Steel grating installation and construction quality defects and prevention measures
Steel grating installed tendons are not aligned
Preventive measures: the same position grating installation should try to use the same batch of product, pre-installation review the size, size does not comply with the small size of the local, steel grating fixed before the first draw a good line, adjust the alignment after welding.
Steel grating openings are not Edge
Pipeline through the platform steel grating edge treatment or failed to take edge treatment unsightly, deformed steel grating hole after hole center and the center of the pipe (running) is inconsistent, obviously skewed.
Preventive measures: pipes through the platform steel grating steel grating openings should be drawn according to the pre-opening position of the center of the center of the pipe, pipe diameter, pipe expansion displacement after cutting with a cutter along the painted line position, the timely closure after cutting edges. After sealing the pipe before installing Office.
Cutting unprotected
Precautions: platform steel grating plate welding, cutting operations must be laid beneath the iron, galvanized steel grating to prevent damage layer.
Failure to require cutting steel grating
Pipeline construction steel grid plate flame cutting irregular, affecting appearance.
Precautions: When installing pipes need to wear steel grating, the first based on the location of the center of the pipe, the outer diameter of the pipe set cutting position and crossed. Maximize the use of cutting machine, if the flame cutting, grinding wear tube should be promptly after construction clean.
Unprotected
Wire rope lifting equipment directly through
steel grating, steel grating causing damage.
Preventive measures: suspension points if equipment lifting steel grating, protective measures must be taken, if necessary, a temporary removal of the steel grating, lifting completed and then resume the installation.
Steel grating overload damage
Precautions: When stacking materials and equipment on the platform beneath the pad must be flat with square wooden, stacked items can exceed the design load, when the scaffolding set up on the platform, the lower pole must pad tablet protection.
