Specific embodiment

Referring to Fig. 1 to Fig. 6, a kind of beam body detection instrument ruler of bridge, including main scale 1, auxiliary scale 2, the main scale 1 are equipped with One sliding slot 1a, sliding slot 1a are slidably matched with main scale extended segment 1b.It further include main scale slide 3, auxiliary scale slide 4, the main scale is sliding Seat 3 is equipped with protractor 3a, and the upper surface of the main scale slide 3 is equipped with an internal screw thread boss 3b, which is located at amount The lower end surface at the center of angle device 3a, main scale slide 3 is equipped with a main scale sliding slot 3c, the extending direction and protractor of main scale sliding slot 3c The zero graduation line of 3a is parallel, and the main scale 1 is slidably fitted in main scale sliding slot 3c, and the side cell wall of the main scale sliding slot 3c is equipped with Locking bolt 3d is equipped with an auxiliary scale sliding slot 4a for locking 1 position of main scale, the upper surface of the auxiliary scale slide 4, and the auxiliary scale is sliding The lower end surface of seat 4 is equipped with the hole post 4b extended downwardly, and auxiliary scale slide 4 is run through in the hole of hole post 4b, and the hole post 4b is fixed side Extend auxiliary scale slide 4, the extending direction and auxiliary scale sliding slot of angle indicator 4c equipped with angle indicator a 4c, the angle indicator 4c The extending direction of 4a is identical, and the auxiliary scale 2 is slidably fitted in auxiliary scale sliding slot 4a, and it is long to be equipped with one along its length in the auxiliary scale 2 Hole 2a, a flanged clamping screw 4e sequentially pass through the strip hole 2a of auxiliary scale 2, the hole post 4b of auxiliary scale slide 4 and main scale is sliding The internal screw thread boss 3b of seat 3 is threadedly engaged fixation, auxiliary scale slide 4 is connected and fixed with main scale slide 3 and forms auxiliary scale 2 positions.

As shown in fig. 6, first main scale 1 is fastened on main scale slide 3 with locking bolt 3d, makes the length of main scale 1 when measurement The thickness of surveyed 5 side wall FB of beam body can be measured, then auxiliary scale 2 is pushed to slide along auxiliary scale slide 4, with the zero graduation of auxiliary scale 2 End resists the angular vertex A of the inner corner trim ∠ EAB of surveyed beam body 5, and it is sliding whether the angle indicator 4c on observation auxiliary scale slide 4 is directed at main scale 90 ° of positions of protractor 3a on seat 3, if alignment, means that surveyed 5 side wall FB of beam body and horizontal vertical, otherwise surveyed beam body 5 Side wall FB and horizontal out of plumb can read the 5 side wall FB error of perpendicularity of beam body from protractor 3a.If the angle on auxiliary scale slide 4 90 ° of positions for spending protractor 3a on pointer 4c alignment main scale slide 3, then show main scale 1 and auxiliary scale 2 is to be mutually perpendicular to state, twists Tight clamping screw 4e fastens auxiliary scale slide 4 and main scale slide 3, makes to keep plumbness between main scale 1 and auxiliary scale 2.Then from pair The length l that angular vertex A of the clamping screw 4e axle center C point away from inner corner trim ∠ EAB is read on ruler 2, reads clamping screw 4e from main scale 1 Height h of the C point in axle center away from surveyed 5 side wall B point of beam body, make this beam body detection instrument ruler and surveyed beam body 5 inner corner trim bevel edge AB it Between formed right angled triangle △ BAC.

In the state that main scale 1 and the holding of auxiliary scale 2 are mutually perpendicular to, the yin of surveyed beam body 5 is resisted with the zero mark end of main scale 1 The angular vertex A of angle ∠ EAB, makes main scale 1 and horizontal vertical, then clamping screw 4e axle center D point is read from main scale 1 away from inner corner trim ∠ The height h ' of the angular vertex A of EAB reads length of the clamping screw 4e axle center D point away from surveyed 5 side wall E point of beam body from auxiliary scale 2 L ' makes to form right angled triangle △ EAD between this beam body detection instrument ruler and the inner corner trim bevel edge AE of surveyed beam body 5.

If in the measurements, 1 length of main scale is inadequate, it can suitably extend outwardly and preside over extended segment 1b, then be read.

When calculating 5 obtuse angle inner corner trim ∠ EAB angle of beam body, since the angle of obtuse angle inner corner trim ∠ EAB is acute angle ∠ CAB's Degree adds the degree of acute angle ∠ EAD, and along with the degree of a right angle ∠ DAC, and the degree of acute angle ∠ CAB is y= Arctan (h/l), wherein y ∈ (- pi/2, pi/2), and the degree of acute angle ∠ EAD is y=arctan (h '/l '), wherein y ∈ (- π/ 2, pi/2), therefore, the degree of inner corner trim ∠ EAB is+90 ° of y=arctan (h/l)+arctan (h '/l '), wherein y ∈ (90 ° of-π, 90 ° +π)。

As shown in Figure 6 and Figure 7, when measuring the angle of 5 external corner 6 of beam body, main scale 1 is first fastened on main scale with locking bolt 3d On slide 3, main scale 1 is abutted into 5 side wall bevel edge 6a of beam body, guarantees that main scale 1 is parallel with side wall bevel edge 6a, rotates auxiliary scale 2, make auxiliary scale 2 abut 5 bottom edge 6b of beam body, guarantee that auxiliary scale 2 is parallel with 5 bottom edge 6b of beam body, then tighten clamping screw 4e for auxiliary scale slide 4 and main scale Slide 3 fastens, and makes to keep the state between main scale 1 and auxiliary scale 2.At this point, the angle indicator 4c on observation auxiliary scale slide 4 is directed at master The angle position of protractor 3a on ruler slide 3, the angle degree of reading are the angle of 5 external corner 6 of beam body.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, it is clear that this field Technical staff various modification and variations can be carried out to the utility model without departing from the spirit and scope of the utility model.This Sample, if these modifications and variations of the present invention belong to the claims of the present invention and its equivalent technology range it Interior, then the utility model is also intended to include these modifications and variations.
