Abstract
The utility model relates to the technical field of polyvinyl chloride (PVC) boards, particularly a reinforced PVC hard board which comprises a plurality of layers of PVC sheets, wherein glass fiber meshes are arranged inside at least one of the PVC sheets. The reinforced PVC hard board further comprises one or more layers of wire meshes arranged between adjacent PVC sheets, and one or more layers of longitudinal bamboo strips arranged between adjacent PVC sheets, wherein the PVC sheets, the wire meshes and the longitudinal bamboo strips are laminated by hot press to form an integral structure. The utility model solves the technical problems of high construction cost and high natural resource consumption of the construction project of the building and the bridge. The reinforced PVC hard board is excellent in strength and toughness and can be processed in arc shape. The reinforced PVC hard board is used as building formwork with the advantages of convenient dismounting, short construction period, water resistance, corrosion resistance, high turnover rate, recycling and repeated use and less environmental influence.
Description
Technical field
The utility model relates to PVC sheet material technical field, especially a kind of Reinforced PVC 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 the cast-in-situ 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 PVC 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 PVC hardboard, and it has several layers PVC compressing tablet, has at least in a slice PVC compressing tablet to be provided with glass fiber mesh in described PVC compressing tablet; Described Reinforced PVC hardboard also has vertical bamboo band of the interlayer of the gauze wire cloth of the interlayer of the one or more layers PVC of being arranged on compressing tablet, the one or more layers PVC of being arranged on compressing tablet, described PVC compressing tablet, gauze wire cloth and vertically bamboo band by the hot pressing structure that is combined into one.
For further reducing production costs, the primary raw material of described PVC compressing tablet is discarded PVC plastics.
Make for ease of moulding, the thickness of described PVC compressing tablet is 0.3～1.2mm.
To its requirement of strength difference, the thickness of described Reinforced PVC hardboard is 8～25mm according to the actual use occasion of sheet material.
The beneficial effects of the utility model are, Reinforced PVC hardboard of the present utility model, owing in the PVC compressing tablet, be provided with glass fiber mesh, interlayer at the PVC compressing tablet is provided with gauze wire cloth and vertical bamboo band, and it is compound with the PVC compressing tablet by hot pressing, gauze wire cloth and the vertical bamboo band structure that is combined into one, therefore vertical bamboo band, gauze wire cloth and PVC 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 PVC hardboard greatly, particularly can improve winter PVC material because of low the becoming fragile property phenomenon of environment temperature, improve the flexural strength of Reinforced PVC hardboard.This Reinforced PVC 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.
