In the construction process of rural self-built houses, concrete pouring is a key link. Concrete is an important part of the structure of a house, and its quality directly affects the safety and durability of the house. In the process of concrete pouring, it is necessary to pay attention to the pouring of formwork, vibration and plastering to ensure the compactness and surface flatness of the concrete.
1. Pour the template.
Before concrete pouring, the fabrication and installation of the formwork is crucial. It is necessary to ensure that the size, flatness and stability of the formwork meet the requirements to ensure the forming effect of concrete. When pouring into the formwork, it is necessary to control the slump of the concrete to avoid affecting the compactness and surface quality of the concrete due to the slump being too large or too small. At the same time, it is necessary to ensure that the concrete is fully filled with the formwork to avoid cavities or accumulation.
Second, vibrate. Vibrating is an essential step in the concrete pouring process. Through vibration, the concrete can be made more compact, internal bubbles and cavities can be reduced, and the compressive strength of the concrete can be improved. When vibrating, it is necessary to choose the appropriate vibration equipment, control the vibration time and intensity, and avoid over-vibration or leakage vibration. At the same time, it is necessary to pay attention to the position and depth of the vibrator to ensure that the air bubbles inside the concrete are fully discharged.
3. Smoothing. Troweling is an important step after the concrete pouring is completed. By troweling, the water leakage and floating slurry on the concrete surface can be removed, making the surface more flat and smooth. At trowel leveling, it is necessary to choose the appropriate trowel tool, control the number and strength of trowel, and avoid surface scratches or trowels. At the same time, it is necessary to pay attention to the ambient temperature and humidity of the trowel level to avoid affecting the hardening process of the concrete due to too high or too low temperature.
In short, in the process of pouring concrete for rural self-built houses, pouring formwork, vibrating and smoothing are the key links. It is necessary to strictly control the construction process to ensure that the compactness and surface flatness of the concrete meet the requirements to improve the safety and durability of the house. At the same time, it is also necessary to pay attention to construction safety and quality monitoring, find and deal with problems in a timely manner, and ensure construction quality and safety.
