  However, after several years have passed since the composite panel was constructed in the building, the heat insulating material may deteriorate, or the outer outer wall molded plate may be damaged, causing deterioration in heat insulating performance, In some cases, the designability of the glass was lowered. For this reason, it is desired to replace the damaged / deteriorated outer wall molded plate or the heat insulating material with another new one. However, in the case of the conventional composite panel, it is very difficult to perform such replacement. This is because in the conventional composite panel, the heat insulating material is directly affixed to the outer wall forming plate or the inner wall forming plate, and its adhesiveness is strong, and it takes time to remove. Moreover, even if the heat insulating material or the outer wall molded plate can be removed, it is very difficult to attach a new heat insulating material or the outer wall molded plate again.

Moreover, in order to improve fire resistance, you may provide the refractory material formed with a calcium silicate, a calcium carbonate, a calcium sulfate etc. with the heat insulating material 3. FIG.

  Moreover, the filler 33 may be provided in the both ends of the heat insulation panel 1 over the full length of the composite panel A for the heat insulation reinforcement of the defect | deletion part of the heat insulation material 3. FIG. Similarly, fillers 33 may be provided on the upper and lower ends of the heat insulating material 3 over the entire length in the width direction of the composite panel A. In addition, the manufacturing method of the heat insulation panel 1 is not specifically limited, It can manufacture by a well-known method.

  As shown in FIG. 1, the heat insulation panel 1 may be one in which a pair of heat insulation panel segments 1 s and 1 s are connected in the horizontal direction. In this case, as shown in FIGS. 3 (a) and 3 (b), the fitting part S1 is fitted to one end of one heat insulation panel split 1s, and the one end of the other heat insulation panel split 1s is fitted. A joining portion S2 is formed, and both are fitted to form one heat insulating panel 1. Of course, the heat insulation panel 1 is not fitted, and may consist of one piece.

  As shown in FIG. 3 (a), the fitting portion S1 in one heat insulation panel split 1s is a flat surface in which one end portion of the surface metal plate 11 is bent and protrudes outward in order from the surface side. A substantially U-shaped covering portion 23, a concave curved portion 25, and a convex portion covering piece 26 protruding outward are formed. Further, one end portion of the back metal plate 12 is bent to form a stepped portion 30 and a convex portion 31 protruding outward from the back surface side in order.

  Moreover, as shown in FIG.3 (b), as for the to-be-fitted part S2 in the other heat insulation panel division | segmentation 1s, one edge part of the surface metal plate 11 is bending-processed, and the bending part 40 is sequentially carried out from the surface side. A front folded portion 42 and a support portion 45 projecting outward are formed. And the recessed part 41 is provided in the surface side of the front folding | turning part 42 so that the back surface metal plate 12 may be opposed over the full length of the front folding | turning part 42. FIG. Further, one end portion of the back metal plate 12 is bent, and a back folded portion 44 and a support portion 45 are formed in order from the back surface side. In this fitted part S2, a plate-shaped waterproof member 28 is provided on the support parts 45, 45 so as to bridge them. The bent portion 40 and the support portion 45 are formed substantially perpendicular to the surface metal plate 11.

  As shown in FIG. 3C, the fitting portion formed by the fitting portion S1 and the fitted portion S2 includes a covering portion tip 23a, a concave bent portion 25, and a stepped portion 30, respectively, a bent portion 40 and a front folded portion. The front end 42a and the rear folded portion front end 44a are opposed to each other, and the convex portion covering piece front end 26a and the convex portion front end 31a are in contact with the waterproof member 28. Further, the covering portion 23 is disposed so as to cover the dent portion 41. A gap 47 a is formed between the covering portion 23 and the bent portion 40, and a gap 47 b is formed between the step portion 30 and the rear folded portion 44. The gap 47a becomes a vertical joint 48 formed over the entire length of the surface of the heat insulating panel 1 in the vertical direction (see FIG. 1B).

  In the recessed portion 41, the fixture 9 is inserted in the direction of the heat insulating material 3 and penetrates the back surface metal plate 12 of the heat insulating panel split 1s, and is attached to the coupler 10 embedded in the precast concrete plate 2 described later. It is concluded. By fastening the fixture 9 and the coupler 10, the connection between the heat insulating panel 1 and the precast concrete plate 2 becomes more stable.

  Further, a flat screw 50 is inserted from the back side of the rear folded portion 44, and the rear folded portion 44 and the convex portion 31 are penetrated by the flat screw 50. With such a configuration, the fitted state between the heat insulating panel segments 1s becomes more stable.

  Next, the precast concrete board 2 will be described. The precast concrete plate 2 is provided so as to overlap with the surface of the back surface metal plate 12 of the heat insulating panel 1 and is formed in a flat plate shape or a block shape. The thickness of this precast concrete board 2 can be set suitably, for example, can be 100-300 mm.

No particular limitation is imposed on the concrete material forming the precast concrete plate 2, for example, it is a such as plain concrete design strength 36N / mm ^2. In addition, it is preferable that the inside of the precast concrete board 2 is formed by embedding a skeleton such as a reinforcing bar for the purpose of supplementing the strength.

  The shape and dimensions of the composite panel A of the present invention are not particularly limited. For example, if the composite panel A is formed in a vertically long rectangular shape, the composite panel A is vertically bonded. In this case, the height of the composite panel A is 1000 mm to 10,000 mm, The width can be 1000 mm to 3400 mm.

  In the composite panel A of the present invention, the heat insulating panel 1 and the precast concrete plate 2 are fastened by a fixture 9 provided on the heat insulating panel 1 and a coupler 10 embedded in the precast concrete plate 2. Are linked together.

  The fixing tool 9 is provided so as to penetrate from the surface of the surface metal plate 11 in the thickness direction of the heat insulating panel 1, and, for example, as shown in FIG. In the vicinity of the portion, a plurality can be provided with a predetermined interval over the entire length in the vertical direction. On the other hand, the coupler 10 is embedded in the precast concrete plate 2 and is provided at a position corresponding to the fixture 9 when the heat insulating panel 1 and the precast concrete plate 2 are overlapped. That is, when the heat insulation panel 1 and the precast concrete plate 2 are overlapped, the coupler 10 is embedded in the precast concrete plate 2 at a position where it can be fastened to the fixture 9. The location and the number of the fixing tool 9 and the coupling tool 10 are not particularly limited.

  For example, an insert nut can be used as the fixing bolt 9 and, for example, an insert nut can be used as the coupling tool 10. In this case, both are fastened by screwing.

  Further, as shown in FIG. 2, a spacer 13 such as a disk-shaped washer and a nut 14 may be interposed between the fixture 9 and the coupler 10. In this case, both the spacer 13 and the nut 14 are located in the precast concrete plate 2. Further, the nut 14 is fastened to the fixture 9, and a plurality of spacers 13 are interposed therebetween.

  As described above, since the heat insulating panel 1 and the precast concrete plate 2 are fastened and connected by the fixture 9 and the coupler 10, for example, when the heat insulating panel 1 is damaged, only the heat insulating panel 1 is used. Can be removed from the precast concrete plate 2. Moreover, it becomes possible to attach the new heat insulation panel 1 to the precast concrete board 2 as needed.

  For example, if it is the composite panel A shown in FIG. 1, the insulation panel 1 can be removed and attached according to the following procedures. First, all the fixtures 9 fitted to the adjacent heat insulating panel segments 1s and 1s, that is, the fixtures 9 inserted into the recessed portions 41 in FIG. 3C are removed. In this case, the covering portion 23 covering the fixture 9 may be turned up. When the spacer 13 and the nut 14 are provided between the fixture 9 and the coupler 10, the precast concrete plate 2 and the shaft of the fixture 9 are not in contact with each other, so that the fixture 9 can be easily removed. .

  Next, if the fixtures 9 inserted in the vicinity of both end portions of the heat insulation panel 1 in FIG. 1 are removed in order, the connection between the heat insulation panel 1 and the precast concrete plate 2 is released, and the heat insulation panel 1 becomes the precast concrete plate 2. Removed from.

  After the heat insulation panel 1 is removed, a new heat insulation panel 1 is attached by the following procedure. That is, the heat insulation panel 1 having the same size as the vertical and horizontal dimensions of the precast concrete plate 2 can be prepared and attached to the precast concrete plate 2. In this case, if the fixture 9 is inserted from the surface of the heat insulation panel 1 into a place facing the position of the coupler 10 embedded in the precast concrete plate 2 by measuring the dimensions in advance, the heat insulation panel 1 And the precast concrete plate 2 can be easily aligned, and the fixture 9 and the coupler 10 can be easily fastened. Moreover, when attaching the new heat insulation panel 1, you may attach what the pair of heat insulation panel division | segmentation 1s and 1s like the heat insulation panel 1 attached initially were fitted, and one heat insulation panel After the split 1s is connected to the precast concrete plate 2 by the fixture 9, the other heat insulating panel split 1s may be connected in the same manner. In addition, manufacture of the heat insulation panel 1 formed by fitting a pair of heat insulation panel division | segmentation 1s and 1s is mentioned later.

  In particular, when a new heat insulation panel 1 is attached to the precast concrete board 2, as shown in FIGS. 4 and 5, the heat insulation panel 1 and the precast concrete board 2 can be connected by an anchor member 90 such as a concrete jack. preferable. Here, FIG. 4 is a cross-sectional view of the vicinity of the end portion of the composite panel A after the heat insulating panel 1 is replaced with a new one, and FIG. 5 is a cross-sectional view of the fitting portion.

  When the new heat insulation panel 1 is attached to the precast concrete plate 2 by the anchor member 90, the anchor member 90 may be inserted directly from the surface of the new heat insulation panel 1. Specifically, after removing the heat insulation panel 1 originally attached to the composite panel A in the same procedure as described above, the new heat insulation panel 1 is stacked on the precast concrete plate 2 and then anchored from the surface of the heat insulation panel 1 The heat insulation panel 1 can be newly installed by inserting the member 90. Other procedures are the same as described above.

  The anchor member 90 has an anchor portion 92 serving as a shaft portion, an anchor portion distal end 91 at the distal end portion of the anchor portion 92, and an anchor member top portion 93 at the end opposite to the anchor portion distal end 91. The anchor portion tip 91 is formed like a drill blade. Therefore, the anchor member 90 serves not only as an anchor but also as a drill. As such an anchor member 90, the above-mentioned concrete jack is mentioned, for example.

  Since the anchor member 90 has the above-described structure, there is no need to provide a through-hole for inserting the anchor member 90 in the heat insulation panel 1 in advance, and when the heat insulation panel 1 and the precast concrete plate 2 are connected, from the surface of the heat insulation panel 1. The anchor member 90 can be directly inserted. When inserting the anchor member 90 into the heat insulating panel 1, a commercially available power tool or the like can be used. That is, by setting and operating the electric tool on the distal end portion (anchor member top portion 93) of the anchor member 90, the anchor member 90 is driven while penetrating the heat insulating panel 1 and the precast concrete plate 2 in this order. As shown in FIGS. 4 and 5, the anchor member 90 that has been placed has a part of the anchor portion 92 and a tip end 91 of the anchor portion disposed in the precast concrete plate 2, and a part of the anchor portion 92 is placed in the heat insulating panel 1. It arrange | positions and the anchor member top part 93 is arrange | positioned on the heat insulation panel 1 surface (or on the recessed part 41 surface).

  About the insertion location to the heat insulation panel 1 surface of the anchor member 90 and the insertion location to the dent 41 of the heat insulation panel division | segmentation 1s, 1s fitting part, it was embed | buried under the precast concrete board 2 when the anchor member 90 was inserted. The position is not particularly limited as long as it does not collide with or come into contact with the coupler 10. That is, as shown in FIGS. 4 and 5, when the anchor member 90 is inserted, the anchor member 90 is placed at a position where the anchor member 90 located in the precast concrete plate 2 and the coupler 10 do not contact each other. Insert it. In addition, what is necessary is just to investigate beforehand the position which does not contact the coupling tool 10 by measuring a dimension.

  Thus, if the anchor member 90 is used, the new installation operation of the heat insulation panel 1 can be performed more easily for the following reasons. That is, in the new installation of the heat insulation panel 1, in the method in which the fixture 9 is inserted into the heat insulation panel 1 and fastened with the coupler 10 embedded in the precast concrete plate 2, the insertion position of the fixture 9 is accurately adjusted. It must be. This is because if the insertion position of the fixture 9 into the heat insulating panel 1 is greatly shifted, it may not be possible to fasten with the coupler 10 embedded in the precast concrete plate 2. On the other hand, when the anchor member 90 is used, the anchor member 90 must be inserted at a position where it does not collide with the coupler 10, but it is clearly compared with the case where the anchor member 90 is adjusted to a position where the anchor member 90 is fastened. It is easy to position. Therefore, the time and labor required for newly installing the heat insulation panel 1 can be greatly reduced, and the risk of displacement between the newly installed heat insulation panel 1 and the precast concrete plate 2 can be reduced.

  As described above, in the composite panel A of the present invention, the heat insulation panel 1 can be removed or a new heat insulation panel 1 can be newly installed in a short time and with easy work. Therefore, when the surface of the heat insulation panel 1 is damaged and the design of the appearance is lowered, or when the heat insulation material 3 is deteriorated and the heat insulation performance is lowered, the heat insulation panel 1 is removed. If the new heat insulation panel 1 is attached, the designability and heat insulation performance of the composite panel A can be ensured for a long time. Moreover, since the heat insulation panel 1 is lighter than a conventional outer wall molded plate or the like, the burden on the operator at the time of new installation work is also reduced.

  The composite panel A of the present invention can be formed on the outer wall of a building to form the outer heat insulating wall 70. Specifically, as shown in FIG. 6, a plurality of composite panels A, A,... Are prepared, and the outer heat insulating wall 70 is constructed by attaching them in the vertical and horizontal directions of the outer wall. be able to.

  In the above construction, as shown in FIG. 7, in order to improve water tightness between the composite panels A and A adjacent to the left and right, a gasket 65 is disposed in the longitudinal direction at the rear portion of the gap 55 between the composite panels A and A. Can be provided over the entire length. Similarly, in order to improve water tightness, a sealing 66 and a backup material 67 are provided in this order between the heat insulating panels 1 and 1 which are the front part of the gap 55 between the composite panels A and A, and immediately behind the sealing 66 and the backup material 67. Similarly, a sealing 66 and a backup material 67 are also provided between the precast concrete plates 2 and 2 in this order.

  Although the composite panel A can replace the heat insulation panel 1, it is possible to replace the heat insulation panel 1 in the same manner even after it is constructed on the outer wall and formed as the outer heat insulation wall 70 as shown in FIG. It can be done.

  The manufacturing method of the composite panel A of the present invention can be manufactured in advance at a factory or the like (or a construction site). Hereinafter, the detail of the manufacturing method of the composite panel A is demonstrated.

  When the heat insulating panel 1 used for manufacturing the composite panel A is formed by fitting a pair of heat insulating panel segments 1s, the heat insulating panel 1 can be manufactured by the following procedure. First, the heat insulation panel division | segmentation 1s which has the fitting part S1 in one side edge part and the heat insulation panel division | segmentation 1s which has the to-be-fitted part S2 in one side edge part are prepared, respectively. The fitting portion S1 and the fitted portion S2 are the same as those shown in FIGS. 3 (a) and 3 (b), respectively. And the fixing tool 9 is inserted from the recessed part 41 in the to-be-fitted part S2, and the back surface metal plate 12 is penetrated. In this case, the fixing tool 9 can be provided with a predetermined interval across the entire length of the recess 41. Next, the heat insulating panel segments 1 s and 1 s are fitted by the fitting portion S <b> 1 and the fitted portion S <b> 2, and the flat screw 50 is inserted from the back side of the rear folding portion 44, so that the rear folding portion 44 and the convex portion are inserted. The heat insulation panel 1 with which the heat insulation panel division | segmentation 1s and 1s were fitted is obtained by making it the state penetrated by 31 with the flat screw 50. FIG. When the flat screw 50 is inserted, the width of the gap 47a formed at the joint, that is, the width of the vertical joint 48 formed on the surface of the heat insulating panel 1 can be adjusted by finely adjusting the insertion position. Adjustable by length.

  Next, as shown in FIG. 8, the fixtures 9 are inserted at predetermined positions near the both ends of the surface of the heat insulating panel 1 (on the surface metal plate 11 side) with a predetermined interval over the entire length of the heat insulating panel 1. The back metal plate 12 is penetrated. After inserting the fixture 9 so as to penetrate the recess 41 and both ends of the surface of the heat insulation panel 1 in this way, as shown in FIG. 9B, the tip of the fixture 9 (the back surface metal plate 12 side). Then, the plurality of spacers 13 are passed, and then the nut 14 and the coupler 10 are fastened in this order. At this time, the back surface side of the heat insulation panel 1 will be in a state as shown to Fig.9 (a).

  Here, as shown in FIG. 10, a filler 33 may be attached to the upper and lower ends of the back surface of the heat insulating panel 1 with an adhesive or the like over the entire length in the lateral direction. Moreover, you may improve airtightness by sticking the airtight tape 51 in the clearance gap 47b formed in the fitting part of heat insulation panel division | segmentation 1s between the full length.

  Next, the heat insulation panel 1 manufactured as described above is accommodated in a square-shaped mold 60 having an opening at the entire upper end as shown in FIG. 11A. As the mold 60, for example, a rectangular plate having four rectangular shapes may be used so as to have a rectangular shape in plan view. Note that the mold 60 substantially matches the size and shape of the heat insulating panel 1, and the depth of the mold 60 corresponds to the thickness of the composite panel A. When accommodating the heat insulation panel 1, as shown in FIG.11 (b), it accommodates in the formwork 60 so that the back surface side of the heat insulation panel 1 may face upwards. At this time, the four circumferences of the mold 60 are temporarily fixed so that the thermal insulation panel 1 is accommodated in the mold 60, and the four corners of the mold 60 are placed on the outer circumference of the thermal insulation panel 1 after the thermal insulation panel 1 is accommodated. What is necessary is just to fix so that it may tighten. When a gap is formed between the outer periphery of the heat insulating panel 1 and the mold 60, a sealing material or the like can be filled in the gap. And in order to reinforce the intensity | strength of the composite panel A, the reinforcement lattice 61 is mounted on the upper side of the heat insulation panel 1 accommodated in the mold 60, as shown in FIG.11 (c). The reinforcing bar lattice 61 may be planar or three-dimensional, and in the case of a planar shape, a plurality of reinforcing bar lattices 61 can be placed so as to overlap each other.

  Next, as shown in FIG. 11 (d), the concrete material 20 is filled up to the uppermost surface in the mold 60 to smooth the surface of the concrete material 20. When the sealing agent is filled in the four circumferences of the heat insulating panel 1 as described above, the concrete material 20 can be prevented from flowing into the gap between the heat insulating panel 1 and the mold 60. Further, for example, two diagonal bars of the mold 60 may be fixed in advance with two wooden bars 62 and 62 so that the four-round frame of the mold 60 does not move when the concrete material 20 is poured. . In this way, after filling the mold material 60 with the concrete material, the concrete material 20 is cured and cured by standing for a predetermined time, and the precast concrete plate 2 is formed. Finally, by removing the quadrilateral frame of the mold 60, it is possible to obtain a composite panel A in which a precast concrete plate is superimposed on the heat insulating panel 1. In the composite panel A manufactured in this way, as shown in FIG. 1, a fixture 9 provided through the surface of the surface metal plate 11 in the thickness direction of the heat insulating panel 1 is embedded in the precast concrete plate 2. It has a structure fastened to the coupler 10.

  In the manufacturing method of the composite panel A of the present invention, a method is adopted in which the precast concrete board 2 is placed by accommodating the heat insulation panel 1 in the rectangular formwork 60 opened upward so that the back surface of the heat insulation panel 1 faces upward. Is. Therefore, compared to the case where the precast concrete plate 2 is placed with the heat insulation panel 1 standing upright, the stress applied to the heat insulation panel 1 is likely to be equalized, so that the composite panel A after production maintains a stable shape. Can do.

  And in the composite panel A obtained by such a manufacturing method, since the fixing tool 9 and the coupling tool 10 are fastened simultaneously with manufacture after the precast concrete board 2 is formed, the heat insulation to the precast concrete board 2 is performed. The panel 1 can be easily attached and the possibility of displacement of both is reduced.
