Problems solved by technology

Cast iron sills have high strength, good wear resistance, and strong pressure bearing capacity, but are prone to rust and are not beautiful, and are generally only used on freight elevators; while aluminum alloy sills are beautiful in appearance and rust-free, but weak in strength and easy to wear, And the cost is high, so it is usually used on passenger elevators

Abstract

The invention relates to a compound elevator sill and the manufacturing method, and the product comprises a basal body and the protecting layer plate wrapped outside the basal body. The basal body is made of concrete or armoured concrete, the protecting plate wrapped the basal body is provided with at least the upper plate made of stainless steel. The manufacturing method is that the moulding groove shaped protecting layer plate is inversely positioned on the shaking rack, the concrete is poured into the groove cavity, then the shaking machine is started to make the concrete in the groove cavity shaking firm and flat, at last, the product is formed by static positioning natural maintenance or steam maintenance. The product of the invention has the advantages of beautiful appearance without rusting, strong wearlessness, and high integrated intensity which is of pressure-resisting. The basal body is the cheap armoured concrete with low production cost, thereby satisfying the comprehensive requirement for the passenger, goods ladder. The compound elevator sill has simple and proper manufacturing method, and the quality of the shaped product is stable and reliable.

Description

technical field [0001] The invention relates to a sill of an elevator car door or a landing door of an elevator shaft, in particular to a composite sill made of different materials and a production method thereof. Background technique [0002] The car door in the existing elevator installation or the sill of the hoistway landing door are mostly made of cast iron or aluminum alloy single material. Cast iron sills have high strength, good wear resistance, and strong pressure bearing capacity, but are prone to rust and are not beautiful, and are generally only used on freight elevators; while aluminum alloy sills are beautiful in appearance and rust-free, but weak in strength and easy to wear, And the cost is high, so it is usually used on passenger elevators. Contents of the invention [0003] The purpose of the present invention is to provide a composite elevator sill with high strength, good wear resistance, beautiful surface, no rust, low production cost and suitable for...
