JP 2006-299786 A [E03F 5/04]

  However, when the surface of the structure is rehabilitated by the rehabilitation panel member, the interval provided between them is about 5-10 mm. For this reason, when the bolt is provided at a position deeper from the edge of the rehabilitation panel member, it is difficult to insert the operator's finger up to the position of the bolt. It is difficult to install. Moreover, since the spacer of patent document 1 has a cylindrical shape, when attaching a volt | bolt to a spacer, it is hard to have and it is difficult to use it.

  Therefore, a main object of the present invention is to provide a spacer that can be easily attached to a bolt provided at a predetermined position deep from the edge of the panel.

  The present invention employs the following configuration in order to solve the above problems. Note that reference numerals in parentheses, supplementary explanations, and the like indicate correspondence relationships with embodiments described later to help understanding of the present invention, and do not limit the present invention in any way.

  The invention of claim 1 is a spacer used when a panel having a bolt hole formed at a predetermined position at a predetermined distance from an edge is fixed to the surface of a structure with a bolt, and has an inner diameter larger than the outer diameter of the bolt. The first opening that communicates with the first hole is formed on one end side, the grip portion is formed on the other end side, and the grip portion can be gripped and positioned at a predetermined position. This is a spacer.

  In the invention of claim 1, the spacer (10) is formed on the surface (46) of the structure (46) with the panel (30) in which the bolt hole (44) is formed at a predetermined position deeper than the end edge (40). When bolted, it is attached to the bolt (48) in order to provide a gap between the panel and the surface of the structure. The spacer has a first hole (12) into which a bolt is inserted, and is formed in a substantially rectangular plate shape by a soft member such as synthetic rubber. The spacer is formed with a first opening (18) leading to the first hole on one end (14) side and a gripping portion (22) on the other end (16) side, so that the operator holds the spacer. It is formed so that the part can be gripped and positioned at a predetermined position, that is, the first hole can be placed in the vicinity of the bolt or the bolt. For example, after attaching the bolt to the surface of the structure, when attaching the spacer to the bolt, the operator may hold the holding portion and insert the bolt into the first hole through the first opening.

  According to the first aspect of the present invention, since the first opening leading to the first hole is formed on one end side and the gripping portion is formed on the other end side, the bolt attached at a position recessed from the edge of the panel Can also be easily attached.

  The invention of claim 2 is dependent on the invention of claim 1, and the grip portion has a length longer than a length corresponding to the predetermined distance.

  In the invention of claim 2, the gripping part (22) has a length longer than the length corresponding to the distance from the edge (40) of the panel (30) to the bolt hole (44). Therefore, it can be easily attached to the bolt (48) attached at a position deep from the edge of the panel and attached so that the operator's finger does not enter.

  The invention of claim 3 is dependent on the invention of claim 1 or 2, and the second hole is formed in the grip portion.

  In the invention of claim 3, the second hole (60) is formed in the grip portion (22) of the spacer (10). The second hole has an inner diameter different from that of the first hole (12), for example. Therefore, the spacer can be used also for two types of bolts (48) having different outer diameters.

  The invention of claim 4 is dependent on any one of claims 1 to 3, and has a Shore A hardness of 60 or more and 90 or less in accordance with JIS-K6253.

  In the invention of claim 4, the hardness of the spacer (10) is such that the Shore A hardness in accordance with JIS-K6253 is 60 or more and 90 or less, and preferably the Shore A hardness is 70 or more and 80 or less. As a result, the spacer has moderate flexibility and shape restoration. Therefore, the spacer can be easily attached to the bolt (48) through the opening (18, 62).

  According to the present invention, since the first opening leading to the first hole is formed on one end side and the gripping portion is formed on the other end side, the spacer provided on the bolt provided at a position recessed from the edge of the panel is also provided. Can be easily attached.

  The above object, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

  Referring to FIG. 1, a spacer 10 according to an embodiment of the present invention is configured such that a renovated panel member 30 having a bolt hole 44 formed at a predetermined position at a predetermined distance from an edge 40 is attached to a surface of a structure by a bolt 48. Used when fixing to 46. Specifically, the spacer 10 has a space between the structure surface 46 and the rehabilitation panel member 30 when the surface 46 of the structure such as a deteriorated open channel is rehabilitated by the rehabilitation panel member 30. Alternatively, the rehabilitation panel member 30 is attached to the bolt 48 in order to prevent the rehabilitation panel member 30 from being bent when the rehabilitation panel member 30 is fixed to the surface 46 of the structure by the bolt 48.

  As shown in FIGS. 2 and 3, the spacer 10 is formed in a substantially rectangular plate shape by a corrosion-resistant soft member including a synthetic rubber such as SBR (styrene butadiene rubber) or CR (chlorobrene rubber). The The dimensions of the spacer 10 are, for example, a width of 25 mm, a length of 45 mm, and a height of 5 mm. Further, the hardness of the spacer 10 is set such that the Shore A hardness conforming to JIS-K6253 is set to 60 or more and 90 or less, and preferably the Shore A hardness is set to 70 or more and 80 or less.

  The spacer 10 has a substantially circular first hole 12 in plan view. The inner diameter of the first hole 12 is, for example, 13 mm, and is set larger than the outer diameter r1 (see FIG. 1) of the bolt 48 for fixing the rehabilitation panel member 30 described later to the structure surface 46 of the structure. A substantially triangular first opening 18 is formed on the one end 14 side of the spacer 10 in a plan view that leads to the first hole 12. The opening interval at the end 20 on the first hole 12 side of the first opening 18 is set smaller than the outer diameter of the bolt 48. Further, a gripping portion 22 is formed on the other end 16 side of the spacer 10, and this gripping portion 22 is a portion that is gripped by an operator when the spacer 10 is attached to the bolt 48. The length L1 of the grip portion 22 is, for example, 26 mm, and is set to a length longer than a length corresponding to a distance d1 from an edge 40 of the renovated panel member 30 to be described later to the bolt hole 44.

  For example, the rehabilitation panel member 30 of Patent Document 1 shown in FIG. The rehabilitation panel member 30 includes a main body 36 having a first end 32 and a second end 34, and joins the adjacent first end 32 and second end 34 to form a rehabilitation panel.

  The main body 36 of the rehabilitation panel member 30 has a rectangular plate shape, and a recess 38 is provided on the second end 34 side. The recessed portion 38 has a substantially “J” -shaped cross-sectional shape, and an end portion thereof becomes an end edge 40 of the renovated panel member 30. Bolt holes 44 for inserting bolts 48 for fixing the rehabilitated panel member 30 to the surface 46 of the structure are formed in the bottom surface portion 42 of the hollow portion. A distance d1 from the end edge 40 of the rehabilitation panel member 30 to the bolt hole 44 is, for example, 25 mm, which is shorter than the length L1 of the grip portion 22 of the spacer 10. Further, the outer diameter r1 of the bolt 48 is, for example, 12 mm, which is slightly smaller than the first hole 12 of the spacer 10.

  When the rehabilitation panel member 30 is attached to the surface 46 of the structure at an interval using the spacer 10 of this embodiment, first, the rehabilitation panel member 30 is temporarily placed at the attachment position, and the rehabilitation panel member 30 is then placed. The position of the surface 46 of the structure corresponding to the position of each bolt hole 44 provided in is confirmed, and the embedded anchor 50 is installed at those positions. Next, the bolt 48 is inserted into the embedded anchor 50 through the bolt hole 44 of the rehabilitation panel member 30, and the bolt 48 is temporarily fixed by hand tightening.

  In this temporarily fixed state, as shown in FIG. 5, the spacer 10 is pushed from the side surface of the bolt 48, and the bolt 48 is inserted into the first hole 12 through the first opening 18. The spacer 10 is attached to 48. When the spacer 10 is attached to the bolt 48, for example, the first opening 18 of the spacer 10 is expanded in the width direction, and the opening interval at the end 20 of the first opening 18 is increased to the outer diameter r1 or more of the bolt 48. deep. If the spacer 10 is attached to the bolt 48 before the first opening 18 returns to the original state by the shape restoration function of the spacer 10, the first opening 18 can be formed without requiring a large force. Thus, the spacer 10 can be easily attached to the bolt 48. In addition, after the first opening portion 18 returns to the original state, the opening interval at the end portion 20 becomes smaller than the outer diameter r1 of the bolt 48, and the spacer 10 is prevented from coming off.

  Thereafter, the bolt 48 is finally tightened using a wrench or the like, thereby completing the attachment of the renovated panel member 30 to the surface 46 of the structure. At this time, if there is a recess in a part of the surface 46 of the structure, and there is a place where the interval between the rehabilitation panel member 30 and the surface 46 of the structure is wider than other places, it is provided in that place. A plurality of, for example, two spacers 10 may be attached to the bolt 48 that is formed.

  After one rehabilitated panel member 30 is attached to the structure surface 46, the other rehabilitated panel member 46 is sequentially connected to the rehabilitated panel member 46 that has been attached, and the entire rehabilitated panel member 46 extends over the entire surface 46 of the structure. The rehabilitation panel member 30 is attached (see FIG. 1). Then, a backfilling material such as mortar is injected into the space between the rehabilitation panel member 30 provided by the spacer 10 and the structure surface 46, and finishing work such as coking treatment of the end portion is appropriately performed. End rehabilitation work.

  As described above, the first opening 18 communicating with the first hole 12 is formed on the one end 14 side of the spacer 10 and the gripping portion 22 is formed on the other end 16 side. Can be positioned at a predetermined position, and the spacer 10 can be easily attached to the bolt 46 attached at a predetermined position deep from the end edge 40 of the rehabilitation panel member 30.

  In addition, since the length of the grip portion 22 is longer than the length corresponding to the distance from the edge 40 of the rehabilitation panel member 30 to the bolt hole 44, the bolt 48 attached so that the operator's finger cannot enter is provided. Also, the spacer 10 can be easily attached. Furthermore, since the spacer 10 is formed in a substantially rectangular plate shape, it is easier to hold and attach to the bolt 48 than a cylindrical spacer.

  Further, the spacer 10 is formed of a soft member such as synthetic rubber, and its hardness is set to 60 to 90 in Shore A hardness according to JIS-K6253, preferably 70 to 80 in Shore A hardness. No. 10 has moderate softness and shape recovery. That is, even if the spacer 10 is pressed from above by bolting the rehabilitation panel member 30 or the like, the spacer 10 has a hardness that does not dent, and the first opening 18 is expanded in the width direction by the hand of the operator. It has a softness that can be Moreover, if the hand is released in a state where the first opening 18 is widened in the width direction, it has a shape restoring property that returns to the original state after a few seconds.

  As another example, as shown in FIG. 6, the spacer 10 may further include a second hole 60 and a second opening 62. Since it is the same as the spacer 10 shown in FIGS. 2 and 3 except that the second hole 60 and the second opening 62 are provided, common portions are denoted by the same reference numerals, and redundant description is omitted.

  The spacer 10 shown in FIG. 6 has a substantially circular second hole 60 in plan view. The second hole 60 is provided in the grip portion 22, and the inner diameter R2 is set to a size different from, for example, the inner diameter R1 (13 mm) of the first hole described above. Specifically, the inner diameter R2 of the second hole 60 is, for example, 10.5 mm, and the second bolt (not shown) having an outer diameter different from the outer diameter r1 of the bolt 48 described above is replaced with the rehabilitation panel member 30. When it is used when attaching to the surface 46 of the structure, it is set to adapt to the outer diameter of the second bolt. In addition, a substantially triangular second opening 62 is formed on the other end 16 side of the spacer 10 in a plan view leading to the second hole 60. The opening interval at the end 64 on the second hole 60 side of the second opening 62 is set smaller than the outer diameter of the second bolt. In addition, the one end 14 side of the spacer 10 serves as a second grip portion 66 that is gripped when the operator attaches the spacer 10 to the second bolt using the second hole 60. The length L2 of the second grip 66 is set to a length corresponding to the distance from the edge 40 of the rehabilitation panel member 30 to the bolt hole to which the second bolt is attached, for example.

  As described above, the second hole 60 having an outer diameter different from that of the first hole 12 is provided in the grip portion 22, and the second opening 62 communicating with the second hole 60 is provided. It can be used for two types of bolts 48 having a diameter.

  However, the second opening 62 that communicates with the second hole 60 is not necessarily provided, and the second opening 62 that communicates with the second hole 60 may not be provided as illustrated in FIG. 7. In this case, since the second bolt already driven into the surface 46 of the structure cannot be inserted into the second hole 60, the second bolt is inserted into the second hole 60 and then the second bolt is inserted into the structure. It is necessary to drive into the surface 46 of

  Although not shown in the drawings, the length of the gripping portion 22 is not necessarily longer than the length corresponding to the distance d1 from the end edge 40 of the renovated panel member 30 to the bolt hole 44. For example, when there is an interval between the rehabilitation panel member 30 and the surface 46 of the structure that allows the operator's finger to enter, the length of the grip portion 22 can be made shorter than the distance d1. .

  In each of the above-described embodiments, the spacer 10 is formed of a soft member such as synthetic rubber, but is not limited thereto. For example, the spacer 10 can be formed of semi-rigid vinyl chloride. Further, when the spacer 10 is thin, polyethylene or the like can be used. In other words, the spacer 10 is soft enough to expand the openings 18 and 62 in the width direction by the operator's hand, and has a shape restoring property that returns to its original shape when the operator releases the hand. As long as it is formed by.

  It should be noted that the specific numerical values such as the dimensions of the spacer 10 mentioned above are merely examples, and can be appropriately changed as necessary, for example, according to the type of the rehabilitation panel member 30.
