Technical Field

[0001] The utility model relates to the technical field of bolt sphere joints of steel structure grids, and specifically relates to a leveling structure for bolt sphere joints of steel structure grids. Background Technique

[0002] The connection structure principle of the bolt sphere joint is as follows: First, weld the cone head or sealing plate with bolts at both ends of the steel pipe rod. A long hexagonal sleeve (or long hexagonal plain nut) is sleeved on the screw rod protruding from the cone head or sealing plate, and the bolt and the sleeve are connected together with a pin or fastening screw. During assembly, directly turn the long hexagonal sleeve, and drive the bolt to rotate through the pin or fastening screw, so that the bolt is screwed into the sphere until the bolt head is tightly attached to the sealing plate or cone head. After all the intersecting rods are connected in this way, the joint is formed, and the tightening degree of the bolt is controlled by the pin.

[0003] The current node treatment measure is to fix the bolt spheres of the steel grid to the visually same height and directly carry out the lapping and welding work. However, often when the grid structure is too long, the overall effect is crooked and distorted, and there are large displacement deviations between the bolt sphere joints of the steel grid, affecting the overall effect.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a leveling structure for bolt sphere joints of steel structure grids is proposed. Content of the Utility Model

The adjustment component for adjusting the level of the bolt sphere main body is installed at the end of the connecting rod. The adjustment component includes a base, a connecting piece, a first screw rod, a threaded sleeve, a second screw rod and a connecting seat.

[0020] As Figures 1 - 2 shown, a leveling structure for a bolt ball joint of a steel structure grid includes a bolt ball main body 1 and an adjustment assembly 4. An installation groove 2 is formed on the outer wall of the bolt ball main body 1, and a connecting rod 3 is threadedly connected inside the installation groove 2. The adjustment assembly 4 for adjusting the level of the bolt ball main body 1 is installed at the end of the connecting rod 3. The adjustment assembly 4 includes a base 401, a connecting piece 402, a first screw rod 403, a threaded sleeve 404, a second screw rod 405, and a connecting seat 406. A connecting piece 402 is provided on the outer wall of the base 401, and one end of the connecting piece 402 is rotatably connected to a first screw rod 403. The end of the first screw rod 403 is threadedly connected to a threaded sleeve 404, and the end of the threaded sleeve 404 is threadedly connected to a second screw rod 405. The end of the second screw rod 405 is rotatably connected to a connecting seat 406.

[0021] By adopting the above technical solution, when the bolt ball main body 1 needs to adjust the angle, the threaded sleeve 404 is controlled to rotate, and the threaded sleeve 404 is made to pull the corresponding first screw rod 403 and second screw rod 405 to move relatively. Then, the vertical laser emitter 6 is used to irradiate the smooth surface of the top of the support seat 10, and the angle of reflection of the laser beam is observed to adjust the threaded sleeve 404.

[0022] As Figure 3 shown, a docking groove 5 is formed on the top of the base 401, and a vertical laser emitter 6 is provided below the base 401.

[0023] By adopting the above technical solution, the vertical laser emitter 6 is used to make the inclination angle more intuitive when the bolt ball main body 1 is installed.

[0024] Furthermore, a ball head seat 7 is provided below the middle of the base 401, and a sphere 8 is rotatably connected to the bottom of the ball head seat 7.

[0025] By adopting the above technical solution, the sphere 8 is used to support the base 401 while reducing interference.

[0026] Furthermore, a support rod 9 is fixedly connected to the bottom of the sphere 8, and the support rod 9 is rotatably connected to the base 401 through the sphere 8 and the ball head seat 7.

[0027] Furthermore, a support seat 10 is fixedly installed at the end of the support rod 9, and a bottom plate 11 is fixedly installed at the bottom of the support seat 10.

[0028] By adopting the above technical solution, the bottom plate 11 is used to install and limit the whole adjusting component 4.

[0029] Furthermore, the second screw rod 405 is rotatably connected to the bottom plate 11 through a connecting seat 406, and four groups of connecting seats 406 are provided.

[0030] Working principle: When using the leveling structure of the bolt ball joint of the steel structure grid, first place a connecting rod 3 of appropriate length into the docking groove 5 opened at the top of the base 401, and dock the top of the connecting rod 3 with the bolt ball main body 1. When the angle of the bolt ball main body 1 needs to be adjusted, control the rotation of the threaded sleeve 404, and make the threaded sleeve 404 pull the corresponding first screw rod 403 and second screw rod 405 to move relatively. Then, the vertical laser emitter 6 irradiates the smooth surface of the top of the support seat 10, and observe the reflection angle of the laser beam to adjust the threaded sleeve 404. This is the working principle of the leveling structure of the bolt ball joint of the steel structure grid.
