Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a unit type building having an elevator inside the building.

[0002]

BACKGROUND ART Elevators are usually installed in buildings such as high-rise buildings and relatively large-scale apartment buildings, but in recent years, as the number of houses has increased, detached houses have become required. There is. Then, in such a house, an upper and lower space portion (elevator shaft) reaching from the floor surface to the ceiling is formed for each floor in the same manner as in a high-rise building, and an elevating box moves up and down in the elevator shaft.

Conventionally, in order to build a building with an elevator, a construction method for making a building body and the above-mentioned elevator shaft by a frame construction method at a construction site, and JP-A-4-2377.
As shown in 74, a unit construction method is known in which a building unit and an elevator unit for each floor are separately produced in a factory, and each unit is combined at a construction site to form a building body and an elevator shaft. In this unit construction method, the elevator shaft is formed so as to be externally attached to the building body.

[0004]

However, when the elevator shaft is constructed by the conventional frame construction method as in the former case, the elevator shaft is made at the construction site for each floor, which requires a large amount of work until the completion of the building. It is time consuming and economically expensive.
On the other hand, in the latter case, since the construction is performed by the unit construction method, the problem as in the former case can be greatly improved. However, since the elevator shaft is externally attached to the main body of the building, when the site area is small, such as a house built in an urban area, there is a problem that the house cannot be built due to, for example, the building coverage ratio.

An object of the present invention is to provide a method for constructing a building with an elevator, which enables easy and quick work at a construction site and can be constructed even when the site area is small.

[0006]

A method of constructing a building with an elevator according to the present invention is intended to achieve the above-mentioned object by producing a building unit constructed so that an elevator is installed in the building in a factory. Is.

[0007] Specifically, a method of constructing a building with an elevator constructed by vertically combining a plurality of building units produced in a factory, wherein each of the building units in the plurality of building units is manufactured when the building units are produced in the factory. Characterized by forming elevator shaft constituent parts at positions corresponding to each other in a building unit and combining upper and lower building units at a construction site to form a vertically continuous elevator shaft in which an elevator box moves up and down in each elevator shaft constituent part. And

In the above, the roof of the building is formed of a combination of a plurality of roof units, and among these roof units, inside the roof unit arranged above the elevator shaft, when the roof unit is manufactured at the factory, It is desirable to install driving means for driving the lifting box up and down.

On the other hand, when the roof is formed by a combination of a plurality of roof panels, after the building units forming the elevator shaft are stacked, the driving means is installed on the ceiling of the uppermost building unit among these building units. Then
Further thereafter, roof panels may be combined to form a roof.

Alternatively, after the driving means is housed in a pit box unit installed below the elevator shaft and the pit box unit is installed at the construction site,
The building units forming the elevator shaft may be stacked directly above this pit box.

Further, a guide member for guiding the elevating box in the ascending / descending direction at the time of production of each building unit is installed in the elevator shaft constituent part, and by combining the upper and lower building units at the construction site, each guide member moves up and down in the elevator shaft. It is desirable to form a continuous guide rail.

In this case, the guide rail is formed to include a connecting member for connecting the respective guide members to each other, and the guide members are arranged in at least one of the building units which can be combined vertically when the building units are produced. It is preferable to form a continuous guide rail by attaching a connecting member between the guide members when combining the upper and lower building units.

[0013]

In the present invention as described above, since the elevator shaft components are formed in each building unit in the factory,
At a construction site, it is possible to easily form an elevator shaft that is continuous vertically by combining building units vertically. As a result, the construction time at the construction site is shortened and work efficiency is significantly improved. Further, since the elevator shaft is formed inside the building, the problem of building coverage is solved, and it becomes possible to build a building with an elevator even when the site area is small. Further, since it is not necessary to produce a unit for the elevator shaft separately from the building unit, the number of units produced in the factory can be reduced.

At this time, by installing the driving means and the guide member on the roof unit in the factory, the efficient installation work can be performed by the flow work in the factory, and the labor-intensive work at the construction site can be omitted to improve the work efficiency. Is further improved. Further, in order to form a continuous guide rail, when connecting the connecting members between the upper and lower facing guide members, the connecting members are arranged at the factory so that the connecting members are arranged at the construction site. This saves labor and enables the positioning of the connection member to be performed by a simple operation such as shifting the position of the connection member in the factory.

The connection member 17 corresponding to each guide member 12 is temporarily fixed. For temporary fixing of the connecting member 17, the bolts 19A and 19B are passed through the bolt holes of the connecting member 17, and are inserted into the long holes 18A and the temporary fixing bolt holes 18B formed in the cross member 28B, and the long holes 18A and the temporary holes are temporarily fixed. This is done by screwing nuts onto the tips of the bolts 19A and 19B protruding from the fastening bolt hole 18B. Further, the opening / closing door 14 is installed in the elevator shaft component 9. After these operations, the completed first to third floor building units 5 to 7, roof unit 8 and elevator box 1
1st class is transported by truck to the construction site.

Next, at the construction site, the foundation 4 is constructed beforehand, and the pit box unit 40 is installed in the foundation 4. Next, on this foundation 4, the building with elevator 1
A plurality of first-floor building units 5 forming one floor are arranged using a crane or the like. In this arrangement, the first-floor building unit 5A is arranged immediately above the pit box unit 40 in which the elevator is installed, and the elevating box 11 is installed in the elevator shaft forming section 9 of the first-floor building unit 5A (FIG. 2). , See FIG. 6).

On the first-floor building unit 5, the second-floor building unit 6, the third-floor building unit 7 and the roof unit 8 are provided.
