  By the way, in the construction of flooring material, the most problematic point in using an adhesive is that excess adhesive overflows to the upper surface side of the flooring material. Educate workers on how to apply adhesives and give instructions on the application position and amount, etc., but it is usually done at the discretion of each worker. . In many cases, a mark line or a groove provided so that the nail driving position can be understood is used, and the workability of the nail driving is improved.

  The present invention has been proposed in view of such circumstances, and its purpose is to prevent the adhesive from overflowing to the upper surface side during construction, enabling efficient construction work, and joining and It is providing the flooring which can improve fixation stability.

  In order to achieve the above object, the flooring of the present invention is provided with a ridge-shaped male part at one side end at both ends in at least one direction and a groove-shaped female at the other side end. In the floor material provided with a real part, the floor material adjacent to the floor material and the side material that can be fitted between male and female, a groove for nailing is formed on the upper surface of the lower protrusion of the female real part. The groove is formed so that the adhesive can be stored and held to the extent that the head of the nail driven into the groove is immersed, while the lower surface of the male part protrudes downwardly and is inserted into the groove. When a convex part of an adjacent flooring is inserted into the groove part, a gap is formed to store the head of the nail driven between the groove part and the inserted convex part. It is characterized by that.

  In the present invention, the side edge portion of the flooring material may have a shape in which a gap for storing an adhesive is formed when the adjacent flooring material is sexed.

  In the present invention, the bottom part of the female real part may be further formed with a concave part dug into the deep side, and when the male and female floors are fitted to the adjacent flooring, the concave part is used for storing an adhesive. It is good also as a structure which can become a space | gap.

  In the present invention, a chamfered portion may be formed in at least one of the corners of the ridge formed on the side end portion, and when the male and female floors are fitted to the adjacent flooring, It is good also as a structure which a space is formed between the side edge part of the adjacent flooring, and the space can become the space | gap for adhesive reservoirs.

  According to the flooring material of the present invention, since it has the above-described configuration, it is possible to prevent the adhesive from overflowing to the upper surface side of the flooring material during construction, and the construction work can be efficiently performed, and the bonding property and fixing can be performed. Stability can be improved.

(C) is a partial expanded longitudinal cross-sectional view which shows the middle state of the male-female fitting process of floor materials. (A)-(c) is a partial expanded longitudinal cross-sectional view which shows three examples of the flooring which concerns on other embodiment of this invention.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  A flooring 1 according to a plurality of embodiments described below is provided with a ridge-shaped male part 10 at one side end in at least one side end part in one direction, and a grooved female part at the other side end part. This is a flooring that is provided with a portion 20 so that the adjacent flooring 1 and the side ends can be fitted male and female (see FIGS. 1 to 3).

  A groove portion 21 for nailing is formed on the upper surface of the lower ridge portion 24 of the female real portion 20 of the flooring 1, and the groove portion 21 immerses the head 5a of the nail 5 driven into the groove portion 21. The shape is such that the adhesive 6 can be accumulated and held to the extent. On the other hand, a projecting portion 11 that protrudes downward and is inserted into the groove portion 21 is formed on the lower surface of the male portion 10 of the flooring 1 (see FIGS. 1 to 3 above).

  When the convex portion 11 of the floor material 1 installed adjacent to the groove portion 21 of the lower ridge portion 24 is inserted, the head 5a of the nail 5 is interposed between the groove portion 21 and the inserted convex portion 11. Are formed (see FIGS. 1 to 3).

Hereinafter, embodiments will be described individually.
1 and 2 are explanatory diagrams of a flooring according to an embodiment of the present invention.

  FIG. 1 is a longitudinal sectional view of a flooring. 2 (a) and 2 (b) are partial longitudinal sectional views showing a joining and fixing structure for flooring. FIG.2 (c) is a partial expanded longitudinal cross-sectional view which shows the middle state of the male-female fitting process of floor materials.

  The flooring 1 according to the present embodiment is made of, for example, a rectangular substrate in which a decorative material (not shown) is laminated on the surface of a wooden base material (not shown). In addition, as a wooden base material, various wooden materials, such as a plywood, MDF, and a particle board, are used. The flooring 1 can also be applied as a floor heating panel.

  The flooring 1 is provided with a ridge-shaped male solid part 10 at one side end at at least one side end in one direction, and a groove-shaped female real part 20 at the other side end. It is the structure which can carry out male-female fitting between the flooring 1 adjoined on the upper side, and side edge parts.

  The male part 10 of the flooring 1 has a plate shape extending outward so as to be parallel to the surface, and both upper and lower corners (in the thickness direction) of the tip are chamfered. On the lower surface of the male part 10, a ridge-like convex part 11 protruding in a tapered shape (inverted trapezoidal shape) downward is formed. Further, on the upper side of the base end of the male part 10, a ridge 12 protruding in a mountain shape in the same direction as the male part is formed. By the construction of the floor material 1, a design groove is formed by the upper inclined surface of the ridge 12 and the upper inclined surface of the upper ridge portion 23 on the female real part 20 side described later.

  An upper notch 13 is formed between the ridge 12 and the male part 10. Further, the length dimension from the side end of the lower notch 14 of the male part 10 is sufficiently larger than that of the upper notch 13.

  On the other hand, the upper and lower corners in the back of the female real part 20 are formed at a substantially right angle, and a concave part 22 having a square groove shape dug further into the back side is formed in the back bottom part 20a.

  Further, a lower ridge portion 24 is formed below the female real portion 20, and an upper ridge portion 23 is formed above. The projecting dimensions of the upper and lower ridge parts 23 and 34 correspond to the depth dimensions of the upper and lower cutout parts 13 and 14 of the male part 10, and the projecting dimension of the lower ridge part 24 is higher than that of the upper ridge part 23. It is larger than the protruding dimension. Further, as will be described later, when the male and female are fitted, a gap 8 is formed in the back of the lower notch portion 14, and therefore, the projecting dimension of the lower protrusion 24 is the same as that of the lower notch portion 14. It is slightly smaller than the depth dimension.

  Further, a groove portion 21 is formed on the upper surface of the lower ridge portion 24 of the female real portion 20 to indicate a nailing portion. Since the convex part 11 formed in the male part 10 of the other flooring 1 is inserted into the groove part 21 at the time of construction, the tip of the upper ridge part 23 is taken into consideration for ease of construction. It is desirable to provide it on the outer side.

  Further, the upper ridge portion 23 of the female real portion 20 has a shape in which the upper surface is an inclined surface that is lowered from the surface side, and the lower corner portion is chamfered.

  As indicated by a two-dot chain line on the female real part 20 side in FIG. 1, when the floor materials 1 and 1 are mated with each other, a plurality of gaps 7 and gaps 8 are formed. First, gaps 7 and 7 are formed on both side walls and the bottom side in the groove 21 by fitting (free fitting) between the convex portion 11 and the groove 21.

Further, by fitting the female real part 20 and the male real part 10, two gaps 8 are formed by the chamfered corners of the male real part 10, and one place is formed by the central recess 22 in the vertical direction. A void 8 is formed. The recess 22 preferably has an opening width of 0.5 to 5.0 mm and a depth of 0.1 to 5.0 mm. Furthermore, by fitting the upper ridge portion 23 and the upper notch portion 13, a gap 8 is formed by the lower corner portion of the upper ridge portion 23 that is chamfered. Also, slightly larger gap 8 is formed on the back side of the lower notch 14 by contact is, male and female mating is formed slightly more deeply than the projecting dimension of the lower notch 14 the lower ridge 24 .

  The plurality of gaps 7 and the gaps 8 as described above that are formed during male-female fitting serve as reservoirs for excess adhesive 6 applied between the side edges of the flooring 1 during construction (FIG. 1). And FIG. 2 (b)). In addition, the formation site | part of the space | gap 8 is not restricted to the thing of the example of a figure of this embodiment, Another site | part may be sufficient. Further, the number of the voids 8 is not limited. It is preferable that the chamfered portion for forming the gap 8 is formed in at least one corner portion of the protruding portion such as the male portion 10 and the upper protruding portion 23.

  Next, the male-female fitting and joining structure between the side end portions of the flooring 1 relating to the construction of the flooring 1 will be described with reference to FIGS.

  The flooring 1 is disposed on the floor base 2, and a nail 5 is struck in the groove 21 on the female real part 20 side in order to be firmly fixed to the floor base 2. The nailing is preferably performed in an oblique direction in order to obtain a predetermined fixing strength. In consideration of ease of nailing, it is desirable to nail the inner corner of the groove 21 as in the example of FIG. Note that, as shown in FIG. 2C, the nail 5 may be hit diagonally along the groove forming direction of the groove portion 21.

  After nailing the groove 21 in this way, the adhesive 6 is applied to the upper surface of the lower protrusion 24 and the inner surface of the female real part 20. It is desirable to apply the adhesive 6 evenly on the joint surface such as the inner surface of the female real part 20. In particular, as shown in FIG. 2A, it is desirable to apply the adhesive 6 so that the adhesive 6 is accumulated in the groove 21. By applying in such a manner, the head 5 a of the nail 5 that has been driven in is immersed in the adhesive 6 accumulated in the groove 21.

  And the other flooring 1 is male-female fitting with respect to the flooring 1 installed previously (refer FIG. 2 (a), (b)). When both floor materials 1 and 1 are fitted, as shown in FIG. 2C, the convex portion 11 of the floor material 1 to be installed later is inserted into the groove portion 21 of the installed floor material 1. The adhesive 6 accumulated in the groove 21 is pushed out, and the pushed-out adhesive 6 flows in the direction indicated by the white arrow. In this way, the adhesive 6 spreads in the direction that requires the adhesive 6.

  Thus, since the adhesive 6 spreads widely on the joint surface of both flooring materials 1 in the fitting process of both flooring materials 1, both flooring materials 1 are strongly joined to each other.

  As shown in FIGS. 1 and 2B, the groove portion 21 and the convex portion 11 are formed so that the lower surface of the male portion 10 is in close contact with the upper surface of the lower protrusion 24. The gap 7 is formed in the groove 21 even if it is inserted into the groove 21. The gap 7 may be of such a size that the projection 11 does not contact the head 5a of the nail 5 that has been driven in or slightly contacts. In other words, even if the head portion 5a of the nail 5 and the convex portion 11 come into contact with each other, the contact does not make it difficult to perform the joining work or distort the joining portion between the floor materials 1 and 1. Is desirable.

  As described above, since the gap 7 is formed in the groove portion 21 by joining the two flooring materials 1, it is possible to prevent a problem in joining the two flooring materials 1 and 1 by the heads 5 a of the nails 5. be able to.

  Further, since the gap 7 is formed in the groove portion 21, even when the convex portion 11 is inserted, an outflow passage for the adhesive 6 through the gap 7 is secured, and the adhesive 6 is pushed out smoothly. Further, the gap 7 can also serve as an accumulation space for excess adhesive 6.

  As described above, the gap 7 is used for the above-mentioned purpose, and further, in consideration of various ways of driving the nail 5 (see FIG. 2 (c)), as described above, the protrusion in the groove 21 is formed. It is desirable to be formed below and to the left and right of the portion 11.

  As described above, the groove portion 21 on the side of the female real part 20 has 3 functions of a nail driving convenience function (for securing the marking and easiness of the nailing operation), a feeding action of the adhesive 6 at the time of joining, and an adhesive pooling action. Exhibits the action of the seed

  When joining both flooring materials 1, in addition to the gap 7 space in the groove portion 21, the chamfered portion on the male real portion 10 side, the chamfered portion on the female real portion 20 side, and the bottom portion of the female real portion 20 are also provided. Since many voids 8, 8,... Are formed by the recesses 22, excess adhesive 6 can be stored in them. A slightly larger amount of the adhesive 6 heading downward due to gravity can be stored in the space 8 on the back side of the lower notch portion 14.

  Thus, since this flooring 1 has a shape in which a plurality of gaps 7 and gaps 8 can be formed in the joining, it is possible to prevent the excess adhesive 6 from overflowing to the surface of the flooring 1. Efficient construction can be done.

  In addition, the flooring 1 of the present embodiment has a structure in which the upper notch 13 and the upper protrusion 23 are fitted above the male part 10 and the female part 20, and is unevenly fitted in two steps, upper and lower. Therefore, the overflow of the adhesive 6 to the surface side of the flooring 1 can be more sufficiently prevented.

  As described above, according to the present flooring 1, the flooring 1 can be efficiently delivered to the joining surface of the adhesive 6 during joining and the excess adhesive 6 can be stored. Can be efficiently constructed. Moreover, since the adhesive agent 6 can be sent out to a wider range of the joining surface, it is possible to improve the joining property and fixing stability between the flooring materials 1.

  About the shape of the groove part 21 and the convex part 11, various things can be assumed. For example, what was shown in Drawing 3 (a)-(c) may be used. Note that any flooring 1 has a configuration in which the gap 7 is formed in the groove 21 by inserting the convex portion 11 into the groove 21.

  In FIG. 3A, both wall surface parts 21a and 21a of the groove part 21 formed in the lower ridge part 24 are shaped to be inclined upward. Further, both side surface portions 11 a, 11 a of the convex portion 11 formed in the male portion 10 have a shape that is recessed toward the tip corresponding to both wall surface portions 21 a, 21 a of the groove portion 21. Since it has such a shape, it is possible to easily extrude the adhesive accumulated in the groove 21.

  In FIG. 3 (b), only the wall surface portion 21a on the back side of the groove portion 21 formed in the lower ridge portion 24 and the side surface portion 11a of the convex portion 11 formed in the male portion 10 corresponding thereto are inclined shapes. It has become. Therefore, it is possible to increase the amount of the adhesive that is fed to the back of the female real part 20 (see FIG. 1) that particularly requires the adhesive. Since the adhesive is difficult to flow outward, the adhesive can be used efficiently, and waste of the adhesive can be reduced.

  The shape shown in FIG. 3C is similar to the shape shown in FIG. 3A, but has a curved shape so that the side surface portion 21a of the groove portion 21 is gently inclined toward the upper surface side. Thus, since the opening edge of the groove portion 21 is formed in a round shape, it is possible to further easily feed the adhesive upward. This curved shape may be applied only to the inner wall surface 21a.
