与3D测量配合360°钢

作者：Cornelia Dietz

Schmid Metallbau, founded as a classic metal workshop in 1993, offers today perfectly crafted products and solutions in the fields of metalworking, stainless steel processing and metal construction. To serve customers on large construction sites or commercial and industrial buildings, a total of 15 employees focus on metal construction and design where high-quality work and a high attention to detail is of utmost importance.

在2017年春季，该公司获得了一个令人兴奋的新项目 - 为在德国拉文斯堡一家医院的屋顶上设计和建造了面向外向的栏杆。为了安装Helipad的内置组件，栏杆以圆形方式沿结构的边缘放置。为了避免所有面向不同方向和扭曲或倾斜的预安装组件，需要对每个持有人进行单独测量和建模。

Closing the steel belt

It was labour-intensive to manufacture a railing running around the helipad’s platform in a circular way. Metal was bent with a special tool, so everything could fit seamlessly when installed on site. A misfit would have caused the circle’s steel pieces not to match.

"It’s just like when you can’t close your belt anymore because you’ve gone past the widest hole,"says Markus Schmid owner of Schmid Metallbau.

In addition to the outward facing railing, a steel net was installed. In a worst-case scenario, the net must withstand catching a falling helicopter.

前往BAU寻找正确的解决方案

Schmid Metallbau decided to visit the BAU exhibition in Munich, Germany, with the goal of finding a solution to these complex 3D measurement needs. The company found the 3D DISTO and approached a colleague who already owned the product. After listening to the colleague’s positive feedback and receiving a more detailed explanation of the product, the firm ordered the 3D DISTO right away.

The high-precision survey was taken from one position only using the 3D DISTO with the aid of an adapter plate mounted on site. The company designed a simple target plate where foremen could mount the tilted, pre-installed, outward facing components of the railing. The 3D DISTO was set up in the centre of the helipad so it couldmeasure all 54 structural components at once。重新定位3D散发器仅与三点方法一致两次后，测量很快就完成了，所有数据均为转移到CAD。

不可能使用常规方法（例如磁带测量或激光距离计）完成这些测量。3D散布能够测量54个偏斜的组件一个位置的毫米精度并相互测量每个组件。

“数据传输简单明了，因此您可以立即开始使用捕获的测量数据工作，”says Schmid."As the person responsible for implementation, I want to be certain that the data is transferred one-to-one into CAD. The measured points are clearly transferred into CAD making easier the preparation of the work and making sure each piece will fit.”

In upcoming projects, Metallbau Schmid already sees many different use cases for its new 3D DISTO, from the installation of glass, metal cladding of outward facing staircases to staircase shape, height and depth.
