Description

[Technical Field]

[0001] The present invention relates to a ceiling structure for a carport that is installed to protect parked automobiles and passengers from sunlight, wind, and rain. [Background technology]

[0002] Homes and businesses often have carports installed in their parking spaces. Carports have a variety of practical functions, such as protecting cars and passengers from sunlight, wind, and rain, and preventing snow from accumulating on cars during snowfall.

[0003] On the other hand, carports are separate structures from homes and are built in relatively visible locations, such as in front of or around homes and other buildings. Building carports in such a visible location can cause problems with the appearance, such as the carport's own supports obstructing the view or interfering with the design of the home.

[0004] Therefore, in the past, in order to create a carport with a good appearance, technologies have been developed to improve the appearance by making the ceiling material and structural materials such as beams appear separate, allowing the entire underside of the ceiling material to be seen, giving a clean impression.

[0005] For example, Patent Document 1 discloses a cantilevered carport 800, as shown in Figure 9, in which a ceiling material 81 is suspended from a roof body 82, thereby forming a flat underside 83 of the ceiling material 81. In the carport 800 of Patent Document 1, the ceiling material 81 is arranged below the roof body 82, which is a beam, and only the ceiling material 81 is visible when looking up from below, resulting in a good appearance.

[0006] Patent Document 2 discloses a technology for a carport 900 configured as shown in Fig. 10, in which struts 92 are erected on first beams 91, second beams 93 are provided on the struts 92, and a roof material 94 and a ceiling material 95 are provided to sandwich the second beams 93, thereby disposing the ceiling material 95 above the first beams 91. In the carport 900 of Patent Document 2, the ceiling material 95 is disposed below the second beams 93, so that of the two beams, the first beam 91 is hidden inside the ceiling material 95 and cannot be seen. Therefore, while having sufficient strength, only the second beams 93 and the ceiling material 95 are visible when viewed from below, resulting in a good appearance.

[0007] [Patent Document 1] Japanese Patent Publication No. 2022-160553 [Patent Document 2] Japanese Patent Application Publication No. 2020-101009 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in the carport of Patent Document 1, the ceiling material 81 is not fixed to the support pillars at the portions of the ceiling material 81 adjacent to the support pillars, and the ceiling material 81 is fixed only to the roof body 82. As a result, it is perceived that there is a gap at the boundary between the support pillars and the ceiling material 81, which is unsightly from an appearance standpoint. Furthermore, the load caused by snow accumulation and the like on the ceiling material 81 is supported only by the fixed portion with the roof body 82, which leaves concerns about its strength.

[0009] On the other hand, in the carport of Patent Document 2, second beams are attached to beams erected on first beams, and roof and ceiling materials are attached to the second beams. Therefore, even if snow accumulates on the roof, the weight of the snow is supported by the second beams, beams, and first beams, resulting in high strength. Furthermore, because the ceiling material is positioned above the first beams, the first beams are hidden by the ceiling material, making it appear as if the roof and ceiling materials are supported only by the first beams.

[0010] However, in the carport of Patent Document 2, the beams are constructed to pass through holes in the ceiling material, and the boundary between the beams and the ceiling material is sealed with a waterproof material and then closed with a decorative material. There is no detailed description of how the decorative material is fixed, but from the drawings and other information, it can be understood that it is fixed to the beam material with bolts or the like. Such a structure requires time and effort to fix the decorative member, and the bolts and the like used for fixing are visible, which results in an unsightly appearance.

[0011] The present invention was made in consideration of the above-mentioned problems, and its purpose is to provide a carport ceiling structure that can prevent a decrease in strength around the pillars and also has an excellent appearance. [Means for solving the problem]

[0012] The means adopted by the present inventors to solve the above problems will be described below. The carport ceiling structure of the present invention comprises beams that support the roof material, pillars attached to the beams, and a ceiling material that is arranged below the beams. In addition, an insert piece with a U-shaped cross section is provided at the boundary between the pillar material and the ceiling material around the pillar material, and the ceiling material is inserted and fixed into the U-shaped opening of the insert piece. Here, the beams refer to the roof support structural members that are parallel to the width direction of the carport.

[0013] Carports are equipped with various pillars, such as supports, center pillars, and beams, that are set up approximately perpendicular to the ground. Some carports also have a ceiling material installed underneath the roof material, which improves the appearance when viewed from the inside and adds value. In a carport with such a configuration, ceiling materials may be arranged around the pillars. When ceiling materials are arranged around the pillars, the boundary between the pillars and the ceiling material becomes noticeable, which can result in an unsightly appearance. In addition, the shape of the ceiling material becomes discontinuous around the beams, which can reduce the strength of the entire ceiling structure.

[0014] In the present invention, at the boundary where these vertical pillars intersect with the ceiling material, the ceiling material is inserted into the U-shaped opening of the insert piece and fixed in place, thereby giving the boundary between the pillars and the ceiling material a good appearance using the insert piece. In addition, since the ceiling material can be inserted and fixed into the U-shaped opening, the load applied to the ceiling material can be firmly supported through the insertion piece, preventing a decrease in strength around the pillar material.

[0015] In a means that can be adopted to solve the problem, the pillar material can be configured as a support, with a beam material placed above the support and a ceiling material placed below the beam material. The support pillars may be provided in pairs in the depth direction, each pair being attached to the ground. In addition, there may be multiple support pillars provided as center pillars between the pair of support pillars. The term "pillar" as used herein refers to a column material such as a pair of columns or a center column that is attached to the ground or a foundation and supports a beam or the like.

[0016] With the above-described configuration, the boundary between the pillar, which is a relatively conspicuous structure, and the ceiling material can be finished in a good appearance by the insert piece, and a decrease in strength around the pillar can be prevented.

[0017] The following configuration may be adopted as a means for solving the problem: In this configuration, the pillars are used as beams, and the structure includes a pair of posts arranged perpendicular to the ground, a first beam arranged between the pair of posts, the beams arranged on the first beams, a second beam supported by the beams and supporting a roofing material, and a ceiling material arranged below the second beams. In addition, an insertion piece with a U-shaped cross section is provided at the boundary between the periphery of the strand and the ceiling material, and the ceiling material is inserted and fixed into the U-shaped opening of the insertion piece.

[0018] In this invention, two beams, a first beam and a second beam, are provided, and the beams are supported by beams, and the roof material is placed on the second beam. This allows the weight of accumulated snow to be supported by the two beams and beams, increasing snow resistance.

[0019] In the above-mentioned structure where the roof material is supported by two beams and struts, the ceiling material is placed below the second beam. Therefore, the struts are placed as if they penetrate the ceiling material. In some cases, multiple struts are installed. In such a configuration, the boundary between the periphery of the beam and the ceiling material becomes conspicuous, which can result in an unsightly appearance. Also, the shape of the ceiling material becomes discontinuous around the beam, which can reduce the strength of the entire ceiling structure.

[0020] With the above configuration, an insert piece with a U-shaped cross section is provided, and the ceiling material is inserted into the U-shaped opening of the insert piece, so that the boundary between the post material and the ceiling material can be finished in a good appearance by the insert piece. In addition, since the ceiling material can be inserted into the U-shaped opening and fixed in place, the load applied to the ceiling material can be firmly supported through the insertion piece, preventing a decrease in strength around the beam material.

[0021] The following means can be used to solve the problem. In the present invention, it is also possible to provide a plurality of purlins and / or a plurality of auxiliary beams below the second beam, and to attach the insertion pieces to the plurality of purlins or the plurality of auxiliary beams.

[0022] The width of the beam may be approximately the same as the width of the first beam and the second beam. When attaching the insert to the second beam, some of the inserts arranged around the beam may have a space above them where there is no second beam. In this case, there may be concerns about the attachment strength of the insert. In contrast, in the above configuration, multiple purlins or multiple auxiliary beams are provided below the second beam, and by attaching the insert to any of these, all of the inserts can be firmly attached, ensuring sufficient attachment strength.

[0023] As other means that can be adopted to solve the problem, the following means can also be used. In the present invention, the post has a rectangular cross section, and the inserts are provided around the post with the openings facing outward. When the inserts are attached, both longitudinal ends of the surface facing the first beam (the exterior surface) can be angled at 45 degrees. When the post has a rectangular cross section and four inserts are arranged around it, the four inserts can be combined and arranged around post 3 so that both 45-degree ends of the exterior surface face each other. Arranging them in this way allows for outward-facing openings to be formed without gaps around the entire post.

[0024] Another method that can be adopted to solve the problem is to use siding material that extends in the girder direction as the ceiling material, cut out a portion of the opposing side end of adjacent ceiling materials in the width direction, and insert the cut-out portion into the opening of the insertion piece to secure it in place. The girder direction refers to the direction perpendicular to the beam material and parallel to the depth direction of the carport.

[0025] In the above configuration, by inserting the notched ceiling material into the insertion piece, the insertion piece serves both as a fixing piece and a dividing piece, and the ceiling material can be attached neatly around the post. In addition, by cutting out a portion of the opposing side edges of adjacent ceilings, the ceiling material can be inserted from both sides so that it is sandwiched between the two ceiling materials, making it easy to install the ceiling material. [Effects of the Invention]

[0026] The ceiling structure of the carport of the present invention is configured so that insert pieces with a U-shaped cross section are provided around the pillar material, and the ceiling material is inserted into the U-shaped opening of the insert piece, thereby preventing a decrease in strength around the pillar material and allowing the boundary between the beam and the ceiling material to be neatly processed.

[0027] In this way, the carport ceiling structure of the present invention can fix the ceiling material using an insert piece at the boundary between the pillar material and the ceiling material, which not only prevents a decrease in strength around the pillar material but also has the effect of producing a carport ceiling structure that has excellent appearance.

[0029] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In the following description, the drawings are shown in a schematic manner to simplify the description, and for example, the number of bundles and bolts is shown in the drawings less than in the actual embodiment.

[0030] [Basic structure of a carport] First, the basic structure will be described. A carport 100 employing the carport ceiling structure of the present invention is a residential carport capable of parking automobiles, as shown in Fig. 1. The carport 100 in Fig. 1 is a carport for two cars, and has three rows of support posts 1·1, which are pairs of pillars arranged perpendicular to the ground, in the front-to-rear direction. The support pillar 1 is a hollow metal member having a predetermined cross-sectional shape, and is installed on a foundation made of poured concrete. The number and arrangement of the support pillars 1 are adjusted appropriately depending on the required snow resistance and number of parking vehicles.

[0031] As shown in the cross-sectional view of Figure 1, the carport 100 comprises first beams 21 arranged between a pair of supports 1, a plurality of struts 3 arranged on the first beams 21, and second beams 22 supported by the struts 3 and supporting a roof material 4. The roof material 4 is a so-called folded-plate roof that slopes slightly downward from the rear to the front, allowing rainwater to flow in one direction. In addition, second girders 52, 52... are also provided at predetermined intervals on the upper part of the second beams 22, 22..., and the convex part of the folded plate roof is supported by these second girders 52, 52...

[0032] Additionally, a plurality of first beams 51 are provided at predetermined intervals below the second beams 22 that support the roof material 4. Auxiliary beams 23 are provided below the first beams 51, and ceiling materials 6 are attached to the auxiliary beams 23. In other words, when looking up at carport 100 from below, the first beams 21-21... and the beams 3-3... can be seen, while the second beams 22-22... are hidden by the ceiling materials 6-6... and cannot be seen, so that although two beams 2 support the roof material 4, at first glance it appears as if only the first beams 21-21... are supporting the ceiling materials 6-6...

[0033] The first beams 21, 21..., second beams 22, 22..., beams 3, 3..., and girders 5, 5... can be hollow metal members like the support columns 1, but may also be made of fiber-reinforced resin or the like. In addition, although a siding material is used as the ceiling material 6 in the embodiment of FIG. 1, a resin plate on which a pattern is applied by printing or press processing may also be used.

[0034] In the above configuration, two beams 21 and 22 are used for the beams, with a plurality of struts 3, 3... serving as pillars between them, but it does not necessarily have to be composed of two beams and struts; it may also be composed of a beam that supports the roof material, pillars such as supports attached to the beams, and a ceiling material placed below the beams.

[0035] [Sloped ceiling structure] Next, we will explain in detail the ceiling structure of the carport 100. The ceiling structure of the carport 100 has different configurations for the ceiling directly above the space where cars are parked and the front entrance area where cars enter. Focusing on the front portion (the side where cars enter and exit), the first ceiling materials 61, 61... directly above the parking space are arranged approximately parallel to the roof material 4, whereas in the front portion, the second ceiling materials 62, 62... are configured to slope upward toward the front.

[0036] To explain the structure of this front portion in more detail, as shown in Figure 2, the structure of the front portion comprises a second beam 22 supporting the roof 4, a first girder 51 arranged below the second beam 22, a second girder 52 arranged above the second beam 22, and a tilt beam 23 attached below the second girder 52 and forward of the second beam 22.

[0037] Furthermore, a trim 7 is provided between the first ceiling material 61 and the second ceiling material 62 via another member. This trim 7 has a first surface 71 that is approximately parallel to the first ceiling material 61 and a second surface 72 that is approximately parallel to the second ceiling material 62. Note that the trim 7 may be provided directly between the first ceiling material 61 and the second ceiling material 62 without using another member.

[0038] The first beam members 51, 51... are arranged approximately parallel to the roof material 4 from directly above the parking space to the rear, and the first ceiling members 61, 61... are arranged below them, forming a ceiling approximately parallel to the roof material 4.

[0039] Regarding the fixing structure of the trim 7, in the embodiment shown in Fig. 2, the trim 7 is attached to the second beam 22 by engaging with the fixing member 8 via multiple parts. The fixing member 8 may be an integrated part, but in the embodiment shown in Fig. 2, it is divided into a first fixing member 81 and a second fixing member 82. In other words, the trim 7 is attached by engaging with the first fixing member 81 and the second fixing member 82.

[0040] Here, the cross-sectional shape of the first fixing member 81 is a substantially U-shape that opens to the rear side, and the cross-sectional shape of the second fixing member 82 is a substantially U-shape that opens to the front side. The trim material 7 is configured so that a portion thereof extends from the first surface 71 and can engage with the opening side of the first fixing member 81, and another portion thereof extends from the second surface 72 and can engage with the opening side of the second fixing member 82.

[0041] 2, the trim 7 and the first and second ceiling materials 61 and 62 are inserted into the openings of the first fixing member 81 and the openings of the second fixing member 82. This ensures that the first and second ceiling materials 61 and 62 are securely fixed, and does not impair the ease of installation of the trim 7.

[0042] Meanwhile, lighting fixtures L, such as downlights, are provided at predetermined intervals on the sloped ceiling. These lighting fixtures L are attached so as to project light perpendicular to the sloped second ceiling materials 62. This allows for a wide area in front of the carport 100 to be illuminated when parking a car at night. This makes parking at night easier than when light is projected perpendicularly to the ground, and also helps prevent accidents. The lighting L may be provided in the ceiling portion parallel to the roof material 4, and by irradiating light in a direction perpendicular to the first ceiling material 61, the entire interior of the carport 100 can be brightened. This makes it easier to get in and out of the car at night.

[0043] As described above, by providing the trim 7 between the first ceiling material 61 parallel to the roof material 4 and the second ceiling material 62 inclined relative to the first ceiling material 61, the gap between the first ceiling material 61 and the second ceiling material 62 can be neatly concealed. Furthermore, by making the appearance of the trim 7 the same as that of the first ceiling material 61 and the second ceiling material 62, when the carport 100 is viewed from the front, the first ceiling material 61 and the second ceiling material 62 appear to form a single ceiling, and the thickness of the roof material 4 and the second ceiling material 62 appear thin, resulting in a neat appearance.

[0044] [Roof support structure] Next, the roof support structure of the carport 100 will be described in detail. As described above, the roof support structure of the carport 100 includes a pair of posts 1-1 arranged perpendicular to the ground, first beams 21-21 arranged between the pair of posts 1-1, a plurality of struts 3-3 arranged on the first beams 21-21, and second beams 22-22 supported by the struts 3-3 and supporting the roof material 4. In addition, a plurality of first beams 51-51 are arranged at predetermined intervals below the second beams 22-22 supporting the roof material 4. Furthermore, first ceiling materials 61-61 are arranged below the first beams 51-51.

[0045] Figure 3 shows a cross section at the position of beam 2. The first beam 21 and post 3 are fixed together via metal fittings A·A... with a U-shaped cross section that are fixed inside post 3. Similarly, the second beam 22 and post 3 are fixed together via metal fittings A·A... with a U-shaped cross section that are fixed inside post 3. Metal fitting A has fastening holes A1·A1... on each of its three sides, and the fastening holes A1·A1... on the two opposing sides have been burred and are female-threaded, while the fastening hole A1·A1... on the remaining side is a normal hole without a female thread.

[0046] The beam 3 is fixed to the second beam 22 by fastening a through hole 221 provided in the second beam 22 to a fastening hole A1 provided in the metal fitting A with a nut and a bolt inserted inside the second beam 22. 3, second beam 22 is provided with rails 222 extending in the longitudinal direction, and connecting bolts B, which are bolts fixed to plate materials, can be inserted along the rails. These rails have a retaining structure, so that connecting bolts B can be inserted from the end and slid longitudinally, preventing them from falling out of second beam 22 and allowing them to be positioned in the desired position.

[0047] On the other hand, the post 3 and the first beam 22 are fixed together by fastening the through hole 211 formed in the first beam 21 to the fastening hole A1 formed in the metal fitting A using a bolt that can be fastened without using a nut. An example of a bolt that can be fastened without using a nut is a roof bolt R. The first beam 21 also has a rail portion 212 extending in the longitudinal direction, but as shown in Figure 3, the rail portion 212 is arranged facing downward, and the upper surface side to which the beam 3 is fixed does not have a rail portion 212.

[0048] By using the roof bolts R, even on the upper surface side of the first beam 21 where there is no rail portion 212, there is no need to insert nuts inside and fasten with bolts. Generally, when tightening a bolt to a nut, it is necessary to hold the nut down with hands, a wrench, etc. to prevent the nut from falling inside the first beam 21. However, when the beams 3·3... are installed in an out-of-reach location more than 1 m away from both ends of the first beam 21, it is not possible to hold the nut down with hands, a wrench, etc. Therefore, by using the roof bolt R, even if the location is difficult to reach, the metal fitting A and the second beam material 22 can be fastened together simply by tightening the roof bolt R from the outside with a wrench without using a regular nut.

[0049] To fix the stack 3 to the metal fitting A, bolts (not shown) are inserted into bolt holes 31, 31... provided on two opposing sides of the stack 3, and fixed to the female-threaded fastening hole A1 of the metal fitting A.

[0050] Here, it seems that if a hollow member with a rail portion 221 like the second beam 22 is used for the first beam 21 on the upper surface, it would be possible to position the connecting bolt B that secures the bolt to the plate material without it falling off. Indeed, hollow parts with rail portions are commonly used in the field of carports.

[0051] However, hollow parts generally used in carports have rails on only one side, not on both sides. Here, the first beam 21 is fastened to the posts 1 using connecting bolts B (not shown). Therefore, the first beam 21 must be arranged so that the rail portion 221 faces downward, and the upper surface side has no rail portion 212. In this case, the connecting bolt B cannot be used for the beam 3 fixed to the upper surface portion.

[0052] Therefore, the first beam 21 is fixed to the post 3 using a roof bolt R that can be fastened without using a nut. On the other hand, a hollow member provided with a rail portion 222 is used for the second beam material 22 supporting the roof material 4, and the post material 3 and the second beam material 22 are fixed together using connecting bolts B and ordinary nuts.

[0053] By using this configuration, even if the carport has a long span beam 2, the beams 3·3... can be installed at a position more than 1 m away from both ends of the first beam 21, making the carport strong overall. Furthermore, although it is a high-strength structure using the first beam 21 and the second beam 22, the second beam 22 is configured so as not to be visible due to the ceiling material 6, so there are fewer unrefined beams 2 visible, and the appearance is also excellent.

[0054] [Roof support structure assembly procedure] The above-described roof support structure is assembled according to the procedure shown in FIG. First, as shown in Figure 4(a), metal fitting A is attached with bolts and nuts to a predetermined position on the second beam 22. As described above, a connecting bolt B is inserted from the end into the rail portion 222 provided on the second beam 22, and metal fitting A is fixed at a position where the fastening hole A1 of metal fitting A corresponds to the through-hole 221 of the second beam.

[0055] Next, as shown in Figure 4(b), the metal fitting A is attached to the first beam 21 at a predetermined position, similar to the second beam 22. At this time, instead of using a typical bolt and nut, a roof bolt R is inserted from the fastening hole A1 of the metal fitting A through the through hole 221 of the first beam 21. Then, by turning the nut screwed onto the shaft of the roof bolt R with a roof screwdriver or the like, the metal fittings at the tip of the roof bolt R open, forming a retaining member on the inside of the first beam material 21 and fixing it in place.

[0056] Then, as shown in FIG. 4(c), the beam 3 is sandwiched and installed between the first beam 21 and the second beam 22 to which the metal fittings A are attached. Specifically, first, the first beam 21 is attached to the support posts 1·1, and therefore the bracket 3 is first attached to the first beam 21. At this time, the bracket A of the first beam 21 is inserted into the hollow portion of the bracket 3.

[0057] Next, the threaded fastening holes A1·A1... on the two opposing surfaces of the metal fitting A are aligned with the bolt holes 31·31... on the corresponding positions of the bundle 3, and bolts are inserted into the bolt holes 31·31... to secure the metal fittings in place.

[0058] Finally, the second beam 22 with the metal fittings A attached is placed on the post 3, and similarly, the threaded fastening holes A1·A1... on the two opposing surfaces of the metal fittings A are aligned with the bolt holes 31·31... on the corresponding positions of the post 3, and bolts are inserted into the bolt holes 31·31... to secure it in place.

[0059] By following the above procedure, even when it is necessary to attach the beams 3 at positions 1 m or more away from both ends of the first beam 21, a high-strength roof support structure can be easily assembled.

[0060] [Ceiling structure around beams] Next, the ceiling structure around the struts 3, which are the pillars in the carport 100, will be described in detail. Figure 5 is a diagram showing the state around the struts 3 when looking up at the ceiling of the carport 100 from below. As mentioned above, the roof support structure of the carport 100 includes a pair of posts 1·1 arranged perpendicular to the ground, first beams 21·21... arranged between the pair of posts 1·1, a plurality of struts 3·3... arranged on the first beams 21·21..., and second beams 22·22... supported by the plurality of struts 3·3... and supporting the roof material 4.

[0061] 5, an insertion piece 9 having a U-shaped cross section is attached to the periphery of the post 3 on the side of the second beam 22. The ceiling material 6 can be inserted and fixed into the opening 91 of this insertion piece 9. Here, a plurality of purlins 53 are provided below the second beam 22, and a plurality of auxiliary beams 24 are provided below the plurality of purlins 53. The insertion pieces 9 are attached to the plurality of auxiliary beams 24.

[0062] As shown in Figure 6, the insertion pieces 9 are formed by bending a thin metal or resin plate into a U-shape. The exterior surface 92, which is the surface that faces the first beam 21 when installed, has both ends at a 45-degree angle, and four insertion pieces 9 are combined and arranged around the stringer 3 so that both 45-degree ends face each other. By arranging them in this way, it is possible to form openings facing outward without gaps all around the entire periphery of the stringer 3.

[0063] Furthermore, the exterior surface 92 is surface-treated to have the same appearance as the ceiling material 6. For example, if the ceiling material 6 is a wood-grain siding material, the exterior surface 92 of the insert piece 9 is also surface-treated by printing or the like to have a wood-grain appearance.

[0064] On the other hand, the surface of the insertion piece 9 opposite the exterior surface 92 is an attachment surface 93 for the auxiliary beams 24. The attachment surface 93 has a larger area than the exterior surface 92, and can be fixed to the auxiliary beams 24 by drilling holes and using screws (not shown) or the like. At this time, the attachment surface 93 is shaped so as not to interfere with the attachment surfaces 93 of adjacent insertion pieces 9.

[0065] Four of the above-mentioned insert pieces 9·9... are combined and arranged around the post 3, and the ceiling material 6 is inserted into the openings facing outward. At this time, a portion of the opposing side end of each of the adjacent ceiling materials 6·6 is cut out, and the cut-out portion is inserted into the opening of the insert piece 9 and fixed.

[0066] In the above configuration, the configuration around the post 3 as a pillar material has been described, but the insertion piece 9 can also be configured in the same way not only around the post 3 but also around the support 1 as a pillar material. When insert pieces 9 are used around the support posts 1 as pillar materials, they are particularly suitable for application to the center posts (not shown). The center posts are installed as additional posts between a pair of left and right support posts 1, 1 when improving snow resistance in carports with a large parking capacity.

[0067] At the boundary between the center pillar and the ceiling material 6, four insertion pieces 9 are combined and arranged around the center pillar so that both 45-degree ends of the exterior surface 92, which is the surface that faces the first beam 21 during installation, face each other. By arranging them in this way, it is possible to form openings facing outward without gaps all around the center pillar. However, this can be applied not only to the center pillar but also to the peripheral areas of the left and right pillars 1·1.

[0068] In this way, by attaching the insert pieces 9·9... around the pillar materials such as the beam 3 and the supports 1·1 and inserting the notched ceiling materials 6·6... into the insert pieces 9·9..., the insert pieces 9·9... serve as both fixings and screens, allowing the ceiling material 6 to be attached neatly around the beam 3. In addition, by cutting out a portion of the opposing side end portions of adjacent ceiling materials 6 / 6, the beam 3 can be inserted from both sides so that it is sandwiched between the two ceiling materials 6 / 6, making it easy to install the ceiling material 6.

[0069] "Variation 1" The present invention is not limited to the above-described embodiment, and other embodiments can also be adopted. In the embodiment shown in Figure 2, the second ceiling materials 62, 62... sloping upward toward the front are directly fixed to the tilt beams 23. In contrast, the ceiling structure of the carport 101 shown in Figure 7 is different in that the tilt girders 54 are fixed to the tilt beams 23, and the second ceiling materials 62 are fixed to the tilt beams 54.

[0070] In this modification, the second ceiling material 62 is fixed to a sturdy tilting beam 54, which is fixed to the second beam 52 via a splint. As a result, even if a load such as snow acts on the roof material 4, the load can be supported by the tilting beam 54, preventing the tilted second ceiling material 62 from tilting or warping.

[0071] "Variation 2" In addition to the above, the present invention can also adopt other forms. The carport 102 shown in Figure 8 differs in that the end of the second ceiling material 62 is in contact with the side of the second beam 22, and is inclined forward from the side of the second beam 22 by a fixing member 8 provided in the middle of the second beam 22.

[0072] To improve snow resistance, the height of the second beams 22 must be increased. However, if the height of the second beams 22 is increased, the angle of inclination of the second ceiling material 62 increases, making the roof appear thicker.

[0073] In this modified example, even if the second beam 22 is tall, by fixing the end of the second ceiling material 62 so that it abuts the side of the second beam 22, the visible area of ​​the sloping second ceiling material 62 can be reduced when the carport 102 is viewed from the front, and the carport can be given the appearance of a thin, neat roof while still being highly strong.

[0074] As described above, the present invention allows for the inexpensive construction of a carport ceiling structure that is highly snow-resistant and has a good appearance, but the present invention is not limited to the above-described embodiment and various modifications are possible. For example, the trim 7 may be attached directly to the beam 5 rather than to the fixing member 8. [Explanation of symbols]
