Abstract
The utility model relates to a train bottom drainage pipeline's fire-resistant structure belongs to the passive fire resistive construction of a pipeline. The erection joint is fixedly connected with the upper part of the inner wall of the steel pipe, the two arc-shaped baffles are fixedly connected with the bottom of the steel pipe, a hole and a glue filling opening are formed in the middle of each baffle, and the fireproof expansion sealant is located on the inner side of the steel pipe between the erection joint and the corresponding baffle. The advantage is novel structure, the position that needs to keep the drainage and link up to the train has carried out the fire protection, can ensure good drainage or ventilation state under the normal operating, and in case when the conflagration takes place, fire prevention inflation sealed glue in the pipe wall can expand rapidly because of high temperature and separate flame and smoke poison along propagating in the pipeline in the car, and reach the effect in effective sealed drainage pipe way or ventilation hole, prevented scurring burning and the smoke poison gas of flame from spreading in the car effectively, inside fire prevention inflation sealed glue has anti mould, corrosion-resistant and salt fog resistant performance, the construction is simple, convenient and fast is dismantled in the installation.
Description
Technical Field
The utility model belongs to a passive fire resistive construction of pipeline is applied to train bottom drainage pipeline or other pipelines.
Background
With the increasing awareness of people about fire safety, products applied to trains are required to have higher fire protection levels. Meanwhile, the requirement cannot be met only by aiming at the fire prevention of the whole structure of the train, and the fire prevention protection of more detailed parts is urgent, so that the threat to the personal safety of passengers when a fire disaster happens is reduced to the maximum extent.
At present, a drainage pipeline at the bottom of a train or other pipeline vehicles are made of stainless steel materials, a good drainage or ventilation state can be ensured under normal operation, sewage is discharged, and air circulation is kept, but passive fire prevention measures are not adopted at present, passive fire prevention can not be carried out when a fire disaster occurs, and flame and smoke toxin enter the interior of a train body from a drainage pipeline at the bottom or other pipelines to cause the fire disaster in the train.
Disclosure of Invention
The utility model provides a fire-resistant structure of train bottom drainage pipeline to solve train bottom drainage pipeline or other pipelines and do not have passive fire resistive construction's problem.
The utility model adopts the technical proposal that: the installation joint is fixedly connected with the upper part of the inner wall of the steel pipe, the two arc-shaped baffles are fixedly connected with the bottom of the steel pipe, the middle of each baffle is provided with a hole and a glue filling opening, and the fireproof expansion sealant is positioned on the inner side of the steel pipe between the installation joint and the baffle;
the mounting joint is provided with an internal thread;
the set screw is in threaded connection with the side face of the mounting joint.
The utility model has the advantages of novel structure, the position that need keep the drainage and link up to the train has carried out the fire protection, can ensure good drainage or ventilation state under the normal operating, and in case the conflagration takes place, the sealed glue of fire prevention inflation in the pipe wall can expand rapidly in separation flame and the smoke poison along the pipeline propagates the car because of high temperature, and reach the effect in effective sealed drainage pipe way or ventilation hole, prevented scurrying of flame effectively and burnt and smoke poison gas and spread in the car, the sealed glue of inside fire prevention inflation has anti mould, the performance of corrosion-resistant and salt fog resistant, the construction is simple, convenient and fast is dismantled in the installation.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a bottom view of the present invention.
Detailed Description
The installation joint 1 is fixedly connected with the upper part of the inner wall of the steel pipe 4, the two arc-shaped baffles 5 are fixedly connected with the bottom of the steel pipe 4, the middle of each baffle 5 is provided with a hole 7 and a glue pouring opening 6, and the fireproof expansion sealant 3 is positioned on the inner side of the steel pipe between the installation joint 1 and the baffle 5;
the mounting joint 1 is provided with internal threads;
the set screw 2 is in threaded connection with the side surface of the mounting joint 1;
during the preparation, earlier the upper portion fixed connection of erection joint 1 and the inner wall of steel pipe 4, again two cowl 5 and steel pipe 4's bottom fixed connection, get into the occupation module in the hole of upper portion erection joint, insert on the central round hole that two cowl 5 formed, pour into fire prevention inflation sealed glue 3 from encapsulating mouth 6, later extract the occupation module, form hole 7, be used for drainage or exhaust hole, the inflation sealed glue is the rigid polyurethane material of modification, have antimycotic, corrosion-resistant and salt fog-resistant performance, baffle 5 can prevent that the fire prevention inflation sealed glue after the solidification from droing in using.
The working principle is as follows:
will the utility model discloses pass through 1 threaded connection of erection joint with drainage pipe or ventilation pipeline lower extreme outlet or vent to with holding screw 2 fixed, when treating the conflagration breaing out, sealed glue of inside fire prevention inflation meets thermal expansion, thereby reaches the effect in effective sealed drainage pipe or ventilation hole, in stretching the car with the flue gas that produces when preventing flame and conflagration burning.
Claims (3)
1. The utility model provides a train bottom drainage pipeline's fire-resistant structure which characterized in that: the erection joint is fixedly connected with the upper part of the inner wall of the steel pipe, the two arc-shaped baffles are fixedly connected with the bottom of the steel pipe, a hole and a glue filling opening are formed in the middle of each baffle, and the fireproof expansion sealant is located on the inner side of the steel pipe between the erection joint and the corresponding baffle.
