  Hereinafter, the best mode for carrying out the present invention will be described.

  When the heat insulating roof connector A according to the present invention forms a heat insulating roof having a high heat insulating property between the upper roof material 30 and the lower roof material 31, the upper roof material 30 and the lower roof are formed. It is used to connect the material 31 in a separated state. As such a heat insulating roof, a double folded plate roof can be exemplified, and in this case, as the upper roof material 30 and the lower roof material 31, a conductive metal plate such as a coated steel plate or a galvanized steel plate is rolled. A folded plate formed by bending or the like can be used.

  The insulated roof connector A according to the present invention includes a saddle 1, a hanger 2, a heat insulating member 3, and a conductive member 4.

  As shown in FIGS. 2 (a) and 2 (b), the saddle 1 is formed by connecting a pair of saddle halves 10 and 10 with a connecting tool 11 such as a bolt. The saddle half 10 is formed by bending a conductive metal plate such as a stainless steel plate or a plated steel plate, and a holding portion 13 having a substantially semicircular cross section is formed at the upper end of a rectangular plate-like support piece 12. The mounting piece 14 is provided at the lower end of the support plate 12. A screw hole 44 is formed in the support plate 12. Both the holding portion 13 and the mounting piece 14 protrude outward from one surface of the support plate 12. Further, one of the pair of saddle halves 10 and 10 is provided with a tightening engagement portion 15. The clamping engagement portion 15 is formed to be bent in a substantially square cross section at the lower portion of the support piece 12 and is formed to protrude from the surface of the support plate 12 in the same direction as the holding portion 13 and the mounting piece 14.

  As shown in FIG. 3, the suspension 2 is formed by bending a conductive metal plate such as a stainless steel plate or a plated steel plate, and a mounting piece 17 is formed at the lower end of the rectangular plate-like slide piece 16. 17 is provided in a protruding manner, and a protruding piece 18 is provided at the upper end of the slide piece 16 so as to protrude substantially vertically, and a locking piece 19 that protrudes obliquely downward from the tip of the protruding piece 18 toward the slide piece 16 is provided. ing. The mounting piece 17, the protruding piece 18, and the locking piece 19 are provided over the entire length in the longitudinal direction of the hanging piece 2 (slide piece 16). Further, a plurality of protrusions 20, 20... Are arranged on both surfaces of the slide piece 16 in the longitudinal direction of the slide piece 16. Further, drop-off prevention pieces 21 are projected at both ends of the mounting piece 17 in the longitudinal direction.

  The heat insulating member 3 has a non-heat transfer property in which heat is less likely to be transmitted than the saddle 1 and the suspension 2, and can be formed of a molded product of plastic such as ABS resin, for example. The heat insulating member 3 includes a held portion 22 whose outer shape is substantially oval, and a pair of guide pieces 23 and 23 projecting from the upper surface of the held portion 22 over the entire length in the longitudinal direction. In addition, the held portion 22 is formed with guide grooves 24 that open to both end surfaces and the upper surface in the longitudinal direction. The opening of the guide groove 24 on the upper surface of the held portion 22 is formed between the pair of guide pieces 23 and 23 along the longitudinal direction of the guide piece 23.

  The conductive member 4 may be anything as long as it is formed of a conductor such as aluminum, iron, or copper, and can be arbitrarily formed in a linear shape or a plate shape. For example, as the conductive member 4, it is possible to use a covered conductor or the like provided with connection fittings 25 and 25 at both ends.

  And the connector A for heat insulation roof of this invention is formed as follows. The saddle 1 is formed by connecting a pair of saddle halves 10 and 10 facing each other with a coupler 11. At this time, the pair of saddle halves 10 and 10 are arranged so that the inner surfaces of the support plates 12 and 12 (the surfaces opposite to the surfaces from which the holding portions 13 and the mounting pieces 14 protrude) are aligned with each other. 11 can be connected by screwing. Further, the heat insulating member 3 is sandwiched and held between the saddle halves 10 and 10 coupled as described above. At this time, the held portion 22 of the heat insulating member 3 is fitted inside the holding portion 13 of the saddle half 10, and the held portion 22 is interposed between the holding portions 13 and 13 of the opposing saddle halves 10 and 10. Intervene. Therefore, the guide pieces 23 and 23 of the heat insulating member 3 are interposed between the upper ends of the opposing holding portions 13 and 13.

  After the saddle 1 and the heat insulating member 3 are integrated as described above, the hanger 2 is attached to the heat insulating member 3. At this time, as shown in FIG. 4, the mounting pieces 17, 17 of the suspension 2 are inserted into the guide groove 24 and the slide piece 16 of the suspension 2 is positioned on the guide pieces 23, 23 of the heat insulating member 3. Thus, the suspension 2 can be attached to the saddle 1 and the heat insulating member 3 as a slide suspension so as to be slidable in the longitudinal direction. Further, the drop-off preventing pieces 21 at both ends in the longitudinal direction of the mounting piece 17 are bent downward while the mounting piece 17 is inserted into the guide groove 24. As a result, the drop-off prevention piece 21 is hooked on the opening edge of the guide groove 24, so that the mounting piece 17 can be prevented from coming out of the guide groove 24, and the hanger 2 from the saddle 1 and the heat insulating member 3. Can be prevented from falling off.

  After integrating the saddle 1, the heat insulating member 3, and the hanging member 2 as described above, the saddle 1 and the hanging member 2 are electrically connected by the conductive member 4, thereby connecting the insulating roof coupling tool of the present invention. A can be formed. Here, the connection fitting 25 at one end of the conductive member 4 can be connected to the support plate 12 of the saddle 1, and the connection fitting 25 at the other end of the conductive member 4 can be connected to the drop-off prevention piece 21 of the suspension 2. The connection position of the connection fitting 25 is not particularly limited to the support plate 12 or the drop-off prevention piece 21 and may be another part. The conductive member 4 has a sufficient length and flexibility so that the suspension 2 can slide over the entire length thereof. Moreover, the connection method of the connection metal fitting 25 can employ | adopt methods, such as welding and a screw stop.

  In the heat insulating roof connector A of the present invention, the saddle 1 and the suspension 2 are not in direct contact with each other because the heat insulation member 3 having non-thermal conductivity (heat insulation) is interposed between the saddle 1 and the suspension 2. 1 and the suspension 2 can be cut off from heat conduction so that there is almost no heat bridge between the upper roof material 30 and the lower roof material 31. A heat insulating roof having high heat insulating properties can be formed. Further, since the saddle 1 and the suspension 2 are not in direct contact with each other, when a non-conductive member such as plastic is used as the heat insulation member 3, the conduction of the saddle 1 and the suspension 2 is blocked by the heat insulation member 3. In the insulated roof connector A of the present invention, since the saddle 1 and the suspension 2 are electrically connected by the conductive member 4, the conductivity of the saddle 1 and the suspension 2 can be ensured.

  When forming a double folded plate roof as a heat insulation roof using the connector A for heat insulation roof of this invention, it carries out as follows. As the upper roof material 30 and the lower roof material 31 forming the heat insulating roof, a folded plate 49 as shown in FIG. 5 can be used. The folded plate 49 is formed by bending a metal plate such as a coated steel plate or a galvanized steel plate, and is formed long in the inclination direction (flow direction) of the roof. The folded plate 49 has a substantially U-shaped cross section, and includes a flat trough portion 50 and connecting mountain portions 51 and 51 projecting obliquely upward from both sides thereof. The upper part of one connection peak part 51 has a top piece 52 projecting toward the opposite side to the trough part 50, and a fitting part 53 having a substantially inverted U-shaped cross section projecting upward from the end of the top piece 52. It consists of and. Moreover, the upper part of the other connection peak part 51 has the top piece 52 which protrudes toward the opposite side to the trough part 50, and the cross-section substantially reverse L-shaped fitting which protrudes upwards from the edge part of the top piece 52. And a joint portion 54. Then, by fastening the fitting portion 53 and the fitted portion 54 after fitting, the connecting mountain portions 51, 51 of the adjacent folded plates 49, 49 are connected to each other, and the adjacent folded plates 49, 49 are connected. Can be connected. Moreover, it becomes the folded-plate roof which the mountain part 55 and the trough part 50 which consist of the connected connection mountain parts 51 and 51 repeated alternately.

  First, the tight frame 41 is attached on the roof base 40 such as a beam or a purlin. The roof base 40 can be formed of H-shaped steel or the like, and the tight frame 41 can be formed by bending a metal plate such as a coated steel plate or a galvanized steel plate, both of which are made of an electrically conductive metal material. Is formed.

  Next, a plurality of folded plates 49, 49... Are placed on the roof base 40 from the upper side of the tight frame 41 while arranging them as a lower roof material 31 in a direction perpendicular to the slope direction (inclination direction) of the roof. To do. Further, the lower roof material 31 is constructed so as to extend between a plurality of roof bases 40, 40,. Here, the valley 50 of the lower roof material 31 is positioned between the adjacent peaks 65, 65 of the tight frame 41, and the connecting peaks 51 are positioned along substantially the half outer surface of the peaks 25. Each lower roof material 31 is arranged. Further, the lower roof materials 31 and 31 adjacent to each other with the mountain portion 25 sandwiched between the fitting portion 53 and the fitted portion 54 as described above are tightened, thereby connecting the mountain portion 51, 51 are connected and connected to each other, but the state in which the fixed hanger 48 provided on the peak portion 65 of the tight frame 41 is sandwiched between the fitting portion 53 and the fitted portion 54 when tightening is performed. Tighten with. In this way, by connecting and fixing the plurality of folded plates 49 (lower roof material 31) to the roof base 40 via the fixed hanger 48 and the tight frame 41, the lower side of the double folded plate roof is fixed. A folded plate roof can be formed. The fixed suspension 48 can be formed by bending a metal plate such as a coated steel plate or a galvanized steel plate, and is formed of a metal material having electrical conductivity. Accordingly, the lower roof material 31 is electrically connected to the tight frame 41 and the roof base 40 directly or via the fixed suspension 48. In this case, even if a coating film is formed on the surfaces of the roof base 40, the tight frame 41, the fixed hanger 48, and the lower roof material 31, the coating film is so thin that it does not become an insulator.

  After forming the lower folded-plate roof as described above, the saddle 1 of the connector A for heat-insulating roof of the present invention is attached to the top of the mountain portion 55 of the lower folded-plate roof. At this time, although the heat insulating member 3 is attached to the saddle 1, the hanging member 2 and the conductive member 4 are not attached. In addition, the saddle 1 is sandwiched between saddle halves 10 and 10 with a tightening portion 47 (a tightened portion between the fitting portion 53 and the fitted portion 54) formed at the top of the mountain portion 55 of the lower folded plate roof. Can be attached. That is, the saddle fastening members provided on one saddle half 10 and the saddle half 10 are arranged on both sides of the fastening portion 47 while the placing piece 14 of the saddle half 10 is placed on the top piece 52. By inserting and engaging the tightening portion 47 into the joint portion 15, the coupling tool 11 is screwed and tightened so as to penetrate the support pieces 12 and 12 of the saddle halves 10 and 10 on the upper side of the tightening portion 47. The saddle tightening portion 47 is sandwiched between the saddle halves 10 and 10, and the saddle 1 can be attached to the top of the mountain portion 55. Also, the saddle 1 is fixed by connecting the lower portions of the support pieces 12 and 12 of the saddle halves 10 and 10 to the connected fitting portion 53 and fitted portion 54 with a fixture 46 such as a screw or bolt. Can do. The saddle 1 is electrically connected to the lower roof material 31 by contact between the tightening portion 47 and the tightening engagement portion 15, contact between the support plate 12 and the mountain portion 55, and the fixture 46. In this case, even if a coating film is formed on the surface of the saddle 1 or the lower roof material 31, the coating film is so thin that it does not become an insulator.

  After the plurality of saddles 1, 1,... Are attached to the lower folded plate roof as described above, the heat insulating material 56 is disposed on the lower folded plate roof. As the heat insulating material 56, an inorganic fiber body such as rock wool or glass wool or a resin foam such as urethane foam or phenol foam can be used. The heat insulating material 56 is spread over the entire upper surface of the lower folded plate roof. Further, the saddle 1 attached to the lower folded plate roof is in a state in which the lower part of the saddle 1 is covered with the heat insulating material 56, and the holding portion 13 and the heat insulating member 3 are more than the spread heat insulating material 56. Located on the upper side.

  Next, the single folded plate 49 is placed on the heat insulating material 56 as the upper roof material 30. At this time, like the lower roof material 31, the upper roof material 30 is arranged with the roof inclination direction (flow direction) as the long direction. Further, the fitted portion 54 of the upper roof material 30 is located on the side of the saddle 1 attached to the lower folded plate roof, and the longitudinal direction of the fitted portion 54, the longitudinal direction of the guide groove 24, and the guide piece. 23 is substantially parallel to the longitudinal direction.

  Next, the locking piece 19 of the hanging element 2 is locked to the lower side of the fitted portion 54 of the upper roof material 30 placed on the heat insulating material 56 and the hanging element 2 is brought close to the upper roof material 30. By inserting into the heat insulating member 3 of the saddle 1 positioned, the upper roof material 30 is locked to the heat insulating roof connector A composed of the saddle 1 and the suspension 2. Here, the drop-off prevention piece 21 formed on one side in the longitudinal direction of the hanging element 2 is bent downward, and the connection fitting 25 at one end of the conductive member 4 is connected to the drop-off prevention piece 21 by welding or the like. ing. Accordingly, the hanging element 2 is inserted between the guide groove 24 of the heat insulating member 3 and the guide pieces 23 and 23 from the unfallen falling prevention piece 21 and is not bent after the hanging element 2 is inserted into the heat insulating member 3. The one falling prevention piece 21 is bent downward. In this case, even if a coating film is formed on the surface of the upper roof material 30, the coating film is so thin that it does not become an insulator.

  After the suspension 2 is attached to the saddle 1 as described above, the connection fitting 25 at the other end of the conductive member 4 connected to the suspension 2 is connected to the saddle 1 as shown in FIG. At this time, since the heat insulating material 56 is flexible, the heat insulating material 56 is pushed down to expose the support piece 12 of the saddle 1, and the connection fitting 25 of the conductive member 4 is attached to the outer surface of the support piece 12 with screws or the like. To. Thereafter, the pressed portion of the heat insulating material 56 is returned to cover the support piece 12 of the saddle 1. In FIG. 1, the heat insulating material 56 is not shown.

  Next, another upper roof material 30 different from the above is further placed on the heat insulating material 56, and is adjacent to the upper roof material 30 locked to the hanging element 2. And the to-be-fitted part 54 of the upper roof material 30 latched by the said hanging element 2, and the protrusion piece 18 and the latching piece 19 of the hanging element 2 of the fitting part 53 of the upper roof material 30 which newly mounted. It is housed inside and fitted, and then the fitting portion 53 and the fitted portion 54 are tightened to connect and connect the connecting mountain portions 51 and 51 of the adjacent upper roof materials 30 and 30 to each other. To do.

  In this way, by alternately attaching the suspension 2 to the saddle 1 and laying the upper roof material 30 on the heat insulating material 56, the upper folding member to which the plurality of upper roof materials 30, 30. A plate roof can be formed. And between the upper folded-plate roof and the lower folded-plate roof is formed as the heat insulation space 32 with which the heat insulating material 56 was filled, and the double folded-plate roof with high heat insulation can be formed. In addition, the upper folded plate roof is connected to and supported by the lower folded plate roof by the heat insulating roof connector A.

  In the heat insulating roof of the present invention, the upper roof material 30, the suspension 2, the conductive member 4, the saddle 1, the lower roof material 31, the tight frame 41, and the roof base 40 are all electrically connected. The roof base 40 is electrically connected to a building frame such as a pillar, and the building frame is grounded to the ground via a foundation frame and the like. Therefore, when there is a lightning strike on the upper roof material 30, a lightning current can be caused to flow to the ground through each of the above members, and lightning can be prevented using a heat insulating roof. Further, the entire heat insulating roof having a larger area than the lightning protection equipment such as a lightning rod can serve as a lightning receiving portion, and lightning protection performance can be improved. Furthermore, even if it is a roof construction contractor using the insulated roof connector A and the process for forming a heat insulating roof, a lightning protection structure can be easily formed, and by reducing the number of members and shortening the construction process Cost can be reduced.

  In the heat insulating roof of the present invention, when the upper roof material 30 expands and contracts in the inclination direction of the roof, the suspension 2 is slid in the inclination direction (flow length direction) of the roof with respect to the saddle 1 accordingly. Can do. Therefore, the movement of the upper roof material 30 is not restrained by the expansion and contraction. Therefore, even if the upper roof material 30 is thermally expanded and contracted due to external heat factors such as outside air temperature, radiant heat of the sun, and wind and rain, the upper roof material 30 The internal stress is not accumulated in the 30 itself, or the internal stress is not concentrated on the oblique side or the tightened portion of the upper roof material having low rigidity, so that the displacement and deformation are less likely to occur. Can be prevented.

  7 and 8 show another embodiment. In this insulated roof connector A, one end of the conductive member 4 is connected to the side surface of the slide piece 16 of the suspension 2 by welding or screwing. Further, as shown in FIG. 8A, a connection plate 60 is connected to the other end of the conductive member 4. The connection plate 60 is formed in a rectangular plate shape with a conductor such as aluminum, iron, or copper, and the conductive member 4 is connected to one short side, and the semi-circle is formed on the other short side. A notch 61 is formed. Around the cutout portion 61, a locking portion 62 is formed by cutting and raising. The locking part 62 prevents the coupler 11 from loosening. Note that, as shown in FIG. 8B, a locking washer 63 for locking the coupler 11 may be provided around the notch 61 instead of forming the locking portion 62 by cutting and raising. Other configurations of the saddle 1 and the heat insulating member 3 are the same as described above.

  When forming a double folded plate roof as a heat insulation roof using this connection tool A for heat insulation roofs, it carries out as follows. First, after the lower folded plate roof 31 is formed in the same manner as described above, the saddle 1 is attached, and the heat insulating material 56 is further disposed. Next, in the same manner as described above, the single folded plate 49 is placed on the heat insulating material 56 as the upper roof material 30. Next, in the same manner as described above, the locking piece 19 of the hanging element 2 is locked to the lower side of the fitted portion 54 of the upper roof material 30 placed on the heat insulating material 56 and the hanging element 2 is attached to the upper roof. By inserting into the heat insulating member 3 of the saddle 1 located in the vicinity of the material 30, the upper roof material 30 is locked to the heat insulating roof connector A composed of the saddle 1 and the hanger 2. After the suspension 2 is attached to the saddle 1 in this way, as shown in FIG. 7, the connection plate 60 provided at one end of the conductive member 4 connected to the suspension 2 is electrically connected to the saddle 1. . In this case, the connection plate 60 is inserted between the support pieces 12 and 12 of the pair of saddle halves 10 and 10, and the notch 61 is inserted into the coupler 11 from the side. Is held between the support pieces 12 and 12. Thereafter, another upper roof material 30 is further placed on the heat insulating material 56 in the same manner as described above. Then, by alternately attaching the suspension 2 and the connection plate 60 to the saddle 1 and laying the upper roof material 30 on the heat insulating material 56, the upper side where the plurality of upper roof materials 30, 30. A double folded plate roof similar to the above can be formed.

  In this embodiment, the connection plate 60 is connected to the suspension 2 in advance by the conductive member 4 before construction, and after the connection plate 60 is inserted between the support pieces 12, 12, the coupler 11 is tightened. Thus, the saddle 1 and the suspension 2 can be electrically connected by the connection plate 60 and the conductive member 4, and can be easily constructed even by a roof construction company. Note that the connecting plate 60 may be fixed in close contact with the outer surface of the support plate 12 as shown in FIG. 9 without being inserted between the support pieces 12 and 12.

  In the above description, the suspension 2 is slid with respect to the saddle 1. However, the present invention is not limited to this, and as shown in FIG. Even when fixed and does not move, the saddle 1 and the suspension 2 can be electrically connected using the conductive member 4.
