Description

Technical Field

[0001] The invention belongs to the technical field of grid flipping, and in particular relates to a ground lifting and flipping displacement control device for an auxiliary grid and a construction method thereof. Background Art

[0002] With the rapid development of modern construction technology, large-span, complex space grid structures have been widely used in public buildings and industrial facilities such as stadiums, exhibition halls, airport terminals, and large industrial plants due to their unique advantages, such as good spatial force performance, light structural deadweight, flexible modeling ability, and high economic benefits. As an important form of space grid structure, bolt ball grids are favored by the engineering community for their simple node connection, fast installation, and easy disassembly and reorganization.

[0003] In order to minimize the height of the assembly frame, steel grids with large drop are usually assembled horizontally, flipped asynchronously to the designed posture, and then lifted synchronously. During the flipping and lifting process, the grid is completely separated from the frame. When the grid is completely separated from the assembly frame, it is in a completely self-balanced state, which will produce a certain horizontal displacement.

[0004] In response to the above technical problems, the prior art discloses an invention patent entitled A steel grid flipping and lifting horizontal displacement device and control method (application publication number: CN116534724A), which includes methods for adjusting, releasing damping and controlling the horizontal displacement in a self-balancing state after the grid is separated from the assembly frame, thereby ensuring the safety of the entire flipping and lifting process.

[0005] However, when the grid frame adopts a large-span grid frame, its weight is large and the damper cannot withstand the force applied by the large-span grid frame. In addition, the guy rope is made of flexible material and is easily affected by the wind when the grid frame is flipped. Summary of the invention

[0006] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and to provide an auxiliary grid ground lifting and flipping displacement control device and a construction method thereof, which can flip the grid to a posture of 15°, and no horizontal displacement will occur during flipping.

[0057] When the grid 1 is not turned over, the steel wire rope 37 of the crane needs to be connected to the grid 1. In order to prevent the grid 1 from rotating, the grid 1 needs to be positioned. The specific design is: the base 25 is provided with a fixing member, the fixing member includes an L-shaped fixing plate 30, the fixing plate 30 is provided with a fixing groove 33, the base 25 is provided with a fixing column 26, the fixing column 26 is arranged in the fixing groove 33, the fixing column 26 is threadedly connected with a fixing nut 32, and the fixing nut 32 is locked on the fixing plate 30. The fixing plate 30 is provided with a protrusion 31, and the outer end of the corbel 7 is provided with a limiting groove 8. When the corbel 7 is placed in the notch 24, the protrusion 31 is embedded in the limiting groove 8 to prevent the corbel 7 from rotating, which is convenient for fixing the steel wire rope 37 on the grid end B. When the grid 1 needs to be turned over, the fixing member is removed. The present invention specifically designs the fixing member so that the fixing member limits the outer end of the corbel 7, which is convenient for quick installation and removal of the fixing member.

[0058] When the bracket 7 rotates to a set angle in the notch 24, the grid 1 maintains a 15° posture. At this time, the ball support 3 is in a vertical state.

The outer end of the support rod 19 is welded with an end plate 21, and the support rod 19 is welded with an adjustment nut 20. The adjustment nut 20 and the end plate 21 are welded and fixed, so as to facilitate the rotation of the support rod 19 and adjust the length of the support rod 19 extending out of the support tube 16, so that the support tube 16 after rotation is kept in a vertical state, and the end plate 21 can be fully supported on the base 25. The support member 9 can make both sides of the corbel 7 act on the base 25 to prevent the corbel 7 from rotating, so that after the grid 1 rotates to a set angle, the ball support 3 of the grid 1 always remains in a vertical setting, and the support member 9 can withstand the force applied by the grid 1 of a certain weight, so as to avoid the grid 1 in a set posture being affected by the wind and causing the angle of the grid 1 to change, and ensure the limited installation of the ball support 3 and the tire frame 39 in the later stage, and before the grid 1 is turned over, the support rod 19 can be kept in a horizontal state to avoid the influence of the support rod 19 on the turning of the grid 1.
