Arc-shaped setting-out tool

Abstract

The invention relates to an arc-shaped setting-out tool. The arc-shaped setting-out tool comprises a central rotating shaft; the upper end and the lower end of the central rotating shaft are connectedwith an upper fixing disc and a lower fixing disc correspondingly; two bobbins capable of rotating independently are mounted outside the central rotating shaft side by side; angle scales are arrangedon the upper fixing disc and the lower fixing disc correspondingly; the bottom of the lower fixing disc is fixedly connected with a detachable base; and measuring ropes are wound in the bobbins, andthe ends of the measuring ropes are connected with fixing bolts used for being connected with marking tools. Drawing or setting-out can be conducted quite conveniently and visually by the arc-shaped setting-out tool according data such as the radius, angle and radian of a circle or an arc; and precision is high, the structural principle is simple, operation is convenient and rapid, and the construction efficiency is high.

Description

technical field [0001] The invention relates to a construction setting-out tool, more specifically, to an arc-shaped setting-out tool. Background technique [0002] The construction setting-out tool is a tool commonly used in engineering. In engineering construction, it is often necessary to lay out or draw various complex shapes, lines or patterns on the paved ground, building structures, templates, steel plates and other materials, especially for all kinds of ground paving, when the design pursues creativity and effect , often use various complex shapes, lines or patterns, but we directly use the traditional wire-laying methods and tools, which is troublesome, difficult to operate, low in efficiency, and it is difficult to ensure the smoothness of the curve and the regularity of the pattern. Accuracy, or it is often difficult to construct when there are only points and points but not connected into lines during construction. For this reason, we need a method that can be m...

In engineering construction, it is often necessary to lay out or draw various complex shapes, lines or patterns on the paved ground, building structures, templates, steel plates and other materials, especially for various ground pavements, when the design pursues creativity and effects , often composed of various complex shapes, lines or patterns, but we directly use traditional wire-laying methods and tools, which is troublesome, difficult to operate, low in efficiency, and difficult to ensure the smoothness of the curve and the regularity of the pattern. Accuracy, or it is often difficult to construct when there are only points and points but not connected into a line during construction. For this reason, we need a more convenient and better guarantee for the smoothness of the curve and the regularity and accuracy of the pattern. , a pay-off tool that can greatly improve construction efficiency to facilitate construction
