In the following, for convenience, the upper and lower sides are specified based on the posture of the deck material when the floor surface is configured.

  FIG. 1 shows a deck material according to an embodiment of the present invention. The deck material exemplified here is used when a floor surface of a space provided outdoors such as a balcony is configured, and includes a deck body 10 and a groove cover 20.

  The deck body 10 is an extruded shape member formed of a relatively hard synthetic resin, for example, hard PVC (polyvinyl chloride), and is formed in a long hollow plate shape. More specifically, as shown in FIGS. 1 and 2, the deck body 10 has a plurality of partition walls between the bottom wall portion 11 and the upper wall portion 12 when viewed in a cross section orthogonal to the longitudinal direction. A plurality of independent hollow portions 14 are formed between the bottom wall portion 11 and the upper wall portion 12. The bottom wall portion 11, the upper wall portion 12, and the partition wall portion 13 each have a thin plate shape. At one side edge of the deck body 10, the upper wall portion 12 protrudes beyond the bottom wall portion 11, and the protruding edge portion of the upper wall portion 12 is bent downward at a substantially right angle to constitute the hook portion 15. doing. At the other side edge of the deck body 10, the bottom wall portion 11 protrudes beyond the upper wall portion 12, and the protruding edge portion of the bottom wall portion 11 bends upward at a substantially right angle to cause the hook receiving portion 16 to be bent. It is composed. When the deck main body 10 having the hook portion 15 and the hook receiving portion 16 is arranged in the same direction, the hook portion 15 can enter the hook receiving portion 16.

  As shown in FIGS. 2 to 4, the deck body 10 is provided with a groove 100. The groove 100 is open at the top surrounded by the bottom wall portion 11 and the left and right side wall portions 110, and is formed over the entire length in the longitudinal direction. The bottom wall portion 11 of the groove 100 is provided with a thick portion 11a at the center portion thereof. The side wall 110 of the groove 100 has an upper side wall portion 111, an inclined side wall portion 112, a lower side wall portion 113, and a locking side wall portion 114, respectively.

  The upper side wall portion 111 extends substantially vertically downward from the upper wall portion 12. A guide fin portion 115 is provided in the upper side wall portion 111. The guide fin portion 115 has a thin plate shape that protrudes substantially horizontally from a portion that becomes an opening edge of the groove 100 in the upper side wall portion 111 toward a direction close to each other. The upper surface of the guide fin portion 115 is set to be lower than the upper surface of the upper wall portion 12. The guide fin portion 115 is provided with a hanging portion 116 at each protruding edge portion. The hanging portion 116 is formed so as to protrude downward from the lower surface of the guide fin portion 115. The inclined side wall portion 112 extends from the lower end portion of the upper side wall portion 111 so as to be inclined in a direction gradually approaching each other. Each inclined side wall portion 112 is formed to have an inclination angle of approximately 45 °, and the portion facing the inside of the groove 100 constitutes a flat support surface 112a. The lower side wall portion 113 extends substantially vertically from the lower end portion of the inclined side wall portion 112 downward. The locking side wall portion 114 extends from the lower end portion of the lower side wall portion 113 in a direction away from each other, and then extends downward so as to be gradually inclined toward each other toward the bottom wall portion 11. A locking surface 114 a is formed at the lower end of the lower side wall portion 113.

  The groove cover 20 is disposed over the entire length of the groove 100 of the deck body 10, and as shown in FIG. 3, the upper surface cover portion 21, the connecting plate portion 22, the substrate portion 23, and the locking leg portion 24 are arranged. Have. The upper surface cover portion 21 has a plate shape having a dimension that can be disposed between the upper surfaces of the guide fin portions 115. The plate thickness of the upper surface cover portion 21 is set to a size smaller than the step from the upper surface of the guide fin portion 115 to the upper surface of the upper wall portion 12. The connecting plate portion 22 has a pair of flat plate shapes that protrude downward from the lower surface of the upper surface cover portion 21. The substrate portion 23 has a plate shape connected to the lower end portion of the connecting plate portion 22 in a state substantially parallel to the upper surface cover portion 21. The substrate portion 23 is formed in a plate shape having a dimension that is larger than the interval between the connecting plate portions 22 and slightly smaller than the interval between the lower side wall portions 113, and both side edges are connected plate portions. It protrudes from 22 toward the side. The locking leg portion 24 is gradually widened from both side edges of the base plate portion 23 toward the lower side, and is gradually widened away from each other toward the lower portion of the widened portion 24a. It has a locking piece portion 24b extending so as to be bent. At the bent portion of the expanded portion 24a and the locking piece portion 24b, a locking ridge portion 24c that protrudes outward is provided.

  Here, when no external force is applied, the locking leg 24 of the groove cover 20 has a lower side wall in which the maximum expanded dimension a of the expanded portion 24a is provided in the deck main body 10 as shown in FIGS. The portion 113 is configured to be larger than the mutual interval b. If the locking leg portion 24 is elastically bent, the expanded dimension of the expanded portion 24a can be made smaller than the mutual interval b of the lower side wall portion 113. The strip portion 24 c can be brought into contact with the locking surface 114 a of the lower side wall portion 113. As shown in FIG. 1, when the locking protrusion 24c of the locking leg 24 is brought into contact with the locking surface 114a of the lower side wall 113, the lower end of the locking piece 24b is a deck. The main body 10 is set so as to be separated from the bottom wall portion 11 of the main body 10.

  Further, the height dimension of the groove cover 20 is such that the upper surface of the upper surface cover portion 21 is the same as when the locking protrusion 24c of the locking leg 24 is brought into contact with the locking surface 114a of the lower side wall portion 113, respectively. It is set so that it substantially coincides with the upper surface of the deck body 10 and the substrate portion 23 is positioned above the upper end of the lower side wall portion 113.

  On the other hand, as shown in FIG. 3, the groove cover 20 is provided with contact fin portions 25 at both side edges of the substrate portion 23. The contact fin portions 25 extend upward so as to gradually incline from the substrate portion 23 in directions away from each other, and constitute flange portions 26 on both sides of the connecting plate portion 22. The inclination angle of the contact fin portion 25 from the horizontal plane is set to be slightly smaller than the inclined side wall portion 112 when no external force is applied. Further, as shown in FIGS. 3 and 4, the maximum expansion dimension c of the contact fin portion 25 is set to be larger than the mutual interval d of the upper side wall portions 111.

  Similar to the deck body 10, the groove cover 20 is an extruded shape member formed of synthetic resin. However, in the groove cover 20 of the present embodiment, the upper surface cover portion 21, the connecting plate portion 22, the substrate portion 23, and the locking leg portion 24 are formed of a relatively hard synthetic resin, for example, hard PVC (polyvinyl chloride). On the other hand, the contact fin portion 25 has a composite material structure formed of a relatively soft synthetic resin, for example, soft PVC (polyvinyl chloride).

  In the deck material that constitutes the deck body 10 and the groove cover 20 as described above, the deck body 10 is disposed above a base such as a joist with the groove 100 opened, and the thickness formed on the bottom wall portion 11 of the groove 100. It is laid by screwing the screw member B to the ground via the meat part 11a. If a plurality of deck main bodies 10 are arranged side by side while the hook portions 15 of the deck main body 10 enter the hook receiving portions 16, the floor surface of the balcony can be configured. Although not clearly shown in the drawing, it is preferable to interpose a sealant between the head of the screw member B and the bottom wall 11 of the groove 100.

  Next, the groove cover 20 is attached to the groove 100 of each deck body 10. Specifically, when the groove cover 20 is pushed from above with the groove cover 20 disposed in the groove 100 of the deck main body 10, the locking legs 24 are guided along the support surface 112 a of the side wall 110 and approach each other. Will bend elastically. Eventually, when the expansion dimension of the locking leg portion 24 becomes smaller than the interval between the lower side wall portions 113, the locking ridge portions 24c pass between the lower side wall portions 113, and the engagement of the lower side wall portions 113 is increased. Since the contact is made with the stop surface 114a, the movement of the groove cover 20 in the direction of dropping from the groove 100 is restricted. In this state, as shown in FIG. 1, the upper surface cover portion 21 closes the opening of the groove 100. Accordingly, it is possible to prevent a situation where dust or dust enters and stays in the groove 100.

  On the other hand, the contact fin portion 25 of the groove cover 20 is elastically deformed to pass between the guide fin portions 115, and the respective leading edge portions are pressed against the upper side wall portion 111. In this state, even when water such as rainwater enters the inside of the groove 100, there is a risk of passing between the tip edge portion of the contact fin portion 25 and the upper side wall portion 111 that are pressed against each other and going downward. And is received by a flange portion 26 formed between the upper surface of the contact fin portion 25 and the connecting plate portion 22.

  Here, in this deck member, a guide fin portion 115 is provided at a position to be an opening edge portion of the groove 100. For this reason, the water that has entered the groove 100 along the upper surface of the deck body 10 is guided to the proximal end side of the contact fin portion 25 by the upper surface of the guide fin portion 115. Furthermore, since the water guided by the guide fin portion 115 is prevented from dripping by the hanging portion 116 and wrapping around the lower surface of the guide fin portion 115, the water is directly applied to the contact portion between the contact fin portion 25 and the upper side wall portion 111. The situation of dripping does not occur. As a result, the water that has entered the groove 100 of the deck main body 10 is received by the flange 26, and is transferred to the end of the deck main body 10 as it is and discharged to the outside. There is no fear of reaching the screwed bottom wall 11. Accordingly, it is possible to prevent a situation where water leaks below the deck body 10 through the bottom wall portion 11 of the groove 100 through which the screw member B passes.

  In addition, in this deck member, the support surface 112a is disposed at a position below the contact fin portion 25. Therefore, even when the contact fin portion 25 is bent due to deterioration over time, the contact fin 112 is in contact with and supported by the support surface 112a, and the tip edge portion of the contact fin portion 25 is deformed to be bent downward. Since it does not come and water tightness is not impaired, it is possible to reliably prevent leakage of water over a long period of time. The support surface 112a is closer to the lower surface of the contact fin portion 25 toward the tip edge of the contact fin portion 25 because the inclination angle from the horizontal plane is larger than that of the contact fin portion 25. As a result, the portion where the support surface 112 a abuts against the abutment fin portion 25 is a location close to the tip edge of the abutment fin portion 25. Therefore, when the support surface 112a is in contact with the lower surface of the contact fin portion 25, there is no possibility that the leading edge of the contact fin portion 25 is separated from the upper side wall portion 111.

  In the above-described embodiment, the deck material having three hollow portions 14 on both sides of the groove 100 is illustrated, but the number of hollow portions is not necessarily three. Further, although the inclined side wall portion 112 of the side wall portion 110 constituting the support surface 112a is exemplified as having an inclination angle of approximately 45 °, the inclination angle of the support surface is not necessarily limited to this, and the inclination from the horizontal plane is not limited thereto. Other angles may be used as long as the angle is larger than the contact fin portion of the groove cover. Furthermore, although the deck main body 10 and the groove cover 20 are exemplified by those made of an extruded shape molded from a synthetic resin, the present invention is not limited to this. For example, the groove cover 20 excluding the deck main body 10 and the contact fin portion 25 may be made of wood or synthetic wood in which synthetic resin contains wood powder, or may be made of metal. Further, the deck main body 10 and the groove cover 20 do not need to be constituted by an extruded material.
