Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airtight structure for a domestic elevator mainly installed in a house.

[0002]

2. Description of the Related Art In recent years, homes equipped with domestic elevators have become widespread. When installing a household elevator, it is necessary to install an elevator shaft that penetrates from the lower floor to the upper floor inside the building, but unless the airtightness of this elevator shaft is secured sufficiently, the airtightness of the entire building This will hinder the securing of

[0003]

The conventional domestic elevators do not have a structure in which airtightness is sufficiently taken into consideration, which causes the airtightness of the entire building to be impaired. It was often an obstacle to clearing strict standards such as Generational Energy Conservation III regional standards.

Therefore, an object of the present invention is to provide an airtight structure for an elevator which can solve the above problems and ensure a high airtightness.

[0005]

In order to solve the above problems, in the present invention, a gypsum board is attached to the ceiling portion and the inner wall portion of an elevator shaft, and a rising portion of a foundation surrounding the elevator shaft and a base are formed. It is characterized in that a gap is filled with a sealing material.

A gypsum board attached to the inner wall is
The foundation is raised from the upper surface. Further, a heat insulating material is attached to the side surface inside the elevator shaft at the rising portion of the foundation.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an elevator shaft of a domestic elevator according to an embodiment of the present invention. The elevator shaft (1) penetrates from the first floor to the third floor of the building and is formed in, for example, a substantially rectangular tube shape.

On the ceiling portion (2) of the elevator shaft (1), as shown in FIGS. 1 and 2, for example, steel field edges (3) (3) ... Reinforced gypsum boards (4) (4) ... Are attached in a substantially horizontal direction across the lower surfaces.

The inner wall portion of the elevator shaft (1)

... and beams (8) (8) ... Assembled wall frame (9)
Further, the reinforced gypsum board (4) (4) is attached in a substantially vertical direction. These reinforced gypsum boards (4) (4) ... are foundation rising parts (10) (10) ... around the elevator shaft (1).
Stand up from the upper surface of the reinforced gypsum board on the ceiling (2)
(4) (4) ... has reached.

In the inner wall portion (5) on the partition side, as shown in FIGS. 1 and 3, the beams (8) (8) ... Studs (11) (11) ...
The reinforced gypsum board (4) (4) ... is attached to the.

Further, the foundation rising portions (10) (10) surrounding the elevator shaft (1) and a spacer (12) on the upper surface thereof.
As shown in FIGS. 4 and 5, a sealing material (17) such as urethane foam is filled in the gap between the bases (15), (15) ... The gap is closed. The filling of the sealing material (17) is performed before the gypsum board (4) (4) is attached to the inner wall portions (5) (5), and is protruded more laterally than the bases (15) (15). The sealing material (17) is cut so as not to hinder the attachment of the gypsum board (4) (4).

Further, heat insulating materials (20) (20) ... Are attached to the side surfaces of the foundation rising portions (10) (10) ... Inside the elevator shaft (1).

In the figure, (21), (21), ... Are entrances (6)
(6) It is an open / close door arranged at. Further, (22) is a lifting hook for hooking a wire for suspending and installing the elevator cage. Lifting hook (22) is on the ceiling (2)
Gypsum board (4) fixed to the nearby beam (8) and on the ceiling (2)
Since it penetrates through and faces the inside of the elevator shaft (1), the penetrating portion is closed with a sealing material.

As described above, the reinforced gypsum board (4) is attached to the ceiling portion (2) and the inner wall portions (5) (5) of the elevator shaft (1).
By sticking (4) ..., the space inside the elevator shaft (1) is surrounded by the reinforced gypsum board (4) (4) ... except for its entrance / exit (6) (6) .. In the foundation part, the foundation rising part (10) (10) ... and the foundation (15) (1
5) Since the gap between it and ... is closed by the sealing material (17), it is possible to improve the airtightness and heat insulation of the elevator shaft (1), which in turn enhances the airtightness of the entire building. be able to. As a result, it becomes possible to comply with strict standards such as the Next Generation Energy Conservation III regional standard, even though the house is equipped with a household elevator.

The present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention.

[0016]

As is apparent from the above description, according to the present invention, a plaster board is attached to the ceiling portion and the inner wall portion of the elevator shaft, and further, in the foundation portion, the gap between the foundation rising portion and the base is provided. Since the sealant is closed, the airtightness in the elevator shaft can be sufficiently secured, and the heat insulating property can be improved.

A gypsum board attached to the inner wall is
By raising from the upper surface of the foundation rising portion, the gap between the foundation rising portion and the base can be surely closed, and the airtightness inside the elevator shaft can be further enhanced. Furthermore, since the heat insulating material is attached to the side surface of the foundation rising portion, the heat insulating property in the elevator shaft can be further enhanced.
