Description

Technical Field

[0001] This invention belongs to the field of wood veneer technology, and in particular relates to an assembled curved wood veneer and its installation method. Background Technology

[0002] Prefabricated decoration, as the name suggests, involves manufacturing all the necessary components in a factory and then transporting them to the construction site for assembly and installation. This eliminates the need for traditional on-site measurement and cutting of components, making construction simpler and more convenient. It can greatly improve the efficiency of on-site construction, and the construction site is cleaner and more aesthetically pleasing, generating less waste from decorative materials. It is a more environmentally friendly form of decoration construction.

[0003] Wood veneer is a common interior wall decoration structure. Current wood veneer installation methods require manual support or external support mechanisms to fix the veneer in place. Structural adhesive or screws are then used to secure the veneer to the wall or frame. Manual support results in poor stability, leading to insufficient tightness between veneers during installation. Using external support mechanisms requires repeated adjustments and replacements when installing veneers in different locations, making the process cumbersome and impacting construction progress. Furthermore, the use of numerous bolts or structural adhesives for fixing the veneer further complicates the process and hinders installation.

[0004] To address this issue, we designed a prefabricated curved wood veneer and its installation method. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a prefabricated arc-shaped wood veneer, comprising a wall and a first arc-shaped wood veneer. Two first arc-shaped wood veneers are fixed to the wall, and a plurality of second arc-shaped wood veneers are disposed between the two first arc-shaped wood veneers. Each of the two first arc-shaped wood veneers has a guide groove through its side facing each other. Guide plates are fixed on both sides of the second arc-shaped wood veneers and cooperate with the guide grooves. Two slots are opened opposite each other on the upper surface of the second arc-shaped wood veneers. Two inserts are fixed opposite each other on the lower surface of the upper side of the second arc-shaped wood veneers and cooperate with the slots. A fixing plate is fixed on the inner surface of the first arc-shaped wood veneers. A connecting plate is disposed on the inner side of the second arc-shaped wood veneers. The connecting plate has two notches opposite each other on its side facing the wall, which cooperate with the fixing plates on the left and right sides respectively.

[0007] A sleeve is fixed to the front surface of the connecting plate, and a fixing rod is fixed inside the sleeve. A first positioning mechanism and a second positioning mechanism are slidably mounted on the fixing rod, and a spring is connected between the first positioning mechanism and the second positioning mechanism. The first positioning mechanism cooperates with the connecting plate, and the second positioning mechanism cooperates with the second arc-shaped wood veneer.

[0008] The connecting plate is provided with two locking bolts, and the fixing plate is provided with several threaded holes. The inner end of the locking bolt passes through the threaded hole on the surface of the fixing plate and extends into the interior of the wall.

[0009] The first positioning mechanism includes a movable plate, a connecting arm, a positioning block, and a movable block. The connecting plate has two through slots on its surface. The two movable plates are respectively movably engaged with the through slots on the left and right sides. A support arm is fixedly connected between the upper end of the movable plate and the inner surface of the second arc-shaped wood veneer. The movable block is movably sleeved on the fixed rod. The sleeve has movable slots on both the left and right surfaces, which are connected to the inner cavity of the sleeve. The two connecting arms are fixedly fixed to the left and right surfaces of the movable block. The end of the connecting arm away from the movable block is fixedly connected to the positioning block.

[0010] The front surface of the connecting plate has two through holes that are connected to the through groove, and the through holes are movable to the positioning block. The lower side of the front surface of the movable plate has a first positioning hole, and the positioning block is in cooperation with the first positioning hole. The lower front side of the movable plate and the upper rear side of the positioning block are both arc-shaped structures.

[0011] The second positioning mechanism includes a positioning rod, which is slidably sleeved on the outside of the fixed rod. The front and rear ends of the spring are respectively connected to the positioning rod and the movable block. A second positioning hole is opened on the inner surface of the second arc-shaped wood veneer. The front end of the positioning rod passes through the sleeve and cooperates with the second positioning hole. The positioning rod and the sleeve are slidably cooperated. An arc-shaped groove is opened on the outer side of the second positioning hole along the vertical direction. The arc-shaped groove penetrates the lower surface of the second arc-shaped wood veneer. The front end of the positioning rod cooperates with the arc-shaped groove.

[0012] Mounting plates are fixed to both the upper and lower sides of the connecting plate, and fixing bolts are provided between the mounting plates and the wall.

[0013] A method for installing prefabricated curved wood veneer includes the following steps:

[0014] Step 1: First, adjust the notch on the connecting plate to press against the fixing plates on both sides, and make the connecting plate press against the bottom of the fixing plate. At the same time, adjust the locking bolt to screw it backward into the fixing plate to initially fix the connecting plate and the bottom of the fixing plate together.

[0015] Step 2: Select a suitable position on the wall and continue to adjust the locking bolts to turn them backward until they are screwed into the wall. Then, fix the first arc-shaped wood veneer on both sides to the suitable position on the wall. At the same time, use the fixing bolts to further fix the connecting plate to the wall.

[0016] Step 3: Adjust the guide plates on both sides of the second arc-shaped wood veneer to align with the guide grooves on the first arc-shaped wood veneer on the left and right sides respectively, and slide the second arc-shaped wood veneer downward to the bottom. During the downward sliding of the second arc-shaped wood veneer, the movable plate is driven to insert into the through groove. Combined with the arc-shaped structure of the lower front side of the movable plate and the upper rear side of the positioning block, the positioning block is pressed backward under the elastic action of the spring and inserted into the first positioning hole. At the same time, the positioning rod is pressed forward by the spring and slides into the second positioning hole along the arc-shaped groove to limit and fix the second arc-shaped wood veneer.

[0017] Step 4: Repeat the above operation. First, fix the connecting plate in a suitable position, and adjust the upper side of the second arc-shaped wood veneer to slide downwards to limit and fix the second arc-shaped wood veneer. At the same time, it will drive the insert plate to insert into the slot on the lower adjacent second arc-shaped wood veneer.

[0018] The present invention has the following beneficial effects:

[0019] This invention, through the cooperation of the notch and the fixing plate, facilitates the clamping of the connecting plate onto the two adjacent fixing plates on the left and right sides, thereby ensuring that the distance between the first arc-shaped wood veneer on the left and right sides is always fixed, which facilitates the installation of the second arc-shaped wood veneer. In particular, with the cooperation of the guide plate and the guide groove, it is easy to adjust the second arc-shaped wood veneer to slide downward in the vertical direction, driving the insert plate to insert into the slot on the lower side, which facilitates the insertion and fixing of the two adjacent second arc-shaped wood veneers. There is no need to use manual support or external support mechanism to support the arc-shaped wood veneer, which facilitates the installation of the arc-shaped wood veneer. It solves the drawback of manual support of wood veneer, which is poor stability and is prone to insufficient bonding between wood veneers. At the same time, it solves the drawback of using external support mechanism to support the arc-shaped wood veneer, which requires repeated adjustment and replacement of the position of the support mechanism when installing wood veneer in different positions, which is more cumbersome. It ensures the installation efficiency of the arc-shaped wood veneer.

[0020] During the downward sliding of the second curved wood veneer, the movable plate is inserted into the through groove. Under the elastic action of the spring, the movable block is pushed backward. Combined with the connecting arm, the positioning block is inserted into the first positioning hole. At the same time, the positioning rod is pushed forward by the spring and inserted into the second positioning hole, thus realizing the insertion and fixing of the second curved wood veneer, which facilitates the installation and fixing of the curved wood veneer.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] In the description of this invention, it should be understood that the terms "upper," "middle," "outer," "inner," etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0034] Please see Figures 1-7 As shown, a prefabricated arc-shaped wood veneer includes a wall 1 and a first arc-shaped wood veneer 2. Two first arc-shaped wood veneers 2 are fixed to the wall 1. Several second arc-shaped wood veneers 3 are arranged between the two first arc-shaped wood veneers 2. The sides of the two first arc-shaped wood veneers 2 that are close to each other are provided with guide grooves 4. Guide plates 5 are fixed on both sides of the second arc-shaped wood veneers 3 and cooperate with the guide grooves 4. Two slots 6 are opened opposite each other on the upper surface of the second arc-shaped wood veneers 3. Two inserts 7 are fixed opposite each other on the lower surface of the upper side of the second arc-shaped wood veneers 3 and cooperate with the slots 6. A fixing plate 8 is fixed on the inner surface of the first arc-shaped wood veneers 2. A connecting plate 9 is provided on the inner side of the second arc-shaped wood veneers 3. Two notches 10 are opened opposite each other on the side of the connecting plate 9 that are close to the wall 1 and cooperate with the fixing plates 8 on the left and right sides respectively.

[0035] With the cooperation of notch 10 and fixing plate 8, connecting plate 9 can be easily clamped onto two adjacent fixing plates 8 on the left and right sides, thus ensuring that the distance between the first arc-shaped wood veneer 2 on the left and right sides is always fixed, which facilitates the installation of the second arc-shaped wood veneer 3. With the cooperation of guide plate 5 and guide groove 4, it is easy to adjust the second arc-shaped wood veneer 3 to slide downward in the vertical direction, driving the insert plate 7 to be inserted into the slot 6 on the lower side, which facilitates the insertion and fixing of two adjacent second arc-shaped wood veneer 3. There is no need to use manual support or external support mechanism to support the arc-shaped wood veneer, which facilitates the installation of the arc-shaped wood veneer. It solves the problem that the manual support of wood veneer is not stable and is prone to insufficient bonding between wood veneers. At the same time, it solves the problem that when using external support mechanism to support the arc-shaped wood veneer, it is necessary to repeatedly adjust and change the position of the support mechanism when installing wood veneer in different positions, which is more cumbersome. It ensures the installation efficiency of the arc-shaped wood veneer.

[0036] A sleeve 12 is fixed on the front surface of the connecting plate 9. A fixing rod 13 is fixed inside the sleeve 12.

Two through slots 150 penetrate the surface of the connecting plate 9. The two movable plates 151 are respectively movably engaged with the through slots 150 on the left and right sides. A support arm is fixedly connected between the upper end of the movable plate 151 and the inner surface of the second arc-shaped wood veneer 3. The movable block 155 is movably sleeved on the fixed rod 13. Movable slots are provided on both the left and right surfaces of the sleeve 12, and these slots communicate with the inner cavity of the sleeve 12. A connecting arm 152 is fixed to the left and right surfaces of the movable block 155. The end of the connecting arm 152 away from the movable block 155 is fixedly connected to the positioning block 153. Two through holes are opened on the front surface of the connecting plate 9, which are connected to the through groove 150 and are movably engaged with the positioning block 153. A first positioning hole 154 is opened on the lower side of the front surface of the movable plate 151. The positioning block 153 and the first positioning hole 154 are engaged with each other. The lower front side of the movable plate 151 and the upper rear side of the positioning block 153 are both arc-shaped structures.

[0039] The second positioning mechanism 16 includes a positioning rod 160, which is slidably sleeved on the outside of the fixed rod 13. The front and rear ends of the spring 14 are respectively connected to the positioning rod 160 and the movable block 155. A second positioning hole 161 is opened on the inner surface of the second arc-shaped wood veneer 3. The front end of the positioning rod 160 passes through the sleeve 12 and cooperates with the second positioning hole 161. The positioning rod 160 and the sleeve 12 are slidably cooperated. An arc-shaped groove is opened on the outer side of the second positioning hole 161 along the vertical direction. The arc-shaped groove penetrates the lower surface of the second arc-shaped wood veneer 3. The front end of the positioning rod 160 cooperates with the arc-shaped groove.

[0040] Mounting plates are fixed on both the upper and lower sides of the connecting plate 9, and fixing bolts 17 are installed between the mounting plates and the wall 1.

[0041] A method for installing prefabricated curved wood veneer includes the following steps:

[0042] Step 1: First, adjust the notch 10 on the connecting plate 9 to press against the fixing plates 8 on the left and right sides, and make the connecting plate 9 press against the bottom of the fixing plate 8. At the same time, adjust the locking bolt 11 to screw it into the fixing plate 8 backward, so that the connecting plate 9 and the bottom of the fixing plate 8 are initially fixed together.

[0043] Step 2: Select a suitable position on wall 1, continue to adjust the locking bolt 11 and turn it backward until it is screwed into the interior of wall 1, thereby fixing the first arc-shaped wood veneer 2 on the left and right sides to the suitable position on wall 1, and at the same time, use the fixing bolt 17 to further fix the connecting plate 9 to wall 1.

[0044] Step 3: Adjust the guide plates 5 on both sides of the second arc-shaped wood veneer 3 to align with the guide grooves 4 on the first arc-shaped wood veneer 2 on the left and right sides respectively, and slide the second arc-shaped wood veneer 3 downward to the bottom. During the downward sliding of the second arc-shaped wood veneer 3, the movable plate 151 is driven to insert into the through groove 150. Combined with the arc-shaped structure of the lower front side of the movable plate 151 and the upper rear side of the positioning block 153, under the elastic action of the spring 14, the positioning block 153 is pressed backward and inserted into the first positioning hole 154. At the same time, the positioning rod 160 is pressed forward by the spring 14 and slides into the second positioning hole 161 along the arc-shaped groove to limit and fix the second arc-shaped wood veneer 3.

[0045] Step 4: Repeat the above operation. First, fix the connecting plate 9 in a suitable position, and adjust the upper side of the second arc-shaped wood veneer 3 to slide downward to limit and fix the second arc-shaped wood veneer 3. At the same time, it drives the insert plate 7 to insert into the slot 6 on the lower adjacent second arc-shaped wood veneer 3.

[0046] Example:

[0047] When installing the arc-shaped wood veneer, first adjust the notch 10 on the connecting plate 9 to press it onto the fixing plates 8 on the left and right sides, and make the connecting plate 9 press down on the bottom side of the fixing plate 8. At the same time, adjust the locking bolt 11 to screw it into the threaded hole at the bottom side of the fixing plate 8, so that the connecting plate 9 and the bottom side of the fixing plate 8 are initially fixed together, and then the two first arc-shaped wood veneers 2 are initially fixed on both sides of the connecting plate 9.

[0048] Then select a suitable position on the wall 1, adjust the locking bolt 11 to rotate backward, pass through the threaded hole on the fixing plate 8, and screw it into the wall 1, thereby fixing the first arc-shaped wood veneer 2 on the left and right sides to the wall 1, and at the same time, fix the connecting plate 9 to the wall 1 further by fixing bolt 17.

[0049] Next, adjust the guide plates 5 on both sides of the second arc-shaped wood veneer 3 to align with the guide grooves 4 on the left and right sides of the first arc-shaped wood veneer 2, and slide the second arc-shaped wood veneer 3 down to the bottom;

[0050] During this process, under the combined action of the arc-shaped structure of the lower front side of the movable plate 151 and the upper rear side of the positioning block 153, the second arc-shaped wood veneer 3 drives the movable plate 151 to insert into the through groove 150 and presses the positioning block 153 forward until the second arc-shaped wood veneer 3 slides to the lowest side. Under the elastic action of the spring 14, the positioning block 153 is pressed backward and inserted into the first positioning hole 154.

[0051] Under the action of the arc groove on the inner side of the second arc wood veneer 3, combined with the spring 14, the positioning rod 160 is pressed forward and slides into the second positioning hole 161 along the arc groove to insert and fix the second arc wood veneer 3.

[0052] Following the same principle, the upper connecting plate 9 is fixed in a suitable position, and the upper second arc-shaped wood veneer 3 is adjusted to slide downward. While the second arc-shaped wood veneer 3 is inserted and fixed, the insert plate 7 is driven to insert into the slot 6 on the lower adjacent second arc-shaped wood veneer 3, realizing the splicing and fixing of the two adjacent second arc-shaped wood veneers 3, effectively improving the installation efficiency of the arc-shaped wood veneer.

[0053] It should be further noted that the installation method, connection method and setting method in this invention are all common mechanical connection methods in the field and well known and mastered by those skilled in the art. Any method that can achieve its beneficial effects can be implemented.
