Description

Description: TECHNICAL FIELD The present invention relates to a draining structure for a joint between upper and lower floors in a unit house.

[Conventional technology]

As one of the rational architectural forms of houses, the building is divided into upper floor units and lower floor units and manufactured in a factory based on standard specifications. A unit house construction method for completing a house having an upper floor and a lower floor by the work of installing the above unit and installing the unit of the upper floor above it is becoming widespread.

In the above construction method, a draining structure as a measure for preventing rainwater intrusion from the outer wall portion of the joint between the unit on the lower floor and the unit on the upper floor is an important point, for example, Japanese Patent Publication No. 58-46618. And it is disclosed in Japanese Examined Patent Publication No. 62-7053, but it is not popular due to complicated construction.

FIG. 5 is a cross-sectional view showing an example of a conventional drainage structure for upper and lower floor joints in a unit house, and a conventional unit house upper and lower floor joint drainage structure will be described with reference to the same figure.

1 is a ceiling beam of the lower floor unit, and 1a is a stud of the lower floor unit, which is attached to the ceiling beam 1 and the floor beam (not shown) of the lower floor unit. 2 is an outer wall panel forming the outer wall of the lower floor, and 2a is an iron frame of the outer wall panel of the lower floor, which is attached to the stud 1a of the lower unit.

3 is a floor beam of the upper floor unit, and 3a is a stud of the upper floor unit, which is attached to the floor beam 3 and the ceiling beam (not shown) of the upper floor unit. 4 is an outer wall panel forming the outer wall of the upper floor, and 4a is an iron frame of the outer wall panel of the upper floor, which is attached to the stud 3a of the upper unit.

It should be noted that a gap is provided between the lower end of the upper floor outer wall panel 4 and the upper end of the lower floor outer wall panel 2 with a slight gap between the outer wall panel 2 and the upper floor so as to allow the outer wall dimension to have tolerance.

Reference numeral 5 denotes a sheet drainer, which is composed of a long sheet material having elasticity such as a rubber plate, and one edge in the longitudinal direction is between the floor beam 3 on the upper floor and the iron frame 4a of the outer wall panel 4 on the upper floor. The other edge covers the outer surface of the upper end portion of the outer wall panel 2 on the lower floor. Reference numeral 6 denotes a cover drainer that covers a gap at a joint portion between the upper floor outer wall panel 4 and the lower floor outer wall panel 2, and together with the sheet drainer 5, a floor beam is provided between the upper floor outer wall panel 4 and the lower floor outer wall panel 2. 3. It is designed to prevent rainwater from entering the part of the ceiling beam.

[Problems to be Solved by the Invention]

However, in the above-mentioned conventional example, the installation of the seat drainer 5 and the cover drainer 6 is a work at a high place at a construction site, so the construction is inconvenient and difficult, and additional work such as scaffolding and safety measures is also required. Especially, it is difficult to install the sheet drainer 5 at the corners, and the joint work of the sheet drainer 5 at the joint of the units on the same floor is difficult to obtain a complete draining effect. There was a problem that it cost a lot.

This invention was made in order to solve the above-mentioned problems of the prior art, eliminates the need for work at a high place on a construction site, and allows easy draining of the corners and joints of units on the same floor. It is an object of the present invention to provide a drainage structure for connecting a unit house upper and lower floors, which can obtain various drainage effects.

[Means for solving the problem]

Therefore, the unit house upper and lower floor joint draining structure according to the present invention is a unit house having an upper floor unit and a lower floor unit, and has a long length provided on one edge face in the longitudinal direction of a band-shaped draining member having elasticity. The groove is fitted into a band-shaped protrusion of a metal fitting fitted to the upper end of the lower unit outer wall, and is provided with a draining band projecting in a substantially vertical direction on the upper inside of the lower unit outer wall, and the draining band is the upper part. It is intended to achieve the above-mentioned object by a configuration characterized in that it is in contact with the inner side surface of the sheet material provided inside the outer wall of the floor unit.

[Action]

With the above configuration, the strip-shaped draining member has a long groove portion on one edge surface in the longitudinal direction, and a metal article having a band-shaped projection portion is fitted to the upper end of the lower unit outer wall, and the metal article. The long groove part of the draining member is fitted into the strip-shaped projection part,
An elastic draining strip that protrudes in a substantially vertical direction is formed on the upper inside of the outer wall of the lower floor unit, and contacts the inner surface of the sheet material provided inside the outer wall of the upper floor unit to drain water to the upper and lower floor joints of the unit house. The structure is such that the elasticity of the drainage strip and the sealing material are located above the hardware, and the hardware is fitted and attached to the outer wall of the lower unit to prevent rainwater from joining the upper and lower units. It has the effect of preventing invasion.

In addition, the processing of the draining member and the hardware and the attachment to the outer wall of the lower floor unit can be done in advance in the factory, eliminating the work of high places at the construction site, and joining the corners and the unit of the same floor Can be easily drained.
