DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a side edge of two bridges arranged side by side, such as when a road bridge for widening is installed side by side on one side edge of an existing road bridge. The present invention relates to an expansion joint for bridges used for connection between them.

Conventionally, various types of expansion joints for bridges have been devised, but as shown in FIG. 3, most of these are installed at right angles to the bridge axis of a road bridge. .
This conventional expansion joint (1) is used to connect the ends of road bridges (2) arranged in the bridge axis direction, and a vehicle passes on the expansion joint (1) so as to intersect at right angles. .

By the way, in recent years, it has become common to expand the road width of existing road bridges and to connect rampways to elevated main roads during the construction of highways. It is necessary to install along the side edge of. Fig. 4 shows the case of expanding the road width. A road bridge (4) for widening is installed in parallel on one side edge of the existing road bridge (3), and an expansion joint (5) is provided between them. Is installed.

The expansion joint (5) installed in parallel with such a bridge shaft needs performance and characteristics different from those of the conventional expansion joint (1). That is, in the conventional expansion joint (1), the vehicle passes over the expansion joint (1) so as to cross at right angles, so that the weight of the vehicle directly acts on the expansion joint (1) for a very short time.
The force acting on is small. Further, the displacement between the bridges absorbed by the expansion joint (1) is almost only the displacement in the bridge axial direction caused by the expansion and contraction due to the temperature change of the road bridge (2). On the other hand, in the expansion joint (5) installed parallel to the bridge axis,
The vehicle does not run in a direction orthogonal to the expansion joint (5), but crosses diagonally above it or runs parallel to it. Therefore, since the weight of the vehicle acts on the expansion joint (5) for a long time and a large force directly acts on the expansion joint (5), the force acting on the expansion joint (5) is very different from the conventional one. Becomes In addition, the displacement between the bridges absorbed by the expansion joint (5) is almost the same as the displacement caused by the expansion and contraction due to the temperature change of the road bridge (2), and is the vertical displacement due to the vibration generated by the passage of the vehicle. The displacement is also larger than the conventional one.

In spite of the fact that the performance and characteristics required for expansion joints are very different as described above, the conventional expansion joints (1 ) Was used as it was. As a result, the expansion joint is often damaged due to insufficient strength, and even if the expansion joint is not damaged, the life is shortened, and there is a problem in durability.

(22) is a pair of lower plates, which are formed from strip-shaped metal plates in this embodiment, and are located near the center of the facing surfaces of the side edges (11a) (12a) of the road bridges (11) (12). The grooves (23) formed along the axial direction are attached to the bottom of each groove. The left and right side surfaces of a bar-shaped elastic member (24) having a rectangular cross section are fixed to the facing surfaces of the pair of lower plates (22). Therefore, the elastic member (24) is installed between the two lower plates (22). In addition, the anchor (25) is made of a reinforcing rod in which the side surface of the lower plate (22) opposite to the elastic member (24) is embedded in the side edge portions (11a) (12a) so as to be attached to the groove (23). It is made by sticking to.

The lower plate (22) is provided to firmly attach the elastic member (24) to the bottom of the groove (23), and the elastic member (24) is provided with the side edge portions (11a) (12a). This is because if they are directly adhered to each other, the adhesion between the elastic member (24) and the side edge portions (11a) (12a) will be weak, and if a tensile force is applied, they will easily peel off.
The method of fixing the lower plate (22) to the side edge portions (11a) (12a) is not limited to the above method.

A portion (26) of the side edge portions (11a) (12a) above the concave groove (23) projects in the horizontal direction from a portion (27) below thereof, and two upper portions (26). The distance between the facing surfaces of is very small. An upper plate (28) made of a strip-shaped metal plate bent in an L shape is attached to the facing surface of the upper portion (26) and the upper side surface of the groove (23) so as to cover the entire side surface. ing. The attachment to the upper part (26) of the upper plate (28) is performed by an anchor (29) made of a reinforcing bar whose side surface contacting the upper part (26) of the upper plate (28) is embedded in the upper part (26). It is made by sticking to.

A small gap (30) is formed between the side surfaces contacting the upper portion (26) of the two upper plates (28), and the gap (30) is filled with the elastic sealing material (31). .
In addition, the side surface of the upper plate (28) extending in the horizontal direction, that is, the end of the portion in contact with the upper side surface of the groove (23) is located at the upper edge of the lower plate (22) in the groove (23). Since the upper surface of the elastic member (24) is abutted and the upper surface of the elastic member (24) is slightly lower than the upper edge of the lower plate (22), the portion surrounded by the upper plate (28), the lower plate (22) and the elastic member (24) is A space is formed. In this space,
The elastic sealing material (32) is filled. These elastic sealing materials (31) and (32) are both used in this space and the gap (3
A sealant of urethane type or thiocol type is preferable because it prevents impurities from entering into 0). The lower surface of the elastic member (24) is slightly above the lower edge of the lower plate (22), and a gap is also formed between the lower side surface of the concave groove (23) and the elastic member (24).
