Installation of pre-buried parts → line placement → installation of stainless steel railing column → connection stainless steel railing column → polishing
2、Installation of pre-buried parts:
The installation of the railing pre-buried parts can only be used after adding the buried parts practice, the practice is to use expansion bolts and steel plates to make the post-connector, first put lines on the grass-roots level of civil construction, to determine the location of the stainless steel railing column fixed points, and then on the ground with impact drilling, and then install expansion bolts, bolts to maintain sufficient length, after the positioning of the bolts, the bolts will be tightened at the same time between the nut and screw welded to prevent the nut and steel plate Loose. Handrail and wall surface connection also take the same method.
Due to the above-mentioned post-embedded construction, there may be errors, therefore, before the installation of stainless steel railing column, should be re-placed to determine the location of the buried plate and the accuracy of the welded rod, such as deviation, timely correction. Should ensure that all stainless steel stainless steel railing column is located on the steel plate, and around can be welded.
4、Installation of stainless steel railing column
Welding stainless steel railing column, need two people, one holding the steel pipe to keep it vertical, in welding can not shake, the other person welding, to weld around, and should comply with the welding specifications.
5, handrail and stainless steel railing column connection
Stainless steel railing column before installation, by drawing a long line to put, according to the angle of inclination of the site and the roundness of the handrail used, the groove is processed at its upper end. Then the handrail directly into the stainless steel railing column groove, from one end to the other end in order to spot welding installation, adjacent handrail installation docking accurate, tight seams. After the adjacent steel pipe butt, the seam will be welded with stainless steel welding rod. Before welding, the oil, burrs, rust spots, etc. along the weld must be removed within 30-50mm on each side.
6、Sanding and polishing
After all the welding, with a portable sander will be welded flat sanding, until not show weld. Polishing with a flannel wheel or felt polishing, while using the appropriate polishing paste, until the basic consistency with the adjacent base material, no weld.
Stainless steel railing column construction precautions
In the stainless steel railing column installation, railing column construction process is very important, in general the parallel line distance and segmentation distance is not allowed to exceed 0.5 mm.
The same specification of zinc steel railing diagonal error is not more than 1 mm, so that the stainless steel railing column in the construction of the level of technology is very high, in order to ensure that the stainless steel railing column after the installation of the beauty and sturdiness, in the safety of the end of the installation, the need for the owner and the supervision of the inspection and acceptance of the department.
