[0026] For some existing corner decoration products, manual milling or bending operations are required on the construction site to ensure the smooth installation of the product, which is quite difficult and labor-intensive.
[0027] In view of the above issues, please see Figures 1 to 5 In some embodiments of this utility model, a corner decorative strip installation structure is provided, which includes an assembled wall panel 1 and a corner decorative strip 2. The assembled wall panel 1 is fixedly connected to the two side walls 3 of the corner. The corner decorative strip 2 is assembled and connected to the assembled wall panel 1 on the two side walls 3 respectively. The inner side 23 of the corner decorative strip 2 is spaced apart from or in contact with the corner.
[0028] An external corner refers to the external angle formed at the junction of two protruding wall surfaces 3. The external corner itself is part of the wall structure. In this embodiment, the external corner decorative strip 2 is a decorative and protective material, specifically used to cover, protect, or beautify the edge of the external corner of the wall, making the external corner smoother, stronger, and more beautiful, while preventing damage to the external corner.
[0029] Specifically, assembly connection refers to combining the prefabricated wall panel 1 and the external corner decorative strip 2 into a whole through a connection method, ensuring that the position and structural strength between the prefabricated wall panel 1 and the external corner decorative strip 2 meet the preset requirements. In this embodiment, both the prefabricated wall panel 1 and the external corner decorative strip 2 are prefabricated standard parts. During installation, only the external corner decorative strip 2 needs to be assembled and connected to the prefabricated wall panel 1. No secondary processing of the external corner decorative strip 2 is required. This not only makes the installation method uniform but also convenient.
[0030] Specifically, the corner trim 2 has an inner surface 23 and an outer surface 22. When installing the corner trim 2, the side facing the wall 3 is the inner surface 23, and the exposed side is the outer surface 22. In this embodiment, the inner surface 23 of the corner trim installed at the corner is either spaced from or in contact with the corner. If it is spaced from the corner, the inner surface 23 of the corner trim does not contact the corner or the walls 3 on both sides of the corner; if it is in contact with the corner, the inner surface 23 of the corner trim can contact part or all of the corner, but not the walls 3 on both sides of the corner, that is, it only contacts the corner. This achieves the effect that the inner surface 23 of the corner trim does not interfere with the corner, making the installation of the corner trim 2 more convenient.
[0031] The corner decorative strip installation structure provided in this embodiment is fixedly connected to the two side walls 3 of the corner by the prefabricated wall panel 1. The corner decorative strip 2 is assembled and connected to the prefabricated wall panel 1 on the two side walls 3 respectively. This not only makes the installation method of the corner and the wall 3 standardized and uniform, but also makes the installation convenient. In addition, the inner side 23 of the corner decorative strip 2 is spaced apart from or in contact with the corner, so that the corner decorative strip 2 will not interfere with the corner or the wall 3 during installation, avoiding the need for secondary processing of the corner decorative strip 2 and improving the convenience of the installation of the corner decorative strip 2.
[0032] In practice, the way the corner trim strip 2 is assembled and connected to the prefabricated wall panel 1 is not unique. It includes, but is not limited to, connecting the corner trim strip 2 to the prefabricated wall panel 1 by means of screws, bolts, clips, etc.
[0033] In some alternative embodiments, the prefabricated wall panel 1 is provided with a first assembly part on the side near the external corner, and the external corner decorative strip 2 is provided with a second assembly part on the left and right sides respectively, and the first assembly part and the second assembly part are matched and connected.
[0034] Specifically, the first assembly part and the second assembly part cooperate with each other to splice the prefabricated wall panel 1 and the external corner decorative strip 2 together and fix them to the wall surface 3.
[0035] In an optional embodiment, the first assembly part includes a first groove 11, which is disposed on the end face of the prefabricated wall panel 1 near the external corner. The second assembly part includes a second groove 21, which is disposed on the end faces of the left and right sides of the external corner decorative strip 2. The first groove 11 and the second groove 21 cooperate with the I-beam 4 to fix the prefabricated wall panel 1 and the external corner decorative strip 2 together on the wall surface 3.
[0036] Specifically, in combination Figure 4 For example, the I-beam 4 includes two flange plates 41 and a web plate 42. The two flange plates 41 are arranged in parallel, and the web plate 42 is disposed between the two flange plates 41, with both ends of the web plate 42 connected to the two flange plates 41 respectively. When assembling and connecting the prefabricated wall panel 1 and the corner trim 2, one flange plate 41 of the I-beam 4 is first fixed to the wall surface 3 with screws. Then, the first groove 11 on the prefabricated wall panel 1 and the second groove 21 on the corner trim 2 are respectively inserted into the two sides of the other flange plate 41 of the I-beam 4, so that the prefabricated wall panel 1 and the corner trim 2 are snapped onto the I-beam 4, achieving the effect of fixing it to the wall surface 3, and making the prefabricated wall panel and the corner trim 2 fit together.
[0037] Of course, in practice, the first assembly part and the second assembly part can also be other structures, and are not limited to the structure of the first groove 11 and the second groove 21 described above. This utility model does not limit them in this regard.
[0038] In this embodiment, the prefabricated wall panel and the corner trim 2 are assembled together by the first groove 11 and the second groove 21 in cooperation with the I-beam 4, and are firmly fixed to the wall surface 3. This assembly and connection method has a simple structure and is conducive to quickly completing the assembly and installation of the prefabricated wall panel and the corner trim 2.
[0039] Furthermore, when fixing the prefabricated wall panel 1 to the wall surface 3, a leveling component can be installed on the wall surface 3 to level it first, and then the prefabricated wall panel 1 can be fixedly connected to the leveling component to ensure that the prefabricated wall panel 1 is flatly and fixedly connected to the wall surface 3. Alternatively, the wall surface 3 can be leveled first, and the prefabricated wall panel 1 can be directly fixedly connected to the leveled wall surface 3 without using a leveling component, thus saving material costs.
[0040] In some alternative embodiments, leveling components are connected to the two side walls 3, and the prefabricated wall panels 1 are connected to the leveling components.
[0041] Specifically, the leveling component is preferably a keel 5. First, the keel 5 is installed on the wall surface 3 to level it. Then, the prefabricated wall panel 1 is fixedly connected to the keel 5. For example, one flange plate 41 of the I-beam 4 is fixed to the keel 5. Then, the first groove 11 on the prefabricated wall panel 1 and the second groove 21 on the corner trim 2 are inserted into both sides of the other flange plate 41 of the I-beam 4 to fix the prefabricated wall panel 1 and the corner trim 2 to the wall surface 3, and to splice the prefabricated wall panel 1 and the corner trim 2 together. In this embodiment, by installing a leveling component on the wall surface 3, the prefabricated wall panel 1 is ensured to be flatly and fixedly connected to the wall surface 3.
[0042] In practice, the outer surface 22 of the corner trim strip 2 can be constructed into various shapes to meet different decorative needs.
[0043] In some alternative embodiments, the outer surface 22 of the corner trim strip 2 is a flat surface, a curved surface, a corner surface, or an irregular surface.
[0044] Specifically, in combination Figure 5 Specifically, the outer surface 22 of the corner trim 2 is curved, specifically an arc surface. By designing the outer surface 22 of the corner trim 2 as an arc surface, it not only achieves the effect of decorating the corner as a curved surface, but also avoids the corner from being easily damaged during use.
[0045] Furthermore, in an alternative embodiment, the outer side 22 of the corner trim strip 2 is connected with a decorative layer.
[0046] Specifically, the finishing layer includes, but is not limited to, patterns, colors, or combinations thereof. By adding a finishing layer to the outer surface 22 of the corner trim 2, the applicability of the corner trim 2 can be further enhanced, meeting various decorative requirements.
[0047] Furthermore, the outer surface 22 of the corner trim 2 is for decoration, while the inner surface 23 is for preventing interference with the corner during installation; their functions are different. Therefore, structurally, the outer surface 22 and the inner surface 23 of the corner trim 2 are preferably different. For example, combining... Figure 5 For example, the outer surface 22 of the corner trim 2 is an arc surface, while the inner surface 23 of the corner trim 2 is an irregular surface.
[0048] In some alternative embodiments, the outer side 22 and the inner side 23 of the corner trim strip 2 form a hollow cavity 24.
[0049] Specifically, in combination Figure 5In this embodiment, the outer surface 22 and the inner surface 23 of the corner trim 2 have different shapes. The outer surface 22 of the corner trim 2 is an arc surface, while the inner surface 23 of the corner trim 2 is an irregular surface with multiple curved surfaces that bend along the length of the corner trim 2. By constructing a hollow cavity 24 between the outer surface 22 and the inner surface 23 of the corner trim 2, on the one hand, material usage can be reduced, costs can be saved, and the weight of the corner trim 2 can be reduced; on the other hand, when the inner surface 23 contacts the corner, if the inner surface 23 is compressed, the inner surface 23 is allowed to indent into the hollow cavity 24 to offset the compression caused by the contact, thereby preventing overall deformation of the corner trim 2.
[0050] In some optional embodiments, a hollow cavity 24 is formed between the outer side 22 and the inner side 23 of the corner trim 2. At least one support strip 25 is provided in the hollow cavity 24. The support strip 25 extends along the corner direction and is connected to the outer side 22 and the inner side 23 respectively. The position where the inner side 23 of the corner trim 2 contacts the corner corresponds to the position of one of the support strips 25.
[0051] Specifically, the support strip 25 is disposed between the outer surface 22 and the inner surface 23 of the corner trim strip 2 to improve the overall strength of the corner trim strip 2 and prevent it from easily deforming. In practice, the support strip 25 can be disposed on both sides of the corner trim strip 2, or in the middle of the corner trim strip 2, or between the middle and both sides of the corner trim strip 2.
[0052] Preferably, in this embodiment, a support strip 25 is provided inside the hollow cavity 24, and the support strip 25 is located on the center line of the external corner decorative strip 2.
[0053] Specifically, the width of the support strip 25 is less than or equal to the distance between the inner side 23 and the outer side 22 of the corner trim strip 2 at other locations, so as to avoid interference between the inner side 23 and the corner when installing the corner trim strip 2, and at the same time improve the overall rigidity of the corner trim strip 2.
[0054] In some alternative embodiments, the corner trim 2 has a mirror-symmetric structure, and the axis of symmetry is the plane where the support strip 25 is located.
[0055] Specifically, the corner trim strip 2 has a symmetrical structure, which can distribute the force more evenly when subjected to external forces (such as collisions or compressions), reducing the risk of local deformation or damage to the strip.
[0056] Please see Figure 1 and Figure 5In some other embodiments of this utility model, a corner decorative strip 2 is also provided. The corner decorative strip 2 is assembled and connected to the prefabricated wall panel 1 on the two side walls 3 of the corner. The inner side 23 of the corner decorative strip 2 is spaced apart from or in contact with the corner.
[0057] Specifically, the implementation method of the external corner decorative strip 2 can be referred to the above embodiments, and will not be repeated here.
[0058] In practical applications, combined with Figures 1 to 5 The installation steps for corner trim strip 2 are as follows:
[0059] S1, Determine the installation position of the external corner decorative strip 2;
[0060] S2, insert I-beams 4 on both sides of the corner decorative strip 2, and fix the I-beams 4 to the wall 3 with screws;
[0061] S3, insert the prefabricated wall panel 1 into the I-beams 4 on both sides of the corner trim strip 2 to complete the installation of the corner trim strip 2 and the prefabricated wall panel 1 at the corner position.
[0062] In this embodiment, the corner trim strip 2 is assembled and connected to the prefabricated wall panels 1 on both sides of the wall 3, so that the installation method of the corner and the wall 3 is standardized and uniform. Furthermore, the inner side 23 of the corner trim strip 2 is spaced apart from or in contact with the corner, so that the corner trim strip 2 will not interfere with the corner or the wall 3 during installation, avoiding the need for secondary processing of the corner trim strip 2 and improving the convenience of installation.
[0063] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
