The insertion portion 14 for inserting the spiral portion 22 is formed.
In the following, description will be given mainly using standing objects such as poles and fence posts as examples of structures.

In FIG. 1, the example of the 1st metal fitting 10 in the metal fitting for support which concerns on this invention is shown, (a) is a front view, (b) is a side view, (c) is a top view.
The first metal fitting 10 includes a cylindrical main body portion 11 which is a cylindrical steel pipe having an inner diameter into which at least the spiral portion 22 can be inserted, and two metal rod-like members 12 are arranged in the radial direction on one (upper) opening side. Are arranged parallel to each other, and one metal rod-like member 13 is arranged along the radial direction on the other (lower) opening side. In addition, in FIG.1 (c), the rod-shaped member 13 is abbreviate | omitted.
The two rod-like members 12 on the upper opening side are arranged at an interval of at least the thickness of the spiral portion 22, thereby forming a slit-shaped insertion portion 14 through which the spiral portion 22 can pass while rotating. ing.
One rod-like member 13 on the lower opening side is for lower joining. That is, it has a role of a fixing portion when the cylindrical main body portion 11 is embedded and fixed in the foundation, and the rod-like member 13 is buried with an adhesive or cement in the cylindrical main body portion 11 embedded in the foundation. The first metal fitting 10 can be firmly fixed to the foundation by filling and fixing until it is done. In addition, the member for lower joining is arbitrary, For example, the several rod-shaped member 13 may be provided, or the member (for example, board | plate material) of another shape may be provided.

In FIG. 2, the example of the 2nd metal fitting 20 in the metal fitting for support which concerns on this invention is shown, (a) is a front view, (b) is a top view, (c) is a bottom view.
The second metal fitting 20 can be inserted with a disc-shaped lid member 21 covering the opening of the first metal fitting 10, a spiral part 22 formed by twisting flat steel, and at least the lower tip of the standing object to be supported. And a structure mounting portion 23 that is a cylindrical steel pipe having an inner diameter.
The spiral portion 22 is provided on the spiral portion 21 on one surface (lower surface) of the lid member 21, and the structure attachment portion 23 is provided on the other surface (upper surface).

The support metal fitting of this example can be constructed according to the procedure shown in FIG.
First, as shown to Fig.3 (a), the hole which has an internal diameter which can accommodate the 1st metal fitting 10 is made perpendicularly | vertically in the foundation which provides a standing structure. As the foundation, asphalt, concrete, mortar, stone, wood, and the like can be used, but it is necessary to have strength capable of supporting a standing object.

  Next, as shown in FIG. 3 (b), the first metal fitting 10 is accommodated and embedded in a hole provided in the foundation with the insertion portion 14 facing upward, and the first metal fitting 10 is attached with an adhesive or cement. Secure to the foundation. At this time, in addition to filling an adhesive, cement, or the like between the inner peripheral surface of the hole provided in the foundation and the outer peripheral surface of the first metal fitting 10 embedded in the hole, a rod-shaped member is also provided inside the first metal fitting 10. By filling until 13 is buried, the first metal fitting 10 is firmly fixed to the foundation. The first metal fitting 10 may be fixed at least partially embedded in the foundation, but the first metal fitting 10 can be firmly fixed to the foundation as the degree of embedding of the first metal fitting 10 increases.

Next, as shown in FIG. 3C, the tip of the spiral portion 22 of the second metal fitting 20 is inserted into the insertion portion 14 on the upper opening side of the first metal fitting 10, and the second metal fitting 20 is pushed in while rotating. Go (screw). Thereby, the 2nd metal fitting 20 is engage | inserted by the 1st metal fitting 10, and the whole metal fitting for support is fixed to a foundation.
Thereafter, the lower end portion of the standing object to be supported is inserted and attached to the structure attachment portion 23 of the second metal fitting 20. Accordingly, the standing object is supported on the foundation by the support metal fitting, and the standing object can be erected on the foundation.

  Thus, according to the support metal fitting of this example, at least a part of the first metal fitting 10 is embedded in the foundation, the spiral portion 22 of the second metal fitting 20 is inserted into the insertion portion 14 of the first metal fitting 10, and the second By simply attaching a standing object to the metal fitting 22, it is possible to stand on the basis of a standing object such as a pole or a fence post. In addition, since this support metal fitting has a simple structure, it can be manufactured at a lower cost than a concrete support foundation. For this reason, by using the support metal fitting of this example, it is possible to stand the standing object on the foundation at a lower cost than in the case of using the concrete support foundation.

  Further, in the support metal fitting of the present example, the first metal fitting 10 has the slit-shaped insertion portion 14 through which the spiral portion 22 of the second metal fitting 20 can pass while rotating. In order to attach to the metal fitting 10, it is only necessary to insert the tip of the spiral portion 22 of the second metal fitting 20 into the insertion portion 14 of the first metal fitting 10 and push in (screw) the second metal fitting 22 while rotating it. Further, in order to remove the second metal fitting 20 from the first metal fitting 10, it is necessary to pull out the second metal fitting 20 while rotating the second metal fitting 20 in the direction opposite to the time of attachment (when screwing). It can suppress that the 2nd metal fitting 20 remove | deviates from 10. FIG.

  Moreover, the support metal fitting of this example forms the slit-shaped insertion part 14 by the two rod-shaped members 12 arranged in parallel along the radial direction of the cylindrical main body part 11 of the first metal fitting 10. By forming the slit shape with a simple structure as described above, the component cost is suppressed. Further, since there is a sufficient gap on the outer side of the two rod-shaped members 12 on the upper opening side of the cylindrical main body 11, it is easy to clean the inside through this gap. Note that the insertion portion 14 may be formed by providing an additional rod-like member, a plate-like member, or the like.

  In addition, the insertion part 14 provided in the 1st metal fitting 10 can also be implement | achieved by the structure which does not use the rod-shaped member 12. FIG. FIG. 4 shows another example of the first metal fitting 10, wherein (a) is a side sectional view and (b) is a plan view. In the example of FIG. 4, two plate-like members 15 are arranged on the same plane on the upper opening side of the first metal fitting 10 with an interval of at least the thickness of the spiral portion 22, thereby A slit-shaped insertion portion 14 through which 22 can pass while rotating is formed. Moreover, in the example of FIG. 4, the display of the member for lower joining is abbreviate | omitted, but the direction which provided the member for lower joining can fix to a foundation more firmly.

Further, the first metal fitting 10 in the support metal fitting of the present example includes a cylindrical main body portion 11, and a spiral portion 22 of the second metal fitting 20 is formed so as to be insertable along the central axis. As a result, the edge portion of the spiral portion 22 faces spirally with respect to the inner peripheral surface of the cylindrical main body portion 11, so that the force to incline the second metal fitting 20 with respect to the first metal fitting 10. Can be obtained in any direction.
In this example, the cylindrical main body portion 11 made of a cylindrical steel pipe is used. A cylindrical main body 17 made of a square steel pipe having a hexagonal cross section as shown in FIG. 7B can also be used. When such a square steel pipe is used as the cylindrical main body portion, the attachment surfaces of the rod-like members 12 and 13 are not curved surfaces such as cylindrical steel pipes, but are flat, so that the rod-like members 12 and 13 are provided on the square steel pipe. Therefore, the process of providing a hole for mounting and the work of attaching and welding the rod-shaped members 12 and 13 to the hole are facilitated.
As another example of the first metal fitting 10, as shown in FIG. 7C, a slit-shaped insertion portion 14 may be provided on one side surface of a cylindrical main body portion 18 made of a rectangular square steel pipe. . In this case, what is necessary is just to embed the 1st metal fitting 10 in the foundation in the horizontal direction instead of the vertical direction (axial direction) of the cylindrical main-body part 18.

  In addition, the second metal fitting 20 in the support metal fitting of this example includes a lid member 21 that covers the upper opening of the first metal fitting 10 into which the spiral part 22 is inserted on the base side of the spiral part 22. Due to the presence of the lid member 21, it is possible to prevent dirt and dust from entering the space inside the first metal fitting 10 and getting dirty.

  Further, in the second metal fitting 20 in the support metal fitting of this example, the length of the spiral portion 22 is set to 0.5λ on the basis of the length λ by which the flat steel is twisted once. The spiral portion 22 may have other lengths, but is preferably 0.5λ or more in order to prevent a situation in which the second fitting is detached from the first fitting. Further, when the spiral part 22 becomes longer, the cost of parts and the inconvenience of handling occur, so it is preferable to keep the length of the spiral part 22 to 2λ or less.

  In addition, since the support bracket of this example is assumed to be erected on the basis of an erected object such as a pole or a fence post, the lower end of the erected part is inserted into the structure attachment part 23. The second metal fitting 20 having the structure mounting portion 23 having an inner diameter of about 5 cm is used so that the structure mounting portion 23 has a smaller inner diameter (for example, about 2 cm). Can also be used. A plurality of second metal fittings 20 having different inner diameters of the structure attachment portion 23 are prepared, and the second metal fitting 20 attached to the first metal fitting 10 is changed according to the application (object to be erected). Also good.

  Further, the second metal fitting 20 is replaced with the cylindrical structure attachment portion 23 as described above, and a structure provided with a structure attachment portion of another shape is used, so that standing objects such as poles and fence posts are provided. In addition, other structures can be supported on the basis.

  For example, if the second metal fitting 20 provided with the male screw-shaped structure attachment portion 25 shown in FIG. 5A is used, a holder provided with a corresponding female screw portion is attached to the structure attachment portion 25, A structure can be attached to the second metal fitting 20 via the holder, or a structure provided with a female screw portion can be directly attached to the second metal fitting 20. In this case, not only the form in which the first metal fitting 10 is vertically buried in the horizontal foundation, the form in which the first metal fitting 10 is obliquely buried in the horizontal foundation, and the form in which the first metal fitting 10 is vertically or obliquely buried in the vertical foundation. It is possible to support various structures on the foundation in an arbitrary posture.

  Further, for example, when the second metal fitting 20 provided with the ring-shaped structure mounting portion 26 shown in FIG. 5B or the knob-shaped structure mounting portion 27 shown in FIG. 5C is used. If the first metal fitting 10 is buried vertically or obliquely on the vertical foundation and the second metal fitting 20 is fitted, various wires can be obtained by hooking the wire or hook connected to the structure to the second metal fitting 20. It becomes possible to support the structure on the basis.

FIG. 6 shows an example of a third metal fitting 30 that can be attached to the first metal fitting 10 in place of the second metal fitting 20.
The third metal fitting 30 includes a disk-shaped lid member 31 that covers the opening of the first metal fitting 10 and a spiral portion 32 formed by twisting flat steel. However, unlike the 2nd metal fitting 20, the structure attachment part for attaching a structure is not provided. The third metal fitting 30 is to be fitted to the first metal fitting instead of the second metal fitting 20 when the already installed support metal fitting is not used, so that the presence of the constructed support metal fitting does not get in the way. It becomes like this.

  By using the support metal fitting according to the present invention, it becomes possible to support various structures on the basis.
