Problems solved by technology

With the rapid development of modern decoration engineering technology, this method has exposed many shortcomings in use, such as slow corner cutting speed, low efficiency, and easy damage to the board if you are not careful. The damage of the corner of the sun makes the newly decorated wall a fly in the ointment due to the damage of the corner of the wall

Embodiment 1

[0030] like image 3 As shown, the cross-sectional shape composed of the male corner face 2 and the female corner face 3 is a cross-sectional shape surrounded by the periphery after overlapping a quadrilateral on the male corner face 2 and a rhombus on the female corner face 3, Wherein, the two connecting sides 21 and 22 are equal, and the angle bisector 7 of the included angle α partially overlaps with a diagonal line 8 on the rhombus near the apex of the included angle α.

Embodiment 2

[0032] like Figure 4 As shown, the cross-sectional shape composed of the male corner face 2 and the female corner face 3 is a cross-sectional shape surrounded by the periphery after overlapping a quadrilateral on the male corner face 2 and a rhombus on the female corner face 3, Protrusions 9 running along the wall surface are provided on the quadrangle at the two end points of the other two sides opposite to the angle α that do not intersect.

Embodiment 3

[0034] like Figure 5 As shown, the cross-sectional shape composed of the male corner face 2 and the female corner face 3 is a cross-sectional shape surrounded by the periphery after overlapping a quadrilateral on the male corner face 2 and a rhombus on the female corner face 3 , the quadrilateral is provided with a tenon 10 or a groove 11 on the two equal connecting sides 21, 22 respectively, and its shape corresponds to the shape of the side 41 at one end of the decorative panel 4 at the corner joint. .

Abstract

The invention discloses a corner lock for decoration engineering, and aims to solve technical problems on the connection of decoration panels at corner joints between decorated wall surfaces in interior decoration engineering. The technical scheme is that: the corner lock for the decoration engineering is an elongated profile, has a consistent sectional shape, consists of an external corner surface and an internal corner surface, and is arranged at a corner between the decorated wall surfaces. Two connection edges are formed on the external corner surface, and are connected with a side edge at one end of a decoration panel at the corner joint between the decorated wall surfaces respectively. The shortest connecting line between the two connection edges is a dividing line of the external corner surface and the internal corner surface. The projection of at least one of all line segments parallel to the connecting line on the internal corner surface on the connecting line completely covers the connecting line, and has a length greater than that of the connecting line. The corner lock for the decoration engineering is convenient to arrange and can be made from various materials so as to be rich in color, varied in shape and attractive in appearance; and a decorated wall surface corner is difficult to damage.

Description

technical field [0001] The invention relates to a component for interior decoration, in particular to a structural component used for connecting wall surfaces at indoor corners. Background technique [0002] At present, in the interior wall decoration panel decoration project, the industry still uses the traditional method to deal with the problem of how to deal with the corner joints of the two walls. The corners formed by splicing the decorative panels at the corner joints are commonly used in engineering terms. Indicated by the negative angle, the part facing the room that people can directly observe is called the positive corner, and the part facing the corner wall that is covered by the decorative panel is called the negative corner. Edge masking, or according to the angle of the required angle of the wall panels, cut the sides of the panels next to the two walls at the connection to one-half of the required corner angle, and then splice the two panels, For wood veneer...
