Description

Technical Field

[0001] The present invention relates to a roof ridge structure, a ridge member used for the ridge structure, and a method for constructing a ridge.

Background Art

[0002] Patent Document 1 discloses a structure of a ridge in which a drain plate having a gutter groove recessed along the ridge is attached to the ridge, and each roof plate disposed on both sides with the ridge interposed therebetween is attached such that the ridge-side end thereof is positioned on the gutter groove of the drain plate, and a waterproof material is stretched across the upper surfaces of the ridge-side ends of the roofing materials disposed with the ridge interposed therebetween, and a ridge wrapping is attached across the upper surfaces of the ridge-side ends of the roofing materials from above the waterproof material.

[0003] Specifically, on the upper side of a long waterproof material fixed along the extending direction of the ridge, a fixing metal fitting having an inverted V-shaped cross section is installed along the roof surface, and a ridge wrapping having the same inverted V-shaped cross section is fixed by engaging a locking piece at the eaves-side end thereof with a locking receiving piece at the eaves-side end of the fixing metal fitting.

[0004] These fixing metal fittings and the ridge wrapping are formed at the same inner angle as the angle formed by the roof surfaces on both sides of the ridge. When fixing the ridge wrapping, the locking piece on one side at the eaves is engaged with one locking receiving piece of the fixing metal fitting, and then the other locking piece is lowered from above and engaged with the other locking receiving piece so as to cover the fixing metal fitting with the ridge wrapping.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the building structure of Patent Document 1, when locking the other locking piece of the building wrap from above to below the other locking receiving piece of the fixing fitting, depending on the shape, it may be difficult to fit, and there is a problem that the construction is time-consuming.

[0007] An object of the present invention is to provide a building structure, a building member, and a building construction method with good workability.

Means for Solving the Problems

[0008] The building structure according to the present invention includes roofing materials provided on both sides with the building in between, a base material fixed on the building and the roofing materials on both sides thereof, and a cover material attached to the base material and covering the building and the roofing materials on both sides. The cover material has an inverted V-shaped cross section, the inner angle formed by the bent portion is smaller than the angle formed by the roofing materials on both sides, and a space is formed between the bent portion and the building.

[0009] The building member according to the present invention includes the base material and the cover material of the building structure.

[0010] The building construction method according to the present invention is a method for constructing the building structure, including a step of fixing the base material on the roofing materials on both sides of the building, a step of attaching one end of the cover material to the eaves side end of the base material on one side of the roofing material, a step of pressing the bent portion of the cover material against the other side of the roofing material with one end of the cover material attached to the eaves side end of the base material, and a step of attaching the other end of the cover material to the eaves side end of the base material by the restoring force of the cover material in a state where the other end of the cover material exceeds the eaves side end of the base material on the other side of the roofing material.

Effects of the Invention

[0011] Since a space is formed between the bent portion of the cover material and the ridge in the ridge structure according to the present invention, with one eaves-side end of the cover material attached to one eaves-side end of the base material, it is possible to press the bent portion against the other eaves side. Further, since the inner angle of the bent portion is smaller than the inner angle formed by the roof material, a restoring force acts, and the other eaves-side end of the cover material is attached to the other eaves-side end of the base material, making the attachment work easier.

Mode for Carrying Out the Invention

[0013] (Embodiment) -Ridge Structure- FIG. 1A shows the ridge structure of the present embodiment. The building having the ridge structure of the present embodiment is, for example, a residential building where people live. In addition to residential buildings, the building may be a non-residential building such as a store, factory, or warehouse.

[0014] A building having the gable roof structure of this embodiment forms a gable roof and has two roof surfaces 2 sandwiching the ridge 1. In this embodiment, on each roof surface 2 (the upper surface of the roof), the side where the ridge 1 is located is defined as the "ridge side", and the side opposite to the ridge is defined as the "eave side". Also, two directions, the direction from the ridge side to the eave side and the direction from the eave side to the ridge side on each roof surface 2, are defined as the eave-ridge direction. Note that the roof having the gable roof structure of this embodiment is not limited to a gable roof.

[0015] On each roof, a sheathing board 3 is installed on a plurality of purlins (not shown), and an underlayment 4 is laid on the sheathing board 3. The underlayment 4 is laid across the sheathing board 3 that constitutes the roof surface 2A to the sheathing board 3 that constitutes the ridge 1 and the roof surface 2B. And a plurality of roofing materials 5 are laid on the sheathing board 3 and the underlayment 4 of each roof surface 2. The underlayment (waterproof sheet) 4 is, for example, a synthetic polymer-based underlayment or asphalt roofing (including asphalt felt and modified asphalt roofing). Although not shown in the figure, the underlayment 4 is laid double on the upper surface of the gable side of the sheathing board 3. That is, on the upper surface of the gable side of the sheathing board 3 on which the underlayment 4 is laid, an underlayment 4 with a predetermined width (for example, 1,000 mm) is laid so as to extend in the eave-ridge direction.

[0016] Each roofing material 5 is, for example, a slate tile, and is manufactured by molding a cement-based molding material and curing it.

[0017] On both sides of the ridge 1, both roof surfaces 2A and 2B are configured to form an interior angle α, and a ridge member 7 is installed at the ridge 1 and its peripheral part. This ridge member 7 has functions such as preventing rainwater from entering from the ridge 1.

[0018] The ridge member 7 includes a waterproof tape 6 that waterproofs the ridge 1 and its peripheral part, a base material 8 fixed to the roof surface 2, and a cover material 9 attached to the base material 8 and covering the ridge 1 and its peripheral part.

[0019] The waterproof tape 6 is a butyl rubber-based waterproof tape with excellent weather resistance, an acrylic-based waterproof tape with excellent workability that is easy to cut by hand, or a waterproof hand tape based on a polyester non-woven fabric, etc. It is affixed from the upper surface of the building-side end of the roofing material 5 on one side roof surface 2A sandwiching Building 1 across the upper surface of the building-side end of the roofing material 5 of Building 1 and the other side roof surface 2B. Note that waterproof materials other than the waterproof tape 6 may be used. For example, a soft sponge with closed cells formed in a tape shape may be used.

[0020] The base material 8 is made of sheet metal and is a long member extending along Building 1. It has a reverse V-shaped cross-section, and the inner angle of its bent portion 8B is substantially the same as the inner angle α formed by both roof surfaces 2A and 2B. The base material 8 has a fixing portion 8A fixed on the building-side end of the roofing material 5 and a pair of attachment portions 8C provided at the eaves-side end of the fixing portion 8A to which the cover material 9 is attached (see FIG. 1B).

[0021] The fixing portion 8A has a reverse V-shaped cross-section, and fixing holes through which fixing tools 11 such as screws are inserted are formed at both eaves-side ends thereof. Each attachment portion 8C has an inclined piece 8D extending in a direction away from the roofing material 5 from the eaves-side end of the fixing portion 8A toward the eaves side, and an attachment piece 8E extending along the upper surface of the roofing material 5 from the eaves-side end of the inclined piece 8D. The inner angle γ formed by the fixing portion 8A and the inclined piece 8D is, for example, 91 degrees or more and 179 degrees or less. Since the inclined piece 8D is inclined with respect to the upper surface of the roofing material 5 in this way, when a load acts on the attachment piece 8E from above, the attachment piece 8E is likely to be displaced in a direction perpendicular to the upper surface of the roofing material 5. The tip of the attachment piece 8E is hemmed and folded to the front side so that the tip faces the building side.

[0022] The fixing portion 8A is fixed on the waterproof tape 6, and the eaves-side end of the waterproof tape 6 extends further toward the eaves side than the eaves-side end of the fixing portion 8A. Also, an adhesive 12 is provided on the head of the fixing tool 11. This adhesive 12 adheres to the back surface of the cover material 9 to firmly fix the cover material 9 and suppresses rainwater from entering the holes formed in the roofing material 5 and the field board 3 by the fixing tool 11. Therefore, the adhesive 12 is preferably insoluble in water.

[0023] The cover material 9 is made of sheet metal, is a long member extending along the building 1, and has an inverted V-shaped cross section. The inner angle β formed by the bent portion 9B of the cover material 9 is smaller than the inner angle α formed by the roof materials 5 on both sides of the building 1. Also, there is a gap between the bent portion 9B and the bent portion 8B of the base material 8, and a space 10 is formed between the cover material 9 and the base material 8. Specifically, this space 10 is formed such that the vertical dimension gradually decreases from the bent portion 9B toward the eaves side when viewed from the extending direction of the building 1.

[0024] The cover material 9 has a cover material main body 9A with an inverted V-shaped cross section and a pair of attachment pieces 9C that are folded back toward the building side on the back side of the cover material main body 9A from both eaves-side ends of the cover material main body. The attachment piece 9C is attached so as to be inserted into the space between the attached piece 8E of the base material 8 and the roof material 5, and the attached piece 8E of the base material 8 is sandwiched vertically by the cover material main body 9A and the attachment piece 9C. The inner angle formed by the cover material main body 9A and the attachment piece 9C is, for example, 5 degrees or more and 90 degrees or less.

[0025] - Construction method - Next, a method for constructing the building structure with the above configuration will be described with reference to FIGS. 2 to 6.

[0026] With the roof material 5 constructed from the eaves tip (not shown) to the building and the ridge board not yet constructed, first, the waterproof tape 6 is attached across from the upper surface of the building-side end of the roof material 5 on one side across the building 1 to the upper surface of the building-side end of the roof material on the other side (see FIG. 2). At this time, it is preferable that the dimension of the waterproof tape 6 from the building 1 to the eaves side end is larger than the dimension of the fixing portion 8A of the base material 8 from the building 1 to the eaves side end.

[0027] Next, the base material 8 is installed above the waterproof tape 6 (see FIG. 3). At this time, the bent portion 8B of the base material 8 is installed at a position that coincides with the building 1.

[0028] Next, fix the fixing portion 8A of the base material 8 with a fixture 11 (see Fig. 4). The fixture 11 is, for example, a screw, and in this embodiment, it penetrates through the three roof materials 5 and the underlayment 4 laminated vertically and reaches the floor board 3.

[0029] Next, apply an adhesive 12 so as to cover the entire head of each fixture 11 (see Fig. 5). At this time, from the viewpoint of waterproofing, it is preferable to apply the adhesive 12 over an area larger than the head of the fixture 11.

[0030] Then, insert the mounting piece 9C on one side of the cover material 9 under the mounted piece 8E on one side of the base material 8, and attach the eaves side end of one side of the cover material 9 to the eaves side end of one side of the base material 8 (see Fig. 6A).

[0031] Next, with the mounting piece 9C on the other side of the cover material 9 in a free state not attached to the mounted piece 8E on the other side of the base material 8, press the bent portion 9B of the cover material 9 against the mounted piece 8E on the other side. This pressing operation is performed until the mounting piece 9C on the other side of the cover material 9 reaches the eaves side of the mounted piece 8E on the other side.

[0032] After that, when the pressing operation is stopped, since the inner angle β of the bent portion 9B of the cover material 9 is smaller than the inner angle α formed by the roof materials 5 on both sides of the ridge 1, the restoring force of the cover material 9 acts, and the mounting piece 9C on the other side is inserted and attached to the back side of the mounted piece 8E on the other side (see Fig. 6B).

[0033] (Modification example) The embodiment described above can be appropriately modified in design.

[0034] This embodiment is an application of the ridge structure according to the present invention to a large building, but is not limited thereto, and it may be applied to a corner building.

[0035] In this embodiment, the base material 8 is composed of one member, but is not limited thereto, and it may be composed of a pair of members. In this case, the members are installed on each of the roof materials 5 on both sides of the ridge 1.

[0036] In this embodiment, the base material 8 is a long member extending along the building 1, but it is not limited to this, and it may be a short member. In this case, the short members are arranged at intervals along the building 1.

[0037] In this embodiment, the waterproof tape 6 is provided, but it may not be provided. When the waterproof tape 6 is not provided, the base material 8 is preferably in a long shape covering the entire building 1.

[0038] In this embodiment, the adhesive 12 is provided, but it may not be provided.

[0039] (Aspect) The first aspect includes a roofing material 5 provided on both sides with the building 1 in between, a base material 8 fixed on the building 1 and the roofing materials 5 on both sides thereof, and a cover material 9 attached to the base material 8 and covering the building 1 and the roofing materials 5 on both sides. The cover material 9 has a reverse V-shaped cross section, and the inner angle β formed by the bent portion 9B is smaller than the angle α formed by the building 1, and a space 10 is formed between the bent portion 9B and the building 1.

[0040] According to the first aspect, since the space 10 is formed between the bent portion 9B of the cover material 9 and the building 1, it is possible to press the eaves-side end portion on one side of the cover material 9 against the eaves-side end portion on one side of the base material 8, and further, since the inner angle β of the bent portion 9B is smaller than the inner angle α formed by the roofing material 5, a restoring force acts, and the eaves-side end portion on the other side of the cover material 9 is attached to the eaves-side end portion on the other side of the base material, so that the attachment work becomes easy.

[0041] The second aspect is that, in the first aspect, the base material 8 has an inverted V-shaped cross section, and includes a fixing portion 8A fixed on the roof material 5, and a pair of attachment portions 8C provided at the eaves-side end of the fixing portion 8A to which the cover material 9 is attached. Each attachment portion 8C has an inclined piece 8D that extends upward as it goes from the fixing portion 8A toward the eaves side, and an attachment piece 8E that extends along the upper surface of the roof material 5 from the eaves-side end of the inclined piece 8D. The cover material 9 has a cover material main body 9A with an inverted V-shaped cross section, and a pair of attachment pieces 9C that are folded back from the eaves-side end of the cover material main body 9A to the ridge 1 side on the back side of the cover material main body 9A and are attached to the attachment piece 8E.

[0042] According to the second aspect, since the inclined piece 8D of the base material 8 is inclined with respect to the upper surface of the roof material 5, the attachment piece 8E at the tip of the inclined piece 8D is likely to be displaced in a direction perpendicular to the upper surface of the roof material 5. Therefore, the resistance force when attaching the attachment piece 9C on the other side of the cover material 9 is not large, and the attachment work becomes easy.

[0043] The third aspect is that, in the second aspect, it further includes a waterproof tape 6 provided across the ridge 1 and the other roof material 5 from one roof material 5 on the back side of the base material 8, and the waterproof tape 6 extends to the eaves side of the fixing portion 8A.

[0044] According to the third aspect, since the waterproof tape 6 is provided up to the eaves side rather than the fixing portion 8A of the base material 8, even if rainwater enters the back side of the fixing portion 8A, it is difficult for water to enter the field board 3 or the like.

[0045] The fourth aspect is that, in the first aspect, the base material 8 is a long member extending along the ridge 1.

[0046] According to the fourth aspect, it becomes possible to construct the cover material 9 linearly along the ridge 1.

[0047] The ridge member 7 of the fifth aspect includes the base material 8 and the cover material 9 of the ridge structure in any one of the first to fourth aspects.

[0048] According to the fifth aspect, it is possible to achieve the operational effects of the first to fourth aspects.

[0049] The sixth aspect is a method of constructing the building structure of the first aspect, including the steps of fixing the base material 8 on the roof materials 5 on both sides of the building 1; attaching one end of the cover material 9 to the eaves-side end of the base material 8 on one side of the roof material 5; pressing the bent portion 9B of the cover material 9 against the other side roof material 5 with one end of the cover material 9 attached to the eaves-side end of the base material 8; and attaching the other end of the cover material 9 to the eaves-side end of the base material 8 on the other side roof material 5 beyond the eaves-side end of the base material 8 by the restoring force of the cover material 9.

[0050] According to the sixth aspect, it is possible to achieve the operational effects of the first aspect.
