Increase steam pressure and gas filling concrete Construction quality of blocks
Project name: Zhejiang Film and Television Post production Center Phase I Film and Television Post production Complex Building Project Building area Total building area: 190243 square meters; The aboveground building area is 142830 square meters, and the underground building area is 47413 square meters Building scale and height The height of the main building (42F) is 218m, and the height of the podium building (5F) is 30m The main structure is frame core tube structure; Frame shear wall structure of podium in studio area; Frame structure of the podium on the north side of the main building The number of floors is 2 floors underground, and the above ground part is composed of a 5-storey podium and a 42 storey tower. The quality requirements ensure the "Qianjiang Cup" and strive for the "Luban Prize". The volume of wall masonry is about 19000 ㎡. 200 thick autoclaved sand aerated concrete block walls are used for some exterior walls above ± 0.00 elevation, 200 or 100 thick autoclaved sand aerated concrete block walls are used for interior walls, and 200 thick autoclaved sand aerated concrete block walls are used for firewalls. The fire resistance limit is more than 3 hours, and special adhesives are used for masonry. Considering the influence of the quality of autoclaved aerated concrete block masonry on the later wall plastering, the Project Department requires strict control of the construction quality of aerated concrete blocks to ensure the smooth progress of later plastering. However, in the process of aerated block masonry, it is easy to see the deviation of the flatness and perpendicularity of the masonry, the uneven mortar leakage during the pouring of the ring beam structural column, and the weak quality awareness of workers.
