Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lifting devices, in particular to a stacking device for transporting composite floors. BACKGROUND

[0002] In the field of construction, composite floors are widely used in various construction projects due to their unique structural advantages. Composite floors are usually composed of a prestressed bottom plate and an upper concrete layer. During transportation and stacking, the safety and stability of the prestressed bottom plate need to be ensured to avoid damage or deformation during handling, which affects the subsequent construction quality and building safety.

[0003] Currently, in the transportation and stacking process of composite floors, the direct stacking method is commonly used, that is, multiple prestressed bottom plates are stacked together. However, this method has many drawbacks. On the one hand, the prestressed bottom plate is directly connected to the upper chord rib plate. During handling and transportation, due to vibration and shaking, the prestressed bottom plate and the upper chord rib plate are prone to collision, resulting in damage to the surface of the prestressed bottom plate, affecting its structural strength and service life. On the other hand, the existing stacking method lacks effective fixing measures, and the stacked prestressed bottom plates are prone to sliding or displacement, which not only increases the difficulty and risk of handling, but also may cause damage to surrounding personnel and equipment. In addition, when multiple stacked prestressed bottom plates need to be hoisted and adjusted in position, due to the lack of convenient operation structure and device, a large amount of manpower and time is often required, reducing the construction efficiency.
