Steel pipe frame
Steel pipes also need shelves in the process of production. The shelves of steel pipes are different from other shelves. In this way, the production of steel pipes will be better and the benefits will be better. How is the shelf of steel pipe set up? The following is a small series to introduce you in detail, welcome to pay attention to:
First, set up the scheme
This project is a 20 - storey commodity residential building. The top elevation of the large roof is 58.0m, and the top elevation of the small roof such as the roof room is 62.8m. The construction arrangement of the outer frame is: double row steel pipe landing frame to the top of 3 layers, 4 layers (8.70m), above the use of I-beam pick frame to pick three steps inverted roof. The elevations are 8.7m, 26.1m and 43.5m respectively, and six floors are selected to the roof respectively. Outside the room of the roof, the lifting frame is used to reach the top, and inside, the steel pipe landing frame is built on the roof: (9 plane layout of the lifting frame for each room with elevations of each lifting layer). Materials: The horizontal rod is made of No. 16 I-beam steel, and a small amount of the rod with stayed pull is made of 6×19,1400 grade, 31 steel wire rope. The project is located in Xuzhou, Jiangsu province. The basic wind pressure is 0.350kn/m2, the wind load height variation coefficient uz is 1.86, and the wind load body type coefficient us is 1.134:;
The wind load is considered in the calculation.
4. Static load parameters
Standard value of structural dead weight load per meter vertical pole (kn/m) : 1.1278;
Standard weight of foot and hand plate (kn/m2) : 0.150; Standard value of dead weight of balustrade footboard (kn/m) : 0.150; Safety facilities and safety net self-weight standard value (kn/m2) : 0.005:; Foot board laying layer: 9 layer foot board category: bamboo and basketry foot board; Railing baffle category: railing, bamboo wattle piece foot handboard baffle;
5. Horizontal cantilever support beam
The cantilevering horizontal steel beam is made of No. 16 steel, in which the length of the external suspension section of the building is 1.5m, and the length of the anchoring section inside the building is more than 2.0m.
Diameter of bolts connected with the floor plate (mm); 2m20; Or 2 Phi 16 bar
Floor concrete label: c30
