DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of allocating a roofing material (tile) to a roof unit of a unit house.

[0002]

2. Description of the Related Art Conventionally, when building a unit house,
After the entire roof is made up of roof units, roof panels, etc., it is summed up locally and the roofing material is laid on the roof.
(Roof) is assigned (for example, see Japanese Utility Model Publication No. 1-20408).

[0003]

However, in the conventional method for allocating roofing materials for unit houses, since the roofing material allocation is performed on site, the installation of the roofing materials is always a local operation.

If it is possible to allocate a roofing material to each of the adjacent roof units in a single module, it is possible to carry out blackout at the time of unit production at a factory instead of at the site, and to apply to each unit On the other hand, roofing work at a factory can be easily performed regardless of the plan and scale of the completed unit house.

At this time, as shown in FIG. 1, each unit 1 is composed of a plurality of internal modules 2 having a length P in the roof material arranging direction. End modules 3 and 3 having a length A at a distance from each other, and being separated from the adjacent unit 1 by a distance B in the roofing material allocating direction. Even when the roof material is assigned with the height P as the module unit length of the roof material, a difference may occur in the relative position between the unit 1 and the roof material. That is, when laying the roof material over the adjacent units 1 and 1, the roof material on one unit 1 side and the roof material on the other unit 1 side shift, and these roof materials are connected neatly. It may not be possible.

The present invention is intended to solve such a problem. A roof material can be allocated to each unit by a single module, and a roof in a factory can be provided regardless of the plan and scale of a completed unit house. It is an object of the present invention to provide a roof material allocating method for a unit house which can perform a material construction.

[0007]

In order to achieve the above object, a roof material allocating method for a unit house according to the present invention comprises a plurality of internal modules having a fixed length P in a roof material allocating direction, and a plurality of these internal modules. Are arranged on both ends of the unit, and are arranged adjacent to each other at an interval B in the roofing material allocation direction. When laying roof materials, the following conditional expression (1): | (P
/ N) × n− (2A + B) | <C (where C is the allowable range of the displacement of the roofing material), a natural number N, n is determined, and the module unit length p of the roofing material is defined as P / N. Features.

[0008]

In the above-described method for allocating roof materials for unit houses according to the present invention, a natural number N that satisfies the conditional expression (1) is obtained, and the unit length p of the roof material (the pitch between the ridges of the roof material) is set to P / N. In this way, on the internal module constituting the unit, a roofing material having a length of N × p can be allocated, but on a portion that spans adjacent units, that is, on a portion that covers the end module and the unit gap. In, by using a roof material having a length of nxp, the roof material can be allocated while keeping the deviation within the allowable range C.

Therefore, the roofing material can be allocated to the adjacent units by a single module (single mountain pitch), and the roofing material can be partially allocated to the roof unit at the factory.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view showing a method of allocating a roof material for a unit house according to an embodiment of the present invention.

Also in this embodiment, for example, as shown in FIG. 1, each unit 1 has a plurality (three in the figure) of internal modules 2 having a length P in the roof material allocating direction, and these internal modules 2 And end modules 3 and 3 which are respectively disposed at both ends of the roof material and have a length A in the roofing material arranging direction.
Consider a case where a space B is provided between the adjacent units 1 in the roofing material allocation direction.

Here, as a specific numerical example, P = 90
Assuming that 0 mm, A = 120 mm and B = 10 mm, and that the allowable deviation range C of the roofing material is 1 mm, the conditional expression (1):
(P / N) × n− (2A + B) | <C
For example, N = 7 and n = 2 are obtained.

Therefore, the module unit length of the roofing material (tile) of this embodiment, that is, the pitch p of the roofing material is P / N.
≒ 128.4 mm.

As shown in FIG. 2, a mountain pitch p = 128.
4mm, 9 roofs 4a (), 5 roofs 4b (),
Using four roof materials 4c () and three roof materials 4d (),
These roofing materials 4a to 4d are 4740 mm long and 21 cm wide.
FIG. 3 shows an example in which the unit is allocated on a unit 1 having a length of 60 mm.
FIG. 4 shows an example in which the units are allocated on a unit 1 having a size of 640 mm and a width of 2160 mm. In FIGS. 3 and 4, reference numeral 5 denotes a crosspiece, reference numeral 6 denotes a suspension bolt, and roof materials 4a to 4d are denoted by reference numerals 1 to 4, respectively. The roofing materials 4a to 4d shown in FIGS. 3 and 4 are to be mounted at the time of the roof panel.

The roofing materials 4a to 4d as shown in FIGS.
Is carried out at the time of manufacture of the unit 1 at the factory, and the unit 1 on which such an assignment has been made is conveyed to a unit housing construction site, and when these units 1 are assembled, the units 1 and 1 arranged adjacent to each other are assembled. Suitable roofing materials 4a to 4d are arranged so as to straddle each other.

FIGS. 5 and 6 show specific examples. Here, FIG. 5 shows a case where the distance between the ridges of the roof materials 4 and 4 previously allocated in the factory on the adjacent units 1 and 1 is 770.8 mm. Similarly, FIG.
This is the case where the distance between the hills of the roof materials 4 and 4 previously allocated by the factory on the units 1 and 1 arranged adjacently is 257.2 mm.

In the case as shown in FIG. 5, four roof materials 4c
By using two sets, it is possible to allocate the hills of the roofing materials 4 and 4. That is, as shown in FIG. 5, the actual distance between the hills is 770.8 mm, while the two roof materials 4
The crest distance between both ends of c and 4c is 128.4 × 6 = 770.4 mm
The deviation is only 0.4 mm, which is well within the tolerance of 1 mm.

Also, in the case shown in FIG. 6, the use of one set of three roof materials 4d makes it possible to allocate the space between the roof materials 4 and 4. That is, as shown in FIG. 6, while the actual mountain distance is 257.2 mm, the roof material 4d
The distance between the peaks at both ends is 128.4 × 2 = 256.8 mm, and the deviation is also only 0.4 mm, which is well within the tolerance of 1 mm.

As described above, according to the roof material allocating method of the unit house of the present embodiment, the roof materials 4, 4a to 4d are placed on the adjacent units 1, 1 by a single module length (single mountain The pitch can be assigned by (p), and roofing work can be performed at the factory regardless of the plan and scale of the completed unit house.

In the above embodiment, P = 900 mm, A
= 120 mm, B = 10 mm, C = 1 mm, etc., but the method of the present invention is not limited to these numerical values. In addition, although the description has been given of the allocation of the roofing material, the method of the present invention is applicable not only to the roofing material but also to the roofing material.
The present invention can also be applied to the allocation of other building materials that can be allocated across one unit.

[0021]

As described in detail above, according to the method for allocating roofing material for a unit house according to the present invention, a plurality of internal modules having a fixed length P in the roofing material allocating direction, and both ends of these internal modules are provided. In a case where units each including an end module having a predetermined length A in the roof material allocation direction and being arranged adjacent to each other with an interval B in the roof material allocation direction, the roof material is placed on the roof of the unit.
