High-temperature heat insulation support

The utility model discloses a high-temperature heat insulation support which comprises a bottom plate, a supporting rib plate, a vacuum tube support, a hoop and a polytetrafluoroethylene assembly. The polytetrafluoroethylene assembly is fixedly connected to the top of the structural beam, and the polytetrafluoroethylene assembly, the bottom plate, the supporting rib plate, the vacuum tube support and the hoop are fixedly connected in sequence. By arranging the vacuumized closed space, heat transfer to the bottom plate can be greatly reduced; the holes are evenly distributed in the supporting rib plates, so that the heat dissipation area can be effectively increased, and the temperature of the bottom face of the bottom plate is 200 DEG C or below. The device is simple in manufacturing structure and convenient to install, maintain and replace. 本实用新型公开了一种高温隔热支架，包括包括底板、支撑筋板、真空管托、卡箍和聚四氟乙烯组合件；聚四氟乙烯组合件固定连接于结构梁顶部，聚四氟乙烯组合件、底板、支撑筋板、真空管托、卡箍依次固定连接。通过设置抽真空的封闭空间，可大大减小热量向底板传递；支撑筋板均布开孔可有效增加散热面积，使底板底面温度在200℃以下。本实用新型的制造结构简单，方便
