Figure 11 For a structural schematic diagram of the door frame profile provided in an embodiment of the present invention, please refer to [link / reference]. Figure 9-11 This embodiment provides a hidden door frame installation structure. The hidden door frame installation structure of this embodiment includes a non-removable template 1, a hidden door frame 2, and a decorative layer 3. The non-removable template 1 and the hidden door frame 2 are connected by corner brackets 4.

[0098] The concealed door frame 2 includes a vertical frame and a horizontal frame located at the top of the vertical frame. The vertical frame and the horizontal frame are connected by connectors. Both the vertical frame and the horizontal frame include door frame profiles. The door frame profiles include a first sidewall 21, a second sidewall 22, and a third sidewall 23 connected in sequence. The first sidewall 21, the second sidewall 22, and the third sidewall 23 form an opening for installing the door frame square material 5. The side of the first sidewall 21 facing away from the opening has a first groove 211, and the side of the second sidewall 22 facing away from the opening has a second groove 221. The connectors include a first L-shaped connector located in the first groove 211 of the vertical frame and the horizontal frame, and a second L-shaped connector located in the second groove 221 of the vertical frame and the horizontal frame.

[0099] The end of the third sidewall 23 has a first flange 231 and a second flange 232 extending in a direction away from the third sidewall 23. A first groove 233 is formed between the first flange 231 and the second flange 232. The second flange 232 is located outside the first flange 231, and the length of the second flange 232 is greater than the length of the first flange 231.

[0100] The decorative layer 3 includes a gypsum board 32 and a paint 33. The gypsum board 32 is installed on the non-removable template 1, and the paint 33 covers the gypsum board 32 and the first flange 231 and the second flange 232 of the invisible door frame 2.

[0101] Please see Figure 4 , Figure 10 and Figure 11 In this embodiment, the non-removable template 1 has a third slot. The corner bracket 4 in this embodiment includes a first corner bracket 41 and a second corner bracket 42. The first corner bracket 41 includes a first connecting block and a first connecting plate connected to the first connecting block. The first connecting block is located in one of the second slots 221. The first connecting plate is fixedly connected to the structural column or lintel of the non-removable template 1. The second corner bracket 42 includes a second connecting block and a second connecting plate connected to the second connecting block. The second connecting block is located in the third slot of the non-removable template 1. The second connecting plate is fixedly connected to the third side wall 23 of the hidden door frame 2.

[0102] In this embodiment, the gypsum board 32 is laid from the wall surface on one side of the non-removable template 1 to the first flange 231 of the third sidewall 23 of the invisible door frame 2. The thickness of the gypsum board 32 is flush with the first flange 231. By setting the first flange 231 and the second flange 232 extending in a direction away from the third sidewall 23 at the end of the third sidewall 23, a first groove 233 is formed between the first flange 232 and the second flange 232. This allows the joint paper tape set at the edge of the gypsum board 32 and the third sidewall 23 of the invisible door frame 2 to be fed into the first groove 233. Then, the gap is filled with joint filler, which can prevent cracks at the edge of the gypsum board 32 and the invisible door frame 2. The second flange 232 is located outside the first flange 231. The length of the second flange 232 is greater than the length of the first flange 231. For example, in this embodiment, the second flange 232 of the invisible door frame 2 is used as a leveling layer for putty, which facilitates the smoothing of the putty. After the paint 33 is applied, the second flange 232 is completely hidden.

[0103] For example, in this embodiment, the second flange 232 of the third sidewall 23 of the concealed door frame 2 is a slope. In this embodiment, the paint 33 completely covers the second flange 232 of the third sidewall 23 of the concealed door frame, and the concealed door frame 2 becomes an integral part of the wall.

[0104] Unlike Embodiment 4, the door leaf 6 made using the concealed door frame installation structure of this embodiment has an opening direction that faces away from the decorative layer 3.

[0105] The concealed door frame installation structure of this embodiment can be combined with different forms of skirting board construction. For example, in the concealed door frame installation structure of this embodiment, the concealed door frame 2 can make a recessed skirting board near the ground by giving up the thickness of a layer of plasterboard 32.

[0106] Example 6:

[0107] Please see Figure 9-11 This embodiment provides a method for constructing a concealed door frame, applied to the concealed door frame installation structure described in Embodiment 5. The method includes:

[0108] S201. Splice the horizontal frame and the two vertical frames arranged opposite each other, fix the two sides of the first L-shaped connector to the first slot 211 of the vertical frame and the horizontal frame respectively, and fix the two sides of the second L-shaped connector to the second slot 221 of the vertical frame and the horizontal frame respectively, so that the vertical frame and the horizontal frame are spliced ​​together to form the invisible door frame 2.

[0109] Specifically, in this embodiment, there are two second slots 221, and two adjacent second slots 221 are arranged in parallel. The vertical and horizontal frames of the hidden door frame 2 are connected by two second connectors located in the second slots 221 and a first connector located in the first slot 211. The two second connectors and one first connector are all L-shaped corner connectors, which are assembled at 45° angles on the outer and rear sides of the hidden door frame 2. The two vertical frames and one horizontal frame are assembled at 45° angles to form the complete three sides of the hidden door frame 2, which enhances the connection strength of the three sides of the hidden door frame 2 and the overall structural strength of the hidden door frame 2.

[0110] S202. Install the invisible door frame 2 onto the non-removable template 1 using the corner bracket 4;

[0111] Specifically, please refer to Figure 4 , Figure 10 and Figure 11 In this embodiment, the non-removable template 1 has a third slot. The corner bracket 4 in this embodiment includes a first corner bracket 41 and a second corner bracket 42. The first corner bracket 41 includes a first connecting block and a first connecting plate connected to the first connecting block. The first connecting block is located in one of the second slots 221. The first connecting plate is fixedly connected to the structural column or lintel of the non-removable template 1. The second corner bracket 42 includes a second connecting block and a second connecting plate connected to the second connecting block. The second connecting block is located in the third slot of the non-removable template 1. The second connecting plate is fixedly connected to the third side wall 23 of the hidden door frame 2.

[0112] S203. Install the gypsum board 32 on the non-removable template 1, the gypsum board 32 covers the third side wall 23, and apply paint 33 to the gypsum board 32, wherein the paint 33 covers the first groove 233 and the second flange 232.

[0113] Specifically, plasterboard 32 is laid from one side of the wall of the non-removable template 1 to the first flange 231 of the third side wall 23 of the invisible door frame 2. The thickness of plasterboard 32 is flush with the first flange 231. Joint tape is attached to the plasterboard 32 and the first flange 231. The edge of the joint tape is inserted into the first groove 233. The first groove 233 is filled with joint filler. Then, putty is applied to the plasterboard 32, covering the first groove 233 and the second flange 232. This method can prevent the paint 33 at the edge of the plasterboard and the door frame from cracking. Moreover, the end of the second flange 232 of the invisible door frame 2 is a putty leveling layer, which can improve construction efficiency. After the paint 33 is painted, the second flange 232 is completely hidden.

[0114] Furthermore, the second flange 232 has an inclined surface that slopes towards the first flange 231. After attaching the seam tape to the plasterboard 32 and the first flange 231, and tucking the edge of the seam tape into the first groove 233, the method further includes: using the inclined surface of the second flange 232 as a leveling layer to completely cover the second flange 232 of the third sidewall 23 with paint 33. In this embodiment, by providing an inclined surface on the second flange 232 that slopes towards the first flange 231, the inclined surface of the second flange 232 can be used as a leveling layer when applying putty to the plasterboard 32, which can improve the leveling efficiency. After painting with paint 33, the second flange 232 is completely hidden.

[0115] In the construction method of the hidden door frame in this embodiment, the hidden door frame 2 can be made into a recessed skirting board near the ground by giving up the thickness of a layer of gypsum board 32.

[0116] In the above embodiments of the present invention, the concealed door frame 2 is installed before the wall surface is completed. The concealed door frame 2 is pre-installed on the door frame opening in the wall, or fixed to the structural column and lintel of the non-removable template 1 through the second groove 221 and the corner bracket 4. The pre-installed concealed door frame 2 is both the base structure of the wall structure and the stop structure of the door leaf 6. The concealed door frame 2, which performs two structural functions at the same time, structurally connects the door frame and the wall into one, forming a structural component with overall load-bearing capacity. This allows for free structural dimensions and accurate positioning of the door frame, and ensures a firm and durable connection with the opening structure.

[0117] In the structural function of the concealed door frame 2, the door leaf stop 51 is located between the wall decoration layer 3 and the door leaf 6, bearing the force of opening and closing the door leaf 6. Through the strong structural connection between the concealed door frame 2 and the structural columns and lintels of the non-removable template 1, the force is transferred to the overall load-bearing structural members. As an extension of the wall base structure, the overall load-bearing structure of the concealed door frame 2 separates the wall decoration layer 3 attached to the concealed door frame 2 from the force transmission path of the load-bearing members. The spaced-apart wall decoration layer 3 has a stable structure, avoiding problems such as surface cracking and peeling caused by frequent opening and closing of the door leaf 6 during later use.

[0118] The concealed door frame 2 integrates the installation requirements and conditions of door frame functional accessories such as concealed hinges and door frame airtight sealing strips 7. The metal wall of the concealed door frame 2 serves as a structural reinforcement plate for fixing the concealed hinges to the door frame opening or the structural column of the non-removable template 1, enhancing the overall structural strength of the concealed hinge connection between the frame and the door leaf 6, and preventing the door leaf 6 from sagging and obstructing opening and closing due to hinge loosening. The door leaf stop 51, which is matched with the door frame airtight sealing strip 7, blocks the through gap between the door leaf 6 and the concealed door frame 2. Through structural design and accessory integration, the overall installation performance of the concealed door frame 2 and the door leaf 6 in terms of comprehensive functions such as heat preservation, airtightness, sound insulation, light blocking, and smoke prevention is improved.

[0119] The finished surface of the door leaf 6 installed in the hidden door frame 2 can be made using the same process as the wall decoration layer 3, extending the process of the decoration layer 3 from the hidden door frame 2 to the door leaf 6, presenting an overall seamless effect where the wall decoration layer 3, the hidden door frame 2, and the door leaf 6 are indistinguishable. Similarly, the finished surface of the door leaf 6 installed in the hidden door frame 2 can also be made using a different process than the wall decoration layer 3, presenting a combined effect of the wall and the door leaf 6.

[0120] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. 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 the present invention.
