3.The lifting commander should strictly implement the hoisting safety operation procedures.

4.Before the formal lifting should be carried out test lifting, check the force of all the tools during the test lifting, and if the problem is found, the workpiece should be put back to the ground first, and the trial lifting should be re-tested after troubleshooting, and everything can be confirmed to be normal before formal lifting.

5.In the process of hoisting, if there is a failure, it should be reported to the commander immediately, and no one shall leave the post without instructions.

6.Before lifting heavy objects in place, it is not allowed to untie the hoisting rigging; No one is allowed to lift or lift with the hoisting equipment or hoisting equipment.

7.It is strictly forbidden to carry out hoisting operations when the wind speed is above 5.

8.It shall not be hoisted in rainy and foggy days; In the hoisting process, if it is interrupted for any reason, safety measures must be taken, and the equipment or components must not be suspended overnight.

9.The position where the lifting object falls must be supported with square wood or other materials to ensure that the wire rope is smoothly extracted after the object falls.

3) The lifting operation is completed.

The slings and spreaders are retracted and placed in the specified place, and they are inspected and maintained.

2. Preventive measures for lifting and hoisting accidents.

1.When transporting objects to the ground from high altitudes, they should be tied up with ropes and hung down. When hoisting, it is not allowed to stack or hang sporadic objects on the components.

Sporadic materials and objects must be tied firmly with cages or wire ropes and safety ropes before they can be lifted and transmitted, and materials and objects and tools must not be thrown at will to prevent slipping and injuring people or accidents.

2.The component must be tied firmly, the lifting point should pass through the center of gravity position of the component, and the lifting should be stable to avoid vibration or swing.

3.When lifting components, the speed should not be too fast, should not stay at high altitude for too long, and it is strictly forbidden to rise and fall sharply to prevent the components from falling off.

4.Before the component is temporarily fixed after being in place, the hook shall not be loosened and the hoisting rigging shall be unfastened. After the component is fixed, the connection should be checked firmly and stable, and when the connection is determined to be safe and reliable, the temporary fixing tool can be removed and the next step of hoisting.

5.It is strictly forbidden to hoist in wind, snow, frost and fog and rainy days, and there should be sufficient lighting for night operations.

Chapter 119 Zhongxiang Kui Baoyu But the Dust Fate Mu Huang Enjia Yan Shize Chapter 120 Zhen Shi Yin said in detail that it was too vain Jia Yucun boiled down to Dream of Red Mansions [1].

The walls are glass, and the town can also be considered a glass laughing curtain wall. The glass curtain walls are transported to each floor by high and floored freight elevators, and then manually transported to the use site by glass suction cups.

1. Instructions for the installation method of hanging the exterior wall.

The national standard 40*40*4 galvanized angle iron frame is used to connect with the wall or window plate bolts, and the rubber between the air duct and the angle iron frame is cushioned with anti-vibration, and all gaps are sealed with glass glue or cement mortar. The air supply elbow should be done according to the requirements of the drawings, and the cross-sectional area should not be less than square meters. When installing the air duct, the boom should be installed on the installation base frame, so that all the weight of the air duct is hoisted on the base frame.

Technical requirements: 1. The welding and installation of the triangle bracket should be firm;

2. The maintenance platform must be able to support the weight of the unit and maintenance personnel;

3. The host installation must be horizontal;

4. The cross-section of the main engine flange and the air supply elbow must be flush;

5. All exterior wall air ducts should be waterproofed;

7. A waterproof bend should be made at the elbow of the air duct to prevent water from flowing into the room.

2. Instructions for the installation of iron tile roofs.

1. The roof truss should have sufficient strength to bear the weight of the unit and maintenance personnel;

2. The size of the roof opening should not be greater than the installation size of the air duct 20mm;

3. The installation must be horizontal;

4. The cross-section of the main engine flange and the air supply elbow must be flush;

5. All zinc-iron tile air ducts must be waterproof to prevent water leakage;

6. The four corners must be supported by a support frame.

Third, the brick wall structure of the roof installation method of the factory building technical requirements:

1. The 40*40*4 angle iron frame is connected and fixed with reinforced concrete bolts;

2. The roof truss should have sufficient strength to bear the weight of the unit and maintenance personnel;

3. The size of the roof opening should not be greater than the installation size of the air duct 20mm;

4. The installation must be horizontal;

5. The cross-section of the main engine flange and the air supply elbow must be flush;

6. All roof air ducts should be waterproofed;

7. The four corners must be supported by a support frame.

There are three main ways to install signboards at high altitude:

Method 1: When the area of scaffolding is relatively large, it is more convenient to use this method.

Method 2: The crane lifts, the area is not very large and it is installed as a whole, this method is generally good.

Method 3: Spider-Man hoisting, there is also a type of installation of independent signboard words generally used Spider-Man hoisting.

These three methods are also flexible to use, sometimes all three can be used, but the first method is generally used as much as possible, and the work is much more, but the safety hazards are smaller.

Telecom broadband, Unicom broadband, and mobile broadband can be installed in Tianjin, but it is best to install telecom broadband.

Here are some details about telecom broadband:

In 2015, the latest Tianjin Telecom government and enterprise Internet private line tariffs**, the following are the group's unified signing channels**:

The above is the group's product package fee, and the following special circumstances are as follows:

1. In some areas, the office building does not enjoy the preferential scope.

The 10m exclusive product package has an annual payment discount of 30,000 yuan, and the 20m exclusive product package has an annual payment discount of 50,000 yuan per year.

2. Binhai New Area (including airport and Tanggu) Only some areas can implement the above tariffs, and most areas can be found here: Tianjin Telecom Optical Fiber Dedicated Line - Government and Enterprise Customers**.

3. Some office buildings, commercial buildings and parks.

Due to the other costs of communication operators stationed in office buildings, commercial buildings and parks, the access costs often vary widely, and the above ** often cannot be implemented.

Fourth, Wuqing District.

Wuqing District can implement a 10m exclusive 42,000 yuan annual preferential program.
