Description

  The present invention relates to a flooring material of a construction method that has a male part at one end and a female part at the other end and is not fixed to the ground.

  As this type of conventional flooring material, a flooring material that prevents a decrease in the aesthetic appearance of the joint and a walking feeling that occurs in response to a dimensional change due to a temperature change of the flooring material has been proposed (for example, see Patent Document 1). ). The technique of this document makes a part of the surface of the real part an inclined surface and absorbs the amount of expansion of the flooring by the inclined surface, while enabling the push-up to be suppressed. The gap created when the flooring contracts is made inconspicuous.

  Thus, the thing of the said literature does not suppress generation | occurrence | production of the gap itself. In particular, in the case of construction in which the flooring is not fixed to the base, it is almost impossible to prevent the occurrence of gaps with the above-mentioned literature.

  The joint between the male and female real parts is strengthened by eliminating the gap at the joint between the male real part and the female real part by forming the male real part and the female real part in an inclined shape or in the form of a bowl. It is conceivable to prevent the adjacent floor materials from separating from each other. By doing in this way, even if it is construction which does not fix a flooring to a groundwork, possibility that a gap will occur will become low.

Japanese Patent No. 3682441

  However, in the case of actual joining without a gap as described above, there is a possibility that a strong force acts between the floor materials due to a change in the size of the expansion and contraction of the floor materials and the actual part may be damaged. For example, a portion protruding in the thickness direction of the flooring may be damaged due to the tension between the flooring. Therefore, although play (gap) is required at the joint, rattling may occur due to the gap.

  The present invention has been proposed in view of such circumstances, and the purpose thereof is to make it difficult for gaps to form at the joint between the male part and the female part, causing rattling, and dimensional changes. It is to provide a flooring material in which the real part is not easily damaged due to factors such as.

  In order to achieve the above object, the flooring of the present invention is a flooring of a construction method that has a male part at one end and a female part at the other end and is not fixed to the ground. The male real part has a base end part and a front end part, and the lower surface of the base end part is inclined downward toward the front end side, while the female real part has an entrance part and a back part. The bottom surface of the entrance portion is inclined upward toward the distal end side, and an elastic member is disposed between the upper surface of the distal end portion of the male real portion and the ceiling surface of the rear portion of the female real portion. It is characterized by.

  In order to achieve the above object, the flooring material of the present invention is a flooring material that has a male part at one end and a female part at the other end and is not fixed to the ground.

(A)-(c) is the partially abbreviate | omitted longitudinal cross-sectional view which showed typically the aspect of joining of the flooring materials which concern on other embodiment of this invention.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 3 are partially abbreviated longitudinal sectional views schematically showing each of the three modes of joining floor materials on a base in (a) to (c).

  The flooring 1 shown in FIG. 1 is a construction-type flooring that has a male part 11 at one end and a female part 14 at the other end and is not fixed to the base 3. The male part 11 has a proximal end part 12 and a distal end part 13, and the lower surface 12b of the proximal end part 12 is inclined downward toward the distal end side. On the other hand, the female real part 14 has the entrance part 15 and the back part 16, and the bottom face 15a of the entrance part 15 inclines upward toward the front end side. Further, an elastic member 20 is arranged between the upper surface 13 a of the distal end portion 13 of the male real part 11 and the ceiling surface 16 b of the rear part 16 of the female real part 14.

  The flooring 1 is composed of a flooring main body 10 and an elastic member 20. The flooring main body 10 has a configuration in which a surface decorative material 10b is laminated on the surface of a base material 10a. As the base material 10a, various materials such as a wood material and a synthetic resin material can be used. For example, the base material 10a may be formed of a wooden board such as a particle board or a wooden board such as a wooden fiber board. Further, as the surface decorative material 10b, a veneer single plate, a synthetic resin sheet, or the like can be used.

  The flooring main body 10 has a male solid part 11 at one end of at least one side end in one direction, and has a female groove part 14 having a concave groove shape at the other end. The flooring 1 is installed on the base 3 by joining the male and female real parts in relation to the adjacent flooring 1. A fixing member such as an adhesive or a nail is not used for installing the flooring 1 on the base 3.

  In the male part 11, the lower surface 12b of the base end portion 12 is inclined downward toward the distal end side, and the upper surface 12a is also inclined downward, and the entire shape of the proximal end portion 12 is inclined downward toward the distal end side. It has a shape. Further, the front end 13 of the male part 12 has a shape parallel to the back surface of the flooring main body 10. That is, the male part 11 has a bent shape with an obtuse angle on the surface side of the base end part 12 and the tip end part 13.

  On the other hand, in the female real part 14, the bottom surface 15a of the entrance part 15 of the concave groove is inclined upward toward the front end side, and the ceiling surface 15b is also inclined upward, so that the entire entrance part 15 is directed toward the front end side. It has an upward slope shape. Further, the rear portion 16 of the female real portion 14 has a shape parallel to the back surface of the floor material body 10. That is, the female real part 14 has a bent shape with an obtuse angle on the surface side of the back part 16 and the entrance part 15.

  Thus, both the male part 11 and the female part 14 have a bent shape with an obtuse angle on the front side, and the male part is considered in consideration of the ease of joining between the flooring materials 1 and 1. The vertical dimension of the female real part 14 is larger than the thickness dimension of the part 11. In particular, the entrance 15 of the female real part 14 opens sufficiently wide, and when the male real part 11 of the new flooring 1 is joined to the female real part 14 of the existing flooring 1, it becomes easy to insert and mount. ing.

  The inclination of the upper surface 12a of the base end part 12 of the male real part 11 and the inclination angle of the ceiling surface 15b of the entrance part 15 of the female real part 14 are substantially the same. Moreover, the front end of the upper ridge 17 of the female real part 14 is cut off in an inclined manner. Because of this shape, when both flooring materials 1 and 1 are joined as shown in FIG. 1 (b), a gap is formed downward at the joint 5 between the male part 11 and the female part 14. A joint groove 19 that does not communicate with the space is formed on the surface.

  Furthermore, the elastic member 20 is affixed to the upper surface 13a of the front-end | tip part 13 of the male real part 11, as shown in FIG. As this elastic member 20, a flexible synthetic resin such as urethane resin, rubber, or the like is used. In a state in which the elastic member 20 is arranged at the distal end portion 13 of the male real part 11, the overall thickness dimension is larger than the vertical dimension of the rear part 16 of the female real part 14.

  When joining the newly installed flooring 1 to the existing flooring 1, the elastic member 20 disposed on the male part 11 of the new flooring 1 is used as the female part 14 of the existing flooring 1 as shown in FIG. By being pressed against the ceiling surface 16b of the back portion 16 of the inner wall 16 and being compressed, actual joining can be smoothly performed. As shown in FIG. 1B, the elastic member 20 is compressed in the vertical direction in the actual joined state, and the urging force of the elastic member 20 acts to lower the lower surface 13 a of the distal end portion 13 of the male real part 11. Is in contact with and pressed against the bottom surface 16a of the back portion 16 of the female real part 14.

  Thus, the male part 11 of the new flooring 1 is securely attached to the female part 14 of the existing flooring 1. At least, in the relationship between the distal end 13 of the male real part 11 and the rear part 16 of the female real part 14, no gap is generated between the upper and lower sides due to the action of the elastic member 20. Therefore, rattling is unlikely to occur in the construction state. In addition, since the tip 13 of the male part 11 presses the bottom surface 16a of the rear part 16 of the female part 14 by the elastic member 20, the floor materials 1 and 1 are also displaced in the direction away from each other. Hateful.

  Further, when a dimensional change occurs in the flooring main body 10 at the time of drying or the like, both the flooring materials 1 and 1 are contracted and try to be separated from each other. At this time, as shown in FIG. 1C, the distal end portion 12 of the male real part 11 tries to ride on the bottom surface 15a of the entrance 15 of the female real part 14, and at the same time, the elastic member 20 is further compressed. That is, in this state, as shown in FIG. 2 (c), the joint portion 5 has an appropriate gap space with the elastic member 20, so that a large load is not applied to both real portions. Both floor materials 1, 1 try to separate.

  Thus, even if both the flooring materials 1 and 1 are bent in shape, they are separated smoothly and smoothly by the gap between them and the elastic member 20 disposed in the gap. The upper and lower ridges 17 and 18 on the real part 14 side are hardly damaged. Further, in the state of FIG. 1C, the male part 11 presses the female part 14 by the elastic member 20, so that both flooring materials 1 and 1 can be held in the state of FIG. 1C. Therefore, rattling is unlikely to occur in this state.

  Further, if the floor materials 1 and 1 are separated from each other, a gap 7 as shown in FIG. 1C is generated. As described above, the upper surface 12a of the base end portion 12 of the male real part 11 and the female real part Since the ceiling surface 15b of the 14 entrance portions 15 is an inclined surface, the gap leading downward from the joint groove 19 can be made shallow.

  In this embodiment, the elastic member 20 is attached to the upper surface 13a of the distal end portion 13 of the male real part 11. However, the elastic member 20 may be applied to the ceiling surface 16b of the rear part 16 of the female real part 14. Good. In this case, if the newly installed flooring 1 is sufficiently inclined during installation and inserted from the upper surface corner of the tip 13 of the male part 11, it can be joined without any problem. In addition, after loosely fitting the male real part 11 to which the elastic member 20 is not attached to the female real part 14, the elastic member 20 is inserted between the upper and lower gaps between the male real part 11 and the female real part 14 from the surface side. You may make it make it.

  Next, the flooring 1 shown in FIGS. 2 and 3 will be described. These flooring materials 1 are flooring materials that are not fixed to the base 3 and have a male part 11 at one end and a female part 14 at the other end. The male part 11 has a proximal end part 12 and a distal end part 13, and the lower surface 12b of the proximal end part 12 is inclined downward toward the distal end side. On the other hand, the female real part 14 has the entrance part 15 and the back part 16, and the bottom face 15a of the entrance part 15 inclines upward toward the front end side. An elastic member 20 is arranged between the lower surface 12 b of the base end portion 12 of the male real part 11 and the bottom surface 15 a of the entrance 15 of the female real part 14.

  Each of these flooring materials 1 includes a flooring body 10 and an elastic member 20. The flooring main body 10 has a configuration in which a surface decorative material 10b is laminated on the surface of a base material 10a. The base material 10a and the surface decorative material 10b are the same as those shown in FIG.

  Further, the shape of the flooring main body 10 is the same as that of FIG. 1, and the male real part 11 has a bent shape and the female real part 14 has a bent groove shape. Also about these, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  Next, the flooring 1 of FIG. 2 and the flooring 1 of FIG. 3 will be described individually.

  In the embodiment illustrated in FIG. 2, the elastic member 20 is attached to the lower surface 12 b of the base end portion 12 of the male real part 11. The elastic member 20 is made of the same material as that shown in FIG.

  When joining the newly installed flooring 1 to the existing flooring 1, the elastic member 20 disposed on the male part 11 of the new flooring 1 is used as the female part 14 of the existing flooring 1 as shown in FIG. By actually pressing and compressing the bottom surface 15a of the inlet portion 15, the actual joining can be smoothly performed. As shown in FIG. 2B, the elastic member 20 is in a compressed state in the actual joined state, and the urging force of the elastic member 20 acts, so that the upper surface 12a of the base end portion 12 of the male real part 11 is female. It will be in the state which contacted and pressed the ceiling surface 15b of the entrance part 15 of the real part 14. FIG.

  Thus, the male part 11 of the new flooring 1 is securely attached to the female part 14 of the existing flooring 1. At least in the relationship between the base end portion 12 of the male real part 11 and the entrance 15 of the female real part 14, no gap is generated between the upper and lower sides due to the action of the elastic member 20. Therefore, rattling is unlikely to occur in the construction state. Moreover, since the base end part 12 of the male part 11 has pressed the ceiling surface 15b of the entrance part 15 of the female part 14 by the elastic member 20, the floor materials 1 and 1 are also displaced in the direction away from each other. Hard to occur.

  Further, when a dimensional change occurs in the flooring main body 10 at the time of drying or the like, both the flooring materials 1 and 1 are contracted and try to be separated from each other. At this time, since the elastic member 20 is interposed as shown in FIG. 2C, the elastic member 20 is further compressed. That is, in this state, as shown in FIG. 2C, an appropriate gap space is formed in the joint portion 5 between the male real part 11 and the female real part 14 with the elastic member 20. Both floor parts 1 and 1 try to separate, without applying a big load to both real parts.

  Thus, even if both the flooring materials 1 and 1 are bent in shape, they are separated smoothly and smoothly by the gap between them and the elastic member 20 disposed in the gap. The upper and lower ridges 17 and 18 on the real part 14 side are hardly damaged. Further, in the state of FIG. 2C, the male member 11 presses the upper ridge 17 of the female member 14 by the elastic member 20, so that the floor materials 1, 1 are held in the state of FIG. Can be done. Therefore, rattling is unlikely to occur in this state.

  In addition, since the male part 11 tends to move upward in this way, the gap between the upper surface 12a of the base end part 12 of the male part 11 and the ceiling surface 15b of the entrance part 15 of the female part 14 (gap 7). ) Becomes smaller. Therefore, the aesthetic appearance is hardly impaired by the gap 7.

  On the other hand, in the embodiment illustrated in FIG. 3, the elastic member 20 is attached to the bottom surface 15 a of the entrance 15 of the female real part 14. The elastic member 20 is made of the same material and the same shape as those shown in FIG.

  When the new flooring 1 is joined to the existing flooring 1, the lower surface 12b of the base end 12 of the male part 11 of the new flooring 1 is connected to the female floor of the existing flooring 1 as shown in FIG. By actually pressing the elastic member 20 against the elastic member 20 of the portion 14 and compressing the elastic member 20, the actual bonding can be smoothly performed. As shown in FIG. 3B, the elastic member 20 is in a compressed state in the actual joined state, and the urging force of the elastic member 20 acts so that the upper surface of the base end portion 12 of the male real part 11 is the female real. It will be in the state which contacted and pressed the ceiling surface 15b of the entrance part 15 of the part 14. FIG.

  Thus, the male part 11 of the new flooring 1 is securely attached to the female part 14 of the existing flooring 1. At least in the relationship between the base end portion 12 of the male real part 11 and the entrance 15 of the female real part 14, no gap is generated between the upper and lower sides due to the action of the elastic member 20. Therefore, rattling is unlikely to occur in the construction state. Moreover, since the base end part 12 of the male real part 11 is in the state which pressed the upper side protrusion 17 of the entrance part 15 of the female real part 14 with the elastic member 20, both flooring materials 1 and 1 to the separation | separation direction from each other. Misalignment hardly occurs.

  Further, when a dimensional change occurs in the flooring main body 10 at the time of drying or the like, both the flooring materials 1 and 1 are contracted and try to be separated from each other. At this time, since the elastic member 20 is interposed as shown in FIG. 3C, the elastic member 20 is further compressed. That is, in this state, as shown in FIG. 3C, the joint portion 5 has an appropriate gap space with the elastic member 20, so that a large load is not applied to both real portions. Both floor materials 1, 1 try to separate.

  Thus, even if both the flooring materials 1 and 1 are bent in shape, they are separated smoothly and smoothly by the gap between them and the elastic member 20 disposed in the gap. The upper and lower ridges 17 and 18 on the real part 14 side are hardly damaged. Further, in the state of FIG. 3C, the male member 11 presses the upper protrusion 17 of the female member 14 by the elastic member 20, so that both flooring materials 1 and 1 are held in the state of FIG. 3C. Can be done. Therefore, rattling is unlikely to occur in this state.

  In addition, since the male part 11 tends to move upward in this way, the gap between the upper surface 12a of the base end part 12 of the male part 11 and the ceiling surface 15b of the entrance part 15 of the female part 14 (gap 7). ) Becomes smaller. Therefore, the aesthetic appearance is hardly impaired by the gap 7.

  As described above, the elastic member 20 is attached to the male real part 11 in FIG. 2, and the elastic member 20 is attached to the female real part 14 in FIG. Not only these but the elastic member 20 is inserted between the opposing surfaces of the base end part 12 of the male real part 11 and the entrance part 15 of the female real part 14 in the mounting process of the male real part 11 to the female real part 14. You may do it.
