Description

Technical Field

[0001] This utility model belongs to the field of space frame structure technology, specifically relating to a purlin support structure that is easy to assemble. Background Technology

[0002] Offshore photovoltaic grid structures have extremely tight construction schedules. Existing technologies present significant challenges in connecting the steel roof structure to the purlins, and this connection is a crucial factor determining the final quality of the metal roof.

[0003] The existing construction method for connecting purlins in steel structure roofs mostly involves setting purlin brackets at different locations according to the drawings, and fixing the purlins to the purlin brackets. This structure serves both to fix and connect multiple purlins and to connect the multiple purlin connection structure to the steel structure roof.

[0004] In the existing technology, considering that the bolt balls are of different sizes, there is a height difference at the highest point of the bolt ball surface. If purlins of the same specification are used, the purlins will also have a height difference, which will cause the purlins to be unable to be installed horizontally and the space frame installation to be completed. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and provide a purlin support structure that is easy to assemble, so that the purlin support unit can be detachably connected to the bolt ball, and the support of different lengths can be adjusted according to the size of the bolt ball, so that the uprights in the purlin support unit are at the same height, ensuring that the purlins are installed horizontally and ensuring the normal installation of the subsequent space frame.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A purlin support structure for easy assembly includes two bolt balls with a connecting rod fixed between them. The structure is characterized by further including a purlin support unit mounted on the bolt balls. Each purlin support unit includes a support, a base plate, and a vertical plate. The bolt balls have threaded holes, and a threaded rod is fixed to the bottom of the support, threadedly connected to the threaded hole, so that the bottom surface of the support rests on the bolt balls. The base plate is fixed to the top of the support, and the base plates on both purlin support units are at the same height. The vertical plate is fixed to the top surface of the base plate, and a purlin is provided between the vertical plates on the two purlin support units.

[0008] Furthermore, the threaded rod has a protective sleeve. When transporting the purlin unit, the protective sleeve is screwed into the threaded rod to protect it and prevent structural damage during transportation. When it is necessary to connect the threaded rod to the threaded hole of the bolt ball, the protective sleeve is unscrewed from the threaded rod.

[0009] Furthermore, the outer side of the protective case has anti-slip textures, making it easier to apply force to the protective case.

[0010] Furthermore, the bottom of the support has a groove, into which the threaded rod extends and is welded to the support, so that the connection between the threaded rod and the support is hidden in the support, preventing the threaded rod from detaching from the support.

[0011] Furthermore, a reinforcing plate is welded between the base plate and the upright plate to increase the connection strength between the base plate and the upright plate and improve the load-bearing capacity of the upright plate.

[0012] Furthermore, a reinforcing plate is welded between the base plate and the support to increase the connection strength between the base plate and the support, improve the strength of the support, and prevent deformation when the support rests on the bolt ball.

[0013] Furthermore, the second reinforcing plate is provided with a connecting part, and the connecting part is welded with the third reinforcing plate. The third reinforcing plate and the support are welded and fixed, which increases the connection strength between the second reinforcing plate and the support and ensures that the support has good strength.

[0014] Furthermore, the third reinforcing plate is a circular ring plate with a groove. The connecting part passes through the groove, and the support passes through the central hole of the third reinforcing plate, which facilitates the welding of the third reinforcing plate and the second reinforcing plate, while increasing the welding strength of the third reinforcing plate and the support, and further improving the strength of the support.

[0015] Furthermore, a fixing bolt is provided between the upright plate and the purlin, and a fixing nut is threaded onto the fixing bolt. The fixing nut is locked onto the purlin, which can firmly attach the purlin to the upright plate.

[0016] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0017] In this invention, the specifications of the purlin bracket unit are adjusted according to the size of the bolt ball when installing the purlin bracket unit.

[0018] When the bolt balls are of the same size, the purlin support units are of the same specification. At this time, the length of the supports is the same, and the vertical plates in the purlin support units are at the same height.

[0019] When the size of the bolt ball is different, the length of the support is adjusted according to the size of the bolt ball. During actual installation, the support is cut. When the threaded rod at the bottom of the support is threaded into the threaded hole, the bottom surface of the support is supported on the bolt ball. At this time, the length of the support is different, but the vertical plate in the purlin unit is at the same height.

[0020] When the vertical plates in the purlin support unit are at the same height, the purlins are installed horizontally to ensure the normal installation of the subsequent space frame. Attached Figure Description

Detailed Implementation

[0032] like Figures 1 to 9 As shown, this utility model provides a purlin support structure that is easy to assemble, including two bolt balls 1, each bolt ball 1 having a purlin support unit 3 mounted on it, and a connecting rod 2 welded between the two bolt balls 1.

[0033] The purlin support unit 3 includes a support 4, a base plate 5, and a vertical plate 6. The bolt ball 1 has a threaded hole 7, and the bottom of the support 4 has a groove 9. A threaded rod 8 extends into the groove 9 and is welded to the support 4, thus concealing the connection between the threaded rod 8 and the support 4 within the support 4 and preventing the threaded rod 8 from detaching from the support 4. The threaded rod 8 is threaded into the threaded hole 7 of the bolt ball 1, allowing the bottom surface of the support 4 to rest on the bolt ball 1.

[0034] The base plate 5 is welded to the top of the support 4, and the base plates 5 on the two purlin support units 3 are at the same height. A reinforcing plate 11 is welded between the base plate 5 and the support 4 to increase the connection strength between the base plate 5 and the support 4, improve the strength of the support 4, and prevent the support 4 from deforming when it is supported on the bolt ball 1.

[0035] The second reinforcing plate 11 is provided with a connecting part 12, and a third reinforcing plate 13 is welded to the connecting part 12. The third reinforcing plate 13 and the support 4 are welded and fixed, which increases the connection strength between the second reinforcing plate 11 and the support 4 and ensures that the support 4 has good strength. The third reinforcing plate 13 is a circular ring plate with a groove 14. The connecting part 12 passes through the groove 14, and the support 4 passes through the central hole 15 of the third reinforcing plate 13, which facilitates the welding of the third reinforcing plate 13 and the second reinforcing plate 11, and at the same time increases the welding strength between the third reinforcing plate 13 and the support 4, further improving the strength of the support 4.

[0036] The upright plate 6 is welded to the top surface of the base plate 5. At the same time, a reinforcing plate 10 is welded between the base plate 5 and the upright plate 6 to increase the connection strength between the base plate 5 and the upright plate 6 and improve the load-bearing capacity of the upright plate 6.

[0037] A purlin 20 is provided between the upright plates 6 on the two purlin support units 3. A fixing bolt 18 is provided between the upright plate 6 and the purlin 20. The fixing bolt 18 is threaded with a fixing nut 19. The fixing nut 19 is locked onto the purlin 20, which can firmly fix the purlin 20 onto the upright plate 6.

[0038] The threaded rod 8 is threadedly connected to a protective sleeve 16. The outer side of the protective sleeve 16 has anti-slip texture 17 to facilitate the application of force to the protective sleeve 16. When transporting the purlin unit 3, the protective sleeve 16 is screwed into the threaded rod 8 to protect the threaded rod 8 and prevent structural damage during transportation. When it is necessary to thread the threaded rod 8 into the threaded hole 7 of the bolt ball 1, the protective sleeve 16 is unscrewed from the threaded rod 8.

[0039] During construction, when the size of the bolt balls 1 is uniform, the purlin support units 3 have the same specifications, and the length of the supports 4 is the same, with the vertical plates 6 in the purlin support units 3 at the same height. When the size of the bolt balls 1 is different, supports 4 of different lengths are adjusted according to the size of the bolt balls 1. During actual installation, the supports 4 are cut. When the threaded rod 8 at the bottom of the supports 4 is threaded into the threaded hole 7, the bottom surface of the supports 4 is supported on the bolt balls 1. At this time, the lengths of the supports 4 are different, but the vertical plates 6 in the purlin support units 3 are at the same height.

[0040] When the vertical plates 6 in the purlin support unit 3 are at the same height, the purlins 20 are installed horizontally to ensure the normal installation of the subsequent space frame.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
