Problems solved by technology

The outer shell and internal reinforcing steel bars of the above-mentioned synthetic counterweights are all for improving the compressive and impact resistance strength of the counterweights. The manufacturing process needs to consume more steel materials, and requires a lot of manual welding operations, and the labor cost and material cost are high. High, welding operation is not conducive to environmental protection

Abstract

The invention discloses a synthesized counterweight block for an elevator. A counterweight block body is of a blocky structure formed through mixed pouring of metal fiber, ore, metal slag, cement and a proper amount of water, wherein the counterweight block body comprises, by weight, 32-39 parts of the metal fiber, 55-63 parts of the ore, 12-23 parts of the metal slag and 9-20 parts of the cement. The metal fiber material is adopted for replacing an iron shell on the outer layer of a traditional counterweight block and strengthening steel bars in the traditional counterweight block, the usage amount of steel is reduced, the welding procedures are reduced, the painting procedure of the iron shell on the outer layer is omitted, and pollution to the work environment is reduced.

Description

technical field [0001] The invention relates to a counterweight, in particular to a synthetic counterweight for an elevator. Background technique [0002] The elevator composite counterweight currently used in the market is mainly composed of shells, reinforced steel bars, concrete and other materials mixed and poured. The outer shell and internal reinforcing steel bars of the above-mentioned synthetic counterweights are all for improving the compressive and impact resistance strength of the counterweights. The manufacturing process needs to consume more steel materials, and requires a lot of manual welding operations, and the labor cost and material cost are high. High, welding operation is not conducive to environmental protection. Contents of the invention [0003] In order to solve the above problems, the present invention provides a synthetic counterweight that greatly reduces the amount of steel used, reduces manufacturing and labor costs, improves manufacturing eff...
