Description

  The present invention relates to a covering material mounting structure for mounting a covering material such as a heat shield sheet or a waterproof sheet to a roof material, and a construction method of the covering material mounting structure.

  Conventionally, the roof of a building has been provided with a covering material that covers the roof, such as a heat shield sheet that suppresses the temperature rise of the roof or naturally cools the roof. As an example of the covering material, there is a heat shield sheet as in Patent Document 1. As shown in FIG. 13, the heat shield sheet 91 is a rectangular sheet having heat shield characteristics. On the peripheral edge of the heat shield sheet 91, eyelets 91a for attaching to the roofing material 92 are provided at a predetermined pitch. The roof material 92 is a long plate material formed by bending a steel plate. The roof is formed by combining these roof materials 92,.

  The heat shield sheet 91 is attached to a covering material attachment structure 901 constructed by combining single tubes 910. In order to attach the covering material attachment structure 901 to the roof material 92, a bolt weld clamp 920 is used. As shown in FIGS. 14A and 14B, the bolt weld clamp 920 includes a fixing member 921 having a concave portion formed on the inner surface in accordance with the contact surface of the single pipe 910, and one end side of the fixing member 921. A movable member 922 that is pivotally connected to the stationary member 921, a closing bolt 923 that is pivotally attached to the other end of the fixed member 921, and closes the stationary member 921 and the movable member 922, and a screw that is screwed to the closing bolt 923. And a fastening nut 924 that is tightened with the gap between the fixed member 921 and the movable member 922 approached and a fixing bolt 925 that is welded to the outside of the fixed member 921.

  For example, when the covering material attachment structure 901 is attached to a stacked (bolt type) folded plate roof, as shown in FIG. 13, a sword tip bolt 93 is provided to protrude upward from the roof material 92 at a predetermined pitch. (Normally a cap is attached). This sword tip bolt 93 is provided to connect the tight frame 95 fixed to the ceiling beam 94 and the roofing material 92. As shown in FIG. 14 (a), the covering material mounting structure 901 is configured such that a fixed bolt 925 of a bolt weld clamp 920 is coupled to a sword tip bolt 93 via a high nut 930, and each single pipe 910 is connected to the top of the roof material 92. To fix. The covering material mounting structure 901 includes a first single pipe 911 fixed to a position on the roofing material 92 provided with the tight frame 95, and the first single pipe 911 connected to the first single pipe 911. The second single tube 912 fixed in a direction orthogonal to the second single tube 912 is constructed.

  The bolt weld clamp 920 is also used for attachment to the covering material attachment structure 901. First, the bolt welding clamp 920 is fixed at a position on the single pipe 910 corresponding to the position of the eyelet 91 a of the heat shield sheet 91. At this time, the bolt weld clamp 920 is attached so that the fixing bolt 925 protrudes upward with respect to the single pipe 910 as shown in FIG. The eyelet 91a of the heat shield sheet 91 is inserted into the fixing bolt 925, and the heat shield sheet 91 is attached to the covering material mounting structure 901 with a nut 940, packing 950, and the like.

  However, since the position where the tight frame 95 is provided differs depending on the building being constructed, the position where the sword bolt 93 protrudes from the roof material 92 also differs depending on the building. That is, the position of the first single pipe 911 that fixes the covering material mounting structure 901 to the roof material 92 is determined by the position of the tight frame 95 of the building. The position of the eyelet 91a of the heat shield sheet 91 is also determined and cannot be easily changed.

  Therefore, as shown in FIG. 13, when the position of the eyelet 91 a of the heat shield sheet 91 does not correspond to the position of the first single tube 911, the second eyeglasses 91 a are aligned with the position of the eyelet 91 a of the heat shield sheet 91. If the third single pipe 913 is further passed between the single pipes 912, the bolt weld clamp 920 is fixed to the third single pipe 913, and the heat shield sheet 91 is not attached, the heat shield sheet 91 is attached to the roof. The material 92 could not be attached.

  Next, the construction method of the covering material mounting structure 1 according to this embodiment will be described. First, the 1st fixing member 4 is arrange | positioned in several places along the flow direction X of the roofing material 92 (1st arrangement | positioning process). Specifically, the first fixing portion 42B is coupled to a sword tip bolt 93 provided at a position where the first fixing member 4 is fixed. Then, the rail main body 43 is placed on the fixture main body 46 of the fixing portion 42, and a bolt is inserted through the second coupling portion 48 and the connection portion 45 of the rail main body 43 to tighten and couple the nut.

  After the first arrangement step, the second fixing member 5 is arranged at a specific position between the first fixing members 4 in the direction intersecting with the first fixing member 4 (the row direction Y of the roof material 92). (Second arrangement step). The 2nd fixing member 5 is arrange | positioned according to the position of the eyelet 91a of the heat shield sheet 91 to attach.

  After the second arranging step, the first fixing member 4 and the second fixing member 5 are connected by the connecting member 6 (connecting step). Specifically, the contact plates 62Aa of the second contact portions 62A and 62B of the connecting member 6 are inserted into the rail 41 of the first fixing member 4 (in the first posture P1), and the first contact is made. The mounting surfaces 64A and 64B of the contact portions 61A and 61B are mounted. Further, the contact plates 62Aa of the second contact portions 62A and 62B of the connecting member 6 are inserted into the rail 51 of the second fixing member 5 (in the first posture P1), and the second fixing member 5 The mounting surfaces 65A and 65B of the second contact portions 62A and 62B of the connecting member 6 are mounted on the rail 51.

  Then, by rotating the bolt 63Aa of the operating members 63A and 63B, the second contact portion 62A is also driven by the rotation of the bolt Aa in the axial direction, from the first posture P1 to the second posture P2. Rotate. That is, since the first corner portion C1 of the second contact portion 62A is formed in an arc shape, the second contact portion 62A is allowed to rotate without interfering with the inside of the rails 41 and 51, and is formed in a substantially right-angle shape. The second corner C2 (as it is) interferes with the inside of the rails 41 and 51 to restrict the rotation and prevent rotation. Further, by rotating the bolt 63Aa, the nut 63Ab is fastened to the bolt 63Aa, and the first contact portion 61A and the second contact portion 62A approach each other, and the protrusions 44, The connecting member 6, the first fixing member 4, and the second fixing member 5 are coupled to each other by sandwiching 54.

  The attachment members 3,... Are arranged at positions on the appropriate rails 41, 51 for attaching the covering material 92 after the connecting step (third arrangement step).
