Modelling control method of decorative surface

Abstract

The invention provides a modelling quality control method of a decorative surface. The method comprises the following steps of A) examining and verifying construction drawings, finding out a circle centre of a surface model, decomposing an irregular surface into a plurality of circles, and determining the circle centre, a radius, an arc length and a positioning coordinate; B) decomposing and optimizing the surface model by using computer aided design (CAD), wherein field sizes and paying-off is required to be in accordance with the designed drawings strictly; using a computer to assist the paying-off, so that precision can be ensured; and C) inspecting and checking quality for nodes constructed on a cambered surface, and reducing unnecessary dimensional deviations. The flatness of the cambered surface is ensured, and firmness and construction quality are ensured. By the method disclosed by the invention, the stability and firmness of the steel structure foundation of the surface model, and the flatness and radian of the cambered surface meet the specified requirements. Impression effects meet a predetermined aim, the percent of pass is above 95%, and secondary rework is avoided.

Description

technical field [0001] The invention relates to a method for controlling the modeling of a decorative curved surface. Background technique [0002] With the continuous deepening of architectural design, people are no longer satisfied with square and regular shapes, especially in the decoration industry, curved surface shapes are more widely used. How to better shape complex curved surfaces has become a technical problem. In recent years, the quality control of decorative curved surfaces generally adopts the following schemes: [0003] 1. The base steel structure construction team adopts long-term fixed and long-term cooperative welder teams to weld, and the wood veneer on the top of the wall is directly entrusted to the veneer processing factory to process and install the finished wood veneer. [0004] 2. The grassroots steel structure construction team is looking for a professional steel structure welding team for construction, and imported veneer veneer is used in the ven...

Problems solved by technology

[0007] (1) The special construction plan is unreasonable;

[0008] (2) The operation process is not implemented according to the specifications and approved plans, mainly reflected in: the steel structure foundation is unstable and there is shaking; the surface shape deviates too much from the original design intention, the curvature of the surface is not smooth, and the yin and yang angles are not straight

The flatness is not high, appearing wavy
