Description

Construction Structure, Structural Unit and Construction Method {CONSTRUCTION STRUCTURE BODY, STRUCTURE UNIT, AND METHOD FOR THE UNIT}

The present invention relates to an architectural structure constructed by connecting a plurality of structural units to each other, particularly an architectural structure having a honeycomb-shaped main frame extending in a plane shape using a hexagonal grid as a unit grid. It also relates to the structural unit and the construction method of the building structure using the same.

Conventionally, various construction methods are known which construct structural spheres using structural units made of precast concrete members.

Patent Literature 1 discloses a precast concrete member and a joining method thereof for joining a triangular unit lattice to be used in a building structure having a dome shape. The building structure of patent document 1 has 6 edges branching radially centering on each vertex of a triangular grid. As a precast concrete member for constructing this structure, a flat hexagonal joint member located at the center and six columnar members joined to six side surfaces of the joint member are used. Each columnar member has a large diameter portion at both ends and inserts PC steel from the shoulder portion of the large diameter portion of one columnar member and passes through the joining member to pass through to the shoulder portion of the opposing columnar member. Tension is introduced to fix and bond. In the case of even-numbered radially branched columnar members, they are thus joined.

8 and 9 of Patent Document 1 also disclose a method of joining three (that is, odd) columnar members to an almost triangular joining member side, wherein a fixing part and a PC steel are embedded in the joining member. By protruding the tip of the PC steel, it is passed through the large diameter portion of the columnar member, and the post tension is introduced to fix it.

In Patent Document 2, a three-pronged column for making a hexagonal structure of a structural pillar of a building or an elevated bridge is disclosed. These three-pronged pillars are joined to three girder pillars extending downward in a slope to the lower ends of hexagonal posts arranged vertically. By sequentially connecting the upper end of the hexagonal posts and the lower ends of the three girder pillars, as shown in the plan view of FIG. 4 of Patent Document 2, a structure that looks like a hexagonal lattice is formed when viewed from above.

On the other hand, conventionally, high-rise or ultra-high-rise building structures were generally pure ramen furniture in which vertical columns and horizontal girders were combined in a three-dimensional lattice shape. There were many drawbacks to this. On the other hand, the tube furniture composed of columns arranged continuously on the outer periphery of the building and the girders connecting it has an advantage in that there is a large degree of freedom in design because it can secure a space without pillars or girders inside. In addition, since the whole building is deformed into a tube shape, it is also excellent in shock resistance and wind pressure resistance.

In addition, conventionally, a structure having a honeycomb shape in which a unit grid is a hexagonal grid and connected in a repeating pattern is known to be rigid and is used as various points or building members of buildings (Patent Documents 1, 3, 4, etc.). As an example applied to a honeycomb-shaped tube furniture, Patent Document 5 discloses a structure in which a hexagonal lattice is connected in a horizontal plane and further laminated via a vertical column in the vertical direction.

As another example applied to honeycomb-shaped tube furniture, Patent Document 6 uses a column-shaped formwork element having a hexagonal cross section made of precast concrete, and assembles a wall having a honeycomb-shaped horizontal cross section by contacting the outer surfaces thereof. And a pier structure constructed by repeatedly pouring concrete in a columnar space surrounded by a wall and extending upward.

In addition, patent documents 7-8 are cited in the international search report of the international patent application PCT / JP2006 / 316868 on which the priority claim of this application is based. Patent document 7 combines the panels so that they can freely swing between hinges formed at the top of a triangular panel unit, and joins a plurality of panel units on a plane, and then hangs them up or pushes them up to form a dome shape. Disclosed is a structure to make. Patent Document 8 discloses a wall structure in which panel units having a rectangular shape rather than a hexagon are joined together by a tension member. Patent document 9 discloses a dome structure in which a hexagonal or pentagonal panel is combined.

Problems to be Solved by the Invention

The structure shown in Patent Document 5 has a honeycomb shape extending as a flat surface in the horizontal direction, which is different from a honeycomb shape vertically formed in a vertical direction and extending in a plane shape like a tube furniture constituting the outer circumferential side of the building. Essentially different. Patent document 6 is also the same.

It is expected that if the tube furniture in which the hexagonal lattice is joined in a honeycomb shape is realized, a very strong structure can be obtained. To construct such a tube furniture requires a method of connecting the hexagonal grid to form a vertical plane or curved surface formed. The honeycomb structure is basically a set of unit structures of the same shape, so when constructing this structure, it is better to construct the structure unit by connecting the structure unit of a certain shape rather than joining one pillar and the girder one by one. Therefore, there is a demand for a structural unit having a predetermined shape capable of efficiently constructing a honeycomb-shaped structure.

The precast concrete member of Patent Document 1 can construct a building structure having a unit structure in which a plurality of sides extend radially from the center. However, since the center, which is a disadvantage of all sides, is the point where stress is most concentrated, joining all the columnar members to one joining member at this center position is not preferable in terms of structural stability.

In addition, since the three-pronged column of Patent Document 2 is a unit structure in which four sides extend radially and three-dimensionally from the center, the hexagonal structure in which these are joined necessarily becomes a three-dimensional hexagonal structure. Therefore, it is not possible to construct a flat or curved surface of the tube furniture in which the hexagonal lattice is joined in a honeycomb shape.

In addition, Patent Document 7 is not a method of constructing the whole by sequentially connecting one panel unit, but a method of fixing all the panels in a dome shape after connecting them in a planar manner. Moreover, in patent document 8, it is a structure which connects panel units with each other by arrange | positioning a tension material in a vertical direction or a horizontal direction, and has no relationship with a honeycomb shape. Patent document 9 is also a structure which ensures strength by making a dome shape mainly. Therefore, when it is based on patent documents 7-8, the tube furniture which has a honeycomb-shaped main frame by which structural units were joined cannot be realized.

In view of the above situation, an object of the present invention is to provide a building structure having a honeycomb-shaped main frame which is vertically formed and extends in a plane shape.

Effects of the Invention

(A) Effects of the invention mainly related to claims 1, 6, 13 or 15 are as follows. The building structure of the present invention has a main frame connecting a plurality of structural units, and in one embodiment, each structural unit is a hexagonal lattice that is a unit grid when viewed from the front of a virtual honeycomb shape vertically formed and extending in a planar shape. It is arrange | positioned in the position containing each vertex, respectively. Moreover, in another embodiment, one structural unit is arrange | positioned each in the position containing both of two adjacent vertices in the hexagonal grating | lattice which is a unit grating | lattice. In another embodiment, the first structural unit disposed at a position including one vertex and the second structural unit disposed at a position including two vertices are mixed. Here, the "virtual honeycomb shape" (hereinafter, simply abbreviated as "honeycomb shape") itself is not a member having an entity, but in order to define the positional relationship between each structural unit and the positional relationship between adjacent structural units. It is assumed to exist in real space.

In any arrangement described above, means for joining the structural units to each other by opposing the joint surfaces formed on a part of the respective outer peripheral surfaces of the two structural units adjacent to each other, and the joined surface is any one of the hexagonal lattice. Intersect with the side of. In addition, when the plurality of structural units are connected in this way, an opening surrounded by all the structural units disposed on the hexagonal lattice is formed at the center portion of each hexagonal lattice.

In this way, a plurality of connected structural units can be arranged so as to cover each vertex and each side of all hexagonal lattices forming the virtual honeycomb shape. That is, when paying attention to one hexagonal lattice, a plurality of (six, five, four or three) structural units are connected in a ring shape along six sides to form an opening in the center portion. As a result, a building structure having a honeycomb-shaped main frame that is vertically formed and extends in a plane shape is realized. In particular, the periphery of the tube furniture itself can be a honeycomb structure. Moreover, since the slab can be formed in arbitrary positions about the structural unit which comprises this honeycomb-shaped main frame, the height of each layer can be designed freely.

In the building structure having the honeycomb-shaped main frame according to the present invention, the structural unit is arranged to include the positions of the respective vertices of the hexagonal lattice in which the stress is most concentrated. In other words, the structural units are not joined to each other at the position of each vertex, which is very strong against stress. For example, the structure stability is excellent compared with the structure which joins a linear member in each vertex of a triangle or hexagon in which stress concentrates like patent document 1 and patent document 5 mentioned above. Furthermore, in the honeycomb-shaped building structure according to the present invention, the surfaces of the two structural units joined to each other intersect with one side of the hexagonal lattice. That is, the joining of the two structural units is made on each side of the hexagonal lattice, which is preferable because the stress is the smallest. As a result, a large-span furniture is possible in the main frame using the structural unit of the present invention.

Moreover, the structural unit of this invention can design relatively freely about the shape of the part irrespective of the said arrangement | positioning condition and joining condition. For example, the size of the opening formed in the center portion of the hexagonal lattice can be changed by changing the shape of the outer circumferential surface (that is, the non-bonded surface) other than the bonded surface in the structural unit. It can also respond to variations in design.

Moreover, since the structural structure using the structural unit of this invention connects and builds structural units of the same shape or a similar shape basically according to a repeating pattern, it is possible to unify the structural units into one type or a maximum of two or three types, for example. Can be. In this way, the mass productivity is also excellent. As a result, manufacturing cost can be reduced, workability can be improved, and air can be shortened. However, since the structural units of the present invention can be joined to each other and can produce similar shapes having a wide variety of types, there is naturally no upper limit to the number of types.

(B) The effect of the invention mainly concerning Claims 2-5, 7-11, 16-28 is as follows. The structural unit of the present invention is preferably made of precast concrete (hereinafter abbreviated as "PC") zero. (Hereinafter, a structural unit made of a PC may be referred to as a "PC panel.") A PC panel includes a pair of panel surfaces each having a front surface and a rear surface whose outer circumferential surfaces face each other, and a peripheral edge of each of the pair of panel surfaces. A plurality of said joining surfaces are formed as a part of side surface which has a side surface extended between them. The PC panel is arranged such that its panel surface is along the surface of the virtual honeycomb shape. As the shape of the panel surface, for example, triangular shape, hexagonal shape, octagonal shape or X shape may be used. Form can be designed freely by formwork.

PC panels have higher strength than conventional reinforced concrete, enabling the construction of vibration-resistant building structures. As a result, it is possible to realize a building having good habitability due to less shaking.

PC panels are generally manufactured in factories as building parts, so quality control is easy. Therefore, it is easy to obtain the reliability of the safety of the produced structural unit and the building structure constructed using the same. It is easy to save and manage the structure history information.

In addition, the PC panel has a high rigidity in that its panel surface is wide in shape (for example, hexagonal or octagonal) in terms of plane dimensions. In addition, in terms of plane dimensions, the wider the shape, the greater the amount of concrete and the heavier the weight. In addition, the opening formed by these structural units becomes smaller as an opposite effect of a wide point in terms of plane. On the other hand, in the plane dimension, in the narrow shape, that is, the shape closer to the wire rod (for example, than the three-pronged or X-shaped type), the rigidity is low and the amount of concrete is low, resulting in light weight. And the opening formed by these structural units becomes large as an opposite effect of a narrow point in the plane dimension. It is possible to construct a building structure capable of freely controlling the rigidity by combining a plurality of PC panels having different shapes (that is, different rigidities).

For example, it is preferable to use a PC panel with a wider area in the plane of the lower layer to make the opening smaller, and to use a PC panel of a narrow area in the plane of the upper layer to make the opening larger (claim 14). . The opening may be enlarged in stages. The building structure thus constructed is excellent in vibration resistance. This is because in high-rise or high-rise buildings, the upper part is lighter, the lower part is heavy, and the stronger the shape, the higher the seismic resistance. In addition, such a building structure can be reasonably used without wasting concrete by reducing the amount of concrete in the upper system.

In addition, when the structural unit is made of a PC panel, it can be set to a size suitable for the size of the transport vehicle for efficient transportation. Moreover, by zero PC, formwork can be efficiently converted.

Furthermore, the use of high-strength concrete can contribute to resource saving because it can prolong the lifespan of the building structure, which is preferable as the skeleton of the SI (skeleton infill) separation method.

(C) Effects of the invention mainly related to claim 11, l6 or 20 are as follows. In the case where the structural unit is a PC panel, post tension is added to the tension member and the tension member that cross the opposing joining surfaces of the means for joining two neighboring structural units to each other, and to penetrate both structural units. It is preferable that the fixing unit is provided with each fixing unit on the side surface of the structural unit. By adding post-tension and fixing, firm bond strength can be obtained.

In addition, even when one PC panel is joined to other panel units adjacent to each other by three or four tension members extending in three or four directions in different directions, it is possible to secure a firm bonding strength.

In addition, the introduction of the press stress by post tension does not cause warpage or crack cracking even in the long-term stress (even if it is blocked by the press stress), so that the entire cross section of the concrete works effectively against compression and tension. Furthermore, since it does not cause crack cracking, it is excellent also in preventing corrosion of the inserted tension material.

The honeycomb-shaped main frame constructed by using the structural unit of the PC panel into which the press stress according to the present invention is introduced is stronger than the furniture of the conventional press-rest concrete and ramen structure. For example, the ramen furniture of a conventional 15-story building is a very flexible sphere with an intrinsic period of about 1.5 seconds, whereas the furniture of a 15-story building according to the present invention is a very solid sphere with an intrinsic period of about 0.3 seconds. Thus, the present invention is suitable for the construction of the upper sphere of the base isolation structure. This is because if the upper sphere of the base isolation structure is flexible, there is a risk of reducing the base isolation effect of the isolator.

(D) The effects of the invention mainly related to claim 26 are as follows. When the structural unit is a PC panel, it is preferable to form a plurality of slab connection holes penetrating the structural unit in a direction perpendicular to the pair of panel surfaces. By forming a slab connection hole at an appropriate position to connect the slab, a tension member can be inserted through the concrete slab and the post tension can be added to fix the slab. As a result, firm bonding strength with the slab can be obtained.

(E) The effects of the invention mainly related to claim 27 are as follows. When the structural unit is made of a PC panel, it is preferable that the joining surface is formed by any one of two inclined surfaces of the mountain type or two inclined surfaces of the valley type. It is possible to fit the structural unit formed in the shape of a mountain with the joining surface and the structural unit formed in the valley shape with the joining surface. As a result, it is possible to reliably prevent the load rotational movement around the axis perpendicular to the joint surface, and secure the steel joint.

(F) Effects of the invention mainly related to claim 28 are as follows. When the structural unit is a PC panel, the structural unit used for the portion where the virtual honeycomb shape is curved has a bent portion, that is, a bent portion. By arranging the structural units so that the bent portion is along the vertical forming direction of the virtual honeycomb shape, angles can be formed between the respective surfaces on both sides of the bent portion. The bending angle of the bent portion can be made relatively small and the actual curved surface can be obtained as a whole by repeating this slight bend a plurality of times. This makes it possible to construct a tube furniture having a curved shape (round, elliptical or part thereof) in the horizontal cross section.

(G) Effects of the invention mainly related to claim 12 are as follows. In the present invention, as long as a structural unit having the same shape can be manufactured in addition to the PC panel, an architectural structure having a main frame of steel frame, reinforced concrete frame, steel frame reinforced concrete frame, or wooden honeycomb shape can be constructed.

(H) Effects of the invention mainly related to claim 24 or 25 are as follows. When the structural unit arrange | positioned at two adjacent vertices in a hexagonal grating | lattice is made into a PC panel, it may become considerable size and weight compared with a normal PC panel. In such a case, it is preferable to use a half unit obtained by dividing the PC panel into two. Thereby, the main frame according to the present invention can be constructed without disturbing production, transportation, and assembly.

(I) Effects of the invention mainly related to claim 29 are as follows. The construction method of a building structure having a main frame in which a plurality of structural units connected to the PC panel are connected is arranged so that two neighboring structural units face each joining surface so that the respective tension member insertion holes coincide with each other. The two structural units are connected by inserting the tension member through the tension member insertion hole communicated with the two structural units and adding the tension member to fix the tension member. In this method, since the connection of a plurality of PC panels is completed two by one, the workability is good. In this work, since only one tension member is inserted and added, the post tension is added, and both ends thereof are fixed, so that the work amount is small and the work is simple. On the other hand, for example, in the case of the conventional ramen structure, it is difficult to complete the connection work for every two members because both the long span girders and the columns must be connected.

In addition, since the construction method according to the present invention is a dry construction method, curing time such as a wet construction method such as on-site reinforcement reinforced concrete tank is not required, and the air can be shortened.

Implement the invention  Best form for

Hereinafter, a basic embodiment of the present invention will be described with reference to FIGS. 1 to 6. In addition, although FIG. 1 thru | or FIG. 6 demonstrated using the Example using the structural unit by the PC panel suitable for this invention, the structural unit of this invention is not limited to a PC panel. Hereinafter, the "structural unit" may be referred to simply as the "unit".

1 is a partial front configuration diagram showing an embodiment of a main frame of a building structure constructed using a plurality of structural units of the present invention. For example, it corresponds to a part of the tube furniture forming the outer circumference of the building. Both arrows XY represent the horizontal direction and both arrows Z represent the vertical direction (the same in the drawings below). 1 (A1) is a part of the main frame using the unit (1). 1 (A2) shows the units 2 and 3 which are variants of the unit 1. 1B is a part of the main frame using the unit 4. 1 (B2) shows the units 5 and 6 which are variants of the unit 4.

1 shows the shape when the main frame and the structural unit are seen from the front, and the structural units 1 to 6, which are PC panels, have a predetermined thickness (direction perpendicular to the ground) (hereinafter, the same in the similar drawings). Do).

In FIG. 1, a part of the virtual honeycomb shape vertically formed in the vertical direction and extending in a plane shape is indicated by a dashed dashed line. The hexagonal lattice H1 that is the unit lattice is arranged in a direction in which the upper side (between the vertices h1 and h2) and the lower side (between the vertices h4 and h5) are horizontal.

In the present invention, the "virtual honeycomb shape" is a virtual object having a honeycomb pattern in which the hexagonal lattice H1 (or the hexagonal lattice H2 in Fig. 2 is repeated without gaps in the up, down, left, and right directions. This means that the honeycomb shape is not made of a member having an entity, but the virtual honeycomb shape is an important concept for defining the positional relationship between structural units that are members having an entity and the positional relationship between adjacent structural units. The present invention will be described assuming that a "virtual honeycomb shape" exists in the real space.

The virtual honeycomb shape is basically formed vertically in the vertical direction and widened in the plane shape. In addition, according to the design request, the case where the surface of the virtual honeycomb shape is vertically formed by inclining only a predetermined angle from the vertical direction is also included in the present invention. The term "surface shape" includes planar shape and curved surface shape (the same applies hereinafter).

The hexagonal lattice H1 that is the unit lattice is not necessarily a regular hexagon, but is at least bilaterally symmetrical (the same applies to the hexagonal lattice H2 in FIG. 2). Each of the six sides in the unit grid is shared by two neighboring unit grids, and each of the six vertices h1 to h6 is shared by three neighboring unit grids.

Referring to Fig. 1 (A1), six units 1 are arranged at positions including respective vertices h1, h2, h3, h4, h5, h6 of the hexagonal lattice H1. Two units respectively disposed at adjacent vertices (for example, h1 and h2, h2 and h3) are joined to each other by opposing a joint surface formed on a part of each outer peripheral surface thereof. Each of these joined six surfaces s1, s2, s3, s4, s5, and s6 intersects with any one side of the hexagonal lattice H1. For example, face s1 intersects the side between vertices h1 and h2. In other words, the joining between the units is not on the top of the hexagonal lattice H1 but on the side. As a result, all the units 1 arranged on the hexagonal grid H1 are connected in an annular shape and one opening portion W surrounded by these units is formed in the center portion of the hexagonal grid H1. The opening part W can also be said to be surrounded by the non-joint surface of each unit.

Thus, a plurality of structural units are arranged so as to occupy all the vertices and sides of the plurality of hexagonal lattices forming the honeycomb shape, and two neighboring structural units are joined by opposing each other's joint surfaces. As the joining means, for example, in the structural unit of the PC panel, a means for inserting through the tension member so as to intersect with the opposing joining surfaces of the two units and loading and fixing the post tension is preferable, but not limited thereto. In addition, the joints between the units are preferably steel joints, but may be intermediate between the steel joints and the oil joints, as necessary. The honeycomb structure has an effect of converting a part of bending stress into axial force and transferring it, but is effective because it absorbs bending stress that is not converted into axial force when the units are firmly joined together.

The unit 1 shown in FIG. 1 (A1) has a three-pronged panel surface as viewed from the front, and the joining surface with the unit where the side surfaces at the ends of the three leg portions extending from the center to three directions are adjacent to each other. Becomes The valley-shaped side between the joining surface and the joining surface is a non-bonded surface.

1 (A2) shows a modification thereof. The unit 2 is hexagonal when viewed from the front, and the six sides are alternately arranged with the long side and the short side. Sides (a, b, C) including the short side become the joining surface with neighboring units, and sides (d, e, f) including the long side are the non-joining surfaces. The unit 3 is the shape which deform | transformed the center of the long side of the unit 2 to mountain shape. As shown in Fig. 1 (A1) by dashed lines to show the units 2 and 3, the shapes of the units 1 to 3 are the positions and shapes of the joint surfaces (the positions and shapes relative to the hexagonal lattice, which are the same below). It is common and only the non-joint surface is deformed. Units with which a joint surface is common can be bonded even if the shape of a non-bonding surface differs (it is the same also in another unit example below). The shape of the non-bonded surface can be continuously deformed, for example, between the valley shape of the unit 1 to the mountain shape of the unit 3. For example, the non-bonded surface may be any one of a plurality of flat or curved surfaces, a valley surface, and a mountain surface. Several unit shapes are demonstrated in detail in each Example mentioned later.

As apparent from FIG. 1A1, the opening W formed by the unit 1 is the largest and the opening W formed by the unit 3 is the smallest. Thus, the opening part W formed becomes small, so that the panel surface of a unit becomes wider in surface dimension. Moreover, when the shape of a non-joined surface differs, the shape of the opening part W enclosed by them will also differ.

In FIG. 1 (B1), six units 4 are arrange | positioned in the position containing each vertex h1, h2, h3, h4, h5, h6 of the hexagonal grating H1, respectively. As the units 5 and 6 are indicated by broken lines, the units 4 to 6 have a common position and shape on the joint surface, and only the shape of the non-bonded surface is different. The units 4 to 6 are arranged on the same hexagonal grid H1 as in Fig. 1 (A1), but have a larger joint surface area than the units 1 to 3. Therefore, the area of the surface s1 to s6 which joined the neighboring units mutually becomes larger than the case of FIG. 1 (A1), and the size of the opening part W formed becomes small. The unit 4 is a concave curved surface in a non-joined surface. The unit 5 has a regular hexagonal panel face and is similar in shape to the unit 2. The unit 6 has a non-joined surface with a convex curved surface.

Here, the main frame is the main part of the structural sphere (also called skeleton), which is the main part of the structural strength. As shown in Fig. 1, in the main frame in which a plurality of structural units are arranged on the vertices and sides of the hexagonal hexagonal grid, the members of the structural unit located on each side of the hexagonal grid are connected to the inclined column or the girder as the structural element. It is considerable. For example, the tube furniture constructed according to the honeycomb shape made of the hexagonal lattice H1 of FIG. 1 consists of pillars arranged substantially alternately with zigzag columns, horizontal girders, and inclined girders alternately arranged. In this respect, it is a completely different structure from the general ramen structured tube furniture consisting of continuous horizontal girders and vertical columns.

2 is a partial front configuration diagram showing another embodiment of a main frame of a building structure constructed using a plurality of structural units of the present invention. Fig. 2A is a part of the main frame using the unit 2 shown in Fig. 1. The same is also used for these units, as shown by the broken lines in units (1) and (3). FIG. 2B is a part of the main frame using the unit 5 shown in FIG. 1. The same is also used for these units, as shown by the dashed lines for the units 4 and 6.

Hexagonal lattice H2 which is a virtual honeycomb-shaped unit lattice shown by a dashed-dotted line in FIG. 2 is disposed in a direction in which the left side (between vertices h5 and h6) and the right side (between vertices h2 and h3) become vertical directions. The hexagonal lattice H2 and the hexagonal lattice H1 are rotated by 60 ° in the case of a regular hexagon. The tube furniture constructed according to the honeycomb shape made of the hexagonal lattice H2 is substantially composed of pillars in which vertical pillars and inclined pillars are alternately arranged, and girder continuous in a zigzag.

In the units 1-6 shown in FIG. 1 and FIG. 2, one unit is arrange | positioned at each vertex of the hexagonal grid H1 or H2. Thus, one unit is shared by three neighboring hexagonal grids H1 or H2.

3 is a partial front configuration diagram showing another embodiment of a main frame of a building structure constructed using a plurality of structural units of the present invention. For example, it corresponds to a part of the tube furniture forming the outer circumference of the building. 3 (A1) is a part of the main frame using the unit 7. 3 (A2) shows the units 8 and 9 which are variants of the unit 7. 3B1 is a part of the main frame using the unit 10. 3 (B2) shows the units 11 and 12 which are variants of the unit 10.

In FIG. 3, a part of the virtual honeycomb shape which is vertically formed in the vertical direction and extends in a plane shape is indicated by a dashed dashed line. The hexagonal lattice H1 that is the unit lattice is arranged in a direction in which the upper side (between the vertices h1 and h2) and the lower side (between the vertices h4 and h5) become horizontal directions.

Referring to FIG. 3A1, three units 7 are a first pair h1 and h2, a second pair h3 and h4, and a third in which the hexagonal lattice H1 is a pair of two vertices neighboring each other. It is arrange | positioned at the position containing each pair of pair h5 and h6. Two units arranged in a pair of neighboring vertices (for example, the first pair h1 and h2 and the second pair h2 and h3 respectively) face the joining surface formed on a part of each outer peripheral surface thereof. Each of these joined three faces s2, s4, s6 intersects with one side of the hexagonal lattice H1, for example, the face s2 is between the vertices h2 and h3. In other words, the joining of the units is performed on the sides instead of the vertices of the hexagonal grid H1. As a result, all the units 7 disposed on the hexagonal grid H1 are connected in a ring shape. One opening portion W surrounded by these units is formed in the center portion of the hexagonal lattice H1, and the opening portion W may also be surrounded by the non-bonding surface of each unit.

"Neighboring vertices" refer to those located at both ends of one side of a hexagonal lattice forming a honeycomb shape. Each of the plurality of units arranged in an annular shape on one hexagonal lattice does not necessarily have to be disposed at two vertices in the hexagonal lattice, and one vertex of the hexagonal lattice and one vertex of the adjacent hexagonal lattice are paired. May exist (refer FIG. 5 and FIG. 6 mentioned later).

The unit 7 shown in FIG. 3 (A1) has a shape in which the two ends of one rod-shaped portion have four legs each branched in two directions when viewed from the front, and at the tip of four legs extending in four directions. The side surface of the surface becomes a joining surface with neighboring units. The concave side between the joining surface and the joining surface is a non-bonded surface. The shape of the unit 7 can be said to be the shape which joined together and integrated the joining surface of each leg part using two units 1 shown in FIG. That is, arranging two units shown in FIG. 1 and arranging one unit shown in FIG. 3 may result in the same shape as a result.

3 (A2) shows a modification. The unit 8 is octagonal when viewed from the front, and the eight sides are alternately arranged with the long side and the short side. The side surfaces (a, b, c, d) including the short sides become the joining surfaces with the units adjacent to each other, and the side surfaces (e, f, g, h) including the long sides are the non-bonding surfaces. The unit 9 is the shape which deform | transformed the center of the long side of the unit 8 to mountain shape. As shown to the unit 8 and 9 by the broken line in FIG. 3 (A1), the shape of the unit 7-9 has the relationship which the position and shape of a joint surface are common, and deformed only the non-bonding surface. The shape of the non-joint surface can be continuously deformed, for example, between the valley of the unit 7 and the mountain of the unit 9. Various unit shapes are explained in full detail in the below-mentioned Example.

As is apparent from FIG. 3A1, the opening W formed by the unit 7 is the largest, and the opening W formed by the unit 9 is the smallest. As described above, the wider the panel surface of the unit is, the smaller the opening W formed. Moreover, when the shape of a non-joined surface differs, the shape of the opening part W enclosed by them will also differ.

In FIG. 3 (B1), three units 10 have a first pair h1 and h2, a second pair h3 and h4, and a third pair, in which the hexagonal lattice H1 is a pair of two vertices neighboring each other. It is arrange | positioned at the position containing each pair of h5) and (h6). As the units 11 and 12 are indicated by broken lines, the units 10 to 12 have a common position and shape on the joint surface, and only the shape of the non-bonded surface is different. The units 10 to 12 are arranged on the same hexagonal grid H1 as in Fig. 3A1, but the area of the joining surface is wider than that of the units 7 to 9. Therefore, the area | region of the surface s2, s4, s6 which joined the neighboring units mutually becomes larger than the case of FIG. 3 (A1), and the size of the opening part W formed becomes small. The unit 10 has a non-joined surface with a concave curved surface. The unit 11 is a variant having an octagonal panel surface and similar to the unit 8 but having a different ratio of the length of the short side and the long side. The unit 12 has a non-joined surface with a convex curved surface.

4 is a partial front configuration diagram showing another embodiment of the main frame of the building structure constructed using a plurality of structural units of the present invention. Fig. 4A is a part of the main frame using the unit 8 shown in Fig. 3. The same is used also for these units as shown to the unit 7 and 9 with a broken line. 4B is a part of the main frame using the unit 11 shown in FIG. The same is also used for these units, as shown by the broken lines for the units 10 and 12.

In the hexagonal lattice H2, which is a virtual honeycomb-shaped unit lattice shown by a dashed dashed line in FIG. 4, the left side (between the vertices h5 and h6) and the right side (between the vertices h2 and h3) are arranged in the vertical direction. Therefore, the tube furniture constructed according to the honeycomb shape made of the hexagonal lattice H2 is substantially composed of pillars arranged in alternating vertical pillars and inclined pillars and girders continuous in a zigzag.

The arrangement of the units shown in Figs. 3 and 4 is one example, and the pattern for arranging the hexagonal lattice H1 or H2 to include two pairs of adjacent vertices is not limited thereto. Although not shown, for example, three units may be arranged with the first pair as h2 and h3, the second pair as h4 and h5, and the third pair as h6 and h1 in FIGS. 3 and 4, respectively.

In the arrangement example of each unit shown in Figs. 3 and 4, all three units are arranged on three pairs of vertices included in one hexagonal grid, but one unit is a hexagon different from one vertex of the hexagonal grid. They may be arranged in pairs of one vertex of the grid, provided that the vertices are at both ends of one side. Other modifications of the arrangement pattern will be described later with reference to FIGS. 5 and 6.

In the units 7-12 shown in FIG. 3 and FIG. 4, one unit is arrange | positioned so that it may contain two vertices of hexagonal lattice H1 or H2. Thus, one unit is shared by four hexagonal grids H1 or H2.

FIG. 5: is a front block diagram which shows an example of the arrangement pattern of the structural unit based on the honeycomb shape formed from the hexagonal grating | lattice H1. As an example, the unit 8 shown in FIG. 3 is arrange | positioned according to the arrangement pattern A of an upper side, and the arrangement pattern B of a lower side, respectively. Any of the units 7 to 9 shown in Fig. 3 may be used and the units may be arranged in the same manner.

The arrangement pattern A is configured by repeating the arrangement of the three units shown in FIG. 3. In the arrangement pattern A, three types of openings Wa, Wb, and Wc are formed. The openings Wa and Wb are triangles opposite each other and the openings Wc are hexagonal. The opening Wa is surrounded by three units, and these three units occupy two vertices included in this hexagonal lattice (the same applies to the opening portion Wb). On the other hand, the opening Wc is surrounded by six units, each of which does not occupy two vertices of the hexagonal grid, but occupies one vertex of the hexagonal grid and one vertex of the adjacent hexagonal grid. .

Arrangement pattern B is arrange | positioned so that one unit may occupy two vertices of the upper edge and the lower edge (horizontal direction) in all hexagonal gratings H1. Therefore, four units are arranged in one hexagonal grid. Two of the four units occupy four vertices of the upper and lower sides, and the other two occupy one vertex of this hexagonal grid and one vertex of the adjacent hexagonal grid. In the arrangement pattern B, a rectangular opening Wd is formed.

In addition, arrangement | positioning pattern (A) and (B) can be connected continuously. The pentagonal opening We is formed in the boundary part.

FIG. 6: is a front block diagram which shows an example of the arrangement pattern of the structural unit based on the honeycomb shape formed from the hexagonal grating | lattice H2. As an example, the unit 8 shown in FIG. 3 is arrange | positioned according to the arrangement pattern A of the left side, and the arrangement pattern B of the right side, respectively. Even if any of the units 7 to 9 shown in Fig. 3 are used and these units are mixed, they can be arranged in the same manner.

The arrangement pattern A is configured by repeating the arrangement of the three units shown in FIG. 4. In the arrangement pattern A, three types of openings Wa, Wb, and Wc are formed. The openings Wa and Wb are triangles opposite each other and the openings Wc are hexagonal. The opening Wa is surrounded by three units, and these three units occupy two vertices included in this hexagonal lattice (the same applies to the opening portion Wb). On the other hand, the opening Wc is surrounded by six units, each of which does not occupy two vertices of the hexagonal grid, but occupies one vertex of the hexagonal grid and one vertex of the adjacent hexagonal grid. .

Arrangement pattern B is arrange | positioned so that one unit may occupy two vertices of both ends of a left side and a right side (vertical direction) in all hexagonal gratings H2. Therefore, four units are arranged in one hexagonal grid. Two of the four units occupy four vertices on the left and right sides, and the other two occupy one vertex of this hexagonal grid and one vertex of the adjacent hexagonal grid. In the arrangement pattern B, a rectangular opening Wd is formed.

In addition, arrangement | positioning pattern (A) and (B) can be connected continuously. The pentagonal opening We is formed in the boundary part.

In FIG. 6, another mixed pattern is shown in an upper portion as an example. On the left side of the mixed pattern, the unit 7 is connected to the uppermost unit of the unit 8 of the arrangement pattern A. The units 8 and 7 can be connected because the connection surfaces are common. On the right side of the mixed pattern, the unit 1 shown in FIG. 1 is connected to the uppermost unit of the unit 8 of the arrangement pattern B, and the unit 7 is further connected to the unit 1. Thus, since the connection surface is common, the unit 1-3 shown in FIG. 1 and the unit 7-9 shown in FIG. 3 can be mixed and connected.

Although not shown, the units 4 to 6 shown in FIG. 1 and the units 10 to 12 shown in FIG. 3 are also connected in common because the connection surfaces are common.

In addition to the variety of the shape of the structural unit shown in FIGS. 1 to 4 described above, as shown in FIGS. 5 and 6, there are also various variations in the arrangement pattern. Will be available.

The specific Example shown below is an example of these modified forms, and this invention is not limited to these forms.

Example  One

With reference to FIGS. 7-14, the Example of the building structure which has the main frame which arrange | positioned and connected the structural unit in a virtual honeycomb shape is demonstrated.

FIG. 7: (A-C) is a figure which shows an example of the main frame of the building structure constructed using the three-pronged structural unit 1 shown in FIG. (A) is an external perspective view of the whole tube furniture 100 which is a main frame. (B) is the front view which expanded and showed a part of tube furniture 100 of FIG. 7 (A). (C) is a top view.

The tube furniture 100 shown in FIG. 7 (A) is constructed based on a virtual honeycomb shape having the hexagonal grid H1 shown in FIG. 1 as a unit grid, and the virtual honeycomb shape as a whole has a tubular shape, that is, a tube shape. The axis of the tube extends along the vertical direction. When the three-pronged unit 1 is used as the structural unit disposed on the virtual honeycomb shape, the appearance shape of the completed main frame is almost identical to the virtual honeycomb shape as a base. This is because one inclined column or girder is formed by joining legs of two neighboring units 1 adjacent to each other, and the inclined column or girder occupies one side of the hexagonal grid of virtual honeycomb shape.

Note that the hexagonal lattice H1 is a regular hexagon, and it is not necessarily a regular hexagon as long as it is symmetrical.

As shown to Fig.7 (B), the hexagonal structure is formed by the six units 1 arrange | positioned at one hexagonal grid H1 (this is called "hexagonal structure part"). However, only one leg part among three leg parts of each unit 1 is contained in one hexagonal structure part. The hexagonal structure portion is composed of six linear structural members of an upper side member (r1), an upper right side member (r2), a lower right side member (r3), a lower side member (r4), a lower left side member (r5), and an upper left side member (r6). It is composed. The tube furniture constructed in this way is completely different from the conventional ramen-shaped tube furniture in that the girders are not continuously connected in the horizontal direction and the pillars are all composed of inclined columns that are continuously zigzag.

As shown in Fig. 7B, the hexagonal structure portion formed by the six units 1 is symmetrical, for example, a right-side member which is two inclined pillars inclined in opposite directions with respect to the vertical direction, respectively, for the right side ( r2) and the lower right side member r3 are connected and arranged. The right upper side member r2 is inclined by the angle α with respect to the vertical direction, and the right lower side member r3 is inclined by the angle −α with respect to the vertical direction. The upper left side member r6 constituting the left side is an inclined column inclined similarly to the lower left side member r5. The upper side member r1 and the lower side member r4 are horizontal girders. The joint between the pillars and the pillars and girders is a strong joint.

Such a building structure can exert great bearing capacity against horizontal loads that will come from any direction in that it is a tube structure. Moreover, in the tube furniture which consists of a hexagonal structure part, the coupling | bonding of all the pillars and girders is stabilized in balance. As a result, the bending stress generated at the nodal point of the column and the girder due to the load force becomes smaller than the stress in the tube furniture having the general ramen structure. This is because part of the bending stress is transferred to the axial force of the member (inclined column or girder). In addition, since the PC member is strong against the compressive force, it is advantageous in supporting the axial force.

In addition, as shown in Fig. 7B, in the tube furniture 100, there is no joint surface between the units 1 at the nodal point of the column and the girder, and the joint surface between the units 1 is at the midpoint of the column and the girder. have. Also in this respect the tube furniture according to the invention is advantageous in structural strength.

As shown in the top view of Fig. 7C, the cross-sectional shape of the tube furniture 100 is almost square in the illustrated example. The faces of the hexagonal structures formed at the four corners of the cross-sectional shape are oriented in the direction of the apex of the rectangle, and the four corners of the rectangle are notched. In addition, although the side surface of the tube furniture 100 of FIG. 7 is comprised substantially flat, the cross-sectional shape may be a circular shape (tube furniture consists of curved surfaces), arbitrary polygons, and a shape containing a recessed part may be sufficient. When the virtual honeycomb shape has a curved surface or a bent portion, a structural unit having a special shape may be used for the portions, which will be described later.

FIG. 8 is a partially enlarged view of the main frame 100 of FIG. 7 (in FIG. 8, the hexagonal lattice H1 is represented by a regular hexagon). As shown in the figure, six units 1 (1) to 1 (6) are used on one hexagonal grid H1 (the parentheses denoted by the symbols are numbers assigned to each unit arranged in one hexagonal grid). Is the same below). One unit 1 is a PC member extending in three directions from the center and having three legs. When viewed from the front, the panel surface has a three-pronged shape. The branch part in each unit 1 is located in each vertex h1-h6 of the hexagonal grid H1. The junction parts s1 to s6 between the units 1 adjacent to each other are located at the midpoint of each side of the hexagonal lattice H1 and are not at the vertex of the hexagonal lattice H1. Each leg part of the unit 1 occupies 1/2 of the length of each side of the hexagonal grating H1. Two of the three legs belong to one hexagonal grid and the other belongs to the other hexagonal grid. In any unit 1, two of the three legs are used as inclined columns and one is used as a girder.

In the center portion of the hexagonal lattice H1, an opening W surrounded by six units 1 (1) to 1 (6) arranged on the hexagonal lattice H1 is formed. In this example, the shape of the opening portion W is a hexagon in the same direction as the hexagonal lattice H1.

As shown in FIG. 8, in the midpoint of each side of the hexagonal grating | lattice H1, the joining surfaces of two adjacent units 1 oppose each other, and the units are joined. Joining of adjacent units with each other is made of tension members 21a, 21b, 21c shown by broken lines. For example, in the units 1 (1) and 1 (2), the tension member 21a penetrates the joint surfaces facing each other. After the post tension is added to this tension member 21a, both ends are fixed by a pair of fixing devices 22a and 22a. Similarly, in the units 1 (2) and 1 (3), the tension member 21b penetrates and is fixed by the fixing holes 22b and 22b. Similarly, in the units 1 (3) and 1 (4), the tension member 21c penetrates and is fixed by the fixing holes 22c and 22c. Thus, by joining adjacent pairs of units included in the whole unit, each joining surface is prevented from rotation and becomes a strong joint. In addition, the strength of the steel joint is enhanced by the post tension by the tension member.

9 is an enlarged perspective view showing the bonding state of two structural units in more detail. In FIG. 9, the leg part of the lower part of the unit 1 (3) and the leg part of the upper part of the unit 1 (4) are joined, and the inclined pillar of the lower-right member of a hexagonal structure part is formed. The joint surface is at the midpoint position of the inclined column. Moreover, when the joining surfaces of the leg ends of both units face each other, the tension member insertion holes (described in detail in Fig. 10) formed inside each unit are aligned so as to communicate with each other. Thereafter, the tension member 21c is inserted into the tension member insertion hole in communication. The tension member 21c is usually a PC steel. The tension member 21c is inserted through the valley between the other two legs of the unit 1 (3) from the valley between the other two legs of the unit 1 (4). Subsequently, both ends are fixed and fixed by the fixing means 22c and 22c in the state which added the post tension to the tension material 21c.

Joining of two neighboring units with each other is as described above. Thus, in the central part inside the unit 1, three tension members extending in different directions intersect in appearance. Since the central part of the unit 1 is located at each vertex of the hexagonal lattice, the part where the stress is most concentrated structurally, but since there is no joint at this part and the tension member is arranged in the inside, a very strong structure is realized. do. Moreover, joining of two units is made in the center part of each edge | side with comparatively small stress, and is structurally advantageous.

By introducing the press stress by post tension, the entire cross section of concrete acts effectively on compression and tension without causing warpage or crack cracking even for long-term stress. The result is a large span of furniture. Moreover, since it does not cause a crack crack, it is excellent also from the corrosion prevention viewpoint of the inserted tension material (it is the same also in each following example).

Moreover, when joining the joining surfaces of two units, it is preferable to form a some gap between two opposing joining surfaces, and to fill the gap with larger mortar, resin mortar, grout, etc. of strength than PC. These fillers can easily absorb construction errors and greatly improve workability (the same applies to each of the following examples).

10 is a diagram showing in detail the configuration of the unit 1. FIG. 10 (A) is a side view as seen from the joining surface 1a side of one leg tip, and FIG. 10 (B) is an X-X cross-sectional view of (A).

The unit 1 is a PC panel manufactured using a given formwork. As apparent from Fig. 10B, the unit 1 has a three-pronged panel surface as viewed from the front, and as shown in Fig. 10A, the front panel surface 1i and the rear panel surface ( There is a predetermined thickness between 1j). The unit 1 is provided with three legs which branch and extend in 3 directions from the center C, and the side surface 1a, 1b, 1c in the front-end | tip of each leg part is a joining surface. Each joining surface 1a, 1b, 1c is perpendicular to the direction in which each leg extends. The width of each leg when viewed from the front is constant and the cross section of each leg becomes a rectangle. The thickness and width of each leg is set to suit the building structure to be constructed.

The side surface other than the tip of each leg part is a non-joint surface. Between the joining surfaces 1a and 1b, the non-bonding surfaces 1d2 and 1d3 form a valley shape. Between the joining surfaces 1b and 1c, the non-bonding surfaces 1e2 and 1e3 form a valley shape. Between the joining surfaces 1c and 1a, the non-bonding surfaces 1f2 and 1f3 form a valley shape.

As shown in FIG. 10 (B), three tension member insertion holes 1a3, 1b3, and 1c3 are formed in the interior of the unit 1. In addition, these tension member insertion holes are formed at the time of manufacturing the PC, and a sheath (not shown) for passing the tension member is buried. These three tension member insertion holes 1a3, 1b3, and 1c3 appear to intersect when viewed from the front, but as shown in Fig. 10A, they are formed at different positions in the thickness direction so as not to overlap each other. The tension member insertion hole 1a3 penetrates from the joint surface 1a to the valley bottom part 1e1 between a 2nd leg part and a 3rd leg part along the axial direction of a 1st leg part. Similarly, the tension member insertion hole 1b3 penetrates from the joining surface 1b to the valley bottom part 1f1 between a 3rd leg part and a 1st leg part along the axial direction of a 2nd leg part. Similarly, the tension member insertion hole 1c3 penetrates from the joint surface 1c to the valley bottom part 1d1 between a 1st leg part and a 2nd leg part.

In the unit 1 shown in FIG. 10, the three legs are formed with the same length and at equal isosecond intervals (that is, by 120 degrees). Such a unit 1 is used when the hexagonal lattice H1 is a regular hexagon, as shown in FIG. In this case, any leg may be used as either an inclined column or a girder. That is, the unit 1 can be used in any direction, and the workability is good.

However, as described in FIG. 7, the hexagonal lattice H1 has a symmetrical shape, but does not necessarily have to be a regular hexagon, and the length of the side serving as an inclined pillar and the length of the side serving as a girder may be different. In this case, the unit 1 is different in length from one leg portion used as the girder and two leg portions used as the inclined pillar. Also in this case, the two legs serving as the inclined pillars have the same length. In addition, the angles formed by each of the one leg to be the girder and the other two legs to be the inclined column must be equal to each other, but the angle may be different from the angle formed by the two legs that are the inclined column.

11 is a perspective view showing a part of the main frame constructed by the modification of the unit 1. This variant consists of a combination of two kinds of units 1A and 1B and is alternately arranged on the hexagonal grid. The point different from the above-mentioned unit 1 is the shape of the joining surface in each leg part.

The joining surfaces of the three leg portions of the unit 1A form a mountain shape consisting of two inclined surfaces la4 and 1a5, 1b4 and 1b5, 1c4 and 1c5, respectively. On the other hand, the joining surfaces of the three leg portions of the unit 1B form a valley shape consisting of two inclined surfaces la6 and 1a7, 1b6 and 1b7, 1c6 and 1c7, respectively.

The mountain shape of the joining surface of the unit 1A and the valley type of the joining surface of the unit 1B are shaped to fit each other. Therefore, the units 1A and 1B are always arranged alternately and joined together by fitting the joining surfaces. In addition, the fixing method in the added state of the post tension by the tension member is the same as in the above-described embodiment. When the joining surfaces are fitted together and joined in this way, the rotation of the leg portion around the shaft can be reliably prevented by the engagement between the mountain and valley shapes, and a more robust structure can be obtained.

In addition, the shape of the joining surface of two types of units fitted to each other is not limited to the mountain shape and valley shape shown in FIG. Combinations of other shapes are possible as long as the effect of preventing rotation around the axis can be obtained. For example, a square convex part is formed in the center part of one joining surface, a square concave part is formed in the center part of the other joining surface, and these square convex parts and a square concave part are fitted together. The example of the fitting shape of the mountain shape and the valley shape shown in FIG. 11 is simple, and in addition to being easy to work, the contact surface is inclined so that the contact area is widened, resulting in an improvement in joining strength.

12 is a perspective view illustrating a joining method of the unit 1 and the slab. A plurality of slab connection holes 1g penetrating the front and back panel surfaces of one of the three leg portions of the unit 1 are formed. And the unit 1 is arrange | positioned so that the leg part which formed the slab connection hole 1g may become a girder. On the other hand, a plurality of tension members 31 are formed in the PC slab 30 in advance. Each slab connection hole 1g is formed at a position corresponding to each of the plurality of tension members 31 and is set to a diameter in which the tension members 31 can be inserted.

When the unit 1 and the PC slab 30 are joined together, the tension members 31 are inserted into the respective slab connection holes 1g, and the tension members 31 are fixed by the fixing tool in the state in which the post tension is added to the tension members 31.

FIG. 13A is a diagram partially showing an example of the main frame 101 constructed by using another modification of the unit 1. The main frame 101 has a virtual honeycomb shape as a base and is a curved surface instead of a plane. The overall shape of this main frame 101 is a cylindrical tube furniture. FIG. 13B shows a top view of the unit 1C for building the main frame 101 of (A) and FIG. 13C shows a unit 1C for building the main frame 101 of (A). ) Is a front view.

As shown in Fig. 13 (B) and (C), the unit 1C has a panel surface 1Ci1 of a leg portion (in this example, having a joining surface 1Ca at its tip) that forms a girder to form an inclined column. The angle β is formed with respect to the panel surface 1Ci2 of the other two leg portions (in this example, each has the joining surfaces 1Cb and 1Cc at the distal ends). In other words, the former one leg is bent at the bending portion 1Ck with respect to the latter two leg portions. By joining the units 1C having such curved portions 1Ck with each other, a curved main frame can be constructed. As another example, the curved unit 1C may be used for a bent portion (for example, a corner of the tube furniture shown in FIG. 7) in which two planes in the main frame intersect. Moreover, the magnitude | size of angle (beta) shall be the grade which does not interfere with the joining of two units 1C with the tension material which added the post tension, or the joining of the unit 1C and the other joinable unit.

In addition, when the curved unit 1C is used, not only a curved surface that bends in one direction but also a curved surface that bends in the opposite direction can be formed continuously. For example, it is a curved surface that becomes wavy when viewed from the upper surface.

When the main frame is parallel to the vertical direction also in the curved part as in the tube furniture shown in Fig. 13A, the unit 1C is disposed so that the bent portion 1Ck is parallel to the vertical direction. In other embodiments, the main frame may not be parallel to the vertical direction in the curved portion (for example, a curved shape such as a part of the dome), but in this case, the direction of the bend 1Ck and the direction of the curved surface of the main frame may be different. Place them in response.

By using the flat unit 1 shown in FIG. 10 and the curved unit 1C shown in FIG. 13 in combination, a main frame having a flat portion and a curved portion can be freely constructed.

Fig. 14 shows a unit 1D which is a variation of the unit 1 shown in Fig. 10, (A) is an external perspective view and (B) is a part of the main frame in which six units 1D are arranged and connected on a hexagonal grid. It is a front view which shows.

The unit 1D may be joined to the above-described unit 1 or unit 1C in common with the unit 1 in shape and position of the joining surfaces 1Da, 1Db, and 1Dc. The unit 1D is different from the unit 1 in the shape of the non-bonded surface. The unit 1D can be said to be a shape which made shallow the depth of the valley of the non-joined surface of the unit 1. In the unit 1D, the width of each leg portion is not constant, and the width increases from the joining surfaces 1Da, 1Db, and 1Dc toward the center. For example, the angle δ (the angle formed by the side surface 1Df2 with respect to the bonding surface 1Dc) of the side surfaces 1Df3 with respect to the adjacent bonding surface 1Da becomes the obtuse angle (in the unit 1). δ is 90 degrees). In addition, as a deformation | transformation form of the unit 1, what is contained in the range of 90 degrees <= (delta) <120 degrees in panel shape shall be included in a "three branched shape".

Moreover, when delta = 120 degrees, a valley will disappear and it will become a hexagon like unit 2 shown in FIG.

As shown to FIG. 14 (A), the tension material insertion hole 1Db3 is opened in valley bottom part 1Df1 of valley side surfaces 1Df2 and 1Df3.

As shown in Fig. 14B, when six units 1D are connected in a ring shape, the opening portion W in the center portion thereof is smaller than the opening portion surrounded by the unit 1 shown in Fig. 8.

In addition, although the width | variety of all the leg parts is changed with respect to the unit 1 of FIG. 10 in the unit 1D of FIG. 14, only the width | variety of one or two leg parts may be changed. The main frame may be constructed by mixing the unit 1, the unit 1D, and another modified form having a joining surface that can be joined to each other. This makes it possible to meet a wide range of sizes and design requests.

Example  2

With reference to FIGS. 15-21, the other Example of the building structure which has a main frame which arrange | positioned and connected the structural unit in a virtual honeycomb shape is demonstrated.

15 is a front view showing a part of the main frame 102 of the building structure constructed using the structural unit. For example, it is a part of tube furniture similar to FIG. 7 (A) mentioned above. 16 is a partially enlarged perspective view of the main frame 102 of FIG. 15.

The main frame shown in FIG. 15 is constructed by arranging and connecting the structural units 2 shown in FIG. 1 to a virtual honeycomb shape having the hexagonal grid H1 (indicated by a thick one-dot dashed line) shown in FIG. 1 as a unit grid.

One unit 2 has a hexagonal panel surface having six sides as seen from the front as shown in FIG. 15 and has a predetermined thickness (direction perpendicular to the ground). Therefore, as shown in FIG. 16, it has six side surfaces extended between each side of each of a pair of panel surfaces of a front side and a back side. In the example shown in figure, the six sides which comprise the circumferential edge of a hexagonal panel surface are comprised by alternately arrange | positioning 2 types of different sides of a length. The long side is referred to as the "long side" and the short side is referred to as the "short side". Correspondingly, the side surfaces extending between the short sides of both panel surfaces become the "short side surfaces" and the side surfaces extending between the long sides become "long sides". In each unit, three short sides and three long sides are alternately arranged. Moreover, it is preferable to make three short side surfaces in each unit a joining surface, and three long side surfaces to a non-bonding surface. In the case where the short side is the joining surface, a wider opening portion W can be obtained than when the long side is the joining surface. However, depending on the application, the long side may be a joining surface. As a special example, if the length of the short side and the long side are the same, it becomes a regular hexagon (structural unit 5 shown in FIG. 1).

As shown in Fig. 15, six units 2 (1), 2 ( 2), 2 (3), 2 (4), 2 (5) and 2 (6) are arranged. The joining surfaces, which are short sides of each of the neighboring units, are opposed to each other. The joined surfaces s1, s2, s3, s4, s5 and s6 intersect with either side of the hexagonal lattice H1. On the hexagonal grid H1 each unit uses two joining surfaces to join with both neighboring units. Thereby, six units are connected in an annular shape, and an opening portion W (indicated by a bold dashed line) surrounded by these units is formed at the center portion thereof. At this time, the other joining surface in each unit can be connected to the short side of one unit which is radially directed from the center and included in the adjacent hexagonal lattice.

As is apparent from FIG. 15, one unit 2 is disposed at one vertex shared by three hexagonal grids H1 adjacent to each other and shared by three hexagonal grids H1.

The hexagon of the panel surface of the unit 2 may have a deformation | transformation which differs in the ratio of a long side and a short side. When the cross diameters (distances between the long sides and the short sides opposite to each other) are the same, the larger the difference between the long side and the short side is, the larger the opening W of the center portion of the hexagonal grid H1 is and the length of each side is the same. W) is the smallest regular cube. On the other hand, the larger the difference between the long side and the short side is, the smaller the area of the joint between the short side surfaces is, and the area of the joint is maximized when the length of each side is the same. The larger the area of the junction, the more advantageous in terms of strength. The absolute value of the length of the long side and the short side and the ratio thereof are set according to the strength, the size of the opening, and other conditions required for the target building structure. However, since the present invention is a structure based on a honeycomb shape, it is advantageous because sufficient strength can be obtained even when the difference between the long side and the short side is relatively large, and the opening can be widened in such a case.

The tension material insertion hole is previously formed in the position shown by the broken line in each unit in FIG. 15 and FIG. A sheath (not shown) is buried in the tension member insertion hole. One tension member insertion hole penetrates the unit perpendicularly to any one joining surface in the unit. Thus, one unit has three tension inserting holes extending in three different directions (at an angle of 60 degrees to each other).

For example, as shown in FIG. 16, when the short side surfaces of the two units 2 (1) and 2 (2) are opposed to each other, the tension member insertion holes formed in both sides communicate with each other and face the unit 2 (1). One tension member insertion hole is formed which continues from the long side on the right side to the long side on the left side toward the unit 2 (2). In other words, the short side surfaces are brought into contact with each other so that the positions of the tension member insertion holes of the two units are matched with each other.

The tension member 21a is inserted through this tension member insertion hole to add post tension, and both ends thereof are fixed by using a pair of fixing fixtures 22a and 22a, thereby providing the units 2 (1) and (2 (2)). Can be firmly bonded. In addition, the unit 2 (2) is joined to the unit 2 (3) by the second tension member 21b and the fixing holes 22b and 22b. Further, the unit 2 (2) is joined to the unit 2 (5) 'included in the adjacent hexagonal lattice by the third tension member 21c' and the fixing holes 22c ', 22c'.

In this way, when the units are connected to each other, one unit is joined to three neighboring panel units by three tension members 21a, 21b, and 21c 'extending in three different directions. To become a strong joint. This makes it possible to construct an architectural structure having a main frame that is strongly joined in a honeycomb shape.

Referring again to FIG. 15, in the main frame in which the structural units are arranged in a virtual honeycomb shape having the hexagonal grid H1 as a unit grid, the two upper and lower sides of the hexagonal grid H1 are arranged in parallel in the horizontal direction. Here, in the vertical direction, when looking at each of the two columns arranged vertically in the m and n rows, each unit in each row is arranged in a zigzag and connected by a rigid joint. This form is inclined pillars arranged in a zigzag pattern by connecting the vertices (h3 ", h2, h3, h4, h3 ', h4') of the plurality of hexagonal grids H1 arranged in the vertical direction (for example, In the case of Example 8, it has the same function as that of the inclined column, and has a structure that is easy to convert the vertical load and the horizontal load into the axial force. It becomes a firm structure.

In the honeycomb structure using the unit 2, the panel unit located at each vertex of the hexagonal lattice H1 where the stress is most concentrated is a planar member having a width, and the structure is very strong against stress because there is no joint at this part. . The junction is located at the midpoint of each side of the hexagonal lattice H1, and this part is advantageous because the stress is small.

The structure of the unit 2 shown in FIG. 15 and FIG. 16 is demonstrated in detail using FIG. 17 and FIG. 17 is an external perspective view of the unit 2. 18 is a (A) front view, (B) top view, (C) Y-Y sectional view, and (D) Z-Z sectional view. The unit 2 is a PC panel manufactured using a given formwork.

As shown to FIG. 17 and FIG. 18, the front panel surface 2i and the back panel surface 2j (lower side in FIG. 17) are hexagons of the same shape, and each edge | side is mutually arrange | positioned in parallel. For example, the short side 2a1 of the panel surface 2i and the short side 2a2 of the panel surface 2j are parallel to each other and the long side 2f1 of the panel surface 2i and the long side 2f2 of the panel surface 2j. Are parallel to each other. The distance between the panel surface 2i and the panel surface 2j becomes the thickness of the unit 2.

In the panel surfaces 2i and 2j, short sides and long sides are alternately arranged. For example, in the panel surface 2i, it arrange | positions in order of the short side 2a1, the long side 2d1, the short side 2b1, the long side 2e1, the short side 2c1, and the long side 2f1. Short sides are the same length, and long sides are also the same length.

Moreover, it is provided with six side surfaces 2a, 2d, 2b, 2e, 2c, and 2f which are perpendicular to the panel surfaces 2i and 2j and extend between the corresponding sides. The side surfaces 2a, 2b, 2c extending between the short sides become the joining surfaces as short sides. Sides 2d, 2e, 2f extending between the long sides thereof are long sides and are non-bonded surfaces.

Further, as shown in Fig. 18A, the tension member insertion holes 2a3 (between the short side 2a and the long side 2e) between the sides facing each other among the six sides, (2b3) (short side 2b ) And the long side 2f), 2c3 (between the short side 2c and the long side 2d) are formed, respectively. Each tension member insertion hole 2a3, 2b3, 2c3 is respectively perpendicular to an opposite pair of sides. It is preferable that each tension member insertion hole 2a3, 2b3, 2c3 is opened in the substantially center of each side surface. In the front view, any tension member insertion hole passes through the center of the unit and the angle γ between each other is 60 degrees. The three tension member insertion holes appear to intersect when viewed from the front, but are formed at positions not overlapping each other within the thickness range of the unit as shown in Figs. 18 (B) and (C). Above all, from the balance point of view, it is preferable that all the tension material insertion holes are located as close to the center as possible within the thickness range of the unit.

The dimension of each site | part of the unit 2 is set suitably according to the conditions, transport conditions, etc. which are required for the building structure to be built.

19 is an external perspective view of the unit 5 corresponding to a special case of the unit 2. The part corresponding to the unit 2 shown in FIG. 17 is represented with the same code | symbol. Compared to the unit 2 of FIG. 17, the pair of panel surfaces 5i and 5j differ in that the regular hexagons, that is, the lengths of the six sides are the same. When joining the units 5 together, for example, one side surface 5a, 5b, 5c may be used as a joining surface, and the other points are the same as the unit 2 shown in FIG.

Although not shown, a hexagon in which two long sides of the three long sides of the panel surface are the same length and the other one is a different length may be used as a modification of the unit 2.

Fig. 20A is an external perspective view showing the structural unit 2A joinable with the unit 2 of Fig. 17 as one embodiment of the structural unit used when the virtual honeycomb shape has a curved surface or bending. 20A shows an external perspective view.

In the unit 2A, one short side surface 2Ac forms some angle β1 from the direction C perpendicular | vertical with respect to the panel surfaces 2Ai and 2Aj. By using such a unit 2A, a curved honeycomb structure can be constructed.

20 (B) shows another structural panel unit 2A (2) having the same shape as the unit 2A (1) shown in (A), each of the short sides 2Ac (1) and 2Ac ( 2)) is a rear view (inner surface side of the main frame) in a state of being joined to each other and Fig. 20 (C) is a top view. As shown in the top view, each of the panel surfaces 2Aj (1) and 2Aj (2) of the two units 2A (1) and 2A (2) joined are at an angle of 180 ° -2β1. Bends are formed. If such joining is continued, a curved surface can be formed.

However, the angle β1 is a very small angle, and the tension member is inserted into both the units 2A (1) and 2A (2), and the post-tension is applied and fixed in the same manner as the unit 2 shown in FIG. The same bond strength can be obtained. Therefore, the short side surface 2Ac serving as the joining surface can be said to be almost perpendicular to the panel surfaces 2Ai and 2Aj even if there is an inclination, and the tension material insertion hole 2Ac3 opening in the short side surface 2Ac also has a side face. It is almost vertical.

Fig. 21A is a front view showing the unit 2B joinable with the above-described unit 2 as another embodiment of the structural unit used when the virtual honeycomb shape has a curved surface or bending. (B) has shown the top view.

As shown in Fig. 21 (A) and (B), the front panel surface of the unit 2B is divided into two surfaces 2Bi1 and 2Bi2 which form an angle β2 with each other on the boundary of the linear curved portion 2Bk. Is done. The same applies to the rear panel surface. That is, the unit 2B is bent at the bent portion 2Bk. By joining the units 2B having such curved portions 2Bk to each other, a curved main frame can be constructed. For example, when the main frame is parallel to the vertical direction also in the curved portion as in the cylindrical tube furniture shown in Fig. 13A, the unit 2B is disposed so that the bent portion 2Bk is parallel to the vertical direction. The direction of the bent portion 2Bk is arranged so as to correspond to the direction in which the surface of the main frame is bent. In the example shown in figure, the position of the bend portion 2Bk is centered, but may be shifted left or right. Moreover, this curved unit 2B can also be used for the bent portion (for example, the corner of the tube furniture shown in FIG. 7) where two planes in the main frame intersect. In addition, the magnitude | size of angle (beta) 2 may be the grade which has no trouble in joining two units 2B with the tension | tensile material which added the post tension, or joining unit 2B and another joinable unit.

In addition, when the curved unit 2B is used, not only a curved surface that bends in one direction but also a curved surface that bends in the opposite direction can be formed continuously. For example, it is a curved surface when viewed from the top.

By using a combination of the flat unit 2 shown in FIG. 17 and the curved unit 2B shown in FIG. 21, a main frame having a flat portion and a curved portion can be freely constructed.

Example  3

Another embodiment of a building structure having a main frame in which a structural unit is arranged and connected in a virtual honeycomb shape will be described with reference to FIGS. 22 to 25.

22 is a front view showing a part of the main frame 103 of the building structure constructed using the structural unit. For example, it is a part of tube furniture similar to FIG. 7 (A) mentioned above. FIG. 23 is a partially enlarged perspective view of the main frame 103 of FIG. 22.

The main frame shown in FIG. 22 shows the structural unit 5 shown in FIG. 2 with respect to the lower part K1 with respect to the virtual honeycomb shape which makes a hexagonal grid H2 (shown by a thick one-dot dashed line) shown in FIG. It is constructed by arranging and connecting, and constructing by arranging and connecting the structural unit 4 shown in FIG. 2 with respect to the upper part K2. The unit 5 is a unit whose panel surface is a regular hexagon as described as one modification of the unit 2 in FIG. 19 described above. The unit 4 is a unit which made the non-joined surface in the unit 5 the concave curved surface.

In the lower portion Kl, six units 4 are arranged to include the positions of the vertices h1 to h6 of the hexagonal lattice H2, and two neighboring units face each other with the midpoints of the sides and the joint surfaces facing each other. It is joined. The joined surfaces s1 to s6 intersect each side vertically. The six units 4 are thereby connected in a ring shape. In the upper part K2, six units 5 are similarly arranged and connected on the hexagonal grid H2. The unit 4 and the unit 5 are different in shape of the non-bonded surface, but can be joined to each other because the position and shape of the bonded surface are common.

In the lower portion K1, a hexagonal opening portion Wf is formed in the center portion of the hexagonal grid H2, and in the upper portion K2, an almost circular opening portion Wg is formed in the center portion of the hexagonal grid H2. . In the boundary portion, an opening Wh having an irregular shape is formed. The unit 4 has a narrower panel area (ie, a smaller volume) than the unit 5, and the opening Wg is wider than the opening f by that amount. Small volume of the unit means light weight and low concrete amount. It is preferable to use a unit having a smaller volume as the upper layer system is lighter because it is suitable for an upper layer system with a relatively low load and a burden on the lower layer system. On the other hand, by using a unit having a sufficient amount of concrete in the lower floor system, it is possible to support a heavy load from the upper floor system.

22 and 23, the tension material insertion hole is previously formed in the position shown by the broken line inside each unit. A sheath (not shown) is embedded in the tension member insertion hole. One tension member insertion hole penetrates the unit perpendicularly to any one joining surface in the unit. Thus, one unit has three tension inserting holes extending in three different directions (at an angle of 60 degrees to each other).

For example, as shown in FIG. 23, when the joining surfaces of the unit 4 (1) of 2 and the unit 4 (2) oppose, the tension material insertion hole formed in both will communicate. The tension member 21a is inserted through this tension member insertion hole to add post tension, and the ends thereof are fixed by using a pair of fixing units 22a and 22a to fix the unit 4 (1) and the unit 4 (2). ) Can be firmly bonded. In addition, the unit 4 (2) and the unit 4 (3) are joined by the second tension member 21b and the fixing holes 22b and 22b, and the unit 4 (3) and the unit 4 (4) are The third tension member 21c and the fixing members 22c and 22c are joined together.

When units are connected in this way, one unit is joined to three neighboring units, respectively, by three tension members 21a, 21b, and 21c extending in three different directions, so that each joining portion is prevented from rotating. To become a strong joint. This makes it possible to construct an architectural structure having a main frame that is strongly joined in a honeycomb shape.

The structure of the unit 4 shown in FIG. 22 and FIG. 23 is demonstrated in detail using FIG. (A) is a front view, (B) is a top view, (C) is an external perspective view.

As shown in FIG. 24, the front panel surface 4i and the back panel surface 4j are the same shape. The contour shape of the panel surfaces 4i and 4j is formed by three opposite sides of the regular hexagon and three concave curves therebetween. The flat side surfaces 4a, 4b, 4c including the three sides of the straight line serve as joining surfaces with neighboring units. The concave curved surfaces 4d, 4e, 4f between the bonding surface and the bonding surface are non-bonding surfaces.

Also, the tension member insertion hole 4a3 (between the joining surface 4a and the concave curved surface 4e) between the side surfaces facing each other among the six sides, 4b3 (between the joining surface 4b and the concave curved surface 4f) , 4c3 (between the joining surface 4c and the concave curved surface 4d), respectively. Each tension member insertion hole 4a3, 4b3, 4c3 is perpendicular | vertical to the joining surface 4a, 4b, 4c, respectively. It is preferable that each tension member insertion hole 4a3, 4b3, 4c3 is opened in the substantially center of each joining surface and a concave curved surface. In the front view of FIG. 24 (A), any tension material insertion hole passes through the center part of a unit, and the angle (gamma) which mutually forms is 60 degree | times. Moreover, as shown to FIG.24 (B) and (C), each tension material insertion hole is formed in the position which does not overlap with each other in the thickness range of a unit. In particular, from the balance point of view, it is preferable that all the tension member insertion holes are located as close to the center as possible within the thickness range of the unit.

The dimension of each part of the unit 4 is set suitably according to the conditions, transport conditions, etc. which are required for the building structure to be built.

FIG. 25A shows a unit 4A which is an embodiment of a structural unit used when the virtual honeycomb shape has a curved surface or bending, and is a front view of a state in which it is joined to the unit 4 described above. (B) is the top view.

As shown in Figs. 25A and 25B, the front panel surface of the unit 4A is divided into two surfaces 4Ai1 and 4Ai2 which form an angle β with each other on the basis of the linear curved portion 4Ak. Is done. The same applies to the rear panel surface. That is, the unit 4A is bent at the bent portion 4Ak. By joining the unit 4A having such a bent portion 4Ak with the unit 4 described above, a curved main frame can be constructed. When the unit 4A is further connected to the unit 4A, the degree of warpage increases. For example, even when the main frame is parallel to the vertical direction in the curved portion as in the cylindrical tube furniture shown in Fig. 13A, the unit 4A is disposed so that the bent portion 4Bk is parallel to the vertical direction. The direction of the bent portion 4Ak is arranged so as to correspond to the direction in which the surface of the main frame is bent. In the example shown in figure, the position of the bent portion 4Ak is the center, but may be shifted to the left or the right.

Moreover, this curved unit 4A can also be used for the bending part (for example, the corner part of the tube furniture shown in FIG. 7) where two planes in a main frame cross | intersect. In addition, the magnitude | size of the angle (beta) shall be the grade which is satisfactory in the joining of two units 4A comrades with the tension material which added the post tension, or joining the unit 4A and other joinable units.

In addition, when the curved unit 4A is used, not only the curved surface bent in one direction but also the curved surface bent in the reverse direction can be formed continuously. For example, it is a curved surface when viewed from the top.

Example  4

With reference to FIGS. 26-31, the other Example of the building structure which has a main frame which arrange | positioned and connected the structural unit in a virtual honeycomb shape is demonstrated.

26 is a front view showing a part of the main frame 104 of the building structure constructed using the structural unit. For example, it is a part of tube furniture similar to FIG. 7 (A) mentioned above. FIG. 27 is a partial perspective view of a main frame composed of the same unit as the main frame 104 of FIG. 26.

In the lowest part K1 of the main frame shown in FIG. 26, the virtual honeycomb shape which makes a hexagonal grid | lattice H2 (it shows with a thick one-dot dashed line) as a unit grid | lattice was shown by FIG. 4 by the arrangement pattern B shown in FIG. The structural unit 8 is arranged. On the lowermost part K1, the 2nd part K2, the 3rd part K3, and the uppermost part K4 which consist of structural units of a different shape, respectively, are continuously constructed. The structural unit 13, the structural unit 14, and the structural unit 15 which are respectively used for the second part K2, the third part K3, and the uppermost part K4 are all the structures shown in FIGS. 3 and 4. It is a variant similar to unit 7.

The units 8, 13, 14 and 15 are all arranged at positions where the hexagonal lattice H2 comprises a pair of two vertices neighboring each other. For example, the unit 8 of the lowermost part K1 has (8 (1)) occupying one vertex of the hexagonal lattice near the vertex h1 and the unit 8 (2) is the vertex h2 and ( occupies h3, and unit 8 (3) occupies one vertex of pair h4 and the adjacent hexagonal lattice, and unit 8 (4) occupies (h5) and (h6). Each unit arrange | positioned in this way makes each side surface of upper right, upper left, lower right, and lower left a joining surface. Two units adjacent to each other are joined to each other by opposing respective joining surfaces, and the four units 8 are connected in a ring shape. These joints are strong joints. Each of these joined four faces s1, s3, s4, s6 intersects with either side of the hexagonal lattice H2. The sides of the hexagonal lattice H2 also exist for the unit 13 in the second portion K2, the unit 14 in the third portion K3, and the unit 15 in the uppermost portion K4. The lengths are different but the arrangement and joining form of the units is the same. The units 8, 13, 14, and 15 have different shapes of the non-bonded surfaces of the panel surfaces, respectively, but can be joined to each other because the positions and shapes of the bonded surfaces are common.

Similarly to the embodiment shown in FIG. 26, the shape of the hexagonal lattice, which is the unit lattice of the virtual honeycomb shape, may be deformed as it goes from below to upward. The shapes are different but the individual hexagonal grids are symmetrical. And in the part which moves from one shape to a different shape, the hexagonal grating of a shape which is not up-down symmetry exists.

In the lowermost portion K1, a rectangular opening Wh is formed in the center portion of the hexagonal grid H2, and in the second portion K2, an almost elliptical opening portion Wi is formed in the center portion of the hexagonal grid H2. In the third portion K3, an almost rhombic opening Wj is formed in the center portion of the hexagonal grid H2, and in the uppermost portion K4, the rhombic opening portion Wk is formed in the center portion of the hexagonal grid H2. Is formed. The lower the panel area of the unit from the lowermost part K1 to the uppermost part K4, the narrower the panel area of the unit (that is, the smaller the volume) and the wider the opening. Small volume of the unit means light weight and low concrete amount. It is preferable to use a unit having a smaller volume as the upper layer system is lighter because it is suitable for an upper layer system with a relatively low load and a burden on the lower layer system. On the other hand, the lower floor system can support the heavy load from the upper floor system by a unit having a sufficient amount of concrete.

In FIG. 26 and FIG. 27, the tension material insertion hole penetrates previously in the position shown by the broken line inside each unit. A sheath (not shown) is embedded in the tension member insertion hole. One end of one tension member insertion hole is opened in any one joining surface, and the other end is opened in any one non-joining surface. Thus, one tension unit has four tension member insertion holes extending in four different directions.

For example, as shown in FIG. 27, when one unit 8 opposes the joining surface of the upper left side to the joining surface of the lower right of the unit 13 on the upper left side, the tension material insertion hole formed in both will communicate. The tension member 21a is inserted into this tension member insertion hole to add post tension, one end of which is fixed using the fixing unit 22a at the lower side of the unit 8, and the other end is fixed to the fixing unit at the upper side of the unit 13. Are settled by using.

The second tension member 21b is inserted into the tension member insertion hole of the unit 8 and the lower left unit 8, and one end thereof is fixed using the fixing unit 22b on the upper side of the unit 8, and the other end is lower left. In the lower side of the other unit 8 of the fixing unit 22b.

The third tension member 21c is inserted into the tension member insertion hole of the unit 8 and the other lower right unit 8, one end of which is settled by the fixing unit 22c at the upper end of the unit 8, and the other end is lower than the other lower right side. The lower side of the unit 8 is fixed by the fixing tool 22c.

The fourth tension member 21d is inserted into the tension member insertion hole of the unit 8 and the upper right unit 13, one end of which is fixed by the fixing unit 22d at the lower side of the unit 8, and the other end is upper right. It is fixed by the fixing means 22d in the upper side of the unit 13.

All the units shown in Fig. 27 are joined by the tension member to which the post tension is added in the same manner. Since one unit is joined to four units neighboring each other by four tension members 21a, 21b, 21c, and 21d extending in four different directions, each joint is prevented from rotation and becomes a strong joint. This makes it possible to construct an architectural structure having a main frame that is strongly joined in a honeycomb shape.

In the main frame shown in Figs. 26 and 27, although the tension material insertion hole communicated between the two units is not necessarily linear, embedding the sheath in a curved shape in the PC panel is generally performed.

28 is an external perspective view of each unit shown in FIGS. 26 and 27, wherein (A) is a unit (8), (B) is a unit (13), (C) is a unit (14), and (D) is a unit (15). ) to be.

In addition, the tension member insertion hole 8a3 is disposed between the joint surface 8a and the non-joint surface 8g, and the tension member insertion hole 8b3 is disposed between the joint surface 8c and the non-joint surface 8g. A tension member insertion hole 8c3 is formed between the joining surface 8e, and a tension member insertion hole 8d3 is formed between the joining surface 8d and the non-joining surface 8e, respectively. And it is preferable that the tension material insertion holes 8a3 and 8b3 open in the substantially center of the non-joining surface 8g. It is preferable that the tension member insertion holes 8c3 and 8d3 be opened almost at the center of the non-joining surface 8e.

When viewed from the panel surface 8i side, the tension member insertion holes 8a3 and 8d3 are seen to intersect and the tension member insertion holes 8b3 and 8c3 are seen to intersect. However, each tension member insertion hole is formed in the position which does not overlap with each other within the thickness range of the unit 8. As shown in FIG. First of all, from the balance point of view, it is preferable that all the tension material insertion holes are located as close to the center as possible within the thickness range of the unit.

As shown to FIG. 28 (B), the unit 13 is provided with joining surface 13a-13d and non-bonding surface 13e-13h, and a joining surface is common with the unit 8 of (A), and is a non-joining surface.

For example, the units 8, 13, 14, and 15 shown in FIG. 27 have a large and heavy weight as a general PC panel when one unit is assigned to one tier, and thus the efficiency of manufacturing, transportation and assembly There is a risk of inhibiting. Therefore, as shown in FIG. 29, the main frame 105 constructed as shown in FIG. 27 by securing the efficiency of manufacturing, transportation and assembly by making the half unit which divided each unit into two at the center part as a manufacturing unit of a PC panel is shown in FIG. The same function as the main frame 104 by 8, 13, 14 and 15 can be accomplished. Since two half units which form one unit are the same shape, the formwork at the time of manufacture should just be one kind.

The integrated panels of the half units 8m and 8n correspond to the unit 8 of FIG. 27 and the integrated panels of the half units 13m and 13n correspond to the unit 13 of FIG. 27 and the half unit 14m. ) And 14n correspond to the unit 14 of FIG. 27, and the integrated panel of the half unit 15m and 15n corresponds to the unit 15 of FIG. The half panels are joined at the same time by joining the integrated panels in which the half units are bonded together using the four tension members 21a to 21d in the same manner as the units 8, 13, 14 and 15 in FIG.

The tension member insertion holes 8ma3, 8mb3, 8mc3 and 8md3 are opened in the division surface 8t, and the tension material insertion holes 8na3, 8nb3, 8nc3 and 8nd3 are opened in the division surface 8u. By contacting the dividing surface 8t of the half unit 8m and the dividing surface 8u of the half unit 8n to abut, the PC panel of the same shape as the unit 8 is formed, and each tension material insertion hole also communicates with a unit The arrangement is the same as that of the tension member insertion hole (8). As shown in FIG. 29, the half-units 8m and 8n are firmly joined by inserting and tensioning a tension member through these connected tension member insertion holes to fix and post-tension. The same applies to the half units of the units 13, 14 and l5 in Figs. 30 (B) to (D).

31 and 32 show units 8A, 13A, 14A and 15A which are one embodiment of the structural unit used when the virtual honeycomb shape has a curved or bent. 31 (A1) and (A2) are front and top views of the unit 8A in a state of being joined to the unit 8 described above, and (B1) and (B2) are joined to the unit 13 described above.

The same applies to the rear panel surface. That is, the unit 8A is bent at the bent portion 8Ak. By joining the unit 8A having such a bent portion 8Ak with the unit 8 described above, a curved main frame can be constructed. When the unit 4A is further connected to the unit 8A, the degree of warpage increases. For example, when the main frame is parallel to the vertical direction also in the curved portion as in the cylindrical tube furniture shown in Fig. 13A, the unit 8A is disposed so that the bent portion 8Ak is parallel to the vertical direction. The direction of the bent portion 8Ak is arranged so as to correspond to the bending direction of the surface of the main frame. In the example shown in figure, the position of the bent portion 8Ak is centered, but may be shifted left or right.

Moreover, this curved unit 8A can also be used for the bending part (for example, the corner part of the tube furniture shown in FIG. 7) where two planes in a main frame cross | intersect. In addition, the magnitude of the angle β is such that the joining between the two units 8A by the tension member to which the post tension is applied, or the joining between the unit 8A and other joinable units is satisfactory.

In addition, when the curved unit 8A is used, not only a curved surface that bends in one direction but also a curved surface that bends in the opposite direction can be formed continuously. For example, it is a curved surface when viewed from the top. The same applies to the units 13A, 14A, and 15A.
