[0002] Conventionally, a foundation insulation formwork (insulation formwork) has been known that serves as a formwork for pouring concrete when constructing a foundation and is left as a heat insulating material after the foundation is constructed (see Patent Document 1). The foundation insulation formwork uses a foundation insulation formwork main body made of a foam-based insulating material, and the foundation insulation formwork main body is reinforced to suppress deformation when pouring concrete. The reinforcement structure of this foundation insulation formwork body is composed of multiple reinforcing materials arranged extending vertically along the foundation insulation formwork body, base spacers, top spacers and separators that connect the foundation insulation formwork bodies at intervals in the width direction and are arranged at the lower, upper and middle ends of the reinforcing materials, respectively, and single pipes that extend in a direction intersecting the reinforcing materials and are fitted into the multiple top spacers.

[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 5, the insulated formwork reinforcement structure 10 of this embodiment is a structure for reinforcing an insulated formwork 1 used as a formwork for pouring concrete to form an insulated foundation (foundation) of a house or the like. The insulated formwork 1 is made of a foam-based insulating material. The insulated formwork 1 is composed of two rows of rectangular plate-shaped formwork members 2 arranged along the X-axis direction and rectangular plate-shaped end formwork members 3 arranged at the ends of the formwork members 2 in the X-axis direction. The two rows of formwork members 2 are paired facing each other in the Y-axis direction, and multiple formwork members 2 are arranged side by side in each row along the X-axis direction. The end formwork members 3 are shorter than the formwork members 2 and arranged along the Y-axis direction, abutting the ends of the pair of formwork members 2. In this embodiment, rail members 4 are provided along the upper edges of the formwork members 2 and the end formwork members 3, connecting them to each other. Note that rail members may be provided along the lower edges of the formwork members 2 and the end formwork members 3. In the following description, the longitudinal direction of the heat insulating formwork 1 is defined as the X-axis direction, the vertical direction of the heat insulating formwork 1 as the Y-axis direction, and the width direction of the heat insulating formwork 1 as the Z-axis direction. The X, Y, and Z-axis directions are perpendicular to each other.

[0010] [Insulated formwork reinforcement structure] The heat-insulating formwork reinforcement structure 10 is constructed by assembling a lower width stopper 20, an upper width stopper 30, a vertical reinforcement 40, an upper reinforcement 50, and a lower reinforcement 60, which reinforce a pair of formwork members 2. The heat-insulating formwork reinforcement structure 10 of this embodiment also includes a lower width stopper 20B, a lower reinforcement 60B, a vertical reinforcement 40B, and an upper reinforcement 50B, which reinforce the end formwork member 3.

[0011] The lower width stopper 20 is made of metal, aluminum in this embodiment, and as shown in FIG. 4 , it has a main body piece 21 extending in the Y-axis direction, outer holding pieces 22 extending upward from both ends of the main body piece 21, and a pair of inner holding pieces 23 extending upward between the pair of outer holding pieces 22. The inner holding pieces 23 are longer in the Z-axis direction than the outer holding pieces 22 and extend above the height of the lower reinforcement 60. The distance between the outer holding piece 22 and the inner holding piece 23 is set to be sufficient to allow the lower part of the thermally insulated formwork 1 to be positioned therebetween and to allow insertion of a connecting piece 62 (described later) of the lower reinforcement 60. In other words, the distance between the outer holding piece 22 and the inner holding piece 23 is set to be slightly larger than the thickness of the thermally insulated formwork 1. In addition, if the connecting piece portion 62 can be inserted by slightly deforming the insulated formwork 1 made of a foam-based insulating material, the distance between the outer retaining piece portion 22 and the inner retaining piece portion 23 may be the same as the thickness dimension of the insulated formwork 1.

[0012] The upper width stopper 30 is made of metal, aluminum in this embodiment. As shown in FIGS. 1 and 4 , the upper width stopper 30 is composed of two components: a short member 31 and a long member 32, arranged along the Y-axis direction. One end of the short member 31 and one end of the long member 32 are formed with connecting pieces 33 that extend upward and overlap each other. The other end of the short member 31 and the other end of the long member 32 are formed with outer retaining pieces 34 that hang downward. A pair of inner retaining pieces 36 that hang downward are formed between the pair of outer retaining pieces 34. The connecting pieces 33 are formed with elongated holes along the Z-axis direction, and the connecting pieces 33 are fastened together by screws 35 inserted through the elongated holes. This allows the vertical positions of the short member 31 and the long member 32 to be adjusted according to the height of the upper edges of the pair of formwork members 2. This allows the upper width stopper 30 to be installed horizontally, for example, when installing foundation anchors or the like in the upper width stopper 30. The distance between the outer holding piece 34 and the inner holding piece 36 is set to a distance that allows the lower part of the heat-insulating formwork 1 to be placed therebetween.

[0013] The lower reinforcement 60 is made of metal, and in this embodiment is made of extruded aluminum, and has a hollow rectangular main body 61 extending in the X-axis direction and a connecting piece 62 extending downward from the main body 61.As shown in particular in Figure 4, the main body 61 is positioned further out in the Z-axis direction than the position of the connecting piece 62 by the amount of the connecting piece 432 of the vertical reinforcement 40.

[0014] The vertical reinforcement member 40 is made of metal, and in this embodiment is made of extruded aluminum extrusion, and has a main body portion 41 with a hollow rectangular cross section extending in the Y-axis direction, an upper connecting portion 42 provided at the top of the main body portion 41, and a lower connecting portion 43 provided at the bottom of the main body portion 41. As shown in FIG. 4 , the upper connecting portion 42 has a pair of side pieces 421, 422 extending along the Y-axis direction and a bottom piece 423 extending along the Z-axis direction. The groove 45 has a U-shaped cross section and opens upward. The groove 45 also has the side piece 421, an upper piece 424 connected to the upper end of the side piece 421, and a side piece 425 extending downward from the end of the upper piece 424. The hook 46 also has a U-shaped cross section and opens downward. The hook 46 is located on the inner side of the groove 45 in the Z-axis direction. The side piece 421 is longer in the Y-axis direction than the side pieces 422, 425. The bottom piece 423 is located at the upper end of the main body 41. The dimension of the bottom piece 423 in the Z-axis direction is approximately equal to the dimension of the upper reinforcement member 50 in the Z-axis direction. The dimension of the upper piece 424 in the X-axis direction is approximately equal to the width of the formwork member 2 in the Z-axis direction. As shown particularly in Figure 4, the lower connecting portion 43 has a base piece portion 431 arranged at the lower end of the main body portion 41, and a connecting piece portion 432 extending downward from the inner end portion of the base piece portion 431 in the Z-axis direction.

[0015] The upper reinforcing member 50 is made of metal, and in this embodiment is made of an extruded aluminum section, and extends in the X-axis direction, and as shown in FIG. 4 in particular, is formed in a hollow rectangular cross section.

[0016] The lower reinforcement member 60B, the vertical reinforcement member 40B, and the upper reinforcement member 50B are formed in substantially the same manner as the lower reinforcement member 60, the vertical reinforcement member 40, and the upper reinforcement member 50 described above, with the lower reinforcement member 60B and the upper reinforcement member 50B arranged along the Z-axis direction, and the vertical reinforcement member 40B arranged along the Y-axis direction. The lower reinforcement member 60B and the upper reinforcement member 50B are shorter than the lower reinforcement member 60 and the upper reinforcement member 50. Furthermore, in addition to the configuration of the lower width stopper member 20 described above, the lower width stopper member 20B (end lower width stopper member) has a bridging piece 25 extending in the X-axis direction from the middle of the main body piece 21, as shown in particular in FIGS. 3 and 5 , and is formed in a generally T-shape in plan view. The bridging piece 25 has an outer holding piece 251 extending upward from its end and an inner holding piece 252 extending upward at a position closer to the main body piece 21 than the outer holding piece 251. The outer holding piece 251 and the inner holding piece 252 are formed in substantially the same manner as the outer holding piece 22 and the inner holding piece 23 described above.

[0017] The above-mentioned lower width stoppers 20, 20B, upper width stoppers 30, lower reinforcements 60, 60B, vertical reinforcements 40, 40B, and upper reinforcements 50, 50B are assembled around the thermally insulated formwork 1 to form the thermally insulated formwork reinforcement structure 10. According to this thermally insulated formwork reinforcement structure 10, in particular, the provision of lower reinforcements 60, 60B makes it possible to reinforce the portions between the lower parts of the plurality of vertical reinforcements 40, 40B. This reinforcement makes it possible to suppress deformation such as outward bulging of the portions of the thermally insulated formwork 1 between the lower parts of the plurality of vertical reinforcements 40, 40B when concrete is poured into the thermally insulated formwork 1 during foundation construction, facilitating desired construction. In the insulating formwork reinforcement structure 10, the multiple lower width stop members 20 connect the lower edges of a pair of formwork members 2 arranged opposite each other in the Z-axis direction to reinforce them, the lower width stop members 20B (end lower width stop members) connect the lower edges of end formwork members 3 arranged at each end of the pair of formwork members 2 to the pair of formwork members 2 to reinforce them, the multiple upper width stop members 30 connect the upper edges of the pair of formwork members 2 to reinforce them in the Z-axis direction, the lower reinforcement member 60 reinforces the lower parts of the pair of formwork members 2 along the X-axis direction, the lower reinforcement member 60B reinforces the lower parts of the end formwork members 3 along the X-axis direction, the multiple vertical reinforcement members 40 reinforce the pair of formwork members 2 along the Z-axis direction, the vertical reinforcement member 40B reinforces the end formwork member 3 along the Z-axis direction, the upper reinforcement member 50 reinforces the upper parts of the pair of formwork members 2 along the X-axis direction, and the upper reinforcement member 50B reinforces the upper parts of the end formwork members 3 along the X-axis direction. The lower reinforcing members 60, 60B and the upper reinforcing members 50, 50B may be connected to each other with an L-shaped metal fitting or the like to increase strength.

[0018] [Insulated foundation construction method] A method for constructing a heat-insulating foundation (foundation) having heat insulating properties using the heat-insulating formwork reinforcement structure 10 will be described. First, the bottom width stoppers 20, 20B are arranged on a base (not shown) on which the heat-insulating formwork 1 is to be installed. A plurality of bottom width stoppers 20 are arranged at predetermined intervals along the X-axis direction, and the bottom width stoppers 20B are arranged at both ends of the plurality of bottom width stoppers 20 in the X-axis direction. Each main body piece 21 is arranged along the Z-axis direction. Next, a pair of formwork members 2 are arranged opposite each other in the Z-axis direction, and the lower edges of the pair of formwork members 2 are disposed between the outer retaining piece portion 22 and the inner retaining piece portion 23 of the bottom width stop members 20, 20B, and the end formwork members 3 are arranged at both ends of the pair of formwork members 2 in the X-axis direction and their lower edges are disposed between the outer retaining piece portion 251 and the inner retaining piece portion 252 of the bridging piece portion 25 of the bottom width stop member 20B, thereby connecting the end formwork members 3 to the main body piece portion 21. This forms the insulated formwork 1 of this embodiment, and the lower edges of the pair of formwork members 2 and the lower edge of the end formwork member 3 are connected to each other by the bottom width stop members 20, 20B. Next, the lower reinforcement member 60 is connected to the lower width stop member 20 by inserting the connecting piece portion 62 of the lower reinforcement member 60 between the outer holding piece portion 22 of the multiple lower width stop members 20 and the outer surface of the formwork member 2, and the lower reinforcement member 60B is connected to the lower width stop member 20B by inserting the connecting piece portion 62 of the lower reinforcement member 60B between the outer holding piece portion 22 of the lower width stop member 20B and the outer surface of the formwork member 2. A pair of lower reinforcement members 60 are provided along the pair of formwork members 2, and two lower reinforcement members 60B are provided along the two end formwork members 3. The ends of the lower reinforcement members 60, 60B abut against each other. Next, a plurality of upper width stoppers 30 are placed along the upper edges of the pair of formwork members 2, and the outer holding pieces 34 and inner holding pieces 36 of the upper width stoppers 30 hold the pair of formwork members 2 so as to sandwich them together. In this way, the upper edges of the pair of formwork members 2 are connected by the upper width stoppers 30. Next, the connecting piece portions 432 of the multiple vertical reinforcements 40 are inserted between the main body portion 61 of the lower reinforcement 60 and the formwork material 2, thereby connecting the lower portions of the vertical reinforcements 40 to the lower reinforcement 60, and the hanging portions 46 of the multiple vertical reinforcements 40 are hung on the upper edge of the formwork material 2, thereby connecting the upper portions of the vertical reinforcements 40 to the formwork material 2, so that the multiple vertical reinforcements 40 extend in the Y-axis direction and are aligned with the outer surfaces of the pair of formwork materials 2. In addition, by inserting the connecting piece portion 432 of the vertical reinforcement 40B between the main body portion 61 of the lower reinforcement 60B and the end formwork material 3, the lower portion of the vertical reinforcement 40B is connected to the lower reinforcement 60B, and by hanging the hanging portion 46 of the vertical reinforcement 40B on the upper edge of the end formwork material 3, the upper portion of the vertical reinforcement 40B is connected to the end formwork material 3, so that the two vertical reinforcements 40B extend in the Y-axis direction and are aligned with the outer surfaces of the end formwork materials 3. Next, the upper reinforcement 50 is connected to the vertical reinforcement 40 by fitting the upper reinforcement 50 into the grooves 45 of the multiple vertical reinforcement 40, and the upper reinforcement 50B is connected to the vertical reinforcement 40B by fitting the upper reinforcement 50B into the grooves 45 of the vertical reinforcement 40B. Note that a pair of upper reinforcement 50 is provided along the pair of formwork members 2, and two upper reinforcement members 50B are provided along the two end formwork members 3. The ends of the upper reinforcement 50, 50B abut against each other. In this way, the thermally insulated formwork reinforcement structure 10 is formed around the thermally insulated formwork 1. Next, concrete is poured into the heat-insulating formwork 1 and cured. At this time, an outward force is applied to the heat-insulating formwork 1, but because the heat-insulating formwork 1 is reinforced by the heat-insulating formwork reinforcement structure 10, deformation of the heat-insulating formwork 1 that causes it to bulge outward is suppressed. After curing, the upper width stopper 30, upper reinforcement members 50, 50B, vertical reinforcement members 40, 40B, and lower reinforcement members 60, 60B are removed to dismantle the heat-insulating formwork reinforcement structure 10. When removing the upper width stopper 30, upper reinforcement members 50, 50B, vertical reinforcement members 40, 40B, and lower reinforcement members 60, 60B, no fasteners such as screws are used to connect the components, and they are connected by insertion or fitting, making it easy to remove the components. However, the lower width stopper members 20, 20B are left in place. In this way, the construction of the insulated foundation by the insulated foundation construction method using the insulated formwork reinforcement structure 10 is completed.

[0019] [Variations] In the above embodiment, the lower width stoppers 20, 20B, the upper width stoppers 30, the lower reinforcements 60, 60B, the vertical reinforcements 40, 40B and the upper reinforcements 50, 50B are made of aluminum and are lightweight and strong, but this is not limited thereto and they may be made of other metal materials or may be made of materials other than metal as long as they have sufficient strength to reinforce the insulated formwork 1. In the above embodiment, a lower width stopper member 20B is arranged at the end of each of the multiple lower width stopper members 20 in the X-axis direction, but instead of this lower width stopper member 20B, a normal lower width stopper member 20 may be arranged. In the above embodiment, the upper width stopper member 30 is formed by joining two members, the short member 31 and the long member 32, but this is not limiting, and the upper width stopper member 30 may be formed from a single member. In the above embodiment, the upper width stopper member 30 does not include a member that is approximately T-shaped in plan view like the lower width stopper member 20B, but may instead include an upper end width stopper member having a bridging piece along the X-axis direction and a main piece along the Z-axis direction for connecting the end form members 3. This main piece connects a pair of form members 2, and the bridging piece connects the main piece to the upper edge of the end form member 3. With this configuration, by using the above-mentioned upper end width stopper member, it is possible to prevent the upper edge of the end form member 3 from shifting outward, mainly in the X-axis direction. In the above embodiment, the main body portion 61 of the lower reinforcement 60 is positioned at a position outside the position of the connecting piece portion 62 in the Z-axis direction, and the main body portion 61 of the lower reinforcement 60B is positioned at a position outside the position of the connecting piece portion 62 in the X-axis direction, but this is not limited to this. As long as the connecting piece portion 432 of the vertical reinforcement 40, 40B can be inserted between the main body portion 61 and the insulated formwork 1, the main body portion 61 may be positioned directly above the connecting piece portion 62 rather than being positioned at the above position outside the connecting piece portion 62. In the above embodiment, the lower reinforcement members 60, 60B are connected to the lower width stop members 20, 20B by inserting the connecting piece portion 62 between the outer retaining piece portion 22 of the lower width stop members 20, 20B and the insulated formwork 1, but this is not limited to this, and the lower reinforcement members 60, 60B may also be connected to the lower width stop members 20, 20B by fasteners such as screws. In the above embodiment, the upper width stopper 30 is arranged after the lower reinforcement members 60, 60B are arranged, but this is not limited to this, and the upper width stopper 30 may be arranged at any time after the insulated formwork 1 is constructed and before concrete is poured. In the above embodiment, no separators (not shown) are used to connect a pair of formwork materials 2, and no tension rods (not shown) are used to support the upper and lower parts of the vertical reinforcement materials, but this is not limiting and separators and tension rods may also be used.

[0020] [Summary of the present invention] (1) The insulated formwork reinforcement structure of the present invention is an insulated formwork reinforcement structure that reinforces an insulated formwork used as a formwork for pouring concrete for a foundation and that has at least a pair of formwork members that face each other in the width direction, and is characterized by comprising a plurality of lower width stop members arranged by connecting the lower edges of the pair of formwork members, a plurality of upper width stop members arranged by connecting the upper edges of the pair of formwork members, a plurality of vertical reinforcements that extend in an up-down direction that intersects the width direction and are arranged along the formwork members and have their upper parts connected to the formwork members, an upper reinforcement that extends in a longitudinal direction that intersects the width direction and the up-down direction and is connected to the upper parts of the plurality of vertical reinforcements, and a lower reinforcement that extends in the longitudinal direction and is connected to the plurality of lower width stop members and to which the lower parts of the plurality of vertical reinforcements are connected. According to the insulated formwork reinforcement structure of the present invention, by providing a lower reinforcement member as described above, the parts between the lower parts of multiple vertical reinforcements can be reinforced.This reinforcement makes it possible to suppress deformation such as outward bulging of the parts of the insulated formwork between the lower parts of multiple vertical reinforcements when concrete is poured into the insulated formwork during foundation construction, making it easy to carry out the desired construction. (2) In the heat-insulating formwork reinforcement structure of the present invention, the lower width stopper, the upper width stopper, the vertical reinforcement, the upper reinforcement, and the lower reinforcement may be made of metal. With this configuration, the strength of the components can be increased and deformation such as outward bulging of the insulated formwork can be more effectively suppressed compared to when at least one of the lower width stopper, upper width stopper, vertical reinforcement, upper reinforcement and lower reinforcement, for example, the vertical reinforcement, is formed from synthetic wood or the like. (3) In the heat-insulating formwork reinforcement structure of the present invention, the vertical reinforcement members may be formed of metal extrusions having a hollow rectangular cross section. With this configuration, the rigidity can be increased and the weight of the vertical reinforcement member itself can be reduced, compared to a vertical reinforcement member made of synthetic wood, for example. (4) In the heat-insulating formwork reinforcement structure of the present invention, the lower reinforcement member may have a connecting piece portion that is inserted between the formwork member and the plurality of lower width stoppers. With this configuration, the lower reinforcement can be easily and removably installed along the formwork material simply by inserting the connecting piece portion of the lower reinforcement material between the formwork material and the plurality of bottom width stoppers. (5) In the insulated formwork reinforcement structure of the present invention, the vertical reinforcement may have a hanging portion at the upper part that can be hung on the upper edge of the formwork material, and may have a connecting piece portion at the lower part that can be inserted between the formwork material and multiple lower reinforcements. With this configuration, simply by lowering the vertical reinforcement material from above along the insulated formwork, the connecting piece portion of the vertical reinforcement material can be inserted between the formwork material and multiple lower reinforcement materials, and the hanging portion of the vertical reinforcement material can be hung on the insulated formwork, so that multiple vertical reinforcement materials can be easily installed in a removable manner along the insulated formwork. (6) In the insulated formwork reinforcement structure of the present invention, the lower reinforcement member has a main body portion and a connecting piece portion extending downward from the main body portion and inserted between the formwork material and the plurality of lower width stop members, the main body portion is positioned at a position outer in the width direction than the position of the connecting piece portion, and the vertical reinforcement member may have a connecting piece portion inserted between the formwork material and the plurality of lower reinforcement members. With this configuration, first, the connecting piece of the lower reinforcement is inserted between the formwork material and the multiple bottom width stoppers, creating a gap between the main body of the lower reinforcement and the formwork material, and then the connecting piece of the vertical reinforcement can be easily inserted into this gap. Furthermore, since the components are connected by inserting them in this way, they can also be easily removed. (7) In the insulated formwork reinforcement structure of the present invention, the upper part of the vertical reinforcement may be formed with a groove forming portion that forms a groove portion in which the upper reinforcement is placed, and an upper connecting portion that is continuous with the groove forming portion and has a hanging portion that can be hung on the formwork material. With this configuration, the vertical reinforcement can be positioned along the insulated formwork by hanging the hanging portion of the upper connecting portion on the formwork material, and by placing an upper reinforcement in the groove portion of the vertical reinforcement positioned in this manner, the upper reinforcement can be easily and removably connected to the vertical reinforcement. (8) In the insulated formwork reinforcement structure of the present invention, end formwork materials are arranged at the longitudinal ends of a pair of the formwork materials, and among the plurality of bottom width stopper materials, the end bottom width stopper material installed on the longitudinal end side of the pair of formwork materials may have a main body piece portion connecting the pair of formwork materials and a bridging piece portion connecting the main body piece portion and the lower edge of the end formwork material. With this configuration, by using the end lower width stopper material described above, it is possible to prevent the lower edge of the end formwork material from shifting outward, mainly in the longitudinal direction of the insulating formwork. (9) The method for constructing an insulated foundation of the present invention is a method for constructing an insulated foundation in which concrete is poured into an insulated formwork having at least a pair of formwork members, in which a plurality of lower width stoppers are arranged along the longitudinal direction of the formwork members, the pair of formwork members are arranged opposite each other in the width direction and the lower edges of the pair of insulated formworks are connected by a plurality of the lower width stoppers, the upper edges of the pair of formwork members are connected by a plurality of upper width stoppers, and lower reinforcement members extending in a longitudinal direction intersecting the width direction and the vertical direction are arranged in a plurality of front A plurality of vertical reinforcements extending in the vertical direction are connected to the lower width stopper and arranged along the formwork material, and the upper parts of the vertical reinforcements are connected to the formwork material and the lower parts are connected to the lower reinforcement, and the upper reinforcement extending in the longitudinal direction is connected to the upper parts of the plurality of vertical reinforcements to form an insulated formwork reinforcement structure, and the concrete is poured between a pair of the formwork materials and cured, and after the concrete has cured, the upper width stopper, the upper reinforcement, the vertical reinforcement, and the lower reinforcement are removed. According to the foundation construction method of the present invention, by using the above-mentioned lower reinforcement material, the areas between the lower parts of multiple vertical reinforcement materials can be reinforced, and this reinforcement makes it possible to suppress deformation such as outward bulging of the areas of the insulated formwork between the lower parts of multiple vertical reinforcement materials when concrete is poured into the insulated formwork during foundation construction, making it easy to carry out the desired construction. (10) In the insulated foundation construction method of the present invention, the lower reinforcement may have a connecting piece portion that is inserted between the formwork material and the plurality of lower width stoppers, and the connecting piece portion is inserted between the formwork material and the plurality of lower width stoppers to connect to the plurality of lower width stoppers, and the vertical reinforcement may have a connecting piece portion that is inserted between the formwork material and the plurality of lower reinforcements, and the connecting piece portion is inserted between the formwork material and the plurality of lower reinforcements to connect to the plurality of lower reinforcements.
