Description

[Detailed description of the invention] [Industrial application field]

TECHNICAL FIELD The present invention relates to a method for installing a lighting fixture, and more particularly to a method for suspending it from a ceiling slab and installing it on a lower ceiling member.

[Conventional technology]

In the conventional lighting equipment installation method, as shown in FIG. 3, when pouring and forming a ceiling slab 3, an insert 6 for growing a female thread is provided at a desired position on the lower surface, and a fully threaded bolt 7 is inserted into the insert 6. By screwing one end together and screwing the lighting fixture 2 onto the other end, it is suspended and installed in the opening 51 of the ceiling member 5.

[Problem to be solved by the invention]

However, in the above-mentioned conventional lighting fixture installation method, the lighting fixture 2 can only be installed directly under the insert 6 provided in the ceiling slab 3 because the lighting fixture 2 is suspended and installed using a straight fully threaded bolt 7. Ta. In other words, it was necessary to place the insert 6 with good positional accuracy in accordance with the installation position of the lighting fixture 2 when forming the pouring of the ceiling slab 3, but in actual construction, there may be misalignment of the shank or adjustment with the ceiling joint. The installation position of the lighting fixture 2 often needs to be changed. In such a case, it is necessary to recast the insert 6 and install the lighting fixture 2, which poses a problem in that construction efficiency is reduced. Further, there was also the problem that the installation work itself of the lighting fixture 2 using the fully threaded bolts 7 was troublesome and complicated. Therefore, there has been a need for a lighting fixture installation method that can easily accommodate changes in the installation position of the lighting fixture 2 and that can perform installation work efficiently.

[Means to solve the problem]

The present invention has been made in order to solve the above-mentioned problems of the prior art, and the lighting equipment inserted into the opening of the ceiling member is suspended by a bendable suspension means whose one end is fixed to the slab reinforcement of the ceiling slab above. This is a method of installing lighting equipment characterized by hanging it.

[Effect]

In the present invention, a lighting fixture inserted into an opening in a ceiling member is suspended and installed by a bendable suspension means whose one end is fixed to the slab reinforcement of an upper ceiling slab. Even if the fixing position of the hanging means to the ceiling slab is considerably shifted in the horizontal direction, the lighting fixture can be installed at a predetermined position by hanging diagonally without changing the fixing position of the hanging means.

【Example】

Next, the present invention will be explained in detail based on an illustrated embodiment. Reference numeral 1 denotes a suspension means made of bendable stainless steel wire with a diameter of 1.5 mm, one end 11 of which is fixed to the slab reinforcement 31 of the ceiling slab 3, and the lighting fixture 2 suspended from the free end 12 side. ing. As a method of fixing one end 11 of the suspension means 1 to the slab reinforcement 31 and pulling out the other free end 12 from the lower surface of the ceiling slab 3, a small ring 14 is formed at one end with a crimp sleeve 13, and the other end is attached to the shaft 14. Pass the slab muscle 31 through the ring 15 formed through the end and tighten it, and then tighten the free end 12.
There is a method of casting concrete 32 by rolling it into the bottom of a formwork for pouring a ceiling slab (not shown), removing the formwork, and stretching the suspension means 1 exposed on the lower surface of the ceiling slab 3. . The free end 12 of the suspension means 1, whose one end 11 is fixed to the slab reinforcement 31 in this way, is passed through the fixing hole 21 of the lighting fixture 2, and furthermore, a metal fitting, such as a commercially available slide lock 4, is attached to the free end 12. To install the lighting fixture on the ceiling member 5 installed below the ceiling slab 3 (usually 30 to 50 cm below), insert the lighting fixture 2 into the opening 51 and push up the slide lock 4. , the member 42 that receives the thumbscrew 41
When screwed in, the body portion 43 tightens the suspension means 1 from around it and fixes it immovably. Therefore, the lighting fixture 2 is installed in the opening 51 of the ceiling member 5 without falling below the slide lock 4. When suspending and installing the lighting fixture 2 using the suspension means 1, the position at which the suspension means 1 is pulled out from the ceiling slab 3 is the opening 5.
The lighting fixture 2 can be hung and installed in the opening 51 by appropriately shifting the fixing position of the slide lock 4 downward, not only when it is on the center of the lighting fixture 1, but also when it is shifted considerably in the horizontal direction. I can do it. When the pull-out position of the hanging means 1 and the opening 51 are misaligned in the horizontal direction and the lighting fixture 2 is hung diagonally by the hanging means 1, the lighting fixture 2 is placed only on the end face of the opening 51 on the pull-out position side. Since it will be pressed against you, it is usually desirable to hang it at an angle of up to 45 degrees. However, when the ceiling member 6 is made of a high-strength member, it is also possible to hang it at an angle exceeding 45 degrees. In order to prevent the lighting fixture 2 suspended and installed in the opening 51 by the suspension means 1 from abnormally vibrating and breaking in the event of an earthquake, etc., a conventionally known fixing means (not shown) is installed. This does not preclude the use of the hanging means 1 in combination and the close fixation to the opening end of the ceiling member 5, and there are no limitations on the material, structure, or connection method with the lighting fixture 2 of the hanging means 1. It can be changed as appropriate depending on the structure of the lighting fixture 2, etc.

【Effect of the invention】

As explained above, the method of installing the lighting equipment according to the present invention is as follows:
This lighting equipment installation method is characterized by suspending a lighting equipment inserted into an opening in a ceiling member by a bendable suspension means with one end fixed to the slab reinforcement of an upper ceiling slab. Not only are inserts that had to be placed accurately in line with the joints of ceiling components, and fully threaded bolts that took time to screw together, not only are there no longer any need for them, but the suspension means that one end is fixed to the slab ribs allows for diagonal suspension. Therefore, it is possible to easily deal with misalignment, design changes, etc. Therefore, it is possible to quickly install lighting fixtures in accordance with the joints of ceiling members, etc., and it has become possible to significantly improve construction efficiency.
