Abstract

The utility model discloses a diameter-adjustable fireproof ring consisting of a long thin metal band and an elastic flame-retardant strip. Fracture lines are uniformly distributed at intervals in the length direction of the long thin metal band which is partitioned into multiple mutually consecutive small rectangular strips by the fracture lines uniformly distributed at intervals, two outer sides of each of the spaced small rectangular strips are provided with small trapezoidal vertical edges which are in the same direction and perpendicular to the corresponding small rectangular strip, and a gap bridge ring is arranged in the middle of each small rectangular strip, and the gap bridge rings are connected integrally. Using the diameter-adjustable fireproof ring can realize sealing among indoor pipelines communicated to external buildings and passageways, and gaps among the indoor pipelines communicated to the external buildings and passageways are avoided once fire accidents occur outdoors, so that smoke is prevented from invading through the indoor pipelines communicated to the external buildings and passageways, and indoor personnel is protected from gas poisoning.

Description

Adjustable bore fire stop ring

Technical field:

The utility model belongs to the Building Fire Protection device, particularly a kind of adjustable bore fire stop ring.

Background technique:

At present; Interior architecture has the pipeline that much leads to outside building body, corridor, owing to seal around these pipelines, and therefore in a single day outdoor building body, the corridor generation condition of a fire; Flue gas can be invaded indoor from packing less pipeline peripheral clearance, causes the indoor occupant smoke poisoning easily.

The model utility content

The purpose of the utility model provides a kind of adjustable bore fire stop ring.Use it can reach indoor seal for pipe joints of leading to building, outside body, corridor; Therefore in case building, indoor outside body, the corridor generation condition of a fire; There is not the slit between the pipeline of building body, corridor outside indoor leading to; Flue gas can not invaded between the pipeline of building body, corridor outside indoor leading to, and can not cause the indoor occupant smoke poisoning.

The content of the utility model is:

A kind of adjustable bore fire stop ring is characterized in that: adjustable bore fire stop ring is made up of a long band of thin metal and elastic flame bar; It is arranged with evenly spaced line of fracture on the direction of the length of the thin long zone face of metal; Be partitioned into a plurality of mutual continuous little rectangular strips by evenly spaced line of fracture on the thin long zone face of metal, have unidirectional on two outer side of little rectangular strip face separately and perpendicular to the little trapezoidal stile of little rectangular strip face; There is the bridged ring of crossing that is connected as a single entity centre on each little rectangular strip face, and the direction of little trapezoidal stile is built up in the both sides that approach the long zone face of metal respectively with the direction of crossing bridged ring; In the concave surface that the little trapezoidal stile on both sides surrounds on being with it by thin metal length the elastic flame bar is housed.

By the fire stop ring that the elastic flame bar in the long band of thin metal and its concave surface curves, the long zone face of thin metal on its fire stop ring is at the outer surface of fire stop ring, and elastic flame bar face is at the internal surface of fire stop ring; Thin metal length at the fire stop ring outer surface is inserted with the fork sheet on the metal folding pin with crossing in the bridged ring on the little rectangular strip face.

The characteristic advantage of the utility model:

Using it can reach the indoor pipeline that leads to building, outside body, corridor seals on every side; Therefore in case the condition of a fire takes place outdoors; There is not the slit between the pipeline of building body, corridor outside indoor leading to; Flue gas can not invaded between the pipeline of building body, corridor outside indoor leading to, and can not cause the indoor occupant smoke poisoning.

Embodiment

A kind of adjustable bore fire stop ring as shown in Figure 1, adjustable bore fire stop ring is with 1 to form with elastic flame bar 4 by a thin metal length; It is arranged with evenly spaced line of fracture 2 on the direction of the length of the thin long zone face of metal; Be partitioned into a plurality of mutual continuous little rectangular strips by evenly spaced line of fracture on the thin long zone face of metal, have unidirectional on two outer side of little rectangular strip face separately and perpendicular to the little trapezoidal stile of little rectangular strip face; There is the bridged ring of crossing that is connected as a single entity centre on each little rectangular strip face, and the direction of little trapezoidal stile is built up in the both sides that approach the long zone face of metal respectively with the direction of crossing bridged ring; In the concave surface that the little trapezoidal stile on both sides surrounds on being with it by thin metal length the elastic flame bar is housed.

By the fire stop ring that the elastic flame bar in the long band of thin metal and its concave surface curves, the long zone face of thin metal on its fire stop ring is at the outer surface of fire stop ring, and elastic flame bar face is at the internal surface of fire stop ring; Thin metal length at the fire stop ring outer surface is inserted with the fork sheet on the metal folding pin 3 with crossing in the bridged ring on the little rectangular strip face.

During use; Adopt line of fracture will approach the length that the long band of metal and elastic flame bar cut the surperficial girth in the PVC plastic tube outer ring that is suitable for passing body of wall or floor; Again the line of fracture that cut will be approached the long band of metal encloses circlewise with the elastic flame bar is curved; This ring set in PVC plastic tube 5 outsides of passing body of wall or floor, is inserted thin metal length to the fork sheet on the metal folding pin 3 with crossing in the bridged ring on the little rectangular strip face again, again the metal folding pin is screwed on the metope of building.

Using it can reach the indoor pipeline that leads to building, outside body, corridor seals on every side; Therefore in case the condition of a fire takes place outdoors; The indoor pipeline that leads to building, outside body, corridor does not have the slit on every side; The pipeline of building body, corridor was not invaded on every side outside flue gas can indoorly not lead to, and can not cause the indoor occupant smoke poisoning.Owing to pad is processed by fire-retardant thermal expansion material, fire can not burn in advance, expands on the contrary to make the indoor pipeline that leads to building, outside body, corridor seal tightr on every side.

Claims

1. adjustable bore fire stop ring is characterized in that: adjustable bore fire stop ring is made up of a long band of thin metal and elastic flame bar; It is arranged with evenly spaced line of fracture on the direction of the length of the thin long zone face of metal; Be partitioned into a plurality of mutual continuous little rectangular strips by evenly spaced line of fracture on the thin long zone face of metal, have unidirectional on two outer side of little rectangular strip face separately and perpendicular to the little trapezoidal stile of little rectangular strip face; There is the bridged ring of crossing that is connected as a single entity centre on each little rectangular strip face, and the direction of little trapezoidal stile is built up in the both sides that approach the long zone face of metal respectively with the direction of crossing bridged ring; In the concave surface that the little trapezoidal stile on both sides surrounds on being with it by thin metal length the elastic flame bar is housed.
