Description
Technical field
The invention discloses a kind of composite wood-plastic building template, belong to building material technical field.
Background technology
Since nineteen nineties, architectural structure system has very big change, and monolithic reinforced concrete structure is in building
Proportion is increasing in engineering, and high-rise, high-rise reinforced concrete building largely rises.Cast-in-situ Concrete Structural Engineering
Construction needs to use building template, and the architectural template structure is mainly made up of panel, supporting construction and the part of connector 3.Wherein,
Panel is force bearing plate, is directly contacted with the concrete newly poured, is force bearing plate;Supporting construction is temporary structure, plays supporting surface
The effect of plate, concrete and construction loads；Panel can be connected with supporting construction integral by connector as accessory.Building template
Although a kind of provisional supporting construction, must be made according to design requirement, to ensure concrete structure, component by pre-
Position, shape and the physical dimension shaping of meter, while bear deadweight and external loads.Need to ensure concrete works matter in construction
Amount, construction speed and safe operation, therefore the panel to contacting concrete has higher requirements.Building shutter panel should have enough
Intensity is to ensure the bearing capacity of template system；With enough modulus of elasticity to ensure the integral rigidity of template system.In addition,
The panel of template should surfacing it is smooth, select lightweight durable material as far as possible, can be recycled for multiple times without damage.Wood moulding
Composite（Abbreviation WPC）It is one kind for being prepared by hot-working using various wood fibres and thermoplastic as raw material
Composite.WPC manufacture raw material sources are very extensive, wood machining residues, logging residue, stalk and recovery it is waste and old
Plastics etc. can be utilized, and processing technology is simple, and product uses rear recyclable recycling.WPC researchs start from previous generation
Record the sixties, due to its environmentally friendly, light feature such as high-strength, be rapidly developed since two thousand, application is more and more wider
It is general.WPC plastic matrix is usually polyvinyl chloride of nonpolar polyethylene, polypropylene and low polarity etc., in composite wood system
Top layer is enriched in when standby, makes composite wood surface that inertia be presented, it is not easy to concrete adhesion.
At present, wood plastic composite is mainly used in the industries such as building materials, furniture, logistics packaging, such as manufactures outdoor boardwalk, garden
The products such as woods building, pallet.From the point of view of aspect of performance, wood plastic composite has that light weight, cost are low, intensity is high and size is steady
The qualitative advantage such as good.In addition, surface of wood-plastic composite material is enriched with one layer of plastic matrix, flat smooth, and it is in nonpolar, with solidification
Concrete afterwards can be easily separated.These performances make it possess the potential advantages for building template.But traditional wood plastic building
Be present the problem of mechanical property is bad in template, therefore, also need to its further research.If wood plastic composite largely can should
It is significant to alleviating the problem of China's Forest Resources are nervous and waste plastic pollutes environment in building template industry.
