Abstract

PROBLEM TO BE SOLVED: To make any vibration isolable from a structure without installing a special joint, simplifying the piping work, thereby facilitating the base isolation in a small building by securing a piping structural body to foundation and raising it upright, while separating the vibration from the building, and supporting a pipeline from the outdoors on the structural body through the foundation part. SOLUTION: Plural units of base isolation devices 3 of base isolating rubber and suchlike are set up at each of specified positions on a concrete foundation 2 built on the ground 1, and a building 4 is mounted on the base isolation devices 3 in a separated state from the foundation 2 and vibrations. In succession, a piping structural body 5 is constituted by a wall composing a core, and this structural body 5 is built upright on the foundation 2. The structural body 5 and the building 4 are made into separated state by arranging specified clearance 6 between them, by way of example, so as not to restrain each other in time of an earthquake. A pipeline 7 from the outdoors is introduced into the structural body 5 after piercing through the lower part of a side wall of the structural body 5 through a side part of the foundation 2 from the ground 1, and is installed rising upright to the inside of the structural body 5 from the foundation 2.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a piping structure for a base-isolated building.

[0002]

2. Description of the Related Art Conventionally, as a seismic isolation building, as shown in FIG. 3, a seismic isolation device 103 such as seismic isolation rubber is interposed between a foundation 101 and a building 102. As a structure for installing electric wires, gas pipes, water pipes, drain pipes and the like (hereinafter referred to as pipes) such as facilities in such a seismic isolation building, FIG.
As shown in (1), there is a construction in which a pipe 104 from the outside penetrates through the foundation 101 to the lower part of the floor of the building 102, and further, penetrates through the floor plate of the building from the lower part of the floor into the building 102.

[0003]

In the above seismic isolation building, the foundation 101 largely shakes with the ground 105 in an earthquake or the like, whereas the building 102 is
By the base 101 and the building 102
And relatively move relatively. Therefore, in the above-described piping structure, it is necessary to connect the piping 104 in the lower part of the floor and the piping 104 in the building 102 with a flexible joint 106 that can withstand large deformation. However, there is a problem that it is difficult to cope with the problem, and it is a bottleneck for seismic isolation in a small building or the like, and it is necessary to consider the durability of the joint 106.

Accordingly, an object of the present invention is to provide a piping structure of a seismic isolation building which solves the above problems.

[0005]

In order to solve the above-mentioned problems, the invention according to claim 1 is directed to a seismic isolation building in which a building is constructed by interposing a seismic isolation device on a foundation. The present invention is characterized in that the body is fixed to the foundation and started up, the building and the edge are cut off against vibration, and piping from outside is supported by the structure through the foundation.

In the present invention, during an earthquake, the building vibrates in a state of being cut off with respect to the ground, the foundation and the structure. Further, the ground, the foundation and the structure vibrate integrally. Furthermore, piping installed in the structure from the ground outside through the foundation,
Vibrates integrally with the ground, foundation and structure.

Therefore, even if the foundation and the building move relatively, the piping is not affected by the vibration of the building.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described based on the embodiment shown in FIGS. Figure 1 shows the first
An example will be described.

In FIG. 1, a plurality of seismic isolation devices 3 such as seismic isolation rubbers are set at predetermined positions on a concrete foundation 2 constructed on a ground 1, and a building 4 is mounted on the seismic isolation device 3.
It is placed in an edged state against vibration.

FIG. 1 shows an example in which a core is provided in a building. A wall constituting the core constitutes a structure for piping, and this structure 5 is fixed to the foundation 2. It is built up. The structure 5 and the building 4
Means that, for example, a predetermined gap 6 is provided between them so that they are not constrained to each other during an earthquake.

A pipe 7 from the outside is introduced into the structure 5 from the ground 1 through the lower part of the side wall of the structure 5 through the side of the foundation 2 and is introduced into the structure 5 from the base 2 part. The facility is standing up. When the structure 5 is a core, a facility such as a kitchen is installed in the core,
The above pipe 7 is connected to this facility.

In the above configuration, if the foundation 2 vibrates together with the ground 1 during an earthquake, the building 4 is isolated by the seismic isolation device 3. Moreover, since the piping structure 5 is fixed to the foundation 2 and the piping 7 is supported by the foundation 2 and the structure 5, the piping 7 is cut off from the building 4 together with the foundation 2 and the structure 5. Vibrate.

Therefore, even if the foundation 2 and the building 4 are relatively moved by the earthquake, the piping 7 is not affected by the vibration of the building 4. Therefore, it is not necessary to provide the flexible joint 106 in the pipe 7 as in the conventional case.

Further, as in the above embodiment, the structure 5
In addition, by arranging electric wires, gas pipes, water pipes, drain pipes, etc. and wiring and piping as described above, facilities are gathered in one place, maintenance is easy to manage, and furthermore, In such a way that facilities are concentrated, wiring,
The construction cost can be reduced by shortening the piping route.

FIG. 2 shows a second embodiment. In the second embodiment, a counter or partition wall of a kitchen or the like is formed by a structure 5a for piping, instead of the core type as in the above embodiment. This structure 5a is also fixed to the foundation 2 in the same manner as in the first embodiment, and is cut off from the building 4.
Then, a gas appliance 8 or the like 8 is provided in the structure 5a, and piping is provided to this. Since other structures are the same as those of the first embodiment, the same portions are denoted by the same reference numerals and description thereof will be omitted.

The second embodiment has the same functions and effects as those of the first embodiment. The structure for piping is
In the first embodiment, the core is used as the core, and in the second embodiment, the counter is used as a counter. Alternatively, the structure may be dedicated to the piping.

As described above, the present invention can be applied to the case of wiring an electric wire. For the sake of explanation, the present invention includes this wiring as a generic term and does not exclude the wiring. .

[0018]

As described above, according to the present invention,
Since it is not necessary to provide a special joint in the piping as in the conventional case, the piping is facilitated, and the seismic isolation of the small building is facilitated. Furthermore, there is no need to consider the durability of the joint as in the related art.

Furthermore, by concentrating the wiring and piping on the piping structure, the facilities are concentrated in one place, the maintenance can be easily managed, and the wiring and piping routes can be shortened, thereby reducing the construction cost. Reduction can also be achieved.
