DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a roof of a building constituted by combining a plurality of roof units.
For example, it can be used for the roof of a unit building.

[0002]

2. Description of the Related Art As shown in FIG. 5, in recent years, a living room or the like constituting a house in a factory is manufactured as a housing unit 51, and then these housing units 51 are transported to a construction site, and the housing unit
Unit housing designed to be constructed by combining 51 units
52 have been constructed. In such a unit house 52,
Normally, the roof 53 is also configured by combining a plurality of roof units 54A to 54C.

In the case of the gable roof 53 shown in the figure, the roof 53 is divided into three parts in parallel with the direction between beams, and these divided parts are divided into three parts.
The roof unit 54A at the center and the roof units 54B, 54C at both sides where 53A to 53C are further divided in parallel with the girder direction.
Consisting of And depending on the house, such a roof 53
It has been practiced to make effective use of the interior space as an attic.

[0004]

[Problems to be Solved by the Invention] Each roof unit 54A, 54
A bundle 57 for supporting a structural material such as a climbing beam 55 and a roofing material 56 such as a slate is provided at a predetermined position of B. Conventionally,
In a portion where the four roof units 54A to 54C in the roof 53 are adjacent to each other, four bundles 57 are arranged collectively.
Therefore, when trying to use the inside of the roof 53 as an attic, there is a problem that such a bundle 57 hinders a large space. In addition, since such a large space cannot be obtained, the use as an attic has been limited. Then, an object of the present invention is to provide a construction method of a roof of a building which can secure a large space inside the roof.

SUMMARY OF THE INVENTION The present invention relates to a method for constructing a roof of a building constituted by combining a plurality of roof units, wherein a plurality of bundles are located inside the roof. After preparing a roof unit as a temporary bundle that can remove the bundle and combining multiple roof units at the construction site, the climbing beams of the roof units adjacent in the inclination direction of the roof surface are joined via joining members, The temporary bundle is removed to form a large space extending between a plurality of roof units.

[0006] As described above, by removing the temporary bundle provided before the construction of the building after the construction, the bundle which has been obstructive in the past disappears, and a plurality of roof units are provided inside the roof.
It is possible to secure a large space spanning. In order to make the temporary bundle detachable, for example, the temporary bundle may be temporarily fixed to the structural material of the roof unit with bolts or the like. In addition, the structural members of adjacent roof units after the removal of the temporary bundle need to be joined together. For example, adjacent structural members may be joined via an appropriate joining member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for constructing a building roof according to an embodiment of the present invention will be described with reference to FIGS. In this embodiment, the building is a unit house 11, and the roof is a gable roof 12.

As shown in FIG. 1, in a factory, a plurality of roof units 13A to 13A constituting a roof 12 of a unit house 11 are provided.
Make 13C. The roof units 13A to 13C are
12 is divided into three parts parallel to the inter-beam direction, and these divided parts 12A to 12C are further divided into a central roof unit 13A and two side roof units 13B and 13C which are further divided in parallel to the girder direction. .

The roof unit 13A at the center has a roof unit frame 14A and a roofing material 15A such as a slate attached to the frame 14A. This roof unit frame 14A is
, Climbing beam 17A, ridge beam 18A, bundles 19A, 19B at both ends of ridge beam 18A
, Four bundles 21A to 21D at the corners. Of these four bundles 21A-21D, the roof
The bundle that will be located inside 12 is a removable temporary bundle
It is 22A. Such a temporary bundle 22A is composed of bundles 21A to 21A.
D can be removed by temporarily fixing it to the floor beam 16A and the climbing beam 17A with bolts or the like.

On the other hand, the roof units 13B and 13C on both sides are
Like the roof unit 13A at the center, the roof unit has roof unit frames 14B and 14C and roofing materials 15B and 15C attached to the frames 14B and 14C.
These roof unit frames 14B, 14C are connected to floor beams 16B, 16
C, climbing beams 17B and 17C, and two bundles 23A to 23D of corner portions are assembled. These two bundles 23A ~
Among the bundles 23D, bundles located inside the roof 12 are removable temporary bundles 22B and 22C. Such provisional bundles 22B and 22C have the same configuration as that of the roof unit 13A at the center and are removable.

In the factory, the roof unit 13
A plurality of housing units 24 are manufactured together with A to 13C. These housing units 24 are conventionally constructed by attaching an outer wall panel to a unit frame including columns, beams, and the like.

Next, as shown in FIG. 2, the roof units 13A to 13C and the housing unit 24 are transported to a construction site. Then, after combining the plurality of housing units 24 to form the first floor portion, the housing units 24 of the second floor portion are placed on these housing units 24. Subsequently, the roof 12 is made by placing the roof units 13A to 13C in combination on the housing unit 24 on the second floor. Next, as shown in FIG. 3, the temporary bundles 22A to 22C attached to the roof units 13A to 13C are removed to form a large space 25 in the roof 12 without bundles.

When removing the temporary bundles 22A to 22C, as shown in FIG. 4, the temporary bundles 22A to 22C are joined to the joining portions of the climbing beams 17A of the central roof unit 13A and the climbing beams 17B, 17C of the side roof units 13B, 13C. Apply member 26, and bolt 17 and nut 28
17C and 26C, the two climbing beams 17A to 17C adjacent to each other in the inclination direction of the roof surface are joined via the joining member 26. In each of the roof units 13A to 13C, the roofing material 15A to 15C above the joint between the two climbing beams 17A to 17C is used.
15C is provisionally secured to allow for on-site joining
It is fixed after joining work.

According to the above embodiment, a plurality of bundles 21A
21D, 23A to 23D, the roof units 13A to 13C were prepared as temporary bundles 22A to 22C from which the bundle to be located inside the roof 12 was detachable, and then a plurality of roof units 13A were formed at the building site. ~ 13C, the temporary bundle 22A ~ 22
C has been removed, eliminating the previously obstructed bundle and allowing the roof 12 to
A large space 25 can be secured.

Further, since the large space 25 is obtained inside the roof 12, the use of the inside of the roof 12 as an attic can be expanded. Further, the work of removing the temporary bundles 22A to 22C and joining the upper and lower climbing beams 17A to 17C can be performed by attaching and detaching bolts.

In the above embodiment, the building is a unit house 11, but the type of the building is arbitrary. For example, the building may be a steel framed structure. Although the roof 12 in the above embodiment is a gable roof, the type of the roof is arbitrary, and for example, a roof such as a ridge roof may be used.
Further, when it is desired to form a large space 25 only in a required portion in the roof 12, a temporary bundle may be provided only in a predetermined roof unit so that the space 25 can be formed.

[0017]

According to the roof construction method of the present invention, a large space can be secured inside the roof.
