Arc-shaped bridge membrane laminating as-cast finish template and production process thereof
The invention relates to an arc-shaped bridge membrane laminating as-cast finish template and a production process thereof. The template comprises melamine impregnated paper, poplar veneers and a core curtain; the arc-shaped bridge membrane laminating as-cast finish template sequentially comprises upper-layer melamine impregnated paper, an upper-layer poplar veneer, the core curtain, a lower-layer poplar veneer and lower-layer melamine impregnated paper from top to bottom; a blank assembling sequence of the core curtain from top to bottom is a long curtain, a long curtain, a short curtain and a long curtain, namely the core curtain totally comprises four layers; the upper-layer poplar veneer is coated with a modified adhesive and is vertically arrayed; the lower-layer poplar veneer is coated with the modified adhesive and is transversely arrayed; and all the layers are compounded into a whole body through gluing and hot pressing. The production process comprises: (1) preparing the melamine impregnated paper; (2) preparing the core curtain; (3) preparing the poplar veneers; (4) assembling a blank of the template; and (5) gluing, hotly pressing and molding. According to the template, a blank assembling structure is adjusted and a surface adhesive type is improved to realize a softening effect, so that the effect that the template can be randomly bent and is not cracked, deformed and broken is realized; and the effect of a manufactured bridge is good and the requirements needed by a curved-surface bridge are met.
