Abstract

PURPOSE:To improve the leakage of water reasonably into a basement by a method in which an aperture is formed between a concrete underground body having side walls, a bottom wall and a ceiling wall and the internal wall of the concrete underground body, and a water-proofing treatment is applied to the outside of the internal wall, but not to the side walls and the bottom wall. CONSTITUTION:An aperture (a) is formed between an on-site concrete underground body 1 having side walls 1A, a bottom wall 1B and a ceiling wall 1C and an internal wall 2 having side wall portions, floor portion and ceiling portion. A water-proofing treatment is applied to the outside of the internal wall 2, but not to the side walls 1A and the bottom wall 1B of the body 1. A pit 4 for drain pump and a drain trench 5 to introducing leak water to the pit are provided in the bottom wall 1B. An interior 12B is provided to the inner wall of the heat insulator 12A of the internal wall 2, and a water-proof film 12C is provided to the outside of the heat insulator 12A. The durability of the internal wall 2 can thus be raised, and the cost of construction can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Compared to basement structures, the present invention effectively utilizes the heat insulating and sound insulation/sound absorbing properties of soil to maintain a comfortable temperature that is almost constant throughout the year. 0 Conventional basement construction has a concrete basement structure with side walls, bottom wall and ceiling wall. Inside, an interior wall with side walls, a floor, and a ceiling was constructed in close contact with each other, and waterproofing was applied only to the outer surface of the entire basement. In this case, there were the following problems.

That is, rj! (r) The outer body or inner surface of the outer underground structure, or both the inner and outer surfaces of the structure (if waterproofing has been applied, the soil
i [The waterproof layer is sometimes easily damaged when returning or removing interior walls.
As shown in FIG.
Even if waterproofing treatment (5) has been applied in a sand inch state between As water leaks from damaged or cracked parts of the waterproof layer directly seeps into the interior wall, not only does the 1σi heat effect and decorative effect inherent to the interior wall deteriorate, but the interior of the basement is likely to become wet with products. This was a big problem, especially in living rooms.

The purpose of this method is to improve the above-mentioned problems caused by water leakage by making reasonable modifications between the outer underground framework and the interior walls.

The characteristic structure of the basement structure according to the present invention, which was made to achieve such an object, is that an interior structure having side walls, a floor part, and a ceiling part is provided in a concrete underground structure having side walls, a bottom wall, and a ceiling wall. The walls are constructed so that a gap is formed between them, and at least the side walls and bottom wall of the outer underground framework are not waterproofed, and at least the outer surface of the lfJ interior wall is not waterproofed. At a certain point.

The functions and effects of the above characteristic configuration are as follows.

〈Function〉 Since the interior walls are less likely to be damaged than the underground framework, waterproofing should be applied to at least the outer surface of the interior walls, which do not have to worry about cranking, and this should be separated from the underground framework with an appropriate gap. ta shape 1
By providing a barrier, water leakage from the underground structure can not only be drained to a specified location without touching the interior walls, but also improve the waterproofing of the interior walls compared to the case where waterproofing is applied only to the underground structure. Functions can also be reliably demonstrated over a long period of time. Furthermore, since waterproofing is applied to interior walls that can be manufactured in advance in a well-equipped place such as a factory, this waterproofing work can be carried out reliably and easily with less effort.

<Effects> Therefore, not only the durability of the interior walls is improved, but also the construction period is reduced to 1/1]
While reducing f and Q ha and lowering construction costs, we have created a comfortable basement environment that is unaffected by water leakage, making it suitable for use as a living room.

Embodiments of the configuration of the present invention will be described below based on the drawings.

As shown in Figures 1 to 4, the side wall (IA), the bottom wall (

The side walls (IA) and bottom wall (IB) of the concrete cracked underground structure (1) are not waterproofed, and a waterproof layer (3) made of asphalt is formed only on the upper surface of the ceiling wall (IC). The bottom wall (IB) K is formed with a drain 1 (pump pin (4) and a lattice-shaped drain groove (6) for inducing water leakage thereto).

The inner surface of the side wall portion and the inner surface of the ceiling portion facing the elevating/exiting space (A3) are each treated with quill blowing,
Furthermore, the upper surface of the stair wall (IE) is coated with waterproof mortar and covered with floor tiles.
