JPH07116813B2 - How to connect vertical gutters in an assembled house - Google Patents

Description

TECHNICAL FIELD The present invention relates to a vertical gutter connection method for an assembled house.

(Prior Art) A prefabricated house is, for example, as described in Japanese Patent Publication No. 62-62224, a box type of a certain size that can be carried,
In addition, the interior and exterior finished housing units are produced in advance, a plurality of them are transported to the construction site, and assembled at the site to form a single house.

This prefabricated house has been adopted more and more widely in recent years because it has a characteristic of being a standardized house with a short construction period and good dimensional accuracy.

Conventionally, in the construction of this prefabricated house, a housing unit was installed in contact with a prefabricated foundation, and then the roofing material was roofed at the prefabricated construction site.

However, it has been desired to roof the roofing material in advance in the factory, because improving the assembly completion level of the assembled house will bring out the characteristics of the assembled house.

However, if you assemble a housing unit that is covered with roofing material in advance, the roof will be at the same height, and the flow of rainwater will deteriorate,
It will be difficult to get rid of rain.

As a method for solving such a problem, the inventor installed the respective housing units so as to be separated from each other by the vertical gutters, provided the vertical gutters between the housing units, and provided rainwater on the roofs of the respective residential units. Was invented for each housing unit by a vertical gutter provided between the housing units, and was previously filed as Japanese Patent Application No. 1-312435 (see Japanese Patent Application Laid-Open No. 3-172427).

(Problems to be solved by the invention) However, when a downspout is installed between the housing unit and the housing unit, it is necessary to connect the downspout midway from the roof of the house to the ground because it is long.

However, since the space between the housing units is small, it is a difficult work to connect the downspout in this narrow space. Then, the objective of this invention is providing the connection method of the down gutter which can perform such difficult work easily.

(Means for Solving the Problems) The present invention has been made to solve the above problems and achieve the above objects, and a plurality of housing units are installed at least as far as a downspout is provided. A downspout connection method for installing a downspout between a housing unit and a housing unit, in which a downspout having a female screw in which a guide portion is provided at the tip of the female screw is turned upside down. It is installed between a housing unit and a housing unit, and a vertical gutter having a male screw is inserted into the guide part of the vertical gutter having the female screw from above, and is screwed in to be connected.

(Operation) In the present invention, a vertical gutter having a guide portion at the tip of the female screw is first provided between the housing units with the guide portion facing upward.
From above, the downspout having a male screw is inserted into the guide portion of the downspout having the female screw.

Normally, in order to screw a downspout having a male screw into a downspout having a female screw, it cannot be screwed in unless the screw threads are aligned. Conventionally, this screw thread is fitted in a narrow place. However, in the present invention, this insertion is extremely easy because the male screw is not directly inserted into the female screw but the male screw is inserted into the guide portion having no screw.

Next, the downspout having the male screw is rotated and screwed into the downspout having the female screw.

At this time, if the downspout having the male screw and the downspout having the female screw are not in a straight line, the threads are not aligned and screwing is difficult, but in the present invention, the guide of the downspout having the female screw is provided. When a vertical gutter having a male screw is inserted into the part, the two are naturally aligned with each other as they are inserted, which facilitates the screwing.

(Example) An example of the present invention will be described with reference to the drawings.

The drawings show one embodiment of the invention,
The drawing is an explanatory view showing a state in which a downspout is connected, FIG. 2 is a front view showing a downspout used in the present invention, and FIG. 3 is a front view showing a female screw portion of the downspout shown in FIG. Fig. 4, Fig. 4 is a front view showing the male screw portion of the downspout shown in Fig. 2, Fig. 5 is a perspective view showing the skeleton of the housing unit, and Fig. 6 is a state in which the housing unit is installed. It is a perspective view.

In the figure, reference numeral 1 denotes a housing unit, and as shown in FIG. 6, a plurality of housing units 1 are installed and assembled to form an assembled housing.

The skeleton of this housing unit 1 is, as shown in FIG.
It consists of pillars 11, ceiling beams 12, and floor beams 13, and beam beams 14 are bridged to the floor beams 13, and joists 15 are passed on the beam beams 14. A ceiling joist 16 is bridged to the ceiling beam 12.

As shown in FIG. 6, a plurality of housing units 1 are assembled to form a house. At this time, the housing units 1 are installed with a vertical gutter between them. .

2 is a vertical gutter with a total length of 2925 mm and an outer diameter of 50 mm, which is installed between the pillars 11 of the housing unit 1.

As shown in FIGS. 2 and 3, a female screw 21 is provided at one end of the downspout 2. A guide portion 22 having an inner diameter of 53 mm is provided at the tip of the female screw 21.

A male screw 23 is provided at the other end of the vertical gutter 2. A guide portion 24 having an outer diameter of 500 mm is provided at the tip of the male screw 23.

Thus, if not only the guide portion 22 is provided at the tip of the female screw 21 but also the guide portion 24 is provided at the tip of the male screw, the vertical gutter 2 having the female screw 21 is provided in the vertical gutter 2 having the male screw 23. Insertion of 2 is further facilitated.

Next, the construction method and operation of this vertical gutter will be described.

First, a housing unit 1 as shown in FIG. 6 is manufactured in a factory, and is transported to a construction site by a truck.
Put it on the foundation and assemble. At that time, the respective housing units 1 are installed so as to be separated by the vertical gutters 2.

A rainwater drainage pipe is installed passing under the floor from a rainwater drop provided outside, and is set up as a downspout from between columns 11.

As shown in FIG. 1, the vertical gutter 2 is attached such that a female screw 21 provided at the tip of the vertical gutter 2 faces upward.

Next, the guide portion provided at the tip of the female screw 21 of this downspout
The guide portion 24 of the next vertical gutter 2 is inserted into the upper portion 22 from above.

This insertion is easy because the inner diameter of the guide portion 22 is wider than the outer diameter of the guide portion 24 and the guide portions 22 and 24 are not provided with screws.
