Study On Design Of Prefabricated Concrete Stereoscopic Garage

In the twenty-first century, China’s economic development rapidly, and constantly promote the process of urbanization, car ownership increasing, leading to parking problems, has become an important factor in China’s social and economic development. Stereoscopic garage can better solve the difficult problem of urban parking. Currently, stereoscopic garage is in steel or cast concrete structures in the world. Building in steel is relatively light weight, high strength, easy construction and installation. However, fire-resistant and corrosion resistance of steel is poor, thermal conductivity coefficient is large, especially in high temperature fire, strength of building element declined rapidly, easily collapse destruction, may cause the collapse of the surrounding buildings, and even casualties. Cast concrete structure with low cost, fire resistance and good corrosion resistance and other characteristics, but in the construction process, there need to provide a large construction site, more construction workers, long construction period, a greater impact on the surrounding and other shortcomings. To meet the parking garage construction on the basis of convenience, and to make up for fireproof performance. In this grim situation, the advantages of prefabricated concrete stereoscopic garage will gradually emerge.In this paper, the prefabricated concrete stereoscopic garage for the study, during the analysis on the basis of overall structure, reinforced concrete stereoscopic garage for the overall analysis and comparison, and classified designed of the component nodes, initial formation of structural design and construction drawings, provide a reference for further research applications of prefabricated concrete parking stereoscopic garage. Specific work completed as follows:(1) Describes the various types, characteristics and design considerations to note parking garage. Finally chose the elevator garage as a research object, and determined the parameters of this parking garage: stereoscopic garage composition structure plane parameters, the height, and the load.(2) According to the design principles of concrete shear wall structure, for five different layers of monocular parking garage and six different combinations of type-storey parking garage for the overall analysis and comparison, select the typical parking garage structure was complete calculation, from lateral displacement and the number of reinforcement to analyze the rationality and economical of its structure, Put forward stereoscopic garage for shear wall structure of high aspect ratio.(3) In structure calculations on the basis of the analysis, For monocular and binocular stereo garage structure of vertical and horizontal components of the decomposition, and according to current design, conducted node design, to ensure the reliability of the overall configuration and the node.
