Background technique

Purlin structures are commonly used load-bearing building components in existing buildings. Various steel beams are often used, such as I-beams, rectangular tubes and other materials. When the span is small, the structure can well withstand the pressure of the building floor. However, when the span increases, the traditional purlin structure cannot be installed to connect heavy equipment suspension components such as wind, water, electricity, and horse tracks due to insufficient force. For this technical problem, the existing solutions have a technical bias that can only be solved by means of perforated welding and adding fixing parts to strengthen the bearing capacity of the purlins and the building floor. However, the above treatment methods usually carry out destructive treatment to the building floor, which affects the service life of the building floor. Welding support parts, because the welding process needs to consume energy, and there is an open flame, it will bring certain safety risks to the construction. At the same time, in other known suspension components, when the contact area of the building floor is relatively small or the number of suspension points is too small, when the suspension load increases, the problem of insufficient stress of the suspension components will occur.
