The invention is mainly used for the panel in a building template system, in particular to a bare concrete template panel.
Description
Technical field
The present invention relates to a kind of construction formwork veneer, 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, and its distortion is big, the number of turnover is few, 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 invention provides a kind of high-strength light, easy accessibility, be easy to cut, the cost performance height, weather-proof anticorrosion, but durability strong, the exposed concrete building template plywood for panel of the easily demoulding, the many suitability for industrialized production of the number of turnover.
Technical scheme of the present invention is: a kind of exposed concrete building template plywood for panel, comprise overlay film, panel and central layer, described overlay film adopts the resin press mold to make, described panel is formed by densified wood veneer or latex bonded fibre reinforced composite gummed, and described central layer is normal plywood, composite plywood or epoxy glue plywood.
Press molds such as preferred phenolic resins of described overlay film or polyurethane resin.
The raw material that described panel and central layer adopted are mainly fast growing wood, as quick growth poplar wood, China fir, masson pine, pine, birch, Liu An, Eucalyptus etc.
Preferred low-molecular-weight water soluble phenol resin of the used bonding adhesive of densified wood veneer (PF) or melamine formaldehyde resin (MF) also can be other appropriate resin in the described panel, and the densified wood veneer can be one or more layers; The densified wood veneer thickness compares that wood single-plate thickness can suitably reduce in the central layer.
Latex bonded fibre reinforced composite preferred glass fibers felt, glass fabric or basalt fiber cloth also can be carbon cloth or aryl fiber cloth etc. in the described panel, and cloth can be one or more layers.
Described central layer can be normal plywood or integrated timber, also can also can be many seeds epoxy glue plywood for the composite plywood that is formed by common wood veneer and densified wood veneer organic assembling.
All adjacent wood single-plates are vertically laid mutually in the described veneer, and adjacent fiber cloth can be pressed certain angle as required and lay, and follow symmetry shop layer principle simultaneously in whole veneer cross section.
Around the described veneer and the cutting place of punching is 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, central layer mainly in order to support the veneer skeleton and to bear shearing, can improve the dimensional stability of veneer simultaneously.The veneer number of turnover at least 20 times, material 100% can reuse, 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 present invention adapts to the needs of national advanced mould plate technique and construction technology, energy-saving and emission-reduction, integrated structure veneer (Plywood) processing and Wooden modifying treatment 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 invention has the beneficial effects as follows: 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.
