Novel platform shield door frame with fire resistance, heat insulation, and sound insulation functions

Abstract

The invention discloses a novel platform shield door frame with fire resistance, heat insulation, and sound insulation functions. The novel platform shield door frame with the fire resistance, heat insulation, and sound insulation functions comprises a stainless steel frame, a bridge cutoff treatment member, a fire resistance and heat insulation material, a refractory rubber, a laminated temperedglass, a stainless steel countersunk head screw, and a stainless steel bead; the stainless steel frame comprises frame bodies on the two sides of the inside and the outside a door body, and the bridgecutoff treatment member is embedded between the frame bodies on the two sides of the inside and the outside; the stainless steel frame is filled with the fire resistance and heat insulation material;the stainless steel bead is connected with the stainless steel frame by the stainless steel countersunk head screw; and the laminated tempered glass is embedded in a frame system in a shape like theChinese character 'men' formed by the stainless steel bead and the stainless steel frame, and the refractory rubber is filled between the stainless steel frame and the laminated tempered glass. According to the novel platform shield door frame with the fire resistance, heat insulation, and sound insulation functions, energy-saving requirements such as fire resistance, heat insulation, and sound insulation which are not considered in the ordinary platform shield door are solved; and when fire occurs in a train, life safety and property safety of passengers waiting in a station are ensured, andbroad application prospects are achieved.

Description

technical field [0001] The invention relates to the field of railway and urban rail transit, in particular to a novel platform screen door frame body with functions of fire resistance, heat preservation and sound insulation. Background technique [0002] my country's current regulations stipulate that ordinary platform screen doors do not consider the functions of fire protection, heat preservation and sound insulation. The screen door body is a stainless steel frame, and the door glass is 10mm thick single-layer tempered glass. The glass and the door frame are connected by silicone structural glue, and the failure temperature is about 230°C, so the integrity of the door cannot be guaranteed in the event of a fire. In addition, the frame structure of ordinary platform screen doors does not have thermal insulation and sound insulation performance, and cannot meet the requirements of building energy conservation. [0003] Due to the requirements of building fire protection a...
