Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 7 show one embodiment of a framed deck according to the present invention. As shown in Figures 4 to 6, this framed deck has a cubic frame structure 15 installed on a deck 14 installed along an exterior wall 13 in the garden of a house.
The frame structure 15 is composed of four pillars (frames) 3 erected at intervals in the front-rear and left-right directions, and four beams (frames) 9 installed between the upper ends of the pillars 3. Hooks 16 are attached to the beams 9 as shown in Fig. 1, and a sheet-like sunshade 17 is attached by hanging it on the hooks 16. The sunshade 17 covers the opening surrounded by the beams 9 as shown in Fig. 6, thereby providing shade on the deck 14.

As shown in Figures 4 to 6, the deck 14 has a number of joists (deck material support materials) 18 supported by beams 19 and installed in the left-right direction at intervals in the front-to-back direction, with deck materials 1, 1, ... mounted side-by-side in the left-right direction on the joists 18, and a fascia board 20 attached to three edges excluding the exterior wall 13 side, with the fascia board 20 hiding the end faces and side faces of the deck material 1 and the joists 18.
The deck material 1 is made by extrusion molding synthetic resin mixed with wood powder, and as shown in Figure 1, it is formed into a plate shape with a hollow portion, with upper engagement portion 7 and lower engagement portion 8 protruding laterally from both edge portions. The deck materials 1 are arranged with gaps 53 in the left-right direction, and the deck material fixing brackets 2 arranged in the gaps 53 between the deck materials 1 are engaged with the lower engagement portion 8 and screwed to the rails 18 from above with screws 21, thereby pressing the deck materials 1 downward and fixing them to the rails 18.

7, the pillar 3 is formed of a hollow aluminum material having a substantially square cross section. The pillar 3 has tapping holes 23 at each corner.
A pillar fixing bracket (frame fixing bracket) 5 is provided at the lower end of the pillar 3. The pillar fixing bracket 5 is composed of a stainless steel square plate 25 and a cylindrical portion 26 formed of an aluminum shaped material and having a cross section slightly smaller than that of the pillar 3, and is integrated by screwing screws 27 inserted from below into the four corners of the plate 25 into tapping holes 28 formed in the cylindrical portion 26. As shown in Figures 2 and 7, the plate 25 has an outer shape the same as that of the pillar 3, and is formed with screw insertion holes 29 through which screws 22 for fixing the pillar fixing bracket 5 to the deck 14 are inserted, and a water drainage hole 30. The peripheral portion of the plate 25 of the pillar fixing bracket 5 protrudes from the cylindrical portion 26 to form a flange 58.
Then, as shown in Figure 1, the column fixing bracket 5 is placed on the deck material 1, and a screw 22 is inserted from above into the screw insertion hole 29 (see Figure 7) and threaded through the deck material 1 into the joist 18, thereby fixing the column fixing bracket 5 to the deck 14. Then, the lower end of the column 3 is fitted around the tubular portion 26, the lower end surface of the column 3 is placed on the flange 58, and the column 3 and the tubular portion 26 are fixed from the side by the screw 32. In this way, the column 3 is fixed to the joist 18. The column 3 can be installed at any position on the joist 18 in the longitudinal direction.

As shown in FIG. 1, the beam 9 is made of aluminum material and is formed into a cylindrical shape with a roughly rectangular cross section. A column-beam connector 10 is attached to the side of the upper end of the column 3. The column-beam connector 10 is formed by bending a metal plate into a U-shape, and has an upper wall 39, a lower wall 40, and a vertical wall 41. The vertical wall 41 abuts against the side of the column 3 and is fixed with a screw 42. The upper wall 39 abuts against the lower surface of the upper wall 43 of the beam 9 and is fixed with a screw 44 from above, and the lower wall 40 abuts against the lower surface of the lower wall 45 of the beam 9 and is fixed with a screw 46 from below. The beam 9 has a groove 47 formed on its lower surface along the longitudinal direction, and a batten 48 is engaged and attached to the groove 47 from below to hide the column-beam connector 10.

As shown in Figures 1 and 3, a column end cap 11 made of a stainless steel plate is attached to the upper end of the column 3 to close the end of the column 3. The column end cap 11 is fixed to the end face of the column 3 with a screw 49 that is screwed into the tapping hole 23 of the column 3. The column end cap 11 has an extension 12 that abuts the upper surfaces of the two beams 9 that are connected to the column 3 and extends toward the beams 9. The extension 12 is fixed to the column beam connector 10 together with the beam 9 with a screw 44 that is screwed into the upper wall 39 of the column beam connector 10, and is further fixed to the upper wall 43 of the beam 9 with a screw 50 from above.

As shown in Figure 14(a), if there is no column end cap 11, when a lateral load acts on the frame structure 15 due to earthquake shaking, strong winds, or a person leaning on the column 3, a gap 51 will be created between the upper end of the beam 9 and the column 3 (part a in the figure) and between the lower end of the beam 9 and the column 3 (part b in the figure), as shown in Figures 14(b) and 14(c), and as a result, the frame structure 15 will shake.
In contrast, with this framed deck, as shown in Figure 13(a), a column end cap 11 is attached to the upper end of the column 3 to close the end of the column 3, and the extension portion 12 of the column end cap 11 is abutted against the upper surface of the beam 9 and fixed to the beam 9.As a result, even if a lateral load acts on the frame structure 15 due to earthquake shaking, strong winds, or a person leaning on the column 3, as shown in Figures 13(b) and (c), no gaps are created between the upper end of the beam 9 and the column 3 (part a in the figure) or between the lower end of the beam 9 and the column 3 (part b in the figure), which has the effect of suppressing the shaking of the frame structure 15.

11 and 12 show another embodiment of the framed deck of the present invention. In this framed deck, the columns 3 are disposed at positions offset from above the beams 18.
A reinforcing member 55 (deck material support member) is installed between the joists 18. As shown in Fig. 12, the reinforcing member 55 is made of a hollow aluminum material, placed on the upper surface of the part that protrudes to the side of the lower side of the joists 18 (see Fig. 5), both ends of which in the longitudinal direction are formed into a convex cross section, and fixed with screws 56 from above. The column fixing bracket 5 is fixed to the reinforcing member 55 with screws 22 from above.
By appropriately installing the reinforcing members 55 between the beams 18 in this manner, the columns 3 can be erected anywhere on the deck 14.

Next, the construction procedure for this framed deck will be described. First, the studs 19 are installed in the prescribed positions, and the beams 18 are erected on the studs 19. In addition, reinforcing members 55 are erected between the beams 18 as necessary.
Next, the deck materials 1, 1, ... are attached in order from one side onto the joists 18. After that, the fascia board 20 is attached.
After the construction of the deck 14 is completed, the frame structure 15 is constructed on the deck 14. To construct the frame structure 15, first, as shown in Fig. 8-1(a), four pillar fixing brackets 5, each having a plate 25 and a cylindrical portion 26 integrated therewith, are temporarily placed at the positions on the deck 14 where the pillars 3 are to be erected.
8-1(b) and 9 and 10, the pillar fixing bracket 5 is positioned by arranging the four beams 9 between the plates 25 of the pillar fixing bracket 5 with the ends of the beams 9 butting against the plates 25 of the pillar fixing bracket 5. As mentioned above, since the outer shape of the plates 25 of the pillar fixing bracket 5 matches the outer shape of the column 3, simply arranging the beams 9 between the pillar fixing brackets 5 in this way makes it possible to accurately position the four pillar fixing brackets 5 at the specified column positions.
Next, as shown in Figure 8-1 (c), a screw hole for the screw 22 is drilled with a drill 57 in accordance with the position of the screw insertion hole 29 (see Figure 7) of the plate 25 of the pillar fixing bracket 5. The screw hole may be drilled by inserting the drill 57 into the screw insertion hole 29 of the plate 25 after fixing the plate 25 to the deck material 1 with adhesive tape or the like to prevent it from shifting, or by marking the position of the screw insertion hole 29 on the deck material 1 with a scriber or the like and temporarily shifting the pillar fixing bracket 5.
Next, as shown in FIG. 8-2(d), the column fixing bracket 5 is fixed to the beam 18 or the reinforcing material 55 from above with the screw 22.
Next, after first attaching the column-beam connector 10 to the side surface of the upper end of the column 3, the lower end of the column 3 is fitted from above into the tubular portion 26 of the column fixing bracket 5, and the lower end surface of the column 3 is placed on the flange 58, as shown in Figure 8-2 (e).
Next, as shown in FIG. 8-2(f), the column 3 and the cylindrical portion 26 of the column fixing bracket 5 are fixed from the side with a screw 32.
Thereafter, the column-beam connector 10 attached to the column 3 is inserted into the end of the beam 9 and fixed to the beam 9, thereby erecting the beam 9 between the columns 3.
Then, a column end cap 11 is attached to the upper end of the column 3, the column end cap 11 seals the upper end of the column 3, and the extension portion 12 of the column end cap 11 is fixed to the upper surface of the beam 9 to connect the column 3 and the beam 9.

As described above, this framed deck comprises deck materials 1, 1, ..., deck material supports (joists 18, reinforcements 55) which support the deck materials 1, 1, ..., frames (pillars) 3 mounted on the deck materials 1, 1, ..., and frame fixing brackets (pillar fixing brackets) 5 mounted on the lower end of the frame 3, and the frame fixing bracket 5 has a plate 25 placed on the deck material 1 and a tubular portion 26 which is placed within the hollow portion of the frame 3, and the plate 25 is fixed to the deck material supports 18, 55 with screws 22 from above, and the tubular portion 26 is fixed to the frame 3 with screws 32 from the side, allowing the frame 3 to be attached anywhere on the deck 14.
The plate 25 of the frame fixing metal fitting 5 has a flange 58 protruding from the periphery of the cylindrical part 26, and the lower end of the frame 3 is placed on the flange 58, so that the edge of the frame 3 can be covered with the plate 25 and the frame 3 can be stably supported.
The deck material support has joists 18 and reinforcing members 55 installed between the joists 18, and the plate 25 of the frame fixing metal fitting 5 is fixed to the joists 18 or the reinforcing members 55 with screws 22, so that the frame 3 can be stably installed at any position on the deck 14.
The frame fixing bracket 5 has a plate 25 made from a stainless steel plate, a cylindrical portion 26 made from an aluminum profile and has a tapping hole 28, with the plate 25 and cylindrical portion 26 being integrated together by a screw 27 which is screwed into the tapping hole 28 from below and the inside of the cylindrical portion 26 being screwed to the deck material supports 18, 55.As such, it has excellent strength, durability and weather resistance, can be manufactured inexpensively and can firmly fix the frame 3 to the deck material supports 18, 55.
The plate 25 of the frame fixing metal fitting 5 is provided with a hole (drainage hole) 30 penetrating in the vertical direction, so that rainwater that has entered the frame 3 can be drained.

The manufacturing method of this frame structure 15 includes vertical members (columns) 3, horizontal members (beams) 9 installed between the vertical members 3, and vertical member fixing brackets (column fixing brackets) 5 that fix the lower ends of the vertical members 3 to the base (deck) 14. The vertical member fixing brackets 5 have plates 25 whose outer shape matches that of the vertical members 3. The vertical member fixing brackets 5 are positioned by placing the horizontal members 9 between the plates 25 and then fixed to the base 14. The vertical members 3 are erected on the plates 25 of the fixed vertical member fixing brackets 5, and the horizontal members 9 are installed between the vertical members 3, which makes the method easy to construct. In other words, simply by placing the horizontal members 9 between the plates 25, the spacing and orientation of the vertical members 3 can be accurately determined, and since there is no need to take the time to measure the spacing with a general-purpose scale, the frame structure 15 can be accurately assembled in a short time.

In addition, this frame structure 15 comprises a column 3, a beam 9, a column-beam connector 10, and a column end cap 11. The column-beam connector 10 is fixed to the side of the column 3 and inserted into the end of the beam 9 and fixed to the beam 9. The column end cap 11 covers the end of the column 3 and has an extension portion 12 extending toward the beam 9. The extension portion 12 is fixed to the beam 9 by abutting against the upper surface of the beam 9, resulting in a neat and attractive design and preventing gaps from opening between the columns and beams, thereby firmly connecting the column 3 and the beam 9.
Since the extension portion 12 is fixed to the column-beam connector 10, the extension portion 12 can be firmly fixed to the beam 9.
The column-beam connector 10 is fixed to the beam 9 from below with a screw 46, and the column end cap 11 is fixed to the beam 9 from above with screws 44, 50, so that gaps are prevented on both the upper and lower ends of the joint surfaces between the column 3 and the beam 9, which is highly effective in suppressing the swaying of the simple structure 15.
The column 3 has a tapping hole 23, and the column end cap 11 is fixed to the column 3 by a screw 49 that is screwed into the tapping hole 23 of the column 3, so that the column end cap 11 can be easily and reliably fixed to the column 3.
Since the column end cap 11 is made of metal, it has high strength even in the form of a thin plate, and is able to reliably suppress the shaking of the simple structure 15 while maintaining a simple design.

The present invention is not limited to the embodiments described above. The configuration and use of the frame can be changed as appropriate, and for example, it can have one pillar for mounting lighting, or six pillars instead of four as in the embodiments, or multiple pillars arranged in a straight line with cross members erected on or between the pillars to form a fence, or a bottom frame can be attached to the lower part between the pillars. The material and shape of the frame fixing fittings can be changed as appropriate.
