Abstract

The invention relates to the field of underground structure engineering, and discloses a post-inserted steel column guide device. The guide device comprises a plurality of guide plates which are symmetrically arranged around the midperpendicular of a steel column; each guide plate comprises a head part and a tail part connected with the head part, the head part is arranged at the bottom of the steel column, the first side edge of the tail part of the guide plate is arranged on the periphery of the steel column, and the second side edge opposite to the first side edge is parallel to the first side edge; and the steel column is guided by the multiple guide plates to be inserted into a foundation pile reinforcement cage. According to the post-inserted steel column guide device provided by theinvention, by uniformly and symmetrically arranging the multiple guide plates on the periphery of the steel column, it can be ensured that the steel column is smoothly and precisely inserted into a foundation pile in an alignment mode, excessive alignment deviation is avoided, and the situation that construction accidents occur due to the fact that studs are stuck in the foundation pile reinforcement cage is avoided.

Description

technical field [0001] The invention relates to the field of underground structure engineering, in particular to a guide device for steel columns with a rear insertion method. Background technique [0002] In the construction of underground structures, when the post-insertion method is used, it is necessary to insert the prefabricated steel structure column into the reinforcement cage of the cast-in-place bored pile. When the steel structure column (that is, the steel column) is only used as the temporary support column of the foundation pit support, the steel structure lattice column is used, and when the basement is constructed by the reverse method, the steel column needs to be used as the permanent column of the main structure at the same time , the steel column is usually a steel pipe column, and the part anchored into the pile and the basement floor is often provided with shear bolts. Due to the existence of wall protection mud, the foot of the steel column is prone t...
