Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a roof structure for building units. Specifically, the present invention relates to a roof structure provided on a so-called trapezoidal building unit having a horizontal plane ceiling portion and an inclined plane ceiling portion.

[0002]

BACKGROUND ART As one of building units used in a unit construction method, for example, a part of a ceiling surface of a rectangular parallelepiped skeleton formed by columns and beams is obliquely inclined in order to cope with a north side oblique line restriction and the like. There is known a so-called trapezoidal building unit in which a horizontal plane ceiling portion and an inclined plane ceiling portion are formed.

Conventionally, the roof provided on the trapezoidal building unit includes a roof unit 4 installed on the horizontal plane ceiling 2 of the trapezoidal building unit 1 and a sloped ceiling 3 as shown in FIG. It is divided into a roof panel 5 placed on top. This is about the roof panel 5 part,
Even if it is shipped with it attached to the sloped ceiling part 3,
This is because the roof panel 5 can be attached to the sloping ceiling 3 of the trapezoidal building unit 1 in a factory for the purpose of reducing the on-site work since it can be accommodated within the transportation height limit.

Therefore, when a building such as a house is built using the trapezoidal building unit 1, as shown in FIG. 6, the roof panel 5 is preliminarily attached to the uppermost floor of the building body formed by combining a plurality of box-shaped building units 8. The trapezoidal building unit 1 is installed, the roof unit 4 is installed on the horizontal ceiling 2 of the trapezoidal building unit 1, and the roof unit 9 is installed on the building unit 8 on the top floor, and then the roof units 4, 9 It suffices to provide rain protection to the joint portion between the roof unit 4 and the roof panel 5 and the joint portion between the roof unit 4 and the roof panel 5.

[0005]

However, in the conventional roof construction method, it is necessary to provide rain protection to the joint portion between the roof unit 4 and the roof panel 75 at the construction site. Increase. In addition, since the rain scavenging work is performed at a high place on the roof, there is a drawback in that it is dangerous, difficult to perform, and efficient work cannot be performed.

An object of the present invention is to solve the above-mentioned conventional drawbacks and to provide a building unit having a horizontal plane ceiling portion and a sloping surface ceiling portion with which a roof can be efficiently constructed. To provide a roof structure.

[0007]

Therefore, a roof structure of a building unit of the present invention is a roof structure of a building unit provided on a building unit having a horizontal plane ceiling portion and a sloped ceiling portion, A roof panel whose dimensions are the same as or narrower than the width of the building unit and whose length is such that it covers the inclined ceiling of the building unit and extends over the horizontal ceiling, and this roof And a support member for supporting the panel in a state of being inclined along the sloped ceiling portion of the building unit.

[0008]

[Operation] In the construction of the roof, after the building unit is installed, it is sufficient to support the roof panel in a slanted state along the sloped ceiling portion of the building unit through the support member. It doesn't have to be protected from rain. Therefore, work on the roof at a high place can be eliminated, and efficient work can be performed without danger.

[0009]

Embodiments of the present invention will be described in detail below with reference to FIGS. In the description of these drawings, the same components as those in FIGS. 5 and 6 described above are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 1 shows the roof structure of the building unit of this embodiment. The roof structure is the trapezoidal building unit 1
Long roof panel 11 large enough to cover the entire ceiling surface
And a support member 12 for supporting the roof panel 11 in an inclined state along the inclined surface-shaped ceiling portion 3 of the trapezoidal building unit 1.

The roof panel 11 has a width dimension substantially the same as the width dimension of the building unit 1, and a length dimension covers the inclined plane-shaped ceiling portion 3 of the trapezoidal building unit 1 and the horizontal plane-shaped ceiling portion 2. It has a length dimension that spans over. Specifically, the length L ₁ of the inclined planar ceiling portion 3, and the length dimension L ₂ which corresponds to the hypotenuse of a right triangle having the base a horizontal plane ceiling section 2, projecting from the inclined surface shaped ceiling 3 It has a length dimension obtained by adding the length dimension L ₃ .

The support members 12 are vertically provided on both sides of the horizontal plane ceiling portion 2 of the trapezoidal building unit 1 opposite to the inclined plane ceiling portion 3, and the upper end portion of the roof panel 11 is provided. The two bundles 21 and 22 to be supported and the roof panel 1 fixed to both sides of the inclined surface-like ceiling portion 3 side
Two brackets 23, 24 supporting almost the middle part of 1
It consists of and.

Therefore, in this embodiment, when a building such as a house is built using the trapezoidal building unit 1, the trapezoidal building unit 1 is installed on the uppermost floor of the main body of the building, and the trapezoidal building unit 1 is mounted on the horizontal plane ceiling portion 2. After the two bundles 21 and 22 and the two brackets 23 and 24 are fixed, the roof panel 11 may be fixed to the bundles 21 and 22 and the brackets 23 and 24. It eliminates the need for a rain barrier between the unit and the roof panel. Therefore, work on the roof at a high place can be eliminated, and efficient work can be performed without danger.

Further, as shown in FIG. 2, two bundles 21 and 21 are provided.
By changing the length dimension of 2 and the inclination angles of the two brackets 23, 24, respectively, without changing the frame structure of the trapezoidal building unit 1, that is, without changing the form of the trapezoidal building unit 1, the roof panel 11 The gradient of can be changed arbitrarily.

In the above embodiment, the roof panel 11
And two bundles 21,22 and two brackets 23,2
Although the roof is composed of 4 and 4, it is not limited to this, and the roof structure shown in FIGS. 3 and 4 may be used.

In the roof structure shown in FIG. 3, the support member 12 is a right-angled triangular mount 31 when viewed from the side. The pedestal 31 includes a base frame 32 having substantially the same frame shape as the contour shape of the horizontal plane ceiling portion 2 of the trapezoidal building unit 1, and bundles 33 and 34 erected on both sides of the inner end side of the base frame 32.
Beams 35 connecting the upper ends of the bundles 33 and 34, and the bundles 3
It is composed of diagonal members 36 and 37 that are obliquely provided on both sides of the outer edge side of the base frame 32 from the upper ends of the members 3 and 34. In this case, after the pedestal 31 is installed on the horizontal ceiling 2 of the trapezoidal building unit 1 installed on the top floor of the building body,
Since it is sufficient to fix the roof panel 11 to the hypotenuse of the pedestal 31, the number of parts is smaller than that in FIG.

In the roof structure shown in FIG. 4, the roof panel 11 is integrally assembled to the oblique side of the pedestal 31 to form a roof unit. In this way, all the construction is completed by simply installing the pedestal 31 on the horizontal ceiling 2 of the trapezoidal building unit 1, so the work on site can be further reduced compared to FIG.

In the above embodiment, the width dimension of the roof panel 11 is the same as the width dimension of the building unit 1.
It may be narrower than the width dimension of the trapezoidal building unit 1. Furthermore,
Regarding the length dimension, if the length dimension covers the inclined surface-shaped ceiling portion 3 of the trapezoidal building unit 1 and extends over the horizontal plane-shaped ceiling portion 2, the length corresponding to the entire length of the trapezoidal building unit 1 is provided. You don't have to.

[0019]

As described above, according to the roof structure of the building unit of the present invention, the roof can be efficiently constructed in the building unit having the horizontal plane ceiling portion and the inclined plane ceiling portion.
