Description
Technical field
The utility model relates to the polyvinyl-chloride plate material technical field, especially a kind of reinforced polyvinyl chloride hardboard.
Background technology
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, because the building structure of China is based on cast-in-place concrete structure.In the cast-in-place concrete structure engineering construction, the construction formwork 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%.The construction formwork technology directly has influence on quality, progress and the cost of construction work.Adopt what material construction formwork be related to resource utilization, template cost of production and to the construction cost of building and cause influence degree to environment.
At present, the template mainly used of builing industry has steel form, wooden form, Bamboo Formwork.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, be generally 3-8 the application life of bamboo and wood template.
Along with fast development of national economy, the urban traffic pressure is outstanding day by day in addition, and setting up overpass bridge is one of main means of slowing down traffic pressure, and wherein the arc bridge extensively adopts in overpass bridge with its beautiful design.But the arc bridge is for the rectangle bridge, the installation of its form frame system and reinforce more complexly, and the arc bridge is installed according to traditional mould bases, the requirement that does not at all reach technical specification and geometric shape.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.
Therefore, in building and bridge construction industry, it is low to press for a kind of template cost of production; Intensity and pliability are good, can carry out arc processing; Easy to loading and unloading, save the man-hour of constructing; Waterproof, anticorrosion, the number of turnover is many; Recyclable processing utilizes once more, the mould material little to ambient influnence.To improve the quality and the progress of construction project, reduce the construction cost of building and bridge construction engineering, reduce the consumption of natural resource.
The utility model content
The technical problems to be solved in the utility model is: for reducing the construction cost of building and bridge construction engineering, reduce the consumption of natural resource, improve the quality and the progress of construction project, the utility model provides a kind of reinforced polyvinyl chloride hardboard, and its cost of production is low; Intensity and good toughness can carry out arc processing; When being used to make construction formwork, easy to loading and unloading, save the man-hour of constructing, waterproof, anticorrosion, the number of turnover is many; Recyclable processing utilizes once more, and is little to ambient influnence.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of reinforced polyvinyl chloride hardboard, it has several layers polyvinyl chloride compressing tablet, the one or more layers gauze wire cloth of the interlayer of polyvinyl chloride compressing tablet, one or more layers vertical bamboo band and the one or more layers glass fiber mesh that is arranged on the interlayer of polyvinyl chloride compressing tablet that is arranged on the interlayer of polyvinyl chloride compressing tablet of being arranged on, and polyvinyl chloride compressing tablet, gauze wire cloth, vertically bamboo band and glass fiber mesh be by the hot pressing structure that is combined into one.
For further reducing production costs, the primary raw material of described polyvinyl chloride compressing tablet is the waste polyvinyl chloride plastics.
Make for ease of moulding, the thickness of described polyvinyl chloride compressing tablet is 0.3～1.2mm.
To its requirement of strength difference, the thickness of described reinforced polyvinyl chloride hardboard is 8～25mm according to the actual use occasion of sheet material.
The beneficial effects of the utility model are, reinforced polyvinyl chloride hardboard of the present utility model, because the interlayer at the polyvinyl chloride compressing tablet is provided with glass fiber mesh, gauze wire cloth and vertical bamboo band, and it is compound with the polyvinyl chloride compressing tablet by hot pressing, glass fiber mesh, gauze wire cloth and the vertical bamboo band structure that is combined into one, therefore vertical bamboo band, glass fiber mesh, gauze wire cloth and polyvinyl chloride compressing tablet are in conjunction with reliable, vertical bamboo band wherein, glass fiber mesh and gauze wire cloth can improve the intensity and the toughness of reinforced polyvinyl chloride hardboard greatly, particularly can improve the winter pvc material because of low the becoming fragile property phenomenon of environment temperature, improve the flexural strength of reinforced polyvinyl chloride hardboard.This reinforced polyvinyl chloride hardboard is the environment-friendly and energy-efficient constructional materials, and cost of production is low; Can carry out arc processing, the alternative steel form of arc sheet material after the processing; Template is easy to loading and unloading, because lighter weight, thereby does not need large-scale hanging device during the template loading and unloading; But do not need the release agent automatic demoulding in the work progress, save the man-hour of constructing; 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.
