Detailed implementation manners

[0028] The present invention will be further described below in conjunction with the accompanying drawings of the specification and specific embodiments. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention involved in the following description are usually only some of the embodiments of the present invention, rather than all of the embodiments. Therefore, all other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0029] Referring to Figures 1 to 7 An engaging and kneading load-bearing keel shown, which includes a main keel 1 and an engaging keel 2. The number of the main keel 1 and the engaging keel 2 is determined according to the house type to be decorated. A plurality of main keels 1 and a plurality of engaging keels 2 are arranged horizontally and vertically in a crosswise manner. The engaging keel 2 is located below the main keel 1, and the engaging keel 2 is engaged with the main keel 1.

[0030] The cross-sectional shape of the main keel 1 is in a U-shape. The main keel 1 includes a bottom plate 11, two waist plates 12, and two attaching top plates 13. The bottom plate 11 is horizontally arranged. The waist plates 12 are connected to both ends of the bottom plate 11 and are symmetrically arranged with respect to the midline of the bottom plate 11 in a mirror image manner. An obtuse angle is formed between the waist plate 12 and the bottom plate 11. In addition to the obtuse angle, a right angle is also possible, but the obtuse angle is the best. This obtuse angle can be further limited to between 110 degrees and 140 degrees. The purpose of setting it as an obtuse angle is to improve the structural strength of the main keel 1. The two attaching top plates 13 are respectively connected to one waist plate 12 and are arranged parallel to the bottom plate 11. The main keel 1 is installed on the wall top through expansion screws 3. The attaching top plate 13 is in contact with the wall top, and the bottom plate 11 is located below the attaching top plate 13. A trapezoidal space is formed between the bottom plate 11 and the two waist plates 12, and this space is used to cooperate with the installation of the engaging keel 2. A plurality of hanging holes 111 are arranged at intervals along the length direction on the bottom plate 11 for the engagement of the engaging keel 2. A plurality of installation holes 112 are also provided on the bottom plate 11. The installation holes 112 serve as hanging points for the installation of the expansion screws 3. After the main keel 1 is installed on the wall top, for the installation of the engaging keel 2, the engaging keel 2 needs to be lifted, the hook of the engaging keel 2 is extended into the main keel 1 through the hanging hole 111, and then translated and misaligned with the hanging hole 111 so that the engaging keel 2 is engaged on the bottom plate 11.

[0031] As a preferred embodiment, the engaging keel 2 includes a horizontally arranged main body plate 21. One side of the main body plate 21 is provided with a side plate 22 perpendicular to it. The top of the side plate 22 is provided with a mounting plate 23 horizontally extending towards the opposite side of the side plate 22. The end of the mounting plate 23 is provided with a hook plate 24 bent towards the side plate 22. An acute angle is formed between the hook plate 24 and the mounting plate 23. A plurality of notches 25 are formed on the mounting plate 23 and the hook plate 24. The notches 25 on the mounting plate 23 and the notches 25 on the hook plate 24 are arranged in one-to-one correspondence. Through the notches 25, the mounting plate 23 and the hook plate 24 are segmented into a plurality of hook portions 26, and these hook portions 26 are engaged on the main keel 1. The hanging hole 111 is a square hole, and the distance between the hanging holes 111 is equal to the width of the mounting plate 23. In this way, after the hook portion 26 is engaged on the main keel 1, the mounting plate 23 is carried on the solid part between the hanging holes 111, and the hook plate 24 can abut against the side wall of the hanging hole 111, so that the engaging keel 2 is locked, improving the overall stability.

[0032] Furthermore, the engaging keel 2 is made of metal. After the hook portion 26 is engaged on the main keel 1, the hook plate 24 is perpendicular to the mounting plate 23 before installation to facilitate the extension of the hook portion 26 into the hanging hole 111. After the mounting plate 23 is carried, the hook plate 24 can be bent towards the side plate 22 under an external force to further improve the stability of the engaging keel 2.

[0033] An avoidance hole 27 is provided at a position corresponding to each notch 25 on the side plate 22 of the snap-in keel 2. Since there is an upward movement when installing the snap-in keel 2, the avoidance hole 27 is used to prevent interference caused by the side plate 22.

[0034] As a preferred embodiment, because the width of the hook portion 26 is limited and the spacing between the hanging holes 111 is restricted, if the mounting holes 112 serving as hanging points on the main keel 1 are opened between the hanging holes 111, the strength will be insufficient, which may cause the bottom plate 11 of the main keel 1 to crack. Therefore, the bottom plate 11 is divided into several sections at intervals according to a certain length. For the convenience of description, they are called hanging hole opening sections 113. Between the hanging hole opening sections 113 are mounting hole opening sections 114, and the length of the mounting opening section can be 5 to 8 cm.

[0035] As a preferred embodiment, considering that the main keel 1 is installed on the wall top through expansion bolts, but the wall tops are not exactly the same, and it cannot be completely ensured that the positions of the hanging points are exactly at the positions of the mounting holes 112 provided on the main keel 1. If additional hanging points are needed, mounting holes 112 need to be opened in the hanging hole opening sections 113, which may lead to the above-mentioned problem of insufficient strength. Therefore, the present invention is provided with a C-shaped member 4. The C-shaped member 4 is attached to the inner side surface of the main keel 1, which can stabilize the structure of the main keel 1.

[0036] The installation method of the snap-in and pinch-bearing keel includes the following steps:

[0037] The first step: Snap lines on the wall surface and the top surface;

[0038] The second step: Fix the main keel 1 to the wall top with expansion screws 3 in sequence;

[0039] The third step: Align the hook portion 26 of the snap-in keel 2 with each main keel 1, then lift the snap-in keel 2. After lifting, translate the snap-in keel 2 and then lower the snap-in keel 2 so that the mounting plate 23 of the snap-in keel 2 is carried on the main keel 1. Finally, pinch the hook plate 24 of the hook portion 26 to bend the hook plate 24 toward the side plate 22 to complete the installation;

[0040] The fourth step: Install the snap-in keels 2 in sequence according to the third step.

[0041] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
