Description

  The present invention relates to an on-roof fixture that can be fixed to a superposed portion formed by superposing side edge portions of corrugated roof materials adjacent to 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 peaks and troughs are alternately continuous, the overlapping portions formed by overlapping adjacent corrugated roof materials are connected by screwing bolts and nuts. In a fixed structure, a roof having a structure in which a bolt body for connecting a folded plate roof material, which protrudes on the roof through the overlapping portion from below the roof, is sandwiched and fixed between opposing sandwich pieces. An upper fixture 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 hook pieces (both sandwich pieces) extending so as to face each other from the lower ends of both leg pieces. The structure has a structure in which both leg pieces are fastened with tightening bolts and nuts penetrating both leg pieces in the lateral direction, and both hook pieces are attached to the bolt body. According to such an attachment structure, since the tip end portion of the flange piece can bite into the screw groove of the bolt body and can be fixed, there is no possibility that the on-roof attachment device 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 on-roof fixture cannot be attached in a state of being in close contact with the roof, and may become unstable.

  The present invention has been proposed in view of such circumstances, and the object thereof is to provide a nut that is attached to a corrugated roof in a stable state and the roof mounting fixture itself fixes the overlapping portion of the corrugated roof. An object of the present invention is to provide an on-roof fixture having a female screw function instead of the above.

  In addition, in order to give the roof mounting fixture a female screw function, it can be assumed that a screw hole corresponding to the bolt body is provided, but there are various sizes of bolt bodies for fixing the overlapping portion of the corrugated roof. Therefore, it is necessary to manufacture multiple types of on-roof fixtures of the same shape with different female thread dimensions depending on the dimensions of the bolt body. In this case, the number of production increases, production facilities increase, and inventory management. Is expected to be complicated.

  In consideration of such assumptions, nuts are not required, the number of roof fixtures produced is not increased, production facilities are not increased, and inventory management is complicated. It is also an object of the present invention to provide a highly convenient rooftop fixture.

  In order to achieve the above object, an on-roof fixture according to claim 1 includes an upper plate, leg pieces, and a superposed portion formed by superposing side edges of corrugated roof materials adjacent to the corrugated roof. An on-roof fixture provided with a hook piece to be attached is characterized in that a screw hole to be screwed into a bolt body penetrating from below the overlapping portion of the corrugated roof is formed in the hook piece.

  The rooftop fixture according to claim 2 includes at least a main body portion having an upper plate and both leg pieces and formed in a substantially inverted U-shaped cross section, and both hook pieces extending in a lateral direction from respective lower end portions of both leg pieces. In the on-roof fixture having a structure that can be fixed to the overlapping portion formed by overlapping the side edge portions of the corrugated roof material adjacent to the corrugated roof, The first screw hole is formed so that the hook piece can be fixed to the corrugated roof by being screwed into the bolt body penetrating from below the overlapping portion of the corrugated roof, and the overlapping portion of the corrugated roof is formed on the other hook piece. The second screw hole is formed so that the bolt piece can be fixed to the corrugated roof by screwing into a bolt body penetrating from below.

  In the on-roof fixture according to claim 3, the first screw hole and the second screw hole have different hole diameters.

  The present invention has the following effects.

  That is, according to the roof mounting tool according to claim 1 or 2, since the screw hole to be screwed into the bolt body penetrating from below the overlapping portion of the corrugated roof is formed in the flange piece, The tool itself replaces the nut that is screwed onto the bolt body used to secure the overlapping portion of the corrugated roof. Therefore, since it is not necessary to use a nut, the on-roof fixture can be stably attached to the corrugated roof. Further, since the on-roof fixture can be attached and fixed to the corrugated roof by screwing with a screw hole, it is not necessary to include a member or structure for attachment, and thus the structure can be simplified.

  Further, according to the roof mounting tool of the second aspect, the first screw hole is formed in one of the two flange pieces, and the second screw hole is formed in the other, so that the screw body can be screwed into the screw body. Therefore, if the on-roof fixture is cut so as to separate the two roof pieces, it can be used as an on-roof fixture for two corrugated roofs with one product. That is, since it is sufficient to produce two on-roof fixtures as one item, the number of production can be reduced.

  According to the on-roof fixture according to the third aspect, the first screw hole and the second screw hole have different hole diameters. Any one of the screw holes and the second screw holes may be used, and the screw holes can be used separately, which is very convenient. Moreover, since it is only necessary to produce two types of fixtures as one type of product, it is possible to prevent an increase in production facilities and complication of inventory management.

It is a disassembled perspective view which shows 1st Embodiment of the roof mounting tool which concerns on this invention. (A) is a front view of the roof mounting tool shown in FIG. 1, and (b) is a side view of the same. It is a front view which shows the other usage example of the same fixture on a roof. (A), (b) is a front view which shows two other examples of 1st Embodiment, respectively. (A)-(c) is a front view of three examples of the on-roof fixture which respectively shows 2nd Embodiment of the on-roof fixture concerning this invention.

  Embodiments of the present invention will be described below 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 (substantially semicircular peaks and valleys) It can also be applied to roofs that are alternately continuous. Moreover, as materials for the roof, metals, synthetic resins, cement-based materials and the like can be applied.

  FIG. 1 is an exploded perspective view showing a first embodiment of a rooftop fixture according to the present invention. 2 (a) is a front view of the on-roof fixture shown in FIG. 1, and FIG. 2 (b) is a side view thereof. FIG. 3 is a front view showing another example of use 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 continuous, and the side edge of the adjacent folded plate roof material is the top portion 31a of the mountain portion 31. The superposed portion 30a is superposed and connected to the bolt body 21 by screwing the bolt body 21 with a first screw hole or a second screw hole described later. 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 roof mounting fixture 10 includes an upper plate 11a for installing various devices and members (not shown), and both leg pieces 11b and 11b extending downward from both ends of the upper plate 11a. A main body portion 11 having a substantially inverted U-shaped cross section and both flange pieces 12 and 12 which are bent and extended so as to face each lower end of both leg pieces 11b and 11b are provided.

  Then, the first screw hole 121a having a large diameter is opened in one of the two pieces 12, 12 (the right piece in FIG. 2A, hereinafter referred to as the first piece 121). A second screw hole 122a having a small diameter is formed in the other hook piece (the left hook piece in FIG. 2A, hereinafter referred to as the second hook piece 122).

  These first and second screw holes 121a and 122a are both screw holes for screwing into the bolt body 21 for connecting the overlapping portion 30a of the folded plate roof 30, and the diameter of the bolt body 21 is the same. In addition, either one of the screw holes can be used. In the illustrated example, the first screw hole 121a is screwed into the connecting bolt body 21 of the overlapping portion 30a.

  Thus, the first screw hole 121a of the first flange 121 is screwed into the male screw portion 21a of the bolt body 21, so that the roof mounting fixture 10 is fixedly mounted on the upper side of the top portion 31a (overlapping portion 30a).

  Thus, since the roof fixture 10 is structured to be attached to the folded plate roof 30 by screwing the screw hole and the bolt body 21, the roof fixture 10 itself can be rotated without using a tool. Can be mounted on the roof while. Moreover, since the 1st collar piece 121 which has the 1st screw hole 121a becomes a substitute of the nut with respect to the volt | bolt body 21 for fixation of the superposition | polymerization part 30a, naturally, it is not necessary to use a nut, Therefore, on the roof The fixture 10 can be stably attached to the folded roof 30 and the number of parts can be reduced. Further, since the on-roof fixture 10 can be attached and fixed to the folded plate roof 30 by screwing with screw holes, it is not necessary to include a member or structure for attachment, so that the structure can be simplified and the number of parts can be reduced accordingly. Can be reduced.

  FIG. 3 is a front view showing another example of use of the on-roof fixture 10.

  In this example, the folded plate roof material of the folded plate roof 30 is formed thinner than the roof material of FIG. 1, and the bolt body 21 that connects the overlapping portions 30a has a smaller diameter accordingly. Therefore, the roof mounting tool 10 is attached by screwing the second screw hole 122 a having a small diameter formed in the second flange 122 into the bolt body 21.

  Thus, since the roof mounting tool 10 has the first screw hole 121a and the second screw hole 122a having different hole diameters, the bolt body 21 having a large diameter shown in FIGS. It can be used for the folded plate roof 30 as well as the folded plate roof 30 using the small-diameter bolt body 21 shown in FIG.

  In addition, the roof mounting fixture 10 is cut at the position A shown in FIG. 3 by cutting the upper plate 11a, and the first roof mounting fixture 101 having the first screw holes 121a and the second screw holes 122a. If it divides | segments into the 2nd on-roof fixture 102 which has, it can use separately with respect to 2 types of folded-plate roof 30 (bolt body 21).

  Since the on-roof fixture 10 has a structure including fixtures for the two types of folded-plate roof 10 as described above, the diameter dimension of the bolt body 21 used for fixing the overlapping portion 30a of the folded-plate roof 30 is as follows. Any one of the first screw hole 121a and the second screw hole 122a may be used according to the above, and the convenience is extremely high. Moreover, since the roof mounting fixture 10 has a structure in which the first roof mounting fixture 101 and the second roof mounting fixture 102 are integrated (made into one product), the number of products produced can be reduced. In particular, since two types of products having different screw hole diameters are included, it is possible to prevent an increase in production facilities and complication of inventory management by integrating them.

  1 to 3, the first screw hole 121a and the second screw hole 122a are shown on the roof mounting fixture 10 having different diameters. However, the first screw hole 121a and the second screw hole are illustrated. 122a may be a roof mounting tool having the same diameter. Even in this case, since the two pieces are integrated, it is possible to expect an effect that the number of production does not increase.

  FIGS. 4A and 4B are front views of the on-roof fixture according to the other two examples of the first embodiment.

  Each of these on-roof fixtures 10 has a structure that can be fixed to a superposed portion 30a formed by superposing side edge portions of adjacent folded plate roof materials of the folded plate roof 30. Similar to the rooftop fixture 10 shown in FIG. 1, the main body 11 composed of the upper plate 11a and both leg pieces 11b, 11b has a substantially inverted U-shaped cross section, and one of the collar pieces 12 (first collar piece 121). A first screw hole 121a is formed, and a second screw hole 122a having a hole diameter different from that of the first screw hole 121a is formed in the other collar piece 12 (first collar piece 122). Although it is comprised so that the body 21 may be screwed together, the whole shape differs from the on-roof fixture 10 shown in FIG.

  That is, the roof mounting fixture 10 of FIG. 4A has the same shape as the roof mounting fixture 10 shown in FIG. 1 in the main body 11 composed of the upper plate 11a and both leg pieces 11b, 11b. The tip of the piece 121 is directed outward, and the tips of both flange pieces 12, 12 are formed so as to face in the same direction.

  4B, the positions of the leg pieces 11b and 11b and the collar piece 12 are the same as those in FIG. 4A, but the upper plate 11a extends to the right, and the right first The shape covers the upper part of the flange 121. Therefore, since the upper plate 11a covers the upper side of the first and second collar pieces 121 and 122, the first screw hole 121a and the second screw hole 122a are separated from the on-roof mounting tool 10. Thus, it can cut | disconnect in B position and can utilize by isolate | separating into the 1st rooftop fixture 101 and the 2nd rooftop fixture 102. FIG.

  In addition, as a shape of a roof mounting tool, the main-body part may be formed so that a cross section may be a substantially inverted U-shaped cross section, and both hook pieces may face the outside.

  Next, a second embodiment of the on-roof fixture according to the present invention will be described.

  Fig.5 (a)-(c) is a front view of the on-roof fixture which shows 2nd Embodiment, respectively.

  These on-roof fixtures 10A are also structured to be fixed by being attached to the overlapping portion 30a of the folded plate roof 30, and an upper plate 11a for installing various devices and members (not shown), and leg pieces 11b. And one flange piece 12 attached to the overlapping portion 30a, and the screw piece 12 is formed with one screw hole 12a screwed into the bolt body 21 penetrating from below the overlapping portion 30a. . 5 (a) and 5 (b) has one leg piece 11b and the overall shape is a U-shape and a Z-shape, respectively, while the one in FIG. There are two pieces 11b, and the overall shape is a square shape. The shape of the on-roof fixture 10A in FIG. 5A corresponds to the first on-roof fixture 101 or the second roof fixture 102 shown in FIG.

  Thus, these roof mounting fixtures 10A are also formed with the screw holes 12a screwed to the bolt bodies 21 in the collar piece 12, so that the roof mounting fixture 10 of the first embodiment (FIG. 1). Similarly to the reference), the on-roof fixture 10A can be attached to the folded plate roof without using a nut.

  In the above two examples of the first embodiment and the example of the second embodiment, the on-roof fixture 10 is arranged so that both leg pieces 11b and 11b are arranged along the direction of the peak portion 31 and the valley portion 32. However, the on-roof fixture 10 may be arranged so that both leg pieces 11b and 11b are arranged along the wave direction, or may be arranged in any other direction.
