What are the insulation measures for winter construction

This question is really a bit difficult, I recommend you to look it up on Google!

In the construction technical plan (measures) formulated, the following should be included: construction deployment Nawang (schedule), construction procedures, construction, machinery and materials deployment plan, construction personnel starvation technology training (temperature measurement personnel, admixture personnel) and labor plan, insulation materials and admixture material plan, operation points, quality control points, testing items and other aspects.

1) Production preparation: Arrange the construction tasks and on-site preparations according to the established schedule. Such as the insulation and anti-freezing of the on-site water supply pipeline, the insulation of the mixer shed, the leveling of the site and the setting of temporary roads, and the closure and insulation of doors and windows of the decoration project.

2) Resource preparation: Organize the preparation of admixture materials, insulation materials, construction instruments (temperature measuring agents), and labor protection supplies for employees according to the plan formulated.

The specific measures are as follows:

1. The formwork and insulation materials can only be removed after the concrete has cooled to 5.

2. When the temperature difference between the concrete and the outside is greater than 15, the concrete surface after demoulding should take thermal insulation measures to cool it slowly.

3. The initial curing temperature of concrete should not be lower than the specified temperature of antifreeze, otherwise thermal insulation measures should be taken. When the temperature is lowered below the specified temperature of the antifreeze, its strength cannot be less than.

4. Strengthen thermal insulation and maintenance, do a good job in the temperature measurement record of concrete curing, compare the internal and external temperature difference for each measurement, and take measures to strengthen thermal insulation in time when abnormalities are found.

5. For concrete mixed with antifreeze, it should be measured every 2 hours before the strength reaches 5n mm2, and every 6 hours thereafter.

6. Before pouring concrete, the snow, ice and insulation materials on the formwork and steel bars must be cleaned up.

7. In winter, at least two groups of specimens cured under the same conditions as the structure should be added for the sampling of concrete specimens, which is convenient for understanding the growth of concrete strength and conducive to the construction of on-site structures.

8. After the concrete is poured, do a good job of thermal insulation as required and make a temperature measurement record during the curing period according to the pre-buried temperature measuring pipe. During the curing period of concrete, it is necessary to prevent wind and water loss, and the thickness of the insulation layer at the corners should be increased to 2-3 times that of the outside of the face.

9. The concrete temperature measurement is arranged by a special person, and the temperature measurement table is reported to the relevant departments for archiving.

10. Commonly used admixtures are collected, configured and added according to the requirements.

11. The temperature and covering insulation materials in the process of concrete mixing, transportation, pouring, molding and curing should be thermally calculated.

12. The insulation and maintenance of the first pouring frame and platform adopts a layer of plastic cloth and 1 3 layers of straw curtain, and is tied firmly with 8 lead wires, and the number of straw curtain layers is determined according to thermal calculations to ensure that the critical strength is reached before freezing.

1. The radiator of the new house is properly deflated. Some home decoration to replace the new radiator, especially vertical and special-shaped radiators, the air and cold water in the radiator are not cleaned, and the heat dissipation effect will be greatly reduced.

2. Open the closed heating hood. Some people install a heating cover for the heater, and it is best to open the heat dissipation cover in winter, if it is opened to affect the appearance, the heat dissipation cover can be installed upside down, so that the shutter net is used upwards to dissipate the heat.

3. Install a reflective film behind the radiator. It can be installed between the radiator and the wall with an aluminum gusset with a metal surface, or a metal film for the stove used in the kitchen or a metal film for baking food, which can be installed between the radiator and the wall to keep warm and reflect the heating heat.

4. Install and replace sealing strips on doors and windows. The old-fashioned aluminum alloy doors and windows and steel windows have no sealing strips, and some new door and window sealing strips will have the problem of aging after a period of use, resulting in indoor heat loss.

5. Install thermal insulation curtains or thermal blankets on open balconies. If the closed balcony is changed into a room during the decoration, a set of warm curtains can be installed between the original balcony and the hall, and it can also play a role in indoor thermal insulation at night in winter. The floor can be carpeted, which can increase the thermal insulation effect of the floor.

Hello, it depends. If the amount is relatively small, it can be covered with film and rock wool, and hot steam can be introduced. If you are indoors, you can close the window and ventilate the area, and heat it with a heater or stove, and you can also use an iodine-tungsten lamp to increase the macro temperature.

Furnace insulation, but can not bake, affect the cement quality, winter preparation of concrete can be mixed with air-entraining agent to accelerate solidification, its purpose is to use concrete contains a large number of evenly distributed micropores, in order to slow down the freezing pressure of free water to the destruction of the capillary structure in the concrete, so as to improve its frost resistance, but the increase of air content will affect the compactness of concrete and the strength of cherry blossoms, should be controlled.
