When renovating an existing office building, ceiling renewal work is sometimes carried out only on weekends and other holidays when the office is not in operation to update or repair the ceiling while the office is in operation. In ceiling renewal work, it is necessary to perform electrical work such as removing lighting fixtures as equipment-side work before starting construction work on the existing ceiling. This is because the lighting equipment must be installed safely by a professional electrician. However, if the ceiling renewal work is not completed in one weekend but is carried out over multiple weeks, it will be necessary to temporarily restore the lighting equipment at the end of each holiday in preparation for the office's working days, that is, weekdays. . This is because even if the ceiling panels were removed and only a lightweight base was left, as long as it was cleaned and there was some lighting, it could still be used as a living room. However, ceiling work is not equipment work, but is mainly construction work performed by carpenters, interior decorators, painters, etc., and electrical work is carried out every weekend just to temporarily restore lighting equipment. Become. In this way, installing and removing lighting fixtures multiple times during the ceiling renewal construction period results in an increase in the number of workers, which is inefficient.

The present disclosure has been made in view of the above-mentioned problems, and the purpose of the present disclosure is to provide a temporary installation method that allows ceiling lighting equipment to be temporarily installed continuously during the construction period in ceiling renewal work. shall be.

In order to solve the above-mentioned problems, the first disclosure uses hanging bolts to move an existing lighting fixture, in which a base or a reflector parting is installed at the ceiling surface of a ceiling board, to a position lower than the ceiling surface. Applies to temporary installation methods for temporary installation. The temporary installation method consists of a preparation process to prepare a fully threaded bolt, a hanging bolt and a long nut to be screwed into the fully threaded bolt, a removal process to remove the lighting fixture from the hanging bolt, and a process to remove the fully threaded bolt using the long nut. and a temporary installation step of temporarily installing the lighting device on the tip side of the fully threaded bolt.

The second disclosure further includes the following features in the first disclosure.

Embodiments of the present disclosure will be described below with reference to the drawings. However, in the embodiments shown below, when referring to the number, amount, amount, range, etc. of each element, unless it is specifically specified or it is clearly specified to that number in principle, such reference shall be made. This disclosure is not limited to that number. Furthermore, the structures and the like described in the embodiments shown below are not necessarily essential to this disclosure, unless specifically specified or clearly specified in principle.

Embodiment.
1. Configuration of the lighting device applied to the embodiment FIG. 1 is a perspective view of an example of the lighting device applied to the embodiment, viewed from the office floor side. FIG. 2 is a partial cross-sectional view of the illumination device taken along the -Y direction in the figure. FIG. 1 shows a part of the internal structure behind the ceiling of an existing office building as seen through. The lighting device includes a plurality of existing lighting fixtures 10. The lighting fixture 10 is a fluorescent lamp or an LED ceiling-mounted light. For example, in the case of a buried lighting fixture, a parting part ( In the case of a buried type, a reflector (parting part of the reflector) is attached to the edge of the opening and installed. For example, V-shaped lighting fixtures are installed by joining the ends of the base to predetermined ceiling board positions. Each lighting fixture 10 is supported from a building structure, such as an upper floor floor slab, by a pair of hanging bolts 12, respectively. The pair of hanging bolts 12 are fully threaded bolts (also called threaded bolts) for suspending the lighting fixture 10 from the ceiling slab 14 of the building. The pair of hanging bolts 12 are fixed to the ceiling slab 14 at their proximal ends, and to the lighting fixture 10 at their distal ends. Although FIG. 2 shows an example in which the lighting fixture 10 is embedded in the ceiling board 20 (embedded lighting fixture), it can also be a V-shaped lighting fixture or a single fixture that is installed on the ceiling surface of the ceiling board 20. good. A plurality of such lighting fixtures 10 are installed at intervals on the office floor of an existing office building. In addition, in the figure, the X direction shows the longitudinal direction of the lighting fixture 10, the Y direction shows the lateral direction of the lighting fixture 10, and the Z direction shows the height direction.

2. Configuration of Temporary Installation Device of Embodiment Ceiling renewal work to repair and update the ceiling board 20 on the office floor of an existing office building may be performed. Ceiling renewal work will be carried out with office floors closed on specific days such as weekends. In ceiling renewal work, electrical work is first performed to temporarily remove electrical equipment such as lighting fixtures, and then architectural work is carried out to renew the ceiling. However, if the ceiling renewal work is to be carried out over multiple weeks, it will be necessary to temporarily restore lighting fixtures that can achieve a predetermined illuminance for work on the office floor during the weekday period until the next weekend.

Now, let us consider that electrical work is carried out every weekend, in which electrical equipment is removed at the beginning of the weekend period during which construction work is performed, and then temporarily restored at the end of the weekend period. For example, if the ceiling renewal work takes two months, a total of 16 days of electrical work will be required to remove and temporarily restore the electrical equipment.

Therefore, the temporary installation device 4 of this embodiment is a device devised for the purpose of temporarily installing the lighting fixture 10 at a position on the ceiling that will not interfere with construction work. The position where ceiling construction work is not hindered is, for example, a position where the vertically downward distance from the ceiling surface of the ceiling board 20 is 200 mm or more and 300 mm or less. If the distance between the ceiling board 20 and the base of the lighting equipment or the end of the reflector is 200 mm or more, there will be sufficient vertical distance between the newly installed lightweight frame bracket and the new ceiling board, and construction work will be easier. It does not get in the way of the craftsmen's handling of tools and materials to be installed. Further, the temporary installation position of the lighting fixture 10 is preferably at a height where people on the office floor do not come into contact with it. Such a height is, for example, a position where the vertically upward distance from the floor surface of the office floor to the lower end of the lighting fixture 10 is 2 m or more.

FIG. 3 is a diagram for explaining the configuration of the temporary installation device 4. As shown in FIG. Moreover, FIG. 4 is a perspective view showing an example in which the temporary installation device 4 is applied to a lighting device. The temporary installation device 4 includes a fully threaded bolt 6 and a long nut 8. The thread diameter and thread pitch of the fully threaded bolt 6 are preferably the same as those of the suspension bolt 12. For example, the thread diameter of the fully threaded bolt 6 is W3/8. This is because the thread diameter of a fully threaded bolt used for the hanging bolt 12 of equipment in the ceiling is W3/8 unless the item is extremely heavy. Further, the length of the fully threaded bolt 6 is a length that satisfies the above conditions for the temporary installation position, and is, for example, 200 mm or more and 300 mm or less.

The long nut 8 is a hexagonal nut having a thread diameter and a thread pitch that are screwed into the hanging bolt 12 and the fully threaded bolt 6. The long nut 8 connects the suspension bolt 12 and the fully threaded bolt 6 by screwing the tip of the suspension bolt 12 from one end and screwing the base end of the fully threaded bolt 6 from the other end. . For example, the long nut 8 has a thread diameter of W3/8 and a length of 40 mm.

3. Method for temporarily installing a lighting fixture using a temporary installation device for a lighting device Next, a working procedure of a method for temporarily installing a lighting device 10 using a temporary installation device for a lighting device according to an embodiment will be described in detail. FIG. 5 is a partial cross-sectional view of the lighting device temporarily installed using the temporary installation device 4, as viewed along the -Y direction in the figure. Hereinafter, a work procedure of a temporary installation method for one of the plurality of lighting fixtures 10 will be illustrated, but the same applies to the other lighting fixtures 10.

3-1. Preparation process:
If the lighting fixtures 10 are installed on a pair of hanging bolts 12 suspended from an insert in a ceiling slab or the like, a temporary installation including two full-thread bolts 6 and two long nuts 8 for each lighting fixture 10, respectively. Prepare device 4.

3-2. Removal process:
The lighting fixture 10 is bolted to a hanging bolt 12. The worker removes the lighting fixture 10 from the hanging bolt 12 and also removes the electrical wiring of the lighting fixture 10. As a result, the tips of the hanging bolts 12 are exposed in the openings 22 of the ceiling board 20.

3-3. Connection process:
The worker screws one end of the long nut 8 onto the tip of the suspension bolt 12, and screws the other end into the base end of the fully threaded bolt 6. Thereby, the tip of the suspension bolt 12 and the base end of the fully threaded bolt 6 are connected in a straight line.

3-4. Temporary installation process:
The worker temporarily installs the lighting fixture 10 on the tip of the fully threaded bolt 6 using the bolt used to fix the lighting fixture 10 to the hanging bolt 12. Thereby, the lighting fixture 10 is placed at a lower position by the length of the fully threaded bolt 6. As a result, the installation height h1 of the lower end of the lighting fixture 10 from the ceiling surface is, for example, 200 mm or more and 300 mm or less, and the installation height h2 of the lower end of the lighting fixture 10 from the office floor is, for example, 2 m or more. The worker also connects electrical wiring to the lighting fixture 10. Existing electrical wiring has extra length in the ceiling, and will be extended below the ceiling level while remaining connected to the base electrical distribution board. Thereby, the lighting fixture 10 is temporarily installed in a state where it can be used as temporary lighting.

On the office floor after the lighting equipment 10 has been temporarily installed in the temporary installation process, ceiling construction work is performed on office holidays, and normal office operations are performed on office work days. The temporarily installed lighting fixture 10 is used as temporary lighting for the office floor.

3-5. Removal process:
When the ceiling construction work is completed, the worker removes the temporarily installed lighting fixture 10 and temporary installation device 4. Here, the lighting fixture 10 and the temporary installation device 4 are removed by performing the reverse procedure of the temporary installation process and the connection process.

3-6. Installation process for new lighting equipment:
The worker connects the electrical wiring to the new lighting fixture and fixes the new lighting fixture to the hanging bolt 12. If the lighting equipment is of the same type, the base of the lighting equipment or the parting part of the reflector plate will be neatly joined to the new opening 22 which has the same size as the existing opening 22. In addition, in order to make it easier to replace existing old-style fluorescent lighting fixtures with highly energy-saving LED lighting, lighting equipment manufacturers are producing replacement LED lighting fixtures with the same shape to provide the same illuminance. In the case of a replacement LED lighting fixture, the base of the lighting fixture or the parting part of the reflector plate is neatly joined to the new opening 22 having the same dimensions as the existing opening 22.

4. Functions and Effects of Temporary Installation Method for Lighting Equipment According to the temporary installation method using the temporary installation device 4 as described above, the following functions and effects can be obtained.

The lighting fixture 10 temporarily installed at a position lower than the ceiling surface by the temporary installation device 4 can function as temporary lighting during construction and during operation of the office floor. Thereby, even if the construction work on the ceiling is carried out over the office working days, the trouble of attaching and detaching the lighting fixture 10 each time can be saved. In particular, by temporarily installing the lighting fixture 10 at a height of 200 mm to 300 mm below the ceiling surface, it is possible to prevent interference with ceiling construction work. This eliminates the need for temporary lighting especially during the construction period and allows for the reuse of existing equipment. In addition, the lighting fixture 10 is temporarily installed so that the distance from the office floor surface to the bottom end of the lighting fixture 10 is 2 m or more to prevent people on the office floor from coming into contact with the lighting fixture 10. I can do it.

The fully threaded bolt 6 of the temporary installation device 4 has the same thread diameter and the same thread pitch as the hanging bolt 12. Thereby, the lighting fixture 10 can be fixed to the fully threaded bolt 6 by the same method as that used for fixing it to the hanging bolt 12. Further, since the existing lighting fixture 10 scheduled for disposal can be used as temporary lighting, there is no need to worry about stains, scratches, etc. on the lighting fixture 10 during the construction period.

The lighting fixture 10 temporarily installed by the temporary installation device 4 serves as a guide for a new opening for a new lighting fixture to be newly installed during ceiling construction.

The fully threaded bolts 6 and long nuts 8 of the temporary installation device 4 can be reused in other construction work.

5. Modified Example of Temporary Installation Method for Lighting Fixtures The method for temporarily installing lighting fixtures according to the embodiment may be modified as follows.

There are no limitations on the dimensions of the fully threaded bolt 6 and long nut 8 of the temporary installation device 4. That is, the length of the fully threaded bolt 6 can be set as appropriate depending on the height of the ceiling surface of the office building. Further, the thread diameter or thread pitch of the fully threaded bolt 6 does not necessarily need to be the same as that of the hanging bolt 12. However, if the thread diameter or thread pitch of the fully threaded bolt 6 is different from that of the hanging bolt 12, half of the long nut 8 from one end is screwed into the fully threaded bolt 6, and half from the other end is screwed into the hanging bolt 12. The nut may be configured as a combination of two types of thread diameters or thread pitches so as to be screwed together.

In addition, the ceiling this time is a light ceiling, in other words, the openings etc. are assumed to be a conventional light ceiling with light steel studs, a field edge holder, and a board ceiling, but this is not limited to this. A similar configuration can be applied to a system ceiling that is fitted into a field fence or the like.
