Description :

　　platform beam

　　Platform beams are generally made of solid web members with equal cross-sections (welded H-beams or hot-rolled steel sections, etc.). When the span and load are large and a high torsional stiffness is required, box section beams can also be used; When the span is large but the load is small, truss beams can be used. The cross-sectional height of a beam is determined by factors such as allowable deflection, economic height of the beam, and building clearance requirements. The spacing a between secondary beams is determined based on the strength and stiffness of the pavement, generally between 600-1000mm.

　　Steel platform safety maintenance

　　1. Steel platforms should be equipped with load limit signs.

　　2. The placement point and upper connection point of the steel platform must be located on the building and must not be set on construction facilities such as scaffolding. The support system must not be connected to the scaffolding.

　　3. The concrete beams and slabs at the steel platform placement point should be embedded and connected to the platform's bolts.

　　4. The horizontal angle between the steel wire rope and the platform should be between 45 degrees and 60 degrees.

　　5. The tensile strength of the beams and columns at the upper tension points of the steel platform should be calculated to ensure the safety of the building and the platform.

　　6. When using a steel platform, a snap ring should be used and the lifting hook should not be directly hooked onto the platform lifting ring.

　　7. When installing the steel platform, the steel wire rope should be hung firmly with hooks, and when using other methods, there should be no less than 3 buckles. Soft cushions should be added to the steel wire rope around the sharp corners of the building, and the outer opening of the steel platform should be slightly higher than the inner side.

　　8. Fixed guardrails and dense safety nets must be installed on both sides of the steel platform.

　　Steel structure platform, also known as work platform. Modern steel platform structures come in various forms and functions. Its large structure is characterized by a fully assembled structure, flexible design, and is widely used in modern storage.

　　Engineering structures made of steel, typically consisting of beams, columns, slabs, and other components made of steel sections and plates; The various parts are connected by welds, screws, rivets, etc.

　　The platform design of lightweight steel structures mainly involves the design of beams, columns, and platform plates, and their calculations are mainly done through manual calculation or compilation In lightweight platform structures, the connection between the platform deck and secondary beams or other components is usually made using intermittent welds, and the net distance should not exceed 15t when the deck is included in the calculation section of the beam or stiffeners, and should not exceed 30t in other cases (where t is the thickness of the thinner weldment).
