Integrated steel bar mold-free cast-in-place concrete column

Abstract

The invention discloses an integrated steel bar mold-free cast-in-place concrete column. The concrete column comprises a box type column shell, a steel bar framework and a tie part. The box type column shell is provided with a through cavity in the extending direction of the box type column shell and comprises a plurality of side panels, the side panels form the box type column shell, the steel bar framework is accommodated in the cavity of the box type column shell, the length of the steel bar framework in the extending direction is larger than the length of the box type column shell in theextending direction, the tie part is located inside the box type column shell, and the two ends of the tie part are fixed to two opposite side panels of the box type column shell respectively. When the concrete column is used, a large amount of concrete in a prefabricated concrete structure is prevented from being introduced into a prefabricated beam product of a component factory too early, and the concrete pouring procedure high in field construction efficiency is still implemented on site.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a form-free cast-in-place concrete column with integrated steel bars. Background technique [0002] In traditional cast-in-place concrete structure engineering, the on-site construction efficiency of formwork and reinforcement is very low, and the average daily output value does not exceed 2,300 yuan; the on-site construction efficiency of door and window installation, block filling wall, external insulation and painting is even lower, and the daily The average output value does not exceed 1,000 yuan; however, the on-site construction efficiency of the concrete sub-item is very high, and the average daily output value can reach up to 20,000 yuan. At present, my country's construction industry is entering the stage of vigorously promoting the industrialization of construction, but the existing prefabricated structure system changes the concrete with high daily averag...

Problems solved by technology

[0002] In traditional cast-in-place concrete structure engineering, the on-site construction efficiency of formwork and reinforcement is very low, and the average daily output value does not exceed 2,300 yuan; the on-site construction efficiency of door and window installation, block filling wall, external insulation and painting is even lower, and the daily The average output value does not exceed 1,000 yuan; however, the on-site construction efficiency of the concrete sub-item is very high, and the average daily output value can reach up to 20,000 yuan

At present, my country's construction industry is entering the stage of vigorously promoting the industrialization of construction, but the existing prefabricated structure system changes the concrete with high daily average output value to the factory, and the formwork, steel bars, external insulation and painting with low output value Most of them are left on site, resulting in slow progress of the construction period and a significant increase in construction costs

In addition, after adopting PC components, the installation process of prefabricated components is added, cross-operation is required for on-site construction, the process increases, and the difficulty of management will increase. Moreover, the assembly integral frame structure system and the assembly integral frame cast-in-place shear force are currently widely used. The actual assembly level of the wall structure system is generally not high, and a large number of formwork, plastering, masonry, steel bars, etc. are still required on site, and the resulting waste, pollution, noise, dust and quality problems are not affected by the use of prefabricated components. fundamental improvement

[0003] Therefore, it is necessary to provide a concrete column and related construction method, so that the premature intervention of a large amount of concrete in the precast concrete structure in the prefabricated beam products of the component factory can be effectively avoided during construction, and the "formwork, steel bars, and pipelines" with low efficiency of traditional on-site construction can be effectively avoided. Part or all of the four major processes of plastering and plastering are completed in the factory at different times and in different places, and the concrete pouring process and procedures with high on-site construction efficiency are still retained on site, which can not only give full play to the advantages of factory production and on-site pouring, but also avoid The deficiency of both
