Problems solved by technology

Existing fire doors are compact in structure, and under the action of fire, earthquake or other external forces, it is easy to cause deformation of the fire door, making it difficult to open the fire door. Once the fire door is deformed, it will seriously affect the escape and rescue in case of fire or earthquake Work

Embodiment 1

[0027] see Figure 1-7 , a suspended fireproof and shockproof door, comprising an upper steel structure support 4, a corner support 5, an inner door frame 10, an outer door frame 11 and a lower steel structure support 13; the upper steel structure support 4 is arranged on a wall 2 above, and the upper steel structure support 4 is located below the lintel 1, there is a gap between the upper steel structure support 4 and the lintel 1, and the gap is filled with buffer material to form an upper buffer layer 14, in case of fire, Under the action of an earthquake or other external forces, the upper buffer layer 14 performs preliminary buffering; the lower steel structure support 13 is fixed on the ground 3, and the lower steel structure support 13 is vertically aligned with the upper steel structure support 4. Correspondingly, the gap between the lower steel structure support member 13 and the ground 3 is filled with buffer material to form the lower buffer layer 15, and under the ...

Embodiment 2

[0031] see Figure 8 A small door leaf 8 is added to the bottom of the door leaf 6, the small door leaf 8 is installed in the small door leaf inner frame, the door leaf 6 bottom is provided with a small door leaf outer frame corresponding to the small door leaf inner frame, the four corners of the small door leaf inner frame are connected The four corners of the outer frame are connected by the second corner supports 9, so as to ensure that the inner frame of the small door leaf and the outer frame of the small door leaf can not only move within a certain range, but also rotate within a certain range, and the inner frame of the small door leaf and the small door leaf Buffer material is filled between the outer frames to form a buffer layer between the small door frames. When the outer door frame deforms to a large extent, causing the inner door frame 10 and the door leaf 6 to deform to a certain extent, the buffer layer between the small door frames performs a certain degree of...

Abstract

The invention discloses a suspended fireproof aseismic door which comprises an upper steel structure supporting member, corner supporting members, an inner door frame, an outer door frame and a lower steel structure supporting member. The upper steel structure supporting member is arranged on a wall and positioned below a lintel, the lower steel structure supporting member is fixed on the ground, the upper end of the outer door frame is fixedly connected to the upper steel structure supporting member while the lower end of the same is connected to the lower steel structure supporting member, and the outer door frame is mounted in the wall; the inner door frame is arranged in the outer door frame, four corners of the inner door frame and those of the outer door frame are connected through the corner supporting members, each corner supporting member comprises a compression barrel, a compression rod and a connection rod, each compression sleeve slidably sleeves outside the corresponding compression rod, a spring is arranged between the bottom end of each compression rod and the bottom of the corresponding compression barrel, the front end of the compression rod is connected to the connection rod through a spherical hinge, and a door leaf is arranged in the inner door frame. The suspended fireproof aseismic door is high in safety and can still be used when an earthquake occurs or a house naturally deforms.

Description

technical field [0001] The invention relates to a door, in particular to a hanging fireproof and shockproof door. Background technique [0002] With the continuous development of society, while the social wealth is increasing, the risk of fire is also increasing, and the danger of fire is also increasing. According to statistics, the average annual fire loss in my country in the 1970s was less than 250 million yuan, and the average annual fire loss in the 1980s was less than 320 million yuan. In the 1990s, especially since 1993, the direct property losses caused by fires rose to an average of more than one billion yuan per year, and more than 2,000 people died each year. Practice has proved that with the development of society and economy, the importance of fire protection work is becoming more and more prominent. In order to reduce the loss of life and property caused by fire, more and more buildings have installed fire doors. Existing fire doors are compact in structure...
