Description

Technical Field

[0001] The present application relates to the technical field of building structure connection, and in particular to a tie rod connection node. Background Art

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

[0003] The traditional steel tie rod node is a segmented fork-ear connection. This node requires the ear plate to be welded to the steel beam, and there is no special requirement for the steel beam. However, the ear plate anchor is generally large, and the hinged structure at the ear plate is completely exposed to the outside of the beam. The exposed ear plate may be hit or corroded, and the exposed hinged structure at the ear plate will also affect the aesthetics of the steel structure building. Utility Model Content

[0004] The purpose of the present application is to provide a tie rod connection node, aiming to solve the problem of the hinge structure at the end of the tie rod being exposed.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] Some embodiments of the present application provide a pull rod connection node, including a connecting beam, a hinge assembly, a pin and at least one pull rod. The connecting beam extends along a first linear direction, and the connecting beam is provided with a mounting cavity, and the mounting cavity is provided with an opening on at least one side along a second linear direction, and the first linear direction and the second linear direction intersect. The hinge assembly is at least partially located in the mounting cavity, and the portion of the hinge assembly located in the mounting cavity is provided with a first through hole facing the side wall of the mounting cavity. Along a third linear direction, the pin is inserted into the first through hole, and both ends of the pin are connected to the connecting beams at the two side walls of the mounting cavity, so that the hinge assembly is hingedly installed with the connecting beam. The third linear direction is perpendicular to the first linear direction and the second linear direction. Along the second linear direction, at the opening of the mounting cavity, at least one end of the hinge assembly is detachably connected to a pull rod.

[0007] In this way, taking the second straight line direction as the up and down direction as an example, the upper end of the upper pull rod can be connected and installed with the upper crossbeam (or connecting beam) so that the upper crossbeam can bear the force at the connection node of the pull rod of this layer. Correspondingly, the lower end of the lower pull rod can be connected and installed with the lower crossbeam (or connecting beam) to bear the force of the lower crossbeam. Since the hinge assembly is hingedly installed with the connecting beam through a pin shaft, the pull rod connected to the connecting beam through the hinge assembly and the connecting beam can bear a larger force. Since the hinged part of the hinge assembly is hidden and installed in the installation cavity of the connecting beam, it avoids the situation where the protruding and exposed hinge structure is easily damaged by impact or corroded. At the same time, the overall aesthetics of the steel structure building can be improved by less exposed hinge structure.

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, so as to position and install the outer ring in the first through hole.

[0011] In some embodiments, the hinge assembly further comprises at least one second positioning ring installed in the first through hole, wherein the inner diameter of the second positioning ring is smaller than the inner diameter of the outer ring, and the outer diameter of the second positioning ring is larger than the inner diameter of the first positioning ring. Along the axial direction of the first through hole, the second positioning ring is located between the outer ring and the first positioning ring, so that the outer ring is extruded and installed between the plurality of first positioning rings.

[0012] In some embodiments, the connecting beam includes a first connecting section, a second connecting section, and a hinge frame. Along the first straight line direction, the first end of the hinge frame is connected to the first connecting section, and the second end of the hinge frame is connected to the second connecting section.

Along the first straight line direction, the first end of the first bending section, the first end of the second bending section and the first connecting section are connected, and the second end of the second bending section, the second end of the first bending section and the second connecting section are connected. The first bending section and the second bending section are arranged along a third straight line direction, and at least one of the first bending section and the second bending section is bent in a direction away from the other to form a mounting cavity. The first bending section and the second bending section are sequentially provided with hinge holes along the third straight line direction.

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

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

[0016] In some embodiments, in a cross section perpendicular to the up and down directions, the hinged frame is a circular ring, an elliptical ring or a polygonal frame, and the polygonal frame includes a triangular frame, a square frame, a rectangular frame, a pentagonal frame, a hexagonal frame and an octagonal frame.

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

[0050] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0052] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0053] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, when describing pipelines or channels, the "connected" and "connected" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0054] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0055] Compared with traditional concrete buildings, steel structure buildings use metal materials such as steel plates or steel sections to replace reinforced concrete. They have the advantages of higher strength and better earthquake resistance. Since components of metal profiles such as steel plates and steel sections can be prefabricated in factories and installed on site, the construction period can be reduced. In addition, since metal materials can be reused, construction waste can be reduced and it is more environmentally friendly, so it is widely used in industrial and civil buildings.

[0056] In recent years, the tie rod suspension system has increasingly become the mainstream of steel structure systems in comprehensive building construction. Among them, between two adjacent layers of steel structures in the vertical direction, high-strength tie rods can be used for suspension support, so that the steel structure system can be used as the main supporting structure of the building through a larger span or structural strength. In this way, the support connection between the two adjacent layers of steel structures and the steel tie rods is a suspension structure system.

[0057] For example, the upper and lower ends of the tie rods in the tie rod suspension system can be connected and installed with the beams in the two adjacent layers through a hinged structure, such as a segmented fork ear connection installation method. Alternatively, the tie rod can also be an integral structure extending up and down (can be extended and connected through a sleeve), and its lower end can be supported by a structure such as a base, and in the process of the tie rod extending upward, it can be fixedly connected to the main bearing structure (i.e., beam) of the multi-story building, which is used for the support connection of multi-story beams in steel structure buildings, that is, an integral lower support connection installation method.

[0058] In the related technical solutions, such as Figure 1 As shown, Figure 1 Schematic diagram of a connection structure of 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 be provided with plug-in slots 04 at the ends close to the ear plates 02 for plugging and accommodating the ear plates 02. Subsequently, a hinge shaft 05 can be used to pass through the side wall of the plug-in slot 04 and the ear plate 02 so that the end of the tie rod 03 is hingedly installed with the ear plate 02, thereby realizing the arrangement and installation of the tie rod 03 in a segmented fork-ear connection manner.

[0059] However, since the tie rod 03 and the beam 01 are hingedly installed through the upper and lower ear plates 02, the connection between the beam 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 completely exposed on the upper and lower sides of the beam 01, which is not conducive to the stability setting of the hinge structure, and the exposed hinge structure will also affect the aesthetics of the steel structure building.

[0060] On the one hand, the present application provides a tie rod connection node 100, in order to solve the above problems, such as Figure 2 As shown, Figure 2 A schematic diagram of a three-dimensional structure of a tie rod connection node 100 provided in an embodiment of the present 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 example that the extending direction of the connecting beam 10 is a first straight line direction, the first straight line direction may be approximately parallel to the horizontal direction, may be a left-right direction, may be a front-to-back direction, and may have an angle with the front-to-back direction and the front-to-back direction, without limitation. Taking the first straight line direction as Figure 2 Taking the left and right directions as an example, the connecting beam 10 may be provided with a mounting cavity 11 with a through hole structure along the second linear direction (such as the vertical direction) for mounting the hinge assembly 20. The first linear direction and the second linear direction may be perpendicular to each other or may intersect each other, which is not limited.

[0061] Continue to refer to Figure 2 At least part of the structure of the hinge assembly 20 may be located in the mounting cavity 11. Figure 3 As shown, Figure 3 for Figure 2A schematic diagram of a connection structure of the hinge assembly 20 and the pin 30 is shown in FIG. The first through hole 21 may be provided on the side wall of the hinge assembly 20 located in the installation cavity 11. Correspondingly, the installation position and angle of the hinge assembly 20 may be adjusted so that the axis of the first through hole 21 may be approximately parallel to the third linear direction, and the third linear direction may be perpendicular to the first linear direction and the second linear direction, and the third linear direction may be the front-back direction as an example. The axis of the pin 30 may also be approximately parallel to the third linear direction, and the pin 30 may be inserted into the first through hole 21 along the third linear direction. At the same time, the axial ends of the pin 30 may be connected to the two corresponding side walls of the installation cavity 11 (i.e., the connecting beam at the side wall), so that the hinge assembly 20 may be hingedly installed with the connecting beam 10 through the pin 30. Based on this, the main body direction of the hinge assembly 20 may extend approximately in the up-down direction during installation, and the two pull rods 40 may 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 an upper pull rod 40 may be connected to the first end (ie, the upper end) of the hinge assembly 20 , and the upper end of a lower pull rod 40 may be connected to the second end (ie, the lower end) of the hinge assembly 20 .

[0062] In this way, the upper end of the upper tie rod 40 can be connected and installed with the upper crossbeam (or connecting beam) so that the upper crossbeam can bear the force at the tie rod connection node 100 of this layer. Correspondingly, the lower end of the lower tie rod 40 can be connected and installed with the lower crossbeam (or connecting beam) to bear the force of the lower crossbeam. Since the hinge assembly 20 is hingedly installed with the connecting beam 10 through the pin 30, the tie rod 40 connected with the connecting beam 10 through the hinge assembly 20 and the connecting beam 10 can bear a large force, which is beneficial to improve the overall stability of the steel structure building. Since the hinged part of the hinge assembly 20 is hidden and installed in the installation cavity 11 of the connecting beam 10, it is avoided that the protruding and exposed hinge structure is easily damaged or corroded. At the same time, the overall aesthetics of the steel structure building can be improved by less exposed hinge structure.

[0063] like Figure 4 As shown, Figure 4 for Figure 2A three-dimensional structural schematic diagram of the connecting beam 10 is shown in . The connecting beam 10 may include a first connecting section 12, a second connecting section 13 and a hinged frame 14. For example, the first connecting section 12, the hinged frame 14 and the second connecting section 13 may be connected in sequence from left to right, that is, the left end (i.e., the first end) of the hinged frame 14 may be connected to the first connecting section 12, and the right end (i.e., the second end) of the hinged frame 14 may be connected to the second connecting section 13. The connecting beam 10 may be an integrally formed structure, or may be fixedly connected by welding or other processes, and has a high structural strength. The hinged frame 14 may be provided with an installation cavity 11 along the up and down directions, for accommodating and hingedly installing the hinge assembly 20. In order to facilitate the plug-in installation of the pin shaft 30, two aligned hinge holes 15 can be provided on the two oppositely arranged side walls of the hinge frame 14 corresponding to the pin shaft 30 along the third straight line direction (such as the front-to-back direction), so that the two ends of the pin shaft 30 can be plugged into the two hinge holes 15 one by one, that is, one end of the pin shaft 30 can be inserted into one hinge hole 15 and connected to the hinge frame 14 for installation.

[0064] For example, the front end of the pin 30 can be plugged and installed with a hinge hole 15 on the front side, and the rear end of the pin 30 can be plugged and installed with a hinge hole 15 on the rear side. In the process of installing the hinge assembly 20 and the pin 30, a part of the structure of the hinge assembly 20 can be inserted into the installation cavity 11, and the first through hole 21 and the two hinge holes 15 are aligned in the front-to-back direction, and then the pin 30 can be inserted into a hinge hole 15, a first through hole 21 and a hinge hole 15 from front to back (or from back to front) in sequence, so that the hinge assembly 20 is hingedly installed with the hinge frame 14 through the pin 30 to limit the freedom of the hinge assembly 20 in the up-down and left-right directions.

[0065] It should be noted that in the above embodiments, Figure 4 As shown, the installation cavity 11 may be a through-hole structure with openings on both the upper and lower sides. 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 building (such as the upper hinge assembly), so that the tie rod 40 can bear the force of the steel structure of this layer through the above steel structure building. Correspondingly, the tie rod 40 on the lower side of the tie rod connection node 100 can be connected to the lower steel structure building, so that the tie rod connection node 100 can bear the force of the lower steel structure building through the tie rod 40 on the lower side.

[0066] In some other embodiments, the tie rod connection node 100 can also be used at the uppermost steel structure building. In this case, the tie rod connection node 100 can include a tie rod 40 located at the lower side, the upper end of the tie rod 40 can be connected to the lower end of the hinge assembly 20, and the lower end of the tie rod 40 can be connected to the upper end of the hinge assembly 20 in another tie rod connection node 100 at the lower layer.

[0067] Alternatively, the tie rod connection node 100 can also be used at the lowest steel structure building. In this case, the tie rod connection node 100 can include a tie rod 40 located on the upper side, the lower end of the tie rod 40 can be connected to the upper end of the hinge assembly 20, and the upper end of the tie rod 40 can be connected to the lower end of the hinge assembly 20 in another tie rod connection node 100 on the upper layer.

[0068] In the above two tie rod connection nodes 100 including only one tie rod 40, the installation cavity 11 can also be set as a corresponding blind hole structure. Exemplarily, for the tie rod connection node 100 of the uppermost layer, the installation cavity 11 at the hinge frame 14 can be a blind hole structure with an opening at the lower side, so as to prevent rainwater and other debris from entering the installation cavity 11 from the upper opening to corrode the hinge assembly 20 and the pin 30. For the tie rod connection node 100 of the lowermost layer, the installation cavity 11 at the hinge frame 14 can be a blind hole structure with an opening at the upper side, so that the installation cavity 11 and the hinge structure can be hidden downward, thereby preventing the hinge assembly 20 and the pin 30 from being exposed downward, which has a better hiding effect and aesthetics.

[0069] In the embodiment of the present application, the tie rod connection node 100 can be a building structure mainly composed of metal components, or can be made of other polymer materials with high structural strength. For the connecting beam 10, the connecting beam 10 can be formed by at least one profile. For example, the cross-sectional shape of the profile can include an I-shape, an H-shape, a rectangle, a groove shape, and a U-shape, etc. In addition, the profile can be one or more of metal or non-metal profiles, which is not limited.

[0070] It should be noted that, for the above-mentioned profile, it refers to the shape structure of the cross section of the connecting beam 10 in the direction perpendicular to the first straight line. Taking the first connecting section 12 as an example, the I-shaped profile means that the first connecting section 12 can include two flange plates arranged horizontally in the up-down direction, and the middle parts of the two flange plates are connected by a supporting web, and the supporting web can be arranged perpendicular to the front-to-back direction, and the upper edge is connected to an upper flange plate, and the lower edge can be connected to a lower flange plate. The connection position of the supporting web and the flange plate can be located in the middle of the flange plate in the front-to-back direction. When the widths of the upper flange plate and the lower flange plate in the front-to-back direction are inconsistent, the first connecting section 12 is the corresponding I-shaped profile.

[0071] When the widths of the upper flange plate and the lower flange plate in the front-to-back direction are the same, the first connecting section 12 is the corresponding H-shaped profile. If the supporting web is connected to the front or rear side of the upper flange plate and the lower flange plate in the front-to-back direction, the first connecting section 12 is the corresponding channel-shaped profile. If the supporting web of the channel-shaped profile is connected to the two flange plates through rounded corners, it is a U-shaped profile.

[0072] In addition, if the first connecting section 12 can include two flange plates spaced apart in the up-down direction and two supporting webs spaced apart in the front-to-back direction, the upper edges of the two supporting webs can be connected to the front and rear edges of the upper flange plate, and the lower edges of the two supporting webs can be connected to the front and rear edges of the lower flange plate, so that the first connecting section 12 can be a rectangular profile.

[0073] Under the condition of meeting the requirements of building structure design, the material of the above profile can be a metal material or a non-metal material that meets the structural strength. Preferably, steel can be widely used in various components of the above tie rod connection node 100 due to its advantages of high structural strength and low cost.

[0074] Continue to refer to Figure 4 For the connecting beam 10, the hinge frame 14 may be a frame-shaped structure on a cross section perpendicular to the up-down direction, for accommodating Figure 2 The hinge assembly 20 shown in the figure, and the hinge frame 14 may have two edges arranged opposite to each other in the front-to-back direction for connecting the two ends of the pin 30. Exemplarily, the hinge frame 14 may include a first bending section 141 and a second bending section 142, and the cross-sections of the first bending section 141 and the second bending section 142 may be one or more of an I-shaped, H-shaped, rectangular, groove-shaped and U-shaped shape. In the left-right direction, the first end (i.e., the left end) of the first bending section 141 and the first end (i.e., the left end) of the second bending section 142 may be connected to the right end of the first connecting section 12. Correspondingly, the second end (i.e., the right end) of the first bending section 141 and the second end (i.e., the right end) of the second bending section 142 may be connected to the left end of the second connecting section 13. Such as fixed connection by welding. The first bending section 141 and the second bending section 142 may be arranged along the front-to-back direction, and at least one of the first bending section 141 and the second bending section 142 may be bent away from the other along the front-to-back direction and spaced to form the installation cavity 11 .

[0075] For example, the first bending section 141 at the rear side can be bent backward, or the second bending section 142 at the front side can be bent forward. Alternatively, the first bending section 141 at the rear side can be bent backward, and the second bending section 142 at the front side can be bent forward. The installation cavity 11 can be formed between the first bending section 141 and the second bending section 142 along the front-to-back direction.

[0076] In the cross section perpendicular to the up-down direction, at least one of the first bending section 141 and the second bending section 142 may be an arc structure extending in the left-right direction. For example, the main body of the hinge frame 14 including the first bending section 141 and the second bending section 142 may be an arc structure such as a circular ring or an elliptical ring.

[0077] Alternatively, in a cross section perpendicular to the up-down direction, at least one of the first bending section 141 and the second bending section 142 may be a multi-section bending structure with an acute angle, a right angle or an obtuse angle. For example, the main body shape of the hinged frame 14 including the first bending section 141 and the second bending section 142 may be a polygonal frame structure, which may include a triangular frame, a square frame, a rectangular frame, a pentagonal frame, a hexagonal frame, an octagonal frame and the like.

[0078] For example, since the force of the hinge assembly 20 can act on the front and rear sides of the hinge frame 14 through the pin 30, the hinge frame 14 can be set to be an axially symmetrical or centrally symmetrical structure relative to one of the axes in the front and rear directions, so as to facilitate uniform force on the hinge frame 14.

[0079] It should be noted that in the embodiments of the present application, Figure 4 As an example, the hinged frame 14 having the mounting cavity 11 shown in the figure can have a cross-sectional shape perpendicular to the up-down direction, such as an arc, a circular ring, an elliptical ring or a multi-frame structure. And the corresponding hinged frame 14 can be formed by using one or more profiles having a cross-sectional shape of an I-shaped, H-shaped, rectangular, groove-shaped and U-shaped as the first bending section 141 and the second bending section 142.

[0080] like Figure 5 As shown, Figure 5 for Figure 2 A top view of the tie rod connection node 100 is shown. The first bending section 141 may include a third connecting section 1411, a first hinge section 1412 and a fourth connecting section 1413 connected in sequence. The third connecting section 1411 and the fourth connecting section 1413 may be located on a side (i.e., the front side) of the first hinge section 1412 close to the second bending section 142, and may be bent and connected to the left and right ends of the first hinge section 1412. Correspondingly, the second bending section 142 may include a fifth connecting section 1421, a second hinge section 1422 and a sixth connecting section 1423 connected in sequence. The fifth connecting section 1421 and the sixth connecting section 1423 may be located on a side (i.e., the rear side) of the second hinge section 1422 close to the first bending section 141, and may be bent and connected to the left and right ends of the second hinge section 1422. So that the installation cavity 11 can be formed between the first bending section 141 and the second bending section 142.

[0081] For example, Figure 5As shown, in a cross section parallel to the left-right direction and the front-back direction, the angles formed between the third connecting segment 1411 and the first hinged segment 1412, the fourth connecting segment 1413 and the first hinged segment 1412, the fifth connecting segment 1421 and the second hinged segment 1422, and the sixth connecting segment 1423 and the second hinged segment 1422 may be obtuse angles. Correspondingly, the left end of the third connecting segment 1411 and the left end of the fifth connecting segment 1421 may be connected to the right end of the first connecting segment 12, and the right end of the fourth connecting segment 1413 and the right end of the sixth connecting segment 1423 may be connected to the left end of the second connecting segment 13, so that the first connecting segment 12 and the second connecting segment 13 can be connected through the hinge frame 14 (as shown in FIG. Figure 4 As shown) bears the force at the hinge assembly 20. At this time, the angle formed between the third connecting segment 1411 and the fifth connecting segment 1421 can be an acute angle, a right angle or an obtuse angle, so that the installation cavity 11 is approximately a hexagonal structure symmetrical along the left and right directions in the cross section. The angle formed between the first connecting segment 12 and the third connecting segment 1411 (and the fifth connecting segment 1421) can be an obtuse angle. Correspondingly, the angle formed between the second connecting segment 13 and the fourth connecting segment 1413 (and the sixth connecting segment 1423) can also be an obtuse angle. So that the hinge frame 14 and the first connecting segment 12 and the second connecting segment 13 on the left and right sides can bear a large force in the left and right directions, and correspondingly, the structure of the first bending segment 141 and the second bending segment 142 can also bear a large force in the left and right directions. And it is convenient for the connection and installation (such as welding) of the hinge frame 14, the first connecting segment 12 and the second connecting segment 13.

[0082] In addition, in the cross section parallel to the left-right direction and the front-back direction, the angles formed between the third connecting segment 1411 and the first hinged segment 1412, the fourth connecting segment 1413 and the first hinged segment 1412, the fifth connecting segment 1421 and the second hinged segment 1422, and the sixth connecting segment 1423 and the second hinged segment 1422 can also be right angles. At this time, 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 vertically connected to the first connecting segment 12 on the left side of the connection. 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 vertically connected to the second connecting segment 13 on the right side of the connection. Thus, the installation cavity 11 with a cross-sectional shape that is approximately a rectangular or square structure is formed, and the structure is simple.

[0083] 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 hinged segment 1412, the fourth connecting segment 1413, the fifth connecting segment 1421, the second hinged segment 1422, and the sixth connecting segment 1423, when connecting and installing multiple adjacent components, multiple adjacent upper flange plates can be contacted and connected, multiple adjacent lower flange plates can be contacted and connected, and multiple adjacent supporting webs can be contacted and connected. For example, the above components can be fixedly connected through welding technology, so that the connecting beam 10 has a stable structure for bearing larger forces.

[0084] In some other embodiments, if the connecting beam 10 is made of a square or rectangular profile. Figure 6 As shown, at this time, a hole can be opened in the upper flange plate and the lower flange plate at the corresponding position along the up-down direction to form a blind hole or through hole structure installation cavity 11. That is, part of the connecting beam 10 near the installation cavity 11 can be regarded as a hinge frame to form an integral structure connecting beam 10 including the first connecting section 12, the hinge frame and the second connecting section 13, without the need to set up 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 installation cavity 11.

[0085] Exemplarily, the two supporting webs on the front and rear sides of the installation cavity 11 can serve as the front and rear side walls of the installation cavity 11, and are used to support 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 installation pin 30. In this case, the connecting beam 10 is equivalent to forming the installation cavity 11 and the corresponding hinge frame 14 structure through the opening arrangement on the basis of the whole square steel profile, and the square steel profiles on the left and right sides of the installation 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 thereto.

[0086] Or, if Figure 7 As shown, the connecting beam 10 may also be composed of two profiles spaced apart in the front-to-back direction. Alternatively, the connecting beam 10 may at least form a mounting cavity 11 in the middle for mounting the hinge assembly and the pin by two profiles spaced apart in the front-to-back direction. In this case, hinge holes 15 may be provided on the webs corresponding to the two profiles. It should be noted that, in this embodiment, the profiles constituting the connecting beam 10 may be any one or two of the profiles having a cross-sectional shape of an I-shaped, H-shaped, rectangular, groove-shaped, and U-shaped.

[0087] Exemplarily, 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 the four webs in the front-to-back direction, or can only penetrate the two webs close to the mounting cavity 11 to form two hinge holes 15, so as to form a mounting cavity 11 for installing the hinge assembly 20 and the pin shaft 30.

[0088] Alternatively, if the connecting beam 10 is composed of two I-shaped or H-shaped profiles spaced apart in the front-to-rear direction, the webs of the two profiles can be arranged perpendicular to the front-to-rear direction, and hinge holes 15 can be opened at positions corresponding to the two webs to form an installation cavity 11 for installing the hinge assembly 20 and the pin shaft 30.

[0089] Alternatively, if the connecting beam 10 is composed of two groove-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 positions corresponding to the two webs to form a mounting cavity 11 for mounting the hinge assembly 20 and the pin 30. In this example, since the webs of the profiles can be located at the front side or the rear side in the front-to-back direction, the webs of the two profiles can be close to each other in the front-to-back direction, which is beneficial to improve the stability of the connection with the pin 30 and the hinge assembly 20.

[0090] It should be noted that in the above example, two profiles are spaced apart in the front-to-back direction to form the connecting beam 10. Along the front-to-back direction, two reinforcements, such as profiles or plates extending along 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 a reinforcement located on the left side of the hinge hole 15 can be connected to the web and / or flange plates of the front and rear profiles, and the front and rear ends of another reinforcement located on the right side of the hinge hole 15 can also be connected to the web and / or flange plates of the front and rear profiles, so that the two reinforcements can form a stable frame structure (i.e., hinge frame 14) with part of the profile at the hinge hole 15, which is used to stabilize the connection pin 30 and the hinge assembly 20.

[0091] Among them, since there is no good force connection point when the pull rod 40 passes through the connecting beam 10 in the vertical direction, the hinge frame 14 and the pin 30 are hinged, while the connecting beam 10 and the pull rod are stably hinged, the above-mentioned hinge structure can also be hidden, thereby improving the aesthetics of the structure.

[0092] In addition, in the hinge frame 14, for at least two hinge holes 15 distributed along the third straight line direction, they can be opened on the hinge frame 14 or the support web corresponding to the hinge section, and while the two ends of the pin shaft 30 in the third straight line direction are plugged and installed, the two support webs arranged approximately perpendicular to the third straight line direction can stably load the force of the hinge assembly 20 acting on the connecting beam 10 through the pin shaft 30. In addition, it is also possible that the hinge holes are not required to be opened on the hinge frame 14, and the two ends of the pin shaft 30 are fixedly connected to the hinge frame 14 or the support web corresponding to the hinge section through a welding process, which can also meet the hinge assembly 20 and the hinge frame 14 through the pin shaft 30. Hinged installation.

[0093] In some embodiments, Figure 8 As shown, Figure 8 for Figure 5 A right side cross-sectional view of the tie rod connection node 100 is shown in FIG. The connecting beam 10 may also include two sleeves 16, which may be at least partially located in the mounting cavity 11 and connected to the two hinge holes 15 (such as Figure 4 14 , and one sleeve 16 can be arranged one by one with one 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. In this way, the two sleeves 16 can be used to plug and install the front and rear ends of the pin shaft 30, so that the front and rear ends of the pin shaft 30 can increase the effective contact area with the hinge frame 14 through the sleeves 16, thereby improving the stability of the plug-in installation of the pin shaft 30 and the hinge frame 14.

[0094] For example, the outer diameter of the sleeve 16 may be smaller than or equal to the inner diameter of the hinge hole 15. Figure 8 The sleeve 16 can be partially located in the installation cavity 11, and one end of the sleeve 16 can be inserted into a corresponding hinge hole 15 (such as Figure 4 As shown in FIG. 1 ), the sleeve 16 can be connected and installed with the hinge frame 14. The sleeve 16 can also be connected and fixed with the supporting web provided 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 the two sleeves 16 arranged in a front and rear interval, thereby realizing the hinged installation of the hinge assembly 20.

[0095] In addition, the inner diameter of the sleeve 16 can also be set equal to the inner diameter of the hinge hole 15, and can be slightly larger than the outer diameter of the pin 30. In this case, both sleeves 16 can be set in the installation cavity 11, and one end of one sleeve 16 can be set close to the side wall of one hinge hole 15, and the hinge hole 15 and the inner hole of the sleeve 16 are aligned. Then, the sleeve 16 and the supporting web with the hinge hole 15 can be fixedly connected by welding. Based on this, the outer diameter of the pin 30 can be slightly smaller than the inner diameter of the sleeve 16 and the hinge hole 15, and the front end and the rear end of the pin 30 can be inserted into a sleeve 16 and a hinge hole 15 in turn, so as to realize the hinged installation of the hinge assembly 20.

[0096] In order to prevent the pin 30 from sliding in the front-to-back direction and disengaging from the hinge frame 14, Figure 8 As shown, the connecting beam 10 may also include a plurality of limit members 17. Along the front-to-back direction, the pin 30 may be located between the plurality of limit members 17, the front end or the rear end of the pin 30 may be connected and installed with at least one limit member 17, and the hinge hole 15 may be located between the plurality of limit members 17 in the front-to-back direction. For example, one or more limit members 17 on the front side may be connected with the front end face of the pin 30 and located at the front side of a hinge hole 15 in the front. Correspondingly, one or more limit members 17 on the rear side may be connected with the rear end face of the pin 30 and located at the rear side of a hinge hole 15 in the rear. The outline size of the limit member 17 may be set to be larger than the inner diameter size of the hinge hole 15, so that the limit members 17 at both ends of the pin 30 can limit the freedom of the pin 30 in the front-to-back direction.

[0097] Exemplarily, the stopper 17 may be a sheet-like structure, provided with one or more through holes, and the end surface of the pin 30 may also be provided with a corresponding threaded hole, and the stopper 17 and the end surface of the pin 30 may be connected by bolts. Taking the stopper 17 as a circular sheet-like structure as an example, the diameter of the stopper 17 may be set to be larger than the inner diameter of the hinge hole 15, thereby limiting the freedom of the pin 30 in the front-to-back 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 stopper 17 may also be set to be larger than the inner diameter of the sleeve 16, which may also limit the freedom of the pin 30 in its axial direction.

[0098] It should be noted that, in the above embodiment, the diameter of the circular sheet-shaped stopper 17 can also be set to be at least one centimeter larger than the diameter of the pin 30, which can also limit the freedom of the pin 30 in its axial direction. In this way, the stopper structures at both ends of the pin 30 can have smaller structural dimensions, avoiding the protrusion setting at the hinge position, which is conducive to improving the decorative effect of the appearance of the tie rod connection node 100.

[0099] In some other embodiments, if the stopper 17 is a sheet-like structure or a rod-like structure, the stopper 17 and the end surface of the pin 30 can be installed by screws, and the diameter of the stopper 17 can be regarded as the length of the sheet-like structure or the rod-like structure. In addition, the stopper 17 can also be set as a nut structure, and corresponding external threads can be set at the front and rear ends of the pin 30, which can also limit the freedom of the pin 30 in its axial direction, and the structure is simple. This application does not limit this.

[0100] Based on this, continue to refer to Figure 8 The connecting beam 10 may further include a plurality of ribs 18, and each sleeve 16 may be connected to the hinge frame 14 through one or more ribs 18, so as to improve the connection rigidity and connection 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. Exemplarily, a plurality of ribs 18 may be disposed in the installation cavity 11, so as to prevent the exposure of the ribs 18 from affecting the appearance of the hinge frame 14.

[0101] Take two sleeves 16 corresponding to four ribs 18 as an example, Fig. 9 , Fig. 9 for Figure 8 A schematic diagram of the structure of one side of the installation cavity 11 of the hinge frame 14 is shown in FIG. A rib plate 18 can be installed on each of the upper and lower sides of a sleeve 16, and the two rib plates 18 can be arranged perpendicular to the front-to-back direction. One side edge of one rib plate 18 can be in contact with and connected to the outer side surface of the sleeve 16, the second side edge of the rib plate 18 can be in contact with and connected to the supporting web (such as the first hinge section 1412), and the third side edge of the rib plate 18 can be in contact with and connected to the adjacent upper flange plate or lower flange plate, so that the force borne by the sleeve 16 can be evenly distributed in the hinge frame 14 along the upper and lower directions through the two rib plates 18.

[0102] In addition, a rib plate 18 may be provided on the left and right sides of each sleeve 16, and at least two adjacent edges of the rib plate 18 may be connected to the outer side surface and the supporting web of the sleeve 16, which may also increase the connection strength between the sleeve 16 and the hinge frame 14. Exemplarily, the rib plate 18 may be connected and installed at any position in the four directions of the upper, lower, left and right of the sleeve 16 to improve the structural strength of the connection between the sleeve 16 and the hinge frame 14.

[0103] In some embodiments, Fig.10 As shown, Fig.10 for Figure 3An exploded structural schematic diagram of the hinge assembly 20 is shown in the figure. The hinge assembly 20 may include a hinge 22 and a bearing 23. At least part of the hinge 22 may be located in the installation cavity 11, and the part of the hinge 22 located in the installation cavity 11 may be provided with a first through hole 21. Take the example that the axial direction of the first through hole 21 is parallel to the front-to-back direction (i.e., the third straight line direction) during installation. The bearing 23 may be installed in the first through hole 21, such as the bearing 23 may be arranged approximately coaxially with the first through hole 21. And the pin 30 may be inserted and installed with the first through hole 21 along the front-to-back direction through the bearing 23, for the hinged installation of the hinge 22. Since the pin 30 and the side wall of the first through hole 21 can slide relative to each other, the arrangement of the bearing 23 is conducive to reducing the friction resistance between the pin 30 and the hinge 22, so as to reduce the wear degree of the pin 30.

[0104] Exemplarily, the bearing member 23 located in the first through hole 21 can be interference fit with the first through hole. So that the bearing member 23 can be installed in the first through hole 21 more stably. The bearing member 23 can be a rolling bearing such as a ball bearing or a roller bearing. Or, the bearing member 23 can also be a sliding bearing. Exemplarily, the bearing member 23 can be a relatively smooth sleeve located between the first through hole 21 and the pin 30, and lubricating oil can be used to reduce the friction resistance between the pin 30 and the side wall of the first through hole 21. In addition, it is also possible to not provide the bearing member 23, and only need to adjust the inner diameter of the first through hole 21 to be slightly larger than the outer diameter of the pin 30, and the pin 30 can also be inserted into the first through hole 21 along the front-to-back direction for the hinged installation of the hinge 22.

[0105] 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, after the pin 30 is inserted into the first through hole 21, there is a gap between the pin 30 and the first through hole 21 in the radial direction. If the pin 30 is plugged and installed with the first through hole 21 through the bearing member 23, the pin 30 can be inserted into the bearing member 23 along the axial direction and have an interference fit with the bearing member 23, and the bearing member 23 can also have an interference fit with the first through hole.

[0106] In some embodiments, the bearing member 23 is taken as an example of a spherical bearing (a type of sliding bearing). Fig.11 As shown, Fig.11 for Fig.10 The bearing member 23 is an exploded structural schematic diagram shown in FIG. The bearing member 23 may include an outer ring member 231 and an inner ring member 232, and the outer ring member 231 and the inner ring member 232 may both be annular structures. Fig.12 , Fig.13 and Fig.14 , Fig.12 for Fig.11 A cross-sectional view of the outer ring member 231 is shown in FIG. Fig.13 for Fig.11 A cross-sectional view of the inner ring member 232 shown in FIG. Fig.14 for Fig.11 A cross-sectional view of the outer ring member 231 and the inner ring member connected and installed is shown in. The outer ring member 231 can be set on 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 fit and slide in connection.

[0107] Based on this, combined Fig.15 , Fig.15 for Figure 8 A partial enlarged schematic diagram at A in the middle. The outer ring member 231 can be installed in the first through hole 21, such as the outer ring member 231 can be interference fit with the hinge member 22. At this time, the inner ring member 232 can be provided with a second through hole 233 along its axial direction, and the pin 30 can be inserted into the second through hole 233 along the front-back direction and hingedly installed with the hinge member 22. Based on this, for the joint bearing including the inner ring member 232 and the inner and outer ring members 231, the inner ring member 232 can not only rotate around its axis relative to the outer ring member 231, but also the inner ring member 232 can rotate around the center of the sphere of the outer ring member 231 in three-dimensional space, so that the axis of the inner ring member 232 can have an angle compared with the axis of the outer ring member 231. In this way, the angle adjustment range of the outer hinge member 22 compared with the connecting beam 10 or the pin 30 can be increased.

[0108] Exemplarily, 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 can swing relative to the axis of the pin 30 within the allowed spatial range, so that the upper and lower connected tie rods 40 can have a larger angle adjustment range, so that the hinged mounting component at the tie rod connection node 100 can absorb errors and have the effect of absorbing and offsetting internal stress.

[0109] In order to prevent the bearing member 23 installed in the first through hole 21 from being detached from the first through hole 21 along its axial direction, as shown in FIG. Fig.10 As shown, the hinge assembly 20 may further include a plurality of first positioning rings 24, and the plurality of first positioning rings 24 may be located in the installation cavity 11. Along the front-to-back 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 22 and connected to the hinge 22. Among them, the inner diameter of the first positioning ring 24 may be smaller than the outer diameter of the outer ring 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 231 (e.g., Fig.15Thus, by installing the first locating rings 24 aligned on the front and rear sides of the first through hole 21, it is convenient to insert and install the pin shaft 30, and it can also prevent the outer ring member 231 from being separated from the hinge member 22 along the front and rear directions from the two ends of the first through hole 21.

[0110] It should be noted that, for the spherical bearing, the installed outer ring 231 can limit the freedom of the inner ring 232 in the axial direction. For example, the outer ring 231 can be a two-ring structure that is detachable in the axial direction, used to form an inner spherical surface and a spherical chamber structure for slidingly installing the inner ring 232. In order to allow the inner ring 232 to stably deflect at multiple angles relative to the outer ring 231 relative to 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 set to have a larger width in the axial direction relative to the outer ring 231, such as the front end of the inner ring 232 can be set to protrude from the front end of the outer ring 231, and the rear end of the inner ring 232 can be set to protrude from the rear end of the outer ring 231.

[0111] For example, Fig.10 As shown, when the first positioning ring 24 and the hinge 22 are connected, the hinge 22 may be provided with a plurality of positioning holes 251 along the axial direction of the first through hole 21, and the plurality of positioning holes 251 may be distributed around the axis of the first through hole 21 at intervals on the outside of the first through hole 21 away from the axis. Correspondingly, the first positioning ring 24 may be provided with a plurality of connecting through holes 252. Fig.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 longer bolt or rivet or other connecting member can be used to axially pass through a connecting through hole 252, a positioning hole 251 and a connecting through hole 252 in sequence to squeeze the hinge 22 between the two first positioning rings 24.

[0112] In addition, the positioning hole 251 may also be a threaded hole of a blind hole structure, and may be arranged on both the front and rear sides of the hinge 22. Subsequently, a screw or bolt may be passed through a connecting through hole 252 and a positioning hole 251 in sequence to install a first positioning ring 24 on one side of the hinge 22, thereby limiting the axial freedom of the inner and outer ring members 231 of the first through hole 21. Alternatively, the first positioning ring 24 and the hinge 22 may be connected by welding or clamping, which is not limited.

[0113] In the above embodiment, along the axial direction of the outer ring member 231, if the width dimension of the outer ring member 231 is greater than or equal to the depth dimension of the first through hole 21, the outer ring member 231 can be squeezed and installed between the two first positioning rings 24 in the above manner. Even if the width dimension of the outer ring member 231 is slightly smaller than the depth dimension of the first through hole 21, the positioning and installation of the outer ring member 231 can still be relatively stable in the above manner, that is, the displacement of the outer ring member 231 in its axial direction is small.

[0114] In some other embodiments, continue to refer to Fig.10 The hinge assembly 20 may further include at least one second positioning ring 26. Fig.15 , the second positioning ring 26 can be installed in 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 extruded and installed between the outer ring 231 and the first positioning ring 24. In this way, by arranging one or more second positioning rings 26 on the front side and / or the rear side of the outer ring 231, the outer ring 231 can be extruded and installed between multiple first positioning rings 24 along the axial direction of the first through hole 21.

[0115] Exemplarily, the number of the first positioning rings 24 and the number of the second positioning rings 26 can both be two, and a second positioning ring 26 and a first positioning ring 24 can be sequentially arranged on the front side or the 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 one 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 area of ​​the first through hole 21.

[0116] 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. For example, 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, so as to avoid the setting of the first positioning ring 24 and the second positioning ring 26 affecting the deflection range of the inner ring 232 and the pin 30. In the plane perpendicular to the axial direction (such as along the up-down direction), the maximum inner diameter of the outer ring 231 is the inner diameter at its centroid, which can also be regarded as the spherical outer diameter of the inner ring 232. The minimum inner diameter of the outer ring 231 is the inner diameter of its front end or rear end in the up-down direction.

[0117] In some embodiments, Fig.10As shown, the hinge assembly 20 can be connected to the pull rod 40 (such as Figure 8 When the hinge 22 and the pull rod 40 are connected, the two components can be fixedly connected by welding, or the two components can be detachably connected by screw connection or the like.

[0118] For example, Figure 8 As shown, an external thread can be provided around the axial direction of the end of the pull rod 40 near the hinge assembly 20. Figure 8 and Fig.10 , corresponding threaded holes can be provided on the upper end surface and / or the lower end surface of the hinge 22. Then, one end of the pull rod 40 can be inserted into the threaded hole and the pull rod 40 or the hinge 22 can be rotated, so as to realize the detachable connection between the pull rod 40 and one end of the hinge 22. In addition, the hinge assembly 20 can also include a locking nut 27, which can be sleeved on the pull rod 40, and the locking nut 27 can be screwed in the direction close to the hinge 22, which is conducive to improving the connection strength between the pull rod 40 and the hinge 22. In addition, along the length direction of the pull rod 40, the outer diameter of the locking nut 27 can be gradually reduced in the direction away from the hinge 22, and the appearance is neat.

[0119] In some other embodiments, a sleeve with an internal thread may be provided at the end of the pull rod 40 , and corresponding external threads may be provided at the upper and lower ends of the hinge 22 , which can also be used for a detachable connection between the pull rod 40 and the hinge 22 .

[0120] On the other hand, the present application embodiment also provides a pull rod hanging building system 1000. Fig.16 As shown, Fig.16 A schematic structural diagram of a tie rod hanging building system 1000 provided in an embodiment of the present application. The tie rod hanging building system 1000 may include at least one tie rod connection node 100 as described above and a plurality of floor frames 200. Along the up and down direction (i.e., the second straight line direction), the plurality of floor frames 200 may be arranged at intervals, and at least two adjacent floor frames 200 may be hung and connected by one or more tie rod connection nodes 100. Exemplarily, each floor frame 200 may be formed by staggered connection of a plurality of beams 201. The plurality of beams 201 may be made of one or more profiles having a cross-sectional shape including an I-shaped, H-shaped, rectangular, trough-shaped, and U-shaped. Among them, the connecting beam 10 in the tie rod connection node 100 may also be regarded as a part of the structure of the beam 201, which is used to hinge the tie rod 40 to hang and support the floor frame 200.

[0121] In some embodiments, Fig.16As shown, at the two floor frames 200 on the upper and lower sides, the tie rod connection node 100 with the suspension rod 40 installed on one side can be hung and connected with the adjacent floor frame 200. For example, at the bottom floor frame 200, one or more tie rod connection nodes 100 can be installed at its crossbeam 201, and can be connected with the upper tie rod 40 through the upper end of the hinge 22, so that the upper floor frame 200 can hang and load the force of the vinegar floor frame 200.

[0122] In addition, among some floor frames 200 in the middle, each floor frame 200 can be connected to adjacent floor frames 200 by hanging through multiple tie rod connection nodes 100. Based on this, in the up and down direction, some cross beams 201 in the floor frames 200 in the middle can also be connected to adjacent floor frames 200 by hanging through the single-side tie rod connection nodes 100 of the upper or lower connection tie rods 40. Moreover, this structure is also applicable to the floor frame 200 at the bottom, and in this case, the corresponding installation cavity 11 can be set as a blind hole structure with an upper end opening.

[0123] In some embodiments, for the two floor frames 200 on the upper and lower sides, if part or all of the crossbeams 201 of the floor frame 200 are composed of square steel profiles. It is also possible to connect with the adjacent floor frame 200 by hanging without the above-mentioned tie rod connection node 100. Exemplarily, taking the crossbeam 201 in the upper floor frame 200 as an example, which includes a square steel profile, an aligned plug-in through hole can be opened on the upper flange plate and the lower flange plate of the crossbeam 201, and then the upper end of the tie rod 40 can be inserted into the plug-in through hole from bottom to top, and the upper end of the tie rod 40 can be exposed from the upper flange plate upward. Subsequently, the upper end of the tie rod 40 can be connected to the upper end of the tie rod 40 through a limiting hinge and a limiting nut, so that the limiting hinge can be located between the limiting nut and the upper flange plate, and the outline size of the limiting hinge can be larger than the outline size of the plug-in through hole, and the connection and installation of the tie rod 40 and the crossbeam 201 can also be achieved. In addition, the structural installation is also applicable to the middle floor frame 200 and the lower floor frame 200 formed by square steel, and there is no limitation on this.

[0124] It should be noted that in the related technical solution, when the tie rod is connected and installed through the lower support of the integral structure, if the tie rod is disconnected from one of the cross beams, the upper tie rod hanging system will fail and the structural stability will be poor. Moreover, during the maintenance of the tie rod hanging system installed in this way, it is necessary to support and fix the cross beams of all floors at the same time, which is relatively cumbersome. Through the above-mentioned improved setting of the present application, when using the above-mentioned tie rod connection node 100 to hang and connect multi-story steel structure buildings, multiple floor frames 200 can be connected to form an overall stable frame structure, and the overall force is safer. In addition, since the hinge assembly 20 is detachably connected to the connecting beam 10 and the tie rod 40, each floor frame 200 can be maintained by disassembly and installation, which is relatively convenient and will not affect the overall stability of the building.

[0125] Among them, through the design of the tie rod connection node 100, each floor frame is subjected to force independently without affecting each other. Even if part of the tie rod connection nodes 100 of one layer are damaged, the remaining floor frames are not affected. If an extreme natural disaster occurs and exceeds the design force limit, if the tie rod connection node 100 of a certain layer is damaged, the layer will be unstable, but the tension of the tie rod 40 at the floor frame on the upper floor frame will disappear, and the force on the tie rod 40 of the upper floor frame will be reduced, which indirectly protects the upper tie rod 40 from being damaged, making its upper floor frame structure safer.

[0126] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0127] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope described in the claims.
