Abstract
The present invention adopts the distinctive bamboo artificial board resource of China, amassing into veneer, bamboo gummed saw blade plate, bamboo plywood or other as bamboo plywood, thin bamboo strips used for weaving is that the wood-based plate of raw material manufacturing is a base material with the bamboo wood, after fixed thick sanding, the surface of base material respectively coated with the wooden thin plate of drying, several soak phenolic resins or other macromolecule glue after dry paper, in press, make intensity, rigidity height, surface finish is good, wear-resistant, demolding performace is good desirable steel framework construction formwork material after the extrusion forming.
Description
The invention belongs to the manufacturing technology of construction formwork and construction formwork, also belong to wood-based plate secondary processing product and secondary processing product manufacturing technology in the timber industry.
In the construction of some bridges, dam even highrise building,, improve the surface quality of building at present, all adopted advanced high-quality steel framework construction formwork construction technology in order to reduce cost.Fineness for building surface after guaranteeing certain demolding performace and improving the demoulding, except the steel framework of template and connector etc. adopt the metal material manufacturing, the main body of template all is to be base material with wooden multi-plywood at present, and one deck macromolecule material film is then covered on the surface in addition.Because the performance of this film must adapt to concrete physics, chemical property well, so it has determined the face finish quality and the construction cost of steel framework construction formwork construction technology.The covering material that uses has all adopted Visa (Wisa) the template covering material of Finland Schumann company at present, and its manufacture method and composition, prescription all hold in close confidence; And this covering material to the base material defective to cover power lower, therefore the surface quality of base material is required also very highly, more can't use mechanical property to be much higher than wooden plywood but the lower bamboo fiber board base material of surface quality.
The objective of the invention is to utilize the distinctive bamboo artificial board resource of China to make high-performance template product, develop new film covering method and covering material, to reduce dependence and construction cost, improve physics, mechanics and the functional performance of steel framework construction formwork to external product.
Technical solution of the present invention is: adopt bamboo fiber board, as the bamboo plywood that adopts CNZL 87100368 methods to make, the bamboo glue laminated plates (claiming that again thin bamboo strips used for weaving amasss into veneer) that CNZL 88102689.1 methods are made, bamboo gummed saw blade plate (CNZL 89212130.0), bamboo plywood (claiming bamboo weaving lagers stacked material or bamboo curtain board again), or other is that the bamboo fiber board of raw material manufacturing is a base material with the bamboo wood, after fixed thick sanding, on the surface of base material respectively coated with the wooden thin plate (rotary cut venner) of drying, several soak paper dry behind phenolic resins or other macromolecule glue, make the machine direction of the machine direction of wooden thin plate and substrate surface perpendicular during assembly, press molding in press and make intensity, the rigidity height, surface finish is good, wear-resistant, the desirable steel framework construction formwork material that demolding performace is good.
Its detailed process process will be introduced in conjunction with specific embodiments.
