Description

Technical Field

[0001] This invention relates to a protective installation method for the joint of steel frame components, belonging to the technical field of steel component construction structure. Background Technology

[0002] When the equipment room of the substation is built using a steel frame, sand particles from the tidal flat environment are blown by the air to the joint ends of the steel frame components. In the low temperature of winter, the sand particles are condensed by water vapor at the joint ends of the steel frame components, making them impossible to remove during construction. Therefore, after the steel frame components are erected and installed, the joint ends are covered.

[0003] The existing technology of covering the docking end is described in Chinese Patent Publication No. CN221314624U. Although the use of a bag can protect the steel strand and obtain force for installation through the magnetic steel plate, when the docking end is suspended at a high position of the steel frame, the magnetic steel plate and the bag fall uncontrollably when the connection is broken by removing the connection, which can easily cause safety hazards to the construction environment below. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a protective installation method for the joint of steel frame components.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a protective installation method for the joint of steel frame components, comprising: a controlled installation process in which the falling trajectories of the bottom support sleeve, the vertical part, the side sleeve A, and the side sleeve B follow the steel frame component.

[0007] The installation process specifically includes pouring a foundation at the construction site, simultaneously installing a bottom support sleeve, a vertical part, a side sleeve A, and a side sleeve B on the docking end so that the bottom support sleeve, the vertical part, the side sleeve A, and the side sleeve B wrap around and protect the docking end, and installing guide sleeves on the steel frame components.

[0008] The installation process also includes hoisting the steel frame components into an upright position and installing them onto the foundation, fixing them by connecting them with screws and nuts, so that the mating ends are protected and suspended on the steel frame components.

[0009] The installation process also includes untying the binding ropes A and B, allowing the side sleeves A and B to slide open to both sides, and the guide sleeve sliding down with the steel frame as the sliding guide. The guide sleeve pulls the side sleeves A and B through the pull rope, and the side sleeves A and B pull the bottom support sleeve down together through the connecting rope. The overall falling trajectory follows the steel frame and is thus controlled.

[0010] The beneficial effects of this invention are as follows: the guide sleeve slides down with the steel frame as the sliding guide, and the guide sleeve pulls the side sleeve A and side sleeve B through the pull rope. The side sleeve A and side sleeve B pull the bottom support sleeve down together through the connecting rope, so that the falling trajectory is controlled, which solves the problem that the falling trajectory of the magnetic steel plate and the bag is uncontrolled and easily causes safety hazards to the construction environment below.

Detailed Implementation

[0012] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0013] like Figures 1 to 4 As shown.

[0014] This application discloses a protective structure for the joint of steel frame components in a winter substation construction, comprising: The steel frame component 1 is installed on the construction site 12 via the foundation 11. The upper part of the steel frame component 1 is integrally and fixedly connected to the butt joint end 2. The two steel frame components 1 are distributed opposite each other at intervals. Later, crossbeams need to be installed on the butt joint ends 2 of the two steel frame components 1 for connection.

[0015] The bottom of the docking end 2 is equipped with a bottom support sleeve 21, which has a vertical part 22. The bottom support sleeve 21 and the vertical part 22 respectively contact the bottom surface of the docking end 2 for protection. Side sleeves A23 and B24 are installed on both sides of the docking end 2 respectively. Side sleeves A23 and B24 contact the side and top surfaces of the docking end 2 for protection. The top of the side sleeve A23 has a binding rope A25, and the top of the side sleeve B24 has a binding rope B26. The binding rope A25 and the binding rope B26 are bound and fixed together.

[0016] Both the side sleeves A23 and B24 are connected to both sides of the bottom support sleeve 21 via connecting ropes 3.

[0017] It also includes a guide sleeve 4 that can slide on the vertical steel frame 1. The guide sleeve 4, side sleeve A23, and side sleeve B24 are all made of wood, while the bottom support sleeve 21 and the vertical part 22 are made of packaging foam. The guide sleeve 4 is connected to the side sleeve A23 and side sleeve B24 on both sides by a pull rope 41.

[0018] After the side sleeves A23 and B24 are fitted over both sides of the mating end 2, they are secured by binding ropes A25 and B26. This allows the side sleeves A23 and B24 to pull on the mating end 2, providing support and preventing the bottom support sleeve 21, vertical part 22, and guide sleeve 4 from falling down. The mating end 2 is protected by the bottom support sleeve 21, vertical part 22, side sleeves A23, and side sleeves B24, preventing sand and condensation from forming on it during winter. When the mating end 2 needs to... When installing the crossbeam, the binding ropes A25 and B26 are untied, and the side sleeves A23 and B24 slide open to both sides. The guide sleeve 4 slides down with the steel frame 1 as the sliding guide. The guide sleeve 4 pulls the side sleeves A23 and B24 through the pull rope 41. The side sleeves A23 and B24 pull the bottom support sleeve 21 down together through the connecting rope 3, so that the falling trajectory is controlled. This solves the problem that the falling trajectory of the magnetic steel plate and the bag is uncontrolled and easily causes safety hazards to the construction environment below.

[0019] This application discloses a protective installation method for the joint of steel frame components, comprising: First, a hole is excavated at the construction site 12 and then the foundation 11 is poured. At the same time, the bottom support sleeve 21, the vertical part 22, the side sleeve A23, and the side sleeve B24 are installed on the docking end 2. The bottom support sleeve 21, the vertical part 22, the side sleeve A23, and the side sleeve B24 wrap around and protect the docking end 2. The guide sleeve 4 is installed on the steel frame 1. The steel frame component 1 is hoisted and installed on the foundation 11 in an upright state and fixed by connecting with bolts and nuts, so that the docking end 2 is protected by being sleeved and suspended on the steel frame component 1; When the crossbeam needs to be installed, the binding ropes A25 and B26 are released. The side sleeves A23 and B24 slide open to both sides. The guide sleeve 4 slides down with the steel frame 1 as the sliding guide. The guide sleeve 4 pulls the side sleeves A23 and B24 through the pull rope 41. The side sleeves A23 and B24 pull the bottom support sleeve 21 down together through the connecting rope 3. The overall falling trajectory is controlled along the steel frame 1.
