DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for rationally manufacturing a roof panel constituting a roof of a building such as a house, and a design apparatus.

[0002]

2. Description of the Related Art In a conventional general building such as a house, a roof is constructed by a carpenter at a construction site, in which a hut is assembled in a bundle, a main building, a rafter, and the like, and then a surface material such as a field board is attached. (First known example). This method has a problem that the work is performed at a high place, and the scaffold is unstable due to the inclination of the roof, which is dangerous and the productivity is low. Further, there is a problem that extra materials and face materials for the hut assembly need to be prepared so as not to be short on site, and the loss of materials is extremely large.

Recently, in order to solve the various problems in the above-mentioned on-site construction, a roof panel in which a roof of a target building is divided into a plurality of pieces is manufactured in advance at a factory stage, and the roof panel is constructed. A method (second known example) is adopted in which the work period is shortened by carrying in and installing on the site, and the work at a high place is reduced as much as possible.

[0004]

The roof panel according to the second known example is manufactured at a factory and then carried to the site by a transportation means such as a truck. In this case, to limit the size of the roof panel to the carrying capacity of the carrying means,
It is necessary to form a roof panel by dividing the roof of the target building into small pieces.

For example, a roof 500 having a flat surface shown in FIG.
Then, each inclined surface is divided into 501 to 506 plane elements, and the plane elements 501 to 506 are further divided into roof panel elements 5011 to 5063 as shown in FIG. I have. Then, a frame is formed for each of the roof panel elements 5011 to 5063, and as shown in FIG. 15, a roof panel is formed by attaching a field board to each frame.

[0006] Usually, the baseboard is precut in advance according to the shape of the roof panel. For this reason, compared with the method of the first known example, such as performing the work of laying a base plate, extra steps and a special cutting device, such as designing a cut shape of the base plate, are required. In addition, in the case of the triangular roof panels 5011, 5021, etc. constituting the protruding corners, an extra portion 603 must be cut obliquely from the standard plate 600 in order to remove a necessary base plate portion 601. There is a problem that 603 is generated as a large amount of material loss.

[0007] It is an object of the present invention to provide a method of minimizing the loss of a base plate and to easily manufacture a roof panel on a flat surface in the vicinity of a factory or a construction site, and to design the roof panel. And a device for performing the above.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a method of manufacturing a roof panel according to the present invention is a method of manufacturing a plurality of roof panels in which a base frame having rafters and a field board are united. The base frame has a predetermined external dimension, rafters are arranged in the same direction and at substantially equal intervals, and the baseboard is made of one or more boards and has an area capable of arranging a plurality of base frames. When the base frame and the base board are combined, the rafters of each base frame are arranged so as to be in the same direction, and after the base frame and the base board are combined, the base board is cut along the outer periphery of the base frame to obtain a plurality of pieces. Characterized by manufacturing a roof panel.

In the method of manufacturing a roof panel, the base frame of the roof panel is formed into a divided shape necessary for forming a target roof, and rafters are provided on the base frame in the same direction at substantially predetermined intervals. Create by placing.
Therefore, the base frame has several types of shapes depending on the position with respect to the roof. In addition, the field board is installed with one or more standard boards having an area capable of arranging a plurality of base frames constituting a target roof. Then, for the baseboard, a plurality of base frames are arranged so that the rafters are in the same direction and united, and thereafter, the baseboard is cut along the outer periphery of the base frame, whereby a roof panel can be manufactured. .

[0010] As described above, the base frames cut in correspondence with the individual base frames are not attached to the base frames. Instead, base frames having various shapes are formed on a plane formed of the base plates in a rational layout basis. Assigned to
Field board loss can be minimized.

In other words, the rafters of each roof panel are oriented in the same direction, and under these conditions, various combinations of base frames are made so as to minimize the area of the base plate, thereby minimizing the loss of the base plate. Can be set to

Further, after the base frame is allocated to the plane formed by the base board, the base board is cut along the outer periphery of the base frame, so that this work can be performed on a flat surface, and work at a high place is possible. The work safety can be improved and the construction period can be shortened.

In the above-mentioned method of manufacturing a roof panel, when connecting a plurality of base frames and a ground board, the plurality of base frames are matched in advance in the direction of rafters and the distance between adjacent base frames is set to a predetermined size. After setting and arranging, a base plate is arranged on the upper surface of the plurality of base frames and the base frame and the base plate are combined, or after laying a plurality of base plates in advance, on the upper surface of the laid base plate. It is preferable that the rafters are made to coincide with each other, the distance between the adjacent base frames is set to a predetermined size, a plurality of base frames are placed, and then the base frames and the base boards are combined.

In the above-described method for manufacturing a roof panel, after laying and arranging a base frame formed in advance, a base plate can be arranged on the base frame and assembled. in this case,
As described above, by arranging the base frames rationally, it is possible to minimize the loss of the base plate.

Further, after laying and arranging a field board in advance, a base frame can be arranged on the field board and assembled.
In this case, rafters capable of exhibiting sufficient strength more than the strength required for the roof panel were arranged in the same direction in a straight line and at equal intervals on the top of the laid field boards, and the field boards and the rafters were combined. Thereafter, the roof panel can also be constructed by cutting the baseboard and rafters (including cutting the rafters in the vertical direction).

In any of the above-mentioned methods, the loss of the base plate can be minimized and the safety can be improved.

In the above-mentioned method for manufacturing a roof panel, a plurality of base frames and a base plate are joined together, and a waterproof material including roofing is attached to the upper surface of the base plate, and thereafter, the base plate and the waterproof material are cut simultaneously. Is preferred. By manufacturing the roof panel in this manner, a waterproof roof panel can be manufactured.

Still another method of manufacturing a roof panel is to divide a target roof according to a first division rule including a maximum size of a vehicle, to set a roof panel, and to set an outer shape of the roof panel and a rafter. A first step of determining the length of the roof and its position in the roof panel, and all the roofs in the area where the loss of the first stage of the field board is taken into account in the actual area of the target roof. A second step of arranging the panels such that the rafters are arranged in the same direction and at substantially the same interval; A third step of arranging the roof panels so as to minimize the amount, a fourth step of arranging the roof panel groups divided according to the first division rule, and determining the actual loss area of the baseboard obtained in the third step. If necessary, the actual loss of the base plate will be further reduced. As described above, the plurality of roof panels arranged in the fourth step are appropriately moved to correct the arrangement position, or the first division rule is changed to repeat the first to fourth steps. And 5 steps.

In the method of manufacturing a roof panel, the roof panel is divided according to the first division rule including the size of the vehicle, and the divided roof panel is transported by making the most of the size of the vehicle. You can do it. The direction of the roof panel can be specified by setting the length and position of the rafter on the divided roof panel.

[0020] An area having an area that allows for the loss amount of the field board assumed in the first stage is set in the actual area of the target roof, and all the roof panels are oriented in the same direction with the rafters in this area. The roof panels arranged in the area of the base plate in consideration of the loss amount in the first stage are rearranged so as to minimize the loss amount of the base plate, and the actual loss area is determined. This makes it possible to minimize the loss of the field board. In particular, it is preferable to arrange a plurality of roof panels using rafters arranged on a straight line.

Further, if necessary, the rearranged roof panel is appropriately moved to correct the arrangement position.
By changing the division rule of and repeating the same thing again,
Roof panels can be manufactured rationally with less loss of field boards.

A roof panel designing apparatus according to the present invention is a designing apparatus for designing a building roof in accordance with a transportable dimension by a transportation facility, and includes a roof shape information stored in advance, and a roof board. The target roof is divided based on the unit dimensions, the permissible value of the actual loss amount of the baseboard, and the transportable dimensional data by the transportation equipment, the roof panel is set, and the outer shape of the roof panel and the length of the rafter set are set. A roof panel setting means for converting position information in the rafter roof panel into coordinate values, and all roof panels set by the roof panel setting means so that the rafters have the same direction and substantially the same interval. A roof panel arranging means for arranging and arranging the roof panels arranged so as to minimize the loss amount of the field board, and a roof panel arranged by the roof panel arranging means.

The method for manufacturing a roof panel according to the present invention is a method for manufacturing by dividing a roof A in a house as shown in FIG. 1 into a plurality of roof panels, for example. The transport efficiency is improved by taking into account the dimensions that can be transported by means of transport such as trucks, and the amount of loss of the roof boards and rafters constituting the roof panel can be minimized. .

In particular, in manufacturing a plurality of roof panels constituting the target roof A, the roof A is laid out in a minimum area by laying out the base frame constituting the divided roof panel as a reference. By minimizing the loss of the base plate, or laying the base plate and laying the base frame on this, the loss of the base plate is minimized and the roof panels constituting the roofs of multiple buildings are more rational. It can be manufactured.

The roof has various shapes from the viewpoint of the design of the target house. In the present embodiment, the roof A has six inclined surfaces 101 to 106 as shown in FIG.
Shall be constructed as a ridge roof with However, the method of manufacturing a roof panel according to the present invention is not limited to the roof shape of the present embodiment, but can be applied to a roof having another shape.

Prior to describing the method of manufacturing the roof panel according to the present embodiment, the structure of the roof panel B will be described with reference to FIG. The shape of the roof panel B does not correspond to any of the roof panels 1011 to 1063 described later,
It shows a general shape of the roof panel according to the present embodiment.

The roof panel B is constructed by attaching a base plate 2 to the upper surface of a base frame C. Base frame C
As shown in FIG. 1A, the rafter 3 is composed of rafters 3 arranged in parallel and at substantially the same intervals, a corner piece 4 and a nose plate 5. For this reason, the base frame C is formed corresponding to the shape of each of the roof panels 1011 to 1063 divided from the roof A.

The nose plate 5 is a member constituting the eaves side of the roof A, and is not necessarily an essential member. That is, when the nose plate 5 is unnecessary in the base frame C, the corner block 4 is arranged in place of the nose plate 5. Therefore, regardless of the presence or absence of the nose plate 5, the base frame C is preferably formed in a shape in which the outer periphery is closed by the rafter 3 and the corner block 4. That is, the roof panel B can be formed by combining the rafter 3 and the baseboard 2 and cutting them according to the preset shapes of the individual roof panels 1011 to 1063, and then attaching the corner boards 4 and the nose plates 5 to each other. is there. Further, the materials of the rafters 3, corner blocks 4, and nose plates 5 constituting the base frame C are not particularly limited, and steel, wood, or the like can be used. And the base frame C
Are connected to each other by means (e.g., welding, bolting, nails, screws, etc.) that are optimal for the respective materials.

As shown in FIG. 3B, the base frame C
The roof panel B is configured by attaching the base plate 2 to the upper surface of the roof panel B. Normally 910mm x 1820mm for field board 2
Plywood with dimensions of is used. Further, as shown in FIG. 3 (c), a waterproof roofing 6 serving as a surface material is attached to a roof panel B on which a field board 2 is attached on the upper surface of a base frame C, if necessary. Be composed.

In the first step, as shown in FIG. 3, the roof A is divided into a plurality of roof panels 1011 to 1011 according to a first division rule including a maximum size of a carrier such as a truck as a transportation means.
It is divided into 63 and the length of the rafter 3 constituting each roof panel 1011 to 1063 is determined.

Here, the first division rule includes conditions such as the maximum size that can be transported by the transportation means, the location of rafters, the location of corner blocks, and the interval between adjacent roof panels.

In this embodiment, the roof A is composed of 21 roof panels.
The division into 1011 to 1063 is mainly based on the loading dimensions of the truck. The size of the truck bed is not particularly limited, but it is preferable to assume a truck that can travel on a normal road without any particular limitation.

In the first division rule, a schematic shape of each roof panel is also defined, and the shape is contained in a pentagon including a triangle, a parallelogram, and a trapezoid. Therefore, there is no hexagonal or round-shaped roof panel.

Each roof panel 1011 to 1063 constituting the roof A
In FIG. 10, all the rafters 3 constituting each of the roof panels 1011 to 1063 are arranged along the inclination direction of the roof A, as shown in FIG. Therefore, by dividing the roof A into a plurality of roof panels 1011 to 1063, it is possible to determine the outer shape of each of the roof panels 1011 to 1063 and the length of the rafter 3 constituting each of the roof panels 1011 to 1063. .

Each roof panel needs to form some gap between it and other adjacent roof panels,
By forming this gap, when each roof panel 1011 to 1063 is arranged at a predetermined position when constructing the roof A, it is possible to realize a smooth arrangement without interfering with other adjacent roof panels. It becomes possible.

In the adjacent roof panels, rafters 3 are required at portions facing each other. It is preferable that the rafters 3 arranged in such a part be moved in parallel with each other to the inside of the roof panel so as not to interfere with each other when the roof panel is installed on site. However, it is not always necessary to move the rafters 3 of the opposing part of the adjacent roof panel in parallel with each other to form a gap between them, and it is sufficient to cut all rafters 3 in the vertical direction, for example. It may be made of a material having a cross section capable of exhibiting strength, and the rafter 3 at the opposing part of the adjacent roof panel is made of a material having a cross-sectional area twice or more than other rafters 3. After the configuration, it may be cut in the vertical direction and divided.

After the outer shape of each of the roof panels 1011 to 1063 and the length of the rafter 3 are determined as described above, in the second step, the roof A
Is set, and all the roof panels 1011 to 1063 are arranged in the area.

The actual area of the roof A can be calculated by adding the area of each plane constituting the roof A. The area of the roof A is equal to the area of the base plate 2 constituting the roof A. That is, when the area of the roof board 2 used in forming the roof A and the area of the roof A are the same, the loss amount of the roof board is 0 and the most efficient use is made.

Although the area of the roof A and the area of the used base plate are not actually the same, it is possible to reduce the loss amount of the base plate by adjusting the area so as to be as equal as possible. It is. That is, an area in which the first-stage loss amount is expected in the actual area of the roof A is set as an area of the base plate, all the roof panels 1011 to 1063 are arranged in this area, and the area of the area is reduced as much as possible. It is possible to reduce the amount of loss of the field board by making it smaller.

As shown in FIG. 5, the area D of the field board 2 having the area of the roof A in consideration of the loss amount at the first stage is formed by the standard board. It is possible to set a planar shape in which a number of standard plates serving as the base plate 2 are arranged. However, the shape of the region D is not uniquely set.

Next, all the roof panels 10 are located in the area D.
11 to 1063 are arranged. In this case, in the first step, the roof panels 1011 to 1063 divided as shown in FIG.
As shown in FIG. 5, the rafters 3 are arranged side by side so that the directions of the rafters 3 are the same, and the rafters 3 are arranged so as to have substantially the same interval. Furthermore, they are arranged so that the dimension in the direction along the rafter 3 and the dimension in the direction perpendicular to the rafter 3 can always correspond to the standard size of the base board 2. In particular, the rafters 3 are preferably arranged in the same direction and on the same straight line.

Arranging the rafters 3 at substantially the same interval does not mean that the intervals between the rafters 3 constituting the individual roof panels 1011 to 1063 are the same. That is, as described above, when the roof A shown in FIG. 10 is divided into a plurality of roof panels 1011 to 1063, a gap is formed between the rafters 3 arranged at the site where the adjacent roof panels face each other. is necessary.

In this embodiment, the positions of the rafters 3 are set such that the intervals between the center lines of the rafters 3 are the same. For this reason,
The rafters 3 located on both sides of each of the roof panels 1011 to 1063 are arranged such that the outer side faces coincide with the center line of the original rafters 3 or are located inside. Therefore, each roof panel 1011
The intervals between the rafters 3 to 1063 are not the same, and the rafters 3 located on both sides in the width direction are smaller than the interval between the rafters 3 located at the center. In this state, the rafters 3 are arranged at substantially the same interval. That is, the rafters 3 do not necessarily need to be arranged on a straight line, and all the rafters 3 need to be arranged in the same direction.

All the roof panels 1011 to 1063 set as described above are arranged in the area D shown in FIG. As described above, when all the roof panels 1011 to 1063 are arranged in the area D of the base plate 2, it is not possible to guarantee whether or not this arrangement state is the best arrangement state for minimizing the loss of the base plate 2. Absent.

For this reason, in the third step, the roof panels 1011 to 1063 arranged in the area D in the second step are rearranged again so that the loss amount of the base plate 2 given in the first step is minimized. I do. This work is performed with reference to the shape of the area D and the arrangement of the roof panels 1011 to 1063 in FIG. Then, as a result of this operation, the roof panels 1011 to 1063 are rearranged in the area E as shown in FIGS.

In arranging the roof panels 1011 to 1063 in the area E, it is general that the roof A has the same inclination in the same building, and the angle of the hatched portion in the triangular or trapezoidal roof panel is common. Are equal to each other. For this reason, roof panels with shaded parts, such as roof panels 1011 and 1042,
Each set of 1015 and 1024, 1012 and 1032, etc. has a shape that is easy to handle, such as a substantially square or rectangular shape, when the directions of the rafters 3 are arranged in the same direction and the hatched portions are opposed to each other.

Accordingly, all the roof panels 1011 to 1063 are combined with the diagonal portions facing each other or combined with the straight portions facing each other, and are arranged in the region E. It is possible to rearrange rationally.

Thereafter, in a fourth step, the actual loss amount of the base plate 2 is calculated, and if the calculated actual loss amount is satisfactory, the arrangement is completed. The actual loss amount can be easily calculated by calculating the used area by calculating the number of sheets of the standard size constituting the base plate 2, and calculating the difference between the calculated value and the actual area of the roof A. It is.

If the calculated actual loss is not satisfactory, the arrangement position is corrected again, or the division rule in the first stage is changed (for example, the loading capacity of the truck), and the division of the roof A is started again. carry out.

For example, if the layout state of the roof panels 1011 to 1063 with respect to the area E as shown in FIG. 8 is satisfied, the base frame C corresponding to the shape of each of the roof panels 1011 to 1063 is satisfied.
Are formed, and these base frames C are laid out on a plane according to FIG. Then, a standard-sized base plate 2 is laid on the upper part of the base frame C, and is combined by using an optimal means according to each material, for example, using a nail or a screw or using a bolt.

As described above, the base frame C and the base plate 2
Are combined, a panel having an area larger by the actual loss amount of the base plate 2 than the area where the target roof A is developed in a plane, and in which all the roof panels 1011 to 1063 are integrated, is formed.

Thereafter, the base plate 2 and all the roof panels 1011
~ 1063 integrated panels into individual roof panels 1011 ~ 10
Work to divide into 63. As shown in FIG. 9 (a), this work is performed, for example, at a portion where the roof panels 1042 and 1011 are opposed to each other, as shown in FIG. The field board 2 is cut by moving the saw blade 7 along. This cut produces roof panels 1011 and 1042. Then, the same cutting is performed for each of the roof panels 1011 to 1063 to manufacture all the roof panels 1011 to 1063.

As described above, since the plurality of roof panels 1011 to 1063 constituting the roof A are formed on a normal work plane rather than at a high place on the frame, the work is easy and safety is ensured. Is possible.

When the base frame C corresponding to the roof panels 1011 to 1063 and the base plate 2 as the region E are combined, the base frame C is laid below and the base plate 2 is laid on top of the base frame C. Alternatively, it is not particularly limited whether or not the base frame 2 is laid on the upper part of the field board 2 after the field boards 2 are laid and arranged in advance, and it may be appropriately selected according to the situation of the work place. . Whichever method is adopted, the base plate 2 and the base frame C can be combined.

After the base plate 2 and the base frame C are combined, it is advantageous to attach the waterproof roofing 6 to the upper surface of the base plate 2 before cutting the base plate 2 with the saw blade 7. . In this way, after the waterproof roofing 6 is constructed on the upper surface of the field board 2, the roofing panel 1011-
By manufacturing the 1063, it becomes possible to configure the waterproof roof panels 1011 to 1063 in one operation.

Next, a roof panel designing apparatus is shown in FIG.
This will be described with reference to the block diagram of FIG.

As described above in detail, in the method of manufacturing a roof panel according to the present invention, all roof panels are arranged with the rafters aligned in the same direction, and in this state, the roof panel is united with the field board. Furthermore, since the roof panel is manufactured by cutting the roof panel along the outer periphery of the roof panel, the loss of the roof panel and rafters can be minimized. In addition, since the work of manufacturing the roof panel can be performed on a predetermined work surface instead of at a high place above the skeleton, safety can be improved and efficiency can be improved.

Also, after attaching a waterproof roofing to the upper part of the field board, the roof panel having waterproof property can be manufactured by cutting the field board and the roofing,
In addition, it is possible to save harmful roofing as compared with a case where roofing is constructed after arranging roof panels and constructing a roof.

Further, in the method of manufacturing a roof panel, a roof of a target building is disassembled to set a plurality of roof panels,
Furthermore, when compared with the method of individually drawing and manufacturing this roof panel, the design time can be extremely shortened, the production efficiency in the factory can be improved, and the work time in the field can be further improved. Can be shortened. Therefore, it is possible to shorten the construction period.

In addition, the transportation efficiency can be improved by dividing all the roof panels constituting the target roof according to the division rule including the loading capacity of the transportation means without manufacturing the roof panels individually.

Further, in the roof panel designing apparatus according to the present invention, a reasonable roof panel is manufactured using a base plate in which a loss amount reduced as much as possible to the roof area of the target building is added. I can do it.
