The height of mezzanine generally does not exceed 2.5m, so it can be excluded from the number of floors of commercial buildings. People who don't know it are generally called "attic", which is generally a sloping roof with mezzanine.
Building structure plan, general description of the structure, foundation layout, bearing platform reinforcement plan, ground beam layout, floor column layout, floor column reinforcement plan, roof beam reinforcement plan, stair roof beam reinforcement plan, floor slab reinforcement plan, roof slab reinforcement plan, stair detail plan and node detail plan.
Extended data:
General building structure plan, should have the floor structure plan and roof structure plan, drawing the specific content is:
(1) Draw the position and necessary positioning dimensions of the positioning axis, beams, columns, load-bearing walls and seismic structural columns, and indicate their numbers and floor structural elevations.
(2) When using precast slab, the span direction, slab number, quantity and slab bottom elevation of precast slab shall be indicated, and the size and position of reserved holes shall be indicated; Location and model of precast beam and portal lintel, and elevation of beam bottom.
(3) The cast-in-place slab shall be marked with the slab thickness, slab elevation and reinforcement (an enlarged reinforcement diagram can also be drawn separately. When necessary, the template diagram and reinforcement diagram of the cast-in-place floor slab shall be drawn separately. Local section drawings shall be drawn where the elevation or thickness changes. When there are reserved holes, embedded parts and built equipment foundations, the specifications and positions shall be indicated, and reinforcement measures shall be taken at the edges of holes. When reserved holes, embedded parts and equipment foundation are complicated, detailed drawings can also be drawn separately.
