Prefabricated frame column and fabricated building

Abstract

The invention provides a prefabricated frame column and a fabricated building. The prefabricated frame column comprises a column body and a frame rib assembly, the frame rib assembly penetrates through the column body, the two ends of the frame rib assembly extend to the outer side of the column body, the end, extending to the outer side of the column body, of the frame rib assembly is an upper connecting frame, and the other end of the frame rib assembly is a lower connecting frame. The frame rib assembly comprises longitudinal ribs, U-shaped steel ribs and a plurality of first stirrups, and the multiple longitudinal ribs are evenly distributed along the periphery of the column body; the portions, in the column body, of the longitudinal bars are connected through the first stirrups, and the upper connecting frame and the lower connecting frame are arranged at the two ends, extending to the outer side of the column body, of the longitudinal bars correspondingly. The U-shaped steel bars are fixedly arranged in the frame rib assembly through the first stirrups. Compared with the prior art, the prefabricated frame column provided by the invention can replace traditional grouting sleeve or extrusion sleeve connection, the connection mode is low in positioning precision requirement, and a positioning steel plate does not need to be attached.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prefabricated frame column and an assembled building. Background technique [0002] The longitudinal steel bars of prefabricated frame columns in existing prefabricated buildings are generally connected by grouting sleeves or extruded sleeves. First of all, during factory production, the sleeves need to be accurately positioned, and sometimes a positioning steel plate is required for on-site positioning and reservation. Inserting reinforcement, resulting in increased construction costs; traditional prefabricated columns are heavy, and require high tower cranes during on-site construction and hoisting, and it is difficult to connect and align upper and lower columns; professional grouting teams are required to operate, which requires a high professional level Audio-visual recording of the process; there may be a deviation between the positioning of the steel bar an...

AI Technical Summary

Problems solved by technology

[0002] The longitudinal steel bars of prefabricated frame columns in existing prefabricated buildings are generally connected by grouting sleeves or extruded sleeves. First of all, during factory production, the sleeves need to be accurately positioned, and sometimes a positioning steel plate is required for on-site positioning and reservation. The insertion of ribs increases the construction cost; the weight of traditional prefabricated columns is relatively high, and the requirements for tower cranes are high during on-site construction and hoisting; Audio-visual recording of the process; there may be a deviation between the positioning of the steel bar and the sleeve when the vertical steel bar is installed. If the deviation is large, it is necessary to use the bar planting technology or directly scrap the component, which will seriously affect the construction period and cost; there is no relatively reliable one in the country for post-testing. The detection method cannot accurately judge its density and whether it meets the standard, and the general grouting material needs to reach C80, and the cost is relatively high

To sum up, the current grouting sleeve connection and extrusion sleeve connection used for the connection of prefabricated frame columns in my country have problems such as high production precision, difficult installation, insufficient detection methods, and limited professional workers.
