Description

Technical Field

[0001] This utility model belongs to the field of doors and windows, and particularly relates to a dry-hanging door. Background Technology

[0002] In existing technologies, dry-hung doors typically consist of only a single, undivided, large cavity. This significantly reduces the overall sound insulation performance of the door. Similarly, the single air layer results in high heat transfer efficiency and poor thermal insulation. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a dry-hanging door that can solve the aforementioned technical issues.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A dry-hanging door includes an inner core frame and door panels connected to both sides of the inner core frame in the thickness direction via hook assemblies. Side panels are also provided at the circumferential edge of the inner core frame. The side panels and the door panels together enclose a sealed inner cavity space.

[0005] Furthermore, a reinforcing plate is fixed on each side of the inner core skeleton in the thickness direction. Each reinforcing plate, the corresponding door panel, and the side panel form the inner cavity space. At least a portion of the hook assembly is fixed to the reinforcing plate, and the remaining portion is fixed to the door panel.

[0006] Furthermore, an internal space is formed between the side plate and the two reinforcing plates.

[0007] Furthermore, a reinforcing beam is also connected to the side plate to divide the interior space into several sub-spaces.

[0008] Furthermore, the internal space and the internal cavity space are independent of each other and not connected.

[0009] Furthermore, an inner cavity sealing strip is provided between the side panel and the door panel to seal the inner cavity space.

[0010] Furthermore, the inner cavity sealing strip includes a sealing lip inserted between the side panel and the door panel, and a buffer portion connected to the sealing lip.

[0011] Furthermore, the side plate is connected to the inner core skeleton in a T-shape, and the side plate at least partially protrudes from the thickness direction of the inner core skeleton.

[0012] Furthermore, one side of the inner core skeleton in the width direction is connected to the door frame via a hinged structure.

[0013] Furthermore, a fireproof sealing strip is provided between the door frame and the door panel, and the fireproof sealing strip is inserted into either the door frame or the door panel.

[0014] Compared with existing technologies, the advantages of this application are as follows: A self-contained, enclosed functional unit is constructed through the tight enclosure of the side panels and the door panel. This design effectively solves the problems of poor heat insulation and sound insulation in traditional dry-hung doors. The sealed cavity significantly improves the sound insulation performance of the door. Simultaneously, the sealed environment eliminates air convection, ensuring the long-term stability of the insulation material and greatly enhancing the door's heat insulation performance.

[0021] Example 1

[0022] like Figure 1 As shown, a dry-hanging door includes an inner core frame 1 and door panels 2 connected to both sides of the inner core frame 1 in the thickness direction via hook assemblies 9. Side panels 3 are also provided around the circumferential edge of the inner core frame 1. Each door panel 2, side panel 3, and inner core frame 1 together form a sealed inner cavity space S. Further, as... Figure 4 As shown, the side plate 3 is connected to the inner core skeleton 1 in a T-shape, and the side plate 3 protrudes at least partially from the thickness direction of the inner core skeleton 1.

[0023] To facilitate installation, the inner core frame 1 can be fabricated first during the manufacturing of the aforementioned dry-hanging door, while the door panel 2 can be assembled on-site. Furthermore, the inner core frame 1 and the door panel 2 adopt a glue-free dry-hanging structure, which can be detached and replaced at will.

[0024] In addition, such as Figures 1-4As shown, a reinforcing plate 4 is fixed on each of the two sides of the inner core frame 1 in the thickness direction. Each reinforcing plate 4, the corresponding door panel 2, and the side panel 3 form an inner cavity space. At least a portion of the hook assembly 9 is fixed to the reinforcing plate 4, and the remaining portion is fixed to the door panel 2. The hook assembly 9 includes a hooking part 91 disposed on the reinforcing plate 4, and a hooking part 92 disposed on the inner side of the door panel 2 and adapted to the hooking part 91. During installation, the hooking part 92 can be hung vertically from top to bottom, or directly snapped onto the hooking part 91 in the horizontal direction, thereby achieving convenient connection and reliable fixation between the door panel 2 and the reinforcing plate 4. In actual installation, depending on the on-site construction conditions, the door panel 2 can be hung vertically from top to bottom, or directly snapped into in the horizontal direction.

[0025] Specifically, the mounting portion 91 can be a mounting groove or mounting rod provided on the reinforcing plate 4, while the hook portion 92 is a mounting connector or mounting hole that mates with the mounting groove or mounting rod. By placing the main load-bearing part of the hook assembly 9 on the reinforcing plate 4, not only is the strength of the connection point improved, but wear on the inner core frame 1 caused by frequent assembly and disassembly is also avoided. The reinforcing plate 4 is preferably made of metal and is fixed to the inner core frame 1 by bolts or welding, further enhancing the stability and durability of the overall structure.

[0026] like Figure 1 and Figure 4 As shown, an internal space P is formed between the side panel 3 and the two reinforcing plates 4. A dividing reinforcing beam 5, which divides the internal space P into several sub-spaces, is also connected to the side panel 3. Simultaneously, the internal space P and the inner cavity space S are independent and not interconnected. Specifically, the multiple sealed sub-spaces divided by the dividing reinforcing beam 5 effectively block and slow down the heat conduction path, thereby significantly improving the overall thermal insulation performance of the door. In terms of sound insulation, this independent sealed sub-space structure, in conjunction with the aforementioned inner cavity space S, constitutes a sound insulation system.

[0027] like Figures 1-2 As shown, an inner cavity sealing strip 6 is provided between the side panel 3 and the door panel 2 to seal the inner cavity space S. The inner cavity sealing strip 6 includes a sealing lip 61 inserted between the side panel 3 and the door panel 2, and a buffer portion 62 connected to the sealing lip 61. The sealing lip 61 is usually designed as a flexible sheet or strip structure. After the door panel 2 is installed in place, the sealing lip 61 is squeezed by the edges of the side panel 3 and the door panel 2, producing a slight elastic deformation, thereby tightly filling the assembly gap between the two and preventing external moisture, dust and other contaminants from entering the vital inner cavity space S.

[0028] Example 2

[0029] The structure and principle of this embodiment are basically the same as those of Embodiment 1. The difference lies in that, for the dry-hanging door of Embodiment 1, this embodiment describes other features of a dry-hanging door.

[0030] One side of the inner core frame 1 in the width direction is connected to the door leaf frame 7 by a hinge structure. A fireproof sealing strip 8 is also provided between the door leaf frame 7 and the door panel 2. The fireproof sealing strip 8 is inserted into either the door leaf frame 7 or the door panel 2.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
