Problems solved by technology

[0003] However, the further popularization and application of prefabricated concrete structures is facing bottlenecks
Compared with cast-in-place structures, prefabricated concrete structures have higher quality requirements for construction technology, especially vertical components represented by columns and shear walls are important force-bearing components in prefabricated concrete structures. The key points and difficulties in construction, but the current professional quality of construction personnel is not high overall, lack of accumulation and summary of technical experience in prefabricated concrete structures, and lack of comprehensive and accurate understanding and mastery of the process flow and key points of operation of prefabricated structures, resulting in Low construction efficiency, large construction errors, and even construction errors

Abstract

The invention provides a method for rapid positioning and mounting construction of fabricated structure concrete vertical components, and relates to a positioning and mounting construction method. Themethod comprises the technological steps of construction preparation, site acceptance, acceptance and treatment of an original structure, surveying and setting-out, hoisting, mounting in place, grouting filling, maintenance, demolition, self-inspection and marking, and acceptance, a customized limiting formwork is utilized, steel bar precise positioning, and prefabricated wall plate and column component alignment mounting measures are adopted, an elevation, horizontal position and verticality fine-tuning correction methods are summarized, and part of measurement means in steel structure construction are introduced creatively, so that component fine-tuning in place is faster and more precise, a complete set of positioning and mounting construction technology is formed, the problem of precise positioning and mounting of the vertical components is solved, and the construction quality is ensured more easily.

Description

technical field [0001] The invention relates to the field of positioning and installation construction methods, in particular to a rapid positioning and installation construction method for a concrete vertical component of a prefabricated structure. Background technique [0002] Prefabricated concrete structure is an inevitable demand for the development of modern industrialization of my country's construction industry. Due to its low pollution, high degree of industrialization, energy saving and environmental protection, and its suitability for my country's increasingly tense labor resources, it has been vigorously promoted in recent years. [0003] However, the further popularization and application of prefabricated concrete structures is facing a bottleneck. Compared with cast-in-place structures, prefabricated concrete structures have higher quality requirements for construction technology, especially vertical components represented by columns and shear walls are import...
