Embodiment

[0045] A connection structure of assembled prefabricated columns, such as figure 1 , including several prefabricated columns 2 perpendicular to the prefabricated base 1 arranged on the prefabricated base 1, the position where the prefabricated base 1 and the prefabricated columns 2 are connected is provided with a number of reinforcement bars 11 protruding from the prefabricated base 1, and the reinforcement 11 runs through the prefabricated base 1 (such as Figure 4 ), the prefabricated column 2 is provided with a prefabricated hole 21 for the insertion of the steel bar 11 (such as Figure 5 ), to facilitate the connection of steel bars 11 and prefabricated columns 2, such as image 3At this time, the outer wall of the lower end of the prefabricated column 2 is provided with a grouting hole 23 communicating with the prefabricated hole 21 and a number of grouting holes 24 extending from the bottom of the prefabricated column 2 to the lower end of the prefabricated hole 21. The...

Abstract

The invention discloses a connecting structure of assembling type prefabricated columns and a construction method thereof, relates to an assembling type concrete structure, and aims to provide the connecting structure of the assembling type prefabricated columns, which has the advantage of enhancing the connecting strength between the prefabricated columns and a prefabricated base layer. The mainpoints of the technical scheme are that the connecting structure of the assembling type prefabricated columns comprises the prefabricated columns which are arranged on the prefabricated base layer; aplurality of reinforcing steel bars which extend out of the prefabricated base layer are arranged at the connecting position between the prefabricated base layer and each prefabricated column; the reinforcing steel bars penetrate through the prefabricated base layer; prefabricated holes for the reinforcing steel bars to insert are formed in each prefabricated column; a soil sealing layer is arranged at the connecting position between the outer wall of each prefabricated column and the prefabricated base layer; a grouting hole which communicates with the prefabricated holes and a plurality of mortar outlet holes which extend to the lower ends of the prefabricated holes are formed in the lower end of each prefabricated column; the grouting hole is positioned in the upper end of the mortar outlet holes and the mortar outlet holes are positioned in the upper end of each soil sealing layer; rubber plugs which are used for sealing the grouting hole and the mortar outlet holes are arranged oneach prefabricated column.

Description

technical field [0001] The invention relates to an assembled concrete structure, in particular to a connection structure of an assembled prefabricated column and a construction method thereof. Background technique [0002] The conventional method of prefabricated frame structure is to prefabricate beams and columns, and cast-in-place nodes. Its characteristic is that the steel bars of beams and columns in all directions are interspersed, intersected, connected and anchored in the core area of ​​nodes. The construction of nodes is difficult, but the structural integrity is good, which can be equivalent to cast-in-place structures. . The vertical reinforcement of the upper and lower columns adopts sleeve butt joint or reserved hole steel grout anchor lap joint, but the main problem is that the lowermost column is connected to the concrete, which requires a stronger connection to support the upper column and beam. Contents of the invention [0003] The object of the present ...
