The Seismic Performance Analysis And Standardized Of Steel Unitbathroom Connection

The unitbathroom is a new type of industrial production collectively bathroom products collectively.The main form of outer frame structure of the product is constituted by roof,wall panels and waterproof chassis.A set of molding products is an independent sanitary unit which can be achieved that wash a face,shower,toilet and other functions within the limited space.In the design of the unitbathroom,the connection of each component not only having no strict specification standard to follow,but also it is mostly according to the requirements of structure to arrange the connection program without considering the mechanical characteristics and mechanical properties of the structure,and it does not take the influence of seismic load to the structure into account.What's more,it has no steel unitbathromm to adapt to the steel structure industrial development.According to need,this paper puts forward a new structure program that suite for the steel unitbathroom of prefabricated steel structure.To look forward to the new program can promote standardization of indoor decoration.To make the new steel unitbathroom to be a unit bath with seismic ability,the seismic action has been taken into consideration in this paper.It can improve the stiffness and stability of the bathroom unit greatly,ensure the bathroom unit that does not occur local damage because of insufficient strength of the connection points and does not occur overall damage because of insufficient strength of the SMC problem.The angle as the main material of new steel unitbathroom make the connection between unitbathroom and main structure to be possible,and it's helpful to the component design standardizationThere are two new structure program that connecting with the main structure of the unitbathroom.Plan A:the bolt connection of unitbathroom and column;Plan B:the bolt connection of unitbathroom and secondary beam.Including the component type,size,quantity and the specific structure of form of the new type bathroom unit,the connection type with the main structure,the distance with the main structure.Finite element software ABAQUS is used to analysis the structure of the new bathroom unit of elastic under more severe earthquake loads and elastic-plastic analysis under rare earthquake loads.According to the results and stress cloud of the structure under horizontal seismic action,contrast and analysis of the reliability of the program.Validation that the program can withstand more severe earthquake action.And then select a representative top node,the connection node of Support and the support connection place to analyze the stress of the node.Analysis shows that this program can meets the requirement,and can improve the stiffness,strength,and stability of the bathroom unit greatly,and a have a reliable connection and anchoring with the main structure,ensure the fittings of bearing or support can passed the seismic action on the bathroom unit on to the main structure completely.To make bathroom unit does not affect the normal use function after suffered earthquake intensity effect,and does not occur local damage because of insufficient strength of the connection points,does not occur overall buckling and overall overturning.This paper choose the worst possible combination form dimensions to analysis.Analysis shows that the designed connection and the angle can meet the requirements of all different sizes.And identify the specific connection form,the specifications of the angle,the size of the level of support,the number of fittings,bolt type,the plan of the structure and component.And then the standardized component size and number of tables,the structure,the connection and its graphic detail are given out.According to the characteristics of unitkitchen and unitbathroom,summarizing the design,the construction installation method and the quality acceptance criteria of unitkitchen and unitbathroom.For the pipelines and ware is the key to unitkitchen and unitbathroom,the paper finally summarizes the construction installation method,the finished product protection and the matters needing attention of pipeline and ware of unitkitchen and unitbathroom.
