The guide rail is not less than 75cm above the ceiling. 2. Punch the holes for fixing expansion bolts of connectors on the wall column with a percussion drill. The spacing between connectors shall not be more than 600mm, and both ends shall be 100mm away from the guide rail opening. Fix several connecting pieces up and down first, stick the guide rail, correct its verticality and spot weld it, and then repeat the verticality of the guide rail after fixing the guide rail. The verticality of each meter shall not exceed 5mm, and the verticality of the whole length shall not exceed 20mm. The depth of the composite curtain embedded in the guide rail (see GBl4102-2005). 3. Install the rest of the connecting pieces. Spot welding shall be adopted between the connecting piece and the guide rail.
