Summary of the Invention
Problems to be Solved by the Invention
[0004] However, in the above - mentioned conventional technology, it is necessary to arrange the installed items in the ceiling space in order from those that should be located above. Therefore, electrical wiring cannot be installed unless ducts, pipes, air - conditioning and ventilation equipment, etc. have been installed first, and the construction procedure is limited, so the work efficiency may be poor. Also, even after construction, when replacing or repairing electrical wiring, it may be necessary to temporarily remove installed items such as ducts, pipes, air - conditioning and ventilation equipment, etc., and the work efficiency may be poor.
[0005] In view of the above points, an object of the present invention is to provide an in - ceiling wiring method and an in - ceiling wiring structure capable of improving work efficiency.

[0006] The present invention provides a method for wiring in a ceiling, comprising the steps of: installing a partition wall between a ceiling slab and a floor; installing a plurality of wiring support devices on the side surface of the partition wall; installing electrical wiring on the plurality of wiring support devices; and providing a ceiling support member connected to a plurality of suspension bolts suspended from the ceiling slab, wherein the plurality of wiring support devices are located above the ceiling support member.
[0007] The ceiling wiring structure of the present invention comprises a partition wall installed between a ceiling slab and a floor, a plurality of wiring support devices installed on the side of the partition wall, electrical wiring installed on the plurality of wiring support devices, and a ceiling support member provided in connection with a plurality of suspension bolts hanging down from the ceiling slab, wherein the plurality of wiring support devices are located above the ceiling support member.
[0008] According to the ceiling wiring method and ceiling wiring structure of the present invention, electrical wiring is installed on multiple wiring support devices installed on the side of a partition wall. As a result, this electrical wiring can be installed independently of other fixtures installed in the ceiling space, improving the neatness of the installation and allowing for greater flexibility in the order of the installation procedures, thereby improving work efficiency. Furthermore, even after installation, when replacing or repairing the electrical wiring, it is not necessary to remove other fixtures, further improving work efficiency. [Brief explanation of the drawing]
[0009] [Figure 1] A schematic side view showing a ceiling wiring structure according to an embodiment of the present invention. [Modes for carrying out the invention]
[0010] A ceiling wiring method according to an embodiment of the present invention will be described with reference to Figure 1. Note that Figure 1 is a schematic diagram illustrating this embodiment, and the dimensions are simplified.
[0011] First, a partition wall 30 is installed between the ceiling slab 10 and the floor 20. The ceiling slab 10 is also the floor slab of the upper floor. The floor 20 can be a floor slab or a double floor panel, etc. A partition wall 30 is installed between the bottom surface of the ceiling slab 10 and the top surface of the floor 20.
[0012] The partition wall 30 is installed on the floor surface of a building for purposes such as dividing rooms or creating corridors. Although not shown in detail, the partition wall 30 is formed, for example, by sandwiching both sides of a frame, which is formed by bridging a horizontal frame between a pair of vertical frame members, with a pair of panel materials such as lightweight aerated concrete panels (ALC panels), and fixing the pair of panel materials to the frame. The method of installation of the partition wall 30 is not particularly limited, and it may be fixedly installed on the ceiling slab 10 or floor 20, or it may be installed so as to be movable relative to them.
[0013] Next, the process of installing multiple wiring support devices 40 on the side of the partition wall 30 is carried out. The wiring support devices 40 can be anything that can support electrical wiring 41, such as hooks, wiring racks, or rails. In this case, the wiring support devices 40 are hooks that can support multiple electrical wires 41, and multiple hooks 40 are fixed to the side of the partition wall 30 at horizontal intervals using anchors 42 or bolts.
[0014] The hook 40 is made, for example, by bending a metal rod such as steel or aluminum into a U-shape and covering it with an insulating material such as rigid polyvinyl chloride. Here, the hook 40 is fixed to the partition wall 30 using an anchor 42. Alternatively, multiple hooks 40 or the like may be installed on the side of the partition wall 30, and wiring racks, rails, etc. (not shown) installed using these hooks 40 or the like may be provided as wiring supports.
[0015] Next, the process of installing electrical wiring 41 on multiple wiring support fixtures 40 is carried out. This electrical wiring 41 is part or all of the electrical wiring that was conventionally installed in the ceiling. Although not shown in the figures, it is preferable to install the multiple electrical wirings 41 on the wiring support fixtures 40 in a bundled state using cable ties or the like.
[0016] The same electrical wiring 41 may be installed across multiple partition walls 30 using hooks 40 or wiring racks or rails supported by hooks 40, etc. Although not shown in the figures, multiple wiring support devices 40 may also be installed on the same partition wall 30 at intervals in the vertical direction. The electrical wiring 41 installed on the wiring support devices 40 must be limited to an extent that does not affect the strength of the partition wall 30.
[0017] After or before this process, more preferably simultaneously and in parallel, a process is carried out to arrange electrical wiring other than the electrical wiring 41 installed on the partition wall 30 using wiring support devices 40, as well as various ducts 51, pipes 52, air conditioning and ventilation equipment (not shown), and other items 50 to be installed in the ceiling space. These items 50 can be installed in the same manner as in the conventional method, using anchors or the like to the ceiling slab 10, starting with those that should be located at the top. By carrying out these processes simultaneously and in parallel, it is possible to shorten the construction period.
[0018] Next, a ceiling support member 62 is installed, connected to a plurality of suspension bolts 61 suspended from the ceiling slab 10, thereby constructing the suspended ceiling structure 60.
[0019] Although details are not shown here, for example, first, several suspension bolts 61 are suspended from the ceiling slab 10. Then, suspension fittings (not shown) are installed on the lower ends of these suspension bolts 61, and joist hangers 63 are connected to these suspension fittings. Then, several joists 64 perpendicular to the joist hangers 63 are connected below the joist hangers 63 with clips (not shown). Furthermore, ceiling panels (ceiling finishing materials) 65 made of finishing boards or decorative boards are installed below the joists 64. However, the structure and construction method of the suspended ceiling structure 60 are not limited to this, and it is sufficient that there is a space between the ceiling slab 10 and the ceiling panels 65. Note that the suspension bolts 61 may be installed on the ceiling slab 10 before the installation of the fixtures 50.
[0020] The ceiling support member 62, consisting of joist hangers 63 and joists 64, is located below the wiring support 40 installed on the partition wall 30. As a result, the electrical wiring 41 that is installed on the wiring support 40 on the partition wall 30 is installed in the space above the ceiling between the ceiling slab 10 and the ceiling panel 65.
[0021] This completes the in-ceiling wiring structure according to an embodiment of the present invention. This in-ceiling wiring structure comprises a partition wall 30 installed between a ceiling slab 10 and a floor 20, a plurality of wiring support fixtures 40 installed on the side of the partition wall 30, electrical wiring 41 installed on the plurality of wiring support fixtures 40, and a ceiling support member 62 provided in connection with a plurality of suspension bolts 61 hanging down from the ceiling slab 10, wherein the plurality of wiring support fixtures 40 are located above the ceiling support member 62.
[0022] In the ceiling wiring method and the ceiling wiring structure according to the above-described embodiment of the present invention, the electrical wiring 41 is installed on a plurality of wiring supports 40 provided on the side surface of the partition wall 30. As a result, this electrical wiring 41 can be installed independently of other installations 50 arranged in the ceiling space, so that the arrangement is improved, and the order of the construction procedures for arranging them becomes flexible, making it possible to improve the work efficiency. Furthermore, since these processes can be carried out simultaneously in parallel, it is possible to shorten the construction period. Also, even after construction, when replacing or repairing the electrical wiring 41, it is not necessary to remove other installations 50 once, making it possible to improve the work efficiency.
[0023] Note that the present invention is not limited to the ceiling wiring method and the ceiling wiring structure specifically described in the above-described embodiment, and can be appropriately changed within the scope described in the claims.
[0024] For example, after arranging installations 50 such as various ducts, pipes, air conditioning and ventilation equipment, a partition wall 30 may be provided, wiring supports 40 may be installed on this partition wall 30, and the electrical wiring 41 may be installed.
