Fireproof steel pipe concrete column structure capable of spraying
The invention provides a steel pipe concrete column structure capable of preventing fire through spraying, and belongs to the technical field of constructional engineering. The concrete-filled steel tube column structure comprises an outer steel tube and an inner steel tube, the outer steel tube is sleeved outside the inner steel tube, the peripheral surface of the inner steel tube is fixedly connected with the section of the outer steel tube through stiffening ribs, the inner steel tube is filled with concrete, the space between the inner steel tube and the outer steel tube is filled with circulating water, and exhaust holes are respectively formed in the outer steel tube and the inner steel tube corresponding to each floor position. A fire-fighting sprayer is mounted at the outer end of the exhaust hole in the outer steel pipe. According to the concrete-filled steel tube column structure, the gap between the inner steel tube and the outer steel tube is filled with circulating water, part of heat can be taken away through circulation, rising of the column body temperature is delayed, the circulating water can be used as spraying water of a fire sprinkler, the concrete-filled steel tube column has high fire resistance, fireproof materials are avoided, and the service life is prolonged. And the concrete filled steel tubular column is safer, more reliable, economical and environment-friendly in actual use.
本发明提供了一种可喷淋防火的钢管混凝土柱结构，属于建筑工程技术领域。该钢管混凝土柱结构包括：外钢管和内钢管，外钢管套于内钢管外部，且内钢管的外周面与外钢管的断面间通过加劲肋固定连接，内钢管内填充有混凝土，内钢管和外钢管间填充有循环水，外钢管及内钢管对应各楼层位置分别开设有排气孔，外钢管上的排气孔的外端安装有消防喷头。该钢管混凝土柱结构通过在内钢管和外钢管的间隙内填充循环水，可通过循环带走部分热量，延缓柱身温度的升高，且可作为消防喷头喷淋用水使用，使钢管混凝土柱具有较高耐火性能，避免使用防火材料，使得钢管混凝土柱在实际使用中更加安全可靠、经济环保。
