[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-131376 Summary of the Invention [Problem to be solved by the invention]

[0004] In the structure described in Patent Document 1, special grooves are formed in the gable rafters and are used to seal gaps between adjacent roof structures, but they are useless in places where the roof structures are not adjacent, and in the end it is necessary to have both structures with and without grooves, making it less versatile.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a gap sealing structure and attachment that can make general-purpose use of end rafters. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of a gap closing structure and an attachment according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to these embodiments. First, a gap closing structure 10A and an attachment 12A according to a first embodiment of the present invention will be described.

[0011] Fig. 1 is a front view of a multi-unit carport 14 to which a gap closing structure 10A and an attachment 12A according to a first embodiment of the present invention are applied. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1.

[0012] The multi-unit carport 14 has two independent carports, 16L and 16R, located adjacent to each other on the left and right sides. The carports 16L and 16R are basically the same, and will hereinafter be referred to as the carport 16.

[0013] The carport 16 is supported at both front ends of the roof structure 18 by two pillars 20, and at the rear by a building 21. The rear of the carport 16 may be supported by pillars or the like instead of by the building 21. The building 21 may be divided into multiple buildings. The roof structure 18 slopes downward at the front so that rain drains to the front. In this embodiment, the side where people normally get on and off a vehicle parked in the carport 16 is referred to as the front, and the opposite side as the rear. However, the carport 16 does not prevent people from getting on and off through windows of the building 21, etc. For convenience, in the description of the gap closing structures 10A and 10B, the front-to-rear direction is not horizontal but is assumed to be along the sloped roof structure 18 (see Figure 4).

[0014] The roof structure 18 has multiple roofing materials 22, left and right end rafters 24L, 24R that support the edges of the roofing materials 22, a front frame 26, and a rear frame 28. The end rafters 24L, 24R are identical in shape but placed in reverse, so that they are symmetrical, and hereinafter will be referred to as end rafters 24. The attachment 12A, front frame 26, rear frame 28, and end rafters 24 are extruded materials made of metal such as aluminum (including alloys), and are configured to have a substantially uniform cross-sectional shape along their entire length. The same applies to the attachment 12B, which will be described later.

[0015] The roof material 22 is made up of long plates arranged side by side in the front-to-rear direction, and is connected to each other by rafters 30. The roof material 22 is made of, for example, polycarbonate material. The rear frame 28 also serves as a connector to the building 21. The roof material 22 is supported by the rafters 30 and the end rafters 24, which act as beams.

[0016] 3 is a cross-sectional front view of the gap closing structure 10A. The gap closing structure 10A closes the gap 32 between the roof structures 18 of adjacent carports 16L, 16R. The gap 32 is located between the end rafter 24L and the end rafter 24R. In describing the end rafters 24 and the attachments 12A, 12B, the direction in which they face each other in the gap closing structure 10A is also referred to as the X1 direction, and the direction in which they move away from each other is also referred to as the X2 direction.

[0017] The gable rafter 24 is approximately rectangular and has a side wall 24a on the X1 side facing the gap 32, and a top wall 24b that is perpendicular to the side wall 24a at its upper part. The side wall 24a is approximately vertical, and the top wall 24b is approximately horizontal. The upper half of the side wall 24a is thicker than the lower half. The top wall 24b is approximately the same thickness as the upper half of the side wall 24a. A recess 24d is formed on the X2 side of the top wall 24b, recessed so that a fastener 24c can be attached. The roof material 22 is sandwiched between a part of the recess 24d and the fastener 24c via a gasket. The fastener 24c is fixed from above to a screw fastening portion 24e formed on the X1 side of the recess 24d with a screw 33. A groove 24f is formed adjacent to the X1 side of the screw fastening portion 24e. A protrusion formed on the end of the fastener 24c fits into the groove 24f for stability. A plurality of screws 33 are provided at predetermined intervals along the front-rear direction. The heads of the screws 33 are adjacent to the top wall 24b.

[0018] The gap closing structure 10A has a pair of left and right attachments 12A and a face material 34. The left and right attachments 12A are the same shape but facing in opposite directions, and are installed symmetrically and at the same height. The height of the attachments 12A is determined by upper and lower positioning pieces 12b, which will be described later. The face material 34 is made of the same material and thickness as the roof material 22, for example.

[0019] Figure 4 is a partially enlarged cross-sectional side view of Figure 2. As shown in Figure 4, the front and rear ends of the gap closing structure 10A are covered by L-shaped members 36. One surface of the L-shaped member 36 covers the front end of the gap closing structure 10A, and the other surface is fixed to the top surface of the attachment 12A with screws 38. There are approximately two screws 38 per L-shaped member 36. There may be some distance between the rear end of the gap closing structure 10A and the building 21. Note that the L-shaped members 36 and screws 38 are omitted from Figures 3, 6, etc.

[0020] FIG. 5 is a cross-sectional front view of the left end of the gap closing structure 10A and its surrounding area. Because the gap closing structure 10A is bilaterally symmetrical, the right end will not be described. The attachment 12A has an opening 12a and upper and lower positioning pieces 12b. The opening 12a has a vertical wall 12c forming the bottom as its base, and is provided with a first protruding piece 12d and a second protruding piece 12e that protrude side by side toward the X1 side, forming a rectangular U-shape that opens toward the X1 side. In the first embodiment, the attachment 12A is oriented such that the first protruding piece 12d is on the lower side and the second protruding piece 12e is on the upper side. The vertical wall 12c is substantially vertical, and the first protruding piece 12d and the second protruding piece 12e are substantially horizontal. The attachment 12A is fixed to the end rafter 24 along its longitudinal direction (i.e., the front-to-rear direction).

[0021] A flattened C-shaped pocket 12f is formed at the tip of the first protruding piece 12d, opening slightly toward the side facing the second protruding piece 12e. A gasket 40 is attached to the pocket 12f. The gasket 40 may be attached at the time of shipment from the factory or at the construction site.

[0022] The edge of the face material 34 fits into the opening 12a, one side abutting against the gasket 40, and the backup material 42 and sealing material 44 are sealed between the other side and the second protruding piece 12e, providing watertight support. The backup material 42 overlaps the gasket 40 only over a small area in the vertical direction, but the sealing material 44 overlaps with the gasket 40 over almost its entire width. The backup material 42 and sealing material 44 are applied by workers at the construction site. The sealing material 44 is basically a liquid agent that is injected from the opening side toward the X2 side and hardens, but any material that can be sealed toward the X2 side will do.

[0023] The upper and lower positioning pieces 12b are on the extensions of the first protruding pieces 12d and protrude in the X2 direction opposite to the first protruding pieces 12d. In other words, the upper and lower positioning pieces 12b are at the same height as the first protruding pieces 12d. The thickness of the upper and lower positioning pieces 12b is slightly thicker than the vertical wall 12c, the first protruding pieces 12d, and the second protruding pieces 12e.

[0024] The protruding width of the upper and lower positioning pieces 12b is defined as W. The protruding width W is slightly larger than the horizontal width of the top wall 24b. The upper and lower positioning pieces 12b contact the top wall 24b, which forms the upper surface of the end rafter 24, and are fixed to the top wall 24b with screws (fixing devices) 46. In other words, the upper and lower positioning pieces 12b position the end rafter 24 in the vertical direction and also serve as a fixing device. Because the upper and lower positioning pieces 12b cover the top wall 24b, rainwater dripping onto the upper and lower positioning pieces 12b flows into the upper surfaces of the fasteners 24c or grooves 24f and is discharged forward along the slope, preventing it from seeping into the gap 32. A waterproof sheet may be interposed between the upper and lower positioning pieces 12b and the top wall 24b.

[0025] The screws 46 are, for example, M4 x 10 mm in size. A plurality of screws 46 are provided at predetermined intervals along the front-to-rear direction. The diameter of the head 46a of each screw 46 is defined as D. The diameter D is slightly smaller than the protruding width W. Note that the same screws 46 are basically used as a means for fixing the attachment 12A in a second embodiment (see FIG. 6) described later.

[0026] The attachment 12A has a short extension piece 12g that extends the vertical wall 12c downward in FIG. 5. The extension piece 12g and the upper and lower positioning pieces 12b form an inside corner 12h on the lower side. The corner where the side wall 24a and top wall 24b of the end rafter 24 intersect abuts against the inside corner 12h, and the inside corner 12h positions the attachment 12A laterally. The surface of the upper and lower positioning pieces 12b that forms the inside corner 12h faces downward and contacts the top wall 24b, while the opposite surface faces upward. Low bulges 12i are formed side by side on the X2 side of the vertical wall 12c. The height difference between the upper bulge 12i and the second protruding piece 12e is approximately equal to the height difference between the lower bulge 12i and the gasket 40.

[0027] The opening 12a has a width that allows the face material 34 to be inserted appropriately deep. The gasket 40 and the second protruding piece 12e are appropriately spaced apart, and the opening height H1 is wide enough to accommodate the face material 34, the backup material 42, and the sealing material 44. The opening height H1 is also sized to allow the head 46a of the screw 46 to pass through. Specifically, the opening height H1 is equal to or slightly larger than the diameter D. As described above, the upper and lower positioning pieces 12b are on the extension of the first protruding piece 12d, but they may be formed at a height near the first protruding piece 12d, and more specifically, they may be within the range of the height width H2 from the first protruding piece 12d to the gasket 40.

[0028] When constructing the gap closing structure 10A, the attachments 12A are positioned relative to the adjacent end rafters 24L, 24R. The attachments 12A are assumed to be cut to a predetermined length in advance. Positioning is performed by placing the inside corner portion 12h against the corner of the end rafter 24. In this state, the upper and lower positioning pieces 12b are in contact with the upper surface of the top wall 24b, and the two are fixed together with screws 46. The screws 46 are driven in from above.

[0029] An L-shaped member 36 is fixed to the rear ends of the two fixed attachments 12A with screws 38. Both edges of the face plate 34, cut to a specified width, are fitted into the openings 12a of the two attachments 12A and pushed rearward until they abut against the already-installed L-shaped members 36. The L-shaped members 36 are fixed to the front ends of the two attachments 12A with screws 38 to prevent the face plate 34 from coming loose. Then, a backup member 42 is inserted from the side between the face plate 34 and the second protruding piece 12e, and a sealing member 44 is poured in. This work is performed above the face plate 34. After this, a specified sealing process is performed between the building 21 (see Figure 4) and the rear end and rear frame 28 of the gap closing structure 10A.

[0030] In this way, when constructing the gap closing structure 10A, the screws 46 and 38 and the backup material 42 and sealant 44 can be driven in all at once above the facing material 34. Furthermore, when constructing the roof structural body 18, the screws 33 are driven from above to secure the roof material 22 with the fasteners 24c. Therefore, when constructing the gap closing structure 10A simultaneously with the construction of the carport 16, many tasks can be performed all at once on the facing material 34 and the roof material 22, minimizing trips to and from the ground and enabling efficient construction. Furthermore, while the facing material 34 can be inserted from the ground, it is not necessary for the worker above to descend to the ground if the worker can insert it through the opening 12a.

[0031] Next, a gap closing structure 10B according to a second embodiment of the present invention will be described. Fig. 6 is a cross-sectional front view of the gap filling structure 10B. Fig. 7 is a cross-sectional front view of the left end portion and its surrounding area of the gap filling structure 10B. The X1 and X2 directions are defined in the same way as in the gap filling structure 10A.

[0032] The gap sealing structure 10B, like the gap sealing structure 10A described above, seals the gap 32 between the roof structures 18 of adjacent carports 16L, 16R, and has a pair of left and right attachments 12A and a surface material 34, with the front and rear ends sealed by L-shaped members 36.

[0033] In the gap sealing structure 10B, the attachment 12A is provided upside down compared to the above examples. That is, the attachment 12A in the first embodiment is oriented so that the first protruding piece 12d is on the bottom and the second protruding piece 12e is on the top, whereas the attachment 12A in the second embodiment is oriented so that the first protruding piece 12d is on the top and the second protruding piece 12e is on the bottom.

[0034] In the gap closing structure 10B, the vertical wall 12c is positioned laterally against the side wall 24a of the end rafter 24 and is fixed from the X1 side toward the X2 side by a screw 46. The diameter D of the screw 46 is smaller than the opening height H1, so it can be inserted into the opening 12a. The screw 46 is driven into the side wall 24a approximately midway between the two bulges 12i.

[0035] The surface of the vertical positioning piece 12b that forms the inside corner 12h faces upward, and the opposite surface faces downward and contacts the top wall 24b, thereby determining vertical positioning. As described above, the vertical positioning piece 12b is preferably within the range of width H2. This positions the vertical positioning piece 12b outside the range of opening height H1, so it does not interfere with the male thread portion of the screw 46. Furthermore, the vertical positioning piece 12b is offset from the head 46a, allowing the head 46a to apply appropriate tightening pressure to the side wall 24a and vertical wall 12c.

[0036] When constructing the gap closing structure 10B, the attachments 12A are positioned relative to the adjacent end rafters 24L, 24R. The attachments 12A are assumed to be cut to a predetermined length in advance. Positioning is performed by placing the vertical wall 12c against the side wall 24a and the upper and lower positioning pieces 12b against the top wall 24b. In this state, the vertical wall 12c and the side wall 24a are fixed together with screws 46. The screws 46 are driven from the X1 side toward the X2 side. The setting of the face material 34 and the L-shaped member 36 is the same as in the gap closing structure 10A, but the pouring of the backup material 42 and sealing material 44 is performed below the face material 34.

[0037] In this way, when constructing the gap closing structure 10B, the screws 46 and the backup material 42 and sealing material 44 can be driven in all at once below the face material 34. Therefore, when retrofitting the gap closing structure 10B to carports 16L, 16R that have already been constructed, much of the work can be done all at once on the ground or on a stepladder, minimizing trips to the roof and enabling more efficient construction. The screws 38 that secure the L-shaped members 36 are driven in from above, but the front L-shaped member 36 can be approached from the front, and the rear L-shaped member 36 can be approached from between it and the building 21 (see Figure 4). Furthermore, the number of screws 38 is small, which reduces the burden on the worker.

[0038] In the gap closing structures 10A and 10B according to the present embodiment, the attachment 12A is separate from the end rafters 24. Therefore, the end rafters 24 themselves do not require a structure to support the face material 34, and the same end rafters 24L, 24R at the left and right ends of the left and right carports 16L, 16R can all be used, making them versatile and eliminating mistakes in attaching the shaped members. Furthermore, the gap closing structures 10A and 10B can be applied retrofit to gaps 32 created by end rafters 24 that do not have a support portion for the face material 34.

[0039] In gap closing structures 10A and 10B, the edge of face material 34 is supported by first protruding piece 12d and second protruding piece 12e within the opening of attachment 12A via gasket 40 and sealing material 44, making it applicable regardless of the width of gap 32 and eliminating the need for a dedicated mold material tailored to the width of gap 32. Because the edge of face material 34 is supported on the top and bottom, it can be prevented from lifting up. The main elements of gap closing structures 10A and 10B are the pair of attachments 12A, face material 34, and front and rear L-shaped members 36, resulting in a small number of parts.

[0040] The attachment 12A can be used upside down, and when it is preferable to install it mainly from above the surface material 34, the gap sealing structure 10A is applied with the first protruding piece 12d on the bottom and the second protruding piece 12e on the top, and when it is preferable to install it mainly from below the surface material 34, the gap sealing structure 10B is applied with the first protruding piece 12d on the top and the second protruding piece 12e on the bottom, thereby improving the freedom and efficiency of installation.

[0041] Fig. 8 is a cross-sectional front view of the left end and its surrounding area of a gap closing structure 10A to which an attachment 12B according to a modification of the attachment 12A is applied. Fig. 9 is a cross-sectional front view of the left end and its surrounding area of a gap closing structure 10B to which an attachment 12B according to a modification is applied.

[0042] The attachment 12B does not have the extension piece 12g of the attachment 12A. Furthermore, the upper and lower positioning pieces 12b of the attachment 12B are not located on an extension of the first protruding piece 12d but are located slightly closer to the second protruding piece 12e. The end of the vertical wall 12c closest to the first protruding piece 12d and the upper and lower positioning pieces 12b form a stepped recessed corner 12h. The recessed corner 12h abuts against the end of the side wall 24a in the gap closing structure 10A (see FIG. 8) to position the attachment 12B in the lateral direction. The upper and lower positioning pieces 12b are within the height width H2 and do not interfere with the fastening action of the screws 46 in the gap closing structure 10B (see FIG. 9).

[0043] The roof structure 18 is not limited to a carport, but may be a terrace, eaves, etc. A carport is also called a canopy. The present invention is not limited to the above-described embodiment, and can of course be freely modified within the scope of the present invention.

[0044] The gap sealing structure of this embodiment is a gap sealing structure between adjacent roof structures, and comprises attachments that are respectively fixed to the gable rafters of the adjacent roof structures, and a surface material that is provided between the pair of attachments, and the pair of attachments have openings formed by a first protruding piece and a second protruding piece that protrude side by side, one above the other, toward opposite sides, and both edges of the surface material are fitted into and supported by the openings in the pair of attachments.

[0045] The attachment in this embodiment is an attachment that is fixed to the end rafters of adjacent roof structures, and is characterized in that it has a vertical wall, a first protruding piece and a second protruding piece that protrude side by side from the vertical wall in one direction and form an opening together with the vertical wall, and upper and lower positioning pieces that protrude in the other direction and contact the upper surfaces of the end rafters, and the upper and lower positioning pieces are formed at the same height as the first protruding piece or at a similar height.

[0046] In this embodiment, the same end rafters can be applied to the left and right ends of adjacent roof structures, making it possible to use it in a general purpose manner.

[0047] The pair of attachments may be symmetrical and have a vertical wall that forms the bottom of the opening, and upper and lower positioning pieces that protrude from the vertical wall on the side opposite the first and second protruding pieces and contact the upper surfaces of the end rafters, the upper and lower positioning pieces being formed at the same height as the first protruding piece or at a similar height. Such attachments can be used upside down, improving flexibility in construction.

[0048] The attachment is suitable for installation from above the surface material when it is oriented so that the first protruding piece is on the bottom and the second protruding piece is on the top, and the upper and lower positioning pieces are fixed to the end rafters.

[0049] The attachment is arranged with the second protruding piece on the bottom and the first protruding piece on the top, and when the vertical wall is fixed to the end rafter, it is suitable for installation from below the face material.

[0050] The first protruding piece may have a pocket formed on the side facing the second protruding piece, and a gasket that abuts against one surface of the face material may be attached to the pocket, and the face material may be supported by abutting one surface against the gasket and sealing material enclosed between the other surface and the second protruding piece. This allows the edge of the face material to be reliably supported.

[0051] The first protruding piece may have a pocket that opens on the side facing the second protruding piece, a gasket that abuts against one surface of the face material is attached to the pocket, the attachment is oriented with the second protruding piece on the bottom and the first protruding piece on the top, the vertical wall is fixed to the end rafter with a fastener, and the gasket and the second protruding piece may be spaced apart so that the fastener can be inserted. This allows the attachment to be fixed by inserting the fastener into the opening.

[0052] The upper and lower positioning pieces may be within a height range from the first protruding piece to the gasket, so that the upper and lower positioning pieces do not interfere with fixing by a fixing tool.

[0053] The upper and lower positioning pieces and the vertical wall or the extension piece of the vertical wall may form an inside corner on the side where the first protruding piece is provided. Positioning is possible by the inside corner. [Explanation of symbols]
