[0012] (First embodiment) An embodiment of a deck structure using the headboard fastener of the present invention will be described in detail below with reference to the drawings. Fig. 1 is an overall perspective view showing a deck structure to which the headboard fastener of the first embodiment is applied. Fig. 2 is an exploded perspective view of the deck structure shown in Fig. 1. Fig. 3 is a front view, with a portion thereof cut away, of the deck structure shown in Fig. 1. Fig. 4 is an enlarged view of a main portion of Fig. 3. Fig. 5 is a side view, with a portion thereof cut away, of the deck structure shown in Fig. 1. Fig. 6 is an enlarged view of a main portion of Fig. 5.

[0013] The deck structure 100 comprises a plurality of support members 10 arranged side by side on the installation surface, joists 20 spanning between the support members 10, floorboards 30 arranged side by side on the joists 20 to form a floor surface 35, a fascia board 40 installed to surround the periphery of the floor surface, and a fascia board fixing device 50 for fixing the fascia board 40. The deck structure 100 may be configured such that a frame member called a joist is further provided between the joists 20 and the support members 10, extending in a direction intersecting the joists 20.

[0014] The support members 10 are columnar bases arranged in a row on an installation surface such as the ground, and are arranged in a row to match the size and shape of the floor surface formed by the deck structure 100. In this embodiment, in which a rectangular floor surface is formed, three support members 10 are arranged in a row in the extension direction of the joists 20 as shown in Fig. 2, and three support members 10 are arranged in a row in the extension direction of the floorboards 30 as shown in Fig. 5. The lower end of the support member 10 may be buried and fixed to the installation surface side, or may be fixed with a bolt using an L-shaped fixing member or the like. The upper end of the support member 10 is attached and fixed to the lower surface of the floor joist 20.

[0015] The support member 10 need only be configured to support the joists 20, and is not limited to the columnar member of this embodiment. For example, the support member 10 may be provided with a height adjustment mechanism to change the height, thereby making it possible to adjust the height position at which the floor surface 35 is formed. As a specific example, the support member 10 may be provided with a threaded groove (not shown) formed on the outer circumferential surface along the vertical direction, and an intermediate support (not shown) that engages with the threaded groove. With this configuration, the overall height of the support member 10 can be continuously and finely adjusted by adjusting the tightening amount of the intermediate support. Note that the configuration for adjusting the height of the support member 10 is not limited to the above, and the support member 10 and the intermediate support may be fixed with pins to adjust the height discontinuously. This means that even if the installation surface on which the deck structure 100 is installed has a staircase-like step, a slope-like inclined surface, a recess due to a drainage groove, or a protrusion due to a beam, the floor surface 35 can be kept level by appropriately adjusting the height of the support member 10.

[0016] The joists 20 are frame members installed to bridge the upper ends of the support members 10, and are formed in the shape of hollow square pillars, thereby having holes 20a along the extension direction. As shown in Figure 2, multiple joists 20 are arranged in parallel at predetermined intervals. Adjacent joists 20 may be connected to each other by frame-shaped connecting members 25 that connect them to each other.

[0017] 6, the joist 20 is a cylindrical frame member whose entire cross section is formed into a rectangular shape with a convex portion, and has a pair of retaining plates 21, 21 protruding downward from both ends of the width direction of the lower surface, a pair of first step portions 22 bent in a crank shape from the middle of the vertical direction of both side surfaces in a direction narrowing the width toward the top, and a pair of second step portions 23 bent in a crank shape above the first step portions 22 in a direction further narrowing the width. As a result, the first step portions 22 give the joist 20 a convex shape in its entire cross section, and the second step portions 23 form grooves on both sides of the top surface of the joist 20. The floor joist 20 has a floorboard 30 placed on its upper surface, which is narrowed by the groove-shaped second step portion 23.

[0018] As shown in FIGS. 3 to 6, the pair of holding plates 21 are attached to the outer peripheral surfaces of the upper ends of the pair of support members 10. The support members 10 are held by sandwiching them together, and are fixed to the support member 10 side by fixing screws 26 or the like that are inserted horizontally. This fixes the support member 10 and the joist 20. The fixing screws 26 may be replaced with other fixing means such as nails or rivets.

[0019] It should be noted that the method of fixing the joist 20 to the upper end of the support member 10 is not limited to the configuration using the pair of holding plates 21 and fixing screws 26 as in the example shown in FIG. 17 is a diagram showing another embodiment of the support member and joist. The joist 20 has a flat bottom surface formed by eliminating the above-mentioned holding plate 21. The support member 10 has a support plate 11 at its upper end on which the joist 20 is placed. According to this configuration, the upper end of the support member 10 and the joist 20 can be fixed by passing a fixing screw 13 or the like through the underside of the joist 20 from the underside of the support plate 11 on which the joist 20 is placed to the underside of the joist 20. According to this configuration, by using steel material or the like for the support member 10, even if the support member 10 is thinner than the joist 20, the joist 20 can be fixed stably to the upper end of the support member 10.

[0020] Furthermore, as shown in Figure 18, a configuration may be adopted in which a pair of fixing plates 15 are provided on a support plate 11 provided at the upper end of the support member 10 and attached to the side surfaces of joists 20 placed on the support plate 11. Each fixing plate 15 is bent into an L-shape in plan view, and has a first portion 15a that contacts the thin joist 20A and a second portion 15b that contacts the thick joist 20B. Furthermore, the pair of fixing plates 15 are arranged such that the first portions 15a and the second portions 15b are positioned relative to each other, and the distance between the second portions 15b is wider than the distance between the first portions 15a. According to this configuration, the joists 20 can be fixed to the upper ends of the support members 10 by fixing the side surfaces of the joists 20 placed on the support plates 11 to the pair of fixing plates 15 with fixing screws or the like. In addition, by appropriately adjusting the angle of the side portions of the fixing plates 15 that abut against the joists 20, joists 20 of various thicknesses can be attached and fixed, thereby increasing versatility. Each fixing plate 15 may be configured to curve in a direction away from the other fixing plate 15 toward its tip in a plan view. This configuration is preferable because it allows some leeway in the thickness of the joists 20 that can come into contact between the pair of fixing plates 15, thereby further improving versatility.

[0021] As shown in Figures 3 and 5, connecting members 25 that connect the joists 20 arranged in parallel are fixed to the pair of first step portions 22. Specifically, the connecting members 25 are elongated plate-like members with a U-shaped cross section that is open at the bottom, and have flange portions that are bent horizontally outward at both widthwise ends, and are fixed to the first step portions 22 by fixing screws 27 or the like with the flange portions placed on the first step portions 22. The fixing screws 27 may be replaced with other fixing means such as nails or rivets.

[0022] 4 and 6, a pair of second step portions 23 are fixed to the fascia board fixing devices 50 inserted into the holes 20a of the floor joists 20 via fixing screws 28 or the like. The heads of the fixing screws 28 are positioned in the vertical gaps formed between the second step portions 23 and the upper surfaces of the floor joists 20. This allows the header board fastener 50 inserted into the hole 20a of the floor joist 20 to be easily fixed from the top side of the floor joist 20 using the fixing screw 28, and also prevents the fixing screw 28 from interfering with the floorboard 30 placed on the top surface of the floor joist 20. The fixing screw 28 may be replaced with other fixing means such as a nail or a rivet.

[0023] The floorboards 30 are longitudinal plate-like members that are arranged to intersect or intersect perpendicularly with the joists 20, and by arranging multiple boards in a row along the extension direction of the joists 20, they form a floor surface 35 that serves as the deck floor. As shown in Figure 5, the floorboard 30 has an uneven surface 31 with unevenness formed along the longitudinal direction across the entire upper surface of the floorboard, and a pair of recesses 32, 32 recessed in the width direction in the vertical center of the side surface of the floorboard. A plurality of lightening holes 33 that penetrate along the longitudinal direction are provided inside the floorboard 30 along the width direction. In the example shown in the figure, five lightening holes 33 are arranged side by side. This reduces the weight of the floorboard 30 while maintaining its strength.

[0024] The fascia panel 40 is a decorative panel arranged to surround the peripheral portion of the floor surface 35 formed by the floorboards 30, and has a first fascia panel 41 extending along the side of the floorboards 30 that form the floor surface 35, and a second fascia panel 42 arranged along the longitudinal end of the floorboards 30. As shown in FIG. 4, the first header board 41 is attached and fixed to the end side of the floor joist 20 via a header board fixing tool 50 . As shown in FIG. 6, the second curtain board 42 is attached and fixed to the longitudinal end of the floor board 30 via a curtain board fixing tool 50.

[0025] As shown in Figures 4 and 6, the header board 40 has a plurality of lightening holes 43 along the width direction, similar to those on the floor board 30, along the length direction. This reduces the weight of the header board 40 while maintaining its strength. Furthermore, when fastening the header board 40 to the header board fastener 50 using the fixing screws 45, the fixing screws 45 can easily penetrate, improving workability. The fixing screws 45 may be replaced with other fastening means, such as nails or rivets.

[0026] (Backboard fixing fixture 50) Next, the specific configuration of the header board fastener 50 will be described with reference to Figures 3 to 8. Figure 7 is a perspective view showing the header board fastener of the first embodiment. Figure 8 is a side view showing the header board fastener of the first embodiment. The direction of the header board fixing device 50 facing outward from the outer edge of the floor surface 35 is referred to as the outward direction, and the direction facing inward from the outer edge of the floor surface 35 is referred to as the inward direction. The direction perpendicular to the floor surface 35 is referred to as the up-down direction, and the direction perpendicular to the in-outward direction and the up-down direction is referred to as the direction in which the header board extends.

[0027] As shown in Figures 7 and 8, the fascia board fixing device 50 has a fascia board support portion 60 that supports the fascia board 40 and a deck side fixing portion 70 that is attached to a predetermined position at the longitudinal end of the joist 20 or floor board 30, and the fascia board support portion 60 and the deck side fixing portion 70 are molded integrally.

[0028] The header support portion 60 is formed in an L-shape by an attachment portion 61 extending in the vertical direction and having an abutment surface 61a that abuts against the back side of the header 40, and a support portion 62 formed on the lower end side of the attachment portion 61 and supporting the underside of the header 40. An L-shaped protrusion 63 is provided at the upper end of the mounting portion 61, protruding in the opposite direction from the support portion 62. The protrusion 63 ensures a predetermined gap between the floorboard 30, which forms the outer edge of the floor surface 35, and the header board 40.

[0029] The vertical dimension of the mounting portion 61 and the position of the support portion 62 are adjusted as appropriate depending on the dimensions of the header panel 40. Specifically, by supporting the lower end of the header panel 40 with the support portion 62, adjustments are made to eliminate any step between the upper end of the header panel 40 and the floor surface 35 formed by the floorboards 30. This improves the design of the deck structure 100 provided with the header panel 40.

[0030] The deck-side fixing portion 70 is formed to protrude in a U-shape from the upper portion of the mounting portion 61 in the opposite direction to the abutment surface 61 a, so as to fit onto the end of the joist 20 . The deck side fixing portion 70 has an upper surface portion 71 that protrudes inward from the top of the mounting portion 61, a lower surface portion 72 that protrudes inward from the middle of the mounting portion 61 in the vertical direction, a connecting portion 73 that extends in the vertical direction and connects the inner ends of the upper surface portion 71 and the lower surface portion 72, and an inclined portion 74 consisting of an inclined surface that slopes the lower part of the connecting portion 73 downward and outward.

[0031] The inner end of the upper surface portion 71 is bent in a crank shape and has a protruding edge that protrudes slightly in the vertical direction, thereby providing an upper regulating portion 75 that determines the insertion position when inserting the deck side fixing portion 70 into the hole portion 20a of the joist 20. The inner end of the lower surface portion 72 is provided with a lower regulating portion 76 that is bent in a crank shape and that determines the insertion position when the deck side fixing portion 70 is inserted into the hole portion 20a of the joist 20.

[0032] The vertical width of the deck-side fixing part 70 is formed to be shorter than the vertical width of the hole 20a of the floor joist 20. More specifically, the height position of the support part 62 relative to the placement surface when the deck-side fixing part 70 is inserted into the floor joist 20 is aligned with the height position of the support part 62 relative to the placement surface when the upper surface part 71 of the deck-side fixing part 70 is in contact with the underside of the floorboard 30. Furthermore, by supporting the lower end of the fascia board 40 on the support portion 62, the vertical dimensions of the mounting portion 61 and the fascia board 40 are adjusted so that the upper end of the fascia board 40 and the floor surface 35 are positioned on the same plane.

[0033] (Specific method for fixing the fascia board) Next, a specific method for fixing a header using the header fixing device 50 will be described with reference to Fig. 9 to Fig. 11. Fig. 9 is a diagram showing a method for fixing a first header 41. Fig. 10 is a diagram showing a method for fixing a second header. Fig. 11 is a plan view showing the arrangement of the fixing plates.

[0034] A method for fixing the first header board 41 will be described with reference to Figure 9. First, before placing the floor boards 30 that form the outer edge of the floor surface 35 on the joists 20, the header board fixing device 50 is inserted into the holes 20a of the joists 20. At this time, the header board fixing device 50 is inserted to a position where the upper and lower restricting portions 75 and 76 are caught on the joists 20. Thereafter, the header board fixing device 50 is fixed to the joists 20 by screwing the fixing screws 28 into the second step portions 23 of the joists 20.

[0035] Next, the floorboards 30 that form the outer edge of the floor surface 35 are placed and fixed on the upper surfaces of the joists 20. At this time, the floorboards 30 are fastened to the joists 20 side with flat head screws or the like.

[0036] Next, the first curtain board 41 is held in a predetermined position using the curtain board support portion 60 of the curtain board fixture 50 fixed to the floor joist 20. In this state, the first curtain board 41 is attached and fixed to the curtain board fixture 50 by screwing the fixing screw 45 from the outer surface of the first curtain board 41 toward the attachment portion 61. In this way, the first panel 41 is attached to the longitudinal end of the floor joist 20.

[0037] 10 and 11, a method for fixing the second curtain board 42 will be described. First, a fixing plate 55, which is a plate-shaped fixing aid, is inserted into the gap formed when the recesses 32 of adjacent floor boards 30 are arranged opposite each other.

[0038] Next, the header board fixing device 50 is set at a predetermined position so that the protrusions 63 abut against the longitudinal end faces of the floor board 30 and the upper surface 71 supports the floor board 30 from below.

[0039] Next, at least two fixing screws 56 are inserted into fixing holes 55a formed in the fixing plate 55 and screwed into the upper surface 71 of the header board fixing device 50. In this way, the header board fixing device 50 is attached to the floor board 30 by clamping the floor board 30 in the vertical direction using the fixing plate 55. The fixing screws 56 may be replaced with other fixing means such as nails or rivets.

[0040] Next, the second curtain board 42 is positioned and held in a predetermined position using the curtain board support portion 60 of the curtain board fixture 50 fixed to the longitudinal end portion of the floorboard 30. In this state, the second curtain board 42 is attached and fixed to the curtain board fixture 50 by screwing the fixing screw 45 from the outer surface of the second curtain board 42 toward the attachment portion 61. In this way, the second curtain board 42 is attached to the longitudinal end of the floor board 30. In addition, as shown in Figure 4, the fixing plate 55 can also be inserted into the gap formed by the recesses 32 of adjacent floorboards 30 being arranged opposite each other, and then fixed to the joists 20, etc. with fixing screws 56, thereby fixing the floorboards 30.

[0041] Furthermore, as shown in Figure 11, by curving the outer edge of the fixing plate 55 into an arc, the second curtain board 42 can be attached in the same manner even if the outer edge of the floor surface 35 formed by the longitudinal ends of the floor board 30 is not rectangular but has an inclined configuration. In the case where the outer edge of the floor surface 35 formed by the longitudinal ends of the floor plate 30 is rectangular, the fixing plate 55 may be a rectangular plate-like member.

[0042] (Assembly process of deck structure 100) Next, a method for assembling the deck structure 100 using the top panel fastener 50 will be described with reference to Fig. 12. Fig. 12 is a flow chart showing the assembly process. The method for assembling the deck structure 100 includes a base installation step, a floorboard installation step, a fixture installation step, and a fascia board attachment step.

[0043] In the foundation installation process, the support members 10 are arranged side by side on the installation surface, and joists 20 are installed so as to span the upper ends of the support members 10. In this way, a plurality of joists 20 are arranged in parallel at predetermined intervals. Adjacent floor joists 20 are connected by connecting members 25 as necessary.

[0044] In the floorboard installation process, a plurality of floorboards 30 are arranged perpendicular to the joists 20, and are arranged along the longitudinal direction of the joists 20 to form a floor surface 35. At this time, as shown in Figure 3, connecting plates are inserted into a pair of recesses 32, 32 formed on the opposing side surfaces of adjacent floorboards 30, and fixed to the joists 20 side with fixing screws or the like, thereby fixing each floorboard 30 to the joists 20 side.

[0045] In the fixture installation process, as shown in Figure 9, first, a fascia board fixture 50 is attached to the longitudinal end of the joist 20. Then, a pair of floorboards 30 are installed at the longitudinal end of the joist 20, and are fastened to the joist 20 side by screwing with countersunk screws or the like. As a result, all of the floorboards 30 that form the floor surface 35 are fixed to the joist 20 side. Next, as shown in FIG. 10, the top panel fastener 50 is attached to the longitudinal end of the floorboard 30 using the fastening plate 55.

[0046] In the panel mounting process, the first panel 41 is screwed to the panel fastener 50 attached to the floor joist 20, and the second panel 42 is screwed to the panel fastener 50 attached to the floorboard 30. In this way, the deck structure 100 is assembled, with the top panel 40 provided on the outer edge of the floor surface 35.

[0047] (Action and effect) According to the above-described deck structure 100, the header board fastener 50 for attaching the first header board 41 extending along the side of the floor board 30 that forms the floor surface 35 can be used as both the header board fastener 50 for attaching the second header board 42 provided along the longitudinal end of the floor board 30, thereby keeping costs low. Also, since it is not necessary to change the header board fastener 50 used depending on the header board 40, there is no risk of mixing up parts during assembly, improving workability.

[0048] The fascia board fixing device 50 is a single fixing device that is integrally molded with a fascia board support part 60 that supports the fascia board 40 and a deck side fixing part 70 that is attached to a predetermined position at the longitudinal end of the joist 20 or floor board 30, thereby reducing the number of parts and improving workability.

[0049] 11, the header board fixing device 50 is configured to clamp the floorboard 30 using a fixing plate 55 provided in the gap formed by a pair of opposing recesses 32, 32, and can be installed along the shape of the end of the floorboard 30. This makes it highly versatile because the second header board 42 can be attached even when the longitudinal end of the floorboard 30 is inclined with respect to the extension direction of the floorboard 30.

[0050] (Modification of the first embodiment) Next, a modified example of the header board fastener of the first embodiment will be described, focusing on the differences from the above-described example, with reference to Fig. 13. Fig. 13 is a side view showing a modified example of the header board fastener for fastening the second header board.
