Third, the concept of aerial work:
1. What is aerial work? According to the technical specification for safety of high-altitude operation in building construction.
JGJ80-9 1
, the national standard "classification of work at heights"
(
GB/T3608-93
) regulation,
"
Fanzai
Falling height datum plane
2m
Above (inclusive)
2m
) Working at a height that may fall,
It's all called aerial work.
"
4. The difference between aerial work and aerial work:
(
1
)
Working at height: Working at height refers to working in buildings, equipment, workplaces and buildings.
Overhead operation of facilities, etc. , including climbing up and down during operation.
(
2
)
Aerial work: generally speaking, it refers to the space without supports at high places, and the height is normal.
It used to be very wide, boarding (sitting, riding, etc. ) in buildings and scaffolding, iron towers, poles and wells
All kinds of climbing tools, facilities and operations are called
"
work high above the ground
"
Actually, it's not true.
Cut it off.
(

)
Border operations:
Refers to the construction site working face edge without WeiDang or WeiDang.
Application height is lower than
80cm
Working at high altitude.
(

)
Hanging height operation:
It refers to carrying out without a foothold or a firm foothold.
Working at high altitude.
Four, high homework:
1. Climbing operations shall be carried out from the specified ramps or escalators, and it is forbidden to climb scaffolding poles.
Upper and lower tic-tac-toe frames or ropes,
It is not allowed to climb the boom or hanging basket with materials.
Go down.
2. Walking on high places or scaffolding,
Don't look around,
Don't let your body rest.
Lean against the railing, let alone sit on the railing and have a rest, let alone take a lunch break on the scaffold.
[14] Before using the steel plate, check whether there is any fracture or lack of small puzzles.
Before using bamboo frame board
Check for rot and fracture.
4. Before the scaffold is erected outside,
Or in the case that the outer wall is unprotected,
must not
Engaged in template installation and steel binding operations.
five
Before scaffold erection, the following calculations shall be made according to relevant regulations:
1
) the strength of flexural members such as longitudinal and transverse horizontal bars and the anti-sliding bearing capacity of connecting fasteners
Force calculation
2
) stud stability calculation
three
) Calculation of strength, stability and connection strength of wall parts.
four
) calculation of bearing capacity of stud foundation
If the calculation result is not within the allowable range, the installation scheme should be readjusted.
six
The erection of scaffolding must be coordinated with the construction progress, and the height of one erection shall not exceed the height of adjacent scaffolding.
Two steps above the wall.
seven
Scaffolding installation should extend from one end to the other, and gradually change the erection direction.
Not relative. Every step, we should correct the step distance, longitudinal distance and transverse distance according to the regulations.
And the verticality of the vertical pole.
eight
, base, plate should be placed on the accurate positioning line, plate length should be not less than.

Span, thickness not less than
50 mm
Wooden mats can also be made of channel steel.

, vertical pole, longitudinal horizontal pole, horizontal horizontal pole, vertical and horizontal sweeping pole, even wall parts.
Erection of poles, supports, lateral supports, etc. It should also meet the standards.
