Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated building materials, and particularly relates to a reversible installation system for prefabricated decoration wall panels. Background Art

[0002] A wall panel, now referring to a building material, is a building structure with a load-bearing system composed of walls and floors. The load-bearing walls of the wall panel structure can be made of bricks, blocks, precast or cast-in-situ concrete, and can be divided into three categories according to the different materials used and construction methods: mixed structure, prefabricated large panel structure, and cast-in-situ wall panel structure; prefabricated wall panels refer to transferring a large amount of on-site operation work in the traditional construction method to the factory, fabricating building wall panels in the factory, transporting them to the building construction site, and assembling and installing them on-site through reliable connection methods.

[0003] Problems existing in the prior art:

[0004] Most of the existing prefabricated decoration wall panels adopt a snap-in installation method. First, grooves need to be made on the edges of the wall panels, then the clamping strips are installed, and finally, the grooves are aligned with the clamping strips during installation. This installation method requires the wall panels to be inserted from one end and slid to the designated position. The installation process pays great attention to the accuracy of the installation positions of the keels and the clamping strips. Moreover, the traditional clamping strips adopt a fixed installation method. Once their installation positions deviate, it will directly cause the wall panels to fall off or the wall panels cannot be installed. Therefore, it highly depends on the skills of the workers and their ability to make zero mistakes. In addition, such wall panels are not easy to disassemble. When a wall panel needs to be replaced due to damage, either the adjacent wall panels need to be disassembled, or the single wall panel is directly demolished violently. The first method increases the workload of disassembly, thereby increasing the labor cost, and may also cause damage to the adjacent wall panels. The second method directly damages the original wall panel, which is not conducive to the secondary utilization of materials, and the installation of a single wall panel is easily restricted by the clamping strips, so it is not advisable. Summary of the Invention

[0005] The purpose of the present invention is to provide a reversible installation system for prefabricated decoration wall panels, which can make the distance between the vertical keels and the horizontal keels adjustable flexibly, with a simple adjustment structure and convenient operation. It can also complete the disassembly of a single wall panel without affecting or damaging the surrounding wall panels, and the angle of the wall panel is also adjustable.

[0006] The technical solution adopted by the present invention is specifically as follows:

[0007] A reversible installation system for prefabricated decoration wall panels includes a decorative wall panel and a keel structure for installing the decorative wall panel. The keel structure is composed of vertical keels and horizontal keels. The vertical keels are longitudinally and equidistantly installed on the surface of the building wall, and the horizontal keels are horizontally and equidistantly installed outside the vertical keels. The decorative wall panel is detachably installed outside the horizontal keels;

[0008] Moreover, expansion bolts are inserted at the intersections of the vertical keels and the horizontal keels inside the building wall, and the vertical keels and the horizontal keels are fixed by fixing bolts screwed into the expansion bolts. An adjustable frame is arranged between the intersections of the vertical keels and the horizontal keels to cooperate with the fixing bolts to adjust the distance between the vertical keels and the horizontal keels. The decorative wall panel is installed on the outer side of the horizontal keel through reversible hanging parts assembled on the back;

[0009] The side wall of the horizontal keel is equidistantly penetrated with bolt holes II, and middle clamping grooves are equidistantly penetrated between adjacent bolt holes II on the side wall of the horizontal keel. Angle clamping grooves are arranged on both the upper and lower sides of the middle clamping groove on the side wall of the horizontal keel;

[0010] The reversible hanging part includes a vertical groove shell. A clamping frame for clamping the horizontal keel is integrally fixed on the side wall of the vertical groove shell. Inner clamping blocks are symmetrically and slidably assembled inside the top and bottom sides of the end of the clamping frame. The inner clamping blocks penetrate through the corresponding angle clamping grooves and a second spring is connected between the inner clamping blocks and the inner wall of the clamping frame;

[0011] A middle pipe is integrally fixed in the middle of the clamping frame. 90-degree guiding grooves are arranged on both sides of the inner wall of the middle pipe. An inner sliding rod for penetrating through the middle clamping groove is movably inserted into the middle pipe. Sliders movably embedded in the 90-degree guiding grooves are fixed on the outer walls of both ends of the inner sliding rod. The other end of the inner sliding rod is rotatably connected with a wall abutting rod, and a pressing plate is fixed on the outer wall of the inner sliding rod near the wall abutting rod and outside the middle pipe at the same time.

[0012] The inner sliding rod is supported by a magnetic material and lubricating oil is smeared between the inner sliding rod and the inner wall of the middle pipe.

[0013] Horizontal groove frames are fixedly installed on both sides of the back of the decorative wall panel through screws. A vertical sliding plate is slidably assembled inside the vertical groove shell. A groove inner slider is fixed on the outer wall of the vertical sliding plate, and the groove inner slider is slidably embedded inside the horizontal groove frame.

[0014] Side teeth are equidistantly fixed on the side wall of the vertical sliding plate. A side extension pipe is integrally fixed on the side wall of the vertical groove shell. A pull plate is slidably assembled on one side of the vertical groove shell. An end tooth rod penetrating through the side extension pipe and meshing with the side teeth is integrally fixed at one end of the pull plate, and a third spring is sleeved on the outer surface of the end tooth rod and inside the side extension pipe.

[0015] Bolt holes I are equidistantly penetrated on the surface of the vertical keel, and nut shells are fixedly arranged at positions corresponding to the bolt holes I on the back of the vertical keel, and nuts are slidably installed inside the nut shells.

[0016] A clamping frame is fixedly arranged on the inner wall of the transverse keel at the position corresponding to the second bolt hole, a bolt hole three is penetrated through the middle of the clamping frame, side groove rails are symmetrically arranged on both sides of the top and bottom ends of the clamping frame, and a middle groove rail is fixedly arranged in the middle of the top and bottom ends of the clamping frame.

[0017] A bolt hole four is provided through the middle of the adjustable frame, a spring one is provided between the side wall of the bolt hole four and the side wall of the clamping frame, side groove rods are symmetrically provided on both sides of the top and bottom ends of the adjustable frame, and a middle plug plate is fixedly provided in the middle of the top and bottom ends of the adjustable frame.

[0018] The side slot rods are all slidably inserted into the side slot rails, and the middle inserting plates are all slidably inserted into the middle slot rails.

[0019] One end of the middle groove rail located at the top is fixedly connected with a paddle, and the upper surface of the middle plug board located at the top is fixedly connected with elastic sheets at equal distances.

[0020] The bolt hole one, the bolt hole two, the bolt hole three and the bolt hole four are on the same axis, the fixing bolt passes through the bolt hole two, the bolt hole three, the bolt hole four and the bolt hole one in sequence and is used to make the clamping frame close to the adjustable frame, and the fixing bolt is screwed with the nut at the same time.

[0021] The technical effects achieved by the present invention are:

[0022] (1) According to the present invention, when it is found that the distance between a horizontal purlin and the wall surface is different due to the uneven wall surface or the two horizontal purlins are not in the vertical plane, it is only necessary to rotate the fixing bolt to adjust the distance between the clamping frame and the adjustable frame, and finally the position of the horizontal purlin is changed accordingly. This process changes the fixed assembly relationship between the traditional vertical purlins and the horizontal purlins, so that the spacing between the two has the advantage of flexible and adjustable spacing. In addition, the fixing bolts can not only fix the vertical purlins and the horizontal purlins, but also adjust the spacing between the vertical purlins and the horizontal purlins, making the spacing adjustment work between the vertical purlins and the horizontal purlins simpler and faster, and ensuring that the finished surface of the adjacent decorative wall panels is flat and not staggered.

[0023] (2) In the present invention, when adjusting the position of an entire transverse keel, when relative movement occurs between the middle plug plate and the middle groove rail, the paddle will contact the elastic sheet at the corresponding position, and the elastic sheet will make a sound due to vibration when resetting. At this time, the number of pronunciations at different positions can be used to ensure that the transverse keel moves without tilting or turning. The moving distance of the transverse keel at different points can be determined based on the number of pronunciations, which further facilitates the adjustment of the transverse keel.

[0024] (3) In the present invention, this reversible hanging and mounting structure, while achieving the effect of seamless splicing and installation of decorative wall panels, also has the characteristics of being easy to disassemble and leaving no marks during disassembly. Compared with the traditional snap-in installation method for wall panels, this method does not require grooving the edges of the wall panels, and at the same time, it will not damage the edges of the wall panels when unloading the wall panels. In addition, each decorative wall panel can be disassembled independently without affecting or damaging the surrounding wall panels, ensuring the integrity of the removed wall panels and facilitating the secondary utilization of materials. The process of disassembling the wall panels is simple and only requires cooperation with a strong magnet to directly complete the disassembly.

[0025] (4) In the present invention, when it is found that the decorative wall panel is skewed, only need to pull the pull plate on the corresponding side at this time. First, separate the end tooth rod from the side teeth and compress the spring three, and then straighten the decorative wall panel. After the adjustment is completed, release the pull plate to make the end tooth rod and the side teeth mesh again to fix the decorative wall panel. During this process, at the same time, this decorative wall panel has the advantage of being adjustable, ensuring the precise installation of the decorative wall panel, and the adjustment process is simple and fast.

[0036] In order to make the purpose and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation modes of the present invention, and does not strictly limit the specific protection scope claimed by the present invention.

[0037] As Figure 1-8 shown, a reversible installation system for prefabricated decoration wall panels includes a decorative wall panel 3 and a keel structure for installing the decorative wall panel 3. The keel structure is composed of a vertical keel 1 and a horizontal keel 2. The vertical keels 1 are longitudinally and equidistantly installed on the surface of the building wall, and the horizontal keels 2 are horizontally and equidistantly installed outside the vertical keels 1. The decorative wall panel 3 is detachably installed outside the horizontal keel 2.

[0038] Referring to the attached Figure 2 , and expansion bolts 4 are inserted into the building wall corresponding to the intersections of the vertical keels 1 and the horizontal keels 2. The vertical keels 1 and the horizontal keels 2 are fixed by fixing bolts 6 screwed into the inside of the expansion bolts 4. An adjustable frame 5 for cooperating with the fixing bolts 6 to adjust the distance between the vertical keels 1 and the horizontal keels 2 is arranged between the intersections of the vertical keels 1 and the horizontal keels 2, and the decorative wall panel 3 is installed outside the horizontal keel 2 through a reversible hanging part 7 assembled on the back.

[0039] According to the above structure, first drill holes at the corresponding positions on the building wall, insert expansion bolts 4 into each drill hole, then install the vertical keels 1 and the horizontal keels 2, and complete the fixation of the two by inserting the fixing bolts 6 into the inside of the expansion bolts 4. Then install the reversible hanging part 7 at the corresponding position on the back of the decorative wall panel 3, and then install the decorative wall panel 3 on the surface of the horizontal keel 2 through the reversible hanging part 7, thus completing the installation work of the decorative wall panel 3.

[0040] Embodiment 1

[0041] Refer to the attached Figure 1 and Figure 3 , on the surface of the vertical keel 1, bolt holes 101 are equidistantly and penetratingly formed, and nut shells 102 are fixedly arranged at the positions corresponding to the bolt holes 101 on the back surface of the vertical keel 1, and nuts 103 are slidably installed inside the nut shells 102.

[0042] Refer to the attached Figure 3 and Figure 4 , on the side wall of the horizontal keel 2, bolt holes 203 are equidistantly and penetratingly formed, pressing frames 204 are fixedly arranged at the positions corresponding to the bolt holes 203 on the inner wall of the horizontal keel 2, bolt holes 205 are penetratingly formed in the middle of the pressing frames 204, side groove rails 206 are symmetrically arranged on both sides of the top and bottom ends of the pressing frames 204, and middle groove rails 207 are fixedly arranged in the middle of the top and bottom ends of the pressing frames 204.

[0043] Refer to the attached Figure 4 and Figure 5 , a bolt hole 501 is penetratingly formed in the middle of the adjustable frame 5, a first spring 502 is arranged between the side wall of the bolt hole 501 and the side wall of the pressing frame 204, side groove rods 503 are symmetrically arranged on both sides of the top and bottom ends of the adjustable frame 5, and middle insertion plates 504 are fixedly arranged in the middle of the top and bottom ends of the adjustable frame 5. The side groove rods 503 are all slidably inserted into the side groove rails 206, and the middle insertion plates 504 are all slidably inserted into the middle groove rails 207. The bolt holes 101, 203, 205 and 501 are on the same axis. The fixing bolt 6 sequentially penetrates through the bolt hole 203, the bolt hole 205, the bolt hole 501 and the bolt hole 101 and is used to make the pressing frame 204 approach the adjustable frame 5. The fixing bolt 6 is simultaneously screwed with the nut 103.

[0044] According to the above structure, during the assembly of the vertical keel 1 and the horizontal keel 2, an adjustable bracket 5 is clamped at the intersection of the vertical keel 1 and the horizontal keel 2. Then, the fixing bolt 6 penetrates through the vertical keel 1 and the horizontal keel 2 and is screwed with the expansion bolt 4 in the wall. One end of the fixing bolt 6 is blocked by the pressing bracket 204. Therefore, during the rotation of the fixing bolt 6, the pressing bracket 204 will continuously approach the adjustable bracket 5 and compress the first spring 502. At the same time, the side groove rod 503 will be inserted into the inner part of the side groove rail 206, and the middle insertion plate 504 will be inserted into the inner part of the middle groove rail 207. When it is found that due to the uneven wall surface, the distance between a horizontal keel 2 and the wall surface is different or the two horizontal keels 2 are not in the same vertical plane, at this time, only need to rotate the fixing bolt 6 to adjust the distance between the pressing bracket 204 and the adjustable bracket 5. Under the action of the first spring 502 in the compressed state, the adjustable bracket 5 will closely adhere to the outer wall of the vertical keel 1. During the process of the pressing bracket 204 moving away from the adjustable bracket 5, the position of the horizontal keel 2 also changes correspondingly. In this process, the traditional fixed assembly relationship between the vertical keel 1 and the horizontal keel 2 is changed, making the distance between the two adjustable flexibly. In addition, the fixing bolt 6 can not only fix the vertical keel 1 and the horizontal keel 2, but also adjust the distance between the vertical keel 1 and the horizontal keel 2, making the distance adjustment work between the vertical keel 1 and the horizontal keel 2 simpler and faster, ensuring that the finished surfaces of adjacent decorative wall panels 3 are flat and without intersection.

[0045] Refer to the attached Figure 4 and Figure 5 , one end of the middle groove rail 207 located above is fixedly connected with a dial 208, and elastic sheets 505 are fixedly connected at equal intervals on the upper surface of the middle insertion plate 504 located above.

[0046] According to the above structure, when adjusting the position of an entire horizontal keel 2, when relative movement occurs between the middle insertion plate 504 and the middle groove rail 207, the dial 208 will contact the elastic sheet 505 at the corresponding position. The elastic sheet 505 will make a sound due to vibration when resetting. At this time, the movement of a horizontal keel 2 can be ensured without tilting or turning according to the number of pronunciation times at different positions. According to the number of pronunciation times, the moving distance of a horizontal keel 2 at different points can be determined, which further facilitates the position adjustment work of the horizontal keel 2.

[0047] The working principle of the present invention is as follows: during the assembly of the vertical keel 1 and the horizontal keel 2, the adjustable frame 5 is clamped at the intersection of the vertical keel 1 and the horizontal keel 2, and then the fixing bolt 6 is passed through the vertical keel 1 and the horizontal keel 2 and screwed with the expansion bolt 4 in the wall. One end of the fixing bolt 6 is blocked by the clamping frame 204. Therefore, during the rotation of the fixing bolt 6, the clamping frame 204 will continuously approach the adjustable frame 5 and squeeze the spring 1 502. At the same time, the side groove rod 503 will be inserted into the side groove rail 2. 06, and the middle insert plate 504 will be inserted into the middle groove rail 207. When it is found that the distance between a horizontal keel 2 and the wall is different due to the uneven wall surface or the two horizontal keels 2 are not in the vertical plane, it is only necessary to rotate the fixing bolt 6 to adjust the distance between the clamping frame 204 and the adjustable frame 5. Under the action of the spring 502 in the compressed state, the adjustable frame 5 will be close to the outer wall of the vertical keel 1. When the clamping frame 204 moves away from the adjustable frame 5, the position of the horizontal keel 2 will also change accordingly.

[0048] When adjusting the position of an entire transverse keel 2, when relative movement occurs between the middle plug plate 504 and the middle groove rail 207, the paddle 208 will contact the elastic sheet 505 at the corresponding position, and the elastic sheet 505 will make a sound due to vibration when resetting. At this time, the number of sounds at different positions can be used to ensure that a transverse keel 2 moves without tilting or turning.

[0049] Embodiment 2

[0050] See attached Figure 3 A middle slot 202 is formed in the side wall of the transverse keel 2 and is equidistantly disposed between two adjacent bolt holes 203 . Angle slots 201 are formed in the side wall of the transverse keel 2 and are disposed on both upper and lower sides of the middle slot 202 .

[0051] See attached Figure 6 and Figure 7 The reversible mounting part 7 includes a vertical slot shell 701, and the side wall of the vertical slot shell 701 is integrally fixed with a bracket 702 for clamping the horizontal keel 2. The top and bottom ends of the bracket 702 are symmetrically slidably assembled with internal blocks 703. The internal blocks 703 pass through the corresponding corner slots 201 and are connected to the inner wall of the bracket 702 by a spring 2 704.

[0052] See attached Figure 7 and Figure 8A middle tube 705 is fixedly arranged in an integrated manner in the middle of the card frame 702, and 90-degree guide grooves 706 are opened on both sides of the inner wall of the middle tube 705. An inner slide bar 707 for penetrating the middle card slot 202 is movably inserted inside the middle tube 705, and sliders 708 movably embedded in the 90-degree guide grooves 706 are fixedly arranged on the outer walls on both sides of one end of the inner slide bar 707. The other end of the inner slide bar 707 is rotatably connected to a wall-proof rod 710, and a stop plate 709 is fixedly arranged on the outer wall of one end of the inner slide bar 707 close to the wall-proof rod 710 and at the same time located on the outside of the middle tube 705. The inner slide bar 707 is supported by magnetic material and lubricating oil is applied between it and the inner wall of the middle tube 705.

[0053] When the bracket 702 is in the process of being clamped with the cross keel 2, the inner clamping block 703 moves to the position of the corner clamping slot 201, and the inner clamping block 703 will be pushed out and clamped into the corner clamping slot 201 under the action of the second spring 704. Before that, the inner slide bar 707 will carry the wall-holding rod 710 and the horizontal retaining plate 709 to pass through the middle clamping slot 202 first, and before the bracket 702 clamps the cross keel 2, the wall-holding rod 710 first contacts the wall surface and is blocked. When the bracket 702 continues to move, the inner slide bar 707 will move relative to the middle tube 705 at the same time and shrink into the middle tube 705 accordingly. In this process, since the slider 708 is embedded in the 90-degree guide groove 706, the inner slide bar 707 simultaneously drives the retaining plate 709 to rotate. When the inner clamping block 703 is clamped into the corner clamping slot 201, Figure 7 As shown, the push plate 709 simultaneously completes the rotation of 90 degrees and is close to the inner clamping block 703, and then the installation of the decorative wall panel 3 is completed. When the decorative wall panel 3 needs to be removed, a strong magnet is used to approach the inner sliding rod 707. Under the strong suction force, the inner sliding rod 707 will continue to retract into the middle tube 705, and the inner clamping block 703 will be squeezed by the push plate 709 and retracted into the bracket 702 and disengaged from the corner clamping groove 201. At this time, the decorative wall panel 3 can be removed. After the bracket 702 is separated from the horizontal keel 2, the push plate 709 is still blocked by the horizontal keel 2. At this time, it is only necessary to continue to move the decorative wall panel 3 to make the inner sliding rod 707 extend from the inside of the middle tube 705, and then Under the guidance of the 90-degree guide groove 706, the stop plate 709 will rotate 90 degrees and eventually pass through the middle slot 202. This reversible hanging part 7 structure, while achieving the effect of seamless splicing and installation of the decorative wall panel 3, also has the characteristics of easy disassembly and traceless disassembly. Compared with the traditional wall panel clip-on installation method, this method does not require grooving on the edge of the wall panel, and will not damage the edge of the wall panel when unloading the wall panel. In addition, each decorative wall panel 3 can be disassembled individually without affecting and damaging the surrounding wall panels, thereby ensuring the integrity of the disassembled wall panels and facilitating the secondary use of materials. The wall panel disassembly process is simple, and it can be directly disassembled with the help of strong magnets.

[0054] Refer to the attached Figure 6 and Figure 8 , on both sides of the back of the decorative wall panel 3, horizontal groove frames 301 are fixedly installed by screws. Inside the vertical groove shell 701, a vertical sliding plate 711 is assembled in a sliding manner. On the outer wall of the vertical sliding plate 711, an in-groove slider 713 is fixedly arranged, and the in-groove slider 713 is slidably embedded and installed inside the horizontal groove frame 301.

[0055] Refer to the attached Figure 8 , on the side wall of the vertical sliding plate 711, side teeth 712 are fixedly arranged at equal intervals. On the side wall of the vertical groove shell 701, a side extension tube 714 is integrally fixed. On one side of the vertical groove shell 701, a pull plate 715 is assembled in a sliding manner. At one end of the pull plate 715, an end tooth rod 716 that penetrates through the side extension tube 714 and is used to engage with the side teeth 712 is integrally fixed. A third spring is sleeved on the outer surface of the end tooth rod 716 and inside the side extension tube 714.

[0056] According to the above structure, after the installation of the decorative wall panel 3 is completed, if the decorative wall panel 3 is skewed due to the deviation of the installation position of the horizontal groove frame 301, at this time, only need to pull the pull plate 715 on the corresponding side, first separate the end tooth rod 716 from the side teeth 712 and compress the third spring, and then straighten the decorative wall panel 3. During the adjustment process, the in-groove slider 713 will move inside the corresponding horizontal groove frame 301 to cooperate with the adjustment of the decorative wall panel 3. After the adjustment is completed, release the pull plate 715 to make the end tooth rod 716 re-engage with the side teeth 712 to fix the decorative wall panel 3. In this process, at the same time, the decorative wall panel 3 has the advantage of being adjustable, ensuring the precise installation of the decorative wall panel 3.

[0057] The working principle of the present invention is as follows: During the installation of the decorative wall panel 3, that is, during the clamping process of the clamping frame 702 and the horizontal keel 2, when the inner clamping block 703 moves to the position of the corner clamping groove 201, under the action of the second spring 704, the inner clamping block 703 will be ejected and clamped into the inner part of the corner clamping groove 201. Before that, the inner sliding rod 707 will carry the wall abutting rod 710 and the horizontal abutting plate 709 and pass through the middle clamping groove 202 first. Before the clamping frame 702 clamps the horizontal keel 2, the wall abutting rod 710 will first contact the wall surface and be blocked. During the continuous movement of the clamping frame 702, relative movement will occur between the inner sliding rod 707 and the middle tube 705 at the same time and the inner sliding rod 707 will correspondingly retract into the middle tube 705. During this process, since the slider 708 is embedded in the 90-degree guiding groove 706, the inner sliding rod 707 will drive the abutting plate 709 to rotate simultaneously. When the inner clamping block 703 is clamped into the inner part of the corner clamping groove 201, as Figure 7As shown, the bottom plate 709 rotates 90 degrees and simultaneously approaches the inner clamping block 703, and then the installation of the decorative wall panel 3 is completed. When it is necessary to disassemble the decorative wall panel 3, a powerful magnet is used to approach the inner sliding rod 707. Under the strong suction force, the inner sliding rod 707 will continue to retract into the inner part of the middle pipe 705, and the inner clamping block 703 will be respectively retracted into the clamping frame 702 under the extrusion of the bottom plate 709 and separated from the corner card slot 201. At this time, the decorative wall panel 3 can be removed. After the clamping frame 702 is separated from the horizontal keel 2, the bottom plate 709 is still blocked by the horizontal keel 2. At this time, only need to continue to move the decorative wall panel 3 to make the inner sliding rod 707 extend out from the inner part of the middle pipe 705, and then under the guidance of the 90-degree guiding groove 706, the bottom plate 709 will rotate 90 degrees and finally can pass through the middle card slot 202;

[0058] After the installation of the decorative wall panel 3 is completed, if the decorative wall panel 3 is skewed due to the deviation of the installation position of the horizontal groove frame 301, at this time, only need to pull the pull plate 715 on the corresponding side, first separate the end tooth rod 716 from the side tooth 712 and squeeze the spring three, and then straighten the decorative wall panel 3. During the adjustment process, the slider 713 in the groove will move inside the corresponding horizontal groove frame 301 to cooperate with the adjustment of the decorative wall panel 3.
