Steel structure inhaul cable construction method based on BIM (Building Information Modeling) technique

Abstract

The invention discloses a steel structure inhaul cable construction method based on a BIM (Building Information Modeling) technique, and relates to the technical field of stadium engineering. The steel structure inhaul cable construction method based on the BIM technique comprises the following specific steps of (S1) establishing a steel structure and inhaul cable model through BIM software according to a construction drawing; (S2) dividing inhaul cable construction flow sections according to a construction progress plan, determining the inhaul cable installation and tensioning sequence, wherein the installation sequence is started from the head end to the tail end; and tensioning inhaul cables step by step in batches according to the symmetry principle after the inhaul cables are pre-tightened, and tensioning 50% of design prestress from the first batch to the last batch. According to the steel structure inhaul cable construction method based on the BIM technique, a method of combining BIM technique auxiliary simulation, optimization and site construction is adopted, so that the effect of quality control in advance and in the event is achieved, the inhaul cable construction safety is ensured, the construction progress is accelerated, the construction quality is improved, the method can be widely applied to construction of stadium type steel structure inhaul cables, and inhaul cable machining drawings are deepened and optimized.

Description

technical field [0001] The invention relates to the technical field of venue engineering, in particular to a BIM technology-based steel structure cable construction method. Background technique [0002] With the advancement of science and technology and the needs of the development of national sports, the construction of domestic sports venues is currently in full swing, and the construction of steel structure cables for sports venues is inevitable. Steel structure engineering has the characteristics of large spans, complex structural shapes, and many applications for cable construction. [0003] The construction of traditional steel structure cables is limited to designers analyzing the data and information of steel structure cables in the past, and verifying the safety of the construction through checking calculations; during construction, it is difficult to guarantee the conformity of the cable dimensions, and there are also inconsistencies in construction safety. Stabili...
