Alternative grouting method for steel-structure column feet

Abstract

The invention discloses an alternative grouting method for steel-structure column feet. The alternative grouting method comprises the following steps: arranging a template; sequentially and uniformlyforming N grouting holes in the upper part of the template at the first side of the original column feet, wherein N grouting holes comprise first grouting hole to N-th grouting holes, and N is greaterthan 1; sequentially and uniformly forming N overflow holes in the upper part of the template at the second side of the original column feet, wherein the N overflow holes comprise first overflow holeto N-th overflow hole, and the first overflow hole and the first grouting hole are oppositely formed; alternatively grouting, selecting an integer M from one to N sequentially, sealing other groutingholes except from the M-th grouting hole, grouting the M-th grouting hole until slurry overflows from the M-th overflow hole; repeatedly grouting, selecting the integer M from one to N sequentially,sealing other grouting holes except from the M-th grouting hole, grouting the M-th grouting hole until the slurry overflows from the N-th overflow hole. The alternative grouting method is used to sequentially grout the grouting holes until the corresponding overflow holes overflow, so that the grouting is more compact. The more stable and safer structure is guaranteed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a grouting method for steel structure column feet. Background technique [0002] Steel structure construction often has a column base grouting process. After the steel structure column base is installed and the bolts are fixed, gaps are reserved at the bottom, and the gaps are sealed and compacted with high-strength non-shrinkage grouting materials. Due to the heavy load on the upper part of many steel structures, it is not allowed to reserve grouting holes or open holes on the horizontal steel plate at the base of the column. The grouting can only be injected from the side gaps, resulting in the inability to be densely grouted and affecting the safety of the structure. [0003] For this reason, it is necessary to provide a more compact steel structure column foot grouting method to ensure that the structure is more stable and safe.
