Technical Field

The invention relates to a rapid building model forming method, and belongs to the technical field of building models.

Background

At present, in building professional teaching, a construction plan is used for teaching a construction site to express construction requirements and conditions, for example, the construction plan is used for expressing arrangement and edge protection of buildings, temporary facilities and various construction machines built on the construction site. The expression mode is not intuitive, a three-dimensional graph cannot be formed after the three-dimensional graph is seen, and the basic information and the mutual relation of each object in the construction site cannot be reflected in an all-round manner.

The materials such as the building model flower bed, the flowerpot, the vase and the like are specially used for greening the environment of the sand table building model, and the landscape materials are crucial in manufacturing the sand table, so that the greening around the building can not be left when the building model is manufactured, and the model design and color matching are needed to be carried out on the greening, so that the building model is more attractive and complete, and the color tone is not lost.

Due to the defects, students are not easy to master the basic contents of a construction site and the overall relation among things in the beginning stage.
