1. Be sure to carefully check whether the EPS sandwich insulation module is staggered and spliced, avoid vertical through seams, and ensure the integrity of the module insulation layer.
2. Check whether the installation position and quantity of the connecting bridge meet the specifications, and make sure that the position standard of the module and the size of the wall section meet the requirements.
3. Check whether the grid size and wire diameter of the welded wire mesh meet the requirements, and whether it is installed in the slot of the connecting bridge end and whether the overlapping part and the corner part are firmly tied with binding wires.
Fourth, check whether the installation of L-shaped connecting bars meets the basic requirements of four per square meter. The construction of connecting bars is not less than 80cm deep into the structural wall, and should be evenly distributed. The tongue and groove guard can be protected with PCV pipe or pasted with ordinary tape.
5. Supervise the pouring process of concrete throughout the whole process. One point is to pour the outer protective layer first, and then pour the structural wall. When both inside and outside are self-compacting concrete, the height difference between inside and outside should not be greater than 50cm for alternate pouring.
6. The construction of sandwich core insulation is a systematic project, which cannot be completed independently by only one type of work, and requires the cooperation and cooperation of various types of work.
7. Reinforcement workers: It is necessary to perform vertical correction on the corner column, and ensure that the horizontal section of the corner column is at a right angle of 90°.
8. Woodworking: The EPS sandwich insulation module is not installed and the mold is not allowed to be closed without acceptance. When supporting the mold, attention should be paid to the protection of the insulation layer of the insulation module to reduce damage.
9. Shelf work: When setting up the outer frame, a horizontal rod should be added to place the shelf plate at 1/2 of the floor height, so that the insulation worker can install the module.
10. Concrete pouring workers: pay attention to the protection of the finished product and the order of pouring must be outside first and then inside.
