JPH073125B2 - Basement for existing house - Google Patents

Description

The present invention relates to a basement for a house.

[Conventional technology]

In recent years, underground prices have been reconsidered due to skyrocketing land prices in cities, and there are increasing demands for basements.

In order to provide a basement in a general house, most of the time, when building a building, the basement is designed and constructed as a part of the building in advance.

[Problems to be Solved by the Invention]

In this way, it is good to build a building with a basement from the beginning, but to attach a basement to an existing building later, you will have to dig up under the floor unless you have a sufficient site in the garden. Things, such as capsule-type rooms, are limited to:

However, the demand for basements, including storage units and food storage, will require a certain level of size and robustness to be used as a disaster evacuation shelter, and it is impossible to attach them to existing buildings. It was

The object of the present invention is to eliminate the disadvantages of the conventional example described above, and as a basement that can be attached later to an already constructed building, the basement for an existing house that is as large and rigid as possible and can be constructed at low cost. To provide.

[Means for Solving the Problems]

In order to achieve the above object, the present invention forms a tunnel by a shield construction method in a city basement underground where houses are lined up, partitions the inside of the tunnel with partition walls to define a basement space, and provides a shaft for each basement space. The gist is to connect with each house, and to provide a floor in the tunnel and use the continuous underfloor space as a common groove for piping and wiring.

[Action]

According to the present invention as set forth in claim 1, since the tunnel is formed by the shield method, the tunnel can be constructed by partition walls even under the ground where the houses are already lined up without affecting the above-ground houses. Since the basement is obtained, it becomes a so-called row house collective basement, which is a robust and large space.

These basements are connected to the houses on the ground through the shafts so that they can enter and exit.

According to the present invention as set forth in claim 2, in addition to the above-mentioned action, a basement and a common ditch are made to coexist, but this common ditch is used not only as the basement itself, but also as a facility on the ground. It can be used as a cable, and can meet the demand for undergrounding of electric lines, telephone lines, TV lines, etc. that eliminates electric poles on the ground.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partially cutaway perspective view showing an embodiment of an existing residential basement of the present invention, and FIGS. 2 and 3 are longitudinal side views of essential parts, in which 1a, 1b, 1c, 1d are shown. ,… Are homes, which are so-called city-land.

These houses 1a and the like may be existing ones, but the tunnels 2 are formed in the basement lined by the shield construction method.

The shield construction method for constructing the tunnel 2 may be a commonly used one, in which the starting hole and the reaching hole are formed in a vacant land without housing, and the segment ring 3 is assembled while excavating with the shield machine set in the starting hole. The tunnel 2 is formed.

The starting hole and the reaching hole are left as they are and used as the shaft 4 for the common groove.

A deck 5 serving as a floor plate is installed in the tunnel 2 in the longitudinal direction, and a space under the deck 5 is secured as a joint groove 6 as a continuous underfloor space in the tunnel 2.

Further, in the tunnel 2, the upper part of the deck 5 is partitioned by a partition wall 7 in the length direction of the tunnel to divide it into a basement space 8, and a shaft 9 is provided in each basement space 8 to connect with the above-ground house. Let

After the tunnel 2 is formed, the vertical shaft 9 may be dug vertically from the ground, and the segment ring 3 at the position where it abuts the tunnel 2 may be omitted and integrated.

Further, as shown in FIG. 2, the upper end of the vertical shaft 9 can be exposed to an entrance / exit 11 provided on the indoor floor 10 of the house, or can be opened to an entrance / exit building 12 provided in the garden. Further, an elevating ladder 13 is provided in the vertical shaft 9.

On the other hand, in the common groove 6 as the underfloor space, cold water, hot water,
Pipes / wirings 14 such as hot air, cold air wires, CAT cables, and telephone lines are laid, and these pipes / wirings 14 are shared trench shafts 4
Via a central plant (not shown).

The piping / wiring 14 can be used not only for the equipment of each basement space 8 but also can be used for the equipment of each house by being drawn into each house through the basement space 8 and the shaft 9 by the rising pipe 15. .

In some cases, a ventilation device 16 may be installed under the indoor floor 10 of each house to allow ventilation of each basement space 8. The layout of each basement space 8 is such that flooring material is applied on the deck 5 or a shelf is used. It is possible to freely consider how to install the furniture and bring in furniture and fittings to enhance habitability.

In this way, each basement space 8 can be moved in and out of the shaft 9 as an attachment to the house located above it, and the basement space 8 is a robust one whose outer contour is continuous with the tunnel 2 by the segment ring 3. Also, it is not affected by the earthquake in the basement, so it is also suitable as an emergency shelter.

In addition, since a basement space 8 formed by such a tunnel 2 is located in front of a house to be newly constructed, a vertical shaft 9 can be provided to connect the vertical shaft 9 to the ground before building the house. You may keep it.

〔The invention's effect〕

As described above, since the existing residential basement of the present invention uses the tunnel constructed by the shield construction method, it can be constructed at a low cost without affecting the above-ground houses even under the ground where the houses are already lined up. Since it is constructed as a tenement-like basement, a solid and large space can be obtained.
