Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of the deck according to the present invention with the middle omitted, FIG. 2 is a perspective view of an end fitting for fixing to the end of the joist and fixing the deck material at the end, and FIG. 3 is a deck. FIG. 4 is a perspective view of the main part showing a state in which the start deck material is fixed to the joist using the end connecting metal fittings, which are installed on the protrusions of the material to fix the deck material to the joist. 5 is a perspective view of the main part showing a state in which the deck material is fixed to the joist using the intermediate connection metal fitting, and FIG. 6 is a perspective view of the main part showing a state in which the terminal deck material is fixed using the end connection metal fitting. It is. The same reference numerals are used for members that are the same as or equivalent to those shown in FIG.

  Among the connection fittings improved in the present invention, the end connection fitting 3A includes an upper surface portion 31 placed on the upper surface of the joist 1 and both longitudinal ends of the upper surface portion 41 as shown in FIG. A hanging piece 32 bent downward from the portion and a curved locking piece 33 rising from one side of the upper surface portion 31 and having a substantially S-shaped section are integrally formed. The upper surface portion 31 and the drooping pieces 32 on both sides are continuous in a downward U-shape and can be saddleed on the joist 1 from above the joist 1. Then, by screwing the screw into the joist 1 from the screw through hole 32 h provided in the hanging piece 32, the end connection fitting 3 </ b> A can be fixed to the joist 1.

  In order to fix the end connection fitting 3A to the joist 1, it is also possible to provide a screw through hole in the upper surface portion 31 and screw the screw into the joist 1 from the screw through hole. However, when the tip of the ridge 21 of the deck material 2 is close to the side surface of the deck material, the width of the upper surface portion 31 is set when the side surface on the one end side of the deck material is attached close to the end surface of the joist 1. Therefore, it is difficult to screw a screw from the upper surface portion 31 to the joist 1. In order to eliminate such difficulties, it is desirable to provide a hanging piece 32 of the end connecting fitting 3A and screw a screw into the joist from this hanging piece as in the illustrated example. When such a hanging piece is provided and fixed to the joist, the attachment strength of the end connecting fitting 3A to the joist 1 is ensured.

  The curved locking piece 33 includes a rising portion 33a that rises from the upper surface portion 31, a protruding portion 33b that protrudes horizontally from the upper end of the rising portion, and a downward protruding portion that is curved so as to protrude downward from the tip of the protruding portion. 33c and an inclined portion 33d that inclines upward from the lower convex portion are integrally provided. The height from the horizontal plane passing through the upper surface portion 31 to the downward convex portion 33 c is set to be slightly smaller than the thickness of the tip of the protrusion 21 of the deck material 2. The inclined portion 33d is provided with a plurality of screw through holes 33h that are separated from each other in the longitudinal direction of the upper surface portion 31. The reason why the inclined portion 33d is provided with the screw through hole is to facilitate screwing the screw into the screw through hole from the side of the deck material, as will be described later.

  On the other hand, among the connection fittings improved in the present invention, the intermediate connection fitting 3B rises from both sides of the strip-shaped bottom 34 as shown in FIG. It has the stop piece 35 integrally. The bottom portion 34 has a length substantially equal to the width of the upper surface of the joist 1, and a screw through hole 34h is provided at the center in a position separated in the longitudinal direction. The curved locking pieces 35 on both sides are formed symmetrically, and each curved locking piece 35 has the same shape and size as the curved locking pieces 33 of the end connecting fitting 3A described above. That is, one of them will be described. A rising portion 35a rising from the bottom portion 34, a protruding portion 35b protruding horizontally from each rising portion 35a in opposite directions, and a convex surface downward from the tip of the protruding portion. The lower convex portion 35c and the inclined portion 35d that inclines upward from the lower convex portion are integrally provided. Further, the height from the horizontal plane passing through the bottom 34 to the downward projection 35c is set to be slightly smaller than the thickness of the tip of the ridge of the deck material. Further, at least one of the two inclined portions 35 d is provided with a plurality of screw through holes 35 h that are spaced apart in the longitudinal direction of the bottom portion 34.

  The deck material 2 in FIG. 1 has ridges 21 on both sides as in the prior art, and preferably has a thickness so that the tips of the ridges are not easily released from the connection fittings. It is formed in meat.

  A process of attaching such a deck material to the joists 1 using the connecting fittings 3A and 3b will be described subsequently. As shown in FIG. 4, first, the end connection fitting 3 </ b> A is fixed to the upper surface of the end of the joist 1. That is, the hanging pieces 32 on both sides are brought into contact with both side surfaces of the joists 1, the upper surface portion 31 is placed on the upper surface of the joists, and the respective hanging pieces 32 and / or the upper surface portions 31 are fixed to the joists 1 with screws b1 and b2. At that time, a gap slightly thinner than the thickness of the thick portion at the tip of the protrusion 21 of the deck material 2 is formed between the downward convex portion of the curved locking piece 33 of the end connection fitting and the upper surface of the joist 1. Has been.

  Then, the starting end deck material 2 s is placed on the joist 1 in a state perpendicular to the longitudinal direction of the joist and is pressed in the direction of the end connecting bracket 3 </ b> A. At that time, the ridge 21 at the tip of the start deck material pushes up the lower convex portion 33c of the curved locking piece 33 of the end connecting bracket 3A against its elasticity, and between the lower convex portion and the upper surface of the joist. Since the curved locking piece 33 is restored by elasticity, the protrusion of the start deck is hooked and locked by the curved locking piece.

  Next, as shown in FIG. 5, the intermediate coupling fitting 3B is placed on the top surface of the joist 1 at the other end of the joist of the starting deck material 2s, and the curved locking piece 35 having a screw through hole 35h is formed thereon. It hooks on the protrusion 21 on the other end side of the joist of the starting deck material 2s, and the inclined portion 35d of the curved locking piece 35 is fitted into the concave portion on the side surface of the deck material 2s. The screw b3 is screwed into the joist 1 from 34h to fix the intermediate connecting fitting 3B to the joist 1, and the screw b4 is screwed into the starting end deck material 2s from the screw through hole 35h provided in the inclined portion 35d of the intermediate connecting fitting 3B. . Thus, the start deck material 2s is fixed to the joist 1 so as not to move in the width direction and the longitudinal direction.

  As shown in FIG. 1, the intermediate deck material 2m, which is the deck material to be mounted second, has a rib 21 on one end side of the joist, and a protrusion on one end side of the joist deck material 2s. In the same manner that the curved locking piece 33 and the joist 1 are pushed and fixed, the curved latching piece 35 is pushed into the curving locking piece 35 on the other side of the joist 1 of the intermediate coupling fitting 3B. It hooks and locks on the ridge of the deck material 2m. Then, the next intermediate connecting fitting (not shown) is fixed to the upper surface of the other side of the second intermediate deck member in the same manner as in the case of the first intermediate connecting fitting 3B to form a screw through hole 35h. The curved locking piece 35 is hooked on the protrusion 21 on the other end side of the intermediate deck material 2m, and the inclined portion 35d of the curved locking piece 35 is fitted into the concave portion on the side surface of the deck material 2s. In this state, the screw b3 is screwed into the joist 1 from the screw through hole 34h of the bottom 34 to fix the intermediate connecting fitting 3B to the joist 1, and the screw from the screw through hole 35h provided in the inclined portion 35d of the intermediate connecting fitting 3B. Screw b4 into the intermediate deck material 2m. Thereby, the intermediate deck material 2m is fixed to the joist 1 so as not to move in the width direction and the longitudinal direction.

  Thereafter, up to the intermediate deck material 2m immediately before the end deck material 2e, the curved engagement piece and the joist of the intermediate coupling metal for fixing the deck material (the first-order deck material) attached in the previous order, respectively, in the same manner as described above. 1. Pushing the protrusion on one end side of the rear deck material into the upper surface of 1, attaching the rear intermediate connection fitting to the upper surface of the joist on the other side of the intermediate deck material, and one end side of the connection fitting By repeatedly screwing the curved locking piece into the deck material, the deck material can be sequentially fixed to the joist.

  Then, in order to fix the end deck material 3e to the joist, as shown in FIG. 6, a protrusion on one end side of the joist of the end deck material is provided between the curved locking piece of the last intermediate coupling fitting and the upper surface of the joist. Then, on the other side of the end deck material, another end connection fitting 3A is placed on the upper surface of the joist with the curved locking piece 33 facing the end deck material side, The locking piece 33 is hooked and locked to the ridge 21 of the deck material, and a screw is screwed into the joist from the upper surface portion 31 and / or the hanging piece 32, and at this time, the curved locking piece 33 is fixed to the terminal deck. The concave portion on the other side of the material is fitted, and a screw from the inclined portion is screwed into the protrusion 21 to fix the terminal deck material to the joist 1.

  Although the example in the case where the longitudinal direction intermediate part of each deck material is fixed to joist has been described and explained above, the mounting structure according to the present invention is the longitudinal direction of the deck material 2 as shown in FIGS. It can also be used when the direction ends are fixed on the joists 1 adjacent to each other. Explaining this, as shown in FIGS. 7 and 8, the attachment form of the end connection fitting 3 </ b> A and the intermediate connection fitting 3 </ b> B to the joist is not different from the case where the longitudinal intermediate portion of the deck material is fixed to the joist. The deck materials adjacent in the longitudinal direction are placed on the common joists 1 at their adjacent ends, and are coupled to the joists 1 via the common end fittings 3A or intermediate fittings 3B, respectively.
