Description

  TECHNICAL FIELD The present invention relates to a fixing structure for a peripheral portion of a membrane material in a structure in which a membrane material is stretched on the upper surface of a frame made of a frame structure or the like, which is constructed on a platform of a station, an outdoor exhibition hall, a passage, and the like, and a construction method thereof .

  In recent years, membrane materials have been used as roofing materials and the like that cover station platforms, outdoor exhibition halls, and passageways.

  In these membrane structures, cables (ridge cables) are attached to both side edges of the membrane material, and the cable is fixed to a frame or a foundation to introduce tension into the membrane material and the cable (for example, Patent Document 1 below). -4 etc.). With such a membrane structure, when building a station platform, an outdoor exhibition hall, a passage, etc., on the upper surface of the frame made of a frame structure etc., both side edges are folded back along the longitudinal direction to form a loop part, A structure is adopted in which a membrane material through which a cable is inserted is stretched in the loop portion, and the cable is fixed to the frame at a predetermined interval position.

Here, as a means for fixing the cable inserted in the both side edges of the membrane material to the frame at a predetermined interval position, the cable is mainly divided into a cable division type for fixing each cable for each span, and a cable. There is a continuous cable type that is continuously provided along both side edges of the membrane material and fixed slidably without restricting movement in the longitudinal direction of the cable.

  In the cable division type, since the cable is divided for each span length, the handling of the cable is easy and the workability is excellent, and it is easy to cope with an accuracy error in the production, construction, or construction of the frame, the membrane material, or the cable. In addition, even if the tension of the membrane material decreases over time, it is easy to re-introduce the tension with the cable, and even if a tension difference occurs between adjacent cables, the cable does not move. While there is an advantage, there is a drawback that the structure of each fixing unit becomes large.

  In the case of the continuous cable type, it is assumed that the cable is applied to a small-scale structure. Since the cable is continuous and the tension is diffused, the load on the fixing unit is reduced and the fixing structure can be made compact. On the other hand, the larger the structure, the more inconvenient to handle the cable and the more difficult it is to fix the cable in place. In addition, when elongation occurs in the film material due to stress relaxation or the tension decreases with time, it is difficult to re-tension and adjust the tension for each span. Furthermore, when the membrane material receives an uneven distribution load such as wind pressure, the cable moves (slides) and does not recover. Further, due to the movement (sliding) of the cable, stress concentration may occur in the film material, and there is a problem that it is difficult to cope with an accuracy error in manufacturing and construction of the frame, film material, or cable.
