  By the way, when a building is inundated on the floor due to flooding or the like, it is considered that water infiltrates into the interior space of the wall, so that the insulation in the wall is immersed in water and cannot be used. In that case, it may be necessary to replace the heat insulating material in the wall immersed in water with a new heat insulating material. Here, as described above, since the heat insulating material in the wall is a large member formed as a single piece over the entire height direction of the space in the wall, it may be difficult to handle the heat insulating material when replacing the heat insulating material in the wall. Conceivable. Therefore, there is a possibility that a great deal of labor may be required when exchanging the insulation material in the wall.

  In order to solve the above-mentioned problem, the wall heat insulating structure of the building of the first invention is a wall heat insulating structure of a building in which a wall heat insulating material is disposed in a wall space between two opposing wall surface materials, The in-wall heat insulating material is divided into a plurality of parts in the vertical direction in the inner space, and between each of the in-wall heat insulating materials adjacent to each other in the vertical direction, there is a separating member that separates the in-wall heat insulating materials from each other. It is provided.

  According to the present invention, a plurality of in-wall heat insulating materials are provided vertically divided in the inner space, and the in-wall heat insulating materials adjacent to each other in the vertical direction are separated by the members to avoid mutual contact. . For this reason, even if water enters the interior space due to floor flooding, etc., and some of the insulation inside the wall is immersed in water, water is sucked up by the insulation in the wall above the The damage can be prevented from spreading upward. And since the replacement work of the wall insulation material needs to be performed only for some of the wall insulation materials immersed in water among the plurality of wall insulation materials, the work load when replacing the wall insulation materials is reduced. be able to.

  Moreover, since it is only necessary to replace the heat insulating material in the wall wetted by water, the heat insulating material in the wall that is not wet can be used as it is. Therefore, the in-wall heat insulating material can be used without waste as compared with the conventional configuration in which the in-wall heat insulating material over the entire height direction of the in-wall space is replaced.

  Here, it is desirable that the separating member is formed in a long shape between two in-wall heat insulating materials adjacent in the vertical direction. If it does so, the effect which prevents more reliably the heat insulating material adjacent up and down can be anticipated. Further, if the separating members are further provided in the entire thickness direction of the in-wall heat insulating material, the contact between the in-wall heat insulating materials adjacent in the vertical direction can be more reliably prevented.

In addition, an inserted portion for inserting the water detection device is provided in a state of straddling a plurality of heat insulating materials in the wall.

  If a plurality of insulation materials in the wall are divided vertically in the interior space as described above, if the inundation situation in the interior space can be grasped, which wall insulation material is submerged, a new wall It is possible to determine how much internal heat insulating material should be prepared. In that respect, in the present invention, an insertion portion for inserting the water detection device is provided in the wall space, and the water detection device inserts the water detection device into the insertion portion so that the water detection device can check the inundation state of the wall space. It can be detected. In this case, it is convenient because the inundation state of the in-wall heat insulating material can be confirmed without removing the in-wall heat insulating material from the inner wall space. In addition, the water detector can be inserted into the wall space without being brought into contact with the heat insulating material in the wall by inserting the water detecting device into the inserted portion, so that the inundation status can be confirmed without damaging the heat insulating material in the wall.

Is provided with an opening serving as an insertion port of the water detection device into the groove.

  By the way, in the wall space, the wall heat insulating material may be provided in contact with the back surface of the wall surface material, for example, by disposing the wall heat insulating material in the entire thickness direction of the wall space. Accordingly, in the present invention, in view of this point, a groove portion for inserting the water detection device is formed on the contact surface of the wall surface material with the in-wall heat insulating material. Thereby, even if the heat insulating material in the wall is in contact with the back surface of the wall surface material in the space in the wall, it is possible to confirm the flooded state of the space in the wall by inserting the water detection device along the groove portion of the wall surface material. Moreover, since a water detection apparatus can be inserted in a groove part through the wall surface material which has a groove part, or the opening provided in the upper direction or the downward direction, the inundation condition of the space in a wall can be confirmed, without removing a wall surface material.

The inner wall finishing material is attached to the inner wall base material by attaching an attachment portion.

  In general, the inner wall finishing material is attached to the inner wall base material with an adhesive or the like. Therefore, when the inner wall finishing material is removed when replacing the inner heat insulating material, it is necessary to break the inner wall finishing material or the like. Therefore, it has been difficult to reuse the inner wall finishing material after the replacement of the inner wall insulating material. In that respect, in the present invention, since the inner wall finishing material is detachably attached to the inner wall base material, the inner wall finishing material can be removed without breaking the inner wall finishing material.

And a plurality of heat insulating materials 23 incorporated in the frame of the inner wall frame 22. The inner wall base material 21 is formed of, for example, a gypsum board. As shown in FIG. 3, a plurality of grooves 25 extending in the vertical direction are formed on the back surface of the inner wall base material 21 at predetermined intervals in the width direction of the inner wall base material 21. Specifically, each groove portion 25 is formed over the entire vertical direction of the inner wall base material 21.

  The inner wall frame 22 is configured by connecting a plurality of frame materials made of wooden squares. The inner wall frame 22 is formed to have substantially the same size (vertical and horizontal dimensions) as the inner wall base material 21 as a whole, and in the vertical direction (height direction) at both width direction end portions and intermediate portions of the inner wall base material 21. It has a vertical frame member 22a that extends and a horizontal frame member 22b that extends in the horizontal direction (the width direction of the inner wall substrate 21) at the lower end of the inner wall substrate 21. The inner wall frame 22 is not provided with a horizontal frame material at the upper end portion of the inner wall base material 21, and the frame inner region surrounded by the frame materials 22a and 22b is opened upward at the upper end portion of the panel. .

  The inner wall frame 22 further includes a partition frame member 22c that partitions the frame inner region in the vertical direction. A plurality of partition frame members 22c are stretched between adjacent vertical frame members 22a in the vertical direction at a predetermined interval, and are fixed to the vertical frame members 22a with screws or the like at both ends thereof. As a result, the inner region of the inner wall frame 22 is divided into a plurality of portions in the vertical direction by the partition frame material 22c, and each of the divided regions 31 is an installation space in which the heat insulating material 23 is installed. In the present embodiment, these divided regions 31 are formed with substantially the same size (vertical and horizontal dimensions).

  The frame members 22a to 22c of the inner wall frame 22 are formed to have substantially the same thickness dimension (length in the thickness direction of the inner wall panel 12).

  The heat insulating material 23 is configured by filling glass wool into a bag made of a polyethylene film having moisture resistance. The heat insulating material 23 is formed in a substantially rectangular parallelepiped shape as a whole. Specifically, the heat insulating material 23 has substantially the same size (vertical and horizontal dimensions) as the divided region 31 formed in the inner wall frame 22, and the partition frame material 22c. It is formed to have substantially the same thickness as the thickness dimension (length in the indoor / outdoor direction).

  The heat insulating material 23 is disposed in each divided region 31 of the inner wall frame 22 and is fixed to the inner wall frame 22 by a tucker or the like. In this case, the heat insulating materials 23 adjacent to each other in the vertical direction are separated from each other by the partition frame material 22c, and the heat insulating materials 23 adjacent to each other in the horizontal direction are separated from each other by the vertical frame material 22a. Thereby, the heat insulating materials 23 adjacent in the up-down direction and the heat insulating materials 23 adjacent in the left-right direction are in a non-contact state. In addition, each heat insulating material 23 is provided in a state where there is no gap between the inner surface of each of the frame members 22 a to 22 c in the divided region 31 and is in contact with the back surface of the inner wall base material 21. Therefore, in this installation state, the outdoor side surface of the heat insulating material 23 and the outdoor side surface of the inner wall frame 22 (frame materials 22a and 22c) are substantially flush with each other. Thereby, the heat insulating materials 23 adjacent to each other in the vertical direction are separated from each other by the partition frame material 22c in the entire thickness direction, and the heat insulating materials 23 adjacent to each other in the left and right direction are separated from each other by the vertical frame material 22a. .

  Returning to the description of FIG. 1, the inner wall panel 12 is fixed by attaching the inner wall frame 22 to the indoor side surface of the outer wall frame 15 of the outer wall panel 11 with a tapping screw or the like. In the installed state of the inner wall panel 12, an inner wall space 29 is formed between the outer wall material 14 and the inner wall base material 21, and the plurality of heat insulating materials 23 are arranged vertically in the inner wall space 29. And the heat insulating materials 23 adjacent up and down are separated by the partition frame material 22c. The heat insulating material 23 is installed on the indoor side of the outer wall frame 15 which is a structural member in the inner space 29. Therefore, in the building 10 of this embodiment, a so-called filling heat insulating method is adopted for the outer wall portion.

  An inner wall finishing material 28 forming an indoor surface is attached to the indoor side surface of the inner wall base material 21 of the inner wall panel 12 by adhesion or the like. The inner wall finishing material 28 is formed of, for example, a cloth (wallpaper).

  Below the inner wall panel 12, a floor surface material 35 that forms a floor surface is provided. The floor material 35 is made of particle board or the like, and is supported from below by a floor joist 34 installed on the upper surface of the floor beam 17.

  A baseboard 41 for covering the boundary portion is provided at a boundary portion between the lower end portion of the inner wall panel 12 and the floor material 35. The baseboard 41 is fixed to the indoor side surface of the inner wall base material 21 with an adhesive or the like. Specifically, the inner wall finishing material 28 is removed at the installation site of the baseboard 41 to expose the inner wall base material 21, and the baseboard 41 is fixed to the exposed portion.

  Above the inner wall panel 12, a ceiling surface material 37 forming a ceiling surface is provided. The ceiling surface material 37 is composed of, for example, a double-layered gypsum board and is supported by a field edge 36 attached to the lower surface of the ceiling beam 18.

  A peripheral edge 42 for covering the boundary portion is provided at the boundary portion between the upper end portion of the inner wall panel 12 and the ceiling member 37. Here, the structure of the peripheral edge 42 and its periphery will be described in detail. On the lower surface side of the ceiling surface material 37 above the inner wall panel 12 (specifically, the heat insulating material 23 installed at the uppermost stage), a base member 39 made of wooden square material is provided. The base member 39 is fixed to the field edge 36 with screws or the like via the ceiling surface material 37.

  An attachment member 43 to which the peripheral edge 42 is attached is fixed on the indoor side of the base member 39. The attachment member 43 is provided between the upper end portion of the inner wall base material 21 of the inner wall panel 12 and the ceiling surface member 38, and in this installed state, between the attachment member 43 and the upper end portion of the inner wall base material 21. A predetermined gap (hereinafter referred to as an opening 45) is provided. The opening 45 communicates with the groove 25 of the inner wall base material 21 and serves as an insertion port for inserting a water detection device 46 described later into the groove 25.

  A peripheral edge 42 is attached to the indoor side of the attachment member 43. The peripheral edge 42 is formed in an elongated shape along the upper end portion of the inner wall panel 12, and is made of, for example, a hard resin. The peripheral edge 42 is provided so as to straddle the indoor side surface of the mounting member 43 and the indoor surface of the inner wall finishing material 28, so that the opening 45 is covered by the peripheral edge 42. Further, the peripheral edge 42 is rotatable with respect to the attachment member 43, and is attached to the attachment member 43 through a hinge or the like, for example. In such a configuration, as indicated by a two-dot chain line in FIG. 1, the opening 45 is opened when the peripheral edge 42 is rotated indoors. That is, in the present embodiment, the opening 45 is opened and closed by the rotation of the peripheral edge 42.

  In addition, as a configuration for opening and closing the opening 45, other configurations (operation mechanisms) such as enabling the peripheral edge 42 to be slidable with respect to the mounting member 43 in addition to enabling the peripheral edge 42 to rotate are used. Also good. For example, as a configuration for opening and closing the opening 45 by sliding the surrounding edge 42, a guide rail that guides the surrounding edge 42 up and down is installed on the mounting member 43, and the surrounding edge 42 is moved up and down along the guide rail. Thus, a configuration for opening and closing the opening 45 is conceivable. Further, instead of making the entire surrounding edge 42 rotatable, only a part of the surrounding edge 42, for example, only the central portion in the longitudinal direction of the surrounding edge 42 may be made rotatable.

  Next, an operation procedure for replacing the heat insulating material 23 when the building 10 is flooded on the floor will be described with reference to FIG. FIG. 4 is a vertical cross-sectional view showing a state in which the flooding condition in the wall space 29 is confirmed.

  First, an operation for confirming the inundation state in the wall space 29 is performed. As shown in FIG. 4, the work is performed by rotating the peripheral edge 42 to the indoor side to open the opening 45, and the water detector 46 is inserted into the groove 25 of the inner wall base material 21 through the opened opening 45. Do by inserting. The water detector 46 includes a moisture detector 47, a harness 48 having one end connected to the moisture detector 47, and a device main body 49 that is connected to the other end of the harness 48 and displays the detection result of the moisture detector 47. It has. The moisture detector 47 detects the amount of moisture in the in-wall space 29. In the present embodiment, as the moisture detector 47, an electronic hygrometer that detects the humidity of the wall space 29 as the moisture amount is used. The harness 48 has at least the vertical length of the groove portion 25, and the water detector 47 and at least a part of the harness 48 are inserted into the groove portion 25 in the water detection device 46 at the time of checking for water immersion.

  The operation of inserting the water detection device 46 into the groove portion 25 is performed by inserting the water detection device 46 downward along the groove portion 25 of the inner wall base material 21 while the moisture detector 47 is hung from the lower end portion of the harness 48. Do. Then, the humidity of the in-wall space 29 detected by the moisture detector 47 is confirmed by the apparatus main body 49, thereby confirming the inundation status of the in-wall space 29 (and thus the heat insulating material 23). Here, when the lower heat insulating material 23 is submerged among the plurality of heat insulating materials 23 divided vertically by the water in the wall space 29, the area around the lower heat insulating material 23 that has been submerged is immersed in the wall space 29. It is conceivable that there is a difference between the humidity and the humidity around the upper heat insulating material 23 that is not submerged. Therefore, it is possible to confirm the infiltration of the heat insulating material 23 by detecting the humidity.

  It is not always necessary to use a humidity sensor as the water detection device 46 (moisture detector 47) in order to check the inundation status of the inner space 29, and other moisture detectors 47 may be used. For example, a water detection sensor that detects the presence or absence of water in the wall space 29 may be used as the moisture detector 47. In this case, the water detector 46 is inserted into the groove 25 under the condition that the wall space 29 is submerged, and the presence or absence of water in the wall space 29 is confirmed. In addition, as a water detection sensor, the thing of a structure provided with a pair of electrode and detecting the presence or absence of water based on the resistance value between each electrode, for example can be considered.

  The harness 48 of the water detection device 46 is provided with a plurality of marks (for example, scales) along the longitudinal direction. When the water detection device 46 is inserted into the groove portion 25, the water detector 47 is detected by the marks. The vertical position of can be confirmed. And in this work, while confirming the presence or absence of inundation in the inner space 29, if inundation is confirmed, it is also confirmed using the above-mentioned mark to what height the inundation space 29 has been submerged. . By checking the inundation height, it is possible to grasp which heat insulating material 23 has been immersed in water among the plurality of heat insulating materials 23 installed in the upper and lower walls 29, so a new heat insulating material 23 is prepared. Convenient to do.

  When water is confirmed in the wall space 29 by the above operation, the heat insulating material 23 is replaced. In this operation, first, the inner wall finishing material 28 and the inner wall base material 21 are removed from the building 10, and the heat insulating material 23 dipped in water is removed from the divided region 31 of the inner wall frame 22. Then, a new heat insulating material 23 is installed in the divided region 31. Thereafter, the inner wall base material 21 and the inner wall finishing material 28 are attached to the building 10, and a series of replacement work is completed.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  A heat insulating material 23 is provided in the wall space 29 between the opposing outer wall material 14 and the inner wall base material 21 by dividing the heat insulating material 23 into a plurality of portions in the vertical direction, and the heat insulating materials 23 are arranged between the heat insulating materials 23 adjacent to each other in the vertical direction. A partition frame member 22c separated in a non-contact state was provided. In this case, even when water enters the wall space 29 due to flooding on the floor or the like and a part of the heat insulating material 23 is immersed in water, the heat insulating material 23 above the water is sucked up, etc. Can be prevented from spreading upward. And since the replacement | exchange operation | work of the heat insulating material 23 should just be performed only about the one part heat insulating material 23 immersed in water among the some heat insulating materials 23, the work load at the time of replacing | exchanging the heat insulating material 23 can be reduced.

  Moreover, since it is only necessary to replace the heat insulating material 23 wetted by water immersion, the heat insulating material 23 which is not wet can be used as it is. Therefore, the heat insulating material 23 can be used without waste as compared with the conventional configuration in which the heat insulating material 23 over the entire height direction of the wall space 29 is replaced.

  Since the partition frame material 22c is formed in a long shape between the heat insulating materials 23 adjacent to each other in the vertical direction, an effect of more reliably preventing the heat insulating materials 23 adjacent in the vertical direction from being contacted with each other can be expected. Furthermore, since the partition frame material 22c is provided in the whole thickness direction of the heat insulating material 23, the contact between the heat insulating materials 23 adjacent to each other in the vertical direction can be more reliably prevented.

  A partition frame member 22c for connecting adjacent vertical frame members 22a to the inner wall frame 22 fixed to the back surface of the inner wall base material 21 was provided, and a member was constituted by the partition frame member 22c. In this case, the above-mentioned effect can be obtained while increasing the rigidity of the inner wall frame 22 by the partition frame material 22c.

  An insertion target portion (specifically, a groove portion 25) for inserting the water detection device 46 was provided in the inner wall space 29 in a state of straddling a plurality of heat insulating materials 23 extending in the vertical direction and arranged in the vertical direction. In this case, since the water detection device 46 can detect the inundation state of the wall space 29 by inserting the water detection device 46 into the insertion portion, the heat insulation material 23 can be removed without removing the heat insulation material 23 from the wall space 29. The inundation status can be confirmed. Moreover, since the water detection device 46 can be inserted into the inner wall space 29 without being brought into contact with the heat insulating material 23 by inserting the water detection device 46 into the inserted portion, it is possible to check the flooded state without damaging the heat insulating material 23. There are also advantages.

  In the wall space 29, the heat insulating material 23 was provided in contact with the back surface of the inner wall base material 21. And the groove part 25 extended up and down was formed in the contact surface with the heat insulating material 23 in the inner wall base material 21, and the opening part 45 used as the insertion port of the water detection apparatus 46 to the groove part 25 was provided above the inner wall base material 21. .
