AI Technical Summary
During the pouring of ultra-high concrete columns, the free fall of concrete into the formwork and its collision with the reinforcing steel can easily cause the aggregate and grout to separate, resulting in honeycomb pitting at the base, bottom, or external corners of the column, affecting the appearance quality.
The casting template includes a first semicircular plate and a second semicircular plate, and is equipped with a vibration motor, a sealing mechanism and a locking mechanism. The stability of the template is ensured by locking the sides and ports, and the vibration motor is used to compact the concrete and prevent leakage.
This effectively avoids honeycomb and pitting at the base, bottom, or external corners of the columns, ensuring the appearance quality and compactness of the concrete columns.

TECHNICAL FIELD
[0001] The utility model relates to a pouring formwork, especially a pouring formwork for superhigh concrete column. BACKGROUND
[0002] In construction engineering, the pouring of concrete column is one of the key processes to ensure the stability and safety of building structure, especially for superhigh concrete column (such as core tube column of high-rise building, superhigh frame column, etc.), the construction quality of which is directly related to the bearing capacity and service life of the whole building. In order to ensure the forming quality and dimensional accuracy of concrete column, special pouring formwork for concrete column is needed in the pouring process. These formworks form a closed space by splicing to accommodate and fix the liquid concrete until it hardens.
[0003] When pouring superhigh concrete column, a large number of formworks are usually needed to cover the whole height of the column, so the number and area of formworks are quite large. High columns need to resist large lateral bending forces in mechanics, and the spacing between main reinforcement and stirrup is small, which is not conducive to the self-compaction of slurry in the process of one-time pouring. If the cross section of the column is small, it is more difficult to shorten the height difference between the discharge port and the concrete pouring surface by means of string pipe and chute. The free fall of concrete into the mold and the impact with steel bars will cause the separation of aggregate and paste. If the vibration is not in place or the effect of the vibrating rod is not ideal, it is easy to cause honeycomb and rough surface at the root, bottom or external corner of the column, affecting the appearance quality.

When the first semicircular plate 1 and the second semicircular plate 2 are joined together, the vertical ribs on both sides overlap and are clamped and locked by the side locking mechanism.
[0029] In this embodiment, refer to Figure 4 and Figure 5 The first semicircular plate 1 is symmetrically connected to the front and rear sides with first mounting blocks 6. First splicing blocks 7 are slidably connected to the first mounting blocks 6. The right side of the first splicing block 7 is an inclined surface.
