Problems solved by technology
The classification and statistics of materials are still done manually, which is not intuitive and inconvenient. The workload of design, calibration and review is huge, difficult and error-prone, and the amount of steel bars calculated manually is rough, which cannot guide refined procurement and downloading. Material, processing, binding and installation
[0003] At the same time, because there is no accurate and complete 3D information model of steel bars, during the construction process, construction personnel must make allowances and on-site adjustments based on their own understanding of drawings and construction experience, thereby affecting construction quality and efficiency. Therefore, it is urgently needed A tool for rapid 3D reinforcement design of typical complex structures such as volute structures

Embodiment Construction
[0036] Such as figure 1 As shown, the present invention determines the center line of the section of the volute and the center point of the volute through the surface geometric topology information of the volute structure (or the volute type parameter table), and calculates each The number of steel bars in the wrap angle, the position of the circumferential reinforcement point, the normal plane where the reinforcement point is located, and the surface of the volute structure are intersected to obtain the circumferential auxiliary line, or the circumferential auxiliary line is obtained through the calculation of the volute type parameter table. Offset the circumferential auxiliary line along the normal direction, and the offset distance is the thickness of the volute concrete cover to obtain the circumferential steel bar axis and circumferential steel bar; offset the circumferential auxiliary line to the thickness of the steel bar cover in the water direction to offset The oute...

The invention relates to the field of rebar graph design and provides a three-dimensional rebar arranging method used for a volute structure, so three-dimensional rebar arranging can be achieved for rebar of the volute structure. The method mainly comprises steps of determining a central line of a volute fracture surface, a central point of the volute and the central axis of the volute; according to the wrap angle start-stop range, calculating the number of circumferential rebar and rebar arranging point positions in the range; generating circumferential auxiliary lines on circumferential rebar points; offsetting the circumferential auxiliary lines to obtain circumferential rebar axes; determining and generating pipelined rebar arranging points and pipelined rebar axes; and calling a rebar template to generate three-dimensional objects of the circumferential rebar and pipelined rebar for the circumferential rebar axes and the pipelined rebar axes, thereby generating a volute three-dimensional rebar object. The method is suitable for rebar of the volute structure.
Description
technical field [0001] The invention relates to the field of steel bar diagram design, in particular to a three-dimensional reinforcement method for a volute structure. Background technique [0002] The volute is an important part of the hydropower plant, and its body structure is very complex. The surface of the volute is composed of multiple complex curved surfaces, and each curved surface piece changes discontinuously. At present, most of the drawing methods for the reinforcement diagram of the volute structure adopt two-dimensional drawing to draw the reinforcement diagram of the key typical structural section. However, due to the complex structure of the volute, the types and types of steel bars vary a lot, and the length, diameter, and spacing vary a lot, so it is inconvenient to group, draw, and calculate statistics. Calculate the number of steel bars and the length of steel bars by hand, and draw a steel bar diagram. The classification and statistics of materials a...
