Description

Technical Field

[0001] This utility model relates to the field of building construction materials technology, and specifically refers to a new type of external corner strip. Background Technology

[0002] In construction projects, the outer corners (external corners) of walls often suffer from quality problems such as missing corners, bulging, or cracks due to collisions or construction errors. Traditional external corner strips are mostly made of metal, which has a certain degree of impact resistance, but also suffers from defects such as rusting, complex construction, and difficulty in shaping.

[0003] In recent years, plastic corner strips have been gradually used to replace metal corner protectors, but existing plastic corner strips still generally have the following problems: lack of construction assistance design, low installation efficiency; non-degradable materials, poor environmental performance; easy aging and deformation, poor durability. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a new type of external corner strip, which solves the problems of existing external corner strips lacking construction assistance design after use, having low installation efficiency, and using non-degradable materials with poor durability.

[0005] The technical solution to achieve the above objectives is:

[0006] This utility model provides a novel external corner strip for corner protection, the external corner strip comprising:

[0007] Two wing-plate structures are attached to the corner of the inner wall and embedded in the plaster layer, with the angle between the two wing-plate structures being less than 90°.

[0008] Corner guard strips are installed along the entire outer length of the joint between the two wing plate structures and embedded in the plaster layer. The angle between the corner guard strips and the two wing plate structures is equal.

[0009] The anti-collision strip is installed along the outer end of the corner guard strip and at the corner of the outer side of the plaster layer.

[0010] Furthermore, it also includes at least three reinforcing ribs, one of which is vertically embedded at the connection between the two wing plate structures, and the other two are vertically embedded at the corresponding ends of the corresponding wing plate structures.

[0011] Furthermore, both wing plates have multiple through holes.

[0012] Furthermore, it also includes two first pressure strips and two second pressure strips. The two first pressure strips are respectively fixed to the top and bottom of one of the wing plate structures, and the two second pressure strips are respectively fixed to the top and bottom of the other wing plate structure.

[0013] Furthermore, the outer surfaces of the two wing plate structures are provided with multiple vertical strips, which are spaced apart.

[0014] Furthermore, the two wing plate structures, the corner guard strips, and the anti-collision strips are all made of plastic.

[0015] Furthermore, the cross-section of the anti-collision strip is semi-circular, and the arc-shaped surface of the anti-collision strip is located on the outer side, while the flat surface is located on the inner side and is fixedly connected to the corner guard strip.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By using two wing-plate structures with an included angle of less than 90°, the wing-plate structure is placed more tightly against the inner wall 7 at its corner. Corner guards and anti-collision strips are also installed at the connection point of the two wing-plate structures to protect the corner. Embedding the wing-plate structure within the plaster layer enhances the aesthetics of the constructed wall. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] See Figure 1 This utility model provides a novel external corner strip, solving the problems of existing external corner strips, such as lack of construction assistance design, low installation efficiency, and the use of non-degradable and undurable materials. By setting two wing plate structures with an included angle of less than 90° between them, the wing plate structures are more tightly fitted to the corner of the inner wall 7. Corner guard strips and anti-collision strips are also installed at the connection point of the two wing plate structures to protect the corner. By embedding the wing plate structure within the plaster layer, the constructed wall is more aesthetically pleasing.

[0024] The following description, in conjunction with the accompanying drawings, illustrates a novel external corner strip of this utility model.

[0025] See Figure 1 This diagram illustrates the effect of using a novel external corner strip according to this utility model. (See attached image.) Figure 2 The diagram shows a structural schematic of one embodiment of a novel external corner strip according to this utility model. The following is in conjunction with... Figure 1 and Figure 2 This invention provides a description of a novel external corner strip.

[0026] like Figure 1 and Figure 2 As shown, this utility model discloses a novel external corner strip for corner protection, characterized in that: the external corner strip includes: two wing plate structures, which are closely attached to the corner of the inner wall 7 and embedded in the plaster layer 8, with the angle between the two wing plate structures being less than 90°; a corner guard strip 4, which is set along the outer side of the connection between the two wing plate structures and embedded in the plaster layer 8, with the angle between the corner guard strip 4 and the two wing plate structures being equal; and an anti-collision strip 5, which is set along the outer end of the corner guard strip 4 and is located at the corner of the outer side of the plaster layer 8.

[0027] Specifically, the angle between the two wing plate structures is between 85° and 90°. By making the angle between the two wing plate structures less than 90°, when the two wing plate structures are installed on the inner wall 7, the included angle can be changed to 90° through slight deformation. This allows the two wing plate structures to be tightly attached to the inner wall 7, which facilitates installation and prevents the wing plate structures from warping and making it difficult to carry out the next step of construction.

[0028] In a preferred embodiment, the angle between the two wing plate structures is 88°.

[0029] In one specific embodiment, it also includes at least three reinforcing ribs 1, one of which is vertically embedded at the connection between the two wing plate structures, and the other two reinforcing ribs 1 are vertically embedded at the corresponding end of the corresponding wing plate structure.

[0030] Specifically, the other two reinforcing ribs 1 are vertically embedded at the ends of the two wing structures that are far apart from each other.

[0031] In one specific embodiment, multiple through holes 6 are provided on both wing plate structures. By providing through holes 6 on the wing plate structures, the plaster layer 8 can directly contact the inner wall 7 through the wing plate structure during construction, thereby preventing the plaster layer 8 from falling off due to an excessively large wing plate structure area causing weak adhesion between the plaster layer 8 and the inner wall 7.

[0032] In a preferred embodiment, the through hole 6 is circular or semi-circular. The diameter of the through hole 6 is 4-8 mm, and the spacing between adjacent through holes 6 is 20-40 mm.

[0033] In one specific embodiment, it also includes two first pressure strips 3 and two second pressure strips 9. The two first pressure strips 3 are respectively fixed to the top and bottom of one of the wing plate structures, and the two second pressure strips 9 are respectively fixed to the top and bottom of the other wing plate structure.

[0034] In one specific embodiment, the outer surfaces of the two wing plate structures are provided with a plurality of vertical strips 2, which are spaced apart.

[0035] Specifically, the width of vertical strip 2 is 1-2mm, the spacing between adjacent vertical strips 2 is 2-4mm, and the height of vertical strip 2 is 0.2-0.5mm.

[0036] In a preferred embodiment, the two wing plate structures, the corner guard strips 4, and the anti-collision strips 5 are all made of plastic.

[0037] Ideally, the plastic material used should be recycled plastic.

[0038] In another preferred embodiment, the two wing plate structures, the corner guard strips 4, and the anti-collision strips 5 are all made of rubber.

[0039] In one specific embodiment, the cross-section of the anti-collision strip 5 is semi-circular, and the arc-shaped surface of the anti-collision strip 5 is located on the outer side, the flat surface is located on the inner side, and it is fixedly connected to the corner guard strip 4.

[0040] In a preferred embodiment, one wing structure has a length of 14 mm, and the other wing structure has a length of 21 mm. The corner guard strip 4 has a length of 10 mm, and the cross-sectional radius of the anti-collision strip 5 is 4 mm.

[0041] In another preferred embodiment, one wing structure has a length of 15mm, and the other wing structure has a length of 25mm. The corner guard strip 4 has a length of 5mm, and the cross-sectional radius of the anti-collision strip 5 is 3mm.

[0042] The following is a detailed description of the usage process of this novel external corner strip.

[0043] Cut the corner strip to the desired height based on the height of the interior wall 7.

[0044] Then, the corner strip is tightly attached to the corner of the inner wall 7, so that the two wing plate structures are tightly attached to the inner wall 7 on the corresponding side.

[0045] Then, apply a plaster layer 8 to the inner wall 7, so that the wing plate structure and corner guard strip 4 are embedded in the plaster layer 8, and the anti-collision strip 5 is exposed and located at the corner of the wall, so that the anti-collision strip 5 protects the corner of the wall.

[0046] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
