Abstract

The invention discloses a method for determining the length of a cable in a prestressed state of a cable structure. 2. Use BIM three-dimensional visualization software to model the prestressed state BIM model; 3. Measure the length of the cable as the cable blanking length; 4. Mark the cable blanking length and marking force value in the drawing ;5. After the cable structure is installed, perform spatial positioning and 3D scanning on the cable structure to obtain the real state 3D coordinates; 6. Establish a real state BIM model in the BIM 3D visualization software, measure the length of the cable, and obtain the length of the cable after construction , compared with the cutting length of the cable, determine whether to take corresponding technical measures or adjust the construction plan of the cable structure; the present invention can optimize the stress state of the cable structure, so that each cable bears an appropriate tension, thereby ensuring the cable structure the overall stiffness.

Description

Technical field [0001] The present invention relates to the technical field of prestressed structural products, and in particular, to a method of prestabing the cable length determination method. Background technique [0002] Large-span prestressed steel structure is one of the important criteria for a national building science and technology. It is also a symbol of a national civilization development. China's large-span prestressed steel structure is in response to the requirements of the times, in recent years, architectural shape is flexible and novel The engineering layer has emerged and has been widely used. [0003] The cable structure belongs to the prestressed steel structure system, and its structural characteristics are characterized by the main force framework, so that the structure is composed of a large number of cable, and the cable requires the application of the prestressed to form effective structural rigidity to resist external load. The overall rigidity of the ...
