Abstract
A kind of shrinkage type sealing strip isolation fireproof section bar, is related to a kind of fireproof section bar.The utility model in order to solve the problems, such as existing glazing tape be naked state PVC door and window there are biggish security risks.Shrinkage type sealing strip is isolated fireproof section bar and is made of profiled body and main body hook；Profiled body is the sheet metal that section is arc, and one end of main body hook and the extrados of profiled body are affixed, the other end of main body hook be it is hook-shaped, the main body of main body hook is metal shell, is filled with plastic core material in the metal shell of main body hook.Fireproof section bar is isolated in the utility model shrinkage type sealing strip can be delayed glazing tape burning or high temperature flowering structure to destroy in door and window by fiery process, can further increase isolation flameproof effect filled with plastic core material in the metal shell of the main body hook of setting.The isolation that the utility model is suitable for glazing tape is prevented fires.
Description
Technical field
The utility model relates to a kind of fireproof section bars.
Background technique
Smog is spread in fire, anoxia asphyxia is the first cause of causing death.In western developed country, system fireproof
Theory morning is it is widely known that require flame resistant glass and frame system all to have fire-proof function, and China then deposits mistake on concept
Area often only payes attention to the fire prevention of glass itself.Door glass or door window frame become the burning gallery of fire after being ruptured by fire, and
It is spread in building interior, to form three-dimensional fire.The opening position that building external doors and windows are safeguarded as building, is structural fire protection
The essential ring of facility, the fire protecting performance of building external doors and windows have become prevent building flame interlayer spread it is crucial because
Element.
But the fire line design of existing building PVC door and window is upper there is also many flaws, in PVC door and window glass and
It is glazing tape between sash, and glazing tape is naked state, during door and window is by fire, due to glazing tape
Fire resistance can not show a candle to sash profile, therefore, glazing tape will burn first or high temperature flowering structure destruction make glass capsulation
Loss of seal performance, glazing tape position will alter cigarette at first to alter fiery position, finally will affect whole PVC
The fire resistance of door and window, thus existing glazing tape be naked state PVC door and window there are biggish security risks.
Utility model content
There are biggish security risks in order to solve the PVC door and window that existing glazing tape is naked state for the utility model
The problem of, propose a kind of shrinkage type sealing strip isolation fireproof section bar.
The utility model shrinkage type sealing strip is isolated fireproof section bar and is made of profiled body and main body hook；
The profiled body is the sheet metal that cross section is arc, and one end of main body hook and the extrados of profiled body are solid
Connect, main body hook the other end be it is hook-shaped, main body hook main body be metal shell, main body hook metal shell in be filled with
Plastic core material；
Hook-shaped one end of the main body hook is set in the glazing tape mounting groove of the press strip inside PVC door and window；
The wall thickness of the metal shell of the main body hook is 0.5~0.9mm；
The wall thickness of the metal shell of the main body hook is 0.7mm；
The plastic core material filled in the metal shell of main body hook with a thickness of 4~6mm；
The plastic core material filled in the metal shell of main body hook with a thickness of 5mm.
The utility model have it is following the utility model has the advantages that
1, the utility model shrinkage type sealing strip isolation fireproof section bar is in use, hook-shaped one end that main body is linked up with is set to
In the glazing tape mounting groove of press strip inside PVC door and window, the both ends of profiled body are closely attached on glass and press strip respectively at this time
Surface, door and window is during by fire, shrinkage type sealing strip be isolated fireproof section bar can effective isolated temperature, delay glazing tape
Burning or high temperature flowering structure are destroyed；
2, due to being filled with plastic core material in the metal shell of main body hook, the main body of main body hook is metal shell, gold
The thermal expansion coefficient of category is swollen lower than the heat of plastics, and door and window is during by fire, the plastic core of filling in the metal shell of main body hook
Material is expanded the main body that expansive force links up with main body is generated, and the volume of the main body of main body hook is fixed, and then main body is linked up with
Metal shell thickness increase, the length of metal shell of main body hook becomes smaller, and then to profiled body to glazing tape one
Side tenses, and is bonded profiled body with glass and press strip surface even closer, improves isolation flameproof effect into one.
Detailed description of the invention:
Fig. 1 is that fireproof section bar structural schematic diagram is isolated in the utility model shrinkage type sealing strip；
Fig. 2 is the sash structures schematic diagram for being equipped with the utility model shrinkage type sealing strip isolation fireproof section bar.
Specific embodiment:
The technical solution of the present invention is not limited to the following list, further includes between each specific embodiment
Any reasonable combination.
Specific embodiment 1: illustrating present embodiment in conjunction with Fig. 1~2, the isolation of present embodiment shrinkage type sealing strip is anti-
Fire type material is made of profiled body 1 and main body hook 2；
The profiled body 1 is the sheet metal that cross section is arc, one end of main body hook 2 and the outer arc of profiled body 1
Face is affixed, and the other end of main body hook 2 is hook-shaped 3, and the main body of main body hook 2 is metal shell, the metal shell of main body hook 2
It is interior to be filled with plastic core material 4；
Hook-shaped 3 one end of the main body hook 2 is set in the glazing tape mounting groove of the press strip inside PVC door and window.
Present embodiment have it is following the utility model has the advantages that
1, present embodiment shrinkage type sealing strip isolation fireproof section bar is in use, hook-shaped 3 one end of main body hook 2 is arranged
In the glazing tape mounting groove of press strip inside PVC door and window, the both ends of profiled body 1 are closely attached on glass and pressure respectively at this time
Surface, door and window is during by fire, shrinkage type sealing strip be isolated fireproof section bar can effective isolated temperature, delay glass capsulation
Item burning or high temperature flowering structure are destroyed；
2, due to being filled with plastic core material 4 in the metal shell of main body hook 2, the main body of main body hook 2 is metal shell,
The thermal expansion coefficient of metal is swollen lower than the heat of plastics, and door and window is during by fire, the plastics of filling in the metal shell of main body hook 2
Core material 4 expands the main body of main body hook 2 for expansive force is generated, and the volume of the main body of main body hook 2 is fixed, and then main body
The metal shell thickness of hook 2 increases, and the length of the metal shell of main body hook 2 becomes smaller, and then close to glass to profiled body 1
Strip of paper used for sealing side tenses, and is bonded profiled body 1 with glass and press strip surface even closer, improves isolation fire prevention effect into one
Fruit.
