The present invention relates to a pier construction device using a composite pier form, and more particularly to a pier construction device using a composite pier form for forming a pier through the lifting assembly and separation of the bridge formwork.

In general, the construction method of concrete piers include a climb-form method and a slip-form method of piling up the piers in multiple stages and stacking them from the bottom to the top.

Climb foam method installs the formwork for the formation of the first stage pier at the bottom, and then casts the concrete inside, and after the natural curing for a relatively long time, the strength of the concrete is expressed to a certain level, and then the formwork is dismantled. After the first stage pier is formed, the second stage pier is stacked on top of the cured first stage pier. Repeating this method completes a pier.

However, the climb form method has to install and dismantle the formwork by dividing the total length of the piers by the available height of the formwork, which is not applicable to the construction of high bridges. In addition, because the curing is made by natural curing, the process cycle is long, and in winter, normal construction is difficult due to the poor working environment, the increase in curing cost, and the difficulty in managing the work.

After the formwork is installed on the foundation of the bridge, the slip foam method continuously raises the formwork by using the hydraulic device under the formwork at the speed that the exposed surface of the concrete can be maintained without changing the shape, and then performs reinforcing steel assembly and concrete pouring. When it reaches the top of the piers, it is the construction method to complete the construction by dismantling the formwork.

However, the slip foam method has a disadvantage in that the process for resuming work is very difficult when the work is suspended during construction, so that continuous construction must be performed from the beginning of the bridge formation to the end point when the bridge formation is completed. There are many problems in construction management such as labor costs and equipment costs due to over-injection and satisfying demanding requirements of ready-mixed concrete. In addition, since the curing is made by natural curing, the change in the natural temperature affects the construction speed, so the construction efficiency varies greatly depending on the season, and construction is impossible at all in winter.

Therefore, an object of the present invention is to provide a pier construction device using a composite pier form easy to repeatedly install and dismantle the formwork.

In addition, the present invention has another object to provide a pier construction device using a composite pier form to enable efficient construction without being affected by external environmental conditions by providing a curing system.

The object of the present invention is a frame; Formwork connected to the fixing means provided on the frame upper yoke connection bar; At least one central axis bar located in a vertical direction of a horizontal plane inside or outside of the piers for raising or lowering the formwork; At least one first hydraulic part fixed to the yoke connecting bar and supporting the central shaft bar to raise or lower the frame; And fixed to the yoke of the frame, it is achieved by a pier construction device using a composite pier form comprising a plurality of second hydraulic portion for assembling or separating the formwork to form the pier.
