In the clean workshop, such as the operating room, the main focus of decoration is that the surface material is easy to install, easy to clean and easy to meet the cleaning requirements, which is conducive to maintaining indoor temperature and humidity and reducing the burden of air conditioning system. It is necessary to avoid explosion and fire of volatile narcotic drugs or gases caused by static electricity. In the clean workshop, it is necessary to prevent visual interference to medical staff and consider the applicability and feasibility of materials in construction.
1. Wall and ceiling practices of clean rooms such as operating room
The wall of operating room is composed of wall-shaped steel framework, including C-shaped groove keel, vertical main keel, horizontal keel, vertical auxiliary keel and top keel, all of which are processed by cold-formed thin-walled C-shaped steel. In the clean workshop, the wall, ceiling steel keel components and wall panel are processed and pre assembled in the factory according to the design, and then classified and numbered and transported to the construction site.
2. Wall panel installation
1) C-shaped floor trough (along the ground keel) is installed in the clean workshop, and the keel is fixed on the ground with expansion bolt according to the control line of ground keel.
2) After checking the position of the wall keel, assemble the keel framework of the single wall to the ground. In the clean workshop, the vertical main keel of the wall is connected with the horizontal keel and the top keel by bolts. Finally, all bolts are tightened to complete the single wall framework assembly.
3) The diagonal braces are used for temporary fixation, and then L-shaped and "- shaped connectors are used to fix the wall bone on the C-shaped ground keel. Finally, the connecting bolts are tightened in order to form an overall framework which is closed around. In the clean workshop, when the overall framework of the wall is installed and corrected, it is fixed with angle iron diagonal brace. One end of the diagonal brace is welded on the top keel of the wall, and the other end is welded on the embedded iron parts of the roof. At least 3 fixed points shall be guaranteed for each wall. Anti rust treatment shall be carried out in time for the welding spot.
In addition, the panel is suspended from top to bottom, and the same wall panel is suspended on two main keels. In clean Engineering, both sides of each panel shall not exceed the center line of main keel, and the joint of wall panel shall be 2mm. The two plates are connected by spot welding, each gap has 5-6 welding points, and the spacing is about 500mm. Anti rust treatment shall be carried out in time for the welding spot.
