湾曲した壁の杭打ち

円弧壁は 2 つの状況に分けられます: 内側のアークは光を認識し、外側のアークは光を認識します: 滑らかな表面が内側の円弧の場合, 半径が1つの場合, 弦の長さとアーチの高さを使用して半径を計算できます, in the case of multiple radii, We must use the coordinate system to determine the joints of different radii and the radii of the segments.

When the smooth surface is an outer arc, we must use the coordinate system to fix the point. When taking the point, we must find more points. When measuring, it must be perpendicular to the axis we set. Then use three points to draw the arc, and finally get the best radius. The curved wall should be processed with a circular arc with a radius as far as possible, or connected with as few circular arc segments as possible. The arc should be processed immediately after setting out. Come out and check to make sure it’s accurate.

It is more difficult to stake out special-shaped arc plates! First of all, we must understand the concept of special-shaped arc plate, and we will talk about examples in the following typical cases. The upper and lower end surfaces of the ordinary arc plate are two parallel and equal sectors, and the sides on both sides of the side are parallel line segments; the upper and lower end surfaces of the tapered arc plate are two parallel but unequal concentric sectors, and the sides are two Extend the intersecting line segments; the difference of the special-shaped arc plate is that the two sides are different-plane line segments that are not in the same plane.

To stake out a special-shaped arc plate, you must first find out the design rules of the arc-shaped wall, divide the arc-shaped wall into areas, and stake out in sections. 一般的に, several appropriate elevations are taken to release the outline of the civil or steel frame, or you can directly Release the finished surface line of the stone; at the same time, pay attention to the mutual positional relationship between the finished surfaces of each level, and it is required to accurately describe the shape of the curved wall on the computer.

For this special product, the requirements for lofting, processing and construction are more closely coordinated, and the benchmark is very important, which must be strictly consistent
