膜结构案例之UA理工学院天井顶棚_膜结构_膜结构车棚

设计师决定尽可能地用最少的材料，为项目打造一个半透明的拉伸膜结构。通过改造，天井墙面向反方向的两端翘起，墙面的边缘设置了金属连接件，以绷紧半透明织物材料，从而形成了一个宛如从内部膨胀出来的泡泡空间。

The project proposes the design of a new space through the use of a translucent stretched textile structure using the least possible material. By tilting the existing walls on the edges of the patio in opposite directions and tightening the translucent fabric on the new perimeter, a space is achieved that seems to expand like a soap bubble from the inside.

项目旨在营造舒适的体感温度环境的同时，保持良好的照明与通风，达到将室外空间转换成室内空间的目的。除了遮风挡雨外，设计师还希望运用当代的建筑语言，重现百年前明亮的天窗景观。

To convert an exterior space into an interior one, lighting and ventilation conditions must be maintained without altering the thermal balance. In addition, it must protect from wind and rain. The idea of the project is to go back in time to the light and bright skylights of more than a hundred years ago, although under a contemporary vision.

顶棚的双曲率形式一方面满足了排水所需的坡度，另一方面提高了建筑的抗风能力。围合墙面采用了加强的PVC材料，另外，墙内的金属圈梁进一步强化了墙面的预应力。织物形成的膜结构，最小厚度可达0.8毫米，最大跨度可达12米。

Double curvature of the roof solves, on the one hand, the slopes necessary for the evacuation of rainwater and, on the other, stability against the action of the wind. The perimeter is reinforced by a metal compression ring through which the reinforced PVC sheet is prestressed. Membrane condition of the textile structure minimizes the thickness: 0.8 mm for a maximum span of 12 m.

织物表面并没有严丝合缝地连接在围合墙面上，而是仿佛漂浮于其上，15厘米的缝隙，同时有利于室内的交叉通风。

The fabric forms a surface that seems to float with respect to its perimeter since it does not touch it and the fact of rounding the perimeter meetings makes the space be perceived as continuous and with diffuse natural lighting. The fabric separates from the wall around its perimeter 15 cm, allowing cross ventilation.
