DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[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 a rise in construction costs,
2. Description of the Related Art A unitized roof panel in which a roof tile is previously laid at a factory or the like is employed. The roof panel is lifted by a crane or the like at a construction site and assembled into a cabin of a building, and a plurality of roof panels are joined to each other on the cabin to form a roof surface having 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 surface, and the labor on the on-site work can be saved (Japanese Patent Application Laid-Open No. H5-295832). Reference).

In such a panel construction method using a unitized roof panel, aesthetic treatment is performed so that a joint portion of the roof panel cannot be identified from the outside, and
In order to improve the waterproof property at that portion, there is a case where the roof panels are joined so that the roof tile pattern on one roof surface is continuous. The roof panel in this case is
The roof tiles are laid with the pitches in the odd and even rows shifted in the width direction so that the joints where the roof tiles are not laid are left at the width direction ends of the upper surface. By inserting a joint piece obtained by cutting the roof tile into an appropriate width direction into a joint portion of the roof panel, the roof tile is constructed so that the roof tile pattern is continuous (for example, see Japanese Unexamined Patent Application Publication No. No. 84152).

[0004]

As described above, when joining the 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, In addition, the installation pattern of the roof tiles in each roof panel can be made uniform. On the other hand, in residential buildings, functional objects such as daylighting windows (top lights), ventilation towers, and dormers may be provided on the roof surface. By attaching the accessory, the labor of constructing the accessory on site can be omitted.

[0005] However, since the installation position of such a functional accessory varies in accordance with the intention of a customer or a designer, the position in the width direction of the roof panel to which the functional accessory is attached fluctuates arbitrarily. The width of any of the roof panels constituting the roof surface will also vary to an arbitrary width, and in some cases, the width of the roof panel may be about the width of a roof tile.

As described above, when the roof panel is about the same width as the roof tile, it is necessary to form the roof panel by precisely arranging only the joining pieces on the upper surface.
Since the time required to create the roof panel is often higher than the time required to construct the panel on site, the labor required for the entire roof construction is rather increased. In addition, if the width of the roof panel fluctuates arbitrarily, the joint pattern of the joining pieces will also change, so even in such cases, if you try to thoroughly implement the panel construction method where only the joints are installed on site, the roof surface will be configured It is necessary to redesign the roof tile installation pattern for all roof panels from the beginning, and if the roof tile installation pattern (joint pattern) is different from the standardized one, it will handle the pattern that the operator is not used to And the joining work of the roof panels becomes complicated.

The present invention has been made in view of the above circumstances, and when a roof panel having the same width as a roof tile is generated due to a positional relationship with a functional accessory or the like, it is possible to reduce the labor required for the entire roof construction. The primary purpose is to do so. In addition, the present invention is designed so that even if the width direction position of the roof panel fluctuates due to the positional relationship with the functional accessory, etc., the roof panel of the roof tile installation pattern standardized in advance can be used as much as possible. A second object is to reduce the construction cost.

[0008]

In order to achieve the above object,
The present invention has taken the following technical measures. That is, the present invention provides a roof panel in advance by shifting the pitch in the width direction between the odd rows and the even rows so as to leave a joint portion where the roof tile is not roofed at the width direction end. The roof panel is joined to each other at the joint portion to form a roof surface flush with the joint, and a joint piece obtained by cutting the roof tile to an appropriate width direction length is inserted into the joint portion. In a method for constructing a roof of a building in which a roofing pattern between the roof panels joined to each other is continuous, a tileless panel having a width equal to or less than the width of the roof tile and having the roof tile not covered is provided. In the joining step of arranging at an arbitrary position in the width direction of the roof surface and thereafter inserting a joining piece into a joining portion of each of the roof panels, the roof tile and the joining piece or any of these pieces are placed on the upper surface of the tileless panel. Wherein the or wipe one (claim 1).

In this case, the installation pattern of the roof tiles to be laid on the roof panel in advance is set to several types that are shifted by a certain length in the width direction for the reason described later, and the width of the tile-free panel is set to the certain length. It is preferable to set so as to be a multiple (claim 2). In addition, it is desirable to dispose the tileless panel at a position halfway in the width direction of the roof surface and at a position deviated to one end side in the same direction.

[0010]

According to the first aspect of the present invention, in the joining step performed in the on-site construction, the roof tile 5 and the joining piece 11 or the roof tile 5 or the joining piece 11 are provided on the upper surface of the tileless panel 22 arranged at an arbitrary position in the width direction of the roof surface 4A. Since either one of them is roofed, there is no need to create a roof panel 6 having the same width as the roof tile 5 which is troublesome to create (claim 1).

According to the second aspect of the present invention, the roof panel 6
The installation patterns of the roof tiles 5 to be roofed in advance are set to several types that are shifted by a constant length δ in the width direction (in the embodiment, all four types of joint patterns J1 to J4 shown in FIGS. 4 to 7). In addition, since the width w of the tileless panel 22 is set to a multiple of the constant length δ, the width w of the tileless panel 22 must be set in advance as long as the width w of the panel 22 changes in units of the constant length δ. It conforms to any one of the joint patterns J1 to J4, and there is no need to fundamentally change the installation pattern of the roof tile 5 on the roof panel 6 in response to a change in the width w of the tileless panel 22.

Furthermore, if the tile-less panel 22 is arranged in the middle of the roof surface 4A in the width direction and at a position deviated toward one end in the same direction, only the basic panel 6A having the same installation pattern of the roof tile 5 can be used. It can be used as much as possible on one roof surface 4A (claim 3).

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a development view of a roof 1 of a building to which the present invention is applied. This roof 1 is a so-called ridge roof,
It has trapezoidal roof surfaces 4A and 4B and a triangular roof surface 4C divided by a horizontal flat building 2 and an inclined building 3 branched from both ends.

The roof surfaces 4A, 4B and 4C are all inclined downward at the same inclination toward the eaves.
The upper trapezoidal roof surface 4B in FIG. 1 and the right and left triangular roof surfaces 4C in FIG. 1 are joined to each other only in the width direction of a unitized roof panel 6 in which a roof tile 5 is previously laid on the upper surface in a factory or the like. As a result, they are formed flush with a constant gradient.

On the other hand, the trapezoidal roof surface 4A on the lower side of FIG.
Since the lighting window 21 as a functional accessory is installed at the position shown in the figure, the roofless panel 2 having no roof tile 5 on the upper surface thereof
2 are arranged. In addition, as a functional accessory, there are a ventilation tower, a dormer, and the like in addition to the lighting window 21 illustrated in FIGS. 1 and 2. Each roof panel 6 and tile-less panel 22 are lifted by a crane or the like at a construction site and assembled into a hut set of a building (not shown), and a plurality of roof panels 6 are joined to each other on this hut set in a plane. , The roof surface 4
A, 4B and 4C are constructed.

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 roofed on the waterproof sheet 9 by nailing or the like, and its installation range is set to a range that is reduced by an amount corresponding to the joint portion 10 from the end in the panel width direction. That is, the waterproof sheet 9 is attached to the upper surface and the width direction end of each roof panel 6, but the roof tile 5 is not covered, so that the joint 10 with the other roof panel 6 is almost constant. The width is left.

On the roof panel 6 shown on the left side of FIG. 2, the lighting window 21 is provided in advance in a factory or the like, and the center of the lighting window 21 in the width direction coincides with the center of the roof panel 6 in the same direction. It is arranged to be. The roof tiles 5 are arranged so that the widthwise ends of the roof tiles abut in each row, and are roofed in such a manner that the roof tiles 5 are sequentially stacked upward from below in the roof flow direction. The odd-numbered rows and the even-numbered rows of roof tiles 5 are arranged so that the pitch is shifted by half of the width from the bottom.

As shown in FIG. 1, each roof panel 6 has a single roof surface 4A, 4B so that when the roof panels 6 are joined to form the roof surfaces 4A, 4B, 4C, the joints cannot be identified from the outside. , 4C so that the roofing pattern of the roof tile 5 is continuous. That is, each roof surface 4
A, 4B, and 4C insert a joint piece 11 obtained by cutting the roof tile 5 into an appropriate width direction length into a joint portion 10 of both roof panels 6 and 6 arranged with their ends in the width direction. Thus, the roof tiles 5 are constructed so that the roofing pattern is continuous.

In FIGS. 1 and 4 to 7, the roof tiles 5 drawn in white are previously covered with a roof panel 6 by a factory or the like.
, And the tiles hatched inside with diagonal lines indicate the joining pieces 11 to be inserted on site after the joining of the roof panels 6. Thus, this specification
The roof panel 6 is a roof tile 5 on a base plate 7
But the connecting piece 11 is not yet
It means a panel with no state. As shown in FIG. 3A, the roof tile 5 employed in the present embodiment is made of a ceramic plate having a generally pentagonal flat shape, and has vertical grooves 12L extending from the lower edge to the center. 12R are formed at two places in the width direction, and the vertical grooves 12L and 12R are formed at positions where the roof tile 5 is divided into three in the width direction.

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

As shown in FIG. 1, in the ridge roof 1, a center 13 of a pillar disposed at a corner of the building is located directly below the inclined ridge 3, and the distance between the centers 13 of the pillar is a roof. The 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 constant module width a.

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 this embodiment, i = 1 to 4) L = a × n where l _, mi _{, and} n are positive integers satisfying l <mi <n.

FIGS. 4 to 7 show the respective roof panels 6 in which the width Wi and the installation pattern of the roof tile 5 are set under the above conditions. Among them, the roof panel 6A shown in FIG. Is a basic panel set to the most frequently used basic width size, and the roof panel 6B shown in FIGS.
This 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 m 1 =
6, m2 = 5, m3 = 4, m4 = 3, 1 (ell) = 2. That is, the width D of the roof tile 5 is a × 2 = 6.
The width W1 of the basic panel 6A is a × 6.
= 1830 mm, and the width of each adjustment panel 6B is smaller than W1 by a, W2 = a × 5 = 1525 mm, W3 = a
× 4 = 1220 mm and W4 = a × 3 = 915 mm.

If the width D of the roof tile 5 or the width Wi of the roof panel 6 is strictly set to an integral multiple of the module width a, the roof tile 5 or the roof panel 6 cannot be properly arranged in the on-site construction. In practice, it is preferable to set the width D of the roof tile 5 and the width Wi of the roof panel 6 to be slightly smaller than the design dimensions described above. That is, since the roof tiles 5 are actually arranged at intervals of several millimeters, D is set to 600 mm in anticipation of this. Also, for the width Wi (i = 1 to 4) of each roof panel 6A, 6B,
Actually, the size is reduced by about 4 mm from the above-mentioned size in consideration of a mounting error at the site.

As described above, in consideration of an assembly error and a slight dimensional error in the on-site construction, the width D of the roof tile 5 and the width Wi of the roof panel 6 may be almost 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 tile 5 for the basic panel 6A can be specified to four types shown in FIG.

That is, in FIG. 4A, the roof tiles 5 in odd rows from the bottom are δ = a / 2 (15) from the left end of the panel 6A.
The first joining pieces 11A are arranged at the rightmost position by being shifted to the right by 2.5 mm). In addition, even-numbered rows of roof tiles 5 from the bottom are 3 from the left end of panel 6A.
Arranged from a position shifted by δ = 3a / 2, the fourth joint 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 second joint piece 1
A joint pattern J1 in which the third joint piece 11C is overlapped on 1B.

In the installation patterns of FIGS. 4B, 4C and 4D, the installation pattern of FIG.
4 are shifted to the right in the figure by two, and FIG. 4 (B)
In the joint pattern J2, the first and fourth joint pieces 11A and 11D overlap the second joint piece 11B. Hereinafter, in the joint pattern J3 of FIG. 4C, the second joint piece 11B is overlapped on the third joint piece 11C, and in the joint pattern J4 of FIG. Peace 11
The second joining piece 11B is configured to overlap the first and second joining pieces 11A and 11D.

In this case, the width W1 of the basic panel 6A is
(= 6a) is an integral multiple (3) of the width D (= 2a) of the roof tile 5.
), 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 of W2 = 1525 mm, the panel width W2 (= 5a) is equal to the width D of the roof tile 5.
(= 2a) 2.5 times and not an integral multiple,
As shown in FIG. 5, the joint patterns Ji are different from each other on the left and right sides of the panel 6B. 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 of W3 = 1220 mm
In the case of B, the panel width W3 (= 4a) is
6, which is an integral multiple of twice the width D (= 2a), as shown in FIG. 6, the same joint pattern Ji is formed on both the left and right sides of the panel 6B as in the case of the basic panel 6A. Further, in the case of the adjustment panel 6B having W4 = 915 mm, the panel width W4 (= 3a) is equal to the width D of the roof tile 5.
(= 2a) 1.5 times and not an integral multiple,
As shown in FIG. 7, the joint patterns Ji are different from each other on the left and right sides of the panel 6B. 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.

It is to be noted that, as for these adjustment panels 6B, the point that the roof tiles 5 are shifted to the right by δ = a / 2 as the installation pattern shifts from A to D is the same as the case of the basic panel 6A. . Further, in the case of the ridge roof 1, the roof panel 6 disposed at the width direction ends of the roof surfaces 4A, 4B, and 4C has a triangular shape as shown on the right side of FIG. It is specified by the width Wi of the roof panel 6 arranged halfway in the width direction of the roof surfaces 4A, 4B, and 4C, plus the eaves dimension p from the center 13 of the pillar.

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 4B and 4C.
Is set to a positive integer multiple with respect to the module width a of a fixed length, the width Wi (i = i) of the adjustment panel 6B to be arranged halfway in the width direction of the roof surfaces 4B and 4C.
2, 3, 4) is changed by the module width a, the reference width L of the roof surfaces 4B, 4C is also changed by the module width a, and only four types of joint patterns are used in total. The installation pattern of the roof tile 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, in the case of the trapezoidal roof surface 4B on the upper side of FIG. 1, the basic width L = a × 30, whereas the five basic panels 6A unified to the same width W1 = a × 6. Are joined together, but when the basic width L = a × 28, four basic panels 6A unified to the same width W1 = a × 6 and W3 = a × 4 And one adjustment panel 6B.

On the other hand, the trapezoidal roof surface 4 on the lower side in FIG.
In A, the position of the daylighting window 21 is slightly shifted to the right, so that the basic width L is a × in the same manner as the trapezoidal roof surface 4B on the upper side in FIG.
Even if it is 30, when the roof panel 6 (basic panel 6B) is arranged in the same manner as the roof surface 4B, the lighting window 21 matches the panel joint portion. I have to do it.

Therefore, in the present embodiment, the basic panel 6A having the lighting window 21 is disposed slightly to the right of the roof surface 4A in accordance with the position of the lighting window 21, and accordingly, each roof panel 5 and no tiles are provided. The panel 22 is arranged as follows. Further, in this case, the installation patterns A to D of the roof tile 5 in the roof panel 6 are set to four types that are shifted by a certain length δ in the width direction as described above, whereas The width w is set so as to be a multiple of δ.

That is, in forming the trapezoidal roof surface 4A on the lower side in FIG. 1, the width W1 = a × 6 in order from the left side.
Triangular basic panel 6A, adjustment panel 6B of width W4 = a × 3, tileless panel 22 of width w = δ, width W1 = a × 6.
Basic panel 6A, basic panel 6A of width W1 = a × 6,
A tileless panel 22 having a width w = δ × 4, a tileless panel 22 having a width w = δ, and a triangular basic panel 6A having a width W1 = a × 6.
Are arranged side by side.

Then, with respect to each of the roof panels 6 and the tile-less panels 22 arranged as described above, in the joining step performed at the site where the joining pieces 11 are inserted into the joining portions 10 of the respective roof panels 6, the respective tile-less panels 22 are The joining piece 11 is also laid on the upper surface. As described above, in the case where a panel having a width w = δ or w = δ × 4 and a width D or less of the roof tile 5 is generated as a component of the roof surface 4A, this panel is referred to as a tile-less panel 22 that does not cover the roof tile 5. Since the joining piece 11 is laid on the upper surface of the tileless panel 22 in the joining process performed at the site, the roof panel 6 having the same width as the roof tile 5 which has been troublesome to create is created. This eliminates the need to perform the work, thereby reducing the labor required for the roof construction as a whole.

Further, since the width w of the tileless panel 22 is set to be a multiple of the shift amount δ of the installation pattern of the roof tile 5 on the roof panel 6, the width w of the tileless panel 22 is set to a certain length δ. As long as it is changed as a unit, as shown in FIG.
Complies with J4. For example, in the case of the roof tile 4B on the lower side of FIG. 1, the leftmost triangular panel is a basic panel 6A of the type shown in FIG. 4A and the right side thereof is an adjustment panel 6B of the type shown in FIG. However, since a tileless panel 22 having a width δ is interposed on the right side of the adjustment panel 6B, two basic panels 6A of the type shown in FIG. Are joined.

Furthermore, a tileless panel 22 having a width of 4δ and δ is interposed on the right side of the basic panel 6A, so that the rightmost triangular panel is the basic panel 6 of FIG.
A. As described above, according to the present embodiment, as long as the width w of the tileless panel 22 is changed in units of its fixed length δ, the width w always matches one of the joint patterns J1 to J4. Even if the width changes, a design change that fundamentally changes the arrangement pattern of the roof tiles 5 on the roof panel 6 becomes unnecessary, and the operator can use the standardized joint pattern J as usual.
It is enough to perform the joining work at 1 to J4.
Is also simplified.

In FIG. 1, only the joining pieces 11 are roofed on the tile-less panel 22. However, when the width w = δ × 4, the arrangement pattern of the roof tile 5 on the roof panel 6 side is different. In some cases, the uncut roof tile 5 can be installed as it is on the tile-less panel 22 as well. Further, as shown in FIG. 10, in the case of the tileless panel 22 having a width w of less than w = δ × 4 = 610 mm, the tileless panel 22 is composed of only plywood 23 without rafters. The plywood 23 is supported by a receiving bar 24 fixed to the side of the rafter 8 of the roof panel 6. This is because the maximum width of the plywood 23 that can receive the load of the roof without supporting the rafters is 610 mm. Therefore, it is necessary to provide a rafter in the tileless panel 22 having a width equal to or more than this width, but to make the panel into a panel. In this case, it is not necessary to support the tileless panel 22 itself with rafters.

On the other hand, in the ridge roof 1 shown in FIG. 1 in this embodiment, the tileless panel 22 is located halfway in the width direction of the roof surface 4A and next to the triangular basic panel 5A arranged at the end in the same direction. It is arranged to be biased. in this case,
The reason that the tileless panel 22 is arranged not in the end of the roof surface 4A but in the width direction is that the width w of the panel 22 is usually smaller than the eaves dimension p.
This is because if the panel 22 is disposed at the end in the width direction of A, the panel 22 cannot be supported by a supporting member such as a pillar on the building body side.

The reason why the tile-less panel 22 is arranged adjacent to the triangular basic panel 5A is that the basic panel 6A having the same installation pattern of the roof tile 5 can be provided on one roof surface 4A. This is because it can be used as much as possible, and has the effect of further reducing the processing time of the panel.
That is, since the tile-less panel 22 has only a width w equal to or less than the width D of the roof tile 5, the installation pattern of the roof tile 5 on the roof panel 6 changes with the panel 22 as a boundary.

However, even if such a tileless panel 22 is arranged so as to be biased to one side of the roof surface 4A, for example, as shown in FIG. Only five (C) type basic panels 6A can be arranged. On the other hand, when the tileless panel 22 is arranged at the center of the roof surface 4A, as shown in FIG.
The (A) type and (C) type basic panels 6A are arranged three by three on the left and right sides of the tile-less panel 22, and it is necessary to create the same number of basic panels 6A having different installation patterns.

The basic panels 6A having the same width continuously arranged include W1 = 1830 mm and an integral multiple of the width D of the roof tile 5 (for example, W3 shown in FIG. 6).
If the width of the basic panel 6A is too small, the amount of the roof tiles 5 to be installed in advance is reduced, and the on-site work is increased.
If the width of the basic panel 6A is too large, the weight becomes excessively large and the lifting work becomes difficult.
In the case of the present embodiment, which is 0 mm, the basic panel 6A has W1 =
It is preferable to set it to about 1830 mm.

It should be noted that the present invention is not limited to the above-described embodiment. For example, the present invention is not limited to a gable roof or a half gable roof other than the ridge roof 1 or a complex shape having a valley. It can also be used on roofs. Further, the present invention can be applied to a roof tile having no groove or a roof tile other than a flat roof tile.

[0046]

As described above, according to the present invention,
Since it is not necessary to create the roof panel 6 having the same width as the roof tile 5 which requires much time to make, it is possible to reduce the labor of the entire roof construction as compared with the related art. According to the second aspect of the present invention, it is not necessary to redesign the installation pattern of the roof tile 5 on the roof panel 6 even if the width w of the tileless panel 22 changes, so that the design cost can be reduced. Since it is sufficient to perform the joining operation with the joint patterns J1 to J4 standardized as usual, the joining operation of the roof panel 6 can be simplified.

Furthermore, according to the third aspect of the present invention, only the basic panel 6A having the same installation pattern of the roof tile 5 can be used as much as possible on one roof surface 4A. The labor for processing the panel 6 can be reduced.
