Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, specifically to a right-angle corner piece for a secondary keel and a vertical docking structure. Background Technology

[0002] Light steel keel is increasingly widely used in interior decoration. By assembling keels into various support structures, diverse interior decoration options are achieved. Existing keel hoisting structures often require adapters for vertical connection of the keels. For example, patent 201510244573.3 discloses a secondary keel mounting bracket, an installation structure and method between secondary keels, and specifically discloses a mounting bracket for vertical connection of secondary keels. This mounting bracket consists of two parts: an adapter and an extension. During use, the adapter and extension respectively cover the outer side of the secondary keels in two directions to provide support. They are connected by bolts to achieve vertical connection of the horizontal and vertical secondary keels. Firstly, this mounting bracket is complex due to its two-part structure, resulting in high production costs. Secondly, the assembly process is cumbersome and inefficient, affecting construction speed. Furthermore, since both the adapter and extension need to cover the outer side of the secondary keel, the outer surface of the secondary keel is uneven, affecting the construction of the outer surface finishing layer of the ceiling structure. Summary of the Invention

[0003] To address the problems in the existing technology, this utility model patent designs a right-angle corner piece and vertical docking structure for a secondary keel, thereby solving the problems of complex structure, high production cost, and poor application effect of existing vertical docking connectors for keels.

[0004] To address the aforementioned problems in the existing technology, this utility model provides a right-angle corner piece for a secondary keel. The right-angle corner piece includes an integrally formed plug-in connection part and a snap-fit ​​connection part. Both the plug-in connection part and the snap-fit ​​connection part are U-shaped grooves, and the two side plates of the snap-fit ​​connection part are respectively provided with slots.

[0005] Furthermore, the bottom plate of the plug-in connection part and the snap-fit ​​connection part of the right-angle corner piece is stepped at the boundary between the two to form a vertical bottom plate.

[0006] Furthermore, the U-shaped groove opening of the engaging connection faces the side with the vertical base plate, and the U-shaped groove opening of the plug-in connection faces the same or opposite direction as the engaging connection.

[0007] Furthermore, the width of the base plate of the facade is smaller than the width of the base plates of the plug-in connection and the snap-fit ​​connection.

[0008] Furthermore, the two side plates of the engaging connection are mushroom-shaped, and slots are formed at both ends of the root of the two side plates.

[0009] Furthermore, a secondary keel snap-fit ​​joint is left between the two side plates of the snap-fit ​​connection part and the bottom plate of the facade.

[0010] The present invention provides a technical solution for a vertically connected secondary keel structure, wherein the vertically connected secondary keel structure includes a horizontal secondary keel, a vertical secondary keel, and a right-angle corner piece of the secondary keel as described above. Both the horizontal and vertical secondary keels are C-shaped keels. The horizontal secondary keel is snapped into the snap-fit ​​connection part of the right-angle corner piece of the secondary keel. The two side plates of the horizontal secondary keel are respectively snapped into the slots at both ends of the side plates of the snap-fit ​​connection part. The insertion connection part is inserted from the end of the vertical secondary keel into the C-shaped slot of the vertical secondary keel.

[0011] Furthermore, the bottom surfaces of the transverse and longitudinal secondary keels of the vertically connected secondary keel structure are flush.

[0012] Compared to existing technologies, the advancements of this utility model patent in designing a right-angle corner piece for secondary keels and a vertical connection structure for keels lie in the following: the right-angle corner piece is a one-piece molded structure, simple and practical, with low manufacturing costs. In use, it can be quickly connected simply by engaging and inserting it into the horizontal and vertical secondary keels, making operation convenient and construction efficient. After connecting the horizontal and vertical secondary keels, the corner piece can be hidden within the secondary keels, ensuring that the surfaces of the horizontal and vertical secondary keels are flush, facilitating subsequent exterior finishing work on the keel support structure.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The technical solutions in the embodiments of the present invention will be clearly and completely described. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0019] like Figure 1 , 2 As shown, this utility model patent designs a right-angle corner piece for a secondary keel. In this embodiment, the right-angle corner piece is integrally stamped and bent from a single metal plate, including an insertion connection part 12 and a snap-fit ​​connection part 11. Both the insertion connection part 12 and the snap-fit ​​connection part 11 are stamped and bent into U-shaped grooves, and their U-shaped grooves can... Figure 1 The opening directions shown are the same, or they can be like... Figure 3 The opening directions shown are opposite. The ends of the two side plates of the plug-in connector 12 are chamfered to facilitate plugging. The bottom plates of the plug-in connector 12 and the snap-fit ​​connector 11 of the right-angle corner piece are stepped at their boundary to form a vertical bottom plate 13. The U-shaped groove opening of the snap-fit ​​connector 11 faces the side where the vertical bottom plate 13 is formed. A section of the same width is punched off from both ends of the vertical bottom plate 13, so that the overall width of the vertical bottom plate 13 is smaller than the width of the bottom plates of the plug-in connector 12 and the snap-fit ​​connector 11. Figure 1 As shown, when the U-shaped groove opening directions of the plug-in connection part 12 and the snap-fit ​​connection part 11 are the same, the height of the vertical base plate 13 should be smaller; as Figure 3 As shown, when the U-shaped groove openings of the plug-in connector 12 and the snap-fit ​​connector 11 are in opposite directions, the height of the facade base plate 13 should be greater. Simultaneously, the height of the facade base plate 13 should be adjusted according to the external dimensions of the secondary keel it is to be connected to, mainly by referencing the heights of the two side plates of the secondary keel and the heights of the folded-over portions at the top of the side plates, to ensure that after docking, the secondary keels in both directions are located on the same plane.

[0020] Both sides of the snap-fit ​​connector 11 are mushroom-shaped, with slots 14 formed at both ends of the base of each side panel. A secondary keel snap-fit ​​joint 15 is left between the two side panels of the snap-fit ​​connector 11 and the bottom panel 13 of the facade, so that when the secondary keel is snapped into the slots 14 at the ends of the two side panels of the snap-fit ​​connector 11, the secondary keel can be smoothly snapped into the slots 14 at the ends of the two side panels of the snap-fit ​​connector 11. Example

[0021] like Figure 4As shown, this utility model patent provides an embodiment of a vertically connected secondary keel structure. In this embodiment, the vertically connected secondary keel structure includes a transverse secondary keel 2, a longitudinal secondary keel 3, and a right-angle corner piece 1 as described in Embodiment 1. Both the transverse secondary keel 2 and the longitudinal secondary keel 3 are C-shaped keels. The transverse secondary keel 2 is snapped into the snap-fit ​​connection part 11 of the right-angle corner piece 1. The two side plates of the transverse secondary keel 2 are respectively snapped into the slots 14 at both ends of the side plates of the snap-fit ​​connection part 11. The insertion connection part 12 is inserted from the end of the longitudinal secondary keel 3 into the C-shaped slot of the longitudinal secondary keel 3. After docking, the bottom surfaces of the transverse secondary keel 2 and the longitudinal secondary keel 3 are flush.
