Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a stair plastering step corner protection device. Background Art

[0002] Traditional plastering step corner protection strips only have a "┏"-shaped cross-section strip body, the inner side of the strip body is smooth and has holes. This type of corner protection strip has the following defects:

[0003] First, the inner side of the corner guard is smooth, and the bonding with the step mortar is not strong enough, which can easily cause the corner guard to fall off; second, the wingspan of the corner guard is small, and the verticality and flatness of the step edges and corners are poor; third, the corner guard is in the shape of a 90° angle, which makes it impossible for the edge of the corner guard to be seamlessly connected to the step surface; fourth, the firmness and impact resistance of the right-angle part are poor, and the edges of the corner guard are easily deformed under uneven loads or shear forces, causing the cement mortar to crack and fall off.

[0004] In order to solve the above problems, we proposed a stair plastering step corner protection device. Utility Model Content

[0009] In the above-mentioned stair plastering step corner protection device, the outer wall of the first side panel is provided with a plurality of first slots, and the outer wall of the second side panel is provided with a plurality of second slots, the first slots penetrate the front and rear side walls of the first side panel, and the second slots penetrate the front and rear side walls of the second side panel.

[0010] In the above-mentioned stair plastering step corner protection device, the angle between the first side plate and the second side plate is an acute angle.

[0011] In the above-mentioned stair plastering step corner protection device, the corner protection nose is elastic.

[0012] Compared with the existing technology, the advantages of this stair plastering step corner protection device are:

[0013] During the plastering construction, the utility model places the corner protection device at the edge of the step, and uses the first anti-skid nails in the first anti-skid net wing and the second anti-skid nails in the second net wing to embed into the mortar layer for fixation, thereby reinforcing the edge of the step, and effectively bearing and transmitting the uneven load or shear force applied to the step, thereby ensuring the aesthetics of the plastered step surface.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 5 A stair plastering step corner protection device comprises a corner protection nose 1, the corner protection nose 1 is arranged in a long strip shape, and the cross section of the corner protection nose 1 is arranged in an arc shape, the corner protection nose 1 is elastic, the upper end of the corner protection nose 1 is fixedly connected with a first side plate 2 arranged obliquely, and the lower end of the corner protection nose 1 is fixedly connected with a second side plate 3 arranged obliquely, the first side plate 2 and the second side plate 3 are arranged symmetrically about the corner protection nose 1, the angle between the first side plate 2 and the second side plate 3 is an acute angle, which is arranged at 70 degrees, and the right side of the first side plate 2 A first anti-skid net wing 4 is fixedly connected to the end, and the first anti-skid net wing 4 is coplanar with the outer wall of the first side plate 2. A second anti-skid net wing 5 is fixedly connected to the right end of the second side plate 3, and the second anti-skid net wing 5 is coplanar with the outer wall of the second side plate 3. Anti-skid nails 6 are fixedly arranged on each intersection of the first anti-skid net wing 4, and the anti-skid nails 6 are perpendicular to the inner side wall of the first anti-skid net wing 4 and downward. Anti-skid nails 7 are fixedly arranged on each intersection of the second anti-skid net wing 5, and the anti-skid nails 7 are perpendicular to the inner side wall of the second anti-skid net wing 5 and upward.

[0022] The right end of the first anti-skid net wing 4 is fixedly connected to the first side plate 8, and the right end of the second anti-skid net wing 5 is fixedly connected to the second side plate 10. The outer side walls of the first side plate 8 and the second side plate 10 are respectively provided with a first inclined surface 9 and a second inclined surface 11. The first inclined surface 9 and the second inclined surface 11 make the first anti-skid net wing 4 and the second anti-skid net wing 5 transitionally connected to the surface of the stair treads after mortar is applied, so that the corner protection device is higher than the outer wall of the stair tread, and the height of the higher height is the thickness of the first side plate 2, so that pedestrians can first touch the corner protection device so that the corner protection device can provide protection for the stair treads.

[0023] The outer wall of the corner guard nose 1 is provided with a plurality of overflow slots 12, which penetrate the corner guard nose 1 and are arranged at equal intervals along the long side line of the corner guard nose 1. The outer wall of the first side panel 2 is provided with a plurality of first slots 13, and the outer wall of the second side panel 3 is provided with a plurality of second slots 14. The first slots 13 penetrate the front and rear side walls of the first side panel 2, and the second slots 14 penetrate the front and rear side walls of the second side panel 3. The first slots 13 and the second slots 14 respectively increase the roughness of the outer walls of the first side panel 2 and the second side panel 3, which is beneficial to increase the friction between the corner guard device and the sole of the pedestrian's shoe, and improve the stability of the pedestrian when stepping on the stairs.

[0024] Apply a proper amount of cement mortar evenly on the stair tread surface, fit the corner guard nose 1 with the edge of the stair tread corner, attach the first side plate 2 and the first anti-skid mesh wing 4 to the horizontal surface of the tread, attach the second side plate 3 and the second anti-skid mesh wing 5 to the vertical surface of the tread, and gently tap the corner guard nose 1 along the length of the stair tread corner guard in sequence to make the cement mortar applied on the stair tread surface overflow from the holes of the first anti-skid mesh wing 4 and the second anti-skid mesh wing 5, and at the same time make the mortar overflow from the overflow groove 12. After the mortar solidifies, the mortar in the overflow groove 12 will limit the corner guard nose 1 in the horizontal direction, further improving the corner guard. The stability of the nose 1 is ensured, and the anti-skid studs 1 6 and 2 7 are allowed to penetrate into the mortar layer. A proper amount of cement mortar is applied on the stair tread surface. The thickness of the applied cement mortar exceeds the thickness of the first side plate 2. A level ruler is used to adjust the flatness of the tread surface. Due to the use of the first anti-skid mesh wing 4 and the second anti-skid mesh wing 5, the corner guard nose 1 and the first side plate 2, the second side plate 3 will not fall off from the corners of the tread due to insufficient bonding between the first side plate 2, the second side plate 3 and the tread. At the same time, it effectively bears and transmits the uneven load or shear force applied to the tread, thereby ensuring the aesthetics of the plastered tread surface.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
