Thin-wall hollow pier pouring connecting structure and construction method thereof

Abstract

The invention discloses a thin-wall hollow pier pouring connecting structure and a construction method thereof. The connecting structure comprises pier reinforcing steel bars connected in sections, alower frame body connected to the lower portions of the pier reinforcing steel bars, an upper frame body connected to the upper portions of the pier reinforcing steel bars, a set of formwork connectedto the middles of the pier reinforcing steel bars, and a template connected to the outer sides of the reinforcing steel bars bound with the reinforcing steel bars. The template comprises an inner template and an outer template, and the outer side of the outer template is connected with a platform plate and a fence. Through the arrangement of the upper frame body, the lower frame body and the positioning holes used for positioning the pier reinforcing steel bars in the upper frame body and the lower frame body, the pier reinforcing steel bars can be preliminarily laterally limited under the large frame; through the arrangement of the formwork, pier steel bars can be accurately positioned, and the formwork can also be used as a construction platform, so that the operation of constructors isfacilitated; by means of off-site binding and positioning of segmented pier steel bars, staged construction is facilitated, construction efficiency is improved, and construction accuracy is improved.Through the arrangement of the platform plate and the connecting component, safe and convenient construction of constructors is facilitated.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a thin-walled hollow pier pouring connection structure and a construction method thereof. Background technique [0002] In recent years, the pouring and turning construction method of tall and thin-walled hollow piers has been widely used in the construction of expressways. The requirements for the spacing of steel bars and the pass rate of protective layers for thin-walled hollow piers have gradually become stricter. The traditional method of construction cannot meet the progress and quality requirements. . Therefore, reducing the safety risk of high-altitude thin-walled hollow pier construction, mastering the key points of construction control technology, ensuring the sensory quality of thin-walled hollow pier body concrete, improving the positioning accuracy of pier body reinforcement, the pass rate of protective layer, and improving construction efficiency and safety have...
