When there is no bottom 1f, it may be in contact with the pedestal 1a. As described above, the lower end portion 35 is in contact with the bottom surface 1f of the support portion 1b or the pedestal portion 1a, so that the compressive strength is increased and the installation object can be more stably fixed.
Further, when the lower end portion 35 is in contact with the bottom surface 1f or the pedestal portion 1a of the support portion 1b, a female screw 19 (not shown) is provided on the bottom surface 1f of the support portion or the upper surface of the pedestal portion 1a to provide a screw for the lower end portion 35. It can be fixed more firmly by screwing the part.

As another embodiment, as shown in FIG. 8, the retaining portion 16 having the female screw 18 may be integrated with the upper end surface 1c. The connecting portion 34 of the installation object fixing portion 1e is provided with a male screw, and the connecting portion 34 is screwed and fixed to the female screw 18 of the retaining portion 16 integrated with the upper end surface 1c. In this case, the female screw 18 of the retaining portion 16 is exposed as viewed from the upper end surface 1c before the installation object fixing portion 1e is screwed.
As an aspect in which the retaining portion 16 having such a female screw 18 is integrated with the upper end surface 1c, there is an example in which the female screw 18 is provided on the top plate of the support portion 1b constituting the upper end surface 1c.

Further, the retaining portion 16 integrated with the upper end surface 1c is configured such that the lower end portion 35 of the installation object fixing portion 1e does not completely penetrate the upper end surface 1c as shown in FIG. 8 (8-1). I can do it. Further, as shown in FIG. 8 (8-2), the lower end portion 35 may penetrate the upper end surface 1c, and the lower end portion 35 is in contact with the bottom surface 1f of the support portion 1b or the pedestal portion 1a. You can also.
In this case, as shown in FIGS. 9A and 9B, the female screw 19 is provided on the bottom surface 1f of the support portion or the upper surface of the pedestal portion 1a, and the screw portion provided on the lower end portion 35 is screwed. It can fix more firmly.

  Further, as shown in FIGS. 10 (10-1) and (10-2), the retaining portion 16 can be provided inside the supporting portion 1b while being connected to the supporting portion 1b. When the female screw 18 is provided in the retaining portion 16, the upper end surface 1 c is provided with an opening at a position corresponding to the female screw 18. The connecting part 34 of the installation object fixing part 1e is provided with a male screw, the installation object fixing part 1e is screwed into the female thread 18 of the retaining part 16, and the fixing nut 1d is screwed into the male screw part 33. The upper end surface 1 c is firmly fixed by being sandwiched between the fixing nut 1 d and the retaining portion 16.

  As shown in FIG. 10 (10-2), the retaining portion 16 can be provided apart from the upper end surface 1c. When the female screw 18 is provided in the retaining portion 16, the upper end surface 1 c is provided with an opening at a position corresponding to the female screw 18. Further, the connection part 34 of the installation object fixing part 1e is provided with a male screw, the installation object fixing part 1e is screwed into the female screw 18 of the retaining part 16, and the installation object fixing part 1e is opened from the opening of the upper end surface 1c. The installed object fixing portion 1e is fixed to the support portion 1b by screwing the lower end of the lower portion.

  Furthermore, these configurations can be combined. For example, as shown in FIG. 11, a female thread portion can be provided on the upper end surface 1c and the bolt head 20 can be connected.

  In addition, the pedestal portion 1a and the support portion 1b only need to be integrated. However, in the case where the pedestal portion 1a and the support portion 1b are formed as separate members and joined together, the installation object fixing portion 1e is attached to the support portion 1b with a fixing nut 1d. After fixing, it can be integrated with the pedestal 1a.

  Here, the pedestal portion 1a is a grounding portion that is a basis for installation on a base surface or the like. Therefore, the diameter is preferably larger than the diameter of the support portion 1b connected thereon. Further, the outer shape of the pedestal portion 1b may be a polygon such as a triangle, a quadrangle, a circle, or an indeterminate shape when viewed from the surface (upper surface) facing the base surface, but the load applied to the pedestal portion can be dispersed. A circular shape is preferable from the viewpoint of possible.

  Furthermore, it is preferable that the pedestal portion 1a has an opening for fixing with a support frame fixing screw for fixing to the base. It is preferable to install a plurality of openings, preferably 2 to 8, and more preferably 4 to 6.

  In particular, when installing an installation support base on a lightweight cellular concrete (ALC) base, the fixing strength per support base fixing screw is not sufficient, so a plurality of support base fixing screws may be provided. More preferably, the number of openings provided in the pedestal portion is preferably 5 to 7.

  The pedestal can be made of synthetic resin, metal, wood, etc., but is preferably made of metal from the viewpoint of strength and durability, and steel is more preferable. Further, the outer shape of the pedestal portion 1a can be 50 mm to 500 mm, and when it is made of metal, the thickness of the metal plate used is preferably 1.0 mm to 20 mm, and considering the strength and cost, 3.0 mm to 10 mm Is more preferable.

  Similarly to the pedestal portion, the support portion can be made of metal, wood, or the like. However, if the pedestal portion is made of metal, it can be integrated by welding, and is preferably made of metal. Further, the pedestal portion and the support portion may be integrally formed of metal, or these may be integrally formed of synthetic resin.

  Here, the pedestal portion 1a is installed on the upper side of the base, but it may be installed directly on the base, or indirectly after laying a waterproof sheet, a buffer sheet, a heat insulating material, a non-combustible board, etc. on the base. Can also be installed.

The shape of the support portion 1b is preferably a columnar shape such as a columnar shape or a prismatic shape, but may be any other shape as long as it is provided on the pedestal portion to support the installation object. Further, the support portion may be a single stage or a multistage structure.
The upper end surface 1c of the support portion 1b may be a polygon such as a triangle, a quadrangle, or the like, or a circle or an indeterminate shape, but a circle is preferable because the load applied to the support portion can be dispersed. Moreover, since a support part is connected to the upper surface of a base part, it is preferable that the diameter of a support part is the same as that of the diameter of a base part, or is small. Furthermore, in consideration of the fact that an opening for allowing the support base fixing screw to pass through may be provided in the pedestal portion, the diameter of the support portion is preferably smaller than the diameter of the pedestal portion. More preferably, the diameter is 1/4 to 3/4.

Specifically, the diameter of the support portion can be 20 mm to 450 mm. The thickness is preferably 1.0 mm to 10 mm, and more preferably 3.0 mm to 7.0 mm in view of strength and cost.

Here, the height of the support portion can be set to a desired height depending on the fixed position of the installation object. That is, in the installation object support frame of this invention, a support part can serve as the raising part which adjusts the fixed position of an installation object. In this way, since the support portion also serves as a raised portion, not only can the height of the installation be set to a desired position, but also the pedestal is firmly fixed to the base and the housing, Even if is fixed at a high position, the installation object can be stably installed and held.
In addition, when only the bolt that fixes the installation object is extended and installed at a high position, the stability of the fixation is affected by the strength of the bolt, but by using the raised part as the support part, the load from the side can be reduced. It also becomes stronger.

Therefore, although the height of the support portion can be arbitrarily determined, it is preferably 50 mm to 300 mm, and more preferably 125 mm to 250 mm in consideration of installation workability of the installation object. In particular, when installing a panel for photovoltaic power generation, electrical wiring is required together with the installation of the panel, and it is preferable to perform these operations at a high position because workability is improved.

An installation fixture is formed on the upper end surface of the support. Furthermore, since the set object fixing portion is fixed to the support portion with a fixing nut, the upper end surface is preferably substantially flat in order to firmly fix the installation object fixing portion.
Although the diameter of the upper end surface may be the same as the diameter of the installation object support frame, the diameter of the upper end surface may be smaller than the diameter of the support portion when the support portion has a multistage structure. Moreover, the diameter of the upper end surface can be made larger than the diameter of the support portion to form a flange shape.
Here, the thickness of the upper end surface is preferably 1.0 mm to 100 mm, and more preferably 3.0 mm to 50 mm. In particular, when the retaining portion is integrated with the upper end surface, a thicker upper end surface is preferable because the fixing strength is increased, and a female screw can be provided on the upper end surface. Therefore, the thickness of the upper end surface in this case is preferably 30 mm to 80 mm, more preferably 50 mm to 70 mm.

The installation object fixing part is provided to connect the installation object to the installation object support frame. Accordingly, the diameter is preferably 5 mm to 30 mm, more preferably 10 mm to 24 mm from the viewpoint of strength.

The installation object fixing part has an external thread at least at a part in contact with the upper end surface of the support part, and an installation object connection part for connecting the installation object to the open side end part. When a male screw is provided in the installation object connection part, the installation object fixing part may have at least a bolt shaft. And the aspect at the time of using an installation fixture fixing | fixed part as a volt | bolt was illustrated in FIG.

When the bolt shaft 21 has the bolt head 20 as shown in FIG. 12 (12-1), the bolt head 20 can be used as the retaining portion 16. The bolt shaft portion 21 is provided with a male screw, the open end portion 31 side becomes the installation object connection portion 32, and the bolt head 20 side becomes the male screw portion 33. Here, a square, hexagonal, round, pan, flat, round spatula, flat, round flat, etc. can be used for the bolt head, and besides these, T bolts, eye bolts, butterfly bolts, hook bolts, etc. are used.

Further, as shown in FIG. 12 (12-2), female screws can be provided at both ends of the bolt shaft portion 21. In this case, one end side is the installation object connection portion 32 and the other is the male screw portion 33. Further, by providing a male screw further from the male screw portion 33 to the lower end portion 35 side, the connecting portion 34 can be connected to the retaining portion 16 having a female screw.
Furthermore, a male screw can be provided over the entire length of the bolt shaft portion 21 as shown in FIG. 12 (12-3).

  Since the fixing nut is screwed into the installation object fixing part, the fixing nut has a female screw part corresponding to the installation object fixing part. Also, the installation fixture is fixed to the support by screwing the fixing nut, and the installation is stably held in a state where the installation is connected to the installation fixture. The Therefore, the larger diameter in the outer shape of the fixing nut is preferable, and the diameter of the outer shape of the fixing nut with respect to the diameter of the upper end surface of the support portion is preferably 10% to 100%, and more preferably 20% to 80% in consideration of strength and cost. 30% to 60% is more preferable. The thickness of the fixing nut is preferably 2 mm to 30 mm and more preferably 5 mm to 15 mm for the same reason as described above.

As the outer shape of the fixing nut, a square nut, a hexagonal nut, a round nut, a nut with a seat, a nut with a flange, or the like can be used. Of these, a round nut or the like having a cylindrical outer shape is preferable. According to this configuration, even if a lateral load is applied from any direction to the installation fixture fixing portion, the load is dispersed without concentrating on one point, so that the bending strength of the installation fixture fixing portion is increased. In addition, since there are no corners as in general hex nuts, if the fixing nut tilts as the installation fixing part bends due to a load from the side, the upper end surface of the supporting part and the fixing There is no risk that the contact portion of the nut will be damaged even when the fixing nut is tilted.

  Here, by making the fastening nut tightening torque constant, the mounting strength of the support part and the fixture fixing part varies more than when the bolts for fixing the fixture are connected to the mount by welding or bonding. Therefore, a stable fixing strength can be obtained when fixing the installation object. Specifically, the tightening torque of the fixing nut 1d is preferably 40 N · m to 70 N · m.

  Moreover, it is preferable to coat the installation object support frame with a thermoplastic resin layer. By covering at least the pedestal part with a thermoplastic resin layer, when installing the installation object support frame on the thermoplastic resin sheet which is a waterproof layer and waterproofing and reinforcing the thermoplastic resin sheet and the pedestal part with a reinforcing sheet, It becomes easy to perform welding and adhesion such as thermal welding between the reinforcing sheet and the thermoplastic resin layer coated on the pedestal.

  Moreover, it can prevent that an installation thing support stand itself corrodes or deteriorates by coat | covering with a thermoplastic resin layer. Therefore, it is possible to cover the entire installation object support frame, and it is also possible to cover the base part, the support part, and the fixing nut excluding the installation object fixing part. Furthermore, it is also possible to cover up to the vicinity of the joint portion of the installation object fixing portion with the fixing nut. Specifically, the support base covering resin layer 8 can cover the portion from the base portion to the upper 5 mm to 10 mm portion of the fixing nut in the installation object fixing portion. In this way, when the position where the installation object fixing portion is covered and the installation object is fixed corresponds to this covered portion, the installation object can be fixed by cutting and removing the coating portion. Moreover, it is more preferable to end-process the upper end part of the coating layer by a thermoplastic resin layer with a liquid sealer etc.

The thickness of the support base coating resin layer 8 is preferably 1 mm to 10 mm, and more preferably 3 mm to 7 mm. The thermoplastic resin to be coated preferably has the same or similar composition from the viewpoint that it is easily welded to the reinforcing sheet 5 and the thermoplastic resin waterproof sheet 3. More specifically, vinyl chloride resin, olefin resin, and acrylic resin are preferably used.

Such a support frame covering resin layer is preferably formed by dipping in order to cover the three-dimensional installation object support frame. Thereby, a support frame covering resin layer can be provided along the shape of the installation object support frame.

  FIG. 1 which is the first embodiment of the installation structure of the installation object support frame using the installation object support frame of the present invention will be described in more detail.

FIG. 1 shows one embodiment in which the installation object support frame of the present invention is placed on a roof slab. After laying the thermoplastic resin waterproof sheet 3 as a waterproof layer on the concrete frame 2, the installation support frame is fixed to the frame 2 through the thermoplastic resin sheet 3 with the support frame fixing screws 4. This is a structure for mounting an object support frame.
Further, in FIG. 1, the pedestal portion 1a of the installation object support base and the thermoplastic resin waterproof sheet 3 are integrated by heat welding, solvent welding or the like by means of the reinforcing sheet 5, and the ends of the fusion bonding portion are sealed with the sealing material 6. It is a stopped structure. This is a preferred embodiment from the viewpoint of further improving the waterproofness in the installation part of the installation object support frame.

The installation object support frame is installed on a waterproof layer laminated on the casing, but the casing is not particularly limited, and a concrete base, a metal base, lightweight foamed concrete (ALC), steel, or the like is used. Moreover, you may laminate | stack other layers, such as an inorganic board and a mortar material layer, between a housing and a waterproof layer. Although the installation support stand can be installed directly on the concrete base or steel frame itself, the installation support support stand can be installed on the waterproof layer from the standpoint that the installation can be installed on the existing waterproof layer. It is preferable to install.

The waterproof layer is preferably a thermoplastic resin sheet, and a vinyl chloride resin, a polyolefin resin, an acrylic resin, or the like can be used. The waterproof sheet made of vinyl chloride resin is more preferable from the viewpoint that the waterproof sheet can be bonded by hot melt bonding or solvent welding and can be reinforced by the reinforcing sheet.

The thermoplastic resin sheet may be a single layer, but is preferably a multilayer product in which base layers such as glass cloth and nonwoven fabric are laminated from the viewpoint of excellent dimensional stability and tensile strength. The base material layer may be provided in the lowermost layer, but may be provided in the middle of the thermoplastic resin layer.
