Construction method for rear planted wall steel tie

Abstract

The invention discloses a construction method for a rear planted wall steel tie. The main technical process is as follows: measuring the specific position of an original rebar on an anchoring position; demarcating a hole site; drilling a hole according to a specified hole diameter; carrying out borehole cleaning and gluing evenly; before glue is solidified, planting the rebar in a mode of rotating while inserting; respectively leading the rebar and glue as well as the glue and a concrete surface to be combined and cured for 24 hours; and after detecting that the anchored force reaches to design requirements, connecting the planted rebar with the connected rebar by binding and welding. The construction method has simple and convenient operation, low construction cost and reliable construction quality, reduces reserved embedded parts and wastes of steel products, improves the whole construction period effect of construction technology and ensures the earthquake resistance of filled wall bodies; and multiple project practical applications prove that economic and social benefits of the method are remarkable.

Description

technical field [0001] The invention relates to a construction method of tie reinforcement, in particular to a construction method of post-planted wall tie reinforcement adopted during construction. Background technique [0002] According to the requirements of my country's anti-seismic code, in areas with anti-seismic requirements, wall tie bars must be installed in the filling wall. In the past, steel bars or embedded parts were pre-embedded on the walls and concrete frames. This seemingly simple construction measure added a lot of difficulty during construction. For pre-embedded steel bars, it is necessary to chisel the pillars to find the tie bars, which not only damages the appearance quality of the columns, but also has low work efficiency; if pre-embedded parts are installed, the work efficiency is low, and the welding quality is difficult to guarantee. The position of the parts moves, resulting in inaccurate positions of the tie bars. When the masonry material chan...

Problems solved by technology

For pre-embedded steel bars, it is necessary to chisel the pillars to find the tie bars, which not only damages the appearance quality of the columns, but also has low work efficiency; if pre-embedded parts are installed, the work efficiency is low, and the welding quality is difficult to guarantee. The location of the parts moves, causing the tie bars to be inaccurate

When the masonry material changes, the reserved tie bars do not match the modulus of the masonry, and the expansion screws are used or the column stirrups are removed for welding. It is difficult to guarantee the construction quality, which is a problem that has plagued the construction quality of concrete frame structures for a long time.
