Description

The present disclosure relates to a wiring fixing tool and a wiring fixing method, and particularly to a wiring fixing tool and a wiring fixing method in the ceiling of a suspended ceiling structure.

In living rooms such as general office buildings, commercial facilities, hospitals, and buildings where ceilings are laid even in factories, downlights that are lighting equipment for electrical equipment, emergency lighting, heat detectors for automatic fire alarm equipment that is disaster prevention equipment, etc. In many cases, small external equipment such as smoke detectors are installed so that they can be seen from under the ceiling. Although it is a conventional method, due to its versatility, a field edge is assembled on the base of the gypsum board, which is a ceiling board, as a lightweight steel ceiling base, and a field edge holder is assembled in a shape orthogonal to it, and hung from under the upper floor slab with a field edge receiving hanger. Ceilings that are used as ceiling bases with hanging bolts are common. In the case of this ceiling, only the foundation is hung and laid first as a building work, and then electric cables and communication cables are laid as equipment work. In the subsequent process, the gypsum board ceiling board will be installed on the construction side, and the ceiling will be closed once with the ceiling board. After that, the ceiling board is opened at a predetermined position in the equipment construction, and the electric cable and communication cable in the ceiling laid at the time of the ceiling foundation construction and the equipment installed under the ceiling are attached while connecting from under the ceiling. ..

And a mounting part that is arranged on the rear end side with respect to the temporary fixing part and to which a cable is attached. The detector is configured to be able to pass through the wiring hole when it is pulled indoors from a state where it is temporarily fixed in the wiring hole. According to such a configuration, the position of the wiring hole can be specified from the indoor side by the magnet. Furthermore, it is said that the cable can be passed through the wiring hole by pulling out the detected tool temporarily fixed to the wiring hole to the indoor side.

Japanese Patent No. 6616914

The technique of Patent Document 1 is premised on providing a wiring hole at the field edge. However, the electrical equipment (equipment) provided on the ceiling is not always installed at the position of the field edge. Further, when the electric device is an embedded lighting device or the like, the field edge overlapping with the mounting position may be cut to secure a mounting space. In this case, if the equipment has an outer shape larger than the width of the field edge, the wiring hole cannot be installed on the field edge. In addition, if a wiring hole is opened in the field edge that is in close contact with the ceiling plate, the wiring hole and the ceiling plate opening must exactly match, and it is not possible to temporarily fix the wiring by holding the wiring in the field edge with another member. It is possible. As described above, the technique of Patent Document 1 has a problem in fixing the end portion of the wiring to the ceiling at an arbitrary planned installation position of the electric device without being restricted by the arrangement of the field edge in the ceiling. be.

This disclosure has been made in view of the above-mentioned problems, and is a wiring fixture and wiring that can fix the wiring of the electric equipment installed on the ceiling near the planned installation position behind the ceiling. The purpose is to provide a fixing method.

In order to solve the above-mentioned problems, the first disclosure is fixed to a plurality of field ceiling receivers installed at intervals from each other in the superstructure of the building frame via a plurality of suspension members and a plurality of field ceiling holders.

The third disclosure further has the following features in the first or second disclosure.
The call line is configured to be wound in a direction orthogonal to the pair of field edge receivers.

The fourth disclosure further has the following features in any one of the first to third disclosures.
The fixing structure includes a binding member that bundles the end portions, and is configured to hook and fix the portion bound by the binding member to the calling line.

The fifth disclosure further has the following features in any one of the first to third disclosures.
The fixing structure includes a connector member fixed to the end portion, and is configured to be fixed through a calling wire to a closed loop formed by the connector member and wiring.

Further, in order to solve the above-mentioned problems, the sixth disclosure is fixed to a plurality of field ceiling holders installed at intervals from each other in the upper structure of the building frame via a suspension member and a plurality of field edge holders. At the ceiling of a suspended ceiling structure with a plurality of field edges and a ceiling board attached to the underside of the field edges, the end of one or more wires for electrical equipment to be installed on the ceiling board. Is applied to the wiring fixing method for fixing the ceiling board before mounting. The wiring fixing method consists of a specific process for specifying the planned installation position of electrical equipment, and a winding process for winding a call wire between a pair of field edge receivers sandwiching the planned installation position among multiple field edge receivers. It comprises a fixing step of fixing the end portion to the nominal line using a fixing structure. In the winding process, the call wire is wound so as to pass directly above the planned installation position. Further, in the fixing step, the end portion is fixed so as to be directly above the planned installation position.

The seventh disclosure further has the following features in the sixth disclosure.
The winding process is configured so that the call wire is wound around the nearest field edge receivers located on both sides of the planned installation position.

The eighth disclosure further has the following features in the sixth or seventh disclosure.
The winding step is configured to wind the calling wire in a direction orthogonal to the pair of field edge receivers.

The ninth disclosure further has the following features in any one of the sixth to eighth disclosures.

According to the wiring fixture and the wiring fixing method of the present disclosure, in the ceiling of the suspended ceiling structure before the ceiling board is attached, the end of the wiring of the electric device to be installed on the ceiling board is the position where the electric device is planned to be installed. It is fixed so that it is located directly above. Therefore, according to the present disclosure, the end portion of the wiring of the electric device can be easily pulled out from the opening opened at the planned installation position after the ceiling board is attached. In addition, the nominal wire of the wiring fixture is wound around the field edge holder. Therefore, according to the structure of the wiring fixture of the present disclosure, the end portion of the wiring of the electric device is directly above the planned installation position at any planned installation position of the ceiling board without being affected by the arrangement of the field edge. It becomes possible to fix it. As represented by LED lighting that has become widespread since the 2011 Great East Japan Earthquake, under-ceiling visible equipment has become smaller. For example, if the downlight is an incandescent lamp and the outer diameter of the fixture is about 150 mm, you can search for a cable that is temporarily fixed by inserting the worker's hand into the ceiling from under the ceiling of a hole opened later on the ceiling board. rice field. However, in recent miniaturized LED downlight fixtures, for example, the ceiling board opening is about 60 mm and it is impossible to insert a hand, so it is not possible to fix the end of the wiring of the electrical equipment directly above the planned installation position. It's very important.

In particular, according to the second and seventh disclosures, the call wire is wound around the nearest field edge receivers located on both sides of the planned installation position. This makes it possible to suppress slack and misalignment of the wound call wire.

Further, according to the third and eighth disclosures, the calling wire is wound in a direction orthogonal to the pair of field edge receivers. According to such a winding structure, it is possible to suppress the occurrence of slack due to the misalignment of the nominal wire.

Embodiment.
1. 1. Schematic Structure of Lightweight Steel Ceiling FIG. 1 is a diagram showing an outline of a suspended ceiling structure to which the wiring fixture according to the embodiment is applied. The suspended ceiling structure 100 is, for example, a structure of a lightweight steel-framed ceiling in a steel-framed building. Note that FIG. 1 is an excerpt of a part of the suspended ceiling structure 100 seen from the indoor side. The suspended ceiling structure 100 includes a hanging bolt 8, a hanger 10, a field edge receiver 12, a field edge 14, and a ceiling board.

The suspension bolt 8 is suspended from the superstructure (upper slab) H of the building frame. The suspension bolt 8 is attached to, for example, an insert provided in the superstructure H. In the example shown in FIG. 1, four suspension bolts 8 are shown.

A hanger 10 is attached to the lower end of each hanging bolt 8. The hanger 10 supports the field edge receiver 12. That is, the suspension bolt 8 and the hanger 10 function as a suspension member for suspending the field edge receiver 12 from the superstructure H.

The field edge receiver 12 is for supporting the field edge 14. A plurality of field edge receivers 12 are installed at predetermined intervals so as to be parallel to each other. FIG. 1 illustrates two field edge receivers 12.

The field edge 14 is for supporting the ceiling board 16. A plurality of field edges 14 are attached to the field edge receiver 12 by using a clip material (not shown). The plurality of field edges 14 are installed in parallel with each other at intervals in a direction orthogonal to the longitudinal direction of the field edge receiver 12. In FIG. 1, four field edges 14 are illustrated.

The ceiling board 16 constitutes the ceiling surface of the space on the indoor side. The ceiling board 16 is, for example, gypsum board. The ceiling board 16 is attached to the lower surface side of the plurality of field edges 14 so as to cover the entire suspended ceiling structure 100. FIG. 1 schematically shows a part of the ceiling board 16 attached to the suspended ceiling structure 100. In the following description, the space above the ceiling board 16 is referred to as "attic A1", and the space below is referred to as "indoor space A2".

Electrical equipment such as lighting equipment and fire alarms are installed on the ceiling board 16. FIG. 1 shows, as an example, the embedded lighting device 18 installed on the ceiling board 16. FIG. 2 is a schematic cross-sectional view of the suspended ceiling structure cut at a vertical surface perpendicular to the field edge holder at the installation position of the lighting equipment. As shown in this figure, an opening 161 is provided in the ceiling board 16 at the installation position of the lighting device 18. The opening 161 is for embedding and fixing the lighting device 18. Wiring W1 for the lighting device 18 is routed near the installation position in the attic A1 of the suspended ceiling structure 100. When performing electrical work to install the lighting equipment 18, the worker opens an opening 161 at the planned installation position. Then, the worker pulls out the wiring W1 from the opening 161 and connects it to the lighting device 18, and then installs the lighting device 18 in the opening 161.

2. 2. Characteristics of Wiring Fixtures According to the Embodiment When installing electrical equipment on the ceiling board 16, the following problems may occur. FIG. 3 is a diagram for explaining a problem when installing an electric device on a ceiling board. Among the electric devices installed on the ceiling board 16, the opening 161 of the ceiling board 16 has a relatively small diameter. For example, some LED downlights and heat detectors have an opening 161 having an aperture of about 60Φ. In the case of the opening 161 having such a small diameter, it is conceivable that the operator cannot insert his / her hand through the opening 161 and pull out the wiring W1. In such a case, additional work such as an operator entering the ceiling A1 and passing the wiring W1 through the opening 161 is required. Originally, the ceiling, which is a lightweight steel-framed ceiling base called light heaven, may not have sufficient strength assuming that a person can ride on the ceiling, which may cause difficulty in work. Then, a worker different from the worker who installs the equipment under the ceiling is required, and there is a problem that the artificial increase increases and the construction cost is pushed up.

Therefore, the inventor of the present application has devised a wiring fixture for temporarily fixing the end portion of the wiring W1 in the attic A1 near the opening 161. FIG. 4 is a perspective view for explaining the configuration of the wiring fixture installed behind the ceiling. Further, FIG. 5 is a vertical view of the configuration of the wiring fixture installed behind the ceiling. The wiring fixture 20 is attached before the ceiling board 16 is attached. The wiring fixture 20 includes a nominal wire 22 and a fixing structure 24.

The call line 22 is a number line wound so as to run between the pair of field edge receivers 12. The nominal wire 22 is wound so as to overlap the horizontal coordinates of the planned installation position 162 of the electric device (that is, to pass directly above the planned installation position 162). Here, the space between the pair of nearest field edge receivers 12 on both sides of the planned installation position 162 is wound in a direction parallel to the field edge 14 (that is, a direction orthogonal to the field edge receiver 12). ing.

The fixing structure 24 is for temporarily fixing the end portion of the wiring W1 to the nominal wire 22. The fixed structure 24 is, for example, a binding member that bundles the end portions of a plurality of wirings W1. Examples of such a binding member include insulating tape and a binding band. The fixing structure 24 fixes the end portion of the wiring W1 to the nominal wire 22 at a position directly above the planned installation position 162 of the electric device. Here, for example, a portion bound by the fixing structure 24 is temporarily fixed by sandwiching it between the nominal lines 22.

The fixed structure 24 may be, for example, a connector member attached to the end of the wiring W1. In this case, there are two or more wirings W1 that are actually connected even in the crossover wiring. For example, if the connector member is a plug-in connector called a wago, the surface material is removed from the sheath and peeled off, and then two wirings are provided at the end. The end portion of the wiring W1 may be temporarily fixed to the nominal wire 22 by passing the nominal wire 22 through a closed loop formed between the wiring W1 and the connector member.

The installation of the electrical equipment that can be seen under the ceiling is performed after the ceiling board 16 is attached. FIG. 6 is a cross-sectional view of the periphery of the opening after the ceiling board is attached, as viewed from the horizontal direction. As shown in this figure, according to the wiring fixture 20 described above, the end portion of the wiring W1 is fixed directly above the planned installation position 162. Therefore, the operator can easily pull out the wiring W1 to the indoor space A2 by opening the opening 161.

Further, according to the wiring fixture 20 of the present embodiment, the nominal wire 22 is wound so as to hang between the pair of field edge receivers 12. As illustrated in FIG. 5, the field edge 14 may be cut when the planned installation positions 162 overlap. On the other hand, since the field edge receiver 12 is a structural member that supports the field edge 14 and the ceiling board 16, it is not cut because the planned installation positions 162 overlap. Therefore, according to the wiring fixture 20 of the present embodiment, the nominal wire 22 can be reliably installed, so that the end portion of the wiring W1 can be stably and temporarily fixed directly above the planned installation position 162. It will be possible.

3. 3. Wiring fixing method using a wiring fixing tool Next, a wiring fixing method using a wiring fixing tool 20 will be described. Temporary fixing of the end portion of the wiring W1 by the wiring fixing method is performed before the ceiling board 16 is attached. In the wiring fixing method, a specific step, a winding step, and a fixing step are performed in order.

FIG. 7 is a diagram for explaining a specific process in a wiring fixing method using a wiring fixing tool. In the specific process, the planned installation position 162 of the electric device is specified. Here, in the indoor space A2, the electric equipment is installed before attaching the ceiling board 16 in which the field edge receiver 12 which is the ceiling base is suspended and the field edge 12 is fixed to the field edge receiver 14 with a clip or the like. The position P1 in the horizontal coordinate system is specified by issuing the ground ink at the planned position. Then, the planned installation position 162 is specified by marking the light sky base with a marking laser or the like from the specified position P1 vertically upward.

FIG. 8 is a diagram for explaining a winding process in a wiring fixing method using a wiring fixing tool. In the next winding step, the nominal wire 22 of the wiring fixture 20 is wound between the pair of field edge receivers 12 sandwiching the planned installation position 162 of the plurality of field edge receivers 12. At this time, the nominal wire 22 is wound so as to cross directly above the planned installation position 162 (that is, the horizontal position of the nominal wire 22 overlaps with the planned installation position 162). From the viewpoint of suppressing the slack and looseness of the nominal wire 22, it is preferable to wind it around the nearest field edge receivers 12 on both sides of the planned installation position 162. Further, by setting the winding direction to be orthogonal to the longitudinal direction of the field edge receiver 12, it is possible to suppress slack and looseness due to the positional deviation of the nominal wire 22.

FIG. 9 is a diagram for explaining a fixing process in a wiring fixing method using a wiring fixing tool. In the next fixing step, the end portion of the wiring W1 is fixed to the nominal wire 22 by using the fixing structure 24. At this time, the end portion of the wiring W1 is fixed at a position directly above the planned installation position 162. The fixed structure 24 is not limited. For example, when a binding member is used as the fixed structure 24, first, the end portions of the plurality of wirings W1 are bundled by the binding member. Then, the root portion of the bundle at the end of the plurality of wirings W1 formed by the binding member is hooked on the calling wire 22.

According to the wiring fixing method using such a wiring fixing tool 20, the end portion of the wiring W1 can be temporarily fixed directly above the planned installation position 162 before the ceiling board 16 is attached. As a result, the operator can easily pull out the wiring W1 to the interior space A2 by opening the opening 161 after attaching the ceiling board 16.

4. Modification Example The wiring fixture applied to the suspended ceiling structure of the present embodiment may adopt a modification as follows.

The winding structure of the nominal wire 22 in the wiring fixture 20 is not limited to the above. That is, as long as the winding structure of the nominal wire 22 is wound around at least a pair of field edge receivers 12 facing each other across the planned installation position 162, the winding method and structure thereof are not limited.

The fixing structure 24 in the wiring fixture 20 is not limited to the above. That is, the fixing structure 24 is not limited in its fixing method and structure as long as at least the end portion of the wiring W1 can be fixed directly above the planned installation position 162.
