Scope

Scope: This document specifies the components, performance indicators, construction requirements, acceptance of the elevator shaft template device (hereinafter referred to as the elevator shaft device), maintenance, and transportation, etc. This document is applicable to the fabrication and construction of the elevator shaft device; Main technical contents: 1. Definitions are given for six terms, including overall climbing formwork, climbing system, working load-bearing beams, columns, claw arms, and positioning boxes. 2. The components of the elevator shaft device are specified, which consist of a climbing system and a shaft template. 3. Performance and indicator requirements of the elevator shaft device are stipulated. If the climbing speed of the climbing system is too slow, it will affect the climbing efficiency; if it is too fast, it will pose a safety hazard. Therefore, the climbing speed of the climbing system is regulated. While ensuring convenient construction, in order to guarantee construction safety and reasonable site layout, restrictions are placed on the loads piled on the platform, especially the location and storage form of the piled materials. It should be avoided as much as possible to pile materials in positions unfavorable to the structure's load-bearing, and instead, they should be evenly distributed in positions favorable to the platform's load-bearing. For welding processes, all welding wires used should comply with relevant standards; for standard parts, their selection should comply with the provisions of current national standards. All parts should be designed in accordance with corresponding design specifications. The materials of the shaft template should have high strength, rigidity, good corrosion resistance, moldability, weldability, machinability, and good oxidation effects. Therefore, the aluminum alloy extrusion profiles used should preferably comply with AL6061-T6 in the current national standard "Extrusion Profiles for General In
