Description

Technical Field

[0001] This utility model relates to the field of door installation technology, specifically a door frame installation structure that can adapt to walls of different thicknesses. Background Technology

[0002] A wooden door structure generally includes the door leaf, door frame, door trim, and hinges. The door frame and door trim together form the outer frame of the wooden door, installed in the wall opening, ensuring the dimensional stability of the door and serving a decorative purpose. The door frame and door trim are two separate components; the door trim, also known as the door casing trim, solves the problem of finishing the door frame during installation. The door leaf is installed to the door frame via hinges. The back of the door frame is glued (such as wood glue or silicone sealant) and installed perpendicular to the thickness of the wall opening. The door trim is inlaid into a groove in the door frame, glued to the back, and installed parallel to the door leaf.

[0003] Existing patent ZL201220018822.9 discloses "A Door Frame Structure," in which the wooden door frame is L-shaped, with the long side being the decorative part and the short side being the inlay part. It employs a splicing structure of wooden panels, with splicing methods including flat splicing and mortise and tenon splicing. The wooden panels are spliced ​​using a combination of adhesive and nails, with wood glue being used as the adhesive. Existing patent ZL202120860694.1 discloses "A Paint-Free Multi-Layer Solid Wood Bending Door Frame," which provides a door frame structure in the form of a flat bending design.

[0004] The aforementioned structure typically uses three sets of door frame components and six sets of door trim components to assemble the wooden door frame. The door frame components include door stop strips, and the door width matches the wall thickness by adjusting the depth of the door trim within the door frame groove. However, the current standard thickness for load-bearing walls is 240mm, the standard thickness for non-load-bearing walls is 120mm, and the minimum wall thickness is 90mm. Because wall thicknesses are often non-standard and have dimensional deviations during actual installation, the existing door frame structure has poor installation flexibility for different wall thicknesses. Utility Model Content

The first side plate and the third side plate are parallel to each other, and the first side plate and the third side plate are respectively connected to two first mounting arms. The first side plate and the third side plate are also respectively connected to the wall.

[0009] Preferably, the length L of both the first side plate and the third side plate is greater than the thickness of the first mounting arm, so that the first side plate and the third side plate extend outside the mounting gap. The outer wall of the third side plate is provided with a first mounting groove, and a first anti-collision rubber strip for abutting against the door body is installed in the first mounting groove.

[0010] Preferably, the connector and the first end of the wall form a receiving cavity, which is filled with sound insulation cotton or heat insulation cotton.

[0011] The outer surfaces of both the door frame and the connector are provided with a first decorative layer, which is wood veneer, PVC film or melamine paper.

[0012] Preferably, the connector is connected to the door frame by a toothed plate and / or bonded and / or bolted; the connector is connected to the wall by a toothed plate and / or bonded and / or bolted.

[0013] Preferably, the corners of the door frame and the connector are rounded.

[0014] Preferably, the connector is T-shaped, and the T-shaped connector includes a first side arm and a second side arm. The two ends of the first side arm are respectively connected to the slots of the two first mounting arms. One end of the second side arm is connected to the first side arm, and the other end is connected to a door stop strip. The two ends of the door stop strip are respectively connected to the outer surfaces of the two first mounting arms to seal the installation gap.

[0015] Preferably, the door stop strip is provided with a second mounting groove at one end near the door body, and a second anti-collision rubber strip for abutting against the door body is installed in the second mounting groove;

[0016] The installation gap is filled with sound insulation cotton or heat insulation cotton; the outer surface of the door frame and the door stop strip are provided with a second decorative layer, which is wood veneer, PVC film or melamine paper.

[0017] Preferably, the door stop strip is bonded and fixed to the door frame; the corners of both the door frame and the door stop strip are rounded.

[0018] Preferably, the connector is made of aluminum alloy.

[0019] This utility model discloses a door frame installation structure that can adapt to walls of different thicknesses, and has the following beneficial effects: By setting up L-shaped door frames and connectors, two L-shaped door frames are connected at the corners of the wall, so that there is an installation gap between the first mounting arms of the two door frames. The connectors located in the installation gap are connected to the first mounting arms on both sides, ensuring the dimensional stability of the door frame installation structure.

[0031] like Figures 1 to 5 As shown, a door frame installation structure adaptable to walls of different thicknesses includes a door frame installation component 1. Two door frame installation components 1 are respectively provided on both sides of the door body 2, and one side of the door body 2 is hinged to one of the door frame installation components 1.

[0032] The door frame mounting assembly 1 includes a door frame 11 and a connector 12. Two door frames 11 are installed at two corners of the same end of the wall 3. The L-shaped door frame 11 includes a first mounting arm 111 and a second mounting arm 112. The two second mounting arms 112 are respectively attached to the inner and outer sides of the wall 3. The two first mounting arms 111 are attached to the same end of the wall 3, and there is an installation gap 113 between the two first mounting arms 111. The connector 12 is disposed in the installation gap 113, and the two ends of the connector 12 are respectively connected to the two first mounting arms 111.

[0033] The door frame 11 installation structure of this solution includes two sets of door frame installation components 1. The wall 3 has a door opening. The two sets of door frame installation components 1 are installed on the wall 3 on both sides of the wall opening. The door 2 is located between the two door frame installation components 1. The door 2 is hinged to one of the door frame installation components 1 to achieve opening and closing.

[0034] The door frame installation assembly 1 includes an L-shaped door frame 11 and connectors 12. Two L-shaped door frames 11 are connected at the corners of the wall 3, creating an installation gap 113 between the first mounting arms 111 of the two door frames 11. The connectors 12, located within the installation gap 113, connect to the first mounting arms 111 on both sides, ensuring the dimensional stability of the door frame installation structure. By pre-setting various connectors 12 of different lengths, even if the installation gap 113 between the two door frames 11 differs for wall 3 of different thicknesses, the corresponding length of connector 12 can be installed, providing high adaptability. Furthermore, this solution directly integrates the door frame 11 and the door trim into a single component, with no seams on the surface, a smooth shape, and retains the finishing and decorative functions of traditional door trims. Only six sets of standard components are needed to assemble the wooden door frame, simplifying the wooden door structure. The standard components facilitate manufacturing and installation.

[0035] Furthermore, the connector 12 is C-shaped, and the C-shaped connector 12 includes a first side plate 121, a second side plate 122, and a third side plate 123. The two ends of the second side plate 122 are bent to the same side to form the first side plate 121 and the third side plate 123, respectively. The first side plate 121 and the third side plate 123 are parallel to each other, and the first side plate 121 and the third side plate 123 are respectively connected to the two first mounting arms 111. The first side plate 121 and the third side plate 123 are also respectively connected to the wall 3.

[0036] like Figures 1 to 3As shown, in the first embodiment of this solution, the two door frames 11 are connected to each other by C-shaped connectors 12. Both the door frames 11 and the connectors 12 can be made of wood-plastic composite material, resulting in a relatively simple overall structure and ensuring the dimensional stability of the door frame 11 installation structure. The connectors 12 on both sides of the door body 2 are arranged in opposite directions.

[0037] In this embodiment, the door frame installation structure can be adapted to walls of different thicknesses. One installation process is as follows: 1) Measure the thickness of the wall 3 and apply a moisture-proof layer to the installation location of the wall 3 to give the wall 3 a better moisture-proof effect; 2) Assemble and fix the door frame 11 and the connector 12 with adhesive; 3) Connect the assembled door frame 11 (and connector 12) to the wall 3; 4) Install the door leaf on the door frame 11 with hinges, leaving a gap of about 3mm.

[0038] Furthermore, the length L of both the first side plate 121 and the third side plate 123 is greater than the thickness of the first mounting arm 111, so that the first side plate 121 and the third side plate 123 extend to the outside of the mounting gap 113. The outer wall of the third side plate 123 is provided with a first mounting groove 1231, and a first anti-collision rubber strip 1232 for abutting against the door body 2 is installed in the first mounting groove 1231.

[0039] Because the first side plate 121 and the third side plate 123 are relatively long, the connector 12 extends to the outside of the installation gap 113, so that the third side plate 123 has enough space to set the first mounting groove 1231. The first anti-collision rubber strip 1232 in the first mounting groove 1231 can produce a certain elastic deformation when subjected to external impact to offset part of the impact force. When the door is closed, the door body 2 will contact the first anti-collision rubber strip 1232 of the door stop 4, which plays a certain buffering role and reduces collision damage.

[0040] Furthermore, the connector 12 and the first end of the wall 3 form a receiving cavity 13, which is filled with sound insulation cotton or heat insulation cotton.

[0041] The outer surfaces of both the door frame 11 and the connector 12 are provided with a first decorative layer, which is wood veneer, PVC film or melamine paper.

[0042] The connector 12 and the wall 3 form an upper and lower opening cavity 13. The cavity 13 can be filled with sound insulation cotton or heat insulation cotton to improve the heat insulation or sound insulation performance of the door 2 and the entire door frame 11 installation structure. In actual installation, the heat insulation cotton can also be replaced with heat insulation felt, sponge or other foam materials, or the sound insulation cotton can be replaced with other damping and sound-absorbing materials.

[0043] The first decorative layer on the outer surface of the door frame 11 and the connector 12 uses the same decorative material and processing technology. The decorative material can be selected from wood veneer, PVC film or melamine paper, etc., according to the requirements, and the processing technology can be paint or paint-free process.

[0044] Furthermore, the connector 12 is connected to the door frame 11 by a toothed plate and / or bonded and / or bolted; the connector 12 is connected to the wall 3 by a toothed plate and / or bonded and / or bolted.

[0045] The connection between the door frame 11 and the connector 12, and the connection between the connector 12 and the wall 3, can be secured with adhesive, with the adhesive joint thickness not exceeding 0.5mm. Wood glue or silicone sealant can be used, or other adhesives that meet the required connection strength. Alternatively, the door frame 11 and the connector 12, or the connector 12 and the wall 3, can also be connected by bolts or toothed plates. For bolt connections, self-tapping screws are driven obliquely into the end of the connector 12 from the cavity side to secure the door frame 11 and the connector 12. For toothed plate connections, toothed plates are nailed into the first end of the wall 3; the size and number of toothed plates are determined according to installation requirements, and the connector 12 is then secured using the toothed plates. Of course, the above components can also be connected simultaneously using toothed plates, adhesive, and bolts.

[0046] Furthermore, the corners of both the door frame 11 and the connector 12 are rounded. The exposed corners of the door frame 11 and the connector 12 are rounded, ensuring higher safety during installation, transportation, and use. The radius of the rounded corners during installation is 3mm.

[0047] Furthermore, the connector 12 is T-shaped, and the T-shaped connector 12 includes a first side arm 124 and a second side arm 125. The two ends of the first side arm 124 are respectively connected to the slots 1111 of the two first mounting arms 111. One end of the second side arm 125 is connected to the first side arm 124, and the other end is connected to a door stop strip 4. The two ends of the door stop strip 4 are respectively connected to the outer surfaces of the two first mounting arms 111 to seal the mounting gap 113.

[0048] like Figures 4 to 5As shown, in the second embodiment of this solution, the door frame 11 is connected to the T-shaped connector 12 and the door stop 4. The base material of the door stop 4 is usually made of multi-layer wood. The connector 12 includes an integrally formed first side arm 124 and a second side arm 125. The first side arm 124 extends into the two first mounting arms 111 on both sides, and the connection is relatively stable. The end of the second side arm 125 extends into the door stop 4, which provides a certain fixing effect for the door stop 4. In addition, both ends of the door stop 4 are connected to the door frame 11, which provides a second layer of fixing. Therefore, the structure of this embodiment can ensure a very stable connection between the door stop 4, the connector 12, and the door frame 11. At the same time, the door stop 4 covers the installation gap 113, which has a good decorative effect. The second side arm 125 is usually connected to the middle of the door stop strip 4 and is perpendicular to the direction of the first end of the wall 3. The first side arm 124 is usually connected to the middle of the first mounting arm 111 and can be installed in a position slightly to the left or right of the middle. It is sufficient to achieve the connection and fixation of the door stop strip 4, the connector 12 and the door frame 11.

[0049] In this embodiment, the door frame installation structure adaptable to walls of different thicknesses can be installed in one of the following ways: 1) Measure the thickness of the wall 3 and apply a moisture-proof layer to the installation location of the wall 3 to improve its moisture-proof effect; 2) Securely fasten the two door frames 11 at the two corners of the wall 3 with adhesive; 3) Embed the T-shaped connector 12 into the groove 1111 of the first mounting arm 111 (one or more T-shaped connectors 12 can be installed along the height direction of the door frame 11); 4) The second side arm 125 of the T-shaped connector 12 is inserted into the groove of the door stop strip 4, and the gap between the door stop strip 4 and the door frame 11 is fixed with adhesive; 5) Install the door 2 on one of the door frames 11 using a hinge, leaving a gap of about 3mm.

[0050] Furthermore, the door stop strip 4 is provided with a second mounting groove 41 at one end near the door body 2, and a second anti-collision rubber strip 42 for abutting against the door body 2 is installed in the second mounting groove 41;

[0051] The installation gap 113 is filled with sound insulation cotton or heat insulation cotton; the outer surfaces of the door frame 11 and the door stop strip 4 are provided with a second decorative layer, which is wood veneer, PVC film or melamine paper.

[0052] A second mounting groove 41 is provided at one end of the door stop 4 near the door body 2. A second anti-collision rubber strip 42 is provided in the second mounting groove 41. The second anti-collision rubber strip 42 can undergo elastic deformation and can offset part of the impact force when it is impacted. When the door is closed, the door body 2 will come into contact with the second anti-collision rubber strip 42 of the door stop 4, which plays a certain role in buffering and reducing collision damage. The sealed installation gap 113 is also filled with sound insulation cotton or heat insulation cotton, which plays a good role in heat insulation or sound insulation.

[0053] The finishing materials and application processes used for the second finishing layer on the outer surfaces of the door frame 11 and the door stop strip 4 are the same to maintain the integrity of the entire door frame 11 structure and enhance its aesthetics. Specific finishing materials used during installation can include wood veneer, PVC film, or melamine paper, selected appropriately for different scenarios. The processing technology for the second finishing layer can employ either paint or paint-free processes.

[0054] Furthermore, the door stop strip 4 is bonded and fixed to the door frame 11; the corners of both the door frame 11 and the door stop strip 4 are rounded. Since the door stop strip 4 is rarely subjected to external pulling forces after installation, the door frame 11 and the door stop strip 4 can be bonded and fixed together using adhesive. In actual installation, the adhesive joint thickness is usually no more than 0.5mm, and wood glue or silicone sealant can be used, or other adhesives that meet the required connection strength can be selected as needed.

[0055] Both the door frame 11 and the door stop strip 4 have rounded corners with a radius of about 3mm, which makes them safer to install and transport, and less likely to scratch installers or users.

[0056] Furthermore, the connector 12 is made of aluminum alloy. The T-shaped connector 12 is made of aluminum alloy, which is lightweight and has suitable strength, ensuring a long service life for door frame installation structures that can adapt to walls of varying thicknesses. Typically, the thickness of the T-shaped connector 12 is approximately 3-3.5 mm, the length of the first side arm 124 is approximately 60 mm, the length of the second side arm 125 is approximately 20 mm, and the overall height is 100 mm. The ends of the first side arm 124 extending into the first mounting arm 111 and the ends of the second side arm 125 extending into the door stop strip 4 can both be designed with rounded corners.

[0057] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
