Synchronous pouring construction method of preset isolation layer for concrete structural column

Abstract

The invention relates to a construction method for synchronous pouring of a preset isolation layer of a concrete structural column. The main construction steps include: (1) construction preparation; (2) processing of structural column longitudinal bars and stirrups; Erecting; (4) Construction of the main reinforcement of the structural column; (5) Construction of the structural column stirrup; (6) Erection of the structural column formwork support, reserving the structural column pilot hole; (7) Concrete pouring below the pilot hole; (8) Isolation layer Formwork installation; (9) laying out waste receiving trough; (10) installing sand filling device; (11) pouring isolation sand; (12) leveling and feeding with feeding device; (13) closing pilot hole; ( 14) Pouring concrete above the pilot tunnel; (15) Dismantling the formwork to treat the sand layer. The construction method of synchronous pouring of the preset isolation layer of the concrete structural column adopted by the invention has the advantages of convenient construction, convenient assembly and disassembly of the formwork, recyclable formwork, sustainable utilization of resources, and good economic and technical benefits.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a construction method for synchronous pouring of a preset isolation layer of a concrete structural column, which is suitable for the synchronous pouring construction of a preset isolation layer of a concrete structural column. Background technique [0002] With the development of economy and society, the facade shapes of buildings are also becoming more and more abundant. More and more building facades use modeling columns and structural walls. At the same time, one end of the outer structural walls of many buildings is a free end, which must also be Add structural columns. Seismic structural columns play an important role in strengthening the overall mechanical performance of the frame structure and filling walls, and protecting the lives and property of the people and national property.

Problems solved by technology

[0003] If the secondary pouring is done after the completion of the main body construction, due to the inconvenient vibration during this process, it is easy to produce poor honeycomb pockmarking quality. At the same time, it needs cumbersome planting bars, steel cage binding, formwork support, concrete pouring, demolition A series of processes such as molds are time-consuming and labor-intensive. At the same time, a large amount of construction waste is generated, and the quality is not easy to control.

The most important thing is that it is very easy to cause safety accidents and seriously delay the construction period

[0004] However, the traditional construction method is that the steel skeleton of the structural column is not constructed synchronously with the main structural beam, which cannot ensure the seismic performance, engineering quality and construction safety of the structural column; The quality of the connection with the frame beam is a common problem; moreover, there are many lap joints of the longitudinal reinforcement of the structural column, which wastes the reinforcement
