Research On Layout Plan Of Prefabricated Building Site

Today,when industrialized construction methods are promoted,prefabricated buildings are increasingly popularized.For engineering projects,the construction site is an important place of origin of the project,and the layout of the construction site is related to whether the project construction can be carried out smoothly.Our country currently lacks research in the field of prefabricated building site layout.Therefore,a scientific and reasonable system layout method is needed to meet the actual needs of prefabricated building sites.This thesis first explains the advantages and development significance of prefabricated buildings,explains the lifting techniques and control points of different types of prefabricated components detailly,expounds the basis and content of general construction site layout,and proposes construction site layout requirements for prefabricated buildings.Secondly,the relationship between the facilities of the prefabricated building site is analyzed,and the relationship between the facilities is quantified from the two dimensions of transportation cost and safety risk.The relationship between the various indicators of the facility is obtained through on-site monitoring and questionnaires,and finally obtained according to the proportional weight the comprehensive interrelationship value between each facility.Furthermore,simplify the construction site and facilities of the prefabricated building into a grid system model,formulate the constraints of the construction site layout,select the location of the facility based on the previous correlation value as the objective function,and solve the facility step by step using the idea of multi-stage decision-making The optimal location of the layout,to get the final prefabricated building layout optimization plan.Finally,empirical analysis is carried out with specific engineering cases,and the engineering cases are optimized with the method of this thesis.The original site layout plan of prefabricated buildings and the optimized layout plan of this paper are compared and analyzed to verify the feasibility of the method.This thesis focuses on the characteristics of prefabricated buildings,taking into account both transportation costs and safety risks,and comprehensively analyzes the internal connections between buildings and facilities.The internal connections are used to rationally locate the facilities and make the layout of prefabricated building sites more scientific and reasonable,it provides a reference method for the construction site layout of prefabricated buildings.
