[0018] In order to make the technical means, innovative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0019] The embodiments described herein are specific embodiments of the present invention, which are used to illustrate the concept of the present invention, are explanatory and exemplary, and should not be interpreted as limiting the embodiments of the present invention and the scope of the present invention. In addition to the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the claims and the contents disclosed in the specification of this application, including technical solutions that adopt any obvious replacement and modification of the embodiments described herein.

[0020] like Figures 1 to 3As shown, this embodiment provides a dry hanging node, including a keel 1 and a back hanging part 2. The keel 1 is a hollow rod-shaped keel, and the keel 1 is filled with a magnesium-based material 3. The keel 1 is provided with a hanging hole 4, and the hanging hole 4 is provided with an embedded part 6. The space between the bottom plate of the embedded part 6 and the inner wall of the keel 1 is the hanging space of the back hanging part 2. One side of the back hanging part 2 is fixed to the decorative plate 5, and the other side is hung in the hanging space. The embedded part 6 includes a bottom plate 61, a side plate 62 arranged along the outer edge of the bottom plate 61, and a 7-shaped clamping plate 63 arranged on the side plate 62. The 7-shaped clamping plate 63 is clamped on the hole wall of the hanging hole 4, the lower edge of the bottom plate 61 is lower than the lower edge of the hanging hole 4, and the length of the 7-shaped clamping plate 63 is adapted to the length of the two sides of the hanging hole 4.

[0021] Based on the above further improvements, in this embodiment, the embedded part 6 is an integrally formed plastic structure.

[0022] Based on the above further improvements, in this embodiment, the bottom plate 61 is a special-shaped structure that is wide at the top and narrow at the bottom, including an upper rectangular structure 64, a middle inverted isosceles trapezoidal structure 65 and a lower rectangular structure 66. The bottom side of the upper rectangular structure 64 is equal in length to the top side of the middle inverted isosceles trapezoidal structure 65, and the top side of the lower rectangular structure 66 is equal in length to the bottom side of the middle inverted isosceles trapezoidal structure 65.

[0023] Based on the above further improvement, in this embodiment, the 7-type clamping plate 63 is arranged on both side waist edges of the middle inverted isosceles trapezoidal structure 65 and is equal in length to the waist edges.

[0024] Based on the above further improvements, in this embodiment, the back hanging member 2 is an inverted U-shaped structure, and the right side panel is longer than the left side panel, and the left side panel is inserted into the space between the lower rectangular structure 66 and the inner wall of the keel 1.

[0025] Based on the above further improvement, the above dry hanging node is directly used in the assembled wall panel dry hanging system of magnesium wing composite board. The dry hanging system includes a keel frame and a decorative panel hung on the keel frame. The keel frame is a rectangular frame formed by splicing a number of horizontal keels and vertical keels. Both the horizontal keel and the vertical keel are hollow structures. The cavity of the vertical keel is filled with magnesium-based materials. The vertical keel is provided with a hanging hole for clamping the embedded parts. The embedded parts include a bottom plate, a side plate and a 7-type clamping plate arranged on the side plate. The 7-type clamping plate is clamped on the hole wall of the hanging hole. The space between the bottom plate and the inner wall of the vertical keel is the hanging space of the hanging part; the hanging part is a back hanging part fixed on the decorative panel by countersunk screws, and the back hanging part is hung in the hanging space. The opposite sides of the left and right adjacent vertical keels are provided with grooves, and the grooves are strip structures arranged along the length direction of the vertical keel.

[0026] Two layers of decorative panels are embedded in the grooves between adjacent vertical purlins. The combination of the purlin frame and the decorative panels is equivalent to the partition wall of traditional buildings, which plays the role of dividing the interior space, but it does not play the main load-bearing role. It is equivalent to setting up a dry system on the partition wall to minimize the space occupied by the decorative dry hanging structure.

[0027] The vertical part of the 7-type pallet is not less than the wall thickness of the horizontal keel. The embedded parts are of a left-right symmetrical structure. The side panels are arranged along the edge of the bottom plate. The 7-type pallet is arranged on the left and right side panels. The embedded parts are an integrally formed structure made of plastic. The 7-type pallet is slightly inclined to the outside relative to its body to facilitate the entire embedded part to be fixed on the hanging hole, the bottom plate, the side panels and the 7-type pallet arranged on the side panels.

[0028] The 7-type card is fixed on the hole wall of the hanging hole 7. The projection area of ​​the bottom plate should be larger than the projection area of ​​the hanging hole, and the bottom of the bottom plate should be much lower than the lower edge of the hanging hole. The hanging piece is hung in the space between the bottom plate and the inner wall of the keel. The hanging hole should be wide at the top and narrow at the bottom. More preferably, the hanging hole 7 is an inverted isosceles trapezoidal hole. The horizontal intersection angle of the 7-type card on the left and right sides is the same as the horizontal intersection angle of the waist edges on both sides of the inverted isosceles trapezoidal hole.

[0029] The application construction steps are as follows:

[0030] 1. Pre-opening of keel holes: This system requires pre-opening of trapezoidal hanging holes on the light steel vertical keel of the wall. The trapezoidal hole spacing is set according to the characteristics of different hanging decorative panels. Usually the vertical hole spacing is 450mm. The trapezoidal holes need to be opened on a customized cold-bent keel machine.

[0031] 2. Embedded parts: After the wall frame is completed, magnesium-based materials need to be filled in the frame. Before filling the material, the embedded parts need to be produced by hot-injecting rubber and embedded in the trapezoidal opening (hanging hole) to ensure that there is a hanging cavity in the trapezoidal hanging hole.

[0032] 3. Back-hanging connector: The hanging part (back-hanging connector or back-hanging part) is made of bent galvanized steel plate or made of aluminum alloy mold. It is used as a fixing part behind the decorative panel. When installing, it is necessary to lay out and position the decorative panel in advance on the invisible surface, corresponding to the trapezoidal opening position of the wall panel. This part is connected to the decorative panel with screws.

[0033] 4. Installation: After the back hanging parts are installed and fixed, the worker sucks up the decorative plate with a suction cup, inserts it into the trapezoidal hole at the keel position, and slides down to complete the installation.

[0034] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art.

[0035] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
