Description

Technical Field

[0001] The utility model relates to the technical field of building material transportation, in particular to a portable plate clamping device. Background Technique

[0002] There are various types of plates. In construction, the selection of plates depends on the safety, comfort and aesthetics of the building. Among them, plywood is used as the basic structure of walls, floors and roofs, gypsum board is used for the decoration of partition walls, suspended ceilings and interior walls, and composite boards are used for building exterior walls, floors and wall panels. In home decoration, the use of plates mainly considers aesthetics, durability and functionality. For example, oriented strand board, which is made by pressing wood chips with glue, has good bending resistance and strength and is widely used for structural components of walls, floors and roofs, as well as the decoration of interior walls. The use of a large number of plates requires a large amount of transportation and storage of them.

[0003] When transporting plates to the use location, forklifts and trucks are mostly used for transportation, which can meet the needs of medium and small-scale and short-distance transportation inside the warehouse. When at the use location, they are mostly manually carried to the use location. The stacking of plates needs to consider their deformation and moisture absorption. Therefore, it is necessary to ensure that each layer of stacked plates has uniform support to avoid tilting and deformation caused by unstable center of gravity, and it is necessary to use waterproof paper and plastic film for waterproof protection.
