Description

  The present invention relates to an on-roof fixture that is attached to the top of a corrugated roof.

  Generally, various devices and members such as a television antenna, an air conditioner, a solar cell panel, a heat insulating sheet, etc. are disposed on the top surface of a corrugated roof such as a folded plate roof (angular corrugated roof) or a round corrugated roof. Conventionally, various on-roof fixtures for attaching these devices and members on the roof have been proposed (for example, see Patent Document 1).

  In particular, at the top of the peak portion of the corrugated roof in which the peaks and valleys are alternately continuous, the overlapping portion of the overlapping roof materials is connected and fixed by screwing upward bolts and nuts. In the roof, the roof has a structure in which the shaft portion of the upward bolt for connecting the roofing material that protrudes from the roof through the overlapped portion is sandwiched and fixed by sandwiching pieces with opposite ends. An upper fixture has also been proposed.

  This on-roof fixture is, for example, fastened to both leg pieces with tightening bolts and nuts penetrating laterally through both leg pieces of a sandwiching tool formed in a substantially portal shape, and facing from the lower ends of both leg pieces. It has a structure in which both of the sandwiching pieces extending to are clamped to the upward bolt. Therefore, since the front end of the sandwiching piece is fixed in a state of being bitten into the thread groove of the shaft portion of the upward bolt, there is no possibility that the roof mounting tool is easily detached.

Japanese Patent No. 3368374

  However, in the case of an on-roof fixture of a type that is attached by being clamped to an upward bolt, there are the following problems.

  FIG. 6 is a schematic explanatory view showing two examples of attachment examples of a conventional roof mounting fixture to be attached by corrugation to a corrugated roof. FIG. 6A is an example of sandwiching the goby portion 25 formed on the top portion 31a of the mountain portion 31 of the corrugated roof 30 to the leg portion 25a, and FIG. This is an example of clamping to the upward bolt 21. Both are examples in which the heat insulating sheet 110 is fixed and attached above each roof mounting tool 100, and both examples use the roof mounting tool 100 of the same type and the same structure.

  As described above, when the heat insulating sheet 110 is fixed and stretched around the roof-mounted fixtures 100, the heat insulating sheet 110 may be dampened by rainwater or the like, and then contracted when dried. Then, if the heat insulating sheet 110 is firmly fixed to the roof mounting tool 100, the roof mounting tool 100 disposed on both sides of the heat insulating sheet 110 is pulled to the center by the shrinkage of the heat insulating sheet 110, and There is a concern that the sandwiching piece 101 sandwiched between the portion 25 and the upward bolt 21 may slide up.

  In this case, although there is a possibility that some deviation occurs in the case attached to the goby portion 25, the upper part of the gouge portion 25 protrudes in the lateral direction, so that the roof mounting tool 100 is not likely to come out of the goze portion 25. (Refer to FIG. 6A.) In the case of mounting on the upward bolt 21, the roof mounting tool 100 is gradually tilted by a strong tensile force, and the tip of the sandwiching piece 101 pushes the shaft portion 21 a of the upward bolt 21. There is a possibility that it may come off while sliding up (see FIG. 6B).

  Therefore, the roof mounting tool 100 of the type that is mounted by being clamped to the upward bolt 21 as described above requires a structure that is mounted with a stronger clamping force than that to be mounted on the goby portion 25. .

  The present invention has been proposed in view of such circumstances, and the purpose thereof is a pinching piece that can be strongly attached to an upward bolt projecting from a top surface of a corrugated roof through a pedestal and fixed to the upward bolt. An object of the present invention is to provide an on-roof fixture that is not likely to come off due to external force.

In order to achieve the above object, an on-roof fixture according to claim 1 includes a plurality of substantially portal-shaped sandwiching tools having different dimensions, and each of the sandwiching tools has a pair of sandwiching tips facing each other. A pair of clamping pieces are provided in the lower part, and a pair of clamping pieces are brought close to each other and are sandwiched by upward bolts protruding from the top of the corrugated roof through the pedestal, and a plurality of clamping tools are nested. By including, the sandwiching pieces of each sandwiching tool are arranged in a plurality of stages in the vertical direction, and by the proximity of the sandwiching pieces, the tip of the bottommost sandwiching piece is connected to the top of the corrugated roof and the mountain seat The upper clamping piece is clamped to the shaft portion of the upward bolt, and the tip of the upper clamping piece is engaged with the outer peripheral surface of the shaft portion of the upward bolt. A locking recess that can be stopped is formed, and the plate piece is tilted upward and protruded at the center of the locking recess. Characterized in that it comprises a single, more becomes engaging portion and both the inner edge piece of the locking recesses disposed on both sides of the engaging protrusion.

  The roof mounting fixture according to claim 2 is provided with a waterproof packing between the top of the corrugated roof and the mountain seat, and the tip of the lowermost sandwich piece has a conflict with the waterproof packing. An avoiding packing accommodating recess is formed.

  The present invention has the following effects.

  That is, according to the roof mounting tool according to claim 1, by including a plurality of sandwiching tools in a nested state, the sandwiching pieces of each sandwiching tool can be arranged in a plurality of stages in the vertical direction, By the proximity of the pair of sandwiching pieces, the tip of the lowermost sandwiching piece is inserted between the top of the corrugated roof and the mountain seat, and the upper sandwiching piece is sandwiched between the shafts of the upward bolts. As a result, the clamping force is increased by the structure of clamping in a plurality of stages, and the clamping force can be firmly clamped to the upward bolt protruding from the top of the corrugated roof. Therefore, there is no possibility that the plurality of sets of sandwiching pieces sandwiched by the upward bolts will be detached from the upward bolts by an external force.

  Especially, it has a structure in which the tip of the lowermost sandwich piece is inserted between the top of the corrugated roof and the mountain seat. Since it is a structure, there is almost no possibility that a clamping tool will come off. Moreover, since it has the mounting structure which clamps an upper stage clamping piece to the axial part of an upward volt | bolt, the clamping by the lowest stage clamping piece can be supplemented.

Furthermore, since the on-roof fixture is configured by combining a plurality of sandwiching tools, it can also be used as an individual rooftop fixture if the sandwiching tools are separated separately.
In addition, a locking recess that can be locked to the outer peripheral surface of the shaft portion of the upward bolt is formed at the tip of the upper clamping piece. Therefore, if the clamping force is increased, the thread groove extends over the entire circumference of the shaft portion. Can be deeply inserted into the bolt and can be firmly fixed to the upward bolt, and the fixing by the lowermost sandwich piece can be sufficiently supplemented.

  According to the roof mounting fixture of the second aspect, the packing receiving recess that avoids the conflict with the waterproof packing interposed between the top and the mountain seat is formed at the tip of the lowermost sandwich piece. Therefore, even when the tip of the sandwiching piece at the bottom of the sandwiching tool is inserted between the top of the corrugated roof and the mountain seat, the tip of the waterproof packing is not likely to come into contact with the waterproof packing. Can be prevented from being damaged.

FIG. 3 is an exploded perspective view of a plurality of sandwiching tools constituting the roof mounting tool shown in FIG. 4 (a) and 4 (b) are partial cross-sectional front views showing a construction state of the on-roof fixture.

  The folded plate roof 30 used in the present embodiment is a roof in which the mountain portions 31 and the valley portions 32 are alternately continued, and a plurality of folded plate roof materials are superposed on the top portion 31a of the mountain portion 31 at the side edge. In addition, the overlapped portion 30a is connected by screwing the upward bolt 21 and the nut 22 together. Further, in order to prevent water from entering from the bolt hole 30b, a waterproof packing 24 is attached between the nut 22 and the top portion 31a, and a mountain covering the waterproof packing 24 between the nut 22 and the waterproof packing 24. A seat 23 is provided.

  Further, on the back side of the folded plate roof 30, a support metal fitting 33 for bolting is attached, which is substantially the same shape as the folded plate roof 30 in a front view. In addition, the attachment position of the upward bolt 21 for attaching the roof fixture 10 is not limited to the joint portion of the adjacent folded plate roofing material, and the upward bolt 21 may be attached to the other top portion 31a using the support fitting 33. .

  On the other hand, the on-roof fixture 10 is made of a metal plate or a hard resin plate, and is attached and fixed to the above-described upward bolt 21 for connecting the overlapping portion protruding upward from the top portion 31a of the folded plate roof 30. It has become.

  The on-roof fixture 10 is composed of two substantially gate-shaped sandwiching tools 10A and 10B having different dimensions in a nested state, and in this state, tightening bolts 16 are passed through both overlapping shaft holes 12a for tightening. The nut 17 is screwed and integrated.

  The large sandwiching tool 10A disposed on the outside and the small sandwiching tool 10B disposed on the inside have the same structure except for the sandwiching structure with respect to the upward bolt 21. In the drawings, the same reference numerals are given. In the following description, when the two sandwiching tools 10A and 10B are distinguished from each other, the large sandwiching tool 10A disposed on the outside is referred to as a sandwiching tool (large) 10A, and the small sandwiching tool 10B disposed on the inside. Is described as a sandwiching tool (small) 10B.

  Each of the two sandwiching tools 10A and 10B includes an upper plate 11, both leg pieces 12 extending downward from both ends thereof, and both sandwiching pieces which are bent and extended so as to face each lower end portion of both leg pieces 12. 13 and at least. Reinforcing ribs 11a and 12b are formed on the upper plate 11 and both leg pieces 12, respectively.

  The sandwiching tool (small) 10B is included in the sandwiching tool (large) 10A and is nested so that the upper plates 11 and the leg pieces 12 are closely polymerized. The tightening bolts 16 are passed through the overlapping shaft holes 12 a and screwed with the tightening nuts 17. In this state, the sandwiching pieces 13 and 13 of the two sandwiching tools 10A and 10B are arranged in two stages in the vertical direction via the gap space S1.

  The two sandwiching tools 10A and 10B are integrated by the tightening bolt 16 and the tightening nut 17. However, in order to bond them more firmly, the sandwiching tool (small) is used as in this embodiment. It is desirable to have a structure in which the reinforcing ribs 11a and 12b of 10B are fitted into the back side of the reinforcing ribs 11a and 12b of the sandwiching tool (large) 10A.

  The on-roof fixture 10 has two sandwiching tools 10A and 10B stacked in a nested state, and tightens the overlapping leg pieces 12 by screwing the tightening bolt 16 and the tightening nut 17 so that the upper and lower 2 The sandwiching pieces 13 arranged in a step are arranged to be close to each other in the lateral direction and sandwiched by the upward bolt 21.

  Moreover, in this embodiment, the clamping piece 13 extended from the leg piece 12 becomes a shape parallel to the surface of the top part 31a in 10 A of clamping tools (large) toward the front-end | tip 13b from the bending base 13a. On the other hand, the sandwiching tool (small) 10 </ b> B has an upright inclined shape so that it can be directly sandwiched with the shaft portion 21 a of the upward bolt 21.

  At the tip 13b (see FIG. 2) of each clamping piece 13 of these two types of clamping tools 10A and 10B, locking portions 14 and 15 having different structures that can be locked by the upward bolt 21 are formed. Has been. As shown in the enlarged plan view of FIG. 2 (c), the distal end portion of the sandwiching piece 13 of the sandwiching tool (large) 10A is configured as a locking portion 14, and a packing accommodating recess 14a is formed at the center thereof. Yes. Further, as shown in the enlarged plan view of FIG. 2B, the center of the distal end of the sandwiching piece 13 of the sandwiching tool (small) 10B is configured as a locking portion 15, and a locking recess 15c is formed at the center of the distal end. Two slits 15d are formed in the central portion of the slit, and the locking portion 15 is a locking protrusion 15a in which a plate piece sandwiched between the slits 15d is inclined upward and protruded. The shaft portion 21a of the upward bolt 21 can be locked with a total of three pieces including the inner edge pieces 15b that are not raised.

  The locking portions 14 of the pair of lower stages (the clamping tool (large) 10A) are inserted below the mountain seat 23 so as to face each other, and are hooked and locked to the mountain seat 23. The housing recess 14a forms a space when the tip of the lower locking portion 14 is inserted below the mountain seat 23 and close to each other, and the waterproof packing 24 (FIG. 1C) is cross-hatched in the space. The portion shown in FIG. 1 is accommodated (see FIGS. 1A and 1C).

  Thus, since the lower locking portion 14 has a structure that enters the lower side of the mountain seat 23, once the locking portion 14 is locked, it can be removed by pulling the roof mounting tool 10 from above or pressing it from the left and right. There is nothing.

  It should be noted that the tips of the lower locking portions 14 are preferably in contact with each other. However, a slight gap may be formed as long as the locking portions 14 are at least hooked to the mountain seat 23. Moreover, although the packing accommodating recessed part 14a prevents the contact with the waterproof packing 24, some contact is permitted as long as the waterproof packing 24 is not elastically contracted or damaged by pressing. The

  On the other hand, since the upper portion (the sandwiching tool (small) 10B) of the sandwiching piece 13 has a three-piece engagement portion 15 formed at the tip 13b, the upward bolt 21 is formed by the engagement portion 15. Each piece of the locking portion 15 consisting of a total of 6 pieces left and right toward the space formed by the two locking recesses 15c with respect to the outer peripheral surface of the shaft portion 21a of the shaft portion 21a into the screw groove on the outer peripheral surface of the shaft portion 21a Can be bitten and pinched.

  According to such a locking structure, the clamping force is strong by the two types of locking parts 15 and 14 formed in two upper and lower stages, and therefore, the clamping piece 13 clamped by the upward bolt 21 is caused by the external force. There is no risk of detachment from the upward bolt 21.

  Further, the clamping force of the upper locking portion 15 is combined with the clamping force of the lower locking portion 14 to obtain a strong clamping force. The upper locking portion 15 does not lock the inner edge piece 15b in the screw groove of the shaft portion 21a of the upward bolt 21, but only the locking protrusion 15a is locked in the screw groove of the shaft portion 21a. It is good also as a structure to do.

  Moreover, in order to give stronger clamping force, you may make it form the latching | locking part of 3 steps | paragraphs or more by combining 3 or more sets of clamping tools. In that case, only the locking portion 14 formed at the tip of the clamping piece 13 at the lowermost stage (the clamping tool (large)) is inserted between the top 31 a of the folded plate roof 30 and the mountain seat 23. The two or more upper locking portions are locked to the shaft portion 21 a of the upward bolt 21.

  The roof fixture 10 configured as described above is used by being attached to the folded plate roof 30 in the following manner.

  First, after passing through the shaft portion 16a of the tightening bolt 16 from one of the shaft holes 12a of the two sets of leg pieces 12 by the two sandwiching tools 10A and 10B of the roof mounting tool 10, the tip of the tightening bolt 16 is passed. The tightening nut 17 is lightly tightened from the side to temporarily fix the roof mounting fixture 10 from above the upward bolt 21 protruding from the folded plate roof 30 to the gap S2 between the left and right sandwiching pieces 13 in the figure. It mounts on the upper surface of the top part 31a of the folded-plate roof 30 so that the upward volt | bolt 21 may be inserted (refer Fig.4 (a)). When the on-roof fixture 10 is placed on the folded plate roof 30, the sandwiched piece 13 of the sandwiched tool (large) 10 </ b> A is in surface contact with the top portion 31 a of the folded plate roof 30.

  Next, when the tightening bolt 16 and the tightening nut 17 that have been temporarily fixed are tightened, the two pairs of leg pieces 12 by the two sandwiching tools 10A and 10B come close to each other by the tightening force, and the sandwiching piece 13 Are close to each other so that the gap S2 becomes small. Then, when the upper and lower sandwiching pieces 13 and 13 are close to each other, the engaging portion 14 formed at the distal end 13b of the sandwiching piece 13 of the sandwiching tool (large) 10A becomes the top 31a of the folded plate roof 30 and the mountain seat (See the enlarged plan view of the hill seat 23 surrounded by the broken line in FIG. 4B), and when closer, the tips of the sandwich pieces 13 come into contact with each other (FIG. 1C On the other hand, the locking recess 15c of the locking portion 15 formed at the tip of the clamping piece 13 of the clamping tool (small) 10B sandwiches the shaft portion 21a of the upward bolt 21 and the locking protrusion 15a. Then, the inner edge piece 15b bites into the thread groove of the shaft portion 21a of the upward bolt 21, and the rooftop fixture 10 is firmly connected and fixed to the folded plate roof 30 (FIGS. 4A and 4B). And FIG. 1).

  Various devices and members (not shown) can be attached above the upper plate 11 of the on-roof fixture 10 attached to the folded plate roof 30 in this way.

  As described above, according to the roof mounting fixture 10 of the present invention, the upward bolt 21 that protrudes from the folded plate roof 30 with two types of locking structures at the top and bottom by the two sandwiching tools 10A and 10B. Therefore, it is possible to reliably prevent the sandwiching piece 13 from being detached from the upward bolt 21 by an external force. In particular, since the lower locking portion 14 has a mounting structure that hooks and locks against the mountain seat 23, there is almost no possibility that the clamping piece 13 will come off, and the upper locking portion 15 is connected to the shaft portion of the upward bolt 21. Since it has a mounting structure that is clamped to 21a, it is possible to supplement clamping by the lower locking portion 14.

  Further, in the example shown in the figure, the clamping piece 13 of the upper stage (the clamping tool (small) 10B) is fixed in an inclined state, and the locking projection 15a of the locking part 15 is further inclined to the shaft part 21a. On the other hand, since it bites at an acute angle, there is almost no possibility that the roof mounting fixture 10 will come out of the upward bolt 21.

  FIG. 5 is a partial cross-sectional front view showing another construction example of the on-roof fixture 10 shown in FIG.

  Here, parts common to those in FIGS. 1 to 4 are denoted by the same reference numerals, overlapping description is omitted, and only different points will be described below.

  That is, in this construction example, the on-roof fixture 10 shown in FIG. 1 to FIG. 4 is used, and as a connection structure of the folded plate roof 30, a cross-section is substantially circular on the upper surface of the top portion 31 a of the folded plate roof 30. It is shown that they are connected by a round goby type goby part 25 protruding in a shape. The same applies to the square goby that protrudes in a substantially L-shaped cross section from the top 31a of the folded plate roof 30, and thus the explanation of the square goby and the like is omitted.

  Specifically, when the roof mounting fixture 10 of the present invention is attached to the goby portion 25, not the locking portions 14 and 15 but the two sandwiching tools 10 </ b> A and 10 </ b> B from the lower end of the leg piece 12. The end portion 13b of the sandwiching piece 13 projecting inwardly is attached to the leg portion 25a formed on the goby portion 25 of the folded plate roof 30.

  Therefore, the roof mounting fixture 10 has a structure having two upper and lower locking portions 15 and 14 to be clamped to the upward bolt 21, but the roof portion 25 formed on the top portion 31 a by the goby type joint is attached to the roof portion 25. It can be installed without any problems. Moreover, since the rib 13c is formed in the upper clamping piece 13, a contact area with the leg part 25a of the goby part 25 increases, and it can clamp more firmly.

  Each of the sandwiching pieces 13 of the two sandwiching tools 10A and 10B is placed on the top portion 31a as shown in this example so that the leg portion 25a of the goby portion 25 can be securely sandwiched between the left and right tips 13b. It is desirable to form them in parallel.
