Ensure that the props are suitable for the intended purpose and can safely support the weight they will be subjected to. Overloading the props can lead to structural failure and collapse, posing a significant risk to workers. Furthermore, the props should be securely installed and adequately braced. This involves ensuring that the props are placed on a stable and level surface, with proper footplates to distribute the load. The props should also be securely tightened and locked in place to prevent any accidental movement or collapse. Regular inspections and maintenance of the steel props are also essential. This includes checking for any signs of wear and tear, such as loose bolts or damaged components, and addressing them promptly. Additionally, regular lubrication of the props' moving parts is necessary to ensure smooth and safe operation. When using steel props, it is essential to establish clear communication and coordination among workers. Adequate training should be provided to all personnel involved in the use of props, ensuring they understand the proper procedures and safety precautions. Clear signage and warning tapes should also be used to mark the area where the props are in use, preventing accidental collisions or tripping hazards. Lastly, it is crucial to follow all relevant safety regulations and guidelines when using steel props. Adhering to local, national, and international standards will help ensure that the props are used safely and correctly. By following these safety precautions when using steel props, the risk of accidents, injuries, and structural failures can be minimized, creating a safer working environment for all involved.

Q: Are steel props adjustable during construction?: Steel props are indeed adjustable during construction. They are often referred to as adjustable props or acrow props, and are frequently utilized in construction to provide support for temporary structures like formwork or scaffolding. The props are equipped with an inner tube that can be extended or retracted to attain the desired height. By twisting the threaded collar of the prop, the inner tube can be securely locked at the desired length, thus ensuring stability and support for the structure under construction. The adjustability of steel props makes it convenient for construction workers to easily accommodate various heights and levels throughout the construction process, establishing them as an indispensable and versatile tool in the industry.

Q: In the construction of the formwork support frame must be equipped with vertical and horizontal floor bar? Built in 26 meters of concrete surface, set up a height of 3.6 meters: According to the JGJ130-2011 (construction of steel tubular scaffold safety technical specifications), article 6.3.2 provides that the scaffolding must be equipped with vertical and horizontal sweeping rod. Vertical sweep rod should be fixed at right angles from the bottom of the steel pipe is not more than 200mm of the vertical pole. The transverse sweeping rod shall be fixed by a right angle fastener close to the vertical rod below the vertical sweeping rod.

Q: How do you maintain steel props?: To ensure the longevity and performance of steel props, it is important to follow a few essential steps: 1. Maintain cleanliness: After each use, particularly in harsh environments like construction sites, wipe the steel props with a clean cloth to remove dirt, dust, and debris. 2. Apply lubrication: Reduce friction, prevent rust, and ensure smooth operation by applying a thin layer of suitable lubricant, such as oil or grease, to the moving parts of the props. Avoid excessive application to prevent attracting more dirt. 3. Prevent rust: Regularly inspect the props for any signs of rust or corrosion. If detected, gently remove the rust using a wire brush or sandpaper. Afterward, apply a rust-proofing agent or paint to protect the exposed metal and prevent future rusting. 4. Proper storage: When not in use, store the steel props in a dry and well-ventilated area to prevent moisture buildup. To provide additional protection, consider covering the props with a waterproof tarp or plastic sheet. 5. Conduct inspections: Periodically inspect the props for wear, damage, or loose components. Check for cracks, bends, or excessive wear that can compromise the props' structural integrity. Promptly make repairs or replacements if any issues are detected to ensure safety and prevent further damage.
