Description

[Technical Field]

[0001] The present invention relates to the floor structure of the first floor of a log house constructed using the log frame construction method. [Background technology]

[0002] In homes, many residents install wired devices such as electrical appliances that are connected to power and signal cables on desks or storage furniture that are placed against a wall, so indoor outlets to which power cables and other devices are connected are generally installed on the wall as wall-mounted outlets.

[0003] In the case of log houses, which are built using log construction methods, installing a wall outlet indoors requires wiring inside the structural log walls, but in this case, it is necessary to manufacture logs with wiring holes drilled in advance at a factory or the like, and then assemble them at the construction site to construct the log walls (see, for example, Patent Document 1). In this structure, it is nearly impossible to move or add wall outlets after the log walls are constructed unless the wiring is exposed.

[0004] Floor outlets, which are installed on the floor, can be relocated or added even after the log wall is constructed. However, floor outlets require the cords of electrical appliances and other devices to crawl along the floor, creating a problem of obstructing indoor walking. To prevent cords from obstructing walking, methods exist for freely positioning outlets using a double-floor structure (so-called free-access floors) (see, for example, Patent Document 2), but the double-floor structure reduces ceiling height and increases construction costs. Particularly in the case of log houses, which are constructed using log framing, adopting a double-floor structure and ensuring ceiling height would require an increase in the number of log layers used to construct the log wall, making this unacceptable in terms of construction costs.

[0010] The floor structure of the first floor of the log house of the embodiment will be described below with reference to the drawings. (Embodiments of the present invention)

[0011] FIG. 1 is a perspective view showing the floor structure of the first floor of a log house according to an embodiment of the present invention. FIG. 2 is a plan view with a lid partially cut away showing the state in which a power cord 9 for an electrical appliance is connected in the embodiment of the present invention. FIG. 3 is a front cross-sectional view showing the floor structure of the first floor of a log house according to an embodiment of the present invention. In this embodiment, the floor 2 on which the floor outlet box 1 is installed is the first floor floor 201, and the wall 7 is a log wall constructed using a log frame construction method. For convenience, the internal structure of the wall 7, which is a log wall in this embodiment, is omitted in FIGS. 1, 2, and 3, and only a portion above the first floor floor 201 is shown in FIGS. 1 and 3.

[0012] 1, 2, and 3, the structure according to this embodiment includes a floor outlet box 1 including an outlet 13 to which a power cord 9 of an electrical appliance is connected, a box 11 having a rectangular shape in plan view that houses the outlet 13, and a removable lid 12 that is installed to cover the entire top of the box 11. The box 11 is installed in plan view against a log wall of the first floor 201 built using log construction techniques on the first floor 201 of the room, so that its top surface is approximately flush with the top surface of the first floor 201. The box 11 is a rectangular parallelepiped having a plate-shaped bottom surface that is rectangular in plan view and a plate-shaped outer periphery that stands on the periphery of the bottom surface, and the entire top surface is open. While the shape of the box 11 in plan view is rectangular in this embodiment, it does not necessarily have to be rectangular as long as the shape is rectangular in plan view; it may be square or rectangular, approximately square. 1, 2 and 3, the entire top surface of the box body 11 is open, but in this embodiment the entire top surface does not necessarily have to be open, and as long as there is no interference with inserting the plug 91 into the outlet 13 attached inside the box body 11 described below and removing the power cord 9 of the electrical appliance connected to the outlet 13 into the room, the opening on the top surface of the box body 11 need not be the entire top surface, but may be almost the entire top surface except for a portion of the top surface.

[0013] As shown in Figure 2, at the installation position of the floor outlet box 1, a rectangular opening is provided on the edge of the first floor 201 (i.e., near the wall) that is approximately the same as the planar external shape of the floor outlet box 1, and a box body 11 is installed in the opening provided on the edge of the first floor 201, and a lid body 12 is placed on top of the box body 11 so as to cover the entire top of the box body 11, and the height of the top surface of the lid body 12 is approximately the same as the height of the top surface of the first floor 201.

[0014] As shown in Figure 3, the first floor 201 is built on horizontal joists 23 whose end faces are vertically long rectangles, and is composed of subfloor plywood 22, which is a horizontal structural surface material, and floor finishing materials 21, such as flooring materials, laid on top of the subfloor plywood 22.

[0015] As shown in Figure 3, the wall 7 erected on the edge of the first floor 201 is constructed on a base 5 placed horizontally on a foundation 6. In this embodiment, the wall 7 is an exterior wall, but it does not necessarily have to be an exterior wall as long as it is a log wall constructed using the log frame construction method, and it may also be an interior partition wall.

[0016] As shown in FIG. 3 , box body 11, which is an elongated rectangle in plan view, has one long side of its outer periphery, corresponding to its long side in plan view, attached to the indoor-side elevation of base 5, and the other long side attached to the elevation of support member 4 provided directly below first floor 201. This support member 4 also serves as one of joists 23, as shown in FIGS. 1 and 3 . That is, both long sides of box body 11 in plan view are sandwiched between base 5 and support member 4, which also serves as one of joists 23. As described above, in this embodiment, the shape of box body 11 in plan view may be a square or a rectangle that is approximately close to a square, as long as it is rectangular. When the shape in plan view is a square or a rectangle that is approximately close to a square, one side of its outer periphery in plan view is attached to the indoor side of base 5, and the other side, parallel to the one side, is attached to the elevation of support member 4 provided directly below first floor 201. In this embodiment, the support material 4 has been described as also serving as the joists 23, but the form of the support material 4 is not limited to this. For example, the present invention is applicable to a case where the support material 4 does not also serve as the joists 23 but is provided separately from the joists 23 directly below the floor 2, or a structure in which the joists 23 are not required by increasing the horizontal rigidity of the floor 2 (a so-called rigid floor structure). Note that in this embodiment, the box body 11 may be attached to the base 5 via edge joists 231 or spacers depending on the structure of the first floor floor 201. In this case, the box body 11 is also sandwiched between the base 5 and the support material 4 (however, the box body 11 is sandwiched between the base 5 and the support material 4 at two opposing sides of the outer periphery in a plan view (however, the base 5 is sandwiched via the edge joists 231 or spacers).

[0017] When forming a heat insulating layer on the first floor 201, heat insulating material (not shown) is installed in contact with the underside of the underfloor plywood 22 so as to fill the entire lower area of the first floor 201. In this case, the heat insulating layer is installed without gaps on the underside and outer peripheral surface of the floor outlet box 1 so as not to leave any missing parts even at the position of the floor outlet box 1.

[0018] Figure 4 is a right side cross-sectional view showing the state in which the power cord 9 of an electrical appliance has been removed in an embodiment of the present invention. For convenience, in Figure 4, the internal structure of wall 7, which is a log wall, is omitted and only a portion above the first floor 201 is shown. As shown in Figure 4, a wiring 14 is connected to outlet 13, and is drawn from the underfloor space outside floor outlet box 1 into the interior of floor outlet box 1, i.e., into box body 11. In addition to a power cord, wiring 14 may also be a LAN cable, an optical communication cable, a television antenna cable, a telephone line cable, etc. It is desirable to pull the wiring 14 into the interior of the box body 11 by providing a wire hole (not shown) on one of the two outer surfaces of the box body 11, excluding the two surfaces that contact the base 5 and joists 23, and introducing the wiring in a straight line through the insulation.In this way, when the horizontal length of the mounting surface of the outlet 13 inside the box body 11 is longer than the longitudinal length of the outlet 13, the wiring 14 can easily expand and contract inside the box body 11, and it becomes possible to arbitrarily select a suitable position on the mounting surface of the outlet 13 inside the box body 11 and mount the outlet 13.

[0019] As shown in Figure 2, outlet 13 is attached to the interior of box 11 on one of the interior elevations of box 11 that is parallel to and far from wall 7. By attaching outlet 13 in this position, power cord 9 of an electrical appliance connected to outlet 13 can be easily taken out of floor outlet box 1 from a position close to wall 7, i.e., into the room in which floor outlet box 1 is installed.

[0020] As shown in FIG. 4 , the outlet 13 has multiple connection ports 131 arranged in a horizontal row for connecting plugs 91 of the power cord 9 of an electrical appliance. In FIG. 4 , four connection ports 131 are shown for power plugs. While the present embodiment describes a case in which the power cord 9 of an electrical appliance, which is a cable, is connected via the plug 91 as an example of what is connected to the outlet 13, the cable is not limited thereto. For example, the present invention can be applied to connecting cables for wired devices in general, including signal cables other than power cords, such as LAN cables, optical communication cables, television antenna cables, and telephone line cables, via plugs. In other words, the outlet 13 is merely one example of a "connectable part" in the present invention, and the "connectable part" also includes the above-mentioned sockets for connecting signal cables, etc. The connection ports 131 are positioned vertically when the outlet 13 is attached to the interior elevation of the box 11, as shown in FIG. 3 . This prevents dust from entering the connection ports 131 when the plug 91 is not connected. Furthermore, since the insertion direction of the plug 91 is horizontal when connected to the connection port 131, the internal height dimension of the box 11 can be small.

[0021] 2 and 4, the size of box 11 is preferably such that the horizontal dimension of the mounting surface of outlet 13 inside is greater than the longitudinal dimension of the outer dimensions of outlet 13, and more preferably the horizontal dimension of the mounting surface of outlet 13 is at least twice the longitudinal dimension of the outer dimensions of outlet 13. This makes it possible to freely select the mounting position of outlet 13 inside box 11 within the mounting surface of outlet 13 inside box 11.

[0022] When the horizontal dimension of the mounting surface of the outlet 13 inside the box 11 is larger than the longitudinal dimension of the outer dimensions of the outlet 13, it is preferable that the attachment of the outlet 13 to the vertical surface inside the box 11 be detachable. Therefore, it is preferable that the attachment surface of the outlet 13 to the box 11 has a magnet (not shown). As shown in FIG. 4 , an iron plate 8 is attached to the vertical surface inside the box 11 to which the outlet 13 is attached, and as described above, a magnet (not shown) is attached to the attachment surface of the outlet 13 to the box 11. To attach the outlet 13 to the vertical surface inside the box 11 using a magnet, instead of the iron plate 8 in FIG. 4 , a commercially available magnetic paint that attracts a magnet may be applied to the vertical surface, or a commercially available magnetic sheet may be attached to the vertical surface. Alternatively, a hook-and-loop fastener or a suction cup may be used instead of a magnet to enable the outlet 13 to be detachably attached to the vertical surface inside the box 11.

[0023] As shown in Figure 4, the length of iron plate 8 is preferably greater than the longitudinal length of outlet 13 and is approximately equal to the overall longitudinal length of the interior of box 11. Iron plate 8 may be continuous with a gap in the middle inside box 11. This allows outlet 13 to be attached at any suitable position on the attachment surface of outlet 13 inside box 11. Note that in order to allow outlet 13 to be attached at any suitable position on the attachment surface of outlet 13 in this way, a hook-and-loop fastener or a suction cup may be used instead of the magnet as described above.

[0024] As shown in FIG. 2 , a lid 12 is placed on top of the box 11 so as to cover the entire opening at the top of the box 11. In FIG. 2 , the outer shape of the box 12 is a rectangular plate in a plan view, which is substantially the same as the shape of the box 11 in a plan view. The lid 12 has a wiring cutout 121 on one of its long sides in a plan view, through which the power cord 9 of an electrical appliance can be passed. The lid 12 is typically placed on the box 11 in use so that the wiring cutout 121 is located close to the wall 7. The number of wiring cutouts 121 may be one or more per lid 12. As described above, in this embodiment, the shape of the box 11 in a plan view may be a square or a rectangle that is approximately a square, so long as it is rectangular. Therefore, when the shape of the box 11 in a plan view is square, the position of the wiring cutout 121 in the lid 12 may be on any of the outer peripheral sides of the lid 12.

[0025] As shown in FIG. 2, when the box body 11 has a rectangular shape in plan view and the surface of the box body 11 that is attached to the indoor-side elevation of the base 5 is one of the long sides of the box body 11 in plan view, it is preferable that the lid body 12 is divided into lid body 12a that has a wiring cutout 121 and lid body 12b that does not have the wiring cutout 121 for one box body 11. In this way, the position where the power cord 9 of the electrical appliance exits the floor outlet box 1 can be changed at any time by interchanging the lid body 12a and the lid body 12b. Furthermore, the division of the lid body 12 into lid body 12a and lid body 12b may be such that either one or both of the lid body 12a and the lid body 12b are multiple. With this configuration, there are more options for changing the position where the power cord 9 of the electrical appliance exits the floor outlet box 1. [Industrial Applicability]

[0026] Because the present invention is configured in this way, it is possible to provide a floor structure for the first floor with a floor outlet box in a log house built using the log construction method, which ensures ceiling height while preventing cords connected to it from interfering with walking inside the room and not restricting furniture placement, thereby maintaining the aesthetic appearance of the room.In the case of log houses built using the log construction method, it has traditionally been nearly impossible to relocate or add wall outlets installed in the log walls, but by replacing the wall outlets previously installed in the log walls with the floor outlet box of the present invention, it is now possible to change the outlet position when changing the design or rearranging the log walls after construction.
