specific example

[0119] In this example, the metal plate is a 2mm thick stainless steel plate, and the size of each metal plate unit is 7m×3m (such as figure 1 As shown), the edge main pipe is the stiffener 2 is φ70×4, the secondary pipe is the stiffener wire 3 is φ30×2, and the distance between the stiffeners is 700mm×700mm.

[0120] The temperature change values ​​of the steel structure in this example are as follows: the temperature rises and changes by 30°C; the temperature drops by 35°C.

[0121] The calculation process is as follows:

[0122] For the convenience of calculation, we consider that the steel structure is very rigid (this is relatively safe for the results), that is, the boundary condition of the plate is very rigid, and the temperature stress of the plate is calculated under this boundary condition. If the temperature stress of this condition meets the requirements, then The overall temperature stress also meets the requirements, because the boundary conditions of the actua...

Abstract

The invention provides a large-grid non-mold molded welding metal curtain wall comprising a stiffening rib which is a metal frame, wherein a metal plate covers the stiffening rib; the metal plate is closely attached with the stiffening rib; and the metal plate is welded on the metal frame or fixed on the metal frame through a fastener. The invention also provides a forming process of the metal curtain wall, comprising the steps of fabricating the stiffening rib system, processing the metal plate with the predetermined shape and shaping the metal plate with any shape on the stiffening rib through a non-mold molding forging process, so that the stiffening rib is connected with the metal plate, and the metal plates in at least one part or all of the metal plate units on the metal curtain wall can be welded into a whole. According to the large-grid non-mold molded welding metal curtain wall, the metal curtain wall in any shape can be fabricated without fabricating a special die, so that a large-grid or ultra-large-grid or seamless metal curtain wall is formed.

Description

technical field [0001] The invention relates to a metal plate curtain wall, in particular to a welded metal curtain wall with large grids without mold. The present invention also relates to the above-mentioned forming process, especially a large-grid non-die forming welded metal curtain wall. Background technique [0002] At present, there are three methods for metal panel curtain wall forming: [0003] The first is to make a steel mold, and then put the metal plate on the steel mold, and then forge it by manual hammering. Due to the continuous change of the special-shaped surface, a large number of steel molds need to be made, which is expensive and the production cycle is too long. It is widely used in engineering. In addition, metal plates, especially the commonly used stainless steel plates, have high hardness and large rebound, making it difficult to shape. [0004] The second is profile rolling forming, which is suitable for relatively regular curved surfaces...
