Description

Truss top plate dismantling device and method {THE UPPER PART OF TRUSS DISMANTLING DEVICE AND METHOD}

The present invention relates to a truss top plate disassembly apparatus and method, and more specifically, to remove the truss top plate in one operation by using a plurality of pulleys, the truss top plate disassembly that can improve the work efficiency and ensure safety An apparatus and method are provided.

In general, in the case of manufacturing a large structure or a large tank for ships, the scaffolding device is installed inside or outside, and then the work is performed.

Here, the scaffolding device is a temporary temporary installation to be able to work at a high place during construction, and serves as a foothold for material transport or passage of work personnel and work.

These scaffolding devices are divided into scaffolding devices for external works installed outside of large structures for work of large structures such as buildings, and scaffolding devices for internal work installed for internal work of large structures for ships such as pressure vessels, tanks, and domes. These are somewhat different in the form of work, installation structure and the like.

The scaffolding device as described above forms a floor-by-layer structure in which support pillars and work scaffolds are assembled and laminated to safely support the load of the work force, the load of the material, etc. according to the size of the structure to be installed.

On the other hand, the scaffolding device is supported by a support having a truss structure, the support consists of a top plate, a bottom plate and both side walls.

Here, the truss structure is a structure that is connected to both ends of the two or more linear members coupled to the triangular space, the structure for efficiently supporting the load force by the operator and the worker material.

The reason why the truss structure is composed of the triangular unit space is that when the members are constituted by the triangular space, even though the connection points of the members are the rotating ends, the truss structure becomes a more stable form than the rectangular space.
