Description

  The present invention relates to a square bar-shaped synthetic resin tile rail used by being attached to a tile base material of a roof portion of a building in a lateral direction perpendicular to the inclination direction of the roof.

  When attaching tiles to the roof of a building, in general, on the rafters that are slanted from the roof ridge toward the eaves, for example, a field plate is struck along the direction of the inclination, and on the top surface of the field plate. A protective sheet is laid and a tile base material is provided. Then, by placing fixed members such as fixed nails in the horizontal direction perpendicular to the roof inclination direction on the upper surface of the tile base material, a plurality of parallel bars of square bar-like tiles are installed and supported by the tiles installed after that. In this way, the roof tiles having the hooks on the upper surface are attached while being hooked on the upper side of the roof bar so as not to slide down. As a result, a roof covered with tiles is formed.

  Here, wooden tile rails formed in the shape of rectangular bars with a rectangular cross section have been conventionally used as tile rails to lock the tiles on the roof, and these tile rails penetrate the field plate. Thus, by driving the fixing member up to the rafters arranged at a predetermined arrangement pitch, the tile base material is firmly fixed. In addition, when the rainwater enters the backside of the installed tiles or condensation water is generated, the tiles are installed at vertical pitches arranged at a predetermined pitch so that they can be quickly discharged and discharged in the direction of the roof inclination. It is attached while being sandwiched between the base material and a drainage gap is formed between the roof bar and the tile base material.

  On the other hand, wooden roof tiles are made of a material that is easily corroded if they are kept in contact with rainwater, dew condensation water, etc. for a long time. In some cases, a synthetic resin tile frame is used as a tile frame having excellent corrosion resistance instead of a wooden tile frame. In order to form a synthetic resin roof rail in the shape of a long square bar, it is desirable to continuously form a linear shape by extrusion molding according to the required length, and the synthetic resin made by such extrusion molding However, it is difficult to form deep irregularities on the peripheral surface by extrusion molding, so a concave part large enough to form a gap for draining is formed. There is a drawback that sometimes it cannot be provided as a unit.

On the other hand, for example, a tile rail is formed by injection molding using a mold, and a concave portion large enough to form a gap for draining can be simultaneously formed at the time of molding. Are also known (see, for example, Patent Documents 1 and 2). In addition, with these synthetic resin roof tiles made by injection molding, if it is attempted to form tile roof bars of different lengths according to the required length, it becomes necessary to form a mold each time, resulting in poor production efficiency. For this reason, the tiles are formed in a certain moderate length in consideration of ease of handling, and connecting protrusions and recesses are provided at both ends so that they are continuously integrated in the longitudinal direction or cut at appropriate positions. However, a method of adding and using is adopted.

  In addition, according to the conventional synthetic resin roof tile, when it is fixed to the tile base material, for example, 800 mm, 910 mm, 1000 mm, etc. in order to facilitate the driving work into the rafter covered with the tile base material. In a building designed in module units with the length of the base as the reference length, the fixed member is driven into the top surface of the roof tile in accordance with the position of the rafters installed in the arrangement span based on these reference lengths. After marking the position clearly and aligning one marking with the rafter placement position, the fixing member can be driven into the rafter sequentially using the marking as a guide to fix the roof rail. A device has been devised to make it smooth.

  However, according to the conventional synthetic resin roof tiles with such markings, when being attached to the tile base material while being continuously integrated in the longitudinal direction via the projections and recesses for connection at both ends. For example, when the end material protruding from the side edge of the tile base material is cut and used as a tile rail in the next row, it is necessary to re-align the marking to the rafter position. Depending on the cutting position of the crosspieces and the location of the rafters at the side edges, waste materials with a length equivalent to the rafter placement span will occur at the maximum, resulting in material loss and industrial waste generation. become.

  The present invention has been made by paying attention to such a conventional problem, and has a concave portion large enough to form a gap for draining water, and can be used by being connected in the longitudinal direction. Another object of the present invention is to provide a synthetic resin roof tile that makes it possible to easily and smoothly drive a fixing member into a rafter using a marking as a guide while suppressing generation of waste materials.

The roof tile 12 having a hooking claw on the upper part of the back surface is attached to the roof 10 while being supported so as not to slide down by hooking the hooking claw on the upper side of the roof tile 10. As a result, a roof portion covered with the tiles 12 is formed.

  As described above, the tile rail 10 according to the present embodiment is a square bar-like shape that is used by being attached to the tile base material 13 of the roof portion 11 of the building in the lateral direction perpendicular to the inclination direction of the roof in order to lock the tile 12. As shown in FIGS. 2 (a) to 2 (d), rafters on which the planar protrusions 17 receive the roof tile base material 13 on the lower surface 10 a serving as a mounting surface to the roof tile base material 13. 14 is provided at an equally divided pitch, and a spacing portion 18 between adjacent planar protrusions 17 forms a water passage in the inclination direction of the roof. On the upper surface 10b, a plurality of different types of markings 19a to 19e (five types in the present embodiment) that clearly indicate the driving position of the fixing member are provided on the portion corresponding to the planar protrusions 17 (see FIG. 1A). ) Of the same type A plurality of different types of markings 19a to 19e are arranged in the same order in the longitudinal direction so that the markings 19a to 19e are repeated at every arrangement pitch of the rafters 14, and one end face in the longitudinal direction is connected to one end face A convex portion 20 is provided, and a connecting concave portion 21 into which the connecting convex portion 20 is fitted and locked is provided on the other end surface.

  Moreover, according to this embodiment, the anti-slip pattern 22 for preventing the sliding of the tile 12 to be engaged is provided on the upper surface 10 b of the roof tile 10.

  According to the present embodiment, the roof rail 10 is preferably a synthetic resin molded product by injection molding, for example, a gold that is processed and formed into a predetermined shape and length along the shape of the roof rail 10 to be formed. By injecting and curing the thermoplastic resin that has been heated and flowed into the mold, it is easily integrally formed into a shape including the planar protrusions 17, the anti-slip pattern 22, the connecting convex part 20, the connecting concave part 21, and the like. .

  The roof tile 10 has a rectangular cross section having a width of about 25 to 40 mm and a thickness of about 13 to 21 mm, for example, and the arrangement pitch of the rafters 14 is 455 mm (910 mm) in consideration of the weight of snow in a cold region, for example. ½ module in the case of 1 module), the length is 4 times the arrangement pitch plus the length of the connecting projection 20.

  As shown in FIGS. 3A to 3D, the planar protrusion 17 provided on the lower surface 10a of the roof rail 10 projects the ground contact surface 17a at a height of about 1 to 6 mm, for example, A plurality of continuous arrangements are provided in the longitudinal direction of the roof tile 10 at a central arrangement pitch that is 1/5 of the arrangement pitch of the rafters 14. In the present embodiment, the planar protrusion 17 has a hexagonal planar shape, and the adjacent planar protrusions are arranged by arranging a pair of opposing sides along both side edges of the roof tile 10. In the space 17, a space portion 18 having a drum-shaped planar shape is provided across the roof tile 10. When the roof rail 10 is attached to the tile base material 13 with the ground contact surface 17a of the planar protrusion 17 in close contact, a considerable height is provided between the lower surface 10a of the roof rail 10 and the tile base material 13 at the interval portion 18. As a result, the rainwater and the like that have entered the back side of the tile 12 can be quickly discharged and discharged.

  In this embodiment, the markings 19a to 19e provided on the upper surface 10b of the roof rail 10 are formed by, for example, extending the central narrow groove 23 along the central narrow groove 23 that extends in the longitudinal direction through the center of the roof rail 10. By branching into a desired shape or crossing the other narrow groove with the central narrow groove 23, it is preferably applied as five different markings 19a to 19e. In other words, the first marking 19a has a shape branched to draw a rhombus, for example, and the second marking 19b has a shape branched to draw a square, for example. Further, the third marking 19c has a shape branched, for example, to draw a triangle, and the fourth marking 19d has a shape branched, for example, to draw a circle. Further, the fifth marking 19d is a cross-shaped mark, for example, by providing a vertical narrow groove 24 perpendicularly intersecting the central narrow groove 23.

  Further, these five kinds of different markings 19a to 19e are arranged at the center arrangement pitch of the rafters 14 so as to fit in the area overlapping the area where the planar projections 17 of the lower surface 10a of the roof tile 10 are provided. And the same type of markings are arranged in the same order in the longitudinal direction of the roof rail 10 so that the same type of marking is repeated at every arrangement pitch of the rafters 14. Thus, for example, after positioning any one of the markings 19a to 19e to the arrangement position of the rafter 14 and driving the fixing member into the rafter 14 through the planar protrusion 17, the same kind of markings 19a to 19e are guided. However, it is possible to smoothly fix the roof tile 10 by driving the fixing members sequentially into the rafters 14 without performing separate positioning.

  According to the present embodiment, the anti-slip pattern 22 applied to the upper surface 10b of the roof tile 10 is provided with the ridges 25 having a height of about 0.3 to 3 mm, for example, on both sides of the central narrow groove 23. The X shape is arranged and formed so as to be a pattern connected in the longitudinal direction.

It becomes possible to improve.

  The connecting convex portion 20 provided on one end face in the longitudinal direction of the roof tile 10 is an overhanging portion that borders the main body portion of the roof tile 10 and protrudes with a smaller cross section than the main body portion. Since the portion is formed in a bifurcated portion, the bifurcated portion can be elastically deformed in the thickness direction. Further, a connection locking protrusion 26 is provided on the lower surface of the distal end of the connection protrusion 20 so as to protrude downward.

  The connecting concave portion 21 provided on the other end surface in the longitudinal direction of the roof rail 10 is a concave portion for fitting the connecting convex portion 20 opened to the end surface so as to be depressed, and has a size corresponding to the connecting convex portion 20. Has pod depth. A connection locking hole 27 is formed in the lower surface of the deep portion of the connection recess 21. A pair of adjacent protrusions 20 are inserted and arranged in the connection recess 21 while elastically deforming the forked portion on the tip side of the connection protrusion 20, and the connection locking protrusion 26 is detachably locked to the connection locking hole 27 in a snap form. The roof tile 10 to be connected is easily connected and locked in the longitudinal direction and joined and integrated.

  And, according to the roof tile 10 of the present embodiment having the above-described configuration, it is provided with the concave portion (interval portion) 18 large enough to form a drainage gap and easily in the longitudinal direction. It can be used in a connected manner, and the operation of driving the fixing member into the rafter 14 using the markings 19a to 19e as a guide can be performed easily and smoothly while suppressing the generation of waste materials.

  That is, as described above, the roof tile 10 of the present embodiment can be easily formed with the planar protrusions 17 having a considerable height at intervals, preferably by injection molding. The gap can be easily formed, and can be easily connected in the longitudinal direction via the connecting convex portion 20 and the connecting concave portion 21. Further, any one of the five types of markings 19a to 19e is selected and aligned with the arrangement position of the rafters 14, and the tiles 10 are sequentially attached to the rafters 14 using the same types of markings 19a to 19e as a guide. For example, when the edge material of the roof tile 10 that protrudes from the side edge of the roof tile base material 13 is cut and used as the next row roof rail 10, the edge can be fixed smoothly. Since it becomes possible to perform the fixing work of the next row of tiles 10 while aligning using the arbitrary markings 19a to 19e closest to the edge of the material, the length of the waste material is the marking 19a to the maximum. Since it becomes the length between 19e (1/5 of the arrangement | positioning span of the rafter 14), it becomes possible to suppress effectively the loss of material and generation | occurrence | production of industrial waste.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the markings applied to the upper surface of the roof rail need not necessarily be five types, and may be two to four types, or six or more types. Moreover, the planar protrusion provided on the lower surface of each marking or roof tile may have a shape other than those described above, and the marking does not necessarily have to be drawn using a narrow groove. Further, it is not always necessary to provide a non-slip pattern on the upper surface of the roof tile, and it may be formed by a molding method other than injection molding.
