Description

  The present invention relates to a connection structure that constitutes a truss structure that supports a large structure such as a solar cell module in which a plurality of solar cell panels are arranged in a flat plate shape, and a truss structure that includes the connection structure.

  2. Description of the Related Art Conventionally, solar cell devices that generate power using a plurality of solar cell panels are known. A commercially available solar cell panel generates about 200 w of electricity per sheet (size is about 1.4 to 2.0 m × 0.8 to 1.1 m). In order to generate power with a solar panel as a business, it is necessary to generate at least 10 kW, and therefore, at least about 50 solar panels are required. However, the weight per solar cell panel is about 10 to 20 kg. In the case of a solar cell module (large structure) in which about 50 solar cell panels are arranged in a flat plate shape, about 500 kg to 1 ton per module. It is. For this reason, the load applied to the support means for supporting the solar cell module is large, and the support means needs to be strong enough to withstand this load. Although a patent application has been filed for the support means for supporting the solar cell panel (for example, Patent Document 1), no patent application related to the present invention has been filed.

(Connecting structure 100)
As shown in FIGS. 1 to 3, the vicinity of one end 110 of the four diagonal members 106 is positioned on the diagonal member-side pressing plate 116, and a spacer 112 is disposed on the vicinity of one end 110 of the four diagonal members 106. Positioned, the vicinity of one end 108 of the four string members 104 is positioned on the spacer 112, and the string member side pressing plate 114 is positioned on the vicinity of the one end 108 of the four string members 104. At this time, the positions of the four through holes 144 (shown in FIG. 5) of the oblique material side pressing plate 116, the positions of the four through holes 140 (shown in FIG. 5) of the spacer 112, and the four chord members The positions of the through holes 134 (shown in FIG. 5) 104 and the positions of the four through holes 142 (shown in FIG. 5) of the chord material side pressing plate 114 are made to coincide with each other in plan view. Also, the positions of the four through holes 144 (shown in FIG. 5) of the diagonal material side pressing plate 116, the positions of the through holes 136 (shown in FIG. 5) of the four diagonal materials 106, and the four spacers 112. The positions of the through holes 140 (shown in FIG. 5) and the positions of the four through holes 142 (shown in FIG. 5) of the chord material side pressing plate 114 are made to coincide with each other in plan view. Next, as shown in FIG. 1 and FIG. 3A, the four bolts 122 are the four through holes 142 of the chord material side pressing plate 114, the four through holes 134 of the chord member 104, and the spacer 112. The four through holes 140 and the four through holes 144 of the diagonal material side pressing plate 116 are respectively penetrated, and the nuts 124 are fastened to the four bolts 122, respectively. Further, as shown in FIGS. 1 and 3B, four bolts 126 are provided with four through holes 142 in the chord material side pressing plate 114, four through holes 140 in the spacer 112, and four oblique holes. The through holes 136 of the material 106 and the four through holes 144 of the diagonal material side pressing plate 116 are respectively penetrated, and the nuts 128 are respectively fastened to the four bolts 126. In this way, the connection structure 100 is formed. A plurality of connection structures 100 are formed.

  Here, by fastening the nut 124 to the bolt 122, the vicinity of the one end 108 of the string material 104 is sandwiched between the string material-side pressing plate 114 and the spacer 112 as shown in FIG. Further, the entire slope 148 of the diagonal member 106 is sandwiched between the spacer 112 and the diagonal member side pressing plate 116. The diagonal member 106 is not sandwiched between the spacer 112 and the diagonal member side pressing plate 116 in the vicinity of the bolt 122 and the nut 124. That is, the diagonal member-side pressing plate 116 is formed with a protruding portion 117 that protrudes to the outer periphery 121 of the diagonal member-side pressing plate 116 with respect to the inclined surface 148 of the diagonal member 106 in a cross-sectional view (cross section taken along line AA). Is done. By tightening the nut 124 on the bolt 122, the protruding portion 117 is pressed by the nut 124 in a direction adjacent to the spacer 112. The protrusion 117 is loaded with a moment M1 in the direction adjacent to the spacer 112 (counterclockwise in FIG. 3A), and is bent slightly elastically deformed in the direction adjacent to the spacer 112. Therefore, the movement of the inclined surface 148 of the diagonal material 106 in the direction in which the diagonal material 106 is separated from the diagonal material-side pressing plate 116 (the positive direction of the X axis in FIG. 3A) is caused by the bending portion of the diagonal material-side pressing plate 116. It is regulated by. That is, the movement of the diagonal member 106 in the positive direction of the X axis is restricted. Such an action occurs in the two diagonal members 106 adjacent to each other in FIG. 1 by tightening the nut 124 to the bolt 122 that penetrates the through hole 134 of the single string member 104. The movement of the diagonal member 106 in the negative direction of the X-axis is regulated by contact of the four inclined surfaces 148 of the diagonal member 106 as shown in FIG. As described above, the movement of the four diagonal members 106 in the direction of separating or approaching from the diagonal member-side pressing plate 116 is restricted. Even if there is a gap between the bolt 120 and the through hole 140 or the through hole 144, the movement of the four diagonal members 106 in the direction of separating or approaching from the diagonal member side pressing plate 116 is restricted, and the spacer 112. In addition, looseness of the four diagonal members 106 with respect to the diagonal member-side pressing plate 116 or the like does not occur.

  Similarly, as shown in FIG. 3B, in the chord material side pressing plate 114, a protruding portion 115 that protrudes to the outer periphery 121 of the chord material side pressing plate 114 is formed with respect to the inclined surface 146 of the chord material 104. The For this reason, the protrusion 115 is separated from the chord material side pressing plate 114 of the four chord materials 104 by an action in which a moment M2 is applied in a direction adjacent to the spacer 112 (clockwise in FIG. 3B). Movement in the approaching direction is restricted, and play of the four string members 104 with respect to the spacer 112 and the string member side pressing plate 114 does not occur. As described above, there is no backlash with respect to the spacers 112 and the like of the four string members 104 and the four diagonal members 106, and the four string members 104 and the four diagonal members 106 are firmly connected to each other. Become.
