[0001] The utility model relates to the field of space steel network buildings, and more specifically, to a large-span assembled space steel network building structure. Background Art

[0002] Spatial steel structure buildings refer to steel structure buildings with larger spans, which are usually used in large buildings such as airports, railway stations, and gymnasiums.

[0003] When constructing existing space steel structure buildings, the steel materials need to be fixed together by welding, and then spliced ​​one by one to form a large network frame. However, due to the large size of the building, a large number of steel materials need to be welded, which increases the workload of the staff, and the welded steel materials are difficult to disassemble, which is not conducive to later maintenance and secondary use of steel materials.

[0004] Therefore, in order to solve the above problems, a large-span prefabricated spatial steel network building structure is proposed. Utility Model Content

[0027] Example:

[0028] See also Figure 1 - Figure 4A large-span assembled space steel network building structure comprises a lower support beam 1, an upper support beam 2 and a Y-shaped steel 3. The bottom surface of the upper support beam 2 is fixedly connected to two installation frames 4. The tops of both sides of the Y-shaped steel 3 are fixedly connected to the inside of the two installation frames 4 by bolts. A through groove 11 is penetrated through the top surface of the lower support beam 1. The bottom of the Y-shaped steel 3 is penetrated and arranged inside the through groove 11. A support assembly 5 is arranged on the top surface of the lower support beam 1. The support assembly 5 comprises two first fixed seats 51 fixedly connected to the top surface of the lower support beam 1 and two clamping frames 52 symmetrically arranged on both sides of the Y-shaped steel 3. The sizes of the two clamping frames 52 are adapted to the sizes of the vertical sections of the Y-shaped steel 3. The top surfaces of the two first fixed seats 51 are rotatably connected to rotating rods 53. One end of the two rotating rods 53 is rotatably connected to one side of the two clamping frames 52 respectively.

[0029] Specifically, one side of one of the clamping frames 52 is provided with two positioning grooves 54 , and one side of the other clamping frame 52 is fixedly connected with two positioning blocks 55 , and the two positioning blocks 55 are respectively engaged with the two positioning grooves 54 .

[0030] In this solution, the mounting frame 4 is used to fix the two inclined sections at the top of the Y-shaped steel 3. The two inclined sections at the top of the Y-shaped steel 3 are provided with threaded holes, and the mounting frame 4 and the top of the Y-shaped steel 3 are fixed by bolts. Compared with the traditional "X" cross-shaped steel, the two inclined sections of the Y-shaped steel 3 can disperse the pressure on the upper support beam 2, which is the prior art. The support assembly 5 is used to support the Y-shaped steel 3 at an angle. During installation, the staff first inserts the Y-shaped steel 3 into the through groove 11, and then places the two first fixing seats 51 on both sides of the Y-shaped steel 3. By adjusting the angle of the rotating rod 53 and cooperating with the guiding effect between the positioning groove 54 and the positioning block 55, the two clamping frames 52 are pressed on both sides of the Y-shaped steel 3, and then the positions of the two first fixing seats 51 are fixed by bolts. The support assembly 5 is not only simple to install and does not require welding, but also can support both sides of the Y-shaped steel 3, so that the oblique external force on the Y-shaped steel 3 is dispersed to the lower support beam 1, thereby protecting the Y-shaped steel 3.

[0031] See also Figure 1 , Figure 2 and Figure 4 Both sides of the Y-shaped steel 3 away from the supporting assembly 5 are fixedly connected with fixing plates 6, and two first threaded holes 61 are penetrated through one side of the fixing plate 6.

[0032] Specifically, two second fixing seats 7 are fixedly connected to the top surface of the lower support beam 1 , and two second threaded holes 71 are penetrated through one side of the two second fixing seats 7 close to the Y-shaped steel 3 .

[0033] Specifically, the inner thread of the second threaded hole 71 is threadedly connected with a fixing bolt 8 .

[0034] Specifically, the positions of the two first threaded holes 61 match the positions of the two second threaded holes 71 , and the second fixing seat 7 is fixedly connected to the Y-shaped steel 3 via fixing bolts 8 disposed thereon.

[0035] In this solution, the second fixing seat 7 is used to fix the lower support beam 1 through bolts, and threaded holes are also opened on both sides of the Y-shaped steel 3 corresponding to the first threaded holes 61. The Y-shaped steel 3 and the second fixing seat 7 can be fixed by fixing bolts 8, so that the Y-shaped steel 3 is fixed to the lower support beam 1, and the operation is simple.

[0036] Working principle: During installation, the staff first inserts the Y-shaped steel 3 into the through groove 11, then places the upper support beam 2 on the top of the Y-shaped steel 3, and fixes the inclined section on the top of the Y-shaped steel 3 to the installation frame 4 with bolts. Then the staff aligns the second threaded hole 71 and the first threaded hole 61 on the second fixing seat 7 and the fixing plate 6, and fixes the two with the fixing bolts 8, thereby fixing the Y-shaped steel 3 on the lower support beam 1. Finally, the staff aligns and clamps the two clamping frames 52 on both sides of the Y-shaped steel 3, and adjusts the rotating rod 53 to make the first fixing seat 51 fit on the lower support beam 1, and then fixes the first fixing seat 51 with bolts to complete the splicing of the grid.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
