[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structural wall body used in a building, particularly a steel frame building, which does not require columns, beams, girders, and braces in a low-rise steel frame building,
At the same time, the invention provides a novel structural wall body for constructing a building having an outer insulation structure, and is an invention belonging to the field of construction.

[0002]

2. Description of the Related Art [Prior Art 1 (FIGS. 14 and 15)] FIGS. 14 and 15 use a corrugated steel plate as a wall plate and have been proposed for the purpose of providing a heat insulating material and saving labor in construction. And is disclosed as Japanese Patent Laid-Open No. 11-229490. That is, the foundation, pillars,
It is constructed in the order of beams, girders, floors, roofs, etc., and the wall folding plate 70 is used as the wall body, and the floor folding plate 80 is also used as the floor plate.

The wall folding plate 70 has a joining metal fitting 50 mounted on a concrete foundation B, and a rising piece 53 bent into the same shape as the wall folding plate 70 is fixed on the metal fitting 50 as shown in FIG. 14 (A). Then, the lower end of the wall folding plate 70 is bolted to the rising piece 53 so as to stand upright.
As shown in (B), the beam 60 having the wall folding plate joining metal fitting 61 and the floor folding plate receiving metal fitting 66 fixed to the peripheral surface is fixed, and the floor folding plate 80 and the wall on the upper floor are sequentially inserted through the beam 60. The folding plate 70 is shown in FIG.
It is fixed as shown in (A) to construct the frame of a steel frame building.

In addition, on the wall folding plate 70, injection holes 71 are previously arranged at appropriate places, and on both inner and outer surfaces of the wall folding plate 70, structural flat plates 72 having injection holes 73 at appropriate places are constructed. After the fixing work is carried out with, the heat insulating material 74 is injected from the injection hole 73 of the flat plate 72, and the heat insulating material 74 is filled into the wall body of the three-layer structure through the injection hole 71 of the folding plate 70. That is, as for the wall body, the wall folding plate 70 is first erected by site construction, and then the structural flat plates 72 are fixed to both sides of the wall folding plate as shown in FIG. 15B to form a three-layer structure wall body. Then, after the heat insulating material 74 is filled into the wall body to construct the wall structure material, the exterior material and the interior material are attached to the wall structure material.

[Conventional Example 2 (FIG. 16)] As shown in FIG. 16, as a formwork for placing a concrete structure, on one side, a vertical plate is used as a formboard by a conventional method. On the other side, and on the other side, a heat insulating material that also serves as a formwork and is embedded with synthetic wood as a base material that also serves as a vertical edge is placed as a template with a horizontal pattern (edge thick). Concrete is poured between the plate and the heat insulating material, the formwork is removed, and then the concrete wall is integrated with the heat insulating material. The synthetic wood is used as a base material for finishing the building. That is, only a heat insulating material that also serves as a formwork, which is integrated with a synthetic wood as a base material, is previously manufactured as a panel as one member for wall construction, and a concrete wall is integrally molded with the heat insulating material as an on-site construction. .

[0006]

In the above-mentioned conventional example 1, when arranging the wall body, it is necessary to assemble the wall folding plate 70 and the structural flat plate 72 together as a wall body after carrying them into the site. Even in the on-site assembly, the rising piece 53 and the joint fitting 61 are small members and are complicated and time-consuming work for precise attachment to the folding plate 70.

Further, it is difficult to fill the heat insulating material into the three-layer structure wall body, and it is almost impossible to fill the entire surface homogeneously. The filling of the expandable synthetic resin is a special measure for dealing with deformation and damage due to foaming pressure. It is necessary to use various protective means together, and in the case of injecting the inorganic heat insulating material, the injection hole 71 of the wall folding plate 70 needs to have a large diameter and a large number of holes so that the heat insulating material is dispersed in the wall body. The perforation of the injection holes 71 and 73 causes a decrease in the strength of the wall body. Therefore, the construction of a wall with insulation is
Although it is almost impossible to provide a uniform heat insulating function, it is a difficult and difficult site work that involves a decrease in the strength of the wall body, and the construction wall body also has exterior and interior materials. Need to be fixed, there are many building materials and tools to be carried to the site, many site operations are complicated, and construction efficiency is poor.

Further, in the above-mentioned conventional example 2, the wall body is a concrete wall formed by on-site construction and cannot be manufactured in a factory. Of course, only the heat insulating material that also serves as a mold with embedded base material is a panel that can be produced at the factory and can be transported, but it is not a wall panel itself, but it is simply used as a mold when pouring wall concrete on site. is there.
Therefore, not only the wall other than the concrete wall cannot be formed, but also the wall can be formed only on-site construction, and the wall cannot be formed into a panel.

According to the present invention, columns, beams, girders, structural walls capable of constructing a steel frame building without braces can be panelized for factory production, and have sufficient strength with columns and bracing functions. Provides a new and epoch-making structural wall body as a composite panel that also has an external heat insulation function and also integrates the base material of the exterior material when finishing the building or the exterior material itself However, especially in the field of low-rise steel building,
The ratio of factory work can be increased to achieve rationalization and efficiency of construction, and at the same time, it is possible to provide a building with an external heat insulation structure that has high sound insulation and sound absorption properties and is excellent in the living environment. is there.

[0010]

[Means and Actions for Solving the Problems] The first invention is
For example, as shown in FIG. 1, one thin steel plate is bent into a substantially corrugated cross section to form a structural wall plate 1 in a shape that can withstand vertical stress F ₁ and horizontal stress F ₂ with an apparent thickness W ₁ , and a bottom plate. 7 _B , 8 _B
And the side plate 7 _S, inner and outer protrusion formed by folding of the wall plate 1 is fitted to the upper and lower ends of the wall plate 1 the upper and lower frames 7,8 consisting of a U-shaped cross section shape steel having a 8 _S 4, 5 and the inner and outer side plates 7 _S , 8 _{S of the} upper and lower frames are fixedly integrated with each other, and a layer of the heat insulating material 2 in which the base material 3 such as a furring strip is buried and exposed in a proper position is integrally fixed on the outer side surface. It is a structural wall of a building (claim 1).

The “apparent thickness W ₁ ” is an important factor that affects the anti-buckling force, that is, the strength to withstand the vertical load F ₁ , together with the wall thickness of the thin steel plate and the height L ₁ of the wall plate 1. If the thin steel sheets have the same thickness, the anti-buckling force becomes large if the apparent thickness W ₁ is large, and if the apparent thickness W ₁ is the same, the anti-buckling force becomes large. Therefore, it is possible to deal with the two-story wall body 10 and the four-story wall body 10 by selecting the wall thickness of the thin steel plate under the same apparent thickness W ₁ .

Further, the meaning of "a substantially corrugated section" of the wall plate 1 is as shown in FIG.
It means not only that the inner and outer protruding portions are bent in a trapezoidal shape like a flat plate, but also a broadly defined waveform that is bent in a form that can withstand the vertical stress F ₁ and the horizontal stress F ₂ . In addition, "insulation material 2"
It means a commonly used heat insulating material, and may be any heat insulating material that can firmly hold the base material 3 by embedding it in a form in which the surface is exposed. In addition, the “integrated fixing” of the layers of the heat insulating material 2 is performed in a separate process from the base material 3
It also includes fixing and fixing of the already formed layer in which is embedded and fixed. Further, the "base material 3" is intended to include not only the horizontal furring strips in FIG. 1 but also the vertical furring strips, and is for attaching outer wall materials, furring strips, etc. in the finishing process of the building. Also, the base material 3
The meaning of "exposing under the ground" includes the one in which the inner surface of the base material 3 is in contact with the wall plate 1 and the one in which the base material 3 is fixed in a floating state in the heat insulating material. _3F is intended to include a wide range of exposures, including those that are flush with the heat insulating material, those that protrude from the heat insulating material, and those that substantially correspond to the exposure that can be clearly seen from the surface.

Therefore, in the first aspect of the invention, the wall body 10 withstands the vertical stress F ₁ transmitted from the floor of the building to the wall body 10 and the horizontal stress F ₂ acting on the wall surface such as tensile compression. Since it has strength, it can be used as a structural material for steel-framed buildings without using columns, beams, girders, and braces, and the wall plate 1 that can withstand various stresses F ₁ and F ₂ is formed by bending thin steel plates. Since the wall body 10 itself is relatively lightweight, the amount of steel used in the steel frame building can be saved and the weight of the building itself can be reduced.

Further, the wall body 10 as a panel has an outer surface.
Since it has a layer of the heat insulating material 2, the construction of the outer heat insulating structure of the building at the site can be omitted, and the base material 3 is homogeneous,
It is embedded in the heat insulation layer formed with high precision and exposed.
Therefore, it is easy to attach the exterior material and
It is also possible to form a complete outer insulation outer wall that can prevent a thermal bridge from the exterior material to the wall plate through the base material. Also, the base material 3
Since the wall body 10 is integrally present on the outer surface of the wall body 10, it is easy to attach an outer wall material such as siding, and since the wall body 10 as a panel includes a heat insulating material and a base material, the number of building members is reduced. And, the number of construction man-hours can be reduced, and the rationalization of construction can be achieved.

The recess 10 _Z formed between the inner protruding portions 4 and 4 of the wall plate 1 can be used for filling the sound absorbing and heat insulating material G,
As a result, it becomes easy to construct a building having an external heat insulating structure and being rich in sound absorption. In addition, since the wall body 10 can be manufactured as a standard product panel in the factory from the bending process of the thin steel plate to the provision of the heat insulating material 2, it is easy to manufacture and store the homogeneous wall body 10, The building management system (system) from the design of the building to the completion can be rationalized.

Further, it is preferable that a synthetic resin foam such as polyurethane is adopted as the heat insulating material 2, and the heat insulating material is integrally fixed to the wall plate 1 by the foam coagulation adhesive force (claim 2).
In this case, it is possible to firmly and uniformly fix the wall plate 1 by the conventional molding means without being influenced by the outer surface shape of the wall plate 1, and the base material 3 can be disposed in the embedded exposed form even if the surface 3 of the base material 3 is exposed. _This can be achieved simply by installing _F in the mold and foam-molding the heat insulating material 2, and it is possible to rationalize the production of the panelized wall body 10, facilitating the factory production of the wall body 10 as a uniform product of high quality. Become.

The second invention is, for example, as shown in FIG.
The structural wall plate 1 is formed in such a manner that one thin steel plate is bent into a substantially corrugated cross section to withstand the vertical stress F ₁ and the horizontal stress F ₂ with an apparent thickness W ₁ , and the bottom plates 7 _B , 8 _B and side plates are formed. 7 _S, 8 _S consists U-shaped cross section of the shaped steel having the upper and lower frames 7,8 the wall plate 1 of the upper and lower ends the inner and outer protrusion 4 formed by folding of the wall plate 1 is fitted to, 5 and the inner and outer side plates 7 _S and 8 _{S of the} upper and lower frames are fixedly integrated with each other, and a layer of the heat insulating material 2 having the exterior material 40 laminated and fixed to the outer surface is integrally fixed to the outer surface. (Claim 3).

That is, the second aspect of the present invention is one in which the exterior material 40 is directly adhered and integrated to the heat insulating material 2, and the exterior material is attached by post-processing (on-site work) to the base material that is integrally adhered and integrated in the first aspect of the invention. In contrast to the attachment, the second invention no longer requires the work of attaching the exterior material on site. And
The frame structure of the wall body formed by the wall plate 1 and the upper and lower frames 7 and 8 before applying the heat insulating material 2 is the wall body 10 'of the second invention (claim 3) and the wall of the first invention (claim 1). Because it is the same as the body 10,
Of course, the mechanical properties of both wall panels are the same, and even the wall body 10 'of the second invention has the same function as the wall body 10 of the first invention as a structural material. There is.

The "exterior material" in the second aspect of the invention broadly means a conventional exterior surface material such as siding (wall board) used for exterior walls, structural plywood as a base material for ceramic tiles, and the like. The "lamination fixation" of the exterior material to the heat insulating material includes not only integral molding with the heat insulating material but also surface bonding of both the heat insulating material and the exterior material as a ready-made molded product. Therefore, if a steel frame building is constructed by using the wall body 10 'of the present invention (Claim 3) as a wall structure material, the exterior material can be attached uniformly and with high accuracy only by assembling the outer wall surface with the wall body 10'. In the case where the wall body 10 of the first invention is used for the construction of a low-rise steel building, the external heat insulation building becomes unnecessary, and the work of installing the heat insulation material for the outer heat insulation and the work of installing the exterior material (wall plate, tile wall base plate, etc.) are unnecessary. More labor saving and rationalization can be achieved.

Also in the second invention, it is preferable that the heat insulating material 2 is a synthetic resin foam, and the heat insulating material 2 is integrally fixed to the wall plate 1 and the exterior material 40 by the foam solidification adhesive force. (Claim 4). In this case, since the foamed synthetic resin to serve as the heat insulating material 2 is injected and foamed into the cavity formed by the outer surface of the wall plate 1 and the inner surface of the exterior material by the conventional molding means of the synthetic resin foam, the exterior material is formed. Even if the inner surface of 40 is rough or provided with protrusions, it can be integrally molded without any trouble. Therefore, by selectively applying the sticking force increasing means (roughening, anchor piece attachment) to the inner surface of the exterior material according to the solidification adhesive strength of the heat insulating material 2, the wall body 10 ′ provided with the exterior material is a factory production panel. As a uniform and high quality standard product, it can be manufactured regardless of the busy season.

Further, the wall plate 1 in the wall 10, 10 'are preferably spliced a plurality of wall panels 1 at the side edge 1 _E (claim 5). In addition, the meaning of "a plurality of wall plates" includes not only a plurality of wall plates 1 having the same size but also a plurality of wall plates 1 having different width dimensions. Is the side edge 1
_{E It} means not only the lap joint of the comrades but also the lap joint using the joint piece, and "side edge 1 _E " means not only the bent end of the original plate but also the cut end of the dimension. In this case, the original plate of the thin steel plate is shaped to have a relatively small width, which makes it easy to obtain and process the material, and the lap joint part serves as a reinforcement part, which is advantageous for improving the anti-buckling force. is there. The lap joint means may be fixed by a drill screw, but if the inner surfaces of the wall bodies 10 and 10 'have protrusions, the flatness of the fixing surface of the interior finishing material is impaired, which is disadvantageous for abutting and fixing the flat plate interior material. Therefore, it is preferable to perform fixing by spot welding so as to suppress the formation of the protruding portion to the minimum.

The wall plate 1 also includes an inwardly projecting flat plate portion 4,
It is preferable to fold it into a form including the outer protruding flat plate portion 5 and the inclined plate portion 6 between the flat plate portions 4 and 5 (claim 6). In this case, since the wall plate 1 does not have a curved surface, the base material (horizontal furring strip) 3 or the exterior material anchor piece 41 is attached to the outer surface of the wall board 1 or the interior base material of the flat plate portion 4 on the inner surface side is used. Is not only advantageous for the use of
When the width L ₂ of ′ ′ is shortened or lengthened, the side ends 1 _{E of} the wall plate 1 can be easily slidably adjusted to each other, and the joint pieces can be abutted easily. The work of fixing the upper and lower frames 7 and 8 together becomes easy.

The wall plate 1 has a wall thickness T ₁ of about 1.2 mm.
The apparent thickness W ₁ is about 100 mm, the width a of each of the flat plate portions 4 and 5 is about 130 mm, the center-to-center dimension L ₄ of the inner flat plate portion 4 has a dimension corresponding to the building material market size, and the inclination is The inclination angle θ ₁ of the plate portion 6 is preferably about 45 ° (claim 7). In this case, even if the wall plate 1 is formed of one thin steel plate, it has a strength of about 11 t / m in consideration of the safety factor 1 / √3 and does not use columns, beams, girders, and braces. Even if it is adopted in the wall construction method, it can withstand up to 4 stories.

Although the apparent thickness W ₁ is an important factor for the anti-vertical load force (buckling strength), when the lower frame width W ₂ is 100 mm or less, mortar construction etc. on the lower frame 8 during erection, etc. Has a problem in workability, if the apparent thickness W ₁ is a little less than 100 mm, it is possible to use a highly versatile 100 mm lightweight die steel with easily obtained upper and lower frames 7 and 8, and a wall thickness T of 1 mm or less. If so, it is unsuitable for conventional spot welding.
The 5 ° inclination can balance the horizontal stress F ₂ (tensile, compression) on the wall plate 1, and the inner flat plate portion 4
If the center-to-center dimension L ₄ of the building material is the market dimension of the building material (1/1), it is easy to determine the mounting position during interior construction and the mounting work becomes easier. It is advantageous in practice, and is particularly advantageous as a structural wall body of 4 stories or less.

Further, it is preferable that the side end 1 _E of the wall plate 1 is in the form of a projecting flat plate, and the ends of the unit walls 10, 10 'are in the form of outer projecting flat plates (claim 9). In this case, the lap joint of the wall plates 1 enables the sliding adjustment of the flat plate portions to each other, and it is easy to deal with the change in the dimension of the wall width L ₂ .
Since the recess 10 _Z from the inside is formed at the end of the wall body,
Wall 10, 10 'is a of the wall mutual lateral coupling operation during Kenzuke, a easy fitting of the joint piece of the lower frame base plate 8 in the _B, the linear connected as shown in FIGS. 4 and 5 Also, the corner connection becomes easy.

Further, as shown in FIGS. 9 and 10, one side of the vertical frame 24 of angle steel is fixed to the wall plate side end 1 _E of the unit wall bodies 10 and 10 ′ and is attached to both side surfaces of the wall bodies 10 and 10 ′. It is preferable to provide the bolt fastening holes H ₅ on both side surfaces 24 _S of the vertical frame 24, respectively. In this case, the vertical frame 24 functions as a reinforcing material, and the side surfaces 24 _S can be used also as temporary fixing when the wall bodies 10 or 10 ′ are connected to each other on the left and right sides, which facilitates and speeds up the construction work. This makes it possible to join and fix the window upper wall body and the window lower wall body at the wall surface opening.

Further, as shown in FIG. 11, the inside and outside of the wall plate 1

In order to form a flat surface of 0,10 ', the flat plate portion 4 is
It is possible to install the interior material (gypsum board) smoothly without any steps.
I can.

Further, it is preferable that the base material 3 is fixed by the outer protruding portion 5 of the wall plate 1 (claim 12). In this case, not only lightweight siding as an exterior material but also a heavy outer wall material can be attached, and the work of attaching the base material 3 to the outer protruding portion 5 is easy. Further, even when the injection molding of the synthetic resin foam is applied as the heat insulating material 2, the displacement of the base material 3 due to the filling pressure of the synthetic resin foam and the foaming pressure can be reliably prevented.

The base material 3 is preferably a heat-defective conductor such as wood or a plastic material (claim 13).
If the base material 3 is a heat-defective conductor, even if the metal vertical furring strip 16 is attached as shown in FIG. 8A, there is no thermal bridge from the vertical furring strip 16 to the wallboard 1, and the wallboard The heat transfer h ₂ to 1 is
Only the amount from the outside heat h ₁ through the drill screw S,
Outer protruding flat plate portion 5 → inclined plate portion 6 → inner protruding flat plate portion 4
It is only reduced and transmitted to the interior material 20 through the route of. Moreover, since the base material also has a heat insulating function, the thermal function of the heat insulating material 2 is not impaired. Therefore, the thickness of the heat insulating material 2 from the surface of the heat insulating material 2 to the outer protruding portion 5 of the wall plate 1 (the thinnest thickness of the heat insulating material 2) can be made relatively small, and the base material 3 is It is also possible to dispose the protrusion 5 from the surface in a contact form, and the degree of freedom in selecting the shape and size of the base material 3 is increased.

The base material 3 of the heat-defective conductor has a small piece of packing 30 between it and the outer protruding portion 5 of the wall plate 1, and the tip of the screw S is attached by a drill screw S from the protruding flat plate portion 5 side. It is preferable to fix it to the protruding flat plate portion 5 in such a form that it does not appear on the surface 3 _F of the base material 3. In this case,
As shown in (B), there is no heat bridge between the heat h _{1 of} the outside air and the drill screw S, and the heat h _{1 of} the outside air is also a heat-defective conductor base material 3
A small amount of heat h ₃ from the inner surface of the interior material 20 can be substantially blocked by the long path of the outwardly projecting flat plate portion 5 → the inclined plate portion 6 → the inwardly projecting flat plate portion 4. Therefore, not only the base material 3 can be firmly held by the drill screw S and a heavy exterior material can be fixed to the base material 3, but also an external heat insulating building in which the heat bridge from the outside air to the drill screw S is completely prevented can be obtained. Moreover, by using the small piece packing, the material cost of the base material 3 can be saved, and since the space corresponding to the thickness of the small piece packing 30 exists between the base material 3 and the outer protruding portion 5 of the wall plate, the synthetic resin foaming is performed. It facilitates filling and diffusion of the body.

The exterior material 40 is preferably provided with anchor pieces 41 and 42 at appropriate positions on the inner surface (claim 1).
5). In this case, since the anchor pieces 41 and 42 have a function of increasing the fixing force with the heat insulating material 2, the necessary fixing force can be obtained even when the adhesive force between the inner surface of the exterior material 40 and the heat insulating material 2 is relatively weak. In addition, it is preferable that the cross sections of the anchor pieces 41 and 42 be in a pull-out prevention mode (FIG. 13A). Of course, the one in which the horizontal furring shown in FIG. 1 (C) in the first invention is adopted as the anchor piece and the inner surface of the exterior material 40 is screwed with the drill screw also has the effect of increasing the adhesive force between the heat insulating material 2 and the exterior material, preferable.

Further, it is preferable that the anchor piece 41 is fixed to the outer protruding portion 5 of the wall plate 1 (claim 16). In this case, even if the solidification adhesive strength between the foamed synthetic resin material as the heat insulating material 2 and the exterior material is weak, the exterior material 40 can be securely fixed and held, so that the degree of freedom in selecting the exterior material 40 increases. Moreover, as shown in FIG. 13 (B), the anchor piece 41 fixed to the exterior material 40 forms a layer thickness of the heat insulating material 2 together with the outer protruding portion 5 of the wall plate and abuts and fixes the heat insulating material 2 on the molding die. The preparation work of is also easy. Of course, the anchor piece 41 is separated from the exterior material 40, and the wall plate, the anchor piece, and the exterior material are integrally fixed, and a packing is interposed between the anchor piece and the wall board. The person may be integrally fixed.

0 _Z and the distance between the flat plate 5 protruding outside the wall plate and the surface plate (50 m
m) is filled with urethane foam and the wall board 1
A base material 3 (wood) is embedded (FIG. 1C) on the outer surface of the base material 3 (wood) in a form in which the surface 3 _F is exposed, and is integrally molded and fixed.

Since the packing 30 is a small piece and is located only on the projecting flat plate portion 5, it does not hinder the filling of urethane foam, and the bolt holes H ₂ of the bottom plates 7 _B and 8 _B of the upper and lower frames 7 and 8 are It can also be used as an injection hole and an exhaust hole for urethane foam.
After cooling, if the mold is removed, as shown in FIG. 1 (A), in the place where the heat insulating material 2 of urethane foam is thinnest on the entire outer surface including the flat plate portion 5 of the wall plate 1 and the outer concave portion 10 _Z , Thickness W ₄ from flat plate 5 is 50 mm (base material thickness + packing thickness)
Thus, a panel wall body 10 having a flat surface and integrally fixed in a form in which the base material 3 as a horizontal furring strip is exposed and embedded only at the surface 3 _F at equal intervals on the surface is obtained. The wall 10 is shown in FIG.
As shown in (B), even if a metal vertical furring strip 16 is attached to the base material 3 with a drill screw S, heat transfer from the ventilation layer 16 to the flat plate portion 5 is h _{3 of the} wood base material 3 itself. Therefore, there is no heat bridge from the vertical furring strip 16 to the flat plate portion 5 of the wall plate.

[Use of Wall 10 (FIG. 2)] A three-story steel frame building is constructed by using the wall 10 manufactured as described above as an outer wall. That is, as shown in FIG. 2, the first floor wall body ₁ having a length L ₁ of 2770 mm is formed on a concrete foundation (first floor) whose outer periphery and underfloor are covered with a foam polyethylene heat insulating plate.
0 is tightened under the height adjustment through the bolt hole H ₂ of the lower frame 8 by the resin anchor bolt driven on the cloth foundation, and the mortar is filled between the lower frame 8 and the cloth foundation. While preventing the walls 10 from falling back and forth by a conventional temporary fixing means,
Are connected to the left and right to construct the outer peripheral wall of the building.

[Left and Right Connection of Walls] The linear left and right connection of the walls 10 is performed by the abutting lower frame bottom plate 8 _B as shown in FIG.
The grooved steel piece 25 is passed between the ends as a joint piece, and is fixed by a combination of the spot welding M and the drill screw S or either means. Of course, the bottom portions or the middle portions of the side edges 1 _E of the wall plate 1 may be connected to each other by a joining steel piece. Figure 5 shows the wall connections at the corners,
In the end bottom plate 8 _B of the lower frame 8, a groove steel piece 25 (FIG. 5 (B)) in which one end (edge) is closed with a steel plate piece 26 is spot welded M,
And / or it is fixed with a drill screw S, and the end side plate 8 _S of the other wall body abutting at a right angle is fixed with a drill screw S. Then, the synthetic resin foam heat insulating plate (5
0mm thickness, 150mm width) is attached.

After the wall surfaces connected to each other by the lower frame 8 and / or the side edges 1 _E of the wall bodies 10 are connected to each other, then along the inner surface of the upper frame 7 of each wall body. The beam receiver 12 is passed as a cross member, the upper portion of the beam receiver 12 is tightened with bolts H ₃ of the upper frame 7, and the beam receiver lower portion is inside the wall plate via a steel plate piece (not shown). The protruding flat plate portion 4 is tightened with bolts to complete the fixed fixing of the wall bodies 10 to each other (FIG. 3A).

The vertical connection of the wall body 10 is bolted through the opposing bolt holes H ₂ of the upper and lower frame bottom plates 7 _B and 8 _B of each wall body, but of course can be performed in parallel with the horizontal connection of the wall body 10. Is. The lower frame side plate 8 _S of the wall used on the second floor and above is provided with a hole H ₁ into which a reinforcing bar R is inserted so that concrete can flow in. At the corners of the wall body, both wall bodies 10 are fixed in advance by a fire-casting material (not shown) in which angle steel is assembled into a right-angled triangle, and a transversely-fixed cross-member (beam member) is fixed to the fire-casting material and It is preferable to fix it to the upper frame 7 of the wall by bolts.

As shown in FIG. 3 (A), after the wall bodies 10 are permanently fixed by the beam joists 12 to form the wall surface, the beam joists 14 are passed between the beam joists 12 on the opposite wall surfaces to form the beam joists. A beam 14 is bolted and fixed to a gusset plate 13 which is fixed in advance to 12 to form a rigid structure outer wall by the wall body 10. Next, as shown in FIG. 3 (B), a deck plate for floor concrete is stretched and fixed via the beam receiver 12 and beam 14, etc.,
A conventional reinforcing bar is provided, and a part of the concrete reinforcing bar R is inserted into the hole H ₁ of the lower frame side plate 8 _S and extended into the lower frame 8. On the rooftop floor, a concrete flow stop is provided on the upper frame 7 as shown in FIG.

FIG. 6 shows a modified example of the cross member 12. In a place where it is not necessary to support the beam 14 and only the deck plate needs to be supported and fixed, a flat steel plate deck having a width of 150 mm is used. The plate support 15 is sandwiched between the upper and lower frames 7 and 8, and the deck plate support 15 is extended inward by 50 mm, and is bolted to the upper and lower frames 7 and 8 through the bolt holes H ₂ to form the wall 1
The upper and lower parts of 0 and the left and right parts are permanently fixed. Therefore, depending on the design of the building, the cross beam receiver 12 and the deck plate receiver 15 may be used together as the horizontal members.

When concrete C is cast on the deck plate 11, the wall plate 1 serves as a concrete flow stop and the concrete fills the lower frame inner plate 8 _S , but the hole H of the side plate 8 _S is inserted into the lower frame 8. Side bar 8 because reinforcement bar R extends from _{1
The S} and bar R extension portions are integrated with the concrete to achieve a solid and rigid structure of the concrete composite floor and the wall body 10, and the load of the concrete composite floor can be smoothly applied.
Thus, the entire load of the building is surely carried by the wall body 10. Therefore, since the wall body 10 has a structure capable of withstanding the vertical stress (load) F ₁ and the horizontal stress F ₂ , it is possible to construct a structure of a steel-framed building without using conventional columns, beams, girders, and braces. It is possible.

FIG. 2 is a schematic view of a building structure. When the outer wall of a steel frame building is constructed by the wall body 10 of this embodiment, the outer surface of the building is completely covered with a heat insulating material from the foundation to the roof. External insulation can be achieved by simply connecting and standing the uniform wall bodies 10 that are factory-produced as standard products. Also, for the outer wall finish, the exterior material (siding) is directly attached to the horizontal furring strip of the base material 3 embedded in the wall body 10, or the ventilation layer 9 is provided on the horizontal furring strip 3 via the vertical furring strip 16 (FIG. 8). All you have to do is form and attach. Moreover, as shown in FIG. 8B, since the base material 3 is wood and the drill screw S from the protruding flat plate portion 5 does not protrude to the base material surface 3 _F , the metal vertical furring strip 1
Even if 6 is adopted, a thermal bridge from the vertical furring strip 16 to the wall plate 1 does not occur at all.

Further, when finishing the interior, the recess 10 _{Z on} the inner surface of the wall 10 can be used as a space for filling the sound absorbing and heat insulating material G such as glass wool, and also as a space for facility piping and wiring. Then, the inner surface recess 10 _Z of the wall body 10
If the sound absorbing heat insulating material is filled in, the heat insulating function of the thin heat insulating material portion (the portion on the outer protruding flat plate portion 5) on the opposite outer surface is suitably complemented. Further, an interior material such as a gypsum board may be attached with a drill screw using the protruding flat plate portion 4 inside the wall plate of the wall body as a base material. Moreover, since the group of protruding flat plate portions 4 is arranged in an integral fraction of the market size of the building material, it is easy to determine the mounting position and the mounting work is easy.

Therefore, if the wall body 10 of this embodiment is adopted as the outer wall material, a steel-framed building without pillars, beams, girders, braces, etc. can be constructed, and the steel material used in the building is much more extreme than the conventional steel-framed building. In addition to saving (about 1/3), it is also advantageous in terms of foundation work for ground bearing measures to reduce the weight of the building, and it is possible to reduce construction costs. Also on the floor plan of the building,
Freedom is increased because there are no restrictions due to the column arrangement. Further, since the wall body 10 is a factory-produced product, it can be manufactured and stored at all times and can be used for transportation when necessary, and the building management system from the design of the building to the completion of construction can be rationalized.

Moreover, in the wall body 10, the projecting flat plate portion 4 has a function as a base material for mounting the interior material on the inner surface, and the recess 10 _Z has a space for filling the sound absorbing and heat insulating material and for facility piping and wiring. ,
Having the heat insulating material 2 provided with the base material 3 on the outer surface, it is possible to reduce the types of building materials to be carried in on the site and the number of construction man-hours, and it is possible to shorten the construction period of the outer heat insulating steel frame building and save the labor of the construction. . Of course, since the wall body 10 is a wall panel of the size of the building material market, it can be widely used as a wall material for external heat insulation in new construction of various buildings and even in the remodeling of buildings.

[First Invention Example 2 (FIGS. 9 and 10)] Vertical walls are provided on both sides of the wall body 10 of Example 1. That is, as shown in FIG. 9B, the length of the vertical frame 24 is L ₁ having the same length as that of the wall plate 1, the width of the side plate 24 _S is the same width W _{2 as the} upper and lower frames 7, 8, and the bent portion 24. width _B is 50 mm, angle iron of the same 2.3mm wall thickness with upper and lower frames 7,8 a (angle steel) material, respectively, the bent portion 24 _B upper and lower ends upper and lower frames side plate 7 _S, 8 _S and shock A notch 24 _C for mating is formed, and the side plate 24 _S is provided with four bolt holes H ₅ . The vertical frame 24 is attached to the wall body by attaching the bent portion 24 _B to the side end 1 _E of the wall plate 1 before applying the heat insulating material.
Abuts against the outer side, is fixed by spot welding and a bent portion 24 _B and the side edge 1 _E in a form collides vertically frame side plate 7 _S, 8 _S by the notch 24 _C.

Then, the heat insulating material 2 and the base material 3 are applied in the same manner as in Example 1 to form the wall body 10 of FIG. 9 (A). Since the obtained wall body 10 has the vertical frame side plates 24 _{S on} both side surfaces, when connecting the wall bodies 10 to each other left and right, as shown in FIG.
As shown in, tacking is facilitated by bolts fastening through the bolt holes H ₅ of the side plate 24 _S, the steel sheet becomes strong tightening if interposed as packing between the side plates 24 _S. Moreover, while the overlapping portion of the wall plate side end 1 _E and the bent portion 24 _B exerts a reinforcing effect, the presence of the vertical frame side plate 24 _S causes the lower frame 8 to be linearly connected as in Example 1 (FIG. 4). And the corner connection (FIG. 5) cannot be performed, but the other effects are similar to those of the wall body of Example 1, and the intended problem of the invention can be solved.

[First Invention Example 3 (FIG. 11)] Example 1 (FIG. 1)
While the wall body 10 of FIG. 3 fits the wall plate 1 into the upper and lower frame bodies 7 and 8, the wall body 10 of Example 3 fits the upper and lower frame bodies 7 and 8 into the wall plate 1. That is, as shown in FIG. 11 (B), the frame side plates 7 _S , 8 _{S are} fitted from the upper and lower ends of the wall plate into the roots of the inclined plate parts 6 close to the inner and outer protruding flat plate parts 4, 5 of the wall plate 1. Forming a slit 6'having a width W ₇ and a depth L ₇ for the upper and lower frames 7,
8, the side plates 7 _S , 8 _S are fitted into the wall plates by fitting them into the slits 6 ′, and the wall plate ends are inscribed in the frame bottom plates 7 _B , 8 _B. Spot welding is applied to the overlapping portions of the frames 4 and 5 and the frame side plates 7 _S and 8 _S (Fig. 11 (A)).
Next, the same heat insulating material as in Example 1 is applied to the wall body. It should be noted that each corner Ca (FIG. 11C) of the upper and lower frame bodies 7 and 8 should be ground and rounded before fitting so that the entire length of the wall plate is brought into contact with the upper and lower frame bottom plates to reduce the load. Necessary for prompt transmission to the foundation.

In the obtained wall body, the inside projecting flat plate portion 4 of the wall plate 1 occupies the exposed position inside the inner plates 7 _S , 8 _S of the upper and lower frames 7, 8 on the inside. Upper and lower side plates 7 such as wall 1
_Since there is no protrusion of _S , 8 _S , it is advantageous in that the inner protruding flat plate portion 4 can be used as a base material and an interior plate such as a gypsum board can be flatly attached from top to bottom without a step. The same effect as that of the wall body is achieved, and the intended problem of the invention can be solved.

[Second Invention (FIGS. 12 and 13)] The structure of the wall plate 1 is the same as that of the first invention. Of course, the wall body 10 'can be manufactured in the same manner as in Example 1, Example 2 and Example 3 of the first invention with respect to the steel frame body structure including the wall plate 1 and the upper and lower frames 7 and 8 before the heat insulating material is applied. Then, in the heat insulating material filling and applying step, as shown in FIG.
1 over the entire length of the inner surface and at equal intervals, the siding (wall plate) arranged and fixed with the drill screw S is arranged in the frame as the exterior material 40, and the urethane foam foam coagulated in the same manner as in the first invention example 1 is solidified. By the adhesive force, the entire inner side surface including the anchor piece peripheral surface of the exterior member 40, the heat insulating material 2 and the entire outer side surface of the wall plate 1 are integrally fixed by the interfacial adhesive force to obtain a wall body 10 'as shown in FIG. . Of course, since the urethane foam has a large solidification adhesive strength to a metal plate, a synthetic resin plate, a wooden board, etc., as long as it is lightweight and has good adhesiveness, the exterior surface material has a sufficient adhesive force without using the anchor piece 41. Is obtained.

The obtained wall body 10 'is the wall body 10 of the first invention.
In the same way as the above, it can be used as a structural wall body of a steel building, and in the construction of the building structure such as the connection of the wall bodies 10 ′, the formation of a concrete composite floor, the wall body 10 ′ of the second invention is 1
It has the same function as the wall 10 of the invention. Moreover, since the outer wall constructed by the wall body 10 'of the second invention has the exterior material provided at the time of manufacturing the panel wall body in the factory, it is no longer necessary to apply the wall material such as siding at the construction site. In addition to being unnecessary, a more accurate and uniform exterior material will be provided than the exterior material attached by on-site construction, and when constructing a steel frame building, it is even more effective than when the wall body 10 of the first invention is used. Rationalization and efficiency of construction can be achieved.

[Others] As the base material 3, a conventional furring material such as wood, steel, and vinyl chloride synthetic resin can be used, and the cross-sectional shape is not limited to the trapezoid, and the cross-section may be a U-shape, an E-shape, or an inner surface. It is effective to use a flat plate or the like having a stop projection, which can be easily embedded in the heat insulating material and can be prevented from being pulled out. Therefore, a light exterior material such as siding can be held by the base material simply embedded in the heat insulating material layer.

If side plates are formed by bending the wall plate 1 on both side surfaces of the wall body 10, the side plates have the same function as the vertical frame 24 in the invention of claim 10. Further, in the invention of claim 6, if the width of the inner protruding flat plate portion 4 is made larger than the width of the outer protruding flat plate portion 5, it is advantageous to use the inner protruding flat plate portion 4 as a base material for interior. And moreover,
There is no particular problem in mounting the furring strip of the base material on the outwardly projecting flat plate portion 5, and there is no problem in the strength of the wall plate 1 against the vertical stress F ₁ and the horizontal stress F ₂ .

Further, as shown in FIG. 13 (B), the exterior material 40 is a structural plywood board having an anchor piece 41 previously bonded or screwed to the back surface thereof, and the anchor piece is fixed from the wall board side to form a synthetic resin foam. If you integrally fix it with the foam coagulation adhesive force of the body,
The fixing force of the exterior material 40 becomes strong, and the exterior finish of ceramic tiles is also possible. Further, as shown in FIG. 13C, if the field edge 42 used for the lightweight steel ceiling is diverted and the drill screw S is fixed to the inner surface of the exterior material and used as the anchor piece 42, a strong anchor function for the heat insulating material 2 is achieved. Therefore, it is possible to use an exterior material having a weak adhesive force with the heat insulating material 2.

[0060]

[Effect of the first invention] Since the wall body 10 has strength to withstand the vertical stress F ₁ transmitted from the floor of the building to the wall body and the horizontal stress F ₂ acting on the wall surface, columns, beams, girders, braces, etc. The building can be constructed without the need for a building, and a building with an increased degree of freedom in floor plan without restrictions due to the column arrangement can be obtained. Moreover, since the steel used in the wall is a thin steel plate, the wall itself becomes light weight, and it becomes a lightweight building that saves the used steel, which is advantageous from the viewpoint of steel usage and from the viewpoint of the foundation strength of the building. .

Furthermore, since the wall 10 is a factory-produced panel integrally provided with the layer of the heat insulating material 2 and the base material 3 for exterior, it is advantageous as a standardized homogeneous product for storage and transportation, and it is seasonal. Because it can be produced regardless of the busy period,
The management system from building design to completion can be rationalized. Further, unlike the conventional case, since heavy building materials such as columns, beams and girders are not used, it is easy to carry the building materials to the site, and the wallboard itself inside the wall body 10 is used as a base material for interior. What can be done, since the wall 10 itself is integrally provided with the layer of the heat insulating material 2 and the base material 3 for exterior, the type of building material used on the site and the number of construction steps are reduced, and high quality with a high factory production ratio, Moreover, a homogeneous building can be constructed in a short construction period, and the building can be reasonably constructed at a low cost.

Further, the wall body 10 has a high airtightness due to the laminated structure of the wall plate 1 made of one thin steel plate and the layer of the heat insulating material 2, and the inner surface is filled with the sound absorbing heat insulating material G and the equipment. since the possible recess 10 _Z of the pipe is present, I heat insulator 2 layer coupled with an outer surface, is easy to construction equipment, that Do facilitates building high performance building to heat and sound. Moreover, the exterior base material 3 is the heat insulating material 2.
Since it is buried inside, the exterior material (siding) can be attached to the base material 3 without generating a heat bridge, and the construction of the outer heat-insulated steel frame building excellent in the living environment becomes easy.

[0063]

[Effect of the second invention] Both the second invention (the invention in which the exterior material 40 is fixed to the outer surface of the heat insulating material 2) and the first invention (the invention in which the base material 3 is buried and exposed on the outer surface of the heat insulating material 2) are steel-framed buildings. The same structural material has the same effect and the same effect. Moreover, since the second invention is a panel wall body 10 'in which an exterior material is integrated, in the construction of a steel frame building using the wall body 10' of the second invention, Even installation work can be omitted, and the number of on-site work steps can be further reduced and the on-site work can be more rationalized than the construction work by using the wall body 10 of the first invention. Moreover, in the panel wall body 10 'manufactured as a factory-produced product, the mounting accuracy of the exterior material is more uniform and higher than that of the exterior material installed by the on-site construction.
