Problems solved by technology

[0002] Fire door refers to the door body that can meet the fire resistance stability, integrity and heat insulation within a certain period of time. The gap between fire or smoke is usually installed with an expansion fireproof sealing strip. The current fireproof sealing strip is a strip embedded in the edge of the door leaf or door frame, which only expands to seal when a fire occurs. In most of the daily life (that is, the time when there is no fire danger) has no other functions and has a single function

Embodiment Construction

[0015] The scheme of this application is further described in conjunction with the accompanying drawings as follows:

[0016] See attached Figure 1-2 , a fireproof and anti-collision sealing strip, including a strip-shaped main body 1 made of fireproof materials, preferably, the fireproof and anticollision sealing strip is made of fireproof materials containing expanded graphite, specifically made of flexible resin and The composite material of expanded graphite is directly molded. The expanded graphite can expand more than 20 times when heated, and the composite flexible resin makes the finished product elastic.

[0017] The cross-section of the main body 1 is square, specifically the side length of the square is 5mm. The bottom side of the main body 1 extends horizontally with a wide side 2, and the side of the wide side 2 away from the main body 1 is obliquely bent and has an elastic fold 3 , the direction of inclination of the elastic hem 3 is opposite to the position of...

Abstract

The invention provides a fireproof and anti-collision sealing strip, comprising a strip-shaped main body made of a fireproof material, one side of the main body horizontally extends to form a wide edge, one side, away from the main body, of the wide edge is obliquely bent to form an elastic folded edge, the oblique direction of the elastic folded edge is opposite to the position of the main body,the included angle between the wide edge and the elastic folded edge is an acute angle, and the elastic folded edge is elastically bent; and a plurality of bulges are arranged on the left side and / orthe right side of the main body by taking the extending direction of the wide edge as the right side of the main body. According to the fireproof and anti-collision sealing strip, collision friction between door leaves and between a door leaf and a door frame can be reduced, the fireproof and anti-collision sealing strip can expand when a fire disaster occurs to seal gaps between the door leaves and between the door leaf and the door frame, fire penetration and poisonous smoke invasion of mounting gaps are prevented, and the fireproof and anti-collision effects are achieved.

Description

technical field [0001] The invention relates to a fireproof and anticollision sealing strip. Background technique [0002] Fire door refers to the door body that can meet the fire resistance stability, integrity and heat insulation within a certain period of time. The gap between fire or smoke is usually installed with an expansion fireproof sealing strip. The current fireproof sealing strip is a strip embedded in the edge of the door leaf or door frame, which only expands to seal when a fire occurs. In most of the daily life (that is, the time when there is no fire danger) has no other effects and has a single function. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a fireproof and anti-collision sealing strip, which can reduce the collision friction between the door leaf and the door leaf, and between the door leaf and the door frame, and can expand when a fire occurs at the same time. The gap is sealed to preven...
