Abstract

PROBLEM TO BE SOLVED: To take in ventilation and natural lighting by covering the upper section of a top-face opened-shaped basement with a skip floor made higher than the floor face of a ground floor while forming a clearance between the skip floor and the floor face. SOLUTION: A box-shaped basement unit, in which a top face is opened, is formed of steel sheets supported by frames made of steel, waterproof sheets and heat-insulating materials on the outside. The basement unit is installed into a ditch formed by excavating the ground. The upper section of the basement unit is covered with a skip floor 2 made higher than the floor face 3 of a peripheral ground and a clearance 4 is formed between the floor face 3 and the skip floor 2, thus constructing a basement 1. Accordingly, since ventiation can be taken in from the clearance 4 and natural lighting cast in from the window, etc., of a building body can be taken in, a dry area, etc., for taking in natural lighting and ventilation need not be mounted, and execution cost can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basement that can be used as a relatively large storage room or a living room such as a study.

[0002]

2. Description of the Related Art Recently, in houses built in cities, the demand for basements has been increasing in order to make effective use of the volume. 2. Description of the Related Art Conventionally, this kind of basement has various structures, such as one constructed entirely on site, a panel type, and a unit type. In addition, a dry area is provided outside to incorporate lighting and ventilation.

[0003]

In the above-mentioned conventional basement, a large amount of ground must be excavated in order to be able to be used as a large storage or living room, and the amount of residual soil treatment increases, and However, there is a disadvantage that the construction period is long and the construction cost is high. In particular, panel-type or unit-type panels have larger panels and units, and unit-type panels require transportation by large vehicles such as special trailers, which increases transportation costs and limits the transport area. There are inconveniences. Furthermore, providing a dry area for daylighting further increases construction costs.

An object of the present invention is to provide an inexpensive basement capable of solving the conventional drawbacks and incorporating ventilation and lighting and capable of being transported by a small vehicle even in a unit type. It was done as.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to increase the height of a floor space above an open-topped basement space formed by excavating the ground under the floor, above the floor surface of the ground floor. And a gap is provided between the skip floor and the floor surface so that ventilation or lighting or ventilation and lighting is introduced into the basement space.

In the invention of claim 2 of the present application, the basement space is formed of a box-shaped unit having an open upper surface.

[0007]

FIG. 1 is a schematic sectional view of a building having a basement according to the present invention. The building in this figure is a three-storey house, in which the upper part of the open-topped basement (1) provided by excavating the ground is higher than the surrounding ground floor (3). Covered with floor (2). And a gap (4) is provided between the floor (3) and the skip floor (2),
Ventilation is taken in from the gap (4), or daylight that enters through windows or the like of the building body is taken in.

FIG. 2 shows a more detailed structure of the basement (1). (5) is a box-shaped basement unit having an open upper surface, which is manufactured in advance in a factory and excavated the ground (6).
It is set up inside. This basement unit (5)
For example, it is composed of a steel plate supported by a steel frame, a waterproof sheet, and an outer heat insulating material, but the detailed structure is omitted.

A mortar (7) is installed on the lower surface side of the basement unit (5), and a concrete portion (10) is filled on a side surface portion through a backfill soil (9). (11) is the foundation pile, (12) is the foundation concrete cast on the upper side of this foundation pile (11), (13) is supported by the foundation pile (11) through the foundation concrete (12) This shows the steel base beams to be built, and the skeleton of the building is built above it. (1
4) is the concrete under the floor, which is cast together with the foundation concrete (12) and the concrete (10) around the basement.

[0010] Steel joists (15) on the slab concrete (14)
A floor member (19) made of a concrete plate is provided on the steel joist (15), and a floor plate (20) is provided on the upper surface side.

A wooden joist (24) for supporting the skip floor (2) is installed so as to straddle above the basement (1) and has a skip floor on the joist (4). (2)
Is installed. The step floor (2) may be a board-style Western style as shown in the figure or a tatami floor.
(25) is a stair for ascending and descending between the basement (1) and the floor (3) on the ground floor. An interior board (26) is attached inside the basement unit (5).

In the above, the basement unit (5) has a total height of about 1800 mm or less, and is manufactured in a size that can be sufficiently transported by a small transport vehicle of about 2 tons. By changing the height of the floor (2), the basement (1) can be used as storage or as a living room in a study or the like. For example, in the case of storage, the height of the skip floor (2) does not need to be too high, and when lighting or ventilation is not required, it is completely sealed without providing the gap (4). You may. Alternatively, when the skip floor (2) is used in a living room or the like, the skip floor (2) can be installed in a state of being raised higher, and the gap (4) can be enlarged. Further, when the floor is used as a floor which is lower than the floor surface (3) of the ground floor (3), the upper part of the basement (1) can be left uncovered by the skip floor (2) as described above. It is.

FIG. 3 shows an example of the use of the basement (1) as described above. FIG. Skip floor on side (2)
In the figure, (B) shows the basement (1) completely closed and used only for storage, and (C) shows the basement unit (5) with a shallower floor and a skip floor. (2)
, The basement (1) is a kind of skip floor.

[0014]

As described above, according to the present invention, since the upper part of the basement is covered with the skip floor independent of the surrounding floor of the ground floor, the height of the skip floor serving as the ceiling of the basement is covered. By changing the length, there is an effect that various usage forms are possible. By providing a gap between the skip floor and the surrounding floor surface, it is possible to take in lighting and ventilation, and a basement structure with an open feeling can be obtained.

[0015] Further, even when used as a living room or a large storage, the height of the skip floor can be sufficiently increased, whereby the amount of excavation of the ground can be reduced and the basement is transported as a unit. However, the height of the unit can be made relatively low, and there is an effect that the whole unit can be sufficiently transported by a compact and small transport vehicle. In addition, as described above, it is not always necessary to provide a special dry area for taking in light and ventilation, and the effect that the construction cost can be significantly reduced is obtained.
