Description

Half high door extending structure of track traffic platform

Technical Field

The utility model belongs to the rail transit equipment field especially relates to a half high door extending structure of rail transit platform.

Background

The rail transit platform half-height door is usually arranged at an elevated station or a ground station and used for isolating a rail traveling area, guaranteeing the safety of passengers and beautifying the waiting environment. Because the expansion joint needs to be arranged in the elevated station or the ground station to protect the main structure of the building, and the platform half-height door is just arranged on the expansion joint in a spanning way, the expansion joint needs to be arranged to adapt to the change of the expansion joint. As shown in fig. 1, in the existing scheme, a fire-retardant adhesive tape is bonded to the side of the glass of the door body in a full-length manner to shield the gap of the expansion amount, a limit screw is inserted into a door frame and connected with a steel structure upright post (integrally connected with a civil engineering foundation), and the limit screw determines the appropriate length according to the range of the deformation amount of the expansion joint. When the size of the expansion joint changes along with the change of the environmental temperature, the door body (the combination of the door frame and the glass) generates a certain slippage on the limiting screw, and the door body is protected from being damaged. The width of adhesive tape is difficult to confirm in practical application to this scheme, produces the gap easily between fire-retardant adhesive tape and steel construction stand when the expansion joint grow, and the adhesive tape can produce the fold when diminishing, influences the external light effect. The adhesive tape is bonded between the glass plates, so that the process control is unstable and the falling phenomenon is easy to generate. The limit screw needs a larger length, the connection strength is weak, and the limit screw is easy to deflect under the action of the weight of the door body.
