Stainless steel railing

Construction technology of stainless steel railing

1, engineering process:

Installation of embedded parts → Pay-off → Installation of columns → Connection between handrails and columns → Grinding and polishing.

2, install embedded parts:

The installation of railing embedded parts can only be done by adding embedded parts after installation. The method is to use expansion bolts and steel plates as rear joints. Firstly, the position of the fixed point of the column is determined by setting out on the basis of civil engineering, then the hole is drilled on the ground with an impact drill, and then the expansion bolt is installed. After the bolt is positioned, tighten the bolt and weld the nut and screw to prevent the nut and steel plate from loosening. The connection between the handrail and the wall also adopts the above method.

Step 3 pay off

Due to the above-mentioned rear built-in structure, errors may occur. Therefore, before the installation of the column, pay-off should be carried out again to determine the position of the buried plate and the accuracy of the welding stud. If there is any deviation, correct it in time. Ensure that all stainless steel columns are located on the steel plate and can be welded around.

4, install the column

Two people are needed to weld the column. Hold the steel pipe vertically by one person, and do not shake it when welding. Welding of the other side and all around shall conform to the welding specifications.

5. Connection between handrails and columns

Before installation, pay off the line by drawing a long line, and process a groove at its upper end according to the inclination angle of the site and the roundness of the handrails used. Then put the handrail directly into the groove of the column and install it by spot welding from one end to the other. Adjacent handrails are installed and butted accurately, and the joints are tight. After the adjacent steel pipes are butted, they shall be welded with stainless steel covered electrode. Before welding, oil stains, burrs and rust spots within the range of 30 ~ 50 mm on both sides of the weld must be removed.

6. Grinding and polishing

After all welding is completed, use a portable grinder to grind the weld until the weld is not visible. When polishing, use flannel grinding wheel or felt for polishing, and use corresponding polishing paste at the same time, until it is basically consistent with the adjacent parent material, and no weld appears.

Matters needing attention in the construction of stainless steel railings

In the installation of stainless steel railings, the construction technology of stainless steel railings is very important. In general, the distance between parallel lines and sections is not allowed to exceed 0.5mm..

The diagonal error of zinc-steel railings of the same specification should not exceed 1mm, which requires that the technical level of stainless steel railings in construction is very high, so as to ensure the beauty and firmness of stainless steel railings after installation. After the safety installation is completed, the owner and supervision department need to check and accept it.
