The fasteners used to secure the rails on which the elevators work on the wall are called elevator guide brackets, which are used to secure the elevator rails with bolts and clips.
By mounting the elevator brackets on the walls of the elevator shaft, the loads imposed by the elevator are transferred to the structural support system of the building.
In summary, the guarantee of the proper functioning of the elevator depends on the quality of these elevator fixings. also most certain elevator bracket. Certain errors in the design and manufacture of elevator rail guide fasteners used on the market;
Disadvantages of the welded joint
To remedy manufacturing defects, it is necessary to deteriorate the integrity of materials and waste time. Many variables determine the resistance of the welding process and its forces.
These are mainly;
Moisture, clean surfaces, finish quality, adequacy, and stability of electrical current, contact surface width, electrode quality, welding material compatibility
Site conditions (height, work area, etc.)
Many welding methods are based on fusion and cause internal stresses and deformations. After melting, the solder materials that solidify become brittle. After cracking, the materials break after exceeding the yield stress and show almost no creep.
Not all materials are suitable for welding. Some materials may retain solder for a moment. Welding by someone who does not know the materials can have irreversible results. Even in the case of welded notched welds, homogeneity of the weld can not be guaranteed, especially in the manufacture of elevator rail brackets.
Fluctuations in the size of materials due to changes in air and temperature can cause cracks and weld breaks. In the event of an earthquake, welded joints, especially in the corners, will exhibit a brittle behavior of the materials and could cause sudden breaks in the event of an impact.
