Description

Technical Field

[0001] This utility model relates to the field of door structure technology, and in particular to a novel structural wooden door. Background Technology

[0002] As an important component of buildings, wooden doors not only serve to separate spaces and ensure security and privacy, but their thermal insulation performance also directly impacts the overall energy consumption of the building. In cold northern regions, it is necessary to improve the thermal insulation performance of entrance doors to reduce energy consumption for building heating. Currently, the most common entrance doors on the market are mainly divided into two categories: metal security doors and wooden doors. Although metal doors are strong and have good anti-theft performance, the thermal conductivity of metal is extremely high, which easily leads to a large amount of indoor heat being quickly conducted to the outside through the door. In contrast, the thermal conductivity of wood is much lower than that of metal. Wooden doors made of heavy solid wood or solid wood composite structures can effectively slow down the heat conduction rate, reducing indoor heat loss to a certain extent and playing a basic role in thermal insulation and energy saving.

[0003] However, wooden doors will expand and contract to a certain extent under changes in humidity. When wooden doors absorb water, they expand, making them difficult to close and easily causing deformation or squeezing of the door frame. When the humidity is low, the wooden door will shrink, creating gaps between it and the door frame, making it easy for cold air from the outside to penetrate. Utility Model Content

[0004] In view of the problems mentioned above, the technical problem to be solved by this utility model is to provide a novel structural wooden door.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a novel structural wooden door, including two sets of metal frames, four sets of modular wooden boards sandwiched between the two sets of metal frames, a cross plate integrally formed in each of the two sets of metal frames, a sealing component sandwiched between the two sets of cross plates, the sealing component including a cross adhesive layer, the four sets of modular wooden boards respectively located in the four grooves of the cross adhesive layer, the cross adhesive layer is elastic and used to seal the gap between the four sets of modular wooden boards. The two sets of metal frames are connected by threaded bolts. Each set of modular wooden panels has a round hole for the bolts to pass through. The diameter of the round hole is larger than the diameter of the bolt, so that the position of the modular wooden panels can be adjusted when they expand or contract.

[0006] A further preferred embodiment of this utility model is: the modular wooden board includes multiple sets of wooden strips arranged and in contact with each other, with round holes opened on the outside of the wooden strips and extending through them; Both sets of metal frames have horizontally arranged plates, with fastening bolts passing through the plates on both sides, and an inner nut that is threadedly connected to the fastening bolt is provided on the outer side of one side of the plate.

[0007] A further preferred embodiment of this utility model is: a sleeve with multiple rings corresponding to the number and position of the round holes is fixed on the outer side of one side of the horizontal plate, the sleeve has a polygonal structure inside, and an inner nut is embedded in the sleeve.

[0008] A further preferred embodiment of this utility model is: each of the four grooves of the cross-shaped adhesive layer has multiple sets of continuous frame-shaped adhesive layers integrally formed. Sealing grooves are provided on all four sides of the wooden strip. The four sealing grooves form a continuous frame shape. The wooden strip is embedded into the corresponding frame-shaped adhesive layer, and the frame-shaped adhesive layer is embedded into the sealing groove and pressed against the inner wall of the sealing groove.

[0009] A further preferred embodiment of this utility model is: groove 1 and groove 2 are respectively opened on the two wooden strips closest to the side of the modular wooden board. Groove 1 is located on the transverse surface of the four sets of modular wooden boards, and groove 2 is located on the longitudinal surface of the four sets of modular wooden boards. Each of the four extension ends of the cross plate in both sets of metal frames has a snap plate. The four snap plates are snapped into the corresponding slots one and two respectively. The gap between the corresponding snap plates in the two sets of metal frames is the same as the thickness of the frame adhesive layer. The snap plates are located on the extension line of the cross adhesive layer and are used to limit the cross adhesive layer and the frame adhesive layer.

[0010] A further preferred embodiment of this utility model is that the width of the cross-shaped adhesive layer is the same as the thickness of the module wood board.

[0011] A further preferred embodiment of this utility model is that the width of the sealing groove is the same as the thickness of the frame-shaped adhesive layer, and the frame-shaped adhesive layer is adhered to the sealing groove.

[0012] A further preferred embodiment of this utility model is that both the cross-shaped adhesive layer and the frame-shaped adhesive layer are made of rubber and are used to seal the modular wooden board.

[0013] Compared with the prior art, the advantages of this utility model are: 1. The cross-shaped and frame-shaped adhesive layers have an elastic sealing function. When the modular wood panels expand or contract due to humidity changes, the rubber sealing layer can elastically deform accordingly, always tightly filling the gaps between the wood panels and maintaining airtightness.

[0014] 2. Through the cooperation of large-diameter round holes and fastening bolts, when the modular wood board expands due to moisture, it will move to a certain extent. Adjusting the position of the wooden strips can keep the overall frame of the wooden door relatively unchanged, increasing the pressure of the cross-hatching layer of the modular wood board. Conversely, when the modular wood board dries and shrinks, the pressure of the cross-hatching layer of the modular wood board is reduced. The overall outer frame size and shape of the door remain basically unchanged, so it can always perfectly match the door frame and will not have problems such as the door not closing or too large gaps.

[0015] 3. The frame-shaped adhesive layer is embedded in the sealing groove and is not directly exposed to the outside, which reduces the contact between the adhesive layer and ultraviolet rays and slows down the aging and hardening speed of the rubber material. Attached Figure Description

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0021] This embodiment mainly describes a novel structural wooden door. Please refer to [link / reference]. Figures 1-7Specifically, the following is proposed: Wooden doors made of heavy solid wood or solid wood composite structure can effectively slow down the heat conduction speed and reduce the loss of indoor heat to a certain extent, playing a basic role in heat preservation and energy saving. However, wooden doors will expand and contract to a certain extent under changes in humidity, and the gap between the wooden door and the door frame will change. Based on this, a new type of wooden door structure is proposed, including two sets of metal frames 1, with four sets of modular wooden boards 2 sandwiched between the two sets of metal frames 1. Each of the two sets of metal frames 1 has a cross plate 12, and a sealing component 3 is sandwiched between the two sets of cross plates 12. The sealing component 3 includes a cross glue layer 31, and the four sets of modular wooden boards 2 are respectively located in the four grooves of the cross glue layer 31. The cross glue layer 31 is elastic and is used to seal the gap between the four sets of modular wooden boards 2. Two sets of metal frames 1 are connected by threaded fastening bolts 4. Each set of modular wooden boards 2 has a round hole 22 for the fastening bolts 4 to pass through. The diameter of the round hole 22 is larger than the diameter of the fastening bolts 4, so that the position of the modular wooden boards 2 can be adjusted when they expand or contract.

[0022] Specifically, the two sets of metal frames 1 primarily function to limit the position of the four sets of modular wooden boards 2 and allow for adjustment. A cross-shaped adhesive layer 31 is sandwiched between the four sets of modular wooden boards 2. This adhesive layer 31 seals the gaps between the four sets of modular wooden boards 2 and possesses a certain degree of elasticity, allowing it to remain pressed against the four sets of modular wooden boards 2 even when their positions change, ensuring a sealed state. It should be noted that the cross-shaped adhesive layer 31 is pressed against the cross plates 12 of the two sets of metal frames 1 on both sides, further ensuring a seal. The modular wooden boards 2 are fixed by fastening bolts 4, which pass through circular holes 22 in the modular wooden boards 2. The diameter of the circular holes 22 is larger than the diameter of the fastening bolts 4. Loosening the fastening bolts 4 allows the limited modular wooden boards 2 to be adjusted to different positions.

[0023] like Figure 6 As shown, the modular wooden board 2 includes multiple sets of wooden strips 21 arranged and in contact with each other, and round holes 22 are opened on the outside of the wooden strips 21 and are provided through them; Both sets of metal frames 1 have horizontally arranged horizontal plates 11, and fastening bolts 4 pass through the horizontal plates 11 on both sides. An inner nut 42 that is threadedly connected to the fastening bolt 4 is provided on the outer side of one side of the horizontal plate 11.

[0024] Specifically, since the modular wooden board 2 has a relatively large area, it cannot be formed in one piece. Therefore, multiple sets of wooden strips 21 are spliced ​​together to form the required modular wooden board 2. It should be noted that each wooden strip 21 exists independently. The wooden strip 21 can be adjusted individually through the round holes 22 opened on it. It should also be noted that the wooden strip 21 can be adjusted by loosening the fastening bolts 4, and the position of the wooden strip 21 is fixed after the fastening bolts 4 are tightened.

[0025] like Figures 3-4 As shown, a number of sleeves 41 corresponding to the number and position of the round holes 22 are fixed on the outer side of one side of the horizontal plate 11. The sleeve 41 has a polygonal structure inside, and the inner nut 42 is embedded in the sleeve 41.

[0026] Specifically, the inner nut 42 is embedded in the sleeve 41, which keeps the inner nut 42 in a fixed state. The wooden strip 21 can be loosened or tightened simply by rotating the fastening bolt 4.

[0027] like Figure 6 As shown, each of the four grooves of the cross-shaped adhesive layer 31 contains multiple sets of continuous frame-shaped adhesive layers 32. Sealing grooves 25 are provided on all four sides of the wooden strip 21. The four sealing grooves 25 form a continuous frame shape. The wooden strip 21 is embedded into the corresponding frame-shaped adhesive layer 32, and the frame-shaped adhesive layer 32 is embedded into the sealing groove 25 and pressed against the inner wall of the sealing groove 25.

[0028] Specifically, the four right angles of the cross-shaped adhesive layer 31 are four grooves, and the grooves contain continuous frame-shaped adhesive layers 32. The sealing grooves 25 on the outer surface of the wooden strips 21 cooperate with the corresponding frame-shaped adhesive layers 32. Each wooden strip 21 is embedded in the frame-shaped adhesive layer 32. The wooden strips 21 are separated from each other by the frame-shaped adhesive layers 32. At the same time, the wooden strips 21 are in contact with each other. The frame-shaped adhesive layer 32 achieves a sealing function while preventing local exposure, maintaining elasticity, and extending its service life.

[0029] like Figure 5 As shown, the two wooden strips 21 closest to the side of the modular wooden board 2 are respectively provided with groove 1 23 and groove 24. Groove 1 23 is located on the transverse surface of the four sets of modular wooden boards 2, and groove 24 is located on the longitudinal surface of the four sets of modular wooden boards 2. In both sets of metal frames 1, the four extension ends of the cross plate 12 in each of the four directions are integrally equipped with a buckle plate 13. The four sets of buckle plates 13 are respectively fastened to the corresponding slot 1 23 and slot 2 24. The gap between the corresponding buckle plates 13 in the two sets of metal frames 1 is the same as the thickness of the frame-type adhesive layer 32. The buckle plate 13 is located on the extension line of the cross adhesive layer 31 and is used to limit the cross adhesive layer 31 and the frame-type adhesive layer 32.

[0030] Specifically, such as Figure 5 As shown, groove 1 23 is located at the top and bottom ends of the overall wooden door, and groove 2 24 is located on both sides. The horizontal and vertical snap plates 13 in the two sets of metal frames 1 are respectively snapped into groove 2 24 and groove 1 23 to limit the wooden strips 21 at the corresponding positions. At the same time, the gap between the symmetrical snap plates 13 in the two sets of metal frames 1 is the same as the width of the frame-type adhesive layer 32. Therefore, the frame-type adhesive layer 32 at the outer end of the cross adhesive layer 31 is limited to avoid positional deviation of the frame-type adhesive layer 32 at the outer end of the cross adhesive layer 31, which would affect the seal.

[0031] like Figure 6 As shown, the width of the cross-shaped adhesive layer 31 is the same as the thickness of the modular wooden board 2. Specifically, when the metal frames 1 on both sides are pressed against the modular wooden board 2, they are also pressed against the cross-shaped adhesive layer 31, further achieving a sealing state.

[0032] like Figure 6 As shown, the width of the sealing groove 25 is the same as the thickness of the frame-shaped adhesive layer 32, and the frame-shaped adhesive layer 32 is attached to the sealing groove 25, which increases the contact and compression area between the frame-shaped adhesive layer 32 and the sealing groove 25, thereby improving the sealing degree.

[0033] Both the cross-shaped adhesive layer 31 and the frame-shaped adhesive layer 32 are made of rubber and are used to seal the modular wooden board 2. Specifically, the rubber material is EPDM rubber, which is currently the most mainstream and best-performing choice for door and window sealing strips, especially suitable for cold northern regions. It should be noted that other rubber materials can also be used. Neither the cross-shaped adhesive layer 31 nor the frame-shaped adhesive layer 32 is fixed, so when disassembling the wooden door, the cross-shaped adhesive layer 31 and the frame-shaped adhesive layer 32 can be removed and replaced for easy operation.

[0034] Working principle: The cross-shaped adhesive layer 31 between the four sets of modular wooden boards 2 can adjust the position of the modular wooden boards 2 and change the degree of compression with the cross-shaped adhesive layer 31 when the wooden door expands due to changes in humidity. Since the cross-shaped adhesive layer 31 is made of rubber, it can produce a certain degree of deformation, thus maintaining compression with the modular wooden boards 2. Based on this, the position of the modular wooden boards 2 can be changed, but the overall frame remains unchanged, allowing for a perfect fit with the door frame. When the wooden door shrinks due to changes in humidity, the position of the cross-shaped adhesive layer 31 is changed as described above, keeping the modular wooden boards 2 and the cross-shaped adhesive layer 31 under compression, thus maintaining the overall frame of the modular wooden boards 2 and allowing for a perfect fit with the door frame.

[0035] It should be noted that, due to the relatively large area of ​​the wooden door, it cannot be made from a single piece of wood. Instead, multiple pieces of wood need to be spliced ​​together to form the required size of the wooden door. Based on this, the modular wooden board 2 is made up of multiple wooden strips 21 spliced ​​together. There are still gaps between the wooden strips 21 and the adjacent wooden strips 21. Under changes in humidity, air can easily flow, causing indoor heat to be quickly conducted to the outside through the door gaps. The frame-shaped adhesive layer 32 is used to seal the gaps between the wooden strips 21 and the adjacent wooden strips 21, so that the wooden strips 21 can be sealed even if they expand or contract. It should be noted that, since the outer side of the wooden strip 21 has a sealing groove 25 and the frame-shaped adhesive layer 32 is embedded in the sealing groove 25, the contact area between the frame-shaped adhesive layer 32 and the wooden strip 21 is relatively large, resulting in a better sealing effect. It should also be noted that the wooden strip 21 is in contact with the adjacent wooden strip 21, that is, the frame-shaped adhesive layer 32 located between the two is not exposed on the outside and is under compression, which can reduce its aging rate and extend its service life.

[0036] When adjusting the movement of the modular wooden board 2, the pressure of the two metal frames 1 and the cross plate 11 on the modular wooden board 2 is changed by loosening the fastening bolts 4, so that the wooden board strip 21 can move. Specifically, since the diameter of the round hole 22 is larger than that of the fastening bolt 4, the wooden board strip 21 can move. By striking the modular wooden board 2 with external force, the modular wooden board 2 can be moved to a certain extent. It should also be noted that the gap between the round hole 22 and the fastening bolt 4 is the range within which the wooden board strip 21 can move, which facilitates multi-directional adjustment.
