Abstract

PURPOSE: To simplify the joining operation and conveyance operation of joining pieces by preventing the change of size in the cross direction of the joining pieces in odd rows and even rows. CONSTITUTION: In a roof panel, in which joining pieces 11 formed by cutting roofing tiles 5 in proper length in the cross direction so that roofing patterns are continued among other mutually connected roofing panels 5 are inserted to joining sections 10 in roof panels 6, in which width pitches are displaced among odd stages and even stages so that the joining sections 10, in which the roofing tiles 5 are not roofed at end sections in the cross direction, are left and the roofing tiles 5 are roofed, the joining pieces 11 are formed by dividing the roofing tiles 5 into two in the cross direction. Accordingly, the mounting pattern of the roofing tiles 5 is set so that length in the cross direction of the joining pieces 11 inserted to the formed odd rows and the joining pieces 11 inserted to the even rows is equalized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof panel used for constructing a roof of a building.

[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]

In the technique described in the above publication, the joining pieces obtained by dividing the roof tile into three parts are inserted into odd rows, and the joining pieces obtained by dividing the roof tile into two rows are arranged in even rows. The joining pieces to be inserted in the odd-numbered rows and the joining pieces to be inserted in the even-numbered rows have different lengths in the width direction.

In this case, since the insertion dimension of the joining piece at the site is different between the odd number row and the even number row, the method of handling the joining piece varies from row to row, such as the nailing place changes from row to row. The joining process was complicated. Also, if the width direction length of the joining piece is two types,
When the joining pieces are stacked and conveyed in the order of insertion, the lengths in the width direction of the joining pieces are not uniform, which makes it difficult to stack and convey the joining pieces.

In view of the above situation, an object of the present invention is to simplify the joining work and the carrying work by keeping the widthwise dimensions of the joining pieces between the odd-numbered rows and the even-numbered rows.

[0007]

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 steps and the even-numbered steps so as to leave a joint where the roof tiles are not roofed at the ends in the width direction. In such 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, so that the roofing pattern is continuous with other roof panels joined to each other, The joining piece is formed by dividing the roof tile into two pieces in the width direction, and the roof piece is formed so that the joining pieces to be inserted in the odd rows and the joining pieces to be inserted in the even rows have the same width direction. A roof tile installation pattern is set (claim 1).

In this case, as the roof panel, joints are 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).

[0009]

In the present invention, the joining piece 11 is formed by dividing the roof tile 5 into two pieces in the width direction, and the width of the joining piece 11 inserted into the odd row and the joining piece 11 inserted into the even row formed by this. The installation pattern of the roof tiles 5 is set so that the direction lengths are the same (Fig. 4
To FIG. 7).

Therefore, for example, as shown in FIG. 4, the insertion dimension δ of the joining pieces 11 in each row is the same, and the handling of the joining pieces 11 is prevented from changing from row to row. Further, since the joining pieces 11 in each row have the same length in the width direction, when the joining pieces 11 are stacked and conveyed in the insertion order, the joining pieces 11 are
The widthwise length of the can be made uniform.

[0011]

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 and 4B are inclined downward toward the eaves with the same inclination, and the width of the roof panel 6 is a unitized roof panel 6 in which roof tiles 5 have been previously roofed in the factory. 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 includes 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 tile 5 are abutted against each other, and the roof tiles 5 are roofed so as to be 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 roof tiles installed in advance on the roof panel 6 in a factory or the like, and the inside is hatched with diagonal lines. The roof tile presents the joining piece 11 which is inserted in the field after joining the roof panel 6. As shown in FIG. 3 (a), the roof tile 5 used in this embodiment is made of a 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 joining piece 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 gathering roof 1, the center 13 of the pillar arranged at the corner of the building is located directly below the sloping ridge 3, and the roof is defined as 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, and among them, 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 being shifted to the right by a / 2, 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.

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 tiles 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.

In addition, in the parquet roof 1 shown in FIG. 1, the adjustment panel 6B is arranged in a biased manner 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 of W4 = 915 mm is adopted, the joint pattern is different between the left and right as described above, and further, 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 so as to be offset to 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 the present embodiment, in the basic panel 6A in which the joint portions 10 are formed at 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.

[0036]

As described above, according to the present invention,
Since the insertion dimension δ of the joining pieces 11 in each row is the same, the joining work is simple and the lengths of the joining pieces 11 in the width direction can be aligned and overlapped.
The work of transporting the joining piece 11 is also simplified (Claim 1).

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).
