Description

Technical Field

[0001] This utility model relates to the field of ceiling keel technology, and in particular to a ceiling keel component structure that is easy to connect. Background Technology

[0002] Modular integrated ceilings are increasingly used in modern home decoration because they have the following advantages: quick installation, rapid factory production, low worker requirements, and low labor costs.

[0003] However, in the existing prefabricated light steel keel ceiling, although the structure has been optimized compared with the traditional edge ceiling, there are still some inconveniences in the installation. Various intermediate keels cannot be quickly connected to the upper left or upper right at the same time. The connection structure is complicated and the connection efficiency is low. For high edge ceilings, the principle of first doing flat ceiling and then doing edge ceiling or using hanging panels can be used to solve the problem. Summary of the Invention

[0004] Therefore, in view of the above problems, this utility model proposes a ceiling keel component structure that is easy to connect.

[0005] This utility model is achieved through the following technical solution.

[0006] A ceiling keel includes a central keel body, the central keel body having a vertical slot and a horizontal slot extending longitudinally, the vertical slot allowing one end of the vertical keel to be inserted vertically for connection to the vertical keel, and the horizontal slot allowing one end of the horizontal keel to be inserted horizontally for connection to the horizontal keel.

[0007] As a further improvement of this utility model, the middle keel body is provided with a top edge that bends inward toward the vertical slot.

[0008] Based on the same concept, this utility model patent also discloses a ceiling keel assembly structure, including a horizontal keel, a vertical keel, and an intermediate keel body disposed between the horizontal keel and the vertical keel. The intermediate keel body has a vertical slot extending longitudinally, which allows one end of the vertical keel to be inserted vertically for connection. The intermediate keel body has a horizontal slot located below the vertical slot, which extends longitudinally and allows one end of the horizontal keel to be inserted horizontally. One end of the horizontal keel overlaps the horizontal slot, and the ratio of the portion of the horizontal keel inserted into the horizontal slot to the portion not inserted into the horizontal slot is adjustable.

[0009] As a further improvement of this utility model, the other end of the transverse keel is provided with a connecting plate for fixing to the wall by fasteners, and a bearing plate is provided on the lower side of the connecting plate, and the other end of the transverse keel overlaps the bearing plate.

[0010] As a further improvement of this utility model, a limiting plate is provided on the upper side of the connecting plate, and the limiting plate and the bearing plate have a distance adapted to the transverse keel. The limiting plate, the connecting plate and the bearing plate cooperate with each other to form the side wall keel.

[0011] As a further improvement of this utility model, a hoisting keel is provided at the upper end of the vertical keel, a keel hanger is provided on the hoisting keel, and a load-bearing structure for supporting the hoisting keel is provided on the keel hanger.

[0012] As a further improvement of this utility model, the keel bracket includes a top plate, a left side plate and a right side plate disposed on both sides of the top plate, the left side plate and the right side plate extending longitudinally, and the hoisting keel disposed between the left side plate and the right side plate.

[0013] As a further improvement of this utility model, the bearing structure includes a top abutment plate disposed on the left and right side plates. The top abutment plate extends along the hoisting keel and is inclined upward to abut against and support the hoisting keel.

[0014] As a further improvement of this utility model, the left and right side plates are provided with limiting plates located on the upper side of the abutment plate. The limiting plates are arranged opposite to the abutment plate to abut and limit the hoisting keel.

[0015] As a further improvement of this utility model, the top plate is provided with a hanger for connecting to the top of the wall, and the ratio of the portion of the hanger that is inserted into the top plate to the portion that is not inserted into the top plate is adjustable.

[0016] The beneficial effects of this utility model are:

[0017] 1. The intermediate keel of this utility model extends longitudinally and can connect the vertical keel and the horizontal keel at the same time, and can be quickly connected to the upper left or upper right. The structure is simple and convenient to connect and install.

[0018] 2. This utility model is equipped with a top abutment edge. After several vertical keels are inserted into the vertical slots, the top abutment edge abuts and restricts the vertical keels from detaching. Then, self-tapping screws or pins are installed to fix them in place, so as to facilitate installation.

[0019] 3. During the installation process, the horizontal keel only overlaps the horizontal slot. Accordingly, the ratio of the part inserted into the horizontal slot to the part not inserted into the horizontal slot is adjustable, which can control the gap between the other end of the horizontal keel and the wall surface, and thus control the gap between the other end of each horizontal keel and the wall to be uniform.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0031] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0032] refer to Figures 1 to 7 The present utility model embodiment discloses that:

[0033] A ceiling keel assembly structure, as shown in the figure, includes three horizontal keels 1, three vertical keels 2, and a central keel body 3 disposed between the horizontal keels 1 and the vertical keels 2. The central keel body 3 has a vertical slot 4 extending longitudinally, allowing one end of each vertical keel 2 to be inserted vertically for connection. The central keel body 3 has a horizontal slot 5 located below the vertical slot 4, extending longitudinally and allowing one end of each horizontal keel 1 to be inserted horizontally. One end of each horizontal keel 1 overlaps with the horizontal slot 5. The ratio of the portion of the keel 1 inserted into the horizontal slot 5 to the portion not inserted into the horizontal slot 5 is adjustable. In specific implementation, during installation, the vertical keel 2 is connected to the top of the wall, while the horizontal keel 1 is close to the wall surface. After the lower end of the vertical keel 2 is inserted into the vertical slot 4, it is then fixed and connected by self-tapping screws or rivets. The horizontal keel 1 only overlaps the horizontal slot 5. Accordingly, the ratio of the portion inserted into the horizontal slot 5 to the portion not inserted into the horizontal slot 5 is adjustable, which can control the gap between the other end of the horizontal keel 1 and the wall surface, thereby ensuring that the gap between the other end of each horizontal keel 1 and the wall is uniform.

[0034] During installation, the other end of the horizontal keel 1 needs to be connected to the wall surface to improve the overall strength of the edge ceiling. Based on this, the other end of the horizontal keel 1 is provided with a connecting plate 601 for fixing to the wall surface by fasteners (self-tapping screws, rivets, etc.). A bearing plate 602 is provided on the lower side of the connecting plate 601. The other end of the horizontal keel 1 overlaps on the bearing plate 602. The structure is simple and allows both ends of the horizontal keel 1 to be supported, thereby improving the overall strength of the edge ceiling.

[0035] During the installation of the connecting plate 601, workers need to lift it to prevent it and the supporting plate 602 from falling, resulting in high labor costs. Therefore, a limiting plate 603 is provided on the upper side of the connecting plate 601. The limiting plate 603 and the supporting plate 602 have a spacing adapted to the horizontal keel 1. The limiting plate 603, connecting plate 601, and supporting plate 602 cooperate to form the side wall keel 6, allowing the side wall keel 6 to be hung on the horizontal keel 1 via the limiting plate 603. During installation, the vertical keel 2 is installed first, then the side wall keel 6 is controlled to hang on the other end of the horizontal keel 1, and finally, the side wall keel 6 is fixed with fasteners. During installation, the limiting plate 603 can prevent the side wall keel 6 from falling, thereby saving labor costs.

[0036] Furthermore, in specific implementation, a hanging keel 7 is provided at the upper end of the vertical keel 2, that is, the upper end of the vertical keel 2 is connected to the hanging keel 7 by fasteners (self-tapping screws, rivets, etc.). A keel hanger 8 is provided on the hanging keel 7, which is used to connect to the top of the wall. The keel hanger 8 is provided with a load-bearing structure for supporting the hanging keel 7. The keel hanger 8 includes a top plate 801 and a left side plate 802 and a right side plate 803 provided on both sides of the top plate 801. The left side plate 802 and the right side plate 803 are arranged longitudinally. The hanging keel 7 is arranged between the left side plate 802 and the right side plate 803. During installation, the hanging keel 7 is controlled to pass between the left side plate 802 and the right side plate 803, and then supported by the load-bearing structure. The structure is simple and the connection is convenient.

[0037] Specifically, the supporting structure includes abutment pieces 804 disposed on the left and right side plates 803. The abutment pieces 804 extend along the hoisting keel 7 and are inclined upward to abut against and support the hoisting keel 7. That is, during installation, the hoisting keel 7 is controlled to pass between the left side plate 802 and the right side plate 803. At this time, the abutment pieces 804 are located under the hoisting keel 7 and can abut against the lower end face of the hoisting keel 7 to support the hoisting keel 7. The structure is simple, easy to process, and easy to connect.

[0038] Of course, after the hoisting keel 7 is inserted between the left side plate 802 and the right side plate 803, since the hoisting keel 7 is not fixed, it may vibrate (move up and down) relative to the left and right side plates 803 during the subsequent installation of other structures, thus affecting the installation effect. Based on this, the left and right side plates 803 are provided with limiting plates 805 located above the abutment plate 804. The limiting plates 805 and the abutment plate 804 are arranged opposite to each other to abut and limit the upper end face of the hoisting keel 7. That is, the limiting plates 805 and the abutment plate 804 are similarly extended along the hoisting keel 7, and the limiting plates 805 are inclined downwards. The limiting plates 805 and the abutment plate 804 cooperate to limit the vibration of the hoisting keel 7. It is worth mentioning that after the hoisting keel 7 is installed, the hoisting keel 7 and the keel hanger 8 can be fixed with fasteners.

[0039] It is also important to note that during the installation of the side joist assembly, the height of the horizontal joists 1 and the vertical joists 2 needs to be controlled to meet assembly requirements. Based on this, the top plate 801 is provided with a hanger 9 for connecting to the wall top. The ratio of the portion of the hanger 9 that is inserted into the top plate 801 to the portion that is not inserted into the top plate 801 is adjustable. Specifically, the hanger 9 is a screw rod. The upper end of the hanger 9 is inserted into the wall top to connect to the wall top, and the lower end of the hanger 9, located on both the upper and lower sides of the top plate 801, is provided with adjusting nuts to control the portion of the hanger 9 that is inserted into the top plate 801.

[0040] The vertical keel 2 is provided with inwardly curled edges 10. Specifically, the vertical keel 2 has a U-shaped structure, and the opposing walls on both sides are provided with inwardly curved edges 10, which makes the vertical keel 2 less prone to deformation in the vertical direction and more reliable.

[0041] The intermediate keel body 3 is provided with abutting edge 11 that bends inward toward the vertical slot 4. The abutting edge 11 can elastically deform. When the vertical keel 2 is inserted into the vertical slot 4, the abutting edge 11 abuts against the intermediate keel body 3, so that the side wall of the vertical keel 2 is always in contact with the inner wall of the vertical slot 4. After several vertical keels 2 are inserted into the vertical slot 4, the abutting edge 11 abuts against and restricts the vertical keels 2 from disengaging. Then, self-tapping screws or pins are installed uniformly to facilitate installation.

[0042] In addition, such as Figure 7 As shown, in another embodiment, the middle keel body 3 can also be set vertically. Of course, in this case, the vertical keel 2 and the horizontal keel 1 are both set horizontally and connected by fasteners to be installed around the vertical water pipe at the corner of the wall to form a vertical fence.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
