  When constructing concrete slabs or building side walls using the standard mold / heat insulation panel 40A as described above, the mold / heat insulation panel is simply built in a flat part (general part). There is also a need to build in corners such as the corners and corners. Therefore, in the conventional heat insulating panel for a formwork, as shown in FIG. 12, in addition to the standard heat insulating panel for a formwork 40A to be built in a flat portion (general part), it is used when forming a corner portion. There are three types of heat-insulating panels 40A, 40B, and 40C for both the formwork and the heat-insulating panel 40B for forming the corners and the heat-insulating panel 40C for the corners that are used when forming the corners. In need of.

  That is, in the conventional combined formwork heat insulating panel, as shown in FIG. 12, the above-described crosspiece 30 is disposed on both sides of the heat insulating plate 41, and the standard formwork combined heat insulating panel 40A and the crosspiece on one side are provided. 30b is a frame and heat insulation panel 40B for entering corners that is disposed inward from the end of the heat insulation plate 41 by a distance d, and a protruding corner in which the crosspiece 30b on one side is flush with the surface of the heat insulation plate 41. Three types of heat-insulating panel 40C, which is used as a formwork, are fixed by using a corner metal fitting 50 at the corner of the entrance and adjacent pier 30b and pier 30 are fixed by nailing or the like, and a flat plate member 51 is used at the corner of the exit. Also, the adjacent pier 30b and pier 30 are fixed by nailing or the like.

  That is, the three types of combined formwork / heat insulation panels 40A, 40B, and 40C are stored without deficiency during the erection operation, and the formwork / heat insulation panel suitable for the installation location is selected and installed. Therefore, it was inevitable that the installation work would become somewhat complicated.

  The present invention has been made in view of the circumstances as described above. In the heat insulating panel for formwork, which is formed by inserting a crosspiece into a concave groove formed in a heat insulating plate that is a synthetic resin foam, one type is provided. It is an object of the present invention to provide a heat-insulating panel for formwork that can be built not only in the general part but also in the corners of the entrance corner and the exit corner.

  A heat insulating panel for both form and mold according to the present invention includes a heat insulating plate that is a synthetic resin foam, and a plurality of crosspieces embedded in a plurality of concave grooves formed on one surface of the heat insulating plate. A heat insulating panel for a frame, wherein the heat insulating plate is formed with a first cutout portion parallel to the concave groove along one side, and the adjacent frame and heat insulating panel on the other side. A second cutout portion with which the formed first cutout portion is engaged is formed along the side, and a second side in the side region where the second cutout is formed. A flat plate member is fixed to the surface side opposite to the notch.

  When building a formwork using the above-mentioned heat insulation panel for both formwork, make sure that the surface on which the pier is attached is opposite to the concrete pouring side, that is, in the case of a concrete wall, the pier side is the indoor side. The protrusion formed by the notch portion of the adjacent mold form and heat insulation panel is positioned in the first and second cutout portions formed on both sides of the mold form and heat insulation panel. And And the crosspiece located in the side part of two panels and the said flat plate member are fixed with an appropriate jig. By adopting this mode, it is possible to build all of the general part, the protruding corner part, and the entering corner part using only one type of heat-insulating panel that is also used as a formwork. The simplification work is simplified. After that, as in the conventional method, a required number of separators are mounted on the heat-insulating panel for combined formwork and the panel material, and then end thick materials are assembled and stabilized on both outer surface portions, and then concrete is placed.

  Further, in the heat insulating panel for both formwork of the present invention, the engaging portion between the heat insulating panels for both the formwork is in a state in which the cutout portion and the protruding portion are engaged as described above. Since there is no gap between the panel surfaces after installation for some reason, the panels are in contact with each other. There is also an effect that the heat does not flow out from the part and no heat insulation defect occurs.

  In a preferable aspect of the heat-insulating panel for formwork according to the present invention, the second flat plate member is fixed to the side region where the flat plate member is fixed and the side region where the first notch is formed. Is done. In the form / heat insulation panel of this aspect, the connection between two adjacent form / heat insulation panels is fixed to the flat plate member and the second flat plate member located on the side portions of the two panels by an appropriate jig. Since this can be done, a stronger bond state can be obtained.

  In the present invention, examples of the synthetic resin foam as a material for the heat insulating plate include polystyrene foam, polyethylene foam, polypropylene foam, rigid urethane foam, phenol foam, and isocyanate foam. Of these, a foam-in-bead-molded product in which the polystyrene-based expandable resin particles are filled in a mold, heated and expanded with heated steam or the like, and fused together is suitably used. The thickness of the heat insulating plate is not particularly limited, and is arbitrarily selected according to the construction environment.

  In the present invention, there is no particular limitation on the material constituting the crosspiece and the flat plate member, but when a fixture such as a mounting bracket is fixedly connected between adjacent formwork and heat insulating panels, a nail or Wood materials such as wood, synthetic wood, and processed wood materials are suitable because of their stable holding power against screws and light weight. In addition, low foamed resin materials such as polystyrene, polypropylene, and urethane may be used.

  According to the present invention, by using only one type of heat-insulating panel for formwork, it is possible to firmly embed the heat-insulating formwork for both formwork not only in the general part but also in the corners of the entrance corner and the exit corner. It becomes possible.

  Hereinafter, a preferred embodiment of a heat insulating panel for formwork according to the present invention will be described with reference to the drawings.

  FIG. 1 is a front view (FIG. 1a) and a rear view (FIG. 1b) showing an embodiment of a combined formwork heat insulating panel 20 according to the present invention. In this example, 900 × 2600 × 50 ( mm), a heat insulating plate 21 which is a foamed polystyrene plate, a crosspiece 30 shown in FIG. 3, and a flat plate member 36 shown in FIG. The heat insulating plate 21 is integrally formed by foaming within a bead mold, and in the illustrated example, the required number (5 in the illustrated example) extending in the longitudinal direction with a predetermined distance on the surface side of the heat insulating plate 21. The concave grooves 22 and 22a are formed.

  As shown in FIG. 5 which is a cross-sectional view taken along line aa in FIG. 1a and FIG. 6 which is a cross-sectional view taken along line bb in FIG. 1a, each concave groove 22 has a rectangular cross-sectional shape and is insulated over its entire length. The depth is about 1/3 to 1/2 of the thickness of the plate 21, and a required number of recessed portions 24 having a required depth are formed at a predetermined interval at the bottom. A through hole 25 is formed on the bottom surface of each recessed portion 24 so as to pass through the other surface of the heat insulating plate 21. The recessed portion 24 and the through hole 25 may be omitted.

  A first notch 26 is formed on one side of the heat insulating plate 21 that is the long side, and is formed outside the concave groove 22a so as to be continuous with the concave groove 22a. The other side of the long side of the heat insulating plate 21 is second on the surface opposite to the surface on which the first notch is formed (the surface on which the concave groove 22 is not formed). A notch 27 is formed. The width and depth of the first and second cutout portions 26 and 27 are about ½ of the thickness of the heat insulating plate 21. Due to the first and second cutout portions 26 and 27, the first projecting portion having a thickness of about ½ of the thickness of the heat insulating panel 20 for both the frame and the both sides on the long side of the heat insulating plate 21. 28 and a second protrusion 29 are formed. In this example, the concave grooves 22b and 22b are also formed at both ends on the short side of the heat insulating plate 21, but may be omitted.

  The crosspiece 30 is used by being embedded in the concave groove 22 of the heat insulating material 21, and has a protrusion 32 such as a nail 31. The pier 30 and the manner of attachment in the recessed groove 22 are the same as those described with reference to FIG. 11, and detailed description thereof is omitted. Similarly, the protrusion 32 can be omitted.

  As shown in FIGS. 1 and 5, the flat plate member 36 shown in FIG. 4 has a surface opposite to the second notch 27 in the side region where the second notch 27 is formed. It is fixed to the side with an adhesive or the like. The flat plate member 36 has a thickness of about 5 to 20 mm, and preferably the upper surface thereof is substantially flush with the surface of the pier 30. As described above, the flat plate member 36 needs to have a stable holding force with respect to a nail or a screw, which is a stopper for fixing a jig described later, such as wood, synthetic wood, or processed wood material. A suitable woody material is preferably used.

  By attaching the crosspiece 30 shown in FIG. 3 and the flat plate member 36 shown in FIG. 4 to the heat insulating plate 21 shown in FIG. 2, the form and heat insulating panel 20 shown in FIG. 1 is formed.

  Next, an example in the case of constructing a concrete wall using the above-mentioned heat insulating panel for formwork 20 will be described with reference to FIGS. In this example, the formwork combined heat insulation panel 20 shown in FIGS. 1 to 6 is used as the formwork combined heat insulation panel of the concrete wall 40 on the indoor side of the building.

  In the case where the formwork and heat insulation panel 20 is continuously built in the general part (planar part), the first cutout part 26 and the second cutout part 27 are combined as shown by the arrow A in FIG. As a phase chip joint, a flat mounting member 53 as a jig is struck with a nail or the like to the flat plate member 36 of one panel 20 and the crosspiece 30 of the other panel 20. As a result, the two sheet-form heat insulation panels 20 and 20 are firmly connected.

  At the protruding corner indicated by the arrow B, the first projecting portion 28 of the other panel 20 is connected to the second cutout portion 27 of the one panel 20 of the mold / heat insulating panels 20 and 20 arranged at right angles. The L-shaped corner metal fitting 54 that is engaged and is attached to the flat plate member 36 and the pier 30 with a nail or the like. Thereby, the two sheet-form heat insulation panels 20 and 20 can be firmly connected.

  In the entrance corner indicated by the arrow C, the second projecting portion 29 of the other panel 20 is provided in the first cutout portion 26 of the one panel 20 of the mold / heat insulating panels 20 and 20 arranged at right angles. The inverted L-shaped corner metal fitting 50 that is an attachment jig is hit against the flat plate member 36 and the pier 30 with a nail or the like.

  As described above, by using the heat insulating panel 20 for both the formwork according to the present invention, not only the general part but also the corner part of the entrance corner and the exit corner are built in by one type of heat insulation panel 20 for both the formwork. Can do.

  Then, as shown in FIG. 8, the conventional panel material 6 is used for the outer formwork so that the pier 30 side becomes the indoor side, in the same way that the formwork is built with the conventional formwork and heat insulation panel. After the required number of separators 9 are mounted on the panel / heat insulating panel 20 and the panel material 6, which are built in, the end thick materials 7 and 8 are assembled on both outer surface portions to be stabilized, thereby forming a side wall mold. Thereafter, the concrete D is poured into a space portion that will form a wall portion.

  In the heat insulating panel 20 for combined formwork according to the present invention, the notched portions 26 and 27 and the protruding portions 28 and 29 are engaged with each other in the connecting portion between the heat insulating panels 20 for combined formwork, and it is not a simple butt joint. Even if a gap is generated on the surface, the panels are in contact with each other, so that it is possible to prevent the “loose” of the concrete from flowing out from there.

  In addition, although the above demonstrated the case where a concrete wall was constructed, it does not need description that this formwork combined heat insulation panel can be used also when constructing a ceiling concrete slab.

  FIG. 9 is a perspective view showing still another embodiment of the heat-insulating panel for formwork according to the present invention. The heat-insulating panel for formwork 20A is a heat-insulating panel for formwork of the form shown in FIGS. 20, the second flat plate member 36 </ b> A is also fixed with an adhesive or the like to the side region where the flat plate member 36 is fixed and the side region where the first cutout portion 26 is formed. In that respect, the configuration is different from that of the form and heat insulating panel 20 of the form shown in FIGS. The other configuration is basically the same as that of the mold / heat insulating panel 20 shown in FIGS. 1 to 6 and is denoted by the same reference numerals.

  Although not shown, in the case of using the mold / heat insulating panel 20A, the connection between the two adjacent mold / heat insulating panels 20A and 20A is performed by using the flat plate member 36 and the second flat plate member 36A as a jig. Since it can carry out by fixing with a connection metal fitting, a more stable connection state is obtained.
