Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically, to a long-span suspension structure and its construction method. Background Technology

[0002] A suspension cable is a cable that bears a load between two suspension points. Each point in a suspension cable can only withstand tensile force, and the tension at each point is along the tangent to the cable at that point. The main cables of a suspension bridge and power transmission lines are examples of suspension cables.

[0003] Chinese patent application publication number CN108179814A discloses an adjustable support device and method for cable-stayed steel suspension in an ultra-large span steel structure. It includes two fixed supports on both sides, each fixed support is provided with at least two cable-stayed steel suspension rods, each cable-stayed steel suspension rod is provided with an adjustment device, and a support tray is provided between the cable-stayed steel suspension rods on both sides. One end of each cable-stayed steel suspension rod is connected to the fixed support by a bolt, and the other end is connected to the support tray by a bolt. This invention addresses the issue of adjustable steel suspension cable support devices installed on steel structure columns. Cable trays and pipelines are placed on pallets, and the stability of the pallets is adjusted using steel suspension cables. This avoids problems such as lack of ground support for supports in large-span workshops, leading to reduced construction efficiency and increased construction costs. However, the present invention addresses the challenge of adjusting the position of the inclined steel suspension cable tie rod when faced with pallets of different specifications. This reduces the applicability of the inclined steel suspension cable tie rod to different pallet sizes. Summary of the Invention

[0004] Firstly, the purpose of this invention is to provide an ultra-high disc-lock support frame that can be applied to support trays of different sizes, thereby improving applicability.

[0005] The embodiments of the present invention are achieved through the following technical solutions:

[0006] A long-span suspension structure includes parallel and spaced columns. A fixed beam is provided perpendicular to one side of each column.

[0007] Furthermore, a first adjustment groove is provided on the fixed beam along the length direction of the fixed beam. The end of the first adjustment groove away from the column is provided through the fixed beam. The first adjustment mechanism includes a first adjustment block provided at one end of the cable body. Multiple first adjustment blocks are snapped and slidably connected in the first adjustment groove. A first fixing mechanism is provided in the first adjustment groove for fixing the first adjustment block to any moved position.

[0008] Furthermore, the first fixing mechanism includes a screw rod rotatably disposed in the first adjusting groove along the length direction of the first adjusting groove, a first adjusting block away from the column is sleeved and threadedly connected to the screw rod among a plurality of first adjusting blocks, a rotating handle for driving the screw rod to rotate is provided on the column, and an adjusting member for adjusting the distance between adjacent first adjusting blocks is provided between adjacent first adjusting blocks when the first adjusting block away from the column is moved.

[0009] Furthermore, the adjusting member includes an adjusting rod disposed between adjacent first adjusting blocks. The adjusting rod is configured as a telescopic structure, which includes a fixed rod and a movable rod inserted into and slidably connected within the fixed rod. The fixed rod is fixedly disposed on one of the adjacent first adjusting blocks, and the movable rod is fixedly disposed on the other adjacent first adjusting block. The fixed rod is provided with a fixing member for fixing the movable rod to any position within the fixed rod.

[0010] Furthermore, the first adjusting block is provided with a first connecting hole, and one end of the cable is fixedly provided with a first hook for passing through the first connecting hole. The end of the first hook away from the cable is sleeved and threadedly connected with a first nut for preventing the first hook from disengaging from the first connecting hole. The cable is detachably connected to the first adjusting block through the first hook and the first connecting hole.

[0011] Furthermore, the support tray is provided with a second adjustment groove, which is arranged along the length direction parallel to the first adjustment groove. Both ends of the second adjustment groove pass through the support tray. The other end of the cable is provided with a second adjustment block that is snapped into and slidably connected in the second adjustment groove. The second adjustment block is provided with a connector for fixing the second adjustment block to any position in the second adjustment groove.

[0012] Furthermore, the connector includes a connecting bolt that passes through and is threaded onto the second adjusting block.

[0013] Furthermore, the second adjusting block is provided with a second connecting hole, and the other end of the cable is fixedly provided with a second hook for passing through the second connecting hole. The end of the second hook away from the cable is sleeved and threadedly connected with a second nut for preventing the second hook from disengaging from the second connecting hole. The cable is detachably connected to the second adjusting block through the second hook and the second connecting hole.

[0014] Secondly, the purpose of this invention is to provide a construction method for an ultra-high disc-type support frame, which can be applied to support trays of different sizes, thereby improving applicability.

[0017] Select a specified number of cables according to the size of the support tray. Adjust the length of the adjusting rod by moving the movable rod within the fixed rod. Fit the first adjusting block, which is furthest from the column, onto the screw rod and thread it in. Slide the remaining first adjusting blocks into the first adjusting groove. Rotate the handle to rotate the screw rod. Because the first adjusting blocks are slidably set in the first adjusting groove, the first adjusting block furthest from the column moves on the screw rod, causing the remaining first adjusting blocks to move. This adjusts the position of the cables on the fixed beam. Move the second adjusting block into the second adjusting groove and fix it with connecting bolts to adjust the position of the cables on the support tray. By adjusting the number and position of the cables, different numbers and positions of cables can be used for support trays of different sizes.

[0019] 1. Select a specified number of cables according to the size of the support tray. Adjust the length of the adjusting rod by moving the movable rod within the fixed rod. Fit the first adjusting block furthest from the column into the screw rod and thread it onto the screw. Slide the remaining first adjusting blocks into the first adjusting groove. Then, rotate the handle to rotate the screw rod. Because the first adjusting blocks are slidably set in the first adjusting groove, the first adjusting block furthest from the column moves on the screw rod, causing the remaining first adjusting blocks to move. This adjusts the position of the cables on the fixed beam. Move the second adjusting block into the second adjusting groove and fix it with connecting bolts to adjust the position of the cables on the support tray. By adjusting the number and position of the cables, different numbers and positions of cables can be used for support trays of different sizes. Attached Figure Description
