Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roofing material used for buildings such as houses, and more particularly to a roofing material fixed to a roof surface with nails or the like.

[0002]

2. Description of the Related Art In many cases, roofs of houses and the like have corner ridges and valleys, and it is necessary to cut roof materials into appropriate shapes and dimensions in these portions. The cut roof material is fixed using nails or an adhesive. Generally, nailing of the roofing material is performed at the overlapping part of the buttocks. Since this part is covered by the upper roofing material, the nail hole is not exposed, and it is a safe place in the rain. Fixing with an adhesive is not only easily affected by construction conditions,
In particular, in the case of three-dimensional roofing materials, there is little contact between the roofing material and the ground board, or between the roofing materials, so often the bonding area cannot be sufficiently obtained, and there is a possibility that the fixing force may decrease due to deterioration, If possible, nailing is more secure. However, in the case of a cut material that does not include the buttocks, it is unavoidable to fix it with an adhesive or to perform a sealing process after nailing the exposed working surface. The nailing of the exposed working surface is not preferred in terms of the rain, even though it is subjected to a sealing treatment. From the viewpoint of fixing the roofing material, the part using the cut roofing material was a weak point.

[0003]

SUMMARY OF THE INVENTION According to the present invention, in the construction of a roofing material, even if the roofing material is cut, a fixed portion at the buttocks always remains, and all the roofing materials can be fixed by a fixing tool on an unexposed surface. An object of the present invention is to provide a possible roofing material and a construction method thereof.

[0004]

Means for Solving the Problems The inventors of the present invention have proposed a high-efficiency ceramic roofing material in which the overlap margin has been reduced by installing a water channel portion and a water return, with respect to the length in the flow direction (vertical). The present inventors have found that the above-mentioned problems can be solved by increasing the length (working width) in the direction perpendicular to the flow, and have reached the invention. That is, the present invention provides (1) a three-dimensional ceramic roofing material having a water channel portion in a flow direction and a fixing portion at a butt portion, wherein the working width of the roofing material is 2 to the length in the flow direction. (2) In the method for constructing a ceramic roofing material according to (1), wherein the ceramic roofing material is arranged in a row on the ground, The roofing system according to claim 1, wherein the roofing material located at the end having an angle with respect to the flow direction is cut in accordance with the shape of the end except for the fixing part of the buttocks, and fixed with a fixing tool. Material construction method.

[0005] The ceramic roofing material of the present invention, by simple adjustment at the time of construction, the bottom part is always left in the cut roofing material, it is possible to fix it at this location with a fixture, without lowering the rain-closing performance, The roof can be made strong against various external forces such as earthquakes and winds. In the present invention, the ceramic roofing material is composed of so-called ceramic materials that are conventionally used as roofing materials, such as ceramic tiles, clay tiles, concrete tiles, decorative asbestos slate, asbestos-free decorative slate, and fiber-reinforced cement boards. Roofing material. A nail is usually used as the fixing tool, but another fixing tool such as a screw may be used depending on the configuration of the field.

Hereinafter, the present invention will be described in detail. In the case of a roofing material that is flat and does not overlap with adjacent roofing materials (there is no water channel part) like a general makeup slate, a large amount of overlap in the flow direction is required, and To prevent this, the gaps between adjacent roofing materials must not be aligned in the flow direction, and are usually installed in a staggered manner.

However, in the case of a three-dimensional ceramic roofing material having a water channel portion, water entering through a gap between adjacent roofing materials is discharged through the water channel portion. Even so, waterproof performance is exhibited. Therefore, the position of the roofing material in each step is not particularly limited in terms of the lateral position for reasons of waterproofing.
Construction in a row or in a zigzag is a requirement from the roofing material shape and design.

A typical example of a three-dimensional roof material having a water channel portion according to the present invention is shown in FIGS. 1 and 2, and the names of parts used in this specification are described. FIG. 3 shows a schematic sectional view at the time of construction. As shown in the figure, since there is a water return on the buttocks and the water channel,
The overlap margin is small, and the fixed part is covered with the upper roofing material, so that excellent waterproof performance can be exhibited. Usually, the fixing portion is provided with a fixing nail hole, and this portion is fixed with a nail. However, it is also possible to newly provide a hole in the fixing portion and fix the nail at the time of construction. The cutting of the roofing material, which usually takes place on the roof of a residential roof, is parallel to the flow direction in the plan view of the roofing material.
The angle is 45 degrees. The actual cutting angle is slightly smaller due to the roof slope, so that even when cutting at 45 degrees, the fixing portion can be reliably secured if the buttocks remain, and nails can be fixed.

The three-dimensional roof material according to the present invention does not need to be installed in a zigzag manner, and even if the installation position is adjusted to the left and right, it does not cause a problem in the rain. Therefore, when the roof material is fixed to the roof ground surface. The roofing materials may be arranged for each step, and the roofing materials at both ends may be adjusted by adjusting the left and right positions so that the fixed portions remain. However, by adjusting the construction position,
In order to secure a fixed portion that can be nailed at any step width, a working width (width) that is at least twice as long as the length in the flow direction (vertical) is required. When the roofing material is constructed on one side of the ridge roof, as shown in FIG. 4, the roofing material at both ends is cut at an angle of about 45 degrees, and such a case will be described below as an example.

FIGS. 5 and 6 show the maximum width that can be constructed with three roofing materials and the minimum width that can be constructed with four roofing materials. The term “workable” as used herein means that work can be performed to fix the buttocks with a fixing tool even with a cut roof material.
FIG. 5 shows a conventional roofing material whose working width is less than twice the length in the flow direction. FIG. 6 shows a roofing material according to the invention whose working width is more than twice the length in the machine direction. The minimum width that can be applied is determined as the width necessary to leave the fixed part of the buttocks. If it is cut shorter than this, the buttocks are cut off, and the fixed portion cannot be secured. In the case of the conventional roofing material as shown in FIG. 5, (maximum width that can be constructed with three sheets) <(minimum width that can be constructed with four sheets). Insufficiently, the fixed part of the cut roof material cannot be secured with four sheets. In general, (maximum width that can be constructed with n sheets) <(minimum width that can be constructed with (n + 1) sheets). It can no longer be secured.

However, if the working width of the present invention is 2 to 5 times the length in the flow direction as shown in FIG. 6, (the maximum width that can be constructed with three sheets) ≧ (4) What is the size of the step, since (the minimum width that can be constructed with n sheets) ≧ (the minimum width that can be constructed with (n + 1) sheets)? Even with respect to the width, it is possible to perform the work of fixing the cut roof material on both sides with a fixing tool on the non-exposed surface. That is, by using a horizontally long roof material having a working width of 2 to 5 times the length in the flow direction according to the present invention, by adjusting the horizontal position of the roof material in the construction of each step,
Even with the cut roof material, the roof surface fixed with the fixture can be constituted by the non-exposed surface (FIG. 7).

As described above, if the working width of the three-dimensional roofing material having the draining portion is at least twice the length in the flow direction, all the cut roofing materials are also fixed by position adjustment during construction. Although it is possible to fix with a tool, if it is made extremely long horizontally, the weight per sheet becomes heavy, transportation and handling become difficult, and the workability deteriorates. Therefore,
The working width is preferably not more than 5 times the length in the flow direction. If it is necessary to arrange them regularly, such as in a staggered design, the mounting position will be restricted by the relationship with the adjacent steps. In addition, it is possible to fix all the fixing materials of the roofing material. It has a design surface divided into three equal parts,
The following describes a case in which a staggered construction is performed with one roof material having an appearance as if three roof materials are constructed.

[0013] Roofing material whose working width is three times the length in the flow direction,
When installing on a triangular roof surface (an example of a ridge roof)
When the construction is performed as shown in FIG. 10, small cut pieces are required in the first and fifth steps, and a roof material that cannot be fixed with nails is generated. However, since the working width of the roofing material is long, the cutting position is shifted at the beginning of the application, and as shown in FIG.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples and comparative examples of the present invention will be described below, and will be described in more detail.

[0015]

[Embodiment 1] FIGS. 8 and 9 are schematic views showing the layout of tiles in the case of performing construction on one side (triangle) of a ridge-like shape with a roof material whose working width is twice the length in the flow direction. Shown in In the case of staggered construction, as shown in Fig. 8, a cut roof tile that does not leave the bottom of the tile and cannot be fixed with a nail on the non-exposed surface occurs,
As shown in FIG. 9, by shifting the roofing material in the horizontal direction, the tile bottom remains in all the cut tiles,
The nail can be fixed on the non-exposed surface.

[0016]

Comparative Example 1 FIG. 12 is a schematic diagram showing a case where a roof similar to that of the embodiment is staggered with a roof material having a working width of less than twice the length in the flow direction. Many cutting materials that cannot be fixed with nails are generated. Therefore, even if the position in the horizontal direction is adjusted so that the tile bottom remains in the cutting member, as shown in FIG. 13, the cutting material that does not include the tile bottom remains, and the non-exposed surface of these cut materials remains. It becomes impossible to fix the nail.

[0017]

By using the roofing material of the present invention, not only the fixing of the roofing material at the beginning of the roofing but also the roofing material at the end of the roofing can be fixedly fixed by the fixing portion at the buttocks. Thus, a roof surface having excellent fixing strength can be formed.
Since the fixed portion is covered by the upper roof material, no problem occurs in the rain. In addition, since all the roof materials at the corners and valleys can be fixed to the fixtures, a very strong roof surface can be constructed, and it is possible to exert a great effect in preventing the roof materials from scattering and shifting due to an earthquake or wind. .
