[0012] In the fixture according to the present invention, the legs and holder can be made of SPHC (hot-rolled mild steel), stainless steel, or aluminum plate with a thickness of approximately 2.0 to 3.2 mm, and the center link can be an extruded aluminum member. When the materials are in contact with each other, one or both of them are insulated before joining to prevent corrosion. When the insulating material is a steel plate, it is preferable to apply a coating, and when the insulating material is aluminum, it is preferable to apply an anodizing treatment. The fixture according to the present invention can be applied to roofs and walls constructed by arranging multiple building material panels, each with a joint at each end in the width direction, side by side and placing cover caps between the joints of each building material panel to connect the building material panels to each other via the cover caps. However, the fixture can also be applied to other roofs and walls as long as the legs of the fixture can clamp a portion of the roof or wall, and is not limited to the illustrated example.

[0013] Reference numeral 1 in Figures 1 to 10 denotes a pair of legs that can hold on both sides a part of a roof, for example, a cover cap C that is placed between joints S of building panels T. The legs 1 have hook-shaped pieces 1a that hook onto the lower edge of the cover cap C in the width direction (see Figures 9, 10, and 11).

[0014] 1 to 10, reference numeral 2 denotes a pair of holders provided at the upper ends of the pair of legs 1, sign Reference numeral 3 denotes a center piece that is disposed between the pair of holders 2 and is clamped and fixed to the pair of holders 2 via a through bolt 4 .

[0015] The holder 2 can be configured to include a plate-like upright wall 2a that rises from the upper end of the leg 1 and can abut against the end face 3a of the center link 3, and a pair of plate-like side walls 2b that are connected to both widthwise edges of the upright wall 2a and located on the side faces 3b of the center link 3. A reinforcing portion M may be provided between the holder 2 and the leg 1, partially protruding outward to increase bending strength.

[0016] The center piece 3 is configured to have a top wall 3c that forms a mounting surface for an object to be installed, at least one recess 3e that has an open end 3d formed in the top wall 3c and extends toward the upright wall 2a of the holder 2, and an object-fixing bolt 3f that passes through the open end 3d and is disposed in the recess 3e to fix an object (not shown) placed on the top wall 3c to the top wall 3c. A flange 3c1 can be provided on the widthwise edge of the top wall 3c, the lower surface of which abuts against the upper end surface of the side wall 2b of the holder 2 to position the center piece 3 relative to the holder 2.

[0017] The recess 3e of the center piece 3 has open ends and can be used as a grooved guide that holds the installed object fixing bolt 3f slidably and unable to pull out, and has a groove 3g formed at its bottom that is open at both ends and extends toward the upright wall 2a of the holder 2 to enable efficient drainage of rainwater. The recess 3e allows the installed object fixing bolt 3f to be moved appropriately along the recess 3e, so that even if the position of the installed object fixing bolt 3f is deviated from the fixing hole (not shown) provided in the base of the installed object, the installed object fixing bolt 3f can be reliably inserted into the fixing hole provided in the base of the installed object by fine adjustment by moving the installed object fixing bolt 3f along the recess 3e.

[0018] It is particularly preferable that the recess 3e extends toward the upright wall 2a of the holder 2. In this case, the open end 3d also extends toward the upright wall 2a of the holder 2 in the same manner as the recess 3e. Therefore, when the mounting device according to the present invention is applied to the roof of a building, installation It is possible to restrict the movement of the fixing bolt 3f in the eaves or ridge direction, and when applied to the wall of a building, installation The vertical movement of the fixing bolt 3f can be restricted, and in either case, the load in the flow direction can be borne by the main body of the fixture.

[0019] 1 to 10, reference numeral 5 denotes an opening provided in each holder 2 through which the through bolt 4 passes, and reference numeral 6 denotes a communication hole provided in the center piece 3. The communication hole 6 faces the opening 5, and the through bolt 4 that passes through the opening 5 is held in the center piece 3.

[0020] 9 and 10, which is constructed by arranging a plurality of building panels T (sandwich-type panels having outer and inner skin materials made of metal plate material with a heat insulating layer between the outer and inner skin materials) side by side and connecting the building panels T to each other via cover caps C between the joints S of each building panel T. To install a fixture according to the present invention on the roof of a building as shown in FIGS. 9 and 10, as shown in the upper diagram of FIG. 11, loosen the nuts on the through bolts 4 so that the spacing L between the hook-shaped pieces 1a of the legs 1 is greater than the width dimension W of the cover caps C. With this state maintained, the fixture is placed on the top plate C1 of the cover cap C as shown in the lower diagram of FIG. 11. Next, tighten the nuts on the through bolts 4 until the upright wall portions 2a of the holder 2 abut against the end faces 3a of the middle pieces 3.

[0021] When the nut of the through bolt 4 is tightened so that the upright wall portion 2a of the holder 2 abuts against the end face 3a of the middle link 3, the mutual spacing L of the hook-shaped pieces 1a of the leg portion 1 becomes smaller than the width dimension W of the cover cap C, and the stopper function of the middle link 3 prevents the nut from being tightened any further. The mounting fixture is fixed and held in place by the cover cap C with a constant clamping force, and there is no risk of deformation or damage to the component parts due to excessive tightening of the nut.

[0022] Moreover, at this time, the end faces 3a and side faces 3b of the center piece 3 come into close contact with the upright wall portions 2a and side wall portions 2b of the holder 2 on a total of six surfaces, so the posture of the mounting fixture is stabilized.

[0023] The center piece 3 can be an extruded aluminum product, but it is also possible to use an assembled structure formed by joining each component by welding or the like, and it is not limited to an extruded aluminum product.

[0024] The fixture of the present invention basically comprises a pair of legs provided with a holder, and a center piece (including a bolt 3f for fixing the installation object) that is clamped and fixed to the holder via a through bolt. ) This structure requires fewer parts than conventional fixtures, and not only can simplify the structure of the fixture itself and reduce its weight, but also makes it easier to install the fixture. to It also becomes easier to handle.
