Description

Technical Field

[0001] This utility model belongs to the field of solid wood flooring technology, specifically relating to a new three-layer solid wood flooring structure. Background Technology

[0002] Solid wood flooring is a floor covering material made from natural wood that has been dried and processed. Also known as hardwood flooring, it is made directly from solid wood. It retains the natural grain of the wood, is a poor conductor of heat, providing warmth in winter and coolness in summer, and is comfortable underfoot and safe to use, making it an ideal material for bedrooms, living rooms, studies, and other flooring applications.

[0003] A domestic utility model patent with application number CN202220774391.2 discloses a new three-layer flooring, belonging to the field of wood flooring technology. This new three-layer flooring includes a wooden base layer, a positioning mechanism, and a locking mechanism. A wooden surface layer is provided on the upper surface of the wooden base layer, and a wooden bottom layer is provided on the lower surface of the wooden base layer. Locking plates are provided on the left and right sides of the lower surface of the wooden surface layer and on the left and right sides of the upper surface of the wooden bottom layer. Locking grooves are provided on the left and right sides of the upper surface and the left and right sides of the lower surface of the wooden base layer, and locking mechanisms are provided in all four locking grooves. This utility model effectively solves the problems of poor breathability in existing multi-layer composite flooring, resulting in slow heat conduction to the floor surface. Furthermore, it addresses the issues of poor stability, susceptibility to deformation, and low thermal conductivity in harsh environments such as geothermal heating, leading to a low safety factor for the flooring. Additionally, in harsh environments, the adhesive between the multiple layers of composite flooring can separate, causing the wood flooring to warp. Solid wood flooring, besides improper installation, can also warp when affected by temperature and humidity. When flooring absorbs water, it expands laterally, or insufficient expansion joints can cause the flooring to swell and become compressed. In winter, heating radiators or underfloor heating systems retain heat in the flooring area, causing the wood to dehydrate and shrink locally, leading to warping and buckling at the edges. To reduce warping, it's essential to ensure the flooring's breathability and thermal conductivity. The aforementioned utility model uses a locking mechanism to enhance the connection between the three layers of wood panels. However, the locking mechanism's components include metal parts. Over time, this can cause deformation of the heat-storing metal within the locking mechanism's cavity, or corrosion due to moisture, making replacement difficult and significantly impacting the connection between the wood panels. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a new three-layer solid wood flooring structure. The solid wood flooring includes a wooden base layer, a wooden surface layer attached to the top of the wooden base layer by adhesive, and a wooden bottom layer attached to the bottom of the wooden base layer by adhesive. The wooden base layer has a snap-fit ​​part and a positioning part at both ends. A fixing block is provided at the middle position of the snap-fit ​​part, and a limiting block is provided at the middle position of the positioning part. The limiting block and the fixing block are installed together, and the positioning part and the snap-fit ​​part are installed together. The snap-fit ​​part includes two sets of snap-fit ​​top plates and snap-fit ​​bottom plates located at the top and bottom of the fixing block, respectively. Multiple sets of ventilation holes are opened through the fixing block on the snap-fit ​​top plate and the snap-fit ​​bottom plate.

[0005] As a further preferred technical solution of this utility model, an auxiliary top groove and an auxiliary bottom groove are respectively provided between the snap-fit ​​top plate, the snap-fit ​​bottom plate and the fixing block, and a butt joint arc groove is provided near the wooden base layer of both the snap-fit ​​top plate and the snap-fit ​​bottom plate, and a snap-fit ​​inclined surface is provided at the top of the snap-fit ​​top plate and the bottom of the snap-fit ​​bottom plate.

[0006] The installation is made more secure between the wooden base layers by clamping the bevel.

[0007] As a further preferred technical solution of this utility model; the positioning part includes a top positioning block and a bottom positioning block respectively disposed on the top and bottom of the limiting block. The ends of the top positioning block and the bottom positioning block are provided with positioning arc surfaces. The top positioning block is installed with the top of the snap-fit ​​top plate and the bottom positioning block is installed with the bottom of the snap-fit ​​bottom plate. The positioning arc surfaces are all installed with the docking arc groove. After installation, there is a breathable gap between the positioning arc surface and the docking arc groove.

[0008] Positioning the curved surface and the mating groove during installation prevents the floorboards from warping or chipping at the joint due to being stepped on during use.

[0009] As a further preferred technical solution of this utility model; the limiting block is provided with a limiting groove that cooperates with the fixing block for limiting, and limiting strips are respectively installed at the top and bottom of the limiting groove. The limiting strips are respectively inserted into the auxiliary top groove and the auxiliary bottom groove for limiting. The top and bottom of the limiting block are provided with locking grooves, and the locking grooves are respectively locked and installed with the locking top plate and the locking bottom plate.

[0010] The snap-fit ​​top and bottom plates are secured to the snap-fit ​​groove by a snap-fit ​​bevel, ensuring the stability of the solid wood flooring during installation. Furthermore, the vents allow heat from the underfloor heating system installed underneath the solid wood flooring to be quickly dissipated into the room, ensuring excellent ventilation.

[0011] As a further preferred technical solution of this utility model, the two ends of the wood surface layer are respectively provided with a pressing part and a reserved part, and a reserved expansion joint is provided between the pressing part and the reserved part. The bottom end of the pressing part is limited and fixed to the end of the top positioning block.

[0012] There is a distance between the reserved part and the top of the top positioning block, and the bottom of the pressing part extends a distance beyond the snap-fit ​​part, so that the top of the top positioning block and the bottom of the pressing part make supporting contact.

[0013] As a further preferred technical solution of this utility model, the two ends of the wooden bottom layer are respectively provided with a close-fitting part and a connecting part, and a reserved installation gap is provided between the close-fitting part and the connecting part. The top end of the close-fitting part is limited and fixed to the bottom end of the bottom positioning block.

[0014] By pressing and positioning the top of the adjacent part with the bottom positioning block, the stability of the installation between solid wood flooring is ensured. Solid wood flooring has the characteristics of thermal expansion and contraction. In order to prevent the flooring from expanding and arching after being exposed to moisture or temperature changes, gaps must be reserved during installation. The setting of reserved installation gaps and reserved expansion gaps facilitates heat conduction. Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The top and bottom plates are secured to the locking grooves via a beveled locking mechanism, ensuring the stability of the solid wood flooring during installation. The vents allow heat from the underfloor heating system to escape upwards through the vents, along with pre-reserved installation and expansion joints, ensuring rapid heat transfer to the room and providing excellent ventilation. Furthermore, water droplets from mopping are blocked at the top of the flooring by a support block extending from the bottom of the clamping section to the bottom of the clamping section, slowing moisture absorption and allowing the water to dry naturally in the air, thus minimizing the impact of humidity on the flooring.

[0016] 2. The laminated flooring is made of three layers of wood veneer pressed vertically and interlaced. The grain direction of each layer cancels out the internal stress, greatly reducing the risk of warping and cracking caused by thermal expansion and contraction. The bottom positioning blocks press and position the top of the adjacent section, ensuring stable installation between the bottom layer and the core of the solid wood flooring.

[0019] This specific embodiment is a new three-layer solid wood flooring structure.

[0020] Besides improper installation, solid wood flooring can also warp due to temperature and humidity fluctuations. When the flooring absorbs water, it expands laterally, or insufficient expansion joints cause the flooring to swell. In winter, heating radiators or underfloor heating systems retain heat in the flooring area, causing the wood to dehydrate and shrink locally, leading to warping and buckling at the edges. To reduce warping, it's essential to ensure the flooring's breathability and thermal conductivity. The aforementioned utility model uses a locking mechanism to enhance the connection between the three layers of wood panels. However, the components of this mechanism include metal parts. Over time, this can cause deformation of the heat-storing metal within the locking mechanism cavity, or corrosion due to moisture, making replacement difficult and significantly impacting the connection between the wood panels.

[0021] Example 1: Its structural schematic diagram is as follows Figures 1-6 As shown. A new three-layer solid wood flooring structure, the solid wood flooring 1 includes a wooden base layer 3, a wooden surface layer 2 glued to the top of the wooden base layer 3, and a wooden bottom layer 4 glued to the bottom of the wooden base layer 3. The wooden base layer 3 has a snap-fit ​​part 31 and a positioning part 32 at both ends, a fixing block 34 at the middle position of the snap-fit ​​part 31, and a limiting block 33 at the middle position of the positioning part 32. The limiting block 33 and the fixing block 34 are connected and installed together, and the positioning part 32 and the snap-fit ​​part 31 are connected and installed together. The snap-fit ​​part 31 includes two sets of snap-fit ​​top plates 311 and snap-fit ​​bottom plates 312 located at the top and bottom of the fixing block 34, respectively. Multiple sets of ventilation holes 35 are opened through the fixing block 34 on the snap-fit ​​top plates 311 and the snap-fit ​​bottom plates 312.

[0022] Auxiliary top groove 341 and auxiliary bottom groove 342 are respectively provided between the snap-fit ​​top plate 311, snap-fit ​​bottom plate 312 and fixing block 34, and both the snap-fit ​​top plate 311 and snap-fit ​​bottom plate 312 are provided with butt joint arc grooves 314 near the wooden base layer 3. The top of the snap-fit ​​top plate 311 and the bottom of the snap-fit ​​bottom plate 312 are provided with clamping slopes 313. The clamping slopes 313 increase the tightness of the installation between the wooden base layers 3. The positioning part 32 includes a top positioning block 321 and a bottom positioning block 322 respectively disposed at the top and bottom of the limiting block 33. Both the top positioning block 321 and the bottom positioning block 322 have positioning arc surfaces 323 at their ends. The top positioning block 321 is installed at the top of the snap-fit ​​top plate 311, and the bottom positioning block 322 is installed at the bottom of the snap-fit ​​bottom plate 312. The positioning arc surfaces 323 are also installed in conjunction with the mating arc grooves 314. A ventilation gap 36 is provided between the installed positioning arc surfaces 323 and the mating arc grooves 314. The positioning arc surfaces 323 and the mating arc grooves 314 are positioned to prevent the floorboards from warping or chipping at the joint due to foot traffic during use. The limiting block 33 has a limiting groove 332 that cooperates with the fixing block 34 for limiting. Limiting strips 333 are installed at the top and bottom of the limiting groove 332, respectively. These limiting strips 333 are inserted into the auxiliary top groove 341 and auxiliary bottom groove 342 for limiting. The limiting block 33 also has locking grooves 331 at both the top and bottom, which are respectively engaged with the locking top plate 311 and locking bottom plate 312. The locking top plate 311 and locking bottom plate 312 are locked to the locking grooves 331 by locking bevels 313, ensuring the stability of the solid wood flooring 1 during installation. Furthermore, the vent 35 allows heat from the underfloor heating system installed at the bottom of the solid wood flooring 1 to be quickly dissipated upwards through the vent 35 at the vent gap 36, ensuring good ventilation.

[0023] The wood surface layer 2 has a pressing part 21 and a reserved part 22 at both ends, with a reserved expansion joint 23 between the pressing part 21 and the reserved part 22. The bottom end of the pressing part 21 is fixed to the end of the top positioning block 321. There is a distance between the reserved part 22 and the top of the top positioning block 321, and the bottom of the pressing part 21 extends a distance beyond the locking part 31, so that the top of the top positioning block 321 and the bottom of the pressing part 21 make support contact. When there are water droplets caused by mopping on the top of the solid wood floor 1, the water droplets are blocked at the position where the top of the top positioning block 321 and the bottom of the pressing part 21 make support contact from the bottom of the pressing part 21 to the locking part 31, which slows down the moisture from sinking into the interior of the solid wood floor 1. As the water droplets dry in the air, the impact of moisture on the solid wood floor is reduced. The wooden base layer 4 has a contact part 41 and a connecting part 42 at both ends, with a reserved installation gap 43 between the contact part 41 and the connecting part 42. The top end of the contact part 41 is fixed to the bottom end of the bottom positioning block 322. The bottom positioning block 322 presses and positions the top of the contact part 41, ensuring the stability of the installation between the solid wood flooring 1. Solid wood flooring 1 has the characteristic of thermal expansion and contraction. In order to prevent the flooring from expanding and arching after moisture or temperature changes, gaps must be reserved during installation. The reserved installation gap 43 and reserved expansion gap 23 facilitate heat conduction. The glued flooring is made of three layers of wood veneer pressed vertically and crosswise. The grain direction of each layer of wood cancels out the internal stress, greatly reducing the risk of arching and cracking caused by thermal expansion and contraction. The wooden base layer 3 is preferably made of teak. Teak itself contains natural oils, has high breathability, and has a certain moisture-proof effect.

[0024] First, the solid wood flooring 1 is secured to the top plate 311 and bottom plate 312 by the locking groove 331 and the locking bevel 313, ensuring the stability of the solid wood flooring 1 during installation. Furthermore, with the setting of the vent 35, when the solid wood flooring 1 is in use, the heat emitted by the underfloor heating system installed at its bottom can be discharged upward through the vent 35 at the vent gap 36, as well as the reserved installation gap 43 and reserved expansion gap 23, ensuring that the heat of the underfloor heating system is quickly discharged to the room, with good ventilation effect.

[0025] All technical features in this embodiment can be freely combined according to actual needs.

[0026] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
