Hereinafter, an embodiment of the present invention will be described with reference to the illustrated examples. FIGS. 1 to 11 relate to the first invention of the present application, and FIG. 1 shows that the building structure 1A of the first invention is a large space building. _λ

 Four

FIG. 2 is a perspective view conceptually illustrating a case where the gymnasium is formed as a physical object, FIG. 2 is a perspective view showing a floor portion of a second floor portion of the building structure 1 、, and FIG. 8 is a perspective view showing a roof portion. . FIGS. 12 to 31 are diagrams illustrating a building structure according to the second invention of the present application. FIGS. 12 and 13 are a diagram illustrating the outer wall portion and a front view.

 In FIG. 1, a building structure 1A of the first invention is, in this example, a two-story gymnasium having an arched roof portion 7, and a surface formed by sequentially connecting bent building members 2. It comprises upper and lower building frames 4 U, 4 L having a base 3 in the form of a bar.

 Then, a first surface structure S1, which is a floor portion 6 of the second floor, is formed by using the lower building frame 4L, and a roof portion is formed by using the upper building frame 4U. 7, the second planar structure S2 is formed.

 The floor 6 is supported by a frame (not shown) including, for example, a pillar standing upright along the outer wall W and a horizontal beam connecting the pillars. A floor material 9A (shown in FIGS. 2 and 3) is attached to the lower building frame 4L via a floor base plate 8A.

 Further, as shown in FIGS. 2 and 3, the lower building frame 4L is, in this example, a base 3 made of a bent building member 2 and fixed to the upper surface of the base 3 to secure the base 3. It is formed from a holding frame material 10 for shaping.

 Here, as shown in FIG. 3 in an enlarged manner, the bent architectural member 2 is connected to a horizontal frame 11 and an end of the horizontal frame 11 via an arc 12 and A series of vertical frame portions 13 that are bent at substantially right angles to the horizontal frame portion 11 are provided. In the present example, a case is shown in which the vertical frame portion 13 is provided at both ends of the horizontal frame portion 11 to form a substantially U-shape.

In this example, the bent architectural member 2 is made of a flat-plate-like wooden material having a rectangular cross section, and its wide side faces inward and outward in the radial direction of the bending, and the wood fibers are curved in the length direction. The arc portion 12 is formed by bending as described above. As the wood material, besides solid wood as in this example, glued wood, laminated wood and the like can be suitably used, but other materials such as synthetic resin materials and metal materials can be used as required. . „

The “substantially right-angled shape” means that when the vertical frame portions 13 are connected to each other back to back as shown in FIGS. 7 (A) to 7 (D), Mean that the vertical frame portion 13 is orthogonal to the horizontal frame portion connection line L formed by connecting the series. At this time, the horizontal frame connecting line L is a straight line (Fig. 7 (A)), an arc-shaped curve (Fig. 7 (B)), or a zigzag line such as a wavy shape (Fig. 7 (C), (D)). In the case of a zigzag line, it is orthogonal to the center N of the zigzag.

 In the bent building member 2, when the floor portion 6 is formed, the horizontal frame portion 11 is preferably formed in a straight line as in this example. It can also be formed in an arc shape with a large radius of curvature R as shown in FIG. The “arc shape having a large radius of curvature R” means an arc having a radius of curvature R of 2.5 times or more the radius of curvature r of the arc portion 12.

 Then, the base 3 is formed in a planar shape by connecting such bent architectural members 2 to each other. That is, the base portion 3 is formed by using the connecting portion P including the multi-plane connecting portion P 1 in which at least the vertical frame portions 13 face and join on three or more surfaces. Are sequentially combined. As a result, in the base 3, the horizontal frame portions 11 are connected to each other, and the coupling portions P project downward.

 In this example, a case where the horizontal frame portions 11 are connected in a grid pattern is illustrated. In such a case, as shown in FIG. 4 (A), the multi-plane connecting portion P 1 is formed by connecting a vertical frame portion 13 with four sides facing each other to form a cross which constitutes a main portion of the base portion 3. As shown in Fig. 4 (B), the T-shaped three-sided connecting part P1 that forms the side edge of the base 3 by joining the three sides facing each other as shown in Fig. 4 (B). b. In addition, as shown in FIG. 4 (C), as the connecting portion P, in addition to the multi-surface connecting portion P1, the corner portion of the base portion 3 is formed by joining the vertical frame portions 13 facing each other on two surfaces. It may include an L-shaped two-sided connecting portion P2.

At this time, in the present example, at the joint portion P, a living material 15 is interposed between a plurality of vertical frame portions 13 facing each other, thereby stabilizing the space between the vertical frame portions 13. And are firmly joined. However, as shown in FIGS. 5 (A) and 5 (B), the vertical frame portions 13 may be directly joined without intervening the livestock material 15. This connection means b

In this example, the case where a fastening bracket 16 such as a port nut is used is illustrated. For example, various dovetail joints for fitting a dove tenon with a dovetail groove (including a dovetail hole) are used. Etc. can be appropriately adopted.

 Here, the bent architectural member 2 can exhibit an excellent elasticity function by the arc portion 12, and as shown in FIG. 3, absorbs an external force F (load, vibration, etc.) that acts on the bent architectural member 2. The direction can be changed, and it can be successively transmitted to adjacent bent architectural members 2 and dispersed. Therefore, in the base 3 formed by the bent building member 2, when a destructive movement (for example, vibration) is locally generated, the movement is caused by the bent building member connected at the joint P. As a result, they are dispersed in four directions while being attenuated sequentially by the elastic function (2). In addition, even when the entire base 3 is moved, all the bent architectural members 2 simultaneously exert the elastic function, and the resistance is attenuated individually by the resistance.

 Therefore, even when the base 3 is large and its support span is long, destruction due to load, impact, vibration, or the like can be effectively suppressed, and the durability can be greatly increased. Furthermore, since wood materials can be used, the increase in weight can be kept low, and the burden on pillars can be reduced, which contributes to the improvement of the durability of the entire building structure.

 In this example, the base 3 constituting the floor 6 also constitutes the ceiling of the first floor. At this time, since the bent building members 2 are connected to each other in a lattice shape, the base portion 3 can finish the ceiling portion in a ceiling-like pattern, which also helps to improve the appearance.

 Further, as shown in FIG. 2, the holding frame member 10 for holding the base portion 3 is a base frame formed by bending the bar member 10A and joining it in a lattice shape along the building member 2, and By fixing the horizontal frame portion 11 on the surface (in this example, the upper surface) on the side opposite to the joint portion P, the base portion 3 is maintained. In this example, the floor base plate 8A and the floor material 9A are sequentially provided on the holding frame material 10; however, the base 3 and the underfloor base plate 8 are not inserted through the holding frame material 10. A can be fixed directly.

6 (A) and 6 (B) show another embodiment of the bent building member 2. FIG. _n

The bent architectural member 2 is formed in a ring shape in which the upper and lower horizontal frame portions 11 U and 11 L are connected to each other by a vertical frame portion 13 through an arc portion 12 between both ends. In FIG. 6 (A), the vertical frames 13 are connected sequentially through the housing material 15, and in FIG. 6 (B), the vertical frames 13 are directly connected. This is exemplified. In the case of such a ring shape, it is also possible to attach the ceiling plate 17 to the lower horizontal frame portion 11 L and to cover the base portion 3.

 Next, the roof 7 will be described. As shown in Figs. 8 and 9, the roof 7 is provided with a roofing material 9B via a roof base plate 8B on the upper surface of the upper building frame 4U supported by the frame structure. It is formed by being attached. Further, the upper building frame 4U has a base 3 held by the holding frame member 10, like the above-described building frame 4L.

 Here, the point different from the lower building frame 4L is that, in this example, the base 3 of the upper building frame 4U includes a building A in order to form the arched roof portion 7. (Shown in Fig. 1) In the direction J1, which is a square building, the first bent building member 2A with the horizontal frame 11 straight as in Fig. 3 is used as in Fig. 3 and at right angles to the building A In the wife direction J2, as shown in FIG. 9, a second bent architectural member 2B in which the horizontal frame portion 11 is curved in an arc along the arched curve of the roof portion 7 is provided. Used. As a matter of course, as the first bent building member 2A, as shown in FIG. 7 (C), the horizontal frame is connected so that the center N of the zigzag at the horizontal frame connecting line L becomes a straight line. A structure in which the part 11 is curved may be employed. As the second bent architectural member 2B, as shown in Fig. 7- (D), the zigzag center N of the horizontal frame connecting line L should be an arc along the arched curve of the roof 7. Alternatively, a structure in which the horizontal frame portion 11 is curved may be adopted. Then, the first and second bent building members 2A and 2B are vertically connected to each other by using the connecting portion P, thereby forming the arch-shaped base portion 3. Has formed. By using the base 3 having substantially the same configuration as the lower building frame 4 L, the roof 7 can be formed in a horizontal plane or an inclined plane. It is possible to construct various roofs such as a ridge roof.

Also, in FIG. 10, similarly to FIG. 6, the second bent architectural member 2B is formed in a ring shape. _g

FIG. When the base 3 is formed only of the second bent building member 2B, the roof 7 can be formed in a circular dome shape, for example, as shown in FIG.

 Next, the building structure 1B of the second invention will be described with reference to FIGS.

 In FIG. 12, the building structure 1 B of the second invention is a rectangular building whose four surfaces are surrounded by a wall portion 20 for forming an outer wall, and a surface forming the wall portion 20. As shown in FIG. 13, at least one of the structural members SW, in this example, the four surface structural members SW are connected to the bent building members 22A and 22B (when collectively referred to as bent building members 2A and 2B). 2) are formed by using a building frame 26 W on the planar side joined to each other.

The building frame 26 W on this side is supported by a frame including, for example, a column 40 erecting along the outer wall and a horizontal beam 39 connecting the columns 40. You. An external wall material (not shown) or the like is attached to the building frame 26 W on the side via a base plate or directly, so that the surface structure SW (wall body portion 20) is formed. It is formed. Here, as shown in FIGS. 14 (a) and 14 (b), the bent building members 22A and 22B have a straight horizontal frame 31a and a horizontal frame 31a. The end of 31a is connected to the end of 3a via an arc portion 32 having a relatively large radius r, and is provided with a series of the horizontal frame portion 31a and the bent vertical linear frame portion 31b. In this example, the horizontal and vertical frame portions 31a and 31b (referred to collectively as frame portions 31) bend at right angles to each other, that is, the arc portion 32 has a central angle Θ of 90 °-1 da 4 an arc, moreover arc ^songs: with respect to the center line C passing through the center, the outward surface 3 1 S is exemplified a case that forms a parallel. Among these, the bent building member 22A has the same leg shape as the frame portions 31a and 31b are relatively short and the same size, and the bent building member 22B is One frame 31b has an L-shape that is longer than the other frame 31a.

 Note that the bent building member 22 is formed by folding a flat-plate-like wooden material having a rectangular cross section in the same manner as the bent building member 2 used in the first invention so that the wood fibers are curved in the length direction. It is formed by bending.

In this example, a ring-shaped body 25 (shown in FIG. 13) is formed using such a bent architectural member 22, and an outward facing surface 31 S of the ring-shaped body 25 is formed as follows. Height _Q

They are joined to each other as a centering mating surface S. Thus, the building frame 26W on the side having the planar base 27 to which the frame 31 is continuous is formed. At this time, the connecting portion P, which is the two-side connecting portion P2 where the joining surfaces S and S are joined, is aligned without protruding in the same plane as the base portion 27, unlike the first invention.

 Specifically, as shown in a rectangular ring-shaped body 25 at the upper left of FIG. 13, the L-shaped bent building member 22 B is arranged at diagonal corners cl and c 3, and In the diagonal corners c2 and c4 of this, equiangular bent building members 22A are arranged. As a result, a rectangular ring-shaped body 25A1 whose four sides are surrounded by vertical and horizontal ring pieces having seams a1, a2, a3, and a4 is formed.

 Further, in this example, the ring-shaped body 25 A 1 is composed of an upper beam 39, a left column 40, a right ring 25 A 2, and a lower ring 25 B By combining with 1, a strong rectangular ring-shaped body 25 A 1 is formed. In some cases, members such as pillars and beams are not used, and only the surrounding ring-shaped body 25 such as the ring-shaped body 25 B 2 adjacent to the lower ring-shaped body 25 B 1 is used. May be combined with

Here, in order to strengthen the connection between the ring-shaped members 25, as shown in FIG. 13, one of the ring-shaped members in the vertical ring pieces facing the adjacent ring-shaped members 25, 25. The seam a4 of the body 25A1 is displaced vertically, such as by positioning the seam a2 of the other ring-shaped body 25A2. Also, the seam a3 and the seam a1 are displaced from each other on the horizontal ring pieces facing the upper and lower ring-shaped members 2 5 ₇ 2 5-. This prevents the seams a, a from breaking due to overlapping or from decreasing in strength due to approaching seams. For this purpose, the seams a and a are preferably separated from each other by about 1 Z 5 to 12 of the length of the vertical and horizontal ring pieces.

As described above, in the second invention, similarly to the first invention, the arcuate portion 32 exhibits an elastic function, and absorbs an external force acting in the in-plane direction while adjoining the bent building member 22 adjacent thereto. It can be transmitted and dispersed sequentially, and it is possible to improve earthquake resistance and shock absorption. Furthermore, each ring piece of each ring-shaped body 25 is joined to an adjacent member (including a ring piece, a beam member 39, and a column 40) to form a building frame 26W on the side. for, In this example, as shown in FIGS. 16 to 18, dovetail connection is adopted.

 In this dovetail connection, of the outwardly facing surfaces 31 S of the linear frame portions 31 a and 31 b, a surface portion in contact with the adjacent member is defined as a mating surface S. Then, the dovetail grooves 42 extending in the longitudinal direction are formed facing each other on both mating surfaces S which are in contact with each other (note that the dovetail grooves 42 are omitted in FIGS. 14 and 15). . The dovetail groove 42 has a widened portion 41 (shown in FIG. 18) in which the groove width increases toward the groove bottom.

 Also, in this dovetail groove 42, an ant tenon 44 smaller than the minimum width of the dovetail groove 42 and divided in the width direction is inserted. The dovetail tenon 44 has a thickness that straddles the facing mating surfaces S, S (preferably in contact with the bottom of each groove), and has a cross-sectional shape of a dovetail that matches the widened portion 41. Butterfly shape provided on both sides.

 After inserting this dovetail tenon 44 into at least one dovetail groove 42 of the bent building member 22 and mating the other bent building member 22, as shown in FIG. Divide the ant tenon material 4 4 using the driving tool 4 5 inserted from the mating plane and expand it to the width method. Thus, the dovetail-shaped portion is closely fitted to the widened portion 41, and the two are joined. The dovetail groove 42 can be easily formed using a so-called dovetail milling machine.

 In this example, such a dovetail joint is, as illustrated in FIG. 16, a region y 1 from the top to the upper seam a 4 and a region y 2 from the seam a 4 to the lower seam a 2. , And an area y-3 below the seam a2. In addition, by making the lengths of the dovetail groove 42 and the dovetail tenon 44 the same, it is possible to prevent the relative positional displacement of the bent architectural members 22A and 22B in the axial direction, while using the joint a. Can be firmly bonded without breaking. In addition, despite the dovetail connection, the two bent construction members 22 can be easily connected without relatively moving the members in the axial direction, or without inserting the dovetail 24 in the axial direction.

In the embodiment shown in FIGS. 12 and 13, the building frame 26 W on the side where a plurality of ring-shaped bodies 25 are formed in parallel between the pillars 40 and the like is used as the pillar body 40. By sequentially arranging the building frames 26 W on the other side at right angles through the like, a building structure 1 B having a rectangular outer wall is formed as shown in FIG. In the building structure 1B U

The roof part according to the first invention or the roof part having a conventional structure can be provided on the beam member 39 further above.

 In addition, such a dovetail connection is not limited to the connection between bent building members or between this bent building member and straight building members such as columns and beams. It can be suitably used for connecting between mating surfaces of various building members.

 Further, as the driving tool 45 of the dovetail connection, in addition to the pin-shaped body, a flat-plate-shaped one extending in a tenon direction (shown in FIG. 19) can also be used. As shown in Fig. 20, a screw-shaped one with a mortise pin 46b at the head 46a of the outer peripheral screw can also be used. 4 4 can be disassembled by widening and screwing back.

 Further, as shown in FIG. 21, various connecting means using porting nuts, screws, nails, and other fixing tools 48, adhesives, etc. are used together with the dovetail joint or instead of the dovetail joint. Can be adopted. In the region y2 (shown in FIG. 16), it is preferable to use these fasteners 48 to reliably prevent longitudinal displacement.

 In addition, instead of the bent building members 22A and 22B, as shown in FIG. 14 (c), arc-shaped portions 32 and 32 are provided on both sides of a linear vertical frame 31b. U-shaped bent architectural member 22C provided with straight short-sided horizontal frame portions 31a and 31a can be used, and by combining two of them, the rectangular shape can be obtained. Thus, a ring-shaped body 2-5 can be formed.

 Further, FIGS. 22 to 24 show another embodiment of the side frame 26 W (wall portion 20).

FIGS. 22 (a) and 23 show that the rectangular ring-shaped body 25 is connected to the architectural frame 26 on the arc-shaped side as shown in FIG. 22 (a). W is formed, and the building frame 26 W is connected to form a building structure 1Ba having a circular cage-shaped outer wall as shown in FIG. Also, by partially using it, the corner of the rectangular parallelepiped building structure 1B shown in FIG. 12 can be formed in an arc shape. To form such an arched architectural frame 26 W, for example, see FIG. 15 (a) ^

As shown in Fig. 7, a ring-shaped body 25 is formed by using a bent building member 22D in which only the frame portions 31a located on the upper side and the lower side are curved in an arc shape with a radius R.

 Further, FIG. 22 (b) exemplifies a building frame 26W which is bent in a polygonal shape along an arc surface. As shown in Fig. 15 (b), this building frame 26W is configured such that only the horizontal frame portion 31a located on the upper side and the lower side is moved with respect to the vertical vertical frame portion 31b. It can be formed by using a bent architectural member 22E twisted at an angular rate in a horizontal plane. As another method, the bent building member 22A, 22B or 22C is used, and the interposed member 47 having a tapered slope as shown in FIG. By interposing between 3 1 b, the building frame 26 W shown in FIG. 22 (b) can be formed. Note that the intervening member 47 can be a short dimension provided only at the connection site.

 FIG. 25 illustrates an embodiment in which the building frame 26W gradually tilts inward or outward upward. In this case, as shown in FIG. 15 (d), for example, in the lateral frame portion 31a located on the upper side and the lower side, the outward facing surface 31S is positioned at the bending center of the arc portion 32. A bent building member 22G inclined at an angle β to the passing center line C is used. In addition to using the bent building member 22 Α, 22 Β, or 22 C, as shown in FIG. 26, the intervening member 47 is placed between the horizontal frame portions 31 a. By intervening, it is possible to form a cam-shaped architectural structure or an arch-shaped roof portion 7 in which the construction frame 26 W is inclined inward upward. -.

Fig. 27 shows a part of the construction frame 26W, which is a regular 12-hedron building structure shown in Fig. 28, developed on a plane. For convenience, the arc portion 25 is omitted. In such a case, as shown in Fig. 15 (e), long and short frames 31a and 3lb are provided via an arc 32 having a sandwiching angle 0 of 108 °. a, a 3 lb outward facing surface 31S, a pyramidal outer surface bent architectural member 2 inclined at an angle iS with respect to a center line C passing through the bending center of the arc portion 32 Use 2H. Then, these are combined to form a regular pentagonal ring-shaped body 25 as shown in FIG. 27, and the ring-shaped bodies 25 are connected to each other. As a result, a building structure 1 B consisting of a regular 12 dihedral building frame 26 W with an outer wall and a roof ^

b.

 In addition, it is also possible to configure by interposing the intervening member 47, and further, as shown in FIG. 15 (f), a bent architectural member having a trapezoidal cross section in which one wide surface is a slope in the cross section. By using 22 I, a ring-shaped body 25 having all the outward faces 31 S inclined with respect to the center line C can be formed.

 Furthermore, as shown in Fig. 15 (g), there are three or more circular arc portions 32, or various shapes such as bent architectural members 2 2 J having angles 6>, a, and / 3 changed. By using curved architectural members 22, the oblique truncated cubic octahedron (upper half) shown in Fig. 29, the delta 20 helical body shown in Fig. 30 and the cubic octahedron shown in Fig. 31 (half) ), And furthermore, a building structure 1 Bc to 1 Be composed of a building frame 26 W of various three-dimensional shapes such as a spherical shell such as a circle, an ellipse, or a fan.

 In the polyhedron shown in Figs. 27 to 31, etc., each face is divided into a plurality of faces, and the faces are formed by a ring-shaped body such as a triangular shape or a rectangular shape using a bent architectural member 22. You can also. In such a case, each surface is formed by the architectural frame body 26W formed by joining the ring-shaped bodies that are the divided surface portions.

 Although the preferred embodiment of the present invention has been described in detail, the building structure of the present invention is not limited to a large space building, and may be formed as an ordinary house or the like. The present invention can be implemented in various modes.

 According to the present invention as described above, for example, a surface structure such as a roof, a ceiling, a floor, and a wall can be formed in a large size while suppressing an increase in weight. In addition, when a load is applied, the surface structure can disperse and reduce the stress by its elastic function. Even when the surface structure is large and its support span is long, the surface structure can be out-of-plane direction or plane. Deformation and impact due to inward load can be kept low, breakage and damage can be prevented, and durable strength can be increased.

Furthermore, when the architectural frame is exposed as a ceiling, etc., it is possible to obtain a beautiful geometric shape and a ceiling-like pattern, and when the architectural frame is used as an outer wall, a building structure is obtained. It can greatly contribute to the improvement of appearance performance, for example, it can be formed in a free three-dimensional shape. ^

Industrial applicability

 As described above, according to the present invention, a surface structure suitable for a roof, a ceiling, a floor, a wall, or the like can be formed in a large size while suppressing an increase in weight, and the surface structure has elasticity. Excessive load, such as adding functions, can be absorbed by its elastic deformation, and the seismic resistance and absorption of building structures can be improved.
