Description

  The present invention relates to a support device used for installation of various devices such as a solar panel and an outdoor unit, and more particularly to a support device capable of maintaining a strong fixed state.

  As shown in FIG. 13 and FIG. 14 of the following Patent Document 1, the installation of the device is such that a bolt is set up on an installation portion for installing the device such as a roof, and the device is received by a nut that is screwed into the bolt. This is done by sandwiching and fixing the metal parts up and down.

  However, the nut, especially the lower nut, is always loosened because it receives the load of the receiving metal. If the lower nut is loosened, rattling will occur, which may not only provide a stable function of the equipment, but may also cause an accident. For this reason, it has been required to periodically check the tightness of the nut.

  Further, since the bolt is set up at the installation portion, when the installation portion has a waterproof layer, a special device as disclosed in Patent Document 1 is indispensable in order to maintain waterproofness.

  Furthermore, since the receiving metal object is fixed by being sandwiched by nuts screwed to the bolts, the bolts must be set up in the vertical direction correctly. In other words, the work required accuracy and was difficult.

JP 2011-226095 A

  The main object of the present invention is to make it possible to easily obtain a stable installation state that does not cause looseness over a long period of time, and to ensure waterproofness with a simple configuration as required.

Means therefor is a support device for fixing a receiving metal object for receiving an installation object on the support bolt with a nut screwed to a support bolt standing on the installation part, provided on the upper side of the receiving metal object, There is a loose hole in the center for inserting the support bolt, and there are clamped surfaces on both the top and bottom sides that can be tightened when fixed, and a sliding spherical surface that allows the angle of these clamped surfaces to be freely changed is in the middle of the vertical direction. An upper angle changing mechanism portion provided on the lower side of the metal fitting, a loose hole through which the support bolt is inserted at the center, and sandwiched surfaces that are tightened when fixed, on both upper and lower surfaces. A lower spherical surface changing mechanism portion having a sliding spherical surface in the middle of the vertical direction that can freely change the angle of the surface, and a convex spherical surface of the lower member having the convex spherical surface in the lower angle changing mechanism portion Below that When the lower end of the support cylinder portion that expands the diameter is formed at the lower end, and the clamped surface of the upper end of the upper angle changing mechanism portion receives the tightening force of the nut on the lower surface of the flange portion. It is a support device provided with an elastic material that is elastically deformable and press-contacts the opposite surface.

  In this configuration, the upper angle changing mechanism part that has received the tightening force by the nut presses the receiving metal and the lower angle changing mechanism part to the installation part side through the sandwiched surface while regulating with the support bolt and the loose hole, The support cylinder part of the lower angle change mechanism part stably supports the load, and the elastic material provided in the collar part at the lower end of the lower angle change mechanism part is compressed and deformed, and the repulsive force resisting the compression force To prevent the nut from loosening. The upper angle changing mechanism and the lower angle changing mechanism follow the inclination of the support bolt by making the convex spherical surface and the concave spherical surface slide relative to each other, and set the receiving object at a desired angle. If an elastic material is comprised with the material which functions as a water stop material as needed, it will stop water between opposing surfaces.

  According to this invention, since the tightening force by the nut is received by the elastic material, an installation state in which no looseness occurs can be obtained over a long period of time. Since the lower angle changing mechanism portion that receives the load has a support cylinder portion that expands toward the lower side, the load can be stably supported and the installation state is good.

  In addition, since the support device is composed of an upper angle change mechanism portion and a lower angle change mechanism portion that sandwich the metal object, the configuration is simple and the workability is good. In addition, the angle between the upper and lower clamped surfaces can be changed by the convex spherical surface and the concave spherical surface in the upper angle changing mechanism portion and the lower angle changing mechanism portion. The inclination can be absorbed, and the installation work is also easy in this respect.

  The water stoppage of the portion where the support bolt is erected can be easily obtained as necessary by using the elastic material at the lower end as the waterstop material.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a half sectional view showing a usage state of the support device 11, and FIG. 2 is an exploded perspective view of the support device 11. As shown in these drawings, the support device 11 receives an installation object (not shown) such as a device by a nut 14 that is screwed to a support bolt 13 erected on an installation part 12 such as a rooftop of a building. This is a device for fixing the metal receiver 15 on the support bolt 13. That is, the support device 11 fixes the metal receiving piece 15 on the support bolt 13 by tightening the nut 14.

  The receiving metal 15 has an appropriate shape. In the example of FIG. 1, an angle-shaped metal receiver 15 is shown. A loose hole 15a larger than a size corresponding to the fitting of the support bolt 13 is formed at a portion of the receiving metal 15 through which the support bolt 13 is inserted.

  The support device 11 includes an upper angle changing mechanism portion 21 provided on the upper side of the bracket 15 and a lower angle changing mechanism portion 31 provided on the lower side.

The upper angle changing mechanism portion 21 has loose holes 22 and 23 through which the support bolts 13 are inserted in the center, and sandwiched surfaces 24 and 25 that are tightened when fixed, on both upper and lower surfaces. Have a convex spherical surface 26 and a concave spherical surface 27 as sliding spherical surfaces that slide relative to each other so that the angle can be freely changed, and two members that are stacked vertically, that is, a spherical washer 28. And a sliding ring 29.

  As shown in FIG. 3, the spherical washer 28 is formed in a hollow, substantially hemispherical shape, and has an annular ground piece 28 a that protrudes in the outer peripheral direction at the lower end. The lower surface of the ground piece 28a is the sandwiched surface 24 of the lower surface. The upper surface of the spherical washer 28 is the convex spherical surface 26, and the loose hole 22 larger than the size corresponding to the fitting of the support bolt 13 is provided at the center.

  The sliding ring 29 has a substantially rectangular annular shape with a vertical cross section having a size on the convex spherical surface 26 of the spherical washer 28, and the central hole is the loose hole 23 larger than the support bolt 13 is fitted. . A concave spherical surface 27 corresponding to the convex spherical surface 26 is formed on the entire circumference of the inner corner portion on the lower surface of the sliding ring 29 so as to cut out the corners of the rectangular shape in the longitudinal section. The upper surface of the sliding ring 29 is the clamped surface 25 of the upper surface.

  Since the spherical washer 28 has a convex spherical surface 26 and the sliding ring 29 has a concave spherical surface 27, the relative sliding of the spherical washer 28 and the sliding ring 29 causes the upper and lower clamped surfaces 24 and 25 thereof to be clamped. Can be continuously tilted in any direction of 360 degrees.

Similar to the upper angle changing mechanism portion 21, the lower angle changing mechanism portion 31 has loose holes 32 and 33 through which the support bolts 13 are inserted in the center, and the clamped surfaces 34 and 35 that are tightened when fixed are vertically moved. It has a convex spherical surface 36 and a concave spherical surface 37 as sliding spherical surfaces that slide relative to each other so that the angles of the sandwiched surfaces 34 and 35 can be changed, and are vertically stacked. 2 members, that is, a load supporting cylinder 38 and a sliding ring 39.

  As shown in FIG. 4, the load support cylinder 38 is formed in a hollow, substantially conical shape, and the upper end portion is formed in a spherical shape. The upper surface of the upper end portion is the convex spherical surface 36, and the loose hole 32 larger than the size corresponding to the support bolt 13 is fitted at the center.

  Below the convex spherical surface 36 in the load support cylinder 38, a support cylinder part 38a that expands downward is formed, and an annular flange part 38b that extends to the outer periphery is formed at the lower end. The lower surface of the flange 38b is the sandwiched surface 34 of the lower surface. The lower surface of the collar portion 38b is provided with an elastically deformable elastic material 40 that presses against the opposing surface when receiving a tightening force from above. The elastic member 40 is formed in an annular shape with a rectangular shape in the longitudinal section. And the magnitude | size (outer diameter) of the elastic material 40 is set so that the outer peripheral surface of the elastic material 40 may be located in the position which retreated to the inner peripheral side rather than the outer peripheral surface of the collar part 38b. The elastic member 40 can be fixed to the flange 38b by adhesion or the like.

  The elastic member 40 is made of rubber and is formed so that the entire lower surface is in close pressure contact with the opposing surface to obtain water blocking properties. That is, the elastic member 40 is also a water stop material 40a.

  As shown in FIG. 5, a fitting convex portion 38 c into which the elastic material 40 is fitted may be provided on the lower surface of the flange portion 38 b including the elastic material 40 to increase the coupling strength. The fitting convex portion 38c may be provided on the entire circumference or partially.

  The sliding ring 39 has the same structure as the sliding ring 29 of the upper angle changing mechanism unit 21. In other words, the load supporting cylinder 38 is formed in an annular shape having a substantially rectangular cross section with a size on the convex spherical surface 36. The central hole is the loose hole 33 which is larger than the support bolt 13 corresponding to the fitting. A concave spherical surface 37 corresponding to the convex spherical surface 36 is formed on the entire circumference of the inner corner portion of the lower surface of the sliding ring 39 so as to cut out the corners of the rectangular shape in the longitudinal section. The upper surface of the sliding ring 39 is the sandwiched surface 35 of the upper surface.

  Since the load supporting cylinder 38 has a convex spherical surface 36 and the sliding ring 39 has a concave spherical surface 37, the upper and lower clamped surfaces 34 of the load supporting cylinder 38 and the sliding ring 39 are moved by relative sliding of the load supporting cylinder 38 and the sliding ring 39. , 35 can be continuously tilted in any direction of 360 degrees.

  The support device 11 configured as described above is used as follows.

  First, after preparing a pilot hole at a predetermined location of the installation portion 12, the anchor nut 16 is fixed as shown in FIG. Even if there is a waterproof layer 17, it is fixed as it is. When there is a heat insulating layer (not shown) under the waterproof layer 17, the anchor nut 16 is fixed after removing the heat insulating layer.

  Next, the lower end portion of the support bolt 13 is screwed and fixed to the anchor nut 16. A ready-made one can be used for the anchor nut 16 and the support bolt 13.

  For the support bolt 13 protruding upward from the installation portion 12, the lower angle changing mechanism portion 31, that is, the load support cylinder 38 and the sliding ring 39 are held in order. These holding operations can be easily performed because the members 38 and 39 have the loose holes 32 and 33, respectively.

  Subsequently, the metal receiver 15 is held with respect to the support bolt 13, and the metal receiver 15 is supported by the clamping surface 35 on the upper surface of the sliding ring 39 of the lower angle changing mechanism 31. At this time, the load supporting cylinder 38 and the sliding ring 39 are rotatable relative to each other, and the angle of the upper clamped surface 35 can be appropriately changed regardless of the angle of the lower clamped surface 34 of the load supporting cylinder 38. . For this reason, the sliding ring 39 is moved on the convex spherical surface 36 of the load supporting cylinder 38 so that the metal receiver 15 is in a predetermined posture.

  After the same work is performed on the required number of support fittings 11, the upper angle changing mechanism 21, that is, the spherical washer 28 and the sliding ring 29 are held in order with respect to the support bolt 13. Since these members 28 and 29 have the loose holes 22 and 23, these holding operations can be easily performed.

  Finally, the washer 18 and the nut 14 are held on the support bolt 13 that protrudes above the sliding ring 29 of the upper angle changing mechanism portion 21, and the nut 12 is tightened. For the washer 18 and the nut 14, ready-made ones can be used.

  Even if the spherical washer 28 of the upper angle changing mechanism portion 21 is inclined with respect to the support bolt 13, the sliding ring 29 tightened by the nut 14 is in a posture orthogonal to the longitudinal direction of the support bolt 13, like the nut 14. The spherical washer 28, the receiving metal 15, and the lower angle changing mechanism portion 31 are pressed against the installation portion 12. By this pressing, the elastic member 40 at the lower end of the load supporting cylinder 38 comes into pressure contact with the waterproof layer 17 of the installation portion 12 and obtains water blocking properties. When the elastic member 40 comes into pressure contact, the elastic member 40 exerts an elastic force and tries to push back against compression. For this reason, the nut is in a state similar to that provided with a lock nut, and a water stop state is obtained, and at the same time, a fixed state without loosening is obtained.

  When caulking 20 is performed around the elastic material 40 at the lower end, that is, below the flange portion 38b, the water stop performance can be further improved.

  In addition, the load support cylinder 38 has a support cylinder part 38a that expands downward, and transmits the pressure contact force evenly to the annular flange part 38b at the lower end, so that the stability during the pressure contact is good.

  In addition, since the lower angle changing mechanism 31 and the upper angle changing mechanism 21 are sequentially held with respect to the support bolt 13 with the receiving metal 15 interposed therebetween, and can be fixed as described above by simply tightening with the nut 14. Also, there are advantages that workability is good, the number of parts is small, and the configuration is simple.

  The lower angle changing mechanism portion 31 and the upper angle changing mechanism portion 21 have convex spherical surfaces 26 and 36 and concave spherical surfaces 27 and 37, and can be fixed while absorbing the difference in angle between the support bolt 13 and the receiving metal 15. Yes. For this reason, high accuracy is not required when fixing the anchor nut 16, work can be easily performed, and even if there is an error in fixing the anchor nut 16, desired and correct installation can be performed.

For example, as shown in FIG. 6, even when the support bolt 13 is inclined because the anchor nut 16 is inclined or when the support bolt 13 is inclined because the installation portion 12 is inclined, By appropriately changing the posture of the member, a stable fixed state can be obtained as described above.

Furthermore, since the elastic member 40 at the lower end of the lower angle changing mechanism part 31 plays a role as the water stop material 40a, the water stop function automatically with the installation part 12 if the fixing is performed according to the procedure described above. Without using a special structure just for water stoppage.
It is possible to automatically stop water with a structure to support. In this way, the number of parts and work man-hours can be reduced, which is efficient.

  Other examples will be described below. In this description, parts that are the same as or equivalent to those in the above-described configuration are given the same reference numerals, and detailed descriptions thereof are omitted.

  FIG. 7 is a partial cross-sectional front view showing another example of the load support cylinder 38. The load support cylinder 38 has a height adjusting means for adjusting the height between the support cylinder portion 38a and the flange portion 38b. 41. The height adjusting means 41 is a screw. That is, the load support cylinder 38 includes an upper member 42 having a support cylinder portion 38a and a lower member 43 having a flange portion 38b, and a cylindrical extension 44 is formed below the support cylinder portion 38a in the upper member 42. In addition, the insertion tube portion 45 fitted into the extension portion 44 is formed above the flange portion 38 b of the lower member 43. A female screw 44 a is formed on the inner peripheral surface of the extension portion 44, and a male screw 45 a is formed on the outer peripheral surface of the insertion tube portion 45.

  Such a load support cylinder 38 can change the overall height as shown in FIG. 8 by performing relative rotation of the upper member 42 and the lower member 43. The height can be adjusted before the nut 14 is tightened, or even after the nut 14 has been tightened once, the nut 14 can be loosened.

  When the load supporting cylinder 38 having the height adjusting means 41 is used as described above, the height for supporting the metal receiving piece 15 can be adjusted, so that the adjustment work performed between the metal receiving piece 15 and the device it receives can be omitted. There is an advantage that the adjustment range can be narrowed.

  FIG. 9 is a partial cross-sectional view showing another example of use of the support device 11. As shown in this figure, the auxiliary member 19 that supports the metal receiving piece 15 can be sandwiched under the lower angle changing mechanism portion 31.

  The auxiliary member 19 includes a sandwiched piece 19a having a size capable of supporting the flange portion 38b of the load support cylinder 38 and a plurality of support pieces 19b extending obliquely upward from the periphery of the sandwiched piece 19a. An elastic material 19c is provided on the lower surface of the sandwiched piece 19a in the same manner as the elastic material 40 at the lower end of the load supporting cylinder 38. The support pieces 19b all extend at the same angle, and a receiving piece 19d extending horizontally is formed at the upper end.

  The metal receiver 15 includes a connecting member 15b and a receiving member 15c. The connecting member 15b connects each support piece 19b and the support device 11, and is formed by punching a single plate material or a predetermined shape thereof. A through hole is formed in a portion corresponding to the receiving piece 19d at the upper end of the support piece 19b. (Not shown) is formed. The receiving member 15b is fixed at a position corresponding to the receiving piece 19d in the connecting member 15a, and is formed in an appropriate shape.

  When using the auxiliary member 19 and the metal receiver 15 having such a configuration, the auxiliary member 19 is held before the lower angle changing mechanism 31 is supported by the support bolt 13. Subsequent operations are the same as described above, and the connecting member 15b is fixed between the upper angle changing mechanism 21 and the lower angle changing mechanism 31. The fixed connecting member 15b and the receiving piece 19d of the auxiliary member 19 are fixed together with the receiving member 15c by bolts 51 and nuts 52. Further, it is preferable to perform caulking 20 under the sandwiched piece 19a of the auxiliary member 19 in the same manner as described above.

  If the load supporting cylinder 38 has the height adjusting means 41 as shown in FIG. 7, it may be easy to cope with the case where the anchor nut 16 cannot be fixed as desired.

  When the auxiliary member 19 is used in this manner, the elastic member 19c of the sandwiched piece 19a of the auxiliary member 19 is pressed against the installation portion 12, so that a fixed state having water-stopping and stability can be obtained as described above.

  In addition, the receiving member 15 c that supports the device to be installed in the metal receiver 15 is fixed via a bolt 51 fixed to the receiving piece 19 d of the auxiliary member 19. Depending on the number of support pieces 19b, two-point support, three-point support, and four-point support are supported.

  That is, when such an auxiliary member 19 is used, the number of anchor nuts 16 can be reduced from the number of points to be supported, and the work can be simplified.

In the correspondence between the configuration of the present invention and the configuration of the above-described embodiment,
The sliding spherical surface of the present invention corresponds to the convex spherical surfaces 26, 36 and the concave spherical surfaces 27, 37,
Similarly,
The opposing surface corresponds to the installation portion 12 and the sandwiched piece 19a of the auxiliary member 19,
The present invention is not limited to the above-described configuration, and other configurations can be adopted.

  For example, the sliding spherical surface may be composed only of a convex spherical surface, and the portion corresponding to the convex spherical surface may be a simple annular ring shape having no concave spherical surface.

  Further, the elastic material can be composed of a leaf spring or the like in addition to rubber.
