Extra-large-span light steel roof truss and mounting method thereof
The invention provides an extra-large span light steel roof truss and a mounting method thereof. The extra-large span light steel roof truss comprises lower chords, vertical web members, diagonal webmembers, horizontal members and upper chords, the vertical web members and the diagonal web members are arranged on the lower chords, the vertical web members and the diagonal web members are arrangedin at least two layers, and the horizontal members are arranged between the vertical web members and the diagonal web members; wherein the upper chord member is arranged at the topmost parts of the vertical web members and the inclined web members, a roof truss is formed by the lower chord member, the vertical web members, the inclined web members, the horizontal members and the upper chord member, the lower chord member is arc-shaped and arches upwards, the lower chord member is square steel, and the upper chord member is H-shaped steel and is formed by welding steel plates. By using the light steel material and the multi-layer composite structure, the problem of 75m span is solved, the blank of a steel roof truss structure is filled, the cost is saved, the manufacturing cost is reduced,and the problems that a steel structure with a large span cannot be implemented and the dead weight is too large are solved.
本发明提供一种特大跨轻钢屋架及其安装方法，包括下弦杆、竖腹杆、斜腹杆、水平杆和上弦杆，所述竖腹杆和斜腹杆设置在下弦杆上，所述竖腹杆和斜腹杆至少为两层，且水平杆设置在竖腹杆和斜腹杆之间，所述上弦杆设置在竖腹杆和斜腹杆的最顶部，通过下弦杆、竖腹杆、斜腹杆、水平杆和上弦杆组成屋架，所述下弦杆为弧形且向上拱起，所述下弦杆为口型钢，上弦杆为H型钢，且均由钢板焊接成型。通过使用轻型钢质材料，并且通过多层次复合结构，解决75m的跨度难题，填补钢质屋架结构上的空白，并且节约成本，降低造价，解决了跨度较大的钢结构无法实施且自重过大的问题。
