Structural construction drawing of a sewage treatment station

Description This project is the third phase expansion project of the sewage treatment plant - complex building reconstruction project. This building is a reinforcement reconstruction project. That is, one floor is added on the top of the original old office building for office use. The drawings include: general description of structural design, reinforcement layout plan of frame column bottom, reinforcement layout plan of frame column top, reinforcement layout plan of frame beam, reinforcement layout plan of frame column top angle steel crossing floor, column reinforcement elevation and elevation of new columns on the second floor, reinforcement layout plan of newly added staircase without dismantling floor slab bottom There are 12 drawings in total, including the layout plan of newly added second floor column reinforcement, the layout plan of newly added second floor beam reinforcement, the layout plan of newly added second floor slab reinforcement, the layout plan of newly added staircase structure, and the detailed drawing of filling method of the original first floor roof back beam.

This project is a reinforced concrete frame structure for the gate and reception room of the sewage sludge treatment project of a river pollution comprehensive treatment project in Xianning City. The total building area is 48M2. The fire resistance rating of the building is Grade II. The reasonable service life of the building is 50 years. The roof waterproof grade of this project is Grade II. Environment class: Class 2a, foundation design class C, and crack control class III. Seismic fortification: the seismic fortification intensity is 6 degrees, the construction site is Class II, and the seismic fortification category of buildings is Class C. Seismic measures shall be taken according to 6 degrees. The fire resistance limit of the main structural members of the building is 3.0h for columns, 2.0h for beams, 1.5h for slabs, and 1.0h for non bearing walls.

Description Design elevation ± 0.00 is equivalent to the Yellow Sea elevation of 21.100m; The design safety level of the project is Level II, and the reasonable design service life is 50 years. Service environment category of concrete structure: Class IIa. The crack control level of structural members is Level III, and the maximum crack width limit is 0.2mm. The seismic fortification intensity of the construction site is 6 degrees, the design basic acceleration is 0.05g, and the design earthquake group is the first group. The construction site is classified as Class II. The buildings are all Class B buildings, and seismic measures shall be taken according to 7 degrees. The fire resistance limit of the main structural members of the building is 3.0h for columns, 2.0h for beams, 1.5h for slabs, and 1.0h for non bearing walls. Design load (standard value) dead load: dead load of waterproof and thermal insulation layer of dehydration workshop roof: 3.06KN/m2; Volume weight of slope making material: 6KN/m3. Dead load of waterproof and thermal insulation layer of sludge storage shed roof: 1.64KN/m2. Live load: non accessible roof: 0.5KN/m2.
