Description
Technical Field
[0001] The present application relates to the technical field of building decoration, and more specifically, to a building inner corner structure. Background Art
[0002] Internal corners refer to the recessed corners on the wall of a building, also known as internal corners, such as the four corners in a room. In the related art, internal corner lines are generally used at the corners of the building wall to play a shaping role, and then plaster or putty is applied on the surface of the internal corner lines to ensure the integrity of the building wall. Usually, the internal corner lines are composed of accessories made of PVC material.
[0003] However, in actual use, the wall of the building will undergo a certain amount of shrinkage and deformation, which will cause the inner corner lines to be torn by the shrinkage and deformation of the building wall, thereby causing damage to the plastered or putty surface of the building wall. Utility Model Content
[0004] In view of this, an embodiment of the present application provides a building internal angle structure to solve the problem in the related art that the internal angle lines may be torn when the building wall is deformed.
[0005] In order to achieve the above objectives, the present application provides the following technical solutions:
[0006] A building inner corner structure, comprising:
[0007] A first internal angle strip, the first internal angle strip comprising a first side plate, a flange is provided at a position of the first side plate near an edge line in a length direction, a protrusion is provided beside the flange, and a groove is formed between the flange and the protrusion; the first side plate is used to be connected to a building fixing surface;
[0008] The second internal angle strip comprises a second side panel, a convex body used in conjunction with the groove is arranged at the edge line in the length direction of the second side panel, the convex body is located in the groove, the second internal angle strip is connected to the first internal angle strip; the second side panel is connected to the retractable surface of the building.
[0009] In some possible implementations, the first side plate and the second side plate are both provided with a plurality of ash sticking holes;
[0010] The first side plate is connected to the building fixing surface through the mortar sticking hole;
[0011] The second side plate is connected to the retractable surface of the building through the mortar sticking holes.
[0012] In some possible implementations, the plurality of ash-collecting holes of the first side plate include fully transparent ash-collecting holes and semi-transparent ash-collecting holes, and the plurality of ash-collecting holes of the second side plate are fully transparent ash-collecting holes.
[0013] In some possible implementations, the protrusion is vertically connected to the second side panel, and a cross-sectional shape formed by the protrusion and the second side panel is L-shaped.
[0014] In some possible implementations, the length of the flange is smaller than the length of the protrusion;
[0015] A notch is provided on the side of the convex body for use with the flange;
[0016] An interlocking structure is formed between the flange, the protrusion, the groove, the convex body and the notch.
[0017] In some possible implementations, the outer side surface of the protrusion is a chamfered surface.
[0018] The building internal angle structure provided by the embodiment of the present application has at least the following beneficial effects:
[0019] In the building internal angle structure provided in the embodiment of the present application, a groove is provided on the first side plate of the first internal angle strip, and the first internal angle strip is connected to the fixed surface of the building through the first side plate. In contrast, the second side plate of the second internal angle strip is provided with a convex body used in conjunction with the groove, the convex body is located in the groove of the first side plate, and the second side plate is connected to the retractable surface of the building. In this way, when the retractable surface of the building shrinks and deforms, the first internal angle strip will not move, and the second internal angle strip will move simultaneously with the retractable surface of the building, so that the convex body on the second side plate will partially slide out of the groove. At this time, the plastered surface or putty surface of the building will not produce visually unacceptable cracks, and only part of the structure of the second internal angle strip at the millimeter level will be exposed, thereby avoiding the problem that the first internal angle strip and the second internal angle strip will move in two directions under traditional circumstances, thereby causing cracks on the plastered surface or putty surface.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] Internal corners refer to the recessed corners on the wall of a building, also known as internal corners, such as the four corners in a room. In the related art, internal corner lines are generally used at the corners of the building wall to play a shaping role, and then plaster or putty is applied on the surface of the internal corner lines to ensure the integrity of the building wall. Usually, the internal corner lines are composed of accessories made of PVC material.
[0029] However, in actual use, the lightweight wall panels of the building will produce certain shrinkage deformations, which makes it impossible for the traditional L-shaped internal angle lines to coordinate these shrinkage deformations, thereby tearing the plastered or putty surfaces of the building.
[0030] like Figure 1-Figure 4As shown, an internal angle structure of a building provided by an embodiment of the present application includes a first internal angle strip 100 and a second internal angle strip 600. The internal angle structure of the building is composed of the first internal angle strip 100 and the second internal angle strip 600. The first internal angle strip 100 includes a first side panel 200, and the first side panel 200 includes an inner surface and an outer surface. The inner surface of the first side panel 200 is provided with a flange 300, and the flange 300 is arranged at the edge line of the length direction of the first side panel 200. The inner surface of the first side panel 200 is also provided with a protrusion 400, and the protrusion 400 is located beside the flange 300, and the protrusion 400 and the flange 300 form a groove 500. Preferably, the outer side surface of the protrusion 400 can be a chamfered surface 410.
[0031] In this embodiment, the outer surface of the first side plate 200 is fixedly connected to the fixed surface of the building, and the fixed surface of the building may be a concrete surface of a beam or a column, that is, the outer surface of the first side plate 200 is fixedly connected to the fixed surface of the building.
[0032] The second internal angle strip 600 includes a second side plate 700. Similarly, the second side plate 700 includes an inner surface and an outer surface. A convex body 800 is provided on the inner surface of the second side plate 700. The convex body 800 is provided at the edge line of the second side plate 700 in the length direction. Preferably, the convex body 800 and the second side plate 700 are perpendicular to each other, and the cross-sectional figure formed between the convex body 800 and the second side plate 700 is L-shaped. The convex body 800 is matched with the groove 500 on the first internal angle strip 100, and the second internal angle strip 600 is connected to the first internal angle strip 100.
[0033] Specifically, the outer surface of the second internal angle strip 600 is fixedly connected to the retractable surface of the building, and the retractable surface of the building can be a lightweight wall surface.
[0034] In actual use, Figure 3 As shown, the protrusion 400 of the second internal angle strip 600 is first embedded in the groove 500 of the first internal angle strip 100, so that the second internal angle strip 600 and the first internal angle strip 100 are combined into an L-shaped internal angle strip. In addition, the construction method of the L-shaped internal angle strip is consistent with the construction method of the traditional internal angle strip, and can also play the role of shaping the internal angle, so this embodiment will not be described in detail here.
[0035] In the internal angle structure of the building provided in the embodiment of the present application, the first side plate 200 of the first internal angle strip 100 is provided with a groove 500, and the first internal angle strip 100 is connected to the fixed surface of the building through the first side plate 200. In contrast, the second side plate 700 of the second internal angle strip 600 is provided with a convex body 800 used in conjunction with the groove 500, the convex body 800 is located in the groove 500 of the first side plate 200, and the second side plate 700 is connected to the retractable surface of the building. In this way, when the retractable surface of the building shrinks and deforms, the first internal angle strip 100 will not move, and the second internal angle strip 600 will move simultaneously with the retractable surface of the building. At this time, the plastered surface or putty surface of the building will not produce visually unacceptable cracks, and only the partial structure of the second internal angle strip 600 at the millimeter level will be exposed, thereby avoiding the problem that the first internal angle strip 100 and the second internal angle strip 600 will move in two directions of the L shape under traditional circumstances, thereby causing cracks on the plastered surface or putty surface.
[0036] In some embodiments, a plurality of mortar sticking holes 900 are provided on the first side plate 200 and the second side plate 700. Specifically, the first side plate 200 is connected to the fixed surface of the building through the mortar sticking holes 900, and the second side plate 700 is connected to the retractable surface of the building through the mortar sticking holes 900. Figure 1 and Figure 2 As shown, the mortar holes 900 on the first side plate 200 include some fully transparent mortar holes 900 and semi-transparent mortar holes 900, and the mortar holes 900 on the second side plate 700 are all fully transparent mortar holes 900. The mortar holes 900 can be used to fix the first internal angle strip 100 and the second internal angle strip 600 on the corresponding wall of the building to reduce the probability of them falling off.
[0037] In some embodiments, Figure 1 As shown, the length of the flange 300 on the first side plate 200 is less than the length of the protrusion 400. In contrast, the inner surface of the second side plate 700 is provided with a notch 810 used in conjunction with the flange 300. The notch 810 is located beside the protrusion 800. Figure 3 As shown, when the first internal corner strip 100 is connected to the second internal corner strip 600, an interlocking structure is formed between the flange 300, the protrusion 400, the groove 500, the protrusion 800 and the notch 810, which can prevent the first internal corner strip 100 and the second internal corner strip 600 from moving relative to each other in other directions during actual use, so as to damage the wall of the building.
