Has a center portion extending in the vertical direction with a predetermined width, and has at least two ridges protruding laterally from the center portion on each of the left and right sides. Among them, with the intermediate position of the thickness of the deck material as a reference, the ridge of the sandwiching part of the connecting material that fits into the groove located above and below it will hit the back of the groove when installed It is preferable that one large groove and at least two small grooves are formed on each side edge of the deck material, and the large groove is formed at an intermediate position in the thickness direction of the deck material. Above and below the large groove It is preferable that at least one each is formed, and a large protrusion that fits into the large groove on the side edge of the deck material and a small protrusion that fits into the small groove are formed in the sandwiching portion of the connecting material. . Moreover, it is preferable that the thickness dimension of the center part of a connection material corresponds with the space | interval dimension of the side edges of the deck materials of the right and left both sides of a connection material.

  Furthermore, the connecting material is configured by a sandwiching portion that is sandwiched between side edges of adjacent deck materials and a lower support portion that comes into contact with the lower surface of the deck material at the time of mounting. It is preferable that the left and right supports respectively have a contact surface that protrudes to the left and right sides below the center portion, and has a contact surface that contacts and closely contacts the lower surface of each deck material when mounted.

  The connecting member for a deck material with a lighting device according to the present invention has a sandwiching portion, and the sandwiching portion has a center portion that extends in a vertical direction with a predetermined width and protrudes laterally from the center portion.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a partial plan view of a deck structure 1 (deck structure with a lighting fixture) according to the present invention. In this deck structure 1, the deck material 11 is arranged in parallel in a direction orthogonal to the longitudinal direction of the joists 20 on the joists 20 arranged in parallel at a predetermined interval. It is fixed.

  A gap 15 having a predetermined width (for example, 5 mm) is formed between the adjacent deck materials 11, and rainwater, sand, other dusts, etc. pass through the gap 15 from below the deck construction surface. Falls to the side and does not stay on the deck construction surface. In addition, the adjacent deck members 11 are connected to each other at the side edges 12 by a connecting member 21 for a deck member with lighting equipment (hereinafter simply referred to as a “connecting member 21”). The connecting member 21 is disposed at a position between two adjacent joists 20 and 20 adjacent to each other.

  FIG. 2 is a front view of the connecting member 21 shown in FIG. As shown in the figure, the connecting member 21 includes a sandwiching portion 22 sandwiched between the side edges 12 of the adjacent deck members 11 and the deck member 11 when mounted on the deck member 11 (see FIG. 1). And a lower support portion 23 in contact with the lower surface. The lower support portion 23 can be omitted. That is, it is possible to use a connecting member constituted only by the sandwiching portion 22. However, when the connecting member 21 having the lower support portion 23 is used, the strength of the entire deck can be increased and the connecting member 21 can be increased as compared with the case where the connecting member constituted only by the sandwiching portion 22 is used. Contributes to an increase in the intensity of LED lighting.

  FIG. 3 is a view showing a cross section near the side edge 12 of the deck material 11 and the connecting material 21 before being mounted, and FIG. 4 is a view showing a mounting state thereof. As shown in FIG. 3, in the present embodiment, the deck material 11 constituting the deck structure is one in which one large groove 13 and two small grooves 14 a and 14 b are formed on the side edge 12. It has been. The large groove 13 is formed at a middle position in the thickness direction of the deck material 11 so as to be 1/10 to 1/3 of the thickness dimension of the deck material 11 (about 1/4 in the present embodiment). The small groove 14 a is formed above the large groove 13, and the small groove 14 b is formed below the large groove 13.

  On the other hand, as described above, the connecting member 21 has the sandwiching portion 22 and the lower support portion 23, and the sandwiching portion 22 is a center projecting upward from the center of the lower support portion 23 with a predetermined width. Part 24, large protrusion 25 projecting from the substantially middle height of center part 24 toward the left and right sides, and small protrusion projecting left and right side above large protrusion 25, respectively. It is comprised by the protrusion 26 and the small protrusion 27 which protrudes toward the left and right sides below the large protrusion 25, respectively. The lower support portion 23 is configured by supports 29 a and 29 b that protrude toward the left and right sides below the center portion 24. The supports 29a and 29b each have a surface (contact surface 28) that contacts the lower surface of the deck material 11 when the connecting material 21 is mounted on the deck material 11.

  At the time of mounting on the deck material 11, the large protrusion 25 and the small protrusions 26 and 27 of the connecting member 21 are inside the large groove 13 and the small grooves 14 a and 14 b formed on the side edge 12 of the deck material 11. Are formed in positions and sizes so as to enter and fit into each of them (see FIG. 4). In addition, the upper and lower small protrusions 26 and 27 are sized and shaped so that the respective ends of the small protrusions 26 and 27 abut against the back of the small grooves 14a and 14b, respectively. Further, the support 29a, 29b of the connecting member 21 has left and right sides in a state where the large protrusion 25 and the small protrusions 26, 27 enter and fit into the large groove 13 and the small grooves 14a, 14b, respectively. The contact surfaces 28 are in close contact with the lower surface of the deck material 11.

  Further, the connecting member 21 has light emitting means (LED, light emitting diode) disposed therein, and the top portion emits light when power is supplied via a power supply cable. have. Specifically, as shown in FIG. 5 (an exploded perspective view of the connecting member 21), the connecting member 21 includes a pair of left and right bases 41a and 41b, an LED base 42, an upper cover 43, and a pair of front and rear light shields. It is comprised by cover 44a, 44b and a pair of male and female cable connectors 45a, 45b. The light shielding covers 44a and 44b adjust the size of the light emitting portion and prevent light leakage from the deck joint side 57 (see FIG. 5).

  The pair of left and right bases 41a and 41b have vertical joint surfaces 46a and 46b, respectively. The vertical joint surfaces 46a and 46b are respectively formed with joint protrusions 47 and joint holes 48. 46a and 46b face each other, the joining projection (not shown) of the base 41a is fitted into the joining hole 48 of the base 41b, and the joining projection 47 of the base 41b is joined to the joining hole (not shown) of the base 41a. ) Can be integrated by fitting in.

  When the bases 41a and 41b are joined and integrated, the lower support portion 23 is configured as shown in FIG. 6 (perspective view of the joined bases 41a and 41b), and the center portion 24 ( The lower half 24a is configured (see FIG. 3). In the lower half portion 24a of the center portion 24, the small protrusions 27 protrude from the left and right sides, and a base fixing portion 49 constituting the large protrusion 25 shown in FIG. 3 is formed above them. . The board | substrate fixing | fixed part 49 has the side wall 50 standingly arranged by the circumference | surroundings, and the LED board | substrate 42 (refer FIG. 5) is arrange | positioned inside it.

  As shown in FIG. 5, the LED base 42 has an LED 52 mounted in the center, and one end side of the power supply cable 53 is connected. As shown in FIG. 5, a hole (insertion hole 51) through which the power feeding cable 53 is inserted is formed in the bases 41 a and 41 b, and the bottom surface of the base fixing part 49 (inside the side wall 50) is formed. The opening 51a of the insertion hole 51 is formed. The power feeding cable 53 having one end connected to the LED base 42 extends to the outside of the bases 41a and 41b through the insertion hole 51, and the other end is connected to the cable connectors 45a and 45b.

  An upper cover 43 formed of a transparent synthetic resin is placed on the base fixing part 49. The upper cover 43 includes a cover portion 43a constituting the large protrusion 25 shown in FIG. 3 and a central standing portion 43b erected upward at the center in the left-right direction (a portion constituting the center portion 24 shown in FIG. 3). ) And the light emitting portion 43c formed at the center in the front-rear direction of the central standing portion 43b. The cover part 43a is mounted so as to cover the outside and the upper side of the side wall 50 of the base fixing part 49, whereby rainwater or dust enters the space in the side wall 50 of the base fixing part 49 where the LED base 42 is disposed. The intrusion of etc. is avoided.

  Engagement ridges 54 are formed along the longitudinal direction on the upper portion of the central standing portion 43b (position adjacent to the light emitting portion 43c), and the light shielding covers 44a and 44b are formed on these engagement ridges 54. Are installed respectively. The light shielding covers 44a and 44b are made of an opaque synthetic resin, and are intended to limit light irradiation using the LED 52 as a light source only to the light emitting portion 43c.

  The light shielding covers 44a and 44b include a flat plate-like portion constituting the small protrusion 26 shown in FIG. 3 and a joint side cover 55 extending downward from the outer end portion thereof. A dovetail groove 56 having a shape corresponding to the contour shape of the engaging protrusion 54 is formed on the lower side surface. The light shielding covers 44 a and 44 b are arranged so that the engaging ridge 54 of the upper cover 43 enters the dovetail groove 56 of the light shielding covers 44 a and 44 b, and the inner ends of the light shielding covers 44 a and 44 b are located on the upper cover 43. The upper cover 43 is attached by sliding until it comes into contact with the light emitting portion 43c.

  As shown in FIG. 1, a connecting member 21 is arranged between adjacent deck members 11, and the cable connectors 45a and 45b of each connecting member 21 shown in FIG. 5 are connected in series and connected to a power source. The LED 52 emits light in the material 21. Since the upper cover 43 is formed of a transparent synthetic resin, light is emitted from the light emitting portion 43c that transmits the light of the LED 52 and is not shielded by the light shielding covers 44a and 44b. It is possible to produce a light (illumination).

  In addition, the connection material 21 can be freely arrange | positioned in any position between adjacent joists 20 and 20 (refer FIG. 1). Accordingly, deck surface lighting of various designs can be configured according to purposes such as nighttime lighting, pedestrian guidance or guidance, or decoration. For example, in the case where virtual concentric circles are projected on the deck surface, the connecting material 21 is placed at the intersection between the concentric circles and the joints of the deck material 11 (the gap 15 between the adjacent deck materials 11 and 11 shown in FIG. 1). By arranging and illuminating, a concentric figure can be displayed on the deck surface, and a straight line, zigzag pattern, diamond figure, alphabet, number, other characters, etc. can be displayed.

  In addition, it is not necessary to form an insertion hole on the deck construction surface as in the conventional method, and it can be fixed simply by being sandwiched between the side edges 12 of the deck material 11, so that it is very easy to install the lighting fixture. In addition, once installed, the position can be easily changed within the deck joint.

  Further, as shown in FIG. 4, the light emitting portion 43c has such a size that the upper surface does not protrude upward from the deck constituting surface when mounted between the deck materials 11a and 11b. In the case of the conventional method (a method in which an insertion hole is formed in the deck material, and a lighting fixture is inserted and fixed in this insertion hole via a fixture), the frame of the fixture or the top cover is located above the deck construction surface. Therefore, in this embodiment, as described above, the light emitting portion 43c is on the deck construction surface, because the pedestrian crawled or got caught and became an obstacle to the pedestrian. Since the structure does not protrude upward, problems such as obstacles to pedestrians or damage caused by collision of moving objects or falling objects can be suitably avoided.

  In addition, when the conventional method is used, the insertion hole is formed in the deck material, so that the strength of the deck material itself may be reduced and the deck material may be bent, cracked, broken, etc. In the deck structure 1, since the lighting fixture (the connecting member 21) is mounted between the adjacent deck members 11, it is not necessary to form an insertion hole in the deck member 11. For this reason, the deck structure 1 of the present embodiment has the advantage that the strength of the deck material 11 can be improved as well as the problem of the strength reduction of the deck material 11 does not occur. Specifically, since the side edges 12 of the adjacent deck members 11 are connected to each other by the connecting member 21 at a position between two adjacent joists 20 and 20, one deck member 11 or two adjacent two deck members 11 are adjacent to each other. Even when a load is concentrated on the joints (connecting portions) of two deck materials 11, only one deck material 11 sinks or the adjacent deck materials 11 are not relatively inclined. As a result, the load applied to one deck material 11 or the joint portion is effectively transmitted and distributed to the adjacent deck material 11, and as a result, compared to the conventional one, the strength against concentrated load and impact load is increased. A dramatic improvement in (load bearing strength) can be expected.

  Specifically, for example, when a load is applied to the left deck material 11a out of the two deck materials 11a and 11b shown in FIG. 4, the large grooves 13 of the deck materials 11a and 11b, Since the large protrusion 25 and the small protrusions 26 and 27 (see FIG. 3) of the connecting material 21 enter and fit into the small grooves 14a and 14b (see FIG. 3), the connecting material 21 Since the contact surfaces 28 (see FIG. 3) of the left and right supports 29a and 29b are in close contact with the lower surfaces of the deck materials 11a and 11b, respectively, the left deck material 11a is displaced downward ( The deviation in the vertical direction) is not allowed, and the load applied to the left deck material 11a is effectively transmitted and distributed to the right deck material 11b.

  Further, when the load is applied to the left deck material 11a intensively, if the right deck material 11b is inclined to the left, that is, the left side edge 12b of the right deck material 11b is the right side edge. When the joint between the horizontal left deck material 11a and the lower left deck material 11b is allowed to be bent in a valley shape by rotating downward about 12b ′, the left deck material 11a will be displaced downward together with the left side edge 12b of the right deck material 11b. In the present embodiment, as described above, the small protrusion 26 (the thickness of the deck material 11) of the connecting material 21. The tip of the small protrusion above the intermediate position in the vertical direction is configured to abut to the back of the small groove 14a of the deck material 11 (the small groove above the intermediate position in the thickness direction of the deck material 11). Therefore, the interval between the upper portions of the side edges 12a and 12b of the left and right deck materials 11a and 11b (the portion above the intermediate position in the thickness direction of the deck material 11) can be made narrower than the state shown in FIG. Therefore, even when a load is applied intensively to the left deck material 11a, it is avoided that the right deck material 11b is inclined downward to the left. As a result, the left deck material 11a (and The downward displacement of the left side edge 12b) of the right deck material 11b is not allowed, and the load applied to the left deck material 11a is effectively transmitted and distributed to the right deck material 11b. .

  Further, when a load is applied to the left deck material 11a intensively, when the left deck material 11a is inclined to the left, that is, the left side edge 12a 'of the left deck material 11a is on the right side. When the joint between the horizontal right deck material 11b and the left lower deck material 11a is allowed to be bent in a mountain shape by rotating downward with the edge 12a as a base point, the left deck material Although the left side edge 12a ′ of 11a is further displaced downward together with the deck material (not shown) located on the left side thereof, in this embodiment, as described above, the small size of the connecting material 21 is small. The tip of the protrusion 27 (small protrusion below the intermediate position in the thickness direction of the deck material 11) is the small groove 14b of the deck material 11 (small groove below the intermediate position in the thickness direction of the deck material 11). Thrust to the back Since it is comprised so that it may constitute, the space | interval of the lower part (part below the intermediate position of the thickness direction of the deck material 11) of the side edges 12a and 12b of the left and right deck materials 11a and 11b is shown in FIG. Therefore, even when a heavy load is applied to the left deck material 11a, it is avoided that the left deck material 11a is inclined downward to the left. The left side edge 12a 'of the deck material 11a (and the left side deck material not shown) is not allowed to move downward, and the load applied to the left deck material 11a is applied to the right deck material 11b. It will be transmitted and distributed effectively.

  Further, when a load is intensively applied to the joint portions (the portions where the connecting material 21 is mounted) of the left and right deck materials 11a and 11b, the left and right deck materials 11a and 11b are formed in a V shape (valley shape). If it is allowed to bend, the joint portion will be displaced downward, but as described above, the tip of the small protrusion 26 of the connecting member 21 hits the back of the small groove 14a of the deck member 11. (See FIG. 3), the distance between the upper portions of the side edges 12a and 12b of the left and right deck members 11a and 11b cannot be reduced. For this reason, the left and right deck members 11 are V-shaped. Bending is avoided, and as a result, the downward displacement of the joint portion is not allowed, and the load is effectively transmitted and distributed to the surroundings.

  As described above, in the present embodiment, even when a load is concentrated on one deck material 11 or a joint, those loads are suitably transmitted and distributed to the surroundings. The strength against load and impact load can be improved extremely effectively compared to the prior art.

  FIG. 7 is a cross-sectional view of a conventional deck member 81, 82 arranged in parallel with a gap 15 of a predetermined width on a joist (not shown) at an intermediate position of the joist, and no load is applied. It is a figure which shows the example of a deformation | transformation aspect when a fixed load is applied to the case and the center deck materials 81 and 82. More specifically, FIG. 7A is a diagram showing a state in which no load is applied to the conventional deck material 81 in which no groove is formed on the side edge, and FIG. FIG. 7 (3) is a diagram showing a state in which a load is applied to the central deck member 81, and FIG. 7 (3) shows a central deck among the conventional deck members 81 whose side edges are connected by the connecting member 91 (comparative example). FIG. 7 (4) shows a state in which a load is applied to the material 81. FIG. 7 (4) shows a state in which the load is applied to the center deck material 82 among the conventional deck materials 82 whose side edges are connected by the connecting material 92 (comparative example). It is a figure which shows the state applied.

  FIG. 8 is a cross-sectional view of the deck material 11 whose side edges are connected to each other by the connecting material 21 used in the deck structure 1 of the present embodiment, in the middle position of the joist material. It is a figure which shows the example of a deformation | transformation aspect when the same load is applied to.

  As shown in FIG. 7 (1), when the conventional deck material 81 is arranged without connecting the side edges with a gap 15 between them, when a predetermined load is applied at the intermediate position of the joist material, For example, as shown in FIG. 7 (2), only the central deck material 81 on which the load is applied is bent downward.

  Further, as shown in FIG. 7 (3), a conventional deck material 81 is connected to a connecting material 91 (comparative example) (the center portion 24 of the sandwiching portion 22 of the connecting material 21 and the lower support portion 23 in this embodiment). However, the portion corresponding to the holding portion 22 does not have the portions corresponding to the large protrusion 25 and the small protrusions 26 and 27, and the center portion 24 of the holding portion 22 7), the height of the corresponding portion is set to be equal to or approximately half the thickness of the deck material 81), and the central deck material 81 has the same size as the example of FIG. When a large load is applied, since the connection with the adjacent deck material 81 is incomplete, the load is not transmitted well, and the amount of deflection (the amount of sinking from the standard position B) is the same as in the case of FIG. The deck material 8 is almost the same as in the case of FIG. Only the central deck member 81 is to flex downward displacement of the side surface is generated.

  As shown in FIG. 7 (4), the conventional deck material 82 has a connecting material 92 (comparative example) (a portion corresponding to the sandwiching portion 22 and the lower support portion 23 of the connecting material 21 in this embodiment). In addition, although it has a portion corresponding to the large protrusion 25, it does not have a portion corresponding to the small protrusions 26 and 27, and the height dimension of the portion corresponding to the center portion 24 of the sandwiching portion 22 is the same. In this case, when a load having the same size as the example of FIG. 7 (2) is applied to the central deck material 82, the deck material 82 is set to about 2/3 of the thickness of the deck material 82). Although the load is transmitted to the adjacent deck material 82 to some extent, the inclination of the adjacent deck material 82 is allowed, and as a result, the amount of deflection is almost the same as in the case of FIG. When the deflection increases, Side or coupling member 92 of the timber 82 is to be broken.

  In contrast to these examples, in the deck structure 1 of the present embodiment, as shown in FIG. 8, when a load having the same magnitude as that in the example of FIG. The inclination and deviation of the deck material 11 to be performed are suppressed, and the load is transmitted and distributed to the surroundings. Accordingly, the strength against concentrated load and impact load is improved, and the sinking (generation of deflection) of the deck material 11 to which the load is concentrated can be suppressed as much as possible.

  FIG. 9 is a cross-sectional view of the conventional deck members 81 and 82 arranged in parallel with a gap 15 of a predetermined width on a joist (not shown) at an intermediate position of the joist, and no load is applied. It is a figure which shows the example of a deformation | transformation aspect when a fixed load is applied to the joint part of the case and the deck materials 81 and 82. FIG. More specifically, FIG. 9A is a diagram showing a state in which no load is applied to the conventional deck material 81 in which no groove is formed on the side edge, and FIG. FIG. 9 (3) is a diagram showing a state in which a load is applied to the joint portion of the deck material 81. FIG. 9 (3) shows the load applied to the joint portion of the conventional deck material 81 in which the side edges are connected to each other by the connection material 91 (comparative example). FIG. 9 (4) is a diagram showing a state in which a load is applied to the joint portion of the conventional deck material 82 in which the side edges are connected by the connecting material 92 (comparative example).

  FIG. 10 is a cross-sectional view of the deck material 11 whose side edges are connected to each other by the connecting material 21 used in the deck structure 1 of the present embodiment, at an intermediate position of the joist material. It is a figure which shows the example of the deformation | transformation aspect when the same load is applied to a part.

  As shown in FIG. 9 (1), when a conventional deck material 81 is arranged with the gap 15 left without connecting the side edges, a predetermined load is applied to the joint portion of the deck material 81. As shown in FIG. 9 (2), the deck material 81 on both sides of the joint portion is bent and greatly sunk as a whole, and the joint portion to which the load is applied sinks most deeply, and the decks on both sides of the joint portion are deepened. All the materials 81 are inclined in a valley shape.

  Further, as shown in FIG. 9 (3), a conventional deck material 81 is replaced with a connecting material 91 (comparative example) (a portion corresponding to the sandwiching portion 22 and the lower support portion 23 of the connecting material 21 in this embodiment). However, the portion corresponding to the sandwiching portion 22 does not have the portion corresponding to the large protrusion 25 and the small protrusions 26, 27, but the portion corresponding to the center portion 24 of the sandwiching portion 22. 9), the load of the same magnitude as that in the example of FIG. 9 (2) is applied to the joint portion of the deck material 81. In this case, since the connection with the adjacent deck material 81 is incomplete, the load is not transmitted, and the amount of deflection (the amount of sinking from the standard position B) is smaller than that in the case of FIG. As in the case of FIG. 9 (2), the deck materials 81 on both sides of the joint portion are all To sink deflects and sinks joints which load is applied is deepest, a state where the joint portion on both sides of the deck material 81 are both inclined to the trough.

  As shown in FIG. 9 (4), the conventional deck material 82 is connected to a connecting material 92 (comparative example) (a portion corresponding to the sandwiching portion 22 and the lower support portion 23 of the connecting material 21 in this embodiment). In addition, although it has a portion corresponding to the large protrusion 25, it does not have a portion corresponding to the small protrusions 26 and 27, and the height dimension of the portion corresponding to the center portion 24 of the sandwiching portion 22 is the same. 9 is set to approximately 2/3 of the thickness of the deck material 82), and the joint portion of the deck material 82 is subjected to the same load as the example of FIG. 9 (2). Although the load is transmitted to the adjacent deck material 82 to some extent, the inclination of the deck material 82 on both sides of the joint portion is allowed. As a result, the amount of deflection is small compared to the case of FIG. However, deflection still occurs.

  In contrast to these examples, in the deck structure 1 of the present embodiment, as shown in FIG. 10, when a load having the same magnitude as the example of FIG. 9 (2) is applied to the joint portion of the deck material 11, Inclination and displacement of the deck material 11 on both sides of the joint are suppressed, and the load is transmitted and distributed to the surroundings. Accordingly, the strength against concentrated load and impact load is improved, and the sinking (generation of deflection) of the deck material 11 to which the load is concentrated can be suppressed as much as possible.

  In addition, in the deck structure 1 of this embodiment, as shown in FIG. 3, as the deck material 11, one large groove 13 and two small grooves 14a and 14b are formed in each side edge 12. As the connecting member 21, a material having a large protrusion 25 and a small protrusion 26, 27 formed on the center portion 24 is used. For example, the protrusions in the sandwiching portion 22 of the connecting member 21 do not necessarily have to be formed in three pieces on one side, and as shown in FIG. 11, the protrusions (large protrusions 25) are on one side. It is also possible to use a connecting member 21 formed with only one strip. In addition, the deck material 11 may be one in which only one groove (large groove 13) is formed on each side edge 12.

  However, in this case, there is an interval between the upper portions (portions above the large groove 13) of the side edges 12 of the deck material 11 on both the left and right sides of the connecting member 21 or between the lower portions (portions below the large groove 13). The center portion 24 of the connecting member 21 interposed between them stretches, so that even when no extra load is applied or when a concentrated load is applied, the center portion 24 is hardly further reduced. The size and shape of the center portion 24 of the connecting member 21 need to be set so as to exert an action. For example, it is preferable that the distance between the side edges 12 of the deck material 11 on the left and right sides of the connecting material 21 is set to 3 to 10 mm. It is preferable that they match. The upper and lower thickness dimensions of the deck material 11 are preferably 20 to 50 mm, the height dimension of the large groove 13 is 3 to 38 mm, and the depth dimension of the large groove 13 is preferably 5 to 15 mm.

  Furthermore, it is possible to use a connecting member 21 in which two ridges are formed on one side of the sandwiching portion 22, and the deck material 11 is also formed with two grooves on each side edge 12. Things can also be used.

  However, in this case, it is necessary to form the grooves of the deck material 11 one by one above and below the intermediate position of the thickness dimension of the deck material 11. It is preferable to configure so as to enter and fit into the respective grooves when mounting. In addition, it is preferable that the protrusions fitted into the grooves formed above the intermediate position of the thickness dimension of the deck material 11 have a size and a shape so as to hit the back of the groove. It is preferable that the protrusions fitted in the groove formed below the middle position of the thickness dimension of 11 have a size and shape so as to hit the groove.

  In addition, the term “size and shape so as to hit to the back” as used herein refers to an interval between grooves on the upper side edge 12 of the deck material 11 on both the left and right sides of the connecting material 21 (upper side edge 12), Alternatively, the gap between the lower grooves (the lower portions of the side edges 12) is extended by the ridges fitted inside them, so that even when no extra load is applied, a concentrated load is applied. In this case, it means that the size and shape have such an effect that they are not further reduced.
