Description

  The present invention relates to an on-roof fixture fixed to a bolt body protruding from the top of a corrugated roof.

  In general, on the top surface of a corrugated roof such as a folded plate roof (angular corrugated roof) or a round corrugated roof, for example, an article on the roof made of various devices and members such as a TV antenna, an air conditioner, a solar panel, and a heat shield sheet is arranged. In the past, various on-roof fixtures for mounting such an on-roof article on the roof have been proposed.

  In particular, in the structure in which the overlapped part where the adjacent roof materials are stacked at the top of the corrugated roof is fixed by screwing bolts and nuts, the top penetrates the roof from below the roof and protrudes onto the roof. An on-roof fixture having a configuration in which a bolt body for connecting a provided roof material is sandwiched and fixed by opposing sandwich pieces has also been proposed (see, for example, Patent Document 1).

  This on-roof fixture includes a main body portion having both leg pieces and a substantially gate-shaped cross section, and both sandwiching pieces extending so as to face each other from the lower ends of the both leg pieces. The bolts are tightened with nuts and nuts that penetrate through the two bolts, and both clamped pieces are clamped and attached to the bolt body. According to such an attachment structure, since the leading end portions of the both sandwich pieces bite into the thread grooves of the screw portions of the bolt body, the possibility that the on-roof fixture is removed is low.

JP 2010-77692 A

  However, in the above conventional roof mounting tool, both leg pieces must be tightened with tightening bolts and nuts, which increases the amount of work on the roof, and can only be quickly installed by a skilled person. It was.

  Further, depending on the tightening, tightening to the bolt body may not be sufficient, and there is a possibility that it may be displaced or disengaged depending on the load of the article on the roof. In addition, since the fixing is performed by tightening, there is a possibility that the fixing degree varies between the on-roof fixtures.

  In particular, when the thermal insulation sheet is fixed to a plurality of roof mounting fixtures via rails, for example, when snow is deposited on the thermal insulation sheet, the roof is arranged on both sides of the thermal insulation sheet due to the weight of snow. The fixture was pulled in the center, and there was a risk that the roof fixture with the lowest fixed strength would rise while tilting.

  The present invention has been proposed in view of such circumstances, and its purpose is a roof that can be easily and quickly attached with a fixed strength to a bolt body protruding from the top of a corrugated roof. It is to provide an upper fixture.

  In order to achieve the above object, the on-roof fixture according to claim 1 is an on-roof fixture fixed to a bolt body protruding from the top of the corrugated roof. The mounting recess is fitted with a roof mounting portion that is mounted on the corrugated roof at the bottom, and the roof mounting portion comprises a bolt insertion hole provided with an expanding claw piece on the inner periphery. A bolt locking part is provided, and the expansion claw piece is configured to be locked to a bolt body protruding from the bolt insertion hole.

  In the on-roof fixture according to claim 2, the fixture main body is formed of a groove shape.

  In the roof mounting tool according to the third aspect, the bolt locking portion is formed integrally with the mounting tool main body.

  In the on-roof fixture according to claim 4, the bolt locking portion is formed separately from the fixture main body.

  According to the roof mounting tool according to claim 1, the roof mounting portion of the mounting tool main body includes a bolt locking portion including a bolt insertion hole provided with an expanding claw piece on the inner periphery, and the expanding Since it is configured to lock to the bolt body protruding from the bolt insertion hole with the claw piece, the fixture body can be attached simply by locking the bolt body protruding from the top of the corrugated roof, and the mounting work Can be done easily and quickly.

  In addition, since the expanding claw piece can correspond to bolt bodies of various diameters, one type of on-roof fixture can be used corresponding to various bolt bodies having different diameters. In addition, it is not necessary to prepare many kinds of fixture bodies. As a result, the number of product types can be reduced, and inventory management can be simplified. Furthermore, since the mounting structure is such that the bolt body is simply inserted into the bolt insertion hole, the fixing strength between the on-roof mounting tools can be made uniform without variation.

  Furthermore, since the on-roof fixture according to claim 1 is provided with a mounting recess for fitting an article on the roof, a rail for attaching the article on the roof is attached together with a plurality of on-roof fixtures, and a heat shielding sheet is attached. It is possible to install items on the roof, etc., but since the fixing strength between the roof fixtures can be made uniform by the bolt locking part, even when cooperating with multiple roof fixtures like that The fixed state can be maintained in a well-balanced manner without any of the on-roof fixtures being displaced or detached from the bolt body.

  According to the on-roof fixture of claim 2, since the fixture main body is formed of a groove shape, the on-roof fixture can be configured compactly with a small amount of material, and the groove shape allows a space above the roof mounting portion. Since it is made, it is easy to visually check the mounting state and easy to check. In particular, when the bolt locking portion is a separate body, the mounting operation can be performed easily.

  According to the on-roof fixture according to claim 3, since the bolt locking portion is formed integrally with the fixture main body, the fixture main body can be attached only by inserting the bolt body into the bolt insertion hole. . In addition, the number of parts constituting the roof fixture can be reduced, and the work on the roof can be performed very easily. Furthermore, since the number of parts is small, it is easy to handle on site and inventory management can be simplified.

  According to the roof mounting tool of the fourth aspect, since the bolt locking portion is formed separately from the mounting tool main body, a large bolt is inserted into the roof mounting portion of the mounting tool main body (free insertion). ) Open a hole. Therefore, even if one type of bolt locking part (expansion claw piece) cannot cope with various bolt bodies and various bolt locking parts are required, the bolt insertion holes of the roof mounting part have the same size. Since the same kind of fixture body (part excluding the bolt locking portion) can be used, the convenience is high. Moreover, even if the shape and size of the bolt body is not known unless it is on-site, it is only necessary to bring one type of fixture body and a plurality of types of bolt locking portions to the site, so there will be no burden on transportation.

It is a schematic perspective view which shows the usage example of the on-roof fixture of this invention.

  Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings. In the following, as the corrugated roof to which the on-roof fixture of the present invention is attached, an angular corrugated roof, that is, a folded-plate roof, is exemplified, but a round corrugated roof (a substantially semicircular mountain and trough are It can also be applied to alternating roofs). Moreover, as materials for the roof, metals, synthetic resins, cement-based materials and the like can be applied.

  Drawing 1 is an explanatory view showing an example of a 1st embodiment of a roof fixture concerning the present invention, and is an exploded perspective view showing a state before attachment to a corrugated roof of a roof fixture. FIG. 2 is a perspective view showing a state after the mounting tool on the roof is attached to the corrugated roof. 3 (a) and 3 (b) are partial cross-sectional front views showing a construction procedure for the on-roof fixture.

  The folded plate roof Y used in this example 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 on the side edge. The superposed top Y1a has a stacked structure in which the bolt body B and the nut C for connection are connected by screwing.

  For example, as shown in the figure, the bolt body B is integrated with a support fitting Y3 having substantially the same shape as the folded plate roof Y in a front view, and has a sword-tip tip protruding upward. By pushing the folded plate roof Y from above the bolt body B, the top Y1a is penetrated by the sword tip of the bolt body B, and the folded plate roof Y is attached.

  Moreover, the bolt body B which penetrated the top part Y1a of the folded-plate roof Y is fixed by screwing the nut C which integrated the mountain washer D. In order to prevent water from entering from a hole (not shown) in the folded plate roof Y through which the bolt body B has penetrated, a waterproof packing E is attached below the washer D.

  The on-roof fixture 10 passes through the top Y1a of the folded plate roof Y in this way, and is attached to the bolt body B secured with the nut C.

  This on-roof fixture 10 (attachment fixture body 10A) has a roof mounting portion 12 at the bottom, and includes a pair of upright pieces 11 that are bent and extended upward from both ends of the roof mounting portion 12. A groove shape is formed as a whole, and an attachment recess 13 cut out in the same shape is formed at each upper end portion of the upright pieces 11.

  In this attachment recess 13, as shown in the embodiment example of FIG. 9, when a plurality of on-roof fixtures 10 are attached side by side, a long rail R for attaching an article on the roof is fixed. The upper end opening of the mounting recess 13 is preferably smaller than the bottom of the recess so that the rail R does not come off. It is desirable to form a slip-off preventing piece 14 for preventing the rail R from coming off.

  Note that the mounting recess 13 is not limited to this, and may be formed by recessing or hollowing the center of the upper plate of the cylindrical body.

  In addition, a raised bottom portion 12a is formed in the central portion of the roof mounting portion 12 so as not to conflict with the nut C or the mountain washer D when the fixture main body 10A is installed on the top portion Y1a of the folded plate roof Y. At the center of the raised bottom portion 12a, a bolt locking portion 20 for locking to the bolt body B, which is formed by a bolt insertion hole 21 provided with an expanding claw piece 22 on the inner periphery, is formed.

  In this example, as shown in FIG. 1, four expansion claw pieces 22 of the bolt locking portion 20 are formed, and they protrude slightly upward toward the center of the bolt insertion hole 21. A small hole 21 a surrounded by the tip of the piece 22 is formed.

  As shown in FIGS. 3A and 3B, when the fitting body 10A is fitted from above so that the bolt body B protruding from the folded plate roof Y is inserted into the small hole 21a, it expands. When the claw piece 22 hits the outer peripheral surface of the shaft portion B1 of the bolt body B, the claw piece 22 is elastically deformed upward and the small hole 21a is expanded. In this state, the fixture body 10A rubs the shaft portion B1 of the bolt body B. The lower surface of the roof mounting portion 12 reaches the upper surface of the top portion Y1a of the folded plate roof Y. Then, the fixture main body 10A is fixed to the folded plate roof Y in a state where the expanding claw piece 22 and the thread groove of the shaft portion B1 of the bolt body B are engaged with each other. Thus, since the expansion claw piece 22 of the bolt locking portion 20 bites into the thread groove of the shaft portion B1 of the bolt body B, the fixture body 10A does not come off from the bolt body B.

  Thus, on-roof fixtures 10 (not shown) such as rails and heat shield sheets can be attached on the rooftop fixture 10 attached to the folded plate roof Y.

  Thus, the fixture body 10 </ b> A includes the bolt locking portion 20 including the bolt insertion hole 21 provided with the expansion claw piece 22 on the inner periphery, and the bolt protruding from the bolt insertion hole 21 with the expansion claw piece 22. Since it has an attachment structure that is locked to the body B, the on-roof fixture 10 can be attached simply by fitting the bolt body B projecting from the top Y1a of the folded plate roof Y into the bolt insertion hole 21, Installation work can be performed easily and quickly.

  Moreover, according to the expansion nail | claw piece 22 of the bolt latching | locking part 20, since it can be made to respond | correspond to the bolt body B of various diameters, one type of on-roof mounting tool 10 respond | corresponds to various bolt bodies B from which a diameter differs. Therefore, it is not necessary to prepare many kinds of fixture main bodies according to the shape and size of the bolt body B. That is, it is possible to deal with many sites with a small number of types of on-roof fixtures 10. Further, since the mounting structure is such that the bolt body B is simply inserted into the bolt insertion hole 21, the fixing strength between the roof mounting tools 10 can be made uniform without variation.

  Moreover, since the bolt locking part 20 is integrally formed with the fixture main body 10A, the roof fixture 10 of this example can reduce the number of parts of the roof fixture 10 and work on the roof extremely. It can be done easily. Moreover, since the number of parts is small, inventory management can be simplified.

  Furthermore, since the on-roof fixture 10 of this embodiment is provided with the mounting recess 13, the rail R (see FIG. 9) is attached together with the plurality of on-roof fixtures 10, and an on-roof article such as a heat shield sheet is installed. However, since the fixing strength can be made uniform among the on-roof fixtures 10 by the bolt locking portions 20, any roof can be used even when cooperating with the plural on-roof fixtures 10. The upper fixture 10 can be maintained in a well-balanced state as a whole without being displaced or detached from the bolt body B.

  Moreover, since the on-roof fixture 10 of this embodiment has a groove shape, it is easy to visually check the attached state and easy to check, and work efficiency can be improved.

  Next, two other examples of the bolt locking portion in the present embodiment will be described with reference to FIG. 4A is a plan view of another example of the bolt locking portion, and FIG. 4B is a perspective view of still another example.

  The bolt locking portion 20 of FIG. 4A is provided with three pieces of expanding claw pieces 22 on the inner periphery of the bolt insertion hole 21. Thus, even if the number of the expanding claw pieces 22 is three, since the structure is fixed so as to sandwich the shaft portion B1 of the bolt body B, the locking is not released. Moreover, you may provide so that the two pieces of expansion claw pieces 22 may be opposed.

  Further, the bolt locking portion 20 of FIG. 4B is formed with two upwardly extending claw pieces 22 slightly upward so as to face each other on the two short sides facing each other of the rectangular bolt insertion hole 21. . Also by this bolt locking part 20, since it can be firmly locked to the bolt body B by the expanding claw piece 22, the same effect as the on-roof mounting tool 10 shown in FIG.

  Next, a second embodiment of the present invention will be described. In the second embodiment, the folded plate roof Y, the bolt body B, the nut C, and the like are the same as those in the first embodiment, and thus the same reference numerals are given and description thereof is omitted.

  FIG. 5 is an explanatory view showing an example of the second embodiment of the on-roof fixture according to the present invention, and is an exploded perspective view showing a state before the on-roof fixture is attached to the corrugated roof. FIG. 6 is a perspective view showing a state after the mounting tool on the roof is attached to the corrugated roof. 7 (a) and 7 (b) are partial cross-sectional front views showing a construction procedure for the on-roof fixture.

  The on-roof fixture 10 shown in the present embodiment has a separate bolt locking portion (hereinafter referred to as a bolt locking body 20A).

  10 A of fixture main bodies have the roof mounting part 12 in the bottom part, are equipped with a pair of standing piece 11 bent upwards from the both ends of the roof mounting part 12, and become a groove shape as a whole. A mounting recess 13 cut out in the same shape is formed at the upper end of each of the upright pieces 11.

  In the mounting recess 13, as in the roof mounting tool 10 of FIG. 1, when a plurality of roof mounting tools 10 are mounted side by side, a long rail R (see FIG. 9) or the like can be fixed. And a slip-off preventing piece 14 that prevents the rail R and the like from being removed.

  A raised bottom portion 12a is formed at the center of the roof mounting portion 12 so as not to conflict with the nut C and the mountain washer D when the fixture body 10A is installed on the top Y1a of the folded plate roof Y. A bolt loose insertion hole 12aa for loosely inserting the bolt body B is formed in the center of the bottom portion 12a. In addition, although the bolt insertion hole which can be inserted without clearance may be sufficient, in order to improve workability | operativity, it is more desirable to use the bolt loose insertion hole 12aa.

  Further, the bolt locking body 20A is made of a disk made of metal or hard resin, and a bolt insertion hole 21 provided with an expanding claw piece 22 on the inner periphery is formed at the center thereof.

  In this example, as shown in FIG. 5, the four expanding claw pieces 22 of the bolt locking body 20 </ b> A are formed, and they protrude slightly upward toward the center of the bolt insertion hole 21. A small hole 21 a surrounded by the tip of the piece 22 is formed.

  As shown in FIGS. 7A and 7B, the fixture body 10A is inserted into the bolt loose insertion hole 12aa of the roof mounting portion 12 so that the bolt body B protruding from the folded plate roof Y is inserted into the folded plate roof. After mounting on the top Y1a of Y, when the bolt locking body 20A is fitted into the bolt body B protruding upward from the upper surface of the roof mounting section 12, the expanding claw piece 22 is By hitting the outer peripheral surface of the shaft portion B1, the roof mounting portion 12 is deformed elastically upward and the small hole 21a is expanded. In this state, the fixture body 10A scrubs the shaft portion B1 of the bolt body B. Reach the inner bottom of. Then, the fixture main body 10A is fixed to the folded plate roof Y in a state where the expanding claw piece 22 and the thread groove of the shaft portion B1 of the bolt body B are locked. Since the expanding claw piece 22 bites into the thread groove of the shaft portion B1 of the bolt body B in an obliquely upward state, the fixture body 10A does not come off from the bolt body B.

  Thus, on-roof fixtures 10 (not shown) such as rails and heat shield sheets can be attached on the rooftop fixture 10 attached to the folded plate roof Y.

  As described above, the roof mounting tool 10 includes the bolt engaging body 20A including the bolt insertion hole 21 provided with the expansion claw piece 22 on the inner periphery, and the bolt claw insertion hole 12aa, the bolt Since it becomes the structure latched to the bolt body B which protruded from the insertion hole 21, the mounting tool 10 on a roof is only put by inserting the bolt insertion hole 21 in the bolt body B protruding from the top part Y1a of the folded-plate roof Y. It can be installed and the installation work can be done easily and quickly. Further, the fixture body 10A can be securely and firmly attached to any bolt body B at various sites, and the fixing degree between the on-roof fixtures 10 can be made uniform without variation.

  Moreover, since the bolt locking body 20A is formed separately from the fixture main body 10A, the roof mounting tool 10 of this example has a large bolt loose insertion hole in the roof mounting portion 12 of the fixture main body 10A. Just open 12aa. Furthermore, it is not necessary to store a plurality of types of fixture main bodies 10A according to the shape and size of the bolt body B. Therefore, inventory management can be simplified. Even if the shape and size of the bolt body B is not known unless it is on-site, transportation is not a burden because it is only necessary to bring one type of fixture body 10A and a plurality of types of bolt locking bodies 20A to the site.

  Further, when a roof article such as a rail R (see FIG. 9) is attached to the attachment recess 13 by cooperation of the plurality of roof attachment tools 10, the overall balance is good as in the first embodiment. A fixed state can be maintained. Moreover, since the on-roof fixture 10 has a groove shape, it is easy to visually check the mounting state and easily inspect, and it is easy to mount the bolt locking body 20A.
