Description

The present invention relates to a roof base structure, particularly a tile roof base structure.

The roof is a structure that covers the upper part of the building and has the role of protecting the house from rain, wind, snow, and sunlight. Japan is characterized by a hot and humid climate and a large amount of rainfall, and the roofs of houses are generally or traditionally tiled. Roof tiles have excellent water resistance, nonflammability, durability, and heat insulation, and because an air layer is created between the roof tiles and the base of the roof, there are advantages such as resistance to moisture retention, condensation, and outside air heat. There is.

In the case of a wooden house, the base structure of the roof is generally such that a bundle is erected on a beam and the main building (haze) is passed horizontally, and the flow direction of the roof is from the purlin to the nose main building or the eaves girder. Rafters of square lumber are hung at regular intervals, and a field board is nailed on the rafters and stretched horizontally to form the base of the roof. A waterproof paper (roofing) is laid on the entire surface of the field board, and a square lumber hooking rail is horizontally passed over the waterproof paper according to the position of the rafters, nailed, and the tile is hung on the hooking rail. I try to layer the roof tiles.

However, if rainwater that has flowed through the gaps between the tiles and between the roof bases tries to flow over the waterproof paper, it may be blocked by the hook rails and cause rain leaks. A proposal is known in which a plurality of grooves are provided at equal intervals to facilitate the flow of rainwater through the grooves (Patent Document 1).

In addition, in order to make it easier for rainwater to flow toward the eaves, a narrow thin plate material called wood shaving is installed between the waterproof paper and the hook rail on it according to the position of the rafters, and the waterproof paper and the hook rail are connected. It is known that a gap is formed between them so that rainwater can be caught and flowed from under the crosspiece toward the eaves.

This base structure is composed of both carpenters and tilers, but there is a fundamental problem in that they do not discuss anything about leaks and work according to each occupation in their own way. .. In other words, the current situation is that the construction is being carried out with the basic part of where the problem is and how to solve it unsolved.

Japanese Unexamined Patent Publication No. 2000-87513

The proposal of Patent Document 1 is to provide a groove in a part of the tile pier, but there is a concern that the amount of rainwater blocked by the tile pier increases during heavy rain and the rainwater overflows to the roof base. A structure in which a gap is provided between the hook rail and the waterproof paper using a wooden shaving has the advantage that rainwater can easily flow smoothly on the waterproof paper, but there is a problem that rain leakage cannot be sufficiently prevented as described below. ..

First, when pasting waterproof paper on a field board, a tool called a hammer cutter is used to drive in a metal object called staples, but if the waterproof paper is pasted roughly, the waterproof paper is easily scratched and rainwater may leak from here. be. Secondly, the wood shavings are nailed from the top of the waterproof paper to the rafters, and the hooks are nailed from above, but at that time, a nail hole is opened in the waterproof paper, and rainwater comes from here. Often leaks.

Thirdly, the hook rail is in a state where a heavy roof tile is placed on the hook rail where a gap is created by inserting a wood scraper between the hook rail and the waterproof paper. For this reason, over the years, the hook bar is pressed and bent, and that part comes into contact with the waterproof paper. In such a state, when a strong wind such as a typhoon blows, the tiles are shaken up and down due to the influence, and at this time, the wood shavings also move up and down, and this up and down movement hits the waterproof paper, and the waterproof paper is made of wood. The corners of the slide may hit and be scratched. Rainwater may leak from here as well.

Fourth, depending on the type of roof tile, the tile may be nailed to the hook bar so that it does not slip off, but this nail may penetrate the hook bar and pop out, which may damage the waterproof paper.

The present invention was made in view of the above problems. In addition to not damaging the waterproof paper in the base structure of the tiled roof, rainwater is prevented from flowing into the nail holes formed on the waterproof paper by nailing. It is an object of the present invention to provide a base structure for a tiled roof, which can prevent rain leakage from the tiled roof, and a base structure having excellent wind and rain resistance.

In order to solve the above problems, the base structure of the tiled roof according to the present invention is
A plurality of field boards are pasted on the entire surface of the multiple rafters that form the base of the tiled roof, and waterproof paper is pasted on the entire surface of these field boards.
Multiple narrow slabs facing the roof flow direction on the waterproof paper are located on each rafter and attached at regular intervals via a narrow double-sided adhesive waterproof tape.
The main feature is that a hook bar for hanging roof tiles is attached by nailing on a plurality of thin plate members at regular intervals, which are composed of square timbers having a thickness of 25 to 40 mm and a width of 25 to 40 mm. It is desirable that the hook bar is made of square lumber having a thickness of 30 to 36 mm and a width of 30 to 36 mm.

The base structure of the tiled roof according to the present invention is
The second feature is that a double-sided adhesive waterproof tape having substantially the same width is attached to the entire surface of the lower surface of the thin plate material in advance.

The base structure of the tiled roof according to the present invention is
The third feature is that a plurality of narrow thin plates are located on each rafter and are attached to the waterproof paper at regular intervals via narrow double-sided adhesive waterproof tape. do.

The base structure of the tiled roof according to the present invention is
The fourth feature is that the upper waterproof paper is covered and pasted on the staples that fasten the lower waterproof paper to the field board.

The base structure of the tiled roof according to the present invention is
The narrow thin plate material is attached on the waterproof paper via the double-sided adhesive waterproof tape at the intermediate position of the plurality of narrow thin plate materials attached on each rafter, and at a position off the top of the rafters. The fifth feature is that the hook rails are attached to these thin plate materials by nailing.

As described above, according to the base structure of the tiled roof according to the present invention, narrow thin plate materials are attached to the waterproof paper via double-sided adhesive waterproof tape at regular intervals, and a conventional hooking bar is placed on the thin plate material. Since the hook rail with a larger cross-sectional area is attached, the probability that the nail that holds the roof tile will protrude below the hook rail is reduced, so that the waterproof paper will not be damaged by the nail, and the conventional hook It also eliminates the contact of the hooking bar with the waterproof paper caused by the crosspiece, and has the effect of preventing rain leakage from the roof base.

Further, the above structure has an effect that it is possible to realize a base structure of a tiled roof which is excellent in wind and rain resistance and has a high effect of preventing rain leakage even in a considerably strong wind and rain such as a typhoon.

Front view showing the condition, Explanatory drawing showing the action of the base structure of the tiled roof according to the present invention, It is a perspective view which shows the base structure of the tiled roof of another embodiment which concerns on this invention.

An embodiment for carrying out the present invention will be described with reference to the drawings. 1 to 7 show an embodiment of a tiled roof base structure according to the present invention, and in these figures, reference numeral 10 indicates a tiled roof.

In the tiled roof 10, as shown in FIG. 2, the purlin (haze) 12 is directly erected on the beam 11, or the purlin (tsuka) 13 is erected, and the purlin 12 and the purlin 14 are horizontally laid on the purlin (tsuka) 13. A plurality of rafters 15 are laid at regular intervals from the roof tile 14 to the purlin 12 on the eave side in the flow direction (inclination direction) of the roof. Square lumber is used for the purlin 12 and the rafters 15, and the purlin 12 closest to the eaves is called a nose purlin.

On the rafters 15, as shown in FIGS. 2 and 3, a plurality of field boards 16 are attached to the entire surface of the roof without gaps by nailing. As shown in FIGS. 2 and 4, waterproof paper (roofing) 17 is attached to the entire surface of the roof on the field board 16. As shown in FIG. 4, the waterproof paper 17 is partially overlapped and pasted so that the upper waterproof paper 17 is covered on the staples that fasten the lower waterproof paper 17 to the field board 16. ing.

As the waterproof paper 17, asphalt roofing in which asphalt is impregnated into a base material (paper, non-woven fabric, etc.) to improve waterproofness, or modified asphalt roofing in which rubber or plastic is mixed with asphalt to improve durability are used.

On the waterproof paper 17, as shown in FIGS. 2 and 5, a plurality of narrow wooden shavings 18 facing the flow direction of the roof are located on the respective rafters 15, and the narrow double-sided bonding is performed. It is attached at regular intervals via the waterproof tape 19. The wood shaving 18 is a thin plate material having a thickness of 12 m to 15 mm and a width of 6 cm, and is installed to create a gap S through which rainwater flows down between the waterproof paper 17 and the hooking rail 20 described later.

The double-sided adhesive waterproof tape 19 is made of an adhesive, adhesive and waterproof tape having a narrow width and a constant thickness, and is firmly adhered to the lower surface of the wood chip 18 in advance. The double-sided adhesive waterproof tape 19 is provided with rubber-based, acrylic-based, silicon-based adhesives, and adhesives having a constant thickness on both sides of a base material such as a non-woven fabric.

As shown in FIGS. 1 and 2, a plurality of hook rails 20 facing in the horizontal direction are attached to each of the timbers 18 by nailing at regular intervals. Each hook 20 uses a square lumber having a cross-sectional area larger than usual, and as shown in FIG. 2, the hook portion 21A provided on the upper part of the roof tile 21 is hooked. As the roof tile 21, in addition to clay roof tiles and ceramic roof tiles having excellent durability, heat insulation, fire resistance, waterproofness, and soundproofing, cement roof tiles, concrete roof tiles, and the like are used.

Next, the construction procedure for the base structure of the tiled roof configured as described above will be described below together with the operation.

First, with reference to FIG. 2, the beam 11 is laid over the existing pillar 1 and eaves girder 2. Next, the eaves-side nose purlin 12 is laid horizontally on the beam 11, and the middle purlin 12 and the central purlin 14 are laid horizontally on the bundle 13. Next, a plurality of rafters 15 are bridged in the flow direction of the roof (inclination direction of the roof) at regular intervals from the central ridge 14 to the nose purlin 12 on the eaves side. In the case of a tiled roof, the rafters 15 generally use square timbers having a width of 4.5 cm and a height of 6.0 cm, with an interval of 455 mm.

Next, on the rafters 15, as shown in FIG. 3, a plurality of field boards 16 are nailed to the entire surface of the roof. The field board 16 has a thickness of 12 mm to 15 mm. Next, as shown in FIG. 4, the waterproof paper 17 is attached to the entire surface of the roof with staples on the field board 16. The waterproof paper 17 is partially overlapped on the staples that stop the lower waterproof paper 17 so that the upper waterproof paper 17 covers the staples. This prevents rainwater flowing on the waterproof paper from leaking to the attic from the part where the staples are driven.

Next, as shown in FIG. 5, narrow wood chips 18 are nailed on the waterproof paper 17 at regular intervals so as to face the flow direction of the roof according to the positions of the rafters 15. .. A double-sided adhesive waterproof tape 19 is attached to the lower surface of the wood chip 18 in advance. The double-sided adhesive waterproof tape 19 is used by peeling off the release paper on the adhesive surface when attaching. The wood shaving 18 uses a plate material having a thickness of 7 mm to 9 mm and a width of 4.5 cm. The double-sided adhesive waterproof tape 19 has a width and length substantially the same as that of the wood chip 18.

When the wood shavings 18 and the double-sided adhesive waterproof tape 19 are nailed onto the waterproof paper 17 at regular intervals, a guide guide for rainwater to flow down on the waterproof paper 17 is formed. Rainwater that has entered under the roof tiles stops at the double-sided adhesive waterproof tape 19 of the guide guide, and does not flow or soak under the wood shavings 18, and rainwater leaks from the nail holes made by nailing the wood shavings 18. There will be no such thing.

Next, as shown in FIG. 1, a plurality of hook rails 20 are horizontally hung on the wood shavings 18 and nailed on the wood shavings 18 at regular intervals. The hook 20 uses a square lumber having a cross-sectional area (thickness 30 to 36 mm, width 30 to 36 mm) larger than the normal size (thickness 15 mm, width 18 to 30 mm). By using a size larger than usual for the hook rail 20, the tile does not bend or bend due to the weight of the tile, and the tile does not move easily. Further, even if a considerably strong wind such as a typhoon blows, the tiles do not move so much, the hooking rail 20 does not hit the waterproof paper 17 as in the conventional case, and the waterproof paper 17 is not scratched.

Finally, the roof tiles 21 are sequentially hooked and nailed to each hook rail 20 to be attached.

According to the base structure of the tiled roof of the present embodiment, the following effects are obtained.

Since the wood shaving 18 with the double-sided adhesive waterproof tape member 19 attached to the lower surface is nailed onto the waterproof paper 17 to stop it, rainwater that has entered under the tile 21 can be collected at the double-sided adhesive waterproof tape 19 of the guide guide. It stops and does not flow under the wood chip 18, but is discharged to the outside on the waterproof paper 17. Since rainwater does not flow under the wood shaving 18 and does not soak into the wood shavings 18, rain does not leak from the nail holes made by nailing to stop the wood shavings 18.

Since a square lumber having a cross-sectional area larger than usual is used for the hook rail 20, the hook rail 20 does not bend or bend due to the weight of the roof tile 21. As a result, the tile 21 does not move easily, and the tile 21 does not move so much even when a fairly strong wind blows. Further, the hook 20 does not hit the waterproof paper 17 or the waterproof paper 17 is not scratched, and the waterproof paper 17 is not damaged and leaks. As a result, a base structure having excellent wind resistance and water resistance can be obtained.

If there is a risk that the hooking rail 20 will bend due to the use of a heavy roof tile (for example, a thick cement-based roof tile) for the roof tile 21, as shown in FIG. , The reinforcing wood shaving 18'may be arranged by the double-sided adhesive waterproof tape 19'at a position off the top of the rafter 15. Reinforcing wood chips 18'may be arranged at regular intervals. A heavy roof tile (for example, thickness) is attached to the roof tile 21 by arranging a reinforcing tree 18'between the tree 18 and the tree 18 on the rafter 15 and nailing the hook 20 to the tree 18'. Even when using a type of cement-based roof tile), it is possible to prevent the hook rail 20 from bending or bending, which also prevents the waterproof paper 17 from being damaged and leaking rain, and is wind resistant and water resistant. An excellent base structure can be obtained.

Since the upper waterproof paper 17 covers the staples that fasten the lower waterproof paper 17 to the field board 16, rainwater flowing on the waterproof paper 17 is prevented from leaking to the ceiling from the portion where the staples are driven.

It is sufficient to attach double-sided adhesive waterproof tapes 19 and 19'on the lower surface of the wood chips 18 and 18'and prepare the required number of wood chips 18 and 18'to be attached to the entire roof surface in advance, so that the work can be carried out at a relatively low cost and with high work efficiency.

Thus, according to the base structure of the tiled roof of the present invention, it has become possible to provide the base structure of the tiled roof having excellent wind resistance and water resistance, that is, wind and rain resistance, at a low cost.

The tiled roof base structure according to the present invention can prevent rain leakage and can be widely used as a tiled roof base structure having excellent wind and rain resistance.
