Construction method of spiral-rising-type reinforced concrete structure based on BIM

Abstract

The invention discloses a construction method of a spiral-rising-type reinforced concrete structure based on BIM. A formwork and a supporting system can be automatically generated, the formwork splicing design can be automatically completed, three-dimensional construction simulation can be conducted, intelligent materials are optimized, and the use amount of various materials can be counted and precisely calculated. A BIM software technology is used for conducting three-dimensional modeling on a spiral-rising-type building structure, the splicing size, the supporting system and a safety calculation book of the building structure are determined, and construction workers conduct construction by directly in combination with a three-dimensional model according to a formwork scheme; by using the BIM technology, the speed of designing the formwork is high, the precision of designing the formwork is high, the loss of a supporting rack is reduced, the use efficiency of steel pipes is improved,and the situation is avoided that in the process of calculating the use amount of the materials of the framework and a scaffold, a common artificial design framework is changed, and the materials arewasted due to an unreasonable formwork splicing mode; the energy is saved, the environment is protected, and the engineering construction cost and the construction difficulty are reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a BIM-based construction method for a spiral-rising reinforced concrete structure. Background technique [0002] BIM technology (Building Information Modeling) is usually translated as a building information model. Model-based information management or building information management is based on the relevant information data of construction projects, manages three-dimensional building models, and simulates the real information of buildings through digital information simulation. It has eight characteristics of information completeness, information relevance, information consistency, visualization, coordination, simulation, optimization and graphing.

Problems solved by technology

[0003] With the development of diversification of buildings, there are more and more reinforced concrete structures with novel designs and complex shapes. A kind of building that is similar to the shape of a conch in design form and adopts an elliptical spiral rising reinforced concrete structure appears in venues all over the world. In the design, the construction of this kind of structure is difficult in measuring and setting out, steel bar binding, formwork support, and concrete pouring, which is not only labor-intensive, but also difficult to guarantee the molding quality

The construction technicians at the construction site have been exploring the use of BIM technology combined with virtual simulation technology, GPS precise measurement and positioning, concrete pouring and other construction techniques to improve the construction quality of such buildings, shorten the construction period, and achieve better design results , but as far as the current statistical results are concerned, there are still certain technical defects in this field
