Description

[0001]
BACKGROUND OF THE INVENTION
The present invention includes a building body configured by combining a plurality of building units, and a roof configured by arranging a plurality of roof structures including a roofing material on the top of the building body according to the building units. It relates to the roof structure of the unit type building.
[0002]
[Background]
Conventionally, a unit type building formed by combining a plurality of building units manufactured in a factory at a construction site has been used.
A building unit is usually composed of columns standing at the four corners, and ceiling beams and floor beams that connect the upper and lower ends of these columns to each other, and have long and short sides with different lengths. It has a rectangular parallelepiped frame having a rectangular planar shape. This frame is preinstalled with floor materials, wall materials, and other necessary equipment members at the factory. Under the present circumstances, in order to improve the rigidity of a building unit, the brace which is the reinforcement member laid over the braces is provided in the upper surface of the said building unit.
According to such a unit-type building, since flooring materials and the like are previously attached to the building unit, the unit-type building can be shortened for a short period of time by placing the building unit at a predetermined position by a lifting machine or the like at the construction site. Therefore, there is an advantage that the construction period at the construction site can be greatly shortened.
[0003]
By the way, a balconi may be formed on the outdoor part of the building, and in a unit type building, a balconi unit may be formed by protruding a cantilevered balconi unit on the outer wall surface of the building. Since it is a cantilever support, the installation work etc. in a construction site will become complicated.
For this reason, a balconi may be formed by using a building unit with an outdoor floor (inner balcony unit) in which a part of the floor of the building unit is an outdoor floor such as balconi (Japanese Patent Application No. 11-1897, etc.). reference).
[0004]
Here, a brace may be erected on the upper surface of the inner balcony unit as in the case of the building unit.
However, when a roof is provided immediately above the inner balcony unit, depending on the structure of the roof, braces may not be erected on the inner balcony unit. In this case, a flat square frame-like panel having braces laid in a brace is interposed between the roof and the inner balcony unit, thereby ensuring the rigidity of the inner balcony unit.
[0005]
[Problems to be solved by the invention]
However, when a panel is used to ensure the rigidity of the inner balcony unit, there is a problem that the number of parts increases and the assembling work becomes complicated in assembling the unit type building.
Such a problem is not limited to the inner balcony unit. For example, there is a similar problem in a building unit or the like in which a roof is provided directly above and an air conditioning system is installed on the upper part and braces cannot be installed.
[0006]
An object of the present invention is to provide a roof structure of a unit type building that can be easily assembled while ensuring the rigidity of the building unit.
[0007]
[Means for Solving the Problems]
The present invention will be described with reference to the drawings. A building body 3 configured by combining a plurality of building units 10 and 20 having a substantially rectangular parallelepiped frame 11 from columns 12 and beams 13 and 14, and the building body 3 The roof structure of the unit type building 1 having a roof 4 configured by arranging a roof structure 4A including a roof material in accordance with the building units 10 and 20 at an upper portion of the roof structure, 4A is provided with a structural surface reinforcing portion that reinforces the horizontal structural surface of the building unit 20 on the lower surface, and the building unit 20 has a region in which at least a part of the upper surface is partitioned into a rectangular shape, reinforcing portion includes a brace 44 which is laid diagonally in the rectangular area of the building units 20B, is configured to include a channel member 45, the roof structure 4A includes a plurality of roof panels 41, these shops A plurality of bundles 42 supporting the ridge side of the panel 41, and a plurality of supporting members 43A, 43B for supporting the eaves side of the roof panel 41, the plurality of beams 42 are ridge side and eaves of the building units 20B Among the beams 13 facing each other on the side , the support members 43A and 43B are installed at both ends and the middle of the eaves-side beam 13 of the building unit 20B. The channel member 45 connects the opposed bundle 42 and the supporting members 43A and 43B in the middle of the opposed beams 13 of the building unit 20B, and the braces 44 are arranged diagonally. The support members 43A and 43B are connected to each other.
Here, the roof structure which comprises a roof is normally joined by joining members, such as a volt | bolt and a nut, to the upper part of the building unit which faces the said roof structure among some building units. According to the present invention, the horizontal structural surface of the building unit can be reinforced by providing the structural surface reinforcing portion on the roof structure. There is no need to provide a panel having a reinforcing member, and the building unit can be easily reinforced, and the panel installation work is not necessary. This facilitates the assembly work of the unit type building while ensuring the rigidity of the building unit.
[0008]
In the above, in the present invention, if the structural reinforcement is a brace, it is possible to ensure the rigidity of the building unit simply by constructing the brace diagonally in a rectangular region along the upper surface of the building unit. Therefore, also from this point, it is possible to easily assemble the unit type building while ensuring the rigidity of the building unit. Furthermore, if the braces are provided at the braces, the rigidity of the building unit can be further improved.
[0009]
Further, the building unit 20B is preferably a building unit with an outdoor floor in which an outdoor floor exposed outdoors and an indoor floor disposed indoors are provided inside, and a part of the upper surface is opened. . In this way, if the structure in which the structural reinforcement is provided on the roof structure is applied to the building unit with an outdoor floor, the rigidity of the building unit with the outdoor floor can be easily secured regardless of the structure of the roof. It becomes.
