Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof joint structure for a projecting-corner lower shed unit, and can be used for, for example, a flat balcony L-shaped shelter balcony surrounding a projecting corner of a unit type building.

[0002]

2. Description of the Related Art Conventionally, a unit construction method frequently used for building a building such as a house is to construct a unit-type building by arranging and stacking substantially box-shaped building units produced in a factory in advance at a construction site. In this unit construction method, a flat, substantially L-shaped slab unit that surrounds the projecting corner part of the unit type building also connects a plurality of shed units along two adjacent side faces through the projecting corner part of the unit type building. It is formed by installing. In this kind of Dekokumo Shigeya Balconi,
For the drainage from the downspout often installed in the corner of the building, reliable waterproofness is required.

By the way, when the lower shed unit is installed alone or when a plurality of lower shed units are connected in a straight line, the applicant of the present application has a handrail wall as a joint structure between the lower shed unit and the unit type building. We proposed a unit joint structure (Japanese Patent Application No. 4-120693). This is to form a rising part on the unit type building side of the lower unit and to arrange the outer wall of the unit type building on the rising part. Therefore, the shed unit and the unit-type building are joined to each other on a horizontal plane, and the waterproof treatment can be easily performed as compared with the case where they are joined on a vertical plane.

[0004]

However, by using the above-described joint structure of the unit with the handrail wall, a flat L-shaped projecting corner balcony surrounding a projecting corner of a unit type building is formed. In this case, the longitudinal end faces of the respective rising portions of the shed unit arranged along the side faces of the unit-type building are gathered in a rectangular shape at the projecting corner portions, and the portions become uneven. Therefore, there is a problem in that the work of attaching a waterproof sheet or the like to the protruding corners becomes complicated and reliable waterproofness cannot be obtained. An object of the present invention is to provide a waterproof joint structure for a shed unit in a projecting corner portion, which can reliably and easily obtain waterproofness of a shed unit arranged in a projecting corner portion of a unit-type building.

[0005]

A first invention according to the present invention is a first projecting corner lower shed unit and a second projecting unit which are arranged along two side faces adjacent to each other through a projecting corner of a unit type building. A waterproof joint structure for a corner shed unit, comprising a corner shed unit and a third projecting corner shed unit sandwiched between them and arranged in a projecting corner of the unit type building,
A waterproof rising portion is provided on the unit type building side of the first projecting corner lower house unit and the unit type building side of the third projecting corner lower house unit, and is waterproof on the unit type building side of the third projecting corner lower house unit. It is characterized by having a post.

A second aspect of the present invention is characterized in that the waterproof post is detachably provided on the third projecting corner lower shed unit. Furthermore, 3rd invention which concerns on this invention WHEREIN: The said waterproof post covers the rising part of the said 1st projecting corner part lower house unit and the said 2nd projecting corner part lower house unit, and the said 3rd projecting corner part lower house unit. It is characterized in that the first waterproof sheet and the second waterproof sheet which are extended toward are overlapped with the third waterproof sheet which covers the waterproof post.

[0007]

In the first aspect of the present invention as described above,
Since the waterproof post is provided on the unit type building side of the third projecting corner lower house unit, it is provided to the first projecting corner lower house unit and the second projecting corner lower house unit via the waterproof post. The waterproof waterfall will be continuous. Therefore, the waterproof sheet attached to the projecting corner portion is joined in a flat surface shape, which facilitates the work and ensures reliable waterproofness. Further, in the second aspect of the present invention, since the waterproof post is attachable to and detachable from the third projecting corner lower house unit, there is a risk of damage or the like when the projecting corner lower house unit is transported from the factory to the construction site. In addition, it is possible to selectively attach many types of waterproof posts having different shapes and the like. In the third invention according to the present invention,
Since the first waterproof sheet, the second waterproof sheet and the third waterproof sheet overlap each other, more reliable waterproofness can be obtained, and the above-mentioned object is achieved by these.
