る。Detailed Description of the Invention The present invention relates to a support for a monorail girder, etc. that uses a girder member as a track and supports the end of the girder member fixedly or movably. This invention relates to a support that can resist overturning moments in the direction perpendicular to the bridge axis. Note that the present invention is not intended only for monorail girders, but any girder member used under the same conditions as monorail girders, regardless of whether it is a bridge or a structure, is covered by the present invention.

れる。 Generally, as shown in Figure 1, in a straddle type monorail girder (also called a track girder) G, the girder G is positioned on the pier B and Movable and fixed support devices S, each having a structure capable of escaping displacements such as expansion and contraction of the girder due to temperature changes and inclination (deflection) in a vertical plane due to the action of load, are arranged at both lower ends of the girder.

る。 On the other hand, such a straddle-type monorail girder has a narrow girder width compared to general bridge girder members, and has a virtually elongated rectangular cross section (or I-shaped cross section), and the parallel girders are Because they are constructed independently of each other (horizontal grooves such as diagonals cannot be installed between the girders), they are susceptible to the effects of wind loads and/or centrifugal force generated by vehicle traffic on the curved portions of the girders. , not only vertical loads but also horizontal loads (perpendicular to the bridge axis) (horizontal overturning loads)

ものである。 Furthermore, in accordance with Japanese Patent Application No. 55-55652, the present applicants have previously embedded and fixed a bottomed casing in a girder member with its opening facing downward, and inserted a columnar body fixed to a pier into the casing. We proposed a support that can be inserted through the casing and a bearing member and a guide member are arranged between the two (the casing and the columnar body) to effectively cope with the overturning moment. However, this method reduces the effective cross section of the upper girder member in which the casing is buried in the girder member, which poses problems in terms of strength. It is necessary.

なされたものである。 The present invention has been made in view of the above-mentioned circumstances, and while inheriting the technical idea of the above-mentioned prior art proposed earlier, its technical problem is to obtain support that allows for a more rational design. Therefore, the present invention was developed by focusing on the rigidity of the trapezoidal or trilateral shape and the fact that this shape is the most rational shape for supporting and transmitting loads as a support device for a monorail girder.

されてなる。 The monorail girder support of the present invention adopts the following configuration (technical means) in order to solve the above technical problem. That is, it consists of an upper shoe that is fixed to the lower surface of the girder member and a lower shoe that is fixed to the upper surface of the lower structure with a fixing means that is anchored to the lower structure. The legs face each other at right angles and open like legs, and a concave groove is formed in the bridge axis direction between the ceiling surface and the inner wall surface, and the lower shoe has a shape that fits into the concave groove of the upper shoe. The upper surface of the upper shoe is spaced apart from the ceiling surface of the upper shoe, and the outer surface of the outer shoe in the direction perpendicular to the bridge axis is spaced apart from the inner wall surface of the upper shoe, and the upper surface of the upper shoe is spaced apart from the ceiling surface of the upper shoe. A bearing member is disposed between the upper shoe and the upper surface of the lower shoe, and between the upper part of the inner wall surface of the upper shoe and the upper part of the outer surface of the lower shoe, and the upper part of the upper shoe in the direction perpendicular to the bridge axis. An upper guide member and a lower guide member are arranged between the lower part of the inner wall surface of the shoe and the lower part of the outer surface of the lower shoe, respectively, to cut off the transmission of force in the vertical direction.

能を有する。 With the above configuration, the present invention has the following effects.
The vertical load acting on the girder members of the monorail girder is transmitted from the upper shoe to the lower shoe via the bearing member, and the lower shoe has a substantially three-sided or ladder-shaped rigid structure with the bearing member at the apex. None, the vertical load is widely and evenly distributed and transmitted to the lower structure at the bottom in contact with the lower structure. In addition, the horizontal overturning load is transmitted to the lower shoe via the upper guide member and the lower guide member located diagonally from the split-shaped inner wall surface of the upper shoe. Only a small bearing force is required on the structure, and overturning moment is effectively prevented. Furthermore, the guide member does not transmit vertical force acting on the upper shoe, but simply contacts the upper shoe, thereby guiding the movement of the upper shoe that follows the movement of the upper structure, and preventing rotation of the upper shoe due to deflection of the upper structure. It can be smoothly released and has the function of maintaining the relative position of the upper shoe and the lower shoe with respect to the direction perpendicular to the bridge axis.
