Abstract
The invention relates to the technical filed of building templates, in particular to a regenerated plastic polymer compound hard board which is combined by thermally pressing multiple layers of PVC tablettings, wherein a netting layer is arranged in the PVC tablettings or between the layers of the PVC tablettings. The regenerated plastic polymer compound hard board is economical and low in cost, has the rinsing effect superior to wood templates or steel templates, can be processed in an arc shape, and the arc-shaped board has the strength compared favorably with the steel template. The invention is convenient to assemble and disassemble without large-scale hoisting devices, can be automatically demolded without the release agent, saves the working hour, is water-proof and corrosion-proof, has a revolution number of about 30 times, can be constructed in large areas, can be recycled and processed, has little influence on the environment and completely accords with the requirement on the industrial development in national recycling economy.
Description
Technical field
The present invention relates to the building template technical field, especially a kind of regenerated plastic polymer compound hard board.
Background technology
Realize the high efficiency resource of utilizing in the Life cycle of building, minimally influences environment, has become the leading trend of current building.In recent years, the annual newly-built approximately 2,000,000,000 square metres of buildings of China expect at the bottom of the year two thousand twenty, and national building construction area will increase 40,000,000,000 square metres newly, and it is unprecedented on the world architecture development history that its asd number and construction speed all belong to.In architecture construction and use, need to consume a large amount of natural resources, increase carrying capacity of environment simultaneously, and the critical shortage of the China facing energy and resource, and the severe exacerbation of ecological environment, on the resource regeneration rate again far below developed country.Therefore, press for the various aspects that the theory of sustainable development are incorporated into building field.
Building template is concentrated as a kind of construction material and is used for the construction stage.The building structure of China is based on cast-in-place concrete structure.In the cast-in-place concrete structure engineering construction, building template (the comprising support) important tool that is absolutely necessary.Form work engineering generally accounts for more than 30% of concrete structure engineering cost, accounts for 35% of the Structural Engineering amount of labour used, accounts for the duration about 55%.Abroad, form work engineering expense proportion is higher, and for example in economically developed North America and West Europe, U.S.'s form work engineering expense accounts for 50% of Structural Engineering expense, and Germany is then up to 60%.The building template technology directly has influence on quality, progress and the cost of architectural engineering.At present, the template that Building Trade in China is mainly used has steel form, plank sheathing, Bamboo Formwork, and adopt what material make building template be related to resource utilize cost and to the construction cost of building and cause influence degree to environment.Steel form is mainly used in civilian height and lives outer wall template, pier stud template, science of bridge building plane and special-shaped part, its than great, once infusion of financial resources amount big, maintenance cost is high, use is inconvenient; Plank sheathing, Bamboo Formwork are mainly used in civilian commercial and residential building, plane science of bridge building (mould material thickening), are bonding with phenolic resins or pollopas, one, low toxicity is arranged, its two, the very thin thickness of glue-line, its three, can not bending forming, can not satisfy the requirement of curve modeling.When timber or bamboo wood immersion dilatancy, the extension at break degree of glue-line is far smaller than bamboo wood dilation, so the lamination of coming unstuck will appear in sheet material, Here it is, and the bamboo and wood template is not durable, the main cause that repeat usage is low, and be generally the service life of bamboo and wood template 3～8 times.
Along with fast development of national economy, the urban traffic pressure is outstanding day by day, and setting up viaduct is one of main means of slowing down traffic pressure.In recent years, many viaducts continue to bring out at each crossing, traffic main artery.Wherein, the arc bridge is presented in the people's sight with brand-new form.
The form frame system support of rectangle bridge is set up into rectangle by the profile discrepancy in elevation and is got final product, the formation of just mating formation of common plane template, the installation of form frame system and reinforcing are relatively easy, but the arc bridge is installed the requirement that does not at all reach technical specification and geometric shape according to traditional mould bases.Wherein, common steel form will bend to quite difficulty of many curved profile, and expense is higher; Commonly used wood glue plate, bamboo blanket template be more difficult to bend shaping.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problems of the technologies described above, the invention provides a kind of regenerated plastic polymer compound hard board, its waterproof, anticorrosion, insulate, be easy to secondary forming and make, easy to loading and unloading, cost is low, recyclable processing utilizes once more, meets the requirement of national recycling economy to industry development fully.
The technical solution adopted for the present invention to solve the technical problems is: a kind of regenerated plastic polymer compound hard board, it is composited by the hot pressing of multilayer PVC compressing tablet, in the described PVC compressing tablet or the interlayer of PVC compressing tablet scrim layer is arranged, increased the toughness of material greatly.
Described scrim layer is a glass fiber mesh, cotton yarn is arranged net or steel wire.
The invention has the beneficial effects as follows that a kind of regenerated plastic polymer compound hard board of the present invention is a kind of environment-friendly energy-saving type construction material, economical and practical, cost is low; The clear water effect is better than bamboo plank sheathing, steel form; Can carry out arc processing, the arc timber intensity after the processing can match in excellence or beauty with steel form; Easy to loading and unloadingly do not need large-scale hanging device, but do not need the releasing agent automatic demoulding, save man-hour; Waterproof, anticorrosion, the number of turnover is about 30 times; Large tracts of land is launched construction simultaneously; Recyclable processing utilizes once more, and is little to ambient influnence, meets the requirement of national recycling economy to industry development fully.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the example structure schematic diagram of regenerated plastic polymer compound hard board of the present invention.
Fig. 2 is another example structure schematic diagram of regenerated plastic polymer compound hard board of the present invention.
Among the figure: 1.PVC compressing tablet, 2. scrim layer.
The specific embodiment
A kind of regenerated plastic polymer compound hard board as shown in Figure 1 is composited by 1 hot pressing of multilayer PVC compressing tablet, in the described PVC compressing tablet 1 scrim layer 2 is arranged, and described scrim layer 2 is arranged net for cotton yarn.
Its preparation method is as follows:
When the hard sheet of processing PVC, add cotton yarn and arrange net, form the PVC compressing tablet through adding hot pressing, again multilayer PVC compressing tablet is compounded to form regenerated plastic polymer compound hard board through machine hot pressing.
A kind of regenerated plastic polymer compound hard board as shown in Figure 2 is composited by 1 hot pressing of multilayer PVC compressing tablet, and the interlayer of described PVC compressing tablet 1 has scrim layer 2, and described scrim layer 2 is a glass fiber mesh.
Its preparation method is as follows:
It is some to get the hard sheet of PVC, at every layer or the glass fiber mesh that tiles between the hard sheet of which floor PVC, forms regenerated plastic polymer compound hard board through machine hot pressing.
