Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.
It should be noted that all expressions of "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name or different parameters, and it is understood that "first" and "second" are merely for convenience of description and should not be construed as limiting the embodiments of the present invention, and that the directions and positions of the terms, such as "up", "middle", "down", "front", "back", "left", "right", "inner", "outer", "side", etc., in the present invention are only referred to the directions and positions of the attached drawings, and therefore, the directions and positions of the terms are used for illustrating and understanding the present invention, and are not used for limiting the subsequent embodiments of the present invention.
The fireproof door easy to open after overheating is characterized by comprising a door frame 1, a main door body 2 arranged on the door frame 1 and an additional door strip 3 arranged on the main door body 2;
the main door body 2 is smaller than the space in the door frame 1, the additional door strips 3 fill the gaps between the main door body 2 and the door frame, the surfaces of the main door body 2 facing the indoor space are provided with bolts, the additional door strips 3 are provided with sockets for accommodating the bolts, and the main door body 2 and the additional door strips 3 are detachably connected with the sockets through the bolts; the main door body 2 and the additional door strip 3 are combined to seal the space in the door frame 1. When the main door body 2 and the additional door strips 3 in the door frame 1 are baked and overheated, the bolt is opened, and the main door body 2 can be conveniently opened by dismounting the additional door strips 3, so that the escape and rescue are facilitated. In order to facilitate the detachment of the additional door strips 3, an included angle between a contact surface between the main door body 2 and the additional door strips 3 and the indoor surface of the main door body 2 is an acute angle. The area of the indoor facing surface of the additional doorstrip 3 is larger than the area of the outdoor facing surface. Furthermore, a handle is arranged on the surface of the additional door strip 3 facing the indoor.
In order to reduce the extrusion in four directions, the number of the additional door strips 3 is two, the two additional door strips 3 are perpendicular to each other, and the two additional door strips 3 are arranged on the adjacent edges of the main door body 2.
Further, in order to increase reliability, the number of the additional door strips 3 is four, and the four additional door strips 3 are respectively arranged outside the four edges of the main door body 2.
The lengths of the additional door strips 3 are respectively equal to the lengths of the sides of the main door body 2 contacted by the additional door strips. In order to completely seal, a leaking stoppage block 4 is arranged at the intersection of the two additional door strips 3. In order to facilitate the detachment of the leaking stoppage block 4, the leaking stoppage block 4 is a conical block, and the area of the surface, facing the indoor, of the leaking stoppage block 4 is larger than that of the surface, facing the outdoor, of the leaking stoppage block.
In order to increase the elasticity of the plugging block 4, the plugging block 4 is of a closed hollow structure, in order to increase the heat insulation effect, liquid water is contained in the plugging block 4, the water completely occupies the space in the plugging block 4, and the top of the plugging block 4 is provided with a pressure relief hole. In order to reduce volatilization, the diameter of the pressure relief hole is less than five millimeters.
In order to increase the heat insulation effect, the main door body 2 is of a closed hollow structure, liquid water is contained in the main door body 2, a plurality of second pressure relief holes are formed in the upper portion, facing the indoor side, of the main door body 2, and the diameter of each second pressure relief hole is smaller than five millimeters in order to reduce volatilization.
In order to further reduce volatilization, the pressure relief hole and the plugging block 4 are damaged, and a plug is plugged in the second pressure relief hole. In order to facilitate the exhaust at high temperature, the main door body 2 and the plug are prevented from being made of plastic materials due to overlarge pressure.
In order to keep the surface of the pipe smooth and convenient to detach, the additional door strip 3 is made of solid metal, so that the contact surface of the additional door strip 3 and the main door body 2 and the leaking stoppage block 4 and the contact surface of the main door body 2 and the leaking stoppage block 4 and the additional door strip 3 can be kept smooth relatively completely, and subsequent detachment is facilitated. The overall weight of the fire door is also controlled as a whole, since the additional door strip 3 is of small volume relative to the main door body 2.
Handles are arranged on the indoor surfaces of the plugging blocks 4.
In order to prevent the leakage stoppage block 4 and the main door body 2 from falling off, the leakage stoppage block and the main door body are respectively connected with the additional door strips 3 through a buckling structure.
