Abstract
Description
Technical Field
[0001] This utility model relates to the field of building decoration technology, and more specifically, to a ceiling recessed keel structure. Background Technology
[0002] A recessed groove in the ceiling refers to a groove formed at the junction of the ceiling and the wall. It is usually located at the edge of the ceiling and is used to hide the seams and provide space for installing equipment such as light strips. This design not only helps to hide the seams, but also increases the overall aesthetics and functionality of the ceiling.
[0003] In the traditional process of constructing recessed corner ceilings, several keel structures are riveted and spliced together according to the ceiling space at the construction site. Before constructing the recessed corner ceiling, the keel structure is repeatedly cut, riveted, and shaped according to the structural characteristics of the required recess. This method has the following disadvantages: First, the construction of the recessed corner ceiling by riveting and splicing several keel structures not only makes the construction cumbersome but also results in a large tensile load on the keel structure, making it unstable and prone to damage. Second, the keel structure is not a single piece but rather multiple keels cut and spliced together, which is not only cumbersome to process but also wastes excessive materials, resulting in high construction costs for the recessed corner ceiling.
[0004] In summary, how to provide a keel structure that is easy to build, low in cost, and structurally stable for recessed corners in suspended ceilings is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a ceiling corner groove keel structure that can save the construction cost of ceiling corner grooves, improve the structural stability of ceiling corner grooves, and simplify operation.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A ceiling recessed corner keel structure includes a central right-angle plate integrally bent and two side right-angle plates and a side plate located on both sides of the central right-angle plate. The side right-angle plates adjacent to the central right-angle plate are used to be set against the wall. The two plates of the central right-angle plate form a ceiling recessed corner. The side right-angle plates away from the central right-angle plate are provided with a first snap-fit part for engaging with a second snap-fit part of the adjacent keel structure. The side plate is used to cover the exterior with decorative panels.
[0008] Preferably, the first snap-fit portion is configured as a downwardly protruding dovetail tenon, and the dovetail tenon is provided with a dovetail groove in the thickness direction to fit it, the dovetail groove being used to fit the dovetail tenon on the adjacent keel structure.
[0009] Preferably, the first clamping part is integrally formed with the plate body of the side right-angle plate away from the middle right-angle plate.
[0010] Preferably, the plate body of the side right-angle plate away from the middle right-angle plate is located directly above the middle right-angle plate.
[0011] Preferably, the bending part between the side right-angle plate and the middle right-angle plate is a right angle.
[0012] Preferably, the bending part between the side flat plate and the middle right-angle plate is provided with a downwardly protruding flange.
[0013] Preferably, the side flat plate and the plate body of the middle right-angle plate adjacent thereto are perpendicular.
[0014] Preferably, the length of the side flat plate is about 30 mm, and the width thereof is about 29.5 mm.
[0015] Preferably, the height of the plate body of the middle right-angle plate adjacent to the side flat plate is about 10 mm, and the width thereof is about 29.5 mm.
[0016] Preferably, the length of the plate body of the middle right-angle plate adjacent to the side right-angle plate is about 10 mm, and the width thereof is about 29.5 mm.
[0017] Preferably, the height of the plate body of the side right-angle plate adjacent to the middle right-angle plate is about 20 mm, and the width thereof is about 29.5 mm.
[0018] Preferably, the length of the plate body of the side right-angle plate away from the middle right-angle plate is about 20 mm, and the width thereof is about 29.5 mm.
[0019] Preferably, the maximum distance between the side right-angle plate and the side flat plate in the length direction is about 39.5 mm.
[0020] Preferably, the maximum outer diameter of the dovetail is about 4.5 mm.
[0021] The ceiling corner recess keel structure provided by this utility model is integrally molded, which not only has a strong load-bearing capacity, improving the structural stability of the ceiling corner recess, but also saves processing costs and construction costs. Furthermore, during the installation of the ceiling corner recess keel, the number of splicing keel structures is determined according to the depth of the corner recess. The side right-angle plates of two adjacent keel structures, away from the central right-angle plate, are spliced together by two interlocking parts, while the plates adjacent to the central right-angle plate are all set against the wall. Thus, the two plates of the central right-angle plates of several keel structures, together with the wall, form the ceiling corner recess, and the side plates of several keel structures are all covered with decorative panels. Therefore, the interlocking of several keel structures to form the ceiling corner recess is simpler to operate than riveting splicing, improving the construction efficiency of the ceiling corner recess, and avoiding excessive tensile force on the keel structure, making the connection of several keel structures more stable, thereby improving the structural stability of the ceiling corner recess.

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.
[0030] The core of the present application is to provide a ceiling concave corner keel structure, which can save the construction cost of the ceiling concave corner, improve the structural stability of the ceiling concave corner and is simple to operate.
[0031] Please refer to Figure 1 The present application provides a ceiling concave corner keel structure, which comprises an integral bending forming middle right-angle plate 1 and side right-angle plates 2 and side flat plates 3 located on both sides thereof, the plate body of the side right-angle plate 2 adjacent to the middle right-angle plate 1 is used for wall setting, the two plate bodies of the middle right-angle plate 1 form a ceiling concave corner 6, the plate body of the side right-angle plate 2 away from the middle right-angle plate 1 is provided with a first clamping part for buckling with a second clamping part of an adjacent keel structure, and the side flat plate 3 is used for covering a decorative plate.
[0032] It should be noted that the keel structure has been widely applied to indoor ceiling modeling, especially to modeling ceiling, which is made of a frame of keel structure and a decorative plate of gypsum board. The ceiling concave corner 6 is usually built by a plurality of spliced keel structures against a wall body, and is used for hiding joints and providing space for installing equipment such as lamp strips. The right-angle plate is composed of two mutually perpendicular plate bodies.
[0033] Specifically, the keel structure for the ceiling concave corner comprises the middle right-angle plate 1, the side right-angle plate 2 and the side flat plate 3, the side right-angle plate 2 and the side flat plate 3 are arranged on both sides of the middle right-angle plate 1 and are formed by cold bending of a strip steel. Therefore, not only the bearing capacity of the keel structure is enhanced to improve the structural stability of the ceiling concave corner 6 built by a plurality of keel structures, but also the processing cost is saved to improve the construction cost of the ceiling concave corner 6 built by a plurality of keel structures.
[0034] In addition, the plate body of the side right-angle plate 2 adjacent to the middle right-angle plate 1 is a vertical plate of the side right-angle plate 2, the plate body away from the middle right-angle plate 1 is a horizontal plate of the side right-angle plate 2, the plate body of the middle right-angle plate 1 adjacent to the side right-angle plate 2 is a horizontal plate of the middle right-angle plate 1, and the plate body adjacent to the side flat plate 3 is a vertical plate of the middle right-angle plate 1. Among them, the vertical plate of the side right-angle plate 2 is used for wall setting, so that the horizontal plate of the middle right-angle plate 1 and the vertical plate of the middle right-angle plate 1 form the ceiling concave corner 6 between the wall body, and the horizontal plate of the side right-angle plate 2 is provided with a clamping part, which can be buckled on the clamping part of the adjacent keel structure to realize that the two adjacent keel structures are buckled and spliced together.
[0035] Therefore, in the process of the internal corner recessed furring ceiling, the number of the furring structures is determined according to the depth of the internal corner recess, the plate bodies of the side right-angle plates 2 of the adjacent two furring structures away from the middle right-angle plate 1 are buckled and spliced together through the two clamping parts, and the plate bodies adjacent to the middle right-angle plate 1 are arranged against the wall, so that the two plate bodies of the middle right-angle plate 1 of the plurality of furring structures and the wall jointly form the internal corner recess 6 of the ceiling, and the side flat plates 3 of the plurality of furring structures are externally covered with the decorative plate. Therefore, the plurality of furring structures are buckled and built into the internal corner recess 6 of the ceiling, compared with the pull-riveting splicing and building, not only the operation is simple, but also the building efficiency of the internal corner recess 6 of the ceiling can be improved, and the furring structures can be prevented from bearing excessive tension, so that the connection of the plurality of furring structures is more stable, and the structural stability of the internal corner recess 6 of the ceiling is improved.
[0036] It should be particularly pointed out that the vertical plate height of the side right-angle plate 2, the horizontal plate length and the vertical plate height of the middle right-angle plate 1 all need to be set to appropriate sizes according to the appearance design requirements of the ceiling of the user.
[0037] On the basis of the above embodiment, please refer to Figure 1 The first clamping part is provided as a dovetail 4 protruding downward, and the dovetail 4 is provided with a dovetail groove 5 matched with the dovetail 4 in the thickness direction, and the dovetail groove 5 is used for matching and adapting with the dovetail 4 of the adjacent furring structure.
[0038] Specifically, the horizontal plate of the side right-angle plate 2 is provided with a dovetail 4 protruding downward, and the dovetail 4 is provided with a notch with a certain depth in the thickness direction, and the notch is a dovetail groove 5 matched with the dovetail 4. In this way, the dovetail 4 on one furring structure can be buckled in the notch, i.e. the dovetail groove 5, of the dovetail 4 on the other furring structure adjacent thereto, and the furring structures are spliced in this way. On the one hand, the dovetail groove 5 and the dovetail 4 are buckled and connected, which can make the plurality of furring structures more closely spliced, and further improve the structural stability of the internal corner recess 6 of the ceiling. On the other hand, the plurality of furring structures with consistent structure sizes can be used to build the internal corner recess 6 of the ceiling, and the processing cost of the furring structure is further saved.
[0039] Preferably, please refer to Figure 1 The first clamping part is integrally formed with the plate body of the side right-angle plate 2 away from the middle right-angle plate 1. That is, the side right-angle plate 2 and the dovetail 4 thereon are integrally processed and formed, so that the dovetail 4 structure is more stable, and the adjacent two furring structures are firmly connected, which is beneficial to improve the structural stability of the internal corner recess 6 of the ceiling.
[0040] On the basis of the above embodiment, please refer to Figure 1The bending part between the side right-angle plate 2 and the middle right-angle plate 1 is a right angle. That is, the vertical plate of the side right-angle plate 2 and the horizontal plate of the middle right-angle plate 1 are perpendicular. On the one hand, when the vertical plate of the side right-angle plate 2 leans against the wall, the middle right-angle plate 1 can be closely attached to the wall, so that the middle right-angle plate 1 and the wall can form the ceiling corner recess 6 more conveniently, and the operator can operate conveniently. On the other hand, the structure is more compact, and the indoor top space is saved.
[0041] Based on the above embodiment, please refer to Figure 1 The plate body of the side right-angle plate 2 away from the middle right-angle plate 1 is located directly above the middle right-angle plate 1. That is, the horizontal plate of the side right-angle plate 2 extends on the side away from the wall. This not only facilitates the operator to fasten and splice, but also avoids a large gap between the middle right-angle plate 1 and the wall, which affects the modeling of the ceiling corner recess 6. It should be noted that before the ceiling corner recess 6 is built, the modeling of the ceiling corner recess 6 is achieved according to the structural size and shape of the middle right-angle plate 1 designed according to user requirements.
[0042] Based on the above embodiment, please refer to Figure 1 The bending part between the side flat plate 3 and the middle right-angle plate 1 is provided with a downwardly protruding flange 7. In this way, a plurality of keel structures can be aligned according to the flange 7 to improve the neatness and integrity of the entire keel ceiling corner. In addition, when the decorative plate is installed on the outside of the side flat plate 3, the flange 7 can correct the decorative plate to improve the flatness of the ceiling decorative plate.
[0043] Based on the above embodiment, please refer to Figure 1 The side flat plate 3 and the plate body of the middle right-angle plate 1 adjacent thereto are perpendicular. It can be understood that the vertical plate of the middle right-angle plate 1 is arranged along the height direction of the wall. Even if the side flat plate 3 is arranged horizontally, the flatness of the ceiling decorative plate can be further improved when the side flat plate 3 is perpendicular to the vertical plate of the middle right-angle plate 1.
[0044] Based on any of the above embodiments, please refer to Figures 2 to 4 The specific size of the ceiling corner recess keel structure is as follows: the length of the side flat plate 3 is about 30 mm, and the width is about 29.5 mm; the height of the plate body of the middle right-angle plate 1 adjacent to the side flat plate 3 is about 10 mm, and the width is about 29.5 mm; the length of the plate body of the middle right-angle plate 1 adjacent to the side right-angle plate 2 is about 10 mm, and the width is about 29.5 mm; the height of the plate body of the side right-angle plate 2 adjacent to the middle right-angle plate 1 is about 20 mm, and the width is about 29.5 mm; the length of the plate body of the side right-angle plate 2 away from the middle right-angle plate 1 is about 20 mm, and the width is about 29.5 mm; the maximum distance between the side flat plate 3 and the side right-angle plate 2 in the length direction is about 39.5 mm; and the maximum outer diameter of the dovetail joint 4 is about 4.5 mm.
[0045] The keel structure with the above size setting is stable in structure, small in deformation and strong in bearing capacity, and is favorable for improving the structural stability of the ceiling internal corner groove.
