At noon on May 23, a scaffolding collapse accident occurred on the top floor of a construction site in mabugang Town, Longchuan County, Heyuan, which resulted in the fall of construction workers
.
Eight people died and one was slightly injured
.
Scaffolding is an essential facility in construction, and scaffolding collapse and fall accident is one of the frequent accidents in the construction industry in recent years
.
The main causes of the accident are various, such as non-standard scaffold erection, overweight load on the scaffold in construction, random removal of tie or stress bar, etc
.
may cause safety accidents
.
Therefore, it is very important to strengthen the safety construction management of scaffold
.
Since this year, several scaffold collapse accidents have occurred
.
① in Xiangyang, Hubei Province, on the morning of April 15, 2020, the scaffold collapse accident occurred in the safety passage of building 11, Xiangyang Tianxia, Fancheng District, Xiangyang City, Hubei Province, causing seven people injured
.
② On the afternoon of March 24, 2020, a scaffolding collapse occurred at a construction site in Macao, killing three workers and injuring four
.
③ At noon on January 7, 2020 in Bozhou City, Anhui Province, a scaffold collapsed suddenly, and many cars, electric vehicles and motorcycles were crushed
.
It is understood that the collapsed scaffold is about 40 meters long
.
What’s more frightening is that the steel pipe of the scaffold also went through the windshield and directly inserted into the interior of some cars
.
According to residents nearby, the whole process of scaffold collapse was only about 2 seconds
.
④ At about 15:30 p.m
.
on January 5, 2020 in Wuhan, Hubei Province, a major construction collapse accident occurred in the first phase of Wuhan Baden city ecological leisure tourism development project, located at No
.
1 Tianzishan Avenue, Jiangxia District, Wuhan City, causing 6 deaths and 5 injuries
.
Control scaffold safety “ten passes” material quality, select materials in strict accordance with regulations, quality and specifications
.
The dimensions must be set up according to the specified spacing
.
The planking and scaffold boards must be fully paved without gaps, probe boards and springboards, and the sundries on the boards shall be removed frequently
.
1.2m high railings or vertical safety nets must be set outside the scaffold and on both sides of the ramp
.
Cross bracing and support must be set up according to the regulations, and must be firmly connected with the building
.
The load-bearing scaffold is evenly distributed
.
The structural frame should be controlled at 270Kg / m2, the decoration frame should be controlled at 200kg / m2, the load of other frames must be determined by calculation and test, and the load of standard frame should be determined in strict accordance with the regulations
.
It is necessary to set up a raceway or ladder for workers to go up and down the shelves
.
Construction personnel are strictly forbidden to climb up and down from the shelf to prevent accidents
.
For lightning protection, a certain safety distance should be kept between the metal scaffold and the transmission line, or isolation and protection measures should be set up
.
Generally, wires shall not be directly bound on the shelf
.
If they have to be bound, they shall be isolated by padding wood
.
If the metal foot binding is higher than the surrounding lightning protection facilities, a plan shall be made to reset the lightning protection system
.
In addition to the processing according to the regulations, the cantilever suspended basket is set in strict accordance with the scheme
.
All kinds of shelves must be checked and accepted by the technical and safety departments after they are put into use
.
During use, it should be checked frequently and problems found should be handled in time
.
Video sharing: safety construction technology points of scaffold operation this video interprets the safety construction technology points of scaffold operation in detail from the aspects of safety management requirements, construction preparation requirements, basic requirements for erection of various scaffolds, inspection and acceptance requirements, demolition requirements, etc., which is worth learning: scaffold collapse often causes serious casualties and accidents Property loss, tighten the safety net of the scaffold, every detail should not be careless, and operators should not forget to take relevant protective measures when working on the scaffold!
