Abstract

The invention relates to a fireproof rolling door capable of blocking high heat, comprising a plurality of blocking piece units adjacent to each other in series; each of the blocking piece units has a metal skeleton and a fire blocking body, and the metal skeleton has an extension bearing unit. The fire barrier is disposed on the metal skeleton and has a thermal expansion material that contacts the extension bearing.

Description

Fireproof roll door that can block high heat

The invention relates to a fireproof rolling door capable of blocking high heat, in particular to a fireproof rolling door which can be designed to improve the safety of the place, is easy to implement, and has a high cost of aluminum metal skeleton.

It is well known that the main purpose of fire testing is to simulate changes in the temperature of the escape door or gate when a fire occurs in a residential building or business premises. Generally speaking, the temperature of the fire is above 800 °C, so China's national standard CNS11127 stipulates that the one-hour fire test uses 925 ° C (heating curve) as the standard for escape door fire test. The traditional monolithic door is easier to achieve because it can be effectively achieved by coating a high thermal resistance material on the high temperature side of the monolithic door. However, in the case of a multi-piece fireproof roll door, since each of the fire shutter doors has a metal frame and the metal frame is an excellent heat conductor, when the temperature of the high temperature side of each fireproof roll door rises to During the 925 degree process, it will continue to transfer heat to the other side, so it is difficult to pass this test. In view of this, it is necessary to develop a technique that can solve the above disadvantages.

The object of the present invention is to provide a fireproof roll door which can block high heat, and the design of the first melt-breaking barrier can improve the safety of the place by the test, is easy to implement, and has low cost of the aluminum metal skeleton. In particular, the problem to be solved by the present invention is that in the case of a conventional multi-piece fireproof roll door, since each of the fire shutter doors has a metal frame and the metal frame is an excellent heat conductor, When the temperature of the high temperature side of each fire shutter is raised to 925 degrees, heat is continuously transferred to the other side, so it is difficult to pass such a test. The technical means for solving the above problems is to provide a fireproof roll door capable of blocking high heat, comprising a plurality of block units adjacent to each other in series; each of the block units has: a metal skeleton having an upper end hook portion a central frame portion, a lower end receiving portion and at least one extension receiving portion; the central frame portion is coupled to the upper end hook portion and the lower end receiving portion; the lower end receiving portion has a chamber frame segment and a lower curved hook portion; The chamber frame segment is configured to receive the upper end hook portion and is relatively movable, and the lower curved hook portion is used for hooking with the upper end hook portion; the at least one extension bearing portion is outwardly bent by the lower curved hook portion Extending integrally; a fire barrier body is disposed between the upper end hook portion, the center frame portion and the lower end receiving portion, the fireproof barrier system has a thermal expansion material contacting the extension bearing portion; thereby When the temperature of the side of the fireproof roll door rises to at least 900 degrees Celsius, the epitaxial bearing portion is heated up due to heat transfer, and when the temperature rises above the melting point of the metal of the epitaxial bearing portion, the epitaxial bearing portion is partially melted. Forming a temporary gap Meanwhile the temporary void adjacent the at least one heat-based expandable material expands due to high fever, and further temporarily fill the gap, but can block heat transmitted to the roll-up door on the other side of the fire. The above objects and advantages of the present invention will be readily understood from the following detailed description of the preferred embodiments illustrated herein.

Regarding the portion of the upper end hook portion 11 that moves relative to the lower end receiving portion 13, referring to FIG. 4, when the fire shutter door is raised, the upper side deflecting portion 112 moves out of the chamber frame segment 131, and the upper curved hook portion 111 The lower hook portion 131 is hooked to each other, and the plurality of flap units that are adjacent to each other in series are actuated. On the contrary, when the fire shutter is lowered, the upper side segment 112 is moved into the chamber frame segment 131, and the upper curved hook portion 111 and the lower curved hook portion 131 are separated from each other (as shown in FIG. 5A). The central frame portion 12 can further have: at least one first reinforcing connecting member 121 extending outward from the central frame portion 12 for connecting with the fire blocking body 20 to improve the connection of the fire blocking body 20 to The structural strength of the metal skeleton 10. At least one second reinforcing connector 122 (as shown in FIG. 9 , a first variation of the metal skeleton) extends outwardly from the central frame portion 12 and is interposed between the upper end portion 11 and the first portion Between the reinforcing connectors 121, the at least one second reinforcing connector 122 is coupled to the fire barrier 20 to improve the structural strength of the fire barrier 20 to be coupled to the metal skeleton 10. The chamber frame section 132 has a pair of end edges 13A, one of which is located at the intersection of the chamber frame section 132 and the lower curved section 131.
