Description

Technical Field

[0001] This utility model relates to auxiliary tools used for the installation of steel profiles, and in particular to an auxiliary device for high-altitude installation of steel profile connecting plates. Background Technology

[0002] In existing technologies, structural steel, with its standardized dimensions and shapes, high rigidity, and low cost, has been widely used in the supporting structures of large bridges, buildings, and space frames. Especially with the proliferation of steel structure buildings, the installation of structural steel has become a crucial factor determining the construction schedule. Simultaneously, the safety issues of high-altitude installation of structural steel have become increasingly prominent. For example, in current designs, the connection between I-beams uses double connecting plates to connect them into a single unit. To facilitate the installation of I-beams in the air, the double connecting plates at both ends of the structural steel are often temporarily fixed to the steel on the ground with bolts before being hoisted to the work surface for installation. After hoisting into place, one end of the steel section can be directly bolted to the existing steel structure via double connecting plates. However, because the double connecting plates protrude from the end of the steel section, the steel section cannot be directly aligned and connected. It is necessary to adjust the position of one or two connecting plates at this end to avoid the connecting plates blocking the alignment of the steel section and thus affecting the installation. In the process of adjusting the position of the connecting plates at this end, it is necessary to unscrew the temporary fixing bolts of the connecting plates and adjust the position of the connecting plates. This process is prone to accidents of connecting plates falling from height, and the installation efficiency is low. Utility Model Content

[0003] To facilitate rapid high-altitude connection and installation of steel profiles, improve installation efficiency and reduce installation costs, and prevent accidents caused by falling objects from high-altitude connecting parts, this utility model discloses an auxiliary device for high-altitude installation of steel profile connecting plates.

[0004] The technical solution adopted by this utility model to achieve the purpose of the invention is: a high-altitude installation auxiliary device for steel connecting plates.

[0005] The auxiliary device includes: a left spindle, a right spindle, an elastic limiting sleeve, and a limiting sleeve control spring.

[0006] The elastic limiting sleeves are respectively fitted onto the left and right spindles via the limiting sleeve control springs, forming an elastic connection structure in which the elastic limiting sleeves slide on the left and right spindles under the control of the limiting sleeve control springs.

[0007] The left and right spindles form a threaded connection structure.

[0008] The advantages of this invention are: simple structure, convenient use, and the ability to pre-connect the connecting plate and the steel profile without affecting the hoisting of the steel profile. It greatly improves installation efficiency, prevents accidents caused by falling objects from heights, and is reusable.

[0009] The present invention will now be described in detail with reference to the accompanying drawings. Attached Figure Description

[0015] See the attached diagram. A high-altitude installation auxiliary device for a steel connecting plate. The auxiliary device includes: a left spindle 1, a right spindle 2, an elastic limiting sleeve 3, and a limiting sleeve control spring 4.

[0016] The elastic limiting sleeve 3 is respectively fitted onto the left spindle 1 and the right spindle 2 via the limiting sleeve control spring 4, forming an elastic connection structure in which the elastic limiting sleeve 3 slides on the left spindle 1 and the right spindle 2 under the control of the limiting sleeve control spring 4.

[0017] The left spindle 1 and the right spindle 2 form a threaded connection structure.

[0018] In use, the connecting plate 5 is connected to the steel profile 6 as a whole via this utility model. Moving the connecting plate 5 causes the elastic limiting sleeve 3, the left spindle 1, and the right spindle 2 to be in the following position. Figure 3 and 4 In this posture, the connecting plate 5 does not affect the hoisting of the steel section 6 to the installation position. After the hoisting position is completed, the connecting plate 5 is rotated to the desired position. Figure 1 After completing the bolt connection between the connecting plate 5 and the steel section 6, disassemble and separate the threaded connection between the left spindle 1 and the right spindle 2.

[0019] During the above process, under the action of the limit sleeve control spring 4, the elastic limiting sleeve 3 maintains the posture of the connecting plate 5 away from the groove of the steel section 6. The connecting plate 5 can rotate arbitrarily on the side of the steel section 6 after leaving the steel section 6, preventing the connecting plate 5 from affecting the steel section 6 entering the correct installation position. At the same time, it facilitates the connection and fixation of the steel section 6 after docking.

[0020] In this embodiment of the invention, to facilitate the disassembly and transport of the left spindle 1 and the right spindle 2, a ring 12 for disassembly is provided at the other end of the left spindle 1 and the right spindle 2. Various tools can be used to disassemble the left spindle 1 and the right spindle 2 through the ring 12.
