Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof tile installation method for laying a tile on a roof having a corner ridge, and more particularly, to a roof tile installation method for laying using a plurality of types of adjustable corner tiles having a predetermined size. Regarding tile tiles.

[0002]

2. Description of the Related Art Conventionally, in the construction of a roof tile in which various tiles are laid on various roofs, when the laying of the cross tile is completed, the corner tile at the end of the corner ridge portion (or the end of the corner tile) becomes a fixed position. Therefore, it was necessary to lay roof tiles that were cut in accordance with the shape of the end tile in accordance with the corner ridge. However, it is not easy to cut the tile at the construction site itself,
Furthermore, cutting into a specific shape requires the skill of a craftsman, is also very difficult and often fails, generates a lot of waste materials, and furthermore, the cutting state of the cut tile becomes a small tile, so that the binding state is weak. Was.

[0003] The reason why cut roof tiles are required for various types of construction is as follows, and among them, the allocation is a second subject of the present invention. At the time of construction, it is originally necessary to allocate various tiles to the roof, but the size of the tiles (vertical and horizontal length, working length, working width), the area of the roof, the slope of the roof and the shape of the roof, Since the sizes and ratios are not fixed, the layout at the time of roofing on the roof is various, the construction is not easy, and the end tile has to be cut in accordance with the layout of the cross tile. Details that require various types of construction include, for example, the size of a single tile differs depending on the version, and even if the size of the tile is constant, the layout changes depending on the area and gradient of the roof. That is, while the area of the roof is displayed as a planar projection area, the actual construction area of the sloping roof surface is determined by the roof slope, so the width (working width of the tile) is the same between the two, The length in the direction (working length of the tile) and the area are different. Also, even though the actual size and the working dimensions of one or two cases are displayed for the size of the tile, the construction area differs depending on the roof area and slope, so a roof tile with a constant working area can be used on roofs with different construction areas. For good roofing, the calculation of the number of tiles and the allocation thereof have been complicated.

[0004]

SUMMARY OF THE INVENTION The present invention solves the problem that the layout is varied depending on the size of the tile, the area of the roof, and the slope of the roof, and the tiles to be laid in the corner building must be cut on site. The present invention provides a roof tile construction method and a corner tile.

[0005]

SUMMARY OF THE INVENTION The present invention is based on the above-mentioned prior art, and has a wide variety of layouts depending on the size of the tile, the area of the roof, and the slope of the roof. In consideration of the issues that must be addressed, by setting multiple types of adjustable tiles with different working widths, and by selectively laying adjustable tiles that fit within the range of the remaining eaves length and the crown adjustment width of the crown tiles In order to solve the above-mentioned problem, the necessary corner tiles required for the length of the remaining eaves are laid, and the amount of overlap between the crown tiles and the adjustable corner tiles is appropriately changed so as to secure an appropriate overlap state of the water leakage prevention construction. .

A method of setting a plurality of types of adjustable corner tiles having different working widths is as follows. According to a roof gradient, a width of a cross tile required for a square unit area and the number of working tiles in both directions are determined. Calculate the dimensional difference of the working width of the adjustment corner tiles of each stage from the unadjusted adjustment dimensions of the adjacent tiles at each stage in the flow direction,
The number of adjusting corner tiles is equal to the number of steps in the flow direction of the working width obtained by adding the dimensional difference to the basic dimensions. In addition, the method of selecting roof tiles that fit within the range of the length of the remaining eaves and the crown adjustment width of the roof tiles,
Roof tiles are laid on the roof with the working length required for a square unit area according to the roof slope, and it is compatible with the length of the unfinished remaining eaves adjacent to the tiles, and the crown adjustment width of the crown tiles A roof tile construction method is adopted in which an adjustable corner tile that fits within the range is selected from a plurality of types of adjusted corner tiles and laid, and a roof tile is overlapped with the adjusted corner tile.

(1) As shown in FIG. 1, prior to allocation,
The dimensions and roof slope of the tile 1 whose working length b is adjustable are defined as follows. a: Working width (actual size) (of tile tile 1) b: Working length (actual size) (of tile tile 1) (changeable dimensions are indicated by ± 5 in the figure) K: Slope elongation rate (plan projection by roof slope) This is a constant for calculating the construction dimensions (area) from the above, and is a constant determined by the roof slope.) In the following allocation calculation, the construction area and the actual size of the tile are converted into a plane projection state and calculated. I have.

(2) In the first stage, the allocation is modularized as shown in FIGS. B) Considering the difference between the projected area of the plane and the actual construction area of the sloping roof surface according to the roof slope (gradient elongation K), the working length b of the tile 1 is the actual size (the same as the slope dimension at the time of construction). )), The layout roof is the area (dimensions) of the plane projection, taking into account the difference between the two.) B) The module area Z1 of the specific area in the plane projection state

As shown in FIGS. 2, 3, 4, and 5, the module area Z1 of a specific area and the number of tiles 1 required for the module area are: n1: Number of flow steps (stritching: integer, zigzag: integer) n2 : The number of columns (stritching: integer, zigzag: multiple of 0.5) gives the following relationship. 2 and 4 show the case of the roofing with the Japanese tile, and FIG. 2 (a)
4 shows that the module area Z1 is divided into four rows and three rows (n1 = 4,
FIG. 2 (b) shows an example of the layout in which the tiles 1 are laid with n2 = 3).
3 and 5 show an example of an arrangement of n1 rows and n2 rows. FIGS. 3 and 5 show the case of zigzag roofing with flat tiles. FIGS. 3 (a) and 5 show that the module area Z1 is 3 rows and 2.5 rows (n1 = 3, 3 (b) shows an example of the layout in which the tiles 1 are laid on the cross tile 1 (n2 = 2.5).
An example of column assignment is shown.

Here, considering the actual allocating operation, the constant gradient elongation K is an infinite number below the decimal point, and the working width a and the working length b of the crosspiece 1 are set in 1 mm units around 200 to 300 mm. Since it is difficult to make the above-described relational expression (1) between the module area Z1 and the tile layout with a small module area Z1 and the number of rows n1 and n2 except for a part, In the present invention, the work length b is slightly fluctuable (adjustable), and the tile 1 is formed, and the relational expression (1) is satisfied with a small area and a small number of rows ((a) of FIGS. 2 and 3). And (b)).

On the other hand, when the roof tile 1 is stitched on a roof having a gradient of 6.0 / 10, the working length b is changed. a: Working width (of tile 1) 275 mm b: Working length (of tile 1) 245 ± 5 mm (± 5 mm)

Substituting the dimensions of the tile 1 into the relational expression (1) and calculating the approximate number of rows is as follows.

From this calculation result (2), the number of flow stages n1 =
4. When the number of columns n2 = 3, the module area Z1 is substantially square. Therefore, the working length b (245 ± 5 mm) of the crosspiece 1 when the number of columns is square is calculated by the above-mentioned relational expression (1). ) Is obtained as follows.

Accordingly, the working width a of the cross tile 1 is 275 mm,
A roof tile with a working length b = 245 ± 5 mm and a slope of 6.5 / 10 with a standard working length b = 245 mm, and a roof with a slope of 6.0 / 10 with an adjusted working length b = 240 mm When roofing is applied, the number of flow steps n1 = 4 and the number of columns n2
= 3, the horizontal projection plane of the construction area is a square, and a module area Z1 of a specific small area is set in four steps in the flow direction for three rows in the girder direction. As described above, in the first stage, the width of the roof tiles in both directions necessary for the module area Z1 and the number of flow stages n1 and the number of girder rows n2) and the working length b of the cross tile 1 (standard or adjusted) are determined.

Next, the module area Z in zigzag thatched roof
An example of determining 1, the number of flow steps n1, the number of columns n2, and the working length b of the crosspiece 1 will be described. As an example of an arrangement for satisfying the above-mentioned relational expression (1) with the variable working length b, small area and small number of rows of the cross tile 1, as shown in FIG. 5, a clay tile JIS A5208F type 40 tile (flat tile) Is staggered on a 4.5 / 10 roof. a: Working width (of tile 1) 306 mm b: Working length (of tile 1) 280 ± 5 mm (± 5 mm)

From this calculation result (2), the roof slope 4.5 /
10, when the number of flow stages n1 = 3 and the number of columns n2 = 2.5, the module area Z1 is substantially square. Therefore, the working length b (280 ± 5 mm) of the cross tile 1 is assigned by the reference b = 280 mm.

On the other hand, when the cross tile 1 is staggered on a roof having a gradient of 5.0 / 10, the working length b is changed. a: Working width (of tile 1) 306 mm b: Working length (of tile 1) 280 ± 5 mm (± 5 mm)

Substituting the dimensions of the tile 1 into the relational expression (1) and calculating the approximate number of rows is as follows.

From the calculation result (2), the number of flow stages n1 =
3. When the number of columns is n2 = 2.5, the module area Z1 is substantially square. Therefore, the working length b (280 ± 5 mm) of the cross tile 1 when the number of columns is square is calculated by the above-mentioned relational expression. (1)
Is obtained by substituting into

Therefore, the working width a of the tile 1 is 306 mm,

The horizontal projection plane having a construction area of 2 = 2.5 is a square, and the module area Z1 is set in three steps in the flow direction for 2.5 columns in the girder direction. As described above, in the first stage, the number of tiles (the number of flow steps n1 and the number of girder columns n2) required in the width direction and the direction necessary for the module area Z1 and the working length b (reference or adjusted) of the crosspiece 1 are determined.

(3) In the second stage, corner tiles 3 which are end tiles in modularization are standardized. The reason for determining this standardization (assignment to the unfinished part Z2 on the corner ridge side outside the module area Z1) is as follows. B) As shown in FIG. 5, the module area Z1 is applied to the entire roof, and the shape and size of all the unfinished portions Z2 of a right-angled isosceles triangle in the flow direction on the eaves side and the main building side are the same. It becomes the relationship. (Because the ridge core angle is 45 degrees and the width direction is the same in both directions) b) The maximum adjustment amount in the width direction at each stage of the unfinished part Z2 (adjustment dimension An corresponding to the remaining eave length) The distance between the outer edge of the roof tile 1 or the outer edge of the module area Z1 and the end laying center Y) is less than a predetermined amount based on the working width a of the roof tile 1 (see FIGS. 7 and 8 to 12). (Adjustment dimensions A1,
A2... Exceeds a predetermined amount, that is, the adjustment dimension An
When the measurement position is set to the tail side instead of the head side shown in the figure,
When the working width a is exceeded, one additional tile 1 is allocated, and the center Y of the end laying corresponds to a range of a crown adjustment width B of the crown tile 2 described later. ) C) With the same number of tiles 3a, 3b,... As the number of tiles in the flow direction (number of flow steps n1) determined by the module area Z1, each step end of the unfinished portion Z2 is adjusted and laid, and This is repeated in the unfinished part Z2. D) Adjustable corner tiles 3a, 3b of each step: Adjustment dimension difference An per sheet
_{- 1} -An is determined. E) Several types (same number as the number of flow stages n1) of individual adjustment corner tiles 3a,
3b... Each working width c is determined. F) The working width c of the adjustment corner tiles 3a, 3b,... (The sum of the basic dimension α and the adjustment dimension difference An _{- 1−} An) is determined in consideration of the shape of the adjacent tile 1. (A size that does not cut the adjacent tile 1 is preferable.)

[Results of standardization of end tiles] As shown in FIG. 7, a corner tile unfinished portion Z3 on the left side of the cross tile 1 already laid (assigned) to the module area Z1 and the unfinished portion Z2. ,
Assuming that the adjustment dimensions (distance from the left end of the cross tile 1 to the center Y of the end laying) of each step for laying the corner tile 3 are A1, A2,... For example,
Adjustment dimension difference A1-A2 in the first and second stages),
All of A2-A3,... An _{- 1-} An are as follows (details will be described later). An _{- 1−} An = | ba− The adjustment dimensions A1, A2,... An are added to the basic dimension α in the adjustment corner tiles 3a, 3b, and the working width c is obtained, and the number n1 of flow steps in the module area Z1 is obtained. As many as (n1
= N types) of adjustment corner tiles 3a, 3b ...
The relationship between the plurality of types of adjusting corner tiles 3a, 3b... Is | ba | (ba
(Absolute value). As shown in the comparison between FIG. 7 and FIG. 8, the size and arrangement of the adjusting corner tiles 3a, 3b... In addition to the target (the details will be described later), the same relationship is established between the plurality of unfinished portions Z2 (see FIG. 6).

In the following, the details of the standardization of the adjusting corner tiles 3a, 3b... Of each step will be described. First, as shown in FIG. 8, the case where the upper left corner of the module area Z1 coincides with the center Y of the laying of the end portion. As shown in FIG. 7, when the two do not coincide with each other, it is necessary to change the order of the plurality of types of adjusting corner tiles 3a, 3b. It will be described later. FIG.
The difference between FIG. 8 and FIG. 8 shows that the required adjustment tiles 3a, 3b... Are the same depending on the setting position of the module area Z1, but the arrangement (order) is different, and FIG. And calculation of adjustment corner tiles 3a, 3b ... (calculation of size)
FIG. 8 is a diagram in which the center Y of the end laying and the upper left corner of the module area Z1 are made coincident in order to facilitate
At the bottom corresponds to the one arranged at the fourth stage. On the other hand, FIG. 7 shows that the plurality of types of adjusting corner tiles 3a, 3b... Increase sequentially from the lower side to the upper side with the same difference, and FIGS. 7 and 8 differ from each other except that the position of the module area Z1 is different. Are substantially the same, and the following calculation will be described with reference to FIG.

As shown in FIG. 8, the first area is defined based on the left end of the module area Z1 (the area marked with large diagonal lines in the figure).
The entire length C2 and the width B1 of the unfinished portion Z2 of the right-angled isosceles triangle from the stage (bottom stage) to the n-th stage (top stage) (see the portion with the middle-diagonal hatching in FIG. 6) The entire length of the unfinished part Z2 of the second to n-th stages is C2, the width is B2, and the length of the unfinished part Z2 of the n-th stage (fourth stage in the figure) is Is Cn (C4) and the width is Bn (B4), the center Y of the end laying at the same angle parallel to the ridge in the plane projection state.
Is 45 degrees, the length C and the width B of the entire non-laying portion Z2 of the right-angled isosceles triangle are the same, and C1 = B1, C2 =
B2,..., Cn = Bn (Equation (4)).

Then, as shown in FIG. 9, in the trapezoidal unfinished portion Z2 of the first stage, m tiles 1 (working width a) are located on the left of the module area Z1 (two in the figure). Since the construction can be performed, the adjustment dimension A1 (corresponding to the working width c of the adjustment corner tile 3b) in the unfinished portion Z3 of the first stage tile is A1 = B1
−a × m (formula (5)). Also, as shown in FIG.
In the unfinished portion Z2 of the tier, the module area Z1
Is installed on the left side of (1) (m-1) (one in the figure) one less than the first stage, so that the adjustment dimension A2 of the second stage is A2 = B2-a × ( m-1) (Equation (6)).

Note that the relationship between the number m of laying tiles 1 in the unfinished portion Z2 and the number n of stages of the module area Z1 is the same, ie, m = n-1 in FIG. 7, and m = n in FIG. n-2
It has a relationship. This relationship is when the difference between the number of flow stages n1 and the number of column columns n2 in the module area Z1 is 1, but when the difference between the number of flow stages n1 and the number of column columns n2 is 2 or more, the same relational expression holds. In the results, n1-n2 =
When it is 1, the adjustment corner tiles 3a, 3b,... Are plural types of one pattern, and when n1−n2 = 2, there are two patterns, and this relationship is established sequentially.

The first and second adjustment dimensional differences (A1-
A2) In other words, in order to determine the size of the middle-width adjustment corner tile 3b and the slightly larger adjustment corner tile 3c laid in the first and second stages,
Arrange the variables in equations (5) and (6). As shown in FIG.
The length C2 of the unfinished portion Z2 of the second to n-th stages is
Since the cross tile 1 and the adjusting corner tile 3b (both working length b) are laid on the first stage, the length relationship between the first stage and the second to n-th stages is C2 = C1-b (Equation (7) )), But the unfinished part Z2
Since the relationship of length and width is C1 = B1 and C2 = B2 (Equation (4)), when it is substituted into Equation (7), B2 = B1-b (Equation (8)). , The adjustment dimension A2 of the second stage is A2 = B1-ba- (m-1) (Equation (9)).

The adjustment dimension difference (A1-A2) between the upper and lower adjacent stages of the first stage and the second stage is: Becomes That is, the dimensional difference between the working width c of the intermediate corner adjusting tile 3b and the slightly larger adjusting corner tile 3c in the first stage and the second stage is as follows.
The difference (| ba- |) between the working width a and the working length b of the cross tile 1 is obtained.

Here, comparing the working width a and the working length b of the cross tile 1 in which the dimensional difference of the working width c of the plurality of types of adjusting corner tiles 3a, 3b... Is calculated, the working width a> the working length b (Working width a
A1-A2 = ba (Equation (10))
Is a negative value, and the adjustment dimension A2 of the second step is larger than the adjustment dimension A1 of the first step, that is, the adjustment corner tile 3c of the second step (upper side) is in the first step. It is larger than the eye-adjusting corner tile 3b, and the dimensional difference itself is the absolute value of ba.
−a |.

In the above description, since the relationship between the first stage and the second stage has been described as the upper and lower adjacent stages, the adjustment dimension difference (An _{- 1} -An) of the upper and lower adjacent stages in all stages will be described. That is,
When the above-mentioned relational expressions and calculation formulas (4) to (10) are applied to all stages of the unfinished portion Z2, the following is obtained.

As shown in FIGS. 10 and 11, the second stage and the third stage
The adjustment dimension difference (A2-A3) of the unfinished portion Z3 of the corner tile at the step is as follows. C1 = B1, C2 = B2,..., Cn = Bn (Equation (4)) A2 = B2-a × (m-1) (Equation (5)) A3 = B3-a × (m-2) (Equation 5) (6)) C3 = C2-b (formula (7)) B3 = B2-b (formula (8)) A3 = B2-ba × (m-2) (formula (9)) Therefore, the relationship between the second and third stages is the same as the relationship between the first and second stages.

As shown in FIGS. 11 and 12, the third stage and the fourth stage
The adjustment dimension difference (A3-A4) at the level is as follows. C1 = B1, C2 = B2,..., Cn = Bn (Equation (4)) A3 = B3-a × (m-2) (Equation (5)) A4 = B4-a × (m-3) (Equation 5) (6)) C4 = C3-b (formula (7)) B4 = B3-b (formula (8)) A4 = B3-ba- (m-3) (formula (9)) Accordingly, the third and fourth stages have the same relationship as the first and second stages.

In the calculation of the fourth stage based on FIG. 12, the number of the tiles 1 to be laid on the triangular unfinished portion Z2 is m-3 (-1), and A4 = B4 + a. However, in the illustrated example, the number is m-2 (0),
When determining the working width c of the adjusting corner tile 3a, the working width a of the cross tile 1 is determined.
Needs to be adjusted. In such a case, when determining the adjustment corner tiles 3a, 3b... Based on the final calculation result, the adjustment dimensions A1, A2,.
(As described above, based on the butt side) is not allowed to exceed, that is, when exceeding, the working width a is subtracted. On the other hand, if the above various calculations are performed based on FIG. 7, it is possible to simply set a relation of −1 for the number of laying tiles 1 on the unfinished portion Z2. In the calculation of .about.Cn, B1.about.Bn, etc., it is necessary to add and subtract the upper left margin of the module area Z1 (both length and width).

The adjustment dimension difference between the (n-1) th stage and the nth stage (A
n _{- 1} -An) is as follows, and in the calculation formula,
As described above (see the description of the expression (6) below), m =
n-2. C1 = B1,..., Cn _{− 1} = Bn _{− 1} , Cn = Bn (Equation (4)) An _{− 1} = Bn _{− 1−} a × (n−2) (Equation (5)) An = Bn−a × (n-2-1) (Equation (6)) Cn = Cn _{− 1−} b (Equation (7)) Bn = Bn _{− 1−} b (Equation (8)) An = Bn _{− 1−} b−a × (N-2-1) (Formula (9)) Therefore, the adjustment dimension difference (An _{- 1} -An) between the (n-1) -th stage and the n-th stage in the upper two stages has the same relationship as the first, second, second, third, etc. stages. .

As shown in FIG. 13, 10 rows and 9 rows (n = 1
It will be described that the above equation and the like can be applied to 0). The dimensional difference between the ninth and tenth stages (A9-A1
0) is as follows. C1 = B1, C2 = B2,..., Cn = Bn (Equation (4)) A9 = B9−a × (m−2) (Equation (5)) A10 = B10−a × (m−2-1) (Equation (6)) C10 = C9-b (Equation (7)) B10 = B9-b (Equation (8)) A10 = B9-ba × (m-2-1) (Equation (9)) Therefore, the relations of the ninth and tenth stages also correspond to the first, second, and nth stages.
-1, the same relationship as the n-th stage, etc.

Therefore, the adjustments in the upper and lower adjacent stages are determined by the relationship between the first stage and the second stage, the second stage and the third stage, and the (n-1) th stage and the nth stage. Dimensional difference An _{- 1-} An
Since the relationship of = ba is established in all the adjustment corner tiles 3a, 3b,... And the working width a> the working length b, ba is a negative value and the upper adjustment corner tile is 3a, 3b ... increase.

As shown in FIG. 8, in the first, second, and third stages, the difference between the adjustment dimensions A1, A2, and A3 (the working width of the adjustment corner tiles 3a, 3b...) Is | ba- | At the same time, it has been described that the size of the upper stage is larger. In the third stage and the fourth stage, the size difference is | ba |, but the upper stage is smaller. The reason for this is that, as described in the section, in the first, second, third, and fourth stages, the cross tile 1 is laid in the trapezoidal unfinished portion Z2 of each stage, ie, Third
Since the cross tile 1 is not laid at the level and the -1 piece is laid at the fourth level, the working width a is subtracted as the final result of the adjustment corner tiles 3a, 3b. B4 +
This is equivalent to replacing part of a with the roof tile 1. On the other hand, the one shown in FIG. 7 corresponds to the one in which the fourth stage in FIG. 8 is arranged at the lowermost stage, and the lower the upper stage, the lower the adjustment corner tiles 3a, 3b.
... are increased by | b-a |, and when the adjustment dimension An exceeds the working width a, the working width a of the cross tile 1 is subtracted, and this is repeated. The difference between the two is the set position of the module area Z1. caused by.

As is apparent from the above results, the adjustment corner tile 3
a, 3b... have the same number of types as the number n1 of flow steps of the module area Z1, and in the case of the roofing, individual adjustment corner tiles 3a, 3b.
Is | ba |, and a plurality of types of adjusting corner tiles
The same relationship is established in a plurality of unlaid portions Z2 where 3a, 3b,... Are laid.

Next, the working width c of the individual adjusting corner tiles 3a, 3b...
Will be described. As shown in FIG. 14, the size (working width c) of the adjusting corner tiles 3a, 3b,... Laid on the unfinished corner tiles Z3 of each stage is the working width of the minimum width adjusting corner tile 3a. To c
(Basic dimension is α) Adjusting corner tiles 3b, 3c for middle width etc.
... is the difference between the basic dimension α (working width c) and the adjustment dimension | ba−
Are sequentially added and become larger.

Incidentally, the working width c of the minimum width adjustment corner tile 3a
As a criterion for the determination, the size that does not cut the adjacent roof tile 1 is preferable. If the working length b of the roof tile 1 is employed as the dimension of the working width c of the adjusting corner tile 3a as shown in FIG. The tile 1 does not need to be cut, and as shown in FIG. 15 (b), it is possible to make the working width c ′ larger than the working length b. Is preferably equal to or more than the working length b of the tile 1. On the other hand, if a larger dimension is adopted as the basic dimension α of the minimum width adjustment corner tile 3a,
The size of the adjustment corner tile 3n having the maximum width is α + n × | ba−, and it is expected that the adjustment corner tile 3n will be too large and difficult to manufacture. On the other hand, as shown in FIG. 15 (c), if the dimension of the working width c ″ of the minimum width adjusting corner tile 3a is smaller than the working length b of the roof tile 1, the adjacent roof tile 1 needs to be cut. Occurs.

The working width c of the adjusting corner tiles 3a, 3b,... Is summarized as follows.
The adjustment tiles 3b, 3c,... Of the other widths are obtained by adding the adjustment dimension difference An _{- 1−} An to the basic dimension α.
, And the total number of the corner tiles 3a, 3b,... Is equal to the number n1 of flow steps. In the case shown in FIG. 14, the one having the basic dimension α is the first kind of adjusting corner tile 3a, the one having the basic dimension α plus the dimensional difference An _{- 1−} An is the second kind of adjusting corner tile 3b,
The third kind of adjusting corner tile 3c is different from the second kind of adjusting corner tile 3b by a dimensional difference An.
_{- 1} -An obtained by adding the, in other words the three adjustment Sumikawara 3c are two dimensional difference An in basic dimensions alpha _- means that by integrating ₁ -An, similarly, of the n or fewer The adjustment corner tile 3n is obtained by integrating n-1 dimensional differences An _{- 1} -An with the basic dimension α.

As described above, the method of calculating the individual adjustment corner tiles 3a, 3b,... And the preferred dimensions have been described. Next, when the module area Z1 is set, the Japanese tile (cross tile 1) shown in FIG. FIG. 16 shows an example of preferable dimensions of the adjusting corner tiles 3a, 3b,. FIG. 16 (a) shows an example of laying with a roof slope of 6.5 / 10, and FIG. 16 (b) shows a roof slope of 6.0 / with respect to the tile 1 having a working width a = 275 mm and a working length b = 245 ± 5 mm.
In the ten laying examples, when the roof gradient is 6.5 / 10, the working width a of the minimum width adjusting tile 3a is 245 mm, the difference is 30 mm in order, and the maximum width adjusting corner tile 3d is 335 mm. In the case of 6.0 / 10, the adjustment corner tiles 3a to 3d have a working width of 240 to 315 mm with a difference of 35 mm.

When the above results are summarized, the working width a
= 275 mm, working length b = 245 ± 5 mm, when working with the Japanese type tile 1, the working width a is 245 mm, 275 mm, 305 mm, 3 for laying on the roof gradient 6.5 / 10.
If the four kinds of adjustable corner tiles 3a, 3b... Of 35 mm are manufactured, it is not necessary to cut the cross tile 1 and the adjustable corner tiles 3a, 3b. ~ 31
If the four types of 5 mm adjusted corner tiles 3 a, 3 b, etc. are manufactured, cutting is also unnecessary, and for one type of cross tile 1, one set of adjusted corner tiles 3 a, 3 b. Is prepared, the adjustment corner tiles 3a, 3b ... need not be cut.

Next, a description will be given of the case of the staggered roofing, but a part of the portion common to the staggered roofing is omitted. FIG.
As shown in FIG. 18, when the unfinished part Z2 is set with reference to the left end of the module area Z1 (the part with a large diagonal line in the figure), a part of the unlaid part Z2 has the module area Z1. Although there is a part of the allocated tile 1 (the second broken line in FIGS. 3 and 5), the calculation is performed with priority given to the module area Z1. Similarly to the case of the roofing, the entire length of the unfinished portion Z2 of the right-angled isosceles triangle from the first stage (lowest stage) to the n-th stage (top stage) is C1, the width is B1, The entire length of the unfinished portion Z2 of the second to nth stages is C2, the width is B2, and the length of the unfinished portion Z2 of the nth stage (third stage in the figure) is Cn ( C3), assuming that the width is Bn (B3), the laying center Y of the end portion is 45 degrees in a plane projection state, and thus the entire length C2 of the unfinished portion Z2 of the right-angled isosceles triangle.
, C1 = B1, C2 = B2,..., C
n = Bn (Equation (4)).

Then, as shown in FIG. 19, in the unfinished portion Z2 of the first trapezoidal shape, the module area Z1
M tiles (working width a) can be constructed m sheets (one sheet in the figure) on the left side of the above, so the adjustment dimension A1 by the adjustment corner tiles 3a, 3b ...
A1 = B1−a × m (Equation (5)). In addition, as shown in FIG. 20, in the second-stage unfinished portion Z2, the cross tile 1 is constructed at a position that straddles both the module area Z1 and the unfinished portion Z2. It is equivalent to half the construction in place of one of the tiles 1 and the number (m-1 / 2) less than the first stage (m-1 / 2) on the left of the module area Z1 ( 1/2 of the left half of the tile)
Therefore, the adjustment dimension A2 is A2 = B2-a ×
(M-1 / 2) (Equation (6)). Note that the relationship between the number m of laying tiles 1 and the number n of steps of the module area Z1 in the unfinished portion is the same difference, and m = n−2 in FIG. 19 and m = n−2 in FIG. 1/2 (this 1/2 is 1/2 x
(N-1) (n is the n-th stage).

The adjustment dimension difference (A1-
A2) In other words, in order to obtain the sizes of the adjustment corner tiles 3a and 3b laid in the first and second stages, the variables of the equations (5) and (6) are arranged. As shown in FIG. 20, the length C2 of the unfinished portion Z2 of the second to n-th stages is determined by
And the roof tile 3 (both working length b) is laid,
The length relationship between the stage and the second to n-th stages is C2 = C1-b (formula
(7)), while the length-width relationship of the unfinished portion Z2 is C1.
= B1 and C2 = B2 (Equation (4)). Therefore, substituting into Equation (7) gives B2 = B1-b (Equation (8)).
, The adjustment dimension A2 of the second stage is A2 = B1
−b−a × (m− ／) (Equation (9)).

The adjustment dimension difference (A1-A2) between the upper and lower adjacent stages of the first stage and the second stage is: Becomes That is, the adjustment corner tile 3 in the first stage and the second stage
The dimensional difference between a, 3b,... is (| ba−2 |) obtained from the working width a and the working length b.

Here, comparing the working width a and the working length b of the cross tile 1 in which the dimensional difference between the plurality of types of adjusting corner tiles 3a, 3b... Is calculated, the working width a> the working length b (the working width) (the value of a is large), A1-A2 = ba-2 (Equation (10)) is usually a positive value, and the adjustment dimension A2 of the second stage is smaller than the adjustment dimension A1 of the first stage. This means that the second corner (upper side) of the adjustment corner tile 3b is smaller. However, as shown in FIG. 22, the upper part may be large depending on the position of the module area Z1, and the dimensional difference itself is the absolute value of ba−2 as in the case of the roofing. a / 2 |. This is caused by the module area Z
This is because the number of the tiles 1 to be laid in the unfinished portion Z2 is different due to the difference in position 1 in order to solve this. The steps may be calculated, and the calculation result of the first step may be calculated in consideration of the additional setting of one tile 1.

In the above description, the relationship between the first stage and the second stage has been described as the upper and lower adjacent stages, so the adjustment dimension difference (An _{- 1} -An) of the upper and lower adjacent stages in all stages will be described. That is,
When the above-mentioned relational expressions and calculation formulas (4) to (10) are applied to all stages of the unfinished portion Z2, the following is obtained.

As shown in FIGS. 20 and 21, the second stage and the third stage
The adjustment dimension difference (A2-A3) at the level is as follows. C1 = B1, C2 = B2,..., Cn = Bn (Equation (4)) A2 = B2-a × (m−1 / 2) (Equation (5)) A3 = B3-a × (m−1 / 2 × 2) (Formula (6)) C3 = C2-b (Formula (7)) B3 = B2-b (Formula (8)) A3 = B2-ba × (m-1) (Formula (9) ) Therefore, the relationship between the second and third stages is the same as the relationship between the first and second stages.

The adjustment dimension difference between the (n−1) th stage and the nth stage (A
n _{- 1} -An) is as follows, and in the calculation formula,
As described above (see the description of the expression (6) below), m =
n-2-1 / 2 (n-1). C1 = B1,..., Cn _{- 1} = Bn _{- 1} , Cn = Bn (Equation (4)) An _{- 1} = Bn- _1- a * (n-2-1 / 2 (n-1)) (Equation 4) (5)) An = Bn−a × (n−2-1 / 2 (n−1)) (formula (6)) Cn = Cn _{− 1−} b (formula (7)) Bn = Bn _{− 1−} b (Equation (8)) An = Bn _{− 1} −ba− (n−2-1 / 2 (n−1)) (Equation (9)) An _{− 1−} An = (Bn _{− 1−} a × ( (n-2-1 / 2 (n-1)))-(Bn- ₁ -ba- (n-2-1 / 2 (n-1))) (Equation (5))-(Equation (9) )) = B−a / 2 (Equation (10)) Accordingly, the adjustment dimension difference (An _{− 1−} An) of the (n−1) th stage and the nth stage of the upper two stages is the first and second stages. It has the same relationship as the eye, the second and third stages, etc.

Therefore, the adjustment in the upper and lower adjacent stages is determined as determined by the relationship between the first stage and the second stage, the second stage and the third stage, and the (n−1) th stage and the nth stage. Dimensional difference An- _1- An
= Ba / 2 holds for all the stages of the adjusting corner tiles 3a, 3b.

As is clear from the above results, the adjustment corner tile 3
a, 3b... have the same number of types as the number of flow stages n1 of the module area Z1, and in the case of a staggered roof, individual adjustment corner tiles 3a, 3b
Are the same as | b−a / 2 |, and a plurality of unfinished portions Z for laying a plurality of types of adjusting corner tiles 3a, 3b.
2 establishes the same relationship.

Next, the working width c of the individual adjusting corner tiles 3a, 3b.
Will be described. FIG.
As shown in FIG. 3, the size (working width c) of the adjusting corner tiles 3a, 3b,... Laid in the unfinished corner tiles Z3 of each stage is determined by the working width of the minimum width adjusting corner tile 3c. Assuming that a certain working width is c (the basic dimension is α), the adjusted corner tiles 3a, 3b... Of the intermediate width and the like sequentially add the adjusted dimension difference | ba−2 | to the basic dimension α (working width c). Being bigger. And the minimum width adjustment corner tile
The working width c of 3c is the same as in the case of the roofing,
Is preferable, and the working length b of the tile 1 is
The above is preferable (see FIG. 15 and its description).

The working width c of the adjusting corner tiles 3a, 3b,... Is summarized as follows.
The adjustment corner tiles 3a, 3b of the other widths are obtained by adding the adjustment dimension difference An _{- 1−} An to the basic dimension α.
, And the total number of the corner tiles 3a, 3b,... Is equal to the number n1 of flow steps. In the case shown in FIG. 23, the one having the basic dimension α is the first kind of adjustment corner tile 3c, the one having the dimension difference An _{- 1−} An added to the basic dimension α is the second kind of adjustment corner tile 3b,
The third type adjustment corner tile 3a is different from the second type adjustment corner tile 3b by the dimensional difference An.
_{- 1} -An obtained by adding the, in other words the three adjustment Sumikawara 3a is two dimensional difference An in basic dimensions alpha _- means that by integrating ₁ -An, similarly, of the n or fewer The adjustment corner tile 3n is obtained by integrating n-1 dimensional differences An _{- 1} -An with the basic dimension α.

As described above, the method of calculating the individual adjustment corner tiles 3a, 3b,... And the preferred dimensions have been described. Next, when setting the module area Z1, the case of the flat roof tile (cross tile 1) with reference to FIG. FIG. 24 shows a preferred dimension example of the adjustment corner tiles 3a, 3b,. FIG. 24 (a) shows an example of laying with a roof slope of 4.5 / 10, and FIG. 24 (b) shows a roof slope of 5.0 / with respect to the tile 1 having a working width a = 306 mm and a working length b = 280 ± 5 mm.
In the ten laying examples, when the roof slope is 4.5 / 10, the working width a of the minimum width adjusting corner tile 3c is 280 mm, and the difference is 127 mm in order, and the maximum width adjusting corner tile 3a is 534 mm. In the case of 5.0 / 10, the adjustment corner tiles 3a to 3c are 132 mm.
Is a working width of 285 to 549 mm.

When the above results are summarized, the working width a
= 306 mm, working length b = 280 ± 5 mm When working with flat tile 1, the working width a is 280 mm, 407 mm, and 534 mm for laying on a roof gradient of 4.5 / 10.
If the kinds of adjusting corner tiles 3a, 3b... Are manufactured, cutting becomes unnecessary, and the same flat plate tile 1 is used for roof gradient 5.0 / 10 for 28/10.
If three types of adjustable corner tiles 3a, 3b... Of 5 to 549 mm are manufactured, no cutting is required, and one type of tile tiles 1 is provided with a plurality of types of adjusted corner tiles 3a, 3b. Is prepared, the adjustment corner tiles 3a, 3b ... need not be cut.

The method of determining the adjusted corner tiles 3a, 3b... Based on the individual unfinished corner tiles Z3 is as described above, but FIG. 8 of stitched roof and FIG. 7 of staggered roof both show the module area Z1.
Is the case where the upper left corner coincides with the ridgeline Y. Next, the case where they do not coincide with each other as shown in FIG. As a result, it is not necessary to determine the size of the adjustment tiles 3a, 3b, etc., assuming that they do not match at the time of construction. .. Correspond to each other.
