Description

  The present invention relates to a columnar body building apparatus for building a columnar body in a vertical state and a columnar body building method using the columnar body building apparatus.

  In general, columnar bodies such as street lamps and utility poles are erected so that at least the bases thereof are vertical. For example, they are erected through the following construction work.

  First, as shown in FIG. 9, a vertical hole 61 having a predetermined depth (for example, about 1 m) is dug in the ground. Next, the columnar body 62 is lowered to the center in the vertical hole 61 by a plurality of workers. Next, a plurality of bar-like stays 63 are attached to the columnar body 62 while the operator holds the columnar body 62. Thereafter, while the worker holds the columnar body 62, another worker adjusts the attachment angle of the stay 63 and temporarily fixes the columnar body 62 in a vertical state. Then, concrete is placed into the vertical hole 61. As soon as the concrete is cured, the stay 63 is removed, and the vertical installation work of the columnar body 62 is completed.

  However, when the columnar body 62 is installed in a vertical state using this method, it is necessary to remove the stay 63 after the concrete is hardened, which may increase work time and cost. Further, when the stay 63 is removed, it is not possible to perform a paving work or the like around the columnar body 62, and the work efficiency may be reduced.

On the other hand, as shown in FIG. 10, after inserting a plurality of supports 73 between the inner peripheral surface of the vertical vertical hole 71 and the outer peripheral surface of the columnar body 72, and temporarily fixing the columnar body 72 in a vertical state, A technique has been proposed in which the columnar body 72 is erected in a vertical state by placing concrete in the vertical hole 71 with the support 73 attached (see, for example, Patent Document 1). More specifically, the support member 73 protrudes from a contact portion 74 having a concave cross section that contacts the outer peripheral surface of the columnar body 72, and from the back surface of the contact portion 74, and has a screw portion 75 at the tip. Part 76. Then, after bringing both abutting portions 74 into contact with the columnar body 72, the screw portion 75 is rotated, and the tip of the screw portion 75 is brought into contact with the inner peripheral surface of the vertical hole 71. In this manner, by inserting a plurality of support tools 73 between the vertical holes 71 and the columnar bodies 72, the columnar bodies 72 are supported by the plurality of support tools 73 and temporarily fixed in a vertical state. Next, by placing concrete in the vertical hole 71 while the columnar body 71 is supported by the support tool 73, the columnar body 72 is built in a vertical state. By adopting the technique, the support tool 73 is buried in the concrete, so that the work of removing the support tool 73 after the concrete is hardened is unnecessary. In addition, it is possible to perform paving work around the columnar body 72 immediately after placing the concrete.
JP-A-11-323962

  However, when performing the installation work of the columnar body 72 using the above-described conventional technique, when the support tool 73 is fitted between the vertical hole 71 and the columnar body 72, the operator supports the support tool 73 by hand in the vertical hole 71. However, it is necessary to rotate the screw portion 75. Further, since the two or more support members 73 are positioned in the circumferential direction of the outer peripheral surface of the columnar body 72 with the columnar body 72 interposed therebetween, and are stretched in the vertical hole 71, the screw portion of each support member 73 It is difficult to adjust the degree of tension by 75 rotations. If one support tool 73 is pulled strongly, the rotation allowance of the screw part 75 of the other support tool 73 is taken away. Conversely, if it is weak, the support tool 73 falls off. In addition, it is extremely difficult to firmly fix the columnar body 72 while adjusting the verticality according to the degree of tension of the support members 73. For this reason, workability | operativity is bad and there exists a possibility that the support tool 73 may fall in the vertical hole 71, and the installation operation | work which a very troublesome by several workers will be needed. As a result, there is a concern that work time and human costs will increase.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to build a columnar body that can relatively easily build a columnar body in a vertical state and can reduce work time and cost. It is providing the columnar body installation method using the attaching apparatus and the said columnar body installation apparatus.

  In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

Means 1. A columnar body building apparatus for building a columnar body in a vertical state,
A cylindrical body inserted into a vertical hole dug in the ground;
A pair of sandwiching members that can sandwich and hold the columnar body inserted into the cylindrical body, and project in opposite directions from the sandwiching member, and are stretched against the inner peripheral surface of the cylindrical body to thereby squeeze the columnar body. A columnar body building apparatus comprising: a support unit including at least a pair of extendable support members to support.

  The term “cylindrical body” is intended to include not only a cylindrical shape in a strict sense but also a bottomed one (hereinafter the same). Moreover, after inserting the cylindrical body into the vertical hole dug in the ground, for example, the periphery of the cylindrical body may be backfilled with the remaining soil, or the cylindrical body may be interposed via a spacer between the vertical hole and the cylindrical body. May be temporarily fixed, and the cylindrical body and the vertical hole may be integrated with concrete or the like to be placed later.

  According to the means 1, the columnar body is held in the cylindrical body by holding the columnar body with the clamping member and then stretching the extendable support member protruding from the clamping member against the inner peripheral surface of the cylindrical body. Will be temporarily fixed.

  Here, the supporting unit is attached to the columnar body by the clamping member sandwiching the columnar body. Therefore, the support member can be adjusted in a state where the support unit is fixed by the holding member. Moreover, since there is no possibility that the support unit falls into the cylindrical body, after the columnar body is inserted into the cylindrical body, the columnar body can be temporarily fixed by only one operator. Accordingly, it is possible to temporarily fix the columnar body relatively easily without much effort and labor, and it is possible to reduce work time and cost.

  In addition, for example, it is possible to attach the support unit to the columnar body before the columnar body is inserted into the cylindrical body. For this reason, the support unit can be attached relatively easily as compared with the case where the support unit is attached after the columnar body is inserted into the cylindrical body.

  Furthermore, the support member is configured to be extendable and contractible, and the tilt of the columnar body can be adjusted by appropriately extending and contracting the support member. Thereby, the columnar body can be more accurately installed in the vertical state. Moreover, it can respond to the multiple types of cylindrical body which has various internal diameters by making a support member extendable. As a result, the cost can be further suppressed.

  In addition, the columnar body is temporarily fixed by the support member stretching against the inner peripheral surface of the cylindrical body. For this reason, the columnar body can be temporarily fixed more stably as compared with the case where the support member directly stretches against the inner peripheral surface of the vertical hole dug in the ground.

  In addition, concrete or the like can be placed in the cylindrical body while the columnar body is supported by the support unit in the cylindrical body. As a result, work such as removal of the support unit after placing concrete becomes unnecessary, and work time and cost can be further suppressed. Moreover, it becomes possible to perform pavement work around the columnar body immediately after placing the concrete, and work efficiency can be improved.

  In addition, since the support unit is fixed to the columnar body by a clamping member, the support unit functions as a so-called “root” after the concrete is placed. For this reason, the support strength of the columnar body is increased, and as a result, the standing state of the columnar body can be made more stable.

Mean 2. The support unit is

  According to the means 2, the columnar body can be clamped by the clamping member by rotating the first nut. Further, by rotating the second nut, the tubular portion can be relatively moved along the longitudinal direction of the rod-like member, and as a result, can be stretched against the tubular body. That is, the rod-shaped member, the second nut, and the cylindrical portion constitute a support member that can be expanded and contracted in the means 1. Therefore, basically the same function and effect as the above-described means 1 are achieved.

  In addition, a support unit that is buried in concrete and cannot be reused needs to be prepared for each installation of the columnar body, and it is desirable to suppress the cost required for the support unit as much as possible. In this regard, according to the present means 2, the support unit can be realized with a relatively simple configuration. As a result, the increase in cost can be further suppressed.

  Further, by rotating the first nut, the clamping member can be relatively moved along the longitudinal direction of the rod-shaped member. As a result, the vertical adjustment of the columnar body can be performed also by the rotation of the first nut.

  When the vertical adjustment of the columnar body is performed by adjusting the first nut, the second nut is rotated to bring the cylindrical portion into contact with the cylindrical body, so that the support unit is moved to the cylindrical body. It is desirable to support with. On the other hand, when adjusting the columnar body by adjusting the second nut, the support unit is attached to the columnar body by rotating the first nut and clamping the columnar body with the clamping member. It is desirable to install it in a self-holding state.

Means 3. The support unit is

  Means 5. The columnar body construction apparatus according to claim 4, wherein the plurality of support units are attached to the columnar body so that the axial directions of the rod-shaped members of the respective support units are substantially orthogonal to each other.

  According to the means 5, basically the same effects as the means 4 can be obtained. In addition, it is possible to adjust the inclination of the columnar body along the X-axis direction and the Y-axis direction, that is, vertically adjust the columnar body in two directions at right angles by the plurality of support units. For this reason, the vertical adjustment of the columnar body can be performed more easily and more accurately.

  Means 6. 6. The columnar body building apparatus according to any one of means 1 to 5, wherein the clamping member is capable of surface contact with the columnar body.

  According to the means 6, the clamping member is configured to be able to come into surface contact with the columnar body. Therefore, the contact area between the clamping member and the columnar body can be made relatively large, and the columnar body can be clamped more firmly. As a result, the columnar body can be temporarily fixed in a more stable state.

  Means 7. 7. The columnar body building apparatus according to any one of means 1 to 6, wherein the front end portion of the support member can come into surface contact with an inner peripheral surface of the cylindrical body.

  According to the said means 7, the front-end | tip part of a supporting member is comprised so that a surface contact is possible with respect to the internal peripheral surface of a cylindrical body. Therefore, the support unit is supported more stably with respect to the cylindrical body, and as a result, the columnar body can be temporarily fixed in a more stable state.

  The “filler” refers to a concrete or the like that can be fixed in a standing state by being filled and cured in a cylindrical body.

  By using the columnar body building method of the means 8, the columnar body can be built in a vertical state relatively easily, and the working time and cost can be reduced.

  Hereinafter, an embodiment will be described with reference to the drawings.

  As shown in FIGS. 1 to 3, the columnar body building apparatus 1 includes a void sleeve 4 as a cylindrical body that is inserted into a vertical hole 3 dug in a planned standing position of a columnar pole 2 as a columnar body. And two sets of upper and lower support units 5a and 5b.

  The void sleeve 4 has a cylindrical shape, and is formed of, for example, cardboard having a predetermined thickness. The void sleeve 4 in the present embodiment has a predetermined inner diameter (for example, 400 mm) and a predetermined height (for example, 1 m20 cm).

  Each of the support units 5 a and 5 b includes a pair of clamping members 6 and a pair of rod-like members 7.

  The clamping member 6 is made of a channel (groove-shaped) steel material, and includes a bottom wall portion 8 and side wall portions 9 and 10 erected from both sides of the bottom wall portion 8. In addition, a pair of through holes 11 are formed through both ends of the bottom wall portion 8 (see FIG. 2).

  The rod-shaped member 7 is formed of a predetermined metal material (for example, steel), and a male thread portion is formed over the entire outer peripheral surface. Then, by inserting the rod-shaped member 7 through the through hole 11, the clamping member 6 and the rod-shaped member 7 are assembled in a square shape (lattice shape).

  Further, the bar-like member 7 is screwed with a nut 13 as a first nut that contacts the outside of the bottom wall portion 8, that is, the surface opposite to the side where the pole 2 is sandwiched. By rotating the nut 13, the distance between the both clamping members 6 can be adjusted, so that the pole 2 can be clamped.

  In addition, a contact member 14 is attached to each end of each rod-like member 7. The contact member 14 includes a cylindrical portion 15 having an inner diameter larger than the outer diameter of the rod-shaped member 7, a ring-shaped washer portion 16 fixed to the cylindrical portion 15 by welding or the like, and the washer portion 16. It consists of a nut portion 17 as a second nut that is fixed and screwed to the rod-shaped member 7, and the three members are integrally formed.

  For this reason, the contact member 14 can be moved along the longitudinal direction of the rod-shaped member 7 by rotating the contact member 14. That is, in this embodiment, the rod-shaped member 7 and the contact member 14 constitute a support member that can be expanded and contracted.

  Next, the vertical mounting method of the pole 2 using the columnar body mounting apparatus 1 described above will be described.

  First, as shown in FIG. 4, a vertical hole 3 having a predetermined depth (for example, 1 m20 cm) and a predetermined inner diameter (for example, 500 mm) is dug in the planned standing position of the pole 2.

  Next, the void sleeve 4 is inserted into the vertical hole 3. After inserting the void sleeve 4, the gap between the outer peripheral surface of the void sleeve 4 and the inner peripheral surface of the vertical hole 3 is filled with earth or sand.

  On the other hand, as shown in FIG. 5, the support units 5 a and 5 b are attached to the base end portion of the pole 2. More specifically, the nut 2 is tightened after the pole 2 is inserted between the pair of clamping members 6. As a result, the pole 2 is sandwiched between the both clamping members 6, and the support units 5 a and 5 b are fixed to the pole 2 in a self-held state. Thereby, support unit 5a, 5b will be in the state by which the movement to an up-down direction was controlled. In the present embodiment, the support units 5a and 5b are attached to the pole 2 so that the rod-like members 7 are orthogonal to each other after a predetermined interval.

  Next, a plurality of workers lower the base portion of the pole 2 to which the support units 5 a and 5 b are attached to the substantial center of the void sleeve 4.

  Next, the contact member 14 is rotated to temporarily fix the pole 2 to the void sleeve 4 while keeping the pole 2 in a vertical state.

  When the pole 2 is vertically adjusted, an installation confirmation jig 51 (see, for example, JP-A-2005-264555) as shown in FIG. 6 is preferably used. The installation confirmation jig 51 is suspended from the test plate 52, the first suspended portion 53, the second suspended portion 54, and the suspended portions 53, 54, and has a first weight 55 having a conical shape. And a second weight 56. The test plate 52 has a through hole in the center, and a first index line 57 and a second index line 58 that extend in directions orthogonal to each other are provided on the upper surface of the test plate 52.

  In the present embodiment, the test plate 52 is attached to the pole 2 in a horizontal state. In addition, the test plate 52 has the direction of the axis of the rod-shaped member 7 of the support unit 5a and the direction of the second index line 58 matched, and the direction of the axis of the rod-shaped member 7 of the support unit 5b It is attached so that the direction of one index line 57 coincides. In addition, a first hanging part 53 is attached vertically above the first index line 57, and a second hanging part 54 is attached vertically above the second index line 58. Thereby, when the pole 2 is erected in the vertical state, the tip portion of the first weight 55 is located immediately above the first index line 57 and the tip of the second weight 56 is placed. The portion is positioned immediately above the second index line 58.

  The vertical adjustment of the pole 2 using the installation confirmation jig 51 is performed by one operator as follows. First, the contact member 14 of the support unit 5b (5a) is stretched against the void sleep 4 to temporarily fix the pole 2. Next, the contact member 14 of the support unit 5a (5b) is rotated and adjusted, and the tip portion of the first weight 55 (second weight 56) is the first index line 57 (second index line 58). Adjust the inclination of the pole 2 so that it is directly above. Then, with the tip of the first weight 55 (second weight 56) being directly above the first index line 57 (second index line 58), the contact of the support unit 5a (5b) The contact member 14 is stretched against the void sleeve 4.

  Next, by rotating and adjusting the contact member 14 of the support unit 5b (5a), the tip portion of the second weight 56 (first weight 55) becomes the second index line 58 (first index line). 57) Adjust the inclination of the pole 2 so that it is directly above. The support unit 5b (5a) is brought into contact with the tip of the second weight 56 (first weight 55) being directly above the second index line 58 (first index line 57). The member 14 is stretched against the void sleeve 4. As a result, the pole 2 is temporarily fixed in a vertical state.

  That is, in the present embodiment, the support units 5a and 5b are combined so as to be orthogonal to each other, so that the inclination of the pole 2 can be adjusted in two vertical directions.

  After the pole 2 is temporarily fixed in a vertical state, concrete is placed in the void sleeve 4 with the support units 5a and 5b attached to the pole 2. With this, the vertical installation work of the pole 2 is completed.

  As described above in detail, in the columnar body building apparatus 1 according to the present embodiment, the abutting member 14 is adjusted in a state in which the support units 5a and 5b are fixed to the pole 2 by the clamping member 6. Can do. Further, since there is no possibility that the support units 5a and 5b fall into the void sleeve 4, after the pole 2 is inserted into the void sleeve 4, the temporary fixing operation of the pole 2 is performed by only one operator. Can do. Therefore, the pole 2 can be temporarily fixed relatively easily without much effort and labor, and as a result, working time and cost can be reduced.

  In addition, the support units 5 a and 5 b can be attached to the pole 2 before the pole 2 is inserted into the void sleeve 4. For this reason, the support units 5a and 5b can be attached relatively easily as compared with the case where the structure in which the support units 5a and 5b are attached after the pole 2 is inserted into the void sleeve 4 is adopted.

  Furthermore, the inclination of the pole 2 can be adjusted by operating the contact member 14. Thereby, the pole 2 can be more accurately installed in the vertical state. Moreover, since it can respond to the multiple types of void sleeve 4 which has various internal diameters, the further suppression of cost can be aimed at.

  In addition, the support units 5a and 5b are combined so as to be orthogonal to each other, so that the inclination of the pole 2 can be adjusted in two vertical directions. For this reason, the vertical adjustment of the pole 2 can be performed more easily and more accurately.

  In addition, the pole 2 is temporarily fixed by the abutting member 14 stretching against the inner peripheral surface of the void sleeve 4. For this reason, the pole 2 can be temporarily fixed more stably as compared with the case where the contact member 14 directly stretches against the inner peripheral surface of the vertical hole 3 dug in the ground.

  In addition, concrete or the like can be placed in the void sleeve 4 while the pole 2 is supported by the support units 5 a and 5 b in the void sleeve 4. As a result, work such as removal of the support units 5a and 5b after placing the concrete becomes unnecessary, and work time and cost can be further reduced. In addition, it is possible to perform paving work around the pole 2 immediately after placing the concrete, and work efficiency can be improved.

  Furthermore, since the support units 5a and 5b are fixed to the pole 2 by the clamping member 6, the support units 5a and 5b function as a so-called “root” after the concrete is placed. For this reason, the support strength of the pole 2 is increased, and as a result, the standing state of the pole 2 can be made more stable.

  In addition, since each of the support units 5a and 5b is supported at four points, the support units 5a and 5b can be stably supported with respect to the void sleeve 4, and as a result, the pole 2 can be supported with respect to the void sleeve 4. And stable support.

  In addition, the support units 5a and 5b have a relatively simple configuration, and can further suppress an increase in cost.

  At the same time, the rod-shaped member 7 connects both the clamping members 6 and supports them to the void sleeve 4. For this reason, compared with the case where a connection member and a support member are provided separately, the reduction of a number of parts can be aimed at.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, each of the support units 5a and 5b is provided with four contact members 14, and as a result, two pairs of support members are formed. Is not limited to two pairs. For example, as shown in FIG. 7, a pair of connecting members 22 are inserted into the through holes of the holding members 6, and nuts 23 are screwed to both ends of each connecting member 22 to connect the both holding members 6. Thus, a pair of support members 21 that are separate from the connection member 22 may be provided. Three or more pairs of support members may be provided.

  (B) In the above embodiment, the vertical adjustment of the pole 2 is performed by adjusting the contact member 14. However, the vertical adjustment of the pole 2 may be performed by adjusting the nut 13. That is, after the pole 2 to which the support units 5a and 5b are attached is inserted into the void sleeve 4, the contact members 14 of the support units 5a and 5b are stretched on the void sleeve 4 and then both the support units 5a and 5b are supported. It is good also as adjusting the pole 2 vertically by adjusting the nut 13 and moving the clamping member 6 relative to the longitudinal direction of the rod-like member 7.

  (C) In the above embodiment, the tip portion of the cylindrical portion 15 is a flat surface, but the tip portion of the abutting member 14 can be brought into surface contact with the inner peripheral surface of the void sleeve 4. It is good to do. In this case, for example, a curved surface portion that can be brought into surface contact with the inner peripheral surface of the void sleeve 4 may be provided at the distal end portion of the contact member 14. By providing such a curved surface portion, the contact area between the contact member 14 and the inner peripheral surface of the void sleeve 4 is further increased, so that the pole 2 can be temporarily fixed more reliably. In addition, as shown in FIG. 8, when the curved surface portion is provided, the curved surface portion 25 may be provided so as to connect the tip portions of the adjacent contact members 14. By providing the curved surface portion 25 in this manner, the pole 2 can be temporarily fixed more reliably. In addition, when providing the curved surface part 25 so that the front-end | tip parts of the adjacent contact member 14 may be tied in this way, it is necessary to provide the nut 17 of the contact member 14 separately.

  (D) In the above embodiment, the sandwiching member 6 has a rod shape, but the sandwiching member 6 may have a curved portion that can come into surface contact with the columnar pole 2. Thereby, the contact area of the clamping member 6 and the pole 2 can be made comparatively large, and the pole 2 can be clamped more firmly. As a result, the pole 2 can be temporarily fixed in a more stable state.

  (E) Although two sets of support units 5a and 5b are provided in the above embodiment, it is sufficient that at least one set of support units is provided. Therefore, three or more sets of support units may be provided. By providing a plurality of support units, the pole 2 can be supported more stably.

  (F) In the above embodiment, the support units 5a and 5b are attached before the pole 2 is inserted into the void sleeve 4, but the support units 5a and 5b are attached after the pole 2 is inserted into the void sleeve 4. It is good as well.

  (G) In the said embodiment, although the three parts of the cylindrical part 15, the washer part 16, and the nut part 17 are integrally formed, each may be formed separately. Further, an internal thread portion that can be screwed to the rod-shaped member 7 is formed in the tubular portion 15, and only the tubular portion 15 is connected to both end portions of the rod-shaped member 7 without providing the washer portion 16 and the nut portion 17. It is good also as comprising the supporting member 14 only by the said cylindrical part 15 by screwing together.

  (H) In the above-described embodiment, the installation confirmation jig 51 is used to stand the pole 2 vertically. However, other vertical adjustment tools may be used.

  (I) In the said embodiment, although the cylindrical part 15 has comprised the bottomless shape, a bottomed shape may be sufficient.

  (J) In the above embodiment, the cylindrical portion 15 has a cylindrical shape. However, for example, the cylindrical portion 15 may have a rectangular cylindrical shape or the like (such as a hexagonal cylindrical shape).

  (K) In the above embodiment, the void sleeve 4 has a cylindrical shape, but may have a polygonal cylindrical shape, for example.
