Example Embodiment

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0015] like Figure 1-Figure 2 As shown in the figure, a prefabricated and assembled integral frame column bottom grouting structure of the present invention includes a prefabricated frame column and a shear groove arranged at the bottom of the prefabricated frame column. The bottom of the prefabricated frame column is also preset with a grouting sleeve, so The grouting sleeve is arranged around the prefabricated frame column and is used to connect the stressed steel bars of the prefabricated frame column. The lower part of the barrel wall of the grouting sleeve is provided with a grouting hole, and the upper part of the barrel wall of the grouting sleeve is...

Abstract

The invention relates to a prefabricated assembled integral framework column bottom grouting structure, which comprises a prefabricated framework column and an anti-shearing groove formed in the bottom of the prefabricated framework column; a grouting sleeve is prefabricated at the bottom of the prefabricated framework column at the same time, is arranged on the periphery of the prefabricated framework column, and is used for connecting a load-bearing steel bar of the prefabricated framework column; the lower part of the tube wall of the grouting sleeve is provided with a grouting hole; a slurry discharging hole is formed in the upper part of the tube wall of the grouting sleeve, i.e., the slurry discharging hole and the grouting hole are formed in the periphery of the prefabricated framework column from top to bottom; a PVC (polyvinyl chloride) pipe is arranged on the anti-shearing groove, and is arranged in an L shape; the vertical part of the PVC pipe is communicated with the anti-shearing groove; the transverse part of the PVC pipe extends out of the other side of the prefabricated framework column to form a high-position slurry discharging hole; the high-position slurry discharging hole is formed above the slurry discharging hole of the grouting sleeve. The prefabricated assembled integral framework column bottom grouting structure solves the problem that during the prefabricated framework column bottom grouting, air in the anti-shearing groove cannot be thoroughly exhausted.

Description

technical field [0001] The invention relates to a prefabricated integral frame column bottom grouting structure, which belongs to the technical field of building industrialization and prefabrication. Background technique [0002] When using prefabricated frame columns, according to the requirements of the current national code, in order to ensure the transmission of horizontal force at the joints of prefabricated columns, it is necessary to set shear grooves at the bottom of the prefabricated frame columns. Then fill the shear groove with grout when the column reinforcement grouting sleeve is grouted. However, during the grouting process, the shear-resistant grooves have the problem that the air cannot be exhausted, and a cavity will be formed at the bottom of the column, which will weaken the section of the prefabricated frame column, which poses a certain safety hazard. SUMMARY OF THE INVENTION [0003] The invention provides a prefabricated integral frame column bottom...
