JPH03194076A - Basement for existing housing - Google Patents

Abstract

PURPOSE:To reduce a cost by building a tunnel under the ground of an urban district, where housings stand in a row, by shield practice, partitioning the interior of the tunnel by partition walls to partition a basement space, and digging a vertical shaft in each basement space which is coupled to each housing. CONSTITUTION:A tunnel 2 is built under the ground of housings 1a-1d in an urban district in a way that cement rings 3 are assembled together as excavation is effected by shield practice. A deck 5 is installed in the direction of length in the tunnel 2, a space under the deck 5 is ensured as an underground multi-purpose duct 6, a portion above the deck 5 is partitioned by partition walls 7 to form basement spaces, and a space 8 is coupled to a housing on a ground through a vertical shaft 9. The tunnel 2 is built by shield practice and construction is executed without exercising an influence on the housing on a ground, and a solid and large space is formed. This constitution reduces a cost.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to residential basements.

[Conventional technology]

In recent years, with the rise in land prices in cities, the use of underground spaces has been reconsidered, and the number of requests for basements has increased.

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

[Problem to be solved by the invention]

It is fine if you are building a building with a basement from the beginning, but if you are adding a basement to an existing building later, unless you have ample garden space, you will have to dig up the area under the floorboards, which requires a certain amount of scale. (e.g. capsule-type small rooms).

However, if the demand for basements is to be used not only as storage rooms and food storage areas, but also as disaster prevention shelters, a certain level of size and sturdiness are required, and it is impossible to attach them to existing buildings. Ta.

The purpose of the present invention is to eliminate the disadvantages of the conventional example and to provide a basement for an existing residential building that is as large and strong as possible and can be constructed at a low cost as a basement that can be attached to an already constructed building later. It is about providing.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention forms a tunnel underground in an urban area where houses are lined up using a shield construction method, partitions the inside of the tunnel with a partition wall to divide it into a basement space, and provides a vertical shaft for each basement space so that each house The main idea is to establish a floor within the tunnel and use the continuous underfloor space as a common ditch for piping and wiring.

[Effect]

According to the present invention as set forth in claim 1, since the tunnel is formed using the shield construction method, it can be constructed underground in an area where there are already many houses without affecting the houses above ground. Since the basement is obtained, it will be a so-called tenement-like collective basement, and it will be sturdy and have a large space.

Each of these basements is connected to each house above ground via a shaft, allowing access.

According to the present invention as set forth in claim 2, in addition to the above-mentioned effects, the basement and the common ditch coexist, and the common ditch is used not only for the equipment of the basement itself, but also for the above-ground facilities. It can be used for residential equipment, and can also meet requests for underground cables, telephone lines, television lines, etc., which eliminates utility poles above ground.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Fig. 1 is a partially cutaway perspective view showing one embodiment of the basement for an existing house according to the present invention, and Figs. 2 and 3 are longitudinal sectional side views of the main parts. ,...is a residence,
It forms a so-called urban area.

These houses 1a, etc. may be existing ones, but tunnels 2 are formed underground using the shield construction method.

The shield construction method for constructing the tunnel 2 may be a conventional method, in which a starting hole and a reaching hole are formed in a vacant lot with no houses, and the segment ring 3 is assembled while excavating with a shield excavator set in the starting hole. Form tunnel 2.

Note that the starting hole and the reaching hole will be left as they are and used as the shaft 4 for the common ditch.

Inside the tunnel 2, a deck 5 serving as a floor plate is installed in the length direction, and the space under the deck 5 is secured as a common groove 6 as a continuous underfloor space within the tunnel 2.

In addition, the upper part of the deck 5 in the tunnel 2 is partitioned in the length direction of the tunnel by a partition wall 7 to form a basement space 8, and each of these basement spaces 8 is provided with a vertical shaft 9 to communicate with the house above ground. 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 location where it abuts the tunnel 2 may be removed and integrated.

Further, as shown in FIG. 2, the upper end of this shaft 9 can be made to face an entrance/exit 11 provided in an indoor floor 10 of a house, or can be made to open into an entrance/exit building 12 provided in a garden. Furthermore, a lifting ladder 13 is provided within the shaft 9.

On the other hand, the common groove 6 as the underfloor space has cold water, hot water,
Piping and wiring 14 for hot air, cold air, electric wires, CATV cables, telephone lines, etc. are laid, and these piping and wiring 14 are connected to a central plant (not shown) via a common ditch shaft 4.

In addition to being used for the equipment in each basement space 8, the piping/wiring 14 can also be led into each house via the basement space 8 and the vertical shaft 9 with a rising pipe 15, and used for equipment in each house. .

In some cases, a ventilation system 16 is installed under the indoor floor 10 of each house to ventilate each basement space 8. You can freely consider ways to improve livability by installing furniture or bringing in furniture and fixtures.

In this way, each basement space 8 can be accessed through the vertical shaft 9 as an accessory to the house located above it, and the basement space 8 is a solid structure whose outer shell is continuous with the tunnel 2 formed by the segment ring 3. Also, since it is underground and is not easily affected by earthquakes, it is ideal as a disaster prevention shelter.

In addition, even in the case of a newly constructed house, since the underground space 8 created by such a tunnel 2 is located first, a vertical shaft 9 can be installed and connected, and the vertical shaft 9 should be exposed above the ground before the house is built. You can leave it there.

〔Effect of the invention〕

As described above, the basement for an existing residential building of the present invention uses a tunnel constructed using the shield construction method, so it can be constructed underground at low cost without affecting the residential buildings above ground, even in areas where there are already many residential buildings. In addition, since it is constructed as a collective basement similar to that of a row house, it is sturdy and has a large space.
