Description

Technical Field

[0001] This utility model relates to the field of truss technology, and in particular to a truss gable roof ramp connection structure. Background Technology

[0002] A truss is a structure made up of members connected at both ends by hinges. It is typically a planar or longitudinal structure composed of straight members forming triangular units to accommodate axial tension or compression.

[0003] Utility model patent CN213477785U discloses a cantilever truss structure, including a top frame, a fixing groove, and a cable management plate. The top of the top frame is provided with an installation frame. The installation frame includes a sliding groove, and two sliding grooves are provided on the installation frame. Six sliding plates are slidably installed in these two sliding grooves. This solves the problem that after the existing truss is built into a stage, the lighting fixtures need to be fixed to the truss by bolts or wires, and the operation steps during installation and disassembly are relatively cumbersome.

[0004] However, among the aforementioned trusses, the cantilever beams (sloping beams) cannot be applied to different spans during installation, resulting in a limited range of applications; furthermore, the outer surface of the cantilever beams cannot form a uniform slope after installation, which is not conducive to the installation of subsequent structural components and leads to unsatisfactory performance. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems by providing a truss with different spans that can be applied to a wide range of applications. This structure can also ensure that the slope above the sloping top beam is uniform and has strong practicality.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a truss gable roof ramp connection structure, including a lower crossbeam and a support beam. The support beam is vertically fixed in the middle of the lower crossbeam and extends upward. An upper crossbeam is provided between the two sets of support beams. Inclined top beams are symmetrically provided on both sides of the support beam. One end of the inclined top beam is movably connected to the support beam through an upper inclined bracing mechanism, and the other end is movably connected to the lower crossbeam through a lower inclined bracing mechanism.

[0007] Preferably, the upper inclined support mechanism includes a fixed frame, one side of which is provided with an extension tube, and the end of the extension tube is provided with a first mounting protrusion, which is hinged to a first mounting cavity by a pin.

[0008] Preferably, the outer side of the fixed frame is fixedly connected to the end of the inclined top beam, and the end of the first assembly cavity is fixedly connected to the upper crossbeam.

[0009] Preferably, the lower inclined support mechanism includes a fixed frame and a movable frame. A connecting elbow is provided between the fixed frame and the movable frame. One end of the connecting elbow is fixedly connected to the movable frame, and the other end is provided with a second assembly cavity. The end of the fixed frame is provided with a second assembly protrusion that mates with the second assembly cavity. The second assembly protrusion and the second assembly cavity are hinged by a pin.

[0010] Preferably, the end of the movable frame is provided with a connecting frame, and the connecting frame is fixedly connected to the inclined top beam.

[0011] Preferably, the lower diagonal brace mechanism further includes a reinforcing diagonal brace, one end of which is fixedly connected to the connecting frame and the other end of which is fixedly connected to the movable frame.

[0012] Preferably, the second fixing frame is fixed to the surface of the lower crossbeam.

[0013] This utility model discloses a truss gable roof ramp connection structure, including a lower crossbeam and a support beam. The support beam is vertically fixed in the middle of the lower crossbeam and extends upward. An upper crossbeam is provided between the two sets of support beams. Sloping top beams are symmetrically provided on both sides of the support beam. One end of the sloping top beam is movably connected to the support beam through an upper inclined bracing mechanism, and the other end is movably connected to the lower crossbeam through a lower inclined bracing mechanism. Compared with the prior art, this truss gable roof ramp connection structure has the advantages of being applicable to trusses with different spans, having a wide range of applications, and ensuring a uniform slope on the top beam, thus having strong practicality.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Please refer to Figure 1-2 A truss gable roof ramp connection structure includes a lower crossbeam 1 and a support beam 2. The support beam 2 is vertically fixed in the middle of the lower crossbeam 1 and extends upward. An upper crossbeam 3 is provided between the two sets of support beams 2. The ends of the lower crossbeam 1 are all fixedly supported by vertical beams. Inclined top beams 4 are symmetrically provided on both sides of the support beam 2. One end of the inclined top beam 4 is movably connected to the support beam 2 through an upper inclined bracing mechanism 5, and the other end is movably connected to the lower crossbeam 1 through a lower inclined bracing mechanism 6. The height of the support beam 2 and the length of the inclined top beam 4 can be adjusted by adding or removing trusses.

[0025] In this embodiment, the truss as a whole includes four vertical beams (not shown in the figure), four lower horizontal beams 1 set at the same height, two opposing support beams 2, an upper horizontal beam 3 between the two support beams 2, and four inclined top beams 4, thus forming a house-shaped truss. Since the ends of the inclined top beams 4 are movably connected through the upper inclined bracing mechanism 5 and the lower inclined bracing mechanism 6, the lower inclined bracing mechanism 6 can be applied to different spans through the cooperation of the upper inclined bracing mechanism 5, with a wide range of applications. Moreover, the whole structure is easy to install and disassemble, and has strong practicality.

[0026] like Figure 2 As shown, when the length of the lower beam 1 increases (the span increases), the lower diagonal bracing mechanism 6 rotates upward at a certain angle along with the inclined top beam 4. At the same time, the splicing truss of the support beam 2 and the inclined top beam 4 increases in overall length to meet the needs of different spans. After installation, the upper diagonal bracing mechanism 5, the lower diagonal bracing mechanism 6 and the upper part of the inclined top beam 4 are on the same diagonal line, which facilitates the later installation of equipment.

[0027] Please refer to Figure 3-4Specifically, the upper inclined support mechanism 5 includes a fixed frame 51, an extension tube 52 extending from one side of the fixed frame 51, and a first mounting protrusion 53 at the end of the extension tube 52. The first mounting protrusion 53 is hinged to the first mounting cavity 54 by a pin. In addition, the outer side of the fixed frame 51 is fixedly connected to the end of the inclined top beam 4 by a buckle or bolt, and the end of the first mounting cavity 54 is fixedly connected to the upper crossbeam 3.

[0028] In other words, the inclined top beam 4 is hinged to the upper crossbeam 3 through the upper inclined bracing mechanism 5. After hinge, the inclined top beam 4 and the extension pipe 52 are on the same inclined plane, ensuring the overall aesthetics of the truss and facilitating the later installation of equipment.

[0029] Please refer to Figure 5-8 Specifically, the lower inclined support mechanism 6 includes a fixed frame 61 and a movable frame 62. A connecting elbow 63 is provided between the fixed frame 61 and the movable frame 62. One end of the connecting elbow 63 is fixedly connected to the movable frame 62, and the other end is provided with a second mounting cavity 631. The end of the fixed frame 61 is provided with a second mounting protrusion 611 that cooperates with the second mounting cavity 631. The second mounting protrusion 611 and the second mounting cavity 631 are hinged by a pin 632.

[0030] In addition, the end of the movable frame 62 is provided with a connecting frame 64. The connecting frame 64 and the inclined top beam 4 can be fixedly connected by bolts, buckles or other detachable structures. The second fixed frame 61 is fixed on the surface of the lower crossbeam 1. The second fixed frame 61 and the lower crossbeam 1 can be fixedly connected by bolts, buckles or other detachable structures.

[0031] Furthermore, the lower inclined bracing mechanism 6 also includes a reinforcing inclined bracing 65, one end of which is fixedly connected to the connecting frame 64 and the other end is fixedly connected to the movable frame 62, so as to improve the overall strength of the lower inclined bracing mechanism.

[0032] In this embodiment, both the upper inclined support mechanism 5 and the lower inclined support mechanism 6 are hinged by a column with a concave-convex fit, and their hinge structures are the same.

[0033] In use, the cooperation of the upper inclined bracing mechanism 5 and the lower inclined bracing mechanism 6 can be applied to truss structures with different spans. As the span changes, the height of the support beam 2 and the length of the inclined top beam 4 can be adjusted according to the requirements. In addition, when the span changes, the angle of the movable frame 62 in the lower inclined bracing mechanism 6 is adjusted accordingly. After the whole installation, the extension pipe 52, the inclined top beam 4 and the movable frame 62 are located on the same inclined plane, which not only ensures aesthetics but also facilitates the installation of equipment components later.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
