11)All matting fence removal, should be from the outside to the inside of the erection, handling, to prevent from the inside to the outside of the turn up, fence surface garbage objects directly from the height of the fall injury.

12) scaffolding must use welding gas cutting process, should be strictly in accordance with the national requirements of special trades and fire regulations. Additional staff, equipped with hoppers (buckets), to prevent sparks and cutting material spattered, strictly prohibit the use of welding and cutting tools without a license.

13)After the completion of the day, should carefully check the situation around the post, such as found to leave hidden parts, should be repaired in a timely manner or continue to complete to the end of a program, a part of the end before you can leave the post.

14)All poles, fasteners and other objects conveyed to the ground should be stacked and organized according to category.

3.indoor full hall scaffolding erection project safety technology delivery

1)Indoor full hall scaffolding erection should be strictly according to the requirements of the construction organization design erection.

2)The longitudinal and transverse distance of full-height scaffolding should not be more than 2m.

3)The full-height scaffolding should be set up to ensure the safety of operators.

4) operation layer should be full of bamboo fence, shall not leave a hole. Must leave a hole, should be set up to protect the fence.

5)Large bar-shaped scaffolding, operation of both sides of the step layer, should be protected by guardrails.

6)The distance between the scaffolding steps should be controlled in 2m, must be higher than 2m, there should be technical measures to protect.

7) full hall scaffolding stability, should be used to diagonal bar (scissor brace) protection.

8) full hall scaffolding should not be used steel, bamboo mixed.

4.elevator shaft shelf, safety net erection project safety technical communication

5. Acceptance and maintenance of scaffolding

Scaffolding acceptance criteria:

Any kind of scaffolding should be built in accordance with the order of erection, section, row, or acceptance after completion of erection. Acceptance by the project construction unit is responsible for convening by the technology, security department and erection team *** with, check whether it is in accordance with the drawings, the relevant norms of construction. Acceptance can be carried out according to the following points:

(1) scaffolding bottom foundation is stable.

(2)Whether the scaffolding columns, big crossbar is horizontal and vertical.

(3) Whether the scaffolding soft and hard ties are firmly pulled layer by layer.

(4) Whether scissor braces of scaffolding are fully covered.

(5) Whether there is any remaining material in the scaffold row layer.

When necessary, random sampling can also be used to accept the method of measurement, qualified to fill out the acceptance form, signed and filed, which can then be listed for use.

Maintenance work:

Scaffolding in building construction is responsible for stacking materials, for horizontal transportation channel as well as safety protection of construction personnel and other important tasks, so when the erection is completed and after acceptance and put into use should be frequent maintenance. Because most of the scaffolding is used in the open air, coupled with the construction cycle are generally longer, long-term sun and rain, construction of various situations caused by damage, making the scaffolding rod damage or tilt, so that the security is greatly reduced. Therefore, scaffolding in the use of the period, should establish a normal maintenance system.

Maintenance work generally has two ways: divided into daily full-time maintenance and maintenance during the holiday shutdown. Full-time maintenance workers have the obligation to publicize the use of scaffolding to the use of team norms and supervision and daily maintenance. They should always check the integrity of scaffolding poles, fasteners, tie points and ligatures, etc. If there is any damage, they should be repaired in time to ensure safe production.
