Description

[Technical Field]

[0001] The present invention relates to a wall-type construction (WRC) in which a building is supported by walls (load-bearing walls, structural walls) made of reinforced concrete (RC), which allows for effective use of land, is applicable to narrow lots without damaging the living environment of the surrounding area, and can easily construct high-strength buildings using formwork panels that can also be used as exterior materials. [Background technology]

[0002] Reinforced concrete (RC) buildings have a rigid frame structure, in which columns and beams made of rebar or steel frames support the building, and are applied to large-scale structures and buildings. This has the advantage of allowing buildings to be tall, but requires work space (including scaffolding) for constructing and removing formwork, and for exterior wall construction, which is undesirable from the perspective of effective land utilization and damaging the living environment of neighboring areas. In addition, this type of building has a structure in which columns and beams protrude from the interior surfaces, and requires scaffolding to be installed on the perimeter, which means it is not suitable for narrow spaces such as urban areas.

[0003] In contrast, wall-mounted construction (WRC), which supports buildings with walls (load-bearing walls, structural walls), does not require scaffolding around the building, allowing for more interior space to be used and construction to fill the entire site (i.e., ideal for small lots). While a known construction method for this type of wall structure involves bringing precast walls to the site and constructing them, the most common construction method involves constructing the walls on site by pouring concrete using spacing members, which are rod-shaped members that are straight when viewed from the side. DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0004] However, various conditions (restrictions) make it difficult to use this wall structure in high-rise buildings. Therefore, the applicant has considered a structure that can effectively utilize the site area on a narrow lot by using a formwork that can also be used for exterior materials, without removing the outer formwork. In particular, he has placed importance on incorporating it into a rigid frame structure, which is necessary for high-rise buildings.

[0005] Therefore, the present invention aims to propose a construction method for installing formwork panels that can also be used as exterior materials, which allows for effective use of land, does not harm the living environment of the surrounding area, can be applied to small lots, and allows for the easy construction of high-strength buildings. [Means for solving the problem]

[0006] The present invention has been proposed in consideration of the above, and relates to an outer panel installation structure in which a formwork panel that can also be used as exterior material (hereinafter referred to as the outer panel) and an inner formwork have multiple spacing members arranged in the opposing direction at the opposing gap between them, wherein the spacing members include a first member that can be assembled to the outer panel and a second member that can be assembled to the inner formwork, and is constructed using straight members that directly connect the first member and the second member, and folded members that connect the first member to the second member and / or reinforcing bars via orthogonal connecting members.

[0007] The present invention also proposes a structure for installing a formwork panel that can also be used as exterior material, characterized in that in the above-mentioned installation structure, the connecting material is integrated with the first member by being engaged or fastened.

[0008] The present invention also proposes a structure for installing a formwork panel that can also be used as an exterior material, characterized in that in the above-mentioned installation structure, the connecting member is rotatably connected to the first member.

[0009] The present invention also proposes an outer panel fitting structure, characterized in that the connecting material is installed between a plurality of the spacing members. [Effects of the Invention]

[0010] The present invention constructs an outer wall using outer panels made by laminating an inner layer material (insulating material) on the back side of an exterior material, and the spacing members are constructed using straight members, which are conventional linear members, and folded members with orthogonal connecting members interposed between them.Depending on the building to be constructed and its wall structure, two types of forms can be appropriately selected and applied to various buildings and their wall structures. Therefore, for example, in wall structures or buildings where reinforcing bars are arranged inside, folded materials can be selected and arranged in areas where straight materials cannot be arranged due to interference from the reinforcing bars, which increases the strength to withstand the increased concrete pouring pressure that comes with high-rise buildings, and makes it possible to effectively utilize the site area on narrow lots. In other words, even in wall-type structures that are weaker than rigid frame structures, by applying reinforcing bars and this invention appropriately, the height limit for buildings can be extended (expanded) from the conventional level, and they can be made taller. Furthermore, the built-in structure of the present invention does not require scaffolding around the building, which allows for efficient use of land, does not harm the living environment of the surrounding area, and can be applied to small lots. Moreover, after construction, the outer panels can be used as exterior or interior materials.

[0011] Furthermore, in the above-mentioned erection structure, if the connecting member is integrated with the first member by locking or fastening, the first member of the folded member can be integrated with the connecting member before installation. This eliminates the need to attach the connecting member during construction, improving workability on site.

[0012] Furthermore, in the erection structure, when the connecting material is rotatably connected to the first member, the work of connecting the second member in the folded member and the work of connecting it to the reinforcing bar become easier.

[0013] In addition, in the above-mentioned erection structure, when the connecting members are installed between the plurality of spacing members, this corresponds to, for example, a configuration using a long connecting member, and the connecting members may be installed in an erected state between the plurality of first members, and the plurality of second members may be installed in an erected state between the connecting members. This makes it easy to install the connecting members and connect them to the second members. Furthermore, in this case, the opposing distance between the outer panel and the inner formwork can be more firmly maintained. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0015] The outer panel installation structure of the present invention is a structure in which a plurality of spacing members are arranged in the opposing direction at the space between the outer panel and the inner formwork, and the spacing members include a first member that can be assembled to the exterior material / formwork panel and a second member whose tip protrudes from the inner formwork, and is constructed using a straight member that directly connects the first member and the second member, and a folded member that connects the first member to the second member via an orthogonal connecting member.

[0016] The outer panel used in the present invention has a structure in which an exterior material is used on the outermost side (surface side) and an inner layer material is laminated on the back side thereof. There are no restrictions on the material of the exterior material, as long as it has fixing parts to which the ends of the spacing members that connect the outer panel and the inner formwork can be attached. The inner layer material is mainly assumed to be various types of heat insulating material, but there are no restrictions on the material or thickness as long as it has the strength to withstand concrete pouring. Such outer panels can also be applied to exterior materials (extruded materials) that are configured in a manner similar to the formwork-cum-decorative panels that the applicant has previously considered, in which two types of decorative materials are alternately connected, one with a fixing portion on one side (one side end) and the other without, and the ends of spacing members (separators) can be attached to the fixing portions, and a width of approximately 150 mm is generally (practical) and multiple sheets of exterior materials can be attached to one side of an inner layer material (insulating material) that is usually molded to a width of nearly 600 mm, and can be used as an outer panel.

[0017] The anchoring portion formed on the exterior material is a portion for fixing the end of a spacing member for securing a space for pouring concrete. The materials and molding methods for the exterior cladding are not particularly limited, and various materials can be used for the surface materials, including metal surface materials, hard resin plates, and extruded materials such as aluminum. Multiple types of exterior cladding materials can be connected together, and as in the illustrated examples described below, exterior cladding materials with anchoring sections can be combined with exterior cladding materials without anchoring sections. While the thickness is not particularly limited, it is preferable for the thickness to be at least 1.2 to 1.6 mm, and for the surface to be strong enough to withstand slight stresses such as concrete pouring pressure.

[0018] The inner layer material (insulating material) can be made of any material as long as it does not burst under the pouring pressure of concrete, as described above, and may be a single layer, a laminate of two or more insulating materials with different properties, or a material that uses a separate reinforcing material, etc. For example, it may be any type of synthetic resin foam that requires a certain thickness, or inorganic materials such as gypsum board, PC panel, ALC panel, or other fireproof or fire-resistant material, and may be configured to be pre-integrated with one side (one side) of the exterior material, or may be prepared separately.

[0019] To explain in more detail the fixing portion provided on the back side of the exterior material, it is sufficient that it can connect the end of the spacing member. For example, if the end of the spacing member is a male threaded portion, the fixing portion can be made by integrating various types of square nuts or a plate-shaped material with multiple female threaded portions, or the piece to be overlapped can be made thick and tapped (female threaded). In particular, a space that is open on the side or back side may be provided on the back side of the face plate, and a square nut or the like having a threaded portion may be attached to form the fastening portion. When a general-purpose nut is used, the square head of the square nut prevents co-rotation (self-rotation) when the spacing member is attached. It is desirable to insert a buffer material in this space to prevent contact between the square nut or the like and the exterior material. This buffer material may be the same material as the inner layer material (insulating material) or an elastic material such as rubber.

[0020] As described above, the spacing member (separator) is a member whose end is attached to the fixing portion formed in the exterior material. Conventionally, spacing members that have been used are rod-shaped members that are straight when viewed from the side, and consist of a first member to which the exterior material and inner layer material can be assembled, and a second member whose tip protrudes from the inner formwork. These first and second members can be freely connected / separated by tightening, and the opposing gap (opposing space) between the outer panel and the inner formwork is the space into which concrete is poured. As mentioned above, it has been known that the spacing member used conventionally is a linear material in side view, which allows the first member and the second member to be freely connected / separated by tightening, but the spacing member of the present invention uses a straight material equivalent to the linear material and a folded material in which a connecting member is connected between the first member and the second member.

[0021] The connecting material is connected (coupled) between the first and second members of the folded material, and is a member shaped like a short plate, a strip, an L-shape, a Z-shape, a C-shape, etc., and may be appropriately selected from steel materials or high-strength resin materials having the strength required at the installation location. In addition, the first member, connecting member, and second member may be fastened directly mainly by the male and female thread portions, or fastened in a clamping manner by the male and female threads, and the female thread portion may have a nut or the like fixed thereto or may be formed by tapping. The shape and length of this connecting material are not limited, but by rotating (rotating or swiveling while maintaining a perpendicular position) like the piece-shaped connecting material in Example 1 described below, it is possible to avoid (rotate to a location where it will not interfere with) the reinforcing bars arranged around it. Furthermore, multiple holes may be formed along the length, as in the long connecting material of Example 2. These holes may be circular or oval holes, as they are used to fasten the first member or the second member. For example, when multiple holes are formed, as in the long connecting material of Example 2 described below, multiple first members may be attached in a bridging manner, or multiple second members may be attached in a bridging manner.

[0022] The reinforcing bars arranged in the facing space (concrete pouring space) formed by multiple spacing members may be individual reinforcing bars, or may refer to reinforcing bar columns (columnar reinforcing bars) of a rigid frame structure made up of multiple reinforcing bar bundles. In other words, this reinforcing bar includes reinforcing bars that form the walls of a wall-type construction (WRC) and columnar reinforcing bars of a rigid frame structure. The method (structure) of connecting the connecting material to the reinforcing bar may be, for example, by connecting with a strong strip material (which may be provided with bending or fastening parts as necessary), or by spot welding.

[0023] Furthermore, since the outer panel is formed by laminating an inner layer material (insulating material) on the back side of the exterior material, it is possible to form the exterior surface portion with multiple exterior materials and form the insulating layer with one inner layer material, for example as in the illustrated example described below, and the insulating layer side can be used as a space for pouring concrete, and after construction it is possible to construct a concrete building with the exterior material arranged on its surface.

[0024] In this way, the present invention uses straight members that do not use connecting members and folded members that use connecting members as spacing members that form the opposing gap between the outer panel and the inner formwork, so folded members can be placed in places where straight members cannot be placed, and the outer formwork / exterior material and the inner formwork can be connected without affecting the position or quantity of rebar, allowing for stable erection of the formwork (outer panel).In particular, since it can be used in places with a large amount of rebar in rigid frame structures, using the outer panel allows for maximum use of the site area (no space is required for formwork installation), and coupled with the construction of high-rise buildings, it allows for effective use of land. Furthermore, because the outer wall is constructed from outer panels made by laminating an inner layer (insulation material) on the back side of the exterior material, in principle no scaffolding is required around the area, which allows for effective use of land, does not harm the living environment of the surrounding area, and can be applied to small lots. Moreover, after construction, the outer panels can be used as exterior or inner layer materials as they are. [Example]

[0025] 1(a) and (b), the erection structure of the exterior material / formwork panel (outer panel) 1 of Example 1 is a structure in which a plurality of spacing members 2 are arranged in the opposing direction at the opposing interval between the outer panel 1 and an inner formwork (not shown), and the spacing members 2 are selectively used from among a first member 2A that can be assembled to the outer panel 1 and a straight member 2I that directly connects a second member 2B whose tip protrudes from the inner formwork, and a folded member 2II that connects the first member 2A and the second member 2B via an orthogonal connecting member 3 (piece-shaped connecting member 3A). That is, in Example 1, a plurality of reinforcing bars 4 are arranged in the opposing interval, and folded members 2II are arranged in places where the reinforcing bars 4 cannot be arranged with only the straight member 2I due to interference. In this first embodiment, the outer panel 1 and the straight members 2I will be described below with reference to FIG. 3, and the reinforcing bar columns (reinforcing bar columns) 4A as the reinforcing bars 4 with reference to FIG.

[0026] The piece-shaped connecting material 3A used in this Example 1 is a plate-like material with two circular holes 30, 30 formed side by side as shown in Figure 1(c), and the end of the mounting bolt 9A is inserted and fastened into one of the circular holes 30 (the upper side in the folded material 2II shown in Figure 1(b)), and a nut 9B is fixed to the other circular hole 30. Therefore, this piece-like connecting material 3A can be attached to the first member 2A by fastening the mounting bolt 9A, and the second member 2B can be attached by fastening the fixed nut 9B. Note that a plate material 3a having the same thickness as the piece-like connecting material 3A is interposed between the first member 2A and the second member 2B of the straight member 2I. In the illustrated embodiment, the second member 2B is connected by avoiding (rotating to a position where it does not interfere with) the installed reinforcing bars 4. This rotation refers to a direction that avoids (a position where it does not interfere with) the vertical reinforcing bars 4 or the horizontal reinforcing bars (not shown), and the avoidance can be rotated 360 degrees around the end of the first member 2A.

[0027] 2(a) and 2(b) show different modes of connecting the second member 2B to the piece-shaped connecting material 3A. A nut 9B is fixed to the lower circular hole 30 of the piece-shaped connecting material 3A in Figure 2(a), and the second member 2B can be attached by tightening the nut 9B, similar to Figure 1(b) above, but the first member 2A is inserted into the upper circular hole 30 so that it can rotate (swivel, slide). Similarly, the first member 2A is inserted into the upper circular hole 30 of the piece-shaped connecting material 3A' in Figure 2(b) so that it can rotate (swivel, slide), but the lower circular hole is internally threaded, so it is designated by the symbol 30'', and the second member 2B can be attached by fastening it to the internally threaded hole 30''.

[0028] Figures 2(c) and (d) show the effectiveness of the U-shaped connecting member 3C. The U-shaped connecting material 3C shown in the figure consists of opposing rectangular plate materials 34, 34' and a rod material 35 connecting them, and one of the plate materials 34 has a circular hole 30 through which the first member 2A can rotate (swivel, slide) as in the piece-shaped connecting material 3A', and a circular hole 30" with an internal thread, and the other plate material 34' has circular holes 30", 30" with internal threads formed side by side. By using this U-shaped connecting material 3C, the first member 2A and the second member 2B can be arranged in a straight line in a divided shape, so that the core part of the spacing member 3 can be made the same as the straight member 2I, which makes the positioning as a spacing member stable and improves workability. The U-shaped connecting material 3C can also be arranged to enclose a reinforcing bar 4 (not shown) from the side.

[0029] As shown in Figure 3(a), the outer panel 1 consists of an exterior surface portion in which two types of exterior materials 1A and 1B are alternately connected, and an insulating layer formed of an inner layer material (insulating material) 5 shown in Figure 3(c) arranged on the back side of the exterior surface portion. As shown in Figure 3(b), the exterior surface portion is made up of exterior material 1A having a space 14 on the back side of face plate portion 11, which is the finished surface, and exterior material 1B having no space 14, and each face plate portion 11 has a protrusion 111 that protrudes toward the front side in a roughly T-shape at the approximate center of the face plate portion 11. Of these, exterior material 1A having space 14 has engaging portions 12a, 12c provided at its edge, and exterior material 1B having no space 14 is an extruded aluminum member having engaging receiving portions 12b, 12d provided at its edge. The engaging portions 12a and 12c are provided on their surfaces with ridges having the same shape as the ridges 111.

[0030] As described above, the outer panel 1 is made up of the exterior materials 1A, 1B and the insulating material 5, and is formed by stacking two sheets of each of the two types of exterior materials 1A, 1B alternately on the surface side of one insulating material 5, so that the outer panel 1 is connected in the width direction. The holes indicated by dashed lines 50 in the drawing of the heat insulating material 5 indicate the positions where the spacing members 2 (first members 2A) are disposed. Then, engaging portion 12a of exterior packaging material 1A and engaging receiving portion 12d of exterior packaging material 1B are assembled in an engaging state, forming a molded portion having a substantially U-shaped space portion 14, and engaging receiving portion 12b of exterior packaging material 1A and engaging portion 12c of exterior packaging material 1B are assembled in an engaging state. Note that space portion 14 contains a fixing material such as a nut or a cushioning material to form a fixing portion.

[0031] As shown in Fig. 3(c), the left and right edges of the heat insulating material 5 are cut out, one from the front side and the other from the back side, so that they can be overlapped in a jut-like manner, with the edge facing the overlapping state being the overlapping portion 52a and the other end side overlapping with the overlapping portion 52a being the non-overlapping portion 52b. In addition, a recess 51 is formed in the approximate center, into which the space portion 14 of the packaging material 1A is fitted.

[0032] In general areas where reinforcing bars do not interfere, the spacing member 2 (straight member 2I) uses a straight member 2I that is a rod-shaped member that is straight when viewed from the side, as shown in Figure 3(d).The spacing member (straight member 2I) shown in the figure is a first member 2A to which the exterior materials 1A, 1B and the inner layer material (insulating material) 5 can be assembled, and a second member 2B whose tip protrudes from the inner formwork 6, which are linearly connected (directly joined), and the opposing gap (opposing space) between the outer panel 1 and the inner formwork 6 is used as the space into which concrete is poured. The tip of the first member 2A is an end (anchoring portion) that leads to the space 14 of the exterior packaging material 1A, and a fixing portion is also provided at the other end. The tip of the second member 2B is a male thread portion that screws into the other end (female thread portion) of the first member 2A, and the other end is provided with a contact portion that is tightened by tightening means from further outside the inner formwork 6 and is pressed against the inner formwork 6.

[0033] FIG. 4 shows an example in which reinforcing bar columns (reinforcing bar columns) 4A made of a plurality of reinforcing bar bundles are installed at the corners of a foundation 7. Unlike the reinforcing bars 4 used in Figure 1(a) above, which are each arranged individually, these steel columns 4A are placed in the corners of the interior space, and unlike the construction of a general rigid frame structure, they do not use long vertical bars, but rather vertical bars of a specified length are connected in the vertical direction and used as vertical bars without setting up scaffolding around them.

[0034] In Fig. 4(a), a plurality of vertical reinforcement bars 4a are arranged and fixed in a rectangular shape in a plan view at the corners of the foundation 7. Note that the reference numeral 4b shown in the figure denotes a band-like reinforcement bar that surrounds the plurality of vertical reinforcement bars 4a. In Fig. 4(b), the plurality of vertical reinforcements 4a and strip-shaped reinforcing bars 4b are surrounded in an L-shape by two outer panels 1, 1. In this state, the outer panel 1 does not have a spacing member 2 disposed thereon, so it is in the state shown in Fig. 2(a). 4(c) shows a state in which the first member 2A of the spacing member 2 is attached from the inside to each of the outer panels 1, 1. A male thread is provided at the tip of the first member 2A and reaches the space 14 of the exterior material 1A, so that it screws into a female thread provided in the space, and the other end provided with the female thread protrudes. FIG. 4(d) shows a state in which vertical reinforcements 4a are connected to vertical reinforcements 4c of a predetermined height, thereby extending them higher upward. FIG. 4(e) shows a state in which a plurality of vertical reinforcements 4c are surrounded by strip-shaped reinforcement bars 4b at a plurality of positions in the height direction, forming a rectangular pillar-shaped reinforcement bundle (columnar reinforcement bars 4A). Furthermore, Figure 4(e) does not show the L-shaped reinforcing material 7B shown in Figures 4(b) to (d), but does show the piece-shaped connecting materials 3A, 3A used in Figure 1(a).

[0035] As shown in Figures 4(b) to 4(d), planar reinforcement members 8A and L-shaped reinforcement members 8B are disposed on the inside of the two outer panels 1, 1 that form the corners. These planar reinforcement members 8A and L-shaped reinforcement members 8B are high-strength planar reinforcement members and L-shaped reinforcement members, respectively, which are formed into an L-shape in a plan view and are used as reinforcement members with even higher strength. Furthermore, while a space is formed inside the rectangular column-shaped reinforcing bar 4A that will ultimately be installed as shown in Figure 4(e), a lightweight filler material may be placed in the space, or various columnar materials may be placed in the space.

[0036] The outer panel 1 erection structure of Example 1 having such a configuration constructs an outer wall using the outer panel 1 formed by laminating an inner layer material (insulating material) 5 on the back side of the exterior materials 1A and 1B, and the spacing retaining members 2 include straight members 2I and folded members 2II. In areas where the straight members 2I cannot be placed due to interference from the reinforcing bars 4, folded members 2II can be selected and placed, so the outer panel 1 and the inner formwork can be connected without affecting the position or quantity of the reinforcing bars, allowing for stable erection of the formwork (outer panel 1). Since the outer panel 1 can be used in areas with a large amount of reinforcing bars, in particular in rigid frame structures, the use of the outer panel 1 allows for maximum use of the site area (no space is required for formwork installation), and coupled with the construction of high-rise buildings, it allows for effective use of land. Furthermore, this built-in structure does not require scaffolding around the building in principle, which allows for effective use of land, does not harm the living environment of the surrounding area, and can be applied to small lots. Moreover, after construction, the outer panel 1 can be used as it is as exterior materials 1A, 1B or inner layer material 5.

[0037] To briefly explain the construction procedure for this erection structure, the outer panel 1 is placed on the outside, and reinforcing bars 4 are extended vertically in the internal space. After that, the first member 2A of the spacing member 2 is attached from the inside toward the outer panel 1, and piece-shaped connecting materials 3A are fastened (fixed) to the end of the first member 2A as folded members 2II. The attachment to this piece-shaped connecting material 3A is as shown in Figures 1(b) and 2(a) above, where a nut 9B is fixed to the circular hole 30 below the piece-shaped connecting material 3A, and the second member 2B can be attached by tightening the nut 9B. Furthermore, the first member 2A is inserted into the upper circular hole 30 of the piece-shaped connecting material 3A' so as to be able to rotate (swivel, slide), while the second member 2B can be fastened to the lower circular hole 30'', which is provided with an internal thread. The first member 2A is attached to the outer panel 1 by screwing (barely attaching) a male screw portion provided at the tip of the first member 2A into a female screw portion formed in the space portion . This second member 2B is double-tube shaped, and a fastening member (not shown) such as a Form Tie (registered trademark) or a thick horizontal end member that extends to the outside of the inner formwork 6 is connected to its rear end, so that the second member 2B can be connected by operating it from the outside of the inner formwork 6 (fastening work). Concrete is poured into the gap between the formed outer panel 1 and the inner formwork 6, and after curing (hardening), the inner formwork 6 and fastening members are removed and reused, while the outer cylindrical body forming the second member 2B is buried in concrete. [Example]

[0038] The erection structure of the outer panel 1 of Example 2 shown in Figures 5(a) and (b) is similar to that of Example 1 described above in that a plurality of spacing members 2 are arranged in the opposing direction at the space between the outer panel 1 and an inner formwork 6 (not shown). However, it differs from Example 1 described above in that a connecting member 3B, which is a long connecting member, is installed between a plurality of spacing members 2, 2 (first members 2A, 2A).

[0039] The connecting material 3 (long connecting material 3B) used in this Example 2 has a plurality of oblong holes 33 formed in the longitudinal direction, and because it is a long material, it can be attached to a plurality of first members 2A and also to a plurality of second members 2B. In the figure, reference numeral 31 denotes a vertical surface portion, 32 denotes a horizontal surface portion, and a plurality of oblong holes 33 are formed in the vertical surface portion 31. Therefore, since the long connecting member 3B is installed between the plurality of first members 2A, 2A, the distance between the outer panel 1 and the inner formwork 6 facing each other can be firmly maintained.

[0040] The construction procedure for this erection structure is the same as in Example 1, but the long connecting members 3B are attached so that their horizontal surfaces 32 are positioned above each first member 2A and their vertical surfaces 31 are positioned on the end faces of each first member 2A. In this state, the long connecting members 3B are not fixed, so they are fixed in place by attaching fixing bolts 3b to some of the oblong holes 33. The vertical surface 31 of the long connecting member 3B has many oblong holes 33, and the second member 2B is placed so as to pass through these oblong holes 33 and is attached by screwing (barely attached) to the edge of the first member 2A. This work involves the placement of the inner formwork 6 at the same time as the placement of the second member 2B, and the inner formwork 6 is placed in the predetermined position.

[0041] Even in the erection structure of the outer panel 1 of Example 2 having such a configuration, the outer wall is constructed with the outer panel 1 formed by laminating the inner layer material (thermal insulation) 5 on the back side of the exterior materials 1A, 1B, and since the long connecting members 3B are erected between the multiple spacing members 2, 2 (first members 2A, 2A), the outer panel 1 and the inner formwork can be connected without affecting the position or quantity of the rebar, allowing for stable erection of the formwork (outer panel 1). In particular, since it can be used in areas with a large amount of rebar in a rigid frame structure, using the outer panel 1 allows for maximum use of the site area (no space is required for formwork installation), and coupled with the construction of high-rise buildings, it allows for effective use of the land.

[0042] Furthermore, in this embodiment 2, the long connecting member 3B has a plurality of oblong holes 33 along the length direction, so that it can be installed on a large number of spacing members 2, resulting in a structure in which both the straight member 2I and the folded member 2II are installed horizontally. This allows the folded member 2II to be installed in places where the straight member 2I alone cannot be installed due to interference from the reinforcing bars 4, so that the opposing distance between the outer panel 1 and the inner formwork 6 can be more firmly maintained.
