Abstract

The invention relates to a method for determining the flexural capacity of a metal faced straw sandwich board. The method is characterized in that the splints of the sandwich board are metal panels, and the core board of the sandwich board is prepared from straw through the bonding or pouring of the bonding agent. The method of the invention comprises the following steps: collecting the related parameters of the metal faced straw sandwich board, determining the flexibility of the board and determining the flexural capacity of the board. In the method of the invention, the flexibility of the metal faced straw sandwich board under the concentrated load and the flexibility of the metal faced straw sandwich board under the uniform load are determined, and then the maximum theoretical flexibility of the metal faced straw sandwich board is compared with that of the national standard sandwich board to obtain the safety evaluation result of the sandwich board. By adopting the method of the invention, the safety of the metal faced straw sandwich board can be evaluated accurately and the application of the metal faced straw sandwich board can be promoted under the premise of ensuring the safety.

Description

technical field [0001] The invention relates to a method for determining the bending bearing capacity of a sandwich panel and an application thereof, in particular to a method for determining the bending bearing capacity of a metal-faced straw sandwich panel and its application. Background technique [0002] The sandwich panel for metal surface straw heat insulation is composed of two upper and lower thin outer panels (bearing layer, color steel plate) and a light and soft middle layer (core layer, new straw, etc.) through the adhesive Bonded or poured. It has obvious combination advantages, making it an ideal application material for wall panels and roof panels. The metal surface layer has a protective effect on the core layer to avoid mechanical damage, prevent weathering, and isolate water and steam; while the core layer can connect the two surface layers into a whole to bear the load together. During buckling, the core layer can also support the surface layer, increasi...
