Description

Technical Field

[0001] This utility model relates to the field of truss technology, and in particular to long-span truss assembly structures. Background Technology

[0002] A truss is a geometrically invariant structure composed of triangular frames made up of straight members. The connection points between the members are called nodes (or joints). Based on the axes of the truss members and the distribution of external forces, trusses can be divided into planar trusses and space trusses. Spatial structures such as roof trusses or bridges are composed of a series of parallel planar trusses. If they primarily bear planar loads, they can be simplified for calculation as planar trusses.

[0003] Existing trusses are usually integrated structures, which are formed by assembling trusses of different lengths to form a spatial structure. Long trusses are inconvenient to transport due to length limitations, and the bolts at the connection between trusses are subjected to high stress and are prone to damage. Therefore, long-span truss assembly structures are needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a long-span truss assembly structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a long-span truss assembly structure, including a first truss, a second truss, and a third truss. The first truss is arranged horizontally, the second truss is arranged vertically below one end of the first truss, and the third truss is arranged horizontally on the other end of the first truss. A first groove is formed on the bottom of one end of the first truss, and a first slider is slidably connected in the first groove. The bottom end of the first slider is hinged to the side end of the second truss by a first hinge. The bottom end of the first truss is connected to the top end of the second truss by a first bolt and a first nut. A second groove is formed on the bottom of the other end of the first truss, and a second slider is slidably connected in the second groove. The bottom end of the second slider is hinged to the bottom end of the third truss by a second hinge. The ends of the first truss and the ends of the third truss are connected by a second bolt and a second nut.

[0006] Preferably, the length of the first truss is greater than the sum of the lengths of the second and third trusses.

[0007] Preferably, the cross-sections of the first slide, the first slider, the second slide, and the second slider are all T-shaped with the same specifications.

[0008] Preferably, the first hinge and the first slider, the first hinge and the second truss, the second hinge and the second slider, and the second hinge and the third truss are all fastened together by screws.

[0009] Preferably, both the bottom end of the first truss and the top end of the second truss are provided with bottom through holes, and the threaded section of the first bolt passes through the bottom through hole and is threadedly connected to the first nut.

[0010] Preferably, a washer is fitted on the threaded section of the first bolt, and the washer is arranged between the bottom end of the first truss and the top end of the second truss.

[0011] Preferably, both the first truss and the third truss have end holes, and the threaded section of the second bolt passes through the end hole and is threadedly connected to the second nut.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the cooperation between the first slide groove, the first slider, and the first hinge enables the second truss to rotate and fold with the first truss. Conversely, the cooperation between the second slide groove, the second slider, and the second hinge enables the third truss to rotate and fold with the first truss. This effectively reduces the length of the long truss, minimizes space occupation, and facilitates transportation. At the same time, the connection of the second bolt and the second nut enables the longitudinal assembly of the first truss, the second truss, and the third truss.

[0014] In this invention, the connection between the first bolt and the first nut allows the second truss to be installed perpendicular to the first truss, thereby providing bottom support for the assembly of the first truss with other trusses. The second truss can also be used as a column structure. Furthermore, the second hinge provides bottom support at the bottom ends of the first and third trusses, which can effectively reduce bolt stress at the connection and prevent damage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 The long-span truss assembly structure includes a first truss 1, a second truss 2, and a third truss 3. The first truss 1 is arranged horizontally, the second truss 2 is arranged vertically below one end of the first truss 1, and the third truss 3 is arranged horizontally on the other end of the first truss 1. A first groove 4 is provided on the bottom of one end of the first truss 1, and a first slider 5 is slidably connected in the first groove 4. The bottom end of the first slider 5 is hinged to the side end of the second truss 2 by a first hinge 6. The bottom end of the first truss 1 and the top end of the second truss 2 are connected by a first bolt 7 and a first nut 8. A second groove 9 is provided on the bottom of the other end of the first truss 1, and a second slider 10 is slidably connected in the second groove 9. The bottom end of the second slider 10 is hinged to the bottom end of the third truss 3 by a second hinge 11. The ends of the first truss 1 and the ends of the third truss 3 are connected by a second bolt 12 and a second nut 13.

[0024] The cooperation between the first slide groove 4, the first slider 5, and the first hinge 6 enables the second truss 2 to rotate and fold with the first truss 1. Conversely, the cooperation between the second slide groove 9, the second slider 10, and the second hinge 11 enables the third truss 3 to rotate and fold with the first truss 1. This effectively reduces the length of the long truss, minimizes space occupation, and facilitates transportation. At the same time, the connection of the second bolt 12 and the second nut 13 enables the longitudinal assembly of the first truss 1, the second truss 2, and the third truss 3. The connection between the first bolt 7 and the first nut 8 allows the second truss 2 to be installed perpendicular to the first truss 1, thus providing bottom support for the assembly of the first truss 1 with other trusses. The second truss 2 can also be used as a column structure. Furthermore, the second hinge 11 provides bottom support at the bottom of the first truss 1 and the third truss 3, effectively reducing bolt stress at the connection and preventing damage.

[0025] Specifically, in this embodiment, the length of the first truss 1 is greater than the sum of the lengths of the second truss 2 and the third truss 3, so that the second truss 2 and the third truss 3 can be smoothly folded horizontally at the bottom of the first truss 1.

[0026] Specifically, in this embodiment, the cross-sections of the first slide 4, the first slider 5, the second slide 9, and the second slider 10 are all T-shaped with the same specifications, which ensures the sliding effect of the first slider 5 and the second slider 10, and at the same time improves the connection effect between the first slider 5 and the second slider 10 and the first truss 1, preventing separation.

[0027] Specifically, in this embodiment, the first hinge 6 and the first slider 5, the first hinge 6 and the second truss 2, the second hinge 11 and the second slider 10, and the second hinge 11 and the third truss 3 are all fastened together by screws 14, which realizes the detachable installation effect between the first hinge 6 and the first slider 5 and the second truss 2, as well as the detachable installation effect between the second hinge 11 and the second slider 10 and the third truss 3, thereby improving the support effect of the first hinge 6 and the second hinge 11.

[0028] Specifically, in this embodiment, a bottom through hole 15 is provided at the bottom end of the first truss 1 and the top end of the second truss 2. The threaded section of the first bolt 7 passes through the bottom through hole 15 and is threadedly connected to the first nut 8. The bottom through hole 15 is used for the insertion of the first bolt 7 during the assembly process between the first truss 1 and the vertically placed second truss 2 or third truss 3.

[0029] Specifically, in this embodiment, a washer 16 is fitted on the threaded section of the first bolt 7. The washer 16 is arranged between the bottom end of the first truss 1 and the top end of the second truss 2 to fill the gap between the first truss 1 and the second truss 2, ensuring the stable connection between the first bolt 7 and the first nut 8.

[0030] Specifically, in this embodiment, both the first truss 1 and the third truss 3 have end through holes 17. The threaded section of the second bolt 12 passes through the end through hole 17 and is threadedly connected to the second nut 13. The end through hole 17 is used for the insertion of the second bolt 12 during the assembly process between the first truss 1 and the horizontally placed third truss 3 or second truss 2.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
