Description

Large bearing steel-wood composite structure transport packing box

technical field

The invention relates to a large-load steel-wood composite structure transport packaging box, in particular to a steel-wood material combined transport packaging box with a load capacity of more than 1000Kg and an inner cavity size of not less than 1000×1000×500.

Background technique

The packaging box is used for product storage and transportation. It should have sufficient strength and certain compression and impact resistance. The product is not damaged, and the packing box has no obvious deformation and damage.

Packaging boxes are widely used in various fields, and the manufacturing technology is relatively mature. However, in some professional fields in China, such as the field of machinery manufacturing, due to the special material and structure of the product, the volume and weight are relatively large, the use of packaging boxes with existing structural types for storage Fortunately, there are the following deficiencies:

(1) The existing packaging boxes are all wooden materials. Not only is the carrying capacity limited for different wooden materials, but also according to the current standards, there are no relevant technical parameters for the carrying capacity of wooden materials, so the reliability of the carrying capacity of the packaging boxes unconfirmed;

(2) The packaging box needs to withstand operations such as lifting, dragging, and forking during transportation. Due to the limited strength of the material and the connection method of the wooden packaging box (gluing, tenon joint, cement nail or wood screw connection, etc.), the box body is often damaged ,damage;

(3) For wooden packing boxes with large carrying capacity, it is necessary to use a large amount of solid wood materials according to the carrying requirements. From the perspective of environmental protection, it is not conducive to environmental development.
