1. Before the installation of pvc guardrails, civil engineering has usually formed a lower foundation for delivery of brickwork or concrete pouring. The guardrail can use mechanical expansion bolts, chemical screw inspection, etc. to fix the column steel substrate board at the center of the lower foundation for straight line. cloth.
2. If the lower foundation of the wall has not been formed, it is recommended to directly embed the length of the column steel lining in the wall body, and it can be formally constructed after the wall maintenance period; or after the prefabricated embedded parts are laid on the wall plane, the column steel The lining is welded to the embedded parts by electric welding. These two methods are characterized by being stronger than the bolt connection, but the straight line and the horizontal line must be paid attention to when presetting.
3. The spacing of the column steel lining must be consistent with the design size to ensure that the pre-assembled semi-finished products can be connected to it.
4. Pull two parallel lines of upper and lower limits at the entire distance of the straight line as the installation adjustment reference. Ensure the straightness of the upper and lower ends after the installation of the guardrail is completed.
