[0026] The prefabricated door panel connection system according to embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] Figure 1 This is a structural schematic diagram of the door leaf connecting component of the prefabricated door leaf connecting system provided in this embodiment of the present disclosure; Figure 2 This is a structural schematic diagram of the edge-finishing component of the prefabricated door leaf connection system provided in the embodiments of this disclosure; Figure 3 This is a schematic diagram of the structure of a prefabricated door leaf connection system after installation, provided in an embodiment of this disclosure;

[0029] Figure 4 yes Figure 3 An enlarged diagram of point A in the middle. (See below for reference.) Figures 1 to 4 Let's describe the assembled door panel connection system provided in the embodiments of this disclosure.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, the assembled door panel connection system provided in this embodiment includes: a door panel connecting member 100, including a vertically extending flat plate portion 101 located above and a recessed portion 102 located below with a first groove 110 opening downwards, the first groove having a left groove wall 103 and a right groove wall 104, and a sound-dampening strip 120 provided on the upper surface of the right side portion of the flat plate portion protruding from the right side portion of the flat plate portion; and an edge-finishing member 200, including a horizontal portion 201 and a middle vertical portion 202 extending vertically downwards from the middle of the horizontal portion. 02. A first edge portion 203 extending vertically downward from the left end of the horizontal portion and a second edge portion 204 extending vertically downward from the right end of the horizontal portion, a second groove is formed between the first edge portion and the middle vertical portion, and an insertion groove is formed between the second edge portion and the middle vertical portion, and the flat plate portion can be inserted into the insertion groove; a door leaf assembly, including a door leaf 302 and a hinge 301, the door leaf and the door leaf connecting member are connected by the hinge, and the door leaf abuts against the soundproof strip when closed; a first wall panel 402, one end of which is inserted into the first groove.

[0031] Existing technologies often involve long processing cycles for door panel connectors, requiring custom-made parts, lacking on-site thickness adjustment, incompatibility with prefabricated wall panels, and incurring high costs. The technical solution of this disclosure allows for the cutting and adjustment of the first wall panel according to the on-site wall thickness, enabling overall width adjustment of the door panel connector. Edge finishing components are then used to snap the door panel connector and the first wall panel together at their outer ends to complete the overall installation. This prefabricated door panel connector system features a simple connection structure, changes the traditional door panel connection and fixing method, and is suitable for widespread application.

[0032] like Figure 1 As shown, the left surface of the groove portion, i.e., the left surface of the left groove wall 103, and the left surface of the flat plate portion 101 are located on the same vertical plane. This design allows the door panel connecting member to be flush with the wall. In addition, the length of the flat plate portion is greater than the thickness of the door panel, so that the door panel will not protrude from the wall surface when closed, thereby increasing the aesthetic appearance of the door panel and its ease of use.

[0033] like Figure 3 As shown, the width of the first groove 100 is equal to the thickness of the first wall panel 402. The width of the first groove refers to the distance between the inner surfaces of the two groove walls of the first groove. The width of the first groove is equal to the thickness of the first wall panel, which allows the first wall panel to be smoothly inserted into the first groove and ensures a tight connection between the first groove and the first wall panel.

[0034] like Figure 3As shown, the prefabricated door panel connection system also includes a second wall panel 401 and a third wall panel 403, which are respectively connected to two horizontal surfaces of the wall 500. The edge trimming components include a first edge trimming component 210 and a second edge trimming component. The insertion groove of the first edge trimming component is inserted into the flat plate portion. The first edge portion of the first edge trimming component abuts against the upper surface of the second wall panel, and the middle vertical portion of the first edge trimming component abuts against the end of the second wall panel. The insertion groove of the left-right reversed second edge trimming component 220 is inserted into the other end of the first wall panel. The first edge portion of the second edge trimming component abuts against the lower surface of the third wall panel, and the middle vertical portion of the second edge trimming component abuts against the end of the third wall panel. The first edge portion of the edge trimming component abuts against the side wall panel on the side of the wall, which can press down the side wall panel, prevent the side wall panel from warping, and reduce the gap between the first edge portion and the side wall panel.

[0035] like Figure 2 As shown, the edge-finishing member includes an abutment portion 205 formed by bending vertically from the lower end of the first edge portion toward the vertical portion near the center. The design of the abutment portion can further enhance the effect of preventing warping and reducing gaps.

[0036] like Figure 3 and Figure 4 As shown, the width of the insertion groove is equal to the thickness of the flat plate, and the thickness of the flat plate is equal to the thickness of the first wall panel.

[0037] The groove width of the interlocking groove refers to the distance between the inner surfaces of the two groove walls. The groove width is equal to the thickness of the flat plate, allowing the flat plate to be smoothly inserted into the groove and ensuring a secure connection. The thickness of the flat plate is equal to the thickness of the first wall panel, allowing the groove width to match the thickness of the first wall panel, thus ensuring a smooth insertion and secure connection. The equal thickness of the flat plate and the first wall panel allows them to match the same groove width, enabling the use of identical edge-trimming components on both sides of the wall. This reduces the number of components in the prefabricated door panel connection system and simplifies the production process.

[0038] like Figure 1 As shown, the right side of the groove has a hollow structure containing a cavity 1041, which can reduce the amount of material used and reduce costs while ensuring strength.

[0039] like Figure 1As shown, the upper part of the right side of the groove is provided with a hole structure 1201. The hole structure includes a hollow cavity inside the groove and a connecting through hole connecting the hollow cavity to the outside. The soundproof strip includes a positioning part and a soundproof part connected as one piece. The positioning part is inserted into the hollow cavity through the connecting through hole. This hole design allows the soundproof strip to be easily embedded, thereby protecting the door leaf and providing a soundproofing effect.

[0040] In this embodiment, the tip of the sound-silencing part is elastic, thereby protecting the door and reducing the sound of closing the door. Figure 1 As shown, the positioning part is provided with a threaded structure, which makes it difficult for the sound-dampening strip to fall off from the hole structure.

[0041] When installing the prefabricated door panel connection system of this disclosure embodiment, the width of the second wall panel can be cut to the corresponding size according to the actual width of the wall on site. Then, one end of the processed and cut first wall panel is inserted into the first groove of the door panel connecting component to connect them into a whole. After that, the door panel connecting component and the first wall panel are fixed to the wall with nail guns and expanding foam. Then, the insertion groove of one edge trimming component is inserted into one end of the door panel connecting component, and the insertion groove of another edge trimming component is inserted into one end of the first wall panel. The edge trimming component is pressed against the side wall panel through the first edge of the edge trimming component.

[0042] This technical solution can divide the prefabricated door panel connection system into several standard modules, taking into account both convenient installation and standardized production. This allows for convenient modular transportation and flexible assembly, while avoiding material waste.

[0043] The door leaf connecting component of the prefabricated door leaf connecting system provided in this embodiment can connect to door leaf components. The flat plate portion above the door leaf connecting component can be inserted into the edge-finishing component to edge-finish and limit the door leaf connecting component. The groove portion below the door leaf connecting component can be inserted into the first wall panel to edge-finish and limit the first wall panel. Using this door leaf connecting component can simplify the installation process of the door leaf connecting system, improve installation efficiency, and, in conjunction with other components of the prefabricated door leaf connecting system, shorten the production and installation cycle of the door leaf connecting product and enhance the adaptability of the prefabricated door leaf connecting system. In addition, a sound-absorbing strip is provided on the groove portion to enhance the sound insulation effect, reduce noise when closing the door, and extend the service life of the door frame components.

[0044] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
