The present invention is a strut structure that supports and supports a mesh fence (fence portion), which is an accessory 4 that forms a mesh with a vertical rail 41 and a horizontal rail 42. This strut structure is fitted to the one-piece type strut structure 1 or the base pile 21 (driving pile) and the upper end side of the base pile 21, and supports the fence portion (attachment 4). It is divided into a two-piece type strut structure 2 having a strut member 3 to be formed.

Hereinafter, the one-piece type strut structure 1 and the two-piece type strut structure 2 will be described, and other constituent articles will also be described.

The one-piece type strut structure 1 is literally a one-piece strut structure, and its constituent articles are mainly a strut pile 11, an end cap 17, and a fence where it is an adjunct 4. Department etc. can be mentioned.

As shown in FIG. 1, the pillar pile 11 is divided into a pile head 13, a main body 14, and a tip 15. The pile head 13 is the head portion of the pillar pile 11 of the one-piece type pillar structure 1. In other words, when the pillar pile 11 penetrates into the underground G1, the upper side (top side) becomes the pile head 13. Further, the tip portion 15 is on the opposite side (ground side) of the pile head 13, and the tip portion 15 has an acute angle, and the tip portion 15 penetrates into the underground G1 from the acute angle tip portion 15.

As one of the features of the present invention, a hit portion 16 having a diameter smaller than the outer diameter of the main body portion 14 and the pile head 13 is projected from the pile head 13. The hit portion 16 is a portion to be driven when the support pile 11 is penetrated into the underground G1. By hitting the hit portion 16 with an automatic hammer, a hand hammer, or the like, the support pile 11 is gradually brought into the underground G1. Can be penetrated.

The hit portion 16 may have a diameter smaller than the outer diameter of the main body portion 14 and the pile head 13, and the diameter may not be limited. Further, it suffices as long as it protrudes from the pile head 13, and the length of the protrusion does not matter. That is, the size of the diameter of the hit portion 16 and the protruding length can be appropriately selected.

Regarding the hit portion 16, it is conceivable that the hit portion 16 is welded and fixed to the pile head 13 at the upper end of the main body portion 14. Specifically, a connecting member (not shown) is welded (built-up welding) to the connection portion between the pile head 13 and the hit portion 16. As the connecting member, for example, weld metal, metal powder, or the like can be considered, but any material may be used as long as the pile head 13 and the hit portion 16 can be connected.

For example, when the support pile 11 has a tubular shape (steel pipe) as shown in FIG. 3A, a part of the hit portion 16 having a diameter smaller than the inner diameter of the support pile 11 is inserted from the upper end of the support pile 11 to support the support. A connecting member is welded to the connection point between the upper end of the pile 11 (pile head 13) and the hit portion 16. When the support pile 11 is columnar (not shown), a hit portion 16 having a diameter smaller than the outer diameter of the support pile 11 is placed on the pile head 13 at the upper end of the support pile 11, and the upper end of the support pile 11 is placed. A connecting member is welded to the connection point between the (pile head 13) and the hit portion 16.

In addition, the hit portion 16 may be formed by shaving from the main body portion 14. It can also be integrally molded by casting.

When the pile head 13 of the pillar pile 11 is driven to penetrate the underground G1, the pile head 13 is crushed by a blow with a hammer or the like, and the crushed portion is on the outside (support pile). It may be difficult to attach an end cap 17 or the like having an inner diameter substantially the same as the outer diameter of the support pile 11 by projecting to the outside (outside the outer diameter of 11). According to the present invention, since the pile head 13 is not driven but the hit portion 16 is driven, an end cap 17 or the like having an inner diameter substantially the same as the outer diameter of the support pile 11 can be attached.

As described above, the tip portion 15 has an acute angle so as to penetrate into the underground G1. The tip portion 15 may be a separate member from the main body portion 14, or may be integrated with the main body portion 14 as shown in FIG.

When the tip portion 15 is a separate member from the main body portion 14, it is desirable that the material is harder than the main body portion 14. For example, chrome steel (SCr420 charcoal-burned steel, etc.) can be mentioned. If the tip portion 15 is made of a material harder than the main body portion 14, it can be more easily and more reliably penetrated into the underground G1.

It is conceivable that the tip portion 15 which is a separate member from the main body portion 14 is welded and fixed to the lower end of the main body portion 14. Specifically, the connecting member is welded (build-up welding) to the connection portion between the lower end portion of the main body portion 14 and the tip portion 15. As the connecting member, for example, weld metal, metal powder, or the like can be considered, but any material may be used as long as the main body portion 14 and the tip portion 15 can be connected.

The tip portion 15 can be integrally formed with the main body portion 14 by shaving from the main body portion 14. In addition, it can also be integrally molded by casting.

Further, the tip portion 15 can be formed by forging, and according to this forging, more strength can be secured.

The main body portion 14 is a portion that becomes the main body of the one-piece type support column structure 1, and an attachment 4 (fence portion) is attached to the main body portion 14. For this reason, the main body portion 14 is provided with a fixing hole 14b for fixing the accessory in a penetrating state. The installation position of the fixing hole 14b does not matter. Any position may be used as long as a fence portion forming a mesh can be attached to the vertical rail 41 and the horizontal rail 42. In addition, it is desirable that two or three places are drilled at a certain interval.

Examples of the main body portion 14 include steel materials and steel pipes, but steel pipes are desirable in order to reduce weight and the like. Further, the cross section of the main body portion 14 is considered to be circular, polygonal or the like. Therefore, a cylindrical shape, a cylindrical shape, a polygonal cylinder shape, a polygonal columnar shape, or the like can be appropriately selected and used, but from the viewpoint of weight reduction, the cylindrical shape or the polygonal cylinder shape is more preferable. Examples of the polygon include a quadrangle as shown in FIG. 3B, a triangle, a pentagon, a hexagon, a heptagon, an octagon, and the like.

Further, for example, when the support pile 11 has a tubular shape as shown in FIG. 3, a drainage hole 14c for draining rainwater that has entered the inside of the main body 14 from the fixing hole 14b to the underground side is formed in a penetrating shape. There is. Since the diameter, number, position, etc. of the drainage holes 14c are not limited, any diameter, number, and position may be used, but the position of the drainage holes 14c is formed below the main body 14. desirable.

Examples of the material include inexpensive and highly durable materials such as SS400 material, which is relatively soft, but other materials may be used.

The length, diameter, color, and surface treatment may be any. As for the surface treatment, it is conceivable to perform powder coating after pre-plating. Then, the attachment and fixing of the attachment 4 (fence portion) to the main body 14 is performed as follows via the attachment fixture 5 such as a U-shaped hook bolt or nut.

First, with the fence portion attached to the main body portion 14 (attachment surface 14a) of the support pile 11, a hook bolt having a screw groove screwed in the leg portion is inserted into a fixing hole of the main body portion of the support pile 11. The hook bolt is inserted into the fixing hole 14b from the fence portion side.

Then, the horizontal rail (or vertical rail) of the fence portion is hooked by the hook portion of the hook bolt, and the nut is screwed into the screw groove of the hook bolt in this state. As a result, the attachment 4 (fence portion) is attached and fixed to the main body portion 14 of the support pile 11.

It is conceivable that the support pile 11 is subjected to a hot-dip galvanizing treatment having a rust preventive property. Further, in order to prevent corrosion due to organic substances contained in the soil, a paint having high corrosion resistance can be applied, or a coating or the like can be applied. Therefore, for example, a paint having high corrosion resistance may be applied to a portion of the pillar pile 11 that penetrates into the underground G1, and a hot-dip galvanizing treatment may be applied to a portion that exits the underground G1.

The fence portion is a grid-like mesh fence composed of a vertical rail 41 and a horizontal rail 42, and the vertical rail 41 and the horizontal rail 42 are combined to form a mesh. Since the wire diameter of the vertical rail 41 and the horizontal rail 42, the size of the mesh, and the like are not limited, any wire diameter and mesh size may be used.

A cap (not shown) made of resin or the like may be provided at the upper end of the fence portion, specifically, at the upper end of the vertical rail 41. As a result, the upper end of the vertical rail 41 can be guarded.

Further, the invasion of small animals can be prevented by providing a U-shape (semicircular side view) as shown in FIG. 6 or an inclination angle as shown in FIG. 10 above the vertical crosspiece 41. Even in this case, a cap made of resin or the like may be provided at the upper end of the vertical rail 41.

When the upper part of the vertical rail 41 is U-shaped, the upper end surface of the vertical rail 41 is at least flush with the surface attached to the main body portion 14 of the vertical rail 41 so that the end cap 17 can be easily attached. It is desirable to have.

An end cap 17 that is crowned to the hit portion 16 and the pile head 13 is provided. The end cap 17 is mainly made of resin and covers the hit portion 16 and the pile head 13.

Since the end cap 17 covers up to the pile head 13, the inner diameter of the end cap 17 needs to be at least substantially the same as the outer diameter of the main body portion 14. Further, when the end cap 17 covers only the hit portion 16, the inner diameter of the end cap 17 is substantially the same as the outer diameter of the hit portion 16 or larger than the outer diameter of the hit portion 16. Must be diameter. It should be noted that any configuration and method may be used for attaching the end cap 17 to the main body 14. For example, the inside of the end cap 17 or the main body portion 14 may be provided with irregularities, and the end caps 17 may be attached to the main body portion 14 by utilizing the irregularities.

The two-piece type strut structure 2 is literally a two-joint strut structure, and the constituent articles mainly include a base pile 21 (driving pile) and a strut member 3, and the base pile 21 and the strut The members 3 are vertically integrated. Examples of other constituent articles include a fence portion, which is an accessory 4.

The base pile 21 is divided into a pile head 23, a main body portion 24, and a tip portion 25, similarly to the pillar pile 11 of the one-piece type pillar structure 1. The pile head 23 is a pile head portion of the two-piece type support column structure 2. In other words, when the two-piece type support column structure 2 is penetrated into the underground G1, the upper side (top side) of the main body portion 24 is the pile head 23. Further, the tip portion 25 is on the opposite side (ground side) of the pile head 23, and the tip portion 25 has an acute angle, and the tip portion 25 penetrates into the underground G1 from the acute angle tip portion 25.

Since the hit portion 26 of the two-piece type strut structure 2 is the same as the hit portion 16 of the one-piece type strut structure 1, the description thereof will be omitted.

Regarding the tip portion 25, since the tip portion 25 of the two-piece type strut structure 2 is the same as the tip portion 15 of the one-piece type strut structure 1, the description thereof will be omitted.

The main body 24 of the two-piece strut structure 2 is different from the main body 14 of the one-piece strut structure 1 in that the attachment 4 (fence portion) is not attached. Since the other points are almost the same as those of the main body 14 of the one-piece support column structure 1, the description thereof will be omitted. Another difference is that the main body 24 is provided with a connecting fixing hole 24b in which a screw groove is screwed, and as described later, the base pile 21 and the strut member 3 are connected via the connecting fixing tool 6. To. Although not shown, the base pile 21 and the support column member 3 may be connected by welded T-groove nuts and bolts without providing the connection fixing hole 24b.

Then, a support column member 3 that supports the fence portion is fitted to the upper end side of the base pile 21.

(Support member)
As described above, in the two-piece type strut structure 2, an adjunct 4 (fence portion) is attached to the strut member 3. Therefore, although the connecting fixing hole 24b for fixing the attachment 4 (fence portion) is bored in the support column member 3 in a penetrating state, the installation position of the connecting fixing hole 24b does not matter. Any position may be used as long as a fence portion forming a mesh can be attached to the vertical rail 41 and the horizontal rail 42. It is desirable that two or three places are drilled at a certain interval. Further, the support column member 3 is provided with a connection fixing hole 3b in which a screw groove is screwed, and the base pile 21 and the support column member 3 are connected via a connection fixture 6.

(Connection)
The strut member 3 is fitted to the upper end side of the base pile 21, and the base pile 21 and the strut member 3 are integrated. However, the base pile 21 and the strut member 3 are integrated so as to cover the base pile 21. By the way, when the strut member 3 is tubular, if the inner diameter of the strut member 3 is larger than the outer diameter of the base pile 21, it can be fitted as it is, but when the strut member 3 is columnar, the base pile 21 can be fitted. It is necessary to provide a part of the space for the stakes to enter.

An end cap 18 (17) to be attached to the upper end of the support member 3 of the two-piece type support structure 2 can also be provided. In particular, when the strut member 3 has a tubular shape, rain or the like enters the inside, so an end cap 18 (17) for sealing the upper end of the strut member 3 is required. Specifically, the end cap 17 that is attached to the pile head 13 of the pillar pile 11 of the one-piece type pillar structure 1 shown in FIG. 4 can be used, and is abbreviated as the outer diameter of the pillar member 3. It can be covered by sealing the upper end of the support column member 3 with an end cap 17 having the same inner diameter. Similarly, when the strut member 3 has a tubular shape, the end cap 18 may have a structure that fits into the pile head 13 (hole) of the strut member 3 as shown in FIG. As for the crowning of the end cap 18 to the main body 14, any configuration and method may be used, which is the same as that of the one-piece type strut structure 1.

The construction method of the two-piece type strut structure 2 will be briefly described.

The base pile 21 is penetrated into the ground at the place where the fence is installed. The base pile 21 is penetrated into the underground G1 mainly by driving the hit portion 26 of the base pile 21 with a hand hammer or an automatic hammer.

After driving the base pile 21, the support member 3 is fitted (joined) on the driven base pile 21. Then, the connecting fixing hole 24b of the main body 24 of the base pile 21 and the connecting fixing hole 3b of the strut member 3 are aligned, and the connecting fixing tool 6 in which the screw groove is screwed into the connecting fixing hole 24b and the connecting fixing hole 3b is inserted. By doing so, the base pile 21 and the support column member 3 are integrated. As a result, the base pile 21 and the support member 3 (collectively referred to as "support") are erected in the underground G1. When a plurality of columns are erected, the distance between the columns does not matter, but it is desirable to erection with an interval of about 2 meters.

As described in the one-piece type strut structure 1, a fence portion is attached to the strut member 3 by using a hook bolt or the like.

Then, the end cap 18 (17) is attached to the upper end of the support column member 3. Through the above steps, the two-piece type strut structure 2 is installed in the ground.

The fence installed in the one-piece type strut structure 1 and the fence installed in the two-piece type strut structure 2 may be installed next to each other. In such a case, the fences may be connected and fixed to each other. is there.

In this case, although not shown, a main body having a fixing hole in the center and hooks on both sides, and a pressing member having a fixing hole in the center and pressing the vertical rail 41 from the back surface side of the main body. Fences can be articulated and fixed using articulated fixtures such as bolts and nuts.

Specifically, the vertical rail 41 of one fence portion is hooked on the hook on one side of the main body, and the vertical rail 41 of the other fence portion is hooked on the hook on the other side of the main body. Next, the pressing member is pressed from the back surface side of the main body, and the vertical rail 41 is sandwiched by the pressing member and the hook. Then, by inserting bolts into the fixing holes of the main body and the pressing member and tightening the nuts, the fence portions can be connected and fixed to each other.
