Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] A composite panel for a shelter, comprising an outer skin 1, an inner skin 2 and an interlayer 3, the interlayer 3 comprising polyurethane foam 3-1, a steel skeleton 3-2 and basswood 3-2 on the outside of the steel skeleton 3-2 3. The rubber layer 4 is arranged between the outer skin 1, the polyurethane foam 3-1 and the basswood 3-3 and bonded with an adhesive, and the outer skin 1 is aluminum alloy.

[0022] Theoretical analysis of feasibility of the present invention:

[0023] When the top layer of the shelter is exposed to high temperature sunlight and the cabin maintains room temperature, the outer skin 1 is subjected to a high thermal load. The elastic modulus of the rubber layer 4 is smaller than that of the aluminum alloy and the polyurethane foam 3-1, and the deformation degree of the aluminum alloy and the polyurethane foam 3...

Abstract

The invention relates to a square cabin composite plate, which comprises an outer skin, an inner skin and a middle sandwich layer, wherein a rubber layer is arranged between the outer skin and the middle sandwich layer. The rubber layer is arranged between the outer skin and the middle sandwich layer, the elasticity modulus of the rubber is much smaller than the elasticity modulus of polyurethane foam and basswood, so the heat stress between the outer skin and the rubber is small, the heat deformation phenomenon is reduced, the debonding problem of the existing square cabin caused by heat deformation at high temperature is solved, meanwhile, the rubber layer, the outer skin, the foam and the basswood are bonded through bonding agents, vibration reduction and buffer effects can be realized between the outer skin and the inner layer framework, the additional stress between the outer skin and the inner layer structure caused by impact and vibration in the transportation process is reduced, and the debonding problem in the transportation process is reduced.

Description

technical field [0001] The invention relates to a composite board, in particular to a shelter composite board. Background technique [0002] The square cabin refers to a workshop that can provide a suitable working environment and safety protection for personnel and equipment, and is convenient for loading, unloading and transportation in various ways. It is also widely used in aerospace measurement and control, field rescue, earthquake relief, petroleum and geological exploration, etc. . The square cabin is an independent box, which can provide a good internal working environment under harsh external environmental conditions, and has a variety of protection capabilities, good maneuverability, and can adapt to various forms of transportation, such as helicopter lifting, motor vehicle transport etc. The composite large-slab shelter is one of the main structural types of the shelter, which is formed by lapping several composite sandwich panels. The existing composite sandwi...
