It is a vertical sectional view of the deck material fixture 1 by X-rays. The deck material fixture 1 includes a base 2, a head 3, and legs 4.

  As shown in the drawing, the base 2 has flaps 2a and 2b that protrude in the horizontal direction perpendicular to the longitudinal direction. The head 3 extends along the longitudinal direction of the base 2 and protrudes upward from the center of the top end surface of the base 2. The leg portion 4 protrudes downward from the center of the bottom surface of the base 2. Further, a vertical screw hole 5 penetrating from the top end surface to the bottom surface is formed in the center portion of the base 2.

  It should be noted that when the head 3 is tightened by inserting a screw into the screw hole 5, the screw head portion can be passed into the base 2 (or close to the top end surface of the base 2). In addition, a screw receiving portion 3a (a space for allowing the screw head portion to enter above the screw hole 5) is formed. Similarly, the screw threaded portion 4a (below the screw hole 5 is provided below the screw hole 5 so that the tip portion of the screw can be passed through the leg portion 4 and protruded below the leg portion 4. A space for allowing the tip portion to pass therethrough is formed.

  Further, the head 3 is formed with a locking groove 3b (locking means) for attaching the joint material 6A or the joint material 6B as shown in FIG. 6 (FIGS. 1, 3, and 5). reference). As shown in FIG. 1 and the like, the locking groove 3b extends along the longitudinal direction of the base 2 at the center of the head 3 in the width direction. On the other hand, on the bottom surfaces of the joint materials 6A and 6B, a locking protrusion 7 (see FIG. 6) having a width dimension that can be fitted in the locking groove 3b of the head 3 is formed so as to protrude downward. Has been.

  The joint material 6A shown on the left side of FIG. 6 is a closed type joint material, and the top end 13 is a gap so that the gap C between the deck materials 59 and 59 shown in FIG. The dimension is set to be substantially the same as C (substantially the same as the width of the head 3 of the deck material fixture 1). In addition, small ridges 13a and 13a that protrude slightly outward are formed on both side edges of the top end 13, and when these small ridges 13a and 13a are included, the joint material 6A The width dimension is slightly larger than the dimension of the gap C between the deck members 59 and 59. On the other hand, the joint material 6B shown on the right side of FIG. 6 is an open type joint material, and the top end portion 13 is smaller in width than the gap C so that the gap C between the deck materials 59 and 59 is reduced. Is set to

  Each joint material 6A, 6B has a cross-sectional shape (cross-sectional shape orthogonal to the longitudinal direction) that is the same as the end face shape shown in FIG. 6 (at least longer than the arrangement interval dimension of the joists), More preferably, it is formed as a member having a length dimension that is an integral multiple of the arrangement interval of the joists. Although the material is not particularly limited, it is preferably formed of a metal such as aluminum or a highly durable weather resistant plastic.

  When the deck material is fixed to the joist using this deck material fixing tool 1, as shown in FIG. 7 or FIG. 8, it is perpendicular to the longitudinal direction of the joist 8 on the joist 8. The deck material 9 is placed in the direction, and the flap 2b (2a) is inserted into the concave groove 10 (10 ') formed on the longitudinal side surface of the deck material 9 (9'). The screw 11 is inserted and tightened, and the tip end side is screwed into the joist member 8, and the deck material fixture 1 is screwed onto the joist member 8. Then, the deck material 9 (9 ') is pressed down by the flap 2b (2a) entering the concave groove 10 (10') and fixed on the joist material 8.

  Then, a joint material 6A (see FIG. 7) or joint material 6B (see FIG. 7) is formed in a gap formed between the deck materials 9 and 9 ′ (a size approximately equal to the width of the head 3 of the deck material fixture 1). 8), the locking ridge 7 is fitted into the locking groove 3b formed in the head 3 of the deck material fixture 1. As shown in FIG.

  In addition, when it is desired to completely close the space between the deck materials 9 and 9 ', a closed type joint material 6A is used. When the closed type joint material 6A is used, the width of the top end 13 is substantially equal to the gap C as described above, and the small protrusions 13a and 13a are formed on both side edges. Therefore, although the width dimension is larger than the gap C by the protrusion amount, it can be easily mounted by press-fitting into the gap C. After mounting, the small protrusions 13a and 13a are in close contact with the side edges of the deck materials 9 and 9 'and are stabilized.

  Moreover, as shown in FIG. 7, when the small groove 12 of the magnitude | size which the small protrusion parts 13a and 13a fit in the side edge of the deck materials 9 and 9 'is formed in the appropriate height position. The fitting state can be further stabilized by fitting the small protrusions 13a and 13a into the small grooves 12. Thus, when the joint material 6A is used, it is possible to completely avoid the trouble that the article falls from the gap C between the deck materials 9, 9 '. The joint material 6A and the deck materials 9 and 9 ′ are not in contact with each other in a watertight state. Therefore, rainwater or the like flowing into the gap C from the surface of the deck materials 9 and 9 ′ is used as the joint material 6A. And the deck materials 9 and 9 'ooze out from the contact portion and are discharged downward.

  On the other hand, when it is desired to sufficiently ensure drainage such as rainwater or air permeability, an open type joint material 6B is used as shown in FIG. When this joint material 6B is mounted in the gap C, gaps (about 1.5 mm each on the right and left of the joint material 6B) remain between the top end portion 13 and the side edges of the deck materials 9 and 9 '. Rain water or air is caused by the gaps (particularly, the gap E1 between the joint material 6B and the deck material 9 and the gap E2 between the deck material 9 'in the region D between the joists 8 and 8 shown in FIG. 9). Can be passed. In addition, since the size of the gap C is reduced, problems such as an article dropping trouble can be suppressed.

  Moreover, even if it uses either joint material 6A, 6B, since the head part of the screw 11 used in order to fix the deck material fixing tool 1 will be covered from upper direction by joint material 6A, 6B. The problem of losing aesthetics can be suitably solved, and a beautifully finished floor surface can be constructed.

  In the present embodiment, as a means for locking the joint materials 6A and 6B to the deck material fixture 1, a locking groove 3b is formed in the head 3 and fitted into the locking groove 3b. The locking ridges 7 that can be combined are formed on the bottom surfaces of the joint materials 6A and 6B, but they are replaced to form a locking ridge on the head 3 side, and the joint materials 6A and 6B side. You may make it form a locking groove in.
