BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to the structure of tiled roofs.

0002

[Prior Art] A typical conventional tiled roof structure involves laying waterproof paper on the sheathing board of the roof, and attaching the tiles to tile beams that are fixed to the sheathing board by nailing. It is being installed.

0003

[Problems to be Solved by the Invention] In the above-mentioned tiled roof structure, as a means for fixing the tiles to the tile beams of the shedding board 106, as shown in FIG.
Place the tile in the suspended state and attach it with nails or screws 103.
01 into the tile beam 101, or
As shown in 5, a method is used in which a fastening wire 104 passed through a tile 102 is nailed to a roofing board 106 using a dowel nail 105, thereby fixing the tile 102.

However, in the above-mentioned roof structure, holes are made in the waterproof paper laid on the roofing board 106 by the nails or screws 103, 105 for fixing the tiles 102. Therefore, under conditions of strong wind and rain such as a typhoon,
Rainwater that has entered through the gaps between tiles may also enter the roof sheathing board 106 through the above-mentioned nail holes, causing rain leaks.

[0005] Therefore, in order to prevent rainwater from entering the roof board 106, a thick and sticky rubber or asphalt waterproof sheet is sometimes used as an underlayment material, but these are expensive and They are difficult to handle, and once a leak occurs, it is difficult to pinpoint the location of the leak, often requiring complete repairs.

[0006] In order to eliminate the above-mentioned rain leakage, it is most important to carefully mark the tiles and arrange them with precision so that the tiles are tightly laid and there are no gaps between the tiles. However, as mentioned above, hard roof tiles require the skills of skilled workers, and the number of skilled workers is decreasing at present.

[0007] An object of the present invention is to improve the waterproofness and workability of a tiled roof structure by providing a waterproofing means that is easy to construct and has reliable waterproofness in addition to the waterproofing caused by the tile roofing. be.

[0008]

[Means for Solving the Problems] In order to solve the above problems, the present invention takes the following measures. The tiled roof structure of the present invention is a tiled roof structure in which a sub-roofing material made of metal plates is laid horizontally on the base of the roof, and tiles are laid on top of the sub-roofing material, wherein each of the above-mentioned sub-roofing materials An engaging part that engages with each other is formed along both the upper and lower edges of the roofing material, and a crosspiece is integrally formed upright along the lower edge of the underlayment material, and a functional hole is formed that connects the crosspiece vertically. are provided at intervals along the rising part of the crosspiece.

[0009] A receiving part for supporting the tile on the surface may be formed on the crosspiece of the above-mentioned under-roofing material. Moreover, it is preferable that the function hole be a long hole that is long in the direction of the slope of the roof. A concave gap may be formed along the joint between the lower edge and the upper edge surface of the underlayment materials.

0010

[Operation] According to the above means, the under-roofing material made of metal plates is laid horizontally on the base, and the engaging parts formed on both the upper and lower edges engage with each other, so that the upper roof Adjacent underlayment materials are joined to each other in the lower tier. The under-roofing material provides the same level of waterproofing as a metal sheet roof structure on the inside of the tiled roof.

A crosspiece is integrally formed along the lower edge of each under-roofing material, and when roofing with tiles, each tile is placed and fixed with reference to the crosspiece. The functional hole that communicates the top and bottom of the crosspiece serves as a through hole for the tie wire that fixes the tile, and at the same time,
It also serves as a hole for draining rainwater on the underlayment. Rainwater that enters through gaps between tiles due to strong winds and rain passes through functional holes provided in the rising parts of the crosspieces of each underlayment, and then flows down to the eaves and is drained.

[0012] Furthermore, by forming a receiving part on the crosspiece of the under-roofing material to support the tile with a surface, it becomes possible to use that surface to drive nails or screws to fix the tile. By forming the above-mentioned functional holes into elongated holes that are long in the direction of inclination of the roof, the surface tension that occurs when rainwater passes through the functional holes is reduced, and the drainage capacity of the holes is improved.

Furthermore, if a concave gap is formed along the joint between the lower edge and the upper edge surface of the base roofing materials, a sufficient space will be formed between the members at the joint, which will prevent rainwater from accumulating. This prevents the capillary phenomenon that causes pores from occurring, allowing rainwater from the functional holes to smoothly flow down from the joint.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show a tiled roof structure in which the present invention is implemented. The illustrated roof is that of a wooden house, with rafters a2 placed at regular intervals on top of the main building a1, and a base layer a3 pasted on top of the rafters a2. The base a3 described above is constructed by pasting a base sheet 3b such as asphalt roofing on the surface of plywood 3a. Incidentally, as the base material, an ALC panel, a concrete frame, etc. may be used in some cases.

[0015] Then, an under-roofing material 2 made of a metal plate is laid horizontally on the base a3, and a cross-piece tile 1 is further laid on this under-roofing material 2. As shown in FIG. 4, the underlayment material 2 is made of a fixed length or long strip-shaped metal plate, and is formed by roll forming and bender forming to form engaging portions that engage with each other along both upper and lower edges. 4a and 4b are bent and formed, and a crosspiece 5 is formed to stand up parallel to the engaging portion 4b on the lower edge side. The crosspiece 5 is for placing and fixing the crosspiece tile 1, and as shown in FIG. 1, the lower edge of the underlayment material 2 is folded multiple times toward the upper surface side, so that it stands in an inverted L-shape in cross section. It is raised and formed.

The lower edge of the underlayment material 2 extending from the above-mentioned crosspiece 5 is folded back to the lower surface side to protrude toward the ridge side, and its tip is folded back again to form the engaging portion 4b. Therefore, the above-mentioned crosspiece 5 is formed upright along the lowermost end of the under-roofing material 2, and the engaging portion 4b on the lower edge side is parallel to a position along the back side of the above-mentioned crosspiece 5, somewhat inward. It will be formed as follows.

[0017] Furthermore, the upper edge side engaging portion 4a is formed by bending the upper edge of the underlayment material 2 multiple times toward the upper surface side.
It is formed into a substantially hook-shaped cross section that opens toward the eave side, and furthermore, a fixing piece 6 for nailing a nail 7 is formed with its tip extending toward the ridge side. As shown in the enlarged view of FIG.
The other engaging portion 4b is engaged by being inserted into the opening groove.

Normally, as shown in FIG. 4, the under-roofing material 2 is laid horizontally on the upper surface of the roof base a3 in parallel with the main building a1 from the eaves side to the ridge side. By fixing the fixing piece 6 on the upper edge of the under-roofing material 2 to the base a3 by driving 7 nails, and engaging the engaging portions 4a and 4b of the adjacent under-roofing materials 2 in the upper and lower tiers. , the vertically adjacent undercoating materials 2 are joined together.

In these joint parts, the engaging part 4b is inserted into the mating engaging part 4a, and the engaging part 4a and the fixing piece 6 of the lower sheathing material 2 are inserted into the mating part 4a by the upper sheathing material 2. Being covered ensures waterproofness against rainwater. still,
Although the fixing piece 6 for fixing is integrally formed on the upper edge of the base roofing material 2 described above, the upper edge of the base roofing material 2 may be fixed to the base a3 via a hanger.

[0020] In addition, when using the fixed-sized under-roofing material 2, the connection at both the left and right ends is performed by applying a waste board to the back of the connection part, but a water-stopping cushion made of resin or rubber is placed in the middle of the connection part. By interposing 10, waterproofness can be improved.

[0021] As described above, once the under-roofing material 2 made of metal plates is covered, this roof structure has waterproofness equivalent to that of a conventional roof structure made of metal plates. At the same time, the crosspiece 5 formed integrally with the under-roofing material 2
project in parallel to each other along the joints of the under-roofing materials 2, and serve as a reference when roofing with tiles while maintaining accurate positional relationships.

By the way, the under-roofing material 2 is generally installed from bottom to top from the eaves to the ridge of the roof, but in the embodiment shown in FIGS. 9 and 11, the under-roofing material 2 It is also possible to use the method of roofing 2 from top to bottom, from the ridge to the eaves. This construction method eliminates the need for large-scale scaffolding, and also prevents many problems such as preventing damage to the installed underlayment material 2 by stepping on it, and preventing rainwater from penetrating into the processed parts even if it rains during construction. This has advantages, especially when the slope of the roof is steep.

[0023] In the rising part of the crosspiece 5 in the above-mentioned undercoating material 2, there are two functional holes 8a, which communicate the crosspiece 5 vertically.
8b has been opened. The functional holes 8a and 8b have the function of allowing rainwater that has entered through the gaps in the tiles 1 to pass through and flow toward the eaves, as will be described later, and the function of tightening the tiles 1 through the tightening wires 9 that fix them.

[0024] The crosspiece tiles 1 to be laid on the under-roofing material 2 are successively laid from the eave side of the roof toward the ridge, with the upper edge crosspiece portion 1a being hooked to the crosspiece portion 5 of the under-roofing material 2. As shown in the enlarged view of FIG. 1, the crosspiece tile 1 placed on the crosspiece 5
The fastening wire 9 passed through the fixing hole 1b of the roof tile 1 is further passed through both functional holes 4a, 4b of the crosspiece 5 and fixed to the crosspiece 5 by tightening it in an annular shape.

As mentioned above, the crosspiece 5 protruding from the underlayment surface
They are arranged parallel to each other while maintaining an accurate positional relationship at the time when the base roofing material 2 is installed. Therefore, the work of allocating and attaching tile beams, which was conventionally done, is no longer necessary, and by laying the tile tiles 1 based on the precisely placed beams 5, the work does not require particularly advanced technology. Even a person can install tiles accurately.

[0026] The tiled roof structure constructed as above is as follows:
It has a dual structure consisting of an under-roof made of metal plates and a tile roof, and according to this structure, it has a waterproof function due to both the tile roof and the under-roof. Both function holes 4a and 4b are provided with fastening wires 9 for fixing the crosspiece tile 1 in the crosspiece 5 of the underlayment material 2.
Since it is constructed so that it can be tightened using the roof structure, there are no nail holes penetrating the underlayment material 2 within the range where rainwater can infiltrate in the roof structure, thereby ensuring reliable waterproofness. Can be done.

Furthermore, even if rainwater enters through gaps in the tile roofing due to strong winds and rain, the rainwater will flow through the crosspieces 5 of the under-roofing material 2.
Since the water flows down the under-roofing to the eaves while passing through functional holes 4a and 4b opened in the roof and is quickly drained, the problem of rainwater remaining indefinitely between the under-roofing and the tile roofing can be solved.

The base roofing material 2' shown in FIG. 5 has a functional hole formed in the rising part of the crosspiece 5 in the shape of a long hole extending in the direction of the inclination of the roof. In this way, both function holes 4a', 4
By opening b' in the shape of a long hole, rainwater that has entered the interior of the tiled roof can flow through the function holes 4a' and 4b' as described above.
It is possible to reduce the surface tension that occurs when trying to pass through. As a result, the functional holes 4a', 4b'
In addition to being able to improve the drainage capacity of the structure, it is also possible to improve the workability when passing the tie wires 9 of the tile beams 1 through.

FIGS. 6 to 15 show examples of underlaying forms, and these examples will be explained below in order. In FIGS. 6 and 7, receiving parts 25a and 35a are formed on the tops of the crosspieces 25 and 35 of the under-roofing material 2 to support the crosspiece tiles 1 on their surfaces,
In the case of FIG. 6, the crosspiece 25 is formed into a substantially U-shape, and in the case of FIG. 7, the crosspiece 35 is formed into a substantially rectangular shape, thereby forming planar receiving portions 25a and 35a, respectively. Like this,
A receiving part 25 that receives the crosspiece tile 1 on the upper surface of the crosspieces 25 and 35.
, 35, the crosspiece tile 1 can be fixed not only by the above-mentioned fastening wire 9 but also by nails or screws 7. Further, if necessary, it is also possible to use the fastening wire 9 and nails together. In the above-described embodiment, the function holes 8a and 8b are opened so as to protrude toward the lower surface.

FIG. 8 shows that, contrary to the above-mentioned embodiment, the crosspiece 4
5 is raised up into a plate shape, and supports the crosspiece 1 at its upper edge. In FIG. 9, the crosspiece 55 is formed to stand up like the crosspiece 45 of the above embodiment, but the crosspiece 55
It is formed by folding a fixing piece 56 extending from the engaging portion 54b on the back side toward the eaves.

In the embodiment shown in FIG. 10, an engaging portion 64a on the upper edge side of the under-roofing material 2 is bent into a hook shape that opens toward the eaves, and the upper-stage under-roofing material 2 is inserted into this engaging portion 64a. The tip of the lower edge side engaging portion 64b is inserted and engaged. and,
The tip edge of a hanger piece 66 formed separately from the underlayment material 2 is hooked and engaged with the tip of the engaging portion 64a, and the rear end side of the hanger piece 66 is nailed to the base a3. It is stopped at 7.

In the embodiment shown in FIG. 11, the proximal edge of the hanger piece 76 is bent into a hook shape that opens toward the eaves, and engaging portions 74a and 74b are formed in the opening of the hanger piece 76. The tips of the hanger pieces 76 are folded back toward the eaves and fixed with nails 7.

In the embodiment shown in FIGS. 12 and 13, concave gaps 11 and 12 are formed along the joint between the lower edge and the upper edge surface of the base roofing materials 2. Figure 12
In this case, the above-mentioned gap 11 is formed over the entire length of the joint between the underlaying materials 2 by providing an upward step in front of the engaging portion 84b on the lower edge side formed by folding back from the crosspiece 85 to the back side. In addition, in the case of FIG. 13, the gap 12 is similarly formed by forming a downward step along the portion of the upper edge surface that contacts the crosspiece 95.

In both of the embodiments described above, the gaps 11 and 12 described above are formed along the joint between the lower edge and the upper edge of the base roofing material 2, and the lower side is formed in this gap space. A functional hole 8b is visible.

For example, if the joint between the lower edge and the upper edge surface of the underlayment material 2 is joined with almost no gap as shown in the embodiments up to FIG. There is a possibility that rainwater that flows down through the function holes 8a and 8b will accumulate due to the capillary phenomenon that occurs.

Therefore, as described above, by forming the concave gaps 11 and 12 along the problematic joint, capillary phenomenon at the same location can be effectively prevented, and rainwater flowing down from the functional hole 8b can be prevented. This allows rainwater to flow down smoothly and prevent rainwater from accumulating in the joints.

Although each of the above embodiments shows a tiled roof structure compatible with a wooden roof base, the tiled roof structure of the present invention can also be implemented on a steel frame roof base. Furthermore, the same method can be applied not only to Japanese tiles but also to Western tiles such as Spanish tiles.

[0038]

[Effects of the Invention] Since the present invention is constructed as described above, it produces the following effects. It has a double structure consisting of an under-roofing made of metal plates and a tiled roof, and is configured so that it can be tied together with a tie wire that fixes the tiles using functional holes in the crosspieces of the under-roofing material. Within the range where rainwater can infiltrate, nail holes that cause rain to leak from the underlayment material, which serves as the waterproof layer of the underlayment material, can be completely eliminated, thereby ensuring reliable waterproofness.

Since the crosspiece is integrally formed along the lower edge of the under-roofing material, the installation of the tile crosspiece, which determines the accuracy of tile roofing, can be done accurately at the same time as under-roofing. In addition to eliminating the need for marking and attaching the crosspieces, it is possible to perform accurate and beautiful tile roofing using the crosspieces as a reference even if the worker does not have particularly advanced skills. Furthermore, even if rainwater enters the inside of the tile roof due to strong winds and rain, it will quickly drain away by passing through the functional holes made in the crosspieces of the underlayment and flowing down over the underlayment to the eaves. It also prevents rainwater from lingering between the roof and the roofing.

[0040] By forming the receiving part for receiving the tile on the surface of the above-mentioned crosspiece of the under-roofing material, the tile can be fixed using any method of fastening wire, nails, or screws (or both methods). But it can be fixed.

[0041] Furthermore, by making the functional hole opened in the rising part of the crosspiece into a long hole, the surface tension generated when rainwater passes through the functional hole is reduced, and the drainage capacity of the hole is improved. Workability when tying the tying wire can also be improved.

Furthermore, by forming a concave gap along the joint between the lower edge and the upper edge surface of the underlaying materials, the capillary phenomenon that occurs at the joint can be prevented, and the functional pores can be closed. This allows rainwater to flow smoothly down from the joint and prevents rainwater from accumulating within the joint.
