  On the other hand, if the configuration of claim 5 is adopted, the beast intrusion protection fence according to the box shape of the above-mentioned field is similarly obtained by changing the direction of the horizontal rail around the axis of the vertical through bolt and fastening it to the pile. There is an effect that you can assemble.

  Hereinafter, the present invention will be described in detail with reference to the drawings. The beast intrusion protection fence of the present invention is basically a pile (A) and a cross rail (B) as shown in FIGS. The first and second end joints (EJ1) and (EJ2), which connect the horizontal beam (B) and the pile (A), as well as the vertical skewer (S) that intersects the horizontal beam (B) and the first It consists of two types of two intermediate joints (MJ1) and (MJ2), and anyone can use the necessary number of these components to perform assembly work conveniently on a Sunday carpentry.

  Speaking of the above components, first, the pile (A) is a steel pipe having a constant thickness (for example, about 48.6 mm) and thickness (for example, about 2 mm) and a height (for example, at least about 1500 mm). 5), the wedge-shaped pile tip (11) of a zinc die-cast product as shown in FIG. 5 is fitted and fixed to the lower end of the opening in the covering state, and the malleable cast iron is also fixed to the upper end of the opening. The stake protection cap (12) of the product is detachable so that it can be fitted and used in a covered state.

  If the upper end of the opening of the pile (A) is repeatedly subjected to the hammering force of the hammer (H) directly, there is a risk of deformation and damage, and the end joint (EJ1) (EJ2) from above to the pile (A) Since the intermediate joints (MJ1) (MJ2) and the head cap described later cannot be inserted securely and smoothly, they can be struck by the hammer (H) through the pile protection cap (12). It is.

  In this respect, in FIGS. 5 to 8, the pile protection cap (12) is crowned in an externally fitted state to the pile (A), and then the pile protection cap (12) is removed by screwing the butterfly bolt (13). It is designed to be pressed and fixed to the circumferential surface of the pile (A), but as suggested by the corresponding modification of FIG. 9, the installation of the butterfly bolt (13) is omitted, The pile protection cap (12) may be crowned so as to be fitted into the pile (A). In any case, the top surface of the pile protection cap (12) is a flat surface (12a) and a hammer (H ) Can be struck correctly.

  (14) Zinc that is replaced with the removal of the pile protection cap (12) after the pile (A) has been driven into the ground (G), and is fitted into the upper end of the pile (A) in a covered state. It is a head cap of a die-cast product, and is pressed and fixed to the circumferential surface of the pile (A) as shown in FIG. 10 by the screwing operation of the screw (15). The top surface of the head cap (14) is raised as a conical surface (14a). The head cap (14) and the pile protection cap (12) have a thickness of about 3 mm as an example.

  Next, the cross beam (B) is made of equilateral mountain type steel having a certain length (for example, two types of difference between about 900 mm and about 1800 mm) and a thickness (for example, about 3 mm), and is extracted in FIG. As shown in the figure, a large number of vertical skewer receiving holes (17) are distributed on the horizontal plate side (16x) with a constant pitch (P) that cannot pass not only deer and ridges but also small ridges. On the other hand, a pair of bolt receiving holes (18) are also formed at least at both ends of the vertical plate side (16y). However, the vertical skewer receiving hole (17) of the horizontal plate side (16x) is dimensioned to a diameter (for example, about 14 to 15 mm) that can also be used as the bolt receiving hole (18).

  Further, the vertical skewer (S) has a constant thickness (for example, about 13 mm) slightly thinner than the diameter of the vertical skewer receiving hole (17) in the horizontal rail (B), and a constant slightly shorter than the pile (A). Is a reinforcing bar (shaped steel bar) having a height of, for example, about 1200 mm or more, and freely passes through the vertical skewer receiving hole (17) of the cross beam (B) from above and is driven into the ground (G). Will be standing. This prevents the beast from digging a hole in the ground (G) and passing through or entering the hole.

  Two types of the first and second end joints (EJ1) (EJ2) mentioned earlier are zinc die-cast products, and the pile (A) that will be located at the end of the beast intrusion protection fence and the horizontal beam ( As for what is used to connect the end part of B), both of the first and second end joints (EJ1) and (EJ2) are inserted into the pile (A) so as to be able to move up and down from above, and are fixedly fitted. A mounting cylinder (19) having a large diameter (eg, about 49 mm), height (eg, about 60 mm) and thickness (eg, about 3 mm) is provided, and the screw (20) is screwed to the circumferential surface of the pile (A). It is pressed down and fixed and maintained at a predetermined height position of the pile (A).

  However, of the above two types, the first end joint (EJ1) has the horizontal rail (B) to the pile (A) and the horizontal through bolt (21x) axis (XX) as shown in FIGS. Is connected to the mounting cylinder (19) so that it can be raised and lowered, and a vertical one arm plate piece (22y) is continuously extended in one direction from the circumferential surface of the mounting cylinder (19). A bolt receiving hole (23) capable of communicating with the bolt receiving hole (18) on the vertical plate side (16y) in B) is formed at the center of the vertical one arm plate piece (22y).

  As is apparent from FIGS. 2 and 3, the horizontal beam (B) and the pile (A) are formed by the horizontal through bolt (21x) inserted into the bolt receiving holes (18) and (23) and the fixing nut (24x). ) Are integrated with each other, so that the cross rail (B) of the beast intrusion protection fence can be adapted to the undulation of the ground (G).

  In the illustrated example, the bolt receiving hole (23) of the first end joint (EJ1) is opened as a long hole extending along the protruding direction of the vertical arm plate piece (22y). Opening is acceptable. (25) is a pair of upper and lower rope receiving holes which are similarly distributed to the base end of the one arm plate piece (22y) with a smaller diameter than the bolt receiving hole (23). A bundling cable (26) such as a wire can be inserted therethrough.

  Compared to such a first end joint (EJ1), the second end joint (EJ2) has a horizontal through-hole (B) to a pile (A) as shown in FIGS. ), The horizontal one arm plate piece (22x) is continuously stretched in one direction from the circumferential surface of the same mounting cylinder (29). The bolt receiving hole (23) which is extended and can communicate with the vertical skewer receiving hole (17) of the horizontal plate side (16x) in the horizontal beam (B) has a center of the horizontal one arm plate piece (22x). An opening is formed in the part.

  As is apparent from FIGS. 33 to 35, the vertical skewer receiving hole (17) of the horizontal beam (B) that can also be used as the bolt receiving hole and the bolt receiving hole (23) of the second end joint (EJ2) are inserted. The horizontal beam (B) and the pile (A) are fastened and integrated by the vertical through bolt (21y) and the fixing nut (24y). The pier (B) can be adapted to the surrounding flat shape of the field.

  The bolt receiving hole (23) of the second end joint (EJ2) is opened as a round hole in the illustrated example, but the opening is extended as a long hole along the extending direction of the horizontal one arm plate piece (22x). Is of course good. A plurality of wire receiving holes (25) having a smaller diameter than that of the projecting base end portion of the horizontal one arm plate piece (22x) or the periphery of the bolt receiving hole (23) are also distributed. They can be passed through the bundling cord (26).

  On the other hand, two types of first and second intermediate joints (MJ1) and (MJ2) are also zinc die-cast products. Both are provided with the same mounting cylinder (19) as the first and second end joints (EJ1) (EJ2), and are used for rigidly connecting the ends of the mounting cylinder (19). ) Is inserted into the pile (A) so as to be movable up and down from above, and is pressed against the circumferential surface of the pile (A) by screwing the screw (20). Fixed and maintained in height position.

  Then, from the circumferential surface of the mounting cylinder (19) forming the first intermediate joint (MJ1), as shown in FIGS. 17 to 19, the vertical arm plate pieces (22y) project continuously and integrally in two opposite directions. And a bolt receiving hole (23) capable of communicating with the bolt receiving hole (18) on the vertical plate side (16y) of the horizontal rail (B) is provided at the center of the vertical arm plate pieces (22y). Each is formed with an opening.

  That is, the first intermediate joint (MJ1) is the same as the first end joint (EJ1), as is apparent from FIGS. 2 and 4, with the bolt receiving holes (23) of the vertical arm plate pieces (22y). With the axis (XX) of the horizontal through bolt (21x) inserted into the bolt receiving hole (18) of the horizontal beam (B) as a pivot, the horizontal beam (B) can be raised and lowered to the pile (A). It is connected, and the state is fastened and integrated by the fixing nut (24x) of the through bolt (21x). Therefore, the horizontal rail (B) can be installed at an inclination angle corresponding to the undulation of the ground (G).

  Unlike such a first intermediate joint (MJ1), from the circumferential surface of the mounting cylinder (19) forming the second intermediate joint (MJ2), as shown in FIGS. ) Is continuously extended in two opposite directions. It is preferable that both the arm plate pieces (22x) protrude from the upper end portion of the mounting cylinder (19). In addition, a bolt receiving hole (23) capable of communicating with the vertical skewer receiving hole (17) of the horizontal plate side (16x) in the horizontal beam (B) is provided at the center of each horizontal arm plate piece (22x). It is also open.

  That is, the second intermediate joint (MJ2) is the same as the second end joint (EJ2), as is apparent from FIGS. 33, 36 and 37, the bolt receiving holes (23 of the horizontal arm plate pieces (22x)). ) And the axis (YY) of the vertical through bolt (21y) inserted into the vertical skewer receiving hole (17) of the horizontal beam (B), the horizontal beam (B) to the pile (A) It is connected so that the direction can be freely changed, and the state is fastened and integrated by the fixing nut (24y) of the through bolt (21y). Therefore, it is possible to install the horizontal rail (B) as a direction corresponding to the shape of the surrounding field of the field.

  In addition, the receiving holes (25) of the bundling ropes (26) are also distributed in the both arm plate pieces (22x) (22y) of the first and second intermediate joints (MJ1) (MJ2). Since the arrangement, the diameter, etc. are substantially the same as those of the first and second end joints (EJ1) and (EJ2), only the corresponding reference numerals to FIGS. 12 to 16 are entered in FIGS. Detailed description thereof will be omitted.

  Further, reference numeral (27) shown in FIGS. 24 and 25 is a brace that prevents the beast intrusion protection fence from falling, and is composed of a steel pipe shorter than the above pile (A), and is in an inclined state intersecting with the pile (A). Will be inserted into the ground (G). The lower end of the opening of the brace (27) may be embedded and fixed in the ground (G) by backfilling instead of the piercing.

  (J) is a bracing joint for pivotally connecting the pile (A) and the brace (27), and the mounting cap (28) is also brazed as a zinc die-cast product as shown in FIGS. 27) is fitted into the upper end of the opening in a covered state, and is pressed and fixed to the circumferential surface of the brace (27) by the screwing operation of the screw (29).

  And in the center part of the arm plate piece (30) projecting continuously and integrally from the top surface of the mounting cap (28), an opening is made in the vertical one arm plate piece (22y) of the first end joint (EJ1). A bolt receiving hole (31) capable of communicating with the bolt receiving hole (23) is preferably formed as an elongated hole, and a horizontal through bolt (32) inserted into both the bolt receiving holes (23) (31). The bracing (27) is fastened and integrated with the pile (A) by the fixing nut (33). In that case, the direction in which the vertical one arm plate piece (22y) of the first end joint (EJ1) connected to the bracing joint (J) crosses the cross rail (B) when viewed from above the pile (A). Needless to say.

  Therefore, the brace (27) can be connected to the pile (A) so as to be raised and lowered with the horizontal axis (XX) of the penetrating bolt (32) as a rotation fulcrum, and the brace (27) can be connected to the ground ( G) can be embedded and fixed in a moderately inclined state. In addition, (34) indicates a splicing stick inserted into the ground (G) to prevent the bracing (27) from rising, and (35) suggests a binding line of the splicing stick (34) to the bracing (27). Yes.

  The beast intrusion guard fence of the present invention can be transported conveniently and compactly and lightly to the field in the mountainous area, which is the construction site, as a disassembled state of the above components. As shown in the first construction example of FIGS. 1 to 4, first, a plurality of piles (A) are driven into the ground (G) at predetermined intervals and are suspended. As described above, when the hammer (H) is driven, the pile protection cap (12) is fitted and used on the upper end of the opening of the pile (A).

  And according to the undulation of the ground (G), the surrounding flat shape of the field, etc., the first and second end joints (EJ1) (EJ2) and the first and second intermediate joints (MJ1) (MJ2) Select the two types selectively or use them together. In this regard, in the first construction example of FIGS. 1 to 4, the first end joint (EJ1) and the first intermediate joint (MJ1) are used.

  That is, the pile protection cap (12) is removed from the pile (A) that has been driven into the ground (G), and the first end is moved to the pile (A) that is positioned at the end of the beast intrusion protection fence. While inserting multiple pieces of joints (EJ1) (two in the upper and lower stages in the example) and fitting them together, the first intermediate joint is connected to the pile (A) that is also interposed in the middle part of the intrusion protection fence. The same plurality of (MJ1) is inserted and fitted, and the head caps (14) are fitted and fixed to the upper ends of the openings of all the piles (A).

  Before and after the fixing of the head cap (14), the first end joint (EJ1) and the first intermediate joint (MJ1) are screwed into the pile (A) by screwing each screw (20). After fixing and maintaining the pressed-down state at a predetermined height position, a plurality of (two in the illustrated example) horizontal rails (B) are inserted between adjacent piles (A), and the horizontal beam ( B) one end portion and the first end joint (EJ1) are fastened by a through bolt (21x) and a fixing nut (24x), respectively, while the other end portion of the cross beam (B) and the first intermediate portion are also fastened. The joint (MJ1) is also fastened by the through bolt (21x) and the fixing nut (24x).

  In that case, the bolt receiving hole (23) that opens to the vertical one arm plate piece (22y) of the first end joint (EJ1) and the both arm plate pieces (22y) of the first intermediate joint (MJ1) also open. The axis of the horizontal through bolt (21x) inserted between the bolt receiving hole (23) and the bolt receiving hole (18) opened in the corresponding vertical plate side (16y) of the cross beam (B). Before the fastening nut (24x) is tightened by using (XX) as a rotation fulcrum, the horizontal rail (B) is raised and lowered, as shown in FIG. ) Can be fastened and fixed to the pile (A) as an inclination angle along the undulation.

  In such a state that the horizontal beam (B) is fastened to the pile (A), the horizontal beam (B) is arranged in parallel as at least two upper and lower stages, so that the horizontal beam (16x) is finally opened on the horizontal beam (B). A large number of vertical skewers (S) are driven into the ground (G) from above through a large number of distributed vertical skewer receiving holes (17) to form a group. In addition, since the vertical skewer (S) freely passes through the vertical skewer receiving hole (17) of the horizontal rail (B), even if there is a water channel (36) or a rock (37) on the ground (G), The vertical skewers (S) can be clustered without hindrance.

  In particular, in the intrusion protection fence for the eaves, as is clear from another second construction example in FIGS. 29 to 32 corresponding to FIG. To the side (16y), preferably using a horizontal through bolt (21x) and a fixing nut (24x) for the first end joint (EJ1) and the first intermediate joint (MJ1), It is effective to assemble a film-shaped shielding material (38) such as a plate-like or colored vinyl sheet as an intrusion protection fence that cannot be seen through by the ridges.

  When the film-like shielding material (38) is adopted, as shown by the chain line in FIG. 11, a large number of bolt receiving holes (18) are arranged at a constant interval on the vertical plate side (16y) of the horizontal beam (B). It is desirable to prevent an exfoliation of the film-shaped shielding material (38) by opening an additional opening and inserting a through bolt (21x) here and fastening a fixing nut (24x).

  Anyway, according to the 2nd construction example of FIGS. 29-32, as the double structure where many of the vertical skewers (S) which consist of a reinforcing bar, and the shielding material (38) which cannot see through the wild beast mutually exist. Moreover, the possibility that a hole for passage / intrusion is dug in the ground (G) can be effectively prevented. The shielding member (38) is not limited to the entire horizontal rail (B) as shown in the figure, and may be stretched only on the lower half portion thereof.

  FIGS. 33 to 37 show still another third construction example corresponding to FIG. 2, and this corresponds to the surrounding planar shape of Tabata, which is the construction site, and the second end joint (EJ2) and the second construction. Using the intermediate joint (MJ2), both ends of the crosspiece (B) are fastened and integrated with the pile (A) located at the end of the beast intrusion protection fence and the pile (A) that is also interposed in the intermediate part. Yes.

  Bolt receiving hole (23) that opens to the horizontal one arm plate piece (22x) of the second end joint (EJ2) and bolt that opens to the horizontal both arm plate pieces (22x) of the second intermediate joint (MJ2) The axis of the vertical through-bolt (21y) inserted between the receiving hole (23) and the vertical skewer receiving hole (17) opened to the corresponding horizontal plate side (16x) of the crosspiece (B) Using (YY) as a pivot point, the direction of the horizontal rail (B) can be changed before the fixing nut (24y) is tightened.

  However, the first and second end joints (EJ1) (EJ2) and the first and second intermediate joints (MJ1) (MJ2) are both inserted into the pile (A) so that they can be raised and lowered. Therefore, it is possible to change the direction with the vertical axis of the pile (A) itself as a pivot, and as a result, as suggested in the fourth construction example of FIGS. The first end joint (EJ1) or the second end joint (EJ2) of the first end joint (EJ1) or the pile (A) that will be located at the end of the fence, It is also possible to insert and fix only one type in a stacked state, and to fasten the horizontal beam (B) in a stepped state between adjacent ones.

  In any of the first to fourth construction examples, the first and second end joints (EJ1) (EJ2) and the first and second intermediate joints (MJ1) (MJ2) are adjacent to the pile (A). 42 and 43, a binding rope (26), such as a wire rope or wire, is used to tie up and bind together in a crossed state to obtain an intrusion protection fence that can withstand the strong rushing force of the kite. be able to.

  In the example shown in the figure, the horizontal bars (B) made of angle steel are all L-shaped in side view, and the first and second end joints (EJ1) (EJ2) and the first and second intermediate joints (MJ1) (MJ2). ), But it can also be arranged as an inverted L shape in a side view. Also, it is desirable that the vertical distance between adjacent horizontal rails (B) be set to a dimension that does not form a stairway on which the beast climbs with its forefoot.
