Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, in particular to a negative angle line. Background Art

[0002] The internal corner line is a decorative finishing line at the junction of two walls. It is usually used as a transition line between the vertical wall decoration and the ceiling decoration. It has both aesthetic and protective functions.

[0003] For newly built buildings, when the internal corner lines are installed, the moisture of the wall and ceiling materials is not completely discharged, and the moisture and water vapor inside and outside the building penetrate and accumulate. Especially in the hot and humid weather in the south, the internal space covered by the internal corner lines and the walls and ceilings is in a damp state for a long time. Some internal corner lines contain metal plates such as aluminum and stainless steel. They are in a high-humidity environment for a long time. Combined with the reaction of water and oxygen in the air, the surface will gradually oxidize and needle-shaped black spots will appear. The water contains oxygen, carbon dioxide and other gases and impurities, which will cause the metal plate to produce an ohmic potential difference, accelerate electrochemical corrosion, cause the plate to deform, and affect the aesthetics of the internal corner line.

[0026] The utility model provides a internal corner line 100, comprising a line body 10 and two water-absorbing layers 20, wherein the line body 10 has two installation surfaces 102 at an angle, and the two installation surfaces 102 are respectively used to be positioned relative to two wall surfaces of the internal corner of a building; each of the water-absorbing layers 20 is connected between each of the installation surfaces 102 and each of the wall surfaces, and the line body 10 is sealed and connected to the wall surface at a free end away from each of the installation surfaces 102.

[0027] The water-absorbing layer 20 is used to absorb liquid water or gaseous water. In some embodiments of the utility model, the water-absorbing layer 20 is made of paper, textiles or non-woven fabrics. The water-absorbing layer 20 can be mixed with a highly absorbent resin water-absorbing agent, which is a low-crosslinked hydrophilic polymer compound with a loose network structure. The molecule contains a large number of hydrophilic groups and has a large number of strong water-absorbing groups. It has a strong water-absorbing ability and a fast water-absorbing and water-releasing speed. When the wall 201 and the surrounding environment are humid or even have moisture, it can quickly absorb moisture, humidity and moisture; when the wall 201 and the surrounding environment are too dry, it slowly releases moisture to the outside, thereby maintaining the humidity balance of the space behind the inner corner line 100 and preventing the inner corner line 100 from deforming.

[0028] Considering that the material of the water absorbing layer 20 is generally flexible, if the water absorbing layer 20 is designed to be too thick, it is easy to cause the inner corner line 100 to loosen, and if the water absorbing layer 20 is designed to be too thin, the water absorbing performance cannot be guaranteed and it is easy to be saturated with water. Therefore, in some embodiments of the utility model, the thickness of the water absorbing layer 20 is greater than or equal to 1 mm and less than or equal to 5 mm. Specifically, it can be 1 mm, 2 mm, 3 mm, 5 mm, etc.; it is set according to the specific situation.

[0029] The water absorbing layer 20 may be connected to the wall by bonding or anchoring. The water absorbing layer 20 may also be connected to the wire body 10 by bonding or anchoring, which is not limited here.

[0030] The wire body 10 is generally a profile made of highly elastic and deformation-resistant metal materials such as aluminum, stainless steel, galvanized steel, copper, and plastic, and its thickness is generally set to 0.2mm to 2mm, and can specifically be 0.2mm, 0.5mm, 1mm, 2mm, etc.; it is set according to specific circumstances.

[0031] In the technical solution of the utility model, the wire body 10 of the internal corner line 100 has two sealing edges 101 and two installation surfaces 102. The two installation surfaces 102 are respectively opposite to the two walls of the internal corner of the building, and the two sealing edges 101 are respectively located on the outside of the two installation surfaces 102; the water absorption layer 20 is connected between the two installation surfaces 102 and the two walls of the internal corner; the sealing structure 30 is used to seal the sealing edge 101 and the wall 201 of the building. Through the above solution, the moisture in the internal corner of the building and the water vapor accumulated on the outside of the wall 201 can be absorbed by the water absorption layer 20, so that the internal corner line 100 is always in a dry environment, greatly slowing down the corrosion rate, thereby ensuring that the internal corner line 100 does not deform for a long time, and effectively maintaining the aesthetics of the internal corner line 100.

The wire body 10 is divided into the anchor 11 and the exterior decoration 13, which is convenient for assembly. The anchor 11 and the waterproof layer are first anchored to the wall 201, and then the exterior decoration 13 is installed on the anchor 11, which has good stability, no fixed structure is exposed on the outside of the exterior decoration 13, and good aesthetics.

[0033] Further, in some embodiments of the utility model, the inner corner line 100 also includes a sealing structure 30, and the sealing structure 30 includes a positioning strip 31 and a sealant 32. The positioning strip 31 is arranged between the sealing edge 101 and the wall 201, and the sealant 32 seals and connects the sealing edge 101, the positioning strip 31 and the wall 201. With such a configuration, when the sealant is applied and sealed, the sealant 32 is easy to adhere to the outer wall of the positioning strip 31, thereby preventing the sealant 32 from flowing under the action of gravity, and the sealing effect is good. The sealant 32 can be made of polyether sealant 32, silicone sealant 32, polysulfide sealant 32, glass sealant 32, etc. The positioning strip 31 can be made of expandable polyethylene material, which can also play a flame retardant effect.

[0034] In some embodiments of the utility model, the anchor 11 is provided with mounting holes 111 on the two mounting surfaces 102, respectively, and the screw 14 is installed in the mounting holes 111 and passes through the water absorbing layer 20 to be anchored to the wall 201. In this way, the anchor 11 and the water absorbing layer 20 are both fixed to the wall 201, which is convenient to install and has high structural reliability.

With such a configuration, the water absorbing layer 20 with size or assembly errors can be fine-tuned during installation, so that part of the water absorbing layer 20 can be redundant in the gap between it and the connecting plate 12, which is convenient for installation.

[0036] The connection plate and the exterior trim 13 can be connected in various specific ways, such as by snap-on, plug-in, etc. In some embodiments of the present invention, the surface of the connection plate facing the exterior trim 13 is connected with a connection arm 122, the exterior trim 13 includes an exterior trim panel 131 and a docking arm 132, the docking arm 132 is connected to the inner side of the exterior trim panel 131, the docking arm 132 is snap-on with the connection arm 122, and the sealing edge 101 is located at both sides of the exterior trim panel 131. With such a configuration, the structure is simple and easy to process and form, and the snap-on stability is good.

[0037] Furthermore, in some embodiments of the present invention, two connecting arms 122 and two docking arms 132 are provided, and the opposite sides of the two connecting arms 122 are respectively provided with a recess 123, and the opposite sides of the two docking arms 132 are respectively provided with a convex portion 133, and the two docking arms 132 are clamped on the outsides of the two connecting arms 122, and the convex portion 133 is engaged in the recess 123. In this way, the connection stability between the connecting plate and the exterior decoration 13 is further improved.

[0038] In some embodiments of the present invention, the two opposite sides of the outer decorative plate 131 are bent inwardly into a U shape to form the sealing edge 101. In this way, the two opposite sides of the outer decorative plate can produce a slight deformation to cope with assembly errors, which is conducive to improving the sealing between the outer decorative plate and the wall.
