The invention relates to the technical field of building structures, in particular to an assembled fireproof steel structure which comprises an upper steel beam, steel columns are fixedly connected to the two ends of the upper steel beam, a lower steel beam is fixedly connected to the two steel columns jointly, and the lower steel beam is located below the upper steel beam. The two steel columns, the upper steel beam and the lower steel beam jointly form an elevator shaft entrance used for entering an elevator shaft, the fireproof device is arranged in the elevator shaft entrance, and when a fire disaster occurs, the fireproof device automatically prevents the fire from penetrating through the elevator shaft entrance to enter the elevator shaft. Through the fireproof device, when a fire disaster occurs, the fireproof device is affected by the temperature of a fire scene to be heated, and when the temperature sensed by the fireproof device reaches the preset triggering temperature, the fireproof device is automatically triggered to block the entrance of the elevator shaft, so that the fire behavior is prevented from penetrating through the entrance of the elevator shaft to enter the elevator shaft; and the chimney effect caused by fire spreading into the elevator shaft is avoided.

    本发明涉及建筑结构技术领域,具体为一种组装式防火钢结构,包括上钢梁,所述上钢梁两端均固定连接有钢柱,两个所述钢柱上共同固定连接有下钢梁,且下钢梁位于上钢梁下方,两个所述钢柱与上钢梁以及下钢梁共同形成用于进入电梯井的电梯井入口,还包括防火装置,所述电梯井入口内设置有防火装置,当发生火灾时,防火装置自动阻挡火势穿过电梯井入口进入电梯井内。本发明通过防火装置,当发生火灾时,防火装置受到火场的温度影响而升温,当防火装置感应到的温度达到预设的触发温度时,防火装置自动触发,阻挡住电梯井入口,进而阻挡火势穿过电梯井入口进入电梯井内,避免由于火势蔓延到电梯井内而导致烟囱效应。
