Abstract

The invention provides a steel bar horizontal stress application deviation rectifying method. The root of a steel bar stretching out of a prefabricated concrete component serves as a fulcrum, a horizontal force is applied to the middle of the steel bar stretching out of the prefabricated concrete component through a jack, and a self-balancing loading steel bar deviation rectifying device is designed through a counter force provided by the fulcrum of the root of the steel bar. According to the method, the device is used for limiting the top end of the steel bar stretching out of the prefabricated concrete component, and by virtue of an auxiliary positioning plate, the steel bar stretching out of the prefabricated concrete component is pushed to the position required by steel bar design, sodeviation rectification of the steel bar is achieved.

Description

technical field

[0001] The invention relates to the field of prefabricated buildings, and particularly designs a method for correcting the deviation of steel bars with horizontal force. Background technique

[0002] Grouting sleeve connection is a connection method that is widely used in prefabricated concrete structures. During the grouting construction of semi-grouting sleeves for prefabricated concrete vertically stressed prefabricated components, assembly The steel bars connecting the prefabricated components and the sleeves are easy to bend, so that when the prefabricated components are installed, it is difficult to insert all the steel bars of the lower prefabricated components into the sleeves of the upper prefabricated components at one time. During the on-site installation and construction, it is difficult to insert individual steel bars into the sleeves However, the oxygen cutter is used to cut it off, resulting in a serious decline in the reliability of the assemb...
