Molding and positioning process for assembled taper annular concrete pole connecting member

Abstract

The invention discloses a molding and positioning process for an assembled taper annular concrete pole connecting member. The process comprises the following steps of (1) binding and molding of a polereinforcement framework,and (2) measuring and calibration of the perpendicularity of a connecting plane of the connecting member and the center axis of the reinforcement framework, and welding molding. The molding and positioning procedures are simplified to the utmost extent, and the calibration difficulty is lowered; the assembling process of the connecting member is regulated and guided, starting from the operation method and the calibration process, the simple and feasible process method is adopted, the molding and positioning technological process is standardized, and the purposes that it is guaranteed that the perpendicularity of each pole connecting member meets the quality requirements and it is guaranteed thatthe quality of an assembled taper annular pole is acceptable are achieved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a forming and positioning process for an assembled-type tipping annular concrete pole connecting member. Background technique [0002] Ring-shaped concrete poles are widely used as load-bearing components for overhead transmission lines and overhead telecommunication lines, as well as load-bearing components for lighting pillars and signal pile projects. , the product is usually formed by a centrifugal process. The maximum single forming length in China at one time is 15m. The requirements for product length are also constantly increasing. At present, the maximum height of domestic circular concrete poles has reached 36m. Usually, different methods such as flange bolt connection or steel plate ring welding are used to connect several sections of circular concrete poles with different lengths. Concrete pole products assembled into poles of different lengths greater than 15m ...

AI Technical Summary

Problems solved by technology

[0003] The ring-shaped concrete pole is made of high-quality steel bars, high-strength concrete and other materials, and adopts the composite material load-carrying member of the centrifugal forming process. Prestressed reinforced circular concrete poles, regardless of the structure of the circular concrete poles, (hereinafter referred to as assembled ring-shaped poles), what connection method is used, and the combination is connected into an assembled assembly of any length. Electric poles must comply with the national standard "Ring-shaped Concrete Pole GB / T4623-2015". However, in the actual production process, the bending degree of the assembled ring-shaped poles often exceeds the standard.
