AI Technical Summary
Technical Problem
Existing large-span roof structures are difficult to construct, have long construction periods, poor stability, and cause serious waste of resources and environmental pollution after demolition.
Method used
It uses curved wooden beams and glued laminated timber beams connected by round steel pipes. The splicing structure and butt joints achieve a fast and stable connection. The main material is wood, which is prefabricated in the factory and assembled by mechanized on site.
Benefits of technology
It achieves a large-span roof structure with good stability and strong load-bearing capacity, with a short construction period, environmental protection and recyclability, avoiding resource waste and environmental pollution.

Abstract
This invention discloses a large-span roof structure, including curved timber beams, both ends of which are fixed to a concrete foundation. Each curved timber beam comprises multiple sequentially spliced curved timbers, with a splicing structure between adjacent curved timbers. A glued laminated timber beam comprises multiple sequentially butted glued laminated timbers, with adjacent glued laminated timbers connected by a butt joint. The butt joint includes a butt plate, with a first insert on one side and a second insert on the other. Adjacent glued laminated timbers are respectively provided with slots that mate with the first and second inserts. The large-span roof structure of this invention is stable and reliable, with strong load-bearing capacity and high stability. The curved timbers and glued laminated timbers can be prefabricated in a factory and assembled mechanically on-site, reducing the construction period and improving construction efficiency and installation accuracy. The splicing structure between adjacent curved timbers allows for a convenient, quick, stable, and reliable connection between them.
