Description

  The present invention relates to an on-roof fixture that is clamped and fixed to a protruding body such as a bolt body or a goby portion protruding on a roof.

  Generally, on-roof mounting articles such as TV antennas, air conditioners, solar battery panels, heat shield sheets, etc. are mounted on the top surface of corrugated roofs such as folded plate roofs (square corrugated roofs) and round corrugated roofs. It is practiced to attach and fix through a long frame.

  Conventionally, for example, as a roof mounting tool for mounting a roof mounting article on a roof, there is a structure having a clamping tool that is clamped and fixed to a bolt member for connecting a roof material protruding on the roof. The thing is proposed (refer patent document 1).

  Specifically, this on-roof fixture is fastened with tightening bolts and nuts penetrating laterally through both leg pieces of the sandwiching tool formed in a substantially portal shape so as to face each lower end of both leg pieces. It has the structure which clamps both the clamping pieces extended to the bolt body.

  In addition, in the rooftop fixture described in Patent Document 1, the groove-shaped long frame is fixed to the pedestal portions of a plurality of sandwiching tools with screws at the bottom of the groove.

JP 2011-174333 A

  However, in the construction of the long frame by the above conventional roof mounting tool, the screw hole is opened at the bottom of the long frame and screwed to the clamping tool at the site, so it is shaving powder when the screw hole is opened Metal chips may scatter and remain in the grooves of the long frame and remain. If left as it is, the chips may rust due to rain water, etc., and the rust may reach the surrounding roof surface. .

  In particular, there has been a demand for an attachment structure in which chips scattered in the groove are difficult to remove and the chips are not generated or can be easily removed even if they are generated.

  In addition, it is possible to assume that a bolt insertion hole is opened in advance in the base part of the sandwiching tool and the bottom part of the long frame and bolted in the field, but the interval between the sandwiching tool is not constant or errors It may be difficult to specify the position of the bolting in advance. In addition, since it takes time to screw the bolts and nuts when bolting, efficient construction cannot be expected.

  Furthermore, in the conventional one, the long frame is fixed and supported by a plurality of roof mounts, but the plurality of roof mount clamps are arranged in the longitudinal direction of the long frame. When it is not arranged linearly along the long frame, the long frame cannot be attached straight, and it is necessary to reattach the clamping tool.

  The present invention has been proposed in view of such circumstances, and the purpose thereof is to allow a long frame to be fastened and fixed simply, quickly and reliably to a clamping tool without using screws, and the long frame. An object of the present invention is to provide an on-roof fixture capable of adjusting the fixing position so that the frame can be fixed straight.

The fixed position is adjustable.

  The on-roof fixture according to claim 2 is configured such that at least one of the pair of holding pieces can slide with respect to the main body portion by a shaft fixing mechanism including a slide long hole and a shaft hole. .

  The on-roof fixture according to claim 3 is configured such that at least one of the pair of sandwiching pieces sandwiches the end portion in the width direction of the long frame between the main body portion.

  According to the roof mounting tool of claim 1, the long frame is sandwiched and fixed from both sides in the width direction by the pair of clamping pieces of the frame mounting tool. It can be fastened and fixed easily, quickly and reliably. In addition, since there is no need for screwing, chips of course cannot be generated by screwing, and there is no risk of rusting by chips.

  Further, since the fixing position of the long frame in the width direction is adjustable in at least one of the pair of holding pieces, a plurality of on-roof attachment tools for fixing and supporting the long frame Even when the frame is not arranged linearly along the longitudinal direction of the long frame, the long frame can be fixed only by adjusting the holding pieces of the frame fixture. Further, since the holding piece can be adjusted, the interval of the holding gap can be adjusted in accordance with the width dimension of the long frame. That is, it is possible to deal with long frames having various width dimensions with one type of roof mounting tool.

  According to the roof mounting tool of claim 2, at least one clamping piece of the pair of clamping pieces is configured to be slidable with respect to the main body by a shaft fixing mechanism including a slide long hole and a shaft hole. Therefore, the frame fixture can be formed with a simple configuration, and the configuration can be adjusted at low cost.

  According to the on-roof fixture according to claim 3, since at least one of the pair of sandwiching pieces is configured to sandwich the end in the width direction of the long frame between the main body part, It is possible to more firmly fix the groove-shaped long frame whose both side walls are inclined inward. Moreover, since it is the structure which can pinch | interpose and fix a side wall with a clamping piece and a main-body part, it can prevent the upper frame from coming off.

  The folded plate roof Y is a roof in which the mountain portions Y1 and the valley portions Y2 are alternately continuous, and a plurality of folded plate roof materials are polymerized at the top portion Y1a of the mountain portion Y1 of the side edge, and the bolts are formed at the superimposed portion. It has a lap-type joining structure in which the body B (projecting body) and the nut C1 are screwed together.

  The nut C1 is integrally formed with a washer C2 (a mountain washer in the illustrated example) below the nut C1. The washer C2 includes a waterproof packing C3 for preventing water from entering downward from the bolt holes of the roofing material.

  Further, on the back side of the folded plate roof Y, a support fitting Y3 for bolting, which is substantially the same shape as the folded plate roof Y in a front view, is attached. In addition, the attachment position of the bolt body B for attaching the roof mounting fixture A is not limited to the overlapping portion of the adjacent folded plate roof material, and the bolt body B may be attached to the other top portion Y1a using the support fitting Y3. .

  This on-roof mounting tool A is a frame mounting on which a substantially gate-shaped clamping tool 10 structured to be clamped to a projecting body such as a bolt body B and a long frame 1 for installing a roof mounting article can be fixed. The tool 20 is provided.

  In the present embodiment, a groove-shaped frame is used as the long frame 1. This long frame 1 has a shape in which the width dimension of the groove opening 1a is smaller than the width dimension of the bottom portion 1b, and both side walls 1c are inclined inward.

  The clamping tool 10 is made of a metal plate or a hard resin plate, and has a structure that is clamped on a bolt body B protruding upward from the top Y1a of the folded plate roof Y, and is fixed on the roof.

  More specifically, the body of the sandwiching tool 10 includes a base part 11 having a frame mounting tool 20 disposed above and a fixing hole 11b for fixing the shaft, and a pair of leg pieces extending downward from both ends thereof. 12 and 12 and sandwiched pieces 13 and 13 that are bent and extended from the lower ends of the leg pieces 12 and 12 so that the tips are opposed to each other, are formed by a substantially gate-shaped body. .

  The sandwiching tool 10 tightens both leg pieces 12 and 12 by screwing a tightening bolt 15 and a tightening nut 16 that are passed through shaft holes 12a and 12a provided in the opposing leg pieces 12 and 12. Thus, the ends of both the sandwiching pieces 13 and 13 are brought close to each other so as to be sandwiched by the bolt body B.

  In the illustrated example, a reinforcing rib 11a is formed on the pedestal 11, and reinforcing ribs 12b and 12b are formed on both leg pieces 12 and 12, respectively.

  The clamping piece 13 is inclined upward in the opposite direction, and a locking recess 13a for locking the shaft portion B1 of the bolt body B is formed at the center of the tip, and both locking recesses 13a are formed. The bolt body B is clamped. A locking piece 13b for locking the bolt body B is cut and raised at the center of the locking recess 13a. Further, reinforcing ribs 13c are formed on both sides of the locking recess 13a at the tip.

  On the other hand, the frame fixture 20 includes a body portion 21 in which a plurality of members constituting the frame fixture 20 are made of a metal or a hard resin plate and placed and fixed on the pedestal portion 11 of the sandwiching tool 10. It has a configuration provided with a pair of sandwiching pieces 22, 22 disposed on the upper side and sandwiching and fixing the long frame 1 from both sides in the width direction.

The main body portion 21 is formed of a bent plate having a recessed central portion, and a fixing portion 21a protruding downward at the central portion is placed on the pedestal portion 11, and the fixing hole 21ab of the fixing portion 21a and the pedestal portion 11 are fixed. The rivet R can be inserted into the hole 11b to be caulked. Further, on both sides of the fixed portion 21a, a sandwiching piece mounting portion 21b in which a slide long hole 21ba is formed along the longitudinal direction of the main body portion 21 is formed to extend. In addition, the dimension of the recess depth of the fixing part 21a may be a dimension so that the head of the rivet R does not protrude from the upper surface of the sandwiching piece mounting part 21b when riveted. 21 includes a fixed plate portion 22a having a shaft plate 22ab, and a pinching protrusion 22b protruding in an inclined manner from the inner edge of the fixed plate portion 22a.

  Each of the sandwiching pieces 22 and 22 is disposed on both the sandwiching piece mounting portions 21 b and 21 b of the main body portion 21, and is fixed by bolts 23 and nuts 24. And the elongate frame 1 is attached and fixed to the gap | interval (frame fitting part 25) between both the fixed clamping pieces 22 and 22. As shown in FIG.

  In this way, the long frame 1 is fixed to the roof mounting fixture A, and as shown in FIG. 8, another portion of the long frame 1 is further fixed to the other roof mounting fixture A, so that a plurality of roofs are attached. It is supported by the upper fixtures A and A.

  The on-roof fixture A composed of the sandwiching tool 10 and the frame fixture 20 is fixed to the top Y1a of the folded plate roof Y by the following procedure.

  First, the shaft portions 15a of the tightening bolts 15 are passed through the shaft holes 12a and 12a of the both leg pieces 12 and 12 of the sandwiching tool 10, and then the both leg pieces 12 are tightened by the tightening nuts 16 on the distal end side of the tightening bolts 15. , 12 are lightly tightened into a temporarily fixed state, and the clamping body 10 in this state is inserted into the bolt body B from above the bolt body B protruding from the top Y1a through the gap between the leg pieces 12, 12. , Put on the top Y1a (see FIG. 3).

  Next, when the tightening bolt 15 and the tightening nut 16 that have been temporarily fixed are tightened, both the leg pieces 12 and 12 are brought close to each other by the tightening force, and at the same time, both the sandwiching pieces 13 and 13 are also brought close to each other. Both locking recesses 13a, 13a of both clamping pieces 13, 13 clamp the shaft portion B1 of the bolt body B, and the side and bottom portions (locking pieces 13b) of the locking recess 13a are the bolt body B. The sandwiching tool 10 is fixed to the folded plate roof Y by biting into the screw grooves.

  In addition, when attaching the sandwiching tool 10 to the roof, as shown in FIGS. 3 and 4, the frame mounting tool 20 may be fixed to the pedestal portion 11 so that the subsequent adjustment is easy. In addition, the main body 21 and the sandwiching pieces 22 and 22 may be connected to a degree of temporary fixing (a state where the bolt 23 and the nut 24 are loosened). Of course, the frame fixture 20 may be attached to the pedestal portion 11 after fixing the sandwiching tool 10 to the folded plate roof Y.

  Next, the procedure and structure for attaching the long frame 1 to the frame fixture 20 will be described with reference to FIGS.

  First, both the sandwiching pieces 22 and 22 of the frame mounting tool 20 are slid outward along the slide long hole 21ba of the main body portion 21, and the gap between the sandwiching projections 22b and 22b (frame fitting portion 25) is long. Spread the shank frame 1 so that it can be attached. Then, the long frame 1 is inserted into the frame fitting portion 25 from above (see FIG. 5).

  Next, the holding pieces 22 and 22 are slid to the center along the long slide holes 21ba and 21ba so that the holding protrusions 22b and 22b firmly press the side wall of the long frame 1. In this state, the holding pieces 22 and 22 are fixed with respect to the main-body part 21 with the volt | bolt 23 and the nut 24 (refer FIG. 6).

  Thus, the long frame 1 is fixed to the frame fixture 20 fixed to the rooftop fixture.

  As shown in FIG. 7, the long frame 1 is fitted to a plurality of rooftop fixtures A, A fixed to a plurality of top portions Y1a, Y1a, and is supported by a plurality of rooftop fixtures A, A over the entire length. Fixed.

  As described above, the on-roof fixture A has a structure in which the long frame 1 is fitted and fixed to the frame fitting portion 25 of the frame fixture 20 with the clamping pieces 22 and 22 interposed therebetween. The scale frame 1 can be fastened and fixed simply, quickly and reliably to the clamping tool 10 without using screws. In addition, since there is no need for screwing, chips of course cannot be generated by screwing, and there is no risk of rusting by chips.

  Further, since the frame fitting portion 25 is open at the top, the long frame 1 can be attached to the frame fitting portion 25 from above, so that a long frame that is difficult to handle can be inserted. It can be attached regardless of the slide from the width direction, and the attaching operation can be performed easily and quickly. Moreover, if the holding pieces 22 and 22 are slid to both sides and the gap between the frame fitting portions 25 is sufficiently widened, it is not necessary to apply force enough to press-fit when mounting from above, and labor is required for work. It does not take.

  Furthermore, since the frame mounting tool 20 of the present embodiment is formed in an inclined shape so that the sandwiching protrusion 22b matches the inclined surface of the side wall of the long frame 1, the end of the long frame 1 in the width direction Can be sandwiched and fixed between the sandwiching protrusions 22b, 22b and the main body 21, and the long frame 1 can be prevented from coming off upward.

  A plurality of long frames 1 attached and fixed in this manner are attached so as to be substantially parallel to each other. That is, as shown in FIG. 8, a plurality of on-roof fixtures A, A, A are arranged along the direction of formation of the top Y1a of the folded-plate roof Y, whereby a plurality of long frames 1, 1, 1, are arranged. And the heat shield sheet 3 is stretched so as to straddle between the plurality of long frames 1, 1, 1 attached thereto.

  The heat shield sheet 3 is fixed in the groove of each long frame 1, and the frame cover 2 is attached thereon.

  Although the illustration of the attachment structure of the heat shield sheet 3 to the long frame 1 is omitted, for example, a structure in which the heat shield sheet 3 is pressed and fixed to the inner bottom surface by another member in the groove may be used. The heat shield sheet 3 may be fixed by fitting the frame cover 2 to the groove opening 1a of the frame 1, and various fixing structures may be used.

  As described above, the on-roof fixture A has a structure in which the long frame 1 is sandwiched and fixed by the main body portion 21 and the pair of sandwiching pieces 22 and 22 attached to the upper portion thereof, and thus is formed in a groove shape. The long frame 1 can be fixed in a state where the groove opening 1a protrudes upward and is opened upward. Therefore, when attaching the heat shield sheet 3 using the groove space, the heat shield sheet 3 can be easily fixed to the long frame 1 and the frame cover 2 can be easily attached, and the construction can be performed simply, quickly and reliably. Can do.

  Moreover, since the on-roof fixture A has a structure in which the long frame 1 is attached to the frame fixture 20 that is separate from the clamp 10, the conventionally used clamp 10 can be used as it is. .

  In addition, in this embodiment, although the heat-shielding sheet 3 was shown as an example of the on-roof attachment article attached via the long frame 1 on the plurality of on-roof attachments A, the case where other on-roof attachment articles are attached It can also be applied to.

  Further, since the holding position of the long frame 1 in the width direction of the long frame 1 is adjustable, the holding piece 22 can be adjusted even if the long frame 1 is not arranged directly above the holding tool 10 due to an error or the like. By adjusting the fixing position of the sandwiching piece 22, that is, the position where the frame fitting portion 25 is formed, the long frame 1 can be reliably fixed. This advantage will be described together with other examples shown in FIGS.

  FIG. 9 is an exploded perspective view showing another installation mode of the on-roof fixture A shown in FIG. FIG. 10 is a schematic plan view showing an installation mode example when a plurality of on-roof fixtures A are installed on the roof shown in FIG. 9, and FIG. 10 (a) is a diagram showing the attachment positions of the sandwiching tools. FIG. 10B is a view showing a state in which the long frame 1 is attached.

  As shown in FIG. 9, this installation mode is different from the example of FIG. That is, the folded plate roof Y is obtained by connecting two folded plate roof materials at the top portion Y1a by the gob joint method, and the sandwiching tool 10 is attached to the gouge portion H.

  In addition, since it is the same as that of the example of FIG. 1 about each structure of the clamping tool 10 and the frame fixture 20 which comprise the roof mounting fixture A, description about those parts is abbreviate | omitted.

  Thus, when attaching the pinching tool 10 to the goby part H, since the goby part H is formed along the formation direction of the top part Y1a, the freedom degree of the attachment position of the pinching tool 10 is high. As shown to Fig.10 (a), the some clamping tool 10,10,10 attached may not be arranged linearly.

  However, since the clamping piece 22 of the frame fixture 20 can be slidably adjusted in the direction in which the gouge portion H is formed with respect to the main body portion 21, the clamping fixture 10 is attached as shown in FIG. Even when the positions are deviated from each other, as shown in FIG. 10B, the frame fitting portions 25 can be arranged in a straight line by shifting the fixing position of the holding pieces 22.

  Since the central sandwiching tool 10 in FIG. 10 is attached slightly lower in the figure than the left sandwiching tool 10, by sliding the both sandwiching pieces 22 and 22 slightly upward in the figure. The formation position of the frame fitting part 25 can be adjusted, and the right sandwiching tool 10 is attached slightly above the left sandwiching tool 10 in the figure, so that both sandwiching pieces 22 and 22 are slightly below the figure. The formation position of the frame fitting portion 25 can be adjusted by sliding adjustment to the side.

  Since the frame fitting portions 25 are linearly arranged by the slide adjustment of the sandwiching pieces 22 and 22, the long frame 1 can be fixed to the individual on-roof fixtures A and A without difficulty.

  Moreover, since the slide adjustment of the clamping piece 22 is possible, the space | interval of the frame fitting part 25 (clamping gap) can be adjusted corresponding to the width dimension of the elongate frame 1. FIG. That is, one type of on-roof fixture A can correspond to the long frame 1 having various width dimensions.

  Next, an on-roof fixture according to another embodiment of the present invention will be described with reference to FIG.

  This on-roof fixture A differs from the one shown in FIG. 1 in the shape and structure of the frame fixture 20. Since the sandwiching tool 10, the long frame 1 and the roof are the same as those in FIG. 1, the same reference numerals as those in FIG.

  The frame fixture 20 includes a main body portion 21 and a pair of sandwiching pieces 22, 22. One sandwiching piece 22 (a sandwiching protrusion 22 b) is formed integrally with the main body portion 21, and the other sandwiching piece. 22 is formed as a separate body and can be fixed to the main body 21 with a bolt 23 and a nut 24. This separate holding piece 22 can be slid by a shaft fixing mechanism formed by a slide long hole 21ba and a shaft hole 22ab provided in the holding piece mounting portion 21b of the main body portion 21 as in the case of FIG. ing.

  This is effective when fixing the long frame 1 of various width dimensions because only the position of one clamping piece 22 is variable regardless of the mounting position of the clamping tool 10.

  In the embodiment described above, the shaft fixing mechanism in which the main body portion 21 is provided with the slide long hole 21ba and the pinching piece 22 is provided with the shaft hole 22ab is exemplified, but the main body portion 21 is provided with the shaft hole and the pinching piece 22 is provided with the slide long hole. The provided structure may be sufficient. Further, the adjusting mechanism of the sandwiching piece 22 is not limited to the mechanism using the shaft fixing mechanism including the slide long hole and the shaft hole, and may be another adjusting mechanism.

  In the two types of embodiments described above, the frame attachment tool 20 has the same relative attachment position with respect to the sandwiching tool 10, but the frame attachment tool 20 is in various positions with respect to the sandwiching tool 10. It may be attached. For example, the frame fixture 20 may be fixed so that the longitudinal direction of the frame fixture 20 is aligned with the arrangement direction of the leg pieces 12, 12 of the sandwiching tool 10.
