Embodiment Construction

[0033] Below in conjunction with accompanying drawing and embodiment the present invention is further described: as figure 1 Shown is the assembled state of the curtain wall panels of the present invention. The figure shows an embodiment of vertical bending. The numbers in the figure are the calculation results of the bending radius after vertical bending and fitting through the technical solution of the present invention. For the overall curtain wall effect, see Figure 4 . Before the technical solution of the present invention, the splicing gaps and height edge errors caused by panel installation far exceeded the standard requirements. If the reverse ruler was measured completely according to the state of the site, the appearance of the building would be out of shape. The solution of the present invention can greatly reduce the installation error by the following steps, and better complete the design intention of the building appearance.

Abstract

The invention relates to a single-curved plate fitting hyperbolic modeling method for curtain wall design and construction. The method comprises the steps of acquiring preliminary measurement point data; determining plate bending arc radius by an optimal algorithm; then, carrying out plate form-finding operation to obtain a glass processing model. According to the method, theory space model formation logic is selected to be maintained, and key modeling constraint data such as grid division level elevation and grid division parts in a unit interval is controlled. The grid division size is adjusted according to the actual status of a steel structure, so that all curtain wall grid division lines are maintained to be consistent with the variation trend of main structure abnormity; under the premise that the design idea of the original building is maintained visually, the adjusted grid division lines are close to the structure in reality, so that the installation error is greatly reduced.

Description

technical field [0001] The invention relates to the design and construction of a building curtain wall, in particular to a method for designing and constructing a curtain wall to fit a hyperbolic shape with a single curved arc plate. Background technique [0002] Special-shaped structures often appear in some special-shaped curtain wall projects. The problem with the special-shaped main structure is that it is difficult to restrain its own construction, unloading and other errors, and the error range may be tens to hundreds of millimeters. However, the curtain wall system is a precise component matching relationship, and the error needs to be controlled at the millimeter level. Usually in this case, the error of the main structure will be absorbed by building a sub-keel on the main structure. However, for some projects with high permeability requirements, the method of building sub-keels is not acceptable. At this time, if the curtain wall skin is completely implemented ac...
