Description

TECHNICAL FIELD

[0001] The utility model relates to the field of construction decoration, especially to a clamping type ceiling and floor stud. BACKGROUND

[0002] The light steel stud partition wall is a building partition wall system made of light steel, which mainly comprises a stud frame, a gypsum board or a fiber cement board and a filler. In the stud frame, the ceiling and floor stud refers to the part of the light steel stud partition wall system connected with the roof and the floor. The main function of the ceiling and floor stud is to provide stable top and bottom support for the partition wall to ensure the stability and integrity of the partition wall.

[0003] In the prior art, the ceiling and floor stud is usually a U-shaped stud. The vertical stud is vertically sleeved in the ceiling and floor stud, and then the two studs are connected and fixed by using screws. This connection method needs to punch holes and screw, and some need to use a special stud wrench to fix the vertical stud. Moreover, a scale is needed to accurately measure and mark the position of the vertical stud. Therefore, the existing limiting and fixing structure is complicated and inconvenient to operate, and the labor intensity is high, which needs to be improved. SUMMARY

[0004] The utility model aims at solving one of the technical problems in the prior art. Therefore, one purpose of the utility model is to provide a clamping type ceiling and floor stud.

[0005] The technical scheme of the utility model is as follows: a clamping type ceiling and floor stud, characterized in that the ceiling and floor stud is a channel steel piece, the middle of the channel steel piece is a bottom plate, the left and right sides are vertical side plates, the inner walls of the two side plates are respectively provided with limiting plates extending along the length direction of the side plates, each limiting plate is respectively provided with a bayonet hole penetrating to the inner side edge of the limiting plate, the bayonet holes are multiple and are arranged at intervals along the length direction of the limiting plate, and the bayonet holes on the two limiting plates are one-to-one opposite.

[0006] Further, the upper edges of the two side edges are respectively inwardly and horizontally folded to form the limiting plates.

[0007] Further, the bayonet hole is a rectangular hole.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] Because this product has built-in snap-fit ​​slots, the vertical keels to be connected can be directly snapped into the slots and securely positioned by the two limiting plates on the top and bottom keels. This eliminates the need for screws or other fasteners and the tedious screw-tightening process, greatly improving construction efficiency, reducing labor intensity, and saving time and effort. Moreover, each top and bottom keel has multiple snap-fit ​​slots, and the vertical keels can be snapped into different slots, allowing the spacing of the vertical keels to be adjusted according to needs, saving many tedious procedures.

[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "inner," "outer," "vertical," "circumferential," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] like Figure 1 and Figure 2 The diagram shows a type of clip-on top and bottom bracket. The top and bottom brackets are channel steel parts. The middle of the channel steel part is a bottom plate 1, and the left and right sides are vertical side plates 2. The inner walls of the two side plates 2 are respectively provided with limiting plates 3 extending along the length direction of the side plates 2. Each limiting plate 3 is provided with a slot 4 that penetrates to the inner edge of the limiting plate 3. There are multiple slots 4, which are arranged at intervals along the length direction of the limiting plate 3. The slots 4 on the two limiting plates 3 are directly opposite each other.

[0020] In the specific design, the upper edges of the two sides are folded inward horizontally to form the limiting plate 3, and the slot 4 is a rectangular opening, which facilitates the manufacturing and processing of the product.

[0021] Because this product has built-in snap-fit ​​4, the vertical keel to be connected can be directly snapped into the snap-fit ​​4 during use, and will be securely limited by the two limiting plates 3 on the top and bottom keels. This eliminates the need for fasteners such as screws and tedious screw-tightening operations, greatly improving construction efficiency, reducing labor intensity, and saving time and effort. Moreover, each top and bottom keel has multiple snap-fit ​​4, and the vertical keel can be snapped into different snap-fit ​​4, so the spacing of the vertical keel can be adjusted according to the needs during use, saving many tedious procedures.

[0022] Although some embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention are all within the scope of protection of the claims of the present invention.
