Description

Technical Field

[0001] The utility model relates to the field of scaffolding, in particular to a basket-type scaffolding I-beam dismantling operation platform. Background Art

[0002] During construction, cantilever scaffolding is a common tool that enables construction workers to work safely at height. There are some challenges and risks in the assembly, dismantling and maintenance of cantilever scaffolding, especially during the dismantling stage, when special attention needs to be paid to the safety of construction workers.

[0003] When using a basket-style cantilever scaffold for construction, when the I-beam is removed after the external frame is removed, how to ensure the safety of the workers and the convenience of removal becomes the top priority. The traditional method is to lay a wooden springboard on the steel beam and use ropes to fix the wooden springboard to the steel beam, and the workers remove them one by one. However, this method has poor safety due to the low strength and rigidity of the wooden springboard, and the wooden springboard needs to be fixed or removed every time, which is inconvenient for construction; another method is to weld a hook at the bottom of the steel scaffolding board to hook the I-beam and then remove it in turn. After each steel beam is removed, the scaffolding board needs to be manually lifted and moved backwards. This method ensures the stability and strength of the scaffolding board to a certain extent, but the overall self-weight of the scaffolding board is large, and the workers need to lift the scaffolding board before moving it to the rear steel beam every time they move at high altitude, which is inconvenient to operate.

[0020] The utility model provides a basket-type scaffolding I-beam dismantling work platform, comprising a frame 1, a support plate 2 installed on the frame 1, two first hooks 3 and two second hooks 4; the frame 1 is made of I-beam, and the assembly of the frame 1 is a conventional technical means, which will not be repeated here. The support plate 2 is composed of a patterned steel plate welded on a frame composed of square steel welded.

[0021] Each first hook 3 includes a connecting portion 31 and a supporting portion 32 connected to both ends of the connecting portion 31; the two supporting portions 32 are symmetrically arranged along the midpoint of the connecting portion 31; the supporting portion 32 is used to be movably connected to the bottom of the frame 1; when the supporting portion 32 at one end is movably connected to the bottom of the frame 1, the other end passes through the supporting plate 2. The spacing between the two first hooks 3 is adapted to the distance between two adjacent frames 1. One end of each second hook 4 is connected to the bottom of the supporting plate 2, and the other end passes through the supporting plate 2. The first hook 3 passes through one side of the supporting plate 2 and is fixedly connected to the top of the second hook 4.

[0022] A hook lug plate 33 is provided at each side of the first hook 3 near the support portion 2; the hook lug plates 33 are symmetrically arranged along the center of the midpoint of the connection portion 31; a scaffolding lug plate 41 is provided on one side of the top of the second hook 4; the hook lug plate 33 and the scaffolding lug plate 41 are located at the top of the support plate 2. A rotation hole 34 is provided at the center of the connection portion 31 of the first hook 3, and a rotation fixing screw 35 is inserted in the rotation hole 34. The rotation fixing screw 35 is fixedly connected to the bottom of the support plate 2, and the first hook 3 can rotate through the rotation fixing screw 35. Two limiting grooves 21 are provided on the support plate 2, and each first hook 3 and the second hook 4 connected thereto pass through the corresponding limiting groove (21); the width of the limiting groove 21 is less than the length of the rotation fixing screw 35, and greater than the sum of the diameter of the first hook 3 and the diameter of the second hook 4; the length of the limiting groove 21 is greater than the length of the connection portion 31 of the first hook 3. The first hook 3 and the second hook 4 are made of grade 3 steel with a diameter of not less than 18 mm. The hook lug plate 33 and the scaffolding lug plate 41 are stamped lug plates. The first hook 3 and the second hook 4 can be integrally stamped, or the hook ear plate 33 and the scaffolding ear plate 41 can be punched and then welded to the first hook 3 and the second hook 4. The hook ear plate 33 and the scaffolding ear plate 41 are positioned in the same way to ensure that the high-strength bolts 5 are effectively inserted and fixed. Each first hook 3 and the connected second hook 4 pass through the corresponding limiting groove 21; each rotating fixing screw 35 is fixed below the limiting groove 21 and fixed by the bolts at the bottom of the support plate 2. The spiral fixing screw 35 passes through the bolts and is perpendicular to the limiting groove 21. The connecting parts of the two first hooks 3 are arranged opposite to each other.

[0023] The working process of the utility model is as follows: when dismantling the I-beam, place the support plate 2 on the frame 1; hook the support parts 32 of the two opposite first hooks 3 onto the I-beam, the left support part 32 hooks the left side of the corresponding I-beam, and the right support part 32 hooks the right side of the corresponding I-beam; align the hook ear plate 33 of each first hook 31 with the scaffolding ear plate 41 of the corresponding second hook, and then fix the high-strength bolt 5. The worker can remove the adjacent I-beam on the support plate 2. After the dismantling operation is completed here, the staff does not need to lift the support to move; after the high-strength bolt 5 is contacted and fixed, rotate the two first hooks 3 to make the support part 32 detach from the frame; the first hook 3 on the left rotates clockwise, and the first hook 3 on the right rotates counterclockwise; push the support plate 2 to the next position beyond the working position, repeat the installation steps, and the construction personnel can remove the I-beam under the support plate of the previous working position. The reliability of the support plate 2 fixed to the frame 1 in each operation can be guaranteed, which greatly improves the convenience and safety of the workers' operation.
