The number of plies that described fiber layer of cloth 3 is arranged in core 1 upper and lower surface both can be consistent also can be inconsistent and also the laying direction and the number of plies fiber layer of cloth 3 can adjust flexibly as required.
Above-mentioned composite material template can adopt hand to stick with paste several different methods manufacturings such as technology, vacuum bag moulding process, vacuum guiding and forming technique or RTM moulding process.
Adopt the template of composite material manufacturing to have the following advantages:
The composite material template has the characteristics of high strength, high rigidity.The panel of composite material template adopts the fibrous material of high strength, high elastic modulus, obtains bigger second moment of area by light-weight filler dexterously again simultaneously, can make the composite material template obtain bigger compressive strength and rigidity, makes template not yielding.
Composite material form surfacing and core bond performance are good, be difficult for to take place that panel and core are peeled off and the phenomenon of flaking.Because the present invention passes through recessing on core, perforate on groove, and in groove and hole, fill up resin.By above construction measure, can obviously strengthen the antistripping ability between panel and the core, improved the cooperative work performance between core and panel, and can obviously improve the resistance to compression and the shear resistance of core, the holistic resistant behavior of composite material template is significantly improved, and glue performance has had huge raising than plywood form.
The composite material template has the characteristics of light weight.By appended Fig. 3 as can be known, core has accounted for the most of volume of template, and the density of this class core own is very low, thereby, can effectively reduce the deadweight of template.Adopt this template to carry out concrete construction, constructor's formwork and form removal can be hand-manipulated, do not take plant equipment, saved machinery expenses, and formwork and form removal speed are obviously accelerated, and improved work efficiency, have saved the engineering time.
Composite material template good corrosion resistance is applicable to the construction of special concrete.The surface that the upper and lower panel of composite material template adopts is covered with cloth, and with the cloth impregnating resin, coheres with core then.Panel so that cloth and resin constitute can prevent the corrosion of all kinds of chemical agent effectively, goes for the concrete construction under the specific condition.As, the concrete construction of harbour engineering, various underwater concrete constructions etc.
The thermal and insulating performance of composite material template is very good, is applicable to the concrete construction of concreting in cold-weather or extremely frigid zones.The core that this template is related as polyurethane foamed material, polyvinyl chloride foam, carbon foam, paulownia wood, cork wood etc., all is the non-conductor of heat, and this makes template possess good thermal and insulating performance.In the winter time or when extremely frigid zones carries out concrete construction, because temperature is low excessively, adopt general bamboo wooden form or steel form, concrete can't be effectively fixed, thereby do not reach the intensity of nominal; If adopting the composite material template constructs, because the thermal and insulating performance of template is very good, the heat in the time of can effectively keeping the concrete hydrating reaction guarantees concrete normal curing, guarantee that it can reach nominal strength, is very beneficial for the concrete construction under the low temperature.
The field machining of composite material template is convenient, and compliance is strong.In some concrete construction, need usually at the scene template to be processed, to adapt to the profile demand of building or works complexity.Steel form inconvenience commonly used is processed at the scene, the rigidity of bamboo wooden form and intensity are limited again, the quality requirement that can not adapt to concrete construction, and the composite material template is when running into complicated concrete construction, only need simple tools at the scene, as cutter, saw etc., just can process suitable shape according to demand.
The turnover access times height of composite material template, long service life.Solidify the formed panel in back by resin and cloth and have higher intensity, can effectively prevent the wearing and tearing in the use.Comparatively speaking, the number of turnover of common bamboo wooden form has only 3~5 times, and the number of turnover of this template can reach more than 20 times.In addition, because closely cohering between panel and core, common various impacts in the template opposing construction, the number of turnover and the application life of greatly improving template.
The demould time of composite material template is fast, easy to maintenance.Employed thermoplastic resin-impregnated fibers material of this template and concrete cohesiveness a little less than, much smaller than caking property between punching block and concrete.Therefore, manually demoulding during concrete demoulding can not use engineering machinery auxiliary, and stripping rate is fast, and demoulding rear pattern plate is easy to maintenance, just can clean template with simple tool.
The repairing of composite material template is convenient.The composite material template is solidified once continuing to have used to two days then if small breakage only need be sealed breakage with cementing agents such as resins, and rehabilitation expense is lower; If big breakage causes and can't repair, the template that intact part can also be cut into fritter has fully improved the utilization rate of template in order to use in the future.
The composite material template surface is smooth, and the planeness height can be used for high-quality Concrete Construction such as " clear water " concrete.Along with the progress of society, people require more and more higher for quality of concrete, and this not only is the requirement on the intensity, also comprises the requirement of concrete type quality, thereby has occurred without " clear water " concrete that need not be decorated after the demoulding.Generally the steel form of Shi Yonging is because its seam is many, and outward appearance often is difficult for reaching " clear water " concrete requirement after the demoulding; And bamboo-wood plywood is out of shape greatly because its rigidity is lower, often also is not easy to reach requirement.The smooth smooth surface of the composite material template that the utility model proposed, less construction Deformation have guaranteed concrete appearance requirement and quality requirement after the demoulding.
The composite material template is with low cost, can save operating expenses.Along with the large-scale production of various fibrous materials in China, its cost descends day by day, has reached the acceptable degree at present; As another composition material of template, core comprises various foams, cork wood etc. in China's large-scale production, and price is very cheap; As the also large-scale production of various resins of adhesive, price is also very cheap.Along with the large-scale production of product, the cost of this template will further reduce.
