Description

Technical Field

[0001] The utility model relates to the technical field of flooring, in particular to a base plate of a spliced ​​floor. Background Art

[0002] The spliced ​​floor generally includes a base plate and a decorative plate. The base plate is provided with a lock to splice the spliced ​​floors together, and the decorative plate is the surface that the user directly contacts. The main factors that determine the performance of the spliced ​​floor are the base plate and the lock. The structure and material selection of the base plate directly determine the performance and service life of the spliced ​​floor, and the design of the lock also seriously affects the convenience of splicing the spliced ​​floor and the stability after splicing. Therefore, the improvement of the spliced ​​floor in the prior art mainly focuses on the base plate and the lock.

[0003] There is a splicing floor in the prior art, which has male buckles on one pair of adjacent edges of the base plate, and female buckles on the other pair of adjacent edges. The male buckles of one splicing floor cooperate with the female buckles of another splicing floor to splice the two splicing floors. However, the male buckles and female buckles of the above-mentioned splicing floor are obtained by milling directly on the base plate. Since the contours of the male buckles and female buckles are complex and the dimensional accuracy requirements are high, high-precision cutting and milling equipment is required for cutting and milling during production, and the cost of purchasing production equipment is high. In addition, the splicing floor of the prior art generally uses stone powder as the base material, which has the disadvantage of being brittle. The male buckles or female buckles can be partially bent or broken by hand, resulting in local deformation, dark cracks or material falling due to bumps and other reasons during actual use, and the splicing cannot be completed. In addition, stone powder is water-absorbent. When there is water on the surface where it is laid, the water will penetrate into the splicing floor, causing the splicing floor to expand and deform, affecting the service life and user experience. The above problems can be solved if the base plate, male buckle and female buckle can be produced separately, and each uses a material that matches its functional requirements and has a higher cost-effectiveness. However, there are currently no similar products on the market, so it is necessary to improve the existing technology. Utility Model Content

[0004] The utility model aims to provide a substrate for a spliced ​​floor, aiming to solve at least one problem mentioned in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a substrate for a spliced ​​floor, which is in the shape of a flat rectangular parallelepiped, and its four edges are all provided with installation notches, the installation notches extend to the bottom surface and the side surfaces of the substrate, and an adhesive groove is provided in the installation notch, and the adhesive groove is recessed toward the direction where the top surface of the substrate is located. A solid baffle is also provided in the installation notch and is located on the outside of the adhesive groove.

[0006] Furthermore, the installation notches do not completely cover the entire edge of the substrate, and the edges located at the corners of the substrate are provided with avoidance notches, which are connected to the installation notches.

[0007] Furthermore, the width d1 of the installation gap is greater than the width d2 of the avoidance gap.

[0008] Furthermore, the width d2 of the avoidance gap is 2.5-4 mm.

[0009] Furthermore, the width d1 of the installation notch is 6-8 mm, and the width d3 of the bonding groove is 2.5-3 mm.

[0010] Furthermore, the width d4 of the solid baffle is 1.8-2.5 mm.

[0011] Furthermore, the bonding groove penetrates to the top surface of the substrate.

[0012] Furthermore, the side surface of the substrate is an inclined surface, and the arrangement of the inclined surface enables the substrate to form a structure that is larger at the top and smaller at the bottom.

[0013] Furthermore, the inclination angle ∠1 of the side surface is 8-10°.

[0014] Furthermore, the substrate is made of aluminum-plastic plate.

[0015] Compared with the prior art, the utility model provides a substrate for a spliced ​​floor. When producing the spliced ​​floor, the substrate and the male and female buckles are produced independently. Therefore, the substrate and the male and female buckles are made of different materials. Since the substrate only requires milling and has a simple structure, it can solve the problem of high cost of purchasing production equipment in the prior art. At the same time, the male and female buckles are produced separately, and high-strength materials can be selected for the male and female buckles separately. Therefore, the problem of easy damage of the male or female buckles in the prior art can be solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is a detailed description of the embodiments of the present utility model.

[0027] In this embodiment, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in this embodiment can be understood according to the specific circumstances. The directional words that appear in this embodiment are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of this embodiment changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0028] The utility model provides a substrate 1 for splicing a floor, such as Figures 1 to 7 As shown, it is in the shape of a flat rectangular parallelepiped, and its four edges are all provided with mounting notches 2, which extend to the bottom and side surfaces of the substrate 1, and an adhesive groove 3 is provided in the mounting notch 2, which is recessed in the direction of the top surface of the substrate 1, and a solid baffle 4 is also provided in the mounting notch 2 and is located on the outside of the adhesive groove 3. The extension to the bottom and side surfaces of the substrate 1 means that the mounting notch 2 passes through the bottom and side surfaces of the substrate 1, and also passes through the side surfaces of the substrate 1. After the male or female buckle is installed in the mounting notch 2, the side and bottom surfaces of the male or female buckle are not blocked by the substrate 1, so that the male buckle and the female buckle are exposed to achieve splicing. The setting method of the adhesive groove 3 can be as follows Figure 6 As shown, the bonding groove 3 is directly recessed in the direction of the top surface of the mounting notch 2 toward the top surface of the substrate 1, which directly forms the bonding groove 3. Figure 8 As shown, the solid baffle 4 is extended from the top surface of the installation notch 2 toward the bottom surface of the substrate 1. When the solid baffle 4 is extended, the bonding groove 3 is indirectly formed. Both of the above-mentioned settings fall within the protection scope of the present utility model.

[0029] Based on the above structural setting, when producing spliced ​​floors, the base plate 1 and the male and female buckles are produced independently, so the materials of the base plate 1 and the male and female buckles are different. For example, the base plate 1 adopts aluminum-plastic plate, PVC plate or plate with stone powder as the base material, while the male and female buckles adopt aluminum profiles, steel grooves or engineering plastic profiles, and the structure required for milling of the base plate 1 of the utility model is simple, which can solve the problem of high cost of purchasing production equipment in the prior art. At the same time, the male and female buckles are produced separately, and high-strength materials can be selected for the male and female buckles separately, so the problem of easy damage of the male or female buckles in the prior art can be solved.

[0030] When assembling the spliced ​​floor, a male buckle is installed in the installation notch 2 of one pair of adjacent edges, and a female buckle is installed in the installation notch 2 of another pair of adjacent edges. The male buckle and the female buckle are bonded to the substrate 1 by bonding, and the spliced ​​floor can be obtained. The setting of the bonding groove 3 provides an adhesive storage space to place more adhesive and improve the firmness of the bonding. At the same time, the bonding groove 3 is set in the form of a groove body and is formed with a solid baffle 4. The solid baffle 4 can also limit the outward movement of the male buckle and the female buckle, provide a certain blocking force, and prevent the male buckle and the female buckle from translating. Moreover, after a positioning structure matching the bonding groove 3 is set on the male buckle and the female buckle, the male buckle and the female buckle can be placed in the correct position more easily with the help of the bonding groove 3, which is conducive to improving the production efficiency of the spliced ​​floor. In actual production, the splicing structure of the male buckle and the female buckle can select any structure in the prior art that can achieve splicing by flooring.

[0031] In this embodiment, the installation notches 2 do not completely cover the entire edge of the base plate 1, and the edges at the corners of the base plate 1 are provided with avoidance notches 5, which are connected to the installation notches 2. The avoidance notches 5 are used to accommodate the protruding part of the lock buckle of another splicing floor when the end of one splicing floor is aligned with the middle of another splicing floor, that is, when the splicing is done in an I-shaped splicing or a step-by-step splicing. Only when the groove for avoiding the lock buckle is left, the I-shaped or step-by-step splicing can be realized, and the avoidance notch 5 can be directly milled on the base plate 1, which is very convenient to produce and has low production costs.

[0032] In this embodiment, the width d1 of the installation notch 2 is greater than the width d2 of the avoidance notch 5. The width d2 of the avoidance notch 5 is 2.5-4mm, the width d1 of the installation notch 2 is 6-8mm, the width d3 of the bonding groove 3 is 2.5-3mm, and the width d4 of the solid stop 4 is 1.8-2.5mm. Preferably, the width d1 of the installation notch 2 is 6mm, the width d2 of the avoidance notch 5 is 3mm, the width d3 of the bonding groove 3 is 3mm, and the width d4 of the solid stop 4 is 2mm. The above is the optimal size selection after comprehensively considering the convenience of assembly and the strength during use.

[0033] In this embodiment, if Figure 6 As shown, the side of the base plate 1 is an inclined surface, and the setting of the inclined surface makes the base plate 1 form a structure with a larger top and a smaller bottom. Based on the setting of the inclined surface, the top of the inclined surface is used to provide the deformation required for assembly, which can make the splicing resistance of the spliced ​​floor smaller and the splicing operation easier. When the splicing is completed, the top of the inclined surface rebounds, so that the two spliced ​​floors are pressed against each other, eliminating the gap, and making the joint after splicing more perfect. Preferably, the inclination angle ∠1 of the side is 8-10°.

[0034] In this embodiment, the base plate 1 is made of aluminum-plastic plate. Aluminum-plastic plate has low water absorption, is not easy to deform, and has good thermal conductivity. It is a good choice as the base plate 1 of the spliced ​​floor, especially in the north where floor heating is needed and in the south where the ground is humid. However, the common adhesives on the market have poor adhesion to aluminum-plastic plates. If the male and female buckles are bonded to the aluminum-plastic plates, the male and female buckles are easy to fall off. Especially when the spliced ​​floor needs to be dismantled after splicing, when a piece of spliced ​​floor is pulled up, the male or female buckles may be detached from the base plate 1, so that the spliced ​​floor is directly scrapped and cannot be reused. For this reason, if Figure 7 As shown, this embodiment provides a further preferred solution, specifically, the adhesive groove 3 is penetrated to the top surface of the substrate 1. In this way, when producing the spliced ​​floor, the decorative board is bonded to the top surface of the substrate 1. Based on the setting that the adhesive groove 3 penetrates to the top surface of the substrate 1, the adhesive is bonded between the male buckle / female buckle and the decorative board. The decorative board is generally made of PVC board, wood board, etc. These boards have good adhesion with common adhesives on the market, that is, the bonding basis of the male buckle and the female buckle is changed from aluminum-plastic board to decorative board, so that the connection between the male buckle and the female buckle and the whole spliced ​​floor is very stable and not easy to fall off. Of course, in actual production, it can also be as follows Figure 5 The bonding groove 3 shown does not penetrate to the top surface of the substrate 1, and the bonding base of the male buckle and the female buckle is the substrate 1. In this case, the substrate 1 preferably does not use aluminum-plastic panels, but uses common materials of traditional spliced ​​floors, such as PCV panels or panels with stone powder as the base material.

[0035] In summary, this type of substrate 1 can solve the problem of high cost of purchasing production equipment in the prior art, and can also solve the problem of easy damage of male buckles or female buckles in the prior art.

[0036] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the preferred technical solutions of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solutions of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the utility model.
