Embodiment Construction

[0023] A three-dimensional model-assisted special-shaped formwork design and installation method proposed by the present invention will be further described in detail below in conjunction with specific implementation cases.

[0024] The concrete lining type of the tail water diffusion section of the underground powerhouse of a certain hydropower station is a gate-shaped hole with rounded bottom and rounded corners. The net size of the section changes gradually along the axis direction, and the curve changes complexly. Each template is unique, with different shapes and sizes. However, in civil engineering, the design unit usually only provides the detailed dimensions of the front and rear sections of the gradual tunnel. In this implementation case, the method of using a three-dimensional model to assist the design and installation of special-shaped formwork is as follows:

[0025] 1. Establish a three-dimensional model of the overall surface of the concrete lining formwork pan...

Abstract

The invention discloses a method for designing and installing an auxiliary special-shaped template of a three-dimensional model. On the basis of establishing a special-shaped concrete formwork panel three-dimensional curve surface model, a body sectioning and measuring method is adopted to precisely design the special-shaped template, an accurate basis is provided for installing and lofting, and by means of the template specification number and the visualization character of the three-dimensional model, the special-shaped template is quickly installed. By means of the method, accurate data of size of each template can be provided for large special-shaped concrete structures, the template design time is saved, the template installation efficiency is accelerated, and the project quality is improved.

Description

technical field [0001] The invention relates to the technical field of concrete construction, in particular to a method for designing and installing a special-shaped formwork assisted by a three-dimensional model. Background technique [0002] In order to meet certain practical, safety, and aesthetic requirements, some engineering structures are usually designed as irregular shapes with complex body curves, high requirements for pouring quality, and extremely high requirements for corresponding formwork. Special-shaped steel formwork can meet higher and higher construction precision requirements and ensure that the permanent engineering concrete structure meets the specification requirements. However, in civil engineering, the design unit usually only provides partial cross-sectional drawings of the special-shaped parts, which cannot show the details of the change of the curved surface at any cross-section. The construction unit can only estimate the compartmental sections a...
