Description

Technical Field

[0001] This invention relates to the field of building floor decoration, and in particular to the splicing structure and construction method of small-sized thick arc-shaped granite floor. Background Technology

[0002] In outdoor landscaping, garden walkways, plaza paving, and other construction projects, granite is widely used for ground decoration and paving due to its advantages such as high hardness, good wear resistance, beautiful texture, and strong weather resistance. To enhance the overall aesthetic appeal of the ground, granite slabs are often spliced ​​together to form artistic patterns such as arcs and irregular shapes to meet the needs of landscape decoration design.

[0003] Currently, small-sized, thick granite slabs are commonly used for landscape paving, with a standard size of 200mm×200mm×50mm. These slabs are small in size but large in thickness. In actual processing, large CNC cutting equipment struggles to precisely cut the curved edges of the slabs, resulting in poor processing adaptability. On the other hand, on-site manual cutting easily leads to processing defects such as chipped edges, burrs, missing corners, and irregular contours, resulting in low slab forming precision.

[0004] After traditional granite flooring is laid, the flaws and defects of the cut slabs are directly exposed and cannot be concealed, resulting in rough splicing lines, poor pattern continuity, and a significant reduction in the overall decorative effect. Furthermore, it cannot withstand the complex conditions of outdoor exposure to sunlight, rain, and fluctuating temperatures, and is prone to cracking, detachment, and water seepage after long-term use. This not only affects the aesthetics of the floor but also causes water accumulation in the paving layer, loosening of the base layer, and reduces the overall lifespan and structural stability of the flooring structure. Summary of the Invention

[0005] The main objective of this invention is to provide a splicing structure and construction method for small-sized thick arc-shaped granite pavement, in order to solve the technical problems of exposed cutting defects in existing small-sized thick shaped granite pavement, which are prone to cracking, falling off, and water seepage after long-term use.

[0006] To achieve the above objectives, the present invention provides a small-sized, thick-shaped granite floor splicing structure, comprising:

[0007] The first granite slab has a first-shaped cut edge.

[0008] The second granite slab has a second shaped cut edge. The second granite slab is located on one side of the first granite slab, with the second shaped cut edge and the first shaped cut edge spaced apart and opposite to each other, forming a splicing seam corresponding to the target shape. The width of the splicing seam is 12-18 mm.

[0009] Sealing strips are used to fill the splicing gaps.

[0010] According to an embodiment of this application, the material of the sealing strip is silicone weather-resistant sealant.

[0011] According to an embodiment of this application, the sealing strip is an opaque sealing strip.

[0012] According to an embodiment of this application, the edges of the first shaped cutting edge and the edges of the second shaped cutting edge have arc-shaped structures, and their outlines are completely matched.

[0013] According to the embodiments of this application, the maximum dimensions of the length and width of the first granite slab and the second granite slab are no greater than 200 mm, and the thickness of the first granite slab and the second granite slab is 40~60 mm.

[0014] According to an embodiment of this application, the sealing strip fills the splice seam completely in the height direction of the splice seam.

[0015] According to an embodiment of this application, it further includes an adhesive layer, on which the first granite slab, the second granite slab, and the sealing strip are disposed.

[0016] According to an embodiment of this application, the adhesive layer is prepared using a 1:3 dry-hardened cement mortar, and the height of the adhesive layer is 30~40mm.

[0017] The aforementioned small-sized, thick-slab decorative granite pavement splicing structure employs a 12-18mm widened joint structure. This completely conceals defects such as chipped edges, burrs, and contour deviations caused by the manual cutting of small-sized, thick granite slabs, thoroughly resolving the problems of exposed flaws and a rough appearance associated with traditional paving. The widened joints, combined with sealing strips, refine and standardize the overall design lines, ensuring smooth and continuous curves and irregular shapes. Simultaneously, the sealing strips completely fill and seal, preventing rainwater from seeping into the paving base layer, enhancing the pavement's impermeability, and making it suitable for complex outdoor environments.

[0028] The embodiments of this application provide a splicing structure for small-sized, thick-shaped granite flooring, referring to... Figure 1 and Figure 2 It includes a first granite slab 100 and a second granite slab 200. The first granite slab 100 is provided with a first shaped cut edge 110, and the second granite slab 200 is provided with a second shaped cut edge 210. The second granite slab 200 is arranged on one side of the first granite slab 100, so that the second shaped cut edge 210 and the first shaped cut edge 110 are arranged opposite each other at intervals, thereby forming a splicing seam that matches the target shape. The width of the splicing seam is controlled to be 12~18mm, and the gap of the splicing seam is filled with a sealing strip 300.

[0029] The inventors discovered that, for outdoor paving scenarios using small-sized, thick, curved granite (200×200×50mm), the industry's traditional 2-5mm narrow-joint paving process has unavoidable structural defects, making it difficult to balance construction quality, appearance, and outdoor durability.

[0030] First, traditional filling materials have extremely poor adaptability. Most of them use rigid cement mortar and ordinary grout. These materials are all rigid and have no elastic deformation ability. They are prone to cracking and falling off when faced with outdoor temperature changes and slight settlement of the base layer, which can lead to water seepage risks.

[0031] Secondly, narrow-slit structures have inherent construction defects. The filler material itself has a certain viscosity, and the narrow space of the slit prevents the filler material from penetrating deep into the slit, resulting in only shallow filling and easily causing quality problems such as voids and poor adhesion. In particular, when the filler material is replaced with weather-resistant adhesive, the viscosity of the weather-resistant adhesive is relatively high, and the narrow space of the caulking gun prevents it from penetrating deep into the slit, making problems such as voids and poor adhesion even more serious.

[0032] Furthermore, due to limitations in equipment clamping and cutting processes, small-sized, thick stone slabs inevitably suffer from processing errors such as chipping, burrs, and misalignment during construction. Traditional narrow joints, with widths less than the maximum processing tolerance of the stone, offer extremely low margins of error, failing to accommodate inherent processing defects. This ultimately results in messy and irregular curved lines after installation. The industry can only remedy this by relying on high-precision cutting and manual grinding, significantly increasing processing and construction costs.

[0033] At the same time, the narrow gap structure has a small amount of adhesive filling and a thin adhesive layer, resulting in a double lack of function. It cannot fully cover the rough vertical sides of the stone to achieve the effect of concealing and modifying the appearance, nor does it have sufficient elasticity to buffer the stress of outdoor structures. Its waterproof, deformation resistance and weather resistance are seriously inadequate.

[0034] To address the aforementioned technical shortcomings, this invention abandons the industry's traditional narrow-joint paving approach and innovatively adopts a combination of 12-18mm wide joints and sealing strips 300. The wide joint structure provides ample construction space and error tolerance, while the thick sealing strips 300 fully fill and shape the entire structure, completely concealing stone cutting defects and creating a continuous and smooth curved overall appearance. At the same time, relying on the high elasticity, anti-aging, and waterproof properties of the adhesive, it effectively buffers structural deformation stress and is suitable for outdoor all-weather conditions.

[0035] In this application, reference is made to Figure 1 and Figure 2The first granite slab 100 and the second granite slab 200 are the main decorative load-bearing components of the ground paving. The first shaped cut edge 110 and the second shaped cut edge 210 opened on the side respectively cooperate with each other to fit the arc or irregular target shape required by the design, so as to meet the needs of landscape ground shape design.

[0036] The shaped edge is the outline of the side of the board. It is the basic structure for splicing two boards together. The continuous shaped lines are achieved by the mutual alignment and cooperation of the two sides of the shaped edge.

[0037] The 12~18mm widened splicing joints differ from traditional narrow-joint paving. They can effectively contain and cover processing defects such as chipped edges, burrs, and irregular contours caused by manual cutting of boards, greatly reducing the requirements for board processing precision. The 300 sealing strip is filled inside the splicing joint to seal the joint and connect the shapes of the boards on both sides, making the overall shape lines smooth and unified, while also serving to prevent water seepage, weathering, and cracking.

[0038] This structure abandons the traditional narrow-joint, close-fitting process, adopting a 12-18mm widened decorative joint structure. This completely covers defects such as chipped edges, burrs, and contour deviations caused by hand-cutting small-sized, thick granite slabs, thoroughly solving the problems of exposed flaws and rough appearance in traditional paving. The widened joints, combined with 300mm sealing strips, can refine and standardize the overall shape lines, ensuring smooth continuity of curved and irregular shapes. At the same time, the sealing strips completely fill and seal, preventing rainwater from seeping into the paving base layer, improving the ground's impermeability, and making it suitable for complex outdoor environments.

[0039] In some embodiments, the sealing strip 300 is made of silicone weather-resistant sealant.

[0040] Silicone weather-resistant sealant has excellent resistance to high and low temperatures, aging, ultraviolet rays, and rain erosion. It also has excellent adhesion, elasticity, and crack resistance, making it a special sealing material for outdoor paving.

[0041] Silicone weather-resistant sealant is suitable for complex outdoor conditions such as sun exposure, rain, and fluctuating temperatures. It is not prone to aging, cracking, or peeling with long-term use, solving the problems of poor weather resistance and easy failure of traditional caulking materials. At the same time, the material has excellent elasticity, which can adapt to the thermal expansion and contraction deformation of the board, avoiding cracking and water seepage at the joints, and greatly improving the durability of the floor paving.

[0042] In some embodiments, the sealing strip 300 is an opaque sealing strip.

[0043] Opaque sealing strips have a light-blocking and covering effect, and can completely cover the edge defects of the back panel and the gaps in the base layer.

[0044] Opaque sealing strips can completely cover the side cutting defects, minor gaps and debris in the substrate, and the joints are uniform in texture and free of light-transmitting flaws, further enhancing the overall aesthetics of the floor and ensuring a neat and orderly appearance.

[0045] In some embodiments, refer to Figure 1 and Figure 2 The edges of the first shaped cutting edge 110 and the second shaped cutting edge 210 are both set as arc structures, and their outlines are completely matched.

[0046] Compared to conventional straight-line cut-edge paving structures (such as zigzag designs), the curved sides of small-sized, thick granite slabs are extremely difficult to process. Thick slabs are rigid and have a small surface area, making them prone to processing defects such as curvature deviation, local chipping, and uneven curves during the curved cutting process. In this way, traditional narrow-joint paving will completely expose all kinds of processing defects, resulting in a very poor appearance.

[0047] This structure, through a matching arc-shaped cut edge and a 300mm wide sealing strip transition design, can effectively accommodate the curvature error and edge defects caused by arc cutting, and avoid the problem of insufficient processing precision of small-sized thick plates. After molding, it can form a smooth, rounded, and continuous arc shape without fold lines or misalignments, perfectly adapting to the design requirements of landscape arc-shaped ground shapes. It significantly reduces the processing precision requirements and construction difficulty of arc-shaped paving materials, and has significant adaptability and molding advantages in high-difficulty arc-shaped paving scenarios.

[0048] In some embodiments, refer to Figure 1 and Figure 2 The length and width of the first granite slab 100 and the second granite slab 200 shall not exceed 200mm, and the thickness of the slab shall be set to 40~60mm.

[0049] This small-sized, thick-shaped granite flooring splicing structure is compatible with commonly available 200mm×200mm×50mm granite slabs and other sizes of granite slabs.

[0050] This structure specifically addresses the industry pain points of special plates with a thickness of 40-60mm and a diameter of less than 200mm, which are difficult to machine and prone to defects when handled manually due to their small size and large thickness. The thick plate structure floor has good compressive strength and wear resistance, long service life, and is suitable for outdoor pedestrian and light load conditions.

[0051] In some embodiments, refer to Figure 1 and Figure 2 The sealing strip 300 is fully installed along the height of the splice joint, completely covering the internal space of the splice joint.

[0052] The sealing strip is 300mm full-sealing setting to achieve full-height sealing of the splice joint.

[0053] The seam is fully filled without gaps or delamination, completely eliminating problems such as water seepage, dust accumulation, and dirt trapping at the seams, providing the best sealing and waterproofing effect; at the same time, the integrally formed rubber strip structure has strong integrity, uniform stress distribution, and is not prone to local cracking and falling off, resulting in better structural stability.

[0054] In some embodiments, refer to Figure 1 and Figure 2 The granite floor splicing structure also includes an adhesive layer 400, and the first granite slab 100, the second granite slab 200 and the sealing strip 300 are all laid and fixed on the adhesive layer 400.

[0055] The 400 bonding layer is the overall paving base bonding structure, used to uniformly bond and fix the granite slabs, ensuring that the slab surface is flat and the positioning is firm.

[0056] It can effectively prevent small-sized boards from shifting, becoming hollow, or warping, ensuring the flatness and structural integrity of the overall floor paving.

[0057] In some embodiments, the adhesive layer 400 is prepared using a 1:3 dry-hardened cement mortar, and the thickness of the adhesive layer 400 is controlled to be 30~40mm.

[0058] The bonding layer is made of a 1:3 dry-hard cement mortar mixture, with a cement to medium-coarse sand volume ratio of 1:3. The mortar is dry-hard, forming a clump when squeezed but crumbling upon contact with the ground. The 400mm material and thickness of this bonding layer ensure strong adhesion and uniform stress distribution to the slabs, making it suitable for the self-weight of thick granite slabs. This effectively prevents hollow areas, detachment, settlement, and deformation, thus improving the overall quality of the floor paving.

[0059] In some embodiments, the construction method for small-sized, thick-shaped granite floor splicing structures includes the following steps:

[0060] First, according to the construction target shape, the granite slabs are cut and processed to form a first granite slab 100 with a first shape cut edge 110 and a second granite slab 200 with a second shape cut edge 210.

[0061] The two granite slabs are then positioned and fixed in the target construction area, with the first shaped cut edge 110 and the second shaped cut edge 210 arranged at intervals to form a splicing joint with a width of 12~18mm.

[0062] Finally, the sealant is injected into the joint, and after curing, it forms a 300-inch sealant strip.

[0063] This construction method employs a step-by-step process: first, shaping and cutting; then, positioning and laying; and finally, sealing with adhesive. It is well-suited for the construction of small-sized, thick slabs, and features a simple procedure with high tolerance for error. This method is concise and easy to operate, eliminating the need for high-precision CNC cutting equipment, thus reducing processing difficulty and construction costs. By pre-reserving widened joints and then uniformly applying adhesive, it offers high tolerance for error, allows for batch construction, high efficiency, uniform and neat shapes, and strong quality control.

[0064] This construction method is simple and easy to operate, requiring no high-precision CNC cutting equipment, thus reducing processing difficulty and construction costs. By reserving widened joints and then uniformly injecting glue to form the shape, it has a high error tolerance, can be carried out in batches, has high construction efficiency, produces uniform and neat shapes, and has strong quality control.

[0065] In some embodiments, the joint sealant is injected in layers at a uniform speed.

[0066] This construction process employs a refined sealing technique, using multiple, uniformly filled applications to effectively avoid molding defects caused by single-application. The layered, uniform-speed application process effectively removes air from the adhesive layer, preventing air bubbles, voids, and adhesive breaks, ensuring the sealing strip is dense, full, and uniformly applied. The layered molding process also results in stronger adhesion, reducing shrinkage and cracking, further improving the sealing and waterproofing quality of the joints and the smoothness of the appearance.

[0067] The layered, uniform-speed adhesive injection process effectively removes air from the adhesive layer, preventing defects such as bubbles, hollow areas, and adhesive breaks, ensuring that the sealing strip is dense, full, and uniform. The layered molding process also results in stronger adhesion, making it less prone to shrinkage and cracking, further improving the sealing and waterproofing quality of the joints and the smoothness of the appearance.

[0068] In some embodiments, the construction step of injecting sealant into the joint includes:

[0069] S1. Joint pretreatment: After the stone adhesive layer has initially set at 400mm, clean the debris and water inside the joint and dry the joint walls to ensure they are dry and clean.

[0070] S2, Layered Injection: Use opaque solid-color silicone weather-resistant sealant to inject layered and uniformly from the seam end to the seam tail. The sealant fully fills the entire seam space above the foam rod, without any voids or air bubbles.

[0071] S3. Curing and maintenance: Let stand at room temperature for 72 hours until the sealant is fully cured. Avoid stepping on it or soaking it in water during the curing period.

[0072] In some embodiments, the present invention employs a split-type splicing structure of small-sized, thick granite slabs. Matching shaped cut edges are processed on the sides of adjacent granite slabs, and the two slabs are spaced apart to form a widened splicing joint of 12-18mm. This widened joint accommodates processing defects such as chipped edges, burrs, and contour deviations caused by manual cutting of the slabs. An opaque, weather-resistant silicone sealant is fully filled into the splicing joint to form a continuous sealing strip 300, concealing side imperfections and maintaining neat shaped lines. Simultaneously, the excellent weather resistance and elasticity of silicone material adapt to outdoor temperature variations and rain erosion conditions, achieving waterproofing, crack resistance, and aging resistance in the splicing joint. Combined with a bottom adhesive layer 400 for overall bonding and fixation, this ensures the slabs are laid flat and firmly, ultimately forming a granite shaped floor with a smooth shape, excellent appearance, stable structure, and suitability for outdoor conditions.

[0073] Overall beneficial effects of the invention

[0074] Compared with the prior art, the present invention has the following significant advantages:

[0075] 1. Effectively conceals processing defects and enhances decorative appearance: Addressing the pain points of small-sized thick granite slabs being difficult to process mechanically and prone to defects by hand, a 12-18mm wide joint design is adopted, which, together with opaque sealing strips, completely covers defects such as chipped edges, burrs, and irregular outlines of the slabs, thoroughly solving the problem of exposed defects in traditional narrow-joint paving. The ground surface has smooth and uniform lines and a significantly improved aesthetics.

[0076] 2. Weather-resistant and waterproof, suitable for outdoor conditions: The sealant is filled with silicone weather-resistant sealant. The material has excellent resistance to ultraviolet rays, aging, and temperature deformation. It is not easy to crack, fall off, or leak after long-term outdoor use, solving the problems of poor weather resistance and easy failure of traditional sealant materials, and greatly extending the service life of the ground paving.

[0077] 3. High construction tolerance and low cost: No high-precision CNC cutting equipment is required; on-site manual cutting and processing can be used, reducing equipment investment and processing costs; the widened joint has a large tolerance space, making construction easier, the forming quality stable, and batch construction can be carried out efficiently.

[0078] 4. Strong overall structure and good stability: With the bottom adhesive layer 400 for overall fixation, the boards are not easy to hollow, shift, or warp; the full-sealed and dense adhesive strip structure can effectively seal the gaps, prevent water accumulation, efflorescence, and soaking of the base layer, and significantly improve the stability of the ground paving structure.

[0079] 5. Wide adaptability: The double-sided matching shape cut edge can be adapted to curved and various irregular landscape shapes. The splicing and forming has good continuity and can meet the design needs of various outdoor landscape ground shapes. It has strong versatility.
