The material-saving environment-friendly high-strength light construction formwork that fibrous material strengthens
Technical field
The utility model relates to a kind of construction formwork, particularly the compound construction formwork of a kind of plastic material and fibrous material.
Background technology
At present, the employed template of concreting mainly contains in building operations: steel form, wooden form (Bamboo Formwork) or plastic formwork.
Steel template structure is firm, can reuse, but steel form Heavy Weight, operating difficulties, constructing operation inconvenience, use cost is high.In use have preferably compatibility between steel form and the concrete, need to use release agent to carry out application and process, increase use cost.Corrosion phenomena can occur in itself after steel form used repeatedly, had reduced the availability of template, even can not continue at last to use, and caused the waste of iron and steel resource.Use steel form concreting structure, also need to whitewash the processing of plastering after the demoulding, increase working procedure.
Wooden form or Bamboo Formwork great majority all are can only use once, cause the waste of a large amount of timber (bamboo wood).Easy corrosion after wooden form or the Bamboo Formwork suction, distortion, the continuation that affects template is used.Also need the secondary plastering engineering after using the demoulding of wood (bamboo) template construction.
Common plastic formwork is in use easily aging, yielding, and shock resistance is relatively poor, in use damages easily, has reduced its application life.
Therefore, for advancing the development of green building construction, be necessary very much to research and develop the high-strength material-saving environment-friendly construction formwork of a kind of novel light, to adapt to the development of building trade construction technology.
The utility model content
The material-saving environment-friendly high-strength light construction formwork that the utility model provides a kind of fibrous material to strengthen will solve the technical problem that the operation of existing building template construction is inconvenient, fragile, can not reuse, waste in a large number resource.
The technical scheme that its technical problem that solves the utility model adopts is:
The material-saving environment-friendly high-strength light construction formwork that this fibrous material strengthens comprises sandwich layer, surface layer one and surface layer two, is compounded with enhancement layer one between described sandwich layer front and the surface layer one, is compounded with enhancement layer two between the sandwich layer back side and the surface layer two; Described sandwich layer is foamed plastic plate, and enhancement layer one and enhancement layer two are cloth, and surface layer one and surface layer two are plastic plate.
Bonding and hot pressing is complex as a whole by adhesive for described surface layer one, enhancement layer one, sandwich layer, enhancement layer two and surface layer two.
Described sandwich layer is polypropylene expanded plastic plate, foam polyvinyl chloride plastic plate, styrofoam plate, polyurethane foam plastics plate, polyethylene foam plastic plate or phenolic foam plastic plate.
Described foamed plastic plate is high-strength light skinning type foamed plastic plate.
Described foamed plastic plate is the waste plastic regeneration foamed plastic plate.
Described surface layer one and surface layer two are polypropylene plastics flitch, polyvinyl chloride plastic flitch, polystyrene plastics plate, vinyon plate or polytetrafluoroethylene plastic plate.
Described plastic plate is the waste plastic regeneration plastic plate.
Described cloth is glass fabric, polyurethane fiber cloth, steel fibre cloth or carbon cloth.
The beneficial effects of the utility model are as follows:
The utility model by plastic plate as its surface material, shock resistance, rigidity, fire resistance, water resistance is excellent, finish is higher, is difficult for boning with concrete, is clear-water concrete after the construction, need not the secondary plastering technique.Strengthen through cloth between sandwich layer and the surface layer, higher intensity is provided, increased stability, impact resistance and the rigidity of template, greatly improved its reusable number of times, recycle number of times and can reach more than 200 times, and can make template have certain toughness, but the march surface construction.As its core material, obviously reduce the weight of this template unit area by foams plastic material, made it in use, be convenient to transportation and operation, reduced labour intensity and workload on largely.Foamed plastic plate can adopt high-strength light skinning type, and this kind skinning type foamed plastic has protection against the tide, fire-retardant, the advantage such as modification, ageing resistance be not strong.Surface material and core material all can adopt the materials such as callable polypropylene, and fully recycling after template uses has obviously reduced cost of manufacture, and has saved considerable raw material resources.
The utlity model has good physical and mechanical properties, can repeatedly recycle, apparent density is little, and convenient operation is conducive to improve efficiency of construction, and material-saving environmental can be widely used in concrete pouring construction.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Reference numeral: 1-surface layer one, 2-enhancement layer one, 3-sandwich layer, 4-enhancement layer two, 5-surface layer two.
The specific embodiment
Embodiment is referring to shown in Figure 1, and the material-saving environment-friendly high-strength light construction formwork that this fibrous material strengthens comprises sandwich layer 3, surface layer 1 and surface layer 25.Be compounded with enhancement layer 1 between sandwich layer 3 fronts and the surface layer 1, be compounded with enhancement layer 24 between sandwich layer 3 back sides and the surface layer 25.Bonding and hot pressing is complex as a whole by adhesive for surface layer 1, enhancement layer 1, sandwich layer 3, enhancement layer 24 and surface layer 25.
Described sandwich layer 3 is the polypropylene expanded plastic plate of high-strength light skinning type.Polypropylene expanded plastic plate can be by the polypropylene new material through the double screw extruder foam shaping by extrusion, also can be the waste and old plastics of polypropylene that reclaim, through comminutor again after the granulation again through the double screw extruder foam shaping by extrusion.Sandwich layer 3 also can be foam polyvinyl chloride plastic plate, styrofoam plate, polyurethane foam plastics plate, polyethylene foam plastic plate or phenolic foam plastic plate.
Described surface layer 1 and surface layer 25 are the polypropylene plastics flitch.The polypropylene plastics flitch can be by the polypropylene new material through the double screw extruder extrusion molding, also can be the waste and old plastics of polypropylene that reclaim, through comminutor again after the granulation again through the double screw extruder extrusion molding.Surface layer 1 and surface layer 25 also can be polyvinyl chloride plastic flitch, polystyrene plastics plate, vinyon plate or polytetrafluoroethylene plastic plate.
Described enhancement layer 1 and enhancement layer 24 are cloth, and cloth is glass fabric, polyurethane fiber cloth, steel fibre cloth or carbon cloth, also can be other fiber textile materials.Glass fabric can be glass fibre non-woven or glass fiber mesh.
