Description

Technical Field

[0001] The utility model relates to the technical field of finger-shaped plates, in particular to a temporary finger-shaped plate during the operation and maintenance period of a straddle-type rail transit. Background Art

[0002] The straddle-type monorail line is composed entirely of track beams, so there are a large number of joints (i.e. gaps) between the track beams. The joints between the track beams are the content that needs special consideration in the construction of the track beams. If not handled properly, the concrete at the end of the track beam will be crushed or the vehicle will not travel smoothly. Monorails at home and abroad generally use the method of installing finger plates at the end of the track beam to ensure the smooth passage of vehicles. The finger plates are steel plates shaped like fingers. They are installed on the top surface and both sides of the track beam end at positions corresponding to the running wheels, stabilizing wheels, and guide wheels. They are fixedly connected to the track beams through anchor bolts. At present, the finger plates on two adjacent track beams generally cooperate with each other in a symmetrical cantilever state on both sides. When the vehicle passes, the finger plates on both sides need to participate in the work to meet the requirements of the vehicle passing the joints smoothly. The straddle-type monorail needs to be operated during the day and can only be repaired during the night window period. After the anchor bolt is repaired, the concrete filled with it needs a certain amount of time to increase its strength and cannot immediately bear the force. However, vehicles will pass through the anchor bolt about 2 hours after the repair. At this time, the strength of the concrete filled with the anchor bolt cannot meet the strength requirements, which can easily cause the anchor bolt to be damaged by tension prematurely after the repair. Therefore, it is necessary to provide a temporary finger plate solution that can bear force on one side and meet the requirements of operation and maintenance period. Summary of the invention

Specifically, the first finger-shaped plate 11 and the second finger-shaped plate 12 are only used during the maintenance period of the second anchor bolt 72 of the maintenance track beam 21. After the strength of the concrete filled at the second anchor bolt 72 reaches the age, the first finger-shaped plate 11 and the second finger-shaped plate 12 are removed and replaced with permanent finger-shaped plates, wherein the working time of the first finger-shaped plate 11 and the second finger-shaped plate 12 is during the period when the concrete strength rises, and the concrete strength rise time takes about 3 to 5 days. The first finger-shaped plate 11 is fixedly mounted on the working surface of the maintenance track beam 21 near the gap 3, and the second finger-shaped plate 12 is fixedly mounted on the working surface of the adjacent non-maintenance track beam 22 near the gap 3. The first finger-shaped plate 11 corresponds to the second finger-shaped plate 12 and cooperates with each other. The top surface of the first finger-shaped plate 11 is flush with the working surface of the maintenance track beam 21, and the top surface of the second finger-shaped plate 12 is flush with the working surface of the non-maintenance track beam 22. The first finger-shaped plate 11 is located near the gap 3 and does not extend into the gap 3. The second finger-shaped plate 12 extends across the gap 3 to the position of the first finger-shaped plate 11 and fits with the surface of the first finger-shaped plate 11 to form a simply supported state. An elastic pad 6 is fixedly arranged between the bottom of the second finger-shaped plate 12 and the track beam, wherein the elastic pad 6 is made of rubber material. The thickness of the elastic pad 6 is 10 to 18 mm. In this embodiment, the thickness of the elastic pad 6 is 15 mm. The elastic pad 6 can reduce the angular stiffness of the second finger-shaped plate 12 and improve the applicability of the beam end angle. It is required that every 100 cm 2The static compressive stiffness of the elastic pad 6 is 5 to 15 kN / mm. The first finger-shaped plate 11 is fixedly mounted on the top working surface or the side working surface of the maintenance track beam 21, and the second finger-shaped plate 12 is fixedly mounted on the top working surface or the side working surface of the adjacent non-maintenance track beam 22. Specifically, the first finger-shaped plate 11 and the second finger-shaped plate 12 can be mounted on the top working surface of the maintenance track beam 21 and the non-maintenance track beam 22, and the first finger-shaped plate 11 and the second finger-shaped plate 12 can also be mounted on the two side working surfaces of the maintenance track beam 21 and the non-maintenance track beam 22.
