However, in the case of the above-mentioned conventional mounting structure, when the wiring cable is routed to a falling portion such as a wall, a part of a heat insulating material laid on a field edge is cut out to perform wiring. Must. Therefore, electrical work must be performed at the same time as the construction work, and must be performed in accordance with the procedure of the construction work worker. Becomes

[0004] Further, since a part of the heat insulating material is cut off, there arises a disadvantage that the heat insulating property in the room is reduced.

[0005] Further, since the electric wiring unit, the wiring cable, and the wiring device (such as a transformer) are located above the heat insulating material laid on the field margin, the heat insulating effect cannot be obtained, and the heat is affected by the heat. The disadvantage is that the performance is impaired.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a mounting structure of an electric wiring unit having excellent heat insulation and workability.

[0007]

The mounting structure of an electric wiring unit of the present invention for solving the above-mentioned problems is substantially L in a plan view.
The electric wiring unit is arranged in the central portion of the mounting bracket formed in a V shape, and the locking hole of the electric wiring unit is locked to the locking piece extending from the mounting metal in this arrangement state. , The fitting portions formed on both ends of the mounting bracket are fitted to the respective field edges orthogonal to each other, and in this state, the electric wiring unit has the heat insulating material and the mounting bracket laid on the field edge. And the wiring cable extended from the electric wiring unit is positioned between the heat insulating material and the field edge.

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

FIG. 1 schematically shows the overall structure of the mounting structure of the electric wiring unit 1.

That is, the mounting structure of this electric wiring unit 1 is such that the electric wiring unit 1 is mounted on the field frame 3 via the mounting bracket 2.

The electric wiring unit 1 is formed in a substantially semi-cylindrical shape. A plurality of wiring cables 11 are extended in a bundle form from one end, and a hook-shaped locking hole 10 for suspending the electric wiring unit 1 is provided in the other end. There is.

The mounting member 2 is formed in a state in which a long plate member is bent into a substantially L shape in plan view. Further, a locking piece 21 is extended from the inside of the central bent portion, and the locking hole 21 of the electric wiring unit 1 is locked to the locking piece 21. Further, in this locked state, the central portion of the mounting metal member 2 has a sufficient area in which the electric wiring unit 1 can be arranged so that the electric wiring unit 1 arranged on the mounting metal member 2 is stable. It is made in shape. Further, both ends of the mounting bracket 2 are bent into an inverted concave shape that fits into the outer peripheral portion of the field frame 3 to form fitting portions 22.

The fittings 2 are attached by fitting the fitting portions 22 to the respective field frames 3 of the field frame 3 which are orthogonal to each other. At this time, since the fitting frame 22 is not fixed to the field frame 3 because the field frames 3 are fixed side by side, screws (not shown) that fix the adjacent field frames 3 to each other are used. After loosening to form a gap between the field frames 3, the fitting portion 22 is fitted to the field frame 3 and the screws (not shown) are retightened to fit them. In this way, with the mounting bracket 2 attached to the field frame 3, the corners of the field frame 3 are
It will be reinforced by the mounting bracket 2.

Then, the locking hole 21 of the electric wiring unit 1 is locked to the locking piece 21 of the mounting member 2, and the electric wiring unit 1 is placed on the mounting member 2. At this time, the heat insulating material 4 laid on the field frame 3 is locked while being pushed upward. Further, the wiring cable 11 extending in a bundle from the electric wiring unit 1 is passed through the field frame 3 so that the field frame 3 and the heat insulating material 4 are formed.
Since it will be sandwiched between and, there is no need to fix it. Therefore, the electric wiring unit 1 can be arranged and fixed on the mounting bracket 2 by a simple operation such as locking the locking hole 10 of the electric wiring unit 1 to the locking piece 21 of the mounting bracket 2, and the construction is easy. In addition to the length of the wiring cable 11, since the electric wiring unit 1 is located at the position of the field frame 3, it can be shortened.
It is possible to reduce the construction cost and the material cost of the wiring cable 11.

According to this mounting structure, the distribution cable 11
Since it is not necessary to cut out the heat insulating material 4 at the time of wiring, the construction can be easily performed without lowering the heat insulating property. In addition, since the electric wiring unit 1, the wiring cable 11 and the like are located below the heat insulating material 4, it is possible to prevent the performance of these things from being affected by thermal influences. Further, since the electric wiring unit 1 and the wiring cable 11 are all under the heat insulating material 4, the appearance in the completed construction state is improved.

Further, since it is not necessary to cut out the heat insulating material 4, it is not necessary to perform the wiring work of the electric wiring unit 1 in parallel with the work of laying the heat insulating material 4 and the like. You can concentrate and work on electrical work independently. Therefore, the number of work steps can be reduced, and work steps can be easily managed. In addition, since the construction work and the electric work can be performed independently, the inspection after each construction can be easily performed.

In this embodiment, the field frame 3
The mounting brackets 2 each having a substantially L-shape in plan view are used so as to be mounted at the corners orthogonal to each other. It may be a mounting bracket (not shown) in the form of a long straight plate having fitting portions 22 formed at both ends. However, in this case, in a state where the locking hole 10 of the electric wiring unit 1 is locked to the locking piece 21 of the mounting bracket (not shown), the electric wiring unit 1 is stable on the mounting bracket (not shown). It must be provided as a mounting bracket (not shown) having a sufficient width so that it can be placed at.

[0018]

As described above, according to the present invention, since the electric wiring unit is located below the heat insulating material laid on the ridge, the heat insulating material is cut off at the time of wiring. There is no need to pass a cable, and the construction can be performed easily, and a decrease in heat insulation can be prevented. In addition, the electric wiring unit can be placed and fixed on the mounting bracket by a simple work such as locking the locking hole to the locking piece of the mounting bracket. It can be easily removed. Further, since the electric wiring unit, the wiring cable, the wiring device, and the like are located below the heat insulating material, it is possible to prevent the performance from being deteriorated due to the thermal influence. Further, the inspection after the completion of the construction can be easily performed.

Further, since the wiring cable extended from the electric wiring unit is positioned between the heat insulating material and the field edge, it is not necessary to fix the wiring cable and the construction can be carried out efficiently. In addition, since the distribution cable can be routed from the position of the lower edge than the conventional hut beam or the second floor beam, it is possible to perform the distribution with the shorter distribution cable than before, and the reduction of the material cost related to the distribution cable, The construction work cost is reduced, and the appearance after the construction is improved.

Further, after the construction of the interior groundwork, the electric wiring unit is attached, and thereafter, the heat insulating material is laid and the work such as the wall ceiling can be performed separately. It is possible to perform electrical work independently and centrally, which reduces the number of work steps and facilitates management of work processes.

Further, the fitting of the electric wiring unit also plays a role of reinforcing the field edge.
