Description

Technical Field

[0001] This invention relates to the field of truss construction technology, specifically to a truss assembly structure and its assembly method. Background Technology

[0002] A truss is a triangular unit structure composed of members connected by hinges or welding. It primarily bears axial tensile or compressive forces and is characterized by material savings, light weight, and high stiffness. Based on materials, trusses can be classified into steel trusses, reinforced concrete trusses, prestressed concrete trusses, timber trusses, steel-timber composite trusses, and steel-concrete composite trusses. Space trusses use smooth spherical hinges at their nodes, requiring calculation of internal forces under three-dimensional equilibrium conditions. They are widely used in large-span buildings such as bridges, roofs, and stadiums.

[0003] For example, a truss assembly structure with publication number CN222862686U relates to the field of truss construction technology. It includes upper and lower chord groove members arranged correspondingly at the top and bottom. The two ends of the upper and lower chord groove members are supported by elastic supports, and the middle parts of the upper and lower chord groove members are supported by a water-shaped integrated support member. The elastic supports are fixedly connected to the upper and lower chord groove members. The water-shaped integrated support member is connected to the upper and lower chord groove members by a concave-convex interlocking connection. The elastic supports include an upper support rod threaded into the upper chord groove member, with an upper support spring fitted on the upper support rod; and two lower support rods threaded into the lower chord groove member, with lower support springs fitted on the lower support rods. The other ends of the upper and lower support rods overlap, and the overlapping part movably passes through a strip-shaped three-hole connecting block and is secured with a nut. The upper support rod is located between the two lower support rods. This utility model solves the problem of existing trusses protruding on one side, easily occupying structural space, and affecting the overall height of the truss.

[0004] While the aforementioned patented technology can provide effective planar support for the chord members, in practical applications, some truss structures need to achieve an arched distribution. This requirement for an arched distribution means that the truss must maintain a highly consistent geometric shape and stress characteristics in its overall structure. Therefore, during assembly and construction, in order to ensure that all components are accurately positioned and meet the design precision of the arched curve, the operational complexity and technical requirements are significantly increased, leading to a sharp increase in the overall construction difficulty.

[0005] Therefore, we propose a truss assembly structure and its assembly method to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a truss assembly structure and its assembly method to solve the problem mentioned in the background art of the inconvenience of arched assembly of trusses.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a truss assembly structure, comprising multiple chord mechanisms, a first support mechanism being provided between two upper and lower chord mechanisms, each chord mechanism including an upper chord, connecting mechanisms being provided at both ends of each chord mechanism, a second support mechanism being provided on one side of each chord mechanism, and an auxiliary mechanism being provided between two adjacent chord mechanisms; The auxiliary mechanism includes a first hinge plate disposed on one side of the upper chord, and a rectangular sleeve is fixedly installed at one end of the first hinge plate; One end of the auxiliary mechanism is provided with a sliding mechanism, which includes a rectangular slide rod that is slidably installed between the two rectangular sleeves.

The snap-fit ​​protrusion is located on one side of the snap-fit ​​hole. Bolt sleeves are fixedly installed at both ends of the upper chord.

[0009] Preferably, the first support mechanism includes a first support diagonal rod disposed on one side of the vertical rod, and corner bracket connectors are fixedly installed at the upper and lower ends of the first support diagonal rod. The corner bracket connectors are fixedly installed on the upper chord rod by first bolts.

[0010] Preferably, the connecting mechanism includes a second hinge plate disposed on one side of the bolt sleeve, one end of the second hinge plate is fixedly mounted with a guide post that is inserted and connected to the bolt sleeve, and the guide post is also provided with a connecting thread, which is threadedly connected to the bolt sleeve.

[0011] Preferably, the second support mechanism includes a second support diagonal rod, with straight connecting pieces fixedly installed at both ends of the second support diagonal rod. A plug-in piece is fixedly installed at one end of the straight connecting piece, and the plug-in piece passes through the snap-fit ​​hole and snaps into the snap-fit ​​protrusion.

[0012] Preferably, the upper end of the rectangular sleeve is provided with a first sliding groove, one end of the rectangular sleeve is provided with a groove opening, and the two sides of the rectangular sleeve are provided with second sliding grooves.

[0013] Preferably, sliders are fixedly installed at both ends of the rectangular slide rod, and the sliders are slidably installed inside the rectangular sleeve. Threaded rods are fixedly installed on the upper and lower sides of both ends of the rectangular slide rod, and the threaded rods are inserted into the first slide groove. A second bolt is threaded onto the upper end of the threaded rod.

[0014] Preferably, a fastening mechanism is provided on one side of the chord mechanism. The fastening mechanism includes a sleeve ring inserted through the upper chord. An inner angle bracket is fixedly installed on the inner wall of the sleeve ring. The inner angle bracket is installed on one side of the upper chord by a third bolt. A flexible band is installed between adjacent sleeve rings.

[0015] Preferably, a reversing mechanism is provided on one side of the auxiliary mechanism. The reversing mechanism includes a sliding sleeve that is slidably installed on one side of the rectangular sleeve. One end of the sliding sleeve is slidably connected to the rectangular sleeve by a fourth bolt. A flexible sheet is provided on one side of the sliding sleeve.

[0016] This invention also provides a truss assembly method, characterized by comprising the following steps: S1: Chord prefabrication: Weld the upper chord to the vertical bar to form a rectangular frame structure, weld bolt sleeves to both ends of the upper chord, and process side grooves and snap-fit ​​holes on the side end of the upper chord and weld snap-fit ​​protrusions. S2: Longitudinal chord connection: Connect the bolt sleeves of adjacent chord mechanisms to the guide column threaded connection. According to the design requirements of the truss planar or curved surface shape, adjust the rotation direction of the second hinge plate to the Y-axis or Z-axis position to complete the construction of the flexible node of the longitudinal chord. S3: Arch curvature adjustment: When constructing an arch or curved truss, loosen the second bolt, adjust the relative position of the rectangular slide bar in the rectangular sleeve along the first slide groove so that the spacing between adjacent chord members meets the design curvature requirements, tighten the second bolt to lock it, and install the first hinge plate with the side groove by hinge. S4: Spatial support system installation: Install the first support diagonal bar between the upper and lower chord mechanisms, and install the second support diagonal bar on the side of the chord mechanism, so that the plug-in piece and the snap-fit ​​protrusion engage to form a spatial cross support system; S5: Linear fine-tuning and fixing: Install the sleeve ring and the flexible band, and tension the flexible band to fine-tune and correct the arch line. When a reversing mechanism is provided, adjust the position of the sliding sleeve and fix the flexible sheet to complete the high-precision assembly of the curved truss.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. By using the sliding fit design of the rectangular slide bar and the rectangular sleeve in the sliding mechanism, the stepless adjustment of the spacing between adjacent chord mechanisms is realized. Combined with the hinge characteristics of the first hinge plate, the truss can flexibly adapt to the arch design requirements of different curvature radii during the assembly process. This effectively solves the problem of difficult arch line control caused by rigid connection of nodes in traditional truss assembly and significantly reduces the construction difficulty of arch trusses.

[0018] 2. After the arch alignment is adjusted to the correct position, the first and second support mechanisms provide double support to the truss structure from the vertical plane and the side, respectively. The first and second support diagonal members form a spatial cross support system, which effectively resists the thrust and bending moment generated by the arch structure under its own weight and external loads. The ductile band in the fastening mechanism applies continuous elastic constraints to the overall alignment of the arch truss through the transmission effect of the sleeve ring, eliminating local assembly errors and ensuring that the arch axis is highly consistent with the design curve.

[0019] 3. By combining modular prefabrication with on-site flexible adjustment, the rigid positioning process in traditional truss assembly is transformed into a reversible, gradual adjustment process, which significantly reduces the on-site construction difficulty and precision control cost of large space trusses. It is suitable for the construction of structural systems for large-span public buildings such as stadiums, convention centers, and airport terminals. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figures 1-7 A truss assembly structure includes multiple chord mechanisms 1, with a first support mechanism 2 shared between upper and lower chord mechanisms 1. Each chord mechanism 1 includes an upper chord 11, and connecting mechanisms 3 are provided at both ends of each chord mechanism 1. A second support mechanism 4 is provided on one side of each chord mechanism 1, and an auxiliary mechanism 5 is also provided between adjacent chord mechanisms 1.

[0024] A vertical rod 12 is installed between the two upper and lower chord rods 11. A side groove 13 is provided on the side end of the upper chord rod 11. A snap-fit ​​hole 14 is also provided on both sides of one end of the upper chord rod 11. A snap-fit ​​protrusion 15 is also fixedly installed on the side end of the upper chord rod 11. The snap-fit ​​protrusion 15 is located on one side of the snap-fit ​​hole 14. Bolt sleeves 16 are fixedly installed at both ends of the upper chord rod 11.

[0025] The connecting mechanism 3 includes a second hinge plate 31 disposed on one side of the bolt sleeve 16. One end of the second hinge plate 31 is fixedly installed with a guide post 32 that is inserted and connected to the bolt sleeve 16. The guide post 32 is also provided with a connecting thread 33, which is threadedly connected to the bolt sleeve 16.

[0026] During the assembly of the truss, the upper and lower chord members 11 are initially positioned by the vertical members 12 and welded together to form a rectangular frame of the basic chord mechanism 1. Bolt sleeves 16 are installed at both ends of the upper chord members 11, and the guide post 32 of the second hinge plate 31 is aligned with the bolt sleeve 16 for pre-insertion. By rotating the guide post 32, the connecting thread 33 and the bolt sleeve 16 form a threaded engagement, completing the construction of the flexible connection node between adjacent chord mechanisms 1. The two adjacent guide posts 32 are connected by the second hinge plate 31. When the second hinge plate 31 is set at the lower end of the chord mechanism 1, the rotation direction of the second hinge plate 31 is set on the Y-axis. The adjacent chord mechanism 1 is built as the side of the truss, which facilitates the construction of the arched truss.

[0027] When the threaded connection 33 rotates past the bolt sleeve 16, the guide post 32 and the bolt sleeve 16 can rotate in all directions, so that the rectangular frame can be adjusted in all four directions. When the second hinge plate 31 rotates to be parallel to the rectangular frame, the rotation direction of the second hinge plate 31 is set on the Z-axis, and the adjacent chord mechanism 1 is used as the top surface of the truss for construction.

[0028] The truss system is highly flexible and adaptable in design, and can be dynamically adjusted according to the specific shape and space size required in the actual application scenario. This adjustable feature not only expands the diversity of its structural combinations, but also provides more possibilities for splicing and connecting multiple truss segments, thereby enhancing the applicability and construction efficiency of the overall structure.

[0029] The auxiliary mechanism 5 includes a first hinge plate 51 disposed on one side of the upper chord 11, and a rectangular sleeve 52 is fixedly installed at one end of the first hinge plate 51. One end of the auxiliary mechanism 5 is provided with a sliding mechanism 6, which includes a rectangular slide rod 61 that is slidably installed between two rectangular sleeves 52.

[0030] When the rotation direction of the second hinge plate 31 is set on the Y-axis, and the adjacent chord mechanism 1 is built as the side of the truss, the relative position of the rectangular slide rod 61 of the sliding mechanism 6 in the rectangular sleeve 52 is adjusted according to the curvature radius requirement of the designed arch curve: First, loosen the second bolt 64, push the threaded rod 63 along the direction of the first slide groove 53, so that the slider 62 slides inside the rectangular sleeve 52, thereby changing the distance between the adjacent rectangular sleeves 52; when the chord spacing corresponding to the designed arch curvature is reached, tighten the second bolt 64 to lock and fix the rectangular slide rod 61 and the rectangular sleeve 52; then, the first hinge plate 51 and the side groove 13 of the upper chord 11 are hinged and installed so that the auxiliary mechanism 5 forms a connection system that can adapt to the arch deformation.

[0031] Through the sliding engagement design of the rectangular slide bar 61 and the rectangular sleeve 52 in the sliding mechanism 6, the stepless adjustment of the distance between adjacent chord mechanisms 1 is realized. Combined with the hinge characteristics of the first hinge plate 51, the truss can flexibly adapt to the arch design requirements of different curvature radii during the assembly process, effectively solving the problem of arch line control difficulties caused by rigid node connections in traditional truss assembly, and significantly reducing the construction difficulty of arch trusses.

[0032] Example 2: Please refer to Figures 1-6 The first support mechanism 2 includes a first support diagonal rod 21 disposed on one side of the vertical rod 12. Angle bracket connectors 22 are fixedly installed at the upper and lower ends of the first support diagonal rod 21. The angle bracket connectors 22 are fixedly installed on the upper chord rod 11 by the first bolts 23. The first support mechanism 2 is installed between the upper and lower chord rod mechanisms 1: the angle bracket connectors 22 at both ends of the first support diagonal rod 21 are fixed to the corresponding positions of the upper chord rod 11 by the first bolts 23 to form an oblique support in the vertical plane.

[0033] The second support mechanism 4 includes a second support diagonal rod 41. Straight piece connectors 42 are fixedly installed at both ends of the second support diagonal rod 41. A plug-in piece 43 is fixedly installed at one end of the straight piece connector 42. The plug-in piece 43 passes through the snap-fit ​​hole 14 and snaps into the snap-fit ​​protrusion 15.

[0034] Insert the plug-in piece 43 at the end of the second support diagonal rod 41 into the snap-fit ​​hole 14 and engage with the snap-fit ​​protrusion 15. The straight piece connector 42 fits against the side wall of the upper chord rod 11 to complete the lateral support construction and fix the two opposing rectangular frames.

[0035] A fastening mechanism 7 is provided on one side of the chord mechanism 1. The fastening mechanism 7 includes a sleeve ring 71 inserted on the upper chord 11. An inner corner bracket 72 is fixedly installed on the inner wall of the sleeve ring 71. The inner corner bracket 72 is installed on one side of the upper chord 11 by a third bolt 73. A flexible band 74 is installed between adjacent sleeve rings 71.

[0036] After the second support mechanism 4 is installed, the sleeve ring 71 is sleeved on the outside of the upper chord 11. The sleeve ring 71 abuts against one end of the straight plate connector 42 to fix the second support diagonal rod 41. Finally, the inner angle bracket 72 is fixed by the third bolt 73, and the toughness band 74 is tensioned between adjacent sleeve rings 71. The prestress of the toughness band 74 is used to fine-tune and correct the overall shape of the arch truss, and the high-precision assembly of the arch truss is completed.

[0037] After the arch alignment is adjusted to the correct position, the first support mechanism 2 and the second support mechanism 4 provide dual support to the truss structure from the vertical plane and the side, respectively. The first support diagonal rod 21 and the second support diagonal rod 41 form a spatial cross support system, which effectively resists the thrust and bending moment generated by the arch structure under its own weight and external loads. The ductile band 74 in the fastening mechanism 7 applies continuous elastic constraints to the overall alignment of the arch truss through the transmission effect of the sleeve ring 71, eliminates local assembly errors, and ensures that the arch axis is highly consistent with the design curve.

[0038] Example 3: Please refer to Figures 1-9 The upper end of the rectangular sleeve 52 is provided with a first sliding groove 53, one end of the rectangular sleeve 52 is provided with a groove 54, and the two sides of the rectangular sleeve 52 are provided with a second sliding groove 55.

[0039] Slider 62 is fixedly installed at both ends of the rectangular slide rod 61. The slider 62 is located inside the rectangular sleeve 52, and its diagonal length is less than the width of the rectangular sleeve 52. Threaded rods 63 are fixedly installed on the upper and lower sides of both ends of the rectangular slide rod 61. The threaded rods 63 are inserted and connected to the first slide groove 53. The upper end of the threaded rod 63 is threaded with a second bolt 64.

[0040] When the rotation direction of the second hinge plate 31 is set on the Y-axis, the threaded rod 63 of the rectangular slide bar 61 slides in the first slide groove 53 until the angle adjustment of the truss is completed. Finally, the angle of the truss can be fixed by tightening the second bolt 64.

[0041] When the rotation direction of the second hinge plate 31 is set on the Z-axis, loosen the second bolt 64 and slide the rectangular slide bar 61 to its longest length. The slider 62 is located in the groove 54. At this time, rotate the rectangular slide bar 61, and the adjacent rectangular frames can rotate about the Z-axis. One end of the rectangular slide bar 61 is located in the groove 54. After it is adjusted to a suitable angle, tighten the second bolt 64 to fix it.

[0042] A reversing mechanism 8 is provided on one side of the auxiliary mechanism 5. The reversing mechanism 8 includes a sliding sleeve 81 that is slidably installed on one side of the rectangular sleeve 52. One end of the sliding sleeve 81 is slidably connected to the rectangular sleeve 52 by a fourth bolt 82. A flexible sheet 83 is provided on one side of the sliding sleeve 81.

[0043] The inner wall of the sliding sleeve 81 and the outer wall of the rectangular sleeve 52 form a sliding fit relationship. A through groove corresponding to the second sliding groove 55 is opened on one side of the sliding sleeve 81. The fourth bolt 82 passes through the through groove and the second sliding groove 55 to realize the sliding lock between the sliding sleeve 81 and the rectangular sleeve 52. The flexible sheet 83 is made of high-strength rubber or polyurethane elastomer material. One end of the flexible sheet 83 is vulcanized to the outer wall of the sliding sleeve 81, and the other end of the flexible sheet 83 extends outward to form a free cantilever end. When the rotation direction of the second hinge plate 31 is set on the Z-axis, the flexible sheet 83 bends adaptively to increase the strength of the rectangular frame.

[0044] When the truss assembly structure is applied to the support system of large-span arched roofs or curved curtain walls, the reversing mechanism 8 and the auxiliary mechanism 5 work together to achieve multi-dimensional form adaptation: First, according to the torsion angle requirements of the designed curved surface, the position of the sliding sleeve 81 is adjusted along the axial direction of the rectangular sleeve 52 so that the cantilever end of the flexible piece 83 points to the predetermined connection position of the adjacent chord mechanism 1, and the fourth bolt 82 is tightened to complete the positioning of the sliding sleeve 81; then the free end of the flexible piece 83 is bolted or welded to the corresponding connecting parts of the adjacent truss unit, and the elastic deformation capability of the flexible piece 83 is used to absorb the relative torsional displacement between the adjacent chord mechanisms 1.

[0045] During the assembly of the curved truss, the first hinge plate 51 provides rotational freedom about the horizontal axis, the sliding mechanism 6 provides telescopic adjustment capability along the longitudinal direction of the truss, and the reversing mechanism 8 provides torsional adaptability about the longitudinal axis through the elastic deformation of the flexible plate 83. Together, the three constitute a flexible connection node that is adjustable in three directions in space. This node design enables the truss system to adapt to the anisotropic deformation coordination requirements in complex curved shapes while maintaining the continuity of the overall structure, avoiding the problem of residual stress concentration caused by forced assembly in traditional rigid nodes during curved assembly.

[0046] The present invention also provides a truss assembly method, which uses the above-mentioned truss assembly structure and includes the following steps: S1: Prefabrication of chord members: Weld the upper chord member 11 and the vertical member 12 to form a rectangular frame structure. Weld bolt sleeves 16 at both ends of the upper chord member 11. Process side grooves 13 and snap-fit ​​holes 14 on the side end of the upper chord member 11 and weld snap-fit ​​protrusions 15. S2: Longitudinal chord connection: Connect the bolt sleeve 16 of the adjacent chord mechanism 1 to the guide column 32 by thread. According to the design requirements of the truss planar or curved surface shape, adjust the rotation direction of the second hinge plate 31 to the Y-axis or Z-axis position to complete the construction of the flexible node of the longitudinal chord. S3: Arch curvature adjustment: When constructing an arch or curved truss, loosen the second bolt 64, adjust the relative position of the rectangular slide bar 61 in the rectangular sleeve 52 along the first slide groove 53 so that the spacing between adjacent chord mechanisms 1 meets the design curvature requirements, tighten the second bolt 64 to lock it, and hinge the first hinge plate 51 to the side groove 13. S4: Spatial support system installation: Install the first support diagonal bar 21 between the upper and lower chord mechanism 1, and install the second support diagonal bar 41 on the side of the chord mechanism 1, so that the plug-in piece 43 and the snap-fit ​​protrusion 15 are snap-fitted together to form a spatial cross support system. S5: Fine-tuning and fixing of the line: Install the sleeve ring 71 and the flexible band 74, and tension the flexible band 74 to fine-tune and correct the arch line. When the reversing mechanism 8 is provided, adjust the position of the sliding sleeve 81 and fix the flexible plate 83 to complete the high-precision assembly of the curved truss.

[0047] This method combines modular prefabrication with on-site flexible adjustment, transforming the rigid positioning process in traditional truss assembly into a reversible, gradual adjustment process. This significantly reduces the on-site construction difficulty and precision control costs of large spatial trusses, and is suitable for the construction of structural systems for large-span public buildings such as stadiums, convention centers, and airport terminals.

According to the design requirements of the truss plane or curved surface, adjust the rotation direction of the second hinge plate (31) to the Y-axis or Z-axis position to complete the construction of the flexible node of the longitudinal chord. S3: Arch curvature adjustment: When constructing an arch or curved truss, loosen the second bolt (64), adjust the relative position of the rectangular slide bar (61) in the rectangular sleeve (52) along the first slide groove (53) so that the spacing of the adjacent chord mechanism (1) meets the design curvature requirements, tighten the second bolt (64) to lock it, and hinge the first hinge plate (51) to the side groove (13); S4: Spatial support system installation: Install the first support diagonal rod (21) between the upper and lower chord mechanism (1), and install the second support diagonal rod (41) on the side of the chord mechanism (1) so that the plug-in piece (43) and the snap-fit ​​protrusion (15) are snap-fitted together to form a spatial cross support system; S5: Fine-tuning and fixing of the line: Install the sleeve ring (71) and the ductile band (74), tension the ductile band (74) to fine-tune and correct the arch line. When the reversing mechanism (8) is provided, adjust the position of the sliding sleeve (81) and fix the flexible sheet (83) to complete the high-precision assembly of the curved truss.
