[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The wood panel is replaced by the bio-based polyamide composite board, the thickness of which is only 3mm, far less than the thickness of the wood panel 15mm, the installation difficulty of the panel in the later period is reduced, and the anchor screw is more economical; the bio-based polyamide composite board has a very small tolerance, only an error of ±0.1mm, and lays a good foundation for the forming of concrete. Furthermore, the bio-based polyamide composite board is lightweight, only 2 / 3 of the aluminum frame, and can greatly reduce the working strength of the laborer; the bio-based polyamide composite board is a hydrophobic material and does not react with concrete chemically, so it is not necessary to brush release agent; the bio-based polyamide composite board has high strength and large rigidity, and the turnover frequency can reach more than 50 times, far exceeding the service life of the wood panel, and is not prone to bulging and cracking. The bio-based polyamide composite board is entirely derived from biomass, and the source is sustainable and recyclable.

[0012] The utility model discloses a horizontal reinforcing rib can improve the strength of the composite formwork and prolong its service life.

[0013] The utility model discloses a bottom plugging assembly can plug the gap between the composite formwork and the ground, prevent concrete from leaking, improve the pouring quality, prevent the phenomenon of slag and rotten root, simultaneously, the bottom plugging assembly of the utility model can adjust the elongation of rubber sealing piece, and then adapt to the gap of different thickness, the utility model discloses a adjusting bolt can fix the bottom of rubber sealing piece firmly on the ground, guarantee that rubber sealing piece does not bend due to the pressure of concrete, and then lead to plugging failure, the utility model discloses a guide sleeve on the second clamping plate, through the cooperation of guide sleeve and adjusting bolt, effectively guarantee the vertical lifting of the bottom of rubber sealing piece, and then guarantee the full contact of the bottom of rubber sealing piece and the ground, guarantee the pouring quality.
