Technical Field

[0001] The utility model relates to the technical field of roof installation components, in particular to a metal roof sliding support connection node fixed on one side. Background Art

[0002] Metal roofs are mainly used in large-scale, large-span public buildings such as airports, exhibition halls, stadiums, and the main roofing form of industrial buildings. Metal roof panels are generally arranged longitudinally in the drainage direction. The length of the roof panels of large roofs is generally 20 to 50 meters, and some large public buildings even have roof panels that are more than 100 meters long. Due to the large temperature difference in the use environment of metal roofs, the roof panels need to be able to expand and contract freely in the length direction under the action of thermal expansion and contraction to ensure the release of temperature stress of the roof panels. Therefore, the connection and expansion and contraction of the roof panels and the roof supports are key technologies and specification requirements for roof waterproofing and wind resistance. Existing metal roofing systems usually use upright interlocking fixed supports and rolled sliding vane supports, which have weak wind resistance and poor expansion and contraction performance. Wind damage to large metal roofs poses great safety hazards and economic losses.
