Description

The present invention relates to a multi-functional structure provided with a sanitary facility and a storage facility and a seismic structure of a building using the same.

Seismic reinforcement is a method of improving the building's seismic performance by improving the strength, rigidity, and stickiness of the exterior and interior walls and pillars. As a method of seismic reinforcement, there are methods of increasing “proof strength” and “deformation performance” based on the result of seismic diagnosis. In order to increase the proof stress, there are methods such as adding aseismic walls such as seismic walls (bearing walls), steel braces or reinforcing steel braces, and cross walls. In order to improve the deformation performance, there is a method of reinforcing the column with carbon fiber, an iron plate or the like. It is important to plan the seismic walls in a well-balanced manner for earthquake resistance. The optimum method is selected by comprehensively judging the cost, construction period, consistency, and workability. In many cases, seismic reinforcement plans are not carried out solely for reinforcement work, and are often carried out simultaneously with other renewals. This is related to seismic retrofitting work (removal of finish, restoration, consideration for building users) and renewing members other than structures such as sash, glass, equipment, and piping. This is because of the great merit of improving the performance and improving the added value of the entire building. However, in the case of renewal construction, due to the effects of the declining birthrate and aging population, the demand for the number of rooms is reduced due to changes in the household form and diversification of lifestyles, and there is a tendency to dismantle the rooms and renovate them into rooms without large partition walls. Is prominent (for example, Patent Document 1). If a large room is taken along with this tendency, the amount of pillars and bearing walls will be reduced and the earthquake resistance will be lowered. Atriums also tend to reduce seismic resistance due to fewer bearing walls. When a large room is provided on the south side such as a living room, the south side has fewer bearing walls than the north side where sanitation facilities are concentrated, and the arrangement of the bearing walls is biased to the north, making it more fragile when subjected to seismic forces. For this reason, it is difficult to reinforce the work by removing the pillars and partition walls due to the renovation work, which requires a work period and cost, and is currently limited to partial refurbishment.

Japanese Patent No. 4691194

Making earthquake-resistant old buildings that are feared to become defective stocks and regenerating them as good stocks that can be used in the future is not only from the economic aspect of effective use of assets, but also from damage such as collapse of buildings due to earthquakes. It is important and meaningful to protect people's life, body and property. When a large room is set up on the south side such as a living room to cope with changes in external factors such as changes in household form and lifestyle diversification in order to regenerate into a good stock that can be used, The bearing walls are less than the north side where sanitary facilities are concentrated, and the arrangement of the bearing walls is biased toward the north, resulting in poor seismic balance. In addition, it may not be possible to make earthquake resistance by comprehensively judging cost, construction period, consistency, and workability.

The present invention should be able to solve the problem of renewing the old buildings, which are likely to become defective stocks that buyers and borrowers do not have, into safe and flexible stocks that can flexibly respond to lifestyle changes. It is an issue.

A first aspect of the present invention is a sanitary facility installed in a space surrounded by a partition, a storage facility installed at a position facing at least a part of a wall surface of the partition, the partition and the storage facility, Provided is a multifunctional structure having a structural brace installed in a gap. Moreover, the second aspect of the present invention is an earthquake-resistant structure of a building using a multi-functional structure, and at least disposed outside the gap of the multi-functional structure installed in a living space of the building. Provided is an earthquake-resistant structure in which a pair of structural columns and the structural reinforcement are connected.

If a multi-functional structure that can use the space where structural reinforcement is installed as a load-bearing wall is installed in the living space, the multi-functional structure itself forms an earthquake-resistant core, and the earthquake-resistant balance of the building is improved. Multifunctional structures improve the construction period, consistency, and workability of building earthquake resistance, and reduce the cost of seismic reinforcement.

The structural column can be installed inside or outside the gap between the partition wall and the storage facility in accordance with the required seismic force or design requirement. When installed outside, a greater seismic force can be applied, and the ability of the multi-function structure as an earthquake-resistant core is improved. On the other hand, when installed inside, the merit in the design surface is great in that the structural pillar is not exposed.

In addition to connecting the lower end of the structural column to the foundation of the building and the upper end to the ceiling beam, the upper end is not connected to the beam but is fastened between the upper part of the multi-function structure and the beam, and the upper end is made of steel. You may make it connect. In this case, the space surrounded by the structural pillars and the steel material becomes a living space when the building collapses and serves as a shelter.

If the building is a multi-level building of either reinforced concrete, steel-framed reinforced concrete, or steel-framed, arrange the structural columns installed in each level vertically so that they can be arranged from low to high. A continuous structural column is formed, and the effect of seismic reinforcement extends to the entire building.

According to the multi-functional structure of the present invention or the earthquake-resistant structure of a building using the same, it is possible to protect the lives, body and property of the people from damage such as collapse of the building due to the earthquake, and to make the old residence The space can be transformed into a flexible living space that can respond to changes in external factors such as changes in household form and diversification of lifestyles. Members related to seismic structures such as structural reinforcements are enclosed within the multi-functional structure and hardly noticeable, so that they hardly give a feeling of pressure or discomfort as in the case of the conventional construction method.

1 includes a wash basin 12, a toilet 14, a washing machine installation base 16, a unit bath 18, a system kitchen 20, a partition wall 22, storage furniture 24, a structural pillar 26, and a structural brace 28. The overall shape is a box (box shape). The wash basin 12, the toilet 14, the washing machine installation table 16, and the unit bath 18 are installed inside the space surrounded by the partition wall 22. A wash basin 12, a toilet 14, and a washing machine installation table 16 are installed facing the largest partition 22 a among the partitions 22, and a system kitchen 20 is installed on the opposite side. A space for installing a refrigerator is provided next to the system kitchen 20.

The unit bath 18 is installed in a bathroom surrounded by four partition walls 22b, 22c, 22d, and 22e. Among these, the partition wall 22b is provided with a door 30 for going back and forth between the undressing space where the wash basin 12, the toilet 14, and the washing machine installation table 16 are installed. The remaining three partition walls 22c, 22d, and 22e are surrounded by storage furniture 24 that is arranged in a U shape in plan view. The storage furniture 24a is installed at a position facing the wall surface of the partition wall 22c with a gap 32a. Similarly, the storage furniture 24b is installed at a position facing the wall surface of the partition wall 22d, and the storage furniture 24c is installed at a position facing the wall surface of the partition wall 22e with gaps 32b and 32c. A storage furniture 24d is installed at a corner portion between the storage furniture 24a and the storage furniture 24b. In addition, storage furniture 24e is installed at a corner portion between the storage furniture 24b and the storage furniture 24c.

The structural column 26 includes three columns 26a, 26b, and 26c installed inside the multi-function structure 10, and four columns 26d, 26e, 26f, and 26g installed outside. The seven structural pillars 26a, 26b, 26c, 26d, 26e, 26f, and 26g each have a lower end connected to the foundation 34 under the floor and an upper end connected to the ceiling beam 36. A structural bracing 38a is connected to the structural column 26a and the structural column 26f. Similarly, structural struts 38b are connected to the structural columns 26b and 26c, structural struts 38c are connected to the structural columns 26c and 26e, and structural struts 38d are connected to the structural columns 26d and 26g, respectively.

The multi-function structure 40 of FIG. 2 is of the five type with two structural columns less than the multi-function structure 10 of FIG. In the multi-function structure 40, since all the structural columns 42 are installed inside the multi-function structure 40, the structural columns 42 and the structural braces 44 are not exposed at all. Accordingly, in the multi-function structure 10, the storage furniture 24 is partitioned into five places for passing the structural bracing 38 d, but in the multi-function structure 40, the storage furniture 46 only needs to be partitioned in three places.

The multi-function structure 50 in FIG. 3 is of a type in which the upper end side of the structural column of the multi-function structure 40 in FIG. 2 is short. The upper end of the structural column 52 does not reach the beam 36 but is positioned between the multi-function structure 50 and the beam 36. The upper ends are connected by a steel material 54.

The multi-function structure 60 of FIG. 4 is of a type installed in a living space of a reinforced concrete structure, a steel reinforced concrete structure, or a multi-layered structure of steel structure. The structural column 62 needs to have a greater load resistance than that of the multi-function structure 40 of FIG. 2, and the cross-sectional area increases, so that the storage furniture 64a, 64b, The depths 64c and 64d are reduced. The structural pillar 62b installed in the upper-floor living space and the structural pillar 62c installed in the lower-floor living space are positioned above and below the structural pillar 62a, and the structural pillars 62a, 62b, and 62c are vertically aligned. Install in.

FIG. 5 shows an example of a method for installing the multi-function structure. Here, in order to cope with changes in external factors such as changes in household form and diversification of lifestyles, pillars and partition walls are removed as much as possible, and multifunctional structures are added to living spaces that have become vacant. Install. As a result, the old-style living space can be transformed into a flexible living space that can respond to changes in external factors such as changes in household form and diversification of lifestyles. Members related to seismic structures such as structural reinforcements are enclosed within the multi-functional structure and hardly noticeable, so that they hardly give a sense of pressure or discomfort due to the conventional construction method. If the multi-functional structure is placed at the center of the living space, not only the earthquake resistance is greatly improved, but also a round-shaped migratory space can be created around it. A migratory space is a continuous space where people can freely come and go, not only providing a space that could not be felt in a narrow space partitioned until now, but also in the same space for individuals separated by a partition Give them the opportunity to live their lives and create a place for family communication. Furthermore, since the multi-function structure can be constructed by simply combining the factory-produced members on site, the construction period can be greatly shortened and the cost can be reduced compared to the conventional wooden shaft method.
