Qingdao Yili Steel Structure Manufacturer should arrange a special person to keep abreast of the climate forecast and grasp the rainy and climatic data in advance. Arrange a special person to check the on-site special items before the rain. For the places that do not meet the rain prevention measures or the standards are not standard, it is necessary to order subcontracting and rectification within a certain period. Especially with regard to the lightning protection measures, it is necessary to carefully and carefully conduct a full-scale review. Pay attention to the rain protection of the following parts:
prevent rain in the construction of steel structure project
Protect the steel bars placed on site for a long time from rain and hide to avoid serious corrosion of the steel bars. Rebar storage site must have unobstructed drainage to avoid rainwater deposition and immersion of corroded steel bars.
In principle, the welding of steel bars is suspended in rainy days. If welding is encountered in special circumstances, it is necessary to have rain-proof measures to avoid the rain.
2. Steel structure template rainproof
When the formwork is stacked, it is necessary for the base layer to be elevated above the ground to avoid damage by rainwater immersion. In the formwork accumulation area, it is necessary to have effective ground drainage methods to avoid rainwater siltation.
When the formwork is constructed on a rainy day, it is necessary to leave a cleaning port or water outlet for the beam and wall formwork. After the formwork release agent is painted, the plastic cloth should be covered to prevent the isolation layer from being washed away by rain. It is necessary to reapply the formwork isolation layer after being washed by rain before closing the mold.
3. Steel structure concrete rainproof
In case of heavy rain, the pouring of concrete should be stopped to keep the construction joints in a more reasonable position, and the site drainage work should be done. It is necessary to cover the plastic in the concrete that has been poured in time to prevent the concrete cooperation ratio from being changed and the strength level of the concrete to be reduced. Affect the quality of the project.
Before pouring concrete, it is necessary to clean the dirt and water in the formwork before pouring concrete.
4. Steel structure scaffolding rainproof
It is necessary to check the fasteners of the scaffold one by one before and after the rain, and it is necessary to check whether the foundation of the scaffold is strong during the inspection process. During the inspection process, the construction and inspection personnel must ensure that their own safety protection measures are in place, pay attention to anti-skid and anti-drop, and prohibit violations of command.
5. The steel structure is near electricity and rain
Leakage maintenance equipment for various electrical appliances is necessary to be active, regularly check various construction wires, insulation outsourcing is necessary to be intact and damaged, to avoid injury from rainwater leakage; outdoor welding equipment, grinding machine, threading machine and other equipment above A rain canopy should be erected, and the lower part adopts a cushion method to avoid rainwater soaking.
