[0002] In prefabricated buildings, a five-sided structure without a ground surface is assembled with a ground structure to form a rectangular building module.

[0003] In the on-site assembly of the above building modules, the actual height difference between the ground and the wall is uncertain. Therefore, the skirting boards within the building modules are usually not prefabricated in the factory and need to be assembled on-site, and then installed on-site after the floor finish is completed. This increases the amount of on-site work and extends the on-site construction time. Utility Model Content

Detailed Implementation

[0027] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0028] Example 1:

[0029] Reference Figures 1 to 3 This embodiment provides an adjustable skirting board for prefabricated buildings, including a fixing member 1, a connecting member 2, a cover plate 4, and at least one transmission assembly 3. The fixing member 1 is a groove structure with an opening, prefabricated onto the wall with the opening facing downwards. The fixing member 1 serves to fix the skirting board, and its opening is used to install the connecting member 2, the cover plate 4, and the transmission assembly 3. The connecting member 2 is connected to the back of the cover plate 4 through the transmission assembly 3. All three can enter and exit the fixing member 1 through the opening, allowing them to be in an installed state and a disassembled state.

[0030] In the installed state, the connector 2 is detachably connected to the fixing member 1, the lower edge of the cover plate 4 extends out from the fixing member 1, and the transmission component 3 can drive the cover plate 4 to move up and down to adjust the length of the exposed area of ​​the cover plate 4 extending out of the fixing member 1. The exposed area of ​​the cover plate 4 is used to cover the gap between the wall and the ground.

[0031] In this way, skirting board components can be prefabricated on the precast wall surface. After the precast wall and precast floor are assembled on site, the height of the cover plate can be adjusted on-site to cover the gaps of different sizes formed after the precast wall and precast floor are assembled. This prefabrication of skirting board components on the precast wall surface eliminates the need for on-site installation and improves the on-site construction efficiency of prefabricated buildings.

[0032] Reference Figures 1 to 3This embodiment provides an adjustable skirting board for prefabricated buildings. The transmission assembly 3 includes two racks 31 and two gears 32. The two racks 31 extend along the extension direction of the cover plate 4 and are disposed on the side of the cover plate 4 facing the connector 2, with the tooth grooves of the two racks 31 facing each other. The two gears 32 are rotatably disposed on the side of the connector 2 facing the cover plate 4, and the two gears 32 are meshed. The two gears 32 are disposed between the two racks 31, and the two gears 32 mesh with the two racks 31 one-to-one. A certain preload is provided between the racks 31 and the gears 32 to prevent the racks 31 from moving slightly along the axial direction of the gears 32.

[0033] One of the two gears 32 is the driving gear, and the other is the driven gear. The driving gear has a connecting portion on the side facing the cover plate 4, and the area corresponding to the connecting portion of the cover plate 4 has a strip-shaped through hole 41 extending in the extending direction of the cover plate 4. The skirting board component also includes an adjusting member 5, which passes through the strip-shaped through hole 41 from the outside of the cover plate 4 and is detachably connected to the connecting portion. Twisting the adjusting member 5 drives the driving gear to rotate, and the driving gear and the driven gear rotate in opposite directions to drive the two racks 31 to rise and fall synchronously, thereby driving the cover plate 4 to rise and fall.

[0034] When the cover plate 4 is raised or lowered, the strip-shaped through hole 41 moves relative to the adjusting member 5, and the strip-shaped through hole 41 limits the longest and shortest extension length of the cover plate 4. The vertical length of the strip-shaped hole is 0.1-1.5cm, that is, the range of raising and lowering the cover plate 4 is 0.5-1.5cm.

[0035] Reference Figures 1 to 5 This embodiment provides an adjustable skirting board for prefabricated buildings, including a locking member 6. The connecting part is a square hole 321 located on the side of the drive wheel facing the cover plate 4, and the square hole 321 is located on the central axis of the drive wheel. The locking member 6 can be inserted into both the strip-shaped through hole 41 and the square hole 321 from the outside of the cover plate 4, and the strip-shaped through hole 41 and the square hole 321 can simultaneously restrict the rotation of the locking member 6 to maintain the height of the cover plate 4 adjusted by the adjusting member 5 from the ground. One end of the locking member 6 inserted into the square hole 321 is a square rod, and the locking member 6 cannot rotate relative to the square hole 321. The other end of the locking member 6 extends out from the strip-shaped through hole 41, and the end of the locking member 6 located in the strip-shaped through hole 41 can be locked in the strip-shaped through hole 41 and does not rotate; for example, refer to Figure 1 The locking element 6 is a rod with a rectangular cross-section, and the cross-section of the strip-shaped through hole 41 is also rectangular. The locking element 6 is adapted to the strip-shaped through hole 41, and the two sides of the rod are attached to the inner wall of the strip-shaped through hole 41. Therefore, the rod cannot rotate on its own. In this way, the rod restricts the rotation of the drive wheel to maintain the current height of the cover plate 4.

[0036] It should be noted that the locking state of the locking component 6 on the cover plate 4 can be such that, before the baseboard installation is completed, the cover plate 4 is first raised using the adjusting component 5, meaning the cover plate 4 is suspended relative to the ground, and then locked. This way, the cover plate 4 does not interfere with the construction of the ground area. After the ground area construction is completed, the locking component 6 is removed, and the height of the cover plate 4 from the ground is adjusted again using the adjusting component 5 so that the cover plate 4 falls to the ground. Furthermore, after the plate 4 falls to the ground, the locking component 6 is used again to lock the cover plate 4 to ensure its stability after the baseboard installation. The length of the locking component 6 after installation should not be too long; after inserting the locking component 6 into the strip-shaped through hole 41, the end of the locking component 6 should protrude from the cover plate 4 by approximately 2mm.

[0037] Reference Figures 1 to 5 This embodiment provides an adjustable skirting board for prefabricated buildings. The connector 2 has two male grooves 21 extending parallel to the ground on the side opposite to the gear 32, spaced apart along the extension direction of the cover plate 4. The inner side of the fixing member 1 has two female grooves 11 extending parallel to the ground, corresponding to the positions of the two male grooves 21, spaced apart along the extension direction of the cover plate 4. The two male grooves 21 can be detachably engaged with the two female grooves 11 to detachably install the connector 2 onto the fixing member 1.

[0038] The distance between the two male grooves 21 is less than the distance between the two female grooves 11. During installation, the connector 2 is inserted into the opening of the fixing part 1 at a slightly inclined position. First, the male groove 21 and female groove 11 away from the ground are fastened together. Then, the connector 2 is adjusted to a vertical position and lifted upwards to complete the fastening of the male groove 21 and female groove 11 near the ground. Alternatively, if the installation site space allows, the connector 2 (with the cover plate 4 installed) can be inserted from one end of the fixing part 1. In this installation method, the male groove 21 can be slid along the female groove 11 to complete the installation, which is suitable for situations where the skirting board is relatively short.

[0039] Reference Figures 1 to 5This embodiment provides an adjustable skirting board for prefabricated buildings. The fixing member 1 includes a first plate 12, a second plate 13, and a third plate 14. Specifically, the first plate 12 and the second plate 13 are arranged opposite each other and are both parallel to the wall surface. The third plate 14 is arranged parallel to the ground between the first plate 12 and the second plate 13. The edge of the first plate 12 in the direction opposite to the extension of the cover plate 4 is higher than the third plate 14. The outer side of the second plate 13 is flush with the third plate 14. The upper part of the third plate 14 is used to accommodate the finishing layer of the wall surface, and the part of the first plate 12 that is higher than the third plate 14 is used to cover the gap between the finishing layer and the third plate 14. The part of the first plate 12 that is lower than the third plate 14 is used to cover the upper part of the cover plate 4, improving aesthetics. At the same time, the part of the first plate 12 that is lower than the third plate 14 can restrict the movement of the cover plate 4 away from the connecting member 2, ensuring that the transmission component 3 adjusts the lifting and lowering of the cover plate 4. Two female grooves 11 are provided inside the second plate 13.

[0040] Reference Figures 1 to 5 This embodiment provides an adjustable skirting board for prefabricated buildings. The upper part of the cover plate 4 is a vertical flat plate, which can slide vertically against the inner side of the first plate 12 for easy adjustment. The portion of the cover plate 4 extending out of the opening of the fixing member 1 is a flat plate or an arc-shaped curved plate extending away from the connecting member 2. When the portion of the cover plate 4 extending out of the opening of the fixing member 1 is an arc-shaped curved plate, it can reduce dust dead corners and facilitate cleaning of the skirting board.

[0041] Reference Figures 1 to 5 This embodiment provides an adjustable skirting board for prefabricated buildings. When the skirting board is long, multiple transmission components 3 need to be installed, spaced apart, with a distance of 1.5-3m between adjacent transmission components 3. When adjusting the height of the cover plate 4, multiple people can adjust different transmission components 3 simultaneously, or they can adjust different transmission components 3 sequentially, because the lifting range of the cover plate 4 is 0.1-1.5cm. When the distance between two adjacent transmission components 3 is large (1.5-3m), it does not affect the adjustment function of the two adjacent transmission components 3.

[0042] Finally, let me explain the assembly and adjustment process of the aforementioned skirting board: First, fix the fastener 1 to the prefabricated wall surface with studs, and then the upper ends of the third plate 14 and the first plate 12 are stuck to the wall surface finish layer; then the cover plate 4 and the connector 2 are connected by meshing of the rack 31 and the gear 32, and then the connector 2 is installed to the inside of the second plate 13 to complete the assembly.

[0043] During adjustment, insert the adjusting piece 5 into the strip-shaped through hole 41 and the square hole 321 on the drive wheel, and rotate the adjusting piece 5 to adjust the height of the cover plate 4 so that the lower edge of the cover plate 4 does not touch the precast ground. Then, pull out the adjusting piece 5 and insert the locking piece 6 into the strip-shaped through hole 41 and the square hole 321 on the drive wheel to fix the height of the cover plate 4. After the ground surface construction is completed, insert the adjusting piece 5 into the strip-shaped through hole 41 and the square hole 321 on the drive wheel, and rotate the adjusting piece 5 to adjust the height of the cover plate 4 so that the lower edge of the cover plate 4 touches the precast ground. Then, insert the locking piece 6 into the strip-shaped through hole 41 and the square hole 321 on the drive wheel to fix the height of the cover plate 4 again.
