Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a joined floor, and more particularly to a joined floor having a double snap effect. [Prior Art] For the purpose of interior decoration, etc., laminate flooring of wood or other materials will be used on some concrete floors or magnetic monument floors. The conventional floor is generally horizontal and connected during construction. The floor is parallel to the ground. If you need to use a hammer or other tool to hit the floor, it is easy to hit the ground, which is not convenient for the user to construct: The joint-type floor of the People's Republic of China Invention No. CN 1195386a, cn 1422356A' and the utility model bulletin No. CN 28〇ΐ95ιγ and the US Patent No. 426820 are available, and the jointed floor & (4) The fate of the tongue is formed - the convex tongue: a concave _ 'the shape of the tongue corresponds to the groove portion, so that the plate body can be inside the groove portion of the same structural plate body, thereby making a plurality of On the board body, and 兀^, the user can quickly combine the annihilation and lay on the ground. However, another tool such as an iron key is used to strike the nail to combine the plurality of boards. The fitting into the chimeric Lai ^ ^ ^ about the insertion of the effect, in other words, the structure of the plate has only a single buckle of the buckle buckle to the handsome; inside ^_ the lower part of the tongue convex or lower f, but the corresponding concave or curved surface of the groove is only a horizontal section or other does not have a clamping effect. 4 201247978: The horizontal groove of the tongue is horizontally opposed to the tongue. The area is limited, and the horizontal tensile strength of the joint between the eight-plate body and the plate body is not ideal. In the long-term stepping on the hook of the H and the buckle of the groove part (4), the grinding is laid to cause the plate body to be pneumatic. 4 to separate from each other, and greatly shorten the service life of the joined plate. There is a problem with the above-mentioned conventional structure. Therefore, this U-grain, as described in detail below, has a progressive double-click floor. SUMMARY OF THE INVENTION The main object of the present invention is to provide a joint floor which has a double one and can closely join the two floors, and effectively resists the force of pulling the left and right sides of the two floor joints to increase the joint of the floor. Stability and structural strength of its combination. To achieve the above primary or other objects, the present invention provides a dual snap floor comprising a body. The plate body has a top surface, a bottom surface, a first surface, and a second side surface opposite to the first side surface, and a Δ joint is formed on the first side surface to form a female connector on the second side surface. The female connector is coupled to the A joint of the other plate body, and the second side has an upper abutting surface and a lower abutting top female joint is located between the upper abutting surface and the lower abutting surface, The lower abutting surface protrudes from the upper abutting surface. /, the male connector is raised from the first side, the shape of the male connector is a pair of the female connector, the female connector is from the second side of the concave body, the female connector includes a - horizontal plane, - the first a curved surface and a second curved surface, one end of the horizontal plane 5 201247978 is connected to the lower end, and the other end of the horizontal plane is connected to one end of the first curved surface 'the other end of the first curved surface Attached to the end of the second curved surface, and the other end of the second curved surface is in contact with the upper abutting surface, the first arc mask has a lowest point, the lowest point Wei_the arc Where the water-free plane meets, and the arcuate surface has the most return point, the southernmost point is higher than the second arc surface and the upper abutting surface; and the upper abutting surface and The length of the joint of the second curved surface from the joint of the horizontal plane and the first arc surface is A, and the length of the joint of the upper abutting surface and the second curved surface is the distance from each point of the first arc surface. The second arc has a radius of curvature of R and satisfies the following relationship: A^B; B$2R. Therefore, the two side surfaces of the double buckle floor of the present invention are respectively formed by two curved surfaces, so that the board body is relatively quick and smooth during the plugging process, and the first curved surface and the second curved surface can be respectively buckled. The male joint corresponds to the upper and lower convex arc portion, and achieves the double buckle effect, and can greatly improve the horizontal tensile strength of the joint of the two plate bodies, thereby achieving the effect superior to the conventional structure without increasing the manufacturing time. The cost is quite cost effective. [Embodiment] The technical features of the present invention and the intended effects thereof will be described below by way of a preferred embodiment, and are not intended to limit the scope of the invention as claimed. Please refer to FIG. 1 for a perspective view of a first preferred embodiment of the present invention.本实6 201247978 The double snap floor of the embodiment is mainly for laying on a floor, and comprises a plate body, a foam layer 2 and a pressure sensitive adhesive layer 3. The plate body has a top surface u ′ a bottom surface 12 , a first side surface 13 , and a second side surface μ opposite to the first side surface. The first side surface 13 defines a male connector 4 formed on the second side surface 14 . There is a female connector 5 for fitting the male connector 4' of the other plate body, and the second side surface 14 has an upper abutting surface 141 and a lower abutting surface 142, and the female connector 5 is located therein. Between the top abutting surface 141 and the lower abutting surface 142, the lower abutting surface 142 protrudes from the upper abutting surface mi. Referring further to Figure 2, the male connector 4 is raised from the first side 13 and extends substantially the entire length of the first side 13. The male connector 4 is shaped to correspond to the contour of the female connector 5. The female connector 5 is recessed from the second side surface 14. The surface joint 5 includes a first horizontal surface 52 and a second curved surface 53. One end of the horizontal surface 51 and the lower abutting surface 142 In addition, the other end of the horizontal surface 51 is in contact with one end of the first arc surface 52, and the other end of the first curved surface is connected to one end of the second curved surface 53, and the second curved surface The other end of the 53 is in contact with the upper abutting surface 141. In addition, the first orphan plane 52 has a lowest point cut, the lowest point 52H is lower than the first curved surface 52 and the horizontal plane η, and the second arc mask has a highest point s3i, the highest The point system is higher than the second arc surface 53 where there is no contact (4). Wherein the upper abutting surface (4) and the second curved surface 53 are joined to each other from the horizontal plane 51 and the first curved surface = the length of the joint is A' and the upper abutting surface 141 and the second curved surface are connected to each other. The distance from each point on the first arc surface is the curvature of the B m plane. The radius of the 2012 surface is 7 and the diameter is R, and the following relationship is satisfied: A^B; B22R. Please refer to FIG. 3 to FIG. 5 next. With the above structure, the upper and lower flanges of the male joint 4 can directly align the male and female joints of the female joint 5 with the first arcuate surface 52 and the 1_53 ^ two adjacent joints, as shown in the figure. 3 is shown. And the other-plate body male connector 4 is incorporated into the female connector 5, since the lowest point 521 of the first curved surface 52 is lower than the intersection of the horizontal surface 51 and the first curved surface 52, a male connector 4, the lower flange is buckled in the first curved surface 52; and a highest point 531 of the second curved surface 53 is higher than a junction of the upper abutting surface 141 and the second curved surface 53 The upper flange of the male connector 4 is simultaneously buckled in the second curved surface 53. Therefore, the first and second curved surfaces 52, 53 are double-folded on the lower two portions of the male joint 4', so that the The horizontal force of the male chest 4 is increased, and the horizontal tensile strength of the male and female joint reductions is greatly increased. In addition, the horizontal plane 51 connected between the lower abutting surface 142 and the first arcuate surface 52 is attached to the female head 5; in other words, the first sub-substituting top Z is spaced apart by a horizontal length of a predetermined length. The portion of the first arc surface # near the horizontal plane can strongly support the male joint 4 and the lower flange to prevent the first curved surface from being pulled by the horizontal pulling force, and the structure can be effectively prevented. When it comes to the top surface 142, it will wear out due to the force. Furthermore, in order to make the assembly process smoother and smoother, an arc-shaped chamfer 143 may be formed at the intersection of the second curved surface 53 and the upper abutting surface 141, as shown in FIG. 8 201247978 and preferably the profile of the mother _ 5 is slightly larger than the shape of the male connector 4, so that the male connector 4 is fitted to the mother lie 5, and there is a gap between the calls. 'As shown in Figure 4. Thereby, the two-phase assembled plate body has a certain margin space at the joint of the male and female joints, so that the plate body can still be flattened when the temperature of the plate body is caused by thermal expansion and contraction of the plate material. They are connected to each other, and the joints of the plates are not too tight due to the expansion of the south plate body, which causes the unevenness of the floor to be laid; or the shrinkage of the plate due to the temperature is too low. The joints of the plates are loose and not tight, resulting in the ground surface of the plate being too large and having an abnormal sound when pedaling. In addition, the foam layer 2 is completely covered on the bottom surface 12, and the pressure sensitive adhesive layer 3 is disposed under the foam layer 2 and adjacent to the lower abutting surface 142, and the area of the pressure sensitive adhesive layer 3 Less than 4% of the total area of the bottom surface. Preferably, the pressure sensitive adhesive layer 3 is arranged in a strip shape on the bottom surface 12, and the long side of the pressure sensitive adhesive layer 3 abuts against the lower abutting surface 142. Thereby, at the time of assembly (as shown in FIG. 3), the foam layer 2 can be first turned over with the ground and the male and female _ fully buckled, and the pressure layer 3 can be placed on the ground. On, and then achieve the adhesion effect, as shown in Figure *. In addition, the adhesive layer 3 is preferably provided with a release film under the bottom surface (not shown). When the plate is laid on the ground, the release film is peeled off from the bottom surface of the pressure-sensitive layer 3 'This can be avoided by sticking to the ground or sticking to the ground. However, the other possible #_ towel of the present invention may be provided without the adhesive layer 3 and only the ship 2 may be provided, or the brewing 2 and the gelatin layer 3 may not be provided. 201247978 Two embodiments. this
