Abstract
According: to building design specifications and other relevant standards and design requirements and provide geological data, the design of the framework of the classroom building. After the first building in accordance with the structure and layout of the overall after the first local node design steps design. Main contents include : design, architectural design of the total shows that the construction of the plane, Facade, profile design specifications, , and other parts of the design; structural layout and schematic calculation of identification, load, stress, the combination of internal forces, Main beam reinforcement design and calculation, frame-section design and reinforcement, meeting beam reinforcement design, floor and roof design, stair design, infrastructure design. Enclosing wind load under the framework moment, shear and axial bid; vertical and horizontal seismic loads under the framework of the moment, shear and axial bid; Constant load and live load under the framework moment, shear and axial trying to internal forces and the combination of beam-column table.
Key Words:frame, Gravity load charecter value , cast-in-place reinforced concrete structure , internal force make up , curved square amplitude modulation.
本设计教学楼位于郑州市,用地755方米,红线范围为50m×20m。该地段地势平坦,环境较好,在选址和环境营造方面,注意自然景色的优美,也重学习环境各交通条件的因素,更强调人与自然环境的协调统一,比较适合教学楼功能的充分利用。
根据设计资料的规划要求,本教学楼建筑要求的主要功能有:门卫室,教师休息室,大教室,小教室,多媒体教室等。
设计标高:室内外高差:450mm。
墙身做法:墙身采用250厚的加气混凝土块。内粉刷为混合沙浆浆底,纸筋抹灰面,厚20mm, 内墙涮两度涂料,外墙贴砖。
楼面做法:楼面(大理石楼面),100厚现浇钢筋砼楼板,20厚板底抹灰。
屋面做法(上人屋面):见建筑设计部分。
