Embodiment Construction

[0014] In order to fully understand the present invention, many details are mentioned in the following detailed description, but those skilled in the art should understand that the present invention can be implemented without these specific details. In the embodiments thereof, well-known methods, procedures and components are not described in detail so as not to unnecessarily obscure the embodiments.

[0015] The shape of the multi-curved and twisted special-shaped structure building is non-circular or non-elliptical, but a multi-curved and twisted structure. In the "Mobius ring" of this structure, every steel structural member is curved The direction, arc, and length are different. As a result, it is impossible to use conventional methods to survey the external contour data of the multi-bend and torsion shaped structure after completion.

[0016] When measuring the outer contour lines of traditional normal building structures and regularly findable building structures, as long as...

Abstract

A method for acquiring outer contour data of a multi-curve torsional special-shaped structure building comprises the steps as follows: the outer contour projection points of 'ribs' of the multi-curve flexural-torsional special-shaped building are determined through 3D modeling; the height of the multi-curve flexural-torsional special-shaped building is determined by acquiring and using the apron absolute elevation and roof height point absolute elevation corresponding to the multi-curve flexural-torsional special-shaped building. The method has the benefits as follows: the technical defect that the outer contour data of the multi-curve flexural-torsional special-shaped building cannot be measured with the prior art is effectively overcome; the method has the characteristics of being high in use accuracy, convenient in measurement and high in measurement effect.

Description

Technical field [0001] The invention relates to the field of building surveys, and in particular to a method for collecting data on the external contour of a building with multiple twists and turns. Background technique [0002] During and after the construction of the building, in order to ensure the construction quality of the building, it is usually necessary to monitor the actual building parameters of the building to ensure that the completed building meets the design standards. [0003] There are mature survey methods and methods for normal building structures and regular and findable building structures. However, for special-shaped buildings, especially for the outer contour data of multi-curved and twisted structures, conventional survey methods and methods cannot be used. collection. [0004] Therefore, a special technical method is needed to solve the problem of data acquisition of the external contour of the multi-curved and deformed building. Summary of the invention [...
