Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel structure construction, in particular to the hoisting technology of steel structures, and specifically to a steel structure hoisting device in a confined space. Background Technique
[0002] With the rapid development of China's construction industry, as a common structural form, steel structures are widely used in various stadiums, high-rise buildings, landmark buildings and other structures due to their advantages of large space, strong flexibility and fast construction.
[0003] However, due to the fast construction progress of steel structures, the main structure can be quickly formed, resulting in some small components inside the building often not being hoisted in time due to schedule adjustments. When most of the steel structure hoisting is completed, there may sometimes be situations where tower cranes and truck cranes cannot be used for construction. Usually, when this phenomenon occurs, due to the lack of hoisting capacity, manual handling is often used, which is not only time-consuming and laborious, but also fails to meet the requirements of safe and civilized construction. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the above defects and provide a hoisting device for installing steel structures in a limited space to meet the vertical transportation and hoisting requirements of some small components inside the structure.
[0005] To achieve the above purpose, the utility model is realized as follows:
[0006] A steel structure hoisting device in a confined space, characterized in that it includes a support (1), an embedded part (5) and a chain hoist (4); the embedded part (5) is arranged in the structural wall and connected to the support (1), and the chain hoist (4) is arranged on the support (1), and the chain hoist (4) is used for hoisting steel structures; it also includes a reinforcing rib plate (2), and the reinforcing rib plate (2) is respectively connected to the support (1) and the embedded part (5); it also includes an extension plate (3), the extension plate (3) is arranged on the support (1) and extends outward, and a hole is opened at the end of the extension plate (3), and the hole is used for connecting the chain hoist (4).
[0007] For the above-mentioned steel structure hoisting device in a confined space, the support (1) is triangular: including a steel bottom plate and channel steels arranged vertically and obliquely on the steel bottom plate.
[0008] For the above-mentioned steel structure hoisting device in a confined space, it also includes a reinforcing rib plate (2), and the reinforcing rib plate (2) is respectively connected to the support (1) and the embedded part (5).
[0009] The steel structure hoisting devices within the above-mentioned confined space are used in pairs; the triangular supports are placed on the top surface of the structure, the reinforcement plates are welded to the structure embedded part panels, and the hoist chain hooks are connected to the openings of the extension plates. Install on the other side according to the above operations.
[0010] During use, slowly place the hoist chain on the ground. The ground slinger connects the buckle to the steel beam lifting lug. The operators on both sides then pull the hoist chain to vertically transport the steel beam to the designated position. After the steel beam is installed, unhook it, cut off the rear reinforcement plate, and remove the device.
[0011] The above-mentioned hoisting device proposed by the present utility model can also perform hoisting operations within a confined space, meeting the hoisting use requirements. Moreover, the entire device has a simple structure, and all the required materials are common materials, making it relatively convenient to manufacture. Description of the Drawings
