Abstract

The invention discloses a reinforced counterweight for an elevator. The counterweight is prepared from raw materials in parts by weight as follows: 11-12 parts of metal fibers, 30-45 parts of ores, 22-34 parts of metal slag, 26-39 parts of cement in the water-cement ratio being 0.3-0.5 and 2-15 parts of albite, wherein the metal fibers are high-strength steel short filaments and have the length ranging from 5 mm to 30 mm. The metal fibers and the slag are recovered, a lot of resources are saved, meanwhile, the steel consumption is reduced by replacing an outer-layer iron casing and internal reinforcing steel bars of a traditional counterweight with the metal fibers, the procedure for painting the outer-layer iron casing is omitted, and the pollution to the working environment is reduced.

Description

technical field [0001] The invention relates to a counterweight, in particular to a reinforced counterweight for an elevator. Background technique [0002] At present, the counterweights on the market are mainly cast iron or cement composite counterweights, which have the disadvantages of large waste of resources, complicated processing technology, and high cost. Contents of the invention [0003] In order to solve the above problems, the present invention provides a composite counterweight with simple processing technology, minimal waste of resources and high strength. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: [0005] The invention relates to a reinforced counterweight for an elevator, and the counterweight includes the following raw materials in parts by weight: 11-12 parts of metal fiber, 30-45 parts of ore, 22-34 parts of metal slag, and 26-39 parts of cement , the water-cement ratio i...
