Separated type prefabricated reinforced concrete cow-leg pillar and construction method thereof

Abstract

The invention discloses a separated type prefabricated reinforced concrete cow-leg pillar and a construction method of the separated type prefabricated reinforced concrete cow-leg pillar. The separated type prefabricated reinforced concrete cow-leg pillar comprises a prefabricated pillar body and a bracket unit which can be arranged on the pillar body in a later period, wherein a bracket reinforced bar is arranged in the bracket unit, one or more bracket connecting areas is arranged on the pillar body, a pillar body preformed hole is formed in the bracket connecting area, a bracket preformed hole corresponding to the pillar body preformed hole is formed in the bracket unit, the pillar body preformed hole is communicated with the bracket preformed hole, and concrete is poured into the pillar body preformed hole and the bracket preformed hole to realize connection of the bracket unit and the pillar body. A prefabricated method is adopted to overcome the defects that the pillar body can be damaged easily when the bracket is additionally arranged by adopting the anchor bar technology, and the working efficiency is low; and the separated type prefabricated construction method is adopted to overcome the defects that the pressing resistance is high and damage can be easily caused when the fabricated pillar together with the bracket is pressed into the ground.

Description

technical field [0001] The invention relates to the field of building components, in particular to a separate prefabricated reinforced concrete corbel column and a construction method. Background technique [0002] In the reverse construction of underground engineering, the underground structural column can be set by bored piles, and the structural column can also be set by pressing the prefabricated column as a permanent structure of the underground engineering. The above two methods have been applied in underground engineering, and the first method is especially widely used. However, both have certain drawbacks when it comes to setting corbels on a column. Bored cast-in-place piles cannot be poured together with the corbels, and anchor bars need to be added to the corbels in the later stage, which is easy to damage the existing columns during implementation, and the corbels are more complicated. The pouring and maintenance take a long time and reduce the work efficiency; ...

However, both have certain drawbacks when corbels need to be set on a column

The bored piles cannot be poured together with the corbels, and it is necessary to use the anchor bar technology to attach the corbels in the later stage, which is easy to cause damage to the existing columns during implementation, and the corbels are more complicated. The pouring and maintenance take a long time and reduce the work efficiency; When the prefabricated column and the corbel are pressed into the ground as a whole, the pressing resistance increases significantly due to the existence of the corbel. damage
