Abstract
A plastic faced plywood building template with multiple circulating times relates to building templates and resolves the technical problem that an existing wood template or plywood template is difficult to demould and few in circulating times. A layer of veneering is respectively adhered to the upper surface and the lower surface of a wood plywood of the plastic faced plywood building template, the thickness of the veneering is 0.5mm to 3mm, each player of veneering is composed of a polyolefin material layer and a non-woven fabric layer, and the non-woven fabric layer is located between the wood plywood and the polyolefin material layer. No cement is adhered to the surface of the template, the circulating times are 25 to 30, and the plastic faced plywood building template can be used for construction projects.
Description
Technical field
The present invention relates to a kind of construction formwork.
Background technology
Template is a concrete structure engineering construction necessary tool, and it directly has influence on the economic benefit of quality, speed, cost and the construction enterprises of engineering construction.The main template form of available coagulation soil structure engineering is a plywood form, and the plywood form demoulding in use is difficult, therefore adopts release agent, and the number of turnover of template has only 5～10 times usually, and the number of turnover is low, and this all causes cost to improve.
Summary of the invention
The present invention will solve the technical problem that existing wooden template or the plywood form demoulding in use are difficult, the number of turnover is low, and a kind of plastic-faced plywood construction formwork of the high number of turnover is provided.
The plastic-faced plywood construction formwork of a kind of high number of turnover of the present invention is respectively to paste one deck veneer on the upper and lower surface of wooden plywood; The thickness of veneer is 0.5mm～3mm; Every laminating face is made up of polyolefine material layer and nonwoven, and nonwoven layer is between wooden plywood and polyolefine material layer.
Construction formwork of the present invention obtains the polyolefin veneer in wooden plywood, utilize the low characteristic of polyolefin veneer surface-active; Make the template demoulding easy, need not release agent, the not sticking cement of the template surface after the use; Template does not need to clean, and demould time is short, and any surface finish is prone to cleaning; Corrosion-resistant, do not pollute concrete surface, thereby can cancel plastered work, shorten the duration of fitment operation; And use the number of turnover high, and be 25～30 times, improve 40%～50% than normal plywood template, thereby also reduced the use cost of template.The construction formwork ratio of strength to weight is high simultaneously, thereby makes easy construction and guarantee workmanship; And intensity is high, good toughness, can reduce the usage quantity that construction formwork supports; The template breadth is wide, piece is few, and support and form removal speed are fast.
The plastic-faced plywood construction formwork of the high number of turnover of the present invention can be used in the construction work.
