Description

  The present invention relates to an on-roof fixture 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, a structure in which the overlapping portions of adjacent roof materials are connected and fixed by screwing bolts and nuts at the tops of the peak portions of the corrugated roof in which the peak portions and the valley portions are alternately continuous. In the case, the shaft part of the bolt body for connecting the roofing material, which protrudes from the roof through the overlapping part from below the roof, is sandwiched and fixed by sandwiching pieces whose ends are opposed to each other. On-roof fixtures have also been proposed.

  This on-roof fixture extends from the lower ends of both leg pieces by tightening both leg pieces with fastening bolts and nuts that penetrate the leg pieces of the sandwiching tool formed in a substantially portal shape in the lateral direction. The both sandwiched pieces are sandwiched between bolt bodies. Therefore, since the front end of the sandwiching piece is fixed in a state of being bitten into the thread groove of the bolt body, there is no possibility that the on-roof fixture is easily detached.

  Moreover, although the thing of patent document 1 is comprised from a pair of clamping member with which the clamping tool was fulcrum-coupled, this kind of thing is applied to the structure which clamps both clamping pieces to a bolt body. In the same manner, there is no possibility that the on-roof fixture is easily detached.

Japanese Patent No. 3368374

  However, in the case of the on-roof mounting tool that is mounted by being clamped to the bolt body, there are the following problems.

  15A and 15B are schematic explanatory views showing two examples of attachment examples of a conventional roof mounting fixture to be attached to a corrugated roof, and FIG. 15A is a side edge of the corrugated roof Y. FIG. FIG. 15 (b) shows an example of clamping to a bolt body B in a lap joint structure. FIG. 15 (b) shows an example of sandwiching a goby part C formed by gore type joining at the top part Y1a of the crosspiece Y1. . 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 possibility that the sandwiching piece 101 sandwiched between the part C and the bolt body B will slide up.

  In this case, although there is a possibility that a slight shift may occur in the case attached to the goby portion C, since the upper portion of the gouge portion C protrudes in the lateral direction, there is no possibility that the roof mounting tool 100 comes out of the gouge portion C. (See FIG. 15A.) In the case where the bolt is mounted on the bolt body B, the roof mounting tool 100 is gradually tilted by a strong tensile force, and the tip of the sandwiching piece 101 connects the shaft portion B1 of the bolt body B. There is a possibility that it may come off while sliding up (see FIG. 15B).

  Therefore, the roof mounting tool 100 of the type that is mounted by being clamped to such a bolt body B needs to have a structure that is mounted with a stronger clamping force than that to be mounted on the seam portion C. .

  The present invention has been proposed in view of such circumstances, and its purpose is to attach it to a bolt body projecting on the upper surface of the corrugated roof with a strong clamping force in the case of the corrugated roof having a lap joint structure. Another object of the present invention is to provide an on-roof mounting tool that does not have a possibility that a clamping piece clamped to a bolt body is detached from the bolt body by an external force.

  In order to achieve the above-mentioned object, the roof mounting tool according to claim 1 is provided with a substantially portal-shaped sandwiching tool provided with a pair of sandwiching pieces facing each other at the lower end, and the sandwiching tool. In a roof mounting fixture with a structure in which a pair of sandwiching pieces are brought close to each other and sandwiched between bolt bodies protruding from the top of a corrugated roof, the tip of the sandwiching piece is locked to the outer peripheral surface of the bolt body The possible locking piece is formed in a plurality of stages in the vertical direction.

  In the on-roof fixture according to claim 2, the plurality of locking pieces are formed by separating and arranging the sandwiching pieces in the vertical direction.

  In the on-roof fixture according to claim 3, the plurality of steps of the locking pieces are formed by bending and raising.

  In the on-roof fixture according to claim 4, the sandwiching tool is integrally formed including a leg piece formed by bending the sandwiching piece at the lower end and an upper plate having the leg pieces at both ends, and a pair of legs. A pair of clamping pieces are brought close to each other by tightening the pieces.

  In the on-roof fixture according to the fifth aspect, the sandwiching tool is configured by connecting a pair of sandwiching members in which sandwiching pieces are bent at the lower ends thereof so that they can be opened and closed.

  In the on-roof fixture according to claim 6, the clamping member has a bolt through hole formed in the center, an upper plate in which a cut groove extending from the bolt through hole to one side edge is formed, and a base end of the upper plate It consists of a leg piece that extends further downward and a sandwich piece that extends from the lower end of the leg piece in substantially the same direction as the upper plate, and the sandwiching tool has the upper plates of the two sandwich members facing each other. In this state, the upper plate's slits are inserted into each other so that the top ends of the top plates are positioned below the base end of the mating top plate. The holes are made to coincide with each other, the clamping tool fastening bolts are passed through the matched bolt through holes, and the fastening nuts are screwed together so that the tips of the clamping pieces are brought close to each other.

  The present invention has the following effects.

  According to the roof mounting tool of the first aspect, since the locking pieces that can be locked to the outer peripheral surface of the bolt body are formed in a plurality of stages in the vertical direction at the tip of the clamping piece of the clamping tool, The clamping force becomes strong by the plurality of locking pieces, and therefore, there is no possibility that the clamping piece clamped to the bolt body is detached from the bolt body by an external force.

  According to the on-roof fixture according to claim 2, since the plurality of locking pieces are formed by separating and arranging the sandwiching pieces in the vertical direction, for example, a leg that is a base end portion of the sandwiching piece If a part of the original sandwiched piece is cut and raised from an appropriate position of the piece and arranged side by side, a plurality of locking pieces can be manufactured at low cost without increasing the material.

  According to the on-roof fixture according to the third aspect, since the plurality of locking pieces are formed by bending and cutting up, molding can be easily performed.

  According to the on-roof fixture according to claim 4, the sandwiching tool is integrally formed including the leg piece formed by bending the sandwich piece at the lower end and the upper plate having the leg piece at both ends. For this reason, the sandwiching tool can be constructed in a sturdy and simple shape. Moreover, since it is integrally formed, there is little possibility that a deviation will occur between both sandwiched pieces. Further, since the pair of leg pieces are tightened to bring the pair of sandwich pieces close to each other, a tightening structure can be realized simply by providing a tightening bolt or the like for tightening the pair of leg pieces. Can be simple. In addition, the top plate may project a sword bolt for mounting various devices / members, etc., but it may be configured not to have a sword tip bolt or the like. The top can be used for various aspects.

  According to the roof mounting tool according to claim 5, the sandwiching tool is configured by connecting a pair of sandwiching members in which the sandwiching pieces are bent at the respective lower ends so as to be openable and closable, By operating the force point, the pinching piece that is the action point can be operated, and as a result, the pinching piece can be pinched to the bolt body by a simple operation.

  According to the on-roof fixture according to claim 6, the sandwiching tool is in a state in which the top plates of the two sandwiching members are opposed to each other, and the leading ends of the mutual top plates are the base ends of the mating top plate. As shown below, the upper plate's cut grooves are inserted into each other, the upper plates are oscillatingly meshed so that the bolt through-holes are aligned with each other, and the clamping bolts are tightened in the aligned bolt through-holes. Since the tip of the clamping piece is brought close to each other by passing the attached bolt and screwing the clamping nut, the upper plate that overlaps the two is tightened in the vertical direction with the clamping tool clamping bolt and the clamping nut The clamping piece can be easily brought close to and clamped to the bolt body. In particular, if the tightening nut is arranged on the upper surface side of the upper plate, the tightening operation can be further easily performed.

  Further, since the sandwiching tool is composed of two sandwiching members and they are connected to each other so as to be openable and closable, when the sandwiching tool tightening bolt and the tightening nut are loose, The wearing member is also in a loose state. Therefore, in order to fix the clamping piece in the closed state, it is only necessary to fix the upper plates by tightening the loosened nuts, and such tightening can be performed manually, so that the workability is good.

FIG. 3A is a partial cross-sectional front view showing the state, FIG. 3A is a partial cross-sectional front view showing the state where the roof mounting fixture A is attached to the bolt body of the folded plate roof, and FIG. The partial cross-sectional front view which shows the state which further attached various apparatuses and members D to the tool A is shown, respectively.

  The details will be described below.

  Examples of the corrugated roof to which the on-roof fixture A is attached include the folded plate roof Y (angular corrugated roof) and the round corrugated roof shown as examples. Moreover, as materials for the roof, metals, synthetic resins, cement-based materials and the like can be applied.

  The folded plate roof Y shown as an example is a roof in which mountain portions Y1 and 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, It has a lap-type joining structure in which the bolt body B and the nut B2 are connected by screwing at the overlapping portion. Further, in order to prevent water from entering from the bolt hole, a waterproof packing (not shown) is attached between the nut B2 and the top Y1a. Furthermore, you may provide the mountain seat which covers packing between nut B2 and packing.

  The on-roof fixture A is made of a metal plate or a hard resin plate, and is attached to and fixed by the above-mentioned bolt body B for connecting the overlapping portion protruding upward from the top Y1a of the folded roof Y. It has become.

  Specifically, the roof mounting fixture A is formed by bending the top plate 11, a pair of leg pieces 12 extending downward from both ends thereof, and the lower ends of the leg pieces 12 so that the tips are opposed to each other. The bolt body B is formed of a substantially gate-shaped sandwiching tool 1 integrally formed with the sandwiched piece 13 and tightens both leg pieces 12 so that the ends of the sandwiched pieces 13 are close to each other. It is structured to be sandwiched between the shaft portions B1. The tightening of the leg pieces 12 is performed by screwing the tightening bolts 25 penetrating through the shaft holes 12 a provided in the opposing leg pieces 12 and the tightening nuts 26. In addition, a sword tip bolt 3 or the like similar to the bolt body B is erected in the center of the upper plate 11 so that various devices and members D (see FIG. 3B) can be attached.

  Locking pieces 15 that can be locked to the outer peripheral surface of the shaft portion B1 of the bolt body B are formed in two steps in the vertical direction at the tip of the sandwiching piece 13. Specifically, the front end of the sandwiching piece 13 is formed in two steps by folding the plate piece, and the locking piece 15 having the same shape is formed at each of the two ends.

  As shown in the developed plan view of FIG. 1B, the locking piece 15 is formed by partially cutting, bending, and raising a plate piece, and can be easily molded. is there. In addition, the broken line in FIG.1 (b) has shown the return part.

  Further, as shown in the enlarged plan view of the periphery of the locking piece 15 surrounded by a broken line in FIG. 1A, a recess 14 is formed at the center of the tip of the sandwiching piece 13, and two strips are formed in the central portion. A notch groove 14a is formed, and the locking piece 15 includes both a locking protrusion 15a obtained by projecting a plate piece sandwiched by the notch groove 14a upward and protruding, and a recess 14 that is not raised. It consists of a total of three pieces with the inner edge piece 15b.

  That is, since the engagement piece 15 made of such three pieces is formed in the upper and lower stages at the tip of the sandwiching piece 13, the both sandwiching pieces 13 form the outer peripheral surface of the shaft portion B1 of the bolt body B. On the other hand, the locking piece 15 consisting of 12 pieces of upper and lower gauges can be bitten into the screw groove of the shaft portion B1 of the bolt body B and can be sandwiched.

  According to such a locking structure, the clamping force is increased by the locking pieces 15 formed in two upper and lower stages, and therefore, the clamping piece 13 clamped to the bolt body B is detached from the bolt body B by an external force. There is no fear of it.

  Note that the locking piece may have a structure in which the inner edge piece 15b is not locked in the thread groove of the bolt body B, and only the locking protrusion 15a is locked in the thread groove and sandwiched. Even in this case, since the upper and lower locking projections 15a made of four pieces are formed at the tips of the both sandwiching pieces 13, a strong sandwiching force can be obtained.

  Further, in order to give a stronger clamping force, three or more steps of locking pieces may be formed at the tip of the clamping piece 13 by bending or cutting.

  The on-roof fixture A of the present invention configured as described above is used by being attached to the folded plate roof Y in the following manner.

  First, the shaft portion 25a of the tightening bolt 25 is penetrated from one of the shaft holes 12a of the both leg pieces 12, and the tightening nut 26 is lightly tightened from the distal end side of the tightening bolt 25 to be in a temporarily fixed state. The bolt body B is inserted and inserted through the gap between the both sandwiching pieces 13 from above the bolt body B erected on the roof Y (see FIGS. 2A and 2B).

  Next, when the tightening bolt 25 and the tightening nut 26 that have been temporarily fixed are tightened, both the leg pieces 12 are brought close to each other by the tightening force, and both the sandwiched pieces 13 are also brought close to each other. The upper and lower two-stage locking pieces 15 provided at the front ends of the bolts are locked in the thread grooves on the outer peripheral surface of the bolt body B so as to sandwich the bolt body B.

  In particular, in this embodiment, since the locking piece 15 that can be bitten and locked into the thread groove of almost the entire circumference of the shaft portion B1 of the bolt body B is formed, the locking force becomes strong. The clamping body 1 can be securely attached to the bolt body B by firmly clamping the bolt body B with the clamping piece 13 (see FIG. 3A).

  Various devices and members D can be attached above the upper plate 11 of the rooftop fixture A thus attached to the folded plate roof Y by means of a sword bolt 3 or the like standing on the upper plate 11 (FIG. 3 ( b)).

  As described above, according to the on-roof mounting tool A of the present invention, the upper and lower two-stage locking pieces 15 formed at the front ends of the sandwiching pieces 13 are respectively locked in the thread grooves of the bolt body B. In addition, the recess 14 is fitted to the outer peripheral surface of the bolt body B, so that the on-roof fixture A can be easily and reliably attached to the bolt body B.

  Further, the sandwiching tool 1 is integrally formed including the leg piece 12 formed by bending the sandwiching piece 13 at the lower end and the upper plate 11 having the leg pieces 12 at both ends. 1 can be constructed in a sturdy and simple shape. Moreover, since it is integrally formed, the possibility of deviation is low. Further, since the pair of leg pieces 12 are tightened to bring the pair of sandwiching pieces 13 close to each other, it is only necessary to use a tightening bolt 25 or the like for tightening the pair of leg pieces 12. Can be simplified. In addition, since it is also possible to make the upper plate 11 into a flat shape without standing the sword bolt 3, the upper portion of the upper plate 11 can be used in various modes.

  FIG. 4 is a perspective view showing another construction example of the on-roof fixture A, and FIG. 5 is a partial cross-sectional front view after the roof-top fixture A is attached to the folded plate roof Y in the construction example. FIG.

  Here, the parts common to FIGS. 1 to 3 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, a round goby projecting in a substantially circular cross section on the upper surface of the folded plate roof Y as a connecting structure of the folded plate roof Y using the on-roof fixture A shown in FIGS. It shows what is connected by a goby part C of the mold. In addition, since it is the same also about the square goby etc. which protruded in the cross-section substantially L shape on the upper surface of the folded-plate roof Y, it abbreviate | omits description about a square goby.

  Specifically, when attaching the on-roof fixture A of the present invention to the goby portion C, the front end portion 13a formed in two stages of the sandwiching piece 13 is not the folded piece roof Y, instead of the locking piece 15. It will be attached to the leg C1 formed on the goby part C.

  Therefore, this on-roof fixture A has a structure having a two-stage locking piece 15 for being clamped to the bolt body B, but also to the goby portion C formed on the top Y1a by goby type joining. Can be installed without problems. Of course, since there is a goby portion C, the on-roof fixture A is not likely to come off.

  Next, a second embodiment will be described.

  FIG. 6 is an explanatory view of the second embodiment of the rooftop fixture according to the present invention, and is a perspective view showing a state before the rooftop fixture is attached to the corrugated roof. FIG. 7 is an exploded perspective view of the roof mounting tool. FIGS. 8A, 8B, 9A, and 9B are partial cross-sectional front views showing a construction state of the on-roof fixture shown in FIG.

  8A is a partial cross-sectional front view showing a state before the rooftop fixture A is attached to the corrugated roof, and FIG. 8B is a diagram showing that the rooftop fixture is inserted into the corrugated roof bolt body. FIG. 9A is a partial cross-sectional front view showing a state in which the roof top fixture A is attached to the bolt body of the folded plate roof, and FIG. The partial cross-sectional front view which shows the state which further attached various apparatuses and members D to the tool A is shown, respectively.

  As the corrugated roof to which this on-roof fixture A is attached, the folded plate roof Y (angular corrugated roof) and the round corrugated roof shown as examples are mentioned as in the first embodiment. Moreover, as materials for the roof, metals, synthetic resins, cement-based materials and the like can be applied.

  Further, the folded plate roof Y, which is the attachment target of the on-roof fixture A, is the same as the folded plate roof Y shown in the first embodiment, and the structure thereof is denoted by the same reference numerals and description thereof is omitted. To do.

  This on-roof mounting tool A constitutes a sandwiching tool 1 ′ by connecting a pair of sandwiching members 10 so as to be openable and closable, and a pair of opposing sandwiching pieces that are the working points of the sandwiching tool 1 ′. 13 is a fixture having a structure in which 13 is fixed close to each other and clamped to a bolt body B protruding from the top Y1a of the folded plate roof Y, and the top Y1a of the folded plate roof Y is attached to the tip of the clamped piece 13. The locking piece 15 that can be locked to the outer peripheral surface of the bolt body B protruding from the upper surface of the bolt body B is formed in two steps in the vertical direction.

  First, the overall structure of the sandwiching tool 1 ′, which is a feature of the present invention, excluding the sandwiching structure to the bolt body B by the two-stage locking pieces 15 provided at the tip of the sandwiching piece 13 will be described.

  Each of the pair of sandwiching members 10 constituting the sandwiching tool 1 ′ has an upper plate 11 in which a bolt through hole 11 e is opened at the center and a cut groove 11 d is formed from the bolt through hole 11 e to one side edge. The leg piece 12 is bent from the base end of the upper plate 11 and extends downward, and the sandwiching piece 13 extends from the lower end of the leg piece 12 in substantially the same direction as the upper plate 11.

  The sandwiching tool 1 ′ is arranged such that the top ends of the top plates 11 are arranged below the base end of the top plate 11 of the mating member with the top plates 11 of the two sandwich members 10 facing each other. Next, the slits 11d of the upper plate 11 are inserted into each other so that both the upper plates 11 are swingably engaged with each other so that the bolt through holes 11e are aligned with each other. By passing the bolts 21 and screwing the tightening nuts 22, the ends of the sandwiching pieces 13 are brought close to each other.

  Here, as shown in the figure, a rounded round head bolt may be used as the clamping tool clamping bolt 21. As the clamping nut 22, a nut 22a rotates on the top surface of a hat-shaped washer 22b. A nut with a washer attached freely may be used. The bolt stop 23 is made of synthetic resin or the like, and a plurality of cuts 23b are formed on the periphery of the hole 23a.

  Summarizing the above structure, the two clamping members 10 are connected to each other in a crossing manner by a cut groove 11d formed in the upper plate 11, and two upper members from above and below are clamped by a clamping tool clamping bolt 21 and a clamping nut 22. By tightening the plate 11, the tip of the upper plate 11 serving as a power point is expanded with the cut groove 11 d as a fulcrum, and the two upper plates 11 in an intersecting state are made closer to a flat plate shape, thereby both acting as the action points. It has a deformed scissor structure in which the sandwiching pieces 13 are brought close to each other.

  More specifically, as shown in FIG. 7, the upper plate 11 includes a flat base end portion 11a, a step portion 11c formed on the front end side of the base end portion 11a, and a step portion 11c. Furthermore, a distal end portion 11b formed on the distal end side and located at a position lower than the base end portion 11a by about one sheet thickness is provided. In addition, a long hole extending across the base end portion 11a and the front end portion 11b around the stepped portion 11c is provided at substantially the center of the upper plate 11, and this long hole constitutes the bolt through hole 11e. Further, a pressing claw 11f cut and raised downward is formed on the end portion side of the long hole at the distal end portion 11b side. The cut groove 11d communicating with the bolt through hole 11e is formed along the step portion 11c. It is desirable that the upper plate 11 has a gentle forward inclination as a whole.

  In this way, the stepped portion 11c is formed along the bolt through hole 11e and the cut groove 11d provided in the center of the upper plate 11, so that when the front end portion 11b of the upper plate 11 is opened, the step 2c is polymerized. The upper plate 11 of the sheet is substantially flat, and the gap between the base end portion 11a of the upper plate 11 and the distal end portion 11b of the upper plate 11 of the counterpart clamping member 10 becomes smaller, and there is no possibility of wobbling. , A more stable shape can be obtained.

  According to such an on-roof fixture A, the sandwiching tool 1 'is composed of the two sandwiching members 10, and they are connected to the fulcrum so that they can be opened and closed. When the nut 22 is in a loose state, the two clamping members 10 are also in a loose state. Therefore, in order to fix the sandwiching piece 13 in the closed state, it is only necessary to fasten the fastening nuts 22 to fix the upper plates 11 together, and the workability is good.

  Next, a structure for clamping the bolt body B with the clamping piece 13 of the roof mounting fixture A, which is a feature of the present invention, will be described.

  Locking pieces 15 that can be locked to the outer peripheral surface of the shaft portion B1 of the bolt body B are formed in two steps in the vertical direction at the tip of the sandwiching piece 13. Specifically, the front end of the sandwiching piece 13 is formed in two steps by folding the plate piece, and the locking piece 15 having the same shape is formed at each of the two ends.

  That is, the structure of the two-stage locking piece 15 is the same as that of the on-roof fixture A of the first embodiment, and the same effect is produced. The enlarged plan view around the locking piece 15 is the same as that shown in FIG.

  Further, since the on-roof fixture A is composed of a sandwiching tool 1 ′ composed of two sandwiching members 10, when the sandwiching piece 13 is brought close to the sandwiching object 13 in the absence of a sandwiching target, the bolt penetration of the upper plate 11 is performed. Although there is a possibility that the tips of both sandwiching pieces 13 are displaced in the horizontal direction due to play or the like formed in the hole 11e, the bolts B are sandwiched by the locking pieces 15 and the recesses 14 formed in two steps. Since it is a structure, as long as the bolt body B is an object to be clamped, there is no possibility of such a shift. Even if the bolt body B is clamped in a state where there is a slight shift, the shift does not increase because the bolt body B is fitted by the recess 14 in the upper and lower two stages.

  The on-roof fixture A of the present invention configured as described above is used by being attached to the folded plate roof Y in the following manner.

  First, in the state where both the sandwiching pieces 13 of the sandwiching tool 1 ′ are sufficiently opened in the on-roof mounting tool A, that is, the two fasteners are loosened by loosening the fastening bolts 21 and the fastening nuts 22. The member 10 is connected to a fulcrum so that it can be opened and closed, and the bolt body B is inserted from above the bolt body B erected on the folded plate roof Y through the gap S between the both sandwiched pieces 13 (FIG. 8A ), See (b)).

  Next, when the clamping tool clamping bolt 21 and the clamping nut 22 that have been temporarily fixed are tightened, the upper plates 11 that are overlapped in a swingable and loose state are flattened.
