Description

The present invention relates to a mating roofing material (including both vertical roofing and horizontal roofing) widely used in the roofs of general houses, offices, condominiums, welfare facilities, resort facilities, etc., and a method for connecting the roofing materials. Is.

In general, for a vertical roof, it is common to use a long, narrow roofing material whose main body is long in the beam-to-beam direction (direction from the eaves to the ridge) and short in the girder direction (direction along the eaves). The entire roof is roofed by repeating the work of connecting the roofing materials in the girder direction after finishing the connection between the roofing materials in the beam-to-beam direction.

On the other hand, for a horizontal roof, the main body of the roofing material is usually long in the girder direction and short in the beam-to-beam direction, and a wide roofing material is usually used. The entire roof is roofed by repeatedly connecting the roofing materials in the direction.

Although there are differences in the roofing method of this type of roofing material, all of them are continuously produced by rolling molding a long coil, especially for vertical roofing. The roofing material is often made of 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, in the case of a roofing material for vertical roofing made of a single piece, when roofing is done in a house located in the city center, it is difficult to bring it in because the road is narrow, or it is under construction. Because it is difficult to secure a work space (surrounding open space, etc.) to be used for the roof, its use may be restricted, and it has been difficult to expand demand.

As a prior art for solving such conventional problems, for example, in Patent Document 1, a curved metal roof plate is formed in a substantially semi-cylindrical shape on a tile rod provided on a roof tile. A front edge part where a reinforcing material with a part is fitted, tapered to the back side except for the left and right ends and folded back to form a male part for locking, an S-shaped flattened folded female part, multiple pieces The ridge for rain return and the trailing edge folded back to the surface side are sequentially formed in the lateral direction and in the direction of the trailing edge, and the trailing edge is bent symmetrically and spreads laterally to the upper end. It is composed of left and right rising parts that form curved parts, and is located between the tile bars, from the eaves of the roof to the ridge, and the male part of the front edge of the metal roof plate is folded back from the other roof plate. The left and right rising parts are inserted into the parts and engaged, and the left and right rising parts are contacted and covered from the lower ends of the left and right reinforcing materials fitted to the roof tiles to the curved parts. Multiple wraps are laid while connecting the boards, and the tile rods are abutted and covered with the reinforcing material in the longitudinal direction from the lower end of the reinforcing material to the curved portion, for each rising portion of the metal roof plate. A method of roofing metal roof tiles, in which the roof tiles are sequentially covered with materials, has been proposed.

Further, in Patent Document 2, a vertically-roofed roof plate having engaging portions formed on the left and right side edges and having a standard length in the flow direction is connected in the flow direction via a joint member, and the vertically-roofed roof plate is connected in the left-right direction. For a vertically-roofed roof in which a drainage member having a flowing water space is arranged below the portion, the joint member is arranged inside the waste plate member and the waste plate member whose side ends face the flowing water space of the drainage member. It shall be provided with a water blocking member having at least one groove formed therein, the eaves side end of the vertical roofing plate laid on the ridge side of the joint member, and the vertical roofing plate laid on the eaves side as well. Folded lower parts are formed at the ridge side ends of the ridge, and these folded lower parts are inserted into the grooves of the water blocking member to connect the vertically-roofed roof plates adjacent to each other in the flow direction. Further, in Patent Document 3, a connecting structure is provided, and in Patent Document 3, a face plate portion is provided in the central portion, and an inner rising portion is provided on the left and right side edges thereof. The vertical roofing exterior material for construction and the outer layer structure of the building are provided with an engaging portion engaging portion that elastically engages with the holding member at either one or both of the upper end and the middle of the outer rising portion. Proposed.

5) The lower goby is provided with a tongue piece for fixing, the lower end of the second goby is provided with a tongue piece connected to the tongue piece for fixing on the water side, and the lower end of the fourth goby is provided with the tongue piece. A tongue piece connected to the fixing tongue piece on the underwater side is provided, and the fixing tongue piece, the second goby tongue piece and the fourth goby tongue piece are continuous from the water upper side to the water lower side. Therefore, a folded portion is formed in which the end portion in the width direction is folded upward.
6) The upright locking piece is a folded locking piece that is folded back so that one surface faces the outer surface of the plate-like body, and the lower joint is the lower joint from at least the top of the first goby. It is preferable to have a continuous waterproof packing in the region from the other surface of the folded lock piece to at least the top of the second goby as a specific means for solving the problem.

Further, the present invention relates to a method for connecting a fitting roofing material having the above configuration.
The upper joint provided on the short edge portion of the roofing material main body is superposed on the short edge portion of another roofing material arranged adjacent to the underwater side, and the third goby and the fourth goby are placed under the water. The hanging locking piece is folded back while being fitted to the upper and lower gobies of other roofing materials arranged adjacent to the side, and then the lower joint provided on the short edge of the roofing material main body is attached to the water upper side. The short edges of the other roofing materials to be arranged adjacent to each other are overlapped with each other, and the upper and lower gobies of the other roofing materials to be arranged adjacent to each other on the water side are fitted to the first goby and the second goby, and the standing upright. It is a fitting type roofing material connecting method characterized in that roofing materials are connected to each other in the beam-to-beam direction by folding back the locking pieces.

According to the present invention, when the roofing materials are connected in the beam-to-beam direction, the upright locking piece of the lower joint and the hanging locking piece of the upper joint are folded back, so that the roofs are arranged adjacent to each other on the underwater side and the upper side of the water. Since it is linked with the material, the roofing materials can be reliably connected to each other without requiring an extra member. In particular, by folding back the hanging locking piece, the short edge portion of the roofing material body is in a state of being double-layered (bent by 180 °) to increase the rigidity, and it is possible to avoid shape deformation such as the roofing material bulging in a convex shape.

Further, according to the present invention, by providing the waterproof packings on both ends and the lower ends in the width direction of the hanging locking piece or the entire surface thereof, the plate thickness and mechanical properties of the roofing material are changed, or when molding is performed. Even if the gap size fluctuates due to dimensional variation (shape change 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 the intrusion of rainwater. It can be avoided and can be standardized.

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 at least the top of the second goby through the plate-like body, or the upper joint is provided with a waterproof packing. The region from the top of the inner wall of the third goby to the widthwise end of the first plate and the other widthwise end of the first plate from the top of the inner wall of the fourth goby. Since waterproof packings are provided in each of the areas up to the above, it is possible to block the inflow of rainwater from the overlapping portion of the roofing materials even in this case.

Further, according to the present invention, the hanging locking piece has a length equal to or longer than that of the standing locking piece, so that the linking strength of the roofing material can be increased and the roofing material can be waterproofed. It is possible to expand the packing installation range (expand the seal area).

Further, according to the present invention, since the angle formed by the standing locking piece with the outer surface of the plate-like body is set to more than 0 ° to 45 °, a large force is required when connecting the roofing materials to each other. It is possible to fold up the standing locking piece without any trouble, which simplifies the roofing work. In addition, when the standing locking piece is folded back (180 ° bending) from the beginning, 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 by the outer surface of the plate-like body is preferably 5 to 45 °.

When the hanging locking piece is provided, the waterproof packing is attached and then bent, so that the waterproof packing does not wrinkle or fluctuate in thickness. Further, by bending the hanging locking piece after attaching the waterproof packing, the angle formed by the hanging locking piece with the back surface of the first plate-like body is set to more than 0 ° to 45 °, preferably 5 to 45 °. When joining the roofing materials, the hanging locking pieces can be tilted down without applying a large force, and the roof of the building structure can be efficiently roofed.

Further, in the case of a roofing material having a waterproof packing on the upper surface of the folded-back locking piece, since the bending step of the portion to be the folded-back locking piece can be performed only once, the standing locking piece is formed by bending and the standing locking piece 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.

Further, according to the method of connecting the fitting type roofing material of the present invention, the upper joint provided on the short edge portion of the roofing material main body is superposed on the short edge portion of another roofing material arranged adjacent to the water lowering side. The third goby and the fourth goby are fitted to the upper and lower gobies of other roofing materials 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 is used. The short edge of the other roofing material that is adjacent to the lower joint provided on the water side is overlapped with the first goby, the second goby, and the other roofing material that is adjacent to the water side. Since the roofing materials are connected in the direction between the beams by fitting the upper and lower gobies and folding back the standing locking pieces, the connection work between the roofing materials is relatively easy and extra members are required. There is nothing to do.

By attaching waterproof packings 6, 7, and 8 to the area from the first plate-shaped body 5a to the other end in the width direction, respectively, when the connection of the roofing material is completed, The waterproof packings 6, 7, and 8 are located in a state where a compressive force is applied between the lower joint 4 and the upper joint 5, and the intrusion of rainwater from that portion can be reliably blocked. it can. FIG. 10 shows the positional relationship between the waterproof packing 6, the lower joint 4, and the upper joint 5.

As the waterproof packings 6 to 8, for example, an EPDM rubber foam Ept sealer that can be elastically deformed when a compressive force is applied can be used. The thickness, length, and width can be changed as appropriate according to the size of the roof plate material, and may be attached using double-sided tape or an adhesive.

As the waterproof packing 6, as shown in FIGS. 11A to 11C, the waterproof packing 6 can be attached to the entire surface of the hanging locking piece 5d. According to the waterproof packing 6, as shown in FIG. 12 showing a cross section in a connected state, the sealing area is expanded, so that the waterproof property at the overlapped portion is further enhanced. The waterproof packing 6 arranged on the hanging locking piece 5d is preferably a wide size protruding from both ends and the lower end in the width direction of the hanging locking piece 5d by about 2 to 3 mm. The leak path formed between the two can be reliably blocked.

13 (a) (b) and 14 (a) (b) show from at least the top of the first goby 4b of the lower joint 4 to at least the top of the second goby 4c through the plate-like body 4a. An example in which waterproof packings 9 and 10 are attached to the area is shown.

Also in this case, when the connection of the roofing material is completed, the waterproof packings 9 and 10 are located between the lower joint 4 and the upper joint 5 as shown in FIGS. 15A and 15B. Therefore, the intrusion of rainwater from that part can be reliably blocked.

The waterproof packings 6 to 10 have been shown in the case where they are provided in either the lower joint 4 or the upper joint 5, but it is also possible to attach the preventive packing to both the lower joint 4 and the upper joint 5. There is no limitation on.

The second goby 4c constituting the lower joint 4 has a tongue piece 4e connected to the fixing tongue piece 3d of the lower goby 3 via a step d3 at the lower end thereof (similar to the fixing tongue piece 3d). The rigidity of the second goby 4c itself becomes relatively high, and depending on its size, when the fourth goby 5c of the upper joint 5 of the other roofing material arranged adjacently is fitted, There is also concern that the waterproof packing 8 attached to the inner wall of the fourth goby 5c may be peeled off. Therefore, the side wall of the second goby 4c can be flat as shown in FIGS. 16A and 16B.

Further, in the case of a roofing material in which a raised portion 11 is formed on the long edge portions 1a and 1b of the roofing material main body 1 over the entire length in the longitudinal direction, for example, as shown in FIG. 17, when the roofing material is formed by roll forming, the roofing material is formed. Since the raised portion 11'is also formed in the lower joint 4, the rigidity of that portion is increased, and a large force is required to fold back the standing locking piece 4d (it becomes difficult to fold back). When such a roofing material is used, it is preferable to provide, for example, a notch or a slit that excludes the portion 12 having high rigidity.

FIG. 18 is a diagram partially showing an example of a case where a plurality of fitting type roofing materials according to the present invention are used to roof a building structure (the waterproof packing is not shown).

The roofing materials in the first and second stages are also fixed to the field board, purlin, etc. by screwing screws into the tongue piece 3d for fixing the lower goby 3 and the tongue piece 4e of the lower joint 4, or by hitting nails or the like.

The above connection work is repeated until the roof ridge is reached (connection in the beam-to-beam direction), and when the connection work in the first row is completed, the roofing material in the second row is placed.

To place the second row / first tier roofing material as the second row roofing material, the second row / first tier roofing material upper haze 2 is placed on the already fixed first row / first tier roofing material lower haze 3. And the first brace 4b of the second row / first stage roofing material are fitted to the fourth brace 5c of the first row / second stage roofing material (connection in the girder direction).

Next, the upper goby 2 of the second row / second stage roofing material is placed in the lower goby 3 of the first row / second stage roofing material, and the third goby 5b is placed in the first of the second row / first stage roofing material. The first goby 4b may be fitted to the goby 4b and the second goby 4c of the first and second row roofing materials, respectively, and the second row roofing material may be connected to the first row roof. Repeat until you reach the roof ridge, just like the wood.

For the roofing materials in the third and subsequent rows, the roofing materials of the building structure can be roofed by connecting them in the beam-to-beam direction and girder direction in the same procedure as the roofing materials in the second row.

In the present invention, the upright locking piece 4d of the lower joint 4 and the hanging locking piece 5d of the upper joint are both shown as examples of rectangular shapes, but the shapes thereof can be changed as appropriate and are shown in the drawings. There is no limitation.
