How to prevent rain in the construction of steel structure manufacturers in rainy days

For the construction of steel structure manufacturers, special personnel should be arranged to understand the climate forecast in time and grasp the rainy climate data in advance. Arrange special personnel to inspect and handle the special on-site before the rain. For places that do not meet the rain protection measures or the measures are not standard, it is necessary to order subcontracting and rectification within a necessary period. In particular, the lightning protection measures must be carefully and carefully inspected in an all-round way. Attention should be paid to the rain protection of the following parts:

1. Rebar rainproof Hide the steel bars that have been placed on site for a long time to avoid serious corrosion of the steel bars. There must be unobstructed drainage in the rebar accumulation yard to avoid rainwater silting and soaking the corroded rebar. In principle, the welding of steel bars should be suspended in rainy days. If welding is carried out in special circumstances, it is necessary to have rain-proof measures to prevent the welding joints from being wetted by rain, resulting in changes or declines in the mechanical properties of steel bars, which will affect the quality of the process.

2. When the formwork rain-proof formwork is piled up, it is necessary that the base layer be raised above the ground to avoid damage from rainwater soaking. In the formwork accumulation, it is necessary to have effective ground drainage methods to avoid rainwater siltation. When the formwork is constructed in rainy days, it is necessary to leave a cleaning port or a water outlet for the beam and wall formwork. The formwork isolation layer washed by rain must be repainted before closing the mold.

3. Concrete pouring should be stopped in case of heavy rain, so that the construction joints should remain in a more reasonable position, and the site drainage should be done well. The concrete must be covered with plastic sheet in time to prevent changing the concrete ratio, reducing the strength level of the concrete and affecting the quality of the project. Before the concrete is poured, it is necessary to clean the dirt and water in the formwork before pouring the concrete.

4. Before and after the rain, it is necessary to check the fasteners of the scaffold one by one, and in the inspection process, it is necessary to first check whether the foundation of the scaffold is firm. During the inspection process, the construction and inspection personnel must ensure that their own safety protection measures are implemented in place, pay attention to anti-skid, anti-fall, and prohibit illegal commands.

5. It is necessary to activate the leakage maintenance equipment of all kinds of electrical appliances in case of electricity and rain, check all kinds of construction wires regularly, and the insulation outsourcing must be intact and without damage to avoid damage caused by Rainwater leakage can hurt people; outdoor equipment such as electric welding machines, grinding machines, threading machines and other equipment should be set up with a canopy, and the lower part should be supported by pads to avoid rainwater soaking.
