The embedded steel bars need to be drilled at the beam bottom or the column side die, so that the reserved inserted bars of the constructional column are firm, but the form removal is difficult, the form is basically damaged after being removed, the form cannot be rotated, and the construction cost is greatly increased. The chemical bar planting technology is widely applied to reinforced concrete structure engineering, and although the construction method is convenient, the steel bar is not firmly anchored because the drilling and hole cleaning operations are not standard, and the steel bar cannot play a role in the necessary tie. The drilling depth can not meet the standard and regulation phenomenon in the ubiquitous chemical bar planting process, so that the strength (drawing test) of the anchoring steel bar can not meet the standard value of the standard and the construction quality directly influences the quality of the whole engineering, and potential safety hazards influencing the structure are left for the engineering.

Meanwhile, because the steel bars in the beam column are dense, the steel bars are easy to touch during drilling, and the position must be changed to drill again, so that the chemical steel bars are dislocated, and the surface of the concrete is seriously damaged; thereby increasing the working time and increasing the risk of the driller working aloft. Although the construction method of the structural column by chemical bar planting is convenient, the drilling of the beam slab column becomes an important factor which restricts the construction quality, the construction period and the safety of the structural column. Therefore, a new product and a new process which can not only retain the advantage of convenience of the chemical bar-planting construction method, but also ensure the construction quality of the chemical bar-planting are urgently needed.
