The method comprises: establishing a three-dimensional model of a prefabricated part and a cast-in-place structure; analyzing and optimizing the prefabricated parts according to a prefabricated part splitting design principle and the key nodes; carrying out collisiondetection on the integrated model and carrying out optimal design on the prefabricated part; creating a preliminary measure model and carrying out hoisting simulation analysis on the prefabricated part; outputting various engineering drawings, engineering quantity lists and analog videos on the basis of the model; and engineering three-dimensional site arrangement and analysis are carried out, and a site arrangement diagram is output. The method is based on the BIM technology. The invention discloses a method for designing a precast concrete member. Precision deviation possibly existing in prefabricated part production is considered in advance, a set of perfect prefabricated part hoisting process is formed by checking possible problems of the prefabricated parts in the hoisting process and conducting optimization design on the prefabricated parts in a targeted mode, and it is guaranteed that follow-up on-site actual construction is conducted smoothly.

Description

Technical field [0001] The invention relates to an optimization method for building structure engineering, in particular to an optimization method for assembled precast concrete structure engineering based on BIM technology. Background technique [0002] Prefabricated buildings can effectively reduce the pollution of construction sewage, dust, harmful gases and construction noise during the construction process, reduce the impact of construction on the surrounding environment, and promote the health of the construction industry while improving the refinement of construction projects sustainable development. And according to my country's urban planning and construction management, it is clearly proposed that the proportion of prefabricated buildings should reach 30% in about ten years. Therefore, the prefabricated structure system of buildings is the general trend of the construction industry in the future. [0003] But at present, because construction engineering designers general...

Problems solved by technology

[0003] However, at present, because architectural engineering designers generally design prefabricated components through two-dimensional means, and at the same time, the designers, component producers, and construction parties of most engineering projects belong to different units, so it is often difficult for engineering designers to comprehensively Considering the production and on-site hoisting of prefabricated components, it often leads to collisions between adjacent prefabricated components, collisions between prefabricated components and cast-in-place components, and collisions between prefabricated components and temporary measures during the subsequent on-site hoisting of prefabricated components. The passive response of prefabricated components to solve the collision problem and then repair it not only caused a serious waste of materials, but also greatly affected the quality of the building, reduced the efficiency of building construction, and increased the cost of building construction
