Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a keel structure suitable for wall corners. Background Art

[0002] Existing wall tiles are generally installed by dry hanging. Please refer to the Chinese patent document with publication number CN113863603A. The wall tiles are generally dry hung by cooperating with a keel (i.e., the wall shank in the patent document), a fixing bracket and a clip. First, the keel (i.e., the wall shank in the patent document) is fixed to the wall by expansion bolts, and the fixing bracket is fixed to the keel frame by the cooperation of bolts and nuts. Finally, the wall tiles are installed in a limited position by cooperating with the clip and the fixing bracket.

[0003] When the above-mentioned keel is used for installation at a corner (i.e., the installation surfaces perpendicular to each other on the wall), keels need to be installed on the two perpendicular surfaces respectively, which makes the installation process cumbersome and the installation efficiency low. Therefore, this application provides a keel structure suitable for the corner of the wall to meet the needs. Utility Model Content

[0004] The purpose of this application is to provide a keel structure suitable for wall corners, which is used to solve the technical problem in the prior art that the keels need to be installed separately on two mutually perpendicular surfaces, resulting in a cumbersome installation process and low installation efficiency.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a keel structure suitable for the corner of a wall, comprising a circular strip with a notch at one corner, mounting plates vertically bent at both edges of the notch, and mounting holes provided on the mounting plates, through openings adapted for fixing brackets provided on the two vertical surfaces of the circular strip opposite to the notch, an L-shaped plate fixed on the inner wall of the circular strip near the through opening, and threaded holes provided on the L-shaped plate at positions corresponding to the through openings.

[0006] As a preferred implementation in this embodiment, accommodating grooves are provided on both planar ends of the paper-shaped strip.

[0007] As a preferred implementation manner in this embodiment, a bottom sealing plate is provided at the lower end of the accommodating groove for sealing the lower end opening of the accommodating groove.

[0008] As a preferred implementation in this embodiment, the bottom cover plate is fixedly connected to the inner wall of the accommodating groove via a connecting plate, and a pre-fold is provided on the connecting plate.

[0009] As a preferred implementation in this embodiment, the inner cavity of the accommodating groove is arranged in a straight line from top to bottom with a plurality of blind holes arranged obliquely upward.

[0010] In summary, the technical effects and advantages of the utility model are:

[0011] The utility model has a reasonable structure. The keel is set as a circular structure with a notch. It only needs to install one keel at the corner, and there is no need to set a keel on two perpendicular surfaces at the corner. The use of the keel reduces the installation process and improves the installation efficiency.

[0012] In the present invention, receiving grooves are provided on both flat ends of the circular strip, and the receiving grooves are filled with fixing glue. The fixing glue fixes the wall tiles to the U-shaped keel plate, thereby ensuring the stability of the wall tiles and preventing them from loosening. While meeting the installation process requirements, since the fixing glue is only filled into the receiving cavity of the smaller receiving groove, less fixing glue is used to complete the fixation of the wall tiles to the keel, greatly saving installation costs.

[0013] In the present invention, a bottom sealing plate is provided at the lower end of the accommodating groove, and the bottom sealing plate is used to seal the lower end opening of the accommodating groove, thereby preventing the fixing glue added to the accommodating groove from flowing out of the lower end opening, thereby avoiding unnecessary waste of the fixing glue;

[0014] In the utility model, pre-folds are provided on the connecting plate, and the bottom cover plate can be knocked out according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: Reference Figure 1-2 The keel structure shown is suitable for the corner of the wall, including a circular strip 1 with a notch 2 at one corner, and mounting plates 3 are vertically bent at both edges of the notch 2, and mounting holes are provided on the mounting plates 3. Through openings 4 that are adapted to the fixing bracket 12 are provided on the two vertical surfaces opposite to the notch 2 of the circular strip 1, an L-shaped plate 9 is fixed on the inner wall of the circular strip 1 near the through opening 4, and threaded holes 10 are provided on the L-shaped plate 9 at positions corresponding to the through openings 4.

[0024] Install this keel as follows Figure 5 When installed at the corner of the wall as shown, only one keel needs to be installed. When installing with the original keel, a keel needs to be installed on two perpendicular surfaces at the corner. Using this keel reduces the installation process and improves the installation efficiency.

[0025] After the keel is installed, one mounting plate provided on the fixing bracket 12 (which is basically the same as the fixing bracket structure in the patent document, except that the position of the mounting plate is different) passes through the through opening 4, and the other mounting plate fits against the outer wall of the circular strip 1, and then the fixing bracket 12 is installed on the keel by bolts, and then the wall tiles are placed.

[0026] As a preferred implementation in this embodiment, Figure 1 As shown, accommodating grooves 5 are provided on both planar ends of the circular strip 1 .

[0027] After the wall tiles are dry-hung, fixing glue is injected into the accommodating cavity from the upper end opening of the accommodating groove 5. The fixing glue flows downward along the vertically arranged accommodating groove 5, and the accommodating groove 5 is filled with fixing glue. The wall tiles and the U-shaped keel plate 1 are fixed together by the fixing glue, which ensures the stability of the wall tiles and prevents them from loosening. While meeting the installation process requirements, since only the fixing glue is filled into the accommodating cavity of the smaller accommodating groove 5, less fixing glue is used to complete the fixation of the wall tiles and the keel, which greatly saves installation costs.

[0028] It should be noted that when filling the fixing glue, the lower end opening of the lowest accommodating groove 5 needs to be blocked to prevent the fixing glue from flowing out of the lower end opening.

[0029] As a preferred implementation in this embodiment, Figure 3 As shown, a bottom sealing plate 6 is provided at the lower end of the accommodating groove 5 for sealing the lower end opening of the accommodating groove 5 .

[0030] The bottom opening of the receiving groove 5 is sealed by the bottom sealing plate 6 to prevent the fixing glue added to the receiving groove 5 from flowing out of the bottom opening, thereby avoiding unnecessary waste of the fixing glue.

[0031] As a preferred implementation in this embodiment, Figure 3 As shown, the bottom cover plate 6 is fixedly connected to the inner wall of the accommodating groove 5 via a connecting plate 7 , and a pre-fold 8 is provided on the connecting plate 7 .

[0032] The bottom cover plate 6 can be removed according to actual needs. Due to the presence of the pre-fold 8 (where the connection is weak), when the bottom cover plate 6 is no longer needed, the bottom cover plate 6 can be directly knocked off so that the fixing glue can flow from the previous accommodating cavity to the next accommodating cavity.

[0033] As a preferred implementation in this embodiment, Figure 1 and Figure 4 As shown, the inner cavity of the accommodating groove 5 is arranged in a straight line from top to bottom with a plurality of blind holes 11 arranged obliquely upward.

[0034] The setting of the blind hole 11 increases the surface area of ​​the inner wall of the accommodating groove 5, provides more attachment points for the fixing glue, and enhances the connection strength between the keel and the wall tiles. The blind hole 11 is set obliquely upward. The fixing glue in the blind hole 11 forms a hooking effect on the wall tiles after curing, making it difficult for the wall tiles to separate from the keel, thus preventing the wall tiles from falling off, thereby further improving the stability of the wall tile installation.

[0035] It should be noted that the angle between the blind hole 11 and the horizontal plane is not less than 30°. Within this angle range, a good hook can be formed for the wall tiles, thereby improving the connection strength between the keel and the wall tiles.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
