[0019] A method for installing an assembled wood-plastic wall panel comprises the following steps:

[0020] ①Wall installation preparation: clean the wall, drill holes on the cleaned wall with an electric drill, and then lay the WPC keel on the cleaned wall, so that the length direction of the WPC keel is perpendicular to the horizontal plane, and use expansion screws to connect and fix the WPC keel to the wall;

[0021] ②Installation at the corner of the wall:

[0022] 2.1. When the corner of the wall is an outer corner: select one of the second matching strips of the auxiliary matching strips to be plugged into the matching groove of the wood-plastic board, so that the movable groove of the auxiliary matching strip faces the side away from the decorative surface of the wood-plastic board, and then plug the first matching strip of the main matching strip into the matching groove of the other wood-plastic board, and then lay the two wood-plastic boards on both sides of the outer corner of the wall respectively, so that the main matching strip and the auxiliary matching strip are against each other and close to the position close to the outer corner of the wall, and at the same time, the storage groove of the main matching strip is directly opposite to the movable groove of the auxiliary matching strip, and the flanges of the two wood-plastic boards are kept upward, and then the fork block is inserted into the working channel by using the extension rod, and the fork is inserted into the working channel. The fork of the mouth block is plugged into the outer periphery of the movable rod, and then the movable rod is moved toward the end of the hook matching groove along the L-shaped direction of the guide groove by using the extension rod. When the movable rod moves to the end position of the hook matching groove away from the displacement groove, the buckling mouth between the push strip and the buckling strip is buckled and connected with the limit rod, and the matching limit block is plugged into the communication position between the working groove of the main matching strip and the sink groove of the auxiliary matching strip to limit the movement of the movable block, and then the flange of the wood-plastic board is connected to the wood-plastic keel by screws, and the nut of the screw is flush with the surface of the flange, and then it is installed upward in sequence, and the strip groove of the wood-plastic board at the top is plugged and matched with the flange of the adjacent wood-plastic board below;

[0023] 2.2. When the corner of the wall is an inner corner: select one of the second matching strips of the secondary matching strips to be plugged into the matching groove of the wood-plastic board, so that the movable groove of the secondary matching strip faces the side close to the decorative surface of the wood-plastic board, and then plug the first matching strip of the main matching strip into the matching groove of the other wood-plastic board, and then lay the two wood-plastic boards on both sides of the outer corner of the wall respectively, so that the main matching strip and the secondary matching strip are against each other and close to the position close to the inner corner of the wall, and at the same time, the storage groove of the main matching strip is directly opposite to the movable groove of the secondary matching strip, and the flanges of the two wood-plastic boards are kept upward, and then the buckle mouth of the main matching strip of one of the wood-plastic boards at the same inner corner is buckled and connected with the limit strip of the secondary matching strip of the other wood-plastic board according to the above-mentioned installation method, and the wood-plastic boards are installed one by one from bottom to top;

[0024] ③ Wall main body installation: After the wood-plastic board at the corner of the wall is installed, the wood-plastic board is further installed from the wall near the corner of the wall in the direction away from the corner of the wall. During the installation process, the wood-plastic boards are laid one by one from bottom to top on the surface formed by several wood-plastic keels. In the process of laying the wood-plastic boards, the strip grooves of the upper wood-plastic boards are plugged with the flanges of the lower wood-plastic boards. After the strip grooves of each wood-plastic board are plugged with the flanges of the lower wood-plastic boards, they are all locked and connected with the corresponding wood-plastic keels on the flanges of the wood-plastic boards by screws, and the nuts of the screws are flush with the surface of the flanges. According to the above method, the wood-plastic boards are installed in the direction away from the corner of the wall, and the wood-plastic boards cover the original cavities to form new wood-plastic wall surfaces, thereby completing the installation operation of the wood-plastic boards.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] An assembled wood-plastic wall panel is intended to solve the problem in the prior art that the wood-plastic panels that use right-angle bars to connect adjacent wood-plastic wall surfaces are prone to debonding, resulting in unstable connections, or the nuts that are locked by screws are exposed, affecting the overall appearance. Therefore, the main matching strip and the auxiliary matching strip are detachably connected at the two opposite end faces of the wood-plastic panel, so that the two wood-plastic panels on both sides of the corner of the wall can be connected by the main matching strip and the auxiliary matching strip connected thereto, thereby replacing the structure of the right-angle strip in the prior art. Specifically, when installing the wood-plastic panel on the wall, when encountering the corner position of the wall, it can be determined whether the corner is an inner corner or an outer corner. At the same time, since the cross-section of the auxiliary matching strip is square, one of the connecting pieces in the auxiliary matching strip can be selected to be detachably connected to the side of the wood-plastic panel, thereby adjusting the orientation of the matching part of the auxiliary matching strip, thereby achieving the effect of adapting to the plane, the inner corner and the outer corner. At the same time, in the process of connecting the wood-plastic panels on both sides of the wall corner through the main matching strip and the auxiliary matching strip, the main matching strip of the wood-plastic panels at both ends and the auxiliary matching strip of the other wood-plastic panel are both moved closer to the same corner position until the main matching strip and the auxiliary matching strip are against each other. At the same time, the auxiliary matching strip is connected to its wood-plastic panel by selecting one of the connecting pieces, so that the matching part of the auxiliary matching strip is directly opposite to the notch of the storage groove of the main matching strip, and then it is convenient to adjust the position of the movable rod later, so that the fastening piece on the movable rod can be detachably connected to the matching part. Further, by setting a guide groove, the movable rod follows the guiding effect of the guide groove to drive the fastening piece to move toward the outside of the storage groove, and finally realizes the function of detachably connecting with the matching part of the auxiliary matching strip. At the same time, by setting a movable stopper between the end of the main matching strip along the length direction and the movable rod, the movable stopper is connected to the movable rod and the main matching strip at the same time, so as to limit the situation where the movable rod continues to move in the guide groove, so as to further improve the beneficial effect of the stability of the connection between the main matching strip and the auxiliary matching strip. Thus, the method of connecting the right-angle bars by fixing glue or screws in the prior art is replaced, and the beneficial effects of stable installation and beautified overall appearance are achieved.

[0027] A method for installing assembled wood-plastic wall panels mainly divides the method into three processes: wall installation preparation process, wall corner installation process, and wall main body installation process. In the wall corner installation process, there are two installation situations: inner corner and outer corner. Thus, the assembled wood-plastic wall panels of the present invention can be installed on the wall as a whole, and are also suitable for installation of different corner types, thereby replacing the operation of using right-angle bars for corner auxiliary installation in the prior art, and can reduce the situation of fixing glue and screwing in corners, so as to stabilize the overall structure and beautify the overall appearance. At the same time, it should be further explained that, since the installation method of the present invention mainly starts with the wood-plastic board from the corner position, and then installs the wood-plastic board from the corner position to the middle position of the wall, when the wood-plastic board in the middle position is too long, the wood-plastic board can be cut in time and then assembled, thereby achieving the beneficial effect of reducing the scientific installation operation and making the overall wall neat.

DETAILED DESCRIPTION

[0043] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The terms such as "upper", "inner", "middle", "left", "right" and "one" cited in this specification are only for the convenience of description, and are not used to limit the scope of the present invention. The change or adjustment of their relative relationship shall also be regarded as the scope of the present invention without substantially changing the technical content.

[0044] Reference Figures 1 to 14As shown, an assembled wood-plastic surface wall panel comprises a wood-plastic board 1, wherein two opposite end surfaces of the wood-plastic board 1 are respectively provided with flanges 11 and strip grooves, wherein the strip grooves in this embodiment are not fully shown in the drawings of the specification, and the other two opposite end surfaces of the wood-plastic board 1 are respectively detachably connected with a main matching strip 2 and a secondary matching strip 4; the cross section of the secondary matching strip 4 is square, and three side surfaces of the secondary matching strip 4 are provided with connectors detachably connected to the wood-plastic board 1, and the other side surface of the secondary matching strip 4 is provided with a matching portion; the side of the main matching strip 2 away from the wood-plastic board 1 is provided with a storage groove 21, and the end of the main matching strip 2 along the length direction ... A guide groove 22 runs through the surface, and the guide groove 22 is connected to the receiving groove 21. A movable rod 3 is inserted into the receiving groove 21. The movable rod 3 runs through the guide groove 22 and the receiving groove 21. The movable rod 3 is connected with a fastening piece, and the receiving groove 21 is for receiving the fastening piece. The movable rod 3 moves toward the outside of the receiving groove 21 through the guide groove 22 and is detachably connected with the matching part of the adjacent auxiliary matching strip 4; when the fastening piece of the movable rod 3 is detachably connected with the matching part of the auxiliary matching strip 4, a movable limiting piece is arranged between the end face of the main matching strip 2 along the length direction and the movable rod 3.

[0045] The present invention aims to solve the problem that the wood-plastic board 1 connected to adjacent wood-plastic wall surfaces by right-angle bars in the prior art is prone to debonding and unstable connection, or the screw locking nut is exposed and affects the overall appearance. Therefore, the main matching strip 2 and the auxiliary matching strip 4 are detachably connected at the two opposite end faces of the wood-plastic board 1, so that the two wood-plastic boards 1 on both sides of the corner of the wall can be connected by the main matching strip 2 and the auxiliary matching strip 4 connected thereto, thereby replacing the structure of the right-angle bar in the prior art. Specifically, when the wood-plastic board 1 is installed on the wall, when encountering the corner position of the wall, it can be selected according to whether the corner is an inner corner or an outer corner. At the same time, since the cross section of the auxiliary matching strip 4 is square, one of the connecting parts in the auxiliary matching strip 4 can be detachably connected to the side of the wood-plastic board 1, thereby adjusting the direction of the matching part of the auxiliary matching strip 4, thereby achieving the effect of adapting to the plane, the inner corner and the outer corner. At the same time, in the process of connecting the wood-plastic panels 1 on both sides of the wall corner through the main matching strips 2 and the auxiliary matching strips 4, the main matching strips 2 of the wood-plastic panels 1 at both ends and the auxiliary matching strips 4 of the other wood-plastic panel 1 are both moved toward the same corner position until the main matching strips 2 and the auxiliary matching strips 4 are abutted against each other. At the same time, the auxiliary matching strips 4 are connected to their wood-plastic panels 1 by selecting one of the connecting pieces, so that the matching portion of the auxiliary matching strips 4 is directly opposite to the notch of the receiving groove 21 of the main matching strip 2, thereby facilitating the subsequent adjustment of the position of the movable rod 3, so that the fasteners on the movable rod 3 can be detachably connected to the matching portion.

[0046] Furthermore, by setting the guide groove 22, the movable rod 3 follows the guiding effect of the guide groove 22 to drive the fastener to move toward the outside of the storage groove 21, and finally realizes the function of detachable connection with the matching part of the auxiliary matching strip 4. At the same time, by setting a movable stopper between the end of the main matching strip 2 in the length direction and the movable rod 3, the movable stopper is connected to the movable rod 3 and the main matching strip 2 at the same time, thereby limiting the situation where the movable rod 3 continues to move in the guide groove 22, so as to further improve the beneficial effect of the stability of the connection between the main matching strip 2 and the auxiliary matching strip 4. In this way, the method of replacing the connection of the right-angle strip by fixing glue or screws in the prior art is realized, and the beneficial effects of stable installation and overall beautification of the appearance are achieved.

[0047] Reference Figures 1 to 14 As shown, in order to realize the function of the movable rod 3 being detachably connected to the matching part of the buckle piece and the auxiliary matching strip 4 by the guiding effect of the guide groove 22, the matching part includes a movable groove 41 which is opened on the side of the auxiliary matching strip 4 away from its three connecting parts, and the movable groove 41 extends along the length direction of the auxiliary matching strip 4. The inner wall of the movable groove 41 is fixedly connected to a limiting rod 44, and the two ends of the limiting rod 44 are respectively fixedly connected to the two inner walls of the movable groove 41 along the length direction of the auxiliary matching strip 4. The length direction of the limiting rod 44 is consistent with the length direction of the auxiliary matching strip 4, and there is a distance between the limiting rod 44 and the inner wall of the movable groove 41.

[0048] The fastening part includes a pushing bar 31 fixedly connected to the movable rod 3, the length direction of the pushing bar 31 is consistent with the length direction of the movable rod 3, the cross-section of the pushing bar 31 is L-shaped, and the L-shaped opening of the pushing bar 31 is arranged toward the storage groove 21, and the end of the pushing bar 31 away from the movable rod 3 is fixedly connected with a fastening bar 32, the cross-section of the fastening bar 32 is a bar shape, and a fastening opening 33 is formed between the length direction of the cross-section of the fastening bar 32 and the cross-section of the pushing bar 31 away from the end of the movable rod 3, and the fastening opening 33 between the pushing bar 31 and the fastening bar 32 faces the storage groove 21.

[0049] The guide groove 22 includes a displacement groove 221 and a hook groove 222 that are connected. The cross section of the displacement groove 221 is L-shaped. The L-shaped corner opening of the cross section of the displacement groove 221 is in the same direction as the L-shaped corner opening of the cross section of the push bar 31. The cross section of the hook groove 222 is in the shape of a strip. One end of the cross section of the hook groove 222 in the length direction is connected to the end of the cross section of the displacement groove 221 in the length direction and close to the notch of the receiving groove 21. The displacement groove 221 A corner opening is formed between the cross-sectional length direction and the end of the cross-sectional area of ​​the hook-matching groove 222 close to the slot opening of the receiving groove 21, and the corner opening is consistent in direction and size with the snap-fit ​​opening 33 between the pushing strip 31 and the snap-fit ​​strip 32, and the angle between one end of the cross-sectional length direction of the hook-matching groove 222 and the end of the cross-sectional length direction of the displacement slot 221 close to the slot opening of the receiving groove 21 is consistent with the angle between the snap-fit ​​strip 32 and the end of the pushing plate away from the movable rod 3, and the length of the cross-sectional area of ​​the hook-matching groove 222 is consistent with the length of the cross-sectional area of ​​the snap-fit ​​strip 32.

[0050] When the main matching strip 2 and the auxiliary matching strip 4 are abutted against each other and the storage groove 21 is directly opposite to the movable groove 41 in the initial state, along the connection direction of the main matching strip 2 and the auxiliary matching strip 4, the limiting rod 44 and the pushing plate are not in the same straight line, and along the connection direction perpendicular to the main matching strip 2 and the auxiliary matching strip 4, the limiting rod 44 is located on the side of the buckling strip 32 away from the pushing strip 31, and when the movable rod 3 is moved to the intersection between the displacement groove 221 and the hook groove 222, the buckling opening 33 between the pushing strip 31 and the buckling strip 32 is directly opposite to the limiting rod 44, so as to facilitate the subsequent reverse pull and buckling operation; and then when the moving rod is moved to the end of the hook groove 222 away from the displacement groove 221, the buckling strip 32 of the buckling part is buckled and pulled, so that the buckling opening 33 between the pushing strip 31 and the buckling strip 32 is buckled and connected with the limiting opening.

[0051] Specifically, since the overall cross-section of the fastening member is L-shaped, it is specifically composed of a push strip 31 with an L-shaped cross-section and a fastening strip 32 with a strip-shaped cross-section fixedly connected, and then by setting a guide groove 22 composed of a displacement groove 221 and a hook matching groove 222, the displacement sliding movable rod 3 with an L-shaped cross-section is When it reaches the end position close to the notch of the storage slot 21, that is, the intersection between the cross section of the displacement slot 221 and the hook groove 222, on the one hand, the problem of collision and interference between the push bar 31 and the buckling bar 32 and the limit rod 44 can be reduced during the movement. At the same time, at the intersection between the displacement slot 221 and the hook groove 222, the buckling opening 33 between the push bar 31 and the buckling bar 32 can be directly opposite to the limit rod 44, so as to facilitate the subsequent reverse pulling along the cross section of the hook groove 222 in the direction away from the notch of the storage slot 21, so as to make the buckling opening 33 and the limit rod 44 buckle and connect, so as to reduce the problem of collision and interference between the buckling bar 32 and the limit rod 44. Therefore, the movable rod 3 is finally slid in the cross section of the hook groove 222 along the direction away from the slot of the receiving slot 21 to the position at the end of the hook groove 222, so that the snap-fitting opening 33 is snap-fitted with the limiting rod 44, thereby achieving a detachable connection and making the main mating strip 2 and the auxiliary mating strip 4 installed stably.

[0052] Reference Figures 1 to 14 As shown, in order to further improve the stability of the buckling connection between the buckling opening 33 and the limiting bar and reduce the situation where the limiting bar is separated from the buckling opening 33 between the pushing bar 31 and the buckling bar 32. The angle between the length direction of the cross section of the buckling bar 32 and the L-shaped direction of the cross section of the pushing bar 31 away from the end of the movable rod 3 is an acute angle, and the curvature radius of the inner wall of the buckling opening 33 between the pushing bar 31 and the buckling bar 32 is consistent with the curvature radius of the outer peripheral surface of the pushing rod. Specifically, by limiting the angle between the length direction of the cross section of the locking strip 32 and the cross section of the pushing strip 31 away from the end of the movable light rod, the length direction of the cross section of the hook groove 222 and the end of the L-shaped cross section of the displacement groove 221 close to the slot opening of the storage slot 21 are equal to the above-mentioned angle, and the length of the cross section length direction of the hook groove 222 is consistent with the length of the cross section length direction of the locking strip 32. Therefore, when the movable rod is slid from the intersection between the hook groove 222 and the displacement groove 221 to the position where the hook groove 222 is away from the end of the displacement groove 221, the outer peripheral surface of the movable rod 3 can be well fitted with the inner wall of the locking opening 33, and the movable rod 3 can be limited within the acute angle of the locking opening 33 between the locking strip 32 and the pushing strip 31, which is beneficial to reduce the separation of the movable rod 3 and the locking opening 33, thereby further improving the locking connection stability of the locking opening 33 of the locking piece and the limiting rod 44.

[0053] In order to reduce the rotation of the fastening parts along the axis of the movable rod 3 during the movement of the movable rod 3 along the trajectory direction of the cross-section of the guide groove 22, thereby reducing the effectiveness of the fastening connection between the fastening strip 32 and the push strip 31 of the subsequent fastening parts and the fastening opening 33 and the limit rod 44, it is necessary to reduce the rotation of the fastening parts along the axis of the movable rod 3 during the sliding of the movable rod 3 and maintain a relatively fixed state. The two end surfaces of the main matching strip 2 along the length direction are provided with working grooves 25, which are connected with the receiving groove 21, and the working groove 25 covers the receiving groove 21, and the wall surface in the working groove 25 adjacent to the hook matching groove 222 is named as the first guide inner wall 251, and there is a boundary line between the first guide inner wall 251 and the inner bottom surface of the working groove 25, and the length direction of the boundary line is parallel to the length direction of the cross section of the hook matching groove 222, and the wall surface in the working groove 25 adjacent to the end of the displacement groove 221 away from the hook matching groove 222 is named as the second guide inner wall 252, and there is also a boundary line between the second guide inner wall 252 and the inner bottom surface of the working groove 25, and the length direction of the boundary line is consistent with the length direction of the cross section of the displacement groove 221 away from the end of the hook matching groove 222; both ends of the movable rod 3 in the length direction are fixedly connected with movable blocks 34, and the movable blocks 34 are arranged in a right-angled trapezoidal shape along the cross section perpendicular to the length direction of the movable rod 3; when the movable rod 3 When the displacement slot 221 moves away from the hooking slot 222, the side of the movable block 34 close to the right-angle waist of its cross-section fits with the second guide inner wall 252; when the movable rod 3 moves in the hooking slot 222, the side of the movable block 34 close to the oblique waist of its cross-section fits with the first guide inner wall 251.

[0054] Specifically, the movable blocks 34 are arranged at both ends of the movable rod 3 in the length direction, and the cross section of the movable block 34 is a right-angled trapezoid, and the side surface of the movable block 34 close to the lower bottom of the cross section faces the direction of the notch of the storage groove 21, and the side surface of the movable block 34 close to the right-angle waist is limited to be parallel to the second guide inner wall 252, and the side surface of the movable block 34 close to the oblique waist of the cross section is limited to be parallel to the first guide inner wall 251. Therefore, when the movable rod 3 is slid on the end of the cross section of the displacement groove 221 away from the hook groove 222, the side surface of the movable block 34 close to the right-angle waist can be made to fit with the second guide inner wall 252. When the movable rod 3 is slid on the hook groove 222, the side surface of the movable block 34 close to the oblique waist of its cross section can be fitted with the first guide inner wall 251. Due to the limitation of the surface constraint, the self-rotation of the movable rod 3 can be reduced in the process of sliding the movable rod 3 in the guide groove 22, and the rotational deviation of the buckle can be reduced simultaneously, thereby improving the effectiveness of the buckling connection between the buckling opening 33 of the buckle and the limit rod 44.

[0055] In order to facilitate the installation or testing process, the movable rod 3 can be moved in a variety of ways. The movable groove 41 is received in the working groove 25, and the end surface of the movable block 34 away from the movable rod 3 is provided with a gripping groove 35, so that the user can insert the gripping groove 35 of the movable block 34 by using a rod or other auxiliary member to slide the movable block 34 and drive the movable rod 3 to slide at the same time.

[0056] After the movable rod 3 is slid along the track direction of the cross section of the guide groove 22 until the snap-fitting opening 33 of the snap-fitting piece is snap-fitted with the limiting rod 44 of the auxiliary matching strip 4, the movable limiting piece can be used to limit the movement of the movable rod 3 and maintain the state of good snap-fitting connection between the snap-fitting opening 33 and the limiting rod 44. The working groove 25 is connected to the side of the main matching strip 2 near the notch of its receiving groove 21, and the two end faces of the auxiliary matching strip 4 along the length direction are provided with a sink groove 43, which is connected to the side of the auxiliary matching strip 4 near the notch of its movable groove 41; when the main matching strip 2 and the auxiliary matching strip 4 are fitted, and the notch of the receiving groove 21 is directly opposite to the notch of the movable groove 41, the working groove 25 of the main matching strip 2 is connected to the sink groove 43 of the auxiliary matching strip 4. The movable stopper includes a stopper 5. When the movable rod 3 moves to the end of the hook groove 222 away from the displacement groove 221, the stopper 5 is simultaneously plugged into the mutually connected position between the storage groove 21 and the sink groove 43, and the stopper 5 is simultaneously abutted against the inner wall of the sink groove 43, the inner wall of the working groove 25, and the outer peripheral surface of the movable block 34. Thus, by providing the stopper 5 and utilizing the stopper effect of the stopper 5, the stopper 5 is simultaneously abutted against the inner wall of the sink groove 43, the inner wall of the working groove 25, and the outer peripheral surface of the movable block 34, and the movable rod 3 is located at the end of the hook groove 222 away from the displacement groove 221, so that the stopper 5 is kept relatively fixed, and the buckle opening 33 and the stopper rod 44 are kept relatively fixed.

[0057] In order to improve the stability of the movable rod 3 during sliding, thereby reducing the possibility of jamming due to one end sliding. The storage groove 21 is integrally connected with a partition 23 in the middle of the length direction of the main matching strip 2, and the guide groove 22 is set through the partition 23. The side of the main matching strip 2 is penetrated by a working channel in the direction of the partition 23. The working channel penetrates the cross section of the guide groove 22, and the working channel is directly opposite to the center of gravity of the movable rod 3. Therefore, the user can use a rod or other auxiliary part to insert the movable channel 24 and push the center of gravity of the movable rod 3 to slide the movable rod 3 along the trajectory direction of the cross section of the guide groove 22 to the end of the hook groove 222 away from the displacement groove 221, thereby realizing the function of the buckling opening 33 of the buckle and the limit rod 44 being buckled and connected, and reducing the possibility of jamming of the movable rod 3 during sliding.

[0058] In order to facilitate the sliding of the movable rod 3 on the guide groove 22 through the movable channel 24, the assembled wood-plastic surface wall panel of the present invention also includes an extension rod 6 with a fork block 61 fixedly connected at one end, and the working channel is for the extension rod 6 and its fork block 61 to be inserted, and the fork of the fork block 61 is plugged and adapted with the outer peripheral surface of the movable rod 3. Therefore, when the user slides the movable rod 3, the fork block 61 at one end of the extension rod 6 can be inserted into the movable channel 24 and plugged with the movable rod 3, thereby driving the movable rod 3 to slide in the track direction of the cross section of the guide groove 22, thereby achieving the beneficial effect of stable sliding.

[0059] In order to realize the function of detachable connection between the main matching strip 2 and the wood plastic board 1, and the function of detachable connection between the connecting piece of the auxiliary matching strip 4 and the wood plastic strip, and realize the universality of detachable connection between the connecting piece of the auxiliary matching strip 4 and the main matching strip 2 and the wood plastic board 1. Matching grooves 13 are provided on two opposite sides of the wood plastic board 1. The matching grooves 13 extend through the wood plastic board 1 in the direction close to the flange 11, but do not penetrate the end face of the wood plastic board 1 close to the strip groove, so as to facilitate the support during the installation process, and the cross section of the matching groove 13 is dovetail-shaped. The side of the main matching strip 2 away from the notch of the receiving groove 21 is fixedly connected with a first matching strip 26, and the length direction of the first matching strip 26 is consistent with the length direction of the main matching strip 2. The connecting piece includes a second matching strip 42 fixedly connected to the side of the auxiliary matching strip 4, and the length of the second matching strip 42 is consistent with the length direction of the auxiliary matching strip 4. The first matching strip 26 and the second matching strip 42 are both plugged and adapted to the matching groove 13.

[0060] Based on the above-mentioned overall structure of the assembled wood-plastic wallboard, the present invention also claims protection for an installation method of the assembled wood-plastic wallboard, comprising the following steps:

[0061] ①Wall installation preparation: clean the wall, drill holes on the cleaned wall with an electric drill, and then lay the WPC keel on the cleaned wall, so that the length direction of the WPC keel is perpendicular to the horizontal plane, and use expansion screws to connect and fix the WPC keel to the wall;

[0062] ②Installation at the corner of the wall:

[0063] 2.1.

The outer corner of the main matching strip 2 is close to each other, and the receiving groove 21 of the main matching strip 2 is aligned with the movable groove 41 of the auxiliary matching strip 4, and the flanges 11 of the two wood-plastic boards 1 are kept facing upward. Then, the fork block 61 is inserted into the working channel by using the extension rod 6, and the fork of the fork block 61 is plugged into the outer periphery of the movable rod 3. Then, the movable rod 3 is moved toward the end of the hook matching groove 222 along the L-shaped direction of the guide groove 22 by using the extension rod 6. When the movable rod 3 moves to the hook matching groove 222 away from the displacement groove 221, When the end position of the main mating strip 2 is reached, the mating opening 33 between the push strip 31 and the mating strip 32 is mated with the limiting rod 44, and the mating limiting block 5 is inserted into the communication position between the working groove 25 of the main mating strip 2 and the sink groove 43 of the auxiliary mating strip 4 to limit the movement of the movable block 34. Then, the flange 11 of the wood-plastic board 1 is connected to the wood-plastic keel by screws, and the nut of the screw is flush with the surface of the flange 11, and then the wood-plastic board 1 is installed upward in sequence, and the strip groove of the wood-plastic board 1 at the top is mated with the flange 11 of the adjacent wood-plastic board 1 at the bottom.

[0064] 2.2. When the corner of the wall is an inner corner: select one of the second matching strips 42 of the secondary matching strip 4 to be plugged into the matching groove 13 of the wood plastic board 1, so that the notch of the active groove 41 of the secondary matching strip 4 faces the side close to the decorative surface of the wood plastic board 1, and then plug and match the first matching strip 26 of the main matching strip 2 with the matching groove 13 of the other wood plastic board 1, and then lay the two wood plastic boards 1 on both sides of the outer corner of the wall respectively, so that the main matching strip 2 and the secondary matching strip 4 are against each other, and approach the position close to the inner corner of the wall, and at the same time, make the storage groove 21 of the main matching strip 2 face the active groove 41 of the secondary matching strip 4, and keep the flanges 11 of the two wood plastic boards 1 facing upward, and then according to the above-mentioned installation method, the buckle mouth 33 of the main matching strip 2 of one of the wood plastic boards 1 at the same inner corner is buckled and connected with the limit strip of the secondary matching strip 4 of the other wood plastic board 1, and install the wood plastic boards 1 one by one from bottom to top;

[0065] ③ Wall main body installation: After the wood plastic board 1 at the corner of the wall is installed, the wood plastic board 1 is further installed from the wall near the corner of the wall in the direction away from the corner of the wall.

In the process of laying the wood plastic board 1, the strip groove of the upper wood plastic board 1 is plugged with the flange 11 of the lower wood plastic board 1, and after the strip groove of each wood plastic board 1 is plugged with the flange 11 of the lower wood plastic board 1, the flange 11 of the wood plastic board 1 is locked and connected with the corresponding wood plastic keel by screws, and the nut of the screw is flush with the surface of the flange 11, and the wood plastic board 1 is installed in the direction away from the corner of the wall in the above manner, and the wood plastic board 1 covers the original cavity to form a new wood plastic wall, thereby completing the installation operation of the wood plastic board 1.

[0066] Specifically, based on the installation method of the assembled wood-plastic wallboard, the method is mainly divided into three processes: wall installation preparation process, wall corner installation process, and wall main body installation process. In the wall corner installation process, there are two installation conditions: inner corner and outer corner. Thus, the assembled wood-plastic wallboard of the present invention can be installed on the wall as a whole, and it is also suitable for installation of different corner types, thereby replacing the operation of using right-angle bars for corner auxiliary installation in the prior art, and reducing the situation of fixing glue and screwing at the corner position, so as to stabilize the overall structure and beautify the overall appearance. At the same time, it should be further explained that, since the installation method of the present invention mainly starts from the corner position, and then installs the wood-plastic board 1 from the corner position to the middle position of the wall, when the wood-plastic board 1 is too long in the middle position, the wood-plastic board 1 can be cut in time and then assembled, thereby reducing the scientific installation operation and the overall wall surface.

[0067] The implementation methods of the present invention are not limited to this. According to the above content of the present invention, using common technical knowledge and customary means in the field, without departing from the above basic technical ideas of the present invention, the present invention can also make other various forms of modification, replacement or combination, all of which fall within the scope of protection of the present invention.
