Description

[Detailed description of the invention] This invention relates to the connecting structure of a unit house.

Although unit houses are often used alone, they can also be used by connecting two or more units together, for example, in JP-A-56-
It may also be configured and used as shown in Publication No. 85043.

When two unit houses are connected in parallel, unit houses 1 and 2 are connected as shown in Figure 1.
If the connecting portion 3 is configured at a high point on the roof portion, rainwater will flow along the downward slope of the roof portion as shown by the arrow, and there is no need to provide a rain gutter in the connecting portion 3. (See Figure 4 in Japanese Patent Application Laid-open No. 56-85043,
The configuration shown in FIG. 6 is like this. ) Also, as shown in Fig. 2, two or more unit houses 4, 5, 6, 7 are connected in parallel at the connecting parts 8, 9, 10, and the connecting parts 8, 10 are used as high places on the roof. If the connecting portion 9 is located at a low point on the roof, rainwater will flow along the downward slope of the roof as shown by the arrow. Since rainwater falling on the unit houses 5 and 6 flows to the connecting part 9, it is necessary to provide a rain gutter here. However, when a rain gutter is provided at the connecting portion, there remain problems as shown in the conventional example shown in FIG.

Figure 3 shows a rain gutter installed at the connecting part of unit houses 12 and 13, and the area around the opening formed so that residents can come and go from one side to the other is connected with an appropriate member (not shown). , rain gutters are installed above it. The structure of this rain gutter is
Eaves 12a, 13a of unit houses 12, 13
Drain gutters 15 and 16 are fixed to the walls 12b and 13b directly below them along the
is now being established.

When the unit houses 12 and 13 are connected, a gap B is formed between the water drains 15 and 16. This gap B is provided so that when connecting the unit houses 12 and 13, there is no problem even if there is some error in the distance between the wall portions 12b and 13b.

The rainwater is first received by the draining gutters 15 and 16, and then is allowed to fall from the gap B to the rainwater gutter 17 located below.
It is designed to receive water and drain water.

In this configuration, the rain gutter 17 has wall portions 12b and 1
3b, so it is fixed only to one wall portion 12b or 13b. Therefore, when connecting, it is necessary to combine a unit house that has a rain gutter 17 (for example, 12) and a unit house that does not (for example, 13). Items that do not have both cannot be combined. In other words, there are significant restrictions on the selection of unit houses to be connected.

The present invention has been devised to solve the above-mentioned difficulties. Utility Publication 57-
There is also a device as shown in Publication No. 12098, but the present device has a simpler structure to form a rain gutter, and is configured to absorb any dimensional error between the two connected unit houses. This is what I did.

That is, the drain gutters are respectively fixed along the corresponding eave portions of the connecting portions. The drain gutter is formed such that the respective hanging walls face each other with a suitable gap when connected, and hook portions projecting in opposite directions are formed on the lower edges of the hanging walls. Then, a rain gutter having a substantially closed cross-section shape having a longitudinal slit portion on the upper surface is provided, and the slit portion is fitted onto the outside of the opposing hanging wall, and both edges of the slit portion are locked to the hook portion to form the rain gutter. It is designed to hang.

The structure of the present invention will be explained below using the embodiment shown in FIGS. 4 and 5.

In the case where unit houses 21 and 22 are connected in parallel, the corresponding eave portions 21a and 2 of the connecting portion
Drain troughs 23 and 24 are fixed along 2a, respectively. That is, as shown in FIG. 5, in the unit house 21, the drain gutter 23 is located above the opening 21c of the connecting portion. (Similarly, in the unit house 22, the drain gutter 24 is located above the opening of the connection part.) The drain gutter 23, 24 is connected to the hanging walls 23a, 2, respectively.
4a, and when the unit houses 21 and 22 are connected, a gap D is formed between the hanging walls 23a and 24a. When connecting the unit houses 21 and 22, this gap D is
This is provided so that there is no problem even if there is an error in the distance between 1b and 22b. and hanging wall 2
Hook portions 23b are provided on the lower edges of 3a and 24a, respectively.
24b is provided. The hook portions 23b, 24b are formed so as to project to opposite sides when the unit houses 21, 22 are connected.

Further, a rain gutter 27 having a substantially closed cross-section shape and having a longitudinal slit portion 27a on the upper surface is provided. The rain gutter 27 is made of metal, plastic, or the like, and is connected to the drain gutter 23, 24 to receive rainwater. That is, in a state where the unit houses 21 and 22 are connected (the connection is made separately using an appropriate member), the hanging wall 23 facing the slit portion 27a

The rain gutter 27 is arranged in a lateral direction (eaves 21a, 22
The gap E between the rain gutter 27 and the wall part 21b, the gap E between the rain gutter 27 and the wall part 2
2b, the edge 27b of the slit portion 27a
Gap G between the shoulder portion 23d of the drain gutter 23, and the edge 27c of the slit portion 27a and the shoulder portion 24d of the drain gutter 24.
A gap H is appropriately provided between the rain gutter 27 and the rain gutter 27 so that the rain gutter 27 can be easily assembled.

With this configuration, rainwater flowing into the joint between the unit houses 21 and 22 is directed to the drain gutter 23.
The water falls onto the shoulder 23d of the drain gutter 24 and the shoulder 24d of the drain gutter 24, flows into the gutter 27 through the gap D, flows in the longitudinal direction, and is drained.

As mentioned above, the present invention is a system in which unit houses are connected in parallel, and drain gutters that face each other are fixed along the corresponding eaves of the connecting parts, and rain gutters are suspended from the drain gutters. Therefore, it is possible to prevent rainwater from entering the opening of the connecting portion with an extremely simple structure. It is possible to absorb the dimensional error that occurs between the two walls when connecting, and when installing on uneven ground, the inclination error on the connecting surface of the parallel unit houses 21 and 22 as shown in Fig. 6 can be absorbed. This has various advantages, such as being able to absorb this by the gaps E, F, G, and H even if it occurs.
