Fire-retardant strip for narrower building gap
The invention discloses a fire-retardant strip for a narrower building gap. The fire-retardant strip for the narrower building gap is characterized in that the fire-retardant strip is a flexible cylindrical strip-shaped body, a cylindrical spiral spring core body (1) is arranged in the center of the fire-retardant strip, a high-temperature-resistant heat insulation cotton layer (2) is wrapped on the peripheral surface of the cylindrical spiral spring core body (1), and a high-temperature-resistant fiber layer (3) is wrapped outside the high-temperature-resistant heat insulation cotton layer (2). According to the fire-retardant strip for the narrower building gap, the fire-retardant strip for the narrower building gap is completely flexible, can cope with irregular gaps, and is simple and convenient to construct.
一种较窄建筑缝隙用阻火条，其特征在于：该阻火条为一柔性的圆柱形条状体，它中心为一圆柱螺旋弹簧芯体（1），在圆柱螺旋弹簧芯体（1）的外周面上包覆耐高温绝热棉层（2），在耐高温绝热棉层（2）的外部包覆有一耐高温纤维层（3）。本发明完全是柔性的，能应对不规则的缝隙，施工简单、便利。
