る。 In recent years, as land prices have increased and buildings have become taller, there has been a desire to effectively utilize site area, reduce construction costs, and ensure work safety. One of the targets for improvement to meet these demands is the conventional concrete pouring method. As shown in Figure 11, the formwork on one side of the concrete wall is erected with shoring and reinforced, and then the other formwork is connected with separators and concrete a is poured. Next, after removing the formwork, anchors b are driven (in some cases, they may be set at the time of reinforcing), and anchors b are angled at predetermined intervals from the wall of the concrete a to adjust unevenness. A material c is provided, and this angle material c
A panel mounting angle material d is attached to the panel, and a decorative panel e constituting the outer wall is attached to the panel mounting angle material d.After that, caulking f is applied to the joint portions of each decorative panel e. In these construction methods,
Even if the outer formwork is set in advance at the very edge of the boundary line with the adjacent land, the outer formwork must be removed after the concrete has hardened, which inevitably creates extra empty space outside the concrete wall, resulting in You will have to sacrifice land area. Therefore, in order to deal with such problems, for example, Japanese Patent Application Laid-Open No. 131252/1983 proposed a method of constructing concrete walls in which the outer formwork and the inner formwork themselves become part of the wall. ing. This involves placing an outer formwork made of concrete with longitudinal ribs and an inner formwork made of synthetic resin with heat insulating material facing each other and connecting them to each other with connecting bolts, etc. In this state, concrete is inserted between the two formworks. After pouring, the formwork can be used as an outer wall and an inner wall without removing it. According to this, the outer formwork that will constitute the outer wall of poured concrete can be used as an outer wall and an inner wall without removing it. Since there is no need to remove it, the site area can be used more effectively, and at the same time,
It is possible to save the time and effort required to remove formwork after pouring concrete. Furthermore, as a technology related to such problems,
For example, there is a construction method for a concrete heat insulating wall body disclosed in Japanese Patent Application Laid-Open No. 57-9939. This is 2
After insulating panels, each consisting of two metal plates filled with heat insulating material, are placed in opposition to each other with a gap between them, and then a spacer is used to maintain a constant gap between the facing panels using grooves pre-formed in the metal plates facing each other. In this method, the insulation panel used as the outer formwork can be used as the outer wall surface of the concrete wall, and the inner wall side can be used as is. Of course, the heat insulating material is also located directly behind the metal plate that makes up the outer wall surface, so excellent heat insulation properties can be obtained.

を目的とする。 However, the conventional construction methods described above have the following problems. In other words, the concrete wall construction method (and the panel structure used therein) described in the former Japanese Patent Application Laid-open No. 58-131252 assumes that precast concrete panels will be used for the outer formwork. Because of this, the wall thickness cannot be made very thin, and the usable interior space will be reduced accordingly. In addition, we use an internal insulation structure in which insulation material is attached to the back of the internal formwork, so if there is a design request to use metal decorative panels on the exterior wall, for example,
Due to the difference in thermal expansion coefficient between concrete and metal, there is a risk of separation between the two or distortion of the outer metal decorative panel, so it cannot be applied as is. On the other hand, in the case of the construction method of the insulation wall body described in the latter Japanese Patent Application Laid-Open No. 57-9939, the outer metal plate of the insulation panel for the outer formwork that forms the outer wall is simply flat with the insulation material inside. Since the panels are only in contact with each other, they tend to separate from each other, and since the sealing structure at the joints between the panels is not sufficient, there is a risk that rainwater etc. may enter from the outside through those parts. In addition, there is a problem in construction that it is very difficult to attach a spacer between the insulation panels for the outer formwork and the inner formwork when they are opposed to each other. In addition to the problems described above, it is necessary to solve the following technical problems in order to form a concrete wall using metal decorative panels that generally constitute the outer wall surface as an outer formwork. In other words, metal decorative panels are usually several millimeters thick, and even if a separator is fixed to them and the formwork on the opposite side is fixed, when concrete is poured and tamped with ramming rods, concrete or ramming may occur. Since the metal decorative panel will be deformed by direct contact with the rod, the structure of the metal decorative panel must be designed to prevent such deformation. In addition, when concrete with a high moisture content during concrete pouring comes into direct contact with metal decorative panels, the panels are likely to corrode, and even after finishing, condensation forms on the inner surface of the metal decorative panels, which have a low specific heat, making them susceptible to rust. Therefore, it is necessary to avoid direct contact between the two. Furthermore, when a metal decorative panel expands or contracts due to heat, the panel will become distorted if there is not enough room to absorb the expansion and contraction. Or you need to reserve space somewhere. In addition, since metal decorative panels configured to a predetermined size are used to facilitate transportation and handling, in order to cast a concrete wall for one floor, a predetermined number of these panels are connected and the joints between the panels are It is necessary to caulk, but in that case, it is necessary to be able to caulk from the inside in order to obtain good sealing properties without degrading the appearance. In this way, if a metal decorative panel for forming an exterior wall surface is actually used as an exterior formwork, various problems must be solved. By solving these problems as much as possible, the present invention provides a metal decorative panel that can actually be used as an external formwork during concrete pouring, and which becomes the external wall material of a concrete wall after pouring. The purpose of this project is to realize a concrete pouring method that involves concrete pouring.

ーが不要となる。 [First invention] According to the concrete pouring method of the first invention of the present application, first, metal decorative panel structures are overlapped and connected to each other in a predetermined state using connecting fittings to form a connecting portion. Since the caulking material is filled from the inside into the caulking material filling space formed by the overlapping part between the two and the frame-shaped ribs along this, the caulking material is sufficiently filled without causing a deterioration in appearance unlike external caulking. A good sealing performance can be ensured, and there is no need to construct scaffolding for caulking work, outer formwork, etc. on the outside of the metal decorative panel structure. After forming the outer formwork with the metal decorative panel structure in this way, one end of the separator is connected to the inner formwork installed to face this, and the other end is connected to the intermediate part of the connecting fitting. Since both the inner and outer formwork are connected and fixed by screwing together, the work of installing the separator can be easily performed. In addition, since there is no need to attach angle materials for adjusting the unevenness of the outer surface of the concrete wall or other angle materials to connect this and metal decorative panels, as in the past, metal The width to the outer surface of the decorative panel can be greatly reduced, and the external dimensions of the building can be reduced accordingly, or a relatively large indoor space can be secured. Since concrete is poured between both formworks with both formworks installed in this way, the separator, which is originally a means of determining the concrete wall thickness, is used to place the metal decorative panel structure on the wall. It also functions as an anchor for fixation. This eliminates the need to separately set the separators and anchors, and the number of steps can be reduced accordingly. [Second Invention] Further, according to the metal decorative panel structure that also serves as a formwork according to the second invention of the present application, two sides adjacent to each other are formed to have approximately half the thickness over a predetermined width, and the other two sides are Since the thickness is approximately half that across a predetermined width on the side opposite to the side, when this decorative panel structure is connected to each other as a unit, one of the two sides is turned outward and the other two sides are By overlapping each other with the sides facing inside, it is possible to avoid a change in thickness at the connecting portion. In addition, since frame-like ribs and lattice-like ribs are provided on the back side of the metal decorative panel structure, and a heat insulating material is provided in the area surrounded by both ribs, the metal decorative panel structure can be transformed into a simple flat metal decorative panel. Moreover, since the concrete is not in direct contact with the metal decorative panel structure, it is possible to prevent the metal decorative panel structure from deforming due to the pressure of the poured concrete when compacted. . Further, both ends of the connecting fitting are attached across the rib portion of the frame-like rib located on the outside of the inner overlapping portion of one panel structure and the outer overlapping portion of the other panel structure stacked thereon. Since one end of the separator is screwed into the middle part of the metal fitting, even if the metal decorative panel expands or contracts due to heat, the expansion and contraction will cause a connection between the heat insulating material and the separator. By being absorbed by the metal fittings, deformation of the panel due to the difference in thermal expansion between the metal decorative panel and the concrete is prevented. In addition, as mentioned above, since a heat insulating material is provided in the area surrounded by the frame-like ribs and lattice-like ribs formed on the back side of the metal decorative panel, concrete is directly applied to the metal decorative panel during concrete pouring. Corrosion of the panels is prevented because they cannot be touched, and after the concrete wall is formed, an external insulation structure is created in which the insulation material is located directly behind the exterior wall surface (metallic decorative panels), so internal insulation can be prevented. This results in a better thermal insulation effect than in the case of a structural structure. In addition, according to this metal decorative panel structure, since the separator is screwed into the middle part of the connecting fittings that connect them to each other, it can be used as an outer formwork when pouring concrete. In this case, there is no need for angle materials or fixing anchors to attach the metal decorative panel to the concrete wall.

のサイズに限定されるものではない。 Hereinafter, embodiments of the first invention and the second invention of the present application will be described based on FIGS. 1 to 10. First, a metal decorative panel structure serving as a formwork according to the second invention will be explained. As shown in FIGS. 1 to 6, this metal decorative panel structure 1 has an inner overlapping portion 2a formed by forming two adjacent side edges to approximately half the thickness over a predetermined width. It has a metal decorative panel 2 for outer surface construction, in which two sides thereof are formed as an outer overlapping part 2b formed to have a thickness approximately half over a predetermined width on the side opposite to the two sides. On the back side of this metal decorative panel 2, there is a frame-shaped rib 3 that protrudes along each of the overlapping parts 2a, 2b so as to be located inside the panel in the vicinity thereof, and within the frame of this frame-shaped rib 3. The lattice-like ribs 4 formed in Corresponding first rib portion 3
elongated holes 6...6 formed in the longitudinal direction of a, and a second rib portion 3b corresponding to the other inner overlapping portion 2a.
bar-shaped fitting protrusions 7...7 protruding from the outer surface of the frame and having a diameter that can be fitted into the elongated holes 6...6; metal fittings mounting bolts 8...8 are provided. When the outer overlapping portions 2b and the inner overlapping portions 2a of the metal decorative panels 1, 1 adjacent to each other are superposed to arrange a plurality of metal decorative panel structures 1 in parallel in a predetermined state, the overlapping portions are The first rib portion 3a on the outer overlapping portion 2b side and the inner overlapping portion 2a in
A space A for filling caulking material is formed between the side second rib portion 3b. Also,
Both ends 10b, 10 of a connecting fitting 10 in which one end of a rod-shaped separator 9 can be screwed into an intermediate part 10a.
b is configured to be fastened to a metal fitting mounting bolt 8 using a nut across the space A and both rib portions 3a and 3b. Here, the metal decorative panel 2 is approximately 1.8m x 0.6m.
Although Corten steel with a thickness of 3.2 mm was used, stainless steel, aluminum alloy, or any other suitable material that can be generally used as a decorative panel may be used. The frame-like ribs 3 and the lattice-like ribs 4 are fixed to the metal decorative panel 2 by welding Cor-ten steel plates of about 30 mm. The heat insulating material 5 is made of urethane foam and is attached to fill the space formed by the frame ribs 3 and the lattice ribs 4, but it may also be used for other heat insulating effects or as a filler. Any suitable material can be used as long as it fulfills the role of. The connecting fitting 10 is constructed by bending a metal plate, and is connected to the decorative panel structure 1 on one side and to the separator 9 on the other side by bolts 8 and nuts. The widths of the inner overlapping portion 2a and the outer overlapping portion 2b of the metal decorative panel 2 are approximately 15 mm. Further, a fitting protrusion 7 provided on the frame-shaped rib 3
is fitted into the long hole 6 similarly provided in the rib 3 when connecting the metal decorative panel structures to each other. Although a silicone resin-based caulking material 12 is used, other commonly used caulking materials may be used. Reference numeral 13 in the figure is a rubber gasket,
It is located at the end of the overlapping side edges of the metal decorative panels 2, and serves to facilitate the alignment of both panels 2. Further, reference numeral 10' denotes a metal fitting attached to the lattice-like rib and connected to one end of the separator 9.
According to the above configuration, two adjacent sides of the metal decorative panel structure 1 that also serves as a formwork are formed to have a predetermined width and approximately half the thickness, and the other two sides are formed with a predetermined thickness on the side opposite to the two sides. This decorative panel structure 1 is formed with approximately half the thickness across the width.
When interconnecting the two sides as a unit, by overlapping each other with the outer overlapping parts 2b located on one of the two sides on the outside and the inner overlapping parts 2a located on the other two sides on the inside, the overlapping parts can be connected to each other as a unit. It is possible to avoid changes in the thickness at (a). In addition, the frame-like ribs 3 and the lattice-like ribs 4 are provided on the back side of the metal decorative panel structure 1, and the heat insulating material 5 is provided in the area surrounded by both ribs, so that the metal decorative panel structure 1 has a simple flat plate-like shape. The metal decorative panel structure 1 has a stronger structure than the metal decorative panel, and since the concrete does not come into direct contact with the panel surface of the metal decorative panel structure 1 when concrete is poured, the metal decorative panel structure 1 is able to compact the poured concrete. It is possible to prevent deformation due to the pressure of time. Furthermore, the inner overlapping portion 2a of one panel structure 1
and the outer overlapping portion 2b of the other panel structure 1 overlaid thereon, and the rib portions 3b, 3a of the frame-like rib 3 located on the outer side. The middle part 10 of the metal fitting 10 is attached to the bolts 8, 8 of 2.
Since one end of the separator 9 is screwed into the connecting fitting a, even if the metal decorative panel 2 expands or contracts due to heat, the expansion and contraction will be connected to the heat insulating material 5 and the separator 9. 10, panel deformation due to the difference in thermal expansion between the metal decorative panel 2 and the concrete is prevented. In addition, since the heat insulating material 5 is provided in the area surrounded by the frame-like ribs 3 and the lattice-like ribs 4 formed on the back surface of the metal decorative panel 2 as described above, concrete can be directly Corrosion of the panel is prevented because the metal decorative panel 2 is not touched, and after the concrete wall is formed, an external insulation structure is created in which the heat insulating material is located directly behind the external wall surface (metal decorative panel). Therefore, a better insulation effect can be obtained than in the case of an internal insulation structure. Moreover, according to this metal decorative panel structure 1,
Since the separator 9 is screwed into the intermediate part 10a of the connecting fitting 10 that connects them to each other, when used as an outer formwork during concrete pouring, metal can be attached to the concrete wall. There is no need for angle materials or fixing anchors for attaching decorative panels. Next, a concrete pouring method according to the second invention of the present application using the metal decorative panel structure described above will be explained. First, the metal decorative panel structures 1 are arranged in parallel so that the outer overlapping part 2b of one metal decorative panel 2 and the inner overlapping part 2a of the other metal decorative panel 2 overlap, and Space A for filling caulking material between the first rib portion 3a on the overlapping portion 2b side and the second rib portion 3b on the inner overlapping portion 2a side
is formed, one end of the separator 9 can be screwed into the intermediate portion 10a, and both ends 10b, 10b of the connecting fitting 10 are connected to the space A and both rib portions 3.
A and 3b are connected to each other by straddling them and fastening them to metal fitting mounting bolts 8. Next, in this state, these decorative panel structures 1
...1 is installed as an outer formwork constituting the outside of the concrete wall body B, and then the caulking material 12 is inserted from the inside into the caulking material filling space A located on the back side of the mutually overlapping part A of each decorative panel structure. After that, the inner formwork (not shown) that constitutes the inside of the concrete wall body B to be cast is installed with shoring so as to face these decorative panel structures 1...1. , one end of the separator is connected to this inner mold, and the other end is connected to the intermediate part 10a of the connecting fitting 10.
By screwing into the inner formwork sections, the decorative panel structures 1...1 are connected and fixed. Then, in this state, concrete is poured between the inner formwork and the decorative panel structures 1...1, so that the separator 9 also serves as an anchor for the concrete wall B of the decorative panel structure 1. According to such a configuration, first, the metal decorative panel structures 1...1 are overlapped and connected to each other in a predetermined state using the respective connecting fittings 10, and the overlapping portion of the metal decorative panel structures forming the connection portion is formed. Since the space A for filling the caulking material formed by the frame-shaped ribs 3 along this space is filled with the caulking material 12 from the inside, the appearance will not be as bad as when caulking is performed from the outside. Sufficient sealing performance can be ensured without causing any damage, and there is no need to construct scaffolding for caulking work, outer formwork, etc. on the outside of the metal decorative panel structures 1...1. After forming the outer formwork with the metal decorative panel structures 1...1 in this way, one end of the separator 9 is connected to the inner formwork installed to face this, and the other end is connected to each of the above-mentioned connections. Since both the inner and outer formworks are connected and fixed by screwing into the intermediate portion 10a of the metal fitting 10, the separator 9 can be easily attached. In addition, since there is no need to attach angle materials for adjusting the unevenness of the outer surface of the concrete wall B or other angle materials to connect this and the metal decorative panel as in the past, the outer surface of the concrete wall B The width from the to the outer surface of the metal decorative panel 2 can be greatly reduced, and the external dimensions of the building can be reduced by that much, or a relatively large indoor space can be secured. Since concrete is cast between both formworks with both formworks installed in this way, the separator 9, which is originally a means of determining the concrete wall thickness, is attached to the wall B with a metal decorative panel structure. It also functions as an anchor for fixing the body 1. This eliminates the need to separately set the separator and anchor, and the number of steps can be reduced accordingly. According to the size of each member described in the above embodiment, the size is reduced by about 4 to 5 cm compared to the conventional size, so that a space of about 10 cm can be effectively used as the building's side walls. Each member of the present invention is not limited to the size of the above embodiment.

ーが不要となる。 As described above, according to the concrete pouring method of the first invention of the present application, it is possible to ensure sufficient sealing performance without causing deterioration in appearance unlike when caulking is applied from the outside. There is no need to construct scaffolding for caulking work, external formwork, etc. on the outside of the metal decorative panel structure. In addition, since there is no need to attach angle materials for adjusting the unevenness of the outer surface of the concrete wall or other angle materials to connect this and metal decorative panels, as in the past, metal The width to the outer surface of the decorative panel can be greatly reduced, and the external dimensions of the building can be reduced accordingly, or a relatively large indoor space can be secured. Furthermore, since the separator, which is originally a means of determining the concrete wall thickness, also functions as an anchor for fixing the metal decorative panel structure to the wall, it is possible to save the trouble of separately setting the separator and anchor. The number of steps can be reduced accordingly. [Second Invention] Further, according to the metal decorative panel structure that also serves as a formwork according to the second invention of the present application, two sides adjacent to each other are formed to have approximately half the thickness over a predetermined width, and the other two sides are Since the thickness is approximately half that across a predetermined width on the side opposite to the side, when this decorative panel structure is connected to each other as a unit, one of the two sides is turned outward and the other two sides are By overlapping each other with the sides facing inside, it is possible to avoid a change in thickness at the connecting portion, and therefore, it is possible to avoid deterioration in appearance. In addition, by providing frame-like ribs and lattice-like ribs on the side of the metal decorative panel structure, and installing a heat insulating material in the area surrounded by both ribs, it is possible to make the metal decorative panel structure look like a simple flat metal decorative panel. To prevent the metal decorative panel structure from deforming due to pressure during compaction of poured concrete, since the structure is stronger than that of a panel and the concrete does not come into direct contact with the metal decorative panel structure. I can do it. Further, both ends of the connecting fitting are attached across the rib portion of the frame-like rib located on the outside of the inner overlapping portion of one panel structure and the outer overlapping portion of the other panel structure stacked thereon. One end of the separator is screwed into the middle part of the metal fitting, so even if the metal decorative panel expands or contracts due to heat, the expansion and contraction will connect to the heat insulating material and the separator. By being absorbed by the connecting fittings, deformation of the panel due to the difference in thermal expansion between the metal decorative panel and the concrete is prevented. In addition, as mentioned above, since a heat insulating material is provided in the area surrounded by the frame-shaped ribs and lattice-shaped ribs formed on the back side of the metal decorative panel, concrete is directly applied to the metal decorative panel during concrete pouring. Corrosion of the panels is prevented because they cannot be touched, and after the concrete wall is formed, an external insulation structure is created in which the insulation material is located directly behind the exterior wall surface (metallic decorative panels), so internal insulation can be prevented. This results in a better thermal insulation effect than in the case of a structural structure. In addition, according to this metal decorative panel structure, since the separator is screwed into the middle part of the connecting fittings that connect the panels, it can be used as an outer formwork when pouring concrete. In this case, there is no need for angle materials or fixing anchors to attach the metal decorative panel to the concrete wall.
