The invention discloses a production method of building concrete bamboo formworks. The production method comprises the following steps: 1, curtain manufacturing: weaving bamboo chips of which the thicknesses are smaller than or equal to 1.5 into bamboo curtains, and
drying the bamboo curtains until the
water content is smaller than or equal to 10%; 2, gum dipping: dipping the dried bamboo curtains with gum for 20 minutes, and secondarily
drying the bamboo curtains until the
water content is 12% after gum dipping; 3, plywood manufacturing: pre-pressing high-
polymer plastics into plywood of which the thicknesses are smaller than or equal to 2 mm, and
coating a single surface of each piece of plywood with gum for subsequent use; 4, blank assembling: spreading the high-
polymer plastic bottom plate of which a gum surface faces upwards, laying the bamboo curtains layer by layer, and spreading the high-
polymer plastic face plate of which a gum surface faces downwards; 5,
hot pressing: feeding a plate blank into a
hot press, and gluing and forming at high temperature under
high pressure; and 6, edge trimming: carrying out edge trimming to obtain the final products. Gaps among the adjacent bamboo curtains are filled owing to hot melting of the upper high-polymer plastic plate and the lower high-polymer plastic plate. The invention aims to provide the production method of the building concrete bamboo formworks. Density and
mechanical strength are uniform, a separation layer does not exist, the structure is firm, the
shear strength is high, the surface is smooth so that water cannot permeate easily, and the service life is greatly prolonged.
