Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a decorative surface for modular walls. Background Technology

[0002] In the process of modern industrialized construction, prefabricated buildings, with their significant advantages of high efficiency, environmental protection, and controllable quality, have gradually become the mainstream development direction of the construction industry. These buildings utilize prefabricated components manufactured in factories, with multiple concrete modules rapidly assembled on-site to form a prefabricated building. This significantly shortens the construction cycle but also places higher demands on the precise connection between each stage. The concrete module includes a hexagonal module top slab, module wall panels, and module bottom slab. The decorative surface is the interior finish of the concrete module, comprising an upper decorative layer and a lower skirting board. As a key decorative component transitioning between the wall and the floor, the skirting board not only fulfills the practical functions of concealing gaps and protecting the base of the wall but also directly affects the overall aesthetics of the interior space and the integrity of the industrialized decoration. However, the on-site installation environment for prefabricated buildings is complex, and deviations in the construction precision of the floor and walls often result in diverse gap sizes, posing a significant challenge to the adaptability of the skirting board.

[0003] In existing technologies, skirting boards mostly adopt a rigid structure with fixed dimensions, relying on expansion screws, nails, or glue for rigid connection to the wall during installation. This approach reveals significant limitations when dealing with gaps of varying heights: Firstly, if the gap height does not match the pre-set size of the skirting board, secondary processing such as on-site cutting and grinding is required, which not only consumes a lot of labor costs but also easily damages the integrity of the component due to operational errors, affecting the decorative effect. Secondly, rigid fixing methods cannot absorb the stress generated by slight settlement or temperature deformation of the wall and floor, and after long-term use, loosening, warping, or even falling off are likely to occur, reducing structural stability and increasing later maintenance costs. In addition, traditional installation processes require a high level of operator skill, and differences in the skills of different installers may lead to inconsistent fit between the skirting board and the wall or floor, making it difficult to achieve the standardized and uniform effect required for industrialized decoration, which seriously restricts the improvement of the overall construction efficiency of prefabricated buildings.

[0004] Therefore, there is an urgent need for a decorative surface for modular walls that can adaptively adjust according to the gap between the module base plate and the module wall during installation. Utility Model Content

[0035] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," "left," "right," "front," and "rear" are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference. Among them, "up" refers to the direction away from the module base plate 3, "down" refers to the direction close to the module base plate 4, "front" refers to the direction away from the module wall 3, "back" refers to the direction close to the module wall 3, and "left" and "right" refer to the directions perpendicular to the plane containing the front-back direction and the up-down direction, that is, the length direction of the module wall 3.

[0036] Example 1:

[0037] Reference Figures 1 to 5 This embodiment proposes a decorative surface for modular walls. When decorating the outer surface of the modular wall 3, the skirting board 2 can adaptively adjust its height to always abut against the module base plate 4. Furthermore, by pre-fixing the decorative layer 1 and back panel 21 to the modular wall 3 during prefabrication in the prefabrication factory, on-site procedures are reduced, saving time. Specifically, the decorative surface for modular walls in this embodiment includes a decorative layer 1 and a skirting board 2 fixedly connected to the outer surface of the modular wall 3. The skirting board 2 includes a back panel 21 and a decorative panel 22, as detailed below.

[0038] For prefabricated buildings, multiple modular wall panels 3 and modular base plates 4 are typically manufactured in a prefabrication factory. However, some processes on the modular base plate 4 are not yet completed and require on-site finishing. Therefore, it's impossible to install the skirting board 2 in the prefabrication factory. Furthermore, on-site finishing processes can lead to unevenness on the surface of the prefabricated modular base plate 4, preventing a perfectly flat finish. Since conventional skirting boards 2 cannot be adjusted, gaps form between them and the prefabricated modular base plate 4, easily accumulating dust, hair, and other debris, making cleaning difficult and fostering bacterial growth. In humid environments, moisture can seep into these gaps, causing mold growth on the floor or wall base, especially in areas like bathrooms and kitchens, potentially leading to structural damage. Small foreign objects (such as small parts or insects) may fall into the gaps and be difficult to remove, affecting the cleanliness of the space. Furthermore, gaps disrupt the overall continuity between the skirting board 2 and the prefabricated modular base plate 4, creating a visually disjointed feel. This is especially noticeable in high-end interior design, highlighting insufficient construction precision and reducing the overall sophistication of the space. Uneven gap widths can further amplify installation flaws, affecting the overall harmony of the architectural decoration. Therefore, the skirting board 2 needs to be adjustable to accommodate the gaps between the modular base plate 4 and the modular wall 3.

[0039] In this embodiment, the back plate 21 includes a horizontal plate 211 and a vertical plate 212 connected to each other in a T-shape. The vertical plate 212 is attached to the lower part of the module wall 3. The decorative layer 1 is fixed to the module wall 3 and its lower side abuts against the horizontal plate 211. A vertical front side plate 213 is fixedly provided below the middle of the horizontal plate 211. At least one first positioning member 23 is connected to the front side plate 213. The first positioning member 23 can move along the front-back direction on the front side plate 213 and is limited to its front and rear ends. The decorative plate 22 is placed on the module bottom plate 4. When the front end of the first positioning member 23 is fixed to the front side of the front side plate 213, the rear end of the first positioning member 23 pushes the decorative plate 22 to abut against the vertical plate 212.

[0040] Specifically, refer to Figure 1 The back panel 21 includes an integrally formed T-shaped horizontal panel 211 and a vertical panel 212. During the prefabrication of the modular wall 3 in the prefabrication plant, the horizontal panel 211 and vertical panel 212 are pre-fixed to the lower end of the modular wall 3. The back panel 21 is fixed to the modular wall 3 by screwing, pre-embedding, or integral molding. The vertical panel 212 is rectangular with its long side extending horizontally and its wide side extending vertically. The horizontal panel 211 is rectangular with its long side extending horizontally and its wide side extending forward and backward. The subsequent decorative layer 1 is fixed to the modular wall 3 by adhesive, screwing, or snap-fitting, with its bottom surface abutting against the upper surface of the horizontal panel 211. A rectangular front side plate 213 is connected to the lower middle part of the horizontal plate 211 by welding, integral molding, or screwing. The front side plate 213 extends horizontally in length and vertically in width. At least one first positioning member 23 is connected to the front side plate 213. Thus, the first positioning member 23 can move along the front-back direction on the front side plate 213 and is limited to its front and rear ends. Specifically, the limitation of the first positioning member 23 is that the height of the protruding edges at both ends of the first positioning member 23 is greater than the height of the hole through which the first positioning member 23 is connected to the front side plate 213. The decorative plate 22 is placed on the module base plate 4. When the front end of the first positioning member 23 is fixed to the front side of the front side plate 213 by welding, bonding, or screwing, the rear end of the first positioning member 23 moves backward until it abuts against the decorative plate 22 and pushes the decorative plate 22 backward until the decorative plate 22 abuts against the vertical plate 212.

[0041] Furthermore, when the first positioning member 23 is multi-layered, the multi-layered first positioning members 23 are disposed on the front side plate 213 and spaced apart along the lower direction of the front side plate 213. The decorative plate 22 is placed on the module base plate 4. The upper end of the decorative plate 22 is attached to the vertical plate 212 and located in the front-rear direction plane space of the front side plate 213. Thus, the part of the upper end of the decorative plate 22 that extends into the front-rear direction plane space of the front side plate 213 abuts against several first positioning members 23, thereby pushing the decorative plate 22 to move backward and abut against the vertical plate 212.

[0042] When the first positioning member 23 is a single layer, the single-layer first positioning member 23 is set at the lower part of the front side plate 213. Thus, the decorative panel 22 is placed on the module base plate 4. The upper end of the decorative panel 22 is in contact with the vertical plate 212 and is located in the planar space in the front-rear direction of the front side plate 213. Thus, the decorative panel 22 is pushed by the single-layer first positioning member 23 to abut against the vertical plate 213. Compared with the multi-layer first positioning member 23, it can save materials and installation time.

[0043] In summary, compared with the existing technology, the decorative panel 22 is installed on the back panel 21. Under the action of gravity, the lower end of the decorative panel 22 abuts against the module base plate 4. The first positioning member 23 can fix the decorative panel 22 to the vertical plate 212. The skirting board 2 has a simple overall structure and a neat appearance. Moreover, the skirting board 2 abuts against the decorative layer 1 to form an integral whole, which is conducive to improving the aesthetics of the module wall panel.

[0044] Furthermore, a second positioning member 24 is connected to the front side panel 213 above the first positioning member 23. The second positioning member 24 is movable in the front-rear direction on the front side panel 213 and is limited to its front and rear ends. When the front end of the second positioning member 24 is fixed to the front side panel 213, the second positioning member 24 is above the decorative panel 22 to form an upward limit on it.

[0045] Specifically, refer to Figure 1 The first positioning member 23 is located at the lower part of the front side panel 213, and the second positioning member 24 is located at the upper part of the front side panel 213. Similarly, the shape of the second positioning member 24 and the first positioning member 23 are such that they can move along the front-rear direction on the front side panel 213, and the second positioning member 24 is limited at its front and rear ends. Specifically, the limitation of the second positioning member 24 is achieved by the height of the protruding edges at both ends of the second positioning member 24 being greater than the height of the hole through which the second positioning member 24 passes in the front side panel 213. Thus, when the front end of the second positioning member 24 is fixed to the front side panel 213 by welding, bonding, or screwing, the rear end of the second positioning member 24 moves rearward to above the decorative panel 22, thus limiting the upward movement of the decorative panel 22.

[0046] Furthermore, a strip-shaped positioning hole 2131 extending in the left-right direction is provided on the front side plate 213 corresponding to the first positioning member 23 and the second positioning member 24. Each layer of the first positioning member 23 and the second positioning member 24 corresponds to one strip-shaped positioning hole 2131. The first positioning member 23 and the second positioning member 24 are strip-shaped positioning members extending in the left-right direction, and the cross-sections of the first positioning member 23 and the second positioning member 24 are both H-shaped, h-shaped or n-shaped.

[0047] Specifically, refer to Figure 2 and Figure 4The front panel 213 has positioning holes 2131 extending along the left-right direction in the vertical direction. The positioning holes 2131 are strip-shaped, with one layer of first positioning member 23 and one layer of second positioning member 24 corresponding to one positioning hole 2131. Thus, the first positioning member 23 and the second positioning member 24 can move in the front-back direction of the positioning holes 2131. Since the first positioning member 23 and the second positioning member 24 are strip-shaped positioning members extending in the left-right direction, they are distributed along the entire length of the positioning holes 2131. The height of the positioning holes 2131 is in the range of 2mm-2.5mm, while the thickness of the middle part of the first positioning member 23 and the second positioning member 24 is 1mm. Therefore, the distance that the first positioning member 23 and the second positioning member 24 can move in the vertical direction is in the range of 1mm-1.5mm. Furthermore, referring to… Figures 6 to 8 The cross-sectional shape of the first positioning member 23 and the second positioning member 24 is H-shaped, h-shaped or n-shaped. Thus, the first positioning member 23 and the second positioning member 24 can move in the front-back direction on the positioning hole 2131. The H-shaped, h-shaped or n-shaped protrusions at both ends of the first positioning member 23 and the second positioning member 24 are used to lock the positioning hole 2131, thereby achieving the limitation of the two ends of the first positioning member 23 and the second positioning member 24.

[0048] Furthermore, the upper end of the decorative panel 22 is provided with a forward-extending limiting part 221. When the front end of the first positioning member 23 is fixed to the front side of the front panel 213, the limiting part 221 is located above at least one layer of the first positioning member 23.

[0049] Specifically, refer to Figure 1 The decorative panel 22 itself is relatively thin, while the limiting part 221 is 1mm thick, and the length of the limiting part 221 in the front-to-back direction is within the range of 2mm-3mm. Therefore, when the decorative panel 22 is placed on the module base plate 4, the limiting part 221 can be prevented from tipping over by the first positioning member 23. The limiting part 221 is located between the horizontal plate 211 and the end plate 214, and the first positioning member 23 is also located between the horizontal plate 211 and the end plate 214. In order to limit the tipping of the decorative panel 22 in the front-to-back direction, the limiting part 221 is located above at least one layer of the first positioning member 23.

[0050] Furthermore, the rear side of the decorative panel 22 is a vertical plane, the lower end of the decorative panel 22 forms a base 222 sitting on the module base plate 4, and the center of gravity of the decorative panel 22 is located at its lower part. The front side of the base 222 is provided with an arc-shaped surface extending from its upper part forward in an arc shape.

[0051] Specifically, refer to Figure 1In the cross-sectional view of the skirting board 2 in the left-right direction, the lower end face of the decorative panel 22 extends in the left-right direction, while the rear side of the decorative panel 22 extends in the up-down direction. The lower end of the decorative panel 22 forms a base 222 sitting on the module base plate 4. The lower part of the base 222 is larger than the upper part of the base 222, and the base 222 has a larger volume, therefore, the base 222 is heavier. As a result, the center of gravity of the decorative panel 22 is biased downward. Therefore, the decorative panel 22 is more likely to stand under the back plate 21 when it abuts against the vertical plate 212, and the decorative panel 22 will not tip over when the first positioning member 23 and the second positioning member 24 are moved subsequently.

[0052] Moreover, refer to Figure 1 The front side of the base 222 is an arc-shaped surface. The arc-shaped surface extends forward and downward from the upper part of the base 222 to form the front side of the base 222. The arc-shaped surface can not only direct the water on the front side of the decorative panel 22 forward, but also prevent water from seeping into the baseboard 2, thereby preventing the baseboard 2 from becoming moldy and emitting odors.

[0053] Furthermore, the lower end of the front panel 213 is also fixedly connected to an end plate 214 extending in the left-right direction. The end plate 214 is parallel to the horizontal plate 211, and the end plate 214 and the horizontal plate 211 are respectively provided with slots 215 on opposite sides. The back panel 21 also includes a locking strip 216 extending in the left-right direction. The locking strip 216 can be detachably locked into the two slots 215. When the locking strip 216 is locked into the slots 215, the locking strip 216 pushes the first positioning member 23 and the second positioning member 24. Then the first positioning member 23 pushes the decorative panel 22 to abut against the vertical plate 212, and the second positioning member 24 is above the decorative panel 22 to limit its upward movement.

[0054] Specifically, the lower end of the front side plate 213 is fixedly connected to the end plate 214 by welding, screwing, or integral molding. The end plate 214 extends in the front-back and left-right directions and is cuboid. The long side of the end plate 214 extends along the length of the front side plate 213, and the wide side of the end plate 214 extends in the left-right direction. The end plate 214 and the horizontal plate 211 are opposite and parallel. The opposite sides of the end plate 214 and the horizontal plate 211 are provided with a latch 215. The latch 215 can be strip-shaped and extended along the horizontal plate 211 and the end plate 214, or it can be multiple dispersed protrusions distributed along the opposite sides of the horizontal plate 211 and the end plate 214. The latch 215 is located in front of the front side plate 213. The clip 216 can be detachably inserted into the two slots 215. When the clip 216 is inserted into the slots 215, the clip 216 is parallel to the front side plate 213. The clip 216 abuts against the front end face of the first positioning member 23 and the second positioning member 24. The front side plate 213 abuts against the rear front side face of the first positioning member 23 and the second positioning member 24. Thus, the clip 216 pushes the first positioning member 23 and the second positioning member 24 to move backward. The first positioning member 23 moves backward so that its rear end abuts against the vertical plate 212. The rear side face of the clip 216 abuts against the front end face of the first positioning member 23, thereby fixing the first positioning member 23. The second positioning member 24 moves backward until it reaches above the decorative panel 22 to limit its upward movement.

[0055] Furthermore, the distance between the horizontal plate 211 and the end plate 214 is within the range of 22mm-25mm.

[0056] Specifically, refer to Figure 1 The distance between the horizontal plate 211 and the end plate 214 is the adjustment range of the decorative plate 22. Thus, the height adjustment value of the decorative plate 22 is within the range of 22mm-25mm.

[0057] Furthermore, the retaining strip 216 is rectangular, and its long side extends along the entire length of the horizontal plate 211. The rectangular retaining strip 216 can cover the front ends of the first positioning member 23 and the second positioning member 24. When the retaining strip 216 is inserted into the retaining slot 215, the long side of the retaining strip 216 is the same length as the horizontal plate 211, and the retaining strip 216 can cover the space between the horizontal plate 211 and the end plate 214. As a result, the appearance of the skirting board 2 is neater and more aesthetically pleasing.

[0058] Furthermore, the back plate 21 is fixed to the module wall 3 by multiple bolts. The vertical plate 212 has multiple threaded holes evenly spaced along the left and right direction on its upper part, and the bolts pass through the threaded holes to fix the vertical plate 212 to the module wall 3.

[0059] Furthermore, the distance between the horizontal plate 211 and the decorative plate 22 in the vertical direction is within the range of 2mm-20mm, and the error between the height of the upper surface of the module base plate 4 and the standard height of the upper surface of the module base plate 4 is within the range of -10mm-10mm.

[0060] Specifically, refer to Figure 2 and Figure 4 In subsequent processes, the height error of the module base plate 4 is within the range of -10mm to 10mm. Therefore, it is necessary to adjust the decorative panel 22 so that the decorative panel 22 and the module base plate 4 can abut together. The vertical distance between the horizontal plate 211 and the decorative panel 22 is within the range of 0mm to 20mm. When the height of the module base plate 4 is without error, the distance between the upper end of the decorative panel 22 and the horizontal plate 211 is 10mm. Moreover, the height adjustment value of the decorative panel 22 is within the range of 22mm to 25mm. Therefore, when the height value of the upper surface of the module base plate 4 is within the range of -10mm to 10mm, the decorative panel 22 and the module base plate 4 can abut together.

[0061] In addition, the thickness of the back plate 21 is in the range of 1mm-2mm, the length of the horizontal plate 211 in the front-to-back direction is in the range of 9mm-12mm, and the length of the first positioning member 23 and the second positioning member 24 in the front-to-back direction is in the range of 3mm-5mm.

[0062] Example 2:

[0063] Reference Figure 9 This embodiment proposes an installation method for the decorative surface of a modular wall, which is detailed below.

[0064] In this embodiment, the prefabrication plant mass-produces concrete modules. First, the back plate 21 is pressed against the module wall 3 where the skirting board 2 needs to be installed. Expansion screws are driven into the wall through the threaded holes. The rear ends of the first positioning member 23 and the second positioning member 24 are pressed against the front side plate 213. Then, the outer surface of the module wall 3 is decorated to form the decorative layer 1 of the module wall 3. At this time, there are still some processes that have not been completed on the module base plate 4.
