Abstract
A prefabricated segmental concrete filled tube member, and fabrication structure and method using the same are provided. The prefabricated segmental concrete filled tube member has a hollow pipe filled therein with concrete, and a connection flange shaped in a ring radially extending from the peripheries of both ends of the pipe, wherein the segmental concrete filled tube member is integrally connected with another adjacent segmental concrete filled tube member by the connection flange.
Claims11
A prefabricated segmental concrete filled tube member comprising:
- a hollow pipe filled therein with concrete;
- and
- a connection flange shaped in a ring radially extending from the peripheries of both ends of the pipe,
- wherein the segmental concrete filled tube member is integrally connected with another adjacent segmental concrete filled tube member by the connection flange.
A fabrication structure comprising two or more prefabricated segmental concrete filled tube members including a hollow pipe filled therein with concrete, and a connection flange shaped in a ring radially extending from the peripheries of both ends of the pipe, wherein adjacent prefabricated segmental concrete filled tube members are connected with each other in such a way that the adjacent connection flanges are brought into contact with each other, and wherein a filler material is injected through an injection hole formed by grooves provided on opposite surfaces of the adjacent connection flanges, respectively, thereby connecting the adjacent prefabricated segmental concrete filled tube members into one piece.
A fabrication method of a fabrication structure, comprising the steps of:
- (a) lifting a prefabricated coping part of the upper portion of a bridge pier;
- (b) installing a prefabricated segmental concrete filled tube member under the coping part, the segmental concrete filled tube member including a hollow pipe filled therein with concrete, and a connection flange radially extending from the peripheries of both ends of the pipe;
- (c) installing another prefabricated segmental concrete filled tube member under the former prefabricated segmental concrete filled tube member to connect each other such that the connection flange of the latter segmental concrete filled tube member brings in contact with that of the former segmental concrete filled tube member,
- (d) injecting a filler material into an injection hole formed by grooves provided on opposite surfaces of the connection flanges, respectively, and
- (e) repeating the steps (c) and (d).
