Description

Technical Field

[0001] The utility model relates to an integrated suspended ceiling, in particular to an integrated suspended ceiling secondary keel structure and an integrated suspended ceiling using the structure. Background Art

[0002] At present, most users' kitchens generally use aluminum gusset plate integrated ceilings, and the aluminum gusset plates are assembled through the keel structure installed on the ceiling.

[0003] For example, the Chinese utility model patent application number 202420115652.9 discloses a ceiling keel structure, which includes a load-bearing main keel, an assembly hook, an assembly secondary keel and an assembly hanging piece. An assembly opening is opened through one end of the assembly hook. The load-bearing main keel is fixedly arranged on the inner side of the load-bearing slot, the assembly secondary keel is arranged at the bottom of the load-bearing main keel, and the assembly hanging piece is bent and hung on the outer side of the load-bearing main keel.

[0004] Range hoods are essential appliances for people to absorb oil fumes during daily cooking. Traditional range hoods are usually fixed directly to the solid wall with ordinary hooks. In recent years, products with fans built into the ceiling have become popular. However, most users' kitchens use integrated ceilings made of aluminum gusset plates. The size of range hood fans is generally larger than the 300mm*30mm size of the gusset plates, and cannot be placed directly through the gusset plate holes. Therefore, it may be necessary to cut off and connect the secondary keels. The design and production sizes of secondary keels by different manufacturers are slightly different, but the cross-sectional shape is basically an inverted triangle.

[0005] Existing ordinary keel connectors require users to use an electric drill to drill holes again for installation. A hand drill may not be able to penetrate, and high precision is required, which is not convenient for service technicians to adjust and install on site. Utility Model Content

[0006] The technical problem to be solved by the present invention is to address the deficiencies in the above-mentioned prior art and to provide an integrated ceiling sub-keel structure that can adapt to keels of different sizes and cross-sections without the need for additional holes.

[0007] The second technical problem to be solved by the present invention is to provide an integrated ceiling using the above-mentioned secondary keel structure.

[0008] The technical solution adopted by the present invention to solve the first technical problem is: an integrated ceiling sub-keel structure, comprising a first sub-keel segment, a second sub-keel segment, and a connecting assembly connecting the first sub-keel segment and the second sub-keel segment, characterized in that:

[0010] By setting up a connecting assembly, the first support member and the second support member respectively support the two sections of secondary purlins, and the first support member and the second support member are respectively cooperated with the first bolt to realize the independent up and down adjustment of the two support members, so as to match the connection of triangular purlins from different manufacturers with different sizes or cross-sections (compared to other methods, mixed connection of triangular purlins from different manufacturers can be achieved), without the need for additional drilling, reducing the operating difficulty of service technicians, and improving installation speed and convenience.

[0011] In order to limit the first support member and the second support member and achieve double-thread interlocking with the first bolt, further solving the problem of loosening and falling, the connecting assembly also includes a first limiting nut and a second limiting nut. The first limiting nut and the second limiting nut are both threadedly connected to the first bolt and can move along the axis of the first bolt. The first limiting nut is limited below the first support member, and the second limiting nut is limited above the second support member.

[0012] In order to achieve uniform and stable adjustment, the connecting assembly also includes a second bolt, which also passes through the first support member and the second support member and is threadedly engaged with the first support member and the second support member respectively.

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0027] See also Figure 1 , an integrated ceiling, mainly used as a ceiling in the kitchen, which is installed above the kitchen cabinets, and the stove is under the cabinets.

[0028] The integrated ceiling includes a main keel 100 and a secondary keel 300. Both the main keel 100 and the secondary keel 300 are arranged horizontally, preferably horizontally. The main keel 100 is longer than the secondary keel 300. The secondary keel 300 intersects the main keel 100 and, in this embodiment, is perpendicular to the main keel 100. The secondary keel 300 is located below and fixed to the main keel 100. The main keel 100 is fixed to the floor slab at the top of the kitchen.

[0029] Since the main keel 100 and the secondary keel 300 each have at least two and are arranged in an intersecting manner, the main keel 100 and the secondary keel 300 constitute a plurality of separated spaces, in which the gusset plates 200 can be arranged. The secondary keel 300 is a commonly used triangular keel, and the gusset plates 200 are clamped at the bottom of the secondary keel 300.

[0030] When installing an electrical appliance, such as the fan housing of a ceiling range hood, the gusset plate 200 at the installation location is first removed. Because the fan housing is larger than the gusset plate 200, a sub-keel 300 needs to be cut, separating it into a first sub-keel segment 1, which remains fixed in place, and a second sub-keel segment 2, which needs to be removed. After removing the second sub-keel segment 2, the fan housing can pass through the space between the two adjacent gusset plates 200. After installation is complete, the removed second sub-keel segment 2 needs to be connected to the remaining first sub-keel segment 1, and the gusset plate 200 is then reinstalled.

[0031] During the process of installing and restoring the severed secondary keel 300 , the connection is performed through the following connection assembly of the present invention.

[0032] See also Figures 2 to 5 The connecting assembly includes a first bolt 31, a second bolt 32, a first support member 33 and a second support member 34. The first bolt 31 is arranged close to the first sub-keel segment 1, and the second bolt 32 is arranged close to the second sub-keel segment 2. The two ends of the first support member 33 are respectively supported on the inner sides of the first sub-keel segment 1 and the second sub-keel segment 2, and the two ends of the second support member 34 are respectively supported on the inner sides of the first sub-keel segment 1 and the second sub-keel segment 2. The first support member 33 and the second support member 34 are arranged at intervals up and down. The first bolt 31 and the second bolt 32 pass through the first support member 33 and the second support member 34 and are respectively threaded together. The first support member 33 can move longitudinally relative to the first bolt 31 and the second bolt 32, and the second support member 34 can move longitudinally relative to the first bolt 31 and the second bolt 32.

[0033] The connection assembly includes a first limiting nut 35, a second limiting nut 36, a third limiting nut 37, and a fourth limiting nut 38. The first limiting nut 35 and the second limiting nut 36 are both threadedly connected to the first bolt 31 and can move along the axis of the first bolt 31. The first limiting nut 35 is positioned below the first support member 33, while the second limiting nut 36 is positioned above the second support member 34. The third limiting nut 37 and the fourth limiting nut 38 are both threadedly connected to the second bolt 32 and can move along the axis of the second bolt 32. The third limiting nut 37 is positioned below the first support member 33, while the fourth limiting nut 38 is positioned above the second support member 34.

[0034] The first auxiliary keel segment 1 includes a first top portion 11, and first and second clamping portions 12, 13, respectively, disposed on opposite sides of the first top portion 11. The first and second clamping portions 12, 13 extend obliquely downwardly toward each other. One end of the first support member 33, located on the inner side of the first auxiliary keel segment 1, abuts upward against the first top portion 11. The second support member 34, located on the inner side of the first auxiliary keel segment 1, abuts downwardly between the first and second clamping portions 12, 13, thereby clamping the first support member 33. The second auxiliary keel segment 2 includes a second top portion 21, and third and fourth clamping portions 22, 23, respectively, disposed on opposite sides of the second top portion 21. The third and fourth clamping portions 22, 23 extend obliquely downwardly toward each other. One end of the first support member 33, located on the inner side of the second auxiliary keel segment 2, abuts upward against the second top portion 21. The second support member 34, located on the inner side of the second auxiliary keel segment 2, abuts downwardly between the third and fourth clamping portions 22, 23, thereby clamping the second support member 34. The four sides of the gusset plate 200 are connected to the secondary keel by being inserted between the two clamping parts of the corresponding secondary keel.

[0035] Thus, by utilizing the inverted triangular structure on the inner side of the keel, and then using the first bolt 231 and the second adjusting member 32 to screw up and down the first support member 33 and the second support member 34, the two supports are adapted to keels of different cross-sectional sizes. This allows the connection of triangular keels from different manufacturers with different sizes or cross-sections to be matched (compared to other methods, it can also achieve mixed connection of triangular keels from different manufacturers). No additional holes are required, which reduces the operational difficulty for service technicians and improves installation speed and convenience. Each limit nut is used to stably define the position of each support member and can be used in conjunction with the corresponding bolt to achieve double-thread locking, further preventing loosening.

[0036] The installation order of the connecting assembly connecting two keels is:

[0037] 1) First, screw the first bolt 31 and the second bolt 32 into the first support member 33 from top to bottom;

[0038] 2) Screw the first limiting nut 35 and the second limiting nut 36 onto the first bolt 31 from bottom to top, and screw the third limiting nut 37 and the fourth limiting nut 38 onto the second bolt 32 from bottom to top;

[0039] 3) Connect the second support member 34 to the first bolt 31 and the second bolt 32;

[0040] 4) Insert one end of the first support member 33 and the second support member 34 into the inner side of the first secondary keel segment 1, and adjust the relative positions of the first limiting nut 35 and the second limiting nut 36 so that the corresponding sides of the first support member 33 and the second support member 34 are clamped to the inner side of the first secondary keel segment;

[0041] 5) Insert the other ends of the first support member 33 and the second support member 34 into the inner side of the second secondary keel segment 2, and adjust the relative positions of the third limiting nut 37 and the fourth limiting nut 38 so that the corresponding sides of the first support member 33 and the second support member 34 are clamped to the inner side of the second secondary keel segment 2 to complete the connection.
