Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building with an elevator in which an elevator is newly installed in an existing building.
[0002]
[Prior art]
Under the current Building Standard Law, when installing an elevator in a building, the building is required to have considerable earthquake resistance. Buildings built before the enforcement of the current Building Standard Act are generally earthquake-resistant. The majority of genders do not meet the standards of current law.
[0003]
Therefore, it is not possible to install an elevator in an existing wooden structure. In order to install an elevator, the existing building must be removed and then reconstructed to meet the above earthquake resistance standards. It was.
[0004]
[Problems to be solved by the invention]
In recent years, in Japan, an aging society has been greeted, and there is a growing demand for installing elevators for homes in buildings with more than two stories. The elevator could not be installed.
[0005]
And in order to install an elevator, the building has to be reconstructed, and the cost is great, and it is general that the installation of the elevator has to be given up.
[0006]
Further, for example, a living area is expanded by reconstructing a two-story existing building as it is to a three-story building, and accordingly, the necessity of installing an elevator is further increased.
[0007]
In order to solve the above-mentioned problem, the present inventor has invented a method for extending a space upward without destroying an existing building (see Japanese Patent Application No. 11-126220).
[0008]
However, as described above, an elevator cannot be installed in an existing building due to the problem of earthquake resistance, and even if it is extended upwards at a low cost, there may be cases where sufficient effects cannot be obtained depending on the home. was there.
[0009]
In view of the problems of the conventional technology, the present invention can be installed without demolishing and rebuilding the existing building even if the existing building does not satisfy the seismic standards of the current law at present. The building with an elevator provided with the elevator which can be provided is provided .
[0010]
[Means for Solving the Problems]
In the first invention, a first steel column extending in the vertical direction and a steel beam extending in the horizontal direction fixed to the first steel column are provided so as to surround the outside of the existing building. A recess is cut in the existing building, and a second steel column extending in the vertical direction is erected in the recess, and the second steel column is a third steel column for a stud with a steel beam. A shaft in which an elevator moves in a vertical direction is formed in a space surrounded by the third steel column for the stud and the second steel column, and the elevator is vertically disposed inside the shaft. The new structure is constructed by the first steel column, the second steel column, the third steel column, and the steel beam, and the new structure is the existing building. is an elevator with buildings, characterized in that it is mechanically isolated from the
[0011]
The second invention is the building with an elevator according to claim 1 , wherein the new structure satisfies an earthquake resistance standard in the Building Standard Law .

FIG. 9 is a longitudinal sectional view as seen from the front side, FIG. 10 is a layout diagram in which the elevator is installed inside , and FIG. 11 is a layout diagram in which the elevator is installed on the outer side.
[0014]
First, a construction method related to the present invention will be described with reference to FIGS.
[0015]
FIG. 1 shows an existing general two-story building, which includes a first floor part 1 and a second floor part 2, and a roof member 3 provided at the upper part in the vertical direction of the second floor part 2. . There are neighbors on the left and right.
[0016]
In order to extend the third-floor portion 9 to such an existing two-story building, first, as shown in FIGS. 1 and 2, an existing foundation made of concrete having an inverted T-shaped section is shown. On the outside of 4, a new foundation 5 made of inverted L-shaped concrete that matches with the existing foundation 4 is combined and provided. In addition, the said foundation 5 does not need to be continuous and may be provided partially.
[0017]
Next, a steel column 6 made of, for example, 125 mm × 250 mm H-shaped steel having a length corresponding to the height of the first floor portion 1 is fixed to the new foundation 5 with anchor bolts 7.
[0018]
Wherein the upper end of the steel column 6 extends in the horizontal direction, it is fixedly provided by unillustrated bolts or the like steel beam 14 made of the same H-shaped steel and the steel columns 6.
[0019]
A steel column 6 made of H-shaped steel having a length corresponding to the height of the second-floor portion 2 is fixed to the upper portion of the steel beam 14 with a bolt or the like (not shown), and the steel frame of the third-floor portion 9 is the same as described above. The beam 14 and the steel column 6 are constructed, and the third floor portion 9 is expanded.
[0020]
As a construction method for alternately laminating and constructing the steel column 6 and the steel beam 14 as described above, for example, there is a so-called “β system construction method” of Sekisui House Co., Ltd.
[0021]
Next, a new roof member 8 is constructed on the upper part of the steel beam 14, and a tile part such as a color vest 10 is mounted on the upper surface of the roof member 8.
[0022]
During this time, the resident can continue to live in the first floor portion 1 and the second floor portion 2.
[0023]
Thereafter, the existing roof member 3 indicated by hatching in FIG. 5 is removed, and the steel beam 11 on the floor portion of the third floor portion 9 is attached as shown in FIG. 6, and finally the third floor portion as shown in FIG. The floor member 12 is mounted on the upper part of the steel beam 11 of the floor portion 9, and the wall member 13 is mounted on the outside of the steel column 6.
[0024]
As described above, when the existing roof member 3 is removed, a new roof member 8 is already provided above the roof member 3, so that rain or the like does not enter the second floor portion 2.
[0025]
Accordingly, even during the above-described extension work, a resident resident in the first floor part 1 or the second floor part 2 can continue to live in the same state.
[0026]
In addition, when removing the existing roof member 3 and mounting the floor member 12 of the third floor portion 9, the resident of the second floor portion 2 needs to retreat , but the existing roof member 3 is removed, The period for installing the floor member 12 of the third floor portion 9 is sufficient for three to four days if it is a normal house, and only during this period, residents living in the second floor portion 2 are on the first floor. You only have to live in part 1.
[0027]
In the present embodiment, since the side walls of the first floor portion 2 and the second floor portion 2 are doubled, the heat insulation effect, the sound insulation effect, and the like of the portion are improved.
[0028]
On the other hand, if the heat insulation efficiency and the like are not necessarily emphasized, the construction cost can be reduced by omitting the wall member 13.
[0029]
Then, to FIG. 8 to the aspect of the embodiment where a major portion of the present invention will be described with reference to FIG. 10.
[0030]
Note that the same parts as those shown in FIGS. 1 to 7 are denoted by the reference numerals shown in these drawings, and detailed description thereof is omitted. 8 and 9, the existing building is represented by A, and the building after the extension is represented by B.
[0031]
First, in FIG. 8, a recess 17 is cut in the left central portion of an existing building A, and a steel column 6 a as a support portion extending in the vertical direction is erected in the recess 17.
[0032]
The steel column 6a is fixed to a steel column 6b for a stud by a steel beam (not shown).
[0033]
A shaft (elevator shaft hole) 15 in which the elevator 16 moves in the vertical direction is formed in a space surrounded by the steel column 6b for the intermediate column and the steel column 6a. Configured to move in the direction.
[0034]
The elevator 16 itself is generally a small household product sold by an elevator manufacturer and distributor, and can be installed if the horizontal cross-sectional area (installation area) of the shaft 15 is about 1 square meter. Reference numeral 18 in FIG. 9 denotes an elevator pit.
[0035]
The structure (the building B after the extension) by the steel columns 6, 6a, 6b and the steel beam 14 is mechanically insulated from the existing building A, and the stress generated in the existing building A Has a structure that does not propagate to the structure B after extension.
[0036]
In addition, the earthquake resistance of the structure B after the extension satisfies the earthquake resistance standard of the Building Standard Act at the time of extension.
[0037]
Therefore, the elevator 16 will be installed in the building B after extension that satisfies the seismic standards, and even if the existing building A does not meet the seismic standards in the Building Standard Act at the time of extension, installation of the elevator Is possible.
[0038]
Incidentally, as shown in FIGS. 8 to 10, it is also possible to provide a shaft 15 for an elevator 16 in the interior of the existing building A. FIG. 11 is a reference example in which a shaft 15 for an elevator 16 is provided on the outer side of an existing building A.
[0039]
Moreover, although this Embodiment adds space to the upper part of the existing building, it does not necessarily need to be extended and naturally, it is also possible to install only an elevator in the existing building. is there.
[0040]
【The invention's effect】
In the first invention, since the elevator is installed in a new structure that is mechanically insulated from the existing building , even if the new structure satisfies the seismic standards of the current Building Standards Act Even if an existing building does not satisfy the seismic standards under the current Building Standards Act, it is possible to install an elevator inside the building.
[0041]
Therefore, even if the existing building itself does not meet the seismic standards of the current Building Standards Act, an elevator can be installed at a low cost without removing the building and rebuilding it. You can contribute a lot.
[0042]
In the second invention, the new structure satisfies the seismic standards under the Building Standards Act, so even if the building itself does not meet the seismic standards according to the current Building Standards Act , An elevator can be installed.
