Hereinafter, this embodiment will be described in detail using the drawings.
1 to 9 are for explaining this embodiment.

<Structure> The structure of this embodiment will be explained below.

As shown in FIG. 1, a building 1 such as a house is renovated, and a siding panel 3 (FIG. 3) is attached to the outside of the existing outer wall 2 (FIG. 2) of the building 1.

Here, the building 1 may be of any type, but is preferably, for example, a unit building. The unit building is a building 1 that can be constructed in a short period of time by transporting building units manufactured in advance at a factory to a construction site and assembling them at the construction site.

The outer wall 2 is a wall that constitutes the outer surface of the building 1. The outer wall 2 is constructed by attaching an outer wall panel to the outer surface of the building 1 when the building 1 is newly constructed. There are various types of exterior wall panels, such as vertically long panels and horizontally long panels.

In this embodiment, the siding panel 3 is a panel for renovation that is installed overlappingly on the outside of the existing outer wall 2 of the building 1 during renovation. In the case of this embodiment, the siding panels 3 for renovation are horizontally long panels, and are installed horizontally on the building 1 so as to be stacked from bottom to top. The siding panels 3 for renovation are used by cutting standard dimensions to fit the building 1. There are a plurality of standard sizes of siding panels 3 for renovation.

The siding panel 3 has, for example, a tongue-shaped structure having a fitting convex portion 4 on the upper edge and a fitting recess 5 on the lower edge, and the fitting convex portion 4 has a fitting concave portion. It is designed to be added in the vertical direction 6 while fitting the parts 5 together.

The siding panel 3 is attached from the outside with fixing tools 8 such as screws to a rim 7 (vertical rim) extending in a vertical direction 6 that is installed on the surface of an existing outer wall 2 of a building 1 for renovation purposes. The upper part of the siding panel 3 may have an attachment part 9 for attachment to the furring 7. The attachment portion 9 is fixed to the furring 7 using a fixing device 8 such as a screw.

A starter fitting 11 is installed at the lower end of the rim 7 to define a starting position for installing the siding panel 3. Furthermore, a parting fitting 12 is installed at the upper end of the furring 7 to define the end position of the siding panel 3. The starter metal fitting 11 has a convex portion that fits into the fitting recess 5 of the siding panel 3 located at the lowest position from below. In addition, since it is desirable to install the siding panel 3 so that the existing outer wall 2 is completely hidden from view from the outside, the position of the lower part of the siding panel 3 installed at the lowest part is the same as the lowermost part of the existing outer wall 2. It is set to be slightly lower than the position. The parting metal fitting 12 is designed to wrap around the upper edge of the siding panel 3 located at the top from above.

Since it is a difficult task to cut each siding panel 3 to fit the shape of the installation location at the renovation site, most of the siding panels 3 used for renovation are pre-cut at a factory to fit the building 1. At a renovation site, it is desired to be able to simply attach the precut siding panel 3 to the rim 7 as is. For this purpose, the siding panel precut support system 15 of this embodiment is provided.

Note that precutting means cutting the siding panel 3 in advance at a factory to fit the installation location of the building 1.

The siding panel precut support system 15 of this embodiment can have the following configuration.

(1) As shown in FIG. 4, the siding panel pre-cut support system 15 determines pre-cut dimensions for pre-cutting the siding panel 3 to be installed on the outside of the existing exterior wall 2 of the building 1 to a size that matches the building 1. A precut dimension calculation section 16 is provided.
The pre-cut dimension calculation unit 16 includes an under-eave panel pre-cut dimension calculation unit 22 that calculates the pre-cut height 21 of the siding panel 3 (for example, East-5 to East-9 in FIG. 1) installed at the top of the building 1. Do it like this.

Here, the siding panel pre-cut support system 15 is a device for supporting pre-cutting of the siding panels 3 used in the renovation of the building 1 at a factory. The siding panel pre-cut support system 15 creates processing data used to pre-cut the siding panel 3 with a siding processing device installed in a factory.

The pre-cut dimensions are dimensions for pre-cutting the siding panel 3. The precut dimensions include a width dimension and a height dimension.

The precut dimension calculation unit 16 constitutes the main part of the siding panel precut support system 15, and mainly calculates the precut dimension (precut height 21) of the siding panel 3 in the height direction (vertical direction 6). The precut dimension calculation unit 16 is configured by an arithmetic and control device 23 such as a computer, software installed in the arithmetic and control device 23, and the like. The pre-cut dimension calculation unit 16 uses, for example, an arithmetic and control device 23 such as a computer installed with a system (siding panel development system 25) for developing parts of the siding panel 3 to be attached to the existing exterior wall 2 of the building 1 to be renovated. It is preferable to configure it as follows.

The siding panel deployment system 25 described above includes at least an information input section 26 (or a building information input section) and a layout setting section 27. The information input unit 26 is a functional part that inputs various information regarding the building 1 such as the shape of the building 1 and the position of the opening 28 of the building 1. The information input unit 26 may directly input information about the building 1 manually, or may take in and use external information. The external information can be, for example, data such as a database of a construction company. The database of the construction company accumulates various data regarding the building 1. If possible, it is preferable to acquire the necessary data from the construction company's database via a network, but it is also possible to acquire the necessary data via a storage medium or the like.

For example, the layout setting unit 27 sets (or determines) the layout in the width direction 31 of the siding panel 3 based on the position 29 of the side part of the opening 28 of the building 1, and selects the siding to be used based on the set layout. Expand panel 3 into parts.

The opening 28 is a penetrating portion formed in the outer wall 2 of the building 1 that penetrates between the indoor and outdoor areas. A window 28a, a door 28b, and the like are installed in the opening 28. For example, in the case of the building 1 such as a unit building, the position and size of the opening 28 are standardized to some extent, so by using the position 29 of the side of the opening 28 as a reference, the width of the siding panel 3 can be adjusted. It can be successfully allocated to direction 31.

Note that if the openings 28 are installed on the upper and lower floors of the building 1 so that their positions overlap in the vertical direction 6, the position 29 on the side of either opening 28 is It is desirable to use it as a standard. For example, since the upper floors of the building 1 often have a simpler shape, the layout can be relatively easily done using the side position 29 of the opening 28 on the upper floor as a reference. The opening 28 and its side position 29 to be used as a reference may be selected by the operator of the siding panel expansion system 25 (or the siding panel pre-cut support system 15), or may be selected automatically by setting conditions. It may be possible to do so.

For example, FIG. 1 shows an example of the allocation of siding panels 3 to an outer wall 2 located on the east side of a building 1. In the outer wall 2 on the east side of the building 1, one window 28a is installed on the left side of the lower floor part, and one door 28b is installed in the center. Furthermore, two windows 28a (Yoko-daka windows (Yo-daka I and Yo-daka J)) are installed on the left and right sides of the upper floor. On the left side of the outer wall 2 on the east side, the windows 28a of the upper and lower floors partially overlap vertically. Further, regarding the door 28b and the right window 28a (Yoko J), there is no vertical overlap. In such a situation, for example, the siding panel 3 can be divided in the width direction 31 by using the position 29 of the inside side of the two windows 28a on the upper floor (Yoko I and Yoko J) as a reference. Can be attached.

In this case, the specific layout of the siding panels 3 in the width direction 31 by the layout setting unit 27 is, for example, in order from the right side to the left side: a corner siding panel 3 (corner RD), a siding panel 3 with a width of 1791 mm ( 1791), 666mm wide siding panel 3 (666), 1791mm wide siding panel 3 (1791), 666mm wide siding panel 3 (666), 1791mm wide siding panel 3 (1791), corner siding panel 3 ( Corner RD) etc.

Then, the layout setting unit 27 first applies the above-described layout for the width direction 31 of the siding panel 3 to the vertical direction 6 as well. As a result, rows 32 to 38 of siding panels 3 in the vertical direction 6 are formed on the outer wall 2 located on the east side of the building 1, and a basic allocation of the siding panels 3 to the outer wall 2 of the building 1 is obtained.

Next, the basic layout of the siding panels 3 described above is modified according to the condition of the outer wall 2 of the building 1. This basic layout can be modified manually by the operator using the layout setting section 27, or can be automatically made by the layout setting section 27.

First, the siding panel 3 at the location of the opening 28 is partially changed in accordance with the width dimension of the opening 28. For example, at a position overlapping the window 28a, the siding panel 3 with a width of 1791 mm set by the basic layout is changed to a siding panel 3 (891) with a width of 891 mm so as to have the width excluding the window 28a. In addition, at the position overlapping with the door 28b, the siding panel 3 with a width of 1791 mm set by the basic layout is replaced with two siding panels 3 (441) with a width of 441 mm so that the width dimension excludes the door 28b. These are changed so that they are arranged on both sides of the door 28b. Thereby, a space for the opening 28 is secured in the outer wall 2 of the building 1.

Furthermore, for example, the vertical layout 6 of the siding panels 3 located above and below the opening 28 is partially changed. That is, the siding panel 3 (for example, FIG. 3) having a normal standard height is replaced with a siding panel 3 (891-4, 1791-4, 666-4, etc.) having a smaller height dimension (FIG. 5). A siding panel 3 with a suffix (-4) indicates a siding panel 3 that is smaller in height than a standard siding panel 3. Siding panels 3 with (-4) at the end are standardized products with a height that is 2/3 of the standard height siding panel 3 without (-4) at the end. . Therefore, it is possible to replace the two upper and lower standard siding panels 3 with three upper and lower siding panels 3 having smaller height dimensions.

In this embodiment, at least the lower side of the opening 28 is replaced with the siding panel 3 having a smaller height dimension. Further, above the opening 28 on the upper floor, the two upper and lower siding panels 3 are made into siding panels 3 with a smaller height dimension. The installation of the siding panel 3 having a small height above the opening 28 is carried out by comprehensively considering the height of the building 1, the position and height of the window 28a, etc. These siding panels 3 can be replaced manually or automatically.

In this way, after the basic layout of the siding panels 3 and the corrections to the basic layout as described above are completed, the layout setting section 27 creates layout information and performs the layout based on this layout information. Part number and quantity information is created by developing the siding panel 3 into part numbers and quantities. By using this product number/quantity information, the siding panel 3 is precut at the factory to a width dimension according to the layout in the layout setting section 27 and shipped to the renovation site. Note that this layout of the siding panels 3 is merely an example, and is not limited to the above.

Then, the width dimension of the siding panel 3 is pre-cut according to this layout, but if the siding panel 3 is only pre-cut in the width direction 31, the siding panel 3 will have to be cut in the height dimension at the renovation site. Many will occur. For example, the height of the existing exterior wall 2 is determined at the time of construction, regardless of the standard height of the siding panel 3. Dimensions will need to be adjusted. Therefore, it is necessary to cut the height of the uppermost siding panel 3 (East-5 to East-9) to match the height of the outer wall 2. In addition, for example, the opening 28 ( Since there is interference with the window 28a), it is necessary to cut the interfering part.

Therefore, in this embodiment, a pre-cut dimension calculating section 16 is provided so that the above-described siding panel 3 can be pre-cut with respect to the height dimension.

The pre-cut dimension calculating section 16 extracts the siding panels 3 whose height dimension requires pre-cutting from among the siding panels 3 assigned by the layout setting section 27, and calculates the pre-cut height 21 (pre-cut dimension) of the extracted siding panel 3. ). Siding panels 3 that require pre-cutting of height dimensions (for example, the top siding panel 3 or the siding panel 3 that interferes with the opening 28 as described above) can be extracted by directly specifying them by the operator. It may be possible to extract the information automatically, or it may be possible to extract it automatically.

After calculating the precut dimensions, the precut dimension calculation unit 16 creates precut product number/quantity information. Then, necessary portions of the product number and quantity information created by the allocation setting unit 27 are corrected based on the precut product number and quantity information obtained by the precut dimension calculation unit 16. This makes it possible to pre-cut the height of the siding panel 3. Corrections to the pre-cut product number and quantity information may be made manually by the operator, or may be made automatically.

Furthermore, the siding panel development system 25 and the siding panel pre-cut support system 15 create packaging labels for the siding panels 3 that have been pre-cut in the width direction 31 and height direction (label creation section), and pre-cut the siding panels 3. It is also possible to create production instruction data and production instruction sheets (production instruction data creation department).

At the factory, upon receiving this production instruction data and production instructions, the siding processing equipment processes the siding panels 3 in the width direction 31 and height direction based on the production instruction data and production instructions. The pre-cut siding panels 3 are packaged using a packaging device, a packaging label printed using a label printing device is attached, and the siding panels 3 are shipped to a renovation site.

The under-eave panel pre-cut dimension calculation unit 22 is a functional part provided inside the pre-cut dimension calculation unit 16, and has a function of calculating the pre-cut height 21 of the uppermost siding panel 3.

The siding panel 3 installed at the top is the siding panel 3 (under-eaves panel) pasted at the top (under the eaves) of the building 1. Since the siding panels 3 are pasted in order from the bottom to the top, the uppermost siding panel 3 is the one that is pasted last. Therefore, by only pre-cutting the height of the siding panel 3 installed at the top, the siding panels 3 below can be used as they are at the standard height. In this example, as described above, the siding panels 3 installed at the top are (East-5 to East-9).

The precut height 21 is the height dimension of the component after the siding panel 3 is precut at a factory.

(2) The under-eave panel pre-cut dimension calculation unit 22 calculates the distance from the lower position 41 of the siding panel 3 (East-5 to East-9) installed at the top to the upper position 42 of the outer wall 2. , the pre-cut height 21 of the uppermost siding panel 3 may be used.

Here, the lower position 41 of the siding panel 3 installed at the top is the total height of all the siding panels 3 installed below the siding panel 3 installed at the top. The position 41 of the lower part of the siding panel 3 installed at the top can be obtained from the layout set by the layout setting section 27. In other words, all of the siding panels 3 installed below the top siding panel 3 remain at the standard height, so the value is calculated by multiplying the number of siding panels 3 by the standard height. is the lower position 41 of the siding panel 3 installed at the top. If siding panels 3 of different standard heights are mixed, the values obtained by multiplying the number of panels by each standard height may be summed.

The position 42 of the top of the outer wall 2 is the height from the bottom to the top of the outer wall 2, and a known value obtained by the information input unit 26 can be used.

The distance from the bottom position 41 of the siding panel 3 installed at the top to the top position 42 of the exterior wall 2 is calculated by subtracting the bottom of the siding panel 3 installed at the top from the top position 42 of the exterior wall 2. You can get it at

The precut height 21 of the uppermost siding panel 3 is the height dimension of the remaining lower part after the upper part of the uppermost siding panel 3 is precut in the height direction.

In addition, if all siding panels 3 have the same standard height, the pre-cut height 21 of the uppermost siding panel 3 is calculated as the remainder after dividing the height of the outer wall 2 by the standard height of the siding panel 3. It is also possible to calculate

(3) The precut dimension calculation unit 16 includes an opening panel precut dimension calculation unit 51 that calculates the precut height 21 of the siding panels 3 (East-1 to East-4) installed above and below the opening 28 of the building 1. It's good to be prepared.

Here, in the building 1, the size and installation position of the openings 28 such as the windows 28a and the doors 28b are determined at the time of construction, regardless of the standard height of the siding panel 3. A situation occurs in which the siding panel 3 cannot be installed properly in some areas. Further, even if the specifications of openings 28 such as windows 28a and doors 28b are changed during renovation, this situation remains. Therefore, it is necessary to be able to adjust the height dimensions of at least the siding panels 3 installed above and below the opening 28.

The siding panels 3 installed above and below the opening 28 of the building 1 refer to the siding panel 3 installed above the opening 28 and the siding panel 3 installed below the opening 28.

The pre-cut height 21 is the height dimension of the remaining lower part after pre-cutting the height of (at least a part of) the upper part of the siding panel 3 below the opening 28 to match the lower part of the opening 28. It is about. Moreover, the pre-cut height 21 is the height dimension of the remaining upper part after pre-cutting the height of (at least a part of) the lower part of the siding panel 3 above the opening 28 to the upper part of the opening 28. It is about.

The opening panel pre-cut dimension calculation unit 51 is a functional part provided inside the pre-cut dimension calculation unit 16, and calculates the pre-cut height of (at least one or both of) the siding panels 3 installed above and below the opening 28. It has a function to calculate 21.

Below, the two windows 28a (East-1 to East-4) on the upper floor, which were used as standards when allocating the siding panels 3 in the width direction 31, are used as examples of the openings 28, and the windows 28a are installed above and below the openings 28. A method of calculating the precut height 21 of the siding panel 3 by the opening panel precut dimension calculation unit 51 will be explained.

(4) The opening panel pre-cut dimension calculation unit 51 calculates the range from the lower position 52 of the siding panel 3 (East-1, East-3) installed directly below the opening 28 to the lower position 53 of the opening 28. The pre-cut height 21 of the siding panel 3 installed directly below the opening 28 may be determined by determining the distance.
Furthermore, the opening panel pre-cut dimension calculation unit 51 calculates the range from the upper position 54 of the opening 28 to the upper position 55 of the siding panel 3 (East-2, East-4) installed directly above the opening 28. The pre-cut height 21 of the siding panel 3 installed directly above the opening 28 may be determined by determining the distance.

Here, the siding panel 3 installed directly below the opening 28 is one siding panel 3 pasted directly below the opening 28.

The lower position 52 of the siding panel 3 installed directly below the opening 28 is the total height of all the siding panels 3 installed below the siding panel 3 installed directly below the opening 28. The position 52 of the lower part of the siding panel 3 installed directly below the opening 28 can be obtained from the layout set in the layout setting section 27. In other words, all of the siding panels 3 installed below the siding panel 3 installed directly below the opening 28 remain at the standard height, so the standard height is adjusted to the number of siding panels 3. The multiplied value becomes the lower position 52 of the siding panel 3 installed directly below the opening 28. If siding panels 3 of different standard heights are mixed, the values obtained by multiplying the number of panels by each standard height may be summed.

The lower position 53 of the opening 28 is the height from the lower part of the outer wall 2 to the lower edge of the opening 28, and a known value obtained by the information input unit 26 can be used.

The distance from the lower position 52 of the siding panel 3 installed directly below the opening 28 to the lower position 53 of the opening 28 is the distance from the lower position 53 of the opening 28 to the lower position 53 of the siding panel 3 installed directly below the opening 28 It can be obtained by subtracting the position 52 of the lower part of the siding panel 3.

The precut height 21 of the siding panel 3 installed directly below the opening 28 is the height of the remaining lower part after the upper part of the siding panel 3 installed directly below the opening 28 is precut in the height direction. It refers to the size. In this embodiment, the siding panel 3 (1791-4) installed directly below the opening 28 is pre-cut into a stepped shape with a partially cut out upper part (having a cutout 56) as shown in FIG. It is processed to become (East-1). For (East-3), the pre-cut height 21 is found in the same manner as above.

In addition, if all siding panels 3 have the same standard height, the height of the lower part of the opening 28 is divided by the standard height of the siding panel 3, and the siding panel directly below the opening 28 is calculated as the remainder. It is also possible to calculate the precut height 21 of 3.

Further, the upper position 54 of the opening 28 is the height from the lower part of the outer wall 2 to the upper edge of the opening 28, and a known value obtained by the information input unit 26 can be used. .

The siding panel 3 installed right above the opening 28 is a single siding panel 3 that is pasted right above the opening 28.

The upper position 55 of the siding panel 3 installed directly above the opening 28 is the sum of the siding panel 3 installed directly above the opening 28 and all the siding panels 3 installed below it. The height will be . The position 55 of the upper part of the siding panel 3 installed directly above the opening 28 can be obtained from the layout set in the layout setting section 27. In other words, the siding panel 3 installed directly above the opening 28 and all the siding panels 3 installed below it remain at the standard height, so the number of siding panels 3 does not conform to the standard height. The value multiplied by the height becomes the upper position 55 of the siding panel 3 installed directly above the opening 28. If siding panels 3 of different standard heights are mixed, the values obtained by multiplying the number of panels by each standard height may be summed.

The distance from the top position 54 of the opening 28 to the top position 55 of the siding panel 3 installed directly above the opening 28 is the distance from the top position 54 of the opening 28 to the top position 55 of the siding panel 3 installed directly above the opening 28. It can be obtained by subtracting the position 54 of the top of the opening 28 from 55.

The pre-cut height 21 of the siding panel 3 installed directly above the opening 28 is the height of the remaining upper part after pre-cutting the lower part of the siding panel 3 installed directly above the opening 28 in the height direction. It is the height dimension. By pre-cutting, the siding panel 3 (1791-4) installed directly above the opening 28 is processed so that it has a stepped shape with a partially cutout (having a notch) at the bottom (East-2 ). For (East-4), the pre-cut height 21 is found in the same manner as above.

Note that if all siding panels 3 have the same standard height, the height of the top of the opening 28 is calculated from the standard height of the siding panel 3 installed directly above the opening 28. The precut height 21 of the siding panel 3 directly above the opening 28 can also be calculated as the difference obtained by subtracting the remainder after dividing by the standard height of 3.

(5) The siding panel 3 used in the siding panel pre-cut support system 15 described above will be described below.
The siding panel 3 used in the siding panel precut support system 15 has tiles 61 pasted on its surface.
As shown in FIGS. 7 to 9, the siding panel 3 may have a step 62 without tiles 61 on at least one of the upper and lower sides.

Here, the siding panel 3 is formed by pasting real tiles 61 on its surface. In the siding panel 3 of this embodiment, real tiles 61 are installed horizontally on the surface of a board material serving as a base. The tiles 61 are pasted in multiple stages in the vertical direction 6. As a result, the appearance of the building 1 that has been renovated using the tiled siding panels 3 is changed to a luxurious tiled or brick style.

A step 62 without a tile 61 is a specific step of the siding panel 3 where the tile 61 is not pasted and the base material is exposed, so the siding panel 3 is a blank step. 62, resulting in precut siding panels 63 to 65. A plurality of types of pre-cut siding panels 63 to 65 are formed depending on how the steps 62 without tiles 61 are installed.

As mentioned above, the pre-cut siding panels 63 to 65 are special siding panels 3 that have steps 62 without tiles 61 and are prepared as siding panels 3 exclusively for pre-cut. It is made on the premise that the blank stage 62 will be pre-cut at a factory. Note that, if necessary, tiles 61 can be cut to an appropriate size and pasted to the portion of the step 62 where there is no remaining pre-cut tile 61.

Specifically, FIG. 3 shows a standard siding panel 3 (891), in which tiles 61 are pasted in six rows in the vertical direction 6. This standard siding panel 3 is used for most of the exterior wall 2 of the building 1.

FIG. 5 shows a standard siding panel 3 (1791-4) with a reduced height dimension, in which four levels of tiles 61 are pasted in the vertical direction 6. The suffix (-4) indicates the size of four stages. This siding panel 3 having a small height dimension is appropriately used in a part of the outer wall 2 of the building 1 (for example, the top of the building 1, the opening 28, etc.) by replacing the standard siding panel 3.

FIG. 7 shows a pre-cut siding panel 63 that has a height of four levels and has the top level as a level 62 without tiles 61, and has tiles 61 pasted only in the lower three levels. There is. This pre-cut siding panel 63 is applied to a part of the part that has been replaced with a standard siding panel 3 with a smaller height dimension, such as the top of the building 1 or the lower side of the opening 28. It is suitable for cutting in whole or in part.

FIG. 8 shows a pre-cut siding panel 64 having a height of four levels and with the lowest level being a level 62 without tiles 61, and tiles 61 are pasted for the top three levels.

<Function> The function of this embodiment will be explained below.

In order to renovate a building 1 such as a house, a siding panel 3 is attached to the outside of an existing outer wall 2 of the building 1. Generally, siding panels 3 for renovation are prepared with standard dimensions and cut one by one to fit the building 1 at the renovation site, but the siding panels 3 are cut one by one at the renovation site. Since it is difficult to do this, most of the siding panels 3 (of which the ones that should be pre-cut) used for renovations are pre-cut at the factory, so that the pre-cut siding panels 3 can be simply attached at the renovation site. It is hoped that For that purpose, the siding panel precut support system 15 of this embodiment is used.

The siding panel pre-cut support system 15 allows siding panels 3 for renovation to be pre-cut at the factory, reducing construction costs at construction sites (for example, increasing site turnover and eliminating construction waits due to a shortage of construction companies). It becomes possible to aim for Furthermore, it is possible to reduce cutting noise and cutting dust (dust) at construction sites, and to reduce panel leftover materials at construction sites. In addition, it is possible to reduce nuisance to neighbors and improve customer satisfaction.

<Effects> According to this embodiment, the following effects can be obtained.

(Effect 1) The siding panel precut support system 15 includes a precut dimension calculation section 16. Thereby, it becomes possible to pre-cut the siding panel 3 for renovation based on the pre-cut dimensions calculated by the pre-cut dimension calculation unit 16, and it is possible to obtain the above-described effects of pre-cutting. The pre-cut dimension calculation unit 16 can obtain pre-cut dimensions for pre-cutting the siding panel 3 to a size suitable for the building 1.

In addition, when precutting the siding panel 3, there are two types of precut dimensions of the siding panel 3: a width dimension (precut width) and a height dimension (precut height 21). Of these, the precut width of the siding panel 3 is calculated by the layout setting section 27 of the siding panel expansion system 25 provided separately from the siding panel precut support system 15, so the precut dimension calculation section 16 of this embodiment The pre-cut height 21 of the siding panel 3 is mainly calculated. As a result, the width and height dimensions of the siding panel 3 can be pre-cut by the siding processing device at the factory based on the pre-cut width and pre-cut height 21 calculated by the layout setting section 27 and the pre-cut dimension calculation section 16. become able to.

The above-mentioned layout setting unit 27 determines the layout of the siding panel 3 in the width direction 31 with reference to the position 29 of the side part of the opening 28 of the building 1. By this allocation in the width direction 31, the precut width of the siding panel 3 is determined. Thereby, the siding panels 3 can be efficiently allocated to the outer wall 2 of the building 1 in the width direction 31. Then, the siding panels 3 are precut in the width direction 31 based on the layout in the width direction 31, and the precut siding panels 3 are stacked from bottom to top along positions 29 on the sides of the openings 28. The siding panel 3 can be installed in the building 1 in an orderly manner with the width end portions aligned vertically along the side position 29 of the opening 28.

At this time, if the height of the existing exterior wall 2 is an integral multiple of the height dimension of the siding panel 3, the siding panel 3 can be installed just right to match the height of the existing exterior wall 2, so the siding The panel 3 does not need to be pre-cut particularly in the height direction.

However, if the height of the existing exterior wall 2 is not an integral multiple of the height dimension of the siding panel 3, the siding panel 3 will not match the height of the existing exterior wall 2, so the siding The height of the panel 3 needs to be pre-cut to match the height of the existing outer wall 2.

Since the siding panels 3 are installed one after the other from the bottom, the last panel will not fit. Therefore, pre-cutting of the height dimension of the siding panel 3 only needs to be performed on the siding panel 3 at the top of the building 1 for the entire circumference of the building 1. As a result, most of the siding panels 3 other than the uppermost siding panel 3 can be used as they are at the standard height. Then, while minimizing the number of siding panels 3 whose height dimensions are pre-cut, the entire existing outer wall 2 can be successfully covered from bottom to top with the siding panels 3.

Therefore, the pre-cut dimension calculation section 16 of this embodiment includes an under-eave panel pre-cut dimension calculation section 22, and the under-eave panel pre-cut dimension calculation section 22 calculates the height direction of the siding panel 3 installed at the top of the building 1. The precut dimension (precut height 21) was determined. As a result, it is possible to obtain the pre-cut height 21 of the top siding panel 3 with a simple configuration, and the top siding panel 3 can be pre-cut just right to match the height of the existing exterior wall 2. becomes possible.
This eliminates the need to adjust the height of the uppermost siding panel 3 at the renovation site.

(Effect 2) The under-eave panel pre-cut dimension calculation unit 22 calculates the distance from the lower position 41 of the siding panel 3 (East-5 to East-9) installed at the top to the upper position 42 of the outer wall 2. Therefore, the pre-cut height 21 of the uppermost siding panel 3 may be used. Thereby, the precut height 21 of the uppermost siding panel 3 can be easily obtained.

(Effect 3) The precut dimension calculation section 16 may include an opening panel precut dimension calculation section 51. Thereby, the pre-cut height 21 of the siding panels 3 (East-1 to East-4) to be installed above or below the opening 28 of the building 1 can be calculated by the opening panel pre-cut dimension calculation unit 51. . Therefore, it is not necessary to adjust the height of the siding panel 3 installed above or below the opening 28 at the renovation site.

(Effect 4) The opening panel pre-cut dimension calculation unit 51 calculates the size from the lower position 52 of the siding panel 3 (East-1, East-3) installed directly below the opening 28 to the lower position 53 of the opening 28. The pre-cut height 21 of the siding panel 3 to be installed directly below the opening 28 may be determined by determining the distance up to the opening 28. Thereby, the pre-cut height 21 of the siding panel 3 installed directly below the opening 28 can be easily obtained.
Further, the opening panel pre-cut dimension calculation unit 51 calculates the range from the upper position 54 of the opening 28 to the upper position 55 of the siding panel 3 (East-2, East-4) installed directly above the opening 28. The pre-cut height 21 of the siding panel 3 installed directly above the opening 28 may be determined by determining the distance. Thereby, the pre-cut height 21 of the siding panel 3 installed directly above the opening 28 can be easily obtained.

(Effect 5) The siding panel 3 may have tiles 61 pasted on its surface. Thereby, by using the siding panel 3 on which the tiles 61 are pasted, the building 1 that has been renovated using the siding panel 3 can be changed to a tiled exterior that looks good and has a luxurious feel.

Furthermore, the siding panels 3 may include those having a step 62 without tiles 61 at the top or bottom (special pre-cut siding panels 63 to 65). As a result, when pre-cutting the siding panel 3 in the height direction, by using the pre-cut siding panels 63 to 65 having the step 62 without the tile 61, the portion of the step 62 without the tile 61 can be cut and used. This makes it possible to reduce the number of tiles 61 that are wastefully discarded by pre-cutting. Further, by using the pre-cut siding panels 63 to 65, it is possible to eliminate waste of tiles 61, and it is also possible to eliminate the trouble of attaching tiles 61 to the siding panel 3 unnecessarily.
