Large-angle double-layer cornice roof special-shaped steel structure and construction method
The invention discloses a large-angle double-layer cornice roof special-shaped steel structure and a construction method.The large-angle double-layer cornice roof special-shaped steel structure comprises an inner arc truss and an outer arc truss, and the outer arc truss is arranged on the outer side of the inner arc truss; each of the inner arc truss and the outer arc truss is obtained by manually lofting and welding a plurality of units according to a pre-assembly lofting graph of the inner arc truss and the outer arc truss, and the inner arc truss and the outer arc truss are supported by a jig frame on the ground during pre-assembly; lower chord beams are arranged on the two sides of the inner arc truss and the two sides of the outer arc truss, each lower chord beam is composed of a plurality of box beam units, the inner arc truss and the outer arc truss are further provided with stand column units, and each stand column unit is composed of a plurality of stand columns and box beams. The construction method is suitable for the large-angle double-layer cornice roof special-shaped steel structure. The large-angle double-layer cornice roof structure can replace a cornice roof structure of a concrete structure and is used on a large-angle double-layer cornice roof with the gradient being 40 degrees or above, building of the large-angle double-layer cornice roof is achieved, and building is safer.
本发明公开了一种大角度双层飞檐屋面异形钢结构及建造方法，其中，大角度双层飞檐屋面异形钢结构包括内弧桁架和外弧桁架，外弧桁架设置在内弧桁架的外侧；内弧桁架和外弧桁架均由多个单元按照内弧桁架和外弧桁架的预拼装放样图进行人工放样并焊接得来，内弧桁架和外弧桁架在预拼装时均通过地面的胎架进行支撑；内弧桁架和外弧桁架的两侧均设有下弦梁，下弦梁由多个箱型梁单元组成，内弧桁架和外弧桁架还设有立柱单元，立柱单元由多个立柱和箱型梁组成。本发明的建造方法适用于上述大角度双层飞檐屋面异形钢结构。本发明能替代混凝土结构的飞檐屋面结构，使用在40°以上坡度的大角度双层飞檐屋面上，实现大角度双层飞檐屋面的建造，建造更加安全。
