[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure for a unit type building. More specifically, the present invention relates to a drainage structure of a unit-type building in which a plurality of outdoor units having a floor on which rainwater or the like is poured are arranged at right angles to form a balcony or an outer corridor.

[0002]

[Background Art] Even in a unit construction method in which various units manufactured in a factory are transported to a construction site and combined there to build a unit-type building, a plurality of balcony units and an outside corridor unit are provided around a building body composed of a plurality of room units. Are arranged adjacent to each other to form a balcony or an outer corridor. Conventionally, an outdoor unit such as a balcony unit or an outer corridor unit is provided with a structure for collecting rainwater and draining the rainwater because rainwater and the like pours down. For example, a conventional balcony unit is provided with a three-dimensional water gradient in which one corner of the side that is in contact with the building body is on the water side and gradually inclines downward toward the corner diagonally opposite to the corner.

[0003]

However, as shown in FIG. 6, the conventional balcony units 105A, 105B,
When 105C are arranged at right angles along the periphery of the building body 101, the arranged balcony units 105A to 105
As a result of the three-dimensional water gradient direction of C becoming the same direction, the floor 113 of the balcony units 105A to 105C
There is a problem that the step 106 is generated between A, 113B, and 113C. In other words, as shown in FIG. 7, the water side of the balcony unit 105C and the balcony unit 1
Since the water side of 05B is arranged adjacent to each other, the floor 113 of the adjacent balcony units 105C and 105B
There is a problem that a step 106 is generated between C and 113B.

Further, the balcony units 105A to 105
In order to make the floors 113A to 113C of C have a three-dimensional water gradient, it is necessary to prepare a plurality of types of floor base materials 114 having upper surfaces inclined at different gradients, as shown in FIG. Since it is necessary to arrange the upper surface of the floor base material 114 on the base frame 111 of the unit so as to match the three-dimensional water gradient, it takes time and time to process and install the floor base material 114 in forming the three-dimensional water gradient. There was a problem that it took.

Therefore, the applicant of the present invention has previously proposed a drainage structure for a unit type building which solves the above-mentioned conventional problems (Japanese Patent Application No. 6-310613). This is because in the drainage structure of a unit-type building in which the second and third balcony units are arranged at right angles with the first balcony unit sandwiched between them, the floors of the second and third balcony units are: A two-dimensional water gradient is formed in which the sides that are orthogonal to each other and that form the projecting corners of the right-angled array are inclined downward, and the floor of the first balcony unit has a line connecting the entry corners to the projecting corners of the right-angled array. The boundary is divided into two regions, and the respective regions are formed with the same water gradient as that of the second and third balcony units adjacent to each other.

By the way, in the case of such a configuration, the floor of the first balcony unit has a water gradient in which the sides forming the projecting corners incline downward, so that the water gradient causes the water side ( Rainwater gathers on the side that constitutes the projecting corner). Therefore, it is necessary to form a drainage groove in the floor of the first balcony unit for draining the rainwater collected under the water to the outside of the unit or to the adjacent balcony unit.
However, even if a drainage groove is formed on the floor of the first balcony unit to drain rainwater outside the unit or to an adjacent balcony unit, the structure is complicated and the cost is increased. The structure of the balconi unit is required to be simpler.

An object of the present invention is to solve such a conventional problem, and even when an outdoor unit such as a balcony is arranged adjacently to form a balcony or an outer corridor, a step is generated between the adjacent units. It is to provide a drainage structure for a unit-type building in which there is no need, and the water gradient of the unit can be easily created, and the structure of an outdoor unit arranged at a corner can be simplified.

[0008]

A drainage structure for a unit-type building according to the present invention has a first outdoor unit having a floor on which rainwater or the like is poured, and a right angle with the first outdoor unit sandwiched therebetween. In a drainage structure of a unit-type building that includes a second outdoor unit and a third outdoor unit that are arranged to form a balcony or an outer corridor, the floors of the second outdoor unit and the third outdoor unit are orthogonal to each other and A two-dimensional water gradient is formed in which the sides forming the projecting corners of the right angle array are inclined downward, and the floor of the first outdoor unit has two lines with a line connecting the entering corners and the projecting corners of the right angle array as a boundary. The area is divided into areas, and the inside edges of the areas incline downward from the line toward the corners located diagonally across the line, and the edges adjacent to the second and third outdoor units are Shaped to the same height level as these Characterized in that it is.

According to the drainage structure having the above structure, rainwater and the like that fall on the floors of the second and third outdoor units are drained toward the sides forming the projecting corners of the right angle array. In addition, rainwater that falls on the floor of the first outdoor unit is drained toward the floors of the second and third outdoor units according to the water gradient of each region divided by the line connecting the entrance corner and the exit corner. To be done. At this time, the water gradient of each area partitioned within the floor of the first outdoor unit is inclined downward from the line toward the corners located diagonally across the line, and
Since the edges adjacent to the second and third outdoor units are formed at the same height level as these, there is no step between the outdoor units. Also, since the second and third outdoor units may have a two-dimensional water gradient, they can be manufactured more easily than the conventional three-dimensional water gradient, and the first outdoor unit does not need a drainage groove. Therefore, the structure can be simplified.

In the above structure, the line dividing the floor of the first outdoor unit into two areas is preferably formed at the same height level from the entry corner to the exit corner of the right angle array.
In this way, in each area, a two-dimensional water gradient can be formed inclining downward from the line to the diagonally located corners of the line, so that the floor of the first outdoor unit The water gradient can be simplified.

Further, the line that divides the floor of the first outdoor unit into two areas is set at the same height level from the entry corner to the exit corner, and the floor of the first outdoor unit is moved from the entry corner to the exit corner. It is preferably composed of triangular floorboards respectively arranged in two regions divided by the connecting line. By doing so, the number of parts can be reduced and the waterproof treatment at the joint can be simplified.
