Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a wiring method for electrical equipment in a building, and more particularly to a wiring method for electrical equipment in a building that is suitable for the dry type 1 method.

(Prior art) For example, in conventional electrical wiring, a conduit pipe is bound to the reinforcing steel that makes up the wall with wire, and an outlet box is attached to the end of the conduit with the lid attachment part exposed on the surface. There is.

For this reason, equipment such as conduit pipes, outlets, switches, etc. must be placed in the formwork to avoid reinforcing bars prior to concrete pouring, and must be installed between reinforcing bars and formwork assembly. During interior construction, a joint frame was applied to the surface of the outlet box, and when a finishing board was installed on the wall, this board was also provided with an opening that faced the outlet box.

The current situation is that these methods are almost universally adopted because they are preferable and effective from the viewpoint of not exposing the equipment, that is, from the point of view of appearance. Previously, this had to be done in between reinforcing reinforcement, formwork assembly, etc., and the latter had to be done in between the erection of studs, prior to the installation of base and finishing boards, etc.

(Problem to be Solved by the Invention) Therefore, with the above-mentioned conventional means, the construction can be completed within a short period of time, taking advantage of the gaps between reinforcing reinforcement, formwork assembly, stud assembly, etc., and the time required to secure openings for finishing materials. etc., it is difficult to select the timing of construction, and there is almost no flexibility, so there is a drawback that sudden construction is often forced, and electrical wiring once installed,
It was almost impossible to change the location or add more equipment.

By the way, there are a wide variety of electrical appliances used in buildings these days, including lighting, air conditioners, and electricity.

In order to install a large number of electronic office equipment, a large number of outlets and switches are required, and the location of these devices and devices is often changed beyond the original plan, making it necessary to add and change wiring and equipment. However, conventional wiring methods have the disadvantage that they can hardly meet this need.

Further, when a new partition or the like is installed, there is no suitable method for newly installing wiring in accordance with the installation of such a partition.

In view of the above circumstances, the purpose of the present invention is to make it easy to select the timing of construction, to change the position of wiring and appliances, and to add them, while basically simplifying embedded wiring with a single main component. It is an object of the present invention to provide a wiring method for electrical equipment that can be applied to electrical equipment, is inexpensive, and has good workability.

(Means for Solving the Problems) In order to achieve the above object, the wiring method for electrical equipment of the present invention differs from the conventional method of embedding appliances such as conduit pipes, outlets, and switches inside concrete walls or boards. Completely different from conventional methods, this retrofitting method does not have any negative impact on the frame construction or base material assembly work, and has good consistency with the underfloor wiring.It is possible to install horizontal grooves, which correspond to wiring ducts, on the surface of the wall panel in advance. A vertical groove is provided, and then the wall panels are built so that the liquid grooves of the wall panels are adjacent to each other and communicate with each other, the ceiling wiring and the underfloor wiring are taken in the vertical groove, and the wiring is installed in the horizontal groove. Along with guiding in the horizontal direction,
After wiring, install an outlet box in the vertical and horizontal grooves.
When an outlet or the like is installed, a lid with an opening through which an outlet plate or a blind plate can be attached is fitted in a corresponding position. Alternatively, in order to simplify the structure of the wall panel, a horizontal groove corresponding to a wiring duct is provided on the surface of the wall panel in advance, and then a tube corresponding to a wiring duct having a thickness flush with the finished surface of the wall panel is formed. A line gutter is prepared, and when the wall panel is installed, the line gutter is placed adjacent to the panel at an arbitrary interval, and has an opening that communicates with the attic, under the floor, and the horizontal groove of the panel. Vertical wiring is carried out in the line gutter, such as by taking ceiling wiring and underfloor wiring into the line gutter, and horizontal wiring is carried out in the horizontal groove of the wall panel. When installing an outlet box, outlet, etc. inside the gutter,
A lid with an opening into which an outlet plate or blind plate can be attached is fitted in corresponding locations.

(Function) Finished wall panels, partition wall panels, steel partitions, and other wall panels have grooves that correspond to wiring ducts, so the vertical grooves are used to route V cables under the ceiling or under the floor. etc., directly into the vertical groove,
Depending on the intended wiring direction, it is possible to pass the wire through a horizontal groove and then through another vertical groove and return it to the floor or ceiling, or to install an outlet in the groove of the wall panel and wire it there. .

Finally, cover the groove in the wall panel, making it similar to concealed wiring.

Here, as for the surface of the wall panel, if both the front and back surfaces become walls by partitioning the indoor space, both the front and back surfaces will be the surface of the wall panel, so there will be horizontal grooves and vertical grooves on both surfaces. A groove will be provided.

Of course, it is also possible to install a cable conversion box in the groove of the wall panel and convert and connect the cables drawn in from the attic cable rack placed in the ceiling to flat cables for underfloor wiring.

Considering the strength of the wall panel and the use of reinforcing members, it is desirable to have fewer vertical and horizontal grooves in the wall panel. A line gutter that communicates with the floor is installed separately, simplifying the structure of the wall panels.

This line gutter may be made to have a certain degree of strength and may be used as a support for a wall panel if it is a partition.

In this way, in addition to ceiling wiring and underfloor wiring, wall panels are used as wiring areas, giving freedom and flexibility in the construction period and timing of electrical equipment, and making it easy to hide various changes in the existing building. This can be done with wiring.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a wall panel 1 of a partition wall. The upper and lower ends of the wall panel 1 are in contact with the ceiling 2 and the floor panel 3.

A vertical groove 4 is bored in the center of each wall panel 1, and a horizontal groove 5 that intersects with the vertical groove 4 is provided at a slightly lower position.
has been established.

However, in the embodiment, only one sheet does not have the vertical grooves 4.

In this way, not all of the grooves need to have vertical grooves 4 and horizontal grooves 5.

An outlet box is fixed to the lower part of the vertical groove 4, and an outlet 6 is attached to this.

At the beginning of the figure, the horizontal grooves 5 of each wall panel 1 are horizontally adjacent to each other and lined up in a straight line, and the wiring behind the ceiling 2, under-floor wiring, under-carpet wiring, etc. 4, and guide the wiring to another position using the horizontal groove 5.

When connecting a power line under the ceiling to the outlet 6, wire it as it is inside the vertical groove 4.

Finally, each transverse groove 5. A lid 7 is fitted into the vertical groove 4.

As shown in FIG. 1(B), the lid 7 has an engaging protrusion 8 on the back surface, and this protrusion 8 is pressed into contact with the inner surfaces of the grooves 4 and 5 so as to spread across them, and is fixed in the groove 4.5.

Further, an opening 9 is provided at an arbitrary position of the lid 7, and an outlet plate of the outlet 6 can be attached to the opening 9.

Therefore, a screw hole or the like is pre-drilled inside the vertical groove 4 so that the outlet box can be attached at a certain height position, and an opening 9 is also pre-drilled in the lid 7 to match this position. It is also possible to prepare one with a hole drilled in it and attach a mechanical plate when not in use.

The embodiment shown in Fig. 2 uses a wall panel 1a with only horizontal grooves 5, and wiring storage corresponding to a wiring duct is placed at a horizontally adjacent position of the wall panel 1a at an interval between two wall panels la, la. A line gutter 11 is provided for use.

A switch 12 is attached to the horizontal groove 5 of one of the wall panels 1a, and the wire gutter 11 and the horizontal groove 5 are connected so that the switch 12 is inserted in series between the wiring on the ceiling 2 and the wiring on the floor panel 3 side. is used for wiring.

(Effects) As explained above in detail, the wiring method for electrical equipment of the present invention provides vertical and horizontal grooves corresponding to wiring ducts in the wall panel itself, and connects the wiring with wiring devices in the ceiling and under the floor. Therefore, compared to the floor surface which is restricted by the open surface due to installed objects, the wall surface has a wide open surface, which not only provides flexibility in the construction period but also facilitates post-construction to accommodate changes in existing equipment or repositioning. There is an effect that can be done.

Furthermore, since a lid with an opening into which an outlet plate or a mechanical plate can be attached is fitted into the valley groove, the wiring is concealed, which has the advantage of being aesthetically pleasing.
