Description

MULTI-DIRECTIONAL ADJUSTABLE SUSPENDED CEILING PANEL SUSPENSION STRUCTURE TECHNICAL FIELD [0001] The present application relates to the technical field of buildings and particularly to a multi-directional adjustable suspended ceiling panel suspension structure. BACKGROUND[0002] For most of suspended ceilings of houses in the prior art, a suspending rod with a threaded structure is designed. The upper end of the suspending rod is fixedly disposed on a ceiling, and the lower end of the suspending rod is connected and suspended with two suspension nuts; next, a suspended ceiling keel sleeves the lower end of the suspending rod and is clamped by the two suspension nuts, and the positions of the suspension nuts are adjusted so that the suspended ceiling keel at the upper end is located on the same horizontal plane; and then, a suspended ceiling is mounted on the suspended ceiling keel. Therefore, a suspended ceiling suspension structure in the prior art may only meet a demand on horizontal mounting of a suspended ceiling. However, with the development of decoration, it is often encountered that the suspended ceiling needs to be mounted obliquely, (that is, the suspended ceiling is an inclined suspended ceiling), at the moment, construction achieved by suspending the suspended ceiling in the prior art will become very troublesome. Moreover, if the ceiling is inclined (such as a ceiling of a loft), it is inconvenient to achieve vertical mounting of the suspending rod even if a horizontal suspended ceiling is mounted, and thus, difficulty in construction is caused.

[0047] As shown in FIG. 1, FIG. 2 and FIG. 3, a multi-directional adjustable suspended ceiling panel suspension structure, includes: [0048] an upper suspending seat 1, configured to be connected to a supporting body located above suspended ceiling panels 39; [0049] a suspending rod assembly, having an adjustable suspension height and a top mounted on the upper suspending seat 1 in a swing way; [0050] a lower suspending seat 4, connected to the bottom of the suspending rod assembly; [0051] a keel, mounted on the lower suspending seat 4 at an adjustable inclination angle; and [0052] the suspension ceiling panels 39, suspended on the keel. [0053] The present application is suitable for mounting suspended ceiling panels 39 with various inclination angles. After the suspended ceiling panels 39 are mounted, smooth transition at joints of all the suspended ceiling panels 39 is achieved, and thus, a plurality of folded surfaces which are not all parallel may be formed and are similar to a plurality of cutting surfaces of diamond. [0054] An upper suspending seat 1 is a supporting body of the suspended ceiling panels and is used for bearing the overall weight of the suspended ceiling panel suspension structure. As shown in FIG. 1, the supporting body may be a ceiling (that is, a structural panel) 36 of a building or other supporting structures on the building. [0055] Height adjustability of a suspending rod assembly means that one end of the suspending rod assembly is fixed together with the supporting body, and the other end of the suspending rod assembly is variable in height relative to the supporting body, that is, a lower suspending seat 4 is adjustable in height relative to the supporting body. The suspending rod assembly may swing relative to an upper suspending seat 1 in a vertical surface so as to adapt to different suspension angles of the suspended ceiling panels 39. [0056] As shown in FIG. 1, a length direction of the suspending rod assembly is a Y axis, a direction perpendicular to the Y axis and parallel to a principal plane is an X axis, and a direction forming a plane perpendicular to the X axis and the Y axis is a Z axis. The X axis and the Y axis form an XY plane, the Y axis and the Z axis form a YZ plane, and the X axis and the Z axis form an XZ plane. A ceiling panel 39 of the present application may at least simultaneously achieve the orientation adjustment of the following spatial dimensions: [0057] (1) the suspending rod assembly is adjustable in its length direction; [0058] (2) the suspending rod assembly may swing within the XY plane; [0059] (3) the keel may swing within the XY plane, and the keel and the suspending rod assembly are swung independently. id="p-60" id="p-60" id="p-60"

The upper suspending seat 1 includes a top plate 5 of an upper seat portion and two side plates 6 of the upper seat portion, the two side plates 6 of the upper seat portion are connected two ends of the top plate of the upper seat portion and are mutually parallel. In a use state, the two side plates 6 of the upper seat portion are located below the top plate 5 of the upper seat portion, and the top plate of the upper seat portion is fixedly connected with the supporting body through an anchor 37. [0063] Arc-shaped through holes 9 are provided in the two side plates 6 of the upper seat portion, and the arc-shaped through holes 9 in the two side plates 6 of the upper seat portion have the same radius and are aligned with each other. In one of the embodiments, the upper suspending seat 1 is of a stainless steel structure. [0064] The suspending rod assembly may swing around the upper horizontal hinged shaft 7, and lock a rotation angle of the suspending rod assembly by a first fastener. As shown in FIG. 1, the first fastener may adopt the upper connecting pin 10. [0065] As shown in FIG. 1, FIG. 2 and FIG. 3, the suspending rod assembly includes: [0066] a suspending rod 2, having a top mounted on the upper suspending seat 1 in a swing way; [0067] an adapter, nested inside the suspending rod 2; and [0068] a suspending screw 17, having two ends respectively connected to the adapter and the lower suspending seat 4, wherein at least one of the adapter and the lower suspending seat 4 is adjustable in position relative to the suspending screw 17, so that the suspension height is changed. [0069] In one of the embodiments, the suspending rod assembly is made of an aluminum alloy.

A lower end of the suspending screw 17 is disposed on the suspending plate 15 of the lower suspending seat portion in a penetrating manner. A third nut 24 is threadedly connected to the suspending screw 17. The third nut 24 is matched with the suspending block 23 to claim the suspending plate 15 of the lower suspending seat portion, so as to fix the suspending screw 17 and the lower suspending seat 4 together. [0077] During use, the height of the lower suspending seat 4 is adjusted by loosening the first nut 20 and the second nut 21, so as to adjust the height of suspended ceiling panels 39 to a desired position. [0078] There is a rotation stopping plate 18 fixedly connected with the suspending rod 2 to prevent the lower suspending seat 4 from rotating. An elbow 25 is disposed at a lower end of the rotation stopping plate 18. In one of implementations, the elbow 25 is sleeved on the suspending screw 17 and clamped by the third nut 24 in matching with the suspending block 23, so as to be fixed together with the suspending plate 15 of the lower suspending seat portion.
