Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a ring-roof metal roof structure. Background Technology

[0002] Steel truss roof structures are widely used in industrial plants, stadiums, exhibition halls, and other large buildings, as well as commercial buildings, due to their fast construction speed, high material utilization, and design flexibility, meeting the architectural needs of different functions and aesthetic requirements. A traditional steel truss roof structure typically consists of the following main components: a rigid truss, composed of several members (such as main trusses and secondary trusses) forming a geometric frame that primarily bears vertical and wind loads; roof panels, serving as the main roof covering layer, bearing other loads on the roof (such as equipment, insulation layers, etc.); an insulation layer, improving the roof's thermal insulation performance and reducing energy consumption; a waterproof layer, preventing rainwater penetration and protecting the internal structure; and a finishing layer, providing an aesthetically pleasing appearance while also protecting the internal structure. While steel truss roof structures offer many advantages, they also have some drawbacks and potential problems: 1. Complex construction: Installation and connection nodes require high precision, making the construction process complex; 2. Risk of leakage: Construction defects are easily found at the joints between the roof panels and the waterproof layer. Incomplete waterproofing can lead to rainwater leakage, affecting the indoor environment. 3. Due to the large indoor space, improper construction of the insulation or heat insulation layers can easily lead to heat loss or heat accumulation, affecting indoor comfort and energy efficiency. 4. The roof structure is quite sensitive to external noise transmission; in noisy environments, indoor noise levels can be high, impacting comfort. Therefore, these drawbacks need to be fully considered during the design and construction phases to ensure the long-term stability and safety of the steel space frame roof structure.
