Technical Field

[0001] This disclosure relates to the field of space frame structure technology, and in particular to a bolt ball reinforcement device and a space frame structure. Background Technology

[0002] Space frame structures, also known as shell structures, spatial structures, or grid shell structures, are widely used in large public buildings and major infrastructure projects such as stadiums, convention centers, and airport terminals due to their advantages such as reasonable stress distribution, beautiful appearance, strong spatial spanning capacity, and high degree of prefabrication in construction.

[0003] As the service life increases, the members and nodes of the space frame structure may experience problems such as loose connections and weakened cross sections due to environmental corrosion, fatigue loads, or insufficient maintenance. This can lead to a decrease in the load-bearing capacity of the nodes, a degradation of the overall structural performance of the space frame, and even affect the safety and durability of the space frame structure. Summary of the Invention

[0006] In some embodiments, the first ring body has a hole in its ring wall to form the through hole; or, the through hole is formed in the inner space of the first ring body.

[0007] In some embodiments, the radial direction of the first ring body is perpendicular to the radial direction of the second ring body, and the center of the first ring body coincides with the center of the second ring body, so as to define the fixed space within the first ring body and the second ring body.

[0008] In some embodiments, the first ring body includes: a first arc-shaped rod, a second arc-shaped rod, a first connecting structure, and a second connecting structure. The first end of the first arc-shaped rod and the first end of the second arc-shaped rod are detachably connected through the first connecting structure, and the second end of the first arc-shaped rod and the second end of the second arc-shaped rod are detachably connected through the second connecting structure. Wherein, when the first ring body and the second ring body are connected to form a ring, the first arc-shaped rod and the second arc-shaped rod are respectively cross-connected to two positions opposite to each other on the second ring body.

[0009] In some embodiments, the first end of the first arc-shaped rod is provided with a first connecting portion; the first end of the second arc-shaped rod is provided with a second connecting portion; the first connecting structure includes: a first screw and a second screw, the first screw passing through the first connecting portion and the second connecting portion and being threadedly connected to the first connecting portion and the second connecting portion, the second screw passing through the first connecting portion and the second connecting portion and being threadedly connected to the first connecting portion and the second connecting portion, and the first connecting portion, the second connecting portion, the first screw and the second screw cooperate to form the through hole.

[0010] In some embodiments, the radial directions of the first ring body and the second ring body are parallel and opposite to each other, thereby defining the fixed space between the first ring body and the second ring body.

[0011] In some embodiments, the fixing mechanism includes: a first part and a second part; the first part includes: a first connecting rod, a third arc-shaped rod, and a fourth arc-shaped rod, the third arc-shaped rod and the fourth arc-shaped rod being respectively connected to both ends of the first connecting rod; the second part includes: a second connecting rod, a fifth arc-shaped rod, and a sixth arc-shaped rod, the fifth arc-shaped rod and the sixth arc-shaped rod being respectively connected to both ends of the second connecting rod; wherein, the two ends of the third arc-shaped rod are detachably connected to the two ends of the fifth arc-shaped rod to form the first ring body, and the two ends of the fourth arc-shaped rod and the two ends of the sixth arc-shaped rod are detachably connected to form the second ring body.

[0012] In some embodiments, the adjustment mechanism includes two adjustment structures symmetrically arranged on both sides of the fixing mechanism; the adjustment structure includes a first connector, a third connector and a second connector, one end of the first connector is connected to the fixing mechanism, the other end of the first connector is connected to the third connector, and the second connector passes through the adjustment portion and the third connector and is movable relative to the adjustment portion and the third connector to adjust the distance between the adjustment portion and the third connector.

[0013] In some embodiments, the target through-hole is located between the two adjustment structures.

[0014] Secondly, this disclosure provides a space frame structure, which may include: a plurality of bolt balls, a plurality of bolt ball reinforcement devices as described in any one of the first aspects, a plurality of target rods and connecting ropes, each bolt ball having a plurality of threaded holes, each bolt ball being fixed in a fixed space of each bolt ball reinforcement device, each target rod having both ends passing through the through holes of two bolt ball reinforcement devices and being screwed to the threaded holes of the bolt balls in the corresponding fixed spaces, and both ends of the connecting rope being connected to the adjustment parts of the two bolt ball reinforcement devices.

The two ends of the connecting rope can be connected to the adjusting parts of the two bolt ball reinforcement devices. In this way, multiple bolt balls, multiple bolt ball reinforcement devices, multiple target rods, and multiple connecting ropes can be connected to form a space frame structure. The connecting rope can be kept taut by adjusting the adjusting part. In this way, if the connection between the two ends of the target rod and the corresponding threaded hole becomes loose or the cross section weakens due to environmental corrosion, fatigue load, or insufficient maintenance, the adjusting part can be moved closer to the center of the fixed space to further shorten the distance between the adjusting part and the node center, actively tensioning the connecting rope and keeping it in a high stress state. This ensures that the connection between the target rod and the bolt ball remains in a redundant bearing capacity even in abnormal situations such as connection failure or loosening, thereby improving the node stiffness and the safety and durability of the space frame structure.

It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, material composition, numerical expressions, and values ​​set forth in these embodiments should be interpreted as exemplary only and not as limiting.

[0033] It should be noted that, in the description of this disclosure, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientation or positional relationship, are only for the convenience of describing this disclosure 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, and therefore should not be construed as a limitation of this disclosure. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0034] Furthermore, the terms "first," "second," and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. "Vertical" is not strictly vertical, but within the permissible margin of error. "Parallel" is not strictly parallel, but within the permissible margin of error.

[0036] All terms used in this disclosure have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0037] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0038] Space frame structures, also known as shell structures, spatial structures, or grid shell structures, are widely used in large public buildings and major infrastructure projects such as stadiums, convention centers, and airport terminals due to their advantages such as reasonable stress distribution, beautiful appearance, strong spatial spanning capacity, and high degree of prefabrication in construction.

[0039] As the service life increases, the members and nodes of the space frame structure may experience problems such as loose connections and weakened cross sections due to environmental corrosion, fatigue loads, or insufficient maintenance. This can lead to a decrease in the load-bearing capacity of the nodes, a degradation of the overall structural performance of the space frame, and even affect the safety and durability of the space frame structure.

[0040] The inventors of this disclosure have discovered a bolt ball reinforcement device that can include a fixing mechanism and an adjusting mechanism. The fixing mechanism can be fitted over the outside of the bolt ball and has a through hole for target members such as chords or web members to pass through and connect to the threaded hole on the bolt ball within the fixing mechanism. Furthermore, in the extension direction of at least one target member, two bolt ball reinforcement devices are interconnected via an adjusting part of the adjusting mechanism using connecting ropes. This allows multiple bolt balls, multiple target members, multiple fixing mechanisms, multiple adjusting mechanisms, and multiple connecting ropes to collectively form a mesh-like grid structure. Each bolt ball and its corresponding bolt ball reinforcement device constitute a node in the grid structure. The adjusting part of the adjusting mechanism can move relative to the fixing mechanism along the extension direction of at least one target member, tauting the connecting rope connected to the adjusting part. This constrains the displacement between the two nodes connected to the target member, thereby enhancing the connection strength and load-bearing capacity of the node. Thus, by tautning the connecting rope, the relative movement between the bolt ball and the target member can be effectively limited, improving the overall stability of the node and enhancing the integrity, safety, and durability of the grid structure.

[0041] Here, chord members are the members located on the outermost layer or main boundary of the space frame structure. They are mainly set along the upper or lower edge of the space frame structure, forming the overall geometry of the space frame structure and constituting the "skeleton" or "outline" of the space frame structure. They can be divided into upper chord members and lower chord members. The upper chord members are located at the upper edge of the space frame structure, and the lower chord members are located at the lower edge of the space frame structure. Web members are internal diagonal or vertical members used to connect the upper and lower chord members. They are located "inside" the space frame structure. The chord members and web members can form a stable triangular force system to ensure the stability of the space frame structure.

[0042] First aspect

[0043] This disclosure provides a bolt ball reinforcement device 10, see [link]. Figures 1 to 11 The bolt ball reinforcement device 10 may include a fixing mechanism 11 and an adjusting mechanism 12. The fixing mechanism 11 may include a first ring 111 and a second ring 112, which are connected to define a spherical fixing space 113. The fixing mechanism 11 is provided with a plurality of through holes 114 connecting the fixing space 113 and the outer space of the fixing mechanism 11. The adjusting mechanism 12 is connected to the fixing mechanism 11 and has an adjusting part 121. The adjusting part 121 can move relative to the fixing mechanism 11 in a target direction to adjust the distance between the adjusting part 121 and the center of the fixing space 113. The target direction is parallel to the axis of the target through hole in the plurality of through holes 114. The through holes 114 are used to connect the target rod 20. The adjusting parts 121 of the two bolt ball reinforcement devices 10 can be connected by a connecting rope 30.

[0044] In the fixing mechanism 11, the first ring 111 and the second ring 112 can be as follows: Figures 3 to 5 The opposite intersecting connections shown can also be as follows: Figures 8 to 11 The relatively parallel connections of the first ring body 111 and the second ring body 112 can form an approximately spherical or spherical fixed space 113 after connection. The bolt ball 40, located in the fixed space 113, can abut against multiple positions of the first ring body 111 and the second ring body 112, so that the bolt ball 40 can be stably limited within the fixed space 113. The multiple through holes 114 provided in the fixing mechanism 11 respectively penetrate the fixed space 113 and the external space of the fixing mechanism 11, and the positions and angles of the multiple through holes 114 correspond to the axial directions of multiple target members 20 (such as web members 22, chord members 21, etc.) in the space frame structure 100, and allow the ends of the target members 20 to pass through the through holes 114 to establish a threaded connection with the threaded holes 401 on the bolt ball 40 in the fixed space 113.

[0045] In the adjustment mechanism 12, the adjustment mechanism 12 is detachably or fixedly connected to the fixing mechanism 11. The detachable connection allows the adjustment mechanism 12 to be separated from the fixing mechanism 11, and the detached adjustment mechanism 12 can be cleaned, repaired, or replaced. The adjustment mechanism 12 may be provided with one or more adjustment parts 121, each of which is configured to move relative to the fixing mechanism 11 in a target direction to adjust the distance between the center position of the adjustment part 121 and the fixed space 113 of the fixing mechanism 11, so that the movement path of the adjustment part 121 points towards or away from the geometric center of the fixed space 113. The target direction is parallel or substantially consistent with the depth direction of the target through holes 114, so that the length direction of at least one target rod 20 is parallel to the length direction of the connecting rope 30, and the connecting rope 30 can be taut when the adjustment part 121 moves closer to the geometric center of the fixed space 113.

[0046] Here, the two bolt ball reinforcement devices 10 respectively enclose and limit the two bolt balls 40 to form two nodes in the space frame structure 100. The two ends of the target rod 20 can pass through the target through holes of the two bolt ball reinforcement devices 10 respectively and connect with the corresponding threaded holes 401 to realize the reliable assembly of the target rod 20 and the node. Meanwhile, the two ends of a connecting rope 30 can be connected to the adjustment parts 121 of the two bolt ball reinforcement devices 10 respectively, forming a cross-node tensioning constraint system. In the event that the connection between the two ends of the target member 20 and the corresponding threaded hole 401 becomes loose or the cross section weakens due to environmental corrosion, fatigue load, or insufficient maintenance, the two ends of the connecting rope 30 remain effectively connected to the two adjustment parts 121, and can continue to bear part of the tension and limit the relative displacement between the nodes, thereby ensuring that the two nodes maintain the predetermined load-bearing capacity and structural integrity, and effectively preventing structural performance degradation. In addition, the distance between the adjustment part 121 and the node center can be further shortened by moving the adjustment part 121 closer to the center of the fixed space 113, and the connecting rope 30 can be actively tensioned to keep it in a high stress state, so that it still has redundant load-bearing capacity in the event of abnormal conditions such as connection failure or loosening between the target member 20 and the bolt ball 40, thereby improving the node stiffness and the safety and durability of the space frame structure 100.

[0047] In some embodiments, see Figures 3 to 5 The first annular body 111 has holes in its annular wall to form through holes 114; or, see Figures 8 to 11 The inner space of the first ring body 111 forms a through hole 114.

[0048] In other words, the through hole 114 can be a through hole set on the first ring body 111 independently outside the annular space of the first ring body 111, or it can be an opening in the center of the first ring body 111 itself. When the through hole 114 is a through hole set on the first ring body 111 independently outside the annular space of the first ring body 111, the through hole 114 can be formed on the side wall of the first ring body 111 by partial drilling or pre-setting a channel. For example, as described below, the through hole 114 is a through hole formed by the cooperation of the first connecting part 1115, the second connecting part 1116, the first screw 1117 and the second screw 1118.

[0049] In this embodiment, the through hole 114 can be disposed on the first ring body 111 and independently of the annular inner cavity of the first ring body 111, or it can be disposed within the annular inner cavity of the first ring body 111, allowing for flexible selection of its placement. Similarly, the through hole 114 can also be disposed on the second ring body 112 and independently of the annular inner cavity of the second ring body 112, or it can be disposed within the annular inner cavity of the second ring body 112, allowing for flexible selection of its placement.

[0050] In some embodiments, see Figures 1 to 6 The radial direction of the first ring 111 is perpendicular to the radial direction of the second ring 112, and the center of the first ring 111 and the center of the second ring 112 coincide, so as to define a fixed space 113 within the first ring 111 and the second ring 112.

[0051] The radial direction of the first ring 111 is the direction from the center of the first ring 111 to any point on the first ring 111; the radial direction of the second ring 112 is the direction from the center of the second ring 112 to any point on the second ring 112. The radial directions of the first ring 111 and the second ring 112 are perpendicular, and the centers of the first ring 111 and the second ring 112 coincide. That is, the first ring 111 and the second ring 112 are orthogonally arranged and concentric. For example, the first ring 111 is located in a horizontal plane, the second ring 112 is located in a vertical plane, and the centers of the first ring 111 and the second ring 112 coincide.

[0052] With the bolt ball 40 located in the fixed space 113, the bolt ball 40 can abut against the inner surfaces of the first ring body 111 and the second ring body 112.

[0053] In this embodiment, two orthogonal and concentric rings (i.e., the first ring 111 and the second ring 112) form a three-dimensional, enclosed fixed space 113 in the internal intersection area. This space is used to accommodate and cover the bolt ball 40, so as to realize multi-directional limiting of the bolt ball 40, thereby effectively preventing the bolt ball 40 from shifting or tilting when subjected to force, so as to affect the probability of the space frame structure 100.

[0054] In some embodiments, see Figures 3 to 6 The first ring body 111 may include: a first arc-shaped rod 1111, a second arc-shaped rod 1112, a first connecting structure 1113, and a second connecting structure 1114. The first end of the first arc-shaped rod 1111 and the first end of the second arc-shaped rod 1112 are detachably connected through the first connecting structure 1113, and the second end of the first arc-shaped rod 1111 and the second end of the second arc-shaped rod 1112 are detachably connected through the second connecting structure 1114. When the first ring body 111 and the second ring body 112 are connected to form a ring, the first arc-shaped rod 1111 and the second arc-shaped rod 1112 are respectively cross-connected to two opposite positions of the second ring body 112.

[0055] The first arc-shaped rod 1111 can be a half-ring, and the second arc-shaped rod 1112 can also be a half-ring. After the two ends of the first arc-shaped rod 1111 are connected to the two ends of the second arc-shaped rod 1112 through the first connecting structure 1113 and the second connecting structure 1114 respectively, a complete ring structure can be formed.

[0056] The first arc-shaped rod 1111 and the second arc-shaped rod 1112 are respectively cross-connected to two opposite positions on the second ring body 112. In this case, the cross-connection position can be a relatively fixed concave-convex fit. For example, at the cross-connection position of the first arc-shaped rod 1111 and the second ring body 112, the first arc-shaped rod 1111 is provided with a groove with open ends, and the second ring body 112 passes through the groove and abuts against the two opposite inner walls of the groove, so that the first ring body 111 and the second ring body 112 are relatively fixed after being connected, thereby enhancing the connection strength of the bolt ball reinforcement device 10 and the stability of the internal fixed space 113. Alternatively, the cross-connection position can be achieved by sequentially passing the first ring body 111 and the second ring body 112 through a rotating shaft, so that the first ring body 111 and the second ring body 112 can rotate relative to each other at the cross-connection position. The relative rotation setting can accommodate assembly errors, manufacturing errors, etc.

[0057] In this embodiment, the first ring body 111 is designed to be spliced ​​together by two arc-shaped rods (such as the first arc-shaped rod 1111 and the second arc-shaped rod 1112) through a detachable connection structure, and is cross-connected with the second ring body 112 in a relative position. This realizes the split assembly of the first ring body 111, which facilitates the installation, disassembly and maintenance of the bolt ball 40 on site. At the same time, the cross-fitting with the second ring body 112 also forms a fixing space 113 for limiting the bolt ball 40 within the first ring body 111 and the second ring body 112.

[0058] Here, the structure of the second ring body 112 may or may not be the same as the structure of the first ring body 111. For example, see [link to relevant documentation]. Figures 3 to 6 As shown, the structure of the second ring 112 is the same as that of the first ring 111, so that they can be mass-produced at the same time.

[0059] In some embodiments, see Figure 5 and Figure 6 The first arc-shaped rod 1111 has a first connecting part 1115 at its first end; the second arc-shaped rod 1112 has a second connecting part 1116 at its first end; the first connecting structure 1113 includes: a first screw 1117 and a second screw 1118, the first screw 1117 passes through the first connecting part 1115 and the second connecting part 1116 and is threadedly connected to the first connecting part 1115 and the second connecting part 1116, the second screw 1118 passes through the first connecting part 1115 and the second connecting part 1116 and is threadedly connected to the first connecting part 1115 and the second connecting part 1116, and the first connecting part 1115, the second connecting part 1116, the first screw 1117 and the second screw 1118 cooperate to form a through hole 114.

[0060] The extending direction of the first connecting portion 1115 may form an angle with the extending direction of the first arc-shaped rod 1111, and is partially located on one side of the first arc-shaped rod 1111 and partially located on the other side of the first arc-shaped rod 1111. Similarly, the extending direction of the second connecting portion 1116 may form an angle with the extending direction of the second arc-shaped rod 1112, and is partially located on one side of the second arc-shaped rod 1112 and partially located on the other side of the second arc-shaped rod 1112. The first connecting portion 1115 and the second connecting portion 1116 are arranged opposite to each other. The first screw 1117 can be screwed to the first connecting part 1115 and the second connecting part 1116 and is located on one side of the first ring body 111. The second screw 1118 can be screwed to the first connecting part 1115 and the second connecting part 1116 and is located on the other side of the first ring body 111. At the same time, there is a certain gap between the first screw 1117 and the second screw 1118 so that the first connecting part 1115, the second connecting part 1116, the first screw 1117 and the second screw 1118 cooperate to form a through hole 114.

[0061] Here, the outline shape of the through hole 114 formed by the cooperation of the first connecting part 1115, the second connecting part 1116, the first screw 1117, and the second screw 1118 can be adapted to the cross-sectional shape of the target rod 20 that is correspondingly inserted through the through hole 114. When the target rod 20 is inserted through the through hole 114, it can abut against the first connecting part 1115, the second connecting part 1116, the first screw 1117, and the second screw 1118 respectively, realizing multi-point contact limiting and significantly improving the connection stability between the target rod 20 and the bolt ball reinforcement device 10. For example, one end of the first connecting part 1115 extending in the direction of extension and one end of the second connecting part 1116 extending in the direction of extension can abut against each other. The first screw 1117 passes through the abutting position of the first connecting part 1115 and the second connecting part 1116, and the second screw 1118 passes through the non-abutting position of the first connecting part 1115 and the second connecting part 1116 and is parallel to the first screw 1117 to form a triangular through hole 114. The target rod 20 passing through the through hole 114 abuts against the first connecting part 1115, the second connecting part 1116 and the second screw 1118.

[0062] The first connecting structure 1113 may further include a first nut 1117A and a second nut 1118A. The first nut 1117A is located on the side of the second connecting part 1116 facing away from the first connecting part 1115 and is screwed to the first screw 1117. The second nut 1118A is located on the side of the second connecting part 1116 facing away from the first connecting part 1115 and is screwed to the second screw 1118. In this way, the axial pre-tightening and locking of the connection between the first connecting part 1115 and the second connecting part 1116 can be achieved through the cooperation of the first screw 1117 and the first nut 1117A, and the cooperation of the second screw 1118 and the second nut 1118A, effectively preventing the screw from loosening under vibration or load, and improving the overall connection rigidity and reliability of the first connecting structure 1113. At the same time, the screw-nut fastening method facilitates on-site assembly and disassembly, which is beneficial to the rapid installation and subsequent maintenance of the bolt ball reinforcement device 10.

[0063] In this embodiment, while achieving the split connection of the first ring body 111, a through hole 114 can be formed to facilitate the simultaneous assembly of the first ring body 111 to limit the bolt ball 40, and to simultaneously complete the insertion and positioning of the target rod 20. This design improves assembly efficiency.

[0064] In some embodiments, see Figure 6 The second connecting structure 1114 may include a third screw 1119 and a third nut 1119A. The third screw 1119 passes through the connecting part of the second end of the first arc-shaped rod 1111 and the connecting part of the second end of the second arc-shaped rod 1112, and is screwed to the third nut 1119A.

[0065] Among them, the first screw 1117, the second screw 1118 and the third screw 1119 can be parallel to each other, and the first screw 1117 can pass through the first connecting part 1115 and the second connecting part 1116 in sequence, the second screw 1118 can pass through the second connecting part 1116 and the first connecting part 1115 in sequence, and the third screw 1119 can pass through the connecting part of the second end of the first arc-shaped rod 1111 and the connecting part of the second end of the second arc-shaped rod 1112 in sequence. In this way, the connection method of the three screws in opposite directions can make the two ends of the first ring body 111 form a symmetrical and balanced distribution of fastening force, effectively avoiding structural distortion, eccentricity or local stress concentration caused by uneven force during the connection process.

[0066] In some embodiments, see Figures 8 to 11 The radial directions of the first ring 111 and the second ring 112 are parallel and opposite to each other, so as to define a fixed space 113 between the first ring 111 and the second ring 112.

[0067] The first ring 111 and the second ring 112 can be connected by a connecting rod (as described below, the first connecting rod 1151 and the second connecting rod 1161) to achieve the integrity of the bolt ball reinforcement device 10. When the radial directions of the first ring 111 and the second ring 112 are parallel and opposite to each other, a fixed space 113 that is approximately spherical or spherical can be formed between one side of the first ring 111 and one side of the second ring 112. When the bolt ball 40 is located in the fixed space 113, the two opposite sides of the bolt ball 40 can respectively abut against the annular surface of one side of the first ring 111 and the annular surface of one side of the second ring 112 to limit the bolt ball 40 within the fixed space 113.

[0068] In this design, a through hole 114 can be formed in the inner space of the first ring body 111, and a through hole 114 can also be formed in the inner space of the second ring body 112. This reduces the number of individually provided through holes 114 and improves the manufacturing efficiency of the bolt ball reinforcement device 10. Furthermore, multiple through holes 114 can be formed in the hollow area between the first ring body 111 and the second ring body 112, further reducing the number of individually provided through holes 114 and improving the manufacturing efficiency of the bolt ball reinforcement device 10.

[0069] In some embodiments, see Figures 9 to 11 The fixing mechanism 11 may include: a first part 115 and a second part 116; the first part 115 includes: a first connecting rod 1151, a third arc-shaped rod 1152 and a fourth arc-shaped rod 1153, the third arc-shaped rod 1152 and the fourth arc-shaped rod 1153 being connected to both ends of the first connecting rod 1151 respectively; the second part 116 includes: a second connecting rod 1161, a fifth arc-shaped rod 1162 and a sixth arc-shaped rod 1163, the fifth arc-shaped rod 1162 and the sixth arc-shaped rod 1163 being connected to both ends of the second connecting rod 1161 respectively; wherein, the two ends of the third arc-shaped rod 1152 and the two ends of the fifth arc-shaped rod 1162 are detachably connected to form a first ring body 111, and the two ends of the fourth arc-shaped rod 1153 and the two ends of the sixth arc-shaped rod 1163 are detachably connected to form a second ring body 112.

[0070] The first link 1151 and the second link 1161 can be straight or, as shown in the figure, they can be... Figures 9 to 11 The arc shape shown protrudes away from the fixed space 113; the detachable connection between the two ends of the third arc rod 1152 and the two ends of the fifth arc rod 1162 can refer to the connection configuration of the first arc rod 1111 and the second arc rod 1112. Similarly, the detachable connection between the two ends of the fourth arc rod 1153 and the two ends of the sixth arc rod 1163 can also refer to the connection configuration of the first arc rod 1111 and the second arc rod 1112, which will not be described again here.

[0071] In this embodiment, the detachable connection between the first part 115 and the second part 116 allows for separate assembly of the two parts, facilitating the assembly, maintenance, and replacement of the bolt ball 40.

[0072] In some embodiments, see Figure 1 , Figures 3 to 5 and Figures 8 to 10 The adjustment mechanism 12 includes two adjustment structures 122 symmetrically arranged on both sides of the fixed mechanism 11. The adjustment structure 122 includes a first connector 123, a third connector 124 and a second connector 125. One end of the first connector 123 is connected to the fixed mechanism 11, and the other end of the first connector 123 is connected to the third connector 124. The second connector 125 passes through the adjustment part 121 and the third connector 124 and can move relative to the adjustment part 121 and the third connector 124 to adjust the distance between the adjustment part 121 and the third connector 124.

[0073] Two adjusting structures 122 can be connected to the first arc-shaped rod 1111 and the second arc-shaped rod 1112 respectively. The first arc-shaped rod 1111 and the second arc-shaped rod 1112 can be provided with a first pin and a second pin that are opposite to each other. The first connecting member 123 can be a flexible steel wire rope, fiber rope, chain, etc. One end of the first connecting member 123 can be provided with a first sleeve hole 1231 and a second sleeve hole, and can be rotatably sleeved on the first pin and the second pin respectively. The other end of the first connecting member 123 can be connected to a third connecting part 124. The second connecting member 125 can be a screw that passes through the adjusting part 121 and the third connecting part 124, and can adjust the distance between the adjusting part 121 and the third connecting part 124 under the action of rotational force.

[0074] In this embodiment, the distance between the adjustment part 121 and the third connection part 124 can be adjusted by the second connector 125, which can tighten the connecting rope 30 between the two adjustment parts 121. In the case that the second connector 125 is a screw, the connecting rope 30 can be tightened by rotating the screw, which is simple and quick to operate.

[0075] The adjustment part 121 and the third connecting part 124 may each be provided with magnetic components so that they have an adsorption force on each other.

[0076] In some embodiments, see Figures 3 to 5 , Figures 8 to 10The target through-hole is located between the two adjustment structures 122. In this way, the target rod 20 (such as the web rod 22) through the target through-hole can be evenly subjected to the tension of the connecting ropes 30 on both sides to maintain the connection with the two bolt balls 40 at both ends of the target rod 20, thereby improving the node stiffness and the safety and durability of the space frame structure 100.

[0077] Second aspect

Figures 1 to 11 The space frame structure 100 may include: a plurality of bolt balls 40, a plurality of bolt ball reinforcing devices 10 according to any embodiment of the first aspect, a plurality of target rods 20, and a connecting rope 30. Each bolt ball 40 has a plurality of threaded holes 401. Each bolt ball reinforcing device 10 has a fixed space 113 for fixing a bolt ball 40. Both ends of each target rod 20 pass through the through holes 114 of two bolt ball reinforcing devices 10 and are screwed to the threaded holes 401 of the bolt balls 40 in the corresponding fixed space 113. Both ends of the connecting rope 30 are connected to the adjusting parts 121 of the two bolt ball reinforcing devices 10.

[0079] The connecting rope 30 can be a steel wire rope, a high-strength synthetic fiber rope, or a chain, etc. The two ends of the connecting rope 30 can be connected to the two adjusting parts 121 of the two bolt ball reinforcement devices 10 respectively, and a tension system is formed between the two adjusting parts 121. Then, when the position of the adjusting parts 121 is adjusted, the connecting rope 30 can be kept in a taut state. In this way, even in abnormal situations such as connection failure or loosening between the target rod 20 and the bolt ball 40, it still has redundant bearing capacity, thereby improving the node stiffness and the safety and durability of the space frame structure 100.
