BACKGROUND OF THE INVENTION
The present invention relates to a building unit and a roof structure of a unit building using the building unit.
[0002]
[Prior art]
Japanese Patent Laid-Open No. 9-125585 discloses an invention of a roof structure of a unit building configured by installing a roof panel on a plurality of building units in which pillars, floor beams and ceiling beams are assembled in a frame shape. The invention described in this publication is configured by attaching a roof panel along the inclined surface of a trapezoidal unit formed in a box shape including an inclined surface at the top (first prior art). In the first prior art, as shown in FIG. 8, a roof support 3 such as a bundle or a truss is installed between the trapezoidal unit 1 and the roof panel 2.
[0003]
Moreover, there exists what is shown in FIG.9 and FIG.10 as a 2nd prior art of the roof structure of a unit building. In this second prior art, the building unit 10 includes a column 11, a floor beam 12, and a ceiling beam 13 assembled in a frame shape, and one girder ceiling beam 13A constituting the ceiling beam 13 is replaced with the other girder ceiling beam 13B. Lower end positions are joined to the pillar 11 and the end ceiling beams 13C and 13D constituting the ceiling beam 13 are joined to the pillar 11 via the joint piece 14 at the same horizontal position as the girder ceiling beams 13A and 13B, and are inclined. It has been done. A plurality of ceiling joists 15 and 16 are arranged between these ceiling beams 13 </ b> A to 13 </ b> D so as to be orthogonal to each other, and a ceiling member 17 is fixed to the lower surface of the ceiling joists 15, so that the ceiling portion of the building unit 10 can be obtained. 18 is configured.
[0004]
The roof panel 19 placed on the building unit 10 has a roof surface material 21 fixed to the upper surface of the roof joist 20, and a fixing bracket 22 is attached to the lower surface of the roof joist 20 at right angles to the roof joist 20. The fixing bracket 22 is spanned over the end ceiling beams 13 </ b> C and 13 </ b> D of the building unit 10, and the roof panel 19 is supported by the ceiling portion 18 of the building unit 10. In addition, the code | symbol 23 in FIG. 10 is the attachment wooden frame of a roof window.
[0005]
[Problems to be solved by the invention]
However, as shown in FIG. 8, a roof unit 5 having a gable roof surface is installed on one of the plurality of building units 4 having a rectangular parallelepiped shape, and the plurality of building units 4 are arranged. When the trapezoidal unit 1 according to the first prior art is disposed adjacent to the roof, the roof panel 2 and the roof panel 6 are continuously provided on the roof surface of the building unit 4, so that various types of roof supports 3 having different heights are provided. , 7 must be used, which increases the cost.
[0006]
In the second conventional technique, the height of the roof panel 19 is adjusted using the fixing brackets 22 having different heights. In the second conventional technique, the ceiling beams 13A to 13D of the building unit 10 are used. The ceiling joists 15 and 16 must be mounted on the ceiling 18 so that the productivity of the building unit 10 cannot be improved.
[0007]
Further, in the second prior art, a gap 24 corresponding to the height of the fixing bracket 22 is formed between the roof panel 10 and the ceiling portion 18, so that the height of the ceiling portion 18 of the building unit 10 is increased. I can't let you.
[0008]
The subject of this invention is made in view of the above-mentioned situation, and in invention of Claim 1 or 2, it is providing the building unit which can reduce the cost for attaching a roof panel. In the invention according to Item 3 or 4, the roof of the unit building can improve the productivity of the building unit, can set the ceiling height of the building unit high, and can further reduce the cost for attaching the roof panel. To provide a structure.
[0009]
[Means for Solving the Problems]
According to the first aspect of the present invention, a column, a floor beam, and a ceiling beam are assembled in a frame shape, and a pair of ceiling beams of a first set of two pairs of ceiling beams that face each other. One is joined to the column at a position lower than the other, and the second pair of ceiling beams are inclined and joined to the columns so as to be substantially continuous with the first set of both ceiling beams. The building unit is configured such that a roof panel can be installed above the first set and the second set of ceiling beams, and at least an end portion of the second set of ceiling beams on the high-position side is provided. The end of the first set of ceiling beams is joined to the pillar at a position lower than the pillar joining position, and the end portion on the side of the high slope is joined to the pillar via a horizontally bent joint piece , When a base is fixed to the upper end of a column to which one of a pair of ceiling beams is joined And fixing the pedestals to the upper ends of the columns to which the other one of the pair of ceiling beams is joined, providing a support surface along the inclination of the roof panel on each pedestal, and attaching the roof panel to each pedestal It is what I supported .
[0011]
The invention according to claim 2 is a roof structure of a unit building in which a roof panel is placed on a building unit configured by assembling pillars, floor beams, and ceiling beams into a frame shape. Of the two pairs of ceiling beams facing each other, one of the first pair of ceiling beams is joined to the column at a position lower than the other, and the second pair of ceiling beams is Inclined so as to be substantially continuous with both the first set of ceiling beams and joined to the column, and at least the end portion of the second set of ceiling beams on the high-position side is the first set of ceiling beams. It is joined to the above-mentioned column at a position lower than the column-joining position, and the end portion on the side of the high slope is joined to the column via a horizontally bent joint piece, and the first pair of ceiling beams While fixing the pedestal to the upper end of the column to which one is joined, The base is fixed to the upper end of the column and the other set of the pair of ceiling beams are joined at their respective base provided a support surface along the slope of the roof panel to support the roof panels to their respective pedestals, the A ceiling structure including a ceiling joist and a ceiling surface material is installed on the lower surface of the roof panel.
[0013]
The invention described in claim 1 has the following action.
Since at least one end of the second set of ceiling beams is joined to the column of the building unit at a position lower than the column joining position of the first set of ceiling beams, and these columns support the roof panel, the roof In order to install the panels on the building unit, it is not necessary to install various types of roof supports such as bundles and trusses having different heights between the roof panel and the building unit. Cost can be reduced.
[0014]
The invention according to claim 2 has the following effects.
Since the ceiling structure including the ceiling surface material and the ceiling joists are installed on the lower surface of the roof panel, it is not necessary to mount the ceiling structure between the ceiling beams of the building unit. For this reason, it becomes easy to assemble the ceiling of the building unit, and the productivity of the building unit can be improved.
[0015]
In addition, since the ceiling structure including the ceiling panel and ceiling joists was installed on the lower surface of the roof panel, there was no gap between the roof panel and the ceiling structure, and the roof panel was placed on the building unit. The ceiling height of the building unit can be set high.
[0016]
Roof panel is supported by the pillars of the building units because the roof panel is placed on a building unit, in order to mount the roof panel to the building unit, is installed between these roof panels and the building unit, Roof supports such as many kinds of bundles and trusses having different heights can be eliminated, and thus the cost for attaching the roof panel can be reduced.
