Choosing the right method to cool the steel structure plant is a comprehensive problem. To solve it, it is necessary to take appropriate measures. First, we must find the key factors that affect the temperature of the steel structure plant, focus on its management, and deal with other relatively minor factors in a targeted manner. , In order to achieve a good indoor environment and its highest cost performance. We should consider the following questions in order to cool the steel structure workshop: What is the thermal insulation performance of the steel structure workshop? Does the steel structure workshop have a cooling system? How about the ventilation performance of steel structure workshop?
The steel structure workshop is ventilated and cooled. Because some machines in the steel structure workshop generate heat and water vapor, if these hot gases and water vapor are not exhausted in time, they will accumulate in the factory, thereby increasing the temperature of the steel structure factory and affecting the environment of the steel structure factory. The solution to these problems is to ensure reasonable ventilation of the plant and install a suitable amount of ventilation system. A reasonable installation of the exhaust system will significantly improve the air environment of the steel structure plant, and greatly reduce the temperature of the steel structure plant. Install roof forced exhaust fan, power fan is a kind of ventilation equipment driven by electricity.
The steel structure needs to be hung on the outside of the building with a vertical net. The staircase inside the building should not cover the opening of the side of the building, and a guardrail should be installed. For the component to be lifted, the water on the surface of the component should be cleaned first, especially the friction surface of the component should be cleaned, and the surface layer should be dry. In rainy and foggy weather, the supporting procedures for high-altitude hoisting and installation should be stopped, such as welding and compressing steel plates to wear high-strength bolt correction structures.
Before construction, the operation platform should be wrapped with flame retardant woven cloth around the column at a higher position than the welding joint, and the hole on the platform surface should be covered with asbestos cloth to prevent wind and welding slag splashing. For the welded seam after welding, the insulation work should be strengthened to avoid the brittle cracking caused by the sudden drop in the temperature of the weld seam. First, use asbestos cloth to wrap around the weld seam, and then wrap it with rock wool cloth. Before operation, remove moisture and impurities from the connecting parts of the connecting parts and keep the connecting surfaces clean and dry.
There are two types of fixing methods for the installation of color steel equipment: penetrating and concealed buckle. Penetrating fixation is the most common way to install color steel equipment on roofs and walls, that is, using self-tapping screws or rivets to fix the color plate on supports such as purlins. Penetrating fixation is divided into crest fixation, trough fixation or their combination . The side and end of the color plate overlap.
