Description

  The present invention relates to an entrance part structure of an apartment house, and to an entrance part structure of an apartment house in which an outer corridor is constructed on one side of a group of houses partitioned by a boundary wall.

One of the effective thermal insulation structures in concrete buildings is the so-called external thermal insulation structure, in which a thermal insulation material is attached to the outdoor side of the concrete wall, and an air layer and exterior finishing material for wall finishing are provided on the outside. It has been.
And in this outer heat insulation structure, if it is a part facing the outside air as well as a wall, a heat insulating material will be stuck also on a pillar and a beam, and it will be covered with an exterior material.

However, in a general ridged apartment building as shown in FIG. 5, the pillars a and beams b often protrude from the outer surface of the outer wall c. In particular, on the shared corridor d side, a meter box e for installing a common trunk line and a common vertical pipe for electricity, gas, water, etc., their meters, a gas water heater, an outdoor unit for air conditioning, etc. protrudes from the outer wall c. Therefore, a complicated outer wall surface including those sleeve walls f is formed. Of course, it is possible to provide the meter box e so as to be recessed inside the outer wall c, that is, inside the room, but the floor plan is limited accordingly.
Therefore, generally, as shown in FIG. 5, the meter box e is provided in a state of protruding from the outer wall c, resulting in a complicated outer wall surface.

And the more complicated the shape of the outer wall surface, the more complicated the work of attaching the heat insulating material and the processing and mounting of the exterior material. In the above conventional example, the cost of the outer heat insulating method for the outer wall on the shared corridor d side is high. There was a problem of sticking.
Further, in the above conventional example, since the sleeve wall f of the meter box e becomes a heat bridge, there has been a problem of how to insulate the sleeve wall portion.
In the figure, g is a dwelling unit partitioned by a border wall h constructed in the plane between the beams, and i is a balcony.

Therefore, in Japanese Patent Application Laid-Open No. 2003-105885, although a meter box is provided in a state of protruding from the outer wall on the shared corridor side, it can be easily and inexpensively constructed using a flat panel as a heat insulating material or an exterior material. The following heat insulation structure for a one-way corridor-type apartment house, where there is no risk of the sleeve wall becoming a heat bridge, was provided.
The exterior heat insulation structure of the one-way hall type apartment house disclosed in the above publication is a one-way hall type apartment house in which a shared hallway is constructed on one side of a group of dwelling units partitioned by a door wall and a balcony is constructed on the other side. The outer surface of the column beam on the common corridor side and the outer surface of the outer wall on the common corridor side are flush with each other, a heat insulating material is pasted on the entire outer surface, an air layer and an exterior material are provided on the outside, and the exterior material The meter box is configured by installing a sleeve wall and a cover panel for the meter box on the outside.

In the external heat insulation structure of the one-way corridor type apartment house described in this publication, the outer surface of the column beam on the common corridor side and the outer surface of the outer wall on the common corridor side are flush with each other. The installation work of the material is easy, and the outer insulation structure can be realized easily and inexpensively by using the flat panel as the insulation material and the exterior material, and the sleeve wall for the meter box and the cover panel are installed outside the exterior material. Since the meter box is constructed, the space between the sleeve wall and the outer wall is insulated by the outer heat insulation structure on the outside, and there is no possibility that the sleeve wall becomes a heat bridge. There is a point.
(A) A heat insulating material is sandwiched between the wall of the meter box and the main body wall, but the storage of the part becomes complicated and the end part is poorly stored.
(B) Forming a gap between the wall of the meter box and the main body wall increases the processing cost of the mold and increases the cost.
(C) Since the meter box is attached to the outside of the exterior material, it is necessary to suppress the distance between the exterior material and the wall as much as possible, and the thickness of the heat insulating material is reduced. In the case of the structure of the above publication, the thickness of the heat insulating material seems to be about 30 mm. If you want to make the insulation thicker, you need to increase the width of the outer corridor. In general, when designing a housing complex, it is often designed with a size limit. Moreover, in the Building Standard Law, the width of the corridor needs to be 1200 mm effective between the wall and the handrail, so the construction range is expanded, leading to an increase in cost.
JP 2003-105885 A

  An object of the present invention is to provide an entrance structure of an apartment house that does not have the above-mentioned problems as in the conventional structure, based on a completely new concept.

The said subject can be achieved by the entrance part structure of the apartment house of the structure in any one of following (1)-(3).
(1) The entrance structure of an apartment house where an outer corridor is constructed on one side of a group of houses partitioned by a boundary wall, with a meter box extending almost from the ceiling to the floor facing the entrance door of the entrance The entrance structure of an apartment house, which is provided integrally with a handrail in the outer corridor.
(2) The entrance structure of the apartment house of (1) above, wherein the heat insulating structure of the house is an external heat insulating structure.
(3) The entrance part structure of the apartment house of (2) above, wherein the thickness of the heat insulating material layer used in the outer heat insulating structure is 50 mm or more.

By arranging the meter box on the handrail, it is possible to reduce the cost due to increased construction as in the conventional structure. In addition, by installing a meter box on the opposite side of the entrance door, the entrance to the entrance is not seen, and it acts as a blindfold.
Furthermore, by installing the meter box on the front side opposite to the entrance door, it is possible to prevent wind directly hitting the entrance.
Moreover, according to this entrance part structure, since the meter box was not provided on the wall side, a sufficient space for arranging the heat insulating material on the wall side can be secured, and a heat insulating material having a thickness of 50 mm or more can be installed. Specifically, a heat insulating material having a thickness of 100 mm can be installed in the case of an EPS heat insulating material (wet type) and a thickness of 125 mm in the case of a dry ventilation method.

Hereinafter, an entrance structure of an apartment house according to an embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, in the apartment house in which the entrance structure according to the embodiment of the present invention is adopted, each door 10 is partitioned by a door wall 12, and a balcony 16 is provided outside the outer wall 14 on one side. However, an outer corridor 20 that is a shared corridor is provided outside the outer wall 18 on the other side. A handrail wall 22 is provided on the outer edge of the outer corridor 20.
An entrance 30 is formed adjacent to the inside of the outer wall 18 on the other side, and an entrance door 32 is provided on the entrance 30.

  In addition, the handrail wall 22 of the outer corridor 20 is opposite to the entrance door 32 and has a common trunk line and a common vertical pipe such as electricity, gas, and water, their meters, a gas water heater, and an outdoor unit for air conditioning. Etc., a meter box 40 is provided. The meter box 40 extends from the ceiling 50 to the outer corridor 20 and has a width of about 900 to 1200 mm. Thereby, the meter box can exhibit the effect | action of the blindfold of the entrance part, and the effect | action of blowing inflow to the entrance.

  As shown in the plan view of FIG. 3, the meter box 40 is preferably provided in a state where the rear portion protrudes from the outer surface of the handrail wall 22. Thereby, while the degree which a meter box protrudes to the outer corridor 20 can be made small, the part protruded outside the meter box becomes the accent of the external appearance of the whole building. In addition, the rainwater tank 42 is also neatly stored in the meter box 40.

  A door 44 that can open the entire meter box is provided on the front surface of the meter box 40. As a result, by opening the entire meter box door, it is easy to change the piping and wiring as compared to the conventional meter box.
