Scaffolding Erection Procedure for ECU/LCI Steel Structure
ECU/LCI钢结构安装脚手架搭设方案


一、搭设原则Building Principle:
确保施工作业人员的安全操作。在保证人身安全的情况下,考虑梁柱等吊装作业的通道和安装的方便性,以及脚手架搭设的简便。
Ensure safe operation of construction personnel, and pursue to the convenience of access of lifting activities (beam, column, etc.), installation and scaffold building in itself with the priority of safety.
二、脚手架的搭设方式Building method of scaffolds:
1、管廊、ECU钢结构管架吊装、安装搭设脚手架型式
The scaffold type for lifting and installing steelwork on the Bench and ECU
:钢结构地面成榀,在榀的两侧绑扎铝合金梯子,在榀的顶梁上面安设生命绳(14mm)挂搭安全带。
a. Note: the steel structure is assembled as one unit on the ground; ladders of aluminum alloy are fixed on the two sides of the assembling unit; and safety rope is set on the top for safety harness.
:
The building type of ladder and safety rope is as follows:
防坠落器
防坠落器
生命绳
生命绳扣
,使用4根封绳拉紧(若需要,加设倒链),进行找正和固定。
c. Straighten and fix the assembling unit with four wind ropes pletion of placement, if necessary, set hoisting block.
(、2m长)单独制作,作为挂搭安全带使用(当安全带挂绳直接挂搭横梁不够长时使用)。当横梁间距大于3m时,每根横梁上面仍使用生命绳(虚线)。
d. Fabricate safety rope and button with dimension of ×2m separately for safety harness, specifically, when the safety harness is not long enough to hang on the beam. When the space between vertical beams is more than three meters, it also will be used. (Dot line)
2、高空地脚螺栓处,沿混凝土梁搭设操作平台的型式:
Building type of platform along concrete column on the anchor bolt at height:
3、焚烧炉混凝土框架内梯子、平台施工脚手架搭设型式:
Scaffold building type of ladder and platform in the concrete frame of incinerator:
:由地面往上直接搭设或采用人可搬动式组架。
For the scaffold relatively low off the ground, build it from the ground directly or adopt the movable frame.
,在立柱周围的脚手架型式,以抱箍的方式往外延伸,具体型式如下:
b. For the scaffold close to columns, build it by hooping the column and expanding outside. The building type is as follows:
