Mode for Carrying Out the Invention

[0012] (First Embodiment) Hereinafter, an embodiment of a deck structure using the fascia board fastener of the present invention will be described in detail with reference to the drawings. Figure 1 is an overall perspective view showing a deck structure to which the fascia board fastener of the first embodiment is applied. Figure 2 is an exploded perspective view of the deck structure shown in Figure 1. Figure 3 is a front cross-sectional view of a part of the deck structure shown in Figure 1. Figure 4 is an enlarged view of the main part of Figure 3. Figure 5 is a side cross-sectional view of a part of the deck structure shown in Figure 1. Figure 6 is an enlarged view of the main part of Figure 5.

[0013] The deck structure 100 includes a plurality of support members 10 arranged in a row on the installation surface, joists 20 spanning between the support members 10, floorboards 30 arranged in a row on the joists 20 to form a floor surface 35, skirting boards 40 installed to surround the periphery of the floor surface, and skirting board fasteners 50 for fixing the skirting boards 40. Furthermore, the deck structure 100 may also be configured to include a frame member called a girder, which extends in a direction intersecting the joist 20, between the joist 20 and the support member 10.

[0014] The support members 10 are columnar bases arranged in a row on a mounting surface such as the ground, and are arranged in a row according to 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, as shown in Figure 2, three are arranged in a row in the direction of extension of the joists 20, and as shown in Figure 5, three are arranged in a row in the direction of extension of the floorboards 30. The lower end of the support member 10 may be embedded and fixed to the installation surface, or it may be fixed with bolts 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 joist 20.

[0015] The support member 10 is not limited to a columnar member like the one in this embodiment, as long as it is capable of supporting the joist 20. For example, the support member 10 may be provided with a height adjustment mechanism to change its height, allowing the height position at which the floor surface 35 is formed to be adjusted. As a specific example, the support member 10 may be provided with a screw groove (not shown) formed on its outer circumferential surface along the vertical direction, and an intermediate support (not shown) that engages with the screw groove. With this configuration, the height of the entire support member 10 can be continuously fine-tuned by adjusting the fastening amount of the intermediate support. The configuration for adjusting the height of the support member 10 is not limited to the above, and the height may be discontinuously adjusted by pin-fixing the support member 10 and the intermediate support. As a result, even if the installation surface on which the deck structure 100 is installed has steps, slopes, recesses due to drainage ditches, or protrusions due to beams, the floor surface 35 can be kept horizontal by appropriately adjusting the height of the support members 10.

[0016] The joists 20 are frame members installed to span the upper ends of the support members 10, and are formed in a hollow rectangular column shape, having a hole 20a along the extending direction. As shown in Figure 2, multiple joists 20 are installed parallel to each other at predetermined intervals. Adjacent joists 20 may also be connected by frame-shaped connecting members 25 that connect them to each other.

[0017] As shown in Figure 6, the joist 20 is a cylindrical frame member formed in a rectangular shape with a convex portion throughout its cross-section, and has a pair of retaining plates 21, 21 that protrude downward from both ends in the width direction of the lower surface, a pair of first-stage portions 22 that are bent in a crank shape from the middle of the vertical direction on both sides toward the top in a direction that narrows the width, and a pair of second-stage portions 23 that are bent in a crank shape above the first-stage portions 22 in a direction that further narrows the width. As a result, the entire cross-section of the joist 20 becomes convex due to the first-stage portions 22, and grooves are formed on both sides of the upper surface of the joist 20 due to the second-stage portions 23. The floorboard 30 rests on the upper surface of the joist 20, which is narrowed by a groove-shaped second stage 23.

[0018] As shown in Figures 3 to 6, the pair of retaining plates 21 are located on the outer circumferential surface of the upper end of the pair of support members 10. The joist is held in place by being sandwiched between the support members, and is fixed to the support member 10 by fixing screws 26 or the like that are inserted horizontally. This fixes the support member 10 and the joist 20 together. The fixing screws 26 may be replaced with other fastening means such as nails or rivets.

[0019] Furthermore, as shown in the example in Figure 17, the method of fixing the joist 20 and the upper end of the support member 10 is not limited to a configuration using a pair of retaining plates 21 and fixing screws 26. Figure 17 shows another embodiment of the support member and joist. The joist 20 has a flat bottom surface formed by removing the aforementioned retaining plate 21. The support member 10 is provided with a support plate 11 on 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 together by passing fixing screws 13 or the like through the lower surface of the support plate 11 on which the joist 20 is placed and through the lower surface of the joist 20. According to this configuration, even if the support member 10 becomes thinner than the joist 20 due to the use of steel or the like for the support member 10, the joist 20 can be stably fixed to the upper end of the support member 10.

[0020] Furthermore, as shown in Figure 18, a configuration may be provided in which a pair of fixing plates 15 are attached to the sides of the joists 20 that are placed on the support plate 11, on top of the support plate 11 provided at the upper end of the support column member 10. Each fixing plate 15 is formed by bending into an L-shape in plan view, and has a first portion 15a that abuts against a thin joist 20A and a second portion 15b that abuts against a thick joist 20B. Furthermore, the first portions 15a of a pair of fixing plates 15 are arranged relative to each other, and the second portions 15b are arranged relative to each other, with the distance between the second portions 15b being greater than the distance between the first portions 15a. With this configuration, the joist 20, which is placed on the support plate 11, can be fixed to the upper end of the support member 10 by fixing the side surface of the joist 20 to the pair of fixing plates 15 with fixing screws or the like. Furthermore, by appropriately adjusting the angle of the side surface of the fixing plate 15 that abuts the joist 20, joists 20 of various thicknesses can be attached and fixed, thus increasing versatility. Furthermore, each fixing plate 15 may be configured to curve in a direction that separates it from the other fixing plate 15 when viewed from above. This configuration is preferable because it allows for some leeway in the thickness of the joist 20 that can abut between the pair of fixing plates 15, thereby improving versatility.

[0021] As shown in Figures 3 and 5, connecting members 25 are fixed to a pair of first-stage sections 22, connecting the joists 20 which are arranged in parallel. Specifically, the connecting member 25 is a long, plate-like member with a U-shaped cross-section that is open at the bottom, and has flange portions at both ends in the width direction that are bent outward in the horizontal direction. With the flange portions resting on the first-stage section 22, it is fixed to the first-stage section 22 side with fixing screws 27 or the like. The fixing screws 27 may be replaced with other fixing means such as nails or rivets.

[0022] As shown in Figures 4 and 6, a fascia board fastener 50 inserted into a hole 20a in the joist 20 is fixed to the pair of second-stage sections 23 via fixing screws 28 or the like. The heads of the fixing screws 28 are positioned in the vertical gap formed between the second-stage section 23 and the upper surface of the joist 20. This allows the fascia board fastener 50, inserted into the hole 20a of the joist 20, to be easily fixed from the upper surface of the joist 20 using the fixing screw 28, while preventing the fixing screw 28 from interfering with the floorboard 30 placed on the upper surface of the joist 20. The fixing screw 28 may be replaced with other fastening means such as nails or rivets.

[0023] The floorboards 30 are longitudinal, plate-like members arranged to intersect or perpendicular to the joists 20, and when multiple floorboards are arranged in a row along the extending direction of the joists 20, they form a floor surface 35 that becomes a deck floor. As shown in Figure 5, the floorboard 30 has an uneven surface 31 with irregularities formed along the longitudinal direction across the entire upper surface of the floorboard, and a pair of recesses 32, 32 formed in the width direction at the vertical center of the side surface of the floorboard. The floorboard 30 has multiple weight-reducing sections 33 that run through it along its length and are positioned along its width. In the illustrated example, five weight-reducing sections 33 are arranged in a row. This reduces the weight of the floorboard 30 while maintaining its strength.

[0024] The skirting board 40 is a decorative board provided to surround the periphery of the floor surface 35 formed by the floorboards 30, and comprises a first skirting board 41 extending along the side surface of the floorboards 30 that form the floor surface 35, and a second skirting board 42 provided along the longitudinal end of the floorboards 30. As shown in Figure 4, the first fascia board 41 is attached and fixed to the end side of the joist 20 via a fascia board fastener 50. As shown in Figure 6, the second skirting board 42 is attached and fixed to the longitudinal end of the floorboard 30 via a skirting board fastener 50.

[0025] As shown in Figure 4 or Figure 6, the skirting board 40 has multiple weight-reducing cutouts 43 along its width direction, similar to those on the floorboard 30, along its longitudinal direction. This reduces the weight of the skirting board 40 while maintaining its strength. Furthermore, when screwing the skirting board 40 to the skirting board fastener 50 using fixing screws 45, the screws 45 penetrate more easily, improving work efficiency. The fixing screws 45 may be replaced with other fastening means such as nails or rivets.

[0026] (Fastener board fastener 50) Next, the specific configuration of the fascia board fastener 50 will be described based on Figures 3 to 8. Figure 7 is a perspective view showing the fascia board fastener of the first embodiment. Figure 8 is a side view showing the fascia board fastener of the first embodiment. The fascia board fastener 50 is defined as having an outward direction relative to the outer edge of the floor surface 35, and an inward direction relative to the outer edge of the floor surface 35. The direction perpendicular to the floor surface 35 is referred to as the up-down direction, and the direction perpendicular to the inward-outward direction and the up-down direction is referred to as the direction in which the fascia board extends.

[0027] As shown in Figures 7 and 8, the fascia board fastener 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 on the longitudinal end of the joist 20 or floorboard 30, and the fascia board support portion 60 and the deck-side fixing portion 70 are integrally molded.

[0028] The fascia board support portion 60 is formed in an L-shape by a mounting portion 61 that extends vertically and has a contact surface 61a that abuts against the back side of the fascia board 40, and a support portion 62 formed on the lower end side of the mounting portion 61 that supports the lower surface of the fascia board 40. The upper end of the mounting portion 61 is provided with a projection 63 that is L-shaped and protrudes in the opposite direction to the support portion 62. The projection 63 ensures a predetermined gap between the floorboard 30 that forms the outer edge of the floor surface 35 and the skirting board 40.

[0029] The vertical dimensions of the mounting portion 61 and the position of the support portion 62 are adjusted as appropriate according to the dimensions of the skirting board 40. Specifically, the support portion 62 supports the lower end of the skirting board 40, so that there is no step between the upper end of the skirting board 40 and the floor surface 35 formed by the floorboard 30. This improves the aesthetic appearance of the deck structure 100 on which the skirting board 40 is installed.

[0030] The deck-side fixing portion 70 is formed to protrude in a U-shape or U-shape from the upper part of the mounting portion 61 in the direction opposite to the contact surface 61a, so as to fit onto the end of the joist 20. The deck-side fixing portion 70 includes an upper surface portion 71 projecting inward from the upper part of the mounting portion 61, a lower surface portion 72 projecting inward from the middle of the mounting portion 61 in the vertical direction, a connecting portion 73 extending in the vertical direction and connecting 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 formed by inclining the lower part of the connecting portion 73 downward and outward.

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

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

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

[0034] The method for fixing the first fascia board 41 will be explained based on Figure 9. First, before placing the floorboards 30 that make up the outer edge of the floor surface 35 on the joists 20, the fascia board fixing device 50 is inserted into the holes 20a of the joists 20. At this time, the fascia board fixing device 50 is inserted until the upper restricting portion 75 and the lower restricting portion 76 catch on the joists 20. After that, the fascia board fixing device 50 is fixed to the joists 20 by screwing the fixing screws 28 into the second stage portion 23 of the joists 20.

[0035] Next, the floorboards 30 that form the outer edge of the floor surface 35 are placed on the upper surface of the joists 20 and fixed in place. At this time, the floorboards 30 are screwed to the joists 20 using countersunk screws or the like.

[0036] Next, the first fascia board 41 is held in a predetermined position using the fascia board support portion 60 of the fascia board fixing device 50, which is fixed to the joist 20. In this state, the first fascia board 41 is attached and fixed to the fascia board fixing device 50 by fastening the fixing screws 45 from the outer surface of the first fascia board 41 toward the mounting portion 61. As described above, the first fascia board 41 is attached to the longitudinal end of the joist 20.

[0037] The method for fixing the second skirting board 42 will be explained based on Figures 10 and 11. First, a fixing plate 55, which is a plate-shaped fixing aid, is inserted into the gap formed by the opposing arrangement of recesses 32 of adjacent floorboards 30.

[0038] Next, the skirting board fastener 50 is set in a predetermined position where the projection 63 abuts against the longitudinal end face of the floorboard 30 and the upper surface 71 supports the floorboard 30 from below.

[0039] Next, at least two fixing screws 56 are inserted through fixing holes 55a formed in the fixing plate 55 and screwed to the upper surface 71 of the skirting plate fixing device 50. In this way, the skirting plate fixing device 50 is attached to the floorboard 30 by clamping the floorboard 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 skirting board 42 is held in a predetermined position using the skirting board support portion 60 of the skirting board fixing device 50, which is fixed to the longitudinal end of the floorboard 30. In this state, the second skirting board 42 is attached and fixed to the skirting board fixing device 50 by fastening the fixing screws 45 from the outer surface of the second skirting board 42 toward the mounting portion 61. As described above, the second skirting board 42 is attached to the longitudinal end of the floorboard 30. Furthermore, as shown in Figure 4, the fixing plate 55 can also be used to fix the floorboards 30 by inserting it into the gap formed when the recesses 32 of adjacent floorboards 30 are positioned opposite each other, and then fixing it to the joists 20, etc., with fixing screws 56.

[0041] Furthermore, as shown in Figure 11, by curving the outer edge of the fixing plate 55 in an arc shape, the second skirting plate 42 can be attached in the same way even if the outer edge of the floor surface 35 formed by the longitudinal end of the floor plate 30 is not rectangular but has an inclined shape. If the outer edge of the floor surface 35 formed by the longitudinal end of the floorboard 30 is rectangular, the fixing plate 55 may be a rectangular plate-shaped member.

[0042] (Assembly process for deck structure 100) Next, the assembly method of the deck structure 100 using the skirting board fasteners 50 will be described based on Figure 12. Figure 12 is a flowchart showing the assembly process. The assembly method for the deck structure 100 includes a base installation step, a floorboard installation step, a fastener installation step, and a skirting board installation step.

[0043] The foundation installation process involves arranging the support members 10 in a row on the installation surface, and installing joists 20 so as to span between the upper ends of the support members 10. This allows multiple joists 20 to be arranged in parallel at predetermined intervals. If necessary, adjacent joists 20 are connected with connecting members 25.

[0044] The floorboard installation process involves arranging multiple floorboards 30 perpendicular to the joists 20 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 sides of adjacent floorboards 30 and fixed to the joists 20 with fixing screws or the like, thereby fixing each floorboard 30 to the joists 20.

[0045] In the fastening installation process, as shown in Figure 9, first, the fascia board fasteners 50 are attached to the longitudinal ends of the joists 20. Then, a pair of floorboards 30 are placed at the longitudinal ends of the joists 20 and fixed to the joists 20 using countersunk screws or the like. As a result, all the floorboards 30 that form the floor surface 35 are fixed to the joists 20. Next, as shown in Figure 10, the skirting board fastener 50 is attached to the longitudinal end of the floorboard 30 using the fixing plate 55.

[0046] The process of installing the fascia board involves screwing the first fascia board 41 to the fascia board fastener 50 attached to the joist 20, and screwing the second fascia board 42 to the fascia board fastener 50 attached to the floorboard 30. Based on the above, a deck structure 100 is assembled in which a skirting board 40 is provided on the outer edge of the floor surface 35.

[0047] (Mechanism of Action and Effects) According to the deck structure 100 described above, the fascia board fastener 50 for attaching the first fascia board 41, which extends along the side surface of the floorboard 30 forming the floor surface 35, and the fascia board fastener 50 for attaching the second fascia board 42, which is provided along the longitudinal end of the floorboard 30, can be used interchangeably, thus keeping costs low. In addition, since there is no need to change the fascia board fastener 50 used depending on the fascia board 40, there is no risk of mixing up parts during assembly work, and work efficiency is improved.

[0048] The fascia board fastener 50 is a single fastener in which a fascia board support portion 60 that supports the fascia board 40 and a deck-side fastener portion 70 that is attached to a predetermined position on the longitudinal end of the joist 20 or floorboard 30 are integrally molded, thus reducing the number of parts and improving work efficiency.

[0049] As shown in Figure 11, the skirting 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, allowing it to be installed along the shape of the end of the floorboard 30. This makes it highly versatile, as the second skirting board 42 can be attached even when the longitudinal end of the floorboard 30 is inclined with respect to the direction of extension of the floorboard 30.

[0050] (Modified version of the first embodiment) Next, based on Figure 13, a modified example of the fascia board fixing device of the first embodiment will be described in terms of how it differs from the example described above. Figure 13 is a side view showing a modified example of the fascia board fixing device for fixing the second fascia board.

[0051] The skirting board fastener 50A may be provided with a support piece 79 on its upper surface 71, which has a support surface for supporting the underside of the floorboard 30. In the example shown in Figure 13, a pair of L-shaped support pieces 79, 79 are provided at the inner and outer ends of the upper surface 71, and the lower surface of the floorboard 30 is supported by the support pieces 79. According to this configuration, the fascia board fastener 50A can also be used as a dedicated fastener for attaching the second fascia board 42 without significantly changing the overall configuration.

[0052] (Second Embodiment) Next, the skirting board fastener 50B of the second embodiment will be described based on Figures 14 and 15.
