Description

Technical Field

[0001] This application relates to the field of building materials technology, and more specifically, to integrated prefabricated wall panels and wall panels for integrated prefabricated wall panels. Background Technology

[0002] With the upgrading of decoration technology, prefabricated decoration has become increasingly popular. Prefabricated decoration allows the dimensions of the building space to be pre-processed in the factory, and then the pre-processed building materials can be transported to the site for direct assembly. This decoration method makes decoration and installation simpler and improves decoration efficiency.

[0003] Taking wall decoration as an example, wall panels are prefabricated in the factory, and on-site workers only need to install leveling components on the wall and then fix the prefabricated wall panels onto the leveling components. However, in practical applications, it has been found that this traditional prefabricated wall decoration method has the following problems: First, the leveling components occupy extra space and are labor-intensive and time-consuming, resulting in higher installation costs; second, there are gaps between the wall panels and the wall, which can easily lead to hollow spots in the wall panels; third, the wall panels are spliced ​​together, and individual wall panels cannot be disassembled later, making subsequent maintenance very difficult. Summary of the Invention

[0004] The purpose of this application is to provide integrated prefabricated wall panels and wall panels for integrated prefabricated wall panels, so as to solve the technical problems of traditional prefabricated wall decoration, such as the space occupied by leveling components, the easy occurrence of hollowing of wall panels, and the inability to disassemble wall panels individually.

The bolt mounting groove and the second transverse groove are arranged opposite to each other. The partition wall has a through fixing hole along the thickness direction. The through fixing hole penetrates the bottom surface of the bolt mounting groove and the second transverse groove respectively. The integrated prefabricated wall panel also includes: two angle irons, one side of which has an expansion bolt mounting hole and the other side has a through bolt mounting hole. The two angle irons are fixed to the floor and ceiling of the building space by expansion bolts passing through the expansion bolt mounting holes. The partition wall is fixedly connected to the two angle irons by through bolts passing through the through bolt mounting holes and through fixing holes. The two ends of the through bolts are located in the bolt mounting groove and the second transverse groove, respectively. One side of the angle iron is located in the first transverse groove and the other side of the angle iron is located in the second transverse groove.

[0016] The advantages of this application compared to the prior art are at least as follows: The integrated prefabricated wall panel replaces the traditional fixed wall with a strip partition wall. Since the two sides of the strip partition wall are flat, there is no need to level the wall, saving leveling components. This not only saves materials and installation costs but also reduces space occupation. Simultaneously, the wall panels, connected with expansion bolts and connectors, form a prefabricated wall panel, allowing the wall panels to be independently fixed in the wall panel mounting holes of the strip partition wall. Adjacent wall panels do not affect each other and can be disassembled individually, reducing the difficulty of later wall panel maintenance. Furthermore, the sound-absorbing pad sandwiched between the wall panel and the strip partition wall prevents noise generated by impact, overcoming the problem of hollow sounds when tapping traditional wall panels. Finally, the installation of the integrated prefabricated wall panel is very simple, and the wall panels are finished at the top and bottom, achieving a fully prefabricated decoration of the entire wall surface, ensuring both aesthetics and improving the overall decoration efficiency.

[0034] Please see Figures 1 to 11 This embodiment provides an integrated prefabricated wall panel, comprising: a strip partition wall 1, a wall top finishing piece 2, a wall panel 3, a sound-absorbing pad 4, a skirting board fixing piece 5, and a skirting board 6. The strip partition wall 1 is fixedly connected between the floor and ceiling of the building space. At least one side of the strip partition wall 1 in the thickness direction is flat and has wall panel mounting holes 11. The wall top finishing piece 2 includes a slot 21 with two opposing groove sidewalls 22 of different heights. The higher groove sidewall 22 is fixedly connected to the top of the strip partition wall 1, and the outer side of the groove bottom surface of the slot 21 abuts against the ceiling of the building space. One side of the wall panel 3 in the thickness direction is a decorative surface, and its end near the ceiling of the building space is inserted into the slot 21 of the wall top finishing piece 2. The back has pre-drilled wall panel connection holes 31. Connectors 7 and expansion bolts 8 are installed inside the wall panel connection holes 31. Connectors 7 include at least screws 71 and connecting rods 72. One end of the connecting rod 72 is connected to the screw 71. The expansion bolt 8 is a hollow cylinder with internal threads 81 on its inner wall. The internal threads 81 mate with the screw 71 and are threaded together. The outer wall of the hollow cylinder abuts against the inner wall of the wall panel connection hole 31 for secure fixing. The other end of the connecting rod 72 is inserted into the wall panel mounting hole 11 and glued to the partition wall 1. A sound-absorbing pad 4 is placed between the wall panel 3 and the partition wall 1. A skirting board fixing component 5 is fixedly connected to the decorative surface of the wall panel 3 near the ground. A skirting board 6 is detachably connected to the skirting board fixing component 5.

[0035] The installation steps for the above-mentioned integrated prefabricated wall panels are as follows:

[0036] Step 1: Vertically fix the partition wall 1 between the floor and the ceiling of the building space;

[0037] Step 2: Place the expansion bolt 8 into the wall panel connection hole 31;

[0038] Step 3: Align the screw 71 of the connector 7 with the expansion bolt 8, and rotate the connector 7 to make the screw 71 engage with the internal thread 81 of the expansion bolt 8, so that the connector 7 is fixedly connected to the wall panel 3.

[0039] Step 4: Inject an appropriate amount of structural adhesive into the wall panel mounting holes 11 of the partition wall 1;

[0040] Step 5: Fix the top edge trim 2 to the top of the panel partition 1 using fixing screws 71;

[0041] Step 6: Insert the upper end of the wall panel 3 into the slot 21 of the wall top finishing piece 2, and at the same time align the connector 7 with the wall panel mounting hole 11, insert it into the structural adhesive, and adjust the depth of the connector 7 in the structural adhesive according to the finished surface line.

[0042] Step 7: Fix the baseboard fastener 5 to the wall panel 3 with self-tapping screws, and finally install the baseboard 6 on the baseboard fastener 5.

[0043] Therefore, according to the technical solution provided by the integrated prefabricated wall panel, the strip partition wall 1 replaces the traditional fixed wall. Since the two sides of the strip partition wall 1 are flat, there is no need to level the wall, saving leveling components. This not only saves materials and installation costs, but also reduces space occupation. At the same time, the wall panel 3 is connected with the expansion bolt 8 and the connector 7 to form the wall panel 3 for the integrated prefabricated wall panel. The wall panel 3 can be independently fixed in the wall panel mounting hole 11 of the strip partition wall 1. Adjacent wall panels 3 do not affect each other and can be disassembled individually, reducing the difficulty of later maintenance of the wall panel 3. In addition, the sound-absorbing pad 4 sandwiched between the wall panel 3 and the strip partition wall 1 avoids the noise generated by the wall panel 3 due to impact, overcoming the problem of the hollow feeling when tapping the wall panel 3 of the traditional wall panel. Finally, the installation of the integrated prefabricated wall panel is very simple, and the wall panel 3 is also finished at the top and the ground, realizing the full prefabricated decoration of the entire wall, which not only ensures the aesthetics of the wall, but also improves the overall decoration efficiency of the wall.

[0044] Specifically, the shape of the panel partition 1 is preferably a cuboid or a cube. In practical applications, the fixing method of the panel partition 1 is not unique.

[0045] For example, in one embodiment, combined with Figures 3 to 7 For example, the partition wall 1 has a first transverse groove 12 on each end face in the height direction, and a second transverse groove 13 on one side of the thickness direction near the ground and the top surface. The second transverse groove 13 is connected to the first transverse groove 12. The partition wall 1 has a bolt mounting groove 14 on the other side of the thickness direction near the ground and the top surface. The bolt mounting groove 14 is arranged opposite to the second transverse groove 13. The partition wall 1 has a through fixing hole 15 along the thickness direction. The through fixing hole 15 passes through the bottom surface of the bolt mounting groove 14 and the second transverse groove 13 respectively. Correspondingly, the integrated prefabricated wall panel also includes: angle irons 9, of which there are two. One side of the angle iron 9 is provided with an expansion bolt mounting hole 91, and the other side of the angle iron 9 is provided with a through bolt mounting hole 92. The two angle irons 9 are respectively fixed to the ground and the top surface of the building space by expansion bolts 101 passing through the expansion bolt mounting hole 91; the strip partition wall 1 is fixedly connected to the two angle irons 9 by through bolts 102 passing through the through bolt mounting hole 92 and the through fixing hole 15. The two ends of the through bolts 102 are respectively located in the bolt mounting groove 14 and the second transverse groove 13. One side of the angle iron 9 is located in the first transverse groove 12, and the other side of the angle iron 9 is located in the second transverse groove 13.

[0046] Among them, angle iron 9 refers to a long strip of steel with two sides perpendicular to each other, forming an angle. For example... Figure 6 As shown, one side of the angle iron 9 is provided with at least one expansion bolt mounting hole 91, for example, the number of expansion bolt mounting holes 91 on one side of the angle iron 9 is 2. The other side is provided with at least one through bolt mounting hole 92, for example, the number of through bolt mounting holes 92 on the other side of the angle iron 9 is 3.

[0047] In addition, combined Figures 3 to 5 When installing the panel partition 1, align the angle iron 9 fixed to the ground with the angle iron 9 fixed to the top surface, and then place the panel partition 1 against it. This will quickly determine the installation position of the panel partition 1, so that the panel partition 1 can be quickly fixed to the angle iron 9 using the through bolt 102.

[0048] It is worth mentioning that, combined with Figure 8 In this case, since the groove sidewall 22 of the wall top finishing piece 2 has a certain thickness, if the wall top finishing piece 2 is directly fixed to the strip partition wall 1, the strip partition wall 1 will be uneven at the position of the wall top finishing piece 2. Therefore, in order to ensure that the strip partition wall 1 is flat on both sides in the thickness direction, the wall top finishing piece 2 is preferably embedded in the strip partition wall 1.

[0049] In practical applications, the specific implementation method for fixing the top wall trim 2 to the strip partition wall 1 is not unique.

[0050] For example, in one embodiment, combined with Figure 3 and Figure 4 For example, the integrated prefabricated wall panel also includes: a top mounting block 103; correspondingly, the panel partition 1 is also provided with a third transverse groove 16 on the other side of the thickness direction near the top surface, and the panel partition 1 is provided with top mounting holes 17 on both sides of the thickness direction near the top surface, and the top mounting block 103 is set in the top mounting hole 17. The higher groove sidewall 22 in the wall top closing part 2 is fixed to the top mounting block by fixing screws.

[0051] Among them, combined Figure 8 For example, the other side of the angle iron is provided with a through hole 93 corresponding to the position of the top mounting hole 17. When the top wall end piece 2 is installed, the top mounting block 103 is inserted into the top mounting hole 17 through the through hole 93.

[0052] Specifically, in combination Figure 4 In general, the positions of the top mounting hole 17 and the third transverse groove 16 can coincide, that is, the top mounting hole 17 can be formed on the bottom surface of the third transverse groove 16. In addition, the top mounting block 103 and the top mounting hole 17 can be connected by interference fit, snap-fit ​​or glue, and this application does not limit this.

[0053] Combination Figure 3 and Figure 4 When installing the top wall trim 2, insert the top mounting block 103 into the top mounting hole 17, and then fix the top wall trim 2 onto the top mounting block 103 with fixing screws. By designing the height of the top mounting block 103, the groove side wall 22 of the slot 21 of the top wall trim 2 is embedded in the third horizontal groove 16, ensuring that the inner side of the groove side wall 22 is flush with the plane of the strip partition wall 1.

[0054] Specifically, the wall panel 3 is preferably an inorganic wall panel, that is, the wall panel 3 is made of inorganic materials. In this embodiment, the thickness of the wall panel 3 is less than or equal to 1 cm, for example, the wall panel 3 is preferably 0.9 cm.

[0055] It is worth mentioning that, due to the brittleness and thinness of the inorganic wall panel, the inner wall of the wall panel connection hole 31 cannot be directly rigidly connected to the connector 7. This could easily cause the inner wall of the wall panel connection hole 31 to crack, causing the connector 7 to detach from the wall panel 3. To avoid this problem, in this embodiment, an expansion bolt 8 is used as an intermediate buffer. On the one hand, the internal thread 81 is used to rigidly connect with the screw 71 of the connector 7. On the other hand, the outer wall of the hollow cylinder is used to flexibly connect with the inner wall of the wall panel connection hole 31. That is, when the screw 71 is connected with the internal thread 81, the expansion bolt 8 is pushed outward, causing the outer wall of the hollow cylinder to expand outward, thereby increasing the friction force between the outer wall of the hollow cylinder and the inner wall of the wall panel connection hole 31, and firmly fixing the connector 7 to the wall panel 3.

[0056] Preferably, at least one of the inner wall of the wall panel connection hole 31 and the outer wall of the hollow cylinder where the expansion bolt 8 is located is a rough surface.

[0057] For example, combining Figure 10 For example, the rough surface includes the external thread 83 on the outer wall of the hollow cylinder. When installing and connecting, first insert the expansion bolt 8 into the wall plate connection hole 31, and then use the screw 71 of the connector 7 to connect with the internal thread 81, and squeeze the expansion bolt 8 outward so that the external thread 83 on the outer wall of the hollow cylinder abuts against the inner wall of the wall plate connection hole 31, so as to increase the friction between the external thread 83 and the inner wall of the wall plate connection hole 31, and securely fix the connector 7 to the wall plate 3.

[0058] For example, the rough surface includes multiple raised points disposed on the outer wall of the hollow cylinder, with the raised points spaced apart circumferentially along the outer wall of the hollow cylinder. Alternatively, the rough surface includes a grid disposed on the outer wall of the hollow cylinder. Specifically, similar to the working principle of the external thread 83, both the raised points and the grid can increase the frictional force between the outer wall of the hollow cylinder and the inner wall of the wall plate connecting hole 31. Of course, the rough surface is not limited to the aforementioned external thread 83, raised points, and grid; this application does not limit the specific structure of the rough surface.

[0059] Furthermore, in one embodiment, combined with Figure 10 In addition, the expansion bolt 8 is provided with at least one expansion joint 82, which axially penetrates the inner wall and outer wall of the hollow cylinder and has an opening at one end of the hollow cylinder in the axial direction.

[0060] Preferably, such as Figure 10 As shown, there are two expansion joints 82, which are positioned opposite each other on the outer wall of the hollow cylinder. The expansion joints 82 allow the expansion bolts 8 to expand and contract radially. When the expansion bolts 8 are inserted into the wall panel connection hole 31, they can be squeezed inward, causing the outer wall of the hollow cylinder to shrink inward, so that the expansion bolts 8 can be easily placed into the wall panel connection hole 31. When the screw 71 of the connector 7 is connected to the internal thread 81 of the expansion bolts 8, the expansion bolts 8 are squeezed outward, causing the outer wall of the hollow cylinder to expand outward, thereby increasing the friction between the outer wall of the hollow cylinder and the inner wall of the wall panel connection hole 31, and firmly fixing the connector 7 to the wall panel 3.

[0061] It is worth mentioning that the expansion bolt 8 can be a metal expansion bolt or a non-metal expansion bolt. In this embodiment, the expansion bolt 8 is preferably a non-metal expansion bolt, for example, a plastic expansion bolt. Using a plastic expansion bolt can reduce the weight of the wall panel 3 after it is connected to the connector 7, so that the wall panel 3 can be installed on the partition wall more easily.

[0062] Specifically, such as Figure 9 As shown, the wall panel connection hole 31 is preferably a round hole, and there are multiple wall panel connection holes 31 arranged in an array on the wall panel 3. It is understood that the inner diameter of the wall panel connection hole 31 is less than or equal to the outer diameter of the hollow cylinder where the expansion bolt 8 is located, so that the expansion bolt 8 can be inserted into the wall panel connection hole 31.

[0063] In one embodiment, combined Figure 10 For example, the connecting rod 72 is also connected to barbs 73. The barbs 73 include at least one set, and each set of barbs 73 has multiple barbs 73. The at least one set of barbs 73 is spaced apart circumferentially along the connecting rod 72, and each set of barbs 73 is spaced apart axially along the connecting rod 72.

[0064] For example, such as Figure 10 As shown, the connecting rod 72 is connected to 12 barbs 73. The 12 barbs 73 are divided into two groups, each group containing 6 barbs 73. The two groups of barbs 73 are arranged opposite to each other on the outer wall of the connecting rod 72, and the 6 barbs 73 in each group are spaced apart along the axial direction of the connecting rod 72.

[0065] The barbs 73 on the connecting rod 72 increase the contact surface with the structural adhesive within the wall panel mounting hole 11, thereby more firmly connecting the connecting rod 72 within the wall panel mounting hole 11 and preventing the connecting rod 72 from detaching from the structural adhesive.

[0066] In one embodiment, combined Figure 10 For example, connector 7 also includes a knob 74, which is connected to the other end of connector 72. By adding knob 74 to connector 72, screw 71 of connector 7 can be easily screwed into internal thread 81 of expansion bolt 8. Especially when connector 72 is connected to barb 73, knob 74 can provide a rotation position for screw 71 so that screw 71 can be easily screwed into internal thread 81 of expansion bolt 8.

[0067] In one embodiment, combined Figure 10 For example, the connector 7 also includes a limiting piece 75, which is disposed on the screw 71 or at the connection between the screw 71 and the connecting rod 72.

[0068] The limiting piece 75 is preferably nut-shaped. Specifically, the diameter of the limiting piece 75 is larger than the diameter of the hollow cylinder containing the expansion bolt 8, and the limiting piece 75 has an opening or threaded hole at its center. This opening or threaded hole mates with the screw 71 of the connector 7, allowing the limiting piece 75 to be screwed into the screw 71 using a wrench, thus connecting the limiting piece 75 to the screw 71. When the connector 7 is connected to the expansion bolt 8, the end of the hollow cylinder containing the expansion bolt 8 near the screw 71 abuts against the limiting piece 75, limiting the length by which the screw 71 is screwed into the expansion bolt 8. Therefore, the limiting piece 75 provided in this embodiment can prevent the screw 71 from being screwed into the expansion bolt 8 too much and breaking through the finish of the wall panel 3, thus protecting the wall panel 3.

[0069] It is worth mentioning that the sound-absorbing pad 4 can be attached to a plane on one side of the thickness direction of the partition wall 1, or it can be attached to the wall panel 3. Alternatively, the sound-absorbing pad 4 can be an independent structure, and when the wall panel 3 is connected to the partition wall 1, the sound-absorbing pad 4 is pressed between the wall panel 3 and the partition wall 1. In this embodiment, the sound-absorbing pad 4 is preferably attached to the back of the decorative surface of the wall panel 3.

[0070] Specifically, the sound-absorbing pad 4 can be made of various soft materials, including but not limited to rubber pads, foam pads, and sound-absorbing cotton. The sound-absorbing pad can isolate the wall panel 3 from the partition wall 1, preventing them from directly contacting each other and causing abnormal noise. Especially when the wall panel 3 and the partition wall 1 are compressed or there is a gap, it can also prevent the wall panel 3 from becoming hollow.

[0071] In one embodiment, see Figure 11 and Figure 12The baseboard fastener 5 includes a limiting groove 51, and the baseboard 6 includes a hook 61. The hook 61 is detachably engaged with the groove 51. When the hook 61 is connected to the groove 51, the baseboard 6 is fixedly connected to the baseboard fastener 5. It is understood that the connection method between the baseboard fastener 5 and the baseboard 6 is not limited to the above structure, and can also be implemented with other snap-fit ​​structures. This application does not limit this.
