Problems solved by technology

[0007] Aiming at the installation of existing prefabricated concrete components, 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. The purpose of this invention is to provide a semi-grouting sleeve for prefabricated vertically stressed prefabricated concrete components. Device and method for horizontal correction of steel bars to improve installation efficiency of prefabricated concrete components and construction quality of sleeve connections

Embodiment Construction

[0040] The detailed structure of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] A method for rectifying the deviation of reinforcement horizontally, comprising the following steps: Figure 7 :

[0042] (1) Obtain parameters such as the spacing of steel bars and the thickness of the protective layer of steel bars by reading the design drawings;

[0043] (2) Install the deviation correction device, such as Figure 1-3 shown;

[0044] (3) Place the auxiliary positioning device on the prefabricated component, and adjust the transparent plate of the device to a horizontal state by adjusting the four support rods 16; the auxiliary positioning device is as follows: Figure 4-5 shown;

[0045] (4) According to the design parameters, draw the horizontal auxiliary positioning line 12 and the longitudinal auxiliary positioning line 13 on the panel through the scale 10 attached to the positioning d...

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...
