent segments are sequentially provided with hinge holes along the third straight direction.

[0014] In some embodiments, at least one of the first bend and the second bend is an arc-shaped structure extending along a first straight line direction.

[0015] In some embodiments, at least one of the first and second bending segments is a multi-segment bending structure with an included angle of acute, right, or obtuse.

[0016] In some embodiments, within a cross-section perpendicular to the vertical direction, the hinge frame is a circular ring, an elliptical ring, or a polygonal frame, with the polygonal frame including a triangular frame, a square frame, a rectangular frame, a pentagonal frame, a hexagonal frame, and an octagonal frame.

[0017] In some embodiments, the connecting beam further includes two sleeves, which are at least partially located in the mounting cavity and are respectively disposed in correspondence with the two hinge holes. One sleeve is aligned with a hinge hole along a third straight line and is fixedly connected to the hinge frame for inserting and mounting pins.

[0018] In some embodiments, the connecting beam further includes multiple ribs, and each sleeve is connected to the hinge frame via at least one rib to improve the connection stiffness and strength between the sleeve and the hinge frame.

[0019] In some embodiments, the tie rod connection node further includes multiple limiting members, with a pin located between the multiple limiting members along a third linear direction, one end of the pin being connected to at least one limiting member, and a hinge hole located between the multiple limiting members to prevent the pin from disengaging from the hinge frame along the third linear direction.

[0020] In some embodiments, the mounting cavity has a through-hole structure arranged along a second straight line. There are two tie rods, located on opposite sides of the connecting beam along the extension direction of the hinge assembly. One tie rod is connected to a first end of the hinge assembly, and the other tie rod is connected to a second end of the hinge assembly.

[0021] In some embodiments, the connecting beam is composed of at least one profile, the cross-sectional shape of which includes I-shaped, H-shaped, rectangular, channel-shaped and U-shaped.

[0022] In some embodiments, at least at the mounting cavity, the two profiles are spaced apart in a third linear direction and form a connecting beam including the mounting cavity.

[0023] In some embodiments, when the cross-sectional shape of the profiles constituting the connecting beam is rectangular, the connecting beam is provided with through holes or blind holes in the vertical direction to form a connecting beam including a mounting cavity.

[0024] On the other hand, embodiments of this application also provide a tie-rod suspended building system, including at least one tie-rod connection node as described above and multiple floor frames. At least two adjacent floor frames are suspended and connected by the tie-rod connection node along a second straight direction.

[0025] Since the tie-rod suspension building system provided in this application includes the tie-rod connection node mentioned above, both can solve the same technical problem and achieve the same technical effect. Attached Figure Description

[0052] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0053] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0054] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0055] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, when describing pipelines or channels, the terms "connection" and "linking" used in this application have the meaning of establishing electrical conductivity. The specific meaning needs to be understood in conjunction with the context.

[0056] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0057] Compared to traditional concrete buildings, steel structure buildings use metal materials such as steel plates or profiles instead of reinforced concrete. This results in higher strength and better earthquake resistance. Because steel plate and profile components can be prefabricated in factories and installed on-site, construction time can be reduced. Furthermore, the reusability of metal materials reduces construction waste, making them more environmentally friendly, and thus they are widely used in both industrial and residential buildings.

[0058] In recent years, tie-rod suspension systems have increasingly become the mainstream steel structure system in complex buildings. In this system, high-strength tie rods are used to suspend and support adjacent steel structures in the vertical direction, allowing the steel structure system to serve as the main supporting structure of the building with a large span or high structural strength. Thus, the connection between adjacent steel structures and the tie rods constitutes a suspension structure system.

[0059] For example, in a tie rod suspension system, the upper and lower ends of the tie rod can be connected to the beams in adjacent floors via a hinged structure, such as a segmented plug-in lug connection. Alternatively, the tie rod can be designed as an integral structure extending vertically (connected via sleeves), with its lower end supported by a base or similar structure. As the tie rod extends upwards, it can be fixedly connected to the main load-bearing structure (i.e., beams) of a multi-story building, used for supporting multi-story beams in steel structure buildings, i.e., an integral lower support connection installation method.

[0060] In relevant technical solutions, such as Figure 1 As shown, Figure 1This is a schematic diagram of a connection structure for a tie rod node in a related technical solution. For example, two ear plates 02 can be welded and installed on the upper and lower sides of the crossbeam 01, respectively. The two tie rods 03 on the upper and lower sides of the crossbeam 01 can have insertion slots 04 at their ends near the ear plates 02 for inserting and accommodating the ear plates 02. Subsequently, a hinge shaft 05 can be used to pass through the side wall of the insertion slot 04 and the ear plate 02, so that this end of the tie rod 03 is hinged to the ear plate 02, thereby achieving a segmented insertion-fork ear-joint arrangement for installing the tie rod 03.

[0061] However, since the tie rod 03 and the crossbeam 01 are hinged together via the upper and lower ear plates 02, the connection between the crossbeam 01 and the tie rod 03 is a one-way hinge, which cannot completely release all the constraints at the tie rod node. The hinge structure at the ear plate 02 is fully exposed on the upper and lower sides of the crossbeam 01, which is not conducive to the stability of the hinge structure, and the exposed hinge structure also affects the aesthetics of the steel structure building.

[0062] On the one hand, this application provides a tie rod connection node 100 to solve the above problems, such as Figure 2 As shown, Figure 2 This is a three-dimensional structural diagram of a tie rod connection node 100 provided in an embodiment of this application. The tie rod connection node 100 may include a connecting beam 10, a hinge assembly 20, a pin 30, and two tie rods 40. For example, taking the extension direction of the connecting beam 10 as a first straight line direction, this first straight line direction can be approximately parallel to the horizontal direction, can be a left-right direction, can be a front-back direction, and can also have an angle with or without a front-back direction; it is not limited in this respect. Taking the first straight line direction as... Figure 2 Taking the left-right direction as an example, the connecting beam 10 can be provided with a through-hole structure mounting cavity 11 along the second straight direction (such as the up-down direction) for mounting the hinge assembly 20. The first straight direction and the second straight direction can be perpendicular to each other or intersecting; this is not limited.

[0063] Continue to refer to Figure 2 At least a portion of the structure of the hinge assembly 20 may be located within the mounting cavity 11. For example... Figure 3 As shown, Figure 3 for Figure 2The diagram shows a connection structure of the hinge assembly 20 and the pin 30. The hinge assembly 20, located on the side wall of the mounting cavity 11 facing the mounting cavity 11, may have a first through hole 21. Correspondingly, the installation position and angle of the hinge assembly 20 can be adjusted so that the axis of the first through hole 21 is approximately parallel to a third straight line direction, which can be perpendicular to the first and second straight line directions. For example, the third straight line direction can be a front-back direction. Similarly, the axis of the pin 30 can also be approximately parallel to the third straight line direction, and the pin 30 can be inserted into the first through hole 21 along the third straight line direction. Simultaneously, the axial ends of the pin 30 can be connected to two corresponding side walls of the mounting cavity 11 (i.e., connecting beams at the side walls), allowing the hinge assembly 20 to be hinged to the connecting beam 10 via the pin 30. Based on this, the main body of the hinge assembly 20 can extend approximately vertically during installation, and the two tie rods 40 can be distributed on the upper and lower sides of the connecting beam 10 along the extension direction of the hinge assembly 20. The lower end of one of the upper pull rods 40 can be connected to the first end (i.e., the upper end) of the hinge assembly 20, and the upper end of one of the lower pull rods 40 can be connected to the second end (i.e., the lower end) of the hinge assembly 20.

[0064] Thus, the upper end of the upper tie rod 40 can be connected to the upper crossbeam (or connecting beam) so that the upper crossbeam can bear the force at the tie rod connection node 100. Correspondingly, the lower end of the lower tie rod 40 can be connected to the lower crossbeam (or connecting beam) to bear the force of the lower crossbeam. Since the hinge assembly 20 is hinged to the connecting beam 10 via the pin 30, the tie rod 40 connected to the connecting beam 10 via the hinge assembly 20 can bear a large force, which is beneficial to improving the overall stability of the steel structure building. Since the hinge part of the hinge assembly 20 is hidden in the mounting cavity 11 of the connecting beam 10, the situation where the protruding and exposed hinge structure is easily damaged or corroded is avoided. At the same time, the overall aesthetics of the steel structure building can be improved by reducing the exposed hinge structure.

[0065] like Figure 4 As shown, Figure 4 for Figure 2The diagram shows a three-dimensional structural representation of the connecting beam 10. The connecting beam 10 may include a first connecting segment 12, a second connecting segment 13, and a hinge frame 14. The first connecting segment 12, the hinge frame 14, and the second connecting segment 13 can be connected sequentially from left to right; that is, the left end (i.e., the first end) of the hinge frame 14 can be connected to the first connecting segment 12, and the right end (i.e., the second end) of the hinge frame 14 can be connected to the second connecting segment 13. The connecting beam 10 can be a one-piece molded structure or fixedly connected by welding or other processes, possessing high structural strength. The hinge frame 14 may have a mounting cavity 11 along the vertical direction for accommodating and hingedly mounting the hinge assembly 20. To facilitate the insertion and installation of the pin 30, two aligned hinge holes 15 can be provided on the two oppositely arranged side walls of the hinge frame 14 along the third straight line direction (such as the front-back direction) corresponding to the pin 30, so that both ends of the pin 30 can be inserted into the two hinge holes 15 one-to-one, that is, one end of the pin 30 can be inserted into a hinge hole 15 and connected and installed with the hinge frame 14.

[0066] For example, the front end of the pin 30 can be inserted into a hinge hole 15 on the front side, and the rear end of the pin 30 can be inserted into a hinge hole 15 on the rear side. During the installation of the hinge assembly 20 and the pin 30, a portion of the structure of the hinge assembly 20 can be inserted into the mounting cavity 11 first, and the first through hole 21 can be aligned with the two hinge holes 15 in the front-to-back direction. Then, the pin 30 can be inserted into a hinge hole 15, a first through hole 21, and a hinge hole 15 sequentially from front to back (or from back to front), so that the hinge assembly 20 is hinged to the hinge frame 14 through the pin 30, thereby restricting the degree of freedom of the hinge assembly 20 in the up-down and left-to-right directions.

[0067] It should be noted that, in the above embodiments, as Figure 4 As shown, the mounting cavity 11 can be a through-hole structure with openings on both the top and bottom sides. Combined with... Figure 2 At this time, the tie rod 40 on the upper side of the tie rod connection node 100 can be connected to the upper steel structure (such as the upper hinge assembly) so that the tie rod 40 can bear the force of the steel structure at this level through the aforementioned steel structure. Correspondingly, the tie rod 40 on the lower side of the tie rod connection node 100 can be connected to the lower steel structure so that the tie rod connection node 100 can bear the force of the lower steel structure through the lower tie rod 40.

[0068] In some other embodiments, the same tie rod connection node 100 can be used at the uppermost steel structure. In this case, the tie rod connection node 100 may include a tie rod 40 located on the lower side, the upper end of which can be connected to the lower end of the hinge assembly 20, and the lower end of which can be connected to the upper end of the hinge assembly 20 in another tie rod connection node 100 on the lower level.

[0069] Alternatively, the same tie rod connection node 100 can be used at the lowest level of the steel structure building. In this case, the tie rod connection node 100 may include a tie rod 40 located on the upper side, the lower end of which can be connected to the upper end of the hinge assembly 20, and the upper end of which can be connected to the lower end of the hinge assembly 20 in another tie rod connection node 100 on the upper level.

[0070] In the two tie rod connection nodes 100 described above, each including only one tie rod 40, the mounting cavity 11 can also be configured as a corresponding blind hole structure. For example, for the uppermost tie rod connection node 100, the mounting cavity 11 at its hinge frame 14 can be a blind hole structure with an opening at the bottom, thus preventing rainwater and other debris from entering the mounting cavity 11 through the upper opening and corroding the hinge assembly 20 and the pin 30. For the lowermost tie rod connection node 100, the mounting cavity 11 at its hinge frame 14 can be a blind hole structure with an opening at the top. This allows the mounting cavity 11 and the hinge structure to be hidden downwards, preventing the hinge assembly 20 and the pin 30 from being exposed downwards, resulting in better concealment and aesthetics.

[0071] In this embodiment, the tie rod connection node 100 can be a building structure primarily composed of metal components, or it can be made of other polymer materials with high structural strength. The connecting beam 10 can be formed using at least one type of profile. For example, the cross-sectional shape of the profile can include I-shaped, H-shaped, rectangular, channel-shaped, and U-shaped, etc. Furthermore, the profile can be composed of one or more of metal or non-metal profiles, without limitation.

[0072] It should be noted that, for the aforementioned profile, the cross-sectional shape of the connecting beam 10 in the direction perpendicular to the first straight line is the shape and structure. Taking the first connecting section 12 as an example, the I-beam profile refers to the first connecting section 12, which may include two flanges arranged horizontally in the vertical direction. The middle of these two flanges is connected by a supporting web. This supporting web can be arranged perpendicular to the front-rear direction, with its upper edge connected to the upper flange and its lower edge connected to the lower flange. The connection position between the supporting web and the flange can be located in the middle of the flange in the front-rear direction. When the widths of the upper and lower flanges are inconsistent in the front-rear direction, the first connecting section 12 is the corresponding I-beam profile.

[0073] When the upper and lower flanges have the same width in the front-to-back direction, the first connecting section 12 is the corresponding H-shaped profile. If the supporting web connects to the front or rear of the upper and lower flanges in the front-to-back direction, the first connecting section 12 is the corresponding channel profile. If the supporting web of the channel profile is connected to the two flanges by rounded corners, it is a U-shaped profile.

[0074] Furthermore, if the first connecting section 12 may include two flanges spaced apart in the vertical direction and two supporting webs spaced apart in the front-rear direction, the upper edges of the two supporting webs may be connected to the front and rear edges of the upper flange, and the lower edges of the two supporting webs may be connected to the front and rear edges of the lower flange, so that the first connecting section 12 can be a rectangular profile.

[0075] Subject to meeting the structural design requirements of the building, the material of the aforementioned profiles can be either metallic or non-metallic materials that meet structural strength requirements. Preferably, due to its advantages such as high structural strength and low cost, steel can be widely used in various components of the aforementioned tie rod connection node 100.

[0076] Continue to refer to Figure 4 For the connecting beam 10, the hinge frame 14 can be a frame-shaped structure on a cross-section perpendicular to the vertical direction, used to accommodate... Figure 2 The hinge assembly 20 shown, and the hinge frame 14, may have two opposing edges in the front-to-back direction for connecting the two ends of the pin 30. Exemplarily, the hinge frame 14 may include a first bent segment 141 and a second bent segment 142, the cross-section of which may be one or more of the following shapes: I-shaped, H-shaped, rectangular, slotted, and U-shaped. In the left-to-right direction, the first end (i.e., the left end) of the first bent segment 141 and the first end (i.e., the left end) of the second bent segment 142 may be connected to the right end of the first connecting segment 12. Correspondingly, the second end (i.e., the right end) of the first bent segment 141 and the second end (i.e., the right end) of the second bent segment 142 may be connected to the left end of the second connecting segment 13. This connection may be fixed by welding. The first bending segment 141 and the second bending segment 142 can be arranged in the front-back direction, and at least one of the first bending segment 141 and the second bending segment 142 can be bent away from the other in the front-back direction and form an installation cavity 11 at intervals.

[0077] For example, the first bending segment 141 on the rear side can be bent backward, or the second bending segment 142 on the front side can be bent forward. Alternatively, the first bending segment 141 on the rear side can be bent backward, and the second bending segment 142 on the front side can be bent forward simultaneously. In both cases, a mounting cavity 11 can be formed between the first bending segment 141 and the second bending segment 142 in the front-rear direction.

[0078] In a cross-section perpendicular to the vertical direction, at least one of the first bending segment 141 and the second bending segment 142 can be an arc-shaped structure extending in the left-right direction. For example, the hinge frame 14 including the first bending segment 141 and the second bending segment 142 can have a main body shape that is an arc-shaped structure such as a circular ring or an elliptical ring.

[0079] Alternatively, in a cross-section perpendicular to the vertical direction, at least one of the first bending segment 141 and the second bending segment 142 can be a multi-segment bending structure with an acute angle, a right angle, or an obtuse angle. For example, the hinge frame 14 including the first bending segment 141 and the second bending segment 142 can have a polygonal frame structure, which can include triangular frames, square frames, rectangular frames, pentagonal frames, hexagonal frames, and octagonal frames, etc.

[0080] For example, since the force of the hinge assembly 20 can be applied to the front and rear sides of the hinge frame 14 through the pin 30, the hinge frame 14 can be configured to be an axisymmetric or centrally symmetric structure relative to one of the axes in the front and rear directions, so as to facilitate the uniform force on the hinge frame 14.

[0081] It should be noted that, in the embodiments of this application, [the following is used] Figure 4 Taking the hinge frame 14 with mounting cavity 11 as an example, the cross-sectional shape of the hinge frame 14 in the vertical direction can be an arc, a ring, an elliptical ring, or a multi-sided structure. Furthermore, the corresponding hinge frame 14 can be formed by using one or more profiles with cross-sectional shapes of I-shape, H-shape, rectangle, channel shape, and U-shape as the first bending segment 141 and the second bending segment 142.

[0082] like Figure 5 As shown, Figure 5 for Figure 2 The diagram shows a top view of the tie rod connection node 100. The first bent segment 141 may include a third connecting segment 1411, a first hinge segment 1412, and a fourth connecting segment 1413 connected in sequence. The third connecting segment 1411 and the fourth connecting segment 1413 may be located on the side of the first hinge segment 1412 closest to the second bent segment 142 (i.e., the front side), and may be bent and connected to the left and right ends of the first hinge segment 1412. Correspondingly, the second bent segment 142 may include a fifth connecting segment 1421, a second hinge segment 1422, and a sixth connecting segment 1423 connected in sequence. The fifth connecting segment 1421 and the sixth connecting segment 1423 may be located on the side of the second hinge segment 1422 closest to the first bent segment 141 (i.e., the rear side), and may be bent and connected to the left and right ends of the second hinge segment 1422. This allows a mounting cavity 11 to be formed between the first bent segment 141 and the second bent segment 142.

[0083] For example, such as Figure 5As shown, in sections parallel to the left-right and front-back directions, the included angles formed by the third connecting segment 1411 and the first hinge segment 1412, the fourth connecting segment 1413 and the first hinge segment 1412, the fifth connecting segment 1421 and the second hinge segment 1422, and the sixth connecting segment 1423 and the second hinge segment 1422 can be obtuse angles. Correspondingly, the left ends of the third connecting segment 1411 and the fifth connecting segment 1421 can be connected to the right ends of the first connecting segment 12, and the right ends of the fourth connecting segment 1413 and the sixth connecting segment 1423 can be connected to the left ends of the second connecting segment 13, so that the first connecting segment 12 and the second connecting segment 13 can pass through the hinge frame 14 (e.g., Figure 4 (As shown) Bears the force at the hinge assembly 20. At this time, the included angle between the third connecting segment 1411 and the fifth connecting segment 1421 can be acute, right, or obtuse, so that the mounting cavity 11 is approximately a hexagonal structure symmetrical in the left-right direction within this cross-section. The included angle between the first connecting segment 12 and the third connecting segment 1411 (and the fifth connecting segment 1421) can be obtuse. Correspondingly, the included angle between the second connecting segment 13 and the fourth connecting segment 1413 (and the sixth connecting segment 1423) can also be obtuse. This allows the hinge frame 14 and the first connecting segments 12 and the second connecting segments 13 on both sides to bear a large force in the left-right direction. Correspondingly, the structure of the first bending segment 141 and the second bending segment 142 can also bear a large force in the left-right direction. Furthermore, it facilitates the connection and installation (such as welding) of the hinge frame 14, the first connecting segment 12, and the second connecting segment 13.

[0084] Furthermore, within the cross-section parallel to the left-right and front-back directions, the included angles between the third connecting segment 1411 and the first hinge segment 1412, the fourth connecting segment 1413 and the first hinge segment 1412, the fifth connecting segment 1421 and the second hinge segment 1422, and the sixth connecting segment 1423 and the second hinge segment 1422 can also be right angles. In this case, the front end of the third connecting segment 1411 can be connected to the rear end of the fifth connecting segment 1421, and can be perpendicularly connected to the first connecting segment 12 on the left side of the connection point. Correspondingly, the front end of the fourth connecting segment 1413 can be connected to the rear end of the sixth connecting segment 1423, and can be perpendicularly connected to the second connecting segment 13 on the right side of the connection point. This forms an installation cavity 11 with a cross-sectional shape approximately rectangular or square, resulting in a simple structure.

[0085] In the above embodiments, for the components in the connecting beam 10, such as the first connecting segment 12, the second connecting segment 13, the third connecting segment 1411, the first hinge segment 1412, the fourth connecting segment 1413, the fifth connecting segment 1421, the second hinge segment 1422, and the sixth connecting segment 1423, when connecting and installing multiple adjacent components, multiple adjacent upper flange plates can be connected in contact, multiple adjacent lower flange plates can be connected in contact, and multiple adjacent supporting web plates can be connected in contact. For example, the above components can be fixedly connected by welding so that the connecting beam 10 has a stable structure and can bear a large force.

[0086] In some other embodiments, the connecting beam 10 may be made of a profile with a square or rectangular cross-sectional shape. For example... Figure 6 As shown, at this time, holes can be made in at least one of the upper and lower flanges along the vertical direction at the corresponding positions, thereby forming a mounting cavity 11 with a blind hole or through hole structure. That is, the part of the connecting beam 10 near the mounting cavity 11 can be regarded as a hinge frame to form a connecting beam 10 with an integral structure including the first connecting section 12, the hinge frame and the second connecting section 13, without the need to set an additional hinge frame. At this time, corresponding hinge holes 15 can be opened on the webs on the front and rear sides of the mounting cavity 11.

[0087] For example, the two supporting webs on the front and rear sides of the mounting cavity 11 can serve as the front and rear sidewalls of the mounting cavity 11, supporting the front and rear ends of the connecting pin 30. Alternatively, hinge holes 15 can be provided on the two supporting webs for inserting the mounting pin 30. In this case, the connecting beam 10 is equivalent to forming the mounting cavity 11 and the corresponding hinge frame 14 structure by setting openings on the basis of a whole square steel profile. The square steel profiles on the left and right sides of the mounting cavity 11 are equivalent to the first connecting section 12 and the second connecting section 13 of the hinge frame 14, which is not limited.

[0088] Or, as Figure 7 As shown, the connecting beam 10 can also be composed of two profiles spaced apart in the front-to-back direction. Alternatively, the connecting beam 10 can form a mounting cavity 11 at least at the mounting cavity 11, with two profiles spaced apart in the front-to-back direction, to accommodate the hinge assembly and pin. In this case, hinge holes 15 can be formed on the webs of the corresponding profiles. It should be noted that, in this embodiment, the profiles constituting the connecting beam 10 can be any one or two of the following cross-sectional shapes: I-shaped, H-shaped, rectangular, channel-shaped, and U-shaped.

[0089] For example, if the connecting beam 10 is formed by two rectangular profiles (such as square steel) spaced apart, the two hinge holes 15 at each mounting cavity 11 can penetrate through the four webs in the front-back direction, or they can penetrate only the two webs near the mounting cavity 11 to form two hinge holes 15, so as to form a mounting cavity 11 for mounting the hinge assembly 20 and the pin 30.

[0090] Alternatively, if the connecting beam 10 is composed of two I-shaped or H-shaped profiles spaced apart in the front-to-back direction, the webs of the two profiles can be arranged perpendicular to the front-to-back direction, and hinge holes 15 can be opened at corresponding positions of the two webs to form mounting cavities 11 for mounting the hinge assembly 20 and the pin 30.

[0091] Alternatively, if the connecting beam 10 consists of two channel-shaped or U-shaped profiles spaced apart in the front-to-back direction, the webs of the two profiles can be arranged perpendicular to the front-to-back direction, and hinge holes 15 can be opened at corresponding positions on the two webs to form mounting cavities 11 for installing the hinge assembly 20 and the pin 30. In this example, since the webs of the profiles can be located on the front or rear side in the front-to-back direction, the webs of the two profiles can be brought closer to each other in the front-to-back direction, which helps to improve the stability of the connection with the pin 30 and the hinge assembly 20.

[0092] It should be noted that in the example described above where two profiles are spaced apart in the front-to-back direction to form a connecting beam 10, two reinforcing members, such as profiles or plates extending in the front-to-back direction, can be sequentially arranged on the left and right sides of the two aligned hinge holes 15. The front and rear ends of one reinforcing member located on the left side of the hinge hole 15 can be connected to the web and / or flange plates of the two profiles, and the front and rear ends of the other reinforcing member located on the right side of the hinge hole 15 can also be connected to the web and / or flange plates of the two profiles, so that the two reinforcing members can form a stable frame structure (i.e., hinge frame 14) with a portion of the profile at the hinge hole 15, for the purpose of stably connecting the pin 30 and the hinge assembly 20.

[0093] Since the tie rod 40 lacks a suitable stress-bearing connection point when it passes through the connecting beam 10 in the vertical direction, the hinge frame 14 and pin 30 are used to hinge the connecting beam 10 and the tie rod, thereby concealing the hinge structure and improving its aesthetics.

[0094] Furthermore, within the hinge frame 14, at least two hinge holes 15 distributed along the third straight line can be formed on the hinge frame 14 or the corresponding support web of the hinge segment. While the two ends of the pin 30 are inserted and installed along the third straight line, the two support webs arranged approximately perpendicular to the third straight line can stably bear the force exerted by the hinge assembly 20 on the connecting beam 10 through the pin 30. Alternatively, it is not necessary to form hinge holes in the hinge frame 14; simply welding the two ends of the pin 30 to the hinge frame 14 or the corresponding support web of the hinge segment can also satisfy the hinged installation of the hinge assembly 20 to the hinge frame 14 through the pin 30.

[0095] In some embodiments, such as Figure 8 As shown, Figure 8 for Figure 5 The diagram shows a right-side sectional view of the tie rod connection node 100. The connecting beam 10 may also include two sleeves 16, which may be at least partially located within the mounting cavity 11 and connected to two hinge holes 15 (as shown in the diagram). Figure 4 As shown, each sleeve 16 is configured in a one-to-one correspondence with a hinge hole 15 along the front-to-back direction (i.e., the third straight line direction) and can be fixedly connected to the hinge frame 14. Thus, the two sleeves 16 can be used to insert and install the front and rear ends of the pin 30, increasing the effective contact area between the front and rear ends of the pin 30 and the hinge frame 14 through the sleeves 16, thereby improving the stability of the insertion and installation of the pin 30 and the hinge frame 14.

[0096] For example, the outer diameter of the sleeve 16 can be set to be less than or equal to the inner diameter of the hinge hole 15. Combined with... Figure 8 The sleeve 16 can be partially located within the mounting cavity 11, and one end of the sleeve 16 can be inserted into a corresponding hinge hole 15 (e.g., Figure 4 As shown, the sleeve 16 can be connected and installed with the hinge frame 14. Alternatively, the sleeve 16 can be connected and fixed to the support web with the hinge hole 15. Based on this, the outer diameter of the pin 30 can be slightly smaller than the inner diameter of the sleeve 16, and the front and rear ends of the pin 30 can be inserted into two sleeves 16 arranged at a distance from each other, thereby realizing the hinged installation of the hinge assembly 20.

[0097] Alternatively, the inner diameter of the sleeve 16 can be set to be equal to the inner diameter of the hinge hole 15, and slightly larger than the outer diameter of the pin 30. In this case, both sleeves 16 can be placed in the mounting cavity 11, with one end of one sleeve 16 positioned close to the side wall of one hinge hole 15, aligning with the inner holes of the hinge hole 15 and the sleeve 16. The sleeve 16 and the support web with the hinge hole 15 can then be fixedly connected by welding. Based on this, the outer diameter of the pin 30 can be slightly smaller than the inner diameters of the sleeve 16 and the hinge hole 15, allowing the front and rear ends of the pin 30 to be inserted sequentially into one sleeve 16 and one hinge hole 15, thereby achieving the hinged installation of the hinge assembly 20.

[0098] To prevent the pin 30 from sliding in the front-to-back direction and disengaging from the hinge frame 14, such as Figure 8 As shown, the connecting beam 10 may also include multiple limiting members 17. Along the front-rear direction, the pin 30 may be located among the multiple limiting members 17. The front end or rear end of the pin 30 may be connected and installed with at least one limiting member 17, and the hinge hole 15 may be located among the multiple limiting members 17 in the front-rear direction. For example, one or more limiting members 17 on the front side may be connected to the front end face of the pin 30 and located in front of a hinge hole 15. Correspondingly, one or more limiting members 17 on the rear side may be connected to the rear end face of the pin 30 and located in rear of a hinge hole 15. The outline dimension of the limiting member 17 may be set larger than the inner diameter dimension of the hinge hole 15 so that the limiting members 17 at both ends of the pin 30 can restrict the degree of freedom of the pin 30 in the front-rear direction.

[0099] For example, the limiting member 17 can be a sheet-like structure with one or more through holes, and the end face of the pin 30 is also provided with a corresponding threaded hole, so that the limiting member 17 and the end face of the pin 30 can be connected by bolts. Taking the limiting member 17 as a circular sheet-like structure as an example, the diameter of the limiting member 17 can be set to be larger than the inner diameter of the hinge hole 15, thereby restricting the degree of freedom of the pin 30 in the front-rear direction. In addition, if one end of the sleeve 16 passes through the hinge hole 15 and is located outside the mounting cavity 11, the diameter of the limiting member 17 can also be set to be larger than the inner diameter of the sleeve 16, which can also restrict the degree of freedom of the pin 30 in its axial direction.

[0100] It should be noted that, in the above embodiments, for the circular sheet-like limiting member 17, its diameter can also be set to be at least one centimeter larger than the diameter of the pin 30, which can also restrict the degree of freedom of the pin 30 in its axial direction. In this way, the limiting structures at both ends of the pin 30 can have smaller structural dimensions, avoid the protrusion setting at the hinge position, and help improve the decorative effect of the appearance of the tie rod connection node 100.

[0101] In other embodiments, if the limiting member 17 is a plate-like or rod-like structure, while the limiting member 17 can be installed with screws on the end face of the pin 30, the diameter of the limiting member 17 can be considered as the length of the plate-like or rod-like structure. Alternatively, the limiting member 17 can be a nut structure, with corresponding external threads at both ends of the pin 30, which can also restrict the axial degree of freedom of the pin 30, and the structure is simple. This application does not limit this aspect.

[0102] Based on this, continue to refer to Figure 8 The connecting beam 10 may also include multiple ribs 18, and each sleeve 16 can be connected to the hinge frame 14 through one or more ribs 18 to improve the connection stiffness and strength between the sleeve 16 and the hinge frame 14, thereby improving the stability of the hinged installation of the hinge frame 14 and the hinge assembly 20. For example, multiple ribs 18 can be disposed in the mounting cavity 11 to avoid the exposed ribs 18 affecting the appearance of the hinge frame 14.

[0103] Taking two sleeves 16 corresponding to four ribs 18 as an example, combined with Figure 9 , Figure 9 for Figure 8 The diagram shows a side view of the mounting cavity 11 within the hinge frame 14. A rib 18 can be installed on each of the upper and lower sides of a sleeve 16, and these two ribs 18 can be arranged perpendicular to the front-back direction. One side edge of one rib 18 can contact and connect with the outer surface of the sleeve 16, the second side edge of the rib 18 can contact and connect with the supporting web (such as at the first hinge section 1412), and the third side edge of the rib 18 can contact and connect with the adjacent upper or lower flange plate, so that the force borne by the sleeve 16 can be evenly distributed within the hinge frame 14 along the vertical direction through the two ribs 18.

[0104] Alternatively, a rib 18 can be provided on each of the left and right sides of each sleeve 16, and at least two adjacent edges of the rib 18 can be connected to the outer surface of the sleeve 16 and the supporting web, which can also increase the connection strength between the sleeve 16 and the hinge frame 14. For example, the rib 18 can be connected and installed at any position in the four directions of the sleeve 16 (up, down, left, and right) to improve the structural strength of the connection between the sleeve 16 and the hinge frame 14.

[0105] In some embodiments, such as Figure 10 As shown, Figure 10 for Figure 5The diagram shows an exploded view of the hinge assembly 20. The hinge assembly 20 may include a hinge member 22 and a bearing member 23. The hinge member 22 may be at least partially located within the mounting cavity 11, and the portion of the hinge member 22 located within the mounting cavity 11 may have a first through hole 21. Taking the first through hole 21 as an example where the axial direction of the first through hole 21 is parallel to the front-back direction (i.e., the third linear direction) during installation, the bearing member 23 may be installed within the first through hole 21, such as by being approximately coaxial with the first through hole 21. The pin 30 may be inserted into the first through hole 21 along the front-back direction via the bearing member 23 for hinged installation of the hinge member 22. Since the pin 30 and the sidewall of the first through hole 21 can slide relative to each other, the bearing member 23 helps reduce the frictional resistance between the pin 30 and the hinge member 22, thereby reducing the wear of the pin 30.

[0106] For example, the bearing component 23 located within the first through hole 21 can be interference-fitted with the first through hole to ensure a relatively stable installation of the bearing component 23 within the first through hole 21. The bearing component 23 can be a rolling bearing such as a ball bearing or a roller bearing. Alternatively, the bearing component 23 can also be a sliding bearing. For example, the bearing component 23 can be a relatively smooth sleeve located between the first through hole 21 and the pin 30, which can be lubricated to reduce the frictional resistance between the pin 30 and the sidewall of the first through hole 21. Alternatively, the bearing component 23 can be omitted; simply adjusting the inner diameter of the first through hole 21 to be slightly larger than the outer diameter of the pin 30, or inserting the pin 30 into the first through hole 21 in the front-to-back direction, can be used for the hinged installation of the hinge component 22.

[0107] It should be noted that if the pin 30 is directly inserted into the first through hole 21 and installed in contact with the hinge 22, the pin 30 can have an interference fit with the first through hole 21. Alternatively, the pin 30 can also have a radial clearance with the first through hole 21 after being inserted into it. If the pin 30 is installed in the first through hole 21 through the bearing 23, the pin 30 can be inserted axially into the bearing 23 and have an interference fit with the bearing 23, and the bearing 23 can also have an interference fit with the first through hole.

[0108] In some embodiments, bearing component 23 is an example of a spherical plain bearing (a type of sliding bearing). Figure 11 As shown, Figure 11 for Figure 10 The diagram shows an exploded view of a bearing component 23. The bearing component 23 may include an outer ring 231 and an inner ring 232, both of which may be annular structures. Figure 12 , Figure 13 and Figure 14 , Figure 12 for Figure 11 A cross-sectional view of the outer ring 231 shown. Figure 13 for Figure 11 A cross-sectional view of the inner ring 232 shown. Figure 14 for Figure 11 The diagram shows a cross-sectional view of the connection and installation of the outer ring member 231 and the inner ring member. The outer ring member 231 can be fitted onto the outside of the inner ring member 232 so that the inner spherical surface of the outer ring member 231 and the outer spherical surface of the inner ring member 232 can contact or adhere and slide together.

[0109] Based on this, combined Figure 15 , Figure 15 for Figure 8 A partially enlarged schematic diagram at point A. The outer ring 231 can be installed in the first through hole 21, such as by interference fit with the hinge 22. In this case, the inner ring 232 can have a second through hole 233 along its axial direction, and the pin 30 can be inserted into the second through hole 233 in the front-rear direction and hinged to the hinge 22. Based on this, for a spherical bearing including the inner ring 232 and the inner ring 231, the inner ring 232 can not only rotate relative to the outer ring 231 around its axis, but also rotate around the center of the outer ring 231 in three-dimensional space, so that the axis of the inner ring 232 can have an angle relative to the axis of the outer ring 231. This increases the angle adjustment range of the outer hinge 22 relative to the connecting beam 10 or the pin 30.

[0110] For example, for the above-mentioned tie rod connection node 100, between the hinge assembly 20 and the pin 30, the hinge assembly 20 can not only rotate around the axis of the pin 30, but also swing relative to the axis of the pin 30 within an allowable space, so that the tie rod 40 connected above and below can have a large angle adjustment range, and the hinge mounting member at the tie rod connection node 100 can absorb errors and has the effect of absorbing and offsetting internal stress.

[0111] To prevent the bearing component 23 installed in the first through hole 21 from dislodging from the first through hole 21 along its axial direction, such as Figure 10 As shown, the hinge assembly 20 may further include a plurality of first positioning rings 24, which may be located within the mounting cavity 11. Along the front-rear direction (i.e., the axial direction of the first through hole 21), the plurality of first positioning rings 24 may be distributed on the front and rear sides of the hinge member 22 and connected to the hinge member 22. The inner diameter of the first positioning ring 24 may be smaller than the outer diameter of the outer ring member 231. The inner diameter of the first positioning ring 24 may be greater than or equal to the inner diameter of the second through hole 233, or the inner diameter of the first positioning ring 24 may be greater than or equal to the outer ring member 231 (e.g., ...). Figure 15The inner diameter dimension is shown. In this way, by installing the first positioning rings 24 aligned on the front and rear sides of the first through hole 21, it is not only convenient to insert and install the pin 30, but also to prevent the outer ring 231 from disengaging from the hinge 22 at both ends of the first through hole 21 in the front-rear direction.

[0112] It should be noted that, for spherical plain bearings, the installed outer ring 231 can restrict the axial direction of the inner ring 232. For example, the outer ring 231 can be an axially detachable two-ring structure, forming an internal spherical surface and spherical chamber structure for slidingly mounting the inner ring 232. To allow the inner ring 232 to stably deflect at multiple angles relative to the outer ring 231 and its axis, when the axis of the inner ring 232 coincides with the axis of the outer ring 231, the inner ring 232 can be configured to have a larger axial width relative to the outer ring 231. For example, the front end of the inner ring 232 can protrude beyond the front end of the outer ring 231, and the rear end of the inner ring 232 can protrude beyond the rear end of the outer ring 231.

[0113] For example, such as Figure 10 As shown, when connecting the first positioning ring 24 and the hinge 22, along the axial direction of the first through hole 21, the hinge 22 can be provided with multiple positioning holes 251, and these multiple positioning holes 251 can be distributed at intervals around the axis of the first through hole 21 on the outer side of the first through hole 21 away from its axis. Correspondingly, the first positioning ring 24 can be provided with multiple connecting through holes 252. Combined with... Figure 15 Taking the case where there are two first positioning rings 24 and the positioning hole 251 is a through hole structure as an example, a long bolt or rivet or other connecting parts can be used to pass through the first through hole 21 axially in sequence through a connecting through hole 252, a positioning hole 251 and a connecting through hole 252, so as to press the hinge 22 between the two first positioning rings 24.

[0114] Furthermore, the positioning hole 251 can also be a blind-hole threaded hole, and can be arranged on the front and rear sides of the hinge 22. Subsequently, a first positioning ring 24 can be installed on one side of the hinge 22 by passing screws or bolts through a connecting through hole 252 and a positioning hole 251 in sequence, thereby restricting the axial freedom of the inner and outer rings 231 of the first through hole 21. Alternatively, the first positioning ring 24 and the hinge 22 can be connected by welding or snap-fit, which is not limited.

[0115] In the above embodiment, along the axial direction of the outer ring 231, if the width of the outer ring 231 is greater than or equal to the depth of the first through hole 21, the outer ring 231 can be pressed and installed between the two first positioning rings 24 in the above manner. Even if the width of the outer ring 231 is slightly smaller than the depth of the first through hole 21, the positioning and installation of the outer ring 231 can still be relatively stable in the above manner, that is, the displacement of the outer ring 231 in its axial direction is small.

[0116] In some other embodiments, reference continues to be made to... Figure 10 The hinge assembly 20 may also include at least one second locating ring 26. Combined Figure 15 The second positioning ring 26 can be installed within the first through hole 21. The inner diameter of the second positioning ring 26 can be smaller than the outer diameter of the outer ring 231, and the outer diameter of the second positioning ring 26 can be larger than the inner diameter of the first positioning ring 24. Based on this, along the axial direction of the first through hole 21, the second positioning ring 26 can be installed between the outer ring 231 and the first positioning ring 24, so that the second positioning ring 26 can be press-fitted between the outer ring 231 and the first positioning ring 24. Thus, by providing one or more second positioning rings 26 on the front and / or rear sides of the outer ring 231, the outer ring 231 can be press-fitted between multiple first positioning rings 24 along the axial direction of the first through hole 21.

[0117] For example, the number of first positioning rings 24 and the number of second positioning rings 26 can both be two, and one second positioning ring 26 and one first positioning ring 24 can be sequentially arranged on the front or rear side of the outer ring member 231. Along the axial direction of the first through hole 21, the sum of the width dimensions of the two second positioning rings 26 and the outer ring member 231 can be greater than or equal to the axial depth dimension of the first through hole, so as to position and install the bearing member 23 in the middle region of the first through hole 21.

[0118] Correspondingly, the inner diameter of the first positioning ring 24 and the inner diameter of the second positioning ring 26 can be greater than or equal to the minimum inner diameter of the outer ring 231, and less than or equal to the maximum inner diameter of the outer ring 231. If the inner diameter of the first positioning ring 24 and the second positioning ring 26 can be equal to the maximum inner diameter of the outer ring, the arrangement of the first positioning ring 24 and the second positioning ring 26 can avoid affecting the deflection range of the inner ring 232 and the pin 30. Specifically, in a plane perpendicular to the axial direction (e.g., along the vertical direction), the maximum inner diameter of the outer ring 231 is the inner diameter at its centroid, which can also be considered as the spherical outer diameter of the inner ring 232. The minimum inner diameter of the outer ring 231 is the inner diameter at its front or rear end in the vertical direction.

[0119] In some embodiments, such as Figure 10As shown, the hinge assembly 20 can be connected to the pull rod 40 (e.g., the upper end) via the first end (i.e., the upper end) and / or the second end (i.e., the lower end) of the hinge member 22. Figure 8 (As shown) Connection. When connecting the hinge 22 and the tie rod 40, the two components can be fixedly connected by welding, or they can be detachably connected by means of screw connection or other methods.

[0120] For example, such as Figure 8 As shown, an external thread can be provided axially around the end of the tie rod 40 near the hinge assembly 20. (Combined) Figure 8 and Figure 10 Corresponding threaded holes can be provided on the upper and / or lower end faces of the hinge 22. One end of the pull rod 40 can then be inserted into the threaded hole and rotated to achieve a detachable connection between the pull rod 40 and one end of the hinge 22. Furthermore, the hinge assembly 20 may also include a locking nut 27, which can be fitted onto the pull rod 40. Tightening the locking nut 27 towards the hinge 22 improves the connection strength between the pull rod 40 and the hinge 22. Additionally, along the length of the pull rod 40, the outer diameter of the locking nut 27 can gradually decrease towards the hinge 22, resulting in a neater appearance.

[0121] In some other embodiments, a sleeve with internal threads can be provided at the end of the pull rod 40, and the upper and lower ends of the hinge 22 can be provided with corresponding external threads, which can also be used for the detachable connection between the pull rod 40 and the hinge 22.

[0122] On the other hand, this application also provides a tie-rod suspension building system 1000. For example... Figure 16 As shown, Figure 16 This is a structural schematic diagram of a tie-rod suspended building system 1000 provided in an embodiment of this application. The tie-rod suspended building system 1000 may include at least one tie-rod connection node 100 as described above and multiple floor frames 200. Along the vertical direction (i.e., the second straight line direction), the multiple floor frames 200 may be arranged at intervals, and at least two adjacent floor frames 200 may be suspended and connected by one or more tie-rod connection nodes 100. For example, each floor frame 200 may be formed by multiple crossbeams 201 connected in an alternating manner. The multiple crossbeams 201 may be made of one or more profiles with cross-sectional shapes including I-shaped, H-shaped, rectangular, channel-shaped, and U-shaped. The connecting beam 10 in the tie-rod connection node 100 may also be considered as part of the structure of the crossbeam 201, used for hinged installation of tie rods 40 to suspend and support the floor frame 200.

[0123] In some embodiments, such as Figure 16As shown, at the two floor frames 200 on the upper and lower sides, a tie rod connection node 100 with a hanger 40 installed on one side can be used to suspend and connect to an adjacent floor frame 200. For example, at the lowermost floor frame 200, one or more tie rod connection nodes 100 can be installed at its crossbeam 201, and can be connected to the upper tie rod 40 through the upper end of the hinge 22, so that the upper floor frame 200 can bear the load of the lower floor frame 200.

[0124] Furthermore, in some of the middle floor racks 200, each floor rack 200 can be suspended and connected to adjacent floor racks 200 via multiple tie rod connection nodes 100. Based on this, in the vertical direction, some of the crossbeams 201 in the middle floor racks 200 can also be suspended and connected to adjacent floor racks 200 via single-sided tie rod connection nodes 100 of the upper or lower connecting tie rods 40. This structure also applies to the lowest floor rack 200, in which case the corresponding mounting cavity 11 can be designed as a blind hole structure with an open top.

[0125] In some embodiments, for the two floor frames 200 on the upper and lower sides, if some or all of the crossbeams 201 of the floor frame 200 are composed of square steel profiles, it is not necessary to connect them to the adjacent floor frame 200 via the aforementioned tie rod connection node 100. For example, taking a crossbeam 201 in the upper floor frame 200 that includes square steel profiles as an example, aligned insertion holes can be made on the upper and lower flange plates of the crossbeam 201. Then, the upper end of the tie rod 40 can be inserted into the insertion hole from bottom to top, allowing the upper end of the tie rod 40 to protrude upwards from the upper flange plate. Subsequently, a limiting hinge and a limiting nut can be connected to the upper end of the tie rod 40, so that the limiting hinge can be located between the limiting nut and the upper flange plate, and the outline dimension of the limiting hinge can be larger than the outline dimension of the insertion hole, thus achieving the connection and installation of the tie rod 40 and the crossbeam 201. Furthermore, this structural installation is also applicable to the middle floor frame 200 and the lower floor frame 200 formed by square steel, without limitation.

[0126] It should be noted that in related technical solutions, when the tie rod is installed via a lower support connection of an integral structure, if the connection between the tie rod and one of the crossbeams is broken, the entire tie rod suspension system above will fail, resulting in poor structural stability. Furthermore, the tie rod suspension system installed in this way requires simultaneous support and fixation of all the crossbeams on all floors during maintenance, which is cumbersome. With the improved design described in this application, when using the tie rod connection node 100 to suspend and connect multi-story steel structure buildings, multiple floor frames 200 can be connected to form a stable overall frame structure, making the overall stress distribution safer. In addition, since the hinge assembly 20 is detachably connected to the connecting beam 10 and the tie rod 40, maintenance work on each floor of the floor frame 200 can be performed through disassembly and installation, which is convenient and does not affect the overall stability of the building.

[0127] The design of the aforementioned tie rod connection nodes 100 ensures that each floor frame is independently stressed and does not affect others. Even if some tie rod connection nodes 100 on one floor are damaged, the remaining floor frames remain unaffected. In the event of an extreme natural disaster exceeding the design force limit, if a tie rod connection node 100 on a certain floor is damaged, that floor will become unstable. However, the tension of the tie rods 40 on the upper floor frames will also disappear, reducing the stress on the tie rods 40 of the upper floor frames. This indirectly protects the upper tie rods 40 from damage, making the upper floor frame structure safer.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of protection described in the claims.
