Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a method of installing a construction elevator that is attached to a building under construction and is used to transport workers, construction materials, etc. while gradually raising the elevator as the construction progresses. In particular, the present invention relates to a construction elevator installation method using permanent equipment that is left in a building and used as a permanent elevator even after construction work is completed.

0002

[Background Art] In recent years, buildings have become taller due to the relaxation of laws and regulations and the effective use of land.In order to improve construction work efficiency due to labor shortages, steel frames of buildings are assembled up to the top floor at construction sites. Rather than installing elevators after construction is completed, a construction elevator is temporarily installed in the building once the steel frame has been erected to the middle floor, and is used for transporting construction workers and small materials, as well as for the progress of construction work. As the steel frames of buildings become taller, there is an increasing number of systems in which the vertical travel of elevators is increased to increase the number of floors serviced by elevators.

As shown in FIG. 2, a conventional construction elevator is generally a rise-up elevator mainly made of temporary equipment. This involves constructing an elevator hoistway 1 in a building under construction, temporarily installing a receiving beam 2 horizontally on a beam 3 of the building halfway up the hoistway 1, and temporarily installing a receiving beam 2 on top of the receiving beam 2. The machine room 4 for use is placed and held. This temporary machine room 4 is of a small size designed so that it can be moved up and down the hoistway 1 sequentially using a crane or the like. Stores compactly. In addition, a temporary rope 7 is wound around the hoisting sheave of the hoist 5 in the temporary machine room 4 and hangs downward, and a temporary car 8 and a counterweight 9 are connected via the temporary rope 7. They are suspended in the hoistway 1 and moved up and down by the drive of a hoist 5 to transport construction workers, small materials, and the like.

[0004] However, although the conventional construction elevator system, which mainly uses temporary equipment, is convenient during the construction period, once the steel frame of the building has been completed to the top floor,
When installing a permanent elevator, the temporary equipment must be removed and the permanent equipment must be installed after that, which requires a lot of effort and time to remove and permanently install. It is inconvenient that there is no operational service. In addition, the use of many temporary supplies increases costs, leading to a rise in construction costs.

[0005] Therefore, as a measure to eliminate this drawback,
There is a method for installing a construction elevator proposed in Japanese Patent Publication No. 52-2177. This method attempts to omit the removal work of temporary equipment by using as many permanent equipment as possible.Elevator machine room equipment for permanent installation is distributed and stored in multiple containers, and these multiple Containers are placed inside the hoistway and moved up and down as construction work progresses.

[0006]

[Problems to be Solved by the Invention] By the way, in the above-mentioned proposed construction elevator installation method, many permanent equipment items are used, so that it is relatively easy to eventually transition to a permanent elevator. The equipment in the elevator machine room, which is complex to control, etc. (mechanical equipment equipment such as hoisting machines, and electrical control equipment equipment such as elevator operation control panels) is compacted and installed so that it can be moved upwards in a narrow hoistway. In particular, it is impossible to arrange these elevator machine room items horizontally in the hoistway, so as mentioned above, they are distributed and stored in multiple containers and stacked in multiple tiers. shall be placed closely together in the hoistway. For this reason, there are a large number of containers, and it is troublesome to arrange them in the hoistway and move them up and down, and there is not enough space, making it difficult to maintain and inspect the equipment in the machine room.

Furthermore, even if each of the containers for machine room supplies is waterproofed, the upper part of the hoistway is open during construction, so rainwater enters the hoistway and damages the guide rails, various detectors, and other parts of the hoistway. Rainwater splashes on the main equipment such as the car and counterweight, and by the time the construction work is completed, the damage and stains are so severe that the elevator becomes unusable.

Furthermore, construction sites are often in hot and humid environments, and there is an inconvenience that troubles may occur with electrical control equipment components such as boards for elevator operation control panels that are sensitive to such environmental conditions.

[0009] The present invention was made in view of the above circumstances, and its first aspect is
The purpose of this is to make it easy to install and move up and down the equipment in the elevator machine room for complex main installations such as controls, and to make maintenance and inspection easier by freeing up space. To provide a method for installing a construction elevator using permanent supplies, which allows easy transition to a permanent elevator.

[0010] The second objective is to ensure that not only the equipment in the elevator machine room for the main installation but also the equipment in the hoistway are sufficiently waterproofed against rainwater during construction work, and protected to prevent damage and staining. To provide a method for installing an elevator for construction using equipment for construction, which ultimately allows the elevator to be used as a construction elevator as it is.

[0011] The third objective is to use built-in equipment that can prevent problems with electrical control equipment equipment such as boards for elevator operation control panels even in the high temperature and humid environment of construction sites. The purpose of the present invention is to provide a construction elevator installation method.

[Means and effects for solving the problem] In order to achieve the first object, the method for installing a construction elevator using permanent equipment according to the first invention is to install an elevator for construction use in a building undergoing construction work. Along with constructing the hoistway, mechanical equipment such as the hoisting machine and electrical control equipment such as the elevator operation control panel were separated into units among the elevator machine room equipment for the main installation, and the mechanical equipment was divided into units. While the equipment equipment unit is installed at an appropriate position above the hoistway, the electrical control equipment equipment unit is installed on the side of an adjacent building, and a rope wrapped around the hoisting machine of the mechanical equipment equipment unit is installed. A car and a counterweight for the main installation are installed in the hoistway so that they can be driven up and down, and in this state, while being used as a construction elevator, the mechanical equipment equipment unit will be raised and lowered as the building becomes taller as construction work progresses. At the same time, the electrical control equipment supplies units will be sequentially relocated to the upper floors of the building, and finally the mechanical equipment supplies and electrical control equipment supplies will be moved to the upper floor of the building, in the elevator machine room for permanent installation. It is characterized by relocating.

[0013] With this installation method, mechanical equipment such as the hoisting machine among the elevator machine room equipment for complicated main installation such as controls can be easily installed in the hoistway of the building under construction as one unit. At the same time, electrical control equipment such as elevator operation control panels can be easily installed on the floor of an adjacent building as a separate unit, and maintenance and inspection are facilitated because there is plenty of space for their installation. In addition, the mechanical equipment and electrical control equipment can be easily moved upward one by one as the construction work progresses, making it possible to conveniently use the elevator as a construction elevator. Finally, by moving the mechanical equipment and electrical control equipment to the permanent elevator machine room in the upper part of the building, the elevator can be used as a permanent elevator in a short period of time.

[0014] The second invention is, in the above-mentioned construction elevator installation method using permanent equipment, by providing a rain shelter to cover the upper surface of the mechanical equipment equipment unit in the hoistway of the building under construction. Waterproofing measures are sufficient to prevent rainwater from entering the hoistway during construction, and to ensure that not only the mechanical equipment and supplies in the hoistway, but also other hoistway supplies such as cars and various switches, etc. Since there is no chance of getting wet with rainwater or the like, and since rainwater or the like does not enter the hoistway, electrical control equipment installed on the side of an adjacent building will also be less likely to get wet with rainwater or the like. This prevents the various main installation supplies from being damaged or soiled during use as a construction elevator, and allows them to be used as a main construction elevator without any problems.

[0015] The third invention is that in the above-mentioned construction elevator installation method using permanent equipment, temperature and humidity sensors are provided in the electrical control equipment equipment unit during building construction, and signals from these sensors are used to control the temperature and humidity inside the unit. By being equipped with an air conditioner that maintains temperature and humidity within a certain range,
Even under the high temperature and high humidity environment of a construction site, it is possible to improve the environment for the electrical control equipment and supplies, and to prevent the occurrence of troubles with electrical components such as circuit boards that are sensitive to high temperature and high humidity environments.

[0016]

[Embodiment] An embodiment of the method for installing a construction elevator using the present equipment will be described below with reference to FIGS. 1(a), (b), and (c). First, as shown in FIG. 1(a), an elevator hoistway (elevator shaft) 11 for permanent installation is constructed in a building under construction. When the building reaches an appropriate floor height, the receiving beam 12 is temporarily installed at an appropriate floor position in the elevator hoistway 11 so as to be suspended horizontally on the beam 13 of the building. In addition, among the elevator machine room supplies for the main installation, the hoisting machine 14a
Mechanical equipment parts 14 such as the like and electrical control equipment parts 15 such as the elevator operation control panel 15a are separated into 14A and 1, respectively.
Unitize as shown in 5A. The mechanical equipment and supplies unit 14A has a structure in which various mechanical equipment and supplies 14 are housed in a compact frame so that it can be pulled up into the hoistway 11 by a crane or the like, and ultimately easily disassembled. Further, the electrical control device supplies unit 15A
This also has a structure in which various electrical control items 15 are housed in a compact frame so that they can be moved to the upper floor and finally easily disassembled. The mechanical equipment equipment unit 14A is installed on the receiving beam 12 in the hoistway 11, while the electrical control equipment equipment unit 15A is installed on the floor 16 of an adjacent building at the same height as this.
Install A.

In this state, the mechanical equipment equipment unit 1
A rope 17 is wound around the hoisting sheave of the 4A hoisting machine 14a and hangs down inside the hoistway 11. A car 18 for main installation is suspended from one end of the rope, and a car for main installation is suspended from the other end of the rope. A counterweight 19 is suspended, and the car 18 and the counterweight 19 are installed in the hoistway 11 so that they can be driven up and down.

In the figure, 20 and 21 are guide rails for the car and counterweight attached to the hoistway 11, and 22 and 23 are shock-absorbing buffers erected at the bottom of the hoistway 11. . All of these are for the actual installation. Further, in the figure, 24 is a construction scaffold, and 25 is a moving scaffold.

The installation of the construction elevator to the lower floors is thus completed. In this state, the electrical control device article 15
The hoisting machine 14a of the mechanism equipment 14 is controlled by
The car 18 and the counterweight 19 are raised and lowered into the hoistway 11 through the rope 17 by the rotational drive of the elevator, and the elevator is operated as a construction elevator and used for transporting construction workers and small materials.

At this time, a rain shelter 26 is temporarily installed in the hoistway 11 to cover the upper surface of the mechanical equipment equipment unit 14A. This rain shelter 26 is a waterproof curing plate and is installed horizontally inside the hoistway 11 so as to cover it. With this, rainwater etc. from above the building during construction work can be removed from the rain shelter 26 inside the hoistway 11.
It prevents rainwater from entering further downwards, and prevents rainwater from getting wet by rainwater, etc., on each mechanical equipment 14 of the mechanical equipment equipment unit 14A, other equipment in the hoistway such as the car 18, counterweight 19, and various switches. In addition, floor 1 on the building side where the electrical control equipment supplies unit 15A is installed.
It also prevents rainwater etc. from entering the hoistway 11 into the hoistway 6.

[0021] Also, the electrical control equipment supplies unit 15
The floor 16 on the side of the building where A is installed is made up of most of the walls of the surrounding buildings, so there is little intrusion of rainwater. The unit 15A is covered with a waterproof covering 27 such as a waterproof cover, and a temperature and humidity sensor 28 is provided inside the unit 15A, and the temperature and humidity inside the unit 15A are maintained and controlled within a certain range based on signals from these sensors 28. It is equipped with an air conditioner (not shown) such as a cooler. This makes it possible to improve the environment of the electrical control device equipment 15 even under the high temperature and humid environment of a construction site.

[0022] Next, as mentioned above, when the construction elevator, which had been serving the lower floors, was to be raised to the middle floors as the building became taller as construction work progressed, it was first temporarily installed in the hoistway 11. Remove the rain shield 26. In addition, the hoistway 11 will be increased in height. In this state, Figure 1(b)
As shown in FIG.
etc. to lift it above the hoistway 11. At this time, the receiving beam 12 is temporarily removed. In addition, the counterweight 19 is lowered to the lower end inside the hoistway 11, and the car 18 is suspended from the lower part of the mechanical equipment equipment unit 14A by a wire or the like.
Remove rope 17. In this state, the mechanical equipment equipment unit 14 is lifted and moved together with the car 18 to a position on the middle floor, and there, the receiving beam 12 is again placed horizontally on the beam 13 to hold the mechanical equipment equipment unit 14 on the rack. on the other hand,
Since the electric control equipment supplies unit 15A is separated from the mechanical equipment supplies unit 14, it is not necessary to lift this electric control equipment supplies unit 15A alone in the hoistway 11, and other lifting lifts (not shown) are required. ) and then transported and relocated to the middle floor 16a of the building.

FIG. 1(c) shows the hoisting sheave of the hoisting machine 14a of the mechanism equipment unit 14A relocated to the middle floor in this way.
As shown in FIG. 1, a long rope 17a is wound around the car, and the car 18 and the counterweight 19 are suspended from the rope 17a. This makes it possible to operate as a construction elevator up to the middle floor, and the rain shelter 26 that covers the upper surface of the mechanical equipment equipment unit 14A in the hoistway 11 is temporarily installed again, and the temperature inside the electrical control equipment equipment unit 15A is Humidity is maintained within a certain range using an air conditioner.

[0024] Furthermore, when the building becomes taller and rises to a higher floor due to the progress of construction work, the same procedure as described above is carried out. Finally, when the steel frame and other structures of the building have been assembled to the top floor, an elevator machine room (not shown) for permanent installation will be provided at the top of the building, and the mechanical equipment equipment unit 14A will be pulled up into this machine room. While dismantling the unit, various mechanical equipment items 14 such as the hoisting machine are installed in predetermined positions, and the electrical control equipment equipment unit 15 is also carried into the machine room and dismantled, and each electrical equipment equipment equipment 15 is installed as it is.
Install it in the specified location. This will enable it to operate as a permanent elevator.
