Description
Technical field
The present invention relates to construction formwork field, particularly continuous lod construction formwork field.
Background technology
The template adopted in building operations is punching block, wooden model, bamboo mould, plastic formwork etc., wherein, although punching block is firm, and recycle often, but it is expensive, not corrosion-resistant easy get rusty, simultaneously, punching block weight is large, not only transports inconvenience, in work progress, also there is larger potential safety hazard; At present, using maximum in building operations is wooden form or Bamboo Formwork, and this class template is lightweight, is convenient to transport, and its low price, but this kind of template strength is low, not corrosion-resistant, infiltration is rear easy to crack, and the demoulding is difficult, recycles number of times little, be less than 5 times, in addition, this class template is large to Wood demand, causes very big destruction to environment.In recent years, for the defect solving above-mentioned punching block, wooden model, bamboo mould exist as template, a lot of novel plastic template has been there is in industry, as Wood-plastic formwork, GMT template, hollow plastic formwork, foaming PVC template etc., but these templates is expensive, improve building operations cost, and all there is the shortcomings such as intensity is low, poor rigidity, yielding, weatherability is poor, recycle number of times low, about 10 times can only be used.
For solving the defect that above-mentioned template is brought, patent 201110000869.2 discloses a kind of building template reinforced by composite of continuous fiber plastic coated belt material and preparation method thereof, which employs wooden oriented wood chipboard as plate core, solar absorber surface and the enhancing surface layer be made up of 2 ~ 4 layers of continuous fiber plastic coated belt material are together with double-side hot-melt adhesive film heat pressure adhesive, thus make enhancing construction formwork, the hot melt adhesive film one side used is acrylic resin, another side resin is maleic anhydride modified acrylic resin, rely on hot melt adhesive film adhesive sheet core and strengthen surface layer and there is two problems: 1, hot melt adhesive film is expensive, considerably increase building operations cost, 2, the viscose glue preparing wooden oriented wood chipboard is generally thermosetting glue, with PUR bonding and insecure, can there is the phenomenon of foaming, bulge in Long-Time Service, cause the rapid drawdown of template performance.In addition, because shaving board is a kind of flakeboard, although cover fiber reinforcement surface layer on its surface, but still can there is the problem of rigidity deficiency, stratification can occur in its shaving board, cause template strength to be deteriorated, application life shortens.
Another patent 201310422446.9 discloses a kind of construction formwork laminate and manufacture method thereof, described plate core is common fast growing wood veneer, wooden flake board or density fiber board, described enhancing surface layer is the fiber reinforced thermolplastic plate that one side is covered with non-woven fabrics, by glue, the non-woven fabrics and plate core that strengthen facing surface are bonded together, described fiber reinforced thermolplastic plate is that continuous fiber reinforced thermoplastic prepreg and short fiber strengthen thermoplasticity prepreg feed back and lay and form, if the plate core used is fast growing wood veneer, then need the veneer of larger fabric width, just can be processed into the template of high rigidity, processed complex, cost is high, if use shaving board or density fiber board as plate core, then its mechanical strength is inadequate, easily there is stratification in plate in-core.
