BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit type roof, and can be used for forming a roof portion of a unit type building constructed by joining a plurality of roof units.

[0002]

2. Description of the Related Art Conventionally, in order to construct a building such as a house, a unit construction method in which a plurality of units manufactured in advance in a factory are joined on site to construct a building is often used. Although there are various methods for forming the roof portion in this unit construction method, the unit type roof is often composed of a plurality of roof units due to dimensional restrictions and the like. by the way,
When the unit type roof is composed of a plurality of roof units, the waterproof performance of the joint portion between the roof units or the simplicity of waterproofing work becomes a problem.

For example, FIG. 6 shows a schematic structure of a conventional unit type roof. In the figure, the unit roof 80 is composed of an upper unit 81 including a ridge portion and a lower unit 82 including an eaves portion. The sloped surface 83 of the upper unit 81 and the sloped surface 84 of the lower unit 82 are in a straight line, and the joint portion 85 between the upper unit 81 and the lower unit 82 is a flat joint.

In such a flat joint, the seam portion
There is a problem in that the waterproof treatment of 85 rises up against the roof slopes 83 and 84, impairing the appearance. When the roof tile installation work is performed to hide the waterproof treatment of the seam portion 85, the work is an insertion work because of the flat joining, which is troublesome.

Therefore, the present applicant has proposed a unit type roof as shown in FIG. 5 which ensures the waterproof performance and does not impair the appearance due to the waterproof treatment (Japanese Patent Laid-Open No. 3-22).
4941, JP-A-3-224942, etc.).

In FIG. 5, a unit type roof 90 includes an upper unit 91 including a ridge portion and a lower unit including an eaves portion.
It is composed of 92 and. The upper unit 91 and the lower unit 92 are joined at a joint surface 93.
The height of the upper unit 91 is higher than that of the lower unit 92 by a predetermined height. Therefore, the sloped surface of the unit type roof 90 has a step shape, and the vertical step surface 94 is exposed. The joint portion 96 between the step surface 94 and the roof slope 95 of the lower unit 92 is waterproofed to prevent rainwater and the like from entering.

According to such a unit type roof 90 of the conventional example, since the step surface 94 is originally formed on the sloped surface of the roof, the waterproof processing can be performed by using the step surface 94. It is possible to eliminate the inconvenience of spoiling the appearance even if the seam portion 96 of the sloped surface rises due to the waterproof treatment. Further, since it is not a flat joint like the seam portion 85, it is possible to eliminate the inconvenience that the roof tile installation work for hiding the waterproof treatment of the seam portion 96 becomes an insertion work.

[0008]

However, in such a conventional unit-type roof 90, the joint portion 96 is exposed on the upper surface side, and the structure is such that rainwater and the like easily enter. However, there is a problem that it is difficult to secure waterproof performance and complicated waterproof construction is required. Further, since the step surface 94 is formed in the vertical direction, when this portion is used as, for example, a ventilation port, there is a problem that rainwater may invade from the ventilation port or the like and wind may blow in.

An object of the present invention is to provide a unit type roof which can easily ensure waterproof performance and can be provided with a ventilation port or the like in which rainwater does not invade or wind blows in.

[0010]

A unit type roof of the present invention has an upper unit including a ridge portion and a lower unit including an eaves portion, and an end portion of the upper unit includes the upper unit and the lower unit. It is characterized in that it protrudes in the horizontal direction from the joining portion of, and the lower surface of the protruding end portion is a substantially horizontal surface. Here, it is preferable that the substantially horizontal surface is an auxiliary function surface having a predetermined function such as a ventilation port.

[0011]

In the present invention, the end of the upper unit projects horizontally from the joint between the upper unit and the lower unit, and the lower surface of the projecting end is a substantially horizontal plane. Since the structure is such that rainwater or the like does not easily invade, waterproof performance can be easily ensured, and complicated waterproof construction can be eliminated. In addition, since the lower surface of the protruding end is a substantially horizontal surface as described above, it becomes possible to prevent rainwater from entering and blowing of wind when installing a ventilation port or the like on this surface. The above object is achieved.

The molding sealings 22 and 26 are rubber-like sealing members, and the molding sealing 22 and the bonding surface 14 are in contact with each other, and the molding sealing 26 is in contact with the bonding surface 13 to seal rainwater and the like. Has been done.

The end of the upper unit 11 projects horizontally outward from the joining surface 14, and after joining the upper unit 11 and the lower unit 12, the end of the upper unit 11 projects from the lower unit 12. Is configured to. An auxiliary function surface 30 is formed on the lower surface of the portion of the upper unit 11 protruding from the lower unit 12. Auxiliary function surface 30
Is a downward horizontal surface, and the auxiliary function surface 30 is provided with a ventilation port 31.

In this embodiment, the unit type roof 10 is constructed as follows. That is, first, the molding ceilings 22 and 26 are installed in advance on the joint surfaces 13 and 14, respectively, in a factory. Next, the lower unit 12 is installed at a predetermined position on the upper side of a living room unit or the like (not shown) in the field.

Thereafter, the upper unit 11 is hung down while being kept horizontal by a crane, and the joint surface 13 of the lower unit 12 and the joint surface 14 of the upper unit 11 are brought into contact with each other. At this time, the upper unit 11 is guided by the guide pins 21 and the guide holes 25 and is lowered to a predetermined position. At the same time, the molded sealings 22 and 26 are crushed by the weight of the upper unit 11 to be in a sealed state. Finally, tighten the upper unit 11 and the lower unit 12 with the bolt 23,
This completes the construction of the unit roof 10.

According to this embodiment, the end of the upper unit 11 is projected from the lower unit 12 so that rainwater or the like is unlikely to enter, that is, rainwater or the like of the upper unit 11 does not enter. After traveling down the sloped surface, it hardly drops vertically and wraps around the joint surfaces 13 and 14, so that the waterproof effect can be obtained even with a simple structure.

Further, the end portion of the upper unit 11 projects in the horizontal direction from the joining portion between the upper unit 11 and the lower unit 12, and the auxiliary function surface 30 which is a downward horizontal surface formed on the lower surface of the projecting portion. Since the ventilation port 31 is provided, it is possible to prevent rainwater from entering the ventilation port 31 and blowing of wind.
