According to Republic of Korea Patent Application No. 10-2015-0109335, prefabricated molded flooring that can be used for sports coats by assembling a plurality of flooring consisting of a plastic block has been proposed. However, according to the flooring of the prior art, when assembling a thing having a square, it should be able to accurately set the left and right or up and down directions, it is very easy to distinguish the direction of the flooring to be assembled or to prevent the misassembly of the changed state No fundamental measures are in place.

And there is an advantage that can be easily installed by making a number of floor blocks by using a synthetic resin material, assembling a number, but the overall strength is not satisfactory compared to the complicated structure and has a configuration that is not so preferable in terms of post-treatment.

And in general, the prefabricated flooring, it is natural that it is required that the assembled state is easy to have a solid structural strength. Here, the flooring may be partially damaged by fatigue load due to prolonged use or by a large load of structural strength or higher. Therefore, it is necessary to be able to easily separate the flooring partly even if some of the floorings installed in the large area are damaged. However, since the conventional flooring is somewhat lacking in the structure for decomposition, there is a disadvantage that it is not easy to partially separate what is in between.

The present invention has been made in view of the disadvantages of such a conventional flooring, and the main object of the present invention is to provide a flooring that can improve the assemblability by easily recognizing the correct assembly direction when assembling the rectangular flooring. And this purpose can be said to have the same meaning that it can substantially prevent the assembly in the wrong direction.

It is a further object of the present invention to provide a prefabricated flooring which is easy to partially separate the floorings such that sufficient structural strength can be maintained in the bonded state.

It is a further object of the present invention to provide a structurally rigid prefabricated plastic flooring which can have sufficient support strength against loads applied from the top.

The prefabricated flooring material of the present invention is constituted by a rectangular frame having a plurality of units continuously formed up, down, left and right, and having an outer wall composed of an upper wall and a lower wall and a first side wall and a second side wall. In addition, a plurality of legs may be formed on the bottom of the rectangular frame to be maintained at a predetermined height on the ground. In addition, the left and right coupling grooves are formed on one side of the first side wall and the second side wall, and the left and right coupling protrusions are coupled to the left and right coupling grooves on the other side. The vertical coupling protrusion coupled to the vertical coupling groove may be molded to be coupled in a state of being in continuous contact with an adjacent square frame. Here, the left and right coupling protrusions have a different shape from the up and down coupling protrusions, so that the coupling direction such as the up and down direction or the left and right directions can be easily recognized and, of course, incorrect misassembly is not allowed.

According to an embodiment of the present invention, the left and right coupling protrusions and the vertical coupling protrusions are formed of an extension fitting portion extending outward from the upper wall, the lower wall, or both side walls of the square frame, and a head formed at the end of the extension fitting portion. . The left and right coupling grooves and the vertical coupling grooves are formed on the upper wall, the lower wall, or both side walls of the square frame, and the outer coupling grooves to which the extension fittings are coupled, and the head coupling grooves into which the heads of the left and right coupling protrusions and the vertical coupling protrusions are inserted. . Here, the head of the left and right coupling protrusions and the head of the up and down coupling protrusions may be molded to have different shapes, and the extension fitting portions of the left and right coupling protrusions and the extension fitting portions of the vertical coupling protrusions may be molded to have different shapes. .

According to another embodiment of the present invention, the extension fitting portion of the left and right coupling protrusions and the up and down coupling protrusions and the outer coupling grooves of the left and right coupling grooves and the up and down coupling grooves may be coupled by interference fit. Alternatively, the head of the left and right coupling protrusions and the up and down coupling protrusions and the head coupling grooves of the left and right coupling grooves and the up and down coupling grooves may be coupled by interference fit.

According to another embodiment, the fitting protrusion is formed on the outside of the extension fitting portion of the left and right coupling protrusion and the vertical coupling protrusion, the fitting groove is formed inside the outer coupling groove of the left and right coupling groove and the vertical coupling groove, the fitting protrusion The coupling groove is configured to be combined into an interference fit.

According to a more specific embodiment of the present invention, the inclined surface for the guide at the time of insertion is formed on the lower end of the fitting protrusion, the inclined surface for separation is formed on at least a part of the upper end of the fitting protrusion.

According to the present invention as described above, by having the left and right coupling projections and the vertical coupling projections used to assemble the flooring in the vertical direction or the left and right directions to have a different shape, the orientation of the assembly can be easily recognized, and misassembly is allowed. It is configured not to be. Therefore, it can be expected that the effect that the more efficient assembly work is possible.

And according to the present invention, when assembling the flooring consisting of a square frame, it can be seen that the coupling protrusion is coupled to the interference fit (Interference fit) when fitted into the coupling groove. Therefore, compared with the hook coupling, etc., it is possible to have sufficient structural strength in the substantially bonded state. And this point is expected to be able to substantially secure the durability of the prefabricated flooring of the present invention.

In the present invention, the inclined surface is formed in at least part of the fitting protrusion in addition to the insertion (coupling) direction. Therefore, it is relatively easy to separate some of the flooring materials arranged in plural on the plane. As described above, being able to easily remove a part of the flooring material may mean that some damage caused by use after installation can be easily repaired and replaced in part.

The unit formed inside the square frame of the flooring of the present invention is formed to have a hexagonal shape (honeycomb shape), thereby distributing and supporting the load by external force. Therefore, it can be expected to have the ultimate structural strength against the external force. This structural strength can be said to have substantially the same meaning as can substantially secure the durability of the prefabricated flooring of the present invention.

Next, the present invention will be described in more detail with reference to the embodiments shown in the drawings.

As shown in Figure 1, the flooring material 10 of the present invention is made of a synthetic resin material and has a square. Thus, the flooring material 10 is formed to have a quadrangular shape as a whole, and the width may be expanded by combining a plurality of pieces in the vertical direction and the horizontal direction based on FIG. 1. In addition, the inside of the rectangular frame 20 of the flooring 10 has a structure in which a plurality of units 12 for supporting a load applied from the top to the bottom are continuously repeated vertically and horizontally.

As described below, the square frame 20 of the flooring material of the present invention is formed on both sidewalls (the first side wall 22A and the second side wall 22B), the upper wall 24A formed on the upper side, and the lower side. A lower wall 24B is provided. Units arranged inside the rectangular frame 20 are formed in succession by repeating substantially in the left, right, up and down directions. In the illustrated embodiment, the unit 12 exemplarily shows a hexagonal unit, and it can be seen that the hexagonal unit 12 is repeatedly formed in the vertical direction and the left and right directions in FIG. 1.

As described above, the rectangular frame 20 having the units 12 vertically and vertically disposed in the inside is generally made into a square. However, in the case of making a square rectangular frame 20 in this way, it is preferable to make it easy for the worker to know the direction when assembling. In addition, when making the square rectangular frame 20 it can be said that it is also important to configure so as not to be assembled in the other direction.

While describing the flooring 10 of the present invention in the present invention, the overall direction and the like will be described with reference to the direction shown in FIG. The flooring material 10 of the present invention, which is injection-molded with synthetic resin, should be formed in a horizontal plane so that sports can be formed on the upper surface and form a horizontal plane even when several pieces are assembled. On the bottom face of the flooring 10, a plurality of legs 11 extending downward are molded, for example, formed at each corner of the hexagonal unit 12. As shown in FIG. In the following description of the present invention, the unit 12 formed inside the rectangular frame 10 will be described taking the hexagonal unit as shown as an example.

The upper surface of the flooring material 10 which is supported on the ground by a plurality of legs 11 described above at a predetermined distance can maintain a horizontal plane. And a predetermined gap is formed between the unit 12 of the present invention itself and the hexagonal unit 12 arranged in series, such a gap can have a function such as draining rainwater or falling of foreign matter, unit 12 It may be possible to perform this function even if this hexagon is not. And as will be described later, both sides and the upper and lower surfaces of the square frame forming the outer surface of the flooring 10 is to have the same height as the legs described above, of course, it is of course possible to lose weight according to the needs of injection molding.

Next, a structure for connecting the flooring 10 having the hexagonal unit 12 arranged in a plane in the left and right directions will be described. In order to continuously assemble the flooring 10 shown in FIG. 1 in the left and right direction, the left and right coupling grooves 32 are formed in the first side wall 22A at regular intervals, and the left and right coupling grooves are formed in the second side wall 22B. A plurality of left and right coupling protrusions 34 coupled to 32 are formed at the same intervals, respectively.

Referring to the embodiment of forming the inner unit 12 of the rectangular frame 20 into a hexagonal unit, as shown in the embodiment shown in Figure 1, the two units in the vertical relationship among the hexagonal units arranged on the right side Referring to (12, 12a), the outer surfaces 14, 14a vertically arranged in the two units 12, 12a become the first side walls 22A forming the rectangular frame 20 as described above. , Between them, a triangular space 32 is formed, which will be used as a left and right coupling groove 32.

Referring to the two units 12 and 12a having a vertical relationship among the hexagonal units arranged at the leftmost side in FIG. 1, for example, the outer surfaces 13 and 13a vertically arranged at the two units 12 and 12a are illustrated. Is formed on the same surface as the second side wall 22B forming the rectangular frame 20. Here, the left and right coupling protrusions 34 are formed in the portion of the second side wall 22B forming the outer surface between the two upper and lower units 12 and 12a, which correspond to the positions of the left and right coupling grooves 32. That is, in the present invention, the left and right coupling grooves 32 are formed by using the space between the outer surfaces of the pair of upper and lower hexagonal units constituting the square frame 20 on one side in the up and down engagement of the flooring 10. On the other side, it can be seen that the coupling protrusion 34 of the shape corresponding to the coupling groove 32 is formed.

3 to 5 will be described in more detail with respect to the configuration associated with the left and right coupling projection (34). 3 is a perspective view from above of part A of FIG. 1, FIG. 4 is a perspective view from below of part B of FIG. 1, and FIG. 5 is a bottom view of part B of FIG. 1. The left and right coupling protrusions 34 of the present invention include an extension fitting portion 34b extending outwardly from the second side wall 22B and a head 34a extending outwardly from an end of the extension fitting portion 34b. . And the left and right coupling groove 32 is composed of a head coupling groove 32a into which the head 34a is inserted and an outer coupling groove 32b to which the extension fitting portion 34b is coupled.

And when they are coupled, the head 34a of the left and right coupling protrusions 34 is coupled while being inserted into the head coupling groove 32a of the first side wall 22A. At this time, the extension fitting portion 34b (see FIG. 3) of the left and right coupling protrusions 34 enters into the outer coupling groove 32b (see FIG. 4) formed in the first side wall 22A. As described above, the state in which the left and right coupling protrusions 34 are coupled to the left and right coupling grooves 32, that is, the head 34a is coupled to the head coupling grooves 32a is illustrated in FIG. 6.

When the left and right continuous flooring 10 is coupled, it is obvious that the structural strength of the portion actually joined is the weakest. Therefore, as shown in Figure 6, when having a coupling, the left and right engaging projection 34 is most preferably coupled to the left and right coupling groove 32 by interference fit. That is, it can be said that it is preferable to combine the left and right coupling projections 34 and the left and right coupling grooves 32 in the flooring material 10 made of a synthetic resin by force fitting so that both can be elastically deformed little by little. .

And the flooring of the present invention is also important structural strength to withstand the external force in the construction state, but should be configured to be able to disassemble the part assembled in the middle and replace it with a new flooring when partially damaged. For example, when applying a hook structure coupled to lock in one direction (locking), it is easy to engage compared to the interference fit, but it is impossible to disassemble the flooring in the middle, there is a problem in the post-management.

As can be seen with reference to FIGS. 4 and 5, the fitting protrusion 34d is formed at the middle portion in the vertical direction of the extension fitting portion 34b of the left and right coupling protrusion 34 formed on the second side wall 22b. have. And on the opposite surface of the outer engaging groove 32b formed in the first side wall 22A, which may be called the neck in the left and right coupling groove 32, the fitting groove 22D forcibly fitted with the fitting protrusion 34d. ) Is molded. Therefore, in the present invention, it can be seen that the fitting protrusion 34d is coupled to the fitting 22D formed in the outer coupling groove 32b by the interference fitting, so that the adjacent flooring 10 can be connected to each other.

Here, when the first side wall 22A of the flooring 10 is engaged with the second side wall 22B of the adjacent flooring 10, the second side wall 22 of the flooring 10 adjacent to the first side wall 22A ( The head 34a is inserted into the head coupling groove 32a while slightly overlapping with 22B, and the extension fitting portion 34b is inserted into the outer coupling groove 32b. When the extension fitting portion 34b is inserted into the outer coupling groove 32b, the fitting protrusion 34d is coupled to the fitting groove 22D by an interference fit.

As shown in FIG. 7, the fitting protrusion 34d is coupled to the fitting groove 22D. It can be seen that the interference fit in the present invention is configured to occur when the fitting protrusion 34d is coupled to the fitting groove 22D. Where the fitting protrusion 34d and the fitting groove 22D are designed to be pressed together, to separate the combined flooring 10 as described above, it should be possible to separate the interference fit described above. Separating the flooring material 10 from each other substantially means that the fitting protrusion 34d can be separated from the fitting groove 22D.

As shown in FIG. 7, inclined surfaces 34da and 34dc are formed in the fitting protrusion 34d at the upper end and the lower end, respectively. The inclined surface 34da at the bottom is formed to be relatively smoother, and is formed to be smoothly guided when the fitting protrusion 34d is coupled to the outer coupling groove 32b. And when the inclined surface (34dc) in the upper portion is separated from the upper jaw (22DC) of the fitting groove (22D), it is molded to be able to ride over the upper jaw (22DC) elastically. If the inclined surface 34dc is not formed and the top surface of the fitting protrusion 34d has a horizontal surface, it may be extremely difficult to be engaged with and separated from the upper jaw 22DC of the fitting groove 22D.

In the shaping of the fitting protrusion 34d of the present invention, the upper inclined surface 34dc may be formed into an inclined surface directly at the extended fitting portion 34b like the lower inclined surface 34da. In the illustrated embodiment, it can be seen that the upper inclined surface 34dc is formed into an inclined surface after forming a vertical protrusion 34de having a predetermined size in the extension fitting portion 34b. This configuration means that it can be separated from the fitting groove 22D and the fitting protrusion 34d only when a predetermined force or more is applied thereto, and is intended to prevent arbitrary separation by a weak external force. In other words, the force required for separation of the flooring material 10 is relatively larger than the force required for bonding.

As described above, when assembling the flooring material 10 in the left and right direction in the present invention, when the extension fitting portion 34b is inserted into the outer coupling groove 32b, the fitting protrusion 34d is forced into the fitting groove 22D. It can be seen that the flooring 10 is connected in a planar manner by being fitted by being fitted. However, the constitution of connecting the flooring material 10 of the present invention to the interference fit is considered to be limited to the interference fit between the fitting groove 22D and the fitting protrusion 34d as described above.

For example, it is considered that the connection of the flooring material 10 is sufficiently possible even when the head 34a of the left and right coupling protrusions 34 is forcibly fitted to the head coupling groove 32a. In another embodiment, an interference fit may occur between the length of the extension fitting portion 34b (which corresponds to the length from the first side wall 22A to the head 34a) and the thickness of the second side wall 22B. It is also possible to design so that. Even in the case of such interference fit, it is also preferable to form projections and grooves such as the fitting protrusion 34d of the extended fitting portion 34b and the fitting groove 22D of the outer coupling groove 32b as in the case described above. It is expected.

Next, the vertical coupling of the square frame 20 of the flooring 10 will be described. When the left and right coupling of the rectangular frame 20 described above is arranged, the left and right coupling grooves 32 are formed in the first side wall 22A between the hexagonal units 12 arranged up and down, and the left and right coupling are arranged in the second side wall 22B. It can be seen that the protrusions 34 are molded to combine the two. In the present invention, in the case of using a unit having a different shape such as a square unit or a triangular unit without using a hexagonal unit, a first shape left and right coupling groove ( A large number of 32 pieces may be molded, and a first shape left and right coupling protrusion 34 having a shape corresponding to the first shape left and right coupling grooves 32 may be formed outside the second side wall 22B. .

As shown in FIG. 1, the upper and lower coupling grooves 38 and the vertical coupling protrusions 36 are also formed in the upper wall 24a and the lower wall 24b of the square frame 20 of the flooring material 10 of the present invention. The vertical coupling protrusion 36 is coupled to the vertical coupling groove 38 formed on the upper portion of the adjacent flooring 10, the flooring of the present invention can be assembled and extended in the vertical direction.

As illustrated in FIG. 3, in the present invention, the vertical coupling protrusion 36 includes an extension fitting portion 36b extending downwardly (outside) from the lower wall 24B of the rectangular frame 20, and formed at an end thereof. It consists of the head 36a. And the upper and lower coupling groove 38 is composed of a head coupling groove 38a to which the head 36a is coupled, and an outer coupling portion 38b to which the extension fitting portion 36b is coupled.

Since the upper wall 24a of the square frame 20 is a line connecting the upper vertices of the hexagonal unit 12, the head coupling is performed among the upper and lower coupling grooves 38, which are spaces formed between the left and right adjacent hexagonal units 12. The shape of the groove 38a is different from the shape of the head engaging groove 32a formed in the first side wall 22A, which will be clearly seen in FIG. Therefore, as shown in FIG. 3, the shape of the head 36a of the upper and lower engaging projections 36 of the lower wall 24b entering the head engaging groove 38a of the upper wall 24a having such a shape is the left and right engaging projections ( 34 is configured differently from the shape of the head 34a.

Thus, when the head 36a and the left and right coupling protrusions 34 of the upper and lower coupling protrusions 36 have different shapes, the directionality of the plurality of flooring materials 10 is combined. It is easy to find the correct assembly. In other words, by changing the shape of the heads 34a and 36a, substantially the operator can know the direction more easily and can be more easily assembled in each head coupling groove.

As can be seen with reference to Figure 3, in the configuration of the vertical coupling projection 36, except for the shape of the head 36a, substantially the same as the configuration and function of the left and right coupling projections (34). That is, fitting protrusions 36d are formed at both sides of the extension fitting portion 36b of the vertical coupling protrusion 36, and the fitting protrusion 36d is exactly the same as the configuration and function of the fitting protrusion 34d of the left and right coupling protrusions. will be.

And, as shown in Figure 4, the configuration of the outer coupling groove 38b to which the vertical coupling projection 36 is fitted is also the same. Fitting grooves 24D are formed at both sides of the outer coupling groove 38b, and the fitting protrusion 36d coupled to the fitting groove 24D by interference fit also has the same configuration and function as the corresponding portions of the left and right coupling protrusions. To have.

In the present invention, when the coupling structure in the vertical direction is arranged, the upper and lower coupling grooves 38 are formed on one side of the upper wall 24A or the lower wall 24B, and the upper and lower coupling protrusions 36 are formed on the other side of the flooring material in the vertical direction. It is configured to be able to combine a lot of 10). However, the head 36a of the coupling protrusion 36 in the up and down direction has a different shape from the head 34a of the coupling protrusion 34 in the left and right direction, which is substantially the head coupling groove 38a of the up and down coupling groove 38. ) Means that the shape of the head coupling groove 32a of the left and right coupling grooves 32 is different from each other.

In the illustrated embodiment, the shape of the head coupling portion 38a of the upper and lower coupling grooves 38 and the head coupling groove 32a of the left and right coupling grooves 32 is different from each other, and thus the left and right coupling portions can be coupled to different shapes. It can be seen that the shapes of the head 34a of the coupling protrusion 34 and the head 36a of the vertical coupling protrusion 36 are formed differently.

However, in order to accurately assemble the direction of the square frame 20 of the flooring material 10 in the present invention, as described above, the shape of the heads 34a and 36a may not be limited to different shapes. For example, it is also possible to ensure directionality by combining and configuring any part of the left and right coupling protrusions 34 / left and right coupling grooves 32 and the vertical coupling protrusion 36 and the vertical coupling grooves 38 to have different shapes. will be.

Specifically, for example, the shape of the extension fitting portion 34b of the left and right coupling protrusions 34 is configured differently from the extension fitting portion 36b of the vertical coupling protrusion 36, so that the assembly direction of the flooring material can be easily understood. It is also possible to configure. This configuration can be said to have substantially the same meaning as forming different shapes of the outer coupling portion 32b of the left and right coupling groove 32 and the outer coupling groove 38b of the vertical coupling groove 38.

Next will be described in detail with respect to the embodiment of the unit 12 to enter the interior of the rectangular frame 20. In the illustrated embodiment, the support unit 12 implemented in the inside of the rectangular frame 20 has a hexagon (honeycomb shape) when viewed in plan view as described above. It is well known that such a hexagonal unit 12 can provide a sufficient support strength against external force, since it can form a trust structure that is substantially structurally advantageous in the distribution of load.

Therefore, the flooring material of the present invention is formed by using the hexagonal structure, that is, honeycomb-like structure, to have a sufficient support strength by the load applied from the top to the bottom. In this case, the load applied to the flooring material may be a vertical component applied vertically, but it may be said to include all external forces such as a horizontal component such as a horizontal component by weighted horizontal component. The flooring material 10 of the present invention, which is injection-molded with synthetic resin, should have a horizontal surface to allow sports on the upper surface. On the bottom face of the flooring 10, a plurality of legs 11 extending downward are molded, for example, formed at each corner of the hexagonal unit 12. As shown in FIG.

Therefore, it can be seen that the upper surface of the hexagonal unit 12 maintains a horizontal plane at a predetermined distance from the ground by the plurality of legs 11. And a predetermined gap is formed between the hexagonal unit 12 itself and the hexagonal unit 12 arranged in series, such a gap can have a function such as draining rainwater or falling of foreign matter. And as will be described later, it is obvious that both sides and the upper and lower surfaces of the square frame forming the outer surface of the flooring 10 should have the same height as the legs described above, of course, it is possible to lose weight, depending on the needs of injection molding,

When a large number of users exercise on such a flooring material 10, substantially many kinds of loads are applied to the flooring material. As such, the load applied to the flooring 10 should be substantially supported by the internal structure of the flooring 10. In the present invention, the hexagonal unit (honeycomb shape) is basically used to induce the load to be dispersed. It is molded so as to have a strong external force as a whole, such as a trust structure.

In addition, the reinforcing bridge 16 is provided inside the hexagonal unit 12 in order to reinforce structural strength of the hexagonal unit 12 that is continuously arranged left and right and up and down. In the present invention, the reinforcing bridge 16 is molded for structural strength reinforcement in the interior of the hexagonal unit 12, and in the illustrated embodiment, extends from the three corners at equal intervals inside the hexagonal unit 12 to the inner center. They are molded to meet at one point. Therefore, the reinforcement bridge 16 extending outward with an equal interval of 120 degrees from the inner center point of the hexagonal unit and connected to the corner of the hexagonal unit is considered to be more advantageous for the dispersion of external force.

As described above, the upper surface of the flooring material 10 of the present invention is to form a flat surface, for example, to enjoy sports, the upper surface of the flooring material 10 in any case, such as sports or walking is configured to have a sufficient friction force It is preferable. In any case of sports, walking, running of any sport, because the user is a safety problem, the top surface of the flooring 10 should have a sufficient friction force.

In the present invention, as shown in the enlarged view of Figure 1, it can be seen that the friction projections 17 are formed on the upper surface of the reinforcing bridge 16 described above, when the molded along the reinforcing bridge 16 linear It is considered to be preferable to mold with. In addition, the friction protrusion may be formed on the upper surface of the hexagonal unit as well as the upper surface of the reinforcing bridge 16.

When the bottom member 10 is formed using the hexagonal unit 12 as described above, as can be seen in the enlarged view of FIG. 1, the outer surface 14 of the outermost hexagonal unit 12 has a substantially rectangular frame. It coincides with the vertical plane of 20, which is also the same on the left vertical plane of the rectangular frame 20.

Therefore, when the rectangular frame 20 is formed by arranging a plurality of hexagonal units 12 having a honeycomb structure up, down, left, and right, the left and right sides 22: 22A and 22B of the rectangular frame 20 are formed of the hexagonal unit 12. It is possible to form the same surface as the outer surface 14. This fact is that when the plurality of rectangular frames 20 are arranged substantially in the left and right directions in FIG. 1, a rectangular frame in which the hexagonal unit shape (honeycomb shape) is not damaged at least in the left and right directions can be continuously formed. This means that it will be advantageous for the dispersion of external forces and thus have sufficient advantages in terms of structural strength.

As described above, in the present invention, when the rectangular frames in which a plurality of units are arranged are arranged in left and right and up and down directions, the subject of the present invention is designed to easily recognize the directionality of the flooring material 10 and to assemble excellently. have. Within the technical scope of the present invention as well as other modifications are possible to those skilled in the art, of course, the protection scope of the present invention should be interpreted based on the appended claims.
