A fixed-distance reinforcement method suitable for complex and simple surfaces

Abstract

The present invention relates to the three-dimensional drawing field, and provides a distance reinforcement placement method suitable for a complex surface and a simple surface. The distance uniform reinforcement placement of a plurality of complex surfaces and random multi-section guide lines is realized according to the various reinforcement placement rules. The distance reinforcement placement method suitable for the complex surface and the simple surface mainly comprises: selecting and dispersing a reinforcement placement surface; performing triangulation network normal offset; performing reverse reconstruction to generate a reinforcement placement surface after offset; determining the reinforcement placement guide lines; generating a reinforcing steel bar axis based on the reinforcement placement guide lines; generating a reinforcing steel bar three-dimensional object based on the reinforcing steel bar axis; and displaying and storing the reinforcing steel bar three-dimensional object. The distance reinforcement placement method suitable for the complex surface and the simple surface is suitable for the distance reinforcement placement of the complex surface.

Description

technical field [0001] The invention relates to the field of three-dimensional rendering, in particular to a fixed-distance reinforcement method suitable for complex curved surfaces and simple curved surfaces. Background technique [0002] Complex curved surfaces: curved surfaces are relative to planes; complex curved surfaces are relative to simple curved surfaces such as cylinders, spheres, and cones. In the practice of civil engineering, complex surfaces can be divided into regular complex surfaces and free-form surfaces. The surface of underground water diversion and traffic tunnels of various cross-section types, the overflow weir crest structure of the water inlet, and the gradient section structure of various special-shaped structures belong to regular and complex surfaces; while the profiles of parts such as turbine blades are free-form surfaces. [0003] Spacing bars: Bar spacing is the distance between two individual bars. Generally speaking, the spacing between ...

[0006] Judging from the published literature and data, no fixed-distance reinforcement software tools and methods applicable to complex and simple surfaces in the 3D model space have been found to realize multiple complex surfaces, arbitrary multi-segment guide lines, Regular and evenly spaced bars

Since there is no ready-made professional software for 3D modeling of steel bars, the workload of 3D modeling of steel bars is huge, and it is a solid model. With the continuous increase in the number and types of steel bars, whether it is the limitation of computing memory, display speed, or modeling work In terms of volume and difficulty, it is a huge challenge

Especially for concrete structures with multiple complex spatial surfaces, it is impossible to quickly batch, quickly locate, and quickly generate 3D models to facilitate later checks, reviews, and material classification statistics, and cannot meet the rapid and accurate requirements of engineering design. Therefore, It is particularly important to develop new methods that can efficiently deal with the 3D layout and real-time display of complex spatial surface structures
