Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building having a stairwell and a floor expansion method for the building.

[0002]

2. Description of the Related Art Generally, in a house, when the number of members of a family increases, the floor area of the house is increased by performing an extension and renovation within a range permitted by the situation.
Conventionally, in the case of increasing the floor area of a house, for example, an extension part is constructed adjacent to the pre-renovation house and the pre-reconstruction house and the extension part are connected.

[0003] On the other hand, in a house, by providing an atrium space that connects the first floor (lower floor) and the second floor (upper floor), the interior design of the house is improved and the daylighting property is improved to improve habitability. Is being improved. However, the second floor side of the stairwell is basically nothing.
It cannot be decorated on any part other than the wall, nor can it be used as a storage space. Therefore, when the number of members of the family increases as described above, in order to effectively use the second floor side of the void space, which is a dead space in the house, the floor of the second floor is located at the boundary between the first and second floors of the void space. Can be constructed to increase the floor area.

[0004]

By the way, in the above-mentioned extension and renovation, construction is performed not only on the extension portion but also on the original housing portion, which requires a relatively long construction period and a relatively high cost. It was In particular, when the second floor of the house is to be expanded, the first floor may need to be reinforced, and the construction of the original house may be costly.

Further, during the construction of the extension and renovation, a part of the house may become unusable, which may limit the life. Also, in order to provide a floor in the stairwell space, it is necessary to place a skeleton that supports the floor in the stairwell space, which requires a relatively large-scale renovation, and as in the case of the above-mentioned second floor extension. It may be necessary to reinforce the ground floor, resulting in a relatively high cost and a relatively long construction period.

Further, since the construction of providing the second floor in the stairwell as described above is basically the construction inside the building, there is a possibility that a relatively large part of the house cannot be used during the construction period. As compared with the case where an extension part is provided outside the house, life during the construction period is further restricted, and in some cases, there is a possibility that the house cannot be used during the construction period.

The present invention has been made in view of the above circumstances, and a building and an additional building in which a floor can be easily and inexpensively constructed at a boundary portion between an upper floor and a lower floor of a stairwell in a short construction period. It is intended to provide a floor method.

[0008]

As shown in FIGS. 1, 2 and 3, the building according to claim 1 of the present invention connects the upper floor (second floor 20) and the lower floor (first floor 1). Open space 28
Is provided, and at the boundary between the upper floor 20 and the lower floor 1 of the void space 28, a beam 40 having a strength capable of supporting the floor 44 and serving as a decoration of the void space 28 has both ends as a frame (outer wall). 32, and the horizontal arrangement while being supported by the inner wall 29) was the means for solving the above problems.

According to the above construction, the blow-through space 2 is previously formed.
Since the beams 40 capable of supporting the floor 44 are arranged at the boundary between the upper floor 20 and the lower floor 1 of the floor 8, the floor of the upper floor 20 is set in the stairwell 28 to increase the floor area as described above. 44
In the case of providing the floor, it is not necessary to remodel the house portion before the remodeling, and the floor 44 can be easily constructed on the beams 40 of the void space 28. Therefore, the cost and the construction period for increasing the floor area of the house can be significantly reduced.

Further, since it is not necessary to make a large-scale renovation of the housing portion before the renovation, and the construction period is short, the living limitation in the house during the construction period for increasing the floor area is made small. can do. Further, by providing the beams 40 on the upper floor 20 and the lower floor 1 of the void space 28, there is a possibility that a part of the void space 28 is blocked and the open feeling of the void space 28 is slightly reduced. However, conversely, by providing the beams 40 in the blow-through space 28, it is possible to change the blow-through space 28, which is a space without anything, and enhance the design.

0 ... A plurality of floor bodies (floor panels 41 ...) capable of forming a floor 44 are prepared in advance at the boundary portion between the upper floor 20 and the lower floor 1 of the above-mentioned void space 28 by laying them on top. And the solution. According to the above configuration, when the floor area is increased by utilizing the blow-through space 28, a plurality of floor bodies 41 ... Prepared in advance are carried into the blow-through space 28, and the beam 40 ... Or the beam 40 ... The floor members 41 are placed on the support members 42 and 43 so as to be spread over each other, and the floor members 41 are joined to each other, and the floor members 41 and the beams 40 or the floor member 41 and the supporting members 42 and 43.
The floor 44 can be easily constructed by joining and.

Therefore, even if not a skilled worker, the floor 44
As a result, it is possible to construct a floor 44 as a do-it-yourself carpenter to increase the floor space. Further, since the floor 44 is composed of a plurality of floor bodies 41 ...
Since the floors 41 ... Can be made smaller than the floor 44, it is preferable to manufacture the floors 41 ... at the time of building the building and store them in a storage part such as the attic. it can.

The method for increasing floor space according to claim 4 of the present invention is to increase the floor area in the building according to claim 1, 2 or 3, and when increasing the floor area of the building, By constructing a member (floor panel 41 ...) Which can construct a floor 44 on the beams 40, a new floor 44 is constructed at the boundary between the upper floor 20 and the lower floor 1 of the void space 28. Was used as a means for solving the above problems.

According to the above construction, it is not necessary to reconstruct the housing portion before the floor space is increased, and the beam 4 is provided in the void space 28.
The floor area can be easily increased simply by providing the floor 44 on the 0 or the beams 40 and the supporting portions 42 and 43. In particular, if the floor body 41 of claim 3 is prepared in advance, the floor area can be increased more easily as described above. The member is, for example, the floor panel 41. However, it may be a rod material spanning over the beams 40 ... And a plate material attached to the rod material, and the same as the floor panel 41. A plate material having various strengths may be arranged directly on the beams 40 ...
