[0023] Combined with the accompanying drawings in the embodiments of the present invention below, the technical solutions in the embodiments of the present invention are clearly and completely described. Many specific details are set forth in the following description in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0024] As Figures 1-4 described, the present invention discloses a ruler for measuring the perpendicularity of beam-column formwork, which includes an upper ruler handle 1, a lower ruler handle 2, an upper scale 3, a lower scale 4 and a plumb bob 5. The upper ruler handle 1 and the lower ruler handle 2 are telescopically connected. As Figure 4 shown, as a way of telescopic connection, the upper ruler handle 1 is slidably inserted into the interior of the lower ruler handle 2. The upper ruler handle 1 is provided with a vertical slot 11. A block 12 is clamped in the slot 11. The bottom wall of the block 12 abuts against the bottom of the slot 11, and the side wall of the block 12 abuts against the side wall of the slot 11. One end of the block 12 away from the bottom of the slot is rotatably connected to a bolt 13, and the bolt 13 is threadedly connected to the side wall of the lower ruler handle 2. When in use, the upper ruler handle 1 is inserted into the lower ruler handle 2, and the exposed length of the upper ruler handle 1 is adjusted. When the length is appropriate, the bolt 13 is rotated, and the bolt 13 presses against the block 12, and the block 12 presses against the slot 11, so as to fix the exposed length of the upper ruler handle 1.

[0025] The lower scale 4 is vertically arranged with the lower ruler handle 2, and the lower scale 4 is telescopically arranged at the bottom of the lower ruler handle 2. As Figure 2 shown, as a way of telescopic connection, the lower scale 4 includes a knob 41, a gear 42, and a first scale 43. The knob 41 is arranged on the outside of the lower ruler handle 2. The rod body of the knob 41 passes through the side wall of the lower ruler handle 2 and enters the interior of the lower ruler handle 2. The rod body of the knob 41 is fixedly connected to the gear 42. When the knob 41 rotates, it can drive the gear 42 to rotate. The gear 42 is arranged inside the lower ruler handle 2. A toothed plate 44 is provided at the top of the first scale 43, and the toothed plate 44 meshes with the gear 42. The bottom of the first scale 43 abuts against the bottom wall of the lower ruler handle 2.

[0026] The upper scale 3 is perpendicularly arranged with the upper ruler handle 1, and the upper scale 3 is telescopically connected to the top of the upper ruler handle 1. As Figure 2 shown, as a way of telescopic connection, an installation cavity 14 for installing the upper scale 3 is opened at the top of the upper ruler handle 1. The upper scale 3 includes a handwheel 31, a lead screw 32 and a second scale 33. The handwheel 31 is located outside the installation cavity 14. The handwheel 31 is fixedly connected to one end of the lead screw 32. The lead screw 32 passes through the side wall of the installation cavity 14. The lead screw 32 is threadedly connected to the side wall of the installation cavity 14. The other end of the lead screw 32 is rotatably connected to the second scale 33.

[0027] In order to ensure that the upper ruler handle 1 and the lower ruler handle 2 are in a vertical state during use, a plumb bob 5 is also fixedly connected to the outer wall of the upper ruler handle 1. As Figure 1 shown, the plumb line edge of the plumb bob 5 coincides as much as possible with the boundary line between the upper scale 3 and the upper ruler handle 1.

[0028] In order to ensure that the ruler is in a horizontal state during the measurement of perpendicularity, a level bubble 6 is fixedly connected to the bottom of the outer wall of the lower ruler handle 2. When the level bubble 6 is placed horizontally, the lower ruler handle 2 is in a vertical state.

[0029] During use, first insert the upper ruler handle 1 into the lower ruler handle 2, and then adjust the knob 41 to make the lengths of the upper ruler handle 1 and the lower ruler handle 2 adapt to the requirements of the measurement space. Rotate the handwheel 31 to adjust the exposed length of the second scale 33. For example, the external length of the second scale 33 can be 200 mm. Then, vertically press the upper scale 3 against the upper part of the beam-column formwork. Ensure that the lower ruler handle 2 is vertical and horizontally level through the plumb bob 5 and the level bubble 6. Finally, adjust the knob 41 to adjust the exposed length of the first scale 43 so that the first scale 43 abuts against the lower part of the beam-column formwork, record the length of the first scale 43, and the perpendicularity of the beam-column formwork can be calculated.

[0030] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
