Passive-type low-energy-consumption steel composite fireproof door

Abstract

The invention discloses a passive-type low-energy-consumption steel composite fireproof door. The door comprises a door frame (1) and a door leaf (2), a fireproof door lock (3) is arranged on the doorleaf (2), and the door leaf (2) is connected with the door frame (1) through a hinge (4); the door is characterized in that a bridge cutoff structure is arranged on the step-shaped matching face of the door frame (1) and the door leaf (2), a blocking seal strip (5) is arranged on the step-shaped matching face of the door leaf (2), the door leaf (2) is composed of a fireproof heat preservation plate and a wrapping steel plate, the door frame (1) is composed of a base material (6), a high-temperature-resistant layer (7) and a wrapping steel plate, and the high-temperature-resistant layer (7) covers the indoor surface of the base material (6) and the contact surface of the base material (6) and a building. The passive-type low-energy-consumption steel composite fireproof door has comprehensive overall performance of excellent heat preservation performance, safety anti-theft performance and high-temperature-resistant waterproof performance.

Description

Technical field: [0001] The invention relates to an entrance door used in a building, in particular to a fireproof door of steel composite material with low energy consumption. Background technique: [0002] The entrance door is an essential component of a building, and it is also the first safety barrier for residents. With the high-rise building, the requirements for the safety and fire performance of the entrance door are getting higher and higher, and at the same time, it is environmentally friendly. The requirements for energy saving are also increasing, so the cost of preparing entrance doors that meet national standards is also increasing, and there are many technical means adopted, but the existing technology mainly solves the problem on a single index. There is a restrictive effect between them, and highlighting a certain technical performance may damage another technical performance. Therefore, there is no comprehensive performance of the entrance door, but it is s...

[0002] The entrance door is an indispensable component of the building, and it is also the first safety barrier for the residents. With the high-rise building, the requirements for the safety and fire performance of the entrance door are getting higher and higher, and at the same time, it is environmentally friendly. The requirements for energy saving are also increasing, so the cost of preparing entrance doors that meet national standards is also increasing, and there are many technical means adopted, but the existing technology mainly solves the problem on a single index. There is a restrictive effect between them, highlighting a certain technical performance may damage another technical performance, so there is no comprehensive performance of the entrance door, but it is still a problem that needs to be solved urgently
