Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof of a prefabricated building, and can be applied to, for example, a unit type prefabricated building having a roof of a dormitory or a roof of a purlin.

[0002]

BACKGROUND ART In recent years, a unit type prefabricated building has been constructed in which a living room or the like of a building is manufactured as a building unit in a factory, and these building units are transported to a construction site for construction. In such a unit type prefabricated building, a roof such as a dormitory roof or a main house roof is also usually provided with a plurality of roof units. In such a conventional roof unit, the roof is divided into a plurality of pieces in a plane shape in parallel with the end surface. The lower surface of each roof unit has a size substantially corresponding to the upper surface of the building unit to be placed.

[0003]

For example, in a two-story building unit, there is a so-called set-back type unit in which a part of the building unit of the second floor is retracted due to the restriction of diagonal lines. Since the roof dimensions of such building units are different from those of ordinary roof units, various roof units in which the roof is divided into multiple pieces in the vertical direction also have to be manufactured accordingly, which is troublesome to manufacture. It was

[0006] Further, it has been practiced to use the attic inside the roof as a storage room or the like. However, if the height of the roof is increased in order to increase the space at the inside of the attic, a divided roof unit is used. Even if there was, there was a problem of conflicting with transportation restrictions. Therefore, the present invention provides a unit roof for a prefabricated building that can easily cope with roofs having different shapes and sizes and does not violate transportation restrictions even if the height of the roof is increased. The purpose is to do.

[0005]

A unit type roof of a prefabricated building according to the present invention has a corner unit arranged at a corner of the roof, an intermediate unit arranged between the corner units, and the intermediate unit. And a ridge unit installed along the upper edge, wherein the intermediate unit and the ridge unit are selected from pre-fabricated ones having different sizes and shapes according to the size and shape of the roof. Is installed.

The prefabricated building includes a unit type prefabricated building, etc. The case where the intermediate unit and the ridge unit have different sizes and shapes is, for example, a case of a normal roof and a setback roof. The roof includes a hipped roof, a main house roof, and the like.

[0007]

The corner unit is manufactured as a common portion even if the roof has a different size and shape, and only the intermediate unit and the ridge unit are prepared by preparing a plurality of types according to the size and shape of the roof. Also, in the on-site roof assembly, the corner units can be commonly used and installed even if the roof dimensions are different, and only the intermediate unit and the ridge unit are prepared in advance. It suffices to install the one selected from the different sizes and shapes according to the size and shape of the roof.

As described above, even if roofs having different sizes and shapes are provided with a common ridge unit, compared with the case where roof units having different sizes and shapes must be prepared in accordance with roofs having different sizes and shapes. This is advantageous in manufacturing. Further, the common use of such members is efficient in storage and transportation.

Further, since the roof is composed of the ridge unit, the corner unit, and the intermediate unit, which are separated in a substantially horizontal direction, the height of each unit itself does not become so high as to impede transportation restrictions. Therefore, it is possible to provide a roof having a desired height without any transportation problem.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a normal (not setback) dormitory roof and a setback dormitory roof of a unit house will be described with reference to the drawings.
First, as shown in FIGS. 1 and 2, an embodiment in the case of a normal hipped roof will be described. The unit housing 11 of this embodiment has a two-story housing body 12 and a hipped roof 13.

The housing main body 12 is composed of six housing units 14 which are the first floor portions and six housing units 14 which are mounted on the housing units 14 and which are the second floor portions. The housing unit 14 is configured by attaching a wall panel 15 and the like to a unit frame (not shown) assembled by columns, beams and the like. The hipped roof 13 has a lower portion 17 having a substantially horizontal upper edge 16 and an upper portion having a substantially horizontal lower edge 18.
Consisting of 19. The attic 21 of the dormitory roof 13 serves as a storage room or the like.

The lower part 17 comprises four corner units 22 and two intermediate units 23. Two of each corner unit 22 are continuously installed on each of the one and the other flat sides, and each of the intermediate units 23 is installed between the corner units 22 on the one and the other end sides, respectively.

Each corner unit 22 and each intermediate unit 23 are
A roof panel 24 is stretched over a frame (not shown) assembled with beams and bundles. The upper part 19
Consists of one ridge unit 25. This building unit
As shown in FIG. 3, the reference numeral 25 is a frame panel (not shown) assembled with ridge beams, climbing beams, etc. and a roof panel 24 stretched over the frame.

Further, the ridge unit 25 is formed in such a length that the lower end portions 25A and 25B on the flat side and the wife side thereof slightly cover the corner unit 22 and the intermediate unit 23, thereby facilitating waterproofing. Has become. The height of the hipped roof 13 itself of this embodiment conflicts with the height standard based on transportation restrictions, but the heights of the units 22, 23, 25 of the lower part 17 and the upper part 19 are:
Each is within transportation limits.

Such a hipped roof 13 can be provided on the housing main body 12 as follows. First, in a factory, the housing unit 14 that becomes the housing main body 12 and the corner unit 22, the intermediate unit 23, and the ridge unit 25 that become the dormitory roof 13 are prepared and prepared. These units 22,23,25
Among them, only one kind is produced for the corner unit 22, but the intermediate unit 23 and the ridge unit 25 are for the normal dormitory roof 13 and the set-back ridge roof 26.
Plural types according to the size and shape of are also prepared.

Next, the housing unit 14, the corner unit 25, the intermediate unit 23 for the ordinary ridge roof 13, the ridge unit 25, etc. are mounted on a truck and transported to a predetermined construction site. Next, as shown in FIG. 1, after the six housing units 14 which are the first floor portions are installed on the foundation at the construction site, the six housing units which are the second floor portions are placed on these housing units 14. Place 14

Next, two of the corner units 22 are continuously installed on the flat side of the housing unit 14 on the second floor, and the intermediate unit 23 is installed between the corner units 22 on the wife side. Make the lower part 17 of the hip roof 13. Then this bottom 17
After placing the ridge unit 25 which is the upper part 19 on,
By joining the upper part 19 and the lower part 17, the ridged roof 13 of this embodiment is provided. As shown in FIG. 3, the ridge unit 25 may be supported on the housing unit 14 on the second floor by pillars 27 and placed on the lower portion 17.

On the other hand, as shown in FIGS. 4 and 5, in the setback type unit housing 28, one of the housing units 14 on the second floor of the unit housing 11 corresponds to the diagonal line restriction. And has retreated,
The setback hipped roof 26 of this unit house 28 also has a size and shape corresponding to the second floor portion. This setback dormitory roof 26 also has a lower part 31 similar to the ridge roof 13 above.
The upper unit 32 and the upper unit 32, but the intermediate unit 33 and the ridge unit 34 correspond to the setback, and the normal ridge roof 13
The size and shape are different from

That is, two corner units 22 which are continuously installed on each of the one flat side and the other flat side are the same as the corner units 22 for the ordinary hipped roof 13, but an intermediate unit 33. As compared with the intermediate unit 23 and the ridge unit 25, the ridge unit 34 is set back, and the dimension is shorter.

The intermediate unit 33 and the ridge unit 34 of the dormitory roof 26 are selected from a plurality of types prepared in advance according to the dimensions and shape of the ridge roof 26 for setback according to the dimensions and shape of the roof. It was done. Such a setback hipped roof 26 can be provided in the housing main body 35 in the same manner as the case of the normal hipped roof 13 described above.

According to the dormitory roofs 13 and 26 according to the above-described embodiment, the corner unit 22 is common even when the dimensional shape of the roof differs from that of the normal ridge roof 13 and the setback ridge roof 26. A plurality of types of intermediate units 23 and 33 and ridge units 25 and 34 are produced according to the size and shape of the roof. In the assembling of the roof at the site, even if the normal ridge roof 13 or the setback ridge roof 26 with different roof dimensions and shapes, the corner unit 22 is used.
Can be commonly used and installed.

On the other hand, the intermediate units 23 and 33 and the ridge unit
As for 25 and 34, it is possible to install the ones selected from the preliminarily prepared different size and shape according to the hipped roofs 13 and 26 of a specific size and shape. in this way,
Even if the hipped roofs 13 and 26 having different sizes and shapes have the common ridge unit 22, it is necessary to manufacture roof units having different sizes and shapes depending on the hipped roofs having different sizes and shapes. In comparison, parts such as beams and bundles are made common, which is advantageous in manufacturing.

Further, since the ridge unit 22 is commonly used, the number of types of members is reduced, which is efficient in storage, management and transportation. Furthermore, since each hipped roof 13,26 is composed of a ridge unit 25,34, a corner unit 22, and an intermediate unit 23,33, which are separated in a substantially horizontal direction, each unit 22,23,25 The height of 33,34 itself is not high enough to violate transportation restrictions. Therefore, there is no problem in transportation, and the hipped roofs 13 and 26 having a desired height can be provided.

In the above embodiment, the roof is a hipped roof 13,2.
Although it was the case of 6, the normal roof of the purlin shown in Figs.
The present invention can be similarly applied to the case of 41 and a setback purlin roof (not shown). That is, as in the case of the dormitory roofs 13 and 26 above, the normal roof 41
Both the lower roof and the upper roof for the setback
43, but the corner unit 44 has a common one, while the intermediate unit 45 and the ridge unit 46 have different sizes and shapes corresponding to a normal entrance roof 41 or a setback ridge roof. The ones are selected and installed.

[0025] The hipped roofs 13 and 26 and the ridged roof 41 are at the bottom.
It is also possible to configure 17,31,42 in common and to make only the upper part 19,32,43 different, and in this case, the corner part that forms the lower part 17,31,42 between both roofs 13,26,41. Unit 44 and intermediate unit
Since 45 can be shared, it is even more efficient during production and assembly.

Further, the fact that the roof is high causes the transportation restrictions to be violated not only in the case where the roofs 13 and 26 of the dormitory roof and the roof 41 of the gabled roof are continuously inclined and raised. As shown in FIG. 8, the lower part 52 and the upper part 53 of the roof 51 may be elevated with step portions 52A and 53A. Also for such a roof 51, a common one is installed for the corner unit 54, and a set back is selected for the intermediate unit 55 and the ridge unit 56, which are selected from those having different sizes and shapes. It can be arbitrarily adapted to roofs for commercial use.

Further, the ridge unit 25, 3 according to the above embodiment
4,46,56 is one, but may be divided into two or more. Further, the intermediate unit 55 according to the above-mentioned embodiment is a three-dimensional one, but it may be a panel-like one.

[0028]

According to the unit type roof of the prefabricated building according to the present invention, even roofs having different shapes and sizes can be easily dealt with, and even if the height of the roof is increased, transportation restrictions are imposed. There is no conflict.
