  By providing the through holes in the base frame as described above, it is possible to equip the partition wall with electrical wiring while utilizing the space in the wall. However, in the configuration in which the electrical wiring passes through the through hole of the base frame, air flows from the ceiling space or the like into the space in the wall through the through hole. Therefore, there is a concern about the decrease in the heating and cooling efficiency in the indoor space. For example, in the case where an electric device such as a distribution board or a socket is provided on the wall surface of the partition wall, it is conceivable that air leakage may occur through the hole of the wall material provided for attaching the electric device.

  This invention is made in view of the said situation, and it aims at implement | achieving the wall structure of a highly airtight building.

  Hereinafter, means, etc. effective for solving the above-mentioned problems will be described while showing actions, effects and the like as necessary.

The first invention is

A wall structure of a building in which an in-wall space is formed between the longitudinal bars and the horizontal bars,
The horizontal bar is provided with a hole penetrating in the vertical direction, and wiring from the outside of the wall panel can be inserted through the hole in the hole;
In the state in which the wiring is inserted into the hole, a closing member is provided which closes a gap in the hole.

  When the wiring is attached using the space in the wall in the wall panel, the wire is inserted through the hole provided in the cross rail of the wall panel, but from the outside in the space in the wall through the hole It is feared that the airtightness of the indoor space is reduced due to the inflow of air. In this point, in the above configuration, the gap in the hole is closed by the closing member in a state where the wire is inserted into the hole, so that air from the outside flows into the space in the wall through the hole. Is suppressed. As a result, a highly airtight building wall structure can be realized.

  A second aspect of the invention is characterized in that the closing member is an elastic member that can expand and contract, and the clearance is closed by providing the elastic member in the hole in a compressed state. .

  In the above configuration, the base frame is provided with a pair of auxiliary vertical bars between the pair of vertical bars, and the distribution board is fixed between the pair of auxiliary vertical bars with the side surface fixed. . In this case, the distribution board can be suitably fixed in a limited-size in-wall space. In addition, since the space between the pair of auxiliary vertical bars is a long hole, it is possible to insert a plurality of wires connected side by side to the distribution board in the side by side through the hole. Furthermore, in this state, the plurality of wires can be substantially uniformly surrounded by the closing member. As a result, even if a relatively large hole is formed in order to insert a plurality of wires, it is possible to preferably block the air flow through the hole.

  According to a fifth aspect of the present invention, in the hole portion, a sticking portion to which the closing member is stuck is provided on one side across the wire in the thickness direction of the wall panel, and the wall in the hole portion The closing member on one side across the wire in the thickness direction of the panel is affixed to the wall panel by the attaching section, and the closing member on the other side across the wire is affixed to the wall panel It is characterized by not being attached.

Also, on the other side in the wall thickness direction, with the wall surface material fixed on both sides of the base frame, the closing member may be pressed into the gap in the hole, and the closing member may be properly in the hole even if there is no sticking part Can be housed in In this case, a suitable configuration can be realized while taking into consideration the operation of attaching the closing member to the inside of the hole.

  In a sixth aspect of the invention, the wall panel is fixed at its lower end to the floor and fixed at its upper end to the ceiling, and the hole in the cross bar at the top of the wall panel And a hole on the ceiling side is formed in the ceiling material of the ceiling part so as to penetrate up and down the ceiling material and to be connected to the hole, and the cross rail and the ceiling surface are provided. The closing member is provided in a compressed state in each of the holes of the material.

  When wiring for a distribution board is introduced from the space behind the ceiling into the space within the wall, as described above, the closing member is accommodated in the holes respectively provided in the cross section of the ceiling panel and the wall panel. The closing member is provided so as to straddle the boundary between the ceiling panel and the wall panel. Therefore, it can suppress that ventilation leak arises via the boundary part of a ceiling panel material and a wall panel.

  A seventh aspect of the invention is the elastic sheet in which the closing member is elastically deformable, and the elastic sheet has a notch formed from the peripheral portion toward the central portion, and the upper surface or the lower surface of the cross rail The elastic sheet is attached, and the gap is closed in a state in which cut end portions extending along the cut are overlapped.

  By attaching an expandable / deformable closing member (elastic sheet) to the upper surface or the lower surface of the crosspiece, the gap of the hole is closed. In this case, in particular, since the cut end portions extending along the cut of the elastic sheet are overlapped and the gap is closed in that state, the elastic sheet is provided so as to surround the wiring inserted in the hole from the periphery. Thus, the gap in the hole can be properly closed. In addition, even if the wire is not inserted into the hole, the hole can be properly closed by overlapping the cut ends.

In addition, in FIG. 1, about the partition wall 10, the internal structure inside a wallpaper 26 and the internal structure inside a wall material 22 are partially shown in the broken view.

  As shown in FIGS. 1 and 2, a partition wall 10 is provided in a building such as a house, and a living space such as an adjacent room is partitioned by the partition wall 10. The partition wall 10 is configured by arranging a plurality of wall panels 11 side by side. The wall panel 11 is formed in a substantially rectangular plate shape, and has a height dimension substantially the same as the ceiling height of the indoor space. The lower end of the wall panel 11 is fixed to the floor 13 and the upper end is fixed to the ceiling 12.

  The wall panel 11 has a base frame 21 as a wall base and a pair of wall materials 22 provided on both sides of the base frame 21. The base frame 21 is formed in a rectangular frame shape as a whole. The base frame 21 includes a pair of vertical bars 23 provided apart from each other, and a plurality of horizontal bars 24 connecting the vertical bars 23. The vertical bars 23 extend in the vertical direction (vertical direction), and the horizontal bars 24 extend in the horizontal direction (horizontal direction). Each of the vertical bars 23 and the horizontal bars 24 is a frame material formed in a long shape with a material such as wood, has a substantially rectangular cross section, and is a solid which can be driven in with a fixing tool such as a screw. It is a member.

  Further, in each cross rail 24, a plurality of through holes 25 penetrating in the thickness direction (vertical direction) of the cross rail 24 are provided as holes, and the wiring W is provided to the space in the wall through the through holes 25. It is possible to pass through. The wires W include wires for information communication in addition to the wires for power. In the present embodiment, the wiring W is introduced from the ceiling back space to the space in the wall, and the through holes 25 are provided in the horizontal bars 24 except the lowermost portion of the plurality of horizontal bars 24. Note that one through hole 25 may be provided for each cross rail 24, and the plurality of wires W may be inserted through the through hole 25.

  The wall material 22 is formed in a substantially rectangular shape by a plate material such as a gypsum board, and is disposed on both sides of the base frame 21. A wallpaper 26 is attached to the front side surface of each wall material 22 so as to straddle the boundary of the adjacent wall material 22 (wall panel 11). The wallpaper 26 is a finishing material formed in a sheet shape by a paper material, a synthetic resin material, or the like, and corresponds to a surface material forming the surface of the indoor side wall surface of the partition wall 10. The wallpaper 26 is superimposed on the wall material 22 and is attached to the indoor side plate surface of the wall material 22 by an adhesive or the like.

  On the wall of the partition wall 10, a distribution board 31, a light switch 32, and an outlet 33 are provided as electric devices. Among them, the illumination switch 32 and the outlet 33 are provided in an opening (not shown) formed in the wall surface material 22, and the wiring W provided through the through hole 25 is connected to the illumination switch 32 and the outlet 33. There is. In addition, as an electric device provided on a wall surface, an interphone, an acoustic device (speaker), an HEMS operating device, etc. can be considered.

  Next, the structure regarding installation of the electricity distribution panel 31 is demonstrated. FIG. 3 is a front view showing the attached state of the wall panel 11 in the building, and in particular shows the structure of the wall panel 11A on which the distribution board 31 is provided. Moreover, FIG. 4 is an exploded perspective view of wall panel 11A in which the electricity distribution panel 31 is provided. In FIGS. 3 and 4, of the both wall members 22 of the wall panel 11A, the wall member 22 on the side on which the distribution board 31 is not provided is attached to the base frame 21, and the side on which the distribution board 31 is provided. The wall surface material 22 of has been removed.

  The wall panel 11A shown in FIGS. 3 and 4 differs from the configuration of the other wall panels 11 in that it has a support structure for supporting the distribution board 31 in addition to the plurality of horizontal bars 24 between the pair of vertical bars 23. Have. That is, inside the pair of vertical bars 23, a pair of auxiliary vertical bars 41 extending upward from the horizontal bar 24 at an intermediate position in the vertical direction of the panel is provided parallel to the vertical bars 23. The separation dimension between the pair of auxiliary vertical bars 41 is substantially the same as the horizontal width of the distribution board 31, and the distribution board 31 is arranged between the pair of auxiliary vertical bars 41.

  The upper end of the auxiliary vertical bar 41 is at the same position as the upper end of the vertical bar 23, and the pair of vertical bars 23 and the pair of auxiliary vertical bars 41 are connected to each other by the upper bars 42 and 43. Specifically, the pair of auxiliary vertical beams 41 are connected to each other by the upper beam 42 at the upper end thereof. Further, the vertical bars 23 and the auxiliary vertical bars 41 are connected to each other by the upper bars 43 at the upper end portions at both end sides of the wall panel 11 in the left-right direction. The upper rails 42 and 43 constitute the upper horizontal rails in the wall panel 11.

  Here, among the upper beams 42 and 43, the central upper beam 42 is provided in a direction (vertical direction) in which the plate surface extends in the vertical direction, and hence the dimension of the wall panel 11 in the thickness direction is the vertical beam 23 or It is smaller than the same size of the crosspiece 24. Therefore, when the wall member 22 is attached to the base frame 21, the hole 44 (see FIG. 5A) is formed at a position corresponding to the upper crosspiece 42 on the upper surface of the wall panel 11. Insertion of the wiring W into the inner space is possible. A hole 44 is formed between the pair of auxiliary vertical bars 41. The holes 44 are long holes extending in a direction along the upper bar 42 as a longitudinal direction, and a plurality of (for example, about 10 to 30) wires W can be passed through the holes 44.

  Further, horizontal bars 45 and 46 for supporting the distribution board are bridged between the pair of auxiliary vertical bars 41.

  The wall member 22 is provided with a rectangular opening 27 for attaching the distribution board 31 to the wall panel 11. The distribution board 31 is exposed to the side of the wall through the opening 27. The distribution board 31 is fixed to the auxiliary vertical bar 41 by striking a screw 34 from the inside of the distribution board 31 in a state of being disposed between the pair of auxiliary vertical bars 41. That is, the side surfaces of the distribution board 31 are fixed to the pair of auxiliary vertical bars 41. A plurality of connector portions 35 for connecting a plurality of wires W are provided side by side on the upper surface of the distribution board 31.

  Moreover, the ceiling part 12 has the ceiling cross beam 14 and the field edge 15 as a ceiling base material, and the ceiling surface material 16. The ceiling beam 14 is connected to a ceiling beam not shown. The ceiling surface material 16 is formed of, for example, a two-ply gypsum board, and is fixed to the ceiling girder 14 with a screw or the like via the field edge 15.

  The ceiling panel 16 is formed with a hole 17 penetrating vertically and communicating with the hole 44 provided in the upper portion of the frame of the wall panel 11. The hole 17 has a long hole shape like the hole 44 at the top of the frame, and the opening dimension is also substantially the same as the hole 44. The wiring W is introduced into the space in the wall from the space behind the ceiling through the holes 17 and 44 in the ceiling panel 16 and the wall panel 11, and is connected to the distribution board 31 in the space in the wall.

  By the way, in the configuration in which the wiring W is introduced into the space in the wall through the holes 17 and 44 in the ceiling panel 16 and the wall panel 11, the air holes 17 and 44 serve as a ventilation path, thereby making the indoor space airtight. Is concerned that Therefore, in the present embodiment, in the state where the wire W is inserted into each of the holes 17 and 44, a closing member is provided in the gap existing in each of the holes 17 and 44, and the inside of the holes 17 and 44 is provided by the closing member. I try to close the gap.

  FIG. 5 is a cross-sectional view showing the internal structure of the wall around the upper end portion of the wall panel 11, and more specifically, a cross-sectional view taken along the line A-A of FIG. (A) of FIG. 5 shows the state before inserting the wiring W and the closing member 51, and (b) shows the state after inserting the wiring W and the closing member 51. As shown in FIG. FIG. 6 is a cross-sectional view of the wall panel 11, specifically a cross-sectional view taken along the line B-B in FIG. 5 (b).

  As shown to Fig.5 (a), the hole 44 by the side of the wall panel 11 and the hole 17 by the side of the ceiling panel 16 are connected up and down. Thus, the space under the ceiling and the space in the wall above the ceiling material 16 are communicated with each other through the holes 17 and 44. In addition, it is good for the internal peripheral surface of the hole parts 17 and 44 to continue up and down as illustration.

  As shown in FIG. 5 (b) and FIG. 6, the closing member 51 is accommodated in the holes 17 and 44. The closing member 51 is an elastic member which is stretchable and deformable, for example, EPDM (ethylene propylene rubber) which is a foamed rubber material, and the hole 44 is formed on both sides of the wire W in the wall thickness direction (left and right direction in FIG. It is provided along the inner peripheral surface of. That is, the closing member 51 includes a first portion 51a disposed on one side of the wiring W in the wall thickness direction and a second portion 51b disposed on the other side. Each of the portions 51a and 51b has an elongated shape, and in a natural state, has a length that is larger than the size of the hole in the wall width direction. The closing member 51 is accommodated in the holes 17 and 44 in a compressed state. The closing member 51 is provided in the holes 17 and 44 in a state of straddling the boundary between the ceiling panel 16 and the wall panel 11.

  In FIG. 6, the plurality of wires W are arranged in a row without being stacked between the closing members 51. Thereby, the gaps in the holes 17 and 44 are less likely to occur than in the case where the plurality of wires W are stacked and arranged.

  The upper rail 42 is provided with a sticking portion 52 made of an adhesive or a double-sided tape on the side surface on the hole 44 side, and the first portion 51 a is stuck to the sticking portion. In this case, before the wire W is inserted into the hole 44, a part of the closing member 51 can be attached to the base frame 21 in advance.

  When the partition wall is manufactured by the wall panel 11A with a distribution board, the wall panel 11A is fixed at a predetermined partition position in a state where the wall material 22 is attached to one side of the base frame 21 (state of FIG. 4) Be done. At this time, the holes 17 of the ceiling panel 16 and the holes 44 of the wall panel 11A are aligned. Further, the distribution board 31 is fixed between the pair of auxiliary vertical bars 41 of the base frame 21.

  Thereafter, a plurality of wires W are introduced into the space in the wall through the holes 17 and 44, and the wire W is connected to the distribution board 31 in the space in the wall. In addition, before the wiring W is introduced into the space in the wall, the closing member 51 (here, particularly, the first portion 51 a) is pasted to the upper cross bar 42 of the base frame 21 by the pasting unit 52. Thereafter, the wall member 22 is attached to the side surface of the base frame 21 on the distribution board side. Then, for example, the second portion 51 b is pressed from the side of the ceiling space, whereby the gaps in the holes 17 and 44 are closed by the closing member 51. Here, in the hole portion 44, the closing member 51 on one side across the wire W in the wall thickness direction is attached to the base frame 21 by the attaching part 52, and the closing member 51 on the other side across the wire W Is not attached to the base frame 21.

  In addition, regarding attachment of the 2nd part 51b, the wiring in the hole parts 17 and 44 is carried out before the wall surface material 22 by the side of a distribution board is attached besides the structure which pushes in the 2nd part 51b from the side of a ceiling back space. The second portion 51b may be attached to the front side of W with a tape or the like, and in this state, the wall surface material 22 may be attached while the portions 51a and 51b are compressed and deformed.

  It is also possible to form the closure member 51 by integrating the first part 51a and the second part 51b (i.e. as a continuous integral long piece). Specifically, as shown in FIG. 7, about half of the closing member 51 is attached to the upper rail 42 as the first portion 51 a, and the remaining portion (non-attaching portion) is formed by the holes 17 and 44. After the wire W is inserted into the inside, the wire W is disposed on the near side so as to surround the wire W. Then, the wall material 22 is attached from the front side in a state in which the wiring W is surrounded by the closing member 51.

  Further, in the wall panel 11, it is preferable that a closing member is also provided in the through hole 25 which is the insertion portion of the wiring W for the light switch or the outlet. The configuration is shown in FIG.

  In the configuration shown in FIG. 8, an elastic sheet 53 is attached to the cross bar 24 of the base frame 21 as a closing member so as to close the through holes 25. The elastic sheet 53 is, for example, an expandable and deformable sheet material made of chloroprene rubber, and one surface thereof is a bonding surface to be bonded to the cross rail 24. The elastic sheet 53 is formed with a notch 54 from the peripheral portion toward the central portion, and in a state where the elastic sheet 53 is attached to the crosspiece 24, the cut ends extending along the notch 54 are overlapped. By combining them, ventilation through the through holes 25 is blocked (see the hatched portion in FIG. 8). Here, in the case where the wire W is inserted into the through hole 25, the wire W is surrounded by the elastic sheet 53, and the gap is closed by overlapping at the notch 54 (overlapping of the cut end portions).

  FIG. 9 shows a state in which the elastic sheet 53 is attached to the through hole 25 of the crosspiece 24 in the base frame 21. In FIG. 9, the illumination switch 32 is provided in the third wall space from the top among the upper and lower walls in the upper and lower five walls partitioned by the horizontal beam 24 and the fifth wall from the top (lowermost) The outlet 33 is provided in the space in the wall, and the wiring W is connected to the light switch 32 and the outlet 33. In this case, each through hole 25 of the crosspiece 24 is closed by the elastic sheet 53 above the illumination switch 32 on the upper side of the illumination switch 32 and the outlet 33. Thereby, even if the wall member 22 is provided with an opening for providing the light switch 32 and the outlet 33, the air permeability of the indoor space is prevented from being impaired through the opening.

  According to the configuration of the embodiment described above, the following excellent effects can be obtained.

  A structure in which the gap in the through hole 25 or the hole 44 is closed by the closing member 51 and the elastic sheet 53 in a state where the wire W is inserted into the through hole 25 or the hole 44 provided in the horizontal crosspiece 24 of the wall panel 11 And Therefore, it is suppressed that the air from the outside flows in to the space in a wall via the through-hole 25 or the hole 44. As a result, a highly airtight building wall structure can be realized.

  The closing member 51, which is an elastic member capable of expansion and contraction, is provided in the hole 44 in a compressed state, thereby closing the gap of the hole 44. In this case, the elasticity of the closing member 51 can be used to preferably close the gap around the wiring.

  In the configuration in which the distribution board 31 is attached to the wall panel 11A and the plurality of wires W are connected to the distribution board 31, the holes 44 are formed in a long hole shape, so that the plurality of wires W are formed. It can be suitably inserted into the portion 44. Then, the closing member 51 is provided along the inner circumferential surface of the hole 44 on both sides of the wire W in the wall thickness direction, so that the wires W are sandwiched from both sides in the wall thickness direction. In the state, the gap around the wiring can be suitably closed.

  In the base frame 21, a pair of auxiliary vertical bars 41 is provided between the pair of vertical bars 23, and the distribution board 31 is fixed between the pair of auxiliary vertical bars 41 with the side surface fixed. In this case, the distribution board 31 can be suitably fixed in a limited-size in-wall space. Further, since a long hole shaped hole portion 44 is formed between the pair of auxiliary vertical bars 41, the plurality of wires W connected to the distribution board 31 in the horizontal alignment are arranged in the hole portion 44 in the horizontal alignment state. A plurality of wires W can be substantially uniformly surrounded by the closing member 51 in this state. As a result, even if a relatively large hole 44 is formed in order to insert a plurality of wires W, air flow can be suitably blocked via the hole 44.

  In the wall structure in which the closing member 51 is interposed on both sides in the wall thickness direction with the plurality of wires W being inserted into the long hole-like hole 44, the closing member 51 (first portion 51a By placing the wiring W on the side (front side) of the closing member 51 without causing the falling of the closing member 51 (the first portion 51a) and the positional deviation. it can. Further, on the other side in the wall thickness direction, the closing member 55 (second portion 51b) may be pressed into the gap in the hole 44 in a state where the wall material 22 is fixed to both sides of the base frame 21 The closing member 51 can be properly accommodated in the hole 44 even if there is no space. In this case, a suitable configuration can be realized while taking into consideration the operation of attaching the closing member 51 to the inside of the hole 44.

  In the case where the wiring W for the distribution board 31 is introduced from the space under the ceiling into the space in the wall, as described above, in the holes 17 and 44 respectively provided in the cross panel 24 of the ceiling panel 16 and the wall panel 11A. Since the closing member 51 is accommodated, the closing member 51 is provided in a state of straddling the boundary between the ceiling panel 16 and the wall panel 11A. Therefore, it can suppress that ventilation leak arises via the boundary part of ceiling panel material 16 and wall panel 11A.

  By sticking the elastic sheet 53 on the upper surface of the crosspiece 24, the gap of the through hole 25 is closed. In this case, in particular, the cut end portions extending along the notches 54 of the elastic sheet 53 are overlapped and the gap is closed in that state, so that the wiring W inserted in the through hole 25 is surrounded from the periphery. 53 will be provided, and the clearance gap in the through-hole 25 can be closed appropriately. In addition, even if the wire W is not inserted into the through hole 25, the through hole 25 can be properly closed by overlapping the cut end portions.

  The present invention is not limited to the above embodiment, and may be implemented, for example, as follows.

  In the above embodiment, the upper end portions of the pair of auxiliary vertical bars 41 are connected by the upper bar 42, and the hole 44 is provided on the side (front side) of the upper bar 42, but even if this is changed For example, the upper rail 42 may be eliminated. In this case, a hole 44 is formed between the pair of auxiliary vertical beams 41, and the upper beams 43 separated from each other form the horizontal beams at the top of the wall panel 11.

  In the above embodiment, the wiring W is introduced from the ceiling back space to the space in the wall, but even if the wiring W is introduced from the space under the floor to the space in the wall by changing this. Good. In this case, it is preferable that a through hole or the like is provided in the lowermost horizontal bar of the base frame 21 and the through hole or the like be closed by the closing member.
