Description
Technical field
The utility model relates to the construction formwork 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.
Construction formwork is concentrated as a kind of constructional materials and is used for the building operations stage.The building structure of China is based on cast-in-place concrete structure.In the cast-in-place concrete structure engineering construction, construction formwork (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 construction formwork technology directly has influence on quality, progress and the cost of construction work.At present, the template that Building Trade in China is mainly used has steel form, wooden form, Bamboo Formwork, and adopt what material construction formwork 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, bridge engineering plane and special-shaped part, its than great, once infusion of financial resources amount big, maintenance cost is high, use is inconvenient; Wooden form, Bamboo Formwork are mainly used in civilian commercial and residential building, plane bridge engineering (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 stratification 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 3-8 time the application life of bamboo and wood template.
Along with fast development of national economy, the urban traffic pressure is outstanding day by day, and setting up overpass bridge is one of main means of slowing down traffic pressure.In recent years, many overpass bridges continue to bring out at each crossing, traffic main artery.Wherein, arc bridge one brand-new form is presented in the people's sight.
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.
The utility model content
The technical problems to be solved in the utility model is: the ratio that existing steel form exists is great, once infusion of financial resources amount big, maintenance cost is high, use is inconvenient in order to solve; Wooden form, Bamboo Formwork are owing to be bonding with phenolic resins or pollopas, and the very thin thickness that low toxicity, glue-line are arranged that exists, can not bending forming, can not satisfy the requirement of curve modeling, the technical problem that application life is short, the utility model provide a kind of intensity height, tensile property is good, corrosion-resistant, repeat usage is high regenerated plastic polymer compound hard board.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of regenerated plastic polymer compound hard board, be composited by the hot pressing of upper, middle and lower-ranking material, two layers of material is the some hard sheets of band glass screen cloth regenerated plastic polymer up and down, intermediate layer material is made of hard sheet of several layers regenerated plastic polymer and the vertical bamboo chip layer of several layers, and vertically bamboo chip layer and the hard sheet of regenerated plastic polymer are intervally arranged.
In order to guarantee that regenerated plastic polymer compound hard board has good tensile strength, toughness, satisfy the requirement that different occasions are used, described two layers of material up and down is all for being with stacked the forming of the glass hard sheet of screen cloth regenerated plastic polymer by 3～5; Described intermediate layer material forms for being intervally arranged by 2～5 layers of vertical bamboo chip layer and 1～3 layer of hard sheet of regenerated plastic polymer, and its skin is vertical bamboo chip layer.
For the ease of producing, guarantee the intensity of regenerated plastic polymer compound hard board, the thickness of the hard sheet of described band glass screen cloth regenerated plastic polymer is 0.3～0.6mm; The thickness of the hard sheet of described regenerated plastic polymer is 0.5～0.8mm; The thickness of described vertical bamboo chip layer is 0.5～0.8mm.
In order to reduce cost, improve repeat usage, the primary raw material of described hard sheet of band glass screen cloth regenerated plastic polymer and the hard sheet of regenerated plastic polymer is discarded PVC plastics.
The beneficial effects of the utility model are, a kind of regenerated plastic polymer compound hard board of the present utility model is a kind of environment-friendly energy-saving type constructional materials, and economical and practical, cost is low; The clear water effect is better than bamboo wooden form, 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 release agent automatic demoulding, save man-hour; Waterproof, anticorrosion, the number of turnover is about 30 times; Large tracts of land is launched construction simultaneously; The repeat usage height, little to ambient influnence, meet of the requirement of national recycling economy fully to industry development.
