As shown in Figure 2, it is known that the radius R of arc structure 8 to be measured in building structure, need to measure the arc size whether
In error range, used measurement method and principle are as follows:
One, it is horizontally arranged line measurement guide rail 1, is rotated to unclamp the second compressing member, the first measuring rod 3 and the are then slided
Then three measuring rods 5 are locked first and are surveyed so that the measurement end of the first measuring rod 3 and third measuring rod 5 is located in same level
The second compressing member on 5 place sliding block 2 of gauge rod 3 and third measuring rod makes the first measuring rod 3 and third measuring rod 5 be fixed on cunning
On block 2；The intersection point of first measuring rod 3 and sliding block 2 is set as E, the intersection point of third measuring rod 5 and sliding block 2 is set as F.
Two, the sliding block 2 slided where the first measuring rod 3 and third measuring rod 5 to unclamp the first compressing member is rotated, so that
Both ends of the measurement end of first measuring rod 3 and third measuring rod 5 respectively with arc structure 8 to be measured offset, and then lock the first pressure
Tight part；The abutment of first measuring rod 3 and circular arc is set as A, the abutment of third measuring rod 5 and circular arc is set as D, then first
It is M that measuring rod 3 and third measuring rod 5, which stretch out the length of sliding block 2, i.e. AE=DF=M.
Three, the correspondence scale of the first measuring rod 3 and third measuring rod 5 on line measurement guide rail 1 is read in peep hole,
The spacing L and midpoint scale between the first measuring rod 3 and third measuring rod 5 are calculated, and slides 4 place sliding block 2 of the second measuring rod,
So that the second measuring rod 4 reaches midpoint scale corresponding position, the first locking member on locking sliding block 2, by the second measuring rod 4 and sliding block
Intersection point between 2 is set as G, then
Four, the second measuring rod 4 of sliding makes the measurement end of low measuring rod offset with arc structure 8 to be measured, by circle to be measured
The point that arc structure 8 and the second measuring rod 4 offset is set as C, reads the length N that the second measuring rod 4 stretches out sliding block 2.
Five, the CG theoretical value for calculating the circular arc to be measured that radius is R, as shown in figure 3, the center of circle is set as O, because of OA=OC=
OD=R,
So
So BG=AE=M
So
So
Six, the error of circular arc to be measured, error=N-CG theoretical value of circular arc to be measured are calculated, whether error in judgement is providing
In range, illustrate that arc structure meets building standard if within the specified scope.
