Abstract:
A kind of non-template column that consisted of prefabricated concrete templates and cast-in-place reinforced concrete was proposed. Prefabricated concrete templates were manufactured in bulk in the factory, then transporting to the construction site to assemble and form prefabricated concrete templates system, and finally pouring concrete into the area to produce a non-template column. Through the experiment on mechanical performance of four non-template short columns and one cast-in-place short column under axial compression, the feasibility of construction technology of non-template short column was investigated. The collaborative performance between prefabricated concrete template and cast-in-place reinforced concrete in the process of experiment was studied. The cracks development process, the failure mode and the bearing capacity of non-template short columns and cast-in-place short column were comparatively analyzed. Meanwhile, some suggestions were put forward in the design and construction of non-template short column. The results show that the construction technology of the non-template short column is simple and feasible, and the collaborative performance between prefabricated concrete templates and cast-in-place reinforced concrete is good. The strength of prefabricated concrete template is not fully utilized, which weakens the bearing capacity of the non-template short column to some extent, but the influence is limited. The influence of the reserved holes on the bearing capacity of the non-template short column is negligible.
