High-strength fire-resistant exhaust passage
The invention discloses a high-strength fireproof exhaust passage. At least part of the pipe wall of the high-strength fire-resistant exhaust passage is provided with a sandwich heat insulation layer located in the middle, surface protection layers attached to the inner side and the outer side of the sandwich heat insulation layer and reinforcing layers attached between the sandwich heat insulation layer and the surface protection layers. The sandwich heat insulation layer is made of light fireproof mortar containing a non-combustible light aggregate mixture, the surface protection layer is made of anti-crack mortar containing quartz sand and silica fume, and the volume weight of the sandwich heat insulation layer is set to be half or below the volume weight of the surface protection layer. The fireproof door has the advantages of being high in strength, good in fireproof performance and low in weight.
本发明公开了一种高强耐火排气道。其中，高强耐火排气道的至少部分管壁具有位于中部的夹芯隔热层、附接在夹芯隔热层内外两侧的表面防护层以及附接在夹芯隔热层和表面防护层之间的增强层；夹芯隔热层采用含有不燃性的轻质骨料混合物的轻质防火砂浆制成，表面防护层采用含有石英砂和硅灰的抗裂砂浆制成，其中，夹芯隔热层的容重设置为在表面防护层容重的一半及以下。本发明具有强度高、防火性能好以及重量低的优点。
