Description

Technical Field

[0001] This application relates to the field of building construction, and specifically belongs to a keel framework with a hanging cavity. Background Art

[0002] In the prior art, the dry hanging solution for decorative panels usually adopts the method of combining a keel framework with a leveling adapter. At the same time, the keel framework needs to be fixed to the wall, which greatly increases the occupied space of the partition wall, increases the material cost and construction cost. Inevitably, it also occupies the actual usable area of the original building.

[0003] Taking a 100-square-meter house as an example, the internal keel of the existing dry hanging system is 50 mm, and the decorative board is calculated with a thickness of 10 mm. Calculated according to the above installation method for a 100-square-meter house, the actual usable area is reduced by 2.4 square meters. Assuming that this set of rooms is in super first-tier cities such as Beijing, Shanghai, Guangzhou and Shenzhen, according to the local housing prices, the direct loss of 2.4 square meters for the house owner is about 500,000 yuan. Utility Model Content

[0004] The purpose of this utility model is to provide a keel framework with a hanging cavity. The decorative board can be dry hung on the keel framework through a back hanger. The distance between the decorative board and the keel framework is only 2 - 3 mm, which saves costs and solves the technical problem that the prefabricated dry hanging system occupies too much of the original indoor actual usable space.

[0005] To achieve the above purpose, this utility model adopts the following technical scheme:

[0006] A keel framework with a hanging cavity, the keel framework is a rectangular framework formed by splicing a plurality of horizontal keels and vertical keels. Both the horizontal keels and the vertical keels are hollow structures. It is characterized in that: the cavity of the vertical keel is filled with a magnesium-based material, the vertical keel is provided with hanging holes for clamping pre-embedded parts. The pre-embedded part includes a bottom plate, a side plate and a 7-shaped clamping plate arranged on the side plate. The 7-shaped clamping plate is clamped on the hole wall of the hanging hole. The lower edge of the bottom plate is lower than the lower edge of the hanging hole. The length of the 7-shaped clamping plate is adapted to the side lengths of both sides of the hanging hole. The space between the bottom plate and the inner wall of the vertical keel is the hanging space for the hanging part.

[0007] Further preferably, grooves are provided on the opposite sides of the adjacent left and right vertical keels. The grooves are strip-shaped structures extending along the length direction of the vertical keel.

[0008] Further, two layers of decorative panels are embedded in the grooves between the adjacent vertical keels.

[0009] Further, the vertical part of the 7-shaped clamping plate is not less than the wall thickness of the horizontal keel.

[0010] In addition, the hanging member is a back hanging member fixed on the decorative panel. The back hanging member is hung in the hanging space. The hanging member as a whole has an inverted U-shaped structure. One vertical part of the U-shaped structure is inserted into the reserved space between the bottom plate and the inner wall of the vertical keel, and the other vertical part is fixed to the decorative panel by a countersunk screw.

[0011] More preferably, the hanging hole is an inverted trapezoidal hole.

[0012] Compared with the prior art, the present utility model has the following characteristics and beneficial effects:

[0013] The present utility model solves the problems of messy construction site, long construction period, air pollution, etc. caused by traditional wet construction operations. There is no need for gluing during the construction process. Compared with the installation methods of decorative panels on the market, which mostly use back glue bonding, this system is more environmentally friendly and healthy.

[0014] By setting the internal keel in the wall, the present application can save the internal keel commonly used in the existing assembled dry-hanging systems on the market. The pre-opened trapezoidal holes on the keel can directly hang the decorative panel, and the internal gap is only 2-3 mm. While saving costs, it solves the technical problem that the assembled dry-hanging system occupies too much of the original indoor actual use space, greatly saves the indoor space consumed by the decoration for the house owner, improves the utilization rate of the house rental for the owner, and brings more economic benefits;

[0015] The installation efficiency of the present application is high. This system does not need to set up leveling keels and relies on the built-in keels of the wall panel. During the construction, only the back hanging member decorative panel needs to be positioned and fixed to be installed on the wall to complete the decorative finish.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the technical means, innovative features, achieved objectives and effects realized by the present utility model easy to understand, the present utility model will be further described below.

[0022] The embodiments described herein are specific specific implementation manners of the present utility model for explaining the concept of the present utility model, and are all explanatory and exemplary, and should not be construed as a limitation on the implementation manners of the present utility model and the scope of the present utility model. Except for the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the content disclosed in the claims and the specification of this application. These technical solutions include technical solutions that make any obvious substitutions and modifications to the embodiments described herein.

[0023] A keel frame with a hanging cavity, such as Figures 1 to 4 shown, the keel frame is a rectangular frame formed by splicing a plurality of horizontal keels 1 and vertical keels 2. Both the horizontal keels 1 and the vertical keels 2 are hollow structures. The cavity of the vertical keel 2 is filled with a magnesium-based material 3. The vertical keel 2 is provided with hanging holes 7 for clamping embedded parts 6. The embedded part 6 includes a bottom plate 61, a side plate 62 and a 7-shaped clamping plate 63 provided on the side plate 62. The 7-shaped clamping plate 63 is clamped on the hole wall of the hanging hole 7. The space between the bottom plate 61 and the inner wall of the vertical keel 2 is the hanging space for the hanging part 10.

[0024] Grooves 4 are provided on the opposite sides of the left and right adjacent vertical keels 2. The grooves 4 are strip-shaped structures extending longitudinally along the length of the vertical keel 2. Between adjacent vertical keels 2, two layers of decorative panels 5 are embedded in the grooves 4. The combination of the keel frame and the decorative panel 5 is equivalent to the partition wall of a traditional building, which plays a role in dividing the indoor space, but definitely does not play a main load-bearing role. It is equivalent to setting a dry system on the partition wall to minimize the floor space occupied by the decorative dry hanging structure.

[0025] The vertical part of the 7-shaped clamping plate 63 is not less than the wall thickness of the horizontal keel 1. The hanging part 10 is a back hanging part fixed to the decorative plate 9 by a countersunk screw 8. The back hanging part is hung in the hanging space. The hanging hole 7 is an inverted trapezoidal hole. The back hanging part is an L-shaped hanging part with a hook part. The 7-shaped clamping plate 63 is clamped on the hole wall of the hanging hole 7. The projected area of the bottom plate 61 should be larger than the projected area of the hanging hole 7, and the bottom of the bottom plate 61 should be far lower than the lower edge of the hanging hole 7. The hanging part of the hanging part 10 is in the space between the bottom plate 61 and the inner wall of the keel. The hanging hole 7 should be wider at the top and narrower at the bottom to facilitate the insertion of the hanging part of the back hanging part into the hanging space. More preferably, the hanging hole 7 is an inverted isosceles trapezoidal hole. The horizontal intersection angle of the 7-shaped clamping plates 63 on both sides is the same as the horizontal intersection angle of the two waist sides of the inverted isosceles trapezoidal hole.

[0026] The construction steps of this application are as follows:

[0027] 1. Pre-drilled holes in the keel: The system requires pre-drilling trapezoidal hanging holes in the light steel vertical keels of the wall. The trapezoidal hole spacing is set according to the characteristics of different hanging decorative panels. Usually, the vertical hole spacing is 450 mm. The trapezoidal holes need to be opened on a customized cold-bending keel machine.

[0028] 2. Embedded parts: After the wall frame is completed, the frame needs to be filled with magnesium-based materials. Before filling the materials, the production of the embedded parts needs to be completed by hot-injected rubber. The embedded parts are placed inside the trapezoidal opening (hanging hole 7) to ensure that there is a hanging cavity inside the trapezoidal hanging hole. The embedded parts are fixed inside the vertical keel through the combined action of the 7-shaped clamping plate 63 and the magnesium-based materials.

[0029] 3. Back-hanging connecting parts: The hanging part 10 (back-hanging connecting part) is made by bending galvanized steel plates or by die-casting aluminum alloys. It is used as a fixing part behind the decorative panel. During installation, the position needs to be marked in advance on the invisible side of the decorative panel and corresponding to the trapezoidal opening position of the wall panel. This part is connected to the decorative panel by screws.

[0030] 4. Installation: After the back-hanging parts are installed and fixed, the worker sucks up the decorative panel with a suction cup, aligns it with the keel position, inserts it into the trapezoidal hole, and slides it down to complete the installation.

[0031] The parts not involved in the present utility model are the same as the prior art or can be implemented by using the prior art.

[0032] The above shows and describes the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments. Moreover, without departing from the spirit or basic features of the present utility model, the present utility model can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0033] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for 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 embodiments that can be understood by those skilled in the art.
