Description

Prefabricated enclosure column and enclosure

Technical Field

The utility model relates to a prefabricated enclosure post and enclosure belongs to architectural design and construction field.

Background

At present, most of the permeable enclosing walls are mainly built in the following ways. Firstly traditional no arrangement of reinforcement brick brickwork, secondly traditional cast-in-place reinforced concrete post, thirdly the enclosure of preassembly construction. First kind brick brickwork enclosure, because masonry material ubiquitous intensity is low, construction speed is slow, and the energy consumption is high, and the work progress building material is extravagant more, and the labour cost is high, and the range of application reduces gradually. The second cast-in-place reinforced concrete column needs to bind reinforcing steel bars on site, manufacture a template, pour in a wet operation on site, and still needs to demold the template and carry out surface layer decoration treatment after the manufacture is finished, so that the construction is long in time consumption and large in site pollution, but the second cast-in-place reinforced concrete column is still a main construction mode at present. The third type of pre-assembled construction enclosure is gradually applied under the national policy guide for the fabricated building. At present, some industrialized prefabricated enclosure walls realize factory processing and manufacturing and standardized construction, and the process level and the construction quality are improved. However, most of the fabricated enclosure walls at the present stage are preassembled by main structure parts, which are generally solid concrete prefabricated columns, so that the fabricated enclosure walls are large in mass and inconvenient to hoist; on the other hand, the way of performing secondary finishing after assembly is still not particularly ideal, since the labor consumption of the secondary operation is large.
