Description

[Technical Field]

[0001] The present invention relates to a hollow roof structure that is installed on top of a roof. [Background technology]

[0002] For the ridge structure installed on the ridge beam, clay was piled directly on the sheathing boards installed on the rafters above the roof purlin, and then noshi tiles were stacked on top of them. A cap tile was then placed on top and secured with ridge soil, and the noshi tiles and cap tile were secured together by the ridge soil drying and hardening. In other words, in the completed ridge structure, the noshi tiles and cap tile are not secured with nails or other fasteners. Therefore, traditional ridge structures were vulnerable to vibrations from typhoons and earthquakes, and there were many cases where the cap tiles and noshi tiles at the ridge were peeled off and fell off the ridge soil, causing the ridge soil to collapse. Furthermore, over time, the ridge soil weathered, resulting in further weakening.

[0003] Furthermore, because this construction method uses a large amount of earth for the ridge, the ridge is constantly subjected to an extremely large load. As a result, there have been many confirmed cases of houses collapsing after an earthquake. For example, in the Noto Peninsula earthquake that occurred on January 1, 2024, many houses collapsed. Furthermore, even in houses that escaped collapse, damage to the ridge structure has been confirmed in many cases.

[0004] In order to restore the ridge structure damaged by an earthquake or other cause to its current state, it is necessary to procure a large number of noshi-gawara and kanmuri-gawara tiles. However, these materials are not currently mass-produced, and procuring them will take a long time. Furthermore, even if these materials could be procured quickly, restoring the ridge structure would be extremely difficult due to the complex process involved. In addition, there is an overwhelming shortage of workers capable of carrying out repair work. Taking all of these facts into consideration, it is believed that early restoration will be difficult.

[0005] Patent Document 1 proposes an earthquake-resistant ridge that improves earthquake resistance by reducing the weight of the ridge, improves waterproofing by reducing the number of joints in the structure, and also gives the ridge tiles functionality such as emergency messages and lighting. The earthquake-resistant ridge has a hollow cross section, and an upper coping part with an integrated bottom and side structure is detachably attached, and is fixed to the tiles while placed directly on the roof substrate via a mounting structure.

[0006] Patent Document 2 proposes a ridge tile installation structure that allows ridge tiles to be reliably and easily positioned regardless of the roof slope when laid, and allows the ridge tiles to be easily attached to the ridge of the roof once positioned, resulting in a beautiful and inexpensive appearance when the ridge tiles are installed. The ridge tile installation structure consists of a ridge tile body that covers the upper part of the ridge and mounting sections provided on both end sections of the ridge tile body. Support sections that protrude approximately downward are provided on both sides of the back surface of the ridge tile body. Both support sections are positioned inward from the driving-in section. Abutment sections are formed on the outer surfaces of both support sections that slope inward the further they extend downward. Both mounting sections of the ridge tile are placed on the uppermost roof tiles, and any position on both sloped abutment sections is abutted against the upper corners of the ridge sides of both copings. Fasteners driven into the driving-in sections of the ridge tile body are fixed to both copings. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-198981 [Patent Document 2] Japanese Patent Application Laid-Open No. 2004-150041 Summary of the Invention [Problem to be solved by the invention]

[0008] However, the earthquake-resistant ridge proposed in Patent Document 1 requires the installation structure to be fabricated each time to match the slope of the roof underlayment, making it difficult to fabricate in a short period of time. Furthermore, it cannot accommodate construction errors in the roof underlayment, which could result in large gaps between the roof underlayment and the installation structure. The ridge tile installation structure proposed in Patent Document 2 involves driving fasteners into the ridge tile body through its insertion hole and fastening it to both copings, which raises concerns about weakening the strength of the ridge tile body. Furthermore, there is a risk of rainwater seeping in through the insertion hole.

[0009] The present invention has been made with an eye on these problems, and aims to provide a hollow ridge structure that can be easily attached to a ridge in a short period of time and has excellent durability and earthquake resistance. [Means for solving the problem]

[0010] The invention to solve the above problem is a hollow ridge structure installed at the top of a roof, which is installed along both sloping surfaces of the sheathing section and is equipped with a support section that is fixed to the sheathing section, a ridge body that protrudes from the support section, and a connecting section that flexibly connects the support section and the ridge body, and is characterized in that the support section has a pair of support plates and a hinge section that rotatably connects the pair of support plates, and the support section, ridge body, and connecting section work together to define a hollow section.

[0011] With this configuration, the support sections, which are installed along both sloped surfaces of the sheathing boards and fixed to the sheathing boards, have a pair of support plates and hinge sections that rotatably connect the pair of support plates, and the ridge body and support sections are flexibly connected, so the hollow ridge structure can be easily installed on a roof in a short time by simply rotating the support plates within a predetermined range of roof slope.In addition, the support sections, ridge body, and connecting sections work together to define the hollow section, making it possible to reduce the weight of the hollow ridge structure.

[0012] Preferably, the support plate is provided with a driving portion located on the outside of the hollow portion, and the support plate and the sheathing board portion are fixed to each other by driving a fastener into the driving portion.

[0013] According to this configuration, the fasteners for fixing the support plate and sheathing board section are driven into the driving section located on the outside of the hollow section, and can therefore be easily driven in from the outside of the ridge body.

[0014] Preferably, a drip-proof board is provided to prevent rainwater from entering the space, and one end of the drip-proof board is fitted into a connection portion provided in the middle of the ridge body, and the other end is in contact with the roof tile.

[0015] With this configuration, the hollow ridge structure is equipped with a water-repellent board, which prevents rainwater from entering the hollow space. In addition, one end of the water-repellent board fits into a connector provided in the middle of the ridge body, and the other end contacts the roof tiles, so the ridge body can be installed on the peak of the roof without attaching the water-repellent board, which improves workability.

[0016] Preferably, the connection portion is provided with a recess extending in the longitudinal direction, the recess being defined by a first connection plate extending in the longitudinal direction and a second connection plate located below the first connection plate and extending in the longitudinal direction parallel to the first connection plate, and the drip-water plate is provided with an insertion portion that is inserted into the recess.

[0017] According to this configuration, the connection portion has a recess extending in the longitudinal direction, and the recess is defined by a first connection plate extending in the longitudinal direction and a second connection plate located below the first connection plate and extending in the longitudinal direction parallel to the first connection plate, and the drip-water plate has an insertion portion that is inserted into the recess, making it easy to insert the drip-water plate into the connection portion.

[0018] Preferably, the first connecting plate and the dripping plate have upper surfaces that are substantially flush with each other.

[0019] With this configuration, the top surfaces of the first connecting plate and the drip-water plate are substantially flush with each other, so that rainwater that falls on the ridge body can flow smoothly down to the roof.

[0020] Preferably, the outer surface of the ridge body is decorated to resemble a ridge tile.

[0021] According to this configuration, the outer surface of the ridge body is decorated to resemble ridge tiles, giving the hollow ridge structure an aesthetically pleasing appearance. [Brief explanation of the drawings]

[0022] [Figure 1] FIG. 1 is a schematic perspective view of a hollow-core structure. [Figure 2] FIG. [Figure 3] FIG. [Figure 4] This is a modified example of the connecting portion. DETAILED DESCRIPTION OF THE INVENTION

[0023] Hereinafter, an embodiment of the hollow core structure of the present invention will be described in detail with reference to FIGS.

[0024] As shown in FIG. 1 , the hollow ridge structure 1 is installed on the peak 101 of the roof 100 and includes a support member 10 and a ridge body 20. In this embodiment, the peak 101 of the roof 100 is illustrated as a ridge, but this is not limited to this and may be a corner ridge. The support member 10 and the ridge body 20 are flexibly connected via a connecting member 30, and the support member 10, ridge body 20, and connecting member 30 cooperate to define a hollow space 50. Furthermore, a water-repellent board 70 is provided to prevent rainwater from entering the hollow space 50. One end of the water-repellent board 70 is detachably fitted to a connecting member 25 provided in the middle of the ridge body 20. The other end of the water-repellent board 70 contacts a roof tile 105.

[0025] The sheathing board portion 110 has a sheathing board 111 and an adjusting board 112. At the top 101 of the roof 100, the adjusting board 112 is stacked and fixed on top of the sheathing board 111. The tip of the adjusting board 112 is connected to a roof tile 105. In addition, the roof tile 105 is supported by the sheathing board 111.

[0026] The support unit 10 includes a pair of support plates 11 and a hinge unit 15 that rotatably connects the support plates 11. The support plate 11 is a plate member extending in the longitudinal direction L1. The hinge unit 15 is a hinge-structured member that extends in the longitudinal direction L1, similar to the support plate 11. By rotating the support plate 11 and adjusting the angle between the support plates 11, the support plate 11 comes into surface contact with the adjustment plate 112. The support plate 11 is fixed to the adjustment plate 112 by a fixture 60. The support plate 11 and the hinge unit 15 are preferably made of a material that is strong and not susceptible to deterioration due to rust. Specific examples include, but are not limited to, stainless steel and copper. In this embodiment, the longitudinal direction L1 refers to the direction in which the top 101 of the roof 100 extends.

[0027] The support plate 11 is provided with a driving portion 12, and by driving a fastener 60 into the driving portion 12, the support plate 11, the sheathing board 111, and the adjustment plate 112 are fixed to each other. The driving portion 12 is provided on the outside of the hollow portion 50.

[0028] The ridge body 20 is a plate-like member with a bowl-shaped cross section extending along the longitudinal direction L1, and is connected to the support plate 11 via a connecting portion 30. The supporting portion 10, ridge body 20, and connecting portion 30 work together to define a hollow portion 50. By providing a hollow portion 50 in the hollow ridge structure 1, it is possible to significantly reduce the weight compared to general ridge tiles, which have a solid structure. This makes it possible to make the house and ridge structure less susceptible to damage in an earthquake.

[0029] The outer surface of the ridge body 20 is decorated to resemble ridge tiles. This allows the roof tiles 105 and hollow ridge structure 1 to create an appearance similar to the large ridge commonly seen in Japanese houses. The decoration applied to the ridge body 20 may be done by painting the ridge body 20 in a color similar to ridge tiles, or by attaching tile pieces to the outer surface. Alternatively, the outer surface may be molded into a shape similar to a ridge tile and then painted in a color similar to a ridge tile. The ridge body 20 is preferably made of a lightweight, strong material. A specific example is FRP, but the material is not limited to this.

[0030] The water-repellent board 70 is an irregularly shaped plate-like member whose cross section extending along the longitudinal direction L1 is an L-shape rotated approximately 90 degrees, and one end fits into a connecting portion 25 provided in the middle of the ridge body 20 via a recess 26 described below, and the other end contacts the surface of the roof tile 105 via a contact portion 73 described below. By attaching the water-repellent board 70 to the ridge body 20, the connecting portion 25 can be prevented from being exposed to the outside space, thereby preventing deterioration of the connecting portion 25. It also prevents rainwater from entering the hollow portion 50.

[0031] It is preferable to seal any gaps that may occur between the roof tiles 105 and the water dripping board 70 using a sealant. Examples of sealants include, but are not limited to, silicone-based, modified silicone-based, urethane-based, and acrylic-based sealants. This prevents rainwater from entering the hollow portion 50. It is preferable that the water dripping board 70 be made of a lightweight, strong material. Specifically, it is made of, but is not limited to, FRP.

[0032] As shown in FIG. 2, the flashing board 70 is composed of a fitting portion 71, an inclined portion 72, and a contact portion 73. The fitting portion 71 and the contact portion 73 are connected via the inclined portion 72. The fitting portion 71 is fitted into the recess 26 as described below. This fitting portion 71 may be detachably fitted into the recess 26. The recess 26 is provided in the connection portion 25 located in the middle of the ridge body 20. The fitting portion 71 and the inclined portion 72 are located above the roof 100 and extend along the slope of the roof 100 in a cross-sectional view. The inclination angles of the fitting portion 71 and the inclined portion 72 are preferably set to be the same as or slightly larger than the slope angle of the roof 100. The contact portion 73 extends from the tip of the inclined portion 72 toward the roof 100, and its tip contacts the roof tile 105.

[0033] The connecting portion 25 defines a recess 26 extending in the longitudinal direction L1. Specifically, the recess 26 is defined by a first connecting plate 21 extending in the longitudinal direction L1 and a second connecting plate 22 located below the first connecting plate 21 and extending in the longitudinal direction L1 while being parallel to the first connecting plate 21. The inclination angles of the first connecting plate 21 and the second connecting plate 22 are preferably set to be the same as or slightly larger than the inclination angle of the roof 100.

[0034] The thickness of the fitting portion 71 is set to be thinner than the thickness of the inclined portion 72. This thickness corresponds to the thickness of the first connecting plate 21. This allows the top surfaces of the first connecting plate 21 and the inclined portion 72 to be substantially flush. It is preferable to seal any gaps that may occur between the first connecting plate 21 and the inclined portion 72 with a sealant. Examples of sealants include, but are not limited to, silicone-based, modified silicone-based, urethane-based, and acrylic-based sealants.

[0035] As shown in Figure 3, a protrusion 27 is provided at the end of the ridge body 20. The protrusion 27 is located at the end of the ridge body 20 and extends outward. The protrusion 27 is connected to the support plate 11 via a filler 36 filled in the filling recess 35.

[0036] The filling recess 35 is a space defined by the first filling plate 31, the second filling plate 32, the opposing plate 33, and the support plate 11. The first filling plate 31 is a plate-like member extending along the longitudinal direction L1, and one end is connected and fixed to the support plate 11. The opposing plate 33 is a plate-like member connected and fixed to the tip end of the first filling plate 31, and is located above the protruding portion 27 and opposed to the protruding portion 25.

[0037] By providing the opposing plate 33 opposite the protruding portion 27, the ridge body 20 can be prevented from falling out of the filling recess 35. For example, when the ridge body 20 tries to float up due to the influence of strong winds, the protruding portion 27 comes into contact with the opposing plate 33, thereby preventing the ridge body 20 from floating up. The opposing plate 33 may be installed over the entire length of the first filling plate 31, or multiple opposing plates 33 may be installed at predetermined intervals.

[0038] The second filler plate 32 is a plate-like member extending along the longitudinal direction L1, and one end thereof is connected and fixed to the support plate 11.

[0039] The filling recess 35 accommodates the protruding portion 27 and is filled with a filling material 36. The filling material 36 is used to flexibly connect the support portion 10 and the ridge main body 20 at the connecting portion 30. In this case, the ridge main body 20 is able to flexibly deform (elastically deform) in all directions (non-directional) relative to the support portion 10 via the filling material 36. As a result, the vibrations of the ridge main body 20 and the support portion 10 are absorbed and mitigated by the filling material 36, contributing to earthquake resistance. Note that the filling material 36 is preferably an elastic body with flexibility, and specific examples include, but are not limited to, vulcanized rubber and flexible epoxy resin.

[0040] The procedure for installing the hollow-core structure 1 on the main building will be explained.

[0041] The support plate 11 is placed on the adjusting plate 112 and rotated so that the underside of the support plate 11 is in surface contact with the upper surface of the adjusting plate 112. The drip-proof board 70 is removed at this time. After confirming that the underside of the support plate 11 is in surface contact with the upper surface of the adjusting plate 112, fasteners 60 are driven into the driving sections 12 to secure the support plate 11 to the sheathing board section 110. Driving multiple fasteners 60 into the driving sections 12 at predetermined intervals firmly secures the support plate 11 to the sheathing board section 110. It is preferable that the fastening strength between the support plate 11 and the sheathing board section 110 be sufficient to prevent the hollow-frame structure 1 from being blown away under a predetermined wind speed. The predetermined wind speed may be determined appropriately taking into account the maximum wind speed expected at the installation location of the hollow-frame structure 1, the importance of the house, etc.

[0042] After the installation of the ridge body 20 is complete, the drip-proof board 70 is attached. The shape of the drip-proof board 70 is set so that it can contact the roof tiles within the expected range of inclination angles of the roof 100. The drip-proof board 70 is attached to the ridge body 20 by inserting and fitting the fitting portion 71 into the recess 26 defined by the connecting portion 25. At this time, the end of the drip-proof board 70 is in a state where it presses against the roof tiles 105.

[0043] It is conceivable that gaps may occur between the roof tiles 105 and the flashing board 70 due to unevenness in the surface of the roof tiles 105 or errors in the precision of the flashing board 70. If a gap is found between the roof tiles 105 and the flashing board 70, it is preferable to fill the gap with a sealant.

[0044] Furthermore, if a gap is found between the first connecting plate 21 and the inclined portion 72, it is preferable to fill the gap with a sealing material in the same way.

[0045] This embodiment is merely an example, and it goes without saying that modifications can be made without departing from the technical spirit of the present invention. For example, the configuration of the connecting portion 30 may be a flexible connecting structure in which the filler 236 is sandwiched between the protruding portion 27 and the support plate 11, connected and fixed, as shown in Figure 4. [Industrial Applicability]

[0046] The hollow building structure of the present invention has great potential for industrial use because it allows for rapid restoration of the building when it is damaged by an earthquake or the like. [Explanation of symbols]
