Description

  The present invention relates to a method for installing a suspension door for installing a suspension door on an existing fence.

  Substations, distribution stations, and power transmission stations are fenced for safety. Fences are usually troublesome to repair because the supporting pillars are usually buried in the ground with concrete. Therefore, in order to solve such a problem, a method for repairing a fence described in Patent Document 1 has been considered.

  In the method for repairing a fence described in Patent Document 1, first, the fence body provided between the existing columns is removed, leaving the existing columns. Next, a cylindrical new column having a screw hole formed on the outer peripheral surface is disposed so as to cover the outer periphery of the existing column, and the new column is fixed to the existing column with a bolt. Then, the new fence main body is fixed to the new support column. According to this repair method, it is not necessary to remove the existing struts and embed the struts again, so that the fence repair work can be easily performed. Moreover, since the aging existing support | pillar is covered with a new installation support | pillar, the aesthetics of a fence can be improved.

Japanese Patent Application Laid-Open No. 11-200667

  By the way, according to the method for repairing a fence described in Patent Document 1, since the new support column is arranged so as to cover the existing support column, the existing support column and the new support column constitute a single support column. . In this configuration, when installing a door between the columns instead of renovating the fence, the doors arranged between the columns and the columns are arranged on the same plane. However, it was difficult to install a hanging door.

  Therefore, an object of the present invention is to provide a suspension door installation method that can easily install a suspension door on an existing fence.

  In order to solve the above problem, one aspect of the present invention is a suspension door installation method for removing a fence between a first existing pillar and a second existing pillar and installing a suspension door. In the first step, the fence is removed. In the second step, a new column comprising a columnar column main body and a support portion extending in a direction intersecting the column main body from one end of the column main body is used, and the tip end side of the support portion is the upper end portion of each existing column. And the other end of the column main body is brought into contact with the installation surface to be installed on each of the first existing column and the second existing column. In the third step, the suspension rail is fixed to the support portion of each new pillar fixed to the first existing pillar and the second existing pillar. In the fourth step, the suspension door is suspended from the suspension rail.

  According to the above configuration, the supporting part is connected so as to intersect the plane formed by the first existing pillar and the second existing pillar, so that the suspension door supported by the supporting part via the suspension rail is It arrange | positions in parallel with the said plane in the position away from the plane. For this reason, it becomes possible to install a suspension door on the existing fence. Moreover, since it is not necessary to remove a 1st existing pillar and a 2nd existing pillar in the case of installation of a suspension door, installation of a suspension door is easy.

  In another aspect, between the first existing column and the second existing column, the third existing column that supports the fence together with the first existing column, and the second existing column or the third existing column can be rotated as an axis. A hinged door is provided. In this case, in the first step, the fence, the third existing pillar, and the hinged door are removed.

  The opening width of the hinged door is substantially equal to the interval between the second existing pillar and the third existing pillar. Since the fence, the third existing pillar, and the hinged door are removed, the opening width of the door is expanded to the interval between the first existing pillar and the second existing pillar. Moreover, since a hanging door is installed instead of the hinged door between the first existing pillar and the second existing pillar, the door is prevented from contacting an obstacle when opening and closing.

  In another aspect, the fourth existing column is provided on the opposite side of the first existing column with respect to the second existing column, and the length of the suspension rail is equal to or greater than the distance between the first existing column and the fourth existing column. Is set to In this case, in the second step, a new pillar is installed on the fourth existing pillar in addition to the first existing pillar and the second existing pillar. In a 3rd process, a suspension rail is fixed to the support part of each new pillar installed in the 1st existing pillar, the 2nd existing pillar, and the 4th existing pillar.

  In another aspect, the tip of the support portion is formed so as to be fitted to the upper end portion of each existing column.

  By the said structure, the connection of the upper end part of an existing pillar and the support part of a new pillar becomes easy compared with the case where it is performed, for example by welding.

  In another aspect, the first existing pillar and the second existing pillar are erected vertically to the installation surface. In the column main body, the length from the other end of the column main body to the base end of the support portion is equal to the height from the installation surface at the upper end of the existing column on which the new column is installed. The support portion extends in a direction orthogonal to the longitudinal direction of the column main body.

  With the above configuration, the suspension door is supported more stably.

  According to the present invention, the suspension door supported by the support portion via the suspension rail is disposed in parallel to this plane at a position away from the plane formed by the first existing pillar and the second existing pillar. Suspension doors can be installed on the fence. Moreover, since it is not necessary to remove the first existing pillar and the second existing pillar, the suspension door can be easily installed.

The bearing 27 has two plate-like members arranged in parallel with a space for arranging a roller 29 (see FIG. 16) therebetween. These plate-like members are provided so as to protrude from the side surface of the column main body 20 directly above the bearing 26, and a hole through which the rotation shaft of the roller 29 is inserted is formed.

  A stopper 30 is provided on the side surface of the column body 20 on the other end 22 side (see FIGS. 5 and 6). The stopper 30 is for restricting the movement of the suspension door 80 described later. Moreover, this stopper 30 is for connecting the other end 22 side of the column main body 20 of the newly installed column 11 and the first existing column 101, and is arranged in parallel with the support portion 40 described later (FIG. 5). In the present embodiment, the stopper 30 is formed so that the cross section in the direction orthogonal to the longitudinal direction has an L shape (see FIG. 6). A hole 31 through which the bolt 16 (see FIG. 16) is inserted is formed at the distal end side of the stopper 30.

  FIG. 8 is an enlarged view of the support part 40, (A) shows the support part 40 seen from the same direction as FIG. 5, and (B) shows the support part 40 seen from above.

  A support portion 40 is provided at one end 21 of the column body 20. The support portion 40 is connected to a support portion main body 41 that supports a suspension rail 90 (see FIG. 9), which will be described later, and an upper end portion 111 (see FIG. 15) of an existing column (here, the first existing column 101). Connecting portion 42. Although the support part main body 41 is being fixed to the column main body 20 by welding in this embodiment, you may be comprised by the column main body 20 and another member. The support part main body 41 is extended in the direction orthogonal to the longitudinal direction of the column main body 20 from the one end 21 side of the column main body 20 (refer FIG. 8 (A)).

  A pole 43 is erected in the central portion on the upper side of the support portion main body 41. The pole 43 supports a fence 98 (see FIG. 3) described later. A hanging tool 44 is provided at the lower central portion of the support body 41. The hanger 44 is for locking the hanger rail 90 (see FIG. 19).

  A connecting portion 42 is provided at the tip of the support portion main body 41 (the right end in FIG. 8). The connection part 42 is a cylindrical steel pipe whose axial direction is the longitudinal direction (vertical direction in FIG. 8A) of the column main body 20. The connecting portion 42 has a bottom 47 on its upper surface and opens downward. As will be described later, the upper end portion 111 of the first existing pillar 101 is inserted into the connecting portion 42 from this opening portion (see FIGS. 15 and 19). For this reason, the cross-sectional inner shape of the connection part 42 in the direction orthogonal to the longitudinal direction of the column main body 20 is circular according to the cross-sectional outer shape of the first existing column 101. Further, the inner diameter of the connecting portion 42 is set to be slightly larger than the outer diameter of the upper end portion 111 of the first existing column 101. Thus, the connection part 42 is formed so that the upper end part 111 of the 1st existing pillar 101 can be fitted. Further, the depth of the connecting portion 42 is such that the connecting portion 42 is not easily detached from the upper end portion 111 in a state where the upper end portion 111 of the first existing column 101 is inserted into the connecting portion 42 and is in contact with the bottom 47. Set to a depth of.

  A screw hole 48 having a female screw is formed in the side wall of the connecting portion 42 (see FIG. 8B). Three screw holes 48 are formed at equal intervals in the circumferential direction of the side wall of the connecting portion 42. A bolt 49 (see FIG. 19) is screwed into the screw hole 48 in a state where the upper end portion 111 of the first existing pillar 101 is inserted into the connecting portion 42. The connecting portion 42 is fixed to the first existing column 101 by pressing the side surface of the upper end portion 111 of the first existing column 101 by the tip of the bolt 49. That is, the new pillar 11 is connected to the upper end of the first existing pillar 101.

  As will be described later, the new pillar 11 described above is connected to the upper end portion 111 of the first existing pillar 101. Similarly, the new pillar 12 is connected to the upper end 112 of the second existing pillar 102, and the new pillar 14 is connected to the upper end 114 of the fourth existing pillar 104 (see FIGS. 12 and 13). The new pillar 12 is configured similarly to the new pillar 11 except that the new pillar 12 does not have the stopper 30. The new column 14 is configured in the same manner as the new column 11 except that the new column 14 does not have the stopper 30 and the pole 43. Therefore, detailed description of the new pillars 12 and 14 is omitted here.

  FIG. 9 is a diagram illustrating an external configuration of the suspension rail 90. The suspension rail 90 shown in FIG. 9 includes an upper wall 91, a side wall 92 bent at right angles from both sides of the upper wall 91, a lower wall 93 bent at right angles from the side wall 92 to the inside of the suspension rail 90, and And an inner wall 94 bent at a right angle from the wall 93 toward the upper wall 91. This suspension rail 90 is for supporting the runner 81 (refer FIG. 10) mentioned later. For this reason, the dimensions of the walls 91 to 94 of the suspension rail 90 are appropriately set according to the size of the runner 81.

  The suspension rail 90 is locked by the suspension tool 44 of each of the newly installed columns 11, 12, and 14. For this reason, the length of the suspension rail 90 is set to be not less than the distance d3 (see FIG. 1) between the first existing pillar 101 and the fourth existing pillar 104.

  10A and 10B are diagrams showing the structure of the runner 81, where FIG. 10A shows the front of the runner 81, FIG. 10B shows the side of the runner 81, and FIG. The runner 81 shown in FIG. 10 is for hanging the suspension door 80 on the suspension rail 90. In the present embodiment, three runners 81 are used to suspend the suspension door 80. The runner 81 has a runner body 82, a shaft portion 83, and a double roller 84. Two double rollers 84 are rotatably provided on the runner body 82. The shaft portion 83 is a columnar rod-like member extended from the runner body 82, and has an external thread on the outer peripheral surface.

  11A and 11B are diagrams showing the structure of the hanging door 80, where FIG. 11A shows the front of the hanging door 80 and FIG. 11B shows the upper surface of the hanging door 80. FIG. The suspension door 80 shown in FIG. 11 is provided with a fence 87 inside a frame 86 that is longer in the width direction than in the height direction. Three plates 89 are provided on the upper frame 88 constituting the frame 86. These plates 89 are fixed to both ends and the center of the upper frame 88 by welding, for example. Each plate 89 is formed with a screw hole having a female screw (see FIG. 11B). A hole for inserting the shaft 83 of the runner 81 is formed at a position corresponding to the screw hole of each plate 89 in the upper frame 88. The runner 81 is fixed to the suspension door 80 by screwing the shaft portion 83 of the runner 81 to the plate 89 (see FIG. 20).

  Hereinafter, the installation method of the hanging door 80 which concerns on this embodiment is demonstrated. FIG. 12 is a front view of the existing fence 100 after the first step.

  First, in the first step, as shown in FIGS. 1 and 12, the hinged door 110, the fence 106, and the third existing pillar 103 are removed from between the first existing pillar 101 and the second existing pillar 102. Specifically, after removing the hinged door 110 from the second existing pillar 102, the fence 106 is removed from the first existing pillar 101 and the third existing pillar 103. Then, the remaining third existing pillar 103 is cut leaving a portion installed in the ground. As a result, as shown in FIG. 12, the first existing pillar 101, the second existing pillar 102, the fourth existing pillar 104, and the fence 107 remain in the existing fence 100.

  FIG. 13 is a diagram showing the existing fence 100 after the second step. FIG. 14 is a schematic diagram of the existing fence 100 after the second step as viewed from above. FIG. 15 is a diagram illustrating a state in which the connecting portion 42 of the new pillar 11 is connected to the upper end portion 111 of the first existing pillar 101. FIG. 16 is a diagram showing the structure of the column main body 20 and the first existing column 101 after the second step, and (A) shows the column main body 20 and the first existing column 101 viewed from the same direction as FIG. (B) shows the column main body 20 and the first existing column 101 viewed from the direction of the arrow 71 in (A), and (C) shows the column main body 20 and the first existing column 101 viewed from the direction of the arrow 72. 14 schematically shows the fence 107, and in FIG. 16C, the one end 21 side of the new pillar 11 is omitted.

  In the second step, the new pillar 11 is installed on the first existing pillar 101, the new pillar 12 is installed on the second existing pillar 102, and the new pillar 14 is installed on the fourth existing pillar 104. Hereinafter, the operation of installing the new pillar 11 on the first existing pillar 101 will be specifically described. First, on the installation surface 120, the anchor bolt 23 is driven into a position where the hole 25 of the support plate 24 of the new pillar 11 is disposed. Since four holes 25 are provided in the support plate 24, four anchor bolts 23 are driven into the installation surface 120.

  Next, the new pillar 11 is arranged so that the connecting portion 42 is located immediately above the upper end 111 of the first existing pillar 101 (see FIG. 15), and the new pillar 11 is moved downward as it is. As a result, the upper end portion 111 of the first existing pillar 101 is inserted into the connecting portion 42. As described above, the length of the column main body 20 is set to be approximately equal to the distance from the installation surface 120 to the upper end of the first existing column 101. For this reason, in a state where the upper end portion 111 of the first existing column 101 is inserted into the connecting portion 42, the support plate 24 of the new column 11 contacts the installation surface 120. At that time, the anchor bolts 23 are inserted into the holes 25 of the support plate 24. Thereby, the new pillar 11 is restricted from moving in a direction other than the upward direction in the vertical direction. Then, a bolt insertion hole is formed at a position corresponding to the hole 31 of the stopper 30 in the first existing pillar 101, and the bolt 16 and the nut 17 are screwed together (see FIG. 16B). Thereby, the stopper 30 is fixed to the first existing pillar 101. As described above, when the new pillar 11 is installed on the first existing pillar 101, the support portion 40 of the new pillar 11 intersects the plane 70 formed by the first existing pillar 101 and the second existing pillar 102 (this implementation). It is in a state of being orthogonal) (see FIG. 14).

  Subsequently, as shown in FIG. 16, the roller 29 is rotatably attached to the bearing 27 of the pillar body 20 of the newly installed pillar 11, and the roller 28 is rotatably attached to the bearing 26 of the support plate 24. And the bearing 33 provided with the roller 32 which can rotate is fixed to the 1st existing pillar 101 so that the roller 29 and the roller 32 may face each other across the space where the suspension door 80 enters. The bearing 33 forms a through hole in the first existing column 101 and is fixed to the first existing column 101 using a bolt and a nut. For example, the bearing 33 is formed in the first existing column 101 by other methods such as welding. It may be fixed.

  Up to this point, the work of installing the new pillar 11 with respect to the first existing pillar 101 has been described, but in the same manner, the new pillar 12 is installed with respect to the second existing pillar 102 and the fourth existing pillar 104 is provided. On the other hand, a new pillar 14 is installed.

  In addition, the order which installs the new pillars 11, 12, and 14 is not limited to the above-mentioned order. That is, for example, the new pillar 12 is installed on the first existing pillar 101 after the new pillar 12 is installed on the second existing pillar 102, and then the new pillar 14 is installed on the fourth existing pillar 104. You may make it do.

  FIG. 17 is a front view of the existing fence 100 after the third step. FIG. 18 is a view of the existing fence 100 shown in FIG. 17 as viewed from above. FIG. 19 is an enlarged view of the periphery of the support portion 40 as viewed from the direction of the arrow XIX in FIG.

  In the third step, as shown in FIGS. 13 and 17 to 19, the suspension rail 90 is fixed to the new pillar 11, the new pillar 12, and the new pillar 14. Specifically, the suspension rail 90 is locked to the lifting tool 44 of the newly installed column 14 after being locked to the lifting tool 44 of the newly installed column 14, and is further locked to the lifting tool 44 of the newly installed column 11. As a result, the suspension rail 90 is stably supported by both the new pillars 11, 12, 14 and the existing pillars 101, 102, 104. In addition, the suspension rail 90 is arrange | positioned in the position away from the plane 70 in parallel with the plane 70 (refer FIG. 18).

  FIG. 20 is a diagram illustrating a state in which the suspension door 80 is suspended from the suspension rail 90.

  In the fourth step, the suspension door 80 is suspended from the suspension rail 90 as shown in FIG. Specifically, the double rollers 84 of the three runners 81 fixed to the upper frame 88 of the suspension door 80 are hooked on the lower wall 93 of the suspension rail 90. Thereby, the suspension door 80 is slidably supported with respect to the suspension rail 90 (refer FIG.2 and FIG.3).

  By the way, as for the support part 40, the hanging tool 44 is being fixed to the approximate center of the longitudinal direction. This support part 40 is arrange | positioned so that it may orthogonally cross with respect to the plane 70 formed with the 1st existing pillar 101 and the 2nd existing pillar 102 (refer FIG. 14). As a result, the lifting tool 44 is disposed at a position separated from the plane 70 by a distance corresponding to the distance between the connecting part 42 and the lifting tool 44 in the longitudinal direction of the support part 40 (see FIG. 4). As a result, the hanging door 80 is arranged in parallel with the plane 70.

  In the fifth step, three raising fences are installed. Specifically, the raising fence 98 is fixed to the poles 43 of the first existing pillar 101 and the second existing pillar 102 (see FIG. 2). Although not shown in the figure, a raising fence is also installed on the fence 107. Specifically, a pole similar to the pole 43 is installed on the connecting portion 42 of the new pillar 12 and the new pillar 14. And the fence for raising is fixed to these two poles. In addition, this fence is installed between two poles, and its upper end is approximately the same height as the upper end of the fence 98. By the way, although not shown in the drawing, an existing column and fence similar to the fourth existing column 104 and the fence 107 are provided at a position opposite to the second existing column 102 with respect to the first existing column 101. ing. A fence similar to that installed on the fence 107 is also installed between the existing pillar and the first existing pillar 101 in the same manner. By installing the three raising fences in this way, it is more effectively prevented that an intruder crosses the fence.

  Finally, tighten all bolts and nuts. First, a bolt 49 is screwed into the screw hole 48 of the connecting portion 42 of the new pillar 11 to fix the support portion 40 to the tip portion 111 of the first existing pillar 101. Then, the nuts 35 are screwed into the anchor bolts 23 protruding above the support plate 24 from the holes 25 of the support plate 24 of the new pillar 11. Thereby, the support portion 40 of the new pillar 11 is fixed to the upper end portion 111 of the first existing pillar 101, and the other end 22 of the column main body 20 of the new pillar 11 is fixed to the installation surface 120. This series of tightening operations is similarly performed on the new columns 12 and 14. The work in the fifth step may be performed in the second step described above. However, in order to assemble all members in a balanced manner, the work may be performed after the fourth step.

  As described above, according to the suspension door installation method according to the present embodiment, each of the existing columns 101 so that the support portion 40 is orthogonal to the plane 70 formed by the first existing column 101 and the second existing column 102. , 102, 104, the suspension door 80 is arranged in parallel with the plane 70. That is, the suspension door 80 is arranged so as not to be located on the same plane as the first existing pillar 101 and the second existing pillar 102. For this reason, the suspension door 80 can be installed on the existing fence 100. Further, since it is not necessary to remove the first existing pillar 101 and the second existing pillar 102 when installing the suspension door 80, the installation of the suspension door 80 is easy.

  Further, by installing the suspension door 80 instead of the hinged door 110, the opening width of the door is determined from the distance d2 between the third existing pillar 103 and the second existing pillar 102, so that the first existing pillar 101 and the second existing pillar 102 are provided. (See FIGS. 1 and 2). If the distance d1 is wider than the width of the vehicle, the vehicle can be passed by fully opening the suspension door 80. Moreover, since the hanging door 80 is installed instead of the hinged door 110, the door does not come in contact with an obstacle when opening and closing.

  In addition, although this embodiment demonstrated the case where the fence 106, the 3rd existing pillar 103, and the hinged door 110 were provided between the 1st existing pillar 101 and the 2nd existing pillar 102, the 1st existing pillar 101 was demonstrated. Only the fence may be provided between the second existing pillar 102 and the second existing pillar 102. In this case, it is only necessary to remove this fence in the second step of the present invention.

  In the present embodiment, the connecting portion 42 is fitted to the upper ends 111, 112, 114 of the existing pillars 101, 102, 104 to connect the support portion 40 to the existing pillars 101, 102, 104. As described above, the connection between the support portion 40 and the upper end portions 111, 112, and 114 of the existing columns 101, 102, and 104 may be performed by other methods such as screwing and welding of bolts and nuts.

  Further, the second existing pillar 102, the third existing pillar 103, the fences 106 and 107, and the hinged door 110 are removed, and a suspension door is installed between the first existing pillar 101 and the fourth existing pillar 104. Also good. In this case, the second existing pillar in the present invention corresponds to the fourth existing pillar 104.

  The method for installing a suspension door according to the present invention is applicable to a case where a fence is removed and a suspension door is installed.
