Description

Technical Field

[0001] The invention belongs to the technical field of decoration and renovation, and in particular relates to an integrated ceiling structure. Background Art

[0002] In existing integrated ceiling structures, ceiling panels are generally installed using a combination of secondary and primary purlins. The primary purlin is fixed to the ceiling using a combination of screws and expansion screws. The secondary purlin is fixed to and located below the primary purlin. The aluminum beams in the patio structure are evenly installed vertically and horizontally on the ceiling of the room by cooperating with the secondary purlin. When the aluminum beam is installed parallel to the secondary purlin, it is directly installed on the secondary purlin by cooperating with the clips provided on the aluminum beam. When the aluminum beam is installed perpendicular to the secondary purlin, it needs to be fixed with fasteners or other devices. The fixing method when the aluminum beam and the secondary purlin are connected vertically is relatively complex, making it difficult to install quickly, and thus, the installation efficiency is low. Summary of the Invention

[0003] The present invention aims to solve the following technical problem: the fixing method for vertically connecting the aluminum beam and the auxiliary keel is relatively complicated, which makes it difficult to install quickly and thus results in low installation efficiency.

[0004] The invention provides an integrated suspended ceiling structure.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The integrated ceiling structure includes a main keel, a secondary keel, a cross connector, and a gusset plate. The main keel is a long strip structure, and the two ends of the main keel are fixed to the wall. The secondary keel is a short strip structure, and the end of the secondary keel abuts against the outer wall of the main keel. The cross connector is arranged on the top of the main keel and the secondary keel and fixedly connects the main keel and the secondary keel. The main keel and the secondary keel are made of two layers of steel plates, and the middle of the two layers of steel plates are fixedly connected by bolts. After the two sides of the upper layer of steel plate are bent upward, the upper edge is bent inward to form The folded edge, the two sides of the lower layer of steel plate are bent downward to form an acute angle, and then bent inward to form a hook edge, and the hook edges on both sides are offset against each other. The cross connecting member includes a central plate portion and an extended plate portion around it. Connecting ears extend on both sides of the extended plate portion, and bolt holes are provided on the connecting ears. The connecting ears and the main keel / secondary keel are connected by bolts. The gusset plate is a rectangular structure, and the four sides of the gusset plate are folded upward to form a card edge. When the gusset plate is installed, the card edge of the gusset plate is clamped between the two hook edges of the main keel / secondary keel.

[0007] As a preferred technical solution, snap-on ears extend from both sides of the extension plate portion, and the cross-section of the snap-on ears is in a "ㄣ" shape. The snap-on ears are clamped under the folded edge of the main keel / secondary keel.

[0008] As a preferred technical solution, a lifting hole is provided in the middle of the central plate portion.

[0009] As a preferred technical solution, the hook angle edge is in a V-shaped structure.

[0010] After adopting the above technical solution, the present invention has the following advantages:

[0011] The integrated ceiling structure of the present invention integrates aluminum beams and secondary purlins, enabling quick installation and high installation efficiency. After the primary purlins are uniformly installed, the primary and secondary purlins are quickly installed using a cross connector. The secondary purlins and the primary purlins form an inspection port, panel, or electrical appliance installation location. When the inspection port, panel, or electrical appliance installation location needs to be changed, the secondary purlins can be easily removed by disassembling the cross connector. The primary and secondary purlins can then be reconnected using the cross connector according to the installation location. When installing the gusset plate, its clamping edge is clamped between the two hooked corner edges of the primary or secondary purlin. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1-3 As shown, the integrated ceiling structure includes a main keel 1, a secondary keel 2, a cross connector 3, a hanger 5, and a gusset plate 6.

[0019] The main purlin 1 is a long strip-shaped structure, with both ends of the main purlin 1 fixed to the wall. The secondary purlin 2 is a short strip-shaped structure, with its ends abutting against the outer wall of the main purlin 1. The cross connector 3 is installed on the top of the main purlin 1 and the secondary purlin 2 and fixedly connects the main purlin 1 and the secondary purlin 2.

[0020] The main purlin 1 and secondary purlin 2 are made of two layers of steel plates, fixed in place by bolts. The upper layer of steel plate has its sides bent upward, and its upper edges are then bent inward to form a folded edge 4. The lower layer of steel plate has its sides bent downward to form an acute angle, and then bent inward to form a hooked edge 7. The hooked edges 7 on both sides abut against each other. The hooked edges 7 have a V-shaped structure.

[0021] The cross connector 3 is integrally stamped and comprises a central rectangular plate 31 and surrounding extension plates 32. A hanging hole 311 is provided in the center of the central plate 31 for mounting a hanger rod 5, the top of which is mounted on the ceiling.

[0022] Connecting ears 33 extend from either side of the extension plate 32. These ears are provided with bolt holes and are bolted to the primary purlin 1 / secondary purlin 2. When the cross connector 3 is stamped, the ears 33 and the extension plate 32 are located on the same horizontal plane. When the cross connector 3 is in use, the ears 33 are bent downward until they abut against the outer walls of the primary purlin 1 / secondary purlin 2. This arrangement ensures that even if there are manufacturing errors between the cross connector 3, primary purlin 1, and secondary purlin 2, the spacing between the ears 33 on either side of the extension plate 32 can accommodate the width of the primary purlin 1 / secondary purlin 2.

[0023] Snap-fit ​​ears 34 extend from both sides of the extension plate 32 . The cross section of the snap-fit ​​ears 34 is in a “U” shape. The snap-fit ​​ears 34 are snapped under the folded edge 4 of the main keel 1 / secondary keel 2 .

[0024] In this embodiment, the cross connector 3 connects one main keel 1 and two secondary keels 2, and the two secondary keels 2 are arranged on both sides of the main keel 1. It is understandable that the cross connector 3 can also connect one main keel 1 and one secondary keel 2.

[0025] The gusset plate 6 is a rectangular structure, and the four sides of the gusset plate 6 are folded upward to form a clamping edge 8. When the gusset plate 6 is installed, the clamping edge 8 of the gusset plate 6 is clamped between the two hook angle edges 7 of the main keel 1 or the secondary keel 2.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0027] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
