Abstract
The utility model provides a kind of wood-plastic composite building formwork, relate to form for construction engineering technical field, comprise at least two-layer wood and mould substrate, neighboring trees is moulded and is provided with one deck wood between substrate and moulds clamping plate, and template outermost layer is wood moulds substrate, the material that substrate and wood moulds clamping plate moulded by described wood is wood powder and molding powder.The wood-plastic composite building formwork that the utility model provides, overall structure is simple, adopts wood powder and molding powder to be mixed, substantially reduces deadweight, saved shaping consumptive material under the premise calls meeting intensity, mould on clamping plate at wood and through hole is set, reduce further deadweight and the consumptive material of template.The smooth surface of wood-plastic composite building formwork, and concrete compatibility is poor, without the need to covering paper at template surface, ensure that pouring quality, reducing cost of production.
Description
Technical field
The utility model relates to form for construction engineering technical field, particularly relates to a kind of construction formwork adopting wood plastic composite to make.
Background technology
Construction formwork is the temporary layout of one before building in construction work, concrete structure, component is shaped by the position specified, physical dimension, keeps its tram, and bears construction formwork deadweight and effect external load thereon.The object that construction formwork is used for construction work ensures concrete engineering quality and construction safety, accelerating construction progress and reduction engineering cost.
Existing construction formwork generally adopts pure plank to make, meet the requirements to make intensity, pure wooden form is typically provided to solid construction and has certain thickness, be convenient to whitewash to make LIFT surfacing, general needs cover skim paper in order to weaken the compatibility between pure wooden form and concrete on the surface of pure wooden form, make concreting external surface smooth.
The timber that existing pure wooden form expends when producing is many, and needs to add tectorial paper, and cost of production is high, and the weight of pure wooden form self is large, and the deadweight of bearing during use is also large, and pure wooden form is easily out of shape.
Utility model content
In order to solve the shortcoming and defect that above-mentioned prior art exists, the utility model provides the light and wood-plastic composite building formwork that intensity is high of a kind of quality.
In order to reach above-mentioned technical purpose, the wood-plastic composite building formwork that the utility model provides, comprise at least two-layer wood and mould substrate, neighboring trees is moulded and is provided with one deck wood between substrate and moulds clamping plate, and template outermost layer is wood moulds substrate, the thickness direction that clamping plate moulded by described wood is evenly provided with through hole, and the axis of through hole is consistent with the thickness direction that clamping plate moulded by wood.
Wood is moulded substrate and wood and is moulded clamping plate and all adopt wood powder, molding powder mixed injection molding shaping, the deadweight of template is effectively alleviated under the prerequisite ensureing template strength, the surface that substrate moulded by shaping rear wood is comparatively smooth, with compatibility between concrete is poor, surface without the need to moulding substrate at wood after shaping adds tectorial paper, effectively improves production efficiency, reduces cost of production.The thickness direction moulding clamping plate along wood evenly arranges through hole, reduces the weight that clamping plate moulded by wood, thus further reduces the weight of formwork integral, and saved production materials.
It is consistent that through hole axially moulds clamping plate thickness direction with wood, during use, template Impact direction is axially consistent with through hole, wood is moulded the load diatibution that clamping plate are subject to and is moulded the in-plane of clamping plate at wood and can not be distributed on the sidewall of through hole, can effectively avoid pressure break through-hole side wall to cause wood to mould the cracked situation of clamping plate.
Preferably, the flat shape of described through hole is polygon or circle.
Preferably, the flat shape of described through hole is equilateral triangle or regular hexagon.
Through hole is arranged to equilateral triangle or regular hexagon, the load diatibution that template is born is comparatively even, ensures the application life of template.
Preferably, described through hole base area account for that clamping plate base area moulded by wood 20% ~ 80%.
Clamping plate consistency of thickness moulded by via height and wood, the ratio of both base areas is the ratio of both volumes, if the ratio that through hole base area moulds clamping plate base area with wood is less than 20%, then template is to meet the production materials saved under requirement of strength prerequisite few, if the ratio that through hole base area moulds clamping plate base area with wood is greater than 80%, then to mould panel strength little for wood, and template will be caused not meet instructions for use.
Preferably, described wood moulds that substrate is PVC wood plastic plate, plate moulded by PE wood or one in plate moulded by PP wood.
Preferably, described wood moulds that clamping plate are PVC wood plastic plate, plate moulded by PE wood or one in plate moulded by PP wood.
Preferably, the weight ratio of wood powder and molding powder is (4 ~ 8): (6 ~ 2).
Preferably, substrate moulded by described wood is two-layer, and two-layer wood is moulded and arranged one deck wood between substrate and mould clamping plate.
Preferably, described wood is moulded substrate and wood and is moulded between clamping plate and be fixed together by mode that is bonding or coextrusion mold.
Preferably, the thickness of described formwork integral is 12 ~ 25mm.
The wood-plastic composite building formwork that the utility model provides, overall structure is simple, adopts wood powder and molding powder to be mixed, substantially reduces deadweight, saved shaping consumptive material under the premise calls meeting intensity, mould on clamping plate at wood and through hole is set, reduce further deadweight and the consumptive material of template.The smooth surface of wood-plastic composite building formwork, and concrete compatibility is poor, without the need to adding tectorial paper at template surface, ensure that pouring quality, reducing cost of production.
