A building in Beijing is light Steel keel Partition construction scheme
? The total area of light steel keel gypsum board partition in this project is 66800m2, and the east and west towers are symmetrically distributed. Gypsum board walls are mainly distributed in offices, corridors, toilets, stairwells, elevator vestibules, tube wells, fan rooms, and intelligent system rooms? The project mainly adopts C-type keel gypsum board partition system, CH type keel gypsum board partition system and cladding keel gypsum board partition system? Type C keel is used for ordinary gypsum board non bearing internal partition wall, which has the characteristics of light deadweight, good fire and sound insulation effects, convenient construction, and dry operation replacing traditional wet operation? CH type keel is used for fire protection system of tube well wall, such as staircase, elevator shaft and ventilation shaft. With efficient fire and sound insulation performance, good strength, stiffness and impact resistance? The overlaid veneer wall system can effectively correct the unevenness of the wall, and has good moisture-proof and thermal insulation properties? The fan room on the 3F-30F floor of the main building adopts a curved gypsum board partition system. The corner keel is used as the heaven and earth keel, which is cut every 5cm. The vertical keel spacing is 500mm. The paper faced gypsum board should be horizontally jointed along the length direction? The gypsum board partition of the ground toilet must be poured with 200mm high plain concrete guide wall on the structural floor slab, with the wall thickness of 111mm; The cable bridge wall of the strong and weak current room is poured with 150mm high plain concrete guide wall on the structural floor slab, with the wall thickness of 124mm; The pipe well partition must be poured with 150mm high plain concrete guide wall on the structural floor slab, the wall thickness is 99mm, the concrete strength grade is C20, and light steel keel partition wall shall be installed on the guide wall? The concrete is easy to be broken due to the use of shooting nails to fix the ground keel at the edge of the tube well and the plain concrete guide wall. If the ceiling keel is broken when it is fixed with a nail, a hand electric drill can be used to drill holes on the structural floor slab at 400mm interval in the tube well and toilet, a nail hammer can be used to drive the plastic expansion bolt into the hole, and the ceiling keel is fixed in the plastic expansion bolt with a screw at 400mm interval.
