With the development of cities, the sand table model plays an increasingly important role in urban construction. When developing a district, real estate developers will first contact some professional sand table model companies to build future display effects. What are the methods and raw materials used for making sand table models in ordinary times? Let's share the raw materials used for the enlargement of common sand table models.
When starting to make the model, the first thing we must consider is the "use method" or "performance method" of the model. According to the "use method", we can determine the policy, proportion, etc. Urban planning, residential area planning and other large-scale models usually use the same proportion as the design drawings.
1. Practice of contour sand table model
The elevation difference of the site is relatively large. When making the model with contour lines, it is necessary to make plates in accordance with the contour lines in proportion in advance, cut along the contour lines, and paste them into terraced terrain. In this case, the materials selected are cork board and styrene paper for convenience, especially styrene blown cardboard, which can be cut into smooth curves with a battery fire thermal cutter.
2. Surface sand table model
If the water surface is not large, it can be treated by simple coloring method. If the area is large, glass plate or transparent plate such as propylene can be used. Under it, colored paper can be pasted or directly colored to show the feeling of water surface. If you want the water surface to feel dynamic, you can use some reflective texture materials to make the surface. The bottom is also colored, giving you a feeling of flowing water.
3. Sand table model of base and construction site
After the proportion is determined, the sand table model can be made. I usually make the model base and base first. If the building site is flat, it is easy to make a model. If the site is uneven and there are adjacent buildings in terms of performance requirements, the model making method will be different according to the different measurement methods.
4. Use cardboard to make model sand table model
Cardboard is a commonly used model material. You can choose different cards according to your needs, such as white card, gray card and color card. Single layer white card is usually used to make straw mold, double layer white card is usually used to make normal mold, gray card can be used to represent the material of plain concrete, and color card is used to represent different finishes.
5. Use wood to make sand table model
Flexible use of the soft and rough talent texture of light wood and the characteristics of convenient processing can make a variety of performance effects.
In fact, there are many methods for sand table model, and different companies use different raw materials. The above is about the method of making sand table models and the materials used. Of course, a good model production company has rich experience in production and many methods.
