Description

TECHNICAL FIELD The present invention relates to a piping structure for unit houses that allows piping to be installed indoors in stacked unit houses.

As a unit house structure, a unit house constructed using the butterfly construction method is known (see Patent Document 1). This unit house includes a roof frame, a floor frame, and two gable frames, and when these are assembled, one unit house is constructed. This unit house is foldable and can be opened and erected by lifting the roof frame from the folded state.

Then, by bolting each frame together, a unit house with a box-shaped rigid frame structure is formed. Additionally, since each unit house has an independent box-frame structure, when multiple unit houses are stacked one on top of the other, piping must be installed along the outside walls.

On the other hand, Patent Document 2 describes a dwelling unit in which a plurality of reinforced dwelling units are stacked and used. This dwelling unit has a structure in which a ventilation duct 11 and various piping 12 are arranged along the vertical direction inside the reinforced dwelling unit 10A.

That is, these ventilation ducts 11 and various pipes 12, 13 are stored in a storage section S provided adjacent to the wall 10d within the reinforced dwelling unit 10A.

Utility model registration No. 3205191 Patent No. 2618111

Since the unit house described in Patent Document 1 has an independent box-shaped frame structure, electrical wiring, water supply and drainage piping, etc. are housed along the outer wall surface after the unit house is constructed. Therefore, it was necessary to make holes for piping in the outer wall, which required a large special stepladder, a two-tiered ladder, and an aerial work vehicle. Additionally, the installation of wiring and piping on the outer wall has the disadvantage of detracting from the original design of the building.

On the other hand, the dwelling unit described in Patent Document 2 has a configuration in which various pipes are stored in a storage section provided adjacent to a wall within the reinforced dwelling unit. Therefore, there is an inconvenience that piping construction is limited to the location of this storage section.

However, a feature of unit houses is that the configuration can be changed freely, so with such a configuration in which the pipes are stored in storage areas, there are many restrictions when constructing the pipes, and it is not possible to freely change the layout etc. inside the unit house. There is an inconvenience that makes it difficult.

Therefore, the present invention was created in order to solve the above-mentioned problems, and an object of the present invention is to provide a piping structure for a unit house, which allows piping to be easily installed inside the stacked unit houses.

A first means of the present invention to achieve the above object is to stack unit houses P each including a roof frame P1, a floor frame P2, and two end frames P3, and to install piping inside these unit houses P. The structure includes a piping socket 10 penetrating the roof frame P1 and an openable/closable opening 20 formed in the floor frame P2 vertically below the piping socket 10, so that the stacked unit houses P can be A sleeve pipe 30 is provided extending from a piping socket 10 on the lower layer side to an opening 20 on the upper layer side, and piping is carried out through this sleeve pipe 30.

The openings 20 of the second means are located at the four corners of the floor frame P2, which are formed in advance as bolt joint openings for the connecting bolts 40 that connect the unit house P up and down, and at both longitudinal edges of the floor frame P2. The piping socket 10 is installed on the roof frame P1 vertically above the selected opening 20.

The unit house P of the third means has a butterfly structure in which the unit house is erected by lifting the roof frame from a folded state, and the stacked unit houses P are bolted to the floor frame P2 through openings. It has a structure in which the upper and lower parts are joined by the connecting bolt 40 through the opening.

According to the present invention, piping can be installed indoors in stacked unit houses. Moreover, since the piping work is done indoors, the work can be carried out safely and easily without the need for a large special stepladder, two-tiered ladder, or an aerial work vehicle as required in the past.

Furthermore, by providing the sleeve pipe 30 from the piping socket 10 on the lower layer side of the stacked unit houses P to the position beyond the floor frame P2 through the opening 20 on the upper layer side, the gap between the boundary layer that connects the upper and lower unit houses P can be removed. Even when rainwater blows in, it can be reliably prevented from entering the room from the piping socket 10.

Further, since the piping socket 10 and the opening 20 can be arbitrarily selected from among the plurality of openings 20 formed in advance as bolt joint work openings, the piping position can be freely selected. . As a result, optimal piping construction can be performed to match the internal configuration of each unit house.

Embodiments of the present invention will be described below. The present invention is a piping structure in which piping is installed inside the rooms of stacked unit houses P.

The unit house P of the present invention has a butterfly structure. That is, it includes a roof frame P1, a floor frame P2, and two end frames P3 (see FIG. 1(A)). Then, by lifting the roof frame P1 from the folded state (see (c) in the same figure) (see (a) in the same figure), the unit house is erected (see (b) in the same figure). The stacked unit houses P have a simple design in which the upper and lower unit houses P are joined together using connecting bolts 40 (see FIG. 5).

In order to install vertical piping Q inside the stacked unit houses P, the present invention uses piping sockets 10, openings 20, and sleeve pipes 30 (see FIG. 3).

The piping socket 10 is a member that penetrates the roof frame P1 (see FIG. 4). In the illustrated example, a male socket 11 and a female socket 12, which sandwich a steel plate P1a used for the roof frame P1 from above and below, are screwed together using a screw socket that is attached to an insertion hole opened in the roof frame P1. At this time, a caulking material 13 and a packing 14 are interposed between the male socket 11 and the female socket 12 to prevent the piping socket 10 from loosening and to make it waterproof. Furthermore, an inner gutter 50 is provided on the side surface of the lower end of this piping socket 10.

The opening 20 is a part that opens into the floor frame P2 vertically below the piping socket 10. These piping sockets 10 and openings 20 are vertically arranged one above the other in order to accommodate the vertical pipes Q. Further, these piping sockets 10 and openings 20 can be placed at any position inside the unit house P.

The illustrated opening 20 also serves as an opening 20 previously formed as a bolt joining work opening when connecting the connecting bolt 40 on the indoor side when connecting the upper and lower unit houses P (Fig. 5 reference). After the connection work, the opening 20 is covered with a floor cover P2a so as to be openable (see FIG. 6). Furthermore, a plurality of openings 20 are formed in advance at the four corners of the floor frame P2 and along both longitudinal edges of the floor frame P2 (see FIG. 1(A)). As the opening 20 for piping, the opening 20 formed as these bolt joint work openings is appropriately selected, and the socket 10 for piping is installed in accordance with the position of this opening 20.

The sleeve pipe 30 is a pipe member that is inserted into the piping socket 10 and the opening 20, and the vertical pipe Q is inserted into this sleeve pipe 30 (see FIG. 3). In the illustrated example, a sleeve pipe 30 that fits into the inner diameter of the piping socket 10 is used. On the other hand, the opening 20 through which the sleeve pipe 30 has passed is closed during on-site construction to integrate the sleeve pipe 30 with the floor frame P2 (see FIG. 2).

In order to insert the sleeve pipe 30 into the stacked unit houses P, the sleeve pipe 30 is raised from the piping socket 10 on the lower layer side to the opening 20 on the upper layer side (see FIG. 3). The illustrated sleeve pipe 30 is raised to a position exceeding the floor frame P2 on the upper layer side (see FIG. 2). That is, when unit houses P having a butterfly structure are stacked, no particular waterproofing treatment is applied to the boundary portions. Therefore, if the sleeve pipe 30 that is raised from the piping socket 10 on the lower layer side to the opening 20 on the upper layer side is raised to a position beyond the floor frame P2 on the upper layer side, there is no fear of rain blowing in even during a rainstorm. Further, due to the waterproof environment at the boundary, the sleeve pipe 30 can be raised up into the opening 20 on the upper layer side without exceeding the floor frame P2 (not shown).

The vertical piping Q passing through the sleeve pipe 30 allows various wiring and piping works such as electrical wiring and water supply and drainage piping to be carried out. Further, the present invention is not limited to the illustrated example, and the positions of the piping socket 10 and the opening 20, the configuration and shape of the sleeve pipe 30, etc. can be changed as desired. Furthermore, the design may be freely changed without changing the gist of the present invention.
