Description

Technical Field

[0001] The utility model relates to the technical field of ceiling keels, in particular to a large corner guard for connecting the internal corners of ceiling keels. Background Technique

[0002] The light steel keel is a new type of building material. With the development of China's modernization drive, the light steel keel is widely used in decorative ceilings. There are a wide variety of existing keel profiles, which are designed with different structures according to different functional roles and usage parts, and different components need to be assembled and connected through connectors.

[0003] With the improvement of people's requirements for decoration styles, there are more and more personalized requirements for the shapes of decorative ceilings, and the quality of ceilings is also pursued to be more perfect. This puts forward higher requirements for the firmness of some shaped corner connection parts. However, there are no special products and accessories for preventing internal corners from being torn in traditional materials. Therefore, if one wants to reinforce the corners, wooden boards must be used for production, which has the disadvantages of non-environmental protection of construction materials, complex production, high costs, etc. Therefore, a new connector for the internal corner parts of keel corners is needed. Content of the Utility Model

[0004] In view of the problems existing in the prior art, the utility model discloses a large corner guard for connecting the internal angles of ceiling keels. The adopted technical solution is that a first side plate, a second side plate, a first folding plate and a second folding plate are respectively bent and processed on the side of the bottom plate. The first side plate and the second side plate are perpendicular to each other. The first side plate and the second side plate have the same structure and are both provided with side plate fixing holes. Nails can pass through the side fixing holes to fix the whole corner guard. The first folding plate and the second folding plate are perpendicular to each other. The first folding plate and the second folding plate have the same structure and are both provided with folding plate connection holes. First fixing plate, second fixing plate, first buckle plate and second buckle plate are respectively bent and processed in the middle of the bottom plate. The first fixing plate and the second fixing plate are perpendicular to each other. The first fixing plate and the second fixing plate have the same structure and are both provided with fixed connection holes. The first fixing plate and the second folding plate are coplanar. The second fixing plate and the first folding plate are coplanar. The first buckle plate is parallel and opposite to the first folding plate, and a closing edge keel connection hole is arranged on the bottom plate between them. The second buckle plate is parallel and opposite to the second folding plate, and the closing edge keel connection hole is also arranged on the bottom plate between them. The closing edge keel connection holes are arranged in two mutually perpendicular columns on the bottom plate. The closing edge keel in the ceiling keel is correspondingly buckled between the first buckle plate and the first folding plate, and between the second buckle plate and the second folding plate. The closing edge keel can be riveted and fixed through the folding plate connection hole, the fixed connection hole and the closing edge keel connection hole by rivets. Straight-edge secondary keel connection holes are respectively arranged on the bottom plate at the sides of the first side plate and the second side plate. The straight-edge secondary keel connection holes are arranged in two mutually perpendicular columns on the bottom plate. An inclined tension secondary keel connection hole is arranged on the bottom plate between the two columns of straight-edge secondary keel connection holes. The straight-edge secondary keel and the inclined tension secondary keel can be riveted and fixed through the straight-edge secondary keel connection hole and the inclined tension secondary keel connection hole by rivets, so that the corner guard can integrally complete the connection at the corner between the secondary keel and the closing edge keel.

[0005] As a preferred solution of the utility model, a bent buckle head is bent and processed on the upper part of the first buckle plate. The second buckle plate has the same structure as the first buckle plate. The closing edge keel can be buckled and fixed through the bent buckle head to achieve rapid installation.

[0006] Advantages of the present utility model: The present utility model is used for the connection at both ends of the internal angle of the ceiling keel. The edge-trimming keel is buckled by the bent buckle heads of the first buckle plate and the second buckle plate, and the edge-trimming keel is buckled between the buckle plate and the folding plate. Then, riveting is carried out through the rivets at the connection holes of the edge-trimming keel and the corresponding holes on the edge-trimming keel to fix the edge-trimming keel. The three groups of secondary keel connection holes arranged on the bottom plate facilitate the fixed connection of the secondary keel to the large corner guard. At the same time, the designed multiple groups of side plates, folding plates and fixing plates, combined with the connection holes opened thereon, facilitate the fixed connection methods in different orientations, facilitating the connection between the large corner guard, the keel and the wall, making the construction of the corner of the entire ceiling keel more convenient and flexible. The prefabricated structural parts have lower costs, and the completed ceiling structure is more firm and environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS
