Annulated column cap embedded part and construction method thereof

Abstract

The invention discloses an annulated column cap embedded part. The annulated column cap embedded part comprises an embedded steel plate and an anchor bar. The embedded steel plate is provided with vibration holes and vent holes, the vibration holes and the vent holes are evenly distributed, and after the casting and compacting of concrete, the vibration holes are patched through small equal-thickness circular steel plate grooves made of the same materials in a plug welding mode and rubbed down; lower rectangular embedded parts are embedded into the lower surface of a column cap and symmetrically arranged in a cross mode. The invention discloses a construction method of the annulated column cap embedded part. The construction method comprises a positioning control measure and a fixing measure. The accurate anchor bar positioning is guaranteed through partial anchor bar and embedded part synchronous construction, and the construction quality is guaranteed by carrying out multiple bearing, rechecking, checking and accepting in all stages of the whole process, arranging the vent holes in a board of the embedded part. After being finished, the embedded part is firmly fixed, the structural sizes are in the deviation range allowed by the job specifications, and various testing results meet the requirements.

Description

technical field [0001] The invention relates to the field of building components and construction thereof, in particular to a construction method of an annular column cap embedded part and an annular concrete column cap. Background technique [0002] The seat support column in the audience area of ​​a certain project is a special-shaped large circular concrete column. Due to the special consideration of equipment installation and structural safety, a circular column cap is designed on the top of the circular column, and a large number of large buried columns are arranged above and below the column cap. pieces. The embedded part of the annular column cap requires high precision, and the structural form is rare, so it is difficult to guarantee the quality. The main manifestations are: intersecting procedures, difficult to arrange; stirrups, main reinforcement and embedded parts are intersected and difficult to separate; anchor bars of embedded parts are difficult to locate an...

AI Technical Summary

Problems solved by technology

The main manifestations are: intersecting procedures, difficult to arrange; stirrups, main reinforcement and embedded parts are intersected and difficult to separate; anchor bars of embedded parts are difficult to locate and install

[0003] The current construction technology of embedded parts can meet the general construction requirements, but for the embedded parts of the annular column cap of this project, there are more anchor bars in the embedded parts and more steel bars in the column cap. It is difficult to control the spacing and size of the steel bars during actual binding. It is difficult to ensure that the anchor bars pass through the column cap steel bars smoothly and be fixed with advanced embedded parts construction technology, which will eventually lead to the inability to install the embedded parts
