Abstract
The utility model provides a high-strength plywood used for building template panels, which has light weight and high strength, convenient disassembly and assembly, easy cutting, high performance-price ratio, weather resistance and corrosion resistance, strong durability, easy demolding, more turnover number and industrialized production. The high-strength plywood consists of a covering film, a panel and a core board. The covering film is manufactured by pressing resin; the panel is glued by impregnated fiber reinforced composite materials; and the core board is a three-layer board. The plywood is mainly used for the panels in the building template system, particularly the fair-faced concrete building template panels.
Description
Technical field
The utility model relates to a kind of construction formwork high-strength plywood, and main (but not exclusively) is as the panel in the construction formwork system, especially as the Shimizu concrete template panel.
Background technology
Construction formwork is the important tool of concrete structure engineering construction.Statistics shows that in the building course of general concrete structure, form work engineering accounts for 20%～30% of concrete structure engineering cost, accounts for 30%～40% of the amount of labour used, accounts for about 50% of the duration.In the front template operation process, form surfacing commonly used has steel plate panel and traditional bamboo (wood) plywood panel etc., and there are shortcomings such as weight is big, cost is high, dismounting is inconvenient, once have high input in its light plate panel; And traditional bamboo (wood) is though the plywood panel one-time investment is few, but its distortion is big, number of turnover concrete quality few, that processed is not high, be difficult to adapt to the high standard requirement, therefore is used for the higher concrete structure of clear-water concrete or quality requirement and has very big problem.Therefore, be necessary very much to seek a kind of novel building shutter panel material and system.
Summary of the invention
The utility model provides a kind of high-strength light, easy accessibility, be easy to cut, the cost performance height, weather-proof anticorrosion, but durability strong, a kind of high-strength plywood for building shutter panel of the easily demoulding, the many suitability for industrialized production of the number of turnover.
The technical solution of the utility model is: a kind of high-strength plywood for building shutter panel, comprise overlay film, panel and central layer, described overlay film adopts the resin press mold to make, and described panel is formed by latex bonded fibre reinforced composite gummed, and described central layer is the three layer construction plate.
Press molds such as preferred phenolic resins of described overlay film or polyurethane resin.
The raw material that described central layer adopts are mainly fast growing wood, as quick growth poplar wood, China fir, masson pine, pine, birch, Liu An, Eucalyptus etc.
Latex bonded fibre reinforced composite preferred glass fibers felt, glass fabric or basalt fiber cloth in the described panel, also can be carbon cloth or aryl fiber cloth etc., cloth can be one or more layers, and the shop layer angle between the adjacent layer can be set as required, is preferably quadrature arrangement.
The three layer construction plate of described central layer, every layer is preferably integrated material wood-splicing, and vertical mutually by adhesive bonds and texture between three layers, the rift grain direction of two lamina rara externas supports direction perpendicular to building shutter panel.
The cutting edge of described veneer can adopt materials such as plastics, composite material, metal to carry out bound edge, and cut place, the place of punching be the brushing waterproof paint all.
Whole veneer thickness can not waited by 9～30mm, that overlay film mainly plays is weather-proof, waterproof, the raising number of turnover and the effect that improves concrete surface quality, panel mainly provides intensity, rigidity and has waterproof action concurrently, and central layer is mainly in order to support the veneer skeleton and to bear shearing.The veneer number of turnover at least 20 times, material 100% can reuse, nearly 100% can be used as fuel and environmental sound.
Described veneer is mainly used in the panel in the construction formwork system, in particular for the Shimizu concrete template panel.
The utility model adapts to the needs of national advanced mould plate technique and construction technology, energy-saving and emission-reduction, integrated structure veneer (Plywood) processing and advanced composite material technology, the veneer of developing has following advantage: high-strength light, easy accessibility, the number of turnover is many, amortization charge is low, weather-proof anticorrosion, durability strong, the easy demoulding.Therefore, its predominant use is: the substitute products that 1) can be used as the traditional architecture form surfacing.Conventional template existence distortion is big, the number of turnover is few, prop up shortcomings such as tearing workload is big, concrete surface quality difference open, and the veneer among employing the present invention can make a lot of problems be resolved or improve; 2) be used for the Shimizu concrete template panel.Can solve a series of problems such as the weight that has now in the Shimizu concrete template is big, cost is high, dismounting is inconvenient, once have high input.
The beneficial effects of the utility model are: but high-strength light, easy accessibility, be easy to cutting, cost performance height, weather-proof anticorrosion, durability strong, the easily demoulding, the many suitability for industrialized production of the number of turnover; Mainly can be used for the panel in the construction formwork system, in particular for the Shimizu concrete template panel; Can adapt to the different size needs, can be general with external specialty products.
Description of drawings
Fig. 1 is the organigram of the utility model veneer;
Fig. 2 is the assembly schematic diagram of central layer in the utility model veneer;
Fig. 3 is the organigram of central layer in the utility model veneer.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
In the accompanying drawings, 1 is overlay film, and 2 is panel, and 3 is central layer, and 4 is the lamina rara externa in the central layer, and 5 is the inner plating in the central layer.
Shown in Fig. 1,2 and 3, a kind of high-strength plywood for building shutter panel comprises overlay film 1, panel 2 and central layer 3, and veneer thickness is 21mm.Described overlay film 1 is the phenolic resins press mold, and according to requirement such as wear-resisting grade, its press mold amount is 80～200g/m in the veneer front
2, reverse side is about 80g/m
2The thickness of described panel 2 is about 1～3mm, and panel 2 is formed by impregnated glass fibre felt gummed, and is vertical mutually between the adjacent layer; Described central layer is the three layer construction plate, and every layer is integrated material wood-splicing, and vertical mutually by adhesive bonds and texture between lamina rara externa 4 and the inner plating 5, the rift grain direction of two lamina rara externas 4 supports direction perpendicular to building shutter panel.Whole veneer can utilize the one-shot forming of conventional veneer boards technology.Cutting edge at described veneer adopts plastics to carry out bound edge at last, and cut place, the place of punching be the brushing waterproof paint all.
