Problems solved by technology

Most prefabricated structures are connected at the node positions, but the nodes are prone to damage due to the joint action of bending moment, shear force, and axial force, or the requirements of structural force and earthquake resistance can only be guaranteed by making more complex structural forms

Abstract

The invention relates to a prefabricated RC column inflection-point aligned connection method. A prefabricated RC column inflection-point aligned connection device comprises an outer sleeve plate, anouter sleeve and a middle connecting plate; the aligned connection device is prefabricated on a lower column, and high-strength adhesives are poured into a grouting hole and a through hole of the middle connecting plate during assembly; then an upper column is aligned with the lower column to be installed, and an aligning threaded hole is adopted for correction; and a gap between the upper columnand the outer sleeve plate is filled with high-strength adhesives. According to the method, alignment is accurate and convenient, the construction speed is high, enough horizontal shearing force is achieved, and economical efficiency is high; and when the device is applied to the inflection-point position of the column, the effect is obvious, the engineering cost is not remarkably increased, the cost performance is high, and the method is suitable for being widely popularized in engineering.

Description

technical field [0001] The invention relates to a prefabricated assembled RC column anti-bending point alignment connection method, which belongs to the field of structural engineering and is mainly used for assembled RC (that is, prefabricated concrete, a general representative method in the field) column. Background technique [0002] In prefabricated buildings, ensuring good integrity is an inevitable requirement for prefabricated buildings. Most prefabricated structures are connected at the node positions, but the nodes are prone to damage due to the joint action of bending moment, shear force, and axial force, or the requirements of structural force and earthquake resistance can only be guaranteed by making more complex structural forms. To do this, it is necessary to choose an appropriate location for the connection. When beams, slabs, and columns are prefabricated as a whole, since the bending moment at the inflection point is zero, if the prefabricated columns are a...
