Frame shear wall structure commercial residence landing Scaffolding Special construction scheme copy
"A famous garden" is located next to 207 National Road, Liuxie Community, Dongzhen Street, xx. It is invested and built by a real estate development limited company in xx, contracted by a construction engineering limited company, supervised by * supervision limited company, designed by * company, and geological drilling before design by * design institute. The project will be started in November 2014. The project is a commercial and residential building with a frame shear structure. There are 23 floors above the ground and 1 floor underground. The first floor underground is a garage and equipment room, the first floor is a shop, the second floor is a garage and the first floor of the residential lobby is a shop, and the 3-23 floors are residential buildings. The seismic fortification intensity is 7 degrees, The total construction area of the project is 34905.4118 square meters (including 31626.3677 square meters of ground construction area and 3279.0441 square meters of underground construction area), and the building height is 76.65 meters. The first floor is 6m high, the second floor is 5.2m high, the third floor is 3.3m high, the fourth to the twenty third floors are 3.1m high, and the roof framework is 5.5m high. The total height of the outer frame is 83.5m. The external scaffold shall be erected in combination (single pipe landing+pulling crane unloading). 2. The elevation of scaffold erection is+0.00m, and the maximum elevation of segmented scaffold is+83.5m. The erection form of single pipe landing+pulling and lifting unloading is adopted. Four pulling and lifting sections are set from+0.00m. Φ 14mm steel wire rope @ 1.50m and Φ 20mm rings are used for pulling and lifting unloading. Φ 48 × 2.8 steel pipes are actually used in the scaffold market. Considering the wear of steel pipes, Φ 48 × 2.8 steel pipes are used for accounting. The internal upright is 0.20m away from the wall; Pole step distance h=1.80m, pole longitudinal distance La=1.50m, pole transverse distance 0.80m; The transverse horizontal bar is at the bottom, and one longitudinal horizontal bar is arranged on the transverse horizontal bar; The wall connecting pieces are arranged in two steps and two spans (or set on the beam and slab according to the actual construction), and connected with two fasteners. The scaffold is fully paved with bamboo scaffold board. 3. Scaffold foundation: in addition to being supported on the top plate of the overhead floor, the rest are supported on the top plate of the basement or the backfill between the exterior wall of the basement and the coping beam, and the coping beam of the support pile. The foundation pit shall be backfilled with clay. During backfilling, it shall be leveled every 150 thick and compacted every 150 thick. The surface shall be poured with 15 thick C20 concrete. The slope shall be hardened by 0.5% to meet the requirements of bearing capacity. 10 # channel steel backing plate shall be set under it. A b × h=200 × 200 deep brick drainage ditch shall be set around the scaffold, and 350 × 300 grit chamber shall be set every 10 meters. No ponding and subsidence shall be allowed. The concrete of the roof must reach 75% of the design strength before construction. 4. The project meets the requirements of document (Scaffold) of Safety Management Measures for Divisional and Subdivisional Works with High Risks (JZ [2009] No. 87). The erection of floor type steel pipe scaffold with a height of 50m requires joint review by experts, The proposed landing scheme is listed as follows:+0.00 ～+23.80+23.80+23.80 ～+36.20+36.20 ～+48.60+48.60 ～+61.00+61.00 ～+83.50 Landing scaffold The first section of unloading scaffold The second section of unloading scaffold The third section of unloading scaffold The fourth section of unloading scaffold The falling section of unloading scaffold+0.00 ～+23.80 The seventh floor+23.800 ～+36.20 m The eleventh floor+36.20 ～+48.60 m The fifteenth floor+48.6 m 0~+61.00m 19th floor+61.00~+83.50m
