Description

  The present invention relates to a drive-in type strut device having a branch-like member and a column-standing construction method having a branch-like member. More specifically, the present invention relates to a drive-in support device having a branch-like member suitable for constructing a protective fence for preventing wild animals such as sharks and deer from entering farmland. The present invention relates to a method for erecting a support column having a branch member, which can easily stabilize the drive state of the support column and adjust the height of the branch member even when the drive state is later relaxed.

  In recent years, damage to crops caused by wild animals has been observed in various places, but damage caused by drought has been increasing.

  As an example of measures against damage caused by drought, for example, as shown in Patent Document 1, it is common to surround a farmland where crops are cultivated with a protective fence using a wire mesh, a resin net, a tin plate, a resin corrugated plate, etc. It was done.

  For example, the thing of a nonpatent literature 1 is proposed as a guard fence using a grid | lattice-like metal-mesh. As shown in FIG. 44, the guard fence a had an upper inclined portion c that was bent obliquely toward the outside of the farmland b. When constructing the guard fence a, the length portion d1 (FIG. 44 (B)) of about 30 cm above the wire mesh d having a height of about 1 m is angled 20-30 degrees outward from the vertical line. The wire mesh e provided with the upper inclined portion c is formed by bending the wire mesh e, and the wire mesh e having the upper inclined portion c is stretched on the support column formed by driving the support columns f into the ground at intervals of 1 to 2 m. And fixed to the support column f with a wire or the like.

  This guard fence a was developed with a focus on the behavior style of the kite where the kite jumps on the spot without jumping and jumps over the fence. As a result of having such a behavior pattern, when the heel tries to jump over the fence in the state of being close to the protective fence a, the upper inclined portion c of the fence is covered with the heel. It will be shifted backward. When the railroad crossing position is shifted rearward in this way, when the guard fence a is looked up from the viewpoint of the saddle, the height of the guard fence a looks higher than that of the guard fence in which the upper inclined portion c is not formed. . In addition, the distance between the fence and the protective fence is also increased. For this reason, the kite could be expected to give up the action of jumping over the fence itself, thereby avoiding the kite from entering the farmland. Such a protective fence a having the upper inclined portion c can actually prevent the leap from entering the fence and is an effective protective fence.

  However, since it took a lot of work to bend the upper part of the wire mesh at a required angle to form the special wire mesh e with the upper inclined portion c, there was a problem that the construction cost of the protective fence a was increased.

  Therefore, the present inventor prepares a bending column k in which the upper portion is bent obliquely upward and provided with an inclined piece j as shown in FIG. 45, and the bending column k is provided with a required interval (for example, about 1.5 m). At the interval), the lower column m is pushed into the ground n to be in an upright state, and then a protective fence r formed by stretching a commercially available fiber net q that is freely bent to the juxtaposed column row p. developed. Since the protective fence r is bent obliquely toward the outside of the farmland to form an inclined bent portion s, it has the same effect of preventing the intrusion of the fence from the protective fence a having the upper inclined portion c. I was able to demonstrate it.

  However, since the bent column k with the bent upper portion cannot be struck and driven into the ground n, the lower column m is pushed into the ground n. At this time, a pilot hole is provided in the ground in advance. It was necessary to insert the lower end of the column into the lower hole and then push the column into the ground by holding the side of the column with both hands. For this reason, there has been a problem that it is difficult to perform the work of pushing the bending column into the ground, which requires labor. In addition, when the ground surface is uneven, the length of the inclined piece j is likely to be uneven because the length of the column to be pushed differs depending on the place. Therefore, a very troublesome adjustment operation is required in which the column is further pushed in or the column is slightly pulled out so that the height of the inclined piece j must be made uniform. As described above, the protective fence constructed using the bent column k having the inclined piece j has a problem in that the construction efficiency is poor and the construction cost is increased.

  In addition, the bent column k whose upper part is bent must be a column dedicated to the construction of a protective fence, and a commercially available column generally used for plant cultivation or the like cannot be substituted, resulting in poor economic efficiency. There was also a problem.

  In addition, when a portion of the column inserted into the ground is loosened after a certain period of time, if the bent column k is further pushed into the ground, the inclined piece j is lowered, and the upper end height of the protective fence is increased. Therefore, there is a problem that the desired anti-bacterial effect is not exhibited.

  The present invention has been developed in view of, for example, the above-described conventional problems, and includes a driving-type support whose upper end is a striking portion, and a branch-like member protruding from a side shaft portion of the support by retrofitting. By adopting the basic configuration, it is possible to easily and surely set up the pillar with respect to the ground, and when there is unevenness in the ground or there are variations in the striking length of the pillar, It is an object of the present invention to provide a driving type strut device having a branch-like member that can easily align the height of the like-like member.

  It is a further object of the present invention to provide a driving-type strut device having a branch member that can easily set the protruding direction of the branch member in the horizontal plane.

  It is another object of the present invention to provide a driving-type strut device having a branch-like member that can securely fix the branch-like member to a strut having a slightly different diameter.

  Also, providing a column-standing construction method with a branch member that can easily stabilize the column striking state and adjust the height of the branch member even when the strut is loosened later. Is an issue.

In order to solve the above problems, the present invention employs the following means.
That is, the driving-type support device (hereinafter referred to as a support device) having a branch-shaped member according to the present invention includes a driving-type support column whose upper end is a striking portion and a branch-shaped member projecting from the support column. A support device comprising a member, wherein the branch member is fixed to the side shaft portion at a base end of a branch-like protruding piece that protrudes from a side shaft portion that forms a top end portion of the side surface portion of the support column. A fixing portion is provided, and the fixing portion has a fitting cylinder portion including a pair of left and right gripping pieces that form a fitting groove for fitting the side shaft portion, and the fitting cylinder portion is provided in the fitting groove. With the side shaft portion fitted, the side shaft portion can slide in the length direction and can rotate in the circumferential direction of the side shaft portion. In addition, screw shaft pieces project from the ends of both holding pieces in a state of being opposed to each other with a required interval, and the side shaft portion is inserted into the fitting groove while elastically expanding the screw shaft pieces. In addition, a male screw portion is provided on the outer peripheral surface of the screw shaft piece, and the screw shaft formed by the left and right screw shaft pieces can be screwed with the female screw portion of the operation nut member. As the operation nut member is tightened, the left and right gripping pieces tighten the side shaft portion, whereby the fixing portion is fixed to the side shaft portion. .

  In the strut device, a restricting projection is provided on the inner surface of the two screw shaft pieces facing each other along a longitudinal center line thereof, and when the two screw shaft pieces are in a free state, a gap is provided between the two restricting protrusions. The regulating protrusion has a linear guide surface extending in the length direction in parallel with the inner surface in a state of being lifted from the inner surface of the screw shaft piece, and the linear guide surface. An inclined guide surface inclined outward toward the tip of the screw shaft piece at the tip of the screw shaft piece, and formed at the tip of the inclined guide surface on the inside of the tip of the screw shaft piece. It is preferable that the inclined surfaces that are inclined outwardly are connected in series, and thereby, a guide recess is formed at the tip of the screw shaft.

  It is preferable that the side shaft portion is configured by fitting an adjustment ring member for adjusting the diameter of the support column to the side surface portion.

  When the adjustment ring member is provided, the adjustment ring member may be a C-shaped adjustment ring member. The C-shaped adjusting ring member has a C-shaped piece having a split groove-shaped opening and a circular outer peripheral surface, and the C-shaped piece elastically opens the opening. The C-shaped piece can be slid in the length direction of the support column while being elastically fitted to the side surface portion while being expanded, and above and below the C-shaped piece, It is good to comprise as the flange provided which can contact | abut to the upper and lower ends of the said insertion cylinder part.

  In each of the strut devices, the base end portion of the branch-like projecting piece is connected to a support portion provided in the fixed portion so that the branch-like projecting portion can be pivoted up and down, and the branch-like projecting piece is required. It is good to comprise so that it may be fixed at an angle.

  In each strut device, the upper end portion of the strut protrudes above the fixing portion in a state in which the fixing portion is fixed to the side shaft portion, and the protruding portion has a driving state of the strut. It is preferable that when the support is loosened later, the support is used as a driving allowance when the support is further driven into the ground, and the fixing portion can be slid upward along the driving allowance.

  A column erecting method comprising a branch member according to the present invention is a column erecting method using a column apparatus having a driving allowance portion, wherein the column is struck by the striking portion and the required length is set on the ground. After driving, the fixing portion of the branch member is fixed at the required height position of the support column, and in the fixed state, the upper end portion of the support column is used as a driving margin portion protruding above the fixing unit, When the driving state is later relaxed, the striking part is struck to drive the strut to the ground for the required length, and then the fixing part is released from the fixed state, and the fixing part is moved along the driving margin part. It is slid in the direction, the height of the branch member is returned to the initial state, and the fixing portion is fixed to the side shaft portion.

The present invention has the following excellent effects.
(1) A strut device according to the present invention includes a driving-type strut whose upper end is a striking portion, and a branch-like member protruding from the strut by retrofitting, and the branch-like member extends in the length direction of the strut. It can slide and is fixed to the column at the required height.

  Therefore, according to the present invention, when the column is erected on the ground, for example, unlike the case where a bent column as shown in FIG. 45 is erected on the ground, a lower hole is provided in the ground and the lower end of the column is inserted into the lower hole. By striking the upper end of the column with the branch member removed, the column can be easily and reliably erected with respect to the ground. In addition, the branch member can slide in the length direction of the column and is fixed to the column at the required height position. Therefore, even if there is unevenness in the ground or the driving length of the column varies, the branch member It is easy to make the height of the same. Therefore, unlike the case where the column having the inclined piece portion provided integrally is erected on the ground, it is not necessary to use a nerve to adjust the piercing length of the column in consideration of the unevenness of the ground. Or, there is no need for construction work for height adjustment such as raising the required length of the strut once pushed in.

  For this reason, a net or sheet can be attached to the upright column with protruding branch members to build a protective fence that prevents wild animals such as sharks and deer from entering the farmland. When constructing sunshades, rain shields, etc., the construction can be facilitated and the construction efficiency can be improved.

(2) Since the present invention adopts a configuration in which the fixing portion of the branch member is fixed to the side shaft portion of the support column, the upper end portion of the support column can be projected above the fixing portion. Unlike the case where the branch member is directly projected at the upper end of the arm, the striking portion of the column is exposed even when the branch member is fixed.

  Therefore, when the striking state of the support column with respect to the ground is loosened, it is possible to stabilize the standing state of the support column by striking the striking portion and further driving the support column, and to fix the fixing portion of the branch member. By sliding it up by the length of the drive-in and re-fixing it to the column, the height of the branch-like protrusions of the protective fence, etc. is aligned (including a state where the height is slightly different even if the height is slightly different) ) Can return to the original state.

(3) A strut device according to the present invention includes a driving-type strut whose upper end is a striking portion, and a branch-like member protruding from the post to be attached later, and a separate strut and a branch-like member. Therefore, the support column can be replaced with a commercially available support column that is generally used for plant cultivation and the like, and is excellent in economic efficiency.

(4) When an adjustment ring member is fitted to the side surface of the column to configure the side shaft, the column used is smaller than the inner diameter of the insertion tube portion even if it is smaller in diameter than the column. There is an advantage that the same branch member can be used. By configuring the adjustment ring member in a C shape, there is an advantage that the adjustment ring member can be easily fitted to the side surface portion from the lateral direction.

(5) When the fixing portion of the branch member is configured to be able to rotate in the circumferential direction of the column, the height of the branch member can be set as required, and the protruding direction of the branch member in the horizontal plane can also be set. There is an advantage that it can be easily adjusted, and the operation of adjusting the direction of the branch member after the support is driven into the ground can be made more efficient.

(6) When the fixing portion of the branch member is configured with an insertion tube portion composed of a pair of left and right holding pieces, the fixing portion can be fixed in a stable state to a plurality of types of struts having different diameters within a certain range. Become. And, by screwing the screw shaft piece at the tip of the both holding pieces, by screwing the female thread portion of the operation nut member to the screw shaft formed by the both screw shaft pieces, by tightening the operation nut member, The left and right gripping pieces can be in a state where the side shaft portion is fastened, whereby the branch member can be easily fixed to the support column.

(7) In particular, in the case where a regulating protrusion formed by connecting an inclined guide surface to the end of a linear guide surface is provided on the inner surfaces of the two screw shaft pieces facing each other, the side shaft portion is provided with the inclined guide surface, The guide can be smoothly inserted into the insertion groove of the fixed portion while being guided by the linear guide surface.

(8) When the branch-like projecting portion can be rotated in the vertical direction with respect to the fixed portion and is configured to be fixed at a required angle, the projecting direction of the branch-like projecting portion is not only obliquely upward, It is easy to set in the horizontal direction or obliquely downward, and not only a protective fence but also an awning, a rain shield and the like can be configured, so that it is possible to achieve an expanded use of the column device according to the present invention.

(9) When using the column erecting method comprising the branch member according to the present invention, stabilization of the column driving state and adjusting the height of the branch member even when the column driving state is later loosened. It can be done easily.

In other words, the outer peripheral edge portion 58 is fitted into the guide recess 57, whereby the screw shaft pieces 35 and 35 are firmly squeezed. As a result, the C-shaped adjustment ring member 62 a is fixed to the support column 3, the fitting tube portion 32 is fixed to the C-shaped adjustment ring member 62 a, and the fitting tube portion 32 is fixed to the support column 3. The That is, the fixing portion 20 is fixed to the support column 2 at a required height position of the support column 2.

  FIG. 17 shows a part of a protective fence 71 that is constructed by using the strut device 1 having such a configuration and prevents the straw from entering the farmland. When constructing the protective fence 71, for example, as shown in FIG. 18, the support columns 3 are driven into the ground 59 along the periphery 73 of the farmland 72 at intervals of, for example, 1.5 m. At that time, the striking portion 2 at the upper end of the support column is hit, and a length portion of, for example, about 30 cm of the lower support portion 60 is driven into the ground. After the strut 3 is driven, the fixing portion 20 of the branch member 5 is attached at the approximate height position of the side shaft portion 29. The operation nut member 55 is loosely attached. In this way, the branch members 5 are fixed to the respective pillars 3 while the plurality of pillars 3 are erected in the vertical state. When the fixing portion 20 is attached to the side surface shaft portion 29, the side surface shaft portion 29 is inserted into the insertion groove 30. As described with reference to FIG. In addition to being the side surface portion 16 of the support column 3, as described above with reference to FIG. 10, the side surface shaft portion 29 is configured by fitting the C-shaped adjustment ring member 62 a to the side surface portion 16. Sometimes. The side shaft portion 29 is set in the insertion groove 30.

  When the column 3 is erected in this way, in the corner 76 of the farmland 72, for example, as shown in FIG. 19, the branch-like member 5 is opposed to the column columns 77a and 77b sandwiching the corner 76 in plan view. For example, the fixing portion 20 is attached to the support column 3 by adjusting the protruding direction of the branch-shaped protruding piece 17 so as to protrude in a 45-degree direction. The direction adjustment can be performed by appropriately rotating the fitting tube portion 32 in the circumferential direction of the side shaft portion 29. 20 to 21 show a state in which the branch members 5 and 5 are fixed to the support column 3 located at the corner 76 of the farmland 72 in two upper and lower stages. For example, the branch-like projecting piece 17a of the upper branch-like member 5a projects in the same direction as the branch-like projecting piece 17A of the branch-like member 5 of one column row 77a sandwiching the corner 76, and is located below. The branch-like projecting piece 17 b of the branch-like member 5 b is projected in the same direction as the branch-like projecting piece 17 B of the branch-like member 5 of the other column row 77 b constituting the corner 76.

  After that, as shown in FIG. 17, a fiber protective net 79 made of polyethylene or the like is stretched on the support column 77 outside the farmland 72. At this time, as shown in FIG. The upper end edge 80 of 79 is hooked on the upper hooking piece 26 of the branch-like projecting piece 17, and the lower side portion 81 of the upper end edge 80 of the protective net 79 is placed on the lower side of the branch-like projecting piece 17. It hooks on the hooking piece 27, and the lower net portion 82 is hung along the support column 3 as shown in FIGS. As a result, the protective net 79 is naturally bent along the outer surface of the column 77.

  In this way, the protective net 79 is attached to the branch-like projecting piece 17 of each support column. At that time, the height of each branch-like member 5 is set as required, and the operation nut member 55 is tightened to The fixing unit 20 is fixed to the column 3. As a result, the branch-like projecting piece 17 of the branch-like member 5 protrudes obliquely upward from the side surface portion 16 of the pillar at an inclination angle of 45 degrees, and the branch-like member 5 is fixed to the pillar 3 in this state. . In this embodiment, in this state, the upper end portion 75 of the support column 3 protrudes from the fixing portion 20 by about 5 to 15 cm. Usually, the protruding length differs depending on each column because the ground is not flat, but is common in that the upper end portion 75 of the column protrudes above the fixing portion 20. After that, as shown in FIG. 17, the protective net 79 is fixed to the lower end portion, the intermediate portion, and the upper end portion of the column 3 using the packer 83. Note that the lower end portion 89 of the protection net 79 stretched on the support column 77 is placed on the ground 59 as shown in FIG. 17 and is fixed to the ground 59 with a presser pin 90 or the like.

  FIG. 23 shows a light-shielding sheet such as a black sheet so as to cover the outside of the protective net 79 so as to shield a width portion of about 50 cm below the support column 3 for the purpose of a blindfolding effect for covering the crops with respect to the straw. 92 is stretched, and the light shielding sheet 92 is fixed to the column 3 by the packer 83 together with the protective net 79.

  As described above, the upper end portion 75 of the support column 3 is protruded above the fixed portion 20 when the driving state of the support column 3 is loosened after a certain period of time, for example, FIG. This is for providing a driving margin for stabilizing the column 3 by slightly driving the column 3 into the ground as shown in FIG. When the driving state of the support column 3 is loosened in the initial state shown in FIG. 24 (A), as shown in FIG. 24 (B), the hitting portion 2 is hit and the support column 3 is somewhat lengthened (for example, Drive into H1, ground 59 for a length of about 5cm). When driven in this way, the branch member 5 integrated with the column 3 is lowered by the amount H1 corresponding to the column 3 being driven. Therefore, as shown in FIG. 24C, the operation nut member 55 is loosened and the fixing portion 20 is slid upward (the slide direction is indicated by an arrow in FIG. 24B). By tightening the nut member 55, the protective fence 71 can be maintained in a stable state at the initial height. Then, by sliding the branch-like member 5 upward in this way, the height of the protective net 79 is also raised.

  When the guard fence 71 constructed in this way is used, each branch-like projecting piece 17 in the parallel state is bent obliquely upward, so that the branch net-like projecting piece 17 of the protection net 79 is in the parallel state. As shown in FIG. 25, the supported portion forms an inclined net portion 93 that covers the upper portion outside the column of columns 77.

  The action of preventing the entry of straw into the farmland 72 by the protective fence 71 constructed in this way is as follows. That is, as a result of the behavior that the kite jumps on the spot without jumping and jumps over the fence, when the kite jumps over the fence in the vicinity of the protective fence 71, the kite is placed outside the column 77. Since the inclined net portion 93 is formed so as to cover the upper portion, the inclined net portion 93 is covered with the bag. Therefore, the kite shifts the crossing position backward. When the guard fence 71 is looked up from the viewpoint of the saddle at the position where the railroad crossing position is shifted rearward in this way, the height of the guard fence looks higher than that of the guard fence 71 where the inclined net portion 93 is not formed. . In addition, the distance between the fence and the protective fence 71 is also increased. For this reason, it can be expected that the kite will give up the action itself that jumps over the protective fence 71, thereby preventing the kite from entering the farmland 72.
