Description

  The present invention relates to a roofing material rail that is excellent in workability and has a performance higher than that of an existing roofing material.

  As shown in FIG. 17, the conventional roofing material rail is formed with a pair of fitted portions 81a facing inward from both sides in the width direction of the upper part of the main body to form a gutter 81 that is continuous in the direction perpendicular to the paper surface. A gutter 81 is formed by bending a single sheet metal. The gutter 81 includes a gutter 81, a ceiling material in which a locking rising side portion 84 having a locking bent piece 84a that locks the fitted portion 81a from both sides in the width direction of the ceiling main plate 83, and a roof main plate 86. A roof material in which a fitting side portion 87 to be fitted to the fitted portion 81a of the gutter 81 is formed on both sides in the width direction, and a connecting raised portion 88 is formed on the outer side from the lower ends of the fitting side portions 87; A vertical roof is constituted by the connecting member 89 that connects the upper end portions of the two rising portions 88 for connecting the adjacent roof materials (Patent Document 1).

  Further, as other roof material rails, as shown in FIG. 18, a backup member 92 as a space forming and supporting member formed by forming an air layer 95 between the inner base material 91 and the outer base material 93, There is known a suspension 94 that is positioned and fixed at a predetermined interval in the eaves-ridge direction on the backup member 92 (Patent Document 2). In the structure of the roof in Patent Document 2, as shown in the figure, an outer base material 93 is disposed between the backup members 92 on the inner base material 91 in the eaves-ridge direction, and both ends in the row direction are suspended. An air layer 95 that is supported by the child 94 and communicates with the inner base material 91 in the eaves side direction is formed.

  However, in the roofing material rail of Patent Document 1, although the waterproof performance is enhanced by the fitting side portion 87 and the lower side of the gutter 81 is fixed by a fixing screw, the fixing member is supported by the sheet metal. Since the strength is weak, it is only a function as a roofing material, and the development of functions beyond the roofing material is impossible.

  Moreover, in the roofing material rail of Patent Document 2, although the waterproof performance is improved by the water leakage prevention plate 99 and the lower side of the backup member 92 is fixed by a fixing screw, the water leakage prevention plate 99 is Separate parts are required, and the backup member 92 disposed in the lower part and the hanging member 94 disposed in the upper part are also separate parts. Therefore, the number of members increases and the workability is accordingly reduced.

  In view of the above, the present invention not only fixes the roofing material but also can fix any member such as a solar cell module installed on the roof, reducing the number of parts and improving the workability. An object of the present invention is to provide a roofing rail that can be made to operate.

  The roofing material rail according to the present invention includes: a rail-shaped receiving rail that allows a fixing member to be fastened in a predetermined position and extends directly from the bottom in the flow direction of the roof, and a building structural member disposed below the receiving rail. And a fin portion disposed on the left and right outer sides of the receiving portion and the receiving rail ”.

  Here, the “fixing member” is a member (for example, an extruded aluminum material, an L-shaped angle, C, etc.) that can fix any member (for example, a photovoltaic power generation module or a rooftop greening unit) installed on the roof. Channel). In addition, the “fin portion” is a wall-like shape that rises substantially vertically from the bottom of the roofing rail and is continuously formed in the longitudinal direction, and has a height substantially equal to the height of the receiving rail. desirable.

  According to the present invention, the fixing member can be fixed at a predetermined position, the rail-shaped receiving rail extending in the flow direction of the roof, the fixing portion disposed below the receiving rail and fixed to the building structure member, and fixing Part and a fin part arrange | positioned at the left-right outer side of a receiving rail. Thereby, since a fixing member can be fastened in a predetermined position by a rail-shaped receiving rail, it becomes possible to fix an arbitrary member installed on the roof via the fixing member.

  In addition, since the roofing rail has a structure in which the receiving rail stands directly from the bottom, the tensile force (for example, wind pressure load) applied to the roofing rail is directly applied to the fixing portion and is fixed by the fixing screw. The roofing rails that remain firmly will not be peeled off from the building structural members. Furthermore, with respect to the compressive load (for example, wind pressure load, snow load, etc.) applied from the fixing member, the force can be transmitted to the building structure member, and the roof material rail can be prevented from being broken.

  In addition, by providing a fixing portion on the lower side of the receiving rail, for example, the lower center of the receiving rail, when the roofing material rail is arranged on the roof, it becomes easier to align the center of the fixing portion with the position of the building structural member. By attaching the receiving rail to the position with a fixing screw, the fixing member can be more firmly attached to the building structure member.

  In addition, the fixing function of the fixing member and the receiving rail can be securely fixed to the building structure member such as the base plate with a single member, the number of parts can be reduced and the workability can be improved and executed without error. it can. In addition, since the fins arranged on the left and right outer sides of the receiving rail can be partitioned, for example, rainwater that has entered from the receiving rail side functions as a function between the receiving rail and the fin portion, to the left and right sides of the roofing rail In addition to preventing leakage, rainwater can flow to the eaves.

  The roofing material rail according to the present invention is characterized in that “the fixing portion is disposed at a position higher than the bottom portion”. Here, examples of the “fixed part arranged at a position higher than the bottom part” include, for example, “the fixed part is a ridge protruding upward from the bottom part”, “the fixed part is received at a position higher than the bottom part. Examples of the protrusions protruding in the left-right direction from the rising portion of the rails "can be given.

  According to the present invention, the fixed part is arranged at a position higher than the bottom part. The fixing portion is between the receiving rails that rise to the left and right, and the left and right sides of the fixing portion are provided with hooks using the space between the receiving rails. As a result, the fixing portion fixed by the fixing screw becomes higher than the bottom portion.For example, rainwater that has entered the receiving rail can be made difficult to enter from the fixing screw hole opened in the fixing portion. The rainwater can be made to flow to the eaves by the function of the bag made by the bottom part and the fixed part in the receiving rail. Examples of the shape of the fixed portion include a shape in which the bottom is raised, a shape in which the bottom is filled, and the like.

  The roofing material rail according to the present invention is as follows: “The receiving rail does not interfere with a fixing screw for fixing a predetermined bolt for fixing the fixing member to the receiving rail to the building structural member via the fixing portion. It is slidably supported on the ”.

  According to the present invention, the receiving rail supports the predetermined bolt for retaining the fixing member on the receiving rail so as to be slidable so as not to interfere with the fixing screw for fixing to the building structural member via the fixing portion. To do. As a result, when the predetermined bolt supported by the receiving rail is slid and the fixing member is held at the predetermined position, the head of the fixing screw protrudes above the fixing portion. Since it can be made slidable so as not to interfere with the fixing screw that protrudes to the upper part, it is possible to improve the workability.

  The roofing material rail according to the present invention is characterized in that "the positioning projections are further provided on both right and left ends".

  According to the present invention, the roofing rail further includes positioning protrusions on the left and right ends. Thereby, the end of the backup material (for example, a heat insulating material or a dent prevention material for the intermediate cover) installed on the back of the intermediate cover can be easily positioned by hitting the protrusions on the left and right ends of the roof material rail.

  The roofing material rail according to the present invention has an “engagement part that engages with an engaged part of an intermediate cover that covers between the roofing material rails arranged in parallel” in the fin part. It is characterized by being.

  According to the present invention, the fin portion of the roof material rail is formed with the engaging portion that engages with the engaged portion of the intermediate cover that covers between the roof material rails arranged in parallel. Thereby, the engaging part currently formed in the fin part of the roofing material rail can engage with the intermediate cover which comprises an engaged part, and the roofing material which covers between the roofing material rails arranged in parallel Can be formed as

  The roofing material rail according to the present invention is “the engaged portion of the intermediate cover is formed so as to be engageable with the engaging portion of the cover while covering at least the space between the left and right intermediate covers”. It is characterized by that. Here, the “inter-cover” has an engaging portion that has a substantially flat flat upper surface and protrudes obliquely downward from both ends.

  According to the present invention, the engaged portion of the intermediate cover is formed so as to be engageable with the engaging portion of the cover while covering at least the space between the left and right intermediate covers. As a result, the engaged portion of the intermediate cover is engaged with the cover while having the engaging portion when the fixing member is not fixed, or when the fixing member is not fixed, and the intermediate cover becomes a roof material, The design of the roofing rail can be improved.

  As described above, according to the present invention, not only the roofing material but also any member such as a solar cell module installed on the roof can be fixed, reducing the number of parts and improving the workability. The roofing rail which can be provided can be provided.

  As shown in FIGS. 1 to 3, the roof material rail 1 of the present embodiment enables the fixing member 8 to be fixed at a predetermined position, extends in the flow direction of the roof, and has a seated stat bolt 6 as a predetermined bolt. A receiving rail portion 1a having a rail-like fixing and fixing portion 10 that can be slidably supported and a projection 11 for preventing fall, and a base plate 71 (building structure member) that is disposed below the receiving rail portion 1a. The fixed part 12, the engaging part 13 as a fin part arrange | positioned at the left-right outer side of the receiving rail 1a, and the projection 14 for positioning arrange | positioned at both right-and-left both ends are provided. In addition, the stat bolt 6 with a seat is a member in which a welding bolt or a bolt is raised on a square plate-shaped washer, or a tap is cut on the square plate-shaped washer and the bolt is raised.

  More specifically, as shown in FIG. 3, the cross-sectional shape of the roofing material rail 1 has an opening (for example, a width in which a socket of an impact driver or a socket wrench can enter) at the upper part of the square at the center. A drop-preventing protrusion 11 having the same length as that of the fastening and fixing part 10 is provided on the inner side from a position slightly lower than the fastening and fixing part 10 on the upper side. The center of the quadrilateral bottom is raised, and there is a fixing portion 12 for fixing the fixing screw 5. On the right and left sides thereof, there are inner flanges 16 that use the height difference from the bottom to the rising fixing portion 12. The shape is developed on both the left and right sides of the quadrangle with the opening at the top at the center, but the left side is explained because of left-right symmetry, and the right side is axisymmetric with respect to the center of the square, so detailed explanation is omitted. . There is a bottom that extends to the left from the bottom of the quadrangle, and there are two rising parts. There is a first rising portion beyond the half-square width 15 and extends upward to a position slightly lower than the anchoring fixing portion 10, descending diagonally to the right, and extending upward. The engaging part 13 which returns to is comprised. There is a second rising portion beyond the outer flange portion 17 having a width about half that of the flange portion 15, and the positioning projection 14 extends upward to about one third of the engagement portion 13.

As shown in FIG. 2 and FIG. 3, the roofing material rail 1 is provided with a fixing portion 12 which can fix the fixing member 8 at a predetermined position by a seated stat bolt 6 and is arranged below the receiving rail 1a. The fixing screws 5 can be used to fix the building structural members (for example, the rafter 72, the C channel serving as the main building, the field board 71, etc.). Arbitrary members (for example, a photovoltaic power generation module 50, a rooftop greening unit, etc.) installed on the roof can be fixed by using the fixing member 8 with the seated stat bolt 6. When the fixing member 8 is installed, the spacer 7 is installed on the eaves side so that rain can easily pass through. Furthermore, by making the through hole 9 in the fixing member 8, for example, it is possible to connect the photovoltaic power generation modules.

  The fastening and fixing portion 10 and the drop-preventing projection 11 of the receiving rail 1a in the roofing material rail 1 are formed so that the seated stat bolt 6 can be slidably supported. Furthermore, when the seated stat bolt 6 is slid by the drop preventing projection 11, it can be slid without interfering with the head of the fixing screw 5. As a result, the seated stat bolt 6 slides to an arbitrary position by using the fastening fixing portion 10 and the drop preventing projection 11 of the receiving rail 1a, so that the fixing member 8 is moved to a predetermined position. It can be used to secure more firmly. In addition, by setting the size of the seat portion of the stud bolt 6 with a seat so as to hit the both side surfaces of the rail 1a, the fixing fixing portion 10 that is independent on the left and right spreads when a load is applied from the fixing member 8 side, It can be prevented from becoming narrow. Further, the size of the seated stat bolt 6 is set to M6 to M12, and can be appropriately changed with respect to use conditions.
