Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-story building unit structure, and more particularly to an improvement of a structure in which building units are stacked to construct a multi-story building and an entrance is provided on two or more floors. is there.

[0002]

2. Description of the Related Art In a multi-storey building with two or more floors,
In the case where two or more households live in the building, the entrance may be built on any floor above the second floor.
This also applies to the unit construction method for constructing a multi-storey building by stacking building units.

FIGS. 3 (A) and 3 (B) show an example of the construction in the case where the entrance is constructed on the second floor in the unit construction method.

As shown in the figure, an entrance 12 is provided on the second floor of the multi-storey building unit 10. Conventionally, the entrance door 14 of the entrance 12 is installed by providing an opening in the outer wall portion of the building unit. Therefore,
The part of the tap 18 inside the entrance is the outer wall 16 of the building unit
It is configured inside the area surrounded by the
The stairs 20 for climbing up to 2 are installed outside the outer wall 16. That is, it is configured as an outer staircase.

Incidentally, Japanese Patent Application Laid-Open No. 52-104317 discloses an example of a staircase unit in which an entrance room is provided inside the unit in the unit construction method. In this example, the entrance room is configured inside the building unit installed on the first floor, and the stairs to go upstairs from the entrance room are also built in the unit. I am trying.

[0006]

However, in the above-mentioned conventional unit construction method in which a staircase is constructed on two or more floors, as shown in the schematic configuration diagram of FIG. It is installed by cutting out a part of the floor beam 22 that constructs the outer peripheral portion of the floor portion of 10a. That is, when constructing the entrance without cutting out the floor beam 22, the floor beam 22 is formed at the entrance / exit of the entrance.
It is necessary to get over the road and it is cut off because it interferes with walking.

Therefore, since the portion of the entrance door 14 is cut out, it is difficult to maintain the ramen structure as a whole. Therefore, conventionally, it is necessary to reinforce the strength by providing the reinforcing pillars 24 on the downstairs building unit 10b side and further providing the reinforcing pillars 26 on the upstairs building unit 10a side as shown in the figure. .. Further, this reinforcing work causes a high cost and further restricts the plan variation in the unit construction method.

Further, as described above, the building unit 1 on the upper floor
When the entrance is constructed without notching the floor beam 22 of 0a,
That is, when the entrance door 14 is installed above the floor beam 22, there arises a problem that a sufficient depth cannot be ensured at a part of the entrance tap 18 that is inside the entrance door 14.

5 (A) and 5 (B) are shown in FIG. 3 (A).
AA sectional view and BB sectional view of FIG.

As shown in the figure, the entrance door 14 is attached to the upper side of the floor beam 22 (B in the same figure), and the part of the tap 18 on the inside is relatively shallow with respect to the floor surface of the floor 30 in the room. is set up. That is, since the upper surface of the bottom of the beating part 18 cannot be greatly lowered to the lower position of the entrance door 14, it has such a shallow structure. That is, when the user enters the entrance with the entrance door 14 open, there is a problem that it is difficult to walk when the part of the tap 18 is considerably lower than the height of the floor surface of the door part. However, like this
The shallow depth of the part had a problem that the design of the entrance did not look good.

The tap 18 has a waterproof pan 18a on its upper surface, and a base plate 18b is installed below the waterproof pan 18a. Then, the tap 18 is installed at the upper position of the floor girders 32 hung between the outer floor girders 22 and the under-entrance girders 34 hung so as to be orthogonal to the floor girders 32.

Further, the staircase unit disclosed in the above-mentioned Japanese Patent Laid-Open No. 52-104317 does not have a structure in which the entrance is constructed on the second or higher floor, and the unit on the first floor is used. The entrance room is constructed, and a staircase and an entrance to the next room are formed inside the unit. Therefore,
Although we have improved the accessibility to each adjacent room centering on the entrance hall, the above problems in installing the entrance to the second floor and above have been solved without any problem. there were.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to separately provide a reinforcing member when building a doorway in a building unit on any one of two or more floors and to use a door with a tap It is to provide a multi-story building unit structure that can take sufficient depth.

[0014]

In order to achieve the above object, a multi-story building unit structure according to a first aspect of the present invention is a multi-story building unit structure in which a entrance is provided on any one of two or more floors of a multi-story building in which building units are stacked. In a multi-story building unit structure that is to be provided, in the entrance door provided in the area surrounded by the floor beams that form the outer periphery of the building unit floor on the upper floor, and the floor space outside the door and the entrance door. An entrance part consisting of a certain entrance front part and a part adjacent to the entrance front part of the above-floor building unit floor part are removed by a predetermined range, and a ceiling structure part corresponding to the above-mentioned removal range of the downstairs building unit is provided. A removed and formed stairwell, and a stairway portion that is installed in the part of the stairwell and hung between the downstairs building unit floor to the front of the entrance of the building unit floor above. It is equipped with To.

On the other hand, the multi-story building unit structure according to claim 2 is the multi-story building unit structure according to claim 1, wherein the lower end surface of the entrance tap is in the vertical direction in the installed state of the building unit on the floor. It is characterized in that the position is set to be substantially equal to the bottom end face of the floor of the upper building unit.

Further, the building unit on the upper floor where the entrance is constructed is one of two or more floors, but when a general residence is assumed, it is usually the building unit on the second floor. Is.

Further, the doors, the taps, and the stairs constituting the entrance are not particularly limited in their configurations, and conventional configurations can be used.

[0018]

According to the multi-story building unit structure according to claim 1 having the above-mentioned structure, the entrance portion constituted by the entrance door, the tap and the front portion of the entrance constitutes the outer peripheral portion of the floor portion of the building unit above the floor. Since it is installed in the area surrounded by the floor beams,
The operation of opening the entrance door and entering the room from the entrance is performed in the building unit on the floor. Therefore, the staircase is also formed so as to extend inside the building unit, that is, from the floor of the downstairs building unit to the front entrance of the floor of the upstairs building unit.

Therefore, unlike the conventional case, there is no need to go up the stairs outside the unit, open the entrance door from the outside of the unit, pass through the floor beams, and enter the entrance.
As a result, since the floor beam does not pass through during the operation of entering the entrance, it is not necessary to make a notch in the floor beam, and therefore, it is not necessary to add a reinforcing member such as a pillar to cope with the notch. ..

Further, the lower end side of the entrance door can be installed at a lower position than the upper position of the floor beam as long as it is within the range of the building unit on the floor, so the bottom position of the knocking part of the entrance is also It can be made lower than the upper part of the floor beam, so that the difference in height between the beating and the upper surface of the floor inside can be made large. Therefore, the depth of the tapping portion can be made sufficient, and the design of the entrance can be improved.

On the other hand, in the multi-story building unit structure according to claim 2, the lower end surface of the entrance portion is set to be substantially equal to the lowermost end surface of the floor portion of the installed building unit. The tapping part is configured to be the deepest possible structure, and it is possible to make the appearance very good even when building the entrance in the building unit installed on the second floor or higher. Become.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIGS. 1 (A) and 1 (B) are explanatory views showing the characteristic portion of the multi-story building unit structure according to the embodiment. The section 12 and the staircase section 36 are arranged. That is, unlike the conventional example shown in FIG.
In addition to 8, the entrance door 14 and the entrance front portion 38 are all installed in the floor beam 22 of the building unit. Similarly, the staircase 36 is also installed inside the unit so as to extend from the front entrance 38 to the floor below.

Therefore, as shown in FIG. 3B, the area of the portion where the staircase portion 36 and the front entrance portion 38 are joined together does not hinder the user from going up and down the staircase, as shown in FIG. The floor portion 40 of 10a is removed to form a blow-through portion 42. This allows the stairs 36 to go up and down.

FIG. 2 is a diagram showing a specific structure of the entrance portion 12 of the embodiment. FIG. 2A is a line A--A in FIG.
The sectional view and the same figure (B) respectively show the BB sectional view.

As shown in FIG. 3B, the entrance door 14 is installed so that its lower end is located at a position lower than the upper end surface of the floor beam 22. Therefore, the part of the beating 18 can also be installed at a low position, and as shown in the drawing, the beating 18
The bottom surface of the base plate 18b, which is the bottom surface of the floor beam 22, is set at a substantially vertical position that is substantially the same as the bottom surface of the floor beam 22. That is,
It is set so as to constitute a part of the bottom of the upper floor building unit 10a. Therefore, the difference in height between the upper surface of the floor portion 30 on the indoor side and the upper surface of the tap 18, that is, the depth W of the tap 18 is much larger than that in the conventional example. As a result, the tappet 18 having a sufficient depth can be formed as in a normal entrance, so that the design of the entrance provided in the building unit is improved.

Further, as shown in the drawing, since it is not necessary to cut out the floor beam 22 in the portion of the entrance door 14, there is no risk of disturbing the rigid frame structure of the entire building unit, and there is no need to separately provide a reinforcing member. ..

The floor beam 22, the tap 18 and the floor beam 3
The upper end surface of the downstairs building unit 10b abuts on the lower side of 2.

The present invention is not limited to the above embodiments, but various modifications can be made within the scope of the invention. For example, the position of the entrance 12 in the building unit is not limited to one corner as in the above-described embodiment, but may be set in various places such as the substantially central part of the building unit depending on the positional relationship with the stairs 36. It is possible to set. Further, the entrance door 14 is not limited to the rotary door type, but may be a sliding door type.

[0030]

As described above, according to the inventions according to claims 1 and 2, a reinforcing member such as a pillar is separately provided when the entrance is constructed on two or more floors of a multi-story building in the unit construction method. It does not need to be added and can maintain sufficient strength,
Further, since the designability can be improved by sufficiently securing the depth of the entrance, particularly the tapping, it is possible to expand the plan variation in the unit construction method.
