Description

Technical Field

[0001] The invention belongs to the field of building decoration, and in particular relates to an assembling and installing process of a hyperbolic curved stone skirting. Background Art

[0002] As a functional component bridging the gap between walls and floors, skirting boards protect walls, cover gaps, and provide decorative space. The development of their materials and craftsmanship has always been closely tied to architectural aesthetics and practical needs. Traditional skirting boards are made of a variety of materials, including solid wood, ceramic tiles, metal, cement-based materials, and natural stone. They are primarily flat (right-angled) and molded (with decorative lines), and have long served classical and traditional decor styles. Solid wood skirting boards, with their natural grain, are suitable for upscale spaces, but require regular maintenance and have poor moisture resistance. Stone skirting boards are often used in high-traffic areas due to their wear and impact resistance, but they can be brittle and can cause color bleeding. Metal and cement-based materials also have their own drawbacks (such as metal easily scratches and cement-based construction takes a long time), making them difficult to meet diverse needs.

[0003] With the advancement of modern architectural technology and the upgrading of aesthetics, the inherent defects of traditional skirting boards have become increasingly prominent, becoming a bottleneck restricting the improvement of space quality:

[0004] In terms of functionality, the 90° right-angle design creates dead corners where dust accumulates, making cleaning difficult. The wood material is easily deformed by moisture, and the stone bottom is prone to mold, resulting in insufficient moisture resistance. The joints often crack due to the lack of expansion joints or aging of adhesives.

[0005] In terms of decoration, traditional carvings and moldings clash with modern minimalist styles. Furthermore, wood finishes tend to yellow and stone gloss fades, making them difficult to maintain long-term aesthetic appeal. Regarding construction and maintenance, low manual processing precision and rough wall surface treatment lead to uneven installation. Wet-stick fixing methods, for example, require entire sections to be replaced if damaged, resulting in high maintenance costs.

[0006] In addition, traditional materials have natural limitations. For example, the anisotropy of solid wood causes cracking and insect infestation, and the low bending strength of natural stone causes brittle fracture. In addition, traditional design concepts only focus on "covering gaps" and cannot adapt to the integrated needs of modern buildings such as hidden wires and smart sensors.

[0007] To this end, the present invention provides an assembly and installation process for a hyperbolic curved stone skirting board. Summary of the Invention

[0008] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0009] The technical solution adopted by the present invention to solve the technical problem is: the assembly and installation process of the hyperbolic curved stone skirting described in the present invention includes the following steps:

[0010] S1. Wall pretreatment: clean the wall dust and oil stains, check to ensure there are no hollows on the wall, and repair and level any uneven areas;

[0011] S2. Positioning reference setting: according to the design height, use the laser level to pop up the baseboard installation reference line;

[0012] S3. Installation and fixing: Choose any of the following fixing methods according to the curvature and weight of the skirting board:

[0013] If the wall surface is flat and the curvature of the skirting is small, use the gluing method: use epoxy resin glue or artificial stone special glue to apply dots on the back of the skirting, with the glue dots spaced 20-30cm apart. Attach the skirting to the wall reference line, tap and compact it, and then calibrate it with a laser level.

[0014] If the skirting is large-curved or heavy, the keel dry hanging method is used: or aluminum alloy brackets are used to form a metal keel, and pre-embedded hangers are fixed on the back of the light steel keel line according to the curvature of the wall at the skirting, and the hangers are inserted into the metal keel and reinforced with screws;

[0015] S4. Adjustment and joint treatment: Adjust the position of the skirting board after installation to ensure a tight fit, use caulking agent to repair the seams of the skirting board, and polish it to a smooth state.

[0016] Preferably, in step S1, the flatness error of the repaired wall surface is ≤2 mm.

[0017] Preferably, in the gluing method of step S3, during the pressing and adjusting process, a rubber hammer is used to tap the surface of the skirting board to achieve compaction.

[0018] Preferably, in the keel dry hanging method of step S3, the installation spacing of the metal keels is adapted to the spacing of the pre-embedded hangers on the back of the skirting board, and the spacing between the keel fixing points is ≤50 cm.

[0019] Preferably, when the skirting board is a segmented structure, before step S3, the segmented skirting board is spliced ​​by using mortise and tenon joints in combination with gluing, and the splicing parts are designed with bevel splicing or invisible snap fasteners.

[0020] Preferably, the length of a single section of the segmented skirting board is 5 to 10 cm.

[0021] Preferably, after the joint processing step of step S4, the method further includes reserving an expansion joint: reserving a gap of 1 to 2 mm at the corner between the skirting and the ground or wall.

[0022] Preferably, before step S1, a water and electricity pipeline avoidance confirmation step is also included: the position of the water and electricity pipelines in the wall is confirmed by a wall pipeline detector, and the avoidance area is marked.

[0023] Preferably, in the keel dry hanging method of step S3, the metal keel is fixed to the wall surface by using expansion screws, and the expansion screws are embedded in the wall to a depth of ≥5 cm.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The assembly and installation process for a hyperbolic curved stone skirting board described in this invention addresses the problem of traditional skirting boards being prone to dust accumulation and difficult to clean. The hyperbolic curved design eliminates 90° dead corners, and the curved transition prevents dust from accumulating. Combined with the caulking and polishing treatment at the joints during the process, the surface is smooth and groove-free, making it easy to clean without special tools. To address the defect of poor moisture resistance, the artificial stone (especially the quartz stone base) adapted for the process is inherently dense and non-porous. During installation, a 1-2mm expansion joint is reserved to prevent water accumulation at the bottom. At the same time, the keel dry hanging method maintains a slight gap between the skirting board and the wall, reducing capillary water absorption and solving the problem of wooden skirting boards expanding due to moisture and mold on the bottom of the stone. Regarding cracking at the joints, the process clearly reserves a 1-2mm expansion joint and uses a highly weather-resistant adhesive such as epoxy resin glue. Combined with the mortise and tenon joint and gluing method, this effectively offsets thermal expansion and contraction stresses, avoiding the potential cracking caused by aging of traditional white latex or the lack of expansion joints.

[0026] 2. The assembly and installation process of a hyperbolic curved stone skirting board described in the present invention has a curved design that retains the smoothness of the lines while getting rid of the monotony of the flat style and the complexity of the molding style. It can seamlessly adapt to a variety of styles such as modern simplicity, light luxury, and artistic minimalism. Especially in high-end commercial spaces and special-shaped curved surface design scenes, it can enhance the sense of spatial hierarchy through the change of curvature, and has more design tension than traditional right-angle shapes. To address the problem of color aging, artificial stone adopts a surface treatment technology with excellent UV resistance. The paint surface or original color layer is not easily affected by direct sunlight and turns yellow. In addition, the quartz stone-based material has a stronger tolerance to detergents, which avoids the loss of gloss of natural stone due to corrosion by acidic detergents and maintains a stable decorative effect for a long time.

[0027] 3. The assembly and installation process for the hyperbolic curved stone skirting described in this invention requires wall pretreatment to achieve a flatness error of ≤2mm. A laser level is used to calibrate the installation position throughout the entire process, and CNC engraving ensures the skirting's curvature and dimensional accuracy of ±0.2-0.3mm. This far exceeds the precision level of traditional manual processing, preventing hollowing and warping problems at the source. Regarding maintenance difficulties, the segmented skirting (single section 5-10cm) adopts a modular design, allowing for individual replacement of damaged parts without removing the entire section. The mortise and tenon joints and adhesive bonding facilitate disassembly, and the screw fixing structure of the dry-hanging keel method also supports partial loosening. Compared to traditional wet-installation methods (such as cement mortar installation), which require replacing entire sections, maintenance costs are significantly reduced.

[0028] 4. The assembly and installation process of the hyperbolic curved stone skirting board described in the present invention overcomes the problems of cracking, deformation and insect infestation of solid wood skirting boards. Artificial stone does not have the anisotropy caused by natural texture, has a stable moisture content and is added with anti-corrosion ingredients; it solves the brittle fracture and color bleeding defects of natural stone. The bending strength of artificial stone reaches 35~45MPa (natural marble is only 25MPa), and the surface density has been verified by experiments to be resistant to the penetration of dark liquids such as red wine; it avoids the obvious scratches and noise conduction problems of metal skirting boards. The surface hardness of artificial stone is high (especially quartz stone base) and has a certain toughness. It is not easy to leave marks with slight collisions. The cushioning design of the fit with the wall during installation reduces vibration and noise; it improves the cracking and falling defects on the surface of cement-based skirting boards. The shrinkage stress of artificial stone is small, and the moisture and heat deformation rate is only 0.05%~0.1%. Combined with the keel fixation, the connection stability with the base layer is enhanced. DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] An assembly and installation process of a hyperbolic curved stone skirting according to an embodiment of the present invention includes the following steps:

[0031] S1. Wall pretreatment: clean the wall dust and oil stains, check to ensure there are no hollows on the wall, and repair and level any uneven areas;

[0032] S2. Positioning reference setting: according to the design height, use the laser level to pop up the baseboard installation reference line;

[0033] S3. Installation and fixing: Choose any of the following fixing methods according to the curvature and weight of the skirting board:

[0034] If the wall surface is flat and the curvature of the skirting is small, use the gluing method: use epoxy resin glue or artificial stone special glue to apply dots on the back of the skirting, with the glue dots spaced 20-30cm apart. Attach the skirting to the wall reference line, tap and compact it, and then calibrate it with a laser level.

[0035] If the skirting is large-curved or heavy, the keel dry hanging method is used: or aluminum alloy brackets are used to form a metal keel, and pre-embedded hangers are fixed on the back of the light steel keel line according to the curvature of the wall at the skirting, and the hangers are inserted into the metal keel and reinforced with screws;

[0036] S4. Adjustment and joint treatment: Adjust the position of the skirting board after installation to ensure a tight fit, use caulking agent to repair the seams of the skirting board, and polish it to a smooth state.

[0037] In step S1, the flatness error of the repaired wall surface is ≤2 mm.

[0038] In the gluing method of step S3, during the pressing and adjusting process, a rubber hammer is used to tap the surface of the skirting board to achieve compaction.

[0039] In the keel dry hanging method of step S3, the installation spacing of the metal keels is adapted to the spacing of the pre-embedded hangers on the back of the skirting board, and the spacing between the keel fixing points is ≤50cm.

[0040] When the skirting board is a segmented structure, before step S3, the segmented skirting board is spliced ​​by using mortise and tenon joints in combination with gluing, and the splicing is done by using bevel splicing or invisible buckle design.

[0041] The length of a single section of the segmented skirting board is 5~10cm.

[0042] After the joint processing step in step S4, the method further includes the step of reserving expansion joints: reserving a gap of 1 to 2 mm at the corner between the skirting and the ground or wall.

[0043] Before step S1, the method also includes a water and electricity pipeline avoidance confirmation step: confirming the position of the water and electricity pipelines in the wall through a wall pipeline detector and marking the avoidance area.

[0044] In the keel dry hanging method of step S3, the metal keel is fixed to the wall surface using expansion screws, and the expansion screws are embedded in the wall to a depth of ≥5 cm.

[0045] The caulking agent is an artificial stone caulking agent that matches the material of the skirting board, and the joints need to be water-polished after treatment.

[0046] Working principle:

[0047] First, the water and electricity pipeline avoidance confirmation step uses a wall pipeline detector to locate the pipelines inside the wall and mark the avoidance area, avoiding damage to the pipelines during installation from the source and ensuring construction safety; the wall pretreatment cleans impurities and repairs uneven areas (ensuring the flatness error is ≤2mm) to provide a flat and fitting base surface for the skirting board, reducing loose installation or arc deformation caused by wall defects in the later stage.

[0048] Secondly, use a laser level to pop up the installation reference line to ensure the consistency of the height and curvature extension direction of the hyperbolic curved skirting, solve the offset problem of the curved structure due to visual errors, and provide a clear position reference for subsequent fixing links.

[0049] Furthermore, for flat walls, small curvatures, or lightweight skirting boards, the gluing method involves applying epoxy resin glue or artificial stone glue (with glue dots spaced 20-30 cm apart) to create discrete stress points. Lightly tapping and compacting with a rubber hammer ensures bond strength while preventing excess glue from overflowing and affecting the aesthetics. A laser level is also used for real-time calibration to ensure smooth curvature.

[0050] For large-curve or heavy-duty skirting boards, the dry-hanging method uses a metal keel (light steel or aluminum alloy bracket) that is clipped into the pre-embedded hangers on the back of the skirting board, and uses expansion screws (embedded in the wall to a depth of ≥5cm) to fix the keel. The keel spacing is adapted to the hanger spacing, and the spacing between fixing points is ≤50cm, forming a continuous load-bearing system that disperses the weight load and adapts to the mechanical requirements of the curved structure.

[0051] In addition, the segmented design with a single length of 5 to 10 cm is easy to adapt to the complex hyperbolic curvature. The mortise and tenon connection combined with the gluing splicing method (bevel splicing or invisible snaps) ensures the structural integrity between the segments, avoiding the problems caused by the direct use of a whole section of curved stone due to the difficulty in processing and easy damage in transportation, while ensuring the concealment and strength of the splicing.

[0052] Finally, the joints are repaired and polished with caulking agent to eliminate splicing marks and ensure a smooth surface. A 1~2mm expansion joint is reserved to provide expansion space for the skirting board when the temperature and humidity change, avoiding arching and cracking caused by thermal expansion and contraction of the material. The caulking and polishing of the joints further improve the overall sealing and aesthetics.

[0053] The entire process achieves the unity of aesthetics, stability and durability of the hyperbolic curved stone skirting board through the interlocking of early guarantees, precise positioning, adaptive fixation, structural integration and stress release.

[0054] Furthermore, in order to verify the machinability, mechanical properties, durability and construction convenience of the artificial stone hyperbolic curved skirting, the following experiments were designed and data support was provided:
