Description

Technical Field

[0001] The utility model relates to the technical field of corner keels, in particular to a countersunk hole type corner keel. Background Art

[0002] Corner keels are a commonly used supporting element in building structures, usually used to connect the corners between walls or floors. The main function is to provide support and reinforcement to enhance the stability and strength of the building structure. Although many corner keels currently have countersunk holes to hide the rivet heads, due to the large number of holes, the rivets may be exposed, resulting in an uneven surface. Secondly, due to the dense holes, it is easy to hit the existing holes when self-tapping, affecting the firmness of the connection.

[0022] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present disclosure will be more comprehensive and complete, and the concept of the example embodiments will be fully conveyed to those skilled in the art.

[0023] The utility model provides Figure 1 and Figure 5 A countersunk hole type corner keel shown includes an arc plate 1 and a connector 2. Side plates 3 are fixedly connected to both sides of the arc plate 1. The arc plate 1 is the main part of the corner keel. The side plates 3 are fixed to both sides of the arc plate 1 to play a supporting and fixing role. A concave connecting block 4 is punched from the inside to the outside. A plurality of through holes 5 are opened on one side of the inner wall of the connecting block 4. The combination of the through holes 5 and the connecting block 4 is a countersunk hole structure. The setting of the connecting block 4 can improve the strength of the corner keel. The combined countersunk holes can make the surface of the product smoother after being fixed with bolts. Moreover, the corner keel in this application is formed by cold bending machinery and cold pressing in one step, and has higher strength than the prior art in this application.

[0024] By setting the connection block 4, the connection block 4 and the through hole 5 are combined to form a countersunk hole, and the rivet head used during installation can be hidden by setting the countersunk hole. This design improves the flatness and aesthetics of the structure after installation. In the subsequent use process, the hidden rivet head will not cause unevenness or protrusions, which effectively improves work efficiency.

[0025] The two side panels 3 are respectively fixedly connected with a guide frame 6 and a guide bar 7 on the side away from the arc-shaped panel 1. The cross section of the guide frame 6 is L-shaped, and a sliding space for the connecting member 2 to slide is formed between the guide frame 6 and the guide bar 7. The guide frame 6 and the guide bar 7 are respectively fixed on the two side panels 3, and a sliding space is formed on the side away from the arc-shaped panel 1. This sliding space can be used for the sliding movement of the connecting member 2, so that the whole structure has certain flexibility and adjustability.

[0026] Furthermore, a connecting piece 9 located in the guide frame 6 is fixedly connected to the top of the sliding frame 8, a guide groove 10 adapted to the guide bar 7 is provided on the first side below the sliding frame 8, and a plurality of through grooves 11 are provided through the second side below the sliding frame 8. The bottom of the sliding frame 8 fits under the connecting block 4, and the connecting piece 9 is located in the guide frame 6, which can provide stable support and fixation, ensuring that the connecting member 2 will not loosen or fall off during use, thereby increasing the safety of the structure. Through the design of the sliding frame 8 and the guide groove 10, the connecting member 2 can slide horizontally on the corner keel, thereby realizing the adjustment of the position of the connecting member 2.

[0027] Furthermore, a slope is provided on one side of the sliding frame 8 facing the connecting block 4, and the spacing between the two connecting blocks 4 is smaller than the width of the sliding frame 8. The spacing between the connecting blocks 4 is set to prevent the subsequent connecting blocks 4 from affecting the sliding of the connecting member 2, and the setting of the slope facilitates the subsequent fixing of the corner keel with screws, and prevents the connecting member 2 from blocking the connecting block 4.

[0028] Furthermore, a plurality of grooves 12 are provided through the second side of the side panel 3, and the grooves 12 are located between two adjacent connection blocks 4. A plurality of movable sheets 13 are movably connected above the edges of the grooves 12, and a movable space is left between the movable sheets 13 and the second side of the side panel 3, and the space of the grooves 12 is larger than the space of the movable sheets 13. By setting the movable sheets 13, the keel can abut against the mounting portion when it contacts the mounting portion, so as to increase the friction when the corner keel contacts the mounting portion. When the corner keel contacts the mounting portion, the movable sheets 13 will automatically abut against the mounting portion, increasing the friction between the corner keel and the mounting portion to improve the stability of the connection, and when the corner keel is fixed, the movable sheets 13 will be subjected to the squeezing force, and then folded into the grooves 12 to make the side panel 3 and the mounting portion fit tightly together.

[0029] Furthermore, the inner wall of the arc-shaped plate 1 is provided with a plurality of reinforcing ribs 14 arranged in a spiral shape. The provision of the reinforcing ribs 14 can improve the strength of the subsequent arc-shaped plate 1, thereby preventing the two side plates 3 of the subsequent corner keel from folding.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
