Steel grid is commonly used in buildings such as stadiums, exhibition centers, airports, and large factories, and is widely used for its excellent structural performance and aesthetic effects.

[0003] The steel grids in the prior art are generally connected by balls. One end of a plurality of steel frames is rotated and inserted into the inside of the balls so that the steel frames form a triangular structure through the balls. A plurality of triangular structures that have been spliced ​​together are assembled to form a steel frame, and the load of the steel frame is dispersed through the triangles. However, since the steel grids in the prior art are generally only spliced ​​and fixed to each other to form a steel frame, the steel frame composition structure of the prior art is relatively simple, and there is no other structure to share the load of the grid, resulting in the steel grid in the prior art being able to withstand a limited load and having a low strength.

[0012] The large-span steel grid with dispersed load has an inner wall of a fixing ring fixed to the reinforcing rod by bolts, and a triangle is formed between the supporting rod and the reinforcing rod. Therefore, when the grid is in use, the connecting rod will pull the reinforcing rod through the supporting rod, thereby dispersing the load of the grid during use, thereby compensating for the fact that the steel grids in the prior art are generally just spliced ​​and fixed to each other to form a steel frame, resulting in a relatively simple structure of the steel frame in the prior art, and there is no other structure to share the load of the grid, resulting in the defect that the steel grids in the prior art can withstand limited loads and low strength.

Embodiment 2

[0025] Based on the above Example 1, please refer to Figure 1 Figure 2 The connecting assembly includes a base 11, a cross bar 12 is installed on the top surface of the base 11, a baffle 15 is installed on the bottom surface of the cross bar 12, a reinforcing rod 13 is installed on the top surface of the splicing plate 1, a fixed shaft 14 is installed on the outer surface of the reinforcing rod 13, and the bottom surface of the cross bar 12 is fixedly connected to the top surface of the connecting rod 4.

[0026] There are eight reinforcing rods 13, which are evenly distributed on the top surface of the splicing plate 1 in a circular array. Two fixed shafts 14 are correspondingly distributed on the outer surface of each reinforcing rod 13, and one end of the reinforcing rod 13 is movably and rotatably connected to the inner wall of the rotating groove 2 through the fixed shaft 14.

[0027] Place the remaining reinforcing rods 13 into the remaining rotating grooves 2 in turn. When all the rotating grooves 2 are connected with reinforcing rods 13, the eight reinforcing rods 13 will be arranged in a circle. At this time, place the top plate 7 on the top surface of the splicing disk 1, and insert the fixing bolts 10 into the fixing holes 9 opened on the top surface of the top plate 7. By rotating the fixing bolts 10, the fixing bolts 10 fix the top plate 7 and the splicing disk 1 to each other. At this time, pass the connecting rod 4 from the bottom of the splicing disk 1 and out from the top surface of the top plate 7, and the bottom surface of the connecting rod 4 is installed with a support rod 5. At this time, adjust the upper and lower positions of the connecting rod 4 so that the fixing ring 6 installed on the surface of one side of the support rod 5 is consistent with the height of the reinforcing rod 13. When the heights are consistent, the fixing ring 6 wraps the four reinforcing rods 13 to fix the reinforcing rods 13.

[0028] The working principle and use process of the utility model are as follows: when it is necessary to assemble the steel grid, the splicing plate 1 is placed on the ground, and one end of the reinforcing rod 13 is placed on the inner wall of the rotating groove 2, so that the fixed shaft 14 installed on the outside of the reinforcing rod 13 is in the rotating groove 2. After the placement is completed, the remaining reinforcing rods 13 are placed in the remaining rotating grooves 2 in sequence. When all the rotating grooves 2 are connected with reinforcing rods 13, the eight reinforcing rods 13 will be arranged in a circle. At this time, the top plate 7 is placed on the top surface of the splicing plate 1, and the fixing bolts 10 are inserted into the fixing holes 9 opened on the top surface of the top plate 7. By rotating the fixing bolts 10, the fixing bolts 10 are used to fix the top plate 7 and the splicing plate 1 to each other. At this time, the connecting rod 4 is passed through the bottom of the splicing plate 1 The connecting rod 4 is inserted into and passes through the top surface of the top plate 7, and the supporting rod 5 is installed on the bottom surface of the connecting rod 4. At this time, the upper and lower positions of the connecting rod 4 are adjusted so that the fixing ring 6 installed on the surface of one side of the supporting rod 5 is consistent with the height of the reinforcing rod 13. When the heights are consistent, the fixing ring 6 wraps the four reinforcing rods 13 to fix the reinforcing rods 13. After the fixation is completed, the unfixed reinforcing rods 13 are rotated, and the four unfixed reinforcing rods 13 will rotate upward with the rotation groove 2 as the center point, so that the four reinforcing rods 13 form a cone. After the rotation is completed, the rotated reinforcing rods 13 are fixed by the remaining splicing plates 1, so that the reinforcing rods 13 form a triangle, so that the grid has a more solid support effect.

[0029] When the assembly is completed, the assembled grid is hoisted, and the top surface of the connecting rod 4 is made to movably contact with the bottom surface of the cross bar 12, and the two are fixedly connected by welding. When the welding is completed, the baffle 15 is laid on the bottom surface of the cross bar 12, and its bottom surface and the reinforcing rod 13 are welded to each other. When the grid is in use, because the connecting rod 4 and the cross bar 12 are fixedly welded, and four support rods 5 are installed on the outer surface of the connecting rod 4, each support rod 5 is installed on the outer surface of the support rod 5, and the inner wall of the fixing ring 6 is fixed to the reinforcing rod 13 by bolts, and a triangle is formed between the support rod 5 and the reinforcing rod 13. Therefore, when the grid is in use, the connecting rod 4 will pull the reinforcing rod 13 through the support rod 5, thereby dispersing the load of the grid during use.
