[0002] The solid wood floors sold in the domestic market at present are usually single-piece floors. Due to the single structure, they cannot be quickly and conveniently disassembled after installation, and at the same time, the decomposition of the internal stress of the solid wood floor cannot be solved, so the problem of floor deformation cannot be solved. At the same time, when the paved ground is uneven, the problem of the floor being suspended and unstable is likely to occur. The above floor deformation and the floor being suspended and unstable are likely to cause problems such as tile deformation, bulging, warping, trembling, and abnormal noise of the floor, which all affect the use of the solid wood floor and accelerate the deformation and aging of the solid wood floor. Especially when applied to sports venues such as basketball courts, badminton courts, and covered playgrounds, it will have a significant adverse impact. Summary of the Invention

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0031] In this application, unless otherwise specified or different meanings can be derived from the context, each term has the meaning commonly understood in the art.

[0032] On the one hand, the present application discloses a solid wood floor, which includes a plurality of floor boards and a leveling device disposed below the floor boards. It is characterized in that each floor board includes a plurality of single-strip floors that are spliced with each other, and a keel disposed below the single-strip floor and fixedly connected to the single-strip floor. The keel extends to the edge of the floor board and is adjacent to the keels of adjacent floor boards. The leveling device is disposed below the adjacent keels and bears the gravity of the keels.

[0033] In the present application, the floor board formed by "a plurality of single-strip floors that are spliced with each other" and "a keel disposed below the single-strip floor and fixedly connected to the single-strip floor" is used as the paving structural unit of the solid wood floor. Compared with the usual setting of the solid wood floor in the prior art, that is, taking a single-strip floor as the structural unit and sequentially fixing the single-strip floor on the keel pre-set on the ground, on the one hand, the above features in the present application maximize the area of the paving structural unit, thereby saving the paving process and reducing the construction cost. On the other hand, such a paving structural unit enables a stable connection to be formed successively between multiple single-strip floors and between multiple single-strip floors and the keel, and can decompose and offset the stress changes of the solid wood floor under the action of external forces or factors such as moisture absorption, effectively preventing the solid wood floor from deforming, and thus solving problems such as tile deformation, swelling, and warping. In the present application, the "single-strip floor" has the usual meaning understood by those skilled in the art and refers to the smallest structural unit of a solid wood board in the prior art, such as a long-strip solid wood floor, such as a solid wood board with a length of about 1800 mm and a width of about 70 mm. The term "splicing" refers to a stable connection between adjacent single-strip floors. The present application has no special restrictions on the number and connection method of the mutually spliced single-strip floors, as long as it is convenient to splice to form the floor board.

[0034] This application also defines that "the keel extends to the edge of the floorboard and is adjacent to the keel of the adjacent floorboard, and the leveling device is arranged under the adjacent keels", so that a leveling device can be shared between two adjacent floorboards, and it is very convenient to adjust the heights of adjacent floorboards in sequence during paving, eliminate the ground height difference, solve the problems of floor suspension caused by uneven ground in the prior art, floor vibration and abnormal noise when people walk on the floor, and further overcome the problem of deformation and aging of solid wood floors caused thereby. At the same time, such a setting does not require the overall leveling construction of the ground, which not only saves the construction cost, but also avoids the problem of accelerating the moisture absorption and deformation of solid wood floors due to the increase in ground humidity during construction. In this application, the term "adjacent" means that the end faces of two keels are in direct contact or close to each other, so that a leveling device arranged under two adjacent keels can act on two adjacent floorboards at the same time, facilitating the leveling of the floor height. In some preferred embodiments, the distance between the end faces of two adjacent keels is less than or equal to one-third of the size of the side of the leveling device in contact with the keel. In some preferred embodiments, the leveling device and the keel are fixedly connected, for example, by gluing, nailing, or screwing, which can further enhance the stability of the solid wood floor, and is particularly suitable for the solid wood floor of a sports field.

[0035] In some embodiments, the splicing method of the multiple single-strip floorboards is as follows: adjacent single-strip floorboards are connected by shape matching and / or gluing on the longitudinal side, and the keel forms a transverse fixed connection with the single-strip floorboard. Those skilled in the art understand that "splicing" usually adopts the method of "longitudinal connection", that is, the sides of adjacent single-strip floorboards are connected to each other in the length direction. For example, by opening male and female openings on the longitudinal side of the single-strip floorboard, shape matching connection can be achieved, or the longitudinal side can be glued, or a combination of the above two can form a stable splicing and have a good stress decomposition effect. The spliced single-strip floorboard and the keel adopt "transverse fixed connection", that is, the keel is fixed under the single-strip floorboard and extends along the width direction of the single-strip floorboard to form the floorboard. As a preferred embodiment, a single floorboard is provided with multiple keels, and the keels on both sides are close to the longitudinal edges of the floorboard to enhance the overall structural stability of the floorboard. In some other preferred embodiments, an equidistant relationship is formed between one of the keels on both sides of a floorboard and the keels arranged at other positions and the corresponding keels of the longitudinally adjacent floorboards, so that these keels can be adjacent to the corresponding keels of the laterally adjacent floorboards after installation and share the leveling device below. The side keels that do not form an equidistant relationship are only used to enhance the overall structural stability of the floorboard after installation. The specific fixing method of the keel can be nail fixing or shape matching connection of the contact surface fixing part. In some preferred embodiments, the cross-section of the shape-matching contact surface fixing part is an inverted trapezoid.

[0036] In some embodiments, the floorboard includes an upper keel layer and a lower keel layer. The upper keel and the lower keel are arranged perpendicular to each other, and a shock pad is provided at the intersection. The double-layer keel layer can further enhance the structural stability of the solid wood floor. By arranging the upper and lower keel layers vertically and providing a shock pad at the intersection, it not only ensures the high stability of the system structure and avoids the noise generated by the direct contact of the keels, but also ensures the vertical relative movement between the keels, provides sufficient elasticity, and improves the sports performance, especially suitable for high-level competitive sports venues.

[0037] In some embodiments, a protective layer is provided on the back surface of the floorboard. In this application, the "back surface" refers to the side of the floor close to the ground. The protective layer is a waterproof layer, or an insect-proof layer, a moisture-proof layer, etc. The waterproof layer can be a blister film or other waterproof materials. The waterproof layer covers the back surface, so as to protect the back surface and achieve the effects of moisture-proof, deformation-proof, insect-proof and anti-corrosion.

[0038] In some embodiments, the surface layer of the floorboard is treated with overall lacquering. Using overall lacquering can ensure a uniform paint surface. The paint is preferably a special wood floor paint, which has the characteristics of quick drying, anti-slip, wear-resistant, environmentally friendly, and non-reflective.

[0039] In some embodiments, the single-piece floor is made of any one of the following solid woods: oak, pine, maple birch, maple, beech, rubber wood. Each of the above solid wood types has its own advantages. The most prominent feature of oak is its high hardness, heavy material, and excellent bending resistance, and it can be widely used in basketball halls, badminton halls, multi-functional rooms, conference halls and other places. Pine has good elasticity, air permeability, good processing performance, smooth and bright surface after polishing, can well absorb paint and colorants, and has good bonding effect, which is very suitable for venues such as stages and conference rooms. The maple birch with a growth age of more than 30 years has good toughness, delicate and smooth texture, smooth cut surface, good painting and gluing performance, obvious annual rings, clear texture. Due to its extremely cold growth environment, it has immunity to pests and diseases, and has a high cost performance among all woods, and is widely used in basketball halls, badminton halls, stages, table tennis halls, volleyball halls, multi-functional rooms, conference halls, indoor football halls and other places. Maple is of moderate hardness, good stability, dense texture, good processing performance, smooth cut surface, bright and soft surface after polishing, good painting and gluing effects, not slippery and not astringent, and the texture is uniform and beautiful. It is an excellent choice for sports wood floors, and is widely applicable to indoor training or professional competition venues such as basketball halls, badminton halls, volleyball halls, table tennis, stages, etc., especially the first choice for event-level venues. The selection of the above woods are all embodiments applicable to the disclosed technical solutions of this application.

[0040] In some embodiments, the leveling device is a leveling base and / or a gasket. By providing the leveling device, when laying the plurality of floorboards, the height between the floorboards can be locally adjusted according to the undulation and slope changes of the ground, so as to adapt to the paving of complex sites. The leveling device can be selected from a leveling base or a gasket, or a combination of the above two. Among them, the leveling base can be selected for rotary screw leveling, and the gasket can be a load-bearing sheet with different thicknesses and shapes. Different specifications of gaskets can be selected according to the height to be adjusted to meet the requirements of load-bearing and leveling. In some preferred embodiments, the gasket is a rubber gasket or a wooden gasket. The rubber gasket can increase the elasticity of the floor while playing the leveling function. When applied to the solid wood floor of a sports field, it can improve the performance of the field and reduce the sports injuries of athletes. The rubber gasket is preferably a rubber product with good elasticity and anti-aging properties. In addition, the size of the rubber gasket should be greater than or equal to the width of the keel in addition to considering the height to be adjusted.

[0041] In some embodiments, adjacent floorboards are tightly connected through a locking device. The locking device includes: a fixed shaft point fixed to the back of the floorboard, a fixed positioning anchor point fixed to the back of another adjacent floorboard, and a locking spring connecting the fixed shaft point and the fixed positioning anchor point. Through the locking device, fixed connection between any adjacent floorboards can be achieved.

[0042] In some embodiments, adjacent floorboards are staggered from each other, and both ends of the locking device are respectively connected to the middle and the end of the adjacent floorboards. The two ends of the locking device refer to the fixed shaft point and the fixed positioning anchor point. Such a setting can further enhance the structural stability of the solid wood floor.

[0043] On the other hand, the present application discloses a method for preparing the solid wood floor, including the following steps:

[0044] Manufacturing floorboards: Multiple single-strip floors are spliced with each other, and the keel is fixedly connected to the multiple spliced single-strip floors to complete the assembly of the floorboards;

[0045] Laying floorboards: Laying the assembled floorboards, and a leveling device is arranged below the floorboards for leveling, wherein the leveling device is arranged below the adjacent keels and bears the gravity of the keels;

[0046] Setting up tight connection: Using a locking device to tightly connect between two adjacent floorboards.

[0047] The above steps can be carried out alternately.

[0048] The technical solution disclosed in this application forms stable connections in sequence between multiple single-strip floors and between multiple single-strip floors and the keels, which can decompose and offset the stress changes of solid wood floors under the action of external forces or factors such as moisture absorption, effectively preventing the solid wood floors from deforming, and thus solving problems such as tile deformation, swelling, and warping. At the same time, by setting a leveling device under the adjacent keels, the ground height difference is eliminated, solving the problems of floor suspension caused by uneven ground in the prior art, floor vibration and abnormal noise when people walk on the floor, and further overcoming the problem of deformation of solid wood floors caused thereby. The technical solution disclosed in this application also has various technical effects such as saving construction costs and being applicable to complex ground surfaces.

[0049] The above-mentioned ranges can be used alone or in combination. Through the following embodiments, it is easier to understand this application.

[0053] Figure 2 A single one of the floor boards 10 is shown, including five single-strip floors 11 spliced with each other, and five keels 12 provided under the single-strip floors 11. The single-strip floors 11 are spliced with each other along the length direction to form a longitudinal connection. The specific connection is as Figure 3 shown. A male opening and a female opening are sequentially opened on the longitudinal side surfaces of the single-strip floors 11 to achieve shape-fitting connection, and an adhesive is provided on the contact surface for adhesive connection to further enhance the stability between the single-strip floors 11. The five keels 12 are fixed with nails along the width direction of the single-strip floors 11 to form a transverse connection. The five keels 12 are equally spaced, and the two keels 12 at the edges are close to the longitudinal edges of the floor board 10, thereby enhancing the overall structural stability of the floor board 10 and effectively preventing problems such as tile deformation, swelling, and warping of the solid wood floor.

[0054] As Figure 4 and Figure 5As shown, the keel 12 extends to the edge of the floorboard 10 and is adjacent to the keels of adjacent floorboards.

The leveling device 20 is arranged below the adjacent keels 12, and the two keels 12 form a structure sharing the leveling device 20. The leveling device 20 includes a leveling base 21 and a gasket 22 arranged between the leveling base 21 and the keel 12. The leveling base 21 is leveled by rotating a screw, and the gasket 22 is an anti-aging elastic rubber pad.

Such a setting can also achieve many beneficial effects of the technical solution of this application and is suitable for uneven ground.

[0064] Embodiment 3

[0065] This embodiment provides a solid wood floor for another sports field. Its structural setting is basically the same as that of Embodiment 1. The difference is that, as Figure 9 shown, the distance between the end faces of the adjacent keels 12 is 5 cm. The leveling device only includes a gasket 22 made of an anti-aging rubber pad. The cross-sectional size of the keel 12 is 40 mm × 50 mm, and the cross-sectional size of the gasket 22 is 50 mm × 50 mm, so that there is sufficient contact area between the adjacent keels 12 and the gasket 22. The thickness of the gasket 22 is selected according to the ground height difference to level. Such a setting can also achieve many beneficial effects of the technical solution of this application and is suitable for uneven ground.
