Embodiment 1

[0029] Tensile membrane structure teaching model, such as figure 1 as shown, figure 1 It is a schematic diagram of the overall structure of the tensile membrane structure teaching model of the embodiment of the present invention. It includes a working platform 3, a supporting structure 2 and at least one membrane surface 1, the supporting structure 2 is fixed on the working platform 3, and the membrane surface 1 is fixed on the supporting structure 2; Lycra cloth is used to simulate, and different shapes can be formed by stretching around. The application of tension makes the membrane structure have a certain bearing capacity. Feel free to adjust and experience the changes. The main structure is used to control the position of the tension point to control the shape of the tensioned membrane structure.

[0030] Such as figure 2 as shown, figure 2 It is a schematic diagram of a working platform and supporting structure arrangement of a tensioned membrane structure accordi...

Embodiment 2

[0036] A teaching model of tensioned membrane structure, comprising a working platform 3, a supporting structure 2 and at least one layer of membrane surface 1, the supporting structure 2 is fixed on the working platform 3, and the membrane surface 1 is fixed on the supporting structure 2; the material of the working platform 3 is selected as aluminum alloy, and its shape is circular, which is conducive to the arrangement of the struts, and the formed roof shape is more beautiful and diverse.

Abstract

The invention discloses a tensile membrane structure teaching model, comprising a working platform (3), a supporting structure (2) and at least one layer of membrane surface (1), wherein the supporting structure (2) is fixed on the working platform (3); and the membrane surface (1) is fixed on the supporting structure (2). A first hole (31) penetrating the upper and lower parts is formed in the center of the working platform (3). The supporting structure (2) comprises a first supporting rod (21) and at least three second supporting rods (22). The teaching model is low in manufacturing cost and simple in manufacturing, and a student can independently complete all operation, so the teaching model is favorable for teaching popularization.

Description

technical field [0001] The invention belongs to the technical field of model making and relates to a teaching model of a tensile membrane structure. Background technique [0002] The tensioned membrane structure relies on the tensile stress of the membrane itself, together with the support rods and cables to form a mechanism system. The tensile membrane structure carport is made of a variety of high-strength film materials and reinforcing components (steel frames, steel columns or steel cables) in a certain way to generate a certain pre-tensioned stress inside to form a certain spatial shape, as a covering structure, and can be used as a covering structure. A form of space structure that bears certain external loads. [0003] In order to understand this kind of structural system more clearly and intuitively, realize the novel and free characteristics of the membrane structure, and have a certain understanding of its load-bearing principle, relevant teaching models can be us...
