Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated floor slabs, and in particular relates to a zero-carbon surface material for an assembled decorative curtain wall and a method of using the same. Background Art

[0002] Composite floor slabs typically consist of multiple layers of materials, such as reinforced concrete, steel plates, rebar, wood, or composite materials. These materials are bonded together using adhesives, bolts, and welds to form a single, integrated structure. While composite floor slabs offer increased strength and stability, allowing them to withstand greater loads while reducing the weight of the structure, existing composite floor slabs still have some drawbacks.

[0003] During the construction of composite floor slabs, after the concrete precast base plate is erected, a layer of concrete needs to be poured on its upper surface, which increases the stress on the concrete precast base plate. However, the existing concrete precast base plate overlaps the upper surface of the concrete column, which reduces the contact area between the concrete precast base plate and the concrete column, resulting in a decrease in the bearing capacity of the concrete precast base plate, which can easily lead to excessive stress on the concrete precast base plate and cause fracture, deformation, collapse, etc., thereby affecting the quality of the building.
