Description

  The present invention relates to a resin mat that is laid on a floor to form a floor surface and that can be connected to each other.

  In recent years, resin mats of this type can be used for balconies, verandas, terraces, and the like of houses because a floor surface can be formed by simple construction of laying the mats on the floor. In such a resin mat, conventionally, a large number of through-holes penetrating from the mat surface to the back surface have been provided in order to guide water such as rainwater dropped on the mat surface forming the floor surface to the floor on which the mat is installed ( For example, see Patent Document 1).

Japanese Utility Model Publication No. 7-10191

  However, in the resin mat proposed in the above publication, since a large number of through-holes are formed with almost no gap, the strength against warpage was not sufficient. In particular, since the above-mentioned resin mat is installed in a place where a change in environment such as temperature and humidity is large, such as a balcony, a veranda, or a terrace, there is a high possibility that warpage will occur after the installation.

  On the other hand, in order to ensure the strength against warpage, it is possible to adopt a configuration in which the above-mentioned through-hole is not provided, but not only the drainage function from the mat surface to the floor is lost, but also the through-hole portion is changed to a resin portion. This makes it difficult to cut the mat, causing another problem that the simplicity of construction is lost, and is not realistic.

  Therefore, the present invention employs the following configuration for the purpose of solving the above-described problems and realizing good drainage while ensuring strength against warpage of the resin mat.

The resin mat of the present invention,
A plurality of resin mats are laid on the floor to form a floor surface, and are mutually connectable resin mats,
On the side to be the floor surface, a concave stripe extending in a concave shape,
A ridge that is located side by side with the concave ridge and forms a mat surface on the floor side;
The gist of the present invention is that the bottom of the concave stripe has an inclination in at least one direction of the mat.

  In the resin mat of the above configuration, water that has fallen on the mat surface, specifically water that has flowed down from the top surface of the ridge to the valley or water that has fallen directly into the valley, is guided to the outside of the mat by the inclination of the bottom of the valley. Is done. For this reason, it is not necessary to form through holes for water passage to the floor at many places on the mat as in the related art. Therefore, good drainage can be realized while securing strength against warpage.

  The configuration may be such that the concave stripes are formed in multiple rows. By doing so, when cutting the resin mat according to the floor area of the installation location, the cutting work of the mat is facilitated by cutting along the concave stripes. This is because the portion where the concave streak is formed is thinner than other portions.

  The resin mat described above may be configured to be connectable not only to resin mats but also to other mats. As such another mat, for example, a building material mat obtained by mounting a building material on a resin mat can be considered. Such a building material mat is obtained by fixing a building material such as tile, wood, stone, concrete material, etc. to a resin mat. Since these building materials have designs and properties unique to building materials, their use can be expanded not only to balconies and verandas. For example, the resin mat and the building material mat of the present invention may be used on passages such as a passage corridor where wood is required, or on a floor of an outdoor facility where the material is required to be stone or concrete from the viewpoint of durability and weather resistance. Can be laid in combination.

  It is also preferable to provide a gap forming means for forming a gap between the mat and the mat to be connected, from the viewpoint of increasing drainage efficiency to the outside of the mat.

  It is also preferable to provide a plurality of openings in a wall surface extending from the surface forming the floor surface to the side laid on the floor. In this way, it is possible to escape the wind blown into the laid resin mat from the opening, and it is possible to suppress the resin mat from rolling up. Further, since the aperture is provided in the wall surface, the strength against warpage is not impaired.

  Also, with respect to the convex ridges arranged in parallel with the concave ridges, the convex ridges may be provided with irregularities repeatedly on the upper surface. In this case, the anti-slip effect can be exhibited by repeating the unevenness. Then, the irregularities can be formed as a top surface concave streak and a top surface convex streak on the convex top surface of the convex streak, and further, the bottoms of these top surface concave streaks are inclined in at least one direction of the mat. Or a slope having a slope toward the side of the concave line aligned with the convex line. In this way, the water that has fallen on the top surface of the ridge can be guided to the outside of the mat by the concave top surface, or can be dropped into the adjacent ridge and guided to the outside of the mat by the concave groove. Therefore, drainage can be further improved.

  When the concave and convex ridges on the top surface are repeatedly provided in this manner, they may be linearly formed, or may be arranged in a zigzag shape. In addition, on the surface where the ridges are arranged and the top surfaces are arranged, the top surface concave and convex stripes may be concentrically repeated.

  Hereinafter, embodiments of the present invention will be described based on examples. FIG. 1 is an explanatory diagram showing the front and back surfaces of the resin mat 20 of the present embodiment. The resin mat 20 of this embodiment is a member laid on a floor such as a balcony. When laying on such a floor, resin mats 20 and tile mats 10 to be described later are prepared by the number corresponding to the area of the floor to be laid, and the resin mats 20 or the resin mats 20 and the tile mats 10 are prepared. And place them on the floor. Thereby, a decorative floor surface can be easily formed on a balcony or the like.

  1A and 1B show a front surface (hereinafter, referred to as a front surface) 20A and a rear surface (hereinafter, referred to as a rear surface) 20B of the resin mat 20, respectively. The back surface 20B is a surface that is laid on the floor such as a balcony, and the front surface 20A is a surface that is made a floor surface by laying on the floor. FIG. 1C shows a cross-sectional shape taken along line 1C-1C in FIG. 1A.

  As shown, the front surface 20A and the back surface 20B of the resin mat 20 have a rectangular outer shape. In this embodiment, the long side and the short side of the rectangle are 296 mm and 146 mm, respectively. The resin mat 20 has a predetermined thickness (28 mm in this embodiment) (see FIG. 5). Due to the presence of such a thickness, short side surfaces 20C and 20D and long side surfaces 20E and 20F are formed on the outer periphery between the front surface 20A and the back surface 20B of the resin mat 20.

  Protrusions 27 for forming a gap are provided on the side surfaces 20C to 20F. Three convex portions 27 are provided at equal intervals on each of the short side surfaces 20C and 20D, and six convex portions 27 are provided at equal intervals on each of the long side surfaces 20E and 20F. From the outside by 2 mm. In the present embodiment, the projection 27 corresponds to a “gap forming unit” in the claims.

  As shown in FIG. 1A, a concave streak 40 is formed on the surface 20A. The concave streak 40 has a shape in which the surface 20A of the resin mat 20 is cut in a groove shape from the side surface 20C to the side surface 20D in a direction parallel to the side surfaces 20E and 20F. For this reason, in the side surface 20C and the side surface 20D, the resin thickness d2 of the portion where the concave streak 40 is formed is smaller than the resin thickness d1 of the portion where the concave streak 40 is not formed (see FIG. 5A). reference).

  In the resin mat 20 of the present embodiment, eight rows of concave stripes 40 are formed parallel to each other. Due to the formation of the ridges 40, the ridges 50 are alternately arranged alongside the ridges 40. That is, the surface 20 </ b> A is divided into nine at the mounting surface 25, which is the top surface of the ridge 50. In a state where the resin mat 20 is laid, the sole of the foot is in contact with the mounting surface 25 of the surface 20A. Thereby, the mounting surface 25 functions as a substantial floor surface. In the present embodiment, each of the nine mounting surfaces 25 corresponds to a “surface forming a floor surface” in the claims.

  As shown in FIG. 1B, on the back surface 20 </ b> B of the resin mat 20, there are provided 42 legs 31 erected from the back side of each mounting surface 25. Each leg 31 is provided in a good balance over the entire range of the back surface 20B. Each leg 31 comes into contact with the floor when the resin mat 20 is laid. Thereby, the bending of the resin mat 20 due to the load from the surface 20A is prevented.

  On the back surface 20B of the resin mat 20, a connection hook 32 is provided at an end of the side surface 20C, 20E, and a connection arm 33 is provided at an end of the side surface 20D, 20F. The connecting hook 32 and the connecting arm 33 are formed integrally with each of the side surfaces 20C to 20F, and are provided at positions corresponding to the respective convex portions 27.

  FIG. 2 is an explanatory view showing a state around the connecting arm 33 of the resin mat 20 by taking the side surface 20D as an example. 2, the illustration of the legs 31 and the connection hooks 32 is omitted for convenience of explanation. As shown in FIG. 2, the connection arm 33 is provided immediately below the convex portion 27 and protrudes outside the side surface 20 </ b> D from the convex portion 27. An insertion hole 34 large enough to insert the connection hook 32 is formed in the protruding portion. By inserting the connecting hooks 32 of the resin mat 20 into the insertion holes 34 of the other resin mats 20, the resin mats 20 are connected to each other.

  Next, the configuration of the tile mat 10 will be described with reference to FIG. FIG. 3 is an explanatory diagram showing a front surface (hereinafter, referred to as a front surface) 10A of the tile mat 10. As shown in the figure, a tile mat 10 has nine 100-square tiles (95 mm × 95 mm) 11 (3 rows, 3 rows) bonded to an upper surface of a square resin mat 12 with an adhesive. It was done. In this embodiment, one side of the mat 12 has a length of 296 mm, and the tiles 11 are bonded to the mat 12 while keeping an interval of 4 mm between the tiles 11. A hole 13 (indicated by an X mark in FIG. 3) penetrating the mat 12 is formed in a portion where the intervals between the tiles 11 are set (hereinafter, referred to as joints). The water that has fallen on the surface of the tile mat 10 is guided through the holes 13 to the floor on which the tile mat 10 is laid.

  The tile mat 10 is configured to have substantially the same thickness as the resin mat 20, the tile 11 has a thickness of about 10 mm, and the mat 12 has a thickness of about 18mm. Due to the presence of such a thickness, four side surfaces 12C to 12F are formed on the outer periphery between the front surface 12A and the back surface 12B of the mat 12.

  Protrusions 17 for gap formation are provided on each of the side surfaces 12C to 12F. A connection hook 62 is provided on the side surfaces 12C and F, and a connection arm 63 with an insertion hole 64 is provided on the side surfaces 12D and E. The protrusions 17, the connection hooks 62, and the connection arms 63 are provided in the same shape or the same pitch as the protrusions 27, the connection hooks 32, and the connection arms 33 of the resin mat 20, respectively. Thereby, the connection between the tile mats 10 and the connection between the tile mat 10 and the resin mat 20 become possible.

  FIG. 4 is an explanatory diagram showing an example of laying the tile mat 10 and the resin mat 20 on a balcony floor. FIG. 4A illustrates a case where four tile mats 10 and two resin mats 20 are combined and laid on a floor FL having a predetermined area. In this case, it is necessary to cut the resin mat 20 in order to fit the total of six mats 10 and 20 within the area of the floor FL.

  In this embodiment, when cutting the resin mat 20, in principle, the resin mat 20 is cut with a cutting tool such as a cutter knife along any one of the recesses 40 in eight rows. Therefore, in the case of FIG. 4A, the cutting is performed along the concave line 40 located on the line tt (the concave line 40 closest to the outer periphery of the floor FL). By cutting in this manner, the cutting blade of the cutting tool is smoothly guided from the side surface 20C to the side surface 20D. In the case of FIG. 4A, the connecting arm 63 and the connecting arm 33 (marked in FIG. 4A) located outside the area range of the floor FL are also cut by the cutting tool. become.

  FIGS. 4B and 4C are enlarged views of the region 4B and the region 4C in FIG. 4A, respectively. As shown in FIG. 4B, in the two resin mats 20 connected on the short side, the protrusions 27 of each mat are in contact with each other at the connection portion. Thus, a clearance M1 having a width of 4 mm is formed between the side surface 20C and the side surface 20D. In addition, as shown in FIG. 4C, the convex portion 27 provided on the side surface 20C is in contact with the wall KB rising up substantially vertically from the floor FL. Thereby, a clearance M2 having a width of 2 mm is formed between the wall body KB and the side surface 20C.

  Next, the shape of the concave streak 40 will be specifically described. FIG. 5 is an explanatory diagram showing the side surfaces 20C and 20E of the resin mat 20. FIGS. 5A and 5B show the resin mat 20 shown in FIG. 1 when viewed from the directions of arrows 5A and 5B, respectively. As shown in FIG. 5A, the recess in the concave streak 40 is formed by a bottom wall 43 and a pair of inner wall surfaces 41 and 42 facing each other.

  The shape of the bottom wall 43 will be described. FIG. 5A shows a vertical cross-sectional shape of the bottom wall 43 in the short side direction (the bottom wall 43 when the resin mat 20 is cut from the front surface 20A toward the back surface 20B along a line parallel to the short side). Cross-sectional shape). As shown in FIG. 5A, the vertical cross-sectional shape of the bottom wall 43 in the short side direction is a substantially V-shaped valley shape over the entire range of the concave streak 40. The portion that becomes the valley of the bottom wall 43 is hereinafter referred to as a valley portion 43a.

  FIG. 5B shows a vertical cross-sectional shape of the bottom wall 43 in the long side direction (the bottom wall 43 of the concave streak 40 is moved from the front surface 20A to the back surface 20B along a line parallel to the long side of the resin mat 20). The cross-sectional shape of the bottom wall 43 when cut by cutting is shown by a chain line. As can be seen from the longitudinal cross-sectional shape in the long side direction, the height of the bottom wall 43 in the concave streak 40 is the highest at the point M at the center. The bottom wall 43 is provided with a downward inclination from the point M to the short side surface 20C and a downward inclination from the point M to the other short side surface 20D.

  Since the bottom wall 43 is inclined as described above, the water that has fallen into the concave streak 40 is guided by the inclination of the bottom wall 43 and smoothly guided in the direction of the side surface 20C or the side surface 20D. It is discharged out of the resin mat 20 from the end of the concave streak 40. The water thus discharged to the outside of the resin mat 20 passes through the clearances M1 and M2 to the floor where the resin mat 20 is laid, for example, when the resin mat 20 is laid as shown in FIG. It is guided and drained from a drain provided on the floor.

  According to the resin mat 20 of the present embodiment described above, the water dropped on the surface 20A of the resin mat 20 is guided to the outside of the resin mat 20 by the inclination given to the bottom wall 43 of the concave streak 40. Unlike the related art, it is not necessary to form a through hole for water flow to the floor on the surface of the resin mat on which the feet are placed. Therefore, good drainage from the resin mat 20 to the floor can be realized while securing strength against warpage of the resin mat 20. For example, after laying a resin mat on a floor such as a balcony, if the resin mat is warped due to an environmental change (for example, a change in temperature or humidity) in a laying place, the warp may cause the resin mat to be torn. Less likely to occur.

  Further, in the resin mat 20 of the present embodiment, the formation of the concave stripes 40 reduces the resin thickness d2 of the portions where the concave stripes 40 are formed on the side surfaces 20C and the side surfaces 20D. Therefore, when cutting the resin mat 20 along the concave streak 40 according to the floor area of the installation location, the resin mat 20 can be easily cut with a small force. Further, since the bottom wall 43 of the concave streak 40 has a trough shape, the tip of the cutting blade moving on the bottom wall 43 from the side surface 20C toward the side surface 20D when cutting the resin mat 20 is formed by the trough 43a. You will be guided. Therefore, the resin mat 20 can be cut linearly without applying a ruler or the like to the cutting blade at the time of cutting.

  In the resin mat 20 of the present embodiment, the inclination given to the bottom wall 43 is given downward from the point M at the center of the concave streak 40 toward both the side surfaces 20C and 20D. This is hereinafter referred to as both gradients). Accordingly, the inclination of the bottom wall 43 is provided downward from the vicinity of the side surface 20C (20D) toward the side surface 20D (20C) (hereinafter, such a provided inclination is referred to as a single inclination). Thus, the degree of inclination (gradient) can be increased. In addition, by setting both gradients, the resin thickness d2 of the portion where the concave streak 40 is formed becomes thinner on both the side surface 20C and the side surface 20D. Therefore, cutting of the side surface of the resin mat 20 becomes easy on both the side surfaces 20C and 20D.

  Next, configurations in which the resin mat 20 of the above embodiment is provided with ventilation holes will be described as a first modified example and a second modified example. FIG. 6 is an explanatory diagram showing a side surface of a resin mat 120 as a first modification. The resin mat 120 shown in FIG. 6 has substantially the same components as the resin mat 20 of the first embodiment. In FIG. 6, the tens place of the reference numerals for the common parts are represented by the same numerals or letters as in FIG.

  As shown in FIG. 6, the resin mat 120 has a plurality of openings 150 on side surfaces 120C and 120E which are wall surfaces extending from the mounting surface 125 toward the back surface 120B. The openings 150 are formed at substantially equal intervals at nine locations on the side surface 120C and 17 locations on the side surface 120E. Further, similarly to the side surfaces 120C and 120E, openings 150 are formed in the side surfaces 120D and 120F (not shown).

  In this way, by forming the openings 150 in the side surfaces 120C to F around the resin mat 120, the openings 150 are blown into the laid resin mat 120 to be on the back side (between the resin mat 120 and the floor) of the resin mat 120. The entered wind is released to the outside of the resin mat 120 through the opening 150. Therefore, the curling of the resin mat 120 can be suppressed. The side surfaces 120 </ b> C to 120 </ b> F provided with the openings 150 are locations that are hardly affected by the warpage of the entire resin mat 120. Therefore, the formation of the openings does not impair the strength of the resin mat against warping.

  FIG. 7 is an explanatory view showing a perspective shape of a main part of a resin mat 220 as a second modification. The resin mat 220 shown in FIG. 7 has substantially the same components as the resin mat 20 of the first embodiment. In FIG. 7, for each common part, the tens place or less of the reference numeral is represented by the same numeral or alphabet as in FIG. In FIG. 7, for convenience of explanation, illustration of legs and connecting hooks is omitted.

  As shown in FIG. 7, the resin mat 220 includes a plurality of openings 250 on an inner wall surface 241 that is a wall surface from the mounting surface 225 toward the back surface 220B. Although not shown in FIG. 7, similarly to the inner wall surface 241, an opening 250 is formed on the inner wall surface 242 facing the inner wall surface 241.

  Even in the case where the openings 250 are formed in the inner wall surfaces 241 and 242 of the concave streak 240 in this manner, the openings 250 are blown into the laid resin mat 220 so as to blow the resin mat 220 on the back side (between the resin mat 220 and the floor). The wind that has entered is released to the outside of the resin mat 220 through the opening 250. Therefore, the curling of the resin mat 220 can be suppressed. Further, the inner wall surface 241 provided with the opening 250 is a portion that is hardly affected by the warpage of the entire resin mat 120. Therefore, the formation of the openings does not impair the strength of the resin mat against warping.

  Note that the first modification and the second modification may be combined to form openings in both the side surface around the resin mat and the opposing inner wall surface in the concave stripe. In this case, regardless of whether the resin mat is cut or not, all the outer peripheral side surfaces of the resin mat have openings. Therefore, the wind that has entered between the resin mat and the floor can be more reliably released to the outside of the resin mat.

  Although the embodiments of the present invention have been described based on the examples and the modified examples, the present invention is not limited to these examples and the like, and various modes may be provided without departing from the gist of the present invention. Of course, it can be carried out. For example, the outer shape of the resin mat 20 or the tile mat 10 and the groove shape of the concave streak 40 in the above embodiment can be appropriately changed to other shapes.

  In the above embodiment, the inclination given to the bottom wall 43 of the concave streak 40 may be a single inclination. Further, the inclination given to the bottom wall 43 is a downward inclination from the side surface 20C and the side surface 20D on the short side to the point M, and a through hole for water flow is provided in the bottom wall 43 at the point M. It may be. With this configuration, the number of through holes (through the resin mat from front to back) provided in the resin mat can be reduced, so that the strength against warpage can be improved as compared with the related art.

  In the above embodiment, the gap between the resin mats 20 connected to each other and the gap between the resin mat 20 and the wall body KB are secured by providing the protrusions 27 on the side surfaces 12C to 12F. Can be realized by a configuration other than the convex portion 27. For example, a groove may be formed by cutting the side surfaces 12C to 12F of the resin mat 20 from the front surface 20A to the rear surface 20B, and the gap may be secured by the groove.

  In the above embodiment, eight rows of the concave stripes 40 are formed in the resin mat 20 in parallel with each other. However, the number of the concave stripes 40 can be appropriately increased or decreased according to the cutting pitch of the resin mat 20. For example, when cut along the line tt as in the example of FIG. 4A, a portion where the mats 10 and 20 are not laid on the floor FL (hereinafter referred to as an unlaid portion) is slightly formed. Would. On the other hand, if a resin mat having more concave streaks 40 is used, cutting can be performed at a finer pitch, and the area of the unlaid portion can be further reduced.

  In the above embodiment, the resin mats 20 are provided with the plurality of rows of the ridges 40 at substantially equal intervals. However, the intervals between the ridges 40 may be varied depending on the position on the resin mat 20. For example, in FIG. 1A, a configuration in which the interval between the concave streaks 40 is reduced from the side surface 20F to the side surface 20E can be considered. In this way, it is possible to cut the resin mat 20 at a fine pitch on the side that is not connected to another mat, and it is possible to effectively reduce the area of the unlaid portion.

  In the above embodiment, the concave streak 40 is formed in a direction substantially parallel to the side surfaces 20E and 20F, but the concave streak 40 may be formed in a direction substantially parallel to the side surfaces 20C and 20D. Further, the concave stripes 40 may be formed in both directions substantially parallel to the side surfaces 20E and 20F and in directions substantially parallel to the side surfaces 20C and 20D, and the concave stripes 40 may cross each other. In this case, when the resin mat 20 is connected to the tile mat 10, the concave streak 40 is provided at a position in line with the joint corresponding portion of the tile mat 10, and the concave streak 40 connected to the joint equivalent portion is connected to the joint corresponding portion. It is also preferable to form the same width. When the resin mat 20 is laid in combination with the tile mat 10, the appearance becomes such that joints are connected between the tile mat 10 and the resin mat 20, and the design can be enhanced.

  Next, another modified example will be described. The following modification is characterized in that the mounting surface 25 which is the top surface of the ridge 50 is repeatedly provided with irregularities. FIG. 8 is an explanatory view showing the surface of the resin mat 320 of the third modification, and FIG. 9 is an enlarged cross-section showing a part of a cross section taken along line 9-9 in FIG.

  As shown in the drawing, the resin mat 320 of this modification has a top surface concave streak 321 and a top surface convex streak 322 along the mat longitudinal direction on the mounting surface 25 which is the top surface of each ridge 50. In this modified example, by setting the formation pitch of the top surface convex ridge 322 to about 2 mm, the anti-slip effect can be exhibited by repeating the convex ridge and the concave ridge on the mounting surface 25. In this case, it is preferable to set the above-mentioned pitch to be about 1 to 3 mm, because it is possible to suppress the inadvertent clogging with the concave streak while having the slip prevention effect.

  In this modification, similarly to the above-described concave streak 40, the top streak concave streak 321 on the mounting surface 25 also has an inclination at the concave streak bottom toward the left and right sides of the mat in FIG. In this case, the ridge 50 may be made thicker at the top than in the above-described embodiment, and may be inclined so that the bottom of the top ridge 321 is higher at the center of the mat and lower at the left and right sides (left and right sides of the mat). . In this way, the water that has fallen on the top surface (mounting surface 25) of the ridge 50 can be guided to the outside of the mat by the top surface concave ridge 321. Therefore, drainage can be further improved.

In the fourth modified example, in addition to the repetition of the unevenness on the top surface of the ridge 50, the unevenness has a notch. FIG. 10 is an explanatory view showing the surface of a resin mat 320A of a fourth modification, and FIG. 11 is an enlarged cross-section showing a part of a cross section taken along line 11-11 in FIG.
As shown in the figure, the resin mat 320 </ b> A has notch grooves 325 on the top surface of the protrusion 50 on the top surface of the protrusion 50 in addition to the above-described recess 321 on the top surface and the protrusion 322 on the top surface. The cutout groove 325 forms a groove in one convex ridge 50 toward the adjacent concave ridge 40. Therefore, in this modified example, the water that has fallen on the top surface (the mounting surface 25) of the ridge 50 is guided to the notch groove 325 by the top-surface concave streak 321 and is dropped into the concave streak 40 via this notch groove to be drained.

In the fifth modified example, when repeating the unevenness on the top surface of the ridge 50, the direction is set so as to cross the top surface of the ridge 50 and head toward the adjacent recess 40. FIG. 12 is an explanatory diagram illustrating a surface of a resin mat 320B according to a fifth modification.
Even in the illustrated resin mat 320 </ b> B, water that has fallen on the top surface (the mounting surface 25) of the ridge 50 can be dropped from the top surface concave ridge 321 into the concave line 40 and drained. In this case, if the bottom of the top ridge 321 is inclined toward the side of the adjacent ridge 40, that is, from one ridge in the width direction of the top of the ridge 50 to the other ridge. If it is inclined toward, water can be surely dropped into the concave streak 40 from the top streak concave streak 321, which is more preferable.

In addition, the top surface concave ridge 321 and the top surface convex ridge 322 may be formed as follows in addition to the linear shape described above. FIG. 13 is an explanatory diagram showing a surface of a resin mat 320C of a sixth modification, and FIG. 14 is an explanatory diagram showing a surface of a resin mat 320D of a seventh modification.

In the zigzag shape and the wavy shape, the arrangement may be made to cross the top surface of the ridge 50 vertically in the figure as in FIG.

The eighth modification is characterized in that the length adjustment of the resin mat 20 is simplified. FIG. 15 is an explanatory view showing the surface of a resin mat 320E of an eighth modification, and FIG. 16 is a schematic perspective view of the resin mat 320E.
As shown in the drawing, the resin mat 320E of this modified example has V-shaped notched V-grooves 330 at equal pitches on the ridges 50 arranged with the ridges 40 interposed therebetween. The notch V-groove 330 may be formed such that the mounting surface 25 (top surface) of the ridge 50 is depressed in a V-shape, and the top of the ridge 50 is formed so as to be notched while leaving some thickness. You can also.

  As described above, according to the resin mat 320E having the notch V-groove 330, the resin mat can be easily cut along the notch V-groove 330 with a cutting tool such as a cutter knife, so that the length of the resin mat can be easily adjusted. . Since the groove shape is V-shaped, the cutting blade can be smoothly guided similarly to the case of the concave streak 40 described above, which is preferable.

  The pitch at which the notched V-grooves 330 are formed is determined in consideration of the tile placement state of the tile mat 10 (see FIG. 4) to which the resin mat 320E is to be attached. That is, as shown in FIG. 4, if the tile mat 10 has tiles arranged in three rows and columns, in the resin mat 320 </ b> E, the notch V-groove 330 is formed at the position between the tiles in the tile mat 10. Are formed so as to substantially coincide with. If the tile mat 10 is for placing tiles in two rows and columns, one notch V-groove 330 is formed at the center of the mat. That is, the pitch at which the notched V-grooves 330 are formed can be changed in accordance with the size of the tile to be placed on the tile mat 10.
