Description

Technical Field

[0001] The invention relates to the technical field of building structures, and in particular to a roof structure for assembled houses. Background Art

[0002] Wooden cubic prefabricated houses, especially low-rise prefabricated houses, are widely used in low-rise villas, prefabricated customized houses, tourist resorts or camp hotels due to their advantages such as fast construction, fast construction speed, good adaptability to the ground environment, high safety, and reusability. Prefabricated houses generally build a steel structure frame first, and then install the ground, wall, floor, roof and other structures. Traditional prefabricated houses have the following main disadvantages when they are built. First, when the roof is installed, welding or direct screw fixing is generally used at each docking position. The welding method is complicated to operate, requires professional welding personnel, and is troublesome to disassemble, while the structural stability of the direct screw fixing method is not high enough; second, the accessories are not very versatile and cannot be used as standard parts, which makes the construction and installation process more troublesome.

[0006] Furthermore, for situations with larger spans, one ring beam may not be long enough, and at least two ring beams need to be butted together. At this time, the butt joint position in the middle of the ring beam is connected and fixed to the middle column through a ring beam butt joint connector. The ring beam butt joint connector has a main kit, and a fixing ear is provided on each side of the bottom end of the main kit.
