Embodiment 1

[0058] Take the precast concrete column as a rectangular column as an example for further explanation.

[0059] The present invention provides a prefabricated concrete column with exposed inverted steel bar grouting sleeve and a construction method. The main content of the method includes: prefabricated concrete column, inverted single-hole semi-grouted steel bar sleeve, special hoop type adjustable column bottom metal template, Formwork connecting bolts, cement-based materials, mixing machines, air compressors, grouting equipment and measuring equipment, etc.;

[0060] The exposed inverted steel bar grouting sleeve precast concrete column, the structure of the precast concrete column is a rectangular structure, one end is provided with an assembly tenon, the cross section of the tenon is smaller than that of the column; the size of the tenon matches the inverted single-hole semi-grouted steel reinforced sleeve; A certain length of steel bar with threaded ends is exposed at the oth...

Embodiment 2

[0100] The difference from Example 1 is that the concrete column is cylindrical.

Abstract

The invention provides an exposed inverted steel bar grouting sleeve prefabricated concrete column, and a construction method thereof. One end of the exposed inverted steel bar grouting sleeve prefabricated concrete column is provided with an assembling tenon, the other end is exposed for a certain length, and the end part of the other end is provided with a steel bar provided with threads; the cross section of the assembling tenon is smaller than that of the column; the size of the assembling tenon is designed to match an inverted single hole semi-grouting steel bar sleeve. The construction method comprises following steps: prefabricated concrete column manufacturing, inverted steel bar grouting sleeve installation, installation temporary diagonal bracing, grouting, steel bar sleeve enclosing, and the like. The material of the inverted single hole semi-grouting steel bar sleeve is more convent for processing, purchasing, and storing, and is small in occupied space area, so that prefabricated concrete externally hung wallboard semi-embedded semi-exposed requirements are satisfied, wallboard and main structure deformation adaptation requirements can be satisfied, damage of members under earthquake action is avoided, earthquake proof safety performance is improved, and a problem in the prior art that inner wall surface decoration occupied space is too large because of protrudingof wallboard supports out from the inner wall surface is solved.

Description

Technical field [0001] The invention belongs to the technical field of construction, and relates to a prefabricated concrete column with an assembled exposed inverted steel bar grouting sleeve and a construction method. Background technique [0002] At present, prefabricated concrete structures have become the trend of future building development, and the country has issued prefabricated concrete building application technical regulations, prefabricated building evaluation standards and related supporting national standard atlases, but in prefabricated concrete frame structures, As the most important vertical force-bearing component, concrete columns are prone to major safety hazards if the vertical connection is not strong. When installing prefabricated components, insert the pre-embedded steel bar grouting sleeve from top to bottom into the reserved vertical steel bar. The position of the steel bar and the grouting sleeve cannot be checked, and the grouting density in the steel...
