1, after the ground or ground brick is laid 7 days, the mortar strength reached a certain degree before the railings can be installed.
When drilling the floor brick with a drilling rig, the size of the hole should be within the range of stainless steel railings and buckles, and the floor brick should be protected. If the floor brick is damaged, the railings construction unit shall bear all economic losses on its own.
3, welding the column in the expansion bolt must be welded firmly, before welding to arrange the position of the column. After the column is welded firmly, the stainless steel buckle cover is buckled in time, and then the lower part is welded and then the handrail is welded. The gap between the handrail and the column is not greater than 0.3 mm. After all the horizontal bracing is welded, the tube should be welded at the same distance to achieve a beautiful effect. The columns, handrails, and tubes should be welded on both sides. In order to prevent weld deformation, welding should be done first and then fully welded. The welds should be uniform, beautiful and neat, the angle after the handrail welding should be the same as the angle of the stairs. After the railings are welded on both sides, they should be processed separately according to the actual size. After the welds, the angles should be smooth and the gaps should be uniform.
After welding the stainless steel railings, the weld should be polished and polished in a timely manner. After polishing, the brightness of the weld should be the same as other places. There should be no obvious traces after grinding the handrail joints.
5, stainless steel railings column, armrest of the buckle cover application glue with the ground, wall adhesion, should not be active.
6, construction should be in accordance with the actual situation of the site plate test press, and do the sample room, until the inspection and approval of Party A, before the construction of a large area.
7, after the protective fence plate is installed, the side thrust must not be less than 80 kilograms, and the handrail has no sense of shaking.
After the installation of stainless steel railings, they shall be qualified after inspection, acceptance and approval by the personnel of the company's project department.
