Description

The present invention relates to a pier column structure, a pier column system, and an implementation method thereof.

  Conventional bridge structures typically include pier column structures, pier foundations, and bridge structures. The pier foundation is often installed at the base of the pier column structure to provide specific support for the bridge structure, and the pier column is used to directly support the concrete structure of the bridge structure. Bridge structures often adjust the bearing capacity according to different designs, so the pier foundation, pier column structure and bridge structure will be adjusted accordingly. The general pier column structure is usually cylindrical, and its lower part is usually connected to the pier base to form a strong pier concrete structure. When the bridge structure is installed on the pier structure, the bridge structure is completed.

  However, a common pier structure and bridge structure connection method is that the bridge structure and the pier column structure are connected by a grouting method after being installed on a circular pier column by hanging by a precast bridge structure. However, the method of reinforcing bars at the connection point is usually limited by the fact that the connection area is narrow and small, so that the holding force between the reinforcing bar and concrete is usually insufficient, and it can resist external pressure beyond expectations. Can not. Therefore, when a large earthquake occurs, the connection point between the pier and the bridge structure often becomes a damaged part of the bridge. In view of the above problems, the present inventor has a rational and effective design for improving the above-mentioned drawbacks by combining repeated research and operation of academic theory in order to improve and solve the above-mentioned drawbacks. A certain present invention is submitted.

The main objective of this invention is to provide the pier column structure and pier column system which can shorten an enforcement period.

Another object of the present invention is to provide a pier column structure, a pier column system, and a method thereof that can reinforce the retention of reinforced concrete.

The pier column system of the present invention includes a pier column structure and at least one cushion cushion and a bridge structure. The pier column structure includes a main body, at least one concave groove structure, at least one reticulated reinforcement structure, and a fixing plate. The main body has a top surface and a bottom surface, and the top surface and the bottom surface preferably correspond to each other and are parallel to each other, but are not limited thereto. At least one groove structure is installed on the top surface, and the opening of the groove structure is installed on the top surface. Accordingly, the concave groove structure corresponds to the bridge structure by an opening having the same height as the top surface. In addition, the groove structure has a groove bottom surface, which is preferably parallel to the top surface of the main body, but is not limited thereto.
