First, the locking construction method will be described. The locking construction method is a method of mounting a wall panel so as to be able to swing or displace with the swing of the skeleton. The wall panel is generally rectangular, and has a vertical stretch in which the longitudinal direction is arranged in parallel in the vertical direction and a horizontal stretch in which the wall panel is arranged in parallel in the horizontal direction. Hereinafter, a configuration in which the wall panel is vertically stretched and attached to the foundation and the beam will be described as an example.

With the longitudinal direction of the wall panel as the vertical direction, the Z-clip is attached to one of the upper and lower ends or the horizontal center near the ends. Meanwhile, the angles are attached to the foundation and the beam respectively. Then, by inserting the free end side of the angle into the gap between the Z clip attached to the wall panel and the wall panel, a plurality of wall panels are arranged on the foundation. The skeleton to which the angle is attached is appropriately selected depending on the place where the wall panel is arranged.

In the figure, 51 is the skeleton, 52 is the wall panel, and 53a and 53b are the skeleton. The attachment portion of the wall panel 52 to the 51, that is, the portion where the angle is inserted between the above-mentioned Z clip and the wall panel is shown. As shown in FIG. 7A, the plurality of wall panels 52 are attached to the skeleton 51 at both ends in the longitudinal direction. In this state, if the skeleton 51 behaves or deforms due to an earthquake or the like, the wall panel 52 may move in the in-plane direction with respect to the angle, that is, the skeleton 51, as described above in the mounting portions 53a and 53b. Therefore, as shown in FIG. 7B, the wall panel 52 follows the behavior / deformation of the skeleton 51, and the wall surface is prevented from being damaged or collapsed.

FIG. 7 shows a configuration in which the wall panel 52 is vertically stretched so that the longitudinal direction is vertical, but the horizontal configuration in which the longitudinal direction of the wall panel 52 is horizontal is 90 °. The same is true except that it is rotated.

Next, the heat insulating wall structure of the present embodiment will be specifically described.

Further, FIG. 2 is a cut end view in the width direction of the wall panel showing the manufacturing process of the heat insulating wall structure of FIG. In the present invention, as illustrated in FIG. 7, the wall panel has a rectangular plate-like main surface, and the width direction means the lateral direction.

As shown in FIG. 1A, in the heat insulating wall structure of the present invention, a wall material layer 10 composed of a plurality of wall panels 11 and a heat insulating layer 20 arranged on one surface side of the wall material layer 10 are provided. The heat insulating layer 20 has at least a plurality of heat insulating laminated bodies made of a plurality of heat insulating plates laminated in the thickness direction in the width direction of the wall panel 11. That is, the heat insulating layer 20 is formed by laminating a plurality of heat insulating plates in the thickness direction. Then, at least a part of the heat insulating laminate is adhered to the wall panel 11.

The wall panel 11 according to the present invention may be a plate-shaped member having a function as a base material for attaching a heat insulating plate, and a concrete molded plate or a cement molded plate is preferably used, and more specifically, hollow extrusion. Molded concrete panels, lightweight cellular concrete panels (ALC panels), precast concrete panels (PC panels), glass fiber reinforced cement panels (GRC panels), extruded cement plates (ECP) and the like are preferably used. The wall panel 11 illustrated in FIG. 1A is a hollow extruded concrete panel and has a hollow portion 11a along the longitudinal direction. Further, as the wall panel 11, a fireproof panel or a heat resistant panel generally used as a wall material is also preferably used.

Further, the heat insulating plate according to the present invention is preferably a plate material made of a synthetic resin foam, for example, a polystyrene-based foam, a polyethylene-based foam, a polypropylene-based foam, a polyurethane-based foam, a phenol resin-based foam, or the like. Can be used. Among them, polystyrene foam is preferable because it has low water absorption and excellent heat insulation, and it may be either a bead foam molded product or an extruded foam molded product. However, since it has excellent pressure resistance, the expanded foam molded product is used. preferable. In the extruded foam molded product, there is an upper limit to the thickness of the heat insulating plate that can be molded well, and the present invention is preferably applied in forming the heat insulating layer 20 having a thickness exceeding the upper limit.

FIG. 1 is an example in which two heat insulating panels are stacked in the thickness direction to form a heat insulating layer 20, and the first heat insulating laminated body 21 and the second heat insulating laminated body 22 are formed in the width direction of the wall panel 11. The heat insulating layer 20 is formed by arranging them alternately in the left-right direction of the paper surface). In the first heat insulating laminate 21, as shown in FIG. 1 (b), heat insulating plates 21a and 21b having different lengths in the width direction are integrated via an adhesive layer 31b, and the wall panel 11 side. The length L3 of the heat insulating plate 21a is longer than the length L4 of the heat insulating plate 21b on the side away from the wall panel 11, and both ends of the heat insulating plate 21a project from both ends of the heat insulating plate 21b. On the other hand, as shown in FIG. 1 (c), the second heat insulating laminated body 22 is composed of heat insulating plates 22a and 22b having different lengths in the cross section in the width direction, and is different from the first heat insulating laminated body 21. On the contrary, the length L6 of the heat insulating plate 22a on the wall panel 11 side is shorter than the length L7 of the heat insulating plate 22b on the side away from the wall panel 11. The sum of the length L3 of the heat insulating plate 21a and the length L6 of the heat insulating plate 22a, and the sum of the length L4 of the heat insulating plate 21b and the length L7 of the heat insulating plate 22b correspond to the length L2 of the wall panel 11, respectively. do.

As shown in FIG. 2, the first heat insulating laminate 21 is fixed to the wall panel 11 by adhering the heat insulating plate 21a to the wall panel 11 via the adhesive layer 31a. At this time, the heat insulating plate 21a is adhered only to one wall panel 11 so as not to be adhered over the two wall panels 11 and 11. Then, the second heat insulating laminate 22 is fitted in the gap between the adjacent first heat insulating laminated bodies 21 and 21. At this time, the second heat insulating laminate 22 is only fitted and is not adhered to the wall panel 11. Further, the boundary between the two adjacent first heat insulating laminates 21 and 21 is not adhered to at least one of them. In FIG. 1A, the second heat insulating laminate 22 shows a configuration in which it is not adhered to any of the two adjacent first heat insulating laminated bodies 21 and 21.

In the embodiment of FIG. 1, since each of the plurality of first heat insulating laminates 21 is adhesively fixed to only one wall panel 11 and is not adhered to the adjacent second heat insulating laminated body 22, the wall is formed. The first heat insulating laminate 21 slides and shifts from each other at the boundary between the first heat insulating laminate 21 and the second heat insulating laminate 22 with respect to the swing or displacement of the panel 11. Easily follow the swing or displacement of the wall panel 11 individually. Further, since the second heat insulating laminate 22 is not adhered to the first heat insulating laminated body 21 and the wall panel 11, even if the wall panel 11 swings or is displaced, the first heat insulating laminated body 21 and the wall are formed. At the boundary with the panel 11, the surface of the panel 11 slides and shifts, so that the stress received from the wall panel 11 and the first heat insulating laminate 21 can be relaxed.

Therefore, in the present embodiment, even if the wall panel 11 swings or is displaced due to the shaking of the skeleton due to an earthquake or the like, the damage of the heat insulating layer 20 is suppressed.

Further, in the present embodiment, at the boundary between the first heat insulating laminate 21 and the second heat insulating laminated body 22, each side surface has a step, and the boundary is formed in the cross section in the width direction of the wall panel 11. It is non-linear. Therefore, the movement of moisture and moisture from one space sandwiching the heat insulating wall structure of the present embodiment to the other space is suppressed.

As an application embodiment of the present embodiment, one of the two first heat insulating laminates 21 and 21 adjacent to the second heat insulating laminated body 22 in the width direction of the wall panel 11 is the first heat insulating laminated body 21. It may be adhered to the second heat insulating laminate 22.

Further, in the present embodiment, in the width direction of the wall panel 11, the boundary 11b of the two adjacent wall panels 11 and 11 is located in the heat insulating plate 22a on the wall panel 11 side of the second heat insulating laminated body 22. The boundary 11b may coincide with one side surface of the heat insulating plate 22a. However, in order to prevent the movement of moisture and moisture, it is preferable that the boundary 11b and both side surfaces of the heat insulating plate 22a are separated from each other, and the distance between the boundary 11b and both side surfaces of the heat insulating plate 22a is equal. , L1 = L6 / 2. The length L6 of the heat insulating plate 22a may be set within a range in which the effect of the present invention can be obtained, and is not particularly limited, but may be, for example, about 80 mm to 120 mm.

The length L8 of the end portion of the heat insulating plate 22b protruding from the end portion of the 22a is not particularly limited as long as it can form a step within a range that can prevent the movement of moisture and moisture, but is, for example, about 30 mm to 70 mm. good. Further, in order to follow the swing or displacement of the wall panel 11 of the first heat insulating laminate 21 and to reduce the bias of stress generated in the heat insulating layer 20 due to the swing or displacement, the end portion of the heat insulating plate 21b. It is preferable that the lengths of the ends of the more protruding heat insulating plate 21a are equal at both ends.

It is a cut end view of the heat insulating laminate used for the heat insulating wall structure. The present embodiment will be described only with respect to the parts different from the first embodiment described above.

The heat insulating laminate 23 used in the present embodiment is formed by adhering two heat insulating plates 23a and 23b having the same length L9 via an adhesive layer 31d, but both ends thereof are bonded to each other in the width direction of the wall panel 11. Adhere by shifting only L10. The length L9 of the heat insulating plates 23a and 23b corresponds to the length L2 of the wall panel 11, and the heat insulating laminating body 23 is formed by adhering the heat insulating plate 23a on the wall panel 11 side to the wall panel 11 via the adhesive layer 31a. Is fixed to the wall panel 11. At this time, in the width direction of the wall panel 11, each of the plurality of heat insulating laminates 23 is adhered to one wall panel 11, and one heat insulating laminate 23 is not adhered to the two wall panels 11 and 11. By doing so, the heat insulating laminate 23 easily follows the swing or displacement of the wall panel 11 and damage to the heat insulating layer 20 is prevented. Further, since the heat insulating laminate 23 has a step on the side surface and the boundary between the two adjacent heat insulating laminated bodies 23 is non-linear in the cross section in the width direction of the wall panel 11, one of them sandwiches the heat insulating wall structure. The movement of moisture and moisture from one space to the other is suppressed.

In the present embodiment, the distance L10 from the end of the heat insulating plate 23a to the end of the heat insulating plate 23b in the width direction of the wall panel 11 only needs to be able to form a step within a range that can prevent the movement of moisture and moisture, in particular. Although not limited, it may be, for example, about 30 mm to 70 mm.

Further, in the present embodiment, when the heat insulating laminate 23 is bonded to the wall panel 11, the end portion of the heat insulating plate 23a on the wall panel 11 side and two walls adjacent to each other in the width direction of the wall panel 11 are adjacent to each other. As shown in FIG. 3A, it is preferable that the boundaries 11b of the panels 11 and 11 coincide with each other from the viewpoint of ease of work.

From the viewpoint of preventing the movement of moisture and moisture, the end portion of the heat insulating plate 23a on the wall panel 11 side may be separated from the boundary 11b of the wall panels 11 and 11, but in that case, the heat insulating plate may be separated. It is necessary that the end portion of the heat insulating plate 23a projecting toward the adjacent wall panel 11 from the end portion of the wall panel 11 to which the 23a is adhered is not adhered to the adjacent wall panel 11.

4 (a) is a cut end view of the wall panel in the width direction schematically showing the configuration of a part of another preferred embodiment of the heat insulating wall structure of the present invention, and FIG. 4 (b) relates to the same. It is a cut end view of the heat insulating laminate used for the heat insulating wall structure. This embodiment will be described only with respect to the parts different from the above-described first and second embodiments.

The heat insulating laminate 24 used in the present embodiment is formed by adhering two heat insulating plates 24a and 24b of the same length L11 via an adhesive layer 31e, but one end portion in the width direction of the wall panel 11. A convex portion 24c is formed on the surface, and a concave portion 24d is formed on the other end portion. The convex portion 24c and the concave portion 24d are continuous in the longitudinal direction (direction orthogonal to the paper surface) of the wall panel 11, respectively. The height of the convex portion 24c (length in the width direction of the wall panel 11) L12 corresponds to the depth of the concave portion 24d (length in the width direction of the wall panel 11) L13, and the thickness T1 of the convex portion 24c is the concave portion. The distance of the opening of 24d (distance in the thickness direction of the heat insulating plates 24a and 24b) corresponds to T2, and the convex portion 24c fits into the concave portion 24d. The length L11 of the heat insulating plates 24a and 24b corresponds to the length L2 of the wall panel 11, and the heat insulating laminating body 24 is formed by adhering the heat insulating plate 24a on the wall panel 11 side to the wall panel 11 via the adhesive layer 31a. Is fixed to the wall panel 11. After the one heat insulating laminate 24 is adhered to the wall panel 11, the concave portion 24d or the convex portion 24c of the adjacent unbonded heat insulating laminated body 24 is fitted into the convex portion 24c or the concave portion 24d of the bonded heat insulating laminated body 24. While doing so, the heat insulating laminate 24 is adhered to the wall panel 11 adjacent to the wall panel 11 to which the bonded heat insulating laminate 24 is adhered. In the width direction of the wall panel 11, the plurality of insulation laminates 24 are each adhered to one wall panel 11 so that one insulation laminate 24 is not adhered over the two wall panels 11 and 11. As a result, the heat insulating laminate 24 easily follows the swing or displacement of the wall panel 11 and damage to the heat insulating layer 20 is prevented. Further, since the heat insulating laminate 24 has a step on the side surface due to the convex portion 24c or the concave portion 24d, the boundary between the two adjacent heat insulating laminated bodies 24 is non-linear in the cross section in the width direction of the wall panel 11. Moisture and moisture transfer from one space across the insulation wall structure to the other are suppressed.

In the present embodiment, the height L12 of the convex portion 24c and the depth L13 of the concave portion 24d, the thickness T1 of the convex portion 24c and the distance T2 of the opening of the concave portion 24d are within a range that can prevent the movement of moisture and moisture. It suffices if a step can be formed, and is not particularly limited. For example, L12 and L13 may be about 30 mm to 70 mm, and T1 and T2 may be about 30 mm to 70 mm.

Further, in the present embodiment, when the heat insulating laminate 24 is bonded to the wall panel 11, the end portion of the heat insulating plate 24a on the wall panel 11 side and two walls adjacent to each other in the width direction of the wall panel 11 are adjacent to each other. As shown in FIG. 4A, it is preferable that the boundaries 11b of the panels 11 and 11 coincide with each other from the viewpoint of ease of work.

From the viewpoint of preventing the movement of moisture and moisture, the end portion of the heat insulating plate 24a on the wall panel 11 side may be separated from the boundary 11b of the wall panels 11 and 11, but in that case, the heat insulating plate may be separated. It is necessary that the end portion of the heat insulating plate 24a projecting toward the adjacent wall panel 11 from the end portion of the wall panel 11 to which the 24a is adhered does not adhere to the adjacent wall panel 11.

Both the recesses 25c and 25d are continuous in the longitudinal direction (direction orthogonal to the paper surface) of the wall panel 11. The depth L15 of the recess 25c (the length in the width direction of the wall panel 11) L15 and the depth L16 of the recess 25d may be different from each other, but are preferably equal.

The heat insulating block 26 is made of the same material as the heat insulating plates 25a and 25b, and the length L17 and the thickness T5 in the width direction of the wall panel 11 are the length L15 + L16 and the thickness of the space formed by the recesses 25c and 25d. It corresponds to the distances T3 and T4 in the vertical direction.

The length L14 of the heat insulating plates 25a and 25b corresponds to the length L2 of the wall panel 11, and the heat insulating plate 25a on the wall panel 11 side is bonded to the wall panel 11 via the adhesive layer 31a to bond the heat insulating laminate 25. Is fixed to the wall panel 11. Then, when one heat insulating laminate 25 is bonded to the wall panel 11, one end of the heat insulating block 26 is fitted into the recess 25c or 25d of the bonded heat insulating laminate 25, and then the adjacent unbonded heat insulating laminate 25 is fitted. While fitting the other end of the heat insulating block 26 into the recess 25d or 25c of the above, the heat insulating laminate 25 is adhered to the wall panel 11 adjacent to the wall panel 11 to which the bonded heat insulating laminate 25 is adhered. .. That is, in the width direction of the wall panel 11, the plurality of heat insulating laminates 25 are each adhered to one wall panel 11, and one heat insulating laminate 25 is not adhered to the two wall panels 11 and 11. By doing so, the heat insulating laminate 25 easily follows the swing or displacement of the wall panel 11 and damage to the heat insulating layer 20 is prevented. Further, the heat insulating laminate 25 has a step on the side surface due to the recesses 25c and 25d and the heat insulating block 26, and the boundary between the two adjacent heat insulating laminated bodies 25 is non-linear in the cross section in the width direction of the wall panel 11. Therefore, the movement of moisture and moisture from one space sandwiching the heat insulating wall structure to the other space is suppressed.

In the present embodiment, the length L17 and the thickness T5 of the heat insulating block 26 are not particularly limited as long as they can form a step within a range that can prevent the movement of moisture and moisture, but may be, for example, about 30 mm to 70 mm. ..

Further, in the present embodiment, when the heat insulating laminate 25 is bonded to the wall panel 11, the end portion of the heat insulating plate 25a on the wall panel 11 side and two walls adjacent to each other in the width direction of the wall panel 11 are adjacent to each other. As shown in FIG. 5A, it is preferable that the boundaries 11b of the panels 11 and 11 coincide with each other from the viewpoint of ease of work.

From the viewpoint of preventing the movement of moisture and moisture, the end of the heat insulating plate 25a on the wall panel 11 side may be separated from the boundary 11b of the wall panels 11 and 11, but in that case, the heat insulating plate may be separated. It is necessary that the end portion of the heat insulating plate 25a projecting toward the adjacent wall panel 11 from the end portion of the wall panel 11 to which the 25a is adhered does not adhere to the adjacent wall panel 11.

In the third embodiment, the shape of the convex portion 24c at the end of the heat insulating laminate 24 is a semicircle shown in FIG. 6 (a), a triangle shown in FIG. 6 (b), and a trapezoid shown in FIG. 6 (c). May be good. Further, in the fourth embodiment, the shape of the heat insulating block 26 may be a circular shape shown in FIG. 6 (d), a diamond shape shown in FIG. 6 (e), or a concave portion as shown in FIG. 6 (f). 25c and 25d may be trapezoidal in shape.

Further, in the above-described embodiments 1 to 4, the heat insulating laminates 21 to 25 each show a two-layer structure in which two heat insulating plates are laminated, but in the present invention, the heat insulating laminated body has a structure in which three or more layers are laminated. There may be. In the case of three or more layers, in the first and second embodiments, the boundary between the adjacent heat insulating laminates may be stepped. Further, in the third embodiment, it is sufficient that there is at least one combination of the convex portion 24c and the concave portion 24d at the boundary between the adjacent heat insulating laminates, and in the case of three or more layers, the end portion of the intermediate heat insulating plate is shifted. Therefore, the convex portion 24c and the concave portion 24d can be provided. Further, in the fourth embodiment, at least one heat insulating block 26 may be fitted and arranged at the boundary of the adjacent heat insulating laminates, and the recesses 25c and 25d may be formed by shortening the length of the intermediate heat insulating plate. Can be provided.

In the heat insulating wall structure of the present invention, another member may be further laminated on the respective surfaces of the wall material layer 10 and the heat insulating layer 20, and for example, a moisture-proof material covering the boundary between two adjacent heat insulating plates is adhered. This is preferable because the movement of moisture and humidity through the boundary is suppressed.

In the above embodiments 1 to 4, the heat insulating layer 20 is provided only on one surface of the wall material layer 10, but in the present invention, the heat insulating layer 20 is provided on both surfaces of the wall material layer 10.
