Corner structure of scaffold apparatus

Abstract

The present invention relates to a corner structure of a scaffold device, which is installed to be newly constructed in order to secure a work space inside a hold of a liquefied natural gas carrier. According to the present invention, the corner structure of a scaffold device comprises: main and corner vertical posts having a few of connection parts installed on an outer circumferential surface atvertical intervals; a corner supporting truss having a rear end corner part connected and installed to the corner vertical post at a direction of 45 degrees; a three-stage truss horizontally connected and installed between the main and corner vertical posts; a clamp-shaped supporting truss to vertically connect and install a rear end part to the main and corner vertical posts; a corner extended support device coupled and installed to the upper part of the corner supporting truss and two clamp-shaped supporting trusses; a footplate installation flexible bar horizontally installed on the upperpart of the corner extended supporting device; and a footplate installation bar horizontally installed on the upper part of the two clamp-shaped supporting trusses.

Description

technical field [0001] The present invention relates to a corner structure of a scaffolding device, and more specifically, the corner structure that will be a corner support for a scaffolding device installed in a telescopic form in order to secure a working space inside a cargo hold of a liquefied natural gas ship It is integrated with the side support part on one side, and the horizontal and vertical support parts close to the cargo tank wall are provided in the horizontal and vertical directions of the corner structure in a telescopic manner. The corner structure is firmly supported, thereby increasing the strength of the corner structure, preventing the corner structure from sagging, and optimizing the distance between the front end of the corner structure and the wall surface of the cargo compartment, so that safe work can be performed. Background technique [0002] As a conventional invention, there is authorized patent registration No. 10-1412860 (title of the inventi...

Problems solved by technology

[0009] As mentioned above, only one corner portion of the corner support portion 6 configured as a quadrangular plate is connected to the column. According to this, even if it is not a heavy object, due to the continuous movement of the operator, the weight of the operator, the weight of materials, equipment, etc. It also sags, and its height is lower than that of the side support parts 4 and 5 on both sides adjacent to it. Therefore, there is a problem that the operator is tripped while moving while short ridges are generated.

[0010] In addition, among the first and second sliding rods 10 and 11 on which the pedals are placed, the three sliding rods 10a, 11a, and 11b have the same height, and one of the sliding rods is provided at the corner portion on the free end side opposite to the pillar joint 8. The height of 10b is lower than the above three sliding rods 10a, 11a, 11b, so the problem is that the pedals cannot be set on the first and second sliding rods 10, 11 on both sides at the same height, so the problem is, should the The lower one of the sliding rods 10b is provided with a separate support so that the height of the other three sliding rods is the same as that of the remaining three sliding rods.
