Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drainage structure for a house, and more particularly to a drainage structure for a roof of an outside corridor in an apartment complex or the like.

[Prior Art] In housing complexes such as apartments, there are cases where a roof is provided above the top floor of an outside hallway. Conventionally, in such cases, draining hardware was installed at the eaves to prevent water from entering the building from the eaves, and rainwater dripping from the draining hardware and flowing into the eaves due to the slope of the roof. Eaves gutters were installed to catch rainwater. A vertical gutter was connected to the twenty eaves gutter via a gutter, and the rainwater that flowed from the eaves gutter through the gutter and into the gutter was drained from the lower end of the gutter.

[Problems to be Solved by the Invention] However, in the above-mentioned drainage structure, the eaves gutter and the down gutter are attached to the building by the eave gutter holder and the down gutter holder, respectively. Since drain fittings, elbows, etc. are provided at the connecting portions of the gutter and the connecting portions between the gutter and the downpipe, the number of parts increases, resulting in a problem of high construction costs.

In addition, in the above-mentioned drainage structure, when installing the eaves gutter, it is necessary to install a water system and carry out construction work to center the eaves gutter receiver, and the installation of the eaves gutter must be carried out. At the time of installation, in order to install the vertical gutter straight, it is necessary to stretch threads and perform construction work to install the vertical gutter, which is very troublesome.

Furthermore, in the above-mentioned drainage structure, since the eaves gutters and vertical gutters are installed exposed, there is a problem in that the exterior design of the building loses its cohesiveness and the aesthetic appearance of the building is impaired.

This invention was made to solve the above problems, and it is possible to reduce the number of parts, and has good workability.
The main objective is to provide a drainage structure for the roof of an exterior corridor that does not impair the beauty of the building.

[Means for solving the problem] In the roof drainage structure installed above the top floor of the external hallway, water on the roof is received in a water collector installed outside the upper end of the hollow hallway pillar. An eaves gutter is installed horizontally for the purpose of the hallway, and an inlet is drilled near the upper end of the hallway pillar to introduce the water collected in the water collector into the hallway. Water on the roof of the outside hallway can be drained by drilling an outlet at the bottom of the pillar to drain water flowing down inside the hallway.

[Operation] According to the above means, both ends of the pillars are supported by the water collectors at the upper ends of the adjacent corridor pillars, so that the eaves gutter is horizontally suspended between the water collectors. Not only is there no need for gutter holders, there is also no need to line up the water system and center the eaves gutters. Furthermore, since hollow hallway pillars are used as the downspouts, there is no need for downpipe supports, conventional downspout and gutter, elbows, etc. Therefore, the number of parts can be reduced and the installation work can be simplified.

Further, according to the above means, since a gutter and a downpipe are not required, the aesthetic appearance of the building is not impaired, and a sense of luxury is created in the exterior of the building.

[Example] An example of an M-root drainage structure for an external hallway according to the present invention will be described based on the drawings.

FIG. 1 shows a partial cross section of an exterior hallway in a housing complex such as an apartment. In the figure, reference numeral 1 denotes a hollow hallway pillar, and a beam 3 is mounted on the upper end of the pillar through an L-shaped angle 2.

The eaves of the roof 4 of the outside corridor is located on this beam 3. In addition, there is an inlet 1 near the top end and bottom of the hallway pillar l.
A and an outlet 1b are bored, respectively, and a water collector 5 is attached to the upper end of the hallway pillar 1 so as to surround the inlet 1a. An eaves gutter 6 extends along the eaves between the hallway pillar I and the adjacent hallway pillar 1, and the end of the eaves gutter 6 is connected to the water collector 5. has been done.

Therefore, rainwater that flows to the eaves due to the slope of the roof 4 flows into the eaves gutter 6. The water that has flowed into the eaves gutter 6 drips into the water collector 5 from the end of the eaves gutter 6, and the water flows into the water collector 5.
It flows into the hallway pillar 1 through the inlet 1a that opens inward. The water that has flowed down inside the hallway pillar 1 flows out of the hallway pillar 1 from the outlet 1b, and drainage is completed.

Next, each member used in the above drainage structure will be specifically explained.

As shown in FIG. 2, the hallway pillar 1 is made of steel and has a rectangular planar cross section, and supports the floor and roof 4 of each floor of the outside hallway. The inner wall of this hallway pillar 1 is subjected to anti-rust treatment,
Even if water flows inside the hallway pillar 1, the inner wall thereof is not corroded.

The water collector 5 is made of steel and has a cylindrical shape with a bottom, and a connecting portion 51 provided at the lower part of the water collector 5 is welded to the hallway pillar 1, for example. This connecting portion 51 is provided with a flow channel 52 for guiding water accumulated in the water collector 5 to the inlet 1a of the hallway pillar 1. In addition, the side wall 5 of the water collector 5
3 is provided with two notches 54 into which the ends of the eaves gutters 6 are inserted without gaps. These two notches 54
The upper part of the flow channel 52 sandwiched by the angle 54 is a fixing part 55 for attaching the eaves gutter 6, and for example, four bolt holes through which bolts for attaching the eaves gutter 6 pass are bored.

The eaves gutter 6 is made of aluminum light alloy, for example, and as shown in FIG. The upper part of the side wall 63 is bent to form a slope between the roof slope and the road.

Further, the length of the building-side side wall 63 of the eaves gutter 6 is longer than the outer side wall 64 of the eaves gutter 6. Specifically, the length of the building side wall 63 is made slightly shorter than the distance between the centers of the adjacent corridor columns 1.1. On the other hand, the length of the outer side wall 64 is made slightly longer than the distance between the opposing notches 54, 54 of the water collectors 5, 5 attached to the upper ends of the adjacent hallway pillars 1, 1. Both end portions of the building side wall 63 are provided with attachment portions 65 and 65 that are attached to the fixed portion 55 of the water collector 5. Two bolt holes are formed in the mounting portion 65 in the vertical direction so as to match the positions of the two vertical bolt holes among the four bottle holes formed in the fixing portion 55. has been done.

Next, the construction procedure for the above drainage structure will be explained with reference to FIGS. 1 and 4.

First, the connection part 51 of the water collector 5 is attached to the hallway pillar l in which the inlet 1a and the outlet 1b are bored so as to surround the inlet 1a.
For example, by welding. Then, as in the past, the framework of the outside hallway is assembled, and the hallway pillars 1 to which the water collectors 5 are welded are attached. A beam 3 is attached to the upper end of the hallway pillar 1 via an angle 2. Then, the roof base material 41 is attached so that the beam 3 supports the outer tip of the roof base material 41, which is the base of the roof 4, that is, the eaves.

At this time, the eaves of the roof base material 41 should not protrude beyond the outer surface of the angle 2.

Next, a water collector 5 attached to the adjacent hallway pillar 1.1
, 5 at each of the notches 54, 54 at both ends of the eaves gutter 6.
5.65 is placed on the rack. And, as shown in Figure 4,
Insert the bolts through each bolt hole of the mounting part 65, and attach the water collector 5.
The fixing part 55 is inserted through a bolt hole and is screwed into a nut fixed to the angle 2 in advance. At this time, eave gutter 6
As described above, the fixing piece 62 is bent to form a slope between the roof slope and the roadway, so the fixing piece 62 is attached to the roof base material 41. Then, the roof material 42 is attached on the fixing piece 62 and the roof base material 41, and the roof 4 is completed. By attaching the eaves gutter 6 in this way, the fixed piece 62 of the eaves gutter 6 and the building side wall 63 will function as a draining hardware conventionally attached to the eaves, preventing water from penetrating into the building from the eaves. It prevents you from doing it.

According to the above embodiment, the following effects can be obtained.

That is, the water collector 5 adjacent to the mounting part 65, 65 of the eaves gutter 6,
By mounting the eaves gutter 6 on the water collectors 5, the eaves gutter 6 is suspended horizontally between the respective water collectors 5, 5, which not only eliminates the need for eaves gutter receivers but also simplifies the installation of the eaves gutter. Moreover, since the hollow hallway pillar 1 is used as a vertical gutter, there is no need to perform construction work to install a conventional vertical gutter. Therefore, reducing the number of parts and installing the gutter can simplify construction work and reduce construction costs.

Further, since the fixing piece 62 of the eaves gutter 6 and the building side wall 63 function as conventional draining hardware, there is no need to attach conventional draining hardware. Therefore, construction costs can be reduced.

Furthermore, a fixing piece 62 integrally molded with the eaves gutter part 61 of the eaves gutter 6
Since it is fixed between the roof base material 41 and the roof material 42, there is no gap between the roof 4 and the eaves gutter section 61. Therefore, even in the case of strong wind and rain, all the rainwater that has flowed to the eaves due to the roof slope will flow into the eaves gutter part 6], and water can be prevented from flooding into the needles of the outside corridor.

Furthermore, since the attachment parts 65, 65 of the eaves gutter 6 are bolted to the angle 2 via the fixing part 55 of the water collector 5, the eaves gutter 6 can be firmly attached to the eaves. Therefore, since the depth of the eaves gutter section 61 can be increased, it is possible to prevent water from overflowing from the eaves gutter section 61 even when there is a large amount of rain.

Further, by making the eaves gutter section 61 deep, even if a certain amount of water is stored in the eaves gutter section 61, it will not overflow. Therefore, if water accumulates in the eaves gutter section 61, the accumulated water will naturally flow down from both ends of the eave gutter section 61 into the water collector 5, so it is necessary to provide a water gradient in the eaves gutter section 61. do not have.

Furthermore, the eaves gutters 6, which look like decorative curtain boards, make the eaves of the roof of the exterior hallway look luxurious, while the water collectors 5 serve as an accent to the building's exterior, enhancing the design of the building's exterior. . Therefore, a sense of luxury is created.

Furthermore, the water that has flowed into the eaves gutter 6 passes through the water collector 5, flows down inside the hallway pillar 1, and is drained, so that the service gutter and vertical gutter become unnecessary. Therefore, gutters are not disposed along the pillars or outer walls of the building, so the aesthetic appearance of the building is not impaired.

Although the invention made by the present inventor has been specifically explained above based on Examples, it goes without saying that the present invention is not limited to the above Examples and can be modified in various ways without departing from the gist thereof. Nor.

For example, in the above embodiment, the fixed portion 55 of the water collector 5
The eaves gutter 6 is attached to the eaves by bolting the attachment part 65.65 of the eaves gutter 6 to the angle 2 through the bolts, but the invention is not limited to this. The eaves gutter 6 may be attached to the eaves by fixing it to the roof base material 41.

Further, in the above embodiment, the water collector 5 is welded to the upper end of the hallway pillar l, but the invention is not limited to this, and the water collector 5 may be attached to the hallway pillar 1 by bolting. good.

[Effects of the Invention] The effects obtained by typical inventions disclosed in this application are briefly explained below.

In other words, in a roof drainage structure installed above the top floor of an exterior hallway, an eaves gutter is used to collect water on the roof into a water collector installed outside the upper end of the hollow hallway pillar. is suspended horizontally, an inlet opening toward the inside of the water collector is drilled near the upper end of the corridor column, and an outlet is drilled at the bottom of the corridor column, so that the outer corridor Since the water on the roof of the building is drained away, there is no need to install a separate vertical gutter. Therefore, reducing the number of parts and installing the gutter can simplify construction work and reduce construction costs.

Furthermore, by using the hallway pillars as the vertical gutter, there is no need to provide a gutter or a vertical gutter. Therefore, the beauty of the building is not impaired and a sense of luxury is created.
