Abstract

The invention discloses a hanging ladder type scaffold for installing a water-cooled wall spiral section and its erection method. The hanging ladder type scaffold comprises a plurality of bearing brackets and an annular channel; a climbing ladder is arranged correspondingly below each force bearing bracket; the erection method thereof includes steps of confirming overall length of the climbing ladders according to the height of the water-cooled wall spiral section; hanging the lower part along the upper part of the climbing ladders through a climbing ladder hook; hanging the climbing ladder and erecting a scaffold board and a protective railing along with the mounting of a water-cooled wall; carrying out construction by operators at the construction position nearby through the annular channel. Compared with the conventional erection methods, the method greatly decreases the cutting, polishing or welding work of a rooting point, and reduces the pipe injury by cutting and other quality risks while reducing the long-time overhead safety operation risk caused by erecting of an all-around scaffold; through replacing the conventional all-around scaffold by the hanging ladder type scaffold, the amount of turnover materials in use is greatly reduced, and the labor investment in erection and dismounting is reduced; besides, the economic benefit is significant.

Description

technical field

[0001] The invention relates to the technical field of boiler construction, in particular to a hanging-ladder scaffold for installing a spiral section of a water-cooled wall and an erection method thereof. Background technique

[0002] Boiler water wall installation is usually pre-assembled into several components on the ground, and then the components are assembled and installed on the boiler. Therefore, scaffolding on the components is a prerequisite for component installation. At this stage, conventional scaffolding basically adopts welded scaffolding and plug-in scaffolding, but the removal of scaffolding needs to build a whole house of scaffolding inside the furnace from the ash bucket section upwards, and then remove the scaffolding. When dismantling the scaffolding, it is necessary to cut the channel steel or inserting plate with flame. After cutting, it needs to be polished or sealed and welded. It consumes a lot of scaffolding pipes or measures. At ...
