DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for installing a construction elevator which is attached to a building under construction and used for transporting workers and building materials while the height of the building is gradually increased as the construction proceeds. In particular, the present invention relates to a method of installing a construction elevator using a main article which is left in a building even after completion of construction work and is used as a main elevator.

[0002]

2. Description of the Related Art In recent years, buildings have been raised to a higher floor due to deregulation and effective use of land, while steelwork of buildings has been assembled to the top floor at building construction sites in order to improve the efficiency of building work due to labor shortages. Instead of installing the elevator after completion, when the steel frame rises to the middle floor, a construction elevator is temporarily installed in the building and used for transporting building workers and small materials, and progress of building construction As the steel frame of the building becomes higher, the method of increasing the elevator ascending and descending steps and increasing the service floor of the elevator is increasing.

As a conventional construction elevator, a rise-up elevator mainly composed of temporary articles is generally used as shown in FIG. In this method, an elevator shaft 1 is constructed in a building under construction, and a receiving beam 2 is temporarily installed on the upper halfway floor in the hoistway 1 so as to lie on a beam 3 of the building. Machine room 4 is placed and held. This temporary machine room 4 is of a small size designed to be able to move up and down the hoistway 1 sequentially by a crane or the like. In this machine room 4, a hoisting machine 5 for temporary articles and an elevator operation control panel 6 are installed. It is stored compactly. Further, a temporary rope 7 is wound around a hoisting sheave of a hoisting machine 5 in the temporary machine room 4 and hangs downward, and a temporary car 8 and a counterweight 9 are suspended via the temporary rope 7. They are suspended in the hoistway 1 and are moved up and down by the drive of the hoisting machine 5 so that construction workers and small articles can be transported.

[0004] However, in the conventional elevator system for construction mainly using temporary articles, although it is convenient during the construction period, the steel frame of the building is completed to the top floor,
At the time of installing the permanent elevator, it is necessary to remove the temporary equipment and then install the permanent equipment.The removal work and the installation work take a lot of time and effort, and during the work period, Operation service is not available, which is inconvenient. In addition, there is a drawback in that a large amount of cost is required to use a large number of temporary articles, resulting in a rise in construction costs.

[0005] Therefore, as a measure to solve the disadvantage,
There is a method of installing a construction elevator proposed in Japanese Patent Publication No. 52-2177. In this method, as many temporary equipment as possible are used, the removal of the temporary equipment is omitted, and the elevator machine room equipment for the temporary installation is distributed and stored in a plurality of containers. Containers are arranged in the hoistway and are moved up and down as the construction work progresses.

[0006]

By the way, in the above-mentioned proposed method of installing a construction elevator, since a large number of permanent installations are used, it is relatively easy to make a final transition to the permanent elevator. Elevator machine room supplies (mechanical equipment supplies such as hoisting machines and electric control equipment supplies such as elevator operation control panels) are installed together so that they can be moved up and down in narrow hoistways. It is extremely difficult to arrange the elevator machine room supplies in a plane in the hoistway, and it is extremely difficult to distribute and store them in a plurality of containers as described above and stack them in a plurality of stages. Must be densely arranged in the hoistway. For this reason, the number of containers is large, the arrangement in the hoistway and the ascending and moving work are troublesome, and there is no room in space, so that maintenance and inspection of the machine room supplies are difficult.

[0007] Even if each container of the machine room supplies is waterproofed, rainwater enters the hoistway because the upper part is open during construction, and guide rails, various detectors and the like in the hoistway are provided. Rainwater is applied to the equipment such as a car and a counterweight, and when the construction work is completed, damage and stains are severe, causing a problem that the elevator cannot be used as a permanent elevator.

Further, the construction site often has a high-temperature and high-humidity environment, and there is an inconvenience that electrical control equipment such as a board of an elevator operation control panel, which is sensitive to such environmental conditions, causes trouble.

The present invention has been made in view of the above circumstances,
The purpose of the above is to easily install and move the elevator machine room supplies for complicated main construction such as control, as well as to allow sufficient space for maintenance and inspection, and finally, It is an object of the present invention to provide a construction elevator installation method using a permanent installation, which makes it easy to shift to a permanent elevator.

A second object is to provide not only elevator machine room articles for main construction but also articles in the hoistway sufficient for waterproofing against rainwater and the like during construction work, and to prevent damage and contamination. Another object of the present invention is to provide a method of installing a construction elevator using a main article, which can finally be used as a main elevator as it is.

A third object of the present invention is to use the main equipment which can prevent the trouble of the electric control equipment such as the board of the elevator operation control panel even in the environment of a high-temperature and high-humidity construction work site. It is an object of the present invention to provide a construction elevator installation method.

[0012]

According to a first aspect of the present invention, there is provided a method of installing an elevator for use of a construction equipment using a permanent installation in a building under construction in order to achieve the first object. Along with the construction of the hoistway, mechanical equipment such as a hoist and electrical control equipment such as an elevator operation control panel among elevator machine room supplies for main construction are separated and unitized, and the mechanism is constructed. While installing the equipment supply unit at an appropriate position above the hoistway, installing the electric control equipment supply unit on the building side adjacent to the equipment supply unit, and attaching a rope wrapped around a hoist of the mechanism equipment supply unit. A car and counterweight for permanent installation are installed in the hoistway so as to be able to be driven up and down in the hoistway, and while using as an elevator for construction in this state, as the building becomes higher due to the progress of building work, the mechanical device Product units are sequentially transferred to the upper part of the hoistway, and the electrical control device supply units are sequentially transferred to the upper floors of the building. The present invention is characterized in that a control device article is relocated.

According to such an installation method, among the equipment for the elevator machine room for complex installation such as control, the equipment for the mechanical device such as the hoist can be easily installed as one unit in the hoistway of the building under construction. On the other hand, electric control equipment such as an elevator operation control panel can be easily installed as a separate unit on an adjacent building floor or the like, and the space for installing them can be easily provided, so that maintenance and inspection can be facilitated. In addition, the mechanical equipment supplies and the electric control equipment supplies can be easily relocated upward along with the progress of construction work for each unit, and can be easily used as a construction elevator. Finally, by transferring the mechanical device supplies and the electric control device supplies to the permanent elevator machine room at the top of the building, they can be used as a permanent elevator in a short period of time.

According to a second aspect of the present invention, in the above-described method of installing a construction elevator using the main equipment, a rain shield for covering the upper surface of the mechanical equipment supply unit is provided in the hoistway of the building under construction. There is no rainwater or the like entering the hoistway during construction, and sufficient waterproofing measures are taken, and not only the above-mentioned mechanism device supplies in the hoistway, but also other hoistway goods such as cars and various switches. Since it does not get wet with rainwater or the like and rainwater or the like does not enter the hoistway, electric control equipment installed on the adjacent building side is less likely to get wet with rainwater or the like. As a result, there is no possibility that the various main articles are damaged or soiled during use as the construction elevator, and the final article can be finally used as it is without any trouble.
