Crowned expo theme structure yesterday capped project is moving on as planned

Theme pavilions capped.

Yesterday morning, expo theme building construction site, a piece of steel beam two head hang red hibiscus, in "lifting" orders, crane steel lift slowly, placed in the top of the theme pavilions, marks the theme structure capped crowned. According to the plan, Qingdao expo theme pavilion is planning on July 26, 2013 complete curtain wall project, on September 5, 2013 complete installation engineering, September 30, 2013 complete fine decoration construction.

Ten months to complete capped progress

The main structure of the theme pavilions capped, marks the expo theme building engineering is scheduled in advance step by step. "We used ten months time, overtime, as long as at dawn, the project began, tower crane on the headlight, generally to do to the ten o 'clock at night." The garden and built by the general manager SunChongJu command before the large steel structure is introduced, "you see these steel frame, with more than 2400 tons of steel, each site is different, foundation treatment, complicated with type column and reinforced concrete beam node processing complicated shape, structure for the hyperboloid, positioning alignment is difficult, the welding technical requirement is high, so the progress of the projects is slow." He cited a example, theme pavilions high-rise building is not simply "stack of blocks", but unique made in order to make perfect workers to complete the task, every morning type, training and regular training has been on.

Electric heating to prevent steel local embrittlement

In the steel structure, a long list of wire along the steel structure laid, this is to give steel heating installation of local electric heating equipment, because the weather is cold, heating equipment to ensure that the steel to keep the temperature of the above 5 degrees below zero, to prevent the welding process of appear local embrittlement. "After the main structure capped, begin curtain wall, curtain wall has eight layer, and then is indoor warm water and electricity installation, indoor decoration." SunChongJu said that during the Spring Festival period, the site installation wall more than forty workers in fruit mountain the New Year, around the Spring Festival, theme building glass curtain wall to complete the workload of 20% to 30%.

Optical illumination fiber has hidden into the steel beam

Theme building engineering is one of the main venue expo, located in the area of flying area, with a total construction area of 28000 square meters, is divided into pavilion, multifunctional center, the competition hall and comprehensive service center four venues, the theme pavilions steel structure, the underground reinforced concrete, facade form for the double curtain wall and aluminum plate. The theme pavilion three layer, underground 1 layer, multifunctional center is the ground layer 4, underground 1 layer, flowers competition hall for the ground layer 2, underground 1 layer, comprehensive service center is 2 floors underground, the roof is planting roof, looking down from the mountain is four petals modelling, stereo sense is dye-in-the-wood. "Because the venue area is large, the day also want to have lighting, but the sun was shining in not enough light, light lighting with optical fiber is the light transfer to come in, inside the venue without Ann bulb, with a big glass bulb, optical fiber to replace the outdoor sun transfer to the glass in lighting, can save 30% of the electricity. Green building group field case ZhangDongPing said, optical fiber has been hidden into the steel structure. In addition, theme museum collection rain after processed water plants, flush the toilet, use clean energy to realize gas trigeneration, these facilities are in the main body in the steel structure to reserve the position.
