The invention discloses a kind of subway high intensity to shake hanger of reducing expenditure, and is related to suspension and support technical field.The subway high intensity shakes hanger of reducing expenditure and includes pipe collar, telescopic rod, adjusts screens slot and adjust the components such as screens block, and the surface of pipe collar is coated with fireprotection layer, and the chemical composition and parts by weight meter of fireprotection layer are as follows：Epoxy resin：20 30 parts, aromatic solvent naphtha：16 24 parts, dipentaerythritol：5 10 parts, toluenesulfonic acid：15 30 parts, polyethylene glycol：6 30 parts, polyurethane：25 parts, alumina silicate：13 parts, aluminium hydroxide：14 parts, filler：25 parts, auxiliary agent：26 parts.By adjusting limiting slot and adjusting being used cooperatively for limited block, so that pipe collar can adjust angle, it can keep firm again, fireprotection layer meets the rapid expansion of fire simultaneously, it is wrapped in the surface of pipe collar, so that effectively flame be isolated with pipe collar, epoxy resin and alumina silicate also effectively increase the corrosion resistance of fireprotection layer so that suspension and support disclosure satisfy that fire prevention and the requirement of corrosion resistance. |
