Installing method for large open-type stone curtain wall and based on BIM

Abstract

The invention discloses an installing method for a large open-type stone curtain wall and based on BIM. By utilizing the BIM technology, a three-dimensional information model is established accordingto a design blueprint provided by a designing institute, a stone model is established first, the principles of lateral symmetry, longitudinal symmetry and maximum using of stone are fully considered during establishing, and after stone layout is determined, a secondary keel model and a main keel model are sequentially established; after a main keel is determined, the specification and the size ofan embedded part are determined by utilizing the calculating function of the BIM structure, an embedded part model is established, and finally, a model of a waterproof plate is established; after model establishing is completed, and a flat section construction drawing and on-site three-dimensional technical disclosure are provided by unitizing BIM software. With application of the technology, advantages of three-dimensional data are fully exerted, the utilization rate of the stone is improved, and waste is avoided; and the final positions of the main keel and the embedded part are determined at the early stage of construction, the phenomenon of rework due to the fact that the position of the embedded part is not proper because of layout adjustment in the construction process in the traditional technology is reduced, using quality and safety of the curtain wall are enhanced, and the communicating effect is further improved by the three-dimensional model.

Description

technical field [0001] The present invention relates to a building construction method, more specifically, relates to a method in the installation of a large open stone curtain wall based on BIM. Background technique [0002] The construction of the open stone curtain wall is still a difficult point in the construction. It is difficult to show the effect of the curtain wall after the two-dimensional design drawings. The construction unit checks whether there are any missing items in the drawings based on experience in the early stage, and infers the plane layout based on the size of the building plan. , The position of the embedded parts, due to the limitation of receiving two-dimensional, it is difficult to fully consider the rationality of the drawing. During the construction process, the position deviation of the embedded parts is large, and the rear embedded parts need to be rearranged, resulting in a large amount of rework, and serious safety hazards caused by the rear ...

[0002] The construction of the open stone curtain wall is still a difficult point in the construction. It is difficult to show the effect of the curtain wall after the two-dimensional design drawings. The construction unit checks whether there are any missing items in the drawings based on experience in the early stage, and infers the plane layout based on the size of the building plan. , The location of the embedded parts, due to the limitation of receiving two-dimensional, it is difficult to fully consider the rationality of the drawing

During the construction process, the position deviation of the embedded parts is large, and the rear embedded parts need to be rearranged, resulting in a large amount of rework, and serious safety hazards caused by the rear embedded parts. Due to the unreasonable layout, there is a lot of waste in the use of stone materials , the disclosure is not in place, and the waterproof treatment of the open stone curtain wall has not been paid attention to. These have affected the later use. The construction quality of the traditional open stone curtain wall basically depends on the quality of the drawings and the experience of the curtain wall construction unit, and there is a possibility of rework. It will increase the cost of materials and affect the construction efficiency
