Municipal construction engineering scaffold management regulations, scaffold for construction and erection of the feeding, feed and construction work with temporary structure frame, is an important auxiliary facilities of construction operations.
Many different kinds of scaffolding, according to the erection of position falls into two types: outside the scaffolding and scaffolding;
According to its structural form is divided into many force rod type, frame type and bridge type, hanging, hanging, lift, as well as the tool for operation between the layers scaffold, the materials used are wood, bamboo, steel pipe scaffold, generally adopts the A3 welded steel pipe, its status, development and perfection of our country construction scaffolding technology will have significant impact.
Are basic requirements of scaffolding, its width should meet the requirements of workers, materials storage and transport operation, strong stability, convenient installation, can be used repeatedly turnaround.
Structure is mainly refers to the operation layer, horizontal structure and vertical structure of three parts.
Layer is directly under the construction load, load by scaffolding to the small bar, and then to the beams and columns.
Transverse frame is composed of stud and a small bar, is directly under the scaffold and transmission part of the vertical load, it is the stress of the scaffold.
Longitudinal frame is mainly to enhance the overall stability of the scaffold.
In accordance with the regulations on the administration of construction engineering safety regulation, the greater danger of engineering includes seven categories: 2 version of the increase in 1) scaffold for construction project management regulations
Foundation pit supporting and precipitation engineering, foundation excavation depth is more than 5 m, or depth of not more than 5 m but complicated geological conditions and the surrounding environment, underground water level above the excavation surface engineering.
Conditions of excavation engineering, the excavation of foundation pit depth of more than 5 m (
The excavation engineering.
Template engineering: including tool template engineering (
Refers to the sliding mode, climbing form, templates, etc. )
Support system and special structure, horizontal concrete member template template engineering.
Scaffolding engineering: (1) more than 24 m floor type scaffold;
(2) adhesive lifting scaffolding;
(3) cantilever scaffold;
(4) doors scaffold;
(5) hanging scaffold;
6. Hanging basket scaffold;
7) remove the platform.
Demolition and blasting engineering;
Other projects: (1) prestressed tensioning construction;
(2) tunnel engineering construction;
3. Bridge engineering construction;
(4) special equipment engineering;
(5) over 6 m depth of slope engineering;
6 river diversion and closure engineering.
4, special construction plan write key points: 1)
Analysis of project size, characteristics and design intent adequately, seize the engineering features and difficulties.
Seize the engineering construction of the principal contradiction, making specific plan as the basis.
In special design and calculations for template bracket, foundation pit supporting, precipitation, auxiliary bridge construction, structures, open caisson, soft foundation treatment, prestressed tensioning, hoisting large components, concrete pouring, equipment installation and other kinds of construction, should according to the specification standard for structural stability, strength calculation, etc.
Construction method and construction technology for technical and economic comparison, for key links should be detailed analysis and demonstration, determine the process operation method, material requirements, technical quality control indicators and security measures, so as to guide the construction, considering the influence of seasonal construction at the same time, make the winter rainy season construction measures.
For evaluation of hazard identification and classification of engineering, the hazards classification management, must develop a feasible contingency plans for major risk sources.
Develop engineering deformation monitoring control, supporting monitoring and control measures, to ensure construction safety.
Engineering test, inspection methods and planning.
Formulate feasible safety measures.
