■ The Leiting Heavy Project - metallurgical automatic transmission equipment assembly base steel structure project. Located in Qingdao High-tech Zone, the span is 120 meters, total length is 198.1 meters; eave height is 13.2 meters; the ridge height is 18.6 meters.
■ The workshop steel column is lattice without anchor bolt that has a strict requirement for the steel column¡¯s perpendicularity, elevation and axis deviation. The column bracing, welded by channel steel and angel steel, is double layer installation. Roof horizontal bracing is continuous connection by angel steel; the middle column crane beam is divided into two layers. All crane beams are installed walkway plate and guardrail and each walkway plate has two ladders and escalators. The wall panel use v-780 type wave board; the wall between the upper and the lower window is the horizontal installation, the upper window is skylight plate, therefore the wall installation must be vertical to avoid clearance.
