Description

  The present invention relates to an on-roof mounting tool that is sandwiched between bolt bodies protruding from the top of a corrugated roof and is mounted on the 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 ridges in the corrugated roof where the ridges and valleys are alternately continuous, the overlapping parts formed by overlapping adjacent corrugated roof materials are connected by screwing bolts and nuts, In the case of a fixed structure, the roof mounting fixture has a structure in which the bolt body for connecting the roofing material, which protrudes on the roof through the overlapped portion from below the roof, is sandwiched and fixed by the opposing sandwich pieces. Has also been proposed.

  This on-roof fixture includes a main body portion having both leg pieces and a substantially inverted U-shaped cross section, and both inwardly facing flange pieces (both sandwich pieces) extending so as to face each other from the lower ends of the leg pieces. In addition, both leg pieces are fastened with fastening bolts and nuts penetrating the both leg pieces in the lateral direction, and both inwardly facing hook pieces are sandwiched and attached to the bolt body. According to such an attachment structure, since the tip end portion of the inward flange piece can be bitten into the screw groove of the bolt body and fixed, there is no possibility that the on-roof fixture is easily detached.

Japanese Patent No. 3368374

  However, in this type of structure, since the nut to be screwed to the bolt body is arranged on the upper surface of the corrugated roof, it is necessary to attach a roof mounting tool to a position above the nut. The roof mounting fixture cannot be attached in close contact with the roof, and may become unstable.

  The present invention has been proposed in view of such circumstances, and an object thereof is to provide an on-roof fixture that can be firmly and stably attached to a corrugated roof. Further, reducing the number of parts is also included in the object of the present invention.

  In order to achieve the above object, a roof mounting fixture according to a first aspect of the present invention includes a main body portion having both leg pieces and formed in a substantially inverted U-shaped cross section, and is folded so as to face each lower end of the both leg pieces. It has a structure that includes at least both inwardly extending flanges that are bent, and tightens both leg pieces so that both inwardly approaching pieces are close to each other and clamped to the bolt body protruding from the top of the corrugated roof. In the on-roof fixture, split female screw recesses that are opposed to each other and whose inner circumference is curved in an arc shape are formed at the tip portions of both inwardly facing flanges. The male screw part of the bolt body is sandwiched and meshed with each other.

  In the on-roof fixture according to claim 2, the split female screw recess is formed by cutting out the edge of the tip of the inward flange piece.

  The on-roof fixture according to claim 3 further includes an upright piece extending upward from the tip portion at the tip portion of the inward flange piece, and the divided female screw recess is formed in a groove shape in the vertical direction of the standup piece. Is formed.

  The present invention has the following effects.

  That is, according to the roof mounting tool according to claim 1, the divided female screw recesses that are opposed to each other and whose inner circumference is curved in an arc shape are formed at the respective front ends of both inwardly facing pieces, Since the split female screw recess sandwiches and engages with the male thread portion of the bolt body, the inward flange piece can be firmly sandwiched between the bolt body. In addition, since the inward flange piece has a female screw structure, a nut that is screwed to the bolt body is not required, and the number of parts can be reduced. Moreover, since a nut is unnecessary, an inwardly facing piece can be adhered to the upper surface of the corrugated roof, and the on-roof fixture can be stably and firmly attached to the corrugated roof.

  In the on-roof fixture according to claim 2, since the split female screw recess has a shape in which the edge of the tip portion of the inward flange piece is cut out, a female screw structure can be formed without requiring a special member. .

  In the on-roof fixture according to claim 3, the split female screw recess is formed in a concave groove shape in the vertical direction of the upright piece extending from the distal end portion of the inward flange piece. The entire length can be engaged, and the on-roof fixture can be firmly attached to the corrugated roof.

  The folded plate roof 30 used in the present embodiment is a roof in which mountain portions 31 and valley portions 32 are alternately arranged, and a plurality of folded plate roof materials are polymerized at the top portion 31a of the mountain portion 31, and the polymerization is performed. The part 30a has an overlapping structure in which the bolt body 21 and a split female screw recess of the roof mounting fixture 10, which will be described later, are connected by screwing. In order to prevent water from entering from the bolt hole 30b, it is desirable to attach a waterproof packing (not shown) around the bolt hole 30b on the top surface of the top portion 31a.

  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 bolt body 21 for connecting the overlapping portions protruding upward from the top portion 31a of the folded plate roof 30. It has become.

  Specifically, the on-roof fixture 10 includes a main body 11 having a substantially inverted U-shaped cross section including an upper plate 11a and both leg pieces 11b and 11b extending downward from both ends, and both leg pieces 11b and 11b. At least two inwardly extending flanges 12 and 12 that are bent and extended so as to face each other, tighten both leg pieces 11b and 11b, and make both inwardly extending flanges 12 and 12 close to each other. In this structure, the bolt body 21 is clamped to the male screw portion 21a. The leg pieces 11b, 11b are tightened by screwing a tightening bolt 13 and a tightening nut 14 that are passed through shaft holes 11ba, 11ba provided in the opposing leg pieces 11b, 11b.

  A split female screw recess 12ba that forms a female screw portion when both the tip portions 12b are clamped to the male screw portion 21a of the bolt body 21 is formed in each of the tip portions 12b of the inwardly facing flange pieces 12. Has been. The split female screw recess 12ba is located at a position facing each other, and has a shape in which the center of the edge of the tip end portion 12b is cut into an arc shape (semi-circular in the illustrated example), Is threaded. That is, when the distal end portions 12b of the inwardly facing flanges 12 are substantially in contact with each other, a circular virtual imaginary part separated into semicircles at the center of the continuous inwardly facing strips by the adjacent split female screw recesses 12ba. Through screw holes are formed.

  In addition, a sword tip bolt 15 is provided in the center of the upper plate 11a of the main body 11 so that various devices and members can be attached.

  When this on-roof fixture 10 is correctly attached to the folded-plate roof 30, as shown in FIG. 2, the male body of the bolt body 21 is inserted into a virtual through screw hole formed by joining two divided female screw recesses 12ba. A clamped state without a gap by the inwardly facing flange 12 is formed so that the screw portion 21a is inserted. At this time, the male screw portion 21a and the divided female screw recess 12ba are formed so that a screw groove and a screw thread mesh with each other to form a strong clamping relationship.

  In this example, a circular shape is formed by both split female screw recesses 12ba and can be engaged over the entire circumference of the male screw portion 21a of the bolt body 21, but a part of the periphery of the male screw portion 21a is shown. It may be capable of meshing. That is, each divided female screw recess 12ba may form a fan-shaped arc less than a semicircle.

  In addition, since the male screw portion 21a and the divided female screw recess 12ba are in a screwed relationship in this way, as described in detail in FIGS. It can fix to the folded-plate roof 30 reliably so that a clearance gap may not be made between the on-roof fixture 10 and the folded-plate roof 30. FIG.

  The roof fixture 10 configured as described above is used by being attached to the folded plate roof 30 in the following manner. In addition, although the bolt body 21 is projected in advance on the top portion 31a of the folded plate roof 30, since it is not fixed with a nut, the bolt body 21 is prevented from coming off during the mounting work of the on-roof fixture 10, It is desirable to use a clamping tool or the like (not shown) for temporarily fixing the bolt body 21.

  First, after passing the shaft portion 13a of the tightening bolt 13 from one of the shaft holes 11ba of the both leg pieces 11b, 11b of the roof mounting fixture 10, the tightening nut 14 is lightly tightened from the tip side of the tightening bolt 13. The folded plate roof 30 is set in a temporarily fixed state so that the bolt body 21 is inserted between the split female screw recesses 12ba from above the bolt body 21 protruding on the folded plate roof 30. (See FIGS. 3 (a) and 3 (b)).

  Next, when the tightening bolt 13 and the tightening nut 14 that have been temporarily fixed are tightened, both leg pieces 11b and 11b are brought close to each other by the tightening force, and the two split screw recesses 12ba approach each other, and the bolt body 21 And the split female screw recess 12ba and the male screw portion 21a mesh with each other to form a screwed relationship (FIGS. 3B and 4A). )reference).

  In this state, as shown in FIG. 3B and FIG. 4A, a slight gap S may be formed between the bottom surface of the inward facing piece 12 and the top surface of the top portion 31 a of the folded plate roof 30. However, since the roof mounting tool 30 and the bolt body 21 are in a screwed relationship, the roof mounting tool 10 can be brought into close contact with the top 31a by screwing and rotating (FIG. 4). (See (b)).

  Various devices / members D can be attached on the main body 11 of the on-roof fixture 10 thus attached to the folded roof 30 (see FIG. 4B).

  In this way, the on-roof fixture 10 is firmly attached to the folded plate roof 30 by the screwing / clamping relationship between the split female screw recess 12ba of the inward flange 12 and the male screw portion 21a of the bolt body 21. Can do. In addition, since the on-roof fixture 10 itself can be rotated and fixed, the attaching operation can be easily performed without using a tool.

  Moreover, since it is a structure which does not require the nut screwed together with the bolt body 21, the number of parts can be reduced. Furthermore, since a nut is not used, the inwardly facing piece 12 can be brought into close contact with the top surface of the top part 31a of the folded plate roof 30, and a sense of stability can be improved. Of course, the structure using a nut may be sufficient.

  Moreover, in this embodiment, since the bolt body 21 for attaching the roof mounting tool 10 to the folded plate roof 30 is also used for roof material connection, the number of parts for attachment may be reduced. it can.

  FIG. 5 is an exploded perspective view showing an attachment state of the on-roof fixture 10 shown in the first embodiment to another type of folded-plate roof. In addition, since the on-roof fixture 10 shown in this example is the same as that of the first embodiment, the description of the detailed structure is omitted.

  The corrugated roof to which the on-roof fixture 10 is attached in the illustrated example is a goby-type folded plate roof 30 in which the roof materials are connected by the gouge portion 35. That is, the goby portion 35 has a structure in which both roof materials are joined at the tip via a roof material polymerization base portion 35a formed by superposing and projecting from the top portion 31a. Note that the present invention can be similarly applied to a square goby or the like that protrudes in a substantially L-shaped cross section on the upper surface of the goby-type folded plate roof 30.

  The construction procedure for the folded plate roof 30 of the on-roof fixture 10 is substantially the same as the construction procedure shown in FIGS. In other words, the tightening nut 14 is lightly tightened from the front end side of the tightening bolt 13, temporarily fixed to the gouge portion 35 of the folded plate roof, and further tightened, so that the inward flange 12 is the roof material polymerization base portion of the gouge portion 35. 35a can be sandwiched.

  As described above, in the case of the goby-type folded plate roof 30 as shown in the figure, the split female screw recess 12ba of the on-roof fixture 10 is not used, but both inwardly facing flange pieces 12 are tightened by tightening both leg pieces 11b. Therefore, the structure can be easily applied to the goby type folded plate roof 30. Further, the split female screw recess 12ba has a shape in which the edge of the distal end portion 12b of the inwardly facing piece 12 is cut out, so that it does not interfere with the pinching to the gob portion 35.

  Next, the second embodiment will be described.

  FIG. 6 is an exploded perspective view showing a second embodiment of the on-roof fixture according to the present invention. FIG. 7 is a perspective view showing a state in which the on-roof fixture is attached to the corrugated roof. Moreover, FIG. 8 (a), (b) and FIG. 9 (a), (b) are sectional drawings which show the construction state of a mounting tool on a roof.

  In addition, description is abbreviate | omitted about the structure of the superposition type folded-plate roof 30 common to FIGS. 1-4 shown in 1st Embodiment.

  The on-roof fixture 10 is made of a metal plate or a hard resin plate, and has a structure in which it is attached and fixed by being sandwiched by the above-described bolt body 21 for connecting the overlapping portions protruding upward from the top portion 31a of the folded plate roof 30. ing.

  Specifically, the on-roof fixture 10 includes a main body 11 having a substantially inverted U-shaped cross section including an upper plate 11a and both leg pieces 11b and 11b extending downward from both ends, and both leg pieces 11b and 11b. At least two inwardly extending flanges 12 and 12 that are bent and extended so as to face each other, tighten both leg pieces 11b and 11b, and make both inwardly extending flanges 12 and 12 close to each other. In this structure, the bolt body 21 is clamped to the male screw portion 21a. The leg pieces 11b, 11b are tightened by screwing a tightening bolt 13 and a tightening nut 14 that are passed through shaft holes 11ba, 11ba provided in the opposing leg pieces 11b, 11b.

  In the present embodiment, upright pieces 12c extending upward from the edges of the front end portions 12b are formed at the front end portions 12b of the both inwardly facing flange pieces 12, respectively. Prior to tightening, these standing pieces 12c stand substantially in parallel through a predetermined gap, and in the center of each of them, a split female screw recess (hereinafter referred to as a split groove) having a groove shape along the vertical direction. Female thread concave groove 12ca).

  The split female screw groove 12ca is formed by curving the inner periphery in a semicircular shape on both opposing surfaces of both standing pieces 12c, and a screw groove is formed on the inner peripheral surface to form a female screw portion. Moreover, the protruding item | line formed by the division | segmentation internal thread recessed groove 12ca is seen by the back surface side of the standing piece 12c.

  When the on-roof fixture 10 is correctly attached to the folded plate roof 30, the two divided female screw grooves 12ca are sandwiched between the male screw portions 21a of the bolt body 21 without a gap as shown in FIG. At this time, the male screw portion 21a and the divided female screw groove 12ca are engaged with each other so that a strong clamping relationship is formed. In particular, since the divided female screw groove 12ca is formed over the entire height of the upright piece 12c, the upright piece 12c of the inward flange piece 12 can be clamped over substantially the entire length of the male screw portion 21a of the bolt body 21. Also in this embodiment, the divided female screw groove 12ca may be able to mesh with a part of the periphery of the male screw portion 21a.

  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 13a of the tightening bolt 13 from one of the shaft holes 11ba of the both leg pieces 11b, 11b of the roof mounting fixture 10, the tightening nut 14 is lightly tightened from the distal end side of the tightening bolt 13. The bolt body 21 is fitted into the space formed between the split female screw grooves 12ca of the standing piece 12c from the upper side of the bolt body 21 protruding in the folded plate roof 30 in the temporarily fixed state. As it is inserted, it is placed on the top surface of the top portion 31a of the folded plate roof 30 (see FIGS. 8A and 8B).

  Next, when the tightening bolt 13 and the tightening nut 14 that have been temporarily fixed are tightened, both the leg pieces 11b and 11b are brought close to each other by the tightening force, and the two split screw grooves 12ca approach each other. The screw portion 21a is sandwiched so as to surround the periphery thereof, and the divided female screw groove 12ca and the male screw portion 21a are engaged with each other to form a screwed relationship (see FIGS. 8B and 9A). ).

  In this state, as shown in FIGS. 8B and 9A, a slight gap S may be formed between the bottom surface of the inward facing piece 12 and the top surface of the top portion 31 a of the folded plate roof 30. However, since the roof mounting fixture 10 and the bolt body 21 are screwed together, the roof mounting fixture 10 can be brought into close contact with the top portion 31a by screwing and rotating (FIG. 9). (See (b)).

  Various devices / members D can be attached on the main body 11 of the rooftop fixture 10 attached to the folded plate roof 30 (see FIG. 9B).

  Thus, since there exists a screwing and pinching relationship between the division | segmentation internal thread groove | channel 12ca formed in the standing piece 12c of the inward flange piece 12, and the external thread part 21a of the bolt body 21, 1st Embodiment Similarly to the on-roof fixture 10 shown in FIG. 1, the on-roof fixture 10 can be firmly and stably attached to the folded-plate roof 30. Further, since the on-roof fixture 10 itself can be screwed and fixed, the construction can be easily performed without using a tool. Moreover, since the division | segmentation internal thread recess becomes the concave groove shape which can clamp the external thread part 21a of the bolt body 21 in a longer range, both are connected strongly.

  In the first and second embodiments described above, the example in which the roof mounting fixture 10 is arranged in the overlapping portion 30a of both adjacent roof materials is shown, but the roof is formed on the top of the mountain portion where the overlapping portion 30a is not formed. The upper fixture 10 may be attached.

  Moreover, although the above 1st, 2nd embodiment showed the example which has arrange | positioned the roof fixture 10 so that both leg pieces 11b and 11b may be arranged along the direction of the peak part 31 and the trough part 32. The on-roof fixture 10 may be arranged so that both leg pieces 11b and 11b are arranged along the wave direction.

  In addition, although it is desirable to arrange | position the roof mounting fixture 10 in the said 2 types of direction, you may distribute | arrange in any direction other than those.

  Further, the above-described roof mounting tool can be attached to a flat plate (not having a corrugated shape) roof.
