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 three-story unit building in which an elevator device is installed.

[0002]

2. Description of the Related Art A conventional building with an elevator is described, for example, in Japanese Patent Application Laid-Open No. 7-309551. What is described in the above publication is a multi-storey unit building configured by combining a plurality of building units,
An elevator space is provided on the upper and lower floors and serves as an elevator room, and the components of the elevator apparatus are factory-installed in each building unit in a building unit production factory.

[0003]

However, in the unit building with an elevator described in the above-mentioned publication, the elevator space serving as the elevator room has a stairwell and no scaffolding. There is a problem that joining is difficult. Further, even if a stepladder or the like is used as a scaffold, it can only reach the height of the first floor.

The present invention has been made in view of the above problems, and has as its object to provide a method for constructing a unit building in which building units can be easily joined in an elevator space.

[0005]

According to the first aspect of the present invention,
In a construction method of a unit building in which a car of an elevator device is installed so as to be able to move up and down in an elevator space communicating with the first to third floors of a three-story unit building,
Temporarily installing elevator cars in a building unit with a floor space and an elevator space, stacking the first to third floor building units up and down at the construction site, and joining the building units using the top surface of the car as a foothold It is characterized by performing.

According to a second aspect of the present invention, in the method for constructing a unit building according to the first aspect, a component including a car of the elevator apparatus is factory-attached to the building unit at a building unit production factory. And

(Action) According to the first aspect of the present invention,
The elevator car is temporarily installed in the building unit that has the elevator space and constitutes the second floor of the unit building, and the building units on the first to third floors are piled up and down at the construction site, and then the building is built with the top surface of the car as a scaffold. Since the connection between the units is performed, the connection between the building units on the second floor or the third floor is facilitated.

According to the second aspect of the present invention, since the components including the car of the elevator apparatus are attached to the building unit at the building unit production factory, the construction period at the construction site can be shortened. it can.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view showing an embodiment of the present invention and showing a method of constructing a unit building. In FIG. 1, reference numeral 1 denotes a unit building. The unit building 1 is a three-story building, and a first-floor building unit 11 installed on a building foundation 2 and a first-floor building unit 11 A second-floor building unit 12 to be installed;
It comprises a third-floor building unit 13 installed on the second-floor building unit 12, and a roof unit 14 installed on the third-floor building unit 13. Each of the building units 11 to 13 constituting the unit building 1 is a panel type in which a wall panel is erected on the periphery of a floor panel, but a frame assembly in which a frame is assembled by columns and beams. It may be of a formula.

The unit building 1 is provided with an elevator space 3 communicating with the first to third floors. In the elevator space 3, a car 4 of an elevator apparatus which can be moved up and down is installed. In addition, the elevator space 3 includes each building unit 1.
It is formed by opening 1 to 13 floor panels.

[0011] The components of the elevator apparatus are produced at the production factories of the building units 11 to 13, and these building units 11 to 13 are provided.
13 is factory attached. The constituent members of the elevator apparatus include, in addition to the car 4, landing door units attached to the building units 11 to 13 on each floor, guide rails of the car 4, elevators for the car 4, and the like. The lifting device of the elevator device may be any of a hydraulic jack type and a suspension type using a wire. When the lifting device is a hydraulic jack type, the hydraulic jack may be attached to the first-floor building unit 11, and a hydraulic drive unit for driving the hydraulic jack may be attached to any of the building units.

In the method of constructing the unit building 1 of the present embodiment, the elevator equipment car 4 is temporarily supported and installed in the building unit 12 constituting the second floor of the unit building 1 and having an elevator space. Keep it. After the building units 11 to 13 on the first to third floors and the roof unit 14 are piled up and down at the building site, joining between the building units is performed using the upper surface of the car 4 as a scaffold as follows.

Reference numeral 51 denotes a building foundation 2 and a first-floor building unit 11
Numeral 52 indicates a junction between the first-floor building unit 11 and the second-floor building unit 12. Also, 53
Denotes a joint between the second-floor building unit 12 and the third-floor building unit 13, and 54 denotes a joint between the third-floor building unit 13 and the roof unit 14. Since the joining portion 51 is immediately adjacent to the building foundation 2, the joining operation can be easily performed. In the joining operation of the joining portion 52, the stepladder 6 is installed on the ground on which the building foundation 2 is provided, and the joining operation is performed on the stepladder 6. The work of the joint 53 is performed on the upper surface of the car 4, and the work of the joint 54 is performed by setting the stepladder 6 on the car 4 and riding on the stepladder 6.

According to the present embodiment, the elevator car 4 is temporarily supported and installed in the building unit 12 which constitutes the second floor of the unit building 1 and has an elevator space. Building units 11 to 1 on the first to third floor
After stacking the roof unit 14 and the roof unit 14 up and down and joining the building units using the upper surface of the car 4 as a scaffold, 2
The connection between the building units 12, 13 on the floor or the third floor is facilitated.

Further, the components including the car 4 of the elevator apparatus are supplied to the building units 11, 1 and 1 at the production factory.
Since the factories 2 and 13 are factory-installed, the construction period at the construction site can be shortened.

FIG. 2 shows a comparative example in comparison with the above embodiment. FIG. 2A shows a construction method of a unit building in which the car 4 is temporarily installed in the first-floor building unit 11, and FIG. It is explanatory drawing which shows the construction method of the unit building in which the car 4 was temporarily installed in the 3rd-floor building unit 13. As shown in FIG. 2 (a), when the car 4 is installed on the first-floor building unit 11, the stepladder 6 is installed on the car 4, and the third-floor building unit 13 and the roof unit 14 are placed on the stepladder 6. Is inaccessible to the joint 54 of In addition, as shown in FIG.
Is installed in the third-floor building unit 13, the joining work of the joining portion 54 can be performed using the upper surface of the car 4 as a scaffold, but the joining portion 53 of the second-floor building unit 12 and the third-floor building unit 13 is provided.
Is not accessible even if the stepladder 6 is set on the ground.

[0017]

According to the first aspect of the present invention, an elevator car is temporarily installed in the building unit on the second floor,
Since the joining between the building units is performed using the upper surface of the car as a scaffold, the joining between the building units is facilitated, and can be performed safely and efficiently.

According to the second aspect of the present invention, since the components including the car of the elevator apparatus are attached to the building unit at the building unit production factory, the construction period at the construction site can be shortened. it can.
