Abstract

PURPOSE: To reduce cost on the execution of works by setting the width of each roof panel at positive integer tomes to the module width of a constant length together with the reference width of a roof surface, in which these roof panels are joined mutually and formed in one surface, and the width of a roofing tile. CONSTITUTION: In a hip roof 1, the centers 13 of columns disposed at the corner sections of a building are placed just under inclined ridges 3, the reference width L of roof surfaces 4A, 4B is set as a distance between the centers 13, and the reference width L is set at positive integral times to the module width (a) of constant length together with the width Wi of each roof panel 6 and the width D of roofing tiles. D=a×1 (L), Wi=axmi and L=a×n hold. (where the relationship of positive integer times satisfying 1<mi<n holds in 1, ml and (n)). When reference width L is changed, the hip roof 1 can cope only with the roofing panels 6 having the mounting pattern of preset roofing tiles 5 by altering the width of the adjusting panels of W3 at every module width (a), thus reducing cost on the execution of works.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof panel and a roof of a building using the roof panel.

[0002]

2. Description of the Related Art For example, in the construction of a roof of a building such as a house, in view of the recent shortage of workers and the soaring construction cost,
Unitized roof panels, which have been pre-roofed in roof tiles at factories, are used. This roof panel is lifted up by a crane or the like at a construction site and assembled to a shed assembly of a building, and a plurality of roof panels are joined flush with each other on the shed assembly to construct a roof surface with a constant slope. In this case, although the joining work of each roof panel remains as the on-site work, it is not necessary to perform the roofing work on most of the roof surfaces, and labor saving of the on-site work can be achieved (Japanese Patent Laid-Open No. 5-295832). (See the official gazette).

In the panel construction method using such a unitized roof panel, aesthetic treatment is performed so that the joint portion of the roof panel cannot be identified from the outside, and
In order to improve the waterproof property at that portion, the roof panels may be joined so that the roof tile roofing pattern on one roof surface is continuous. The roof panel in this case is
The roof tiles are roofed by shifting the width-wise pitches of the odd and even rows so that the joints that do not have roof tiles are left at the widthwise ends of the upper surface. By inserting a joining piece formed by cutting the roof tile into an appropriate width direction, the roof tile is constructed so that the roofing pattern of the roof tile is continuous (for example, JP-A-3- 84152).

[0004]

As described above, when joining roof panels so that the roof tiles have a continuous roofing pattern, for example, if the width of the roof panels is set to an integral multiple of the width of the roof tiles. The installation pattern of roof tiles on each roof panel can be made uniform. On the other hand, in residential construction, the shape of the building differs depending on the construction target,
Usually, the standard width of the roof surface changes. in this case,
Most of the roof panels do not match the standard width of the roof surface just by arranging only the roof panels (basic panels) of a certain width with a fixed roof tile installation pattern. A small roof panel (adjustment panel) is placed.

If an adjustment panel for adjusting the width is provided at the widthwise end of the roof surface, the roof surface may not be properly supported when the width of the panel reaches the eaves dimension. May have to be placed in the middle of the width direction of. In such a case, conventionally, the roof tile installation pattern for the roof panel has been determined by considering only the width dimension relationship with the roof tile, so that the width of the roof tile does not change with respect to the change in the reference width of the roof surface. When the width of the adjustment panel arranged midway in the direction is changed to cope with this, the installation pattern of the roof tiles of the adjustment panel is also changed correspondingly.

In this way, when the installation pattern of the roof tiles of the adjustment panel changes with the change in the reference width of the roof surface, when the adjustment panel is arranged in the widthwise middle portion of the roof surface, the adjustment panel is arranged. Since the joint patterns at both ends in the width direction of the adjustment panel are different between the left and right sides, the installation pattern of the basic panel joined to the adjustment panel must be different between the left and right sides of the adjustment panel.

For this reason, conventionally, the installation pattern of the roof tiles of the basic panel also has to be redesigned for each construction target in accordance with the change in the reference width of the roof surface, resulting in a high design cost. In addition, if the installation patterns of roof tiles on the basic panels placed on both sides of the adjustment panel are different, the types of joint pieces (joint pattern) required for joining work will increase,
Joining work on site becomes more complicated.

In view of such a situation, the present invention is directed to a change in the reference width of the roof surface even when the adjustment panel for setting the roof surface to the reference width is arranged midway in the width direction of the roof surface. The purpose is to reduce the design and construction costs by making it possible to deal with only the roof panel of the roof tile installation pattern set in advance.

[0009]

In order to achieve the above object,
The present invention has taken the following technical means. That is, the present invention is a roof panel in which the roof tiles are roofed by shifting the width-direction pitch between the odd-numbered rows and the even-numbered rows so as to leave a joint where the roof tiles are not roofed at the ends in the width direction. , So that the roofing pattern is continuous with other roof panels that are joined to each other, in a roof panel in which a joining piece formed by cutting the roof tile into an appropriate width direction is inserted into the joining portion, The width of each roof panel, together with the reference width of the roof surface and the width of the roof tiles formed by joining them together to be flush with each other, is a positive integer multiple or almost integer multiple with respect to the module width of a certain length. It is set (claim 1).

In this case, the roof panel has joints formed at both ends in the width direction, and the roof tile installation pattern is set so that the joint patterns of the joint pieces are the same for both joints. It is desirable (claim 2). Further, the present invention comprises a roof panel in which the roof tiles are roofed by shifting the width-direction pitch between the odd-numbered rows and the even-numbered rows so that a joint portion not roofing the roof tiles is left at the end in the width direction. , The roof surface is formed to be flush with each other by joining the roof panels to each other at their joints, and the roof tiles are arranged in an appropriate width direction so that the roofing pattern between the roof panels joined to each other is continuous. In a roof of a building in which a joining piece cut into a length is inserted into the joining portion, the reference width of the roof surface is a module width of a constant length together with the width of each roof panel and the width of the roof tile. Is set to a positive integer multiple or almost integer multiple (Claim 3).

In this case, a plurality of basic panels having the same width,
A roof surface having a reference width L is configured by joining together an adjustment panel having a width smaller than the basic panel,
It is preferable to dispose the adjustment panel in the middle of the roof surface in the width direction and at a position biased to one end side in the same direction (claim 4).

[0012]

In the present invention, not only the width Wi of each roof panel and the width D of the roof tile but also the reference width L of the roof surfaces 4A and 4B is set to a positive integer multiple with respect to the module width a of a constant length. Therefore, as the reference width L changes, the roof surfaces 4A, 4
Even if the width of the roof panel 6 arranged in the middle of the width direction of B is changed by the module width a, for example, as shown in FIGS.
The installation pattern of the roof tiles 5 can be set so as to be J4, and it becomes unnecessary to fundamentally change the installation pattern of the roof panel 6 with respect to the change of the reference width L (claims 1 and 3).

That is, if the reference width L of the roof surfaces 4A and 4B is changed in units of the module width a together with the width Wi of the roof panel, a preset installation pattern of the roof tile 5 instead of the basic panel 6A is set. By adopting the adjusting panel 6B that is provided, it is possible to cope with the change in the reference width L. Further, in the roof panel 6 in which the joints 10 are formed at both ends in the width direction, when the installation pattern of the roof tiles 5 is set so that the joint pattern Ji by the joint pieces 11 is the same for both joints 10 ( For example, referring to FIGS. 4 and 6, by continuously using the roof panel 6A having the pattern, the type of the joining piece 11 to be used can be the same for all the joints 10 related to the roof panel 6A (see FIG. 4 and FIG. 6). Claim 2).

Further, a plurality of basic panels 6A having the same width W1
And widths W2, W3, W4 smaller than the basic panel 6A
When the roof surfaces 4A and 4B having the reference width L are formed by joining the adjustment panels 6B and the adjustment panels 6B to each other, the adjustment panel 6B is biased toward the one end in the width direction midway of the roof surfaces 4A and 4B. If the roof tiles 5 are arranged in the same position, for example, as shown in FIG. 1 and FIG.
Only the basic panel 6A having the installation pattern can be used as much as possible on one roof surface 4A, 4B (claim 4).

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an exploded view of a roof 1 of a building in which the present invention is employed. This roof 1 is a so-called ridged roof,
It is provided with a trapezoidal roof surface 4A and a triangular roof surface 4B that are divided by a horizontal flat building 2 and an inclined building 3 that branches off from both ends.

All the roof surfaces 4A, 4B are inclined downward with the same inclination toward the eaves, and the width of the unitized roof panel 6 in which roof tiles 5 have been previously roofed in the factory or the like. By joining each other in the direction,
It is formed flush with a certain gradient. Each roof panel 6
Is lifted by a crane or the like at a construction site and assembled into a shed assembly of a building not shown, and the roof surfaces 4A and 4B are constructed by joining a plurality of roof panels 6 flush with each other on the shed assembly. To be done.

As shown in FIG. 2, each roof panel 6 is provided with a plywood base plate 7 and a plurality of rafters 8 fixed to the lower surface of the base plate 7 along the roof flow direction. A waterproof sheet 9 made of asphalt roofing or the like is laid on the entire upper surface of 7. The roof tile 5 is raised on the waterproof sheet 9 by nailing or the like, and its installation range is set to be a range that is cut off from the edge in the panel width direction by the amount of the joint 10. That is, although the waterproof sheet 9 is attached to the upper surface of each roof panel 6 and to the end portion in the width direction, the roof tiles 5 are not thatched, so that the joint portion 10 with another roof panel 6 is substantially constant. The width is left.

The roof tiles 5 are arranged in each row so that the ends in the width direction of the roof tiles are abutted against each other, and the roof tiles 5 are piled up so that the roof tiles are sequentially stacked upward from the lower direction to the upper direction. The roof tiles 5 in the odd-numbered rows and the even-numbered rows from the bottom in the same direction are arranged so that their pitches are offset by half the width. As shown in FIG. 1, when the roof panels 6 are joined together to form the roof surfaces 4A, 4B, the roof tiles 5 on one roof surface 4A, 4B are arranged so that the joints cannot be identified from the outside. The roofing patterns are joined so as to be continuous. That is, each roof surface 4A,
4B is a roof tile by inserting a joining piece 11 obtained by cutting the roof tile 5 into an appropriate width direction into a joint portion 10 of both roof panels 6 and 6 arranged so that their widthwise ends are abutted to each other. It is constructed so that the roofing pattern of 5 is continuous.

1 and 4 to 7, the roof tiles 5 drawn in white are the roof panels 6 in advance in a factory or the like.
The roof tiles installed in the above are shown, and the tiles whose interior is hatched are the joining pieces 11 that are inserted at the site after joining the roof panels 6. As shown in FIG. 3 (a), the roof tile 5 used in this embodiment is made of ceramic plate material having an overall shape of a substantially pentagonal flat plate, and has a vertical groove 12L extending from its lower edge to the center. 12R are formed at two positions in the width direction, and the vertical grooves 12L and 12R are formed at positions that divide the roof tile 5 into three in the width direction.

Further, each of the joining pieces 11 of this embodiment is formed by cutting the roof tile 5 at any position of the left and right vertical grooves 12L, 12R.
As shown in (b), the left and right first and second joining pieces 11 obtained when the left vertical groove 12L is divided into two parts.
A, 11B and left and right third and fourth joining pieces 11C, 1 obtained when divided in two at the right vertical groove 12R
There are four types, 1D.

As shown in FIG. 1, in the roof building roof 1, the center 13 of the pillars located at the corner of the building is located directly below the sloping building 3, and the roof is the distance between the centers 13 of the pillars. A reference width L of the surfaces 4A and 4B is set, and the reference width L is the width Wi of each roof panel 6 and the width D of the roof tile.
At the same time, it is set to a positive integer multiple with respect to the module width a having a constant length.

That is, between the width D of the roof tile 5, the width Wi of each roof panel 6 and the reference width L of the roof surface 4, D = a × l (ell) Wi = a × mi (in the present embodiment, i = 1 to 4) L = a × n However, the relationship that l _, mi _{, and} n are positive integers that satisfy l <mi <n is established.

4 to 7 show each roof panel 6 in which the width Wi and the installation pattern of the roof tiles 5 are set under such conditions. Among these, the roof panel 6A shown in FIG. 4 is shown. Is a basic panel set to the most frequently used basic width size, and the roof panel 6B shown in FIGS.
It is an adjustment panel used to cope with a change in the reference width L of the roof surfaces 4A and 4B.

Here, in the present embodiment, the module width a is set to 305 mm, and for this width a m1 =
6, m2 = 5, m3 = 4, m4 = 3, l (el) = 2. That is, the width D of the roof tile 5 is a × 2 = 6
The width W1 of the basic panel 6A is set to 10 mm and is set to a × 6.
= 1830 mm, and the width of each adjustment panel 6B is smaller than W1 by a by W2 = a × 5 = 1525 mm, W3 = a
It is set to x4 = 1220 mm and W4 = a * 3 = 915 mm, respectively.

Even if the width D of the roof tile 5 and the width Wi of the roof panel 6 are strictly set to integral multiples of the module width a, the roof tile 5 and the roof panel 6 cannot be properly arranged in the field construction. Therefore, in practice, it is preferable that the width D of the roof tile 5 and the width Wi of the roof panel 6 are set to be slightly smaller than the above-mentioned design dimensions. That is, in practice, the roof tiles 5 are arranged at intervals of several millimeters, and therefore D = 600 mm is set in anticipation of this. Also, regarding the width Wi (i = 1 to 4) of each roof panel 6A, 6B,
Actually, the size is made smaller by about 4 mm than the above size in consideration of an assembly error in the field.

In this way, considering the assembling error and some dimensional error in the field construction, the roof tile 5 width D and the roof panel 6 width Wi may be an integral multiple of the module width a. The same applies to the reference width L of 4A and 4B. Under the above-described dimension setting, first, the installation pattern of the roof tiles 5 on the basic panel 6A can be specified to four types shown in FIG.

That is, in FIG. 4 (A), the roof tiles 5 in odd rows from the bottom are arranged from the left end of the panel 6A by a / 2 shift to the right, and the first joining piece 11A is arranged on the rightmost side. I am doing it. In addition, roof tiles 5 from the bottom in even rows
Are arranged from the left end of the panel 6A by 3a / 2, and the fourth joining piece 11D is arranged on the leftmost side. Therefore, in the joint portions 10 on both the left and right sides in this case, the third joint piece 11C is formed on the second joint piece 11B.
Is a joint pattern J1 that overlaps.

In the installation patterns of FIGS. 4B, 4C, and 4D, the installation pattern of FIG. 4A is further shifted by a / 2 to the right in FIG. In the joint pattern J2 of B), the first and fourth joint pieces 11A and 11D are overlapped on the second joint piece 11B. In the following, in the joint pattern J3 of FIG. 4C, the second joint piece 11B overlaps the third joint piece 11C, and in the joint pattern J4 of FIG. 4D, the first and fourth joints are sequentially formed. Piece 11A, 1
The second joining piece 11B overlaps 1D.

Further, in this case, the width W1 of the basic panel 6A
(= 6a) is an integer multiple of the width D (= 2a) of the roof tile 5 (3
Therefore, the joint portions 10 on both the left and right sides have the same joint pattern Ji (i = 1 to 4). On the other hand, in the case of the adjustment panel 6B with W2 = 1525 mm, the panel width W2 (= 5a) is the width D of the roof tile 5.
Since it is not an integral multiple of 2.5 times (= 2a),
As shown in FIG. 5, the joint patterns Ji on the left side and the right side of the panel 6B are different from each other. However, in this case, the left joint pattern Ji
(I = 1 to 4) are set in the same order as the joint pattern Ji of the basic panel 6A.

Further, the adjustment panel 6 with W3 = 1220 mm
In the case of B, the panel width W3 (= 4a) is the roof tile 5
Since it is an integer multiple of twice the width D (= 2a), the joint pattern Ji is the same on both the left and right sides of the panel 6B, as in the case of the basic panel 6A, as shown in FIG. Further, in the case of the adjusting panel 6B with W4 = 915 mm, the panel width W4 (= 3a) is the width D of the roof tile 5.
(= 2a) is 1.5 times, which is not an integral multiple,
As shown in FIG. 7, the joint patterns Ji on the left side and the right side of the panel 6B are different from each other. However, in this case, the right joint pattern Ji
(I = 1 to 4) are set in the same order as the joint pattern Ji of the basic panel 6A.

As described above, in this embodiment, not only the width Wi of each roof panel and the width D of the roof tile but also the roof surfaces 4A and 4B.
The reference width L is set to a positive integer multiple with respect to the module width a having a constant length, and thus the width Wi (i = i = i) of the adjustment panel 6B to be arranged midway in the width direction of the roof surfaces 4A and 4B.
2, 3, 4) is changed by the module width a, the reference width L of the roof surfaces 4A, 4B is also changed by the module width a, and at the same time, only four joint patterns are provided. The installation pattern of the roof tiles 5 can be set so as to be J1 to J4, and it is not necessary to fundamentally change the installation pattern of the roof panel 6.

For example, the trapezoidal roof surface 4A of the parquet roof 1 shown in FIG. 1 has a basic width L = a × 33, while five basic panels 6A unified to have the same width W1.
It is constructed by joining together one adjustment panel 6B having a width W3 = 915 mm, but the basic width L is ax
When changing to 34, instead of the adjustment panel 6B with W4 = 915 mm, the adjustment panel 6B with W3 = 1220 mm
Should be adopted.

Further, in the parquet roof 1 shown in FIG. 1, the adjusting panel 6B is arranged so as to be biased next to the triangular basic panel 5A which is arranged in the middle of the roof surface 4A in the width direction and at the end in the same direction. As a result, only the basic panel 6A having the same roof tile 5 installation pattern can be used as much as possible on one roof surface 4A, and there is an effect that the panel processing time can be further reduced.

That is, in this case, since the adjustment panel 6B with W4 = 915 mm is adopted, the joint pattern is different between the left and right as described above, and in addition, as shown in FIG.
Type adjustment panel 6B has J1 on the left and J on the right.
4 is the basic panel 6A of FIG. 4 (A) type on the left side of the adjustment panel 6B, and the basic panel 6A of FIG. 4 (C) type is on the right side of the adjustment panel 6B.
Must be joined.

However, even with such an adjustment panel 6B, when the adjustment panel 6B is arranged on one side of the roof surface 4A, for example, as shown in FIG. It is possible to arrange only 5) type basic panels 6A. On the other hand, when the adjustment panel 6B of W4 = 915 mm is arranged at the center of the roof surface 4A, the basic panel 6A of the type (A) and the type (C) of FIG. Since three pieces are arranged side by side, it is necessary to create the same number of basic panels 6A having different arrangement patterns.

Further, in this embodiment, in the basic panel 6A in which the joint portions 10 are formed at the both ends in the width direction, the roof is such that the joint patterns Ji (i = 1 to 4) are the same for both joint portions 10. Since the installation pattern of the roof tile 5 is set and the basic panel 6A having such a pattern is continuously used as shown in FIG. 1, the type of the joining piece to be used can be the same for all the joining portions 10, The labor of working the joining piece 11 can be reduced, and the work of inserting the joining piece 11 in the field can be prevented from becoming complicated, and the labor required for construction can be reduced.

As the basic panel 6A in which those having the same width are continuously arranged, in addition to the one having W1 = 1830 mm, an integral multiple of the width D of the roof tile 5 (for example, W3 = 122 shown in FIG. 6).
If the width of the basic panel 6A is too small, the roof tile 5 that should be installed beforehand is sufficient.
In this embodiment, the roof tile 5 has a width D of 610 mm because the amount of the roof tile 5 is reduced and the work on the site is increased, and when the width of the basic panel 6A is too large, the weight becomes excessive and the lifting work becomes difficult. In the case of, the basic panel 6A has W1 = 1830
It is preferable to set it to about mm.

In the case of the gathering roof 1, the roof surface 4
The roof panel 6 arranged at the widthwise ends of A and 4B is shown in FIG.
The width W of the lower end is the width W i of the roof panel 6 arranged in the width direction of the roof surfaces 4A and 4B plus the eavement dimension w from the center 13 of the pillar. It is set to one. Further, according to the present embodiment, as described above, each of the joining pieces 11A to 11D is formed by dividing the roof tile 5 into two in the width direction, and moreover, each of the joint patterns J1 to J1 formed by them. J
With respect to 4, since the joining pieces 11 to be inserted in the odd-numbered rows and the joining pieces 11 to be inserted in the even-numbered rows have the same length in the width direction, as shown in FIG. As a result, the joining work is facilitated, and the lengths of the joining pieces 11 in the width direction are uniform, which makes it easy to stack and convey them.

The present invention is not limited to the above-mentioned embodiments. For example, the present invention is not limited to the gable roof 1 such as a gable roof or a half gable roof, and has a complicated shape having a valley. It can also be used for roofs. Further, the present invention can be applied to a roof tile without a groove and a roof tile other than a flat roof tile.

[0040]

As described above, according to the present invention,
By adjusting the reference width L together with the width Wi of the roof panel 6 by the module width a, the adjustment panel 6B for setting the roof surfaces 4A and 4B to the reference width L is provided with the roof surfaces 4A and 4A.
Even when it is arranged in the widthwise direction of B, the roof surface 4
The change in the reference width L of A and 4B can be dealt with only by the roof panel 6 having the preset installation pattern of the roof tiles 5, so that the design and the construction cost in constructing the roof 1 can be reduced ( Claims 1 and 3).

When the installation pattern of the roof tiles 5 is set so that the joint pattern Ji by the joining pieces 11 is the same for both joints 10, the roof panel 6 having this pattern is continuously used as the basic panel 6A. By doing so, the type of the joining piece 11 to be used can be made the same for each joining part 10, so that the labor of working the joining piece 11 can be reduced and the insertion work of the joining piece 11 on the site can be prevented from becoming complicated. The construction work can be reduced (claim 2).

Further, a plurality of basic panels 6A having the same width W1
And widths W2, W3, W4 smaller than the basic panel 6A
When the roof surfaces 4A and 4B having the reference width L are formed by joining the adjustment panels 6B and the adjustment panels 6B to each other, the adjustment panel 6B is biased toward the one end in the width direction midway of the roof surfaces 4A and 4B. By arranging them in positions, it becomes possible to use only the basic panel 6A having the same roof tile 5 installation pattern on one roof surface 4A, 4B as much as possible, which in turn saves time and labor for processing the panel 6A. It can be further reduced (Claim 4).
