DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure of a unit-type building. For example, the present invention relates to a unit-type building comprising a box-shaped standard unit and a trapezoidal unit in which the upper surface of the standard unit is a slope. It can be used when installing a roof.

[0002]

2. Description of the Related Art A unit-type building is a building in which a plurality of building units and the like previously produced in a factory are combined at a construction site, and is standardized in dimensions to improve productivity in the factory and to mass-produce. It is a construction method that was considered for the purpose of conversion. Therefore, it is preferable that all building units use standardized units. Here, the building unit, which is a box-shaped standard unit, has four columns erected at four corners and four columns connecting the upper and lower ends of these columns.
The book is provided with a framework composed of a ceiling beam and a floor beam, and a ceiling material, a floor material, an inner wall, an outer wall, and the like are attached to the framework.

[0003] However, building units other than the standard units have been manufactured to meet actual building conditions and laws and regulations. As an example, there is a trapezoidal unit in which a horizontal part and a slope part are formed on the upper surface of the above-mentioned standard unit. This trapezoidal unit is mainly used to comply with the diagonal limit of the Building Standard Law such as the north diagonal line,
The purpose was to keep the eave height on the north side lower than the eave height of the standard unit.

[0004] As a roof of a unit-type building in which such a trapezoidal unit and a standard unit are combined, there are a roof type that extends from the standard unit to a horizontal portion of the trapezoidal unit and continuously covers a slope portion of the trapezoidal unit. The roof covering the horizontal part of the trapezoidal unit from the standard unit and the roof provided on the slope of the trapezoidal unit are divided and mounted near the intersection of the horizontal part and the slope of the trapezoidal unit, and finally the roof finishing material There has been proposed a type having a continuous roof, for example.

[0005]

By the way, in a unit building constructed by combining only a plurality of standard units,
Since the height of each building unit is the same, the roof used for such a unit-type building is, for example, a standard roof having a symmetrical cross section in the girder direction and the eave direction. For this reason, the eave height of the roof of such a unit building is constant.

However, in the roof structure of the unit-type building as described above, the eave height of the roof on the side of the standard unit and the eave of the roof of the trapezoidal unit where the slope is lowered are different, so that the standard roof is used. There is a problem that the roof cannot be used, and the roof that continues up to the slope must be specially manufactured, and the number of types of roofs must be increased. In addition, when a trapezoid unit with a length longer than the standard unit is combined with the standard unit so that its slope protrudes outside the standard unit, the eaves gutter attached to the eaves on the standard unit side is attached to the trapezoid unit. The standard eaves gutter used for the standard unit cannot be used because it must be installed as long as possible, and a special eaves gutter must also be attached to the eaves of the sloped roof. Therefore, there is a problem that variations of the eaves gutter increase.

An object of the present invention is to provide a roof structure of a unit type building which can use a standard type roof used for a standard unit even when it is necessary to lower a northern eave due to a northern oblique line. is there.

[0008]

Roof construction unitary building according to the present invention SUMMARY OF THE INVENTION comprises a box-shaped standard units, trapezoidal units are top with horizontally adjacent became horizontal portion and the slope portion in the standard unit DOO Te roof construction smell comprise configured unitary building, inclined toward the eaves from ridge
A first roof obliquely, is constituted and a second roof that will be the first roof and discontinuously formed, the first roof
Is the water of the standard unit and the trapezoidal unit.
Cover the portion beyond the intersection of the flat part and the slope part,
The roof has one end inclined with the horizontal part of the trapezoidal unit.
It is located at the intersection with the distribution part and the slope from the intersection.
Along the trapezoidal unit of the first roof
The tip of the side eaves and one end of the second roof are in a horizontal plane.
The feature is that they do not overlap .

In the roof structure of the unit building,
The first roof and the second roof are different from each other in that the second roof is the first roof.
May be arranged with a step below the roof of the first roof, and the eaves of the first roof may overlap with the second roof.

[0010]

According to the present invention, since the second roof is provided on the upper surface of the slope of the trapezoidal unit, it is not necessary to extend the first roof to the slope of the trapezoidal unit. Since the standard roof used for the unit type building in which only the standard units are combined can be used as the first roof as it is, the roof can be commonly used, and the number of types of roofs does not need to be increased.

In the roof structure of the unit building,
If the first roof and the second roof are arranged with a step below the first roof, the step allows for better ventilation, for example, ventilation in the attic. It will be good. Further, when the eaves of the first roof overlap with the second roof, it is difficult for rainwater or the like to enter due to the overlap, so that the roof structure has a good rain finish.

[0012]

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show a unit-type building 1 to which the roof structure of the present embodiment is applied. The unit building 1 includes a plurality of lower-floor building units 3 installed on a foundation 2, a plurality of upper-floor building units 6 placed on these lower-floor building units 3, And a roof 20 attached to the floor building unit 6.

The lower-floor building unit 3 is composed of a box-shaped standard unit 4 and a box-shaped standard unit 5 having a longer length than the standard unit 4.
A standard unit 7 having the same length as the standard unit 4 and disposed thereon, and a standard unit 5 having the same length as the standard unit 5 and disposed thereon, and having a horizontal surface 8A and a slope 8B. Then, as shown in FIG. 2, the slope portion 8B of the trapezoidal unit 8 is arranged on the eaves side of the unit building 1 and is arranged so as to protrude outside the standard unit 7 adjacent to the girder side. ing.

As described above, the trapezoidal unit 8 is
A and a slope portion 8B, as shown in FIG. 3, two columns 9 having a shorter height than the columns of the standard unit.
A ceiling beam 10 connecting the upper ends of the columns 9 to each other; a ceiling beam 11 connected to the upper end of a column having the same height as a column of a standard unit (not shown) to form a horizontal portion 8A;
Gradient part 8B spanned from 1 to short beam 9 of ceiling beam 10
And a trapezoidal skeleton 13 formed by two oblique beams 12 forming the ceiling material 14 and the inner wall 1.
5 and the outer wall 16 are attached. In addition,
A small beam 17 is bridged between the opposed diagonal beams 12, and the diagonal beam 12, the small beam 17, and the ceiling beam 10 form a roof panel 18 constituting a second roof 31 described later. The height of the diagonal beam 12 is formed smaller than the height of the ceiling beam 11, and one end of the diagonal beam 12 is connected to the lower end of the ceiling beam 11 , that is, the horizontal portion 8A.
It is mounted so as to be aligned with the intersection with the arrangement part 8B .

As shown in FIGS. 1 and 2, the roof 20 extends from the standard upper floor building unit 7 to the horizontal portion 8A of the trapezoidal unit 8.
The first roof 21 and the first roof 2
The first roof 21 has a step below the first roof 21 and is provided on the upper surface of the slope 8B of the trapezoidal unit 8.
1 and 1.

As shown in FIG. 3, the first roof 21 has a floor frame 22 for a roof installed on the ceiling beam 11 of the trapezoid unit 8, and a trapezoid The unit 8 is provided with a roof panel 24 attached at substantially the same inclination angle as the inclination angle of the inclined portion 8B in the unit 8. The roof panel 24 is provided with a panel frame 25 formed in a frame shape and a roof material 27 attached to the panel frame 25 via a base plate 26. In addition, support 2 is placed on the eaves of the first roof 21.
An eaves gutter 29 is attached via the eaves 8, and in order to close a gap between the eaves gutter 29 and the floor frame 22, the eave gutter 30 is attached to the eaves gutter 29.
It is attached between 9,22. The eave material 30 is provided with a large number of ventilation holes 30A for improving ventilation of the attic hut.

The second roof 31 is constructed by mounting a roofing material 33 on the roof panel 18 via a base plate 32. The support 3 is also provided at the eaves of the second roof 31.
An eaves gutter 35 is attached via the base 4.

According to the above-described embodiment, the following effects can be obtained. That is, since the second roof 31 capable of coping with the oblique line on the north side is attached to the slope 8B of the trapezoid unit 8, it is not necessary to extend the first roof 21 to the lower end of the slope 8B. May cover the upper floor standard unit 7 and the horizontal portion 8A of the trapezoidal unit 8. For this reason, since a standard roof used for a unit-type building composed of a plurality of standard units can be used as it is, the roof can be shared and the number of types of roofs does not need to be increased.

Further, the eaves gutter 29 of the first roof 21 is provided continuously irrespective of the second roof 31, and the eaves gutter 29 of the standard type can be used as it is. Unlike the prior art, the eaves gutter of the part of the roof leading to the slope part does not have to be used separately from the eaves gutter at the tip of the slope part, and the variation of the eaves gutter can be reduced.

Further, the first roof 21 and the second roof 31 are mounted with a step, and a number of ventilation holes 30A are formed in the eave material 30 of the first roof 21. Therefore, ventilation under the eaves of the first roof 21 is improved, so that ventilation of the attic is performed well.

Further, since the eaves of the first roof 21 overlap the second roof 31, it is difficult for rainwater or the like to infiltrate, thereby providing a roof structure with good rain. In the second roof 31, the height of the oblique beam 12 is smaller than that of the ceiling beam 11, so that the two beams 1
When the second and third roofs 3 and 2 are joined together, a gap is formed between the upper end of the ceiling beam 11 and the upper end of the oblique beam 12.
There is also an effect that it is easy to attach the roof material 33 and the like, and it is also easy to finish the rain.

The present invention is not limited to the above-described embodiment, but includes the following modifications as long as the object of the present invention can be achieved. For example, in the above-described embodiment, the second roof 31 is attached to the trapezoidal unit 8 in which the slope portion 8B protrudes in the long side direction of the unit-type building 1, but is not limited thereto, and as shown in FIG. The present invention can be used not only when the slope of the trapezoid unit 41 is protruded not only on both sides in the long side direction of the unit building 40 but also when the slope of the trapezoid unit 43 protrudes in the short side direction of the unit building 40. In this embodiment, as the first roof 21, the roof 21 of the above embodiment is used as it is, followed by three second roofs 42, 42, 44. Also, as shown in FIG. 5, the trapezoidal unit 51 may have a sloped part that is continuous with one side of the unit building 50 in the long side direction and protrudes in the short side direction of the unit building 50 as well. Available. In this embodiment, the first roof 21 is the same as the roof 21 of each of the above-described embodiments, and is followed by two second roofs 21.
Roofs 52 and 53 are used.

Incidentally, in the case of a house maker, on the one hand, a plurality of plans having different areas must be prepared in advance in order to meet the demands of the user. Since the restrictions are particularly large, they have conflicting themes that they must try to share parts as much as possible. But,
According to the embodiment and the embodiment shown in FIGS. 4 and 5, the first roofs 21 of the unit-type buildings 1, 40 and 50 can be commonly used, and the first roof 21 is used. It is possible to build unit-type buildings with various plans with different areas. Therefore, in each embodiment of the present invention, the two conflicting themes can be solved simultaneously.

In the above-described embodiment, the roof structure of the unit-type building is constituted by the first roof 21 and the second roof 31 having steps, but the present invention is not limited to this. A gap is provided between the first roof and the second roof,
For example, a so-called inner gutter type roof having a gutter attached to the gap can be used.

[0025]

As described above, according to the roof structure of the unit-type building of the present invention, the second roof is provided on the upper surface of the slope portion of the trapezoidal unit. It is not necessary to extend to the slope of the trapezoidal unit,
The first roof may cover the upper floor standard unit and the horizontal portion of the trapezoidal unit. For this reason, since the standard roof used for the unit-type building composed of a plurality of standard units can be used as it is, it is possible to use the roof in common, and there is an effect that the number of types of the roof does not need to be increased.

Further, the first roof and the second roof are arranged so that the second roof has a step below the first roof. Ventilation under the eaves is improved, and ventilation in the attic is improved.

Furthermore, since the eaves of the first roof overlap with the second roof, it is difficult to infiltrate rainwater or the like by the overlap, so that a roof structure with good rain closing is obtained. .
