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 by which the clamping tool was fulcrum-coupled, and becomes a structure clamped with respect to a goby part, this kind of thing is both clamped 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 a case where a pair of sandwiching members are connected and combined and installed on the roof, the connecting and sandwiching operations (rotation operations in the example of the above-mentioned patent document) are smoothly performed on the connecting portions of the respective sandwiching members. Because it has a predetermined clearance for it, so it may be one-side tightening (non-uniform tightening), and when both clamping members are connected and clamped to the bolt body, both are uniform and balanced There were times when it was not in a state. In particular, when both sandwiching members have different shapes, the possibility is high.

  Further, in the above-mentioned patent document, a pair of sandwiching members are connected to each other by fulcrums between upper plates so as to be freely opened and closed, and the sandwiching pieces are brought close to each other by the lever principle to be sandwiched between the bolt bodies. Since the connection is only a fulcrum, there is a possibility that the bolt body may be pinched in a slightly inclined state.

  Therefore, when both sandwiching members are attached in a poorly balanced state, the inclination increases when a lateral force is applied due to the load on the roof attachment (various equipment / members), and the bolt body There is a possibility that the attachment on the roof may come off and the fixture on the roof will come out. In particular, in the case where the leg piece is attached without being attached to the top of the peak portion of the corrugated roof, the inclination is increased by a slight force in the lateral direction, so that the leg piece is more unstable.

  In this way, the on-roof fixture composed of two clamping members is not likely to come out easily even when a load in the vertical direction (force that pulls from directly above) is applied, but is likely to wobble in the lateral direction. The problem was inherent.

  The present invention has been proposed in consideration of such problems, and its purpose is to stabilize the balance between the two clamping members that are sandwiched between the bolt bodies protruding from the corrugated roof in a uniform state. An object of the present invention is to provide an on-roof fixture that can maintain the above condition.

  The on-roof fixture A of the present invention configured as described above is used by being attached to the folded plate roof Y in the following manner.

  First, the shaft portion of the mounting bolt 3 is fitted into the notch recess 11b of the pedestal portion 11 of one clamping member 10, and the fall prevention plate 4 is attached to the shaft portion protruding upward and temporarily fixed. . Next, after the shaft portion of the tightening bolt 25 is passed through the shaft holes 12a and 12a of the leg pieces 12 and 12 of the two clamping members 10 and 10, the tightening nut 26 is inserted from the distal end side of the tightening bolt 25. The guide protrusion 10a and the insertion opening 10b of the two sandwiching members 10 and 10 are lightly and male-coupled (the tip of the guide protrusion 10a is inserted into the insertion opening 10b) and temporarily fixed. The clamp 1 is folded from the upper side of the bolt body B protruding from the folded roof Y so that the bolt body B is inserted between the meshing recesses 14a and 14a of the half cylinder pieces 14 and 14. It is mounted on the top surface of the top Y1a of Y (see FIGS. 3A and 3B).

  Next, when the tightening bolt 25 and the tightening nut 26 that have been temporarily fixed are tightened, the two guide protrusions 10a and 10a are inserted into the corresponding through-opening portions 10b and 10b, and the two pedestal portions are inserted. 11 and 11 adhere closely without a gap. At the same time, both the leg pieces 12 and 12 come close to each other by the tightening force by screwing, the two half-cylinder pieces 14 and 14 come close to each other, and both the meshing recesses 14a and 14a surround the male screw part B1 of the bolt body B around it. The female screw portions 14b and 14b of the half cylinder pieces 14 and 14 and the male screw portion B1 of the bolt body B are engaged with each other to form a screwing relationship (FIG. 4A). (Refer FIG.4 (b)).

  Further, the ring body 30 is fitted into the cylindrical body 15 formed by the two half-cylinder pieces 14 and 14, the protrusion insertion notch 31a is aligned with the protrusion 14d, and the ring body 30 is positioned at the lowermost end (pinching). The attachment of the clamping tool 1 is completed by moving the ring body 30 down and shifting the positions of the protrusion 14d and the protrusion insertion notch 31a (see FIG. 3A).

  Various devices and members can be attached on the pedestal portion 11 of the on-roof fixture A thus attached to the folded plate roof Y (see FIG. 4B).

  In the construction procedure example described above, the two sandwiching members 10 and 10 are temporarily attached to the folded plate roof Y (see FIGS. 3A and 3B). After the clamping members 10 and 10 are separated and placed on the folded plate roof Y with the bolt body B interposed therebetween, the both clamping members 10 and 10 may be coupled while sliding.

  According to the roof mounting tool A shown above, each of the two sandwiching members 10 and 10 has a guide protrusion piece 10a and a through-opening opening 10b integrally and has a male-female integrated structure. The both can be combined in a well-balanced and uniform state and sandwiched between the bolt bodies B protruding from the folded plate roof Y. As described above, since the bolt body B can be clamped in a well-balanced state, a stable state can be maintained even when an external force is applied, and the clamp tool 1 can be prevented from coming out of the bolt body B.

  Further, as shown in the figure, if the guide protrusion 10a and the insertion opening 10b are formed in a symmetrical position across the notch recess 11b at the center of the edge, the two sandwiching members 10 and 10 are formed. It can be set as the same shape, As a result, the two clamping members 10 and 10 can be comprised by one type of components.

  In addition, since one guide member is provided with two guide protrusions and the other support member is provided with two penetration openings corresponding to the guide protrusions, it can be connected by two sets of male and female connections. Although a certain degree of coupling stability can be obtained, the two sandwiching members have different shapes from each other, and therefore, a uniform coupling similar to that of the on-roof fixture A of the present embodiment cannot be expected.

  Further, in the present embodiment, a structure in which a guide protrusion piece 10a and a through-opening portion 10b are formed in the opposing piece 11a of the pedestal portion 11 of the sandwiching member 10 at a position near the notch recess 11b. Therefore, it is very easy to perform a joining operation by penetration.

  Further, in the present embodiment, the clamping member 10 is attached in a state where the lower end of the leg piece 12 and the outer surface of the base piece 13a of the clamping piece 13 are in contact with the top Y1a of the folded plate roof Y. Therefore, the stable state on the folded-plate roof Y can be maintained reliably. In addition, the thing of the grade which only the lower end of the leg piece 12 contacts the top part Y1a may be sufficient. Further, in order to maintain more stable stability, the base piece 13a may be fixed to the top Y1a with an adhesive tape or the like.

  Further, since the ring body 30 is fixed to the half cylinder piece 14 in a state where the bolt body B is sandwiched, the pair of sandwiching pieces 13 and 13 are attached to the bolt body by the fitting of the ring body 30. There is no risk of leaving B. Further, the ring body 30 is fitted to the bolt body B of the clamping tool 1 due to the clamping action by the fastening of the leg piece 12 and the fitting (engaging) action by the meshing concave portion 14a of the half cylinder piece 14. The clamping force can be increased.

  Furthermore, since the protrusion 14d is formed on the outer peripheral body portion 14c of the half cylinder piece 14, if the ring body 30 is inserted into the cylindrical body 15 and rotated to shift the position, the protrusion 14d It is possible to prevent the ring body 30 from slipping upward.
