Description

[Technical Field]

[0001] The present invention relates to a tile roof and a construction method thereof, and more particularly to a tile roof that easily achieves waterproof specifications, a construction method thereof, and a waterproof construction method. [Background technology]

[0002] A well-known method of roofing used in residential buildings, factories, and other structures is shingling, in which metal sheets such as galvanized iron or Galvalume steel sheets (registered trademark) are laid along the slope of a gently sloping roof, with square rod-shaped core materials called shingle bars filling the gaps between the sheets. As shown in Figure 1, multiple shingle bars are installed in parallel from the ridge of the roof to the eaves. More specifically, sheathing boards are laid across the entire roof on top of the roof rafters and secured in place, and a waterproof sheet is then laid over the entire roof using asphalt roofing or similar. Metal sheets called groove boards are then passed over this waterproof sheet, leaving gaps large enough for retaining bars, and the sheets are then laid one after the other.

[0003] As shown in Figure 6, the groove plate has both side edges bent upward to form raised sections. A through-clip is inserted into the gap in this groove plate. The through-clip is nailed to the base material. In conventional seam-fastened tile bar roofing, as shown in Figure 6, a tile bar cap is placed over the through-clip, and the downward bent section of the tile bar cap is bent inward to crimp the horizontal sections of the groove plate, the through-clip, and the tile bar cap together, and the crimped section is then folded downward around its base end to join them. In fitting-type tile bar roofing, the seam section of the tile bar cap engages with the raised section of the groove plate and the seam section of the through-clip.

[0004] With traditional tile roofing, whether it's a seam or a joint, rust develops at the metal joints over time, and the joints are prone to loosening due to thermal deformation of the metal. If the tile joints are not tightly fastened properly, rainwater can easily seep into the gaps. If rainwater seeps into the inside of the grooved boards, the waterproof sheet laid on the underlayment alone will not be able to maintain waterproofing. This results in leaks and condensation on the ceiling, and mold can develop due to the moisture from the rainwater.

[0005] Patent Document 1, for example, discloses a tile roofing material for improving waterproofing at the joints of tile bars in a tile roof. The material comprises a metal plate member, formed by bending two opposing sides of a rectangular metal plate in the same direction to form a bent portion, with a waterproof sheet, which may have adhesive means on one or both sides, affixed to the outer surface of the bent portion of the metal plate; and a cap, formed by affixing a waterproof sheet, which has an adhesive layer on both sides, to the inner surface of the metal plate with a generally U-shaped cross section. When the metal plate members are arranged in parallel and a retaining clip is placed between them, the inner side of the cap is placed over the bent portions of both the metal plate member and the adjacent metal plate member, and the waterproof sheet is sandwiched between both ends of the cap while the cap is bent. However, this invention requires a significant amount of work at the construction site to attach the waterproof sheet to the tile bars. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2002-61340 Summary of the Invention [Problem to be solved by the invention]

[0007] In order to ensure waterproofing of a tile roof, it is desirable to apply a waterproof coating to the entire tile roof. Conventional tile roofs have a complex structure, particularly in the fastening area of ​​the tile cap, which makes waterproofing difficult because the waterproofing performance and design are easily affected by the skill of the sprayer.

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a tile roof that can easily achieve waterproofing, a construction method therefor, and a waterproofing construction method. [Means for solving the problem]

[0009] After extensive research, the inventors have found that the above-mentioned problems can be solved by limiting the tile bar cap to a specific structure and material. That is, the present invention provides a tile bar roof including a roof board section comprising a plurality of grooved boards, each having raised portions formed by bending upward both ends of a bottom board section, and a tile bar section equipped with tile bar caps that integrally cover adjacent raised portions when the grooved boards are laid at a predetermined interval, wherein the tile bar caps have a structure in which their lower open ends fit sideways into the raised portions of the grooved boards, and are made of polyurethane resin.

[0010] It is preferable that the downwardly open end of the tile bar cap further comprises a horizontal portion, and that the horizontal portion is in close contact with the bottom plate portion of the groove plate.

[0011] The present invention also provides a roof panel section having a plurality of grooved panels laid thereon, each having a raised section formed by bending both side edges of the bottom panel section upward; A shingle bar portion provided with a shingle bar cap that integrally covers the adjacent raised portions with the groove plates laid at a predetermined interval. A method for constructing a tile roof comprising the steps of: A step of previously preparing the tile rod cap from a polyurea resin; and A step of fitting the tile cap onto the raised portion of the groove board at the site where the tile roof is being constructed. The present invention provides a method for constructing a tiled roof, comprising:

[0012] The present invention further provides a roof panel section having a plurality of grooved panels each having a raised portion formed by bending both side edges of the bottom panel section upward; A shingle bar portion provided with a shingle bar cap that integrally covers the adjacent raised portions with the groove plates laid at a predetermined interval. a waterproofing method for a tile roof comprising: a tile cap having a structure in which an end portion of the tile cap that is open downward fits into a side of the rising portion of the groove plate, and the tile cap is made of a polyurethane resin, the waterproofing method comprising the following steps: A step of previously preparing the tile rod cap from a polyurea resin; A step of fitting the tile cap to the rising portion of the groove board at a construction site of a tile roof; A step of painting the tiled roof together with the tile caps with a waterproof paint. The present invention provides a waterproofing method for the tile roof, which comprises:

[0013] The waterproof coating is preferably a polyurethane resin or a urethane resin.

[0014] The present invention also provides a tile bar cap for a tile bar roof, which includes a roof board section laid with a plurality of grooved boards, each having raised sections formed by bending upwards both side ends of a bottom board section, and a tile bar section equipped with a tile bar cap that covers adjacent raised sections together when the grooved boards are laid at a predetermined interval, wherein the tile bar cap has a structure in which the open lower end fits into the side of the raised sections of the grooved boards and is made of polyurethane resin. [Effects of the Invention]

[0015] The tile roof and tile cap used therein of the present invention have a simple structure in which the open end at the bottom fits into the raised portion of the groove plate. Therefore, when a craftsman sprays polyurethane resin onto that portion, it is not dependent on the craftsman's skill or consideration for waterproofing or design, and waterproof specifications are achieved extremely easily. The tile cap structure of the present invention does not have a seam like conventional tile caps, so it can also prevent rainwater from entering through gaps in the seam due to capillary action. Even if gaps do occur, the water-repellent properties of the polyurethane resin of the tile cap reliably prevent rainwater from entering.

[0016] In the tile roof construction method of the present invention, the polyurea tile caps are prepared outside the construction site, for example, indoors, so problems such as inability to carry out on-site construction due to bad weather can be avoided. Furthermore, there is no need to forcibly bend flat metal sheets during construction, making the tile installation process itself extremely simple. There is also no risk of poor appearance, such as loosening after construction. Thus, the construction method of the present invention greatly improves the partial work required for roof waterproofing work, which has traditionally been difficult to carry out due to its dependence on weather.

[0017] The waterproofing method for tiled roofs of the present invention significantly improves the waterproofing of the entire roof, including the tile bar sections. In other words, since the entire roof, including the tile bar caps, does not have a complex structure that is difficult to paint, the on-site spraying work is simpler than before and there is no variation in the paint application by craftsmen. Furthermore, the present invention eliminates the labor required for prior roof priming work, which was previously necessary, and can shorten the construction period.

[Figure 5] 1 is a diagram showing the components of the tile bar portion of a tiled roof of the present invention and the assembly sequence thereof. [Figure 6] 1 is a diagram showing the parts of the tile bar portion of a conventional tile-roofed roof and the assembly sequence thereof. DETAILED DESCRIPTION OF THE INVENTION

[0019] The following describes embodiments of the present invention using the accompanying drawings, but the present invention is not limited to the following embodiments. Tiler roofing methods are generally broadly divided into core-wood tile roofing methods, in which square timbers called cores that connect and reinforce the tile bar sections are inserted and fixed with nails, and then wrapped with tile bar caps, and coreless tile roofing methods, in which through retaining clips are installed instead of cores. The present invention is applicable to both core-wood and coreless tile roofing methods, but will be described based on coreless tile roofing methods.

[0020] As shown in Figure 1, the entire tiled roof of the present invention consists of a roof board section 10 formed of groove boards 50 and tile bar sections 20 installed at predetermined intervals between each groove board, just like the conventional tiled roof. The parts required for the tiled roof of the present invention and the assembly sequence are shown in Figure 5.

[0021] In Figure 5, the groove plate 50 laid to form the roof plate portion 10 is made of metal, such as galvanized steel plate (registered trademark), hot-dip galvanized steel plate, painted hot-dip galvanized steel plate, stainless steel plate, vinyl chloride resin metal laminate plate, aluminum, aluminum alloy plate, titanium-zinc alloy plate, copper plate, etc., and galvanized steel plate (registered trademark), which is made of aluminum and zinc and has a plated surface, is commonly used.

[0022] The groove plate 50 has a rectangular bottom plate portion 51. Two opposing pieces of the groove plate 50 are bent upward at approximately right angles from the bottom plate portion 51 to form raised portions 52 of the groove plate. The upper ends of the raised portions 52 are further bent toward the other end to form horizontal portions 53 of the groove plate.

[0023] When the groove plates 50 are arranged at a predetermined interval 54, the raised portions 52 of adjacent groove plates 50 form the sides of the shingle bar portion 20 described below, and the horizontal portions 53 of the groove plates bent from the raised portions 52 become the support portions for the horizontal portions of the through-clip 60 described below.

[0024] A through retaining clip 60 is disposed between the rising portions 52 of adjacent groove plates. The through retaining clip is made of metal and has a substantially U-shaped cross section with an open upper portion.

[0025] The upper portions of both sides of the through retaining clip 60 are further bent horizontally outward to form horizontal sections 61. The horizontal sections 61 of the through retaining clip and the horizontal section 53 of the groove plate are overlapped. These overlapping horizontal sections are then bent downward together to form the folded section 55 of the groove plate and the folded section 63 of the through retaining clip, respectively. This integrates the groove plate 50 and the through retaining clip 60, making the shingle rod section strong.

[0026] By screwing fastening nails 64 such as nails or screws into the base material 11 (sheathing boards or rafters) into the bottom plate portion 62 of the through retaining clip, the groove plate 50 is firmly fixed to the base material 11 via the through retaining clip 60.

[0027] The groove plates 50 are laid at a predetermined interval 54, and a shingle bar cap 70 is fitted onto a pair of adjacent raised portions 52 with a through-hole retaining clip 60 superimposed thereon.

[0028] Unlike conventional metals, the material for the tile bar cap 70 used in the present invention must be polyurea resin. Polyurea resin has the mechanical strength to maintain the shape of the tile bar cap, absorbs temperature changes between days and seasons, is weather-resistant, and does not corrode. It also blends well with polyurethane-based and polyurethane-based waterproof paints and adheres well to polyurethane-based adhesives.

[0029] Polyurea resin is difficult to mold on-site. Prior to on-site construction of the tile rod cap, the polyurea resin is molded into the shape of the tile rod cap in a separate location (e.g., indoors) by applying the polyurea resin to a core material, drying it, and then separating the core material, or by injecting the polyurea resin into a mold and drying it.

[0030] The tile bar cap 70 is shaped so that the open lower end 72 of the side surface 71 fits into the raised portion 52 of the groove plate. In other words, the width of the tile bar cap 70 is approximately equal to the width of the gap 54 formed between the raised portions. By sandwiching the raised portion 52 of the groove plate, the tile bar cap 70 blocks the intrusion path of rainwater and prevents it from entering the tile bar portion. Furthermore, the water-repellent property of the polyurethane resin effectively prevents the capillary action of rainwater.

[0031] The top surface 74 of the shingle rod cap has a shape such as flat, arcuate, concave, convex, triangular, or pentagonal in cross section.

[0032] There are no particular restrictions on the length of the side surface 71 of the shingle bar cap 70, as long as the lower end 72 of the shingle bar cap fits into the side of the raised portion of the groove plate. In the first form shown in Figure 2, the lower end 72 of the shingle bar cap is located at the middle of the raised portion 52 of the groove plate.

[0033] In the second configuration shown in Figure 3, the lower end 72 of the shingle bar cap extends all the way to the bottom plate portion 51 of the channel plate. This configuration widens the engagement area between the shingle bar cap 70 and the raised portion 52 of the channel plate, making it difficult for the shingle bar cap to come off and preventing rainwater from entering. Furthermore, the robustness of the shingle bar cap 70, which is made of polyurethane resin, firmly supports the raised portion of the channel plate 50 and the through retaining clip 60. The shingle bar cap 70 can be used as a mount for solar panels, etc.

[0034] To reinforce the fit between the lower end 72 of the shingle bar cap and the raised portion 52 of the channel plate, adhesive means 75 may be added to the fit, as shown in Figure 3. Adhesive means include applying and filling an adhesive such as a polyurethane resin, fastening with rust-resistant nails, screws, or bolts, or applying tape to the lower end of the fit (adhesive is used in Figure 3). The adhesive also functions as a caulking material (filler) between the retaining clip 60 and the shingle bar cap 70, contributing to an expansion of the tolerance for dimensional accuracy of the shingle bar cap 70.

[0035] In the third embodiment shown in Figure 4, the lower end 72 of the shingle bar cap extends all the way to the bottom plate portion 51 of the groove plate, and horizontal portions 73 extend from both ends in directions separating them. These horizontal portions 73 form a flange for tight contact with the bottom plate portion 51 of the groove plate. In this embodiment, the tight contact portion is spaced apart from the shingle bar portion 20, making it even more difficult for rainwater to penetrate. Furthermore, the ease of spray painting the area around the shingle bar with waterproof paint such as polyurethane resin is greatly improved.

[0036] The means for tightly adhering the horizontal portion 73 of the shingle rod cap to the bottom plate portion 51 of the groove plate is also not particularly limited. Examples of adhesion methods include applying a polyurethane resin adhesive, fastening with rust-resistant nails, screws, or bolts, or applying tape to the horizontal portion 73. Adhesives are preferred, and polyurethane resins, epoxy resins, etc. are particularly preferred.

[0037] The present invention also provides a method for constructing a tiled roof. The construction process is the same as that of conventional tiled roofs, from laying sheathing boards over the entire roof surface on top of the roof rafters and securing them in place to laying a waterproof sheet such as asphalt roofing over the entire roof. The differences from the conventional method are explained below. As described above, polyurethane resin is molded according to the shape of the tiled roof cap 70 prior to on-site construction. Being able to perform the molding work indoors is advantageous in reducing the burden of on-site construction, which is easily affected by weather. Furthermore, conventional metal tiled roof caps are procured on-site, which means that the finish, such as lifting, is prone to variation after construction. In contrast, the present invention uses an injection molding machine or the like to provide tiled roof caps with consistent shape and quality.

[0038] At the site where a tile roof is being constructed, as shown in Figure 5, a through retaining clip 60 is inserted into the gap 54 between adjacent grooves, and the through retaining clip is fixed to the base material 11 by nailing or the like. The horizontal portion 53 of the groove and the horizontal portion 61 of the through retaining clip are crimped together, and the crimped portion is bent downward at a right angle around its base end to prevent springback, forming a folded portion 56 of the groove and a folded portion 63 of the through retaining clip that is in close contact with the outside of the folded portion 56.

[0039] The shingle rod cap 70 is fitted into the raised portion 52 of the groove plate. The fitting operation is very simple and the finished quality is consistent.

[0040] To reinforce the fit between the lower end 72 of the shingle rod cap and the raised portion 52 of the groove plate, adhesive means 75 are added to the fitting area as shown in Figure 3. When horizontal portions 73 are provided as crocodile portions on both ends of the shingle rod cap 70, the horizontal portions 73 and the bottom plate portion 51 are adhered to each other with adhesive or the like.

[0041] The present invention also provides a waterproofing method for the above-mentioned tiled roof. The waterproofing process after construction of the tiled roof is described below. The entire tiled roof 1 obtained using the above-mentioned tiled roof construction method, including the tiled roof caps 70, is painted with a waterproof paint. Because the entire roof, including the tiled roof caps, does not have a complex structure that makes painting difficult, the on-site spraying work is simpler than before, and there is no variation in the paint application by craftsmen.

[0042] The waterproof paint may be a water-based paint or an organic solvent-based paint, examples of which include polyurea resin, polyurethane resin, acrylic resin, acrylic urethane resin, silicone resin, etc. Polyurea resin paint is a two-component water-based paint made of isocyanate and polyamine. Polyurethane resin paint is a one-component or two-component water-based paint made of polyol and polyisocyanate. The waterproof paint is preferably a polyurea resin paint or a urethane resin paint, more preferably a polyurea resin. The application method may be any of spray, roller, brush application, etc., depending on the application location and paint. [Explanation of symbols]
