The seismic grade of this project is six degrees, and the structural safety grade is two, so it is seismic.
1. Structural engineering
The cushion of this project is C11, the foundation is manually dug pile, the concrete is C21, the foundation beam, column and beam slab are C25, and the floor is prestressed C31 hollow slab. Masonry works: the elevation below 1.111 is MU15 lime-sand brick, and the elevation above 1.111 is M11 cement mortar, and the first to fourth floors are MU11 lime-sand masonry works. More than four layers of MU11 lime-sand bricks, M5 mixed mortar, reinforced with steel bars; The roof is an integral cast-in-place slab, and the steel bars used in the reinforced concrete structure are Grade I and II steel bars; Welding and binding connection shall be preferred for steel bar connection.
2. Decoration project
The exterior wall of this project is made of exterior wall tiles and exterior wall coatings, while the interior wall, kitchen and bathroom tiles and others are painted with white latex paint with mixed mortar, the ceiling is painted with fangci paint with mixed mortar, the roof is made of APP modified asphalt waterproofing membrane, the downpipe is PVC151 anti-climbing downpipe, the doors are plastic steel doors, plywood doors and anti-theft iron gates, the windows are plastic steel windows, and the stair brick railings.
3. Installation project
(1) Water supply and drainage project
The water tank and tap water are planned to be used for water supply in the building, and the indoor water supply system of the building is divided into zones, and the water supply system adopts downward feeding type. The building is equipped with an indoor water inlet pipe and an outdoor pipeline connected in a ring shape. Portable fire extinguishers shall be arranged in the floor aisles and corresponding positions.
the indoor domestic water supply pipe adopts PVC-U polyvinyl chloride water supply pipe and fittings.
PVC-U rigid PVC drainage pipes and fittings are used for indoor sewage pipes and rainwater pipes, which are socket-bonded.
the top soil of domestic water supply pipe is 1.75m; The support and hanger of PVC-U water supply and drainage pipe shall be constructed in strict accordance with the specification requirements, and pipe clamps shall be added to the stressed parts such as taps and valves to strengthen the stress strength.
(2) lighting project
the power supply incoming line of this project adopts YJV22-1KV power cable directly buried, with a voltage of 381/221 volts and a three-phase four-wire system.
