Laminated slab cantilever I-shaped steel construction method based on BIM (Building Information Modeling) technology

Abstract

The invention relates to the field of construction engineering technology, and particularly discloses a laminated slab cantilever I-shaped steel construction method based on the BIM (Building Information Modeling) technology. The laminated slab cantilever I-shaped steel construction method based on the BIM technology specifically comprises the steps of establishing models; combining the models; performing collision analysis; according to the design scheme of a cantilever frame, calculating the stress of an anchor ring, and accurately placing the anchor ring to serve as a reference object of a laminated slab model; establishing a laminated slab supporting frame and a cast-in-place belt formwork model, optimizing the positions of vertical rods and supporting beams, enabling the vertical rods of the supporting frame at the anchor ring position to be arranged in an infilling mode, and achieving an jacking effect on a floor slab; performing data analysis and collision optimization; S5, processing, positioning, manufacturing and forming; mounting a laminated slab; binding upper side rebars, pouring concrete, and curing; and erecting the cantilever frame. According to laminated slab cantilever I-shaped steel construction method based on the BIM technology provided by the invention, collision with reinforcing steel bars, embedded pipelines and plate bottom keels can be effectively avoided, the construction efficiency is improved, and waste of manpower, financial resources and time is avoided.

Description

technical field [0001] The invention relates to the technical field of cantilever erection, and more specifically, relates to a construction method for cantilevered I-beams of laminated plates based on BIM technology. Background technique [0002] In the construction process of the prefabricated laminated slab, the steel bar system is complex and the number of wire pipes is large. The I-beam anchor ring of the cantilever frame generally adopts the post-opening construction technology, which has not been considered in the design stage, and there are certain structural safety hazards. In addition It is very difficult to open holes afterward, and the position of the holes may conflict with the position of the steel bars, pre-embedded pipelines, and slab bottom keels, resulting in the failure of the normal installation of the anchor ring, low construction efficiency, and may lead to repeated holes, which will affect the appearance quality of the continuous beam concrete. The cos...
