Description

  TECHNICAL FIELD The present invention relates to a fitting roof material (including both vertical and horizontal), and a method for connecting the roof material, which are widely used in roofs of ordinary houses, offices, condominiums, welfare facilities, resort facilities, and the like. It is.

  In general, it is common for vertical roofs to use long and narrow roofing materials that are long in the beam-to-beam direction (the direction along the ridge) and short in the beam direction (the direction along the ridge). Then, after the connection between the roofing materials in the beam-to-beam direction is completed, the operation of connecting the roofing materials in the girder direction is repeated, and the entire roof is lifted up.

  On the other hand, it is common to use a roof with a roof that is long in the girder direction, short in the beam direction, and wide in the girder direction, and after connecting the roof materials in the girder direction, By repeating the work of connecting the roofing materials in the direction, the entire roof is rolled up.

  Although this kind of roofing material has a difference in the method of roofing, all of them are produced continuously by roll-forming long coils, especially for vertical roofing. The roofing material is often manufactured as a single piece having the same length as the roof in order to eliminate the need for connecting the roofing materials in the beam-to-beam direction in consideration of waterproofness.

  By the way, for roofing materials for vertical roofs made of a single piece, when the roof is lifted up in a house located in the center of a city, it is difficult to carry in due to the narrow road, or under construction For example, it is difficult to secure a working space (such as a surrounding open space) to be used, and there are cases where it is difficult to increase demand.

  As a prior art for solving such a conventional defect, for example, in Patent Document 1, a curved metal roof plate is formed in a substantially semi-cylindrical shape on a tile bar provided on a roof base plate. The front edge part which fitted the reinforcing material with a part and taper-shaped on the back side except for both right and left ends, and formed the male part for a lock, the S-shaped flattened female part, a plurality The ridge for rain return and the rear edge folded back to the surface side in the left-right direction and in the direction of the rear edge sequentially, and bent symmetrically and expanded in the left-right direction at the upper end It is composed of left and right rising parts that form curved parts, and is between the roof tiles, from the eaves of the roof to the ridge, and the male part at the front edge of the metal roofing board is turned over from the other roofing board. From the lower ends of the left and right reinforcements that are inserted into and engaged with the part and the left and right rising parts are fitted to the brick In order to contact and cover the curved part, laying while connecting a plurality of metal roofing plates in sequence, and then extending the tile rod in the longitudinal direction from the reinforcing material and the lower end of the reinforcing material to the curved part There has been proposed a method for laying a metal roof board in which the rising parts of the metal roof board in contact with and covering are sequentially covered with a plurality of wrapping materials.

  Further, in Patent Document 2, a vertical roofing roof plate that is fixed in the flow direction in which engaging portions are formed on the left and right side edges is connected in the flow direction via a joint member, and the vertical roofing roof board is connected in the left-right direction. With respect to a vertical roof that disposes a drainage member having a flowing water space below the section, the joint member is disposed in a discarding plate member and a discarding plate member whose side end faces the flowing water space of the drainage member, A water-stopping member having at least one groove formed thereon, an eaves-side end portion of the vertical roofing sill laid on the ridge side of the joint member, and a vertical roofing slab similarly laid on the eaves side Each of the ridge-side end portions of the ridge side is formed with folded portions, and these folded portions are inserted into the groove portions of the water-stopping member, and the longitudinal roofing roof plates adjacent to each other in the flow direction are connected to each other. In addition, in Patent Document 3, a face plate portion is provided at the center portion, and inner side stands at left and right side edges thereof. An outside rising part is provided via a drainage groove on the outside of the inside rising of the vertical wall covering material for building provided with a ridge, and the holding member and the elastic member are provided at either the upper end or the middle of the outside rising part or both. 2. Description of the Related Art An architectural vertical covering material and an outer layer structure have been proposed in which an engaging part engaging part that engages with the structure is formed.

Further, the present invention is a method for connecting a fitting roof material having the above configuration,
The upper joint provided on the short edge of the roof material main body is overlaid on the short edge of another roof material arranged adjacent to the underwater side, and the third goby and the fourth goby are placed under the water. Fitting the upper and lower gores of other roofing materials adjacent to the side and folding back the hanging locking piece, then, to the lower joint provided at the short edge of the roofing material body, on the water side Overlapping short edges of other roofing materials arranged adjacent to each other, the upper goby and lower goby of other roofing materials arranged adjacent to the water side are fitted to the first goby and the second goby, and the standing It is a connection method of the fitting type roofing material characterized by connecting roofing materials in the beam-to-beam direction by folding back the locking pieces.

  According to the present invention, when the roofing materials are joined together in the beam-to-beam direction, the standing locking piece of the lower joint and the hanging locking piece of the upper joint are folded back so that they are adjacently arranged on the water side and the water side, respectively. Since it links with the material, the roof material can be reliably connected without requiring an extra member. In particular, when the hanging locking piece is folded back, the short edge portion of the roof material main body becomes a two-layered (180 ° bent) state, the rigidity is increased, and deformation of the roof material such as a convex shape can be avoided.

  Further, according to the present invention, the waterproof packing is provided at both ends and the lower end of the hanging locking piece or the entire surface thereof. Even if the gap size changes due to dimensional variations (changes in shape due to long-term use of the mold, etc.), it is possible to fill the gap formed in the overlapping part (connection part) and ensure rainwater intrusion. This can be avoided and can be scaled.

  Further, according to the present invention, the lower joint is provided with a waterproof packing in the region from at least the top of the first goby to the at least the top of the second goby through the plate, or the upper joint, The region from the top of the inner wall of the third goby to the end of the first plate in the width direction and the end of the fourth goby from the top of the inner wall to the other end of the first plate Since the waterproof packing is provided in each of the areas up to, the rainwater flow from the overlapping portion of the roofing material can be blocked even in this case.

  In addition, according to the present invention, the hanging locking piece has a length equal to or longer than the standing locking piece, so that it is possible to increase the linkage strength of the roofing material and waterproof. Expansion of packing installation range (enlargement of seal area) can be achieved.

  Further, according to the present invention, since the angle between the standing locking piece and the outer surface of the plate-like body is set to 0 to 45 °, a large force is not required when the roof materials are joined together. It is possible to fold up the standing locking piece, and the work of lifting the roof becomes easy. In addition, when the standing locking piece is folded back from the beginning (bending at 180 °), it becomes difficult to hook the standing locking piece and the hanging locking piece, and the surface treatment layer of the roofing material is damaged. Therefore, the angle formed with the outer surface of the plate-like body is preferably more than 0 ° and not more than 45 °, more preferably 5 to 45 °.

  When the hanging locking piece is provided, the waterproof packing is bent after the waterproof packing is applied, so that no wrinkles or thickness variations occur in the waterproof packing. In addition, an angle formed by the bending process after the waterproof packing is pasted and the back surface of the first plate-like body of the hanging locking piece is 0 to 45 °, preferably more than 0 ° and not more than 45 °, more preferably By setting the angle to 5 to 45 °, it is possible to fall down without applying a large force to the hanging locking piece when joining the roofing materials, and the roof of the building structure can be lifted up efficiently. .

  In addition, in the roof material having waterproof packing on the upper surface of the folding latch piece, since the folding process of the portion that becomes the folding latch piece is only once, the standing latch piece is formed by bending, and the standing latch is formed. The manufacturing process can be shortened as compared with the case where the standing locking piece is bent again to an angle of 180 ° after the prevention packing is attached to the inside of the piece.

  Furthermore, according to the connection method of the fitting type roofing material of the present invention, the upper joint provided on the short edge of the roofing material main body is overlapped with the short edge of the other roofing material disposed adjacent to the water-lowering side. The third goby and the fourth goze are fitted to the upper goby and the lower goze of the other roofing material arranged adjacent to the water-lowering side, and the hanging locking piece is folded back, and then the short length of the roofing material main body Overlay the short edge of the other roofing material that arranges the lower joint provided on the edge adjacent to the waterside, and the other roofing material adjacent to the waterside on the first goby and the second goby. The roofing materials are connected in the beam-to-beam direction by fitting the upper and lower seams and folding up the standing locking pieces, so the connecting work between the roofing materials is relatively simple and requires extra members. I don't have to.

  As for the waterproof packings 6 to 10, the case where the waterproof packings 6 to 10 are provided on either the lower joint 4 or the upper joint 5 is shown. However, it is also possible to affix the prevention packing to both the lower joint 4 and the upper joint 5. There is no limitation to the above.

  The second goby 4c constituting the lower joint 4 has a tongue piece 4e connected to the fixing tongue 3d of the lower goby 3 via a step d3 at the lower end thereof (similar to the fixing tongue 3d). The second goby 4c itself has a relatively high rigidity, and depending on its size, when fitting the fourth goby 5c of the upper joint 5 of another roof material adjacent to the second goby 4c, There is also a concern that the waterproof packing 8 attached to the inner wall of the fourth goby 5c may be peeled off. For this reason, as shown in FIGS. 16 (a) and 16 (b), the second goby 4c can have a flat side wall.

  Further, in the roof material as shown in FIG. 17, for example, in the roof material as shown in FIG. 17, the long edge portions 1a and 1b of the roof material body 1 are formed over the entire length in the longitudinal direction. Since the raised portion 11 ′ is also formed in the lower joint 4, the rigidity of the portion is increased, and a large force is required for folding the standing locking piece 4 d (it is difficult to fold). When such a roof material is used, it is preferable to provide, for example, a notch or a slit so as to exclude the portion 12 where the rigidity is increased.

  FIG. 18 is a view partially showing an example in which a roof of a building structure is lifted up using a plurality of fitting-type roof materials according to the present invention (the illustration of the waterproof packing is omitted).

  The roofing material is placed on the ground board with secondary waterproof paper asphalt roofing, allocated according to the working width of the roofing material, inked, and attached to the eaves with a water drainer (not shown). 1) The first and the second roof materials are arranged from the eaves of the roof “Keraba” in line with the ink, and the fixing tongue 3d of the lower goby 3 of the roof material and the tongue 4e of the lower joint 4 are arranged. Screw each screw at a predetermined interval, or hit a nail or the like to fix it to the base plate, purlin or the like.

  Next, the first and second roof materials (other adjacent roof materials) are placed on the water side (ridge side) of the already fixed first and first roof materials to connect the roof materials together. . To connect the first and second roof materials to the first and second roof materials, the upper joint 5 of the first and second roof materials is overlapped with the lower joint 4 of the first and first roof materials. To match, the third gob 5b of the upper joint 5 is fitted to the first gob 4b of the lower joint 4, and the fourth gob 5c of the upper joint 5 is fitted to the second gob 4c of the lower joint 4. Just do it. At this time, the standing locking piece 4d of the lower joint 4 of the first row / first stage roof material and the hanging locking piece 5d of the upper joint 5 of the first row / second stage roof material are folded back so as to be overlapped. Thus, the both roof materials are linked so as not to be pulled out by the upright locking pieces 4d and the hanging locking pieces 5d. The roof material in the first row and the second row is also fixed to the base plate, the main building or the like by screwing screws into the tongue pieces 3d of the lower goby 3 or the tongue pieces 4e of the lower joint 4 or driving nails or the like.

  The above connection work is repeated until the roof ridge is reached (connection in the direction between beams). When the connection work in the first row is completed, the roof material in the second row is arranged.

  To arrange the second row / first step roof material as the second row roof material, the upper row 2 of the second row / first step roof material is placed on the lower goze 3 of the already fixed first row / first step roof material. And the first goby 4b of the second row / first step roofing material is fitted to the fourth goby 5c of the first row / second step roofing material (connection in the girder direction).

  Next, the upper goby 2 of the second row / second level roof material is placed on the lower goze 3 of the first row / second level roof material, and the third gob 5b is the first of the second row / first level roof material. It is only necessary to fit the first goby 4b to the second goby 4c of the first row / second stage roof material, and the first row roof is also connected to the second row roof material. Repeat until you reach the roof ridge, just like the wood.

  For the roof material in the third row and thereafter, it is only necessary to connect in the beam-to-beam direction and the girder direction in the same manner as the roof material in the second row, and this will raise the roof of the building structure.

  In the present invention, the standing locking piece 4d of the lower joint 4 and the hanging locking piece 5d of the upper joint are shown as rectangular examples in the present invention. There is no limit.

  In addition, as the lower joint 4, as described as an example that is connected to the short edge 1 e of the roof material body 1 through the step d, the lower joint 4 and the roof material body 1, as shown in FIG. They may be connected without passing through the step d (the same state) (the broken line in FIG. 19 indicates the boundary between the lower joint 4 and the roof material body 1).

  20 is an external perspective view showing another embodiment of the fitting roof material according to the present invention, and FIGS. 21A and 21B show the lower joint of the fitting roof material shown in FIG. It is the external appearance perspective view shown changing the angle. 20 and 21, elements similar to those in the above-described embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In this embodiment, the upright locking piece 4d is a folded locking piece 4d ′ folded so that one surface (the surface facing upward in the state before being folded) faces the outer surface of the plate-like body 4a. . The folded locking piece 4d 'is folded from the beginning. The folded back locking piece 4d ′ is preferably folded back at an angle of 180 °.

  22 (a) and 22 (b) are external perspective views showing a modified example in which a waterproof packing is provided on the lower joint of the fitting-type roofing material shown in FIGS. 20 and 21, and FIG. 23 is a fitting view shown in FIG. It is a figure which shows the cross section in the connection part of a combined roof material.

  In this modified example, the lower joint 4 includes, from the outer side surface of the first goby 4b, the top of the first goby 4b, the inner side surface of the first goby 4b, the first goby 4b and the folded locking piece 4d ′. , On the upper surface (the other surface) of the folded back locking piece 4d ′, on the top surface of the folded back locking piece 4d ′ and the inner side surface of the second goby 4c, on the inner side surface of the second goby 4c, A single waterproof packing 13 that extends continuously is provided in a region extending from the top of the goby 4c, the outer side surface of the second goby 4c, and the tongue piece 4e. The waterproof packing 13 may be provided only in a region from the top 4b of the first goby 4b to the top of the second goby 4c through the upper surface of the folded locking piece 4d '(not shown). ).

  As the waterproof packing 13, for example, an EP sealer made of EPDM rubber foam which can be elastically deformed when a compressive force is applied can be used. The thickness, length, and width can be appropriately changed according to the size of the roof plate material, and can be attached using a double-sided tape or an adhesive.

  When the connection of the roofing material is completed, the waterproof packing 13 is located between the lower joint 4 and the upper joint 5 as shown in FIG. Intrusion can be reliably blocked.

  Further, since the waterproof packing 13 is provided on the upper surface of the folding engagement piece 4d ', the folding process of the portion that becomes the folding engagement piece 4d' is completed once, so that the standing engagement piece 4d is formed by bending to stand up. The manufacturing process can be shortened as compared with the case where the upright locking piece 4d is bent again to an angle of 180 ° after the prevention packing 10 is stuck inside the locking piece 4d (for example, FIG. 14). In this embodiment as well, prevention packings may be provided on both the upper and lower surfaces of the folded back locking piece 4d '.

  FIG. 24: shows the fitting type roof material of other embodiment of this invention, (a) is a perspective view, (b) is DD sectional drawing. In this fitting type roofing material, the fixing tongue 3d of the lower goby 3, the tongue 4e provided at the lower end of the second goby 4c and connected to the fixing tongue 3d, and the lower end of the fourth goby 5c are provided. The tongue piece 5e connected to the fixing tongue piece 3d is formed with a folded portion (humming) f in which the width direction end portion (free end) is continuously folded upward from the water upper side to the water lower side. In this way, even when water invades from the gap formed between the adjacent roofing materials by providing the folded portions f extending from the water upper side to the water lower side on the tongue pieces 3d, 4e, 5e, The folded portion f functions as a water dam and the water flows along the folded portion f and is discharged from the eaves. In addition, such a folding | turning part f can be similarly provided not only in the roof material of this embodiment but in the other roof material shown previously.

  Further, in the present embodiment, the folded back locking piece 4d ′ is formed with a tightly bent portion h that is crushed at the end in the width direction and brought into close contact with the outer surface of the plate-like body 4a. Water intrusion performance can be improved by reducing or suppressing water intrusion from between the end of the folded back locking piece 4d 'and the plate-like body 4a. In addition, the contact | adherence bending part h can be similarly provided not only in the roof material of this embodiment but in the other roof material shown previously.

  FIG. 25 is a cross-sectional view of an essential part showing a cross section of the roof material according to another embodiment of the present invention at the same position as the E part of FIG. In this fitting type roofing material, when the waterproof packing 13 is affixed to the upper surface of the folding back locking piece 4d 'as shown in FIG. 22, the folding roof material between the folding back locking piece 4d' and the first and second goby 4b, 4c is used. A slack portion (convex portion) 13a is formed in each recess. By forming the slack portion 13a in the recess between the folded back locking piece 4d ′ and the first goby 4b in this way, the gap between the waterproof packing 13 and the plate-like body 4a can be eliminated in the recess. The water stop performance can be improved.

  According to the present invention, since roof materials can be easily and reliably joined together while maintaining high waterproofness, the roof material can be scaled, and the molding of the roof material in the field becomes unnecessary. .

  Moreover, according to this invention, it is possible to comprise a roofing material with the single member which does not require the extra member for joining roofing materials, and an efficient hoisting operation | work is realizable.
