However, in order to ensure the stability of the structure during the pouring and solidification of concrete, the primary and secondary keels in the formworks of the prior art are often fixedly connected to the support columns, and the primary and secondary keels cannot be removed until the concrete is completely formed, resulting in low recycling efficiency. Summary of the Utility Model

[0003] To solve the above problems, the utility model provides a formwork quick-release device, which supports the keel through a bottom support that can move up and down, and can adjust the bottom support downward to remove the keel in advance before the concrete is completely formed, and recycle the keel. At this time, the top support at the top of the screw supports the formwork to keep the concrete and the formwork stable, and the construction quality is also guaranteed.

[0004] The utility model provides a formwork quick-release device, including: a plurality of threaded columns for supporting between the foundation structure and the formwork, and a formwork for detachably installing on the tops of the plurality of threaded columns. The formwork includes a plurality of primary keels and a plurality of secondary keels, and the plurality of primary keels and the plurality of secondary keels are cross-connected into a grid shape. A clamping groove for clamping the secondary keel is fixed at a position corresponding to each secondary keel on the primary keel. A top support is fixed at the top end of the threaded column, and a bottom support is movably connected to the threaded column. The distance between the bottom support and the top support is adjustable to form a clamping assembly for clamping the primary keel.

[0005] A further improvement of the utility model is that the bottom support is U-shaped and buckled on the lower part of the primary keel.

[0006] A further improvement of the utility model is that the bottom support is movably sleeved on the threaded column, and an internally threaded support member is screwed at a position below the bottom support on the threaded column. By screwing the internally threaded support member, the bottom support is pushed upward.

[0007] A further improvement of the utility model is that the top support is U-shaped and buckled on the upper part of the primary keel.

[0008] A further improvement of the utility model is that both the primary keel and the secondary keel are square steel pipes.

[0009] A further improvement of the utility model is that a support surface for supporting the formwork is formed at the top of the top support.

[0010] A formwork quick-release device of the present utility model supports the keel through a bottom support that can move up and down, and the bottom support can be adjusted downward before the concrete is completely formed to remove the main keel in advance, so as to turnover the keel of the formwork. At this time, the top support supports the formwork to keep the concrete and the formwork stable, and the construction quality is also guaranteed. Brief Description of the Drawings
