BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof unit used for a projecting roof, and can be used for a unit type building in which various units such as a roof unit are manufactured in advance in a factory and these are assembled and constructed on site.

[0002]

BACKGROUND ART Conventionally, for buildings such as houses, unit type buildings have been constructed in order to shorten the construction period and improve economy. There are various types of such unit-type buildings. FIG. 2 shows a unit-type building 90 having an overhanging roof, which is an example of such a unit-type building. The unit-type building 90 includes a bookstore unit 91 that forms a so-called bookstore (honoku) portion, and a shedhouse unit 94 that is provided so as to project outward from an outer wall 92 of the bookstore unit 91. It is configured to include. Above the lower unit 94 is a bookstore unit.
A roof unit 93 forming a one-way overhanging roof is provided so as to contact the outer wall 92 of 91. On the outer wall 92 above the joint portion 95 between the outer wall 92 and the sloped surface 97 of the roof unit 93,
An opening 96 such as a window is provided. In such a unit-type building 90, in order to prevent rainwater and the like from entering, the joint portion 95 is waterproofed after being assembled on site.

[0003]

However, in the unit type building 90 having such a conventional overhang roof,
Since the outer wall 92 and the sloped surface 97 of the roof unit 93 are not flat, the waterproof structure of these joint portions 95 becomes complicated. Further, there is a problem in that the complex work on site increases, and therefore the feature of the unit-type building that only requires simple assembly cannot be fully utilized at the site.

On the other hand, in the unit type building 90, the joint portion 95
There is a problem in that the opening 96 cannot be made large due to the existence of. In other words, in the case of the south surface, there is a strong demand for making the opening 96 larger, but due to the existence of the joint portion 95, it cannot be extended or expanded downward, and such a demand cannot be realized. It was In particular, since the joint portion 95 is a waterproof joint having a complicated accommodation as described above, a part of the outer wall 92 in the vicinity is exclusively occupied by the waterproof treatment, which results in the extension of the opening 96 downward. , The restrictions on expansion were even greater.

Further, since the window or the like which is the opening 96 is often a standard product, it is not possible to freely set the dimensions, and therefore, there is a limit to what can be used due to the above-mentioned restriction by the joint portion 95, and the installation is not possible. If you choose what is possible, you can open 96 more
Had the problem of becoming small.

It is an object of the present invention to provide a roof unit which can be easily waterproofed on site and can have a large opening such as a window on the outer wall.

SUMMARY OF THE INVENTION The present invention is a roof unit used for an overhanging roof projecting outside the outer wall of a living room, wherein a predetermined distance is provided between the roof surface forming the upper surface of the overhanging roof and the outer wall. And a projecting wall projecting outward, and an edge of the roof surface is joined to a side surface of the projecting wall. Here, it is preferable that the projecting wall is formed using a balcony, a flower shelf, or the like.

[0008]

In the present invention as described above, the edge of the roof surface of the roof unit and the side surface of the overhanging wall are joined at the factory. At this time, the joint portion is waterproofed if necessary. Then, the roof unit having the projecting wall is arranged outside the outer wall of the bookstore part of the building to form a projecting roof which is the roof of the lower part of the building. For this reason,
The roof unit and the outer wall side need only be joined to the inside (outer wall side) of the overhanging wall, and the inconvenience of performing complex joint waterproof joining between the mutually intersecting roof surface and outer wall in the field construction as in the past Can be solved.

Further, since the roof surface of the roof unit is not directly joined to the outer wall of the bookstore portion but is joined to the overhanging wall, it is necessary to secure the outer wall surface for providing the large opening as described above. Various problems can be solved, and the above-mentioned object is achieved by these.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a unit-type building 10 includes a bookstore unit 11 forming a two-story bookstore portion and a shedhouse unit 13 forming a shed portion provided so as to project outward from an outer wall 12 of the bookstore unit 11. It is configured to include and. On the upper side of the shed unit 13, a roof unit 21 and an eaves unit 22 are installed, and these form a one-way overhanging roof 20. In the roof unit 21, the slope surface 24 is an upper part of the slope surface 23 of the overhang roof 20, and in the eaves unit 22, the slope surface 25 is the slope surface of the overhang roof 20.
It is arranged to be the lower part of 23.

The roof unit 21 has a balcony 30 at the upper end of its slope 24. The handrail wall of the balcony 30 forms an overhanging wall 31 having a height dimension H at a predetermined interval T from the outer wall 12 of the bookstore unit 11 on the second floor when the roof unit 21 is installed. .

The joint 26 between the upper edge of the sloped surface 24 of the roof unit 21 and the side surface of the overhanging wall 31 of the balcony 30 is waterproofed. Further, the joint portion 27 between the balcony 30 and the outer wall 12 of the bookstore unit 11 on the second floor is subjected to the same waterproof treatment as the joint portion of the conventional balcony unit already proposed by the applicant (special feature). Wish 4-
(See Japanese Patent No. 120693). Outer wall of bookstore unit 11 on the second floor
A door 40, which is an opening for opening to the balcony 30, is provided on the 12, and the lower edge 41 of the door 40 is an overhanging roof.
An imaginary intersection where the extension line of 20 slopes 23 and the outer wall 12 intersect
It is located below 28.

In this embodiment as described above, a unit type building is constructed as follows. First, various units such as a roof unit 21 having a balcony 30 and other units such as a bookstore unit 11, an eaves unit 22 and a shed unit 13 are manufactured in a factory. At this time, the slope surface of the roof unit 21
The joint between the upper edge of 24 and the overhanging wall 31 of the balcony 30
26 is waterproofed in advance.

Next, the unit type building 10 is constructed by assembling these various units on site. At this time, the joint portion 27 between the balcony 30 provided on the roof unit 21 and the outer wall 12 of the bookstore unit 11 on the second floor is subjected to the same waterproof treatment as the joint portion of the conventional balcony unit.
