[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The core of the present utility model is to provide a combined F-shaped keel structure, which is a detachable and assembled structure, convenient for disassembly and assembly, transportation and adjustment.

[0025] Please refer to Figure 2 , this application provides a combined F-shaped keel structure, including a U-shaped plate 1 and an inverted L-shaped plate 2 that are integrally formed. The bottom end of the U-shaped plate 1 is provided with a first clamping portion, and the top end of the inverted L-shaped plate 2 is provided with a second clamping portion. The first clamping portion and the second clamping portion are clamped and matched.

[0026] Specifically, both the U-shaped plate 1 and the inverted L-shaped plate 2 are cold-pressed from strip steel. The bottom end of the U-shaped plate 1 is provided with a first clamping portion, and the top end of the inverted L-shaped plate 2 is provided with a second clamping portion. The detachable connection between the U-shaped plate 1 and the inverted L-shaped plate 2 is realized through the clamping and matching of the first clamping portion and the second clamping portion. Among them, the clamping structures of the first clamping portion and the second clamping portion are not unique, and a groove-type clamping structure, a lock-type clamping structure, a lapped-type clamping structure, etc. can be adopted.

[0027] Therefore, the disassembly and assembly of the F-shaped keel structure can be realized in this application, which is not only convenient for transportation but also convenient for adjustment. Especially in the keel ceiling operation, the disassembly and assembly of the keel structure are convenient, and it is convenient to adjust the ceiling shape.

[0028] Considering the specific connection method between the first clamping portion and the second clamping portion, on the basis of the above embodiment, please refer to Figure 2 , the first clamping portion is set as a first燕尾槽11, the second clamping portion is set as a second燕尾榫22, and the first燕尾槽11 is clamped with the second燕尾榫22.

[0029] It can be understood that the U-shaped plate 1 and the inverted L-shaped plate 2 are clamped by a燕尾槽 and a燕尾榫, that is, a mortise and tenon connection. Both the燕尾槽 and the燕尾榫 are trapezoidal, with a large stress area, making the connection surface more stable and reliable, not easy to loosen. Compared with the conventional riveting connection, the firmness of the connection between the U-shaped plate 1 and the inverted L-shaped plate 2 is greatly improved, thereby improving the bearing capacity of the F-shaped keel structure.

[0030] Considering the specific setting method of the first燕尾槽11, on the basis of the above embodiment, please refer to Figure 3 , the bottom end of the U-shaped plate 1 is integrally provided with a first燕尾榫12 protruding away from the inverted L-shaped plate 2, and the first燕尾槽11 is arranged in the first燕尾榫12 in the thickness direction.

[0031] Specifically, a trapezoidal protrusion, i.e., the first dovetail tenon 12, which protrudes towards the top end, is provided at the bottom end of the U-shaped plate 1. This trapezoidal protrusion is integrally formed with the U-shaped plate 1 and is provided with a trapezoidal groove, i.e., the first dovetail groove 11, in the thickness direction. The notch of this trapezoidal groove is arranged facing away from the top end of the U-shaped plate 1 and is used for snap-fitting with the second dovetail tenon 22 at the top end of the inverted L-shaped plate 2. By adopting the above structure to set the first dovetail groove 11, the depth of the first dovetail groove 11 can be maximally increased to ensure the firm snap-fitting of the first dovetail groove 11 and the second dovetail tenon 22.

[0032] In one embodiment, please refer to Figure 4 , the second dovetail tenon 22 is provided with a second dovetail groove 21 in the thickness direction for mortise and tenon connection with its adjacent keel structure. That is to say, the second dovetail tenon 22 is provided with a trapezoidal groove, i.e., the second dovetail groove 21, in the thickness direction. The notch of this trapezoidal groove is arranged facing away from the U-shaped plate 1 and can be used for mortise and tenon connection with other keel structures, thus facilitating the disassembly and assembly between the keel structures and further improving the convenience of building the keel ceiling.

[0033] In another embodiment, please refer to Figure 4 , a connecting plate 3 is provided on one side of the top end of the inverted L-shaped plate 2 far from its bent portion. The connecting plate 3 is provided with a third dovetail groove 31 for mortise and tenon connection with its adjacent keel structure. Thus, the keel structure can be mortise and tenon connected with other keel structures through the third dovetail groove 31 on the connecting plate 3. Not only the connection strength is improved, the stability of the keel ceiling structure can be ensured, but also the connection is more convenient, and the convenience of building the ceiling can be improved.

[0034] Considering the specific setting method of the third dovetail groove 31, on the basis of the above embodiment, please refer to Figure 4 , the connecting plate 3 is provided with a third dovetail tenon 32 that protrudes towards the other side of the inverted L-shaped plate 2. The third dovetail tenon 32 is provided with a third dovetail groove 31 in the thickness direction.

[0035] Specifically, the connecting plate 3 is provided with a trapezoidal protrusion, i.e., the third dovetail tenon 32, that protrudes towards the other side of the inverted L-shaped plate 2 with a bent portion. This trapezoidal protrusion is provided with a trapezoidal groove, i.e., the third dovetail groove 31, in the thickness direction. The notch of this trapezoidal groove is arranged facing away from the inverted F-shaped plate. The depth of the third dovetail groove 31 can be maximally increased to ensure the firm connection of adjacent keel structures.

[0036] Furthermore, please refer to Figure 4 , the connecting plate 3 is integrally formed with the inverted L-shaped plate 2 and is perpendicular to one side of the top end of the inverted L-shaped plate 2 far from its bent portion. Thus, the connecting plate 3 and the inverted L-shaped plate 2 are vertically connected as a whole, which can greatly improve their bearing capacity.

[0037] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0038] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0039] The above is a detailed introduction to the combined F-shaped keel structure provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is only intended to help understand the method and core concept of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, various improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
