Description

  The present invention relates to an on-roof fixture that is sandwiched between bolt bodies protruding from the top of a corrugated roof and is mounted on the roof.

  In general, various devices and parts such as TV antennas, air conditioners, solar panels, heat shield sheets, etc. are placed on the top of corrugated roofs such as folded plate roofs (square corrugated roofs) and round corrugated roofs. Conventionally, various on-roof fixtures for attaching various devices and members on the roof have been proposed (see, for example, Patent Document 1).

  In particular, at the top of the peak portion of the corrugated roof where the peaks and valleys are alternately continuous, the overlapped portion of the overlapping roof materials is connected and fixed by screwing the bolt body and nut. In the thing, the male thread part of the bolt body for roof material connection which penetrated from the lower part of the roof and protruded on the roof was sandwiched and fixed by sandwiching pieces whose ends are opposed to each other. On-roof fixtures have also been proposed.

  This on-roof fixture extends from the lower ends of both leg pieces by tightening both leg pieces with fastening bolts and nuts that penetrate the leg pieces of the sandwiching tool formed in a substantially portal shape in the lateral direction. The both sandwiched pieces are sandwiched between bolt bodies. Therefore, since the front end of the sandwiching piece is fixed in a state of being bitten into the thread groove of the bolt body, there is no possibility that the on-roof fixture is easily detached.

  Moreover, although the thing of patent document 1 is comprised from a pair of clamping member with which the clamping tool was fulcrum-coupled, it has a structure clamped with respect to a goby part. Even when applied to a structure in which the piece is clamped to the bolt body, similarly, there is no possibility that the on-roof fixture is easily detached.

Japanese Patent No. 3368374

  However, in the case of the on-roof mounting tool that is mounted by being clamped to the bolt body, there are the following problems.

  FIG. 11 is a schematic explanatory view showing two examples of attaching the conventional roof mounting fixture to the corrugated roof, which is attached by clamping, and FIG. 11 (a) is a side edge of the corrugated roof Y. FIG. 11 (b) shows an example in which the goby part D formed by the gourd joint structure at the top part Y1a of the mountain part Y1 is attached to the leg part E1, and FIG. This is an example of pinching. Both are examples in which the heat shield sheet 110, which is one of the on-roof fixtures (various devices / members), is fixed above and attached to each of the on-roof fixtures. An on-roof fixture (clamping tool 100) is used. In addition, the example of attachment of the on-roof fixture shown in FIGS. 11A and 11B is different in the attachment mode (direction) with respect to the top Y1a.

  When the thermal insulation sheet 110 is fixed and stretched to a plurality of sandwiching tools 100 as shown in the figure, for example, when snow is accumulated on the thermal insulation sheet 110, it is arranged on both sides of the thermal insulation sheet 110 by the weight of the snow S. If the roof mounting fixture (the clamping tool 100) is pulled to the center, the clamping piece 101 clamped to the goby E or the bolt body B may be tilted up. Further, when the heat shield sheet 110 is dampened by rainwater or the like and then dried, the heat shield sheet 110 may contract, and in that case, the same phenomenon may occur.

  In this case, the pinching tool 100 attached to the goby portion E may be slightly displaced or tilted, but the upper portion of the goby portion E protrudes in the lateral direction, so that the pinching tool 100 comes out of the gouge portion E. Although there is almost no fear (see FIG. 11A), in the case where the bolt is attached to the bolt body B, the clamping tool 100 is gradually tilted by a strong pulling force, and the tip of the clamping piece 101 is the bolt body B. There is a possibility that the shaft portion B1 may come off while being lifted (see FIG. 11B).

  In addition, in the case of an on-roof fixture that is attached by being clamped to the bolt body B, a nut (not shown) for fastening the bolt body B needs to be disposed on the top surface of the top portion Y1a. In this case, the leg piece or the sandwich piece 101 is lifted from the top Y1a, and the sandwich tool 100 may be rotated or wobbled.

  Therefore, in the roof mounting tool of the type that is attached by being clamped to such a bolt body B, the structure is less likely to cause slack such as tilting, sliding up, rotation, wobble, etc. of the clamping tool due to external force. Things were needed.

  The present invention has been proposed in view of such circumstances, and its purpose is to maintain a stable state without the possibility of slipping or loosening of the sandwiching tool, and for a plurality of on-roof fixtures. An object of the present invention is to provide an on-roof fixture that does not cause the clamping tool to tilt or come off due to the load of the on-roof fixture attached on the roof.

  In order to achieve the above-mentioned object, the on-roof fixture according to claim 1 is provided with a substantially portal-shaped sandwiching tool provided with a pair of sandwiching pieces facing each other at the lower end, and the sandwiching tool. In the on-roof fixture that is adapted to clamp and fix the pair of sandwich pieces of the tool close to each other, and to the bolt body protruding from the top of the corrugated roof, further comprising a ring body for fixing the sandwich piece, A semi-cylindrical piece having meshing recesses facing each other is formed upright at the respective tip portions of the pair of sandwiching pieces, and the pair of semi-cylindrical pieces has a male threaded portion of the bolt body at both meshing recesses. The ring body is configured to be sandwiched and meshed, and a ring body is fitted on an outer peripheral body portion of the cylindrical body formed by clamping the half cylinder piece to the bolt body, and is fixed to the bolt body.

  The roof mounting tool according to claim 3, wherein the sandwiching tool is integrally formed including a leg piece formed by bending the sandwiching piece at the lower end and an upper plate having the leg piece at both ends, The pair of sandwich pieces are brought close to each other by tightening the pair of leg pieces.

  According to a fourth aspect of the present invention, the on-roof mounting tool is configured such that the sandwiching tool is formed by connecting a pair of sandwiching members in which the sandwiching pieces are bent at the lower ends thereof so as to be freely opened and closed.

  According to the on-roof fixture according to claim 1, since the ring body is fitted to the pair of half-cylinder pieces sandwiching the bolt body in a cylindrical shape, the pair of clamping pieces is formed by fitting the ring body. There is no fear of being separated from the bolt body, and the clamping force of the clamping tool to the bolt body can be increased in combination with the clamping action of the clamping piece and the retaining action by the meshing recess of the half cylinder piece. Therefore, there is no possibility that the sandwiching tool is displaced or loosened, and it is possible to maintain a stable state. In addition, the sandwiching tool tilts or falls off due to the load of the on-roof attachment mounted on the plurality of on-roof attachments. You can avoid fear.

  According to the on-roof fixture according to claim 2, since the protrusion is formed on at least one outer body of the half cylinder piece, the protrusion formed on the inner periphery of the ring body is inserted. If the ring body is fitted into the half cylinder piece by aligning the possible protrusion insertion notches, and then rotated to shift the position, the ring body can be prevented from coming out upward after fitting. .

  According to the on-roof fixture of claim 3, the sandwiching tool is integrally formed including a leg piece formed by bending the sandwiching piece at the lower end and an upper plate having the leg piece at both ends. Therefore, the clamping tool can be constructed in a sturdy and simple shape. Moreover, since it is integrally formed, there is little possibility that a deviation will occur between both sandwiched pieces.

  According to the on-roof fixture according to claim 4, the sandwiching tool is configured by opening and closing a pair of sandwiching members in which the sandwiching pieces are bent at the respective lower ends, Regardless of tightening, the clamping piece can be clamped to the bolt body with a labor-saving and simple operation.
