How to install the steel structure of large industrial workshop in the rainy season?

The steel structure industrial workshop is mainly built with steel structure, which is composed of steel beams, steel columns, steel pipes and other components. The center is generally connected by welding, bolts, rivets, etc., which is the main form of the building structure. When installing steel structures, we often encounter a situation where it rains, especially in the rainy season in summer. So how do we deal with the steel structure of large industrial workshop in the rainy season?

First, do a good job of rainproof measures for steel structure installation

Arrange special personnel to keep abreast of the weather forecast and grasp the rain meteorological data in advance. Arrange special personnel to conduct special inspection and management on the steel structure installation site of  large industrial workshop before the rain, especially the lightning protection measures should be carefully and carefully inspected in an all-round way.

1. Rainproof measures for formwork: When the formwork is stacked, the bottom layer must be overhead with the ground to prevent damage from rainwater immersion. In the formwork stacking place, effective ground drainage measures must be taken to prevent the accumulation of rainwater.

2. Rainproof measures for steel bars: The steel bars stacked at the installation site of the steel structure must be well drained to prevent rainwater from accumulating and soaking the steel bars.

3. Concrete rain-proof measures: during heavy rain, concrete pouring should be stopped, so that the construction joints should remain in a more reasonable position, and the drainage work on the construction site of the steel industrial factory should be done well. The concrete in the poured part must be covered with plastic sheet in time to prevent the change of the concrete mix ratio, reduce the concrete strength grade, and affect the project quality.

4. Rainproof measures for steel structures: According to the characteristics of construction in the rainy season, formulate corresponding technological measures, including the main technology of the project and the technology sensitive to climate.

5. Rainproof measures for scaffolding: Before it rains, check the fasteners of the scaffolding of the steel industrial workshop one by one. During the inspection process, you must first check whether the foundation of the scaffolding is firm. During the inspection process, the inspectors must ensure that their own safety protection measures are put in place, pay attention to anti-skid, strictly prohibit illegal command, and prevent falling.

6. Rainproof measures for temporary electricity: The leakage protection devices of various electrical appliances on the installation site of the steel structure workshop must be checked regularly, and the insulation outsourcing must be intact to prevent people from being injured by rainwater leakage. Welders, grinders and canopies set up outdoors should be placed on the upper part of the wire threader and other equipment, and the lower part should be supported by pads to prevent rainwater immersion. The power cord cannot be bare or plastic, and the power distribution box must be protected from rain. The metal skin of the electromechanical equipment must be reliably connected to zero protection, and the leakage protection device of the motorized switch box must be reliable.

Second, other safety measures that need to be taken at the construction site of the steel industry workshop

• 1. Regularly check that the anti-skid strips of the horse track are firmly tied to prevent accidental fall of the upper and lower personnel and reinforce the anti-skid strips.
• 2. Immediately organize manpower to rain on the floor, and clean up the water in the road and other places. Pay special attention to the fact that the scaffolding is slippery after rain, and the operator pays special attention to anti-skid and anti-fall.
• 3. Guardrails or warning signs should be set in potholes to prevent people from slipping.
• 4. The lightning protection device of the on-site freight elevator must be checked regularly during the rainy season.

Third, sanitation measures

1. In order to prevent the environment from being washed by rain and pollute the environment, thoroughly inspect all kinds of machinery at the steel structure installation site of large industrial plants before construction during the rainy season, and set up oil pans as required.

2. Clean up the garbage on site in time. If it cannot be cleaned up in time, be sure to cover the garbage to prevent it from being washed away by rainwater.

3. For the classification of toxic and garbage rooms, hazardous garbage must be collected in time.

4. In rainy days, wrap the steel members with plastic sheeting.

5. Be sure to pay attention to noise control during construction.
