Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a support structure that can elastically support a monorail girder in a stable state.

[Prior art]

Conventionally, as a support structure for a monorail girder, as shown in FIGS. Each metal catch 13 is placed on a support base 1 such as a bridge pier or abutment via a liner plate 14, and a metal lower shoe 15 is placed on each metal catch 13 at intervals in the direction.
The stopper member 16 is placed across the arcuate support surface of the support base 1 and fixed to the upper part of the support base 1 through the locking hole 1 provided in the center of the lower shoe 15.
7, and insert an anchor bolt 18 across the support base 1, the metal seat 13, the liner plate 14, and the metal lower shoe 15. The legs 21 provided on both sides of the metal upper shoe 20 in the width direction of the metal upper shoe 20 are connected to the groove-shaped protrusions 19 provided on both sides of the metal lower shoe 15 in the width direction of the girder. A support structure is known in which a pin 24 is inserted into a long hole 22 provided in the groove-shaped protrusion 19 and a circular hole 23 provided in the leg 21.

However, this support structure is large, heavy, and expensive, and the construction is complicated.
Furthermore, there is no buffering ability for vertical loads, overturning moments, and lateral movement forces that act on the monorail girder 5, and as a result, large vertical loads, overturning moments, and lateral movement forces are excessively concentrated on the support structure and support platform, which act on the monorail girder 5 with impact. There is a problem in that stress acts and has an adverse effect on strength.

〔Example〕

Next, this invention will be explained in detail using illustrated examples.

1 to 5 show an embodiment of this invention, in which a metal frame type substrate 2 having a rectangular or rectangular opening 25 on the upper surface of a support base 1 made of a concrete abutment or abutment. is placed on the support base 1, the lower part of the lower shoe 4 made of a laminate of the rubber layer 3 and the metal plate 26 is fitted into the opening 25 of the metal frame substrate 2, and the upper part is placed on the support base 1. The metal upper shoe 6 to which the anchor reinforcing bar 27 is fixed is
It is fixed to the lower part of the monorail girder 5 made of a PC girder, and side opening recesses 28 for inserting clip tips are provided on both sides of the metal upper shoe 6 in the girder width direction.

Lower side surface 7 and intermediate upper surface 8 of metal upper shoe 6
The metal clip 9, which has a supporting surface facing the support surface and a reinforcing rib 29, is placed on the upper surface of both sides of the metal frame type substrate 2 in the girder width direction, and the tip of the metal clip 9 is provided with a metal frame substrate 2. The through holes of the metal frame substrate 2 and the metal clip 9 are inserted into the protrusion of the anchor bolt 11 which is inserted into the side opening recess 28 of the upper shoe 6 and fixed to the support base 1 in advance, and A rubber support material 12 is interposed between the lower side surface 7 and intermediate upper surface 8 of the metal upper shoe 6 and the support surface of the metal clip 9, and the anchor bolt 11, the metal frame type base plate 2, and the metal clip A rubber sleeve 3 is placed between the through hole 9
0 is interposed therebetween, and the metal frame-shaped substrate 2 and the metal clip 9 are tightened and fixed by a nut 31 screwed into the upper end of the anchor bolt 11. Steel clip receiving members 10, which face the side surfaces and both front and rear surfaces of the metal clip 9, are placed on the upper surface of the metal frame-shaped substrate 2 and are integrally welded.

In the case of the support structure of this invention, the deflection and expansion/contraction of the monorail girder 5 are dealt with by elastic compression deformation and shear deformation of the rubber layer 3 in the lower shoe 4. In addition, when a monorail car runs at high speed on the monorail girder 5 in a curved section, a large lateral pressure acts on the upper part of the monorail girder 5, and this lateral pressure is caused by the lateral movement force of the entire monorail girder 5 and the monorail girder 5. This acts as an overturning moment for the girder 5, but in the support structure of this invention, for example, when a large lateral pressure acts on the left side of the upper part of the monorail girder 5, the rubber layer acts as an overturning moment for the monorail girder 5. 3 and the left side rubber support 12 by the compressive elasticity of the horizontal part, and the lateral movement of the entire monorail girder 5 is countered by the compressive elasticity of the vertical part of the right rubber support 12.

Therefore, the overturning moment and the lateral movement force are supported while being buffered, and excessive concentrated stress does not act on the support structure.

When this invention is implemented, the metal frame base plate 2, the metal upper shoe 6, and the metal clip 9 are made of, for example, steel or cast iron. Further, it is preferable to fix the rubber support member 12 to the metal clip 9 in advance with an adhesive or the like.

An anchor box having a female thread may be embedded and fixed in the support base 1, and the lower male thread of the anchor bolt 11 having male threads on both upper and lower sides may be screwed into the female thread of the anchor box. This invention can also be applied to the support structure of steel monorail girders. In this case, the metal upper shoe 6 may be fixed to the steel monorail girder with bolts or the like.

[Effect of idea]

According to this invention, since the lower part of the lower shoe 4 having the rubber layer 3 is fitted into the opening 25 of the metal frame type substrate 2 placed and fixed on the upper surface of the support base 1, the support base The lower part of the lower shoe 4 placed on the upper surface of the lower shoe 4 can be firmly fixed by a simple means so as not to move in the horizontal direction, and the lower part of the metal upper shoe 6 placed on the lower shoe 4 can be Since a rubber support material 12 is interposed between the lower side surface 7 and the intermediate upper surface 8 on both sides in the width direction of the girder and the support surface of the metal clip 9 fixed by the anchor bolt 11, When an overturning moment is applied to the monorail girder 5 due to the lateral pressure of the monorail car, the intermediate upper surface 8 of the metal upper shoe 6 is removed by the metal clip 9 via the rubber support 12.
Since the monorail girder 5 is supported, the overturning moment of the monorail girder 5 that acts suddenly can be buffered and supported by the rubber support material 12 and also buffered and supported by the rubber layer 3 of the lower shoe 4. When lateral pressure in the width direction of the girder suddenly acts on the girder 5, the lateral pressure is buffered and supported by the metal clip 9 via the rubber support material 12 and the lower side surface 7 of the metal upper shoe 6. Therefore, it is possible to prevent concentrated stress from acting on the support structure and the support base 1. Furthermore, the metal clip 9 is supported by a clip receiving member 10 that is integrally provided on the metal frame type substrate 2. Since the metal frame substrate 2 and the metal clip 9 are fixed by a common anchor bolt 11, the structure is simple and construction is easy. It will be done.
