Abstract

(57) [Summary] [Purpose] Excellent appearance and cost reduction. [Structure] In an office building, a slit-shaped return path opening 18 is provided on a ceiling 6 of a corridor 1 along a boundary 17 between the corridor 1 and an office room 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a return path opening structure in an office building.

[0002]

[Prior art]

 In small and medium-sized office buildings, in addition to the amount of air needed for ventilation and air conditioning in the office room, it is necessary to ventilate air from the office room through the corridor in an amount commensurate with the exhaust air from the bathroom and toilet. Is generally done.

FIG. 2 shows a structure of a return path opening in a conventional office building. FIG. 2 (A) is an overall perspective view and FIG. 2 (B) is a sectional view. In FIG. 2 (A), an office 2 and a restroom 3 are arranged across the corridor 1, and the corridor 1 is provided with an opening / closing door 4 to the office 2 and an entrance / exit 5 to the restroom 3. There is. An illumination lamp 7, an emergency illumination lamp 8 and a fire alarm 9 are attached to a ceiling portion 6 of the corridor 1, and a return path opening portion 10 is formed. A guide light 12 is provided at the entrance 11.

As shown in FIG. 2B, an exhaust port 14 is formed in the ceiling portion 13 of the office room 2, and a ventilation fan 16 is provided in the ceiling portion 15 of the restroom 3. There is. The air in the office room 2 is exhausted from the exhaust port 14 of the office room 2 through the return path opening 10 of the corridor 1, the corridor 1 and the lavatory 3 by the ventilation fan 16 as shown by an arrow in the figure.

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned conventional retampath opening structure, since the illumination lamp 7, the emergency lighting lamp 8, the fire alarm 9, and the retamper opening 10 are arranged side by side on the ceiling 6 of the narrow corridor 1, the appearance is limited. There is a problem that the cost will increase as a result that the building will not look good and that the appearance of the return path opening 10 will be improved due to that.

The present invention solves the above problems, and an object of the present invention is to provide a return path opening structure that is excellent in appearance and can reduce cost.

[0007]

[Means for Solving the Problems]

 For this reason, the retum path opening structure of the present invention is such that, in an office building, a slit-shaped retum path opening 18 is provided on the ceiling 6 of the corridor 1 along the boundary 17 between the corridor 1 and the office 2. Characterize. It should be noted that the numbers added to the above-mentioned configurations are to be compared with the drawings in order to facilitate the understanding of the present invention, and the configurations of the present invention are not limited thereby.

[0008]

[Action]

 In the present invention, the air in the office room 2 is exhausted from the exhaust port of the office room 2 through the slit-shaped return path opening 18 of the corridor 1, the corridor 1, and the lavatory 3 from the ventilation fan 16.

[0009]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1A and 1B show an embodiment of a return path opening structure in an office building according to the present invention. FIG. 1A is an overall perspective view, and FIG. 1B is an enlarged sectional view of a main part of FIG. 1A. is there.

In FIG. 1 (A), an office room 2 and a rest room 3 are arranged across a corridor 1, and an opening / closing door 4 to the office room 2 and a doorway 5 to the rest room 3 are arranged in the corridor 1. It is provided. An illumination lamp 7, an emergency illumination lamp 8 and a fire alarm 9 are attached to the ceiling 6 of the corridor 1, and a guide lamp 12 is provided at the entrance / exit 11. In addition, a slit-shaped return path opening 18 is formed in the ceiling 6 of the corridor 1 along the boundary 17 between the corridor 1 and the office room 2.

In FIG. 1B, the slit-shaped return path opening 18 covers the exhaust hole 18 a formed by punching a large number of holes in a resin, a zinc iron plate or the like, the mounting portion 18 b, and the end of the ceiling portion 6. It is composed of a decorative plate 18c. The exhaust hole 18a is formed at a position retracted from the ceiling 6 and the length of the exhaust hole 18a is about 15 to 20 mm. Therefore, when viewed from the corridor 1, it is hardly noticeable in appearance. In addition, the boundary portion 17 has a neat appearance. Further, the material for the opening of the return path can be made of a material having a low cost. The air in the office room 2 is exhausted from the exhaust port of the office room 2 through the slit-shaped return path opening 18 of the corridor 1, the corridor 1, and the rest room 3 by the ventilation fan 16 (FIG. 2).
