Furthermore, the second scale is transparent ya keli finished piece, set up single scale mark on the second scale, the zero point of single scale mark is located the lower extreme of second scale, the back of second scale sets up the draw-in groove, two the fixture block joint in the draw-in groove.

Furthermore, a protective soft rubber strip is bonded on the cambered surface at the bottom of the reference plate.

Further, first scale passes through fix with rivet on benchmark board upper portion, the handle passes through fix with rivet the back of benchmark board, the both ends of first scale all set up shutoff aluminum plate.

Furthermore, the reference plate is an acrylic part, the first graduated scale and the handle are both made of stainless steel, and the adapter slide block is made of aluminum alloy.

An arc curtain wall measuring method comprises the following steps:

s1: butting the bottom cambered surface of the reference plate with the arc-shaped curtain wall, aligning the zero point of the first graduated scale with the butt joint point, and aligning the zero point of the second graduated scale with the zero point of the first graduated scale;

s2: sliding the second graduated scale leftwards to reach the left end of the arc-shaped curtain wall, then sliding the second graduated scale downwards to contact with the arc-shaped curtain wall, and recording the reading numbers of the first graduated scale and the second graduated scale at the moment, namely the coordinate of the left end point of the arc-shaped curtain wall;

s3: sliding the second graduated scale rightwards to reach the right end of the arc-shaped curtain wall, then sliding the second graduated scale downwards to contact with the arc-shaped curtain wall, and recording the readings of the first graduated scale and the second graduated scale at the moment, namely the coordinate of the right end point of the arc-shaped curtain wall;

s4: and calculating the radius of the arc of the cross section of the arc curtain wall according to the coordinates of the left end point and the right end point of the arc curtain wall, and then calculating the radian and the arc length of the arc curtain wall according to the radius.

Along with social progress and modern development, building arc curtain wall is more and more popular because it is rich in pleasing to the eye, science and technology sense, needs to measure data such as camber in the work progress of arc curtain wall, and prior art personnel traditional measurement mainly relies on the eye measurement, but this kind of measuring method error is great for the installation effectiveness of arc curtain wall is low. However, there is no tool and method for accurately measuring the arc. In order to improve the accuracy of the measurement, one skilled in the art may think of a reference elbow arc measuring tool, such as a circle-center-free arc bending radius measuring ruler and an elbow bending radius measuring method disclosed in patent publication No. CN 103234432 a. The measuring scale is symmetrically connected with a left supporting leg and a right supporting leg at two ends of a cross beam respectively, a telescopic ruler is connected at the center of the cross beam, and the telescopic ruler moves up and down along the direction vertical to the cross beam. When in measurement, firstly, the inner arc or the outer arc of the bent part of the bent pipe is divided into a plurality of equal parts, and then the arc height of a local arc segment taking each equal division point as a starting point is measured from the two directions of the inner arc or the outer arc by adopting a circle-free arc bending radius measuring scale; calculating to obtain the radius of each local arc segment; and finally, calculating the average radius value of each local circular arc section so as to calculate the bending radius of the bent pipe. However, the arc measuring scale and the method disclosed in this patent document are required to divide the curved surface of the bent pipe into equal parts before measurement, calculate the radius of the arc from the arc height of each divided arc, and average the obtained radius values to obtain the radius of the curved pipe arc. Therefore, if the method is directly used for measuring the arc curtain wall, the following problems can be caused: (1) the arc curtain wall of the building is usually large in size and about 4 meters in length, so that the arc surface is difficult to equally divide; (2) by means of sectional measurement, radius calculation and averaging, if errors occur during sectional measurement, errors also occur during subsequent averaging, and measurement accuracy cannot be guaranteed; (3) the radius of the arc surface can only be measured, but the central angle of the arc surface cannot be measured, and the radian and the arc length of the arc cannot be measured. Therefore, the measurement tool and the measurement method of the present application are not easily conceivable by those skilled in the art based on the patent documents.

Compared with the prior art, the invention has the following beneficial effects:

according to the arc-shaped curtain wall measuring tool, the reference plate is used for butting the arc-shaped curtain wall, and the first graduated scale and the second graduated scale on the reference plate slide relatively, namely the second graduated scale slides up and down, left and right on the first graduated scale and contacts with the arc-shaped curtain wall, so that data of any point on the arc-shaped curtain wall can be measured, the measurement is convenient, the measured data is accurate, and errors caused by a traditional visual measurement method are avoided; in addition, through measuring the data of arc curtain both ends point, can calculate information such as radius, radian, arc length of arc curtain, guarantee the accurate measurement of arc curtain.

In addition, a protective soft rubber strip is bonded on the cambered surface of the lower part of the reference plate, so that on one hand, the surface of the arc-shaped curtain wall is prevented from being abraded, on the other hand, the friction force between the reference plate and the arc-shaped curtain wall can be increased, and the situation that the measured data is inaccurate due to shaking or sliding of the reference plate in the measuring process is prevented; switching slider sets up in first scale middle part spout to drive the second scale and remove, the back of second scale sets up the draw-in groove, and the fixture block joint of switching slider tip is in the draw-in groove, thereby the second scale can slide from top to bottom, measures.

In addition, the second graduated scale is made of a transparent acrylic part, so that the numerical value reading of the first graduated scale at the lower part of the second graduated scale is not influenced during measurement; the first scale adopts bidirectional scale lines, the zero point is positioned in the middle, and when the zero point is butted with a certain point of the arc-shaped curtain wall, the arc surfaces on the two sides of the butted point can directly obtain more accurate readings, so that the measurement convenience is improved; the back of benchmark board sets up the handle, does not influence the sliding range of second scale on the one hand, and stability when on the other hand can guarantee the benchmark board butt joint guarantees measurement accuracy.
