Description

Technical Field

[0001] The present invention relates to a building structure of an exterior material-cum-formwork panel that can be applied to a narrow site, can easily and highly-intensity construct a building, can effectively utilize land, and does not damage the living environment of neighboring areas, in a wall-type structure (WRC) that supports a building by a wall surface (shear wall, structural wall) in reinforced concrete (RC).

Background Art

[0002] Buildings in reinforced concrete (RC) have an advantage that a ramen structure that supports a building by columns and beams such as reinforcing bars and steel frames can be applied to large-scale structures and buildings, and the building can be made high-rise. However, it requires a work space (including scaffolding) for constructing and removing the formwork and a work space for exterior wall construction, and is not preferable from the viewpoints of effective utilization of land and damage to the living environment of neighboring areas. In addition, in this building, the structure is such that columns and beams protrude from the indoor surface, and it is also necessary to install a scaffold on the outer periphery, so there is also a problem that it is not suitable for narrow sites such as urban areas.

[0003] On the other hand, a wall-type structure (WRC) that supports a building by a wall surface (shear wall, structural wall) does not require a scaffold around the building, so the indoor space can be widely used, and construction can be performed over the entire site (= suitable for narrow sites). In addition, although there is also a construction method in this wall-type structure in which a precast wall body is brought to the site for construction, in many cases, a construction method is implemented in which concrete is placed using a spacing member that is a rod-shaped member with a linear side view at the site to construct the wall body.

Disclosure of the Invention

Problems to be Solved by the Invention

[0004] However, in this wall-type structure, it was difficult to adopt it for high-rise buildings due to various conditions (restrictions). Therefore, the applicant considered a structure that would enable effective use of site area in confined spaces by using formwork that also serves as exterior material, without the need to remove the outer formwork. In particular, to apply it to rigid frame structures necessary for high-rise buildings, the applicant considered a structure that allows for the appropriate and easy installation of formwork that also serves as exterior material.

[0005] Therefore, the present invention aims to propose an installation structure for formwork panels that also serve as exterior materials, which can be used to construct buildings easily and with high strength, without compromising the living environment of the surrounding area or being applicable to small plots of land. [Means for solving the problem]

[0006] The present invention has been proposed in view of the above, and relates to an outer panel erection structure in which a plurality of spacing-holding members are arranged in the opposing direction at the distance between the outer panel and the inner formwork, wherein the spacing-holding member consists of a first member that can be assembled to the outer panel and a second member that can be assembled to the inner formwork, and the first member is located on the outer panel side of the reinforcing bars arranged vertically or horizontally at the distance between the opposing surfaces.

[0007] Furthermore, the present invention also proposes an outer panel erection structure characterized in that the first member is connected to the second member via an orthogonal connecting member.

[0008] Furthermore, the present invention also proposes an outer panel erection structure characterized in that the connecting member is integrated with the first member by locking or fastening.

[0009] Furthermore, the present invention also proposes an outer panel erection structure characterized in that the connecting member is rotatably connected to the first member in the erection structure.

[0010] Furthermore, the present invention also proposes an outer panel erection structure characterized in that the connecting member is installed between a plurality of spacing-holding members in the erection structure. [Effects of the Invention]

[0011] In this invention, a plurality of spacing members are arranged in the opposing direction between an outer panel, which is formed by laminating an inner layer material (insulation material) on the back side of the exterior material, and an inner formwork. Each spacing member consists of a first member that can be assembled to the outer panel and a second member that can be assembled to the inner formwork. The first member is positioned on the outer panel side of the reinforcing bars that are arranged vertically or horizontally at the opposing spacing. Therefore, during construction, whether the outer panel is installed first or later on already installed reinforcing bars, the first member and the reinforcing bars do not interfere with each other, allowing the exterior wall panel and reinforcing bars to be installed in the correct positions. Therefore, even for wall structures and buildings where reinforcing bars have already been installed, scaffolding is generally not required around the building, allowing for efficient use of land, without damaging the surrounding living environment, and making it applicable to small plots of land. Moreover, after construction, the outer panels can be used directly as exterior or interior cladding.

[0012] Furthermore, in the erected structure, if the first member is connected to the second member via a perpendicular connecting member, the second member can be easily connected while avoiding the reinforcing bars.

[0013] Furthermore, if the connecting member is integrated with the first member by locking or fastening, the first member can be integrated with the connecting member before being installed. This eliminates the need to install the connecting member during construction, improving on-site work efficiency.

[0014] Furthermore, if the connecting member is rotatably connected to the first member, the connection work of the second member and the connection work with the reinforcing bars will be facilitated.

[0015] Furthermore, when the connecting member is installed between multiple spacing members, this corresponds to, for example, the use of a long connecting member, and the connecting member may be attached to multiple first members in a sprawling manner, or multiple second members may be attached to the connecting member in a sprawling manner. As a result, work such as arranging the connecting member and connecting it to the second members is easy. Moreover, the opposing spacing between the outer panel and the inner formwork can be maintained more firmly. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0017] The outer panel erection structure of the present invention is a structure in which a plurality of spacing members are arranged in the opposing direction at the distance between the outer panel and the inner formwork, wherein the spacing members consist of 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 the first member is located on the outer panel side of the reinforcing bars arranged vertically or horizontally at the distance between the opposing panels.

[0018] The outer panel used in this invention has a structure in which an exterior material is used on the outermost (surface) side, and an inner layer material is laminated on the back side thereof. The exterior material is not limited in terms of material, etc., as long as it has a fixing portion to which the end of the spacing member connecting the outer panel and the inner formwork is attached. The inner layer material is primarily expected to consist of various types of insulation materials, but the material and thickness are not limited as long as sufficient strength to withstand concrete pouring is achieved. Such an outer panel can also be an exterior material (extruded material) with a configuration similar to the formwork-integrated decorative panel that the applicant has previously considered, in which two types of decorative materials are alternately connected, one having a fixing part at one end and the other not having one at the other end, and the end of a spacing member (separator) can be attached to the fixing part. A width of approximately 150 mm is generally common (practical), and multiple exterior materials can be attached to one side of an inner layer material (insulation material) that is usually molded to a width of nearly 600 mm to be used as an outer panel.

[0019] The anchoring portion formed on the exterior material is the part that fixes the end of the spacing member used to secure the space for concrete pouring. Also, the material and molding method of this exterior material are not particularly limited, and facing materials of various materials can be applied. It may be a metal facing material, a hard resin plate, or an extruded profile such as aluminum. Also, a plurality of types of exterior materials may be connected and used, or an exterior material having a fixing portion and an exterior material not provided with a fixing portion may be combined and used as in the illustrated embodiment described later. Although the thickness is not limited, generally, the thickness is 1.2 to 1.6 mm or more, and it is more desirable to have a strength such that the surface is not distorted or deformed even when a certain amount of stress such as the concrete placement pressure acts.

[0020] The inner layer material (heat insulating material) can be any material as long as it does not rupture under the concrete placement pressure as described above. It may be a single layer, or a laminate of two or more heat insulating materials having different characteristics, or it may be one using a separate reinforcing material or the like. For example, various synthetic resin foams that require a predetermined wall thickness may be used, or gypsum boards, or inorganic materials such as PC panels, ALC panels, other fireproof materials, and refractory materials may be used. It may be configured to be integrated in advance on one side (one side) of the exterior material, or it may be prepared separately.

[0021] Regarding the fixing portion provided on the back side of the exterior material, to explain it in more detail, any thing that can connect the ends of the spacing holding members may be used. For example, when the ends of the spacing holding members are male screw portions, various corner nuts or a plate-like material with a plurality of female screw portions screwed thereon may be integrated as the fixing portion, or the overlapping piece may be made thick and tapped (female screw processed). Particularly, a space portion that is open on the side or the back side may be provided on the back side of the face plate portion, and a corner nut or the like having a screw portion may be attached in the space portion to form a fixing portion. When a general-purpose nut is used, since the head of the corner nut is square, co-rotation (rotation) is prevented when attaching the spacing holding member. In addition, it is desirable to interpose a buffer material that prevents contact between the corner nut or the like and the exterior material in this space portion. This buffer material may be the same material as the inner layer material (heat insulating material), or an elastic material such as rubber.

[0022] The aforementioned spacing member (separator) is a member whose end is attached to the fixing portion formed in the exterior material as described above. This spacing member is a rod-shaped material with a straight side view and consists of a first member that can be assembled to the outer panel and a second member that can be assembled to the inner formwork. The first member is located on the outer panel side of the reinforcing bars (vertical and horizontal bars) that are arranged vertically or horizontally at the opposing intervals. The statement that the first member described above is "located on the outer panel side of the reinforcing bars" means that the tip of the first member (= the edge on the inner formwork side) is positioned where there are no reinforcing bars. Note that the outer panel may be installed either after the reinforcing bars are laid or before the reinforcing bars are laid. Therefore, if we define the area where reinforcing bars are present as the "interior" and the area where they are not as the "exterior," then when installing the outer panel on the "exterior" of reinforcing bars already placed in the "interior," the tip of the first member will not interfere with the reinforcing bars. Furthermore, when placing reinforcing bars after the outer panel has been installed, the reinforcing bars will not interfere with the first member, making installation easy.

[0023] Furthermore, conventional spacing members have a first member that protrudes into the opposing space between the outer panel and the inner formwork. As a result, they can come into contact with or get caught on vertically or horizontally arranged reinforcing bars (longitudinal and transverse reinforcing bars), making installation very time-consuming and potentially reducing strength. In contrast, in the present invention, as described above, the first member is located on the outer panel side of the reinforcing bars arranged at the aforementioned opposing intervals, so it never comes into contact with or gets caught on the reinforcing bars, i.e., it never interferes with them, and the outer panel can be easily installed in the correct position.

[0024] Furthermore, while a structure in which the first and second members of a spacing member can be freely connected or separated by tightening is already known, by applying a cylindrical structure in which a core material exists inside and an outer shell material surrounds it to this spacing member (at least the second member), the core material located inside the first and second members receives the pouring pressure when concrete is poured, and after the concrete is poured, the core material can be removed from the outside of the inner formwork and reused. On the other hand, the outer shell material of the first member and the second member, which do not employ a cylindrical structure, are embedded in the concrete. Furthermore, since the first member is located on the outer panel side of the reinforcing bars arranged at the aforementioned opposing intervals, the length of the first member becomes shorter, and the length of the second member becomes longer accordingly. By adopting such a cylindrical structure, the buried first member can be made shorter, and the core material of the reused second member can be made longer.

[0025] The first member may be connected to the second member via a perpendicular connecting member. That is, the spacing member used may be a straight member that directly (linearly) connects the first member and the second member, or a folded member that indirectly connects the first member and the second member via a connecting member.

[0026] The connecting member is connected (linked) between the first member and the second member of the folded material, and is a member in the shape of a short plate, strip, L-shape, Z-shape, U-shape, etc., and can be appropriately selected from steel, high-strength resin, etc., having the strength required for the installation location. Furthermore, the first member, connecting member, and second member may be fastened together primarily by direct fastening using male and female threaded portions, or by clamping them together using the same male and female threads. The female threaded portion may be formed by fixing a nut or the like, or by tapping.

[0027] The shape and length of this connecting member are not limited, but for example, an L-shaped elongated connecting member may be arranged to span multiple spacing members by forming multiple holes in the longitudinal direction. The holes in this elongated connecting member are used to fix the first member or the second member, so they may be circular or oval holes. Furthermore, these holes may be used to erect multiple first members or to erect multiple second members. Furthermore, for example, a short, piece-shaped connecting member can be rotated (rotated or spun while maintaining a perpendicular position) to avoid the surrounding reinforcing bars (rotate to a location where it does not interfere).

[0028] The reinforcing bars placed in the opposing spaces (concrete pouring spaces) formed by multiple spacing members may be individual reinforcing bars, or they may be reinforced concrete columns (columnar reinforcing bars) of a rigid frame structure consisting of multiple reinforcing bar bundles. In other words, these reinforcing bars include both the reinforcing bars that form the walls of a wall-type structure (WRC) and the columnar reinforcing bars of a rigid frame structure. Furthermore, the method (structure) of connecting the aforementioned connecting material to the reinforcing bar may be, for example, by connecting with a strong strip-shaped material (which may be bent or fastened as needed), or by spot welding.

[0029] Furthermore, as mentioned above, the outer panel is constructed by laminating an inner layer material (insulation material) on the back side of the exterior material. For example, it is possible to form the exterior surface with multiple exterior materials and the insulation layer with a single inner layer material, and the insulation layer side can be used as a space for pouring concrete. After construction, a concrete building can be constructed with the exterior material laid on its surface.

[0030] Thus, the present invention comprises a first member that can be assembled to the outer panel and a second member that can be assembled to the inner formwork, as a spacing member that forms the opposing spacing between the outer panel and the inner formwork. Since the first member is located on the outer panel side of the reinforcing bars that are arranged vertically or horizontally in the opposing spacing, the tip of the first member does not interfere with the reinforcing bars that have already been installed, and the outer panel can be easily installed in the correct position. Furthermore, when installing reinforcing bars after the outer panel has been installed, the tip of the first member does not interfere with the reinforcing bars, and the reinforcing bars can be easily installed in the correct position. Therefore, even for wall structures and buildings where reinforcing bars are already installed internally, scaffolding is generally not required around the building, allowing for efficient use of land, without damaging the surrounding living environment, and making it applicable to narrow plots of land. Moreover, after construction, the outer panels can be used directly as exterior or interior cladding. In particular, it can be used in areas of rigid frame structures with a large amount of reinforcing bars, allowing for easy and appropriate installation (erection) of the outer panels, maximizing the use of the site area (eliminating the need for formwork and scaffolding space), and, combined with the possibility of increasing the height of the building, enabling efficient use of land. Furthermore, since the outer wall is constructed using outer panels with an inner layer material (insulation) laminated on the back side of the exterior material, scaffolding is generally not required around the structure. This allows for efficient use of land, does not impair the living environment of neighbors, and can be applied to small plots of land. Moreover, after construction, the outer panels can be used as exterior or inner layer materials. [Examples]

[0031] The erection structure of the exterior material / formwork panel (outer panel) 1 of Embodiment 1 shown in Figures 1(a) and 1(b) is such that a plurality of spacing members 2 are arranged in the opposing direction at the distance 5 between the outer panel 1 and an inner formwork (6) (not shown). The spacing members 2 consist of a first member 2A that can be assembled to the outer panel 1 and a second member (2B) (not shown) that can be assembled to the inner formwork. The first member 2A is located on the outer panel 1 side of the reinforcing bars 4 that are arranged vertically or horizontally at the distance 5. That is, the tip (edge ​​on the inner vertical frame side) 21 of the first member 2A is located in a position where there are no reinforcing bars 4. Therefore, when installing the outer panel 1 outside of already installed reinforcing bars 4, the tip 21 of the first member 2A does not interfere with the reinforcing bars 4, and it can be easily installed in the correct position.

[0032] As shown in Figures 2(a) and (b), 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 insulation layer formed by an interior layer material (insulation material) 1C arranged on the back side thereof. Since two of each of the two types of exterior materials 1A and 1B are alternately laminated on the surface side of one insulation material 1C, the outer panel 1 is formed by being connected in the width direction. As shown in Figure 2(c), the exterior surface consists of an exterior material 1A having a space 14 on the back side of the faceplate portion 11 which is the finished surface, and an exterior material 1B without a space 14. A protrusion 111 is provided in the approximate center of each faceplate portion 11, projecting toward the surface in an approximate T shape. Of these, the exterior material 1A having the space 14 is provided with an engaging portion 12a and an engaging receiving portion 12b at its edge, while the exterior material 1B without the space 14 is provided with an engaging portion 12c and an engaging receiving portion 12d at its edge, and is an extruded aluminum profile. Then, the engaging portion 12a of the exterior material 1A and the engaging receiving portion 12d of the exterior material 1B are assembled in an engaged manner, forming a molded part with a roughly U-shaped space 14, and the engaging receiving portion 12b of the exterior material 1A and the engaging portion 12c of the exterior material 1B are assembled in an engaged manner. The space 14 houses a fixing device 13 such as a nut, and serves as a fixing part that secures the end of the first member 2A.

[0033] As shown in Figure 2(a), the left and right edges of the thermal insulation material 1C are notched from the front side on one side and from the back side on the other side on the other side, allowing them to overlap in a rabbet-like manner. The edge facing the overlapping portion is designated as the overlapping portion 15a, and the other end that overlaps with the overlapping portion 15a is designated as the overlapped portion 15b. A recess 16 is formed in the longitudinal direction of the thermal insulation material 1C approximately in the center, into which the space 14 of the exterior material 1A is fitted. Furthermore, the reinforcing bars 4 include vertical reinforcing bars 4A arranged vertically, as shown in Figures 1(a) and (b), and Figures 2(a) and (b), and horizontal reinforcing bars 4B arranged horizontally.

[0034] Therefore, as shown in Figure 2(d), when installing the outer panel 1 on the outside of the reinforcing bars 4, such as the vertical reinforcing bars 4A and horizontal reinforcing bars, which have already been installed, the tip 21 of the first member 2A does not interfere with the reinforcing bars 4, and it can be easily installed in the correct position. The second member 2B is connected to the base end of the tip 21 of each first member 2A, and an inner formwork 6 is provided at the tip of the second member 2B. The second member 2B has a cylindrical structure with a core material 22 inside and an outer shell material 23 surrounding it, and its base end (rear end) extends to the outside of the inner formwork 6.

[0035] Thus, as Example 1, Figure 1(a) shows a structure in which the outer formwork is formed by joining the outer panels 1 of the above configuration side by side. As shown in Figure 2(a), one outer panel 1 has two exterior materials 1A and 1B stacked in an overlapping manner on the surface side of a single insulation material 1C, and the first member 2A of the spacing member 2 is attached to the back side in a protruding manner. Furthermore, since the tip 21 of each first member 2A is positioned where there are no reinforcing bars 4 (vertical reinforcing bars 4A and horizontal reinforcing bars 4B), when installing the outer panel 1 outside the already installed reinforcing bars 4, the tip 21 of the first member 2A does not interfere with the vertical reinforcing bars 4A or horizontal reinforcing bars 4B, allowing for easy installation in the correct position. As a result, the outer panel 1 and inner formwork 6 can be connected without affecting the position or quantity of reinforcing bars 4, enabling the stable construction of formwork (outer panel 1). In particular, it can be used in areas of rigid frame structures with a large amount of reinforcing bars, and by using the outer panel 1, the site area can be used to the maximum extent possible (no space is required for formwork installation), and in combination with the increasing height of the building section, the land can be used effectively. Furthermore, since the construction structure of this Example 1 does not, in principle, require scaffolding around the building, it enables effective use of land, does not impair the living environment of the surrounding area, and can be applied even to small plots of land. Furthermore, after construction, the outer panel 1 can be used as is as exterior material 1A, 1B and interior material 1C.

[0036] To briefly explain the construction procedure of the erected structure in this embodiment 1, after the outer panel 1 is installed in a predetermined position, vertical reinforcing bars 4A are arranged vertically and horizontal reinforcing bars 4B are arranged horizontally in the internal space, or the vertical reinforcing bars 4A and horizontal reinforcing bars 4B are arranged in advance, and then the outer panel 1 is installed on the outside. After that, the second member 2B and the inner formwork 6 are attached to the tip 21 of each first member 2A. The first member 2A is attached to the outer panel 1 by screwing (barely attaching) the male threaded portion at the tip of the first member 2A into the female threaded portion formed in the space 14. Furthermore, concrete (not shown) is poured into the gap 5 between the installed outer panel 1 and the inner formwork 6. After curing (hardening), the inner core material 22, inner formwork 6, and fastening members that form the second member 2B are removed and reused, but the outer shell material 23 that forms the first member 2A and the second member 2B are embedded in the concrete. [Example 2]

[0037] Figures 3(a) and 3(b) show an example of Embodiment 2 in which the first member 2A is connected to the second member 2B via a perpendicular connecting member 3 (long connecting member 3A). Note that the vertical reinforcement bars 4A and horizontal reinforcement bars 4B are omitted from the diagram.

[0038] The long connecting member 3A used in this embodiment 2 is made of L-shaped steel and has multiple oval holes 33 formed in the longitudinal direction. Because it is a long member, it can be erected on a large number of first members 2A and a large number of second members 2B. In the figure, reference numeral 31 denotes the vertical surface and 32 denotes the horizontal surface on which the multiple oval holes 33 are formed.

[0039] As in this embodiment 2, when the first member 2A is connected to the second member 2B via a long connecting member 3A as a perpendicular connecting member 3, the second member 2B can be easily connected while avoiding the reinforcing bars 4A and 4B, which are not shown in the figure. In particular, in this embodiment 2, since a long connecting member 3A made of L-shaped steel is used, it contributes to the unity of multiple first members 2A and second members 2B, and can stably maintain the spacing. [Example 3]

[0040] Figure 4(a) shows an example of Embodiment 3 in which the first member 2A is connected to the second member 2B via a piece-shaped connecting member 3B as an orthogonal connecting member 3. Note that in the diagram, all but one vertical reinforcing bar 4A are omitted, as are the other reinforcing bars 4.

[0041] The piece-shaped connecting member 3B used in this embodiment 3 is an elliptical plate in plan view with two circular holes arranged side by side. A fastener 3d for fixing to the tip of the first member 2A is attached to one of the circular holes, and a nut for fastening to the tip of the second member 2B is attached to the other circular hole. Therefore, this piece-shaped connecting member 3B can be attached to the first member 2A by fastening the fixing device 3d, and the second member 2B can be attached by fastening it to the fixed nut.

[0042] As in this embodiment 3, when the first member 2A is connected to the second member 2B via a piece-shaped connecting member 3B as a perpendicular connecting member 3, the second member 2B can be easily connected while avoiding the single longitudinal reinforcing bar 4A shown and the transverse reinforcing bars 4B not shown. In particular, in this embodiment 3, since a piece-shaped connecting member 3B with an elliptical plate shape in plan view is used, it is possible to rotate 360 ​​degrees around the end of the first member 2A, making it easy to avoid (rotate to a location where there is no interference with) the vertical reinforcement bars 4A and horizontal reinforcement bars 4B that have been installed. [Example 4]

[0043] Figures 4(b) and 4(c) show an example of Embodiment 4 in which the first member 2A is connected to the second member 2B via a U-shaped connecting member 3C as a right-angle connecting member 3. Note that the vertical reinforcement bars 4A and horizontal reinforcement bars 4B are omitted in the same diagram.

[0044] The U-shaped connecting member 3C used in this embodiment 4 consists of rectangular plate members 34 and 36, which have two circular holes arranged side by side as shown in Figure (c), and a rod member 35 that connects them. One plate member 36 has a circular hole 360 ​​into which the first member 2A can rotate (swivel and slide), and the other plate member 34 has a circular hole 340 arranged side by side with a female thread that allows the second member 2B to be attached.

[0045] As in this embodiment 4, when the first member 2A is connected to the second member 2B via a U-shaped connecting member 3C as a perpendicular connecting member 3, the first member 2A and the second member 2B can be arranged in a dividing straight line, which stabilizes the positioning of the spacing member 2 and improves workability. Furthermore, this U-shaped connecting member 3C can also be used to enclose the vertical reinforcing bars 4A (not shown) from the side. [Example 5]

[0046] Figure 5 shows an example of Example 5 in which a reinforced steel column (columnar reinforcement) 4II, consisting of multiple reinforcement bundles, is constructed at the corner of the foundation 7. The right side of the figure, as well as the vertical and horizontal reinforcement other than the reinforced steel column 4II, are omitted. Unlike the reinforcing bars 4 used in Figure 1(a) above, which are arranged individually, this reinforced steel column 4II is placed in the corner of the interior space. Unlike the construction of a typical rigid frame structure, instead of using long vertical bars, vertical bars of a predetermined length are connected in the height direction without scaffolding being erected around them and used as vertical bars 4a.

[0047] In Figure 5, multiple vertical reinforcement bars 4a are arranged and fixed in a rectangular shape in plan view at the corner of the foundation 7, and the symbol 4b shown in the figure is a strip-shaped reinforcement bar surrounding the multiple vertical reinforcement bars 4a. Furthermore, the reinforced steel column 4II, consisting of the multiple vertical bars 4a and strip-shaped bars 4b, is surrounded in an L-shape in plan view by two outer panels 1,1. In this state, the outer panel 1 already has the first member 2A installed, so it is in the state shown in Figure 2(a).

[0048] The erection structure of the outer panel 1 in Embodiment 5, which has this configuration, allows the outer panel 1 to be easily installed in the appropriate position, and can therefore be used even in areas of rigid frame structures with a large amount of rebar. By using the outer panel 1, the site area can be used to the maximum extent possible (no space is required for formwork installation or scaffolding), and in combination with the height of the building section, the land can be used effectively. Furthermore, this construction method, in principle, does not require scaffolding around the building, allowing for efficient use of land, without harming the surrounding living environment, and can be applied even to small plots of land. Furthermore, after construction, the outer panel 1 can be used as is as exterior material 1A, 1B and interior material 1C. [Explanation of symbols]
