Steel grating equipment should be inspected according to the drawings and planning requirements before inspection, and unqualified inspections should not be used in the project. It is necessary to determine the equipment sequence before the steel grating equipment, and combine the grid plate number of the drawing with the sequential equipment. It is necessary to lay the grid plate equipment process from the steel ladder of the structural layer to the periphery. After each equipment has a grid plate, it is necessary to fasten the fasteners (the number of equipment fixtures for each steel grid plate shall not be less than 2) or spot weld firmly. It is necessary to fix a mesh panel. It is not allowed to stand and operate the fixed grid plate, and it is not allowed to dismantle the temporary protection method. The steel grating shall not be piled up on the steel beam, and the piled height of the grating of the finished equipment shall not exceed 1.2m. Requires 100m of harness for grille operation and unconditionally fasten the harness to set the lifeline. During the operation, the operator should put small things into the bag, and it is not allowed to put small things and accessories (hand hammer, wrench, crowbar, welding rod, etc.) directly on the grille to avoid falling objects and hurting people. Before welding and corrective operations, fire prevention methods should be implemented to prevent fire or personnel from being burned. In principle, the laying of the steel grating does not allow the upper and lower layers or layers to cross together. If cross work is required, there must be a useful blocking device between the two working layers. During operation, the site should be cleaned up. During installation or dismantling, objects and severed metallic material shall not be allowed to accumulate near the grill opening. The leftover materials at the corners should be recycled in time to avoid impact and burns caused by falling objects. The equipment and pipelines under the grid plate path plate shall be connected with the corresponding auxiliary structure, and shall not be directly connected with the steel grid plate. If there are cut holes on the grid plate, the remaining area of the grid plate should be able to meet the requirements of the planned load. When there are large gaps on the grid plate, the bearing capacity of the grid plate needs to be reviewed. If the requirements cannot be met, auxiliary subbeams can be added around the opening, and fixed nodes should be added on the auxiliary subbeams if necessary. When confirming the size of the reserved holes passing through the pipeline on the grid plate, the influence of grid plate processing and equipment errors should be considered, and the influence of pipeline equipment errors should be considered together. If the piping is vibrating, other acceptable open spaces will need to be maintained. In order to avoid the risk of falling into the object communication grid plate. The grid plate shall not have a gap larger than the grid plate gap space, and the grid plate gap space shall not allow a sphere with a diameter of 35 mm to pass through and fall. When someone is moving under the operating route, the clearance of the grating plate shall not allow a 20 mm diameter sphere to pass through and fall, otherwise other appropriate means shall be adopted to ensure equivalent safety. When planning grid panels, an appropriate space should be reserved between the panel and the edge of the panel to the wall to avoid grid panels not functioning properly due to handling and equipment errors.
