Climbing frame, climbing frame mesh should be maintained, or it will be corroded and rusted
Climbing grid should pay attention to maintenance or it will rust! Climbing scaffold mesh in the engineering personnel in the process of long-term use, can make all kinds of stains remaining in the mesh, coupled with the influence of natural factors (such as rain and snow, the temperature rise and fall, etc.), will make the stain penetration to climb step by step the internal structure of the mesh, eventually leading to the surface in some parts of the iron mold, and this also happens to be the most deadly, when iron mold saturation on the surface of the product, means that climb the oxide layer of mesh have failed and gradually turn into all corrosion rust, finally break the condition of deformation. Fortunately, this situation is found earlier, if the use of this state for a few months, the network will be damaged.
Climbing frame refers to the outer scaffold with anti-overturning and anti-falling device, which is built by the climbing frame manufacturer to a certain height and attached to the engineering structure. Depending on its own lifting equipment and devices, it can climb or fall layer by layer with the engineering structure. The attached lifting scaffold is mainly composed of attached lifting scaffold structure, attached support, anti-tilt device, anti-fall device, lifting mechanism and control device.
Next, we will explain the six points for the use of the crawler mesh products.
1. When the welding parts of the product itself are seriously deformed, the degree of damage shall be done or repaired or replaced.
2. The construction of guide rail, support structure, horizontal girder pole and main frame of the crawler mesh is seriously bent. Please do not use it again.
3. The crawler grid that does not meet the design requirements shall not be applied in the construction project, because it does not conform to the normal design concept, which will easily cause the occurrence of safety accidents.
4. When the anchor parts of the product are deformed and worn, they should be replaced or repaired in time; otherwise, they should not be used, because these anchor parts will affect the tightness of the product.
5. If the spring part used for stretching mesh is invalid, it should be replaced in time.
6. If the steel wire rope parts are in a state of knots, twist, wear and break, etc. and seriously reach the state of being scrapped as stipulated by the state, the application of the steel wire rope mesh shall be stopped and the steel wire rope shall be replaced or repaired. Climbing grid must pay attention to maintenance or it will rust!!!
The material of stainless steel is Cr alloy steel. In stainless steel, chromium is more active than iron. First, it is oxidized with the environment to form a compact oxide layer (called passivating film) that is firmly combined with the steel matrix. The higher the content of chromium, the better the corrosion resistance of steel. Nickel (Ni), manganese (Mn), milling (Ti), silicon (Si) and other elements should be added to improve the performance of stainless steel.
According to the different chemical composition, stainless steel can be divided into chromium stainless steel, chromium nickel stainless sodium and high manganese low chromium stainless steel. According to the characteristics of corrosion resistance, it can be divided into ordinary stainless steel (stainless steel for short) and acid-resistant steel. Ordinary stainless steel has the ability of resisting air and water vapor erosion. Acid-resistant steel not only has the ability to resist corrosion of atmosphere and water vapor, but also has good corrosion resistance to some chemical erosion media (such as acid, alkali and salt solution). There are over 40 kinds of stainless steel commonly used.
Stainless steel is not only resistant to corrosion, but also has a metallic luster. Stainless steel after different surface processing, can form different glossiness, and divide different grade according to this. Advanced polishing non - rust fishing has mirror - glass - like reflection.
