Background
Subways have become important transportation means in cities today, and thousands of people take the subways every day. Meanwhile, subway platform doors are widely used, almost all subway stations are provided with the platform doors, and every passenger taking the subway can pass through the platform doors, which means that the passengers can step on the doorsills of the platform doors. Because the potential difference that has been produced because of stray current and static exists between train, platform door, the platform, when people or object pass through the platform door, contact train or platform when contacting the threshold, the current that produces because of the potential difference can give other people and cause uncomfortable sense or injury, also can produce the destruction effect to the object.
The integral ground insulation of the existing subway platform door cannot be realized by all platform doors, so that the insulation of the threshold needs to be separately processed. In the conventional doorsill insulation, only surface treatment such as oxidation, painting, film pasting and the like is performed, so that the doorsill is easily damaged by passing objects, metal heels and the like, the service life is extremely short, and the purpose of long-term effective insulation cannot be achieved.
Therefore, an insulating threshold structure for a subway platform door, which has a long service life, a good insulating effect, a simple structure and convenience in installation, becomes a goal pursued by those skilled in the art.

The invention adopts the metal threshold body and the insulated threshold to form the threshold of the subway platform door; therefore, the insulating composite doorsill is formed, the insulating doorsill is embedded in the bottom of the metal doorsill body and is positioned at the position of the bottom supporting part, so that insulation is formed between the doorsill, the bottom supporting part of the doorsill and the stand column.
The insulating threshold and the metal threshold body are bonded, and the insulating threshold and the metal threshold body are firmly connected together in a screw fixing mode at two sides of the section bar.
After the metal threshold body and the insulating threshold are compounded, the metal threshold body is consistent with the traditional threshold, and the structural strength and other use performances are fully ensured.
The insulating threshold is arranged at the connecting part of the aluminum alloy threshold and the bottom supporting component, namely between the aluminum alloy threshold and the bottom supporting component. The strength and the insulating property of the insulating threshold can be ensured, so that the insulation between the insulating threshold and the bottom supporting structural member of the platform door can be realized under the condition that the structural strength of the threshold is not influenced, and the ground insulation is realized. At all contact sites, the insulating distance of no less than 5mm is achieved, insulation can be effectively guaranteed, and meanwhile repair and cleaning are facilitated.
Further, according to the invention, at the hole of the metal threshold body for the upright post to pass through, the insulating threshold has a baffle plate extending upwards for insulating the upright post and the metal threshold body. The insulating threshold is provided with a baffle plate at the contact end with the upright post, the baffle plate is higher than the metal threshold body, and the metal threshold body and the upright post are electrically isolated to prevent the metal threshold body and the upright post from being conducted to damage insulation.

The composite insulation threshold of the invention can be arranged on a track side threshold and a station side threshold.
The composite insulation threshold is convenient to replace, if the insulation material fails or the metal threshold body is partially damaged, the composite insulation threshold can be replaced independently, and the maintenance cost in use is greatly reduced.
When the doorsill is installed, the insulating doorsill is installed at the bottom of the metal doorsill and fixed through screws, then the connecting bolt of the bottom supporting component penetrates through the T-shaped groove at the bottom of the insulating doorsill to be connected with the bottom supporting component, and the metal doorsill and the bottom supporting component are isolated from each other to play an insulating role.
