Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the construction of buildings such as RC and SRC structures.
The present invention relates to a suspension device for a temporary suspension, such as a construction lighting device, which is temporarily suspended on a ceiling part from the completion of the construction work to the completion of finishing work.

[Prior Art] FIG. 1 exemplifies a cable driving type lighting device which is most frequently used among the above construction lighting devices.

In FIG. 1, the lighting device a uses a cable c embedded in the upper floor slab b as a power source, and is connected to the cable c via an exposed electric wire d.

In the case of a double ceiling as shown, the exposed portion e of the cable c
Is extended to the lower surface side of the ceiling surface f and is connected to the exposed electric wire d at the exposed portion e.

[Problems to be Solved by the Invention]

By the way, in the case of such a cable driving type illumination device, there are the following problems.

That is, since the lighting device is necessary for finishing the wall or floor even after finishing the ceiling, in the finishing process of the entire ceiling, the finishing of the cable penetration portion is left, and when the lighting device becomes unnecessary, the lighting device is illuminated. The device a and the cable exposed part e were removed, and the double work of repairing and finishing that part was inevitable.

Generally, in the case of a double ceiling, a method has been performed in which the f ′ portion is left unattached and the illuminating device a and the cable exposed portion e are removed and the unattached portion f ′ is finished. In the case of a direct ceiling, after removing the lighting device a and the exposed cable portion e,
Methods such as concrete scrubbing of the b'part of the upper floor slab b, mortar repair, sanding, and finishing were performed. However, the time and effort required for these have been great.

In addition, the cables had to be laid between the completion of the slab spine and before the concrete was placed, so it was a short-term intensive work.

Therefore, a large number of workers are required, and the time and date are limited, so that it is not possible to arrange the desired workers.

Since the cable bur is buried in the slab, it is a one-time disposable and uneconomical.

Since the arranging position of the illuminating device a in the height direction is fixed, a stepladder is required when replacing the light bulb or repairing a damaged portion, which requires a lot of labor for maintenance.

As the temporary lighting device, in addition to the above-mentioned method, a moving lamp (such as a cabtyre cable that can be carried in a charged state) with a number of lighting devices a at equal intervals as shown in FIG. An illumination device using exposed wiring as a power source has been widely used, such as a mobile floodlight having a relatively large headlight type illumination device.

However, this is because as the ceiling construction progresses, the suspending means from the ceiling will disappear, so the suspending means will be sought or removed from the wall part, and after that, it will be dependent only on the above cable driven lighting device. It had the following problems.

That is, when the light bulb approaches the wall surface, the finish material is discolored by heat, and when it is a combustible material, it may cause a fire.

When relying on the above cable driven lighting system, it is difficult to secure sufficient illuminance.Therefore, in finishing work requiring a certain level of illuminance, workers individually install mobile lighting systems such as hand lamps and floodlights. There is a high risk of power outages, fires, electric shocks, etc. due to the large number of devices that pose a safety hazard as they are carried and carried around.

The present invention has been made to solve the conventional problems as described above, and the purpose thereof is to provide a lighting device that is temporarily suspended from the upper floor slab from the frame work to the completion of the finishing work. It is an object of the present invention to provide a suspension device for a temporary suspended object capable of suspending.

[Means for Solving the Problems]

The suspension device of the temporary suspension according to the present invention is fixed and hung down to a fixing member provided on the lower surface of the upper floor slab of the building under construction, and the cutting part has a pattern of the surrounding ceiling surface and It consists of a thin wire with a thickness that is assimilated to unevenness, and a combined body that is slidable with respect to the thin wire and is not slipped by frictional force.
A temporary suspension used in a building under construction is hung on the combined body.

[Action]

In the present invention, the fixing member provided on the lower surface of the upper floor slab of the building under construction does not become a visible failure in the normal living state in which the cut portion is assimilated to the pattern or unevenness of the surrounding ceiling surface. Hanging a thin wire.

The thin wire is provided with a coupling body that is slidable with respect to the thin wire and is prevented from slipping by frictional force.

Then, the combined body can suspend the temporary suspension.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a sectional view specifically showing a case where the present invention is applied to a Suzuran lamp.

In the figure, 1 is an upper floor slab 1 and 2 is an upper floor slab 1
It is a Suzuran lamp that is temporarily suspended.

The Suzuran lamp 2 has a structure in which a large number of lighting fixtures 2'are arranged at predetermined intervals on a power supply line 4 having a connector plug 3 connected to a distribution board at one end.

Then, the power supply line 4 is suspended by the thin wires 5 arranged at a predetermined distance on the lower surface side of the upper floor slab 1 to be suspended on the upper floor slab 1.

The fine wire 5 has no rusting property, color developing property, or corrosive property, and is made of, for example, Tegus material in a coil shape, and is integrated with a fixing member 6 embedded in the lower surface side of the upper floor slab 1. There is.

As shown in FIG. 4, the fixing member 6 has a concave cross section, and the thin wire 5 is reduced and stored with its upper end tied to the tongue piece 8 in the recess 7.

The fixing member 6 is prevented from coming off from the upper floor slab 1 by a flange-shaped projection 9 formed around the upper end.

To embed the fixing member 6 in the upper floor slab 1, as shown in FIG. 4, nails 11 are attached to the slab form 10 at the completion of the form work.
It may be temporarily fixed by using such as.

Further, the power supply line 4 and the thin line 5 are connected by a connecting pair 12, 12 'as shown in FIGS.

These coupling bodies 12 and 12 ′ are slidable with respect to the thin wire 5, and a thin wire coupling portion 13 with which the thin wire 5 is anti-slip coupled with the thin wire 5 and a power supply wire 4 are connected. A coupling portion 14 is provided.

In the case of the combined body 12, the thin wire connecting portion 13 is a notch gap capable of giving a sufficient frictional force with the thin wire 5, and the power supply wire connecting portion 14 has a clip structure and is integrally made of a synthetic resin material. It is configured.

Further, in the case of the combined body 12 ', the thin wire connecting portion 13' is a through hole having a frictional force, and further, the frictional force is increased by tightening with the connecting band 12'a, and the power supply line connecting portion 14 'is a string with hooks at the end of the coupling band 12'a that is coupled to the thin wire coupling section 13'.

In the case of the combined body 12, it is provided on the power supply line 4 side in advance (it is arranged at a position corresponding to the lighting device 2 ′). Therefore, when connecting the power supply line 4 to the thin wire 5, only the thin wire connecting portion 13 side needs to be connected. in this case,
The fine wire 5 can obtain an appropriate frictional force by selecting and penetrating the cut gaps of the fine wire connecting portion 13 at 2 to 4 places, and the power supply line 4 can be slid and coupled by being prevented from slipping. Has been done.

In the present invention, the combined body is not limited to the above-mentioned one, and various structural changes can be made.

When the construction work progresses and the construction work shown in FIG. 2 shifts to the construction of the ceiling wall 15 shown in FIG. 3, the power supply is arranged so that the combined body 12 (or 12 ′) is located on the lower surface side of the ceiling wall 15. Lower line 4.

In this case, for example, a telescopic operation rod 16 as shown in FIG.
With, you can easily do it on the floor without using a stepladder.
That is, the sandwiching portion 17 at the upper end of the operating rod 16 is connected to the combined body 1
When the thin wire connecting portion 13 or 13 'is inserted into the 2 (or 12') connecting portion 18 and pulled downward, the thin wire connecting portion 13 or 13 'slides down while being pressed against the thin wire 5 by frictional force.

In constructing the ceiling wall 15, the thin wire 5 is arranged at the joint portion.

In the case of a double ceiling as shown in the example, after removing the Suzuran lamp 2,
Since the fine wire 5 remains on the ceiling wall 15, this is cut. At this time, the cut surface of the thin wire 5 remains, but it is so small that it is not visually useless under normal living conditions.

Further, in the case of a straight ceiling having only the upper floor slab 1, the concave portion 7 of the fixing member 6 is stuffed and finished with the fine wire 5 in the process of the groundwork. After removing the Suzuran lamp 2, the thin wire 5 is cut. At this time, since the cut surface of the thin wire 5 is very small, it does not become a visible failure in a normal living state as in the case of the double ceiling, and therefore, it is not necessary to carry out finishing repair.

8 and 9 show different embodiments.

FIG. 8 shows a case where the upper end of the thin wire 5 ′ is tied and fixed to the equipment pipe 19 attached to the lower surface of the upper floor slab 1 ′.

Further, FIG. 9 shows a case where the lower end of the thin wire 5 ″ is connected to the power supply wire 4 ′ and the thin wire 5 ″ and the power supply wire 4 ′ are directly connected without using a connecting body.

The structure of FIG. 8 can be applied to a building which is not an RC structure, and the structure of FIG. 9 is adopted when the temporary suspended object (power supply line 4 ′) is relatively heavy.

〔The invention's effect〕

In short, the present invention is a thickness that the cut portion is assimilated to the pattern or unevenness of the surrounding ceiling surface finish, which is fixed and hung down to the fixing member provided on the lower surface of the upper floor slab of the building under construction. Of the fine wire and a combined body that is slidable with respect to the thin line and is prevented from slipping by frictional force.
Since it is configured to suspend the temporary suspension used in the building under construction, it is easy to attach the thin wire to the upper floor slab and at the same time the thin wire interferes with the worker who passes the lower floor. There is no. In addition, the temporary suspension can be easily re-stocked, so that the temporary suspension can be placed at a height position that does not interfere with various operations on the lower floor, and the temporary suspension can be prevented from being damaged. When such an operating rod is used, there is an advantage that maintenance such as exchanging a ball can be facilitated without using a stepladder.
