A Design Research Of The Model Of Wood Plastic Doors And Windows And Its Serialization

As the international energy crisis escalated, loop and in-depth use of resources, and reduce energy loss in the life become the inevitable trend of era development, so the use of recycled plastics and plant fiber leftovers to manufacture high-performance building doors and windows have great significance in the field of energy saving. In addition, by the era of rapid progress, people’s cultural accomplishment and aesthetic temperament are in improving, aesthetic standards are also toward diversified development, so creating artistic value and series of model style will be wood plastic door and window’s design direction.In this paper, take wood plastic doors and windows as the research object, mainly on two aspects of research:first, the model design research of wood plastic doors and windows. Second, the series design research on wood plastic doors and windows, using the quantitative design method. By studying the following conclusions:(1) Wood plastic doors and windows’model design researchUsing two-dimensional grid and combining the mathematical law of quantitative series, arithmetic progression and the principle of symmetry, established a body surface model design with uniform type, two-way progressive type and combined type. The design effect of the uniform type is in a highly normative; two-way progressive type has the sense of rhythm and formed the symmetrical balance; the design effect of the combined type is both rolling and harmonious and unified. Using the method of uniform, the mathematical laws of arithmetic progression, mathematical laws of sequence, inlay type surface’s model design of package and without package is established. And the surface of package inlay has an appropriate proportion size, the mould with the rhythm of the gradient, primary and secondary is properly, with a solid model characteristics; without package inlay has the characteristics of symmetrical beauty, adornment line integral’s feeling is strong, profile is sedate and it has artistic character of collect inside.Using the commensuration rectangle and the non-commensuration rectangular, combined with construction module and the relevant provisions of windows and doors’hole size, mathematical proportion, a rectangular wood plastic door and window facade size system is established, the rectangular window has a clear geometry relationship, also the mathematical is clear, it is facilitate the facade frame design of wood plastic door and window. By the methods of rectangle within the points, the square root halving method, the bilateral halving method. Combined with the law of change and unity in the form, established the facade’s frame design of wood plastic door and window under the condition of rectangular, frame shape formed by containing the same original rectangle scaling factor, overall proportion is very harmonious, and the changes are in order.(2) Wood plastic doors and windows’series design researchUsing two-dimensional grid quantitative and combined with the mathematical method of arithmetic progression and trisection, proposed a series design scheme of gradient shape and rotational shape. The visual effect of the series design scheme of gradient and rotational shapes is unified, it is a kind of series style of external shape similarity and internal structure identical. Using two-dimensional grid and combining the mathematical law of quantitative series and arithmetic progression, put forward the design scheme of outline decoration series, outline decoration series design has the characteristics of gradient, it is a kind of series of style of modeling elements characteristics are the same but constructive methods are in a different way.Using two-dimensional quantitative design method, the mathematical arithmetic progression of grid method, and connecting with the symmetry principle, drawing the series design scheme of curve contour and rectilinear contour of facade, the body of curve contour is smooth, natural transition, it is a kind of series design scheme is of similar model and a same internal structure, rectilinear elevation contour has the characteristics of gradual change, it is a kind of series design scheme of external shape similarity. Using two-dimensional quantitative design method of grid, and connecting with the graphic level shift and symmetry principles, put forward the serialization design scheme of facade decoration of wood plastic door, the design effect is extremely organized and has rich changes, it is a kind of series design scheme of modeling elements are the same and design methods are similar.
