A marine temporary railing column and its installation and use method

Abstract

The invention discloses a temporary railing column for ships, which comprises a column, a column sleeve, a cross base and a spring, the column sleeve is a hollow circular tube, and the bottom of the column sleeve is fixed on the middle part of the upper surface of the cross base. A number of bolt holes are provided on the column casing, the column is sleeved in the column casing, the column is fixedly connected to the column casing by bolts, and the upper plate of each cross side of the cross base A wedge-shaped block with a narrow top and a wide bottom is fixed on each surface, and a spring is fixed in the middle of the lower surface of the cross base; the invention also discloses a method for installing and using a temporary railing post for a ship. The invention has the advantages of convenient installation and disassembly and high system safety.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a temporary railing post for a ship and a method for installing and using the same. Background technique [0002] At present, in order to avoid the danger of personnel falling at the edge of the section or the large opening during ship construction, temporary protective railings are required. There are usually two fixing methods. One is to use on-site welding to temporarily weld the railing columns to At the fence; there is another way to use a threaded chuck, using a special clamp to clamp the railing post on the steel plate at the edge of the segment or at the opening. Although these two methods can meet the requirements of ship construction, after analysis, it is found that the traditional methods have the following shortcomings: [0003] 1. The on-site welding of railings requires the cooperation of welding machines and other equipment. The preparation time and welding time are l...

AI Technical Summary

Problems solved by technology

[0003] 1. On-site welding of railings requires the cooperation of welding machines and other equipment. The preparation time and welding time are long, and the outdoors will be restricted by rain and snow, which will affect the construction progress.

[0004] 2. During the welding of temporary railings and the subsequent dismantling by gas cutting, the high temperature generated will damage the coating of the deck, increasing the difficulty of coating protection

[0005] 3. The railing column in the form of a fixture must be installed at the edge of the steel plate, and during the installation and removal process, the construction personnel must be in the dangerous area on the edge of the opening to tighten (loosen) the fastening bolts, and the process itself has certain safety hazards
