The outer insertion cylinder part 53 of the waterproof base member 50 in the illustrated example is an integral part of the cylindrical part 51 and the tip ring part 52a of the waterproof base body 52 attached to the cylindrical part 51 on the same axis. It is. The outer insertion cylinder portion 53 of the waterproof base member 50 in the illustrated example is formed in a cylindrical shape having an inner diameter substantially the same as the outer diameter of the main column portion 32 of the column member 30 (same as or slightly larger than the outer diameter of the main column portion 32). Has been. The inner side of the outer insertion cylinder portion 53 is a main column member insertion hole 53a (see FIG. 7) which is a through hole for extrapolating to the main column portion 32.
Further, in this waterproof base member 50, the entire portion other than the tip ring portion 52a of the waterproof base body 52 functions as the waterproof overhang portion 50a.
As shown in FIG. 7, the contact portion 52 c of the waterproof base member 50 in the illustrated example has a rectangular plate shape, but the contact portion has a shape other than a square shape. A polygonal plate shape or a circular shape can also be used.

The waterproof base member 50 assembles the foundation anchor 10 into a construction target structure such as the base 3 (see FIG. 1) where the outer layer 5 is not provided or the outer layer 5 (see FIG. 13) provided on the base 3. In the construction work, the main column member 30 is fixed to the concrete base material 3 and is extrapolated from the tip side (tip side) to the column portion 32 of the main column member 30 erected with respect to the main column portion 32. By sliding and moving in the axial direction, the outer peripheral portion (here, the contact portion 52c) of the waterproof overhang portion 50a is provided in contact with the surface of the construction target structure over the entire periphery. And this waterproof base member 50 is a waterproof layer (cover waterproof) which covers the boundary part 52d between the contact part 52c contacted to the construction target structure surface and the construction target structure surface located around the contact part 52c. In order to prevent intrusion of water from the boundary part 52d to the inside (inner surface side) of the cover part 52b, the outer part is attached to the support part 32 of the main pillar member 30 that is fixed and erected on the base 3. Inserted and provided. The cover waterproof layer (see the waterproof layer 60 in FIG. 1 and the cover waterproof layer 61 in FIG. 13) covering the boundary 52d is a construction target structure located around the contact portion 52c on the outer periphery of the waterproof overhang 50a. The waterproof base member 50 is formed continuously from the surface over the surface opposite the construction target structure of the waterproof overhang portion 50a (the surface of the overhang portion).
However, the waterproof base member 50 is disposed at a position where the extrapolated cylinder portion 53 is located on the proximal end side of the main column portion 32 with respect to the fixing screw hole 39, avoiding the fixing screw hole 39 of the main column portion 32. .

  As shown in FIG. 1, when assembling the foundation anchor 10 on the base 3 on which the outer layer 5 is not provided, the waterproof base member 50 is fixed to the concrete base material 3 and the main column member 30 is erected. In the state where it is extrapolated to the column part 32, the base part side contact part 31 of the main column member 30 is housed inside the cover part 52b of the waterproof base body 52, so that the contact part 52c is the base (concrete base material 3). Can be brought into contact with the upper surface 3a.

The contact portion 52c is in contact with the construction target structure (the surface of the base 3 in FIG. 1) on a virtual plane perpendicular to the central axis of the waterproof base member 50 over the entire circumference (the whole in the illustrated example). The region is formed, and the entire contact region can be brought into contact with the flat base surface.
The configuration of the abutting portion is the same as that of the waterproof base member according to another embodiment of the present invention. Further, as illustrated in FIG. 13, the relationship between the contact portion 52c of the waterproof base member 50 and the surface of the flat outer layer 5 provided on the base surface is the same as the relationship between the contact portion 52c and the base surface. It is. The contact portion 52c can be brought into contact with the flat outer layer 5 surface over the entire circumference.

The contact portion 52c is formed in a thin plate shape. For this reason, the waterproof base member 50 has a small step between the contact portion 52c in the boundary portion 52d and the surrounding base surface. For this reason, the waterproof base member 50 has a waterproof layer (waterproof layer in FIG. 1) that extends from the surface of the construction target structure positioned around the contact portion 52c to the surface of the overhang portion of the waterproof overhang portion 50a of the waterproof base member 50.

Further, the waterproof base member is not limited to the configuration having the cylindrical portion 51 that is separate from the waterproof base member in addition to the waterproof base main body, and has a configuration in which the cylindrical portion 51 is integrated with the waterproof base main body. Can also be adopted. Furthermore, as the waterproof base body and the cylindrical portion, a configuration formed by a plurality of members can be employed.

As shown in FIGS. 1 and 13, the waterproof base member 50 in the illustrated example has the extrapolated cylinder portion 53 extrapolated inside the extrapolated cylinder portion 53 (specifically, the inner side of the cylindrical portion 51). An O-ring 54 that is in close contact with the outer peripheral surface of the column 32 is provided. The O-ring 54 prevents water that has entered the gap between the upper end of the extrapolated cylinder portion 53 and the outer peripheral surface of the main pillar portion 32 inside thereof from reaching the lower base 3 from the waterproof base member 50.
The O-ring 54 is provided along the inner periphery of the extrapolation cylinder portion 53 and is extrapolated to the support column 32 when the extrapolation tube portion 53 is extrapolated to the support column 32. Further, the O-ring 54 extrapolated to the support column 32 is slidable in the axial direction of the support column 32 with respect to the outer peripheral surface of the support column 32. By this sliding, the support column portion of the waterproof base member 50 is slid. Its axial position relative to 32 can be adjusted.

In addition to the above, the foundation anchor 10 of this embodiment has a cup-shaped cover 70 attached to the bolted tip member 40. The cup-shaped cover 70 in the illustrated example is attached to a portion located on the upper side from the tip end of the column portion 32 when screwed to the column portion 32.
As shown in FIGS. 1 and 11, the cup-shaped cover 70 has a top plate portion 70a at one end in the axial direction of the cylindrical side wall portion 70b, and is formed in a bottomed cylindrical shape with the other end in the axial direction opened. Has been. The cup-shaped cover 70 is formed of metal or resin. Further, the top plate portion 70a is formed with a bolt hole 71 for allowing the bolt portion 43 of the bolted tip member 40 to pass therethrough.
The cup-shaped cover 70 in the illustrated example is externally inserted into the bolt portion 43 of the bolted tip member 40 that is passed through the bolt hole 71 of the top plate portion 70a, and is tightened and fixed by a nut screwed to the bolt portion 43, for example. Thus, the bolted tip member 40 is fixed. Further, the cup-shaped cover 70 is fixed to the bolted tip member 40 with the opening at the lower end and the top plate portion 70a in the direction of the upper end, and the main column portion 32 of the main column member 30 and the bolted tip are inside thereof. The boundary portion 47 with the member 40 is covered, and the function of preventing water from entering from the boundary portion 47 is achieved.

FIG. 1 shows that the top plate portion 70a of the cup-shaped cover 70 extrapolated to the bolt portion 43 is brought into contact with the tip end surface 42a of the mounting portion 42 of the tip member 40 with bolt, and the nut 4a screwed to the bolt portion 43 is tightened. The structure which fixes the cup-shaped cover 70 and the attachment (a part of support frame 4) extrapolated to the bolt part 43 to the tip member 40 with a bolt is illustrated. The front end surface 42 a of the mounting portion 42 of the front end member 40 with bolt is formed so as to be able to contact the entire circumference of the bolt hole 71 in the top plate portion 70 a of the cup-shaped cover 70 that is externally inserted into the bolt portion 43. .
However, the structure for fixing the cup-shaped cover 70 to the bolted tip member 40 is not limited to the configuration of the illustrated example. For example, the top plate portion 70a of the cup-shaped cover 70 that is extrapolated to the bolt portion 43 is used as the bolt portion. It is also possible to employ a configuration in which the nuts 43 are fastened and fixed between two nuts that are screwed in two longitudinally spaced locations. A spacer externally attached to the bolt portion 43 may be interposed between the top plate portion 70 a of the cup-shaped cover 70 and the mounting portion 42 of the tip member 40 with bolt.

Next, the construction method of the foundation anchor 10 of this embodiment will be described.
Here, first, as shown in FIG. 1, an example of a construction method in the case of assembling and constructing the foundation anchor 10 on the base 3 on which the outer layer 5 is not provided will be described.
As shown in FIG. 2, first, the lower hole 11 is drilled in the concrete base material 3 with a drill or the like, and the lower hole 11 is filled with the filler 12. Then, as shown in FIG. 3, the sleeve-like main body 23 of the fixing anchor 20 assembled to the proximal end contact portion 31 is inserted into the lower hole 11 from the distal end side by screwing the male screw portion 22 and the female screw hole 35. Then, the base end side contact portion 31 (specifically, the bottom surface 33 b) of the main column member 30 is brought into contact with the surface 3 a of the concrete base material 3. Next, the expansion portion of the fixing anchor 20 is expanded to fix the fixing anchor 20 to the concrete base material 3. The base end side contact portion 31 is fixed in a state of being in contact with the surface 3 a of the concrete base material 3 simultaneously with fixing of the anchoring anchor 20 to the concrete base material 3.

As the filler 12, for example, a liquid adhesive capable of bonding and fixing the fixing anchor 20 to the concrete base material 3 can be used. As this adhesive, for example, an epoxy-based adhesive used for fixing the adhesive anchor to the concrete base material can be used. The base end side contact portion 31 can secure sufficient fixing strength to the concrete base material 3 by the mechanical fixing force of the anchoring anchor 20 to the concrete base material 3. Use of the adhesive can increase the fixing strength of the anchor 20 for fixing to the concrete base material 3. In addition, as the adhesive, a resin adhesive that exhibits waterproofness after curing can be suitably used.
Further, the filler 12 is a curable liquid filler that exhibits adhesive strength for fixing and fixing the fixing anchor 20 to the concrete base material 3 by curing, or that exhibits waterproofness by curing. What is necessary is just and it is not limited to an adhesive agent.

  A concave portion 37 is formed on the bottom surface 33 b of the base portion 33 of the base end side contact portion 31. The concave portion 37 is formed around the female screw hole 35 and communicates with the female screw hole 35. For this reason, the base end side contact portion 31 fills the recess 37 with the filler 12 overflowing from the lower hole 11 when the bottom surface 33 b of the base portion 33 is brought into contact with the flat surface 3 a of the concrete base material 3. it can. Accordingly, the concave portion 37 of the base end side contact portion 31 is effective in improving the fixing strength of the base end side contact portion 31 with respect to the concrete base material 3 by filling the filler 12 when the filler 12 is an adhesive. Contribute to.

  When the fixing of the base end side contact portion 31 to the concrete base material 3 is completed, the main column portion 32 is then attached to the cylindrical screw portion 34 of the base end side contact portion 31 as shown in FIG. The main pillar member 30 is assembled. The main column portion 32 is screwed into the outer screw portion 36 formed on the cylindrical screw portion 34 of the proximal end side contact portion 31 and tightened to the proximal end contact portion 31 to be firmly fixed.

Thereafter, as shown in FIG. 6, the waterproof base member 50 is extrapolated from the front end side to the main column portion 32 of the main column member 30, and the outer side of the main column portion 32 is slid along the axial direction to make contact. The part 52 c is brought into contact with the surface 3 a of the concrete base material 3.
Next, the waterproof layer 60 is applied. Further, the end of the waterproof layer 60 formed on the waterproof layer construction surface (outside surface) of the waterproof base member 50 and between the distal end (upper end) of the extrapolated tube portion 53 of the waterproof base member 50 and the main column portion 32. A sealing material 55 is applied to ensure waterproofness.
As shown in FIG. 12, the waterproof layer 60 is provided over the entire surface 3 a of the concrete base material 3 excluding the portion covered with the waterproof base member 50. As shown in FIG. 6, the waterproof layer 60 is also applied to the waterproof layer construction surface of the waterproof base member 50 from the surface 3 a of the concrete base material 3 positioned around the outer periphery of the waterproof overhang 50 a of the waterproof base member 50. It extends continuously and covers the boundary 52d (see FIG. 1) between the outer periphery of the waterproof overhang 50a and the surface 3a of the concrete base material 3 located around it.

  After the construction of the waterproof layer 60, as shown in FIG. 10, the cup-shaped cover 70 is extrapolated to the bolt part 43 of the bolted tip member 40 and attached to the bolted tip member 40. The foundation anchor 10 fixes the cup-shaped cover 70 to the bolted tip member 40 by, for example, tightening using the nut 4a (see FIG. 1) screwed to the bolt portion 43 of the bolted tip member 40. This completes the assembly (construction).

As shown in FIG. 13, when the foundation anchor 10 is assembled and constructed in a structure with an outer layer having a structure in which the outer layer 5 is provided on the surface of the foundation 3, first, the construction that reaches the foundation 3 on the outer layer 5. The base pillar member 30 is fixed to the base 3 exposed to the bottom of the construction hole 5c by using the fixing anchor 20, and the main pillar member 30 is fixed. 30 is installed in a standing state.
Next, the waterproof base member 50 is extrapolated to the main column portion 32 of the main column member 30, and the abutting portion 52 c is brought into contact with the outer layer 5 to be placed on the outer layer 5. The position of the waterproof base member 50 in the axial direction with respect to the main column portion 32 is determined by the thickness of the outer layer 5. A chain line in FIG. 1 indicates adjustment in the height direction of the waterproof base member 50 with respect to the main column portion 32.

When the construction of the main column member 30 is completed, the waterproof base member 50 is extrapolated from the front end side to the main column portion 32 of the main column member 30 and placed on the outer layer 5, and the contact portion 52c of the waterproof base member 50 is placed. And forming a waterproof cover layer 61 that covers the boundary between the outer layer 5 and the surface of the outer layer 5 positioned around the outer peripheral layer 5, installing a sealing material 55 at the end of the cover waterproof layer 61 positioned on the outer surface of the waterproof base member 50, etc. Perform waterproofing. The construction hole 5c of the outer layer 5 is located inside the abutting region of the abutting portion 52c of the waterproof base member 50 in which the entire opening opening on the outer layer 5 surface is extrapolated to the main column portion 32 of the main column member 30. It is formed so that it may be located.
Next, as described with reference to FIG. 1, the assembly (construction) of the foundation anchor 10 is completed by attaching (fixing) the cup-shaped cover 70 to the bolted tip member 40.

The waterproof base member 50 extrapolated to the main column portion 32 of the main column member 30 and placed on the outer layer 5 is a boundary portion between the contact portion 52c and the outer layer 5 surface located around the corresponding contact portion 52c. Formation of the cover waterproof layer 61 covering 52d functions to prevent water from entering the cover portion 52b (inner surface side), particularly to the construction hole 5c, and to ensure waterproofness.
The outer layer 5 illustrated in FIG. 13 has a waterproof layer 5b (existing waterproof layer) that forms the surface thereof, and the cover waterproof layer 61 is located on the contact portion 52c of the waterproof base member 50 and its periphery. It suffices to form a ring that covers the boundary with the surface of the outer layer 5. However, the cover waterproof layer 61 may cover the surface of the outer layer 5 located around the contact portion 52c of the waterproof base member 50 over a wide range.

In addition, as an outer side layer, although it has the waterproof layer 5b (existing waterproof layer) which forms the surface (upper surface), the structure which does not have a heat insulating material layer may be sufficient.
Further, the outer layer is not limited to the configuration having the waterproof layer 5b that forms the surface (upper surface), and the surface may be formed by a layer other than the waterproof layer such as a heat insulating material layer. . In this case, for example, the waterproof layer itself that covers the surface of the outer layer 5 located around the contact portion 52c of the waterproof base member 50 that is extrapolated to the main pillar portion 32 and is in contact with the outer layer surface is waterproofed. A cover waterproof layer that extends to the outer surface of the base member 50 and covers a boundary portion between the contact portion 52c and the outer layer surface around the contact portion 52c.

For this reason, the foundation anchor 10 receives a load acting in the rotational direction around the boundary portion between the portion embedded in the concrete base material 3 and the portion protruding from the concrete base material 3 in the anchoring anchor 20. The proximal end side contact portion 31 of the member 30 and the anchoring anchor 20 are distributed and exert a resistance force. Therefore, the foundation anchor 10 can ensure high shear strength (shear strength) and can stably support a large installation 2 such as a photovoltaic power generation panel or a solar water heater.

  In addition, the bolted tip member 40 to which the installation object 2 is attached can be adjusted in position in the axial direction with respect to the main column member 30 (height adjustment is possible). Height adjustment is easy. For this reason, it is easy to respond | correspond to the magnitude | size and shape of the installation thing 2, and a desired support position, and it can be made versatile. After the waterproof layer 60 is formed on the waterproof base member 50, the foundation anchor 10 can perform an operation of adjusting and fixing the bolted tip member 40 in the axial direction with respect to the main column member 30.

It is possible to adjust the height of the installation object 2 by adjustment (height adjustment with respect to the base 3).
For example, as shown in FIG. 1, the support frame 4 is externally inserted into a bolt portion 43 of a bolted tip member 40 that is passed through a bolt insertion hole 4 b formed in the support frame 4, and the top plate portion of the cup-shaped cover 70. It can be fixed to the bolted tip member 40 by abutting against 70a. In this case, since the distance from the base portion of the fixing position of the support frame 4 to the bolted tip member 40 can be very short, it is advantageous in terms of securing strength against the shear load acting from the installation 2, and the bolt The height of the installation object 2 can be adjusted by adjusting the position of the main column member 30 of the attached tip member 40 in the axial direction (height adjustment with respect to the base 3).

The base portion composed of the main column member 30 and the mounting portion 42 of the bolted tip member 40 fixes the main column member 30 to the concrete base material 3 using the fixing anchor 20, and the bolted tip is attached to the main column member 30. The member 40 can be easily assembled simply by fixing it with the fixing screw 41. In addition, the foundation anchor 10, after assembling the foundation portion, is waterproofed to the waterproof base member 50 that is extrapolated to the main pillar member 30 and brought into contact with the base 3 (the outer layer 5 in FIG. 13). , 61 (waterproof cover layer), waterproof treatment such as installation of the sealing material 55, and attachment work of the cup-shaped cover 70 can be performed efficiently. For this reason, this foundation anchor 10 can ensure high construction workability, and can shorten a work period.
The foundation part which consists of the main pillar member 30 and the attaching part 42 of the tip member 40 with a bolt can implement | achieve significant weight reduction and cost reduction compared with the conventional concrete foundation block.

A screw hole 51 a is formed in which a set screw 56 for fixing to the main pillar portion 32 is screwed.
The waterproof base member 50 </ b> A includes the set screw 56 that is screwed into the screw hole 51 a that penetrates the cylindrical portion 51 in the thickness direction in a state where the waterproof base member 50 </ b> A is extrapolated to the main column portion 32 of the main column member 30. The main column member 30 is fixed to the main column portion 32 by being screwed from the outside 51 and pressing the main column portion 32 of the main column member 30 with the tip of the set screw 56. Such a set screw 56 functions as a waterproof base fixing member that fixes the waterproof base member 50 </ b> A to the main column portion 32 of the main column member 30.

  In assembling (constructing) the foundation anchor 10A for the construction target structure having the structure in which the outer layer 5 is provided on the ground 3 (concrete base material), the waterproof base member 50A is fixed to the base end side using the anchor 20 for fixing. The contact portion 31 is fixed to the base 3 and the main column member 30 erected on the base 3 is extrapolated from the tip thereof so that the waterproof overhang 57b of the waterproof base body 52 is brought into contact with the outer layer 5 and screw holes It is fixed to the main pillar member 30 by tightening a set screw 56 that is screwed into 51a. The fixing position of the waterproof base member 50A in the axial direction (height direction) with respect to the main column member 30 is determined by the thickness of the outer layer 5 laminated on the base 3 (for example, the solid line position and the chain line position in FIG. 14).

  An O-ring 54 fitted in a groove 51b formed on the inner surface of the tubular portion 51 is provided inside the tubular portion 51. The O-ring 54 is in close contact with the outer peripheral surface of the main column portion 32, The waterproofness between the shape part 15 and the main pillar part 32 of the main pillar member 30 can be improved.

  As shown in FIG. 14, in the construction target structure that is the construction target of the foundation anchor 10 </ b> A, the thickness of the outer layer 5 is the same as the overhanging portion of the base portion 33 of the proximal end contact portion 31 of the main column member 30. Or a big thing can be employ | adopted. Also, a construction hole 5c that is recessed from the base surface 3a is formed, and the proximal end contact portion 31 is accommodated in the construction hole 5c, and the projecting portion of the proximal end contact portion 31 is used as the outer layer 5. It is also possible to arrange it from the surface to the base 3 side or the outer layer 5 surface.

  The waterproof overhanging portion 57b of the waterproof base member 50A is formed in a plate shape projecting perpendicularly in the axial direction of the outer insertion cylinder portion 53 from the entire circumference of one end in the axial direction of the outer insertion cylinder portion 53 to the outer periphery thereof. Yes. For this reason, the waterproof overhanging portion 57b of the waterproof base member 50A extrapolated to the main column portion 32 of the main column member 30 erected on the base 3 is the surface of the construction target structure (in the illustrated example, the heat insulating waterproof layer 5). A flat surface extending along the surface of the construction target structure is formed. Therefore, the foundation anchor 10A can secure a flat scaffold (worker's scaffold) around the support member 30 after the construction of the cover waterproof layer 61. As a result, after the construction of the cover waterproof layer 61, the sealing member 55 seals the gap between the upper end of the extrapolated tube portion 53 (upper end of the tubular portion 51) of the waterproof base member 50A and the outer peripheral surface of the support member 30, and the support member. The workability of the work performed in the vicinity of the column member 30 such as the screwing and fixing of the bolted tip member 40 to the 30 can be ensured satisfactorily.

In the construction of the foundation anchor 10A to the construction target structure, the end of the cover waterproof layer 61 formed on the outer side surface of the waterproof base member 50A (the surface of the overhang portion 57b of the waterproof and the extrapolated cylinder portion 53). Is waterproofed using a sealing material 55.
Further, the screw hole 51a into which the set screw 56 for fixing the waterproof base member 50A to the main column portion 32 of the main column member 30 is screwed is waterproofed using the cover waterproof layer 61 or a sealing material.

The position adjustment of the bolted tip member 40 in the axial direction with respect to the column member 30 is performed by rotating the bolted tip member 40 about the axis and attaching the bolt to the upper internal threaded portion 38a of the main column portion 32 of the main column member 30. This is realized by adjusting the screwing length of the attachment portion 42 of the tip member 40.
When the position adjustment of the bolted tip member 40 and the fixing by tightening the fixing nut 48 are completed, the cup-shaped cover 70 is attached to the bolted tip member 40.

  As shown in FIG. 14, the cup-shaped cover 70 has a front end surface 42a of the mounting portion 42 in the bolted tip member 40 by inserting the bolt portion 43 of the bolted tip member 40 into the bolt hole 71 of the top plate portion 70a. It is attached in a state in contact with In this attached state, the cup-shaped cover 70 is from the tip (the tip of the mounting portion 42 of the bolted tip member 40) of the base portion formed by fixing the mounting portion 42 of the bolted tip member 40 to the main column member 30. The range including the fixing position of the fixing nut 48 is covered. Thus, the cup-shaped cover 70 prevents water from entering from the boundary between the leading end of the main column portion 32 and the portion extending from the leading end of the main column portion 32 of the mounting portion 42 of the bolted tip member 40.

(Third embodiment)
FIG. 24 shows a foundation post-installation anchor (foundation anchor) 10B according to a third embodiment of the present invention. In the description, the upper side is the upper side and the lower side is the lower side.
The foundation anchor 10 </ b> B of this embodiment includes a main column member 30 that is fixedly installed on the foundation 3 (concrete base material), and a fixing anchor 20 for fixing the main column member 30 to the concrete base material 3. A waterproof base member 50B and a waterproof layer cover 63 that are extrapolated to the main column portion 32 extending from the base end side contact portion 31 that is in contact with the base 3 of the main column member 30, and the main column member 30 And a bolted tip member 40 fixed to the tip of the column part 32. The foundation anchor 10B also has a cup-shaped cover 70 attached to the bolted tip member 40.

The foundation anchor 10B employs a main column member 30 (main column member 30A) in which an external thread portion 32e is formed on the outer periphery of the main column portion 32, and is screwed to the main column portion 32 as a tip member 40 with a bolt. Thus, a cylindrical mounting portion 42 that accommodates the main column portion 32 is employed.
Reference numeral 32A in the figure is added to the main pillar portion 32, reference numeral 40A is attached to the tip member 40 with bolt, and reference numeral 42A is attached to the mounting portion 42.

The main column member 30A in the illustrated example employs a configuration in which the base end side contact portion 31 and the main column portion 32 are integrally formed of metal.
The base end side contact portion 31 of the main column member 30A is one end portion in the direction of the central axis of the main column member 30A (corresponding to the central axis of the main column portion 32), and protrudes in a flange shape on the outer periphery of the main column member 30A. Including an overhanging portion 31a. The main pillar member 30A fixes a plurality of portions of the protruding portion 31a of the base end side abutting portion 31 abutted against the ground surface of the construction target structure to the ground 3 using the fixing anchor 20, 3 is erected. The anchor 20 for fixing is inserted into the anchor hole 31b penetrating at a plurality of locations of the projecting portion 31a in the circumferential direction of the main column member 30A with an axis parallel to the central axis of the main column member 30A, and is attached to the base 3 It is fixed.

The main column portion 32A of the main column member 30A is formed by a large-diameter portion 32c located on the proximal end side contact portion 31 side and a small-diameter portion 32d on the distal end side. The external thread portion 32e of the main column portion 32 is formed on the outer peripheral surface of the small diameter portion 32d.
Note that the main pillar member 30A of the foundation anchor 10B in the illustrated example is a solid metal member as a whole, and the main pillar part 32A has a solid metal rod shape (specifically, a solid cylindrical shape). Is formed.
However, as the main column member 30A, a cylindrical member having a through-hole extending along the central axis can be employed.
Further, the main column portion 32A is not necessarily limited to the configuration having the large diameter portion 32c and the small diameter portion 32d, and may have a configuration in which the outer diameter is constant over the entire length in the axial direction. The external thread portion 32e on the outer periphery of the main column portion 32A only needs to be formed at least at the tip of the main column portion 32, and may be formed over the entire axial length of the main column portion 32A. However, the waterproof base member 50B and the waterproof layer cover 63 provided below the attachment portion 42A of the bolted tip member 40A screwed to the main column portion 32A facilitates waterproofing between the outer peripheral surface of the main column portion 32A. Thus, the main column portion 32A secures a region in which the male screw portion 32e is not formed on the proximal end side of the region in which the male screw portion 32e is formed (unthreaded outer peripheral surface) in the entire axial direction length. It is preferable that the surface be an attachment portion for the main column portion 32A of the waterproof base member 50B and the waterproof layer cover 63.

The mounting portion 42A of the bolted tip member 40A includes a screwed tube portion 42d having an inner peripheral surface formed with a female screw portion 42e that is screwed into the male screw portion 32e on the outer periphery of the small diameter portion 32d of the main column portion 32, and the screwed tube. It is comprised in the bottomed cylindrical shape which has the top-plate part 42c which plugs up the axial direction one end of the part 42d. The top plate portion 42c of the mounting portion 42 in the illustrated example is provided through the central portion of the end plate portion 42b projecting from one end in the axial direction of the screwed tube portion 42d to the inner peripheral side along the axial direction of the screwed tube portion 42d. The female screw hole 42c thus formed is closed by an end portion of a bolt portion 43 that is screwed into the female screw hole 42c and fixed to the end plate portion 42b. This bolted tip member 40A has a female threaded portion 42e inside the threaded tube portion 42d of the mounting portion 42A, from the opening end side of the threaded tube portion 42d opposite to the top plate portion 42c, of the main column member 30A. The main pillar portion 32 can be screwed onto the small diameter portion 32d by being screwed into the male screw portion 32e on the outer periphery of the small diameter portion 32d.
Note that the mounting portion 42 and the bolt portion 43 of the bolted tip member 40 of the embodiment according to the present invention are made of metal, respectively, and this is about the mounting portion 42A and the bolt 43 of the bolted tip member 40A of this embodiment. Is the same.

The bolt part 43 of the bolted tip member 40A protrudes from the top plate part 42c to the side opposite to the opening end of the attachment part 42A (specifically, the screwed cylinder part 42d).
Further, the female screw hole 42c of the top plate portion 42c is secured to water resistance by, for example, application of a sealing material (not shown).
Note that the bolted tip member 40A may be a metal member in which the bolt portion 43 is integrally formed with the mounting portion 42A.

The bolted tip member 40A is adjusted by adjusting the screwing length (screwing length) of the mounting portion 42A (specifically, the screwed tube portion 42d) to the small diameter portion 32d of the main column portion 32 of the main column member 30A. The position (height position) in the axial direction with respect to the main column member 30A can be adjusted.
Further, a fixing screw hole 42f, which is a female screw hole penetrating the wall thickness, is formed in the central portion in the axial direction of the attachment portion 42A of the tip member 40A with bolt. In the bolted tip member 40A, the mounting portion 42A is screwed into the small diameter portion 32d of the main column portion 32 of the main column member 30A, and the fixing screw 42g screwed into the fixing screw hole 42f is fixed from the outside of the mounting portion 42. It is fixed to the main pillar portion 32A by screwing into the inner side of the screw hole 42f (inside the attachment portion 42) and pressing the small diameter portion 32d inside the attachment portion 42. Thereby, the base part formed by fixing the attachment portion 42A of the bolted tip member 40A to the main pillar member 30A is assembled.

The foundation anchor 10B functions as a cylindrical portion in which the mounting portion 42A of the bolted tip member 40A can accommodate the main column portion 32A of the main column member 30A. In such a structure, the attachment portion 42A of the bolted tip member 40A covers the small diameter portion 32d of the main column portion 32A. For this reason, in the foundation anchor 10B (anchor assembly) that has been assembled, for example, water that has flowed down the outer peripheral surface of the mounting portion 42A of the bolted tip member 40A is removed from the mounting portion 42A (specifically, a screwed cylinder). Part 42d) flows from the boundary 42h between the opening end (the lower end in FIG. 24) and the outer peripheral surface of the main column 32A along the outer peripheral surface of the main column 32A, and the inundation from the boundary 42h occurs. Absent. The anchor assembly in which the foundation anchor 10B is assembled is submerged in water on the inner surface side of a waterproof base member 50B, which will be described later, provided by extrapolation from the boundary portion 42h to the large diameter portion 32c of the main column portion 32A. There is no worry that will occur.
Therefore, in the foundation anchor 10B, waterproofing processing such as providing a sealing material at the boundary portion 42h can be omitted or simplified. Further, even if the cup-shaped cover 70 is omitted, the foundation-shaped anchor 10B has a small influence on securing waterproofness, and therefore the cup-shaped cover 70 can be omitted.
As described above, the foundation anchor 10B can reduce the number of places for waterproofing and can reduce the trouble of waterproofing in the assembling work. Therefore, there is an advantage that the working time for assembling the construction target structure can be shortened.

The cup-shaped cover 70 prevents deterioration of the constituent members of the anchor assembly (particularly deterioration of a sealing member such as an O-ring) due to exposure of the anchor assembly to direct sunlight, and the waterproof performance of the seal portion. Contributes effectively to the realization of long-term stable maintenance.
The same applies to the foundation anchors and anchor assemblies of other embodiments according to the present invention.

The waterproof base member 50B of the foundation anchor 10B in the illustrated example is obtained by attaching a waterproof base body 58 having a cover portion 52b capable of accommodating the proximal end side contact portion 31 of the column member 30A to a cylindrical tubular portion 51.

The tip ring portion 52a, the cover portion 52b, and the contact portion 52c are arranged coaxially. Further, the cylindrical plate portion 52b2 and the contact portion 52c of the cover portion 52b are provided on the opposite side of the tip ring portion 52a via the ring plate portion 52b1 in the central axis direction of the waterproof base body 58.

Then, as shown in FIG. 24, the waterproof base member 50B is waterproofed from one end in the axial direction of the extrapolated tube portion 53 formed by attaching the tip ring portion 52a of the waterproof base body 58 to the tubular portion 51 and integrating them. The waterproof overhang 50a, which is a portion other than the tip ring portion 52a of the base body 58, is overhanging. The outer insertion cylinder part 53 is formed to be able to be extrapolated to the large diameter part 32c of the main pillar part 32A, and the waterproof base member 50B can be entirely extrapolated to the large diameter part 32c of the main pillar part 32A. The waterproof base member 50B is provided by extrapolating the extrapolated cylinder portion 53 to the large-diameter portion 32c of the main pillar portion 32A and bringing the abutment portion 52c into contact with the surface of the construction target structure.
The constituent member of the waterproof base member 50B is not limited to a metal member, and may be a plastic member.

The waterproof layer cover 63 of the foundation anchor 10B of the illustrated example is formed in a generally cup shape that is extrapolated to the large-diameter portion 32c of the main pillar portion 32A and accommodates the outer insertion cylinder portion 53 and the cover portion 52b of the waterproof base member 50B.

The waterproof layer cover 63 includes a cylindrical tip ring portion 63a that can be extrapolated to the large diameter portion 32c of the main column portion 32A, and a flange that projects from the entire circumference of one end in the axial direction of the tip ring portion 63a to the outer peripheral side. 63d and a cover portion 63b composed of a cylindrical side plate portion 63g raised vertically to the entire outer periphery of the top plate portion 63d, and the top plate of the cylindrical side plate portion 63g of the cover portion 63b It has a plate-like pressing part 63c protruding from the end opposite to the part 63d over the entire outer periphery thereof. The waterproof layer cover 63 is a cover waterproof layer that covers the contact portion 52c of the waterproof base member 50B with the open end of the substantially cup-shaped cover portion 63 in a state of being extrapolated to the large diameter portion 32c of the main column portion 32A. By abutting, the end of the cover waterproof layer is accommodated and the function of keeping waterproof is achieved.
The waterproof layer cover 63 is formed by screwing a tip ring portion 63a inserted inside the fixing ring 86 that is inserted outside the large-diameter portion 32c of the main column portion 32A into a female screw hole that penetrates the thickness of the fixing ring 86. It is fixed to the main column portion 32A by being pressed against the main column portion 32A by the combined fixing screw 87. As a result, the waterproof layer cover 63 can maintain a state in which the pressing portion 63 c at the open end of the cover portion 63 is in close contact with the cover waterproof layer 61, and the cover portion 63 is interposed between the cover portion 63 and the cover waterproof layer 61. Inundation to the inside can be prevented.

  Further, the space between the fixing ring 86 and the outer peripheral surface of the main column portion 32A is sealed in a water-tight manner by the O-ring 54 provided inside the fixing ring 86, so that water does not enter. For this reason, the waterproofness inside the cover part 63 is reliably maintained. Therefore, the waterproofing process of the edge part of the cover waterproof layer formed in the outer surface of the waterproof base member can be omitted.
