Description
Technical Field
[0001] The utility model belongs to the field of steel beam installation and steel beam stacking plates, and more specifically relates to a stacking plate structure used for steel beam hoisting. Background Art
[0002] During the construction of steel structure projects, lifting ears and mounting plates are usually set up for steel beam hoisting. After the steel beam installation (welding or high-strength bolt connection) is completed, the lifting ears and mounting plates need to be cut off and repainted with anti-corrosion paint.
[0003] In the prior art, the welding and installation of lifting lugs and mounting plates and their subsequent removal increase labor and materials, raise construction costs, and increase safety risks due to workers working at heights. At the same time, the lifting lugs on the steel beams cannot limit the angle between the steel beams and the steel wire ropes (when lifting the steel beams, the angle between the steel wire ropes and the steel beams is 45°-60°). Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a yard plate structure for steel beam hoisting, which has the advantages of reducing the workload of ear plate welding, ear plate high-altitude cutting and paint repainting, and limiting the angle between the shackle and the wire rope and the steel beam body.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A yard plate structure for steel beam hoisting, comprising a steel beam body, at least one lifting lug and a yard plate are arranged on the steel beam body along the length direction, a hoisting hole is arranged on the lifting lug, the lifting lug and the yard plate are integrally formed, and one end of the yard plate extends out of the end of the steel beam body;
[0007] Grooves are symmetrically provided on both side walls of the lifting ear, and circular holes are provided in the grooves. The circular holes penetrate the side walls of the lifting ear, and angle limiting components for limiting the angle of the shackle are installed in the two grooves. The angle limiting components are detachably installed on the lifting ear through bolts and nuts.
[0008] The advantages of this solution are at least that: the lifting lug and the yard plate are formed in one piece and a lifting hole is opened on it. After the steel beam body is hoisted into place, the worker can remove the hook on the bull leg, avoiding the need to walk along the steel beam body to the middle of the steel beam body to remove the shackle. At the same time, it also reduces the workload of welding, high-altitude cutting and repainting of the lug plate. By setting an angle limit component, the angle between the shackle and the wire rope and the steel beam body is controlled at 45°-60°, ensuring the stability and safety of the hoisted object during the hoisting process. The angle limit component is installed on the lifting lug in a detachable manner so that the angle limit component can be reused.
[0009] The utility model is further configured as follows: at least two grooves are provided on the side wall of the lifting ear, the two grooves are respectively a first groove and a second groove, one side wall of the first groove forms an angle of 45° with the top surface of the lifting ear, and the other side wall forms an angle of 60° with the top surface of the lifting ear;

[0011] The advantages of this solution are at least that: two grooves are set, and angle limit assemblies are installed in the first groove and the second groove, wherein the angle limit assembly in the second groove is to prevent the angle between the shackle and the steel wire rope and the steel beam body from being too small (less than 45°), thereby increasing the tension of the steel wire rope and causing the steel wire rope to break more easily, and the angle limit assembly in the first groove is to prevent the angle between the shackle and the steel wire rope and the steel beam body from being too large, which will reduce the tension of the steel wire rope and make the object unable to be lifted. In addition, too large an angle will increase the friction of the steel wire rope, causing the steel wire rope to wear more, thereby reducing its service life.
[0012] The utility model is further configured as follows: the angle limiting assembly comprises a first limiting plate and a second limiting plate, the first limiting plate and the second limiting plate are provided with countersunk holes, and the size and shape of the through holes of the countersunk holes are the same as those of the circular holes.
[0013] The advantage of this solution is at least that the angle limit assembly is divided into a first limit plate and a second limit plate, and the two-part arrangement makes the angle limit assembly more convenient to install.
[0014] The utility model is further configured as follows: two first vertical plates are installed on the upper surface of the first lower limit plate, sliding rods are installed on the two first vertical plates, two second vertical plates are installed on the upper surface of the second limit plate, sliding holes are provided on the two second vertical plates, the sliding rods are slidably installed in the sliding holes, and a limiting block is installed at the end of the sliding rod.
[0015] The advantage of this solution is at least that: by providing the first vertical plate, the sliding rod, the second vertical plate, the sliding hole and the limit block, the first limit plate and the second limit plate are connected together, making installation more convenient and quick, and avoiding the need to find a component separately.
[0016] The utility model is further configured as follows: mounting holes are opened on the side walls of the first limiting plate and the second limiting plate, the mounting holes penetrate the first limiting plate and the second limiting plate, threaded rods are slidably installed in the mounting holes, and nuts 2 are threadedly connected to the threaded rods.
[0017] The advantages of this solution are at least that: the arrangement of the threaded rod, the mounting hole and the nut 2 enables the first limit plate and the second limit plate to be more firmly fixed on the lifting ear through the locking between the bolt, the nut 1 and the threaded rod, the nut 2 when they are installed on the side wall of the lifting ear.
[0018] The utility model is further configured as follows: a convex block is installed on the side wall of the first limiting plate, a blind hole is opened on the side wall of the second limiting plate, and the convex block and the blind hole are matched.
[0019] The advantage of this solution is at least that the provision of the protrusions and the blind holes further strengthens the connection strength between the first limiting plate and the second limiting plate.
[0020] The utility model is further configured as follows: at least two lifting ears and yard plates are provided, and adjacent lifting ears and yard plates are symmetrically installed on the upper surface of the steel beam body.
[0021] The advantage of this solution is at least that at least two lifting ears and yard plates are provided, which facilitates the docking and installation work on the steel beam body with a wider width.
[0022] The utility model is further configured as follows: paint is coated on the outer surfaces of the first limiting plate, the second limiting plate, the first vertical plate, the second vertical plate and the limiting block.

[0025] 1. By setting the lifting lugs and yard plates and forming them in one piece, after the steel beam body is hoisted into place, workers can remove the hooks on the bull legs, avoiding the need to walk along the steel beam body to the middle of the steel beam body to remove the shackles. At the same time, it also reduces the workload of welding, high-altitude cutting and paint re-painting of the lugs. By setting the angle limit assembly, the angle between the shackle and the wire rope and the steel beam body is controlled at 45°-60°, ensuring the stability and safety of the hoisted objects during the hoisting process. The angle limit assembly is installed on the lifting lug in a detachable manner, so that the angle limit assembly can be reused.

By setting the first vertical plate, the sliding rod, the second vertical plate, the sliding hole and the limit block, the first limit plate and the second limit plate are connected together, which makes the installation more convenient and quick, and avoids the need to find a component separately.

The lifting lug 2 and the yard plate 3 are integrally formed, and one end of the yard plate 3 extends out of the end of the steel beam body 1. The steel beam body 1 is an H-shaped, box-shaped or other form of steel beam.
[0035] Furthermore, in order to facilitate the docking work of the steel beam body 1 with a wider width, at least two lifting ears 2 and yard plates 3 are provided, and adjacent lifting ears 2 and yard plates 3 are symmetrically installed on the upper surface of the steel beam body 1.
[0036] like Figure 3 As shown, grooves 5 are symmetrically provided on both side walls of the lifting ear 2, and circular holes 8 are provided in the grooves 5. The circular holes 8 penetrate the side walls of the lifting ear 2, and an angle limiting assembly 6 for limiting the angle of the shackle is installed in the grooves 5. The angle limiting assembly 6 is detachably installed on the lifting ear 2 by bolts 7 and nuts 9.
[0037] In the requirements of 17G911 of "Safety Protection of Steel Structure Construction", when steel components are hoisted, the angle between the steel wire rope and the steel beam must be greater than 45°. In order to prevent the problem that the angle between the shackle and the steel wire rope and the steel beam body 1 is too small or too large, in some embodiments, at least two grooves 5 are provided on the side wall of the lifting ear 2, and the two grooves 5 are respectively a first groove 501 and a second groove 502. One side wall of the first groove 501 forms an angle of 45° with the top surface of the lifting ear 2, and the other side wall forms an angle of 60° with the top surface of the lifting ear 2.
[0038] The two side walls of the second groove 502 form an angle of 45° with the top surface of the lifting ear, the first groove 501 and the second groove 502 are distributed on both sides of the lifting hole 4, and the first groove 501 and the second groove 502 are both installed with an angle limiting component 6, wherein the function of the angle limiting component 6 in the first groove 501 is to limit the wire rope and the shackle to avoid the problem of too large an angle between the wire rope and the shackle and the steel beam body 1, and the function of the angle limiting component 6 in the second groove 502 is to limit the wire rope and the shackle to avoid the problem of too small an angle between the wire rope and the shackle and the steel beam body 1.
[0039] Furthermore, the angle limiting assembly 6 includes a first limiting plate 601 and a second limiting plate 602 . The first limiting plate 601 and the second limiting plate 602 are provided with countersunk holes 10 . The size and shape of the through hole of the countersunk hole 10 are the same as those of the circular hole 8 .

Two second vertical plates 13 are installed on the upper surface of the second limit plate 602, and sliding holes 14 are provided on the two second vertical plates 13. The sliding rods 12 are slidably installed in the sliding holes 14.
[0041] Furthermore, in order to prevent the sliding rod 12 from sliding out of the sliding hole 14 , a limiting block 15 is installed at the end of the sliding rod 12 .
[0042] It is worth mentioning that the outer surfaces of the first limiting plate 601, the second limiting plate 602, the first vertical plate 11, the second vertical plate 13 and the limiting block 15 are painted, which is not shown in the paint diagram.

Furthermore, a protrusion 17 is installed on the side wall of the first limit plate 601, and a blind hole 18 is provided on the side wall of the second limit plate 602, and the protrusion 17 and the blind hole 18 are adapted to each other.
[0044] The working process and beneficial effects of the utility model are as follows:
[0045] Before lifting the steel beam body 1, the integrally formed lifting ear 2 and code plate 3 are welded to the upper surface of the steel beam body 1, and then the first limit plate 601 and the second limit plate 602 are fixed to the side wall of the lifting ear 2 by bolts 7, nuts 1 9 and threaded rods 6021 and nuts 2 16, and then the shackle is installed on the lifting hole 4, and the wire rope is connected to the shackle. After the preparation is completed, the lifting work is ready, wherein the first limit plate 601 and the second limit plate 602 limit the angle between the shackle and the wire rope and the steel beam body 1, so as to avoid the angle between the shackle and the wire rope and the steel beam body 1 being too small or too large, thereby improving the safety of lifting.
[0046] After the steel beam body 1 is hoisted into place, workers can remove the buckles on the bull legs, avoiding the need to walk along the steel beam body 1 to the middle of the steel beam body 1 to remove the buckles. It also reduces the workload of welding and high-altitude cutting of the ear plates and repainting of paint required by workers.
