Things to note when constructing exterior wall insulation materials during the rainy season

Precautions for the construction of exterior wall insulation materials in the rainy season

1. Storage of molded polystyrene boards

If the construction site conditions permit, please store the insulation boards indoors, or stack them in the leeward direction of the building, cover them with sunshade nets, and compact them with heavy objects , to prevent strong winds from blowing away the insulation boards and causing unnecessary economic losses.

2. Mesh cloth storage

Should be stored in a dry and ventilated house to prevent It maintains good workability.

3. Storage of polymer mortar

When storing polymer mortar, you must pay attention to waterproofing and moisture-proofing .

① Indoor storage: When construction site conditions permit and there are not many existing polymer mortar products, materials can be stored indoors. In order to prevent the impact of increased air humidity on materials caused by rainy weather, indoor windows should be sealed to prevent rain. The materials are stacked 30 centimeters above the ground and covered with raincloth to prevent water from accumulating upstairs due to rainy weather and leaking onto the storage materials, causing the polymer mortar to harden.

② Outdoor storage: Choose a high-lying place to stack materials. The surrounding area has smooth drainage and is not prone to water accumulation, and it should be at least 30 cm above the ground. Before stacking, lay a layer of raincloth on the material platform to prevent moisture. After stacking, cover it with a complete raincloth, tie it with a rope, and use heavy objects to tighten the surroundings of the raincloth. Pay attention to weather changes, wait until it is sunny, open the raincloth to dry, evaporate the water in the raincloth, and avoid water vapor to produce water droplets, which will drip on the polymer mortar and cause hardening.

4. Storage of facing materials and glue

Place them in the shade and in After the construction is completed, inspect and pay attention to whether the lid of the bucket is properly closed to prevent rainwater from entering the bucket and causing quality problems in subsequent construction.

5. Precautions for construction machinery:

Exterior wall insulation construction mainly uses construction cages , when rainy days come, construction is prohibited, the power supply of the cage is cut off, and the motor is covered to avoid short circuit and danger caused by water intrusion due to rain. When work resumes after rain, professionals should be sent to inspect the cage to prevent cage failures and dangers.

6. Precautions for thermal insulation construction

① Pay close attention to the weather forecast, give early warning, and be reasonable Schedule construction time.

②Windy weather: In case of strong winds above level 6, no work at height is allowed. Strengthen safety education for workers and conduct strict inspections on workers’ use of safety belts, safety helmets, and safety ropes.

③Construction is prohibited on rainy days. According to the specific weather conditions of the day, the construction process will be reasonably arranged. For example: to prevent the protective surface layer from being newly constructed and not strong enough. After being washed away by rainwater, the surface flatness and plastering thickness will not meet the standards and rework will occur, which is time-consuming, labor-intensive and material-intensive.

7. Precautions for veneer construction

① Follow the construction completion surface, within 24 hours It will not be washed away by rain.

② Depending on the wind strength, try not to carry out spraying materials construction to avoid uneven spraying and contamination of other completed surfaces.

8. Safety precautions

① Strengthen safety education and training for all workers at the construction site Work, especially the details that are easily overlooked, makes safe construction deeply rooted in the hearts of every worker.

②Safety inspection must be in place. Conduct regular inspections of the main body of the building, scaffolding, hanging baskets, and construction electricity to detect problems as soon as possible and eliminate them in a timely manner, repair damaged areas in a timely manner, and handle problems in their bud. In order to ensure that the construction proceeds smoothly and high-quality projects are made. It is hoped that all construction units and agents will take preventive measures, arrange construction reasonably, and avoid material waste.
