Description

  The present invention relates to a fixture for fixing equipment to a roof.

  When installing facilities such as solar power generation, solar water heaters, and air conditioner outdoor units on the roof of the building, the fixtures to fix these facilities are the mass of the facility installed on the roof and the area where it is installed. It is necessary to secure sufficient strength to withstand wind pressure and earthquakes. In general, these facilities are fixed by fixing a fixture for fixing the facility on the roof in advance and fixing the facility on the fixture. In order to secure a sufficient fixing strength, the fixing tool is fixed to a structure of the building such as a rafter through a building base plate with screws, nails, or bolts and nuts.

  For example, in Patent Document 1, as a support device for mounting a structure on a roof, a main plate in which a slide hole is formed, each side plate bent to the same side on both sides of the main plate, and one side of each side plate is bent outward. A structure comprising a fixed base, a moving part movable along a slide hole of a solid base, and a connecting part main body connected to the moving part is shown. A plurality of perforations and long holes are formed in the fixing base, and the fixing base can be firmly fixed to the rafters via the base plate, and the position of the connecting portion can be adjusted along the slide hole.

JP 2011-84984 A

  However, in the above support device, the end face of the main plate is partially thin at the slide hole formed in the fixed base, and thus the load bearing performance against wind load and snow load may be reduced. In order to avoid this, for example, there is a method of reducing the opening length of the slide hole.

  Further, in order to firmly fix the fixing base to the two rafters, when the fixing base is arranged so as to straddle the rafters, it is necessary to extend the fixing base at least more than the rafter interval. The manufacturing cost for the bending process increases.

  The present invention has been made in view of the above, and while securing the range of position adjustment of equipment installed on the roof of a building, securing of fixing strength and load bearing performance can be ensured, and manufacturing cost can be suppressed. Another object is to obtain a fixture that can also be used.

  In order to solve the above-described problems and achieve the object, the present invention is a fixture for fixing equipment to a roof, has a substantially rectangular shape in plan view, and a fixed base fixed to the roof; A wall portion that is erected on the fixed base portion so as to extend substantially parallel to the longitudinal direction of the fixed base portion, and that forms a groove that fits the head portion of the bolt and is formed over substantially the entire longitudinal direction of the fixed base portion; A bolt that is provided in substantially the entire area on the opposite side of the fixed base and is fitted in the groove so as to prevent the bolt fitted in the groove so that the shaft protrudes from the groove, and is fitted in the groove. A through hole that penetrates the shaft portion of the bolt and a connecting portion that connects the facility and the fixed base.

  ADVANTAGE OF THE INVENTION According to this invention, while ensuring the range of the position adjustment of the installation installed on the roof of a building, securing of fixed strength and load-bearing performance can be aimed at, and the cross-sectional shape to the longitudinal direction of a fixed base and a wall part By making these substantially the same, the production cost can be suppressed by using the extrusion method.

Embodiment 1 FIG.
FIG. 1 is an external perspective view showing a schematic configuration of the fixture according to the first embodiment of the present invention. FIG. 2 is a side view of the fixture shown in FIG. FIG. 3 is a perspective view showing a roof structure to which a fixture is attached. FIG. 4 is a perspective view showing a fixture attached to the roof structure shown in FIG.

  The fixing device 50 according to the first embodiment is fixed to a roof structure, and facilities (not shown) such as solar power generation, a solar water heater, an air conditioner outdoor unit, etc. are installed on the roof via the fixing device 50. Installed. In addition, the roof structure in which the facilities are installed includes, for example, a rafter 2, a pier 3, a field board 4, a roofing 5, and a roof material 6, as shown in FIG.

  As shown in FIG. 1 and the like, the fixture 50 includes a fixing base (fixing base) 7, a fixing bolt (fixing base fixing means) 8, a connecting part 9, and a connecting bolt (connecting part fixing means) 10. FIG. 5 is an external perspective view of the fixing base 7 provided in the fixing tool 50. FIG. 6A is a plan view of the fixing base 7 provided in the fixing tool 50. FIG. 6B is a front view of the fixing base 7 included in the fixing tool 50. FIG. 6C is a side view of the fixing base 7 provided in the fixing tool 50. The fixed base 7 has a substantially rectangular parallelepiped shape in plan view. The fixed base 7 is a plate member made of a metal such as an aluminum alloy.

  A long hole 73 is formed in at least one place on the fixing base 7. The fixing base 7 is fixed to the roof structure by fixing bolts 8 as fixing base fixing means through the long holes 73. For example, the fixing base 7 is fixed to the roof structure by screwing the fixing bolt 8 that penetrates the long hole 73 into the prepared hole formed in the field board 4 or the rafter 2. The fixing base fixing means may be other fixing means such as screws and nails.

  A wall 12 is erected on the fixed base 7 over the substantially entire area in the longitudinal direction with respect to the upper surface thereof. One set of wall portions 12 is provided so as to face each other, and a space 13 between the wall portions 12 constitutes a groove 13 into which a head 10a of a connecting bolt 10 as a connecting portion fixing means is fitted. A part of the fixed base 7 constitutes the bottom surface of the groove 13. That is, the wall portions 12 are connected by a part of the fixed base 7.

  The groove 13 is formed with a groove width slightly larger than the outer diameter of the head portion 10a. For example, a slight clearance of about 0.1 to 1 mm is provided between the head 10 a of the connecting bolt 10 and the groove 13. Therefore, the connecting bolt 10 is freely movable along the longitudinal direction of the fixing base 7 while being fitted in the groove 13.

  The groove 13 (wall portion 12) is formed at a height at which the shaft portion 10b of the connecting bolt protrudes with the head portion 10a of the connecting bolt 10 fitted. Moreover, although the wall part 12 is formed in the approximate center part with respect to the transversal direction of the fixed base 7, it may be formed by being shifted to one side in the transversal direction.

  A retaining portion 14 that is fitted in the groove 13 but prevents it from falling off in the direction of the shaft portion 10b is provided in a substantially entire region of the wall portion 12 opposite to the fixed base 7. Specifically, the retaining portion 14 is formed so as to narrow the groove width of the groove 13 to a groove width that is slightly larger than the outer diameter of the shaft portion 10 b of the connecting bolt 10. Thereby, it is possible to prevent the head 10a of the connecting bolt 10 from being caught in the retaining portion 14 and falling off in the direction of the shaft portion 10b. The fixed base 7 has substantially the same cross section in the longitudinal direction due to the configuration as described above.

  The connecting portion 9 has a structure in which a metal plate having a thickness of about 1 to 6 mm is bent, or a structure obtained by an extrusion method having the same cross section, and is made of a metal such as an aluminum alloy. As shown in FIGS. 1 and 2, the connecting portion 9 includes a through plate portion 93, a connecting portion 95, and an equipment mounting portion 91.

  The through plate portion 93 has a plate shape, and a through hole 94 is formed through which the shaft portion 10 b of the connecting bolt 10 fitted in the groove 13 is passed. At least one or more through holes 94 are formed. The connecting portion 9 is fixed to the fixing base 7 by the nut 11 being screwed into the shaft portion 10 b that is passed through the through hole 94 of the through plate portion 93. The through-plate portion 93 is fixed by the connecting bolt 10 and the nut 11, thereby being in a state substantially parallel to the fixing base 7.

  The connecting portion 95 is erected in a direction away from the fixed base 7 with respect to the end portion of the through plate portion 93. The equipment mounting portion 91 is provided so as to extend from the upper end of the connecting portion 95. That is, the through plate portion 93 and the equipment mounting portion 91 are connected via the connecting portion 95. Further, since the connecting portion 95 is erected with respect to the through plate portion 93, a step is provided between the through plate portion 93 and the equipment mounting portion 91.

  The equipment mounting portion 91 has a U-shaped cross section as shown in FIG. The facility mounting portion 91 is formed with a mounting hole 92 for mounting a facility installed on the roof. Equipment installed on the roof is attached to the fixture 50 by bolts, nuts, etc. using the attachment holes 92.

  Next, a method for attaching the fixture 50 to the roof structure will be described. First, a part of the roofing material 6 is removed from the roof structure, and the roofing 5 or the field plate 4 is exposed. The roofing material 6 may be fixed to the pier 3 with wood screws or nails.

  The fixing base 7 is temporarily placed so that the long hole 73 matches the position of the rafter 2. Then, the fixing base 7 and the rafter 2 are fixed by the fixing bolts 8 through the field plate 4 in at least one long hole 73 on both sides sandwiching the wall portion 12. The field board 4 is a compression plywood such as a wooden structural plywood or a particle board having a thickness of 9 mm or more. The rafter 2 is, for example, wood having a height of 20 mm or more, or metal.

  Here, the height from the upper surface of the fixing base 7 to the upper surface of the wall portion 12 is higher than the height of the head 8 a of the fixing bolt 8. Thereby, interference with components, such as the connection part 9 attached to the upper surface of the wall part 12, and the head 8a of the fixing bolt 8, can be avoided.

  The height from the bottom surface of the fixed base 7 to the top surface of the wall portion 12 is desirably 15 mm or less. For example, when the fixed base 7 is installed under the tile roof material, if the height is high, the fixed base 7 and the tile interfere with each other, and the gap between the eave side tile and the ridge side tile widens, and the waterproof function is lowered. There is a fear. Therefore, in order to ensure waterproofness, it is desirable that the height from the bottom surface of the fixed base 7 to the top surface of the wall portion 12 is 15 mm or less.

  FIG. 7A is a perspective view illustrating a state in which the connecting bolt 10 is fitted in the groove 13 of the fixing base 7. 7-2 is a cross-sectional view showing a state in which the connecting bolt 10 is fitted in the groove 13 of the fixing base 7. FIG. Next, as shown in FIGS. 7A and 7B, the connecting bolt 10 is inserted into the groove 13 of the fixing base 7 from the end face. The connecting bolt 10 is a metal bolt. Then, the connecting bolt 10 is moved along the groove 13 to a desired position. The connecting bolt 10 may be temporarily inserted into the groove 13 before the fixing base 7 is fixed to the roof structure by the fixing bolt 8.

  Next, the connecting bolt 10 is inserted into the through hole 94 of the connecting portion 9, and the through plate portion 93 of the connecting portion 9 and the wall portion 12 of the fixing base 7 are combined and temporarily fixed by the nut 11. In the state temporarily fixed by the nut 11, the connecting portion 9 can be easily moved in the longitudinal direction of the fixing base 7.

  In addition, if the some through-hole 94 is formed in the penetration board part 93 of the connection part 9, the connection part 9 can be fixed using the some bolt 10 for connection. In this case, the connecting portion 9 is fixed at a plurality of points, so that the rotation is prevented and the positional accuracy can be improved.

  Next, the position of the connecting portion 9 is adjusted so as to match the roof material 6, and the connecting bolt 10 and the nut 11 are finally tightened. And the installation to the installation attachment part 91 of the installation installed on a roof, restoration of a roof structure, etc. are performed.

  According to the fixture 50 described above, even if a wind load or a snow load is applied to the fixing base 7 through the equipment attached to the equipment mounting portion 91, the fixing base 7 is fixed to the rafter 2, so that it is sufficient. It is easy to ensure the load bearing performance, and it is possible to suppress the occurrence of rain leakage due to the breakage of the structure or the peeling of the fixed base 7 from the base plate 4 due to repeated stress.

  Moreover, since the fixing base 7 has substantially the same cross section in the longitudinal direction, the fixing base 7 can be manufactured by an extrusion method. Therefore, the manufacturing cost can be suppressed as compared with the case of manufacturing by bending.

  Further, the wall portion 12 is formed on the fixing base 7 having a plate shape, and the groove 13 into which the head portion 10a of the connecting bolt 10 is fitted is formed. The number of portions can be reduced, and the overall strength can be improved. In addition, since the groove 13 is formed over substantially the entire length of the fixed base 7, it is easy to ensure a sufficient width for adjusting the position of the connecting portion 9.

  Moreover, in the connection part 9, since the level | step difference is provided between the penetration board part 93 and the installation attachment part 91, as shown in FIG. 91 can be placed on the roofing material 61.

  In addition, although it demonstrated that the fixing stand 7 and the connection part 9 were comprised with the metal, if it was not restricted to this and sufficient intensity | strength was acquired, you may be comprised with other materials, such as a synthetic resin.

  FIG. 8A is an external perspective view showing a modified example of the fixing base 7. FIG. 8B is a plan view of the fixing base 7 shown in FIG. FIG. 8C is a front view of the fixed base 7 shown in FIG. FIG. 8D is a side view of the fixed base 7 shown in FIG. In the fixed base 7 according to the present modification, a thin plate portion 75 is provided on the long side in a plan view so as to stand in the height direction (the standing direction of the wall portion 12). The angle formed between the fixing base 7 and the thin plate portion 75 is approximately 90 degrees.

  By providing the thin plate portion 75, the section modulus with respect to the height direction of the fixed base 7 is increased, so that the load bearing performance is further improved, and installation in a stronger wind region and the like becomes possible. In addition, the height of the thin plate part 75 is lower than the standing height of the wall part 12, and interference with the connection part 9 is avoided.

  FIG. 9 is a side view showing another modification of the fixing base 7. In this modification, the angle formed by the thin plate portion 75 and the fixing base 7 is greater than 90 degrees. By making the angle formed by the thin plate portion 75 and the fixing base 7 greater than 90 degrees, rainwater flowing on the roofing 5 or the field plate 4 (see also FIG. 3) from the ridge side causes the wall portion 12 and the thin plate portion 75 to flow. Water in the gap between the two can be suppressed, and further improvement in waterproofness can be achieved.

  As described above, the fixture according to the present invention is useful for installation of equipment, and is particularly suitable for installation of equipment installed on a roof.
