(Deck composition)
The deck of this embodiment is a deck that is placed close to the exterior wall of a building and can be used through an opening in the building, and as shown in Figures 1 and 2(a), it has a plurality of (four) pillars 1, a plurality of (two) joists 2 installed across the upper ends of the pillars 1, and a plurality of (six) rows of deck material 3. Note that the numbers of pillars 1, joists 2, and rows of deck material 3 are not limited.

The deck has an inspection hatch in the center, and comprises long deck materials 30, 31, 38, 39 arranged in two outer rows in the viewing direction, and two central rows of central deck materials in which the inspection hatch is provided, and the central deck materials are made up of rear deck materials 32, 33, central deck materials 34, 35, and front deck materials 36, 37.
The deck has an inspection hatch cover 5 that covers the inspection hatch formed by central deck materials 34, 35 that constitute the central deck material.

The pillar 1 is a long, hollow member made of a metal material such as aluminum alloy, with a rectangular cross section, and is fixed to the top surface of the foundation or the like using fixing brackets or the like.

The joist 2 is made of a metal material such as aluminum alloy, and is a long, hollow, convex member with a cross section that is narrower at the top and wider at the bottom. It is placed on the top end of the column 1 and fixed in place with screws, etc.

The deck material 3 is made of a metal material such as an aluminum alloy, and as shown in Figure 7(a), it has an upper wall 3a, a bottom wall 3b, and multiple partition walls 3c, 3c that separate the upper wall 3a and the bottom wall 3b, and is a member with a hollow cross-section in which multiple hollow portions 3d extending in the longitudinal direction (front-to-back direction) are lined up in the left-to-right direction.
The deck material 3 has a bottom wall 3b that extends to the left and right and protrudes outward beyond the partition walls 3c at the left and right ends, and these protruding portions form connecting portions 3e for connecting and fixing the deck material 3.

Of the deck materials 3 arranged in multiple rows, the deck materials 30, 31, 38, and 39 arranged in the two outer rows in the facing direction are arranged across the joists 2, 2 lined up in front and behind, as shown in Figures 1 to 3, and are fixed to the joists 2 with deck material mounting brackets 25.

In the area including the two central rows, the joists 2 are secured to the front and rear of the deck material support brackets 21, 22, made of metal such as steel and having a roughly L-shaped cross section, by bolts (fixing means) b1. As shown in Figures 2 and 3, the rear deck materials 32, 33 and the front deck materials 36, 37 are supported by the top surfaces of the joists 2 and the front and rear deck material support brackets 21, 22, and secured by deck material mounting brackets 25.

Of the deck material support fittings 21, 22, the deck material support fitting 22 fixed to the inspection hatch side extends further toward the inspection hatch than the rear ends of the front deck materials 36, 37 (and the front ends of the rear deck materials 32, 33), as shown in Figure 2(b), and is formed with a support portion 22a on which the front and rear edges of the inspection hatch cover 5 can be placed.

As shown in Figures 2(b) and 4(b), the deck material support fitting 22 has guide blocks 26, 26 fixed to the top surface of the mounting portion 22a on both sides of the inspection hatch cover 5 in the viewing direction, and cushioning material 27 is arranged on the mounting portion 22a to absorb impact when the inspection hatch cover 5 is placed, thereby reducing impact when the inspection hatch cover 5 is closed.

The deck has a resin edge member 6 attached to its outer periphery, and the end openings and side surfaces of the deck material are not exposed, resulting in a deck with excellent design.
The inspection hatch cover 5 is provided with a rotating handle 51 that rotates around a horizontal axis and appears and disappears, and inspection of the area below the deck can be performed by extending the rotating handle 51 and lifting and opening the inspection hatch cover 5.

(Inspection hatch cover)
As shown in Figures 2(b), 4(b), 5 and 6, the inspection hatch cover 5 of this embodiment has central deck materials 34, 35 lined up on the left and right, and cross members 52, 52 arranged on the underside of the central deck materials 34, 35 and connecting the central deck materials 34, 35, and a rotating handle 51 is arranged within the hollow portion 3d of one of the central deck materials 35.

The cross member 52 is made of a metal material such as aluminum alloy, has a hollow rectangular cross section, and is a long member slightly shorter in length than the visible dimension of the central deck materials 34, 35 when lined up, with resin end caps attached to both ends.

As shown in Figures 2, 5 and 6, the inspection hatch cover 5 is formed by placing central deck members 34, 35 on the top surfaces of two horizontal members 52, 52 arranged in the front-to-rear direction, and fastening the horizontal members 52, 52 to a back plate member 53 with a U-shaped cross section that is placed within the hollow portion 3d of the central deck members 34, 35 with bolts (fixing means) b2.

As shown in FIG. 6( c ), the inspection hatch cover 5 has a reinforcing member 8 disposed within the hollow portion 3 d in which the rotary handle 51 of the central deck material 35 is disposed.
As shown in Figure 6 (d), the reinforcing member 8 comprises an upper reinforcing member 81 which is approximately U-shaped in cross section and opens downwards and is placed within the hollow portion 3d of the deck material 3; a lower reinforcing member 82 which is approximately U-shaped in cross section and opens upwards and is placed within the hollow portion 3d of the deck material 3; and an extension member 83 which is made of a bolt or the like which is screwed to the underside of the deck material 3 using the lower reinforcing member 82 within the hollow portion 3d as a backing plate and whose upper end abuts the underside of the inner periphery of the upper reinforcing member 81.

The upper reinforcement member 81 and the lower reinforcement member 82 have the same cross-sectional shape, consisting of bottom walls 81a, 82a and left and right side walls 81b, 82b extending from both sides of the bottom walls 81a, 82a, and are arranged within the hollow portion 3d so that the side walls 81b, 82b are staggered with their openings facing each other.

As shown in Figures 8(a) to (c), the rotating handle 51 has a handle body 51a, a retaining wall 51b that rotatably holds the handle body 51a, and a rim portion 51c provided around the retaining wall 51b.

As shown in Figures 8(d) and (e), the central deck material 35 to which the rotating handle 51 is attached has an opening 35a formed at the attachment site of the rotating handle 51 on the upper wall 3a, which is large enough to insert the handle body 51a and retaining wall 51b of the rotating handle 51. A recess 35b is formed around the opening 35a to accommodate the edge portion 51c of the rotating handle 51, and screw holes 35c, 35c are formed at appropriate positions in the recess 35b.

As shown in Figures 8(f) to (i), the upper reinforcement member 81 has a cutout 81c formed by cutting out portions of the bottom wall 81a and side wall 81b, and is positioned within the hollow portion 3d so that the opening 35a formed in the central deck material 35 and the cutout 81c are aligned.

As shown in Figures 9(a) and (b), the rotating handle 51 has the handle body 51a and retaining wall 51b inserted into the hollow portion 3d through the opening 35a in the upper wall 3a of the central deck material 35 and the cutout portion 81c in the upper reinforcement material 81, and the edge portion 51c is placed in the recess 35b and fixed to the central deck material 35 and the upper reinforcement material 81 with screws (fixing means) b or the like.
As shown in Figure 9 (c), the rotating handle 51 attached to the central deck material 35 can be grasped by rotating the handle body 51a around the axis 51d of the retaining wall 51b, causing the handle body 51a to protrude above the central deck material 35.

The reinforcing member 8 is attached to the underside of the central deck material 35 by a bolt (expansion member) 83 which is screwed into the lower reinforcing member 82 as a backing plate and comes into contact with the bottom wall 82a of the upper reinforcing member 81, causing the upper end of the bolt (expansion member) 83 to push up the upper reinforcing member 81 and widen the gap between the bottom wall 81a of the upper reinforcing member 81 and the bottom wall 82a of the lower reinforcing member 82.
The reinforcing member 8 has an expanded gap between the bottom wall 81a of the upper reinforcing member 81 and the bottom wall 82a of the lower reinforcing member 82, which abut against the upper and lower inner surfaces of the hollow portion 3d, respectively, reinforcing the hollow portion 3d in which the rotating handle 51 is located from the inside.

The lower reinforcement 82 placed within the hollow portion 3d also serves as the backing plate member 53 for fixing the cross member 52 to the central deck material 35, and as shown in Figure 6(a), the lower reinforcement 82 and the cross member 52 are fixed with bolts (fixing means) b2.

(Edge covering material)
In the deck of this embodiment, edge concealing materials 7 are attached to the areas where the front-to-rear end faces (edges) of the deck material 3 face each other, specifically, to the front and rear end faces (edges) of the central deck materials 34, 35 that make up the inspection hatch cover 5 shown in Figure 4(b), and to the front end faces of the rear deck materials 32, 33 (or the rear end faces of the front deck materials 36, 37) shown in Figure 3(b).

The edge covering material 7 is made from a flat metal plate and, as shown in Figures 7(b) and (c), has a vertical plate-shaped covered portion 7a, an upper wall portion 7b formed by bending the upper edge of the covered portion 7a in one direction, and left and right fixing pieces 7c, 7c formed by bending the sides of the covered portion 7a in one direction, with screw holes 7d formed in the left and right fixing pieces 7c.

As shown in Figures 7(d) and (e), the edge concealing material 7 is arranged such that the concealing portion 7a covers the edge of the deck material 3, the upper wall portion 7b is placed on the upper wall 3a of the deck material 3, and the left and right fixing pieces 7c, 7c are abutted from the outside against the partition walls 3c, 3c at both ends of the deck material 3 in the view direction, and is attached to the deck material 3 by screwing a screw (fixing means) b3 through the screw hole 7d in the fixing piece 7c.
In addition, the fixing position of the fixing piece 7c of the edge covering material 7 relative to the deck material 3 is not limited to the partition walls 3c, 3c, and the shape of the fixing piece 7c may be changed so that it is fixed to another part of the deck material 3.

When a deck material 3 has edge concealment material 7 attached, the upper part of the edge is covered by the concealed portion 7a of the edge concealment material 7, and the lower part of the edge is exposed.

(Effects of the deck of this embodiment)
The deck of this embodiment is constructed by placing U-shaped reinforcing members with their openings facing each other within the hollow portion of the deck material and reinforcing the hollow portion by expanding them with bolt members. This allows for simple construction to improve the strength of the handle that is gripped when opening and closing the inspection hatch cover, preventing damage to the handle when opening and closing the inspection hatch cover and improving the overall strength. It is also less likely to break when a person stands on the inspection hatch.

In the deck of this embodiment, the reinforcing members placed within the hollow portion of the deck material are formed with U-shaped cross-sections, with the openings facing each other. This means that each reinforcing member is more stable within the hollow portion of the deck material than flat reinforcing members, and the deck material can be reinforced without tilting within the hollow portion due to external forces from the bolt members.

The deck of this embodiment can prevent rainwater and debris from entering the hollow portion of the deck material through simple construction by sealing the end faces of the deck material that makes up the inspection hatch cover and the end faces of other deck materials that face the end faces with edge sealing material.
In addition, by sealing only the upper part of the hollow portion of the deck material with edge sealing material and leaving the lower part exposed, rainwater and other water that has seeped into the hollow portion of the deck material can be drained, preventing the deck from becoming dirty or corroded and improving its weather resistance.

In the deck of this embodiment, the closing portion of the end closing material that closes the end face of the deck is formed from a flat metal plate, which allows the deck material to be formed inexpensively, and the simple structure of the closing material makes installation easy.
Furthermore, it is possible to prevent debris from entering through the end face of the deck material at the inspection hatch and improve the design without increasing the distance between the end face of the deck material that constitutes the inspection hatch cover and the end face of the deck material opposite to that end face.

In addition, the hollow portion of the deck material reinforced by the reinforcing member is not limited to the hollow portion where the rotating handle is located, and other hollow portions may also be reinforced with similar reinforcing members as necessary.
Furthermore, the deck material that constitutes the deck is not limited to deck material supported by joists.
It goes without saying that the above embodiments do not limit the invention described in the claims, but are to be treated as examples.
