  Hereinafter, the present invention will be described in more detail with reference to the examples of the drawings. In FIG. 1 to FIG. 3, the three-dimensional structure is installed and used so as to form a roof of an outdoor pool, for example, by being supported by a support 14. A structure near the corner of the solar power generation apparatus A in which the solar panel 11 is installed on the truss structure 1 is shown. FIGS. 4 to 10 show the structure of the joint portion in the three-dimensional truss structure 1. FIG. 12 shows members of the three-dimensional truss structure 1.

  The photovoltaic power generation apparatus A has a four-way diagonal member 4b joined at one end in the longitudinal direction to the three-dimensional truss structure 1 and joined at the other end in the longitudinal direction to form a number of dormitory frames 2 on the truss structure 1. A solar panel is placed on the three-dimensional truss structure 1 by projecting and placing the solar panel 11 so as to cover the panel light-receiving surface in series with an arbitrary inclined surface of the dormitory frame 2 as a panel light-receiving surface. 11 is arranged in series in one direction in the XY direction and arranged in parallel in the other, and the solar power generation device A is installed and used as an independent structure supported by the column 14 for forming the roof of the outdoor pool. In addition to the above, as shown in FIGS. 15 to 19 to be described later, it is assumed that various installation forms are adopted, including urban areas in densely populated areas, installed regardless of the installation location, Possible as much as possible Some as having been.

  In the present example, the three-dimensional truss structure 1 uses the chord member 3a and the diagonal member 4a, and the joining pieces 5a to 5c arranged at both ends in the longitudinal direction are collectively arranged at each joining intersection, and the intermediate spacer 6a. In addition, a basic joining structure is adopted in which two bolts 9 are used at each joining intersection together with the upper and lower seat plates 7a, whereby two-surface shear joining is performed using ordinary bolts, and Two-surface frictional bonding is made possible by using high-strength bolts, and the structural strength of the three-dimensional truss structure 1 is ensured as high as possible.

  That is, the string member 3a and the diagonal member 4a of this example are each provided with a length of about 1 to 2 m between the joining intersections, and are provided with the joining pieces 5a to 5c protruding horizontally at both longitudinal ends thereof, For example, the example illustrated in FIG. 11 and FIG. 12 is used, and at this time, the joining pieces 5a and 5b of the string material 3a are different from each other for the string material 3a. The joint piece 5c of the material 4a is made to have a joint structure with the two bolts 9 by using one common type.

  That is, one of the two types of the joining piece 5a in the string member 3a is fully projected with two bolt insertion holes 8 in the plane so that the projecting width is the same area as the spacer 6a to the seat plate 7a. The other joining piece 5b is made to pass through one bolt insertion hole 8 in the surface so that the protruding width is 1 of the flat rectangular seat plate 7a to spacer 6a. / 2 is a semi-protruding rectangular joining piece for overlapping butt. In addition, the joining piece 5c of the diagonal member 3a has a bolt insertion hole 8 formed in one plane in the surface, and the tip is cut off so as to form a triangle from the half projecting position while projecting the entire projecting width. It is a planar pentagonal joining piece for a butt. At this time, the spacer 6a and the seat plate 7a are each of the planar rectangular shape, and two bolt insertion holes (not shown) are similarly provided in the plane thereof.

  The joining pieces 5a to 5c of the chord material 3a and the diagonal material 4a are the four pieces of joining material 5a to 5c of the chord material 3a and the diagonal material 4a from each of the four directions. In the material 3a, the joint pieces 5b for semi-projection butting are arranged in one layer with their tips butted against each other, and a total of three layers so that the joint pieces 5a for full projection polymerization are arranged in two layers. On the other hand, in the diagonal member 4a, the joining pieces 5c are superposed on the joining pieces 5c of the pair of adjacent oblique members 4a, and the inclined sides at the tips of the pair of joined joining pieces 5c are mutually connected. There is a group of two layers.

  The joining pieces 5a, 5b of the chord material 3a from the four directions forming the group of the three layers and the joining pieces 5c of the diagonal material 4a from the same four directions forming the group of the two layers are arranged in the middle. For example, the seat plates 7a are arranged above and below the joint pieces 5a to 5b that are collectively arranged via the two spacers 6a, and these are integrally joined by fastening the bolt 9 and the nut 10 together. It is. The bolt insertion holes 8 of the joining pieces 5a to 5c in the chord member 3a and the diagonal member 4a, the spacer 6a, and the bolt insertion holes (not shown) of the seat plate 7a are arranged so as to be concentrically arranged in the assembled state. In the state of being assembled, the diagonally arranged material 3a, the spacer 6a, the chord material 4a, and the bolt insertion holes 8 of the lower surface or the upper surface seat plate 7a are inserted into the bolt insertion holes 8 from the upper surface or the lower surface seat plate 7a side. By inserting the bolts 9 and fastening the nuts 10 to the protruding bolt shafts, the bolts can be joined and the bolts can be firmly joined.

  FIG. 6 shows a three-dimensional truss in which the joining piece 5c of the diagonal member 4a is joined to the upper part of the joining pieces 5a and 5b of the string member 3a, that is, the string member 3a is located lower and the oblique member 4a is located higher. The joints on the lower surface side of the structure 1 are shown. The structure of the joints on the upper surface side of the three-dimensional truss structure 1 with the string material 3a as the upper part and the diagonal member 4a as the lower part is a form in which FIG. As a thing, the bolt joining is performed.

  At this time, a joining piece 5c of an oblique member 4b that forms a framing frame 2 described later is further polymerized at the joining portion of the chord member 3a and the oblique member 4a, and joining is performed using a common joining means. This point will be described later in relation to the formation of the berlin frame 2.

  As shown in FIGS. 1 to 3, the three-dimensional truss structure 1 has a frame that forms two front and back surfaces of a chord-like string material 3a having a planar square arrangement, and the same plane with the arrangement angle shifted by 45 degrees. A truss having a box shape in which a diagonal grid 4a is provided with an intermediate frame formed by a grid-shaped diagonal material 4a having a square arrangement, and the two surfaces of the string material 3a are flat grids. As a structure. At this time, by joining the joining intersections using the two bolts 9, the bolt joining can be made into the above-mentioned strong two-surface shearing or friction joining, respectively. It is assumed that its structural strength is highly secured.

  The three-dimensional truss structure 1 is further used as a structural base, and a diagonal member 4b in four directions is joined to one side thereof, that is, the upper surface of the three-dimensional truss structure 1, and the above-mentioned offset made of the diagonal material 4b in four directions is provided. The ridge-like frame 2 is arranged so as to protrude, and in this example, the ridge-like frame 2 is arranged in the plane with the string material 3a in the plane square arrangement in the three-dimensional truss structure 1 as a base. It is assumed that each of the string members 3a having a square arrangement is arranged so as to be adjacent to each other in the in-plane XY direction of the three-dimensional truss structure 1 by projecting.

  In this example, the dormitory frame 2 has the four-way diagonal member 4b joined to the three-dimensional truss structure 1 at one end in the longitudinal direction at the other end in the longitudinal direction, that is, the apex of the dormitory frame 2. The projecting arrangement is performed so that a frame surface forming an isosceles triangle is formed between the diagonal member 4b from each of the two directions joining the apexes and the base of the plane square by joining at the position. is there.

  The diagonal member 4b of the dormitory frame 2 has the length of the diagonal member 4a of the three-dimensional truss structure 1 shortened, and the arrangement angle thereof is 45 in the three-dimensional truss structure 1 in the present example. The angle is set to be gentler than the angle of about 50 degrees, and is set to an angle of, for example, about 30 degrees among the angles of 30 to 60 degrees from the horizontal position suitable for the installation of the solar panel 11. Although the joining pieces 5c horizontally projecting at both ends in the longitudinal direction of the shortened diagonal member 4b have a projecting angle from the steel pipe portion somewhat different from that of the three-dimensional truss structure 1, the joining pieces 5c The piece 5c is also used for superposition butt joining, and includes the projecting width, the planar shape, and the bolt insertion hole 8, and is configured in the same manner as the diagonal member 4a constituting the three-dimensional truss structure 1.

  The diagonal member 4b of the dormitory frame 2 has one end in the longitudinal direction joined to the four joints of the chord member 3a and the diagonal member 4a of the three-dimensional truss structure 1 constituting the installation structure base, and the longitudinal direction It arrange | positions so that it may incline and stand toward the said vertex of an other end, and it shall carry out similarly to joining of the diagonal material 4a in the solid truss structure 1 in this vertex, as shown in FIG. The joining pieces 5c of the diagonal member 4b are superposed adjacent to each other, and the inclined sides of the superposed tips are abutted with each other, so that the joining pieces 5c from the four directions are arranged in a two-layer superposition manner. The joining piece 5c of the diagonal member 4b, the spacer 6a, and the seat plate 7a are superposed to form two bolts 9 from the lower seat plate 7a side, the bolt insertion holes 8, the spacer 6a, and the upper seat plate of each joining piece 5c. 7a is inserted through the bolt insertion holes 8 at two locations, And fastening the nut 10 in seat plate 7a side surface, it is subjected to the junction of the vertex as a joining point of intersection. At this time, when joining the vertices, the three-dimensional truss structure 1 is located on the upper lower surface of the solar panel 11 to reinforce and connect the dormitory frame 2 so as to connect the vertices of the panel light receiving surface. The chord material 3b for inter-vertex construction similar to the chord material 3a is additionally arranged, and the chord material 3b is a joining piece, in this example, the semi-projecting joining piece 5b is formed as a single layer. Is placed on the seat plate 7a in a similar manner, and a support fitting 12 to be described later for installing the solar panel 11 is placed as a seat plate of the string material 3b. The joining is performed simultaneously with the material 4b.

  On the other hand, the diagonal member 4b of the dormitory frame 2 and the three-dimensional truss structure 1 are joined in this example, and at the intersection of the chord member 3a and the diagonal member 4a on the upper surface of the three-dimensional truss structure 1 Simultaneously with the joining of the string material 3a and the diagonal material 4a. That is, at the time of the joining, in accordance with the joining structure of the string member 3a and the diagonal member 4a of the three-dimensional truss structure 1, the joining piece 5c in the spacer member 6a and the oblique member 4b of the dormitory frame 2 is further polymerized. It does not interfere with the joining with the two bolts 9 which are inserted through these bolt insertion holes, for example, upward.

  However, in this example, in addition to the spacer 6 a used for the three-dimensional truss structure 1, the diagonal member 4 b of the dormitory frame 2 and the three-dimensional truss structure 1 are joined together by 4 Two additional spacers 6b for this bolt are used. In this example, the use of the additional spacer 6b prevents the bolts used to join the three-dimensional truss structure body 1 from joining at the joining intersections and increasing the length thereof. Thus, for example, the joint intersection is divided into two parts in the upper and lower directions, so that the joint is integrally performed using four bolts 9 in total, and in this example, further sunlight is used. By using a relatively short bolt 9 similar to other ones, it is possible to avoid the lengthening of the bolt by simultaneously joining the support fittings 12 to be described later for installing the panel 11. It is made strong and can be surely made into a bolt joint.

  The spacer 6b additionally used in this example has four through holes concentrically, that is, two bolt head accommodation holes in addition to the two bolt insertion holes 9 of the three-dimensional truss structure 1. The two types of spacers 6b are used for the string material and the diagonal material, and the two types of spacers 6b are joined by using two in total, one each. That is, as illustrated in FIG. 5, at the joining intersection, the chord member 3b and the diagonal member 4b of the dormitory frame 2 are joined. In this example, the support metal fitting 12 is further superposed. In addition, the former is joined with two bolts 9 upward and the latter is joined with two bolts 9 downward so that the joint of the string member 3a and the diagonal member 4a formed with the three-dimensional truss structure 1 is the other of the two parts. At the same time, the two bolts 9 facing downward are used so as to integrally join both of the two divided parts at the same time, and the bolts are integrally joined.

  The simultaneous integral bolting of the diagonal member 4b of the dormitory frame 2 at the junction of the string member 3a and the diagonal member 4a of the three-dimensional truss structure 1 is performed by dividing the two divided ones of the string member 3b and the diagonal member 4b. As in the three-dimensional truss structure 1, a pair of adjacent ones and a joining piece 5a to 5c arranged in abutment between the pair are polymerized with a seat plate 7a on the lower surface and two spacers 6b on the upper surface, The bolt heads of the two bolts 9 are accommodated in the bolt head accommodation holes of the upper spacer 6b, and the nuts 10 are inserted through the bolt insertion holes 8 of the lower spacer 6b, the diagonal member 4a and the lower seat plate 7a. By fastening the two bolts downward, the bolt heads of the upper two bolts 9 are accommodated in the bolt head accommodation holes of the lower spacer 6b, and the upper two bolts 9 are placed on the upper side thereof. Joining piece 5a of string material 3b 5b, the upper two spacers 6b, the joining piece 5c of the diagonal member 4b in the dormitory frame 2 arranged by superposition and butting as in the three-dimensional truss structure 1, and the bolts of the upper seat plate 7a By inserting the insertion hole 8 and tightening the nut 10 in the same manner, the two bolts are joined upward.

  In this way, by forming the dormitory frame 2 on the three-dimensional truss structure 1 with the diagonal members 4b from each of the four directions, the surface of the three-dimensional truss structure 1, in this example, the upper surface thereof, A rectangular pyramid having a square chord 3a as a base is formed to form a frame surface arranged in a matrix in the vertical and horizontal directions, that is, densely in the XY direction, and the four surfaces of the dormitory frame 2 are formed. The planes forming the isosceles triangles are arranged so as to be continuous with each other in the adjacent XY directions at an angle of 30 to 60 degrees, and in this example, 30 degrees.

  The surfaces forming the four isosceles triangles of the dormitory frame 2 are used as panel light-receiving surfaces for receiving sunlight on the solar panel 11, and the solar panel 11 is inclinedly installed on the panel light-receiving surface. Yes, at this time, the solar panel 11 is installed in an inclined manner by using the means for joining the diagonal members 4b in the four directions at the joint position of the diagonal member 4b in common, thereby receiving the panel light of the dormitory frame 2 The solar panel 11 is integrally fixed to the surface by using the joint means for the diagonal member 4b in common. The support member 12 is joined to the support member 12 together with the diagonal member 4b, and a pair of parallel purlin members 13 are arranged in series on the support member 12 with the panel light receiving surface directed in one direction XY. Opposing upper and lower 2 of the optical panel 11 There as being performed by fixing the.

  That is, the solar panel 11 is inclined so that a large number of the solar panel 11 are juxtaposed on the panel light-receiving surface, is arranged in series in one XY direction, and is arranged in parallel in the other direction. One of the dimensions of the opposing two sides of the rectangle, that is, the height thereof can be substantially equal to the length of the diagonal member 4b, but the width is not necessarily the bottom of the isosceles triangle, that is, the chord member of the three-dimensional truss structure 1 Since it cannot be equivalent to the joining interval of 3a, by using the purlin material 13, it is possible to make an inclined installation close to or adjacent to each other without generating a gap between the solar panels 11. is there.

  The support fitting 12 is, for example, a fixed piece having two bolt insertion holes (not shown) through which two bolts 9 are inserted, and a purlin support supporting the main piece 13 upright so that the main piece 13 can be supported on the fixed piece. In this example, the support fitting 12 has a C-shaped cross section in which the purlin support pieces are arranged on both sides of the fixed piece. 2 for connecting the intersection of the string member 3a and the diagonal member 4a in the three-dimensional truss structure 1 having a V-shaped cross section by placing the purlin support piece on one side of the fixed piece. There is a kind to use.

  As shown in FIGS. 4 and 7, the support metal 12 is joined to each joint of the diagonal member 4 b on the panel light-receiving surface at the apex of the dormitory frame 2, as shown in FIGS. 4 and 7. In this example, the fixing piece of the support metal fitting 12 is placed on the joining piece of the string material 3b for erection between the vertices in the upper level, and the two upward bolts 9 from the lower side of the seat plate 7a are attached. The fixing piece is inserted into the bolt insertion hole, and the nut 10 is fastened and joined to the fixing piece. As a result, the base material support pieces on both sides of the fixing piece of the support metal 12 are inclined upward and are offset. Above the apex of the ridge-like frame 2, it stands up at right angles to the panel light receiving surface.

  Further, as shown in FIG. 5 and FIG. 8, at the joint intersection of the string member 3a and the diagonal member 4a of the three-dimensional truss structure 1, similarly, a fixing piece of the support metal fitting 12 is mounted on the seat plate 7a on the upper surface. The upward bolt 9 from the spacer 6b is inserted into the bolt insertion hole of the fixed piece, and similarly, the nut 10 is fastened on the fixed piece to join the fixed piece. The main material support piece is inclined so as to incline forward, and is also erected at a right angle to the panel light-receiving surface above the joining intersection of the chord material 3a and the diagonal material 4a.

  As shown in FIGS. 4 and 5, the purlin member 13 includes, for example, fixing pieces that are fixed to the bottom surface of the solar panel 11 and the purlin member support piece of the support bracket 12, and similarly processes the steel plate. In this example, the support metal fitting is used in common with the above two types of support metal fittings 12 having an L-shaped cross section in which these fixing pieces are arranged orthogonally. This is one type.

  The purlin member 13 is fixed to the bottom surface of the solar panel 11 and the purlin member support piece of the support fitting 12 at each joint intersection by fixing brackets such as bolts and nuts. The purlin member 13 is fixed to the support fitting 12 arranged at the apex of the dormitory frame 2 with the purlin member 13 parallel to the solar panel 11, two adjacent to the upper back surface, and one on the lower back surface. A total of three books are fixed, and the main building material 13 is in contact with the main building material support piece, and this is performed using a fixing bracket. It is located on the top side of the string material 3b on the top side of the string material 3b in parallel with the chord material 3b for inter-vertex construction arranged at the vertex, It intersects with the chord 3a at right angles and is located at the same upper position.

  Since the photovoltaic power generation apparatus A of this example formed in this way is arranged in series in the XY direction on one side of the building-like frame 2 arranged on the three-dimensional truss structure 1 and in parallel on the other side, A large number of solar panels 11 installed according to the number of frames 2 can be used for solar power generation, and the remaining three surfaces of the dormitory frame 2 are opened, thereby ensuring ventilation. It is possible to avoid the wind pressure from acting on the solar panel 11.
