Description

Aluminum elevator shaft structure Technical Field The utility model relates to an elevator hoistway structure, in particular to an aluminum elevator hoistway structure. Background The shaft is a passage space for the movement of the car and the counterweight of the elevator, and the shaft wall of the shaft is mainly divided into a concrete shaft and a steel structure shaft. Steel structure shafts are often secured to concrete walls of the well and are typically assembled into a unitary structure by welding or bolting. Because the steel structure well formed by adopting the welding means has the problems of high construction difficulty, high requirement on the welding process of high-altitude operation and the like, more prefabricated steel structure wells are adopted at present. After the steel structure well in the prefabricated member structural form is uniformly processed and molded in a factory, all the parts are connected together through bolts on a construction site and fixed on a concrete well wall, so that a high-altitude welding process is omitted, and popularization and implementation are facilitated. Therefore, assembled elevator hoistway structures typified by steel materials are increasingly being widely used. In view of the fact that the aluminum alloy material has strength close to that of high alloy steel, the aluminum alloy material is superior to steel in rigidity, and has the advantages of good casting performance, plastic processing performance, corrosion resistance, light weight and the like. Aluminum alloy hoistway structures may be used in place of steel hoistway structures in certain scenarios. Four corner positions of butt joint of four stand columns and cross beam of current aluminium system assembled elevator well structure fixed connection form square well frame, and the stability of ubiquitous hookup location, reliability effect are not good, and bear, the poor problem of shock resistance, easily initiate the incident after long-time operation, the security is relatively poor.
