It takes more than a few degrees to hit the cast-in-place roof in winter.

According to GB 50666-201KLOC-0/Code for Construction of Concrete Structure Engineering, the temperature of concrete mixture entering the mold should not be lower than 5℃ and higher than 35℃. When the average temperature of the day reaches above 30℃, measures should be taken according to the requirements of high temperature construction. The standard construction temperature is 5℃ ~ 35℃ ~ If antifreeze is added, the winter construction temperature is-15℃. Concrete pouring temperature, that is, after the concrete is vibrated and before the upper concrete is covered, measure the temperature below the concrete surface 10cm, and after the concrete is vibrated and before the upper concrete is covered, measure the temperature below the concrete surface 10cm.

What should I pay attention to when building a house in winter?

1, building materials. Building materials purchased in winter should not be placed in the open air, and the surface of building materials should be coated with clear oil to prevent wind cracking and deformation. Before construction, the wood should be placed in the heating room for 35 days to make the water fully volatilize, reduce the moisture content of the wood and prevent cracking and deformation.

2. paint. In general, the ambient temperature of the coating should not be lower than 5℃; The ambient temperature of common mixed color paint should be above 0℃, and the ambient temperature of varnish should not be lower than 8℃.

3. Accessories. Sand should be sieved to remove ice before use. When mixing mortar, the water temperature shall not exceed 80℃.

4. Fire prevention. It's very dry in winter, and there are many combustible materials on the construction site. Therefore, attention should be paid to fire prevention, careful use of heating equipment, waterproof use of blowtorch and so on. The construction site should be equipped with fire control facilities.

5. Construction process. When building a wall, the ice or frost on the brick surface should be removed first, soaked in water to make it properly wet, and the temperature of the mixing mortar should not exceed 80 degrees Celsius. Walls also need to be covered with grass curtains to keep warm. Also avoid construction in rain and snow.

6. Keep warm. The ways to keep warm in decoration are: cold method and hot method. The cold method needs to add antifreeze to the raw materials. Thermal method is to use the permanent heat source in the house to improve and maintain the temperature of the operating environment; This can ensure that winter construction will not cause losses and will not affect the quality of the house.

7. The construction is completed. After the house is renovated, it is not advisable to move in immediately. Indoor doors and windows should be opened and ventilated for at least one week, so that harmful substances released by furniture, carpets and wall paint can be discharged, otherwise it will affect health. Also pay attention to maintaining indoor humidity to prevent walls and furniture from cracking because the air is too dry.

How many degrees does it take to hit the cast-in-place roof in winter? What should I pay attention to when building a house in winter? Have you found the answer after the above description? Building a house is relatively common, and you can rest assured only by building a house in the right way. When building a house in winter, people pay great attention. People must avoid all kinds of problems through careful understanding.
