Description

  The present invention relates to a method for manufacturing a road bridge joint and a method for reinforcing a seal at a road bridge joint.

  As a joint for road bridges, a pair of corrugated vertical plates arranged in a wavy shape in the seam longitudinal direction of the road bridge and facing each other so as to form corrugated gaps, and between the corrugated vertical plates It is generally known that a rubber seal plate is provided which has a bent portion at the center and has both side portions coupled to opposing inner surfaces of the corrugated vertical plates (see Patent Document 1).

  In such a joint, both side portions of the seal plate are coupled to the corrugated vertical plate by vulcanization adhesion. Further, this seal plate is also bonded to the corrugated vertical plate with an adhesive.

It is also known that both sides of the seal plate are fastened and fixed to the opposing inner surfaces of the corrugated vertical plate by a bolt via a press plate (see Patent Document 2).
Japanese Patent Publication No.57-25682 JP-A-6-41907

  However, even if the seal plate is vulcanized and bonded to a joint member such as the vertical plate, the adhesive force decreases due to aging, so the seal plate partially peels from the joint member. There is a problem of creating a gap between the two. In particular, in the case of a corrugated vertical plate, the seal plate has a portion extending in a direction orthogonal to the bridge axis direction and a portion extending obliquely with respect to the bridge axis direction. There is a problem that the seal plate is easily peeled off from the vertical plate at the portion where the contact is formed. That is, in the oblique portion, a shearing force is applied to the seal plate as the road bridge body expands and contracts, and therefore the seal plate is easily twisted and peeled off from the vertical plate.

  On the other hand, when the seal plate is joined to the joint member using a presser plate and a bolt, the problem of peeling of the seal plate due to the aging change is solved, but the gap between both joint members is narrowed by the thickness of the presser plate. Therefore, the allowable expansion / contraction amount of the joint becomes small. Moreover, it is necessary to tighten the bolt in a state where the presser plate is pressed against the seal plate so as not to be displaced, and there is a problem that the mounting operation of the seal plate becomes complicated. In addition, since an additional holding plate is required, the number of parts increases and the cost of the joint increases.

  When the joint member is a corrugated vertical plate, it is necessary to form the presser plate in a corrugated manner. However, a dimensional error or a shape mismatch is likely to occur between the vertical plate and the presser plate, and the seal plate is It becomes difficult to press the plate without a gap, and the cost of the press plate increases.

  In FIG. 1, 1 is a joint installed at the joint of the road bridge, and 2 and 2 are floor slabs (road bridge main body) facing each other with a gap 3 between them. Notches 4, 4 are formed at the ends of the floor slabs 2, 2 by boxing or the like, the joint 1 is arranged in the center between the notches 4, 4, and the post-cast concrete 5 is provided on both sides of the joint 1. 5 is cast. Reference numeral 6 denotes a dam plate provided to prevent leakage of the concrete into the gap 3 when the post-cast concrete 5 is placed, and reference numeral 7 denotes a pavement.

  The joint 1 includes a pair of steel vertical plates 8 and 8 and a rubber seal plate 9 as joint members. The vertical plates 8 and 8 are formed in a corrugated shape extending in a wave shape in the seam longitudinal direction, and are arranged so as to form a corrugated gap 10. The seal plate 9 is interposed in the corrugated space 10 between the vertical plates 8 and 8, and the center portion is formed in a U-shape that is bent downward, and both side portions are formed on the inner surfaces facing both the vertical plates 8 and 8.

  Hereinafter, the connection by the tapping screw 13 will be specifically described based on some embodiments.

<Embodiment 1>
This embodiment relates to a method for manufacturing the joint 1, and the joint 1 is manufactured by the following steps.

  A. Both side portions of the seal plate 9 are bonded to the opposing inner surfaces of the two vertical plates 8 and 8 by vulcanization adhesion. This vulcanization adhesion is performed over the entire length of the vertical plate 8 in the seam longitudinal direction, thereby connecting the vertical plate 8 and the seal plate 9 in a watertight state.

  B. As shown in FIG. 3, the drill 16 attached to the electric rotary machine 15 continuously penetrates the vertical plate 8 and the side portion of the seal plate 9 (the portion bonded to the vertical plate 8) from the seal plate 9 side. A pilot hole 17 is formed. The formation of the pilot hole 17 is performed on both the vertical plates 8 and 8.

  C. As shown in FIG. 4, the screw driver 18 is attached to the electric rotating machine 15, and the tapping screw 13 is screwed into the prepared hole 17 from the sealing plate 9 side, whereby the side portion of the sealing plate 9 is vertically moved by the tapping screw 13.

  The attachment of the bottom plate 11 and the anchor 12 may be performed before the process A, between the process A and the process B, or between the process B and the process C.

  Moreover, although the pilot hole 17 was formed horizontally in the said embodiment, you may form so that it may go diagonally downward.

  In the above embodiment, the pilot hole 17 is formed and then tightened with the tapping screw 13. However, without forming the pilot hole, the drilling tapping screw that simultaneously performs drilling and screwing is used to seal the seal plate 9. The side part may be fastened to the vertical plate 8.

  Therefore, according to this embodiment, since both side portions of the seal plate 9 are vulcanized and bonded to the vertical plates 8 and 8 on both sides over the entire length, a high adhesive force is obtained and the sealing performance is enhanced. Further, the side portion of the seal plate 9 is not only vulcanized and bonded, but is also fastened to the vertical plate 8 by the tapping screw 13, so that the bonding strength to the vertical plate 8 is further increased, and the adhesive force is assumed due to secular change. Even if it becomes weak, it is avoided that the sealing plate 9 peels from the vertical plate 8, and a sealing property can be ensured over a long period of time.

  Moreover, since the head portion of the tapping screw 13 compresses the side portion of the seal plate 9 and sinks into the side portion, the protrusion to the corrugated clearance 10 becomes little or hardly protrudes, and the allowable expansion and contraction amount of the joint 1 Can be avoided.

  Thus, the work after the seal plate 9 is bonded to the vertical plate 8 is only the formation of the pilot hole 17 by the drill 16 and the screwing of the tapping screw 13, and when the drilling tapping screw is used, the pilot hole is also formed. This eliminates the need for easy manufacture of the joint 1.

<Embodiment 2>
This embodiment relates to a method for manufacturing the joint 1 shown in FIG. 5, and the both ends of the seal plate 9 are notched so that a gap is formed between the inner surface of the vertical plate 8. The sealing material 21 is filled. The joint 1 is manufactured by the following steps.

  A. The both sides of the seal plate 9 are temporarily fixed to the opposing inner surfaces of the two vertical plates 8, 8 with an adhesive or the like.

  B. Similar to the first embodiment, the pilot hole 17 that continuously penetrates the vertical plate 8 and the side portion of the seal plate 9 is formed by a drill. The formation of the pilot hole 17 is performed on both the vertical plates 8 and 8.

  C. As shown in FIG. 6, the screw driver 18 is attached to the electric rotating machine 15, and the tapping screw 13 is screwed into the prepared hole 17 from the side of the sealing plate 9, whereby the side portion of the sealing plate 9 is vertically moved by the tapping screw 13. Fasten to plate 8. The side of the seal plate 9 is pressed against the vertical plate 8 by the head of the tapping screw 13. Tightening with the tapping screw 13 is performed on both sides of the seal plate 9.

  D. As shown in FIG. 5, the bottom plate 11 and the anchor 12 are attached to the vertical plates 8 and 8.

  E. A sealing material 21 is filled over the entire length of the seal plate 9 in the gap (notch portion 20) between the inner surface of the vertical plate 8 and the upper end of the side portion of the seal plate 9.

  Thus, the manufacture of the joint 1 is completed. In FIG. 6, the vertical plate 8 is not illustrated in a wave shape, and the bottom plate 11 and the anchor 12 are not illustrated.

  The attachment of the bottom plate 11 and the anchor 12 may be performed before the process A, between the process A and the process B, or after the process E.

  In the above embodiment, the pilot hole 17 is formed and then tightened with the tapping screw 13. However, without forming the pilot hole, the drilling tapping screw that simultaneously performs drilling and screwing is used to seal the seal plate 9. The side part may be fastened to the vertical plate 8.

  Therefore, according to this embodiment, the sealing material 21 ensures the sealing performance between the vertical plate 8 and the seal plate 9. Further, since both side portions of the seal plate 9 are fastened to the vertical plates 8 and 8 on both sides by the tapping screws 13, the bonding strength to the vertical plate 8 is increased, and the seal plate 9 is prevented from peeling from the vertical plate 8. The sealing property can be ensured over a long period of time.

  Thus, in this embodiment, since the sealing property 21 is used to secure the sealing performance, vulcanization adhesion of the seal plate 9 to the vertical plate 8 is not necessary, and the seal plate 9 is temporarily attached to the vertical plate 8. The work after stopping is only the formation of the pilot hole 17 by the drill 16 and the screwing of the tapping screw 13, and when the drilling tapping screw is used, the formation of the pilot hole becomes unnecessary, and the joint 1 can be easily manufactured. .

  Moreover, since the head portion of the tapping screw 13 compresses the side portion of the seal plate 9 and sinks into the side portion, the protrusion to the corrugated clearance 10 becomes little or hardly protrudes, and the allowable expansion and contraction amount of the joint 1 Can be avoided.

<Embodiment 3>
The present embodiment is performed after the joint 1 in which both side portions of the seal plate 9 are bonded to the vertical plates 8 and 8 on both sides is installed at the joint portion of the road bridge, or is already installed at the joint portion of the road bridge. The present invention relates to a method for reinforcing a seal at a construction site.

  That is, as shown in FIG. 7, a pilot hole 17 that continuously penetrates the vertical plate 8 and the side portion of the seal plate 9 is formed, and the tapping screw 13 is inserted into the pilot hole 17 on the side of the seal plate 9 (corrugated clearance). 10), the side portion of the seal plate 9 is fastened to the vertical plate 8 by the tapping screw 13. The formation of the pilot hole 17 and the fastening with the tapping screw 13 are performed on both sides of the seal plate 9.

  The formation of the pilot hole 17 and the screwing of the tapping screw 13 are performed obliquely downward so that the electric rotary machine 15 does not interfere with the road bridge.

  In the above embodiment, the pilot hole 17 is formed and then tightened with the tapping screw 13. However, without forming the pilot hole, the side portion of the seal plate 9 is formed by the drilling tapping screw that performs drilling and screwing at the same time. May be fastened to the vertical plate 8.

  Therefore, according to the present embodiment, since both side portions of the seal plate 9 are fastened to the vertical plate 8 by the tapping screw 13, the bonding strength of the seal plate 9 to the vertical plate 8 is increased. Even if the adhesive force with the seal plate 9 is weakened, the seal plate 9 can be prevented from being peeled off from the vertical plate 8, and the sealing performance can be secured for a long period of time.

  Alternatively, by applying this embodiment to the existing joint 1 in which the adhesive force between the vertical plate 8 and the seal plate 9 is weakened, the adhesive force is reinforced to improve the sealing performance and to extend the life of the joint 1. Can do.

  Moreover, since the head portion of the tapping screw 13 compresses the side portion of the seal plate 9 and sinks into the side portion, the protrusion to the corrugated gap 10 becomes little or hardly protrudes, and the allowable expansion and contraction amount of the joint 1 Can be avoided.

  Thus, the work after the seal plate 9 is bonded to the vertical plate 8 is only the formation of the pilot hole 17 by the drill 16 and the screwing of the tapping screw 13, and when the drilling tapping screw is used, the pilot hole is also formed. It becomes unnecessary and is easy to install.
