<Construction method>
Next, a wall surface construction method for constructing the outer wall 12 of the building 10 by arranging the heat insulation panel 100 and the sash 200 side by side in multiple stages vertically and horizontally will be described with reference to FIG. In addition, this construction method (construction method of an outer wall) is an example, Comprising: It is not limited to this. In addition, since the attachment structure of the heat insulation panel 100 and the sash 200 to the base steel frame 50 was already demonstrated, description is abbreviate | omitted here.

  As shown in order from FIG. 7 (A) to FIG. 7 (C), the heat insulating panels 100 are attached to the base steel frame 50 in order from the lower side in principle. Further, a sash 200 is attached to a portion that becomes an opening of the building 10. Further, the panel side stepped portion 122 of the heat insulating panel 100 arranged on the lower side or the sash side stepped portion 222 of the sash 200 arranged on the upper side of the panel side stepped portion 122 of the heat insulating panel 100 or the sash 200 provided on the lower side. It attaches so that the part 232 may cover (refer also FIG.2, FIG.3, FIG.5).

<Action and effect>
Next, functions and effects of the present embodiment will be described.

  A plurality of sashes 200 are attached to the base steel frame 50 to which a plurality of heat insulation panels 100 constituting the outer surface of the building 10 are attached. The sash 200 is configured such that the outer shape viewed in the out-of-plane direction is the same as or substantially the same as the outer shape of the heat insulating panel 100. Further, the joint shape of the heat insulating panel 100 and the outer shape of the sash 200 are substantially the same shape.

  And the sash side level | step-difference part 222 recessedly provided in the upper end part front surface of the sash 200 is covered by the panel side drooping piece part 132 which hangs down from the lower end front surface of the heat insulation panel 100 arrange | positioned upwards, The panel-side step portion 122 that is recessed in the front surface of the upper end portion of the heat insulating panel 100 in which the sash-side hanging piece 232 that hangs from the bottom is disposed is covered. Further, the portion where the sashes 200 are arranged side by side in the vertical direction is the sash side where the sash side stepped portion 222 recessed in the front surface of the upper end portion of the sash 200 hangs down from the front surface of the lower end portion of the sash 200. Covered by the hanging piece 232.

  Therefore, for example, the construction is easier than a configuration in which the base steel frame 50 to which the heat insulating panel 100 is attached is cut and a dedicated base steel frame for a sash is provided, and the sash is attached to the base steel frame for the sash. Furthermore, the sashes 200 are arranged in the vertical direction and can be easily attached to the base steel frame 50.

  Further, a metal worker (operator) who attaches the heat insulation panel 100 can attach the sash 200. Therefore, construction efficiency can be improved, construction period can be shortened, and construction management can be streamlined.

  Further, the sash side hanging piece 232 of the sash 200 is covered with the panel side stepped portion 122 of the heat insulating panel 100 arranged on the lower side or the sash side stepped portion 222 of the sash 200, and the sash side hanging piece 232 is the water return member. The water-stopping performance is ensured. Further, the gaps formed at the corners of the sash 200 are stopped by the water stop members 152 and 156. In particular, the main body 155 of the water stop member 156 is filled with the movement allowance E provided at the lower end 210T, and the hanging portion 157 is filled with a space between the sash side droop side 232 and the panel side step portion 122 to stop. Water.

  Even if water enters from the gap between the sash-side drooping piece 232 and the panel-side step 122 or the sash-side step 222, the water flows on both sides in the left-right direction and travels along both left-right ends of the sash 200. Fall down. Then, as indicated by an arrow M in FIG. 3, the dropped water droplet flows along the inclined surface 252 and is drained from the water drain notch 254. Therefore, for example, it is not necessary to separately provide a sash water returning member, a draining member, or the like. Moreover, this makes it possible to construct the outer wall 12 more flat.

  Here, by setting the thickness of the sash 200 to be the same as or substantially the same as that of the heat insulating panel 100, the sash 200 can be attached to the base steel frame 50 to which the heat insulating panel 100 is attached while the outer surface 12A is flush or substantially flush. It becomes. It should be noted that a configuration in which the sash 200 slightly protrudes is included, and conversely, a configuration in which the sash 200 is disposed slightly inside is also included. When the thickness of the sash is thicker than that of the heat insulating panel 100, the base steel frame 50 to which the heat insulating panel 100 is attached is cut and a dedicated base steel frame for the sash is provided inside, and the width of the base steel frame for the sash is widened. It is necessary to be flush with the outer surface of the heat insulation panel 100 by attaching a thick sash.

  Moreover, the structure (attachment change) of the sash 200 can be freely changed by adopting a structure in which the sash 200 is attached to the base steel frame 50 as described above and having the substantially same outer shape as the heat insulating panel 100. Therefore, the arrangement position of the sash 200 can be changed until just before the attachment, and the request of the builder can be easily met.

  Further, the movement allowance E provided on the lower side of the sash body 210 of the sash 200 shown in FIG. 3 and FIG. 5 is set to be larger than the gap necessary for attaching and detaching the sash 200 to and from the building 10 in the vertical direction. Thus, the sash 200 can be easily attached and detached by moving the sash 200 in the vertical direction after construction. Therefore, when it becomes necessary to change the position of the sash 200 after the construction, it can be easily changed as compared with a configuration in which the movement allowance E is not provided. In the present embodiment, the movement allowance E is filled with the main body 155 of the water stop member 156. Therefore, when the sash 200 is moved in the vertical direction, the water stop member 156 is removed by cutting or the like. Since the water stop member 156 is rubber or foam, it can be easily removed.

<Modification>
Next, a modification of the above embodiment will be described.

  In the above embodiment, the sash 200 is configured such that the outer shape viewed in the out-of-plane direction is the same shape or substantially the same shape as the outer shape of the heat insulating panel 100, but is not limited thereto. For example, the sash 201 whose length in the left-right direction is shorter than that of the heat insulation panel 100 may be used as in the modification shown in FIG. In this case, spacer members 101 as spacer panels or spacer sashes may be provided on the left and right sides of the sash 201 so as to have the same outer shape as the heat insulating panel 100.

<Others>
In addition, this invention is not limited to the said embodiment and modification.

  For example, in the above-described embodiment, the heat insulating panel 100 is attached to the base steel frame 50 in order from the lower side in principle, and the sash 200 is attached to the portion that becomes the opening of the building 10. However, it may not be attached in order from the lower side. For example, when the delivery of the sash 200 is not in time or when the type of the delivered sash 200 is changed, the heat insulating panel 100 above the sash 200 may be attached first. Further, in such a case, as in the above-described embodiment, if a movement allowance (interval) E is provided between the lower end 210T of the sash body 210 of the sash 200 and the upper end 100U of the heat insulating panel 100, it is easy. Since the sash 200 can be attached by post-construction, it is preferable.

  For example, in the said embodiment, although the sash 200 was attached to the base | substrate steel frame 50 to which the heat insulation panel 100 was attached via the L-shaped bracket 70 as an example of an attachment member, it is not limited to this. A configuration in which the sash 200 is directly attached to the base steel frame 50 may be employed. That is, the sash is attached to the longitudinal member directly or via an attachment member.

  For example, in the said embodiment, the sash 200 was attached only to the foundation | substrate steel frame 50 as an example of a vertical member. However, it is not limited to this. For example, you may attach to other members, such as the cross member 20 arrange | positioned at the back side of the foundation steel frame 50, via a fixing member. That is, the structure by which the sash was attached to both the vertical member and the other member may be sufficient. However, as in the above embodiment, the sash is preferably attached to only the vertical member. And it becomes easy to construct by setting it as the structure which attaches a sash only to a vertical member like the said embodiment, and construction time is shortened significantly.

  Further, for example, in the above-described embodiment, the base steel frame 50 as an example of the vertical member is fixed to the frame 14 such as the foundation 14, the slab, or the beam of the building 10 with an interval in the left-right direction. However, it may be a building structure in which the vertical members also serve as part of the housing.

  For example, in the said embodiment, although the panel side hanging piece part 132 was provided in the rear surface of the heat insulation panel 100, it is not limited to this. For example, the structure by which the panel side drooping piece part is not provided in the heat insulation panel may be sufficient. For example, in the said embodiment, although the heat insulation panel 100 was used as an example of an outer wall panel, it is not limited to this. For example, a steel plate panel or an ALC plate may be used.

  Further, for example, in the above-described embodiment, the sash 200 has been described using a sash of multi-layer glass as an example, but is not limited thereto. For example, a sash of single plate glass or three-layer glass may be used.

  Further, for example, in the above embodiment, the sash 200 is a fixed window (a fitting window, a FIX window), but is not limited thereto. For example, it may be a window with a protruding (smoke exhaust / ventilation) mechanism, or it can be ventilated while blindfolded by attaching and fixing a blind vane (bar). It may be a louver (vent). In the case of the louver, the sash frame (main body) is configured to be flush with or substantially flush with the outer wall panel. In other words, even if the blind blades (crosspieces) protrude outside the outer wall panel, if the sash frame (main body) is flush with or substantially flush with the outer wall panel, it is flush or flush. The

  Moreover, although the said embodiment demonstrated in the example which applied this invention to the outer wall structure of a building, it is not limited to this. The present invention can also be applied to an inner wall structure of a building. That is, the present invention can also be applied to a sash that forms the inner surface of a building (a wall surface inside the building) together with the inner wall panel, an inner wall structure that forms the inner surface of the building by the inner wall panel and the sash, and a method for constructing the inner wall. For example, the outer surface and the outer wall in the above embodiment are structured as the inner surface and the inner wall.

  Furthermore, it cannot be overemphasized that it can implement with a various aspect in the range which does not deviate from the summary of this invention.
