[0005] Further, the first stepped narrow strip groove is formed on the outer surface of the vertical plate and the horizontal plate, and the second stepped narrow strip groove is formed on the inner surface of the vertical plate and the horizontal plate.
[0006] Further, a plurality of hollow grooves are formed at equal intervals in the vertical plate and the horizontal plate, and the hollow grooves are one of a circle and an ellipse.
[0007] Further, the vertical plate and the horizontal plate are embedded with a clamping strip for plugging the first stepped narrow strip groove, and the clamping strip is in interference embedding cooperation with the first stepped narrow strip groove.
[0008] Further, a plurality of conical convex points are integrally formed on the outer surface of the vertical plate and the horizontal plate.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] The technical solution of this application uses a right-angle plate with a narrow groove to install the right-angle plate at the external corner with expansion screws, which facilitates manual intervention to create an external corner with a high right angle. By setting a stepped narrow groove, the narrow groove can be sealed after the expansion screws are installed, so as to avoid rust spots on the exterior surface caused by the corrosion of the expansion screws later. The right-angle plate has a hollow groove, which reduces the weight of the material and thus reduces the cost. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Example 1, such as Figs. 1-2 As shown, this utility model provides a technical solution: a straightening device for the external corner of a building, including a right-angle plate 1. The right-angle plate 1 includes a vertical plate 101 and a horizontal plate 102 arranged perpendicularly to each other. The vertical plate 101 and the horizontal plate 102 are each provided with a plurality of stepped grooves at equal intervals. The stepped grooves include a first stepped narrow strip groove 201 and a second stepped narrow strip groove 2. The width of the narrow side of the first stepped narrow strip groove 201 is 8mm larger than the width of the second stepped narrow strip groove 2. An expansion screw 3 for fixing the right-angle plate 1 is embedded inside the second stepped narrow strip groove 2.
[0017] In one specific embodiment of the utility model, the right angle plate 1 adopts polyurethane material plate, is used for preventing rust point problem brought by rust, the right angle plate 1 is attached with the external corner, the drop point of expansion screw 3 is marked at the external corner, then drilling is carried out at the mark point, the right angle plate 1 is attached to the external corner again, expansion screw 3 is connected with the expansion sleeve in the hole through the second ladder narrow strip groove 2, the nut of expansion screw 3 is clamped between the second ladder narrow strip groove 2 and the first ladder narrow strip groove 201, the clamping strip 6 is pressed into the inside of the first ladder narrow strip groove 201, at this time the nut of expansion screw 3 is shielded and the ladder narrow strip groove is shielded as a whole, can be directly carried out on the surface of right angle plate 1 putty and paint brushing, since the right angle plate 1 replaces the building external corner, the right angle plate 1 with high right angle is used as the external corner, realizes the effect of finding straight of external corner.
