Description
Technical field
The utility model is related to the built-in technical fields of rail vehicle, and in particular to a kind of city railway vehicle Novel fireproof lattice
Grid.
Background technology
Status of the fire safety demands in each city railway vehicle project is more and more important, is carrying out partition design process
In, need the sealing fire prevention processing for considering ventilation opening.Currently, in order to meet a wall components fire protection requirement, between guest room end
At wall and drivers' cab partition ventilation opening, generally using finished product fire prevention cell structure is inlayed, although this structure can meet BS6853
Fire protection requirements in 30 minutes of fire prevention and ISO834 standards in 20 minutes of standard, but this finished product fire prevention grid is external standard
Part, width dimensions must be 5 integral multiples, and only there are four types of specifications for thickness, cannot fully meet domestic city railway vehicle to ventilation opening
Size requirement；Meanwhile this finished product fire prevention grid is from external import, procurement cycle is long, and cost is higher.
Utility model content
Domestic city railway vehicle cannot be fully met to ventilation in order to solve dimensions existing for existing finished product fire prevention grid
Mouthful size require and this finished product prevents fires grid from external procurement cycle is long, the higher technical problem of cost, the utility model
A kind of city railway vehicle Novel fireproof grid is provided.
The utility model technical solution adopted for solving the technical problem is as follows：
City railway vehicle Novel fireproof grid comprising steel frame and multiple fire prevention expand adhesive tape；Steel frame passes through fire prevention
Expansion glue is pasted onto on the ventilation opening component of city railway vehicle, and the outline border of steel frame is rectangular configuration, and the inside of rectangular configuration is etc.
Spaced multiple lateral steel bars and a vertical steel bar being arranged in rectangular configuration midline position, lateral steel bar and vertical steel
The both ends of item with above-mentioned outline border be connected, it is two neighboring transverse direction steel bar between be divided into 20mm；Multiple fire prevention expand adhesive tape one
One corresponds to the upper surface for being pasted onto multiple lateral steel bars, and the thickness of each fire prevention expansion adhesive tape is 4mm.
The utility model has the beneficial effects that：The steel frame of the Novel fireproof grid can ensure that overall stiffness, fire prevention are swollen
Swollen adhesive tape and fire prevention expansion glue play the role of expanded by heating barrier gap.The Novel fireproof cell structure is simple and practical, manufacture
Cost is only the one third of former finished product.By existing vehicle using testing, the sealing of partition ventilation opening ventilating fire prevention has been fully met
Requirement.

Specific implementation mode
The utility model is described in further details with reference to the accompanying drawings and examples.
As shown in Figures 1 to 6, the city railway vehicle Novel fireproof grid of the utility model includes steel frame 1 and multiple anti-
Fire expansion adhesive tape 2；Steel frame 1 is pasted onto by expansion glue 3 of preventing fires on the ventilation opening component 4 of city railway vehicle, the outline border of steel frame 1
1-1 is rectangular configuration, and the inside of rectangular configuration is that the multiple transverse direction steel bar 1-2 being arranged at equal intervals and one are arranged in rectangular configuration
The both ends of the vertical steel bar 1-3 of midline position, lateral steel bar 1-2 and vertical steel bar 1-3 are connected with above-mentioned outline border 1-1, adjacent
It is divided into 20mm between two lateral steel bar 1-2；Multiple fire prevention expansion one-to-one correspondence of adhesive tape 2 are pasted onto multiple lateral steel bar 1-
The thickness of 2 upper surface, each fire prevention expansion adhesive tape 2 is 4mm.Fire prevention expansion adhesive tape 2 can select LORIENT companies to provide
The fireproofing glue strip of LP2004 models, fire prevention expansion glue 3 can select happiness is sharp to obtain (HILTI) CP 611A expansion fire-proof fluid sealants.
In no fire, the fire prevention grid of the utility model can normally divulge information；When there is fire, fire prevention expansion
Adhesive tape 2 and fire prevention expansion glue 3 meet fiery expansion, the gap and steel frame 1 between the two neighboring lateral steel bar 1-2 of closure and ventilation
Gap between mouth component 4, obstructs flame, is finally reached the purpose of ventilating fire prevention.
