Concrete precast slab capable of conducting flow and evaporating moisture
Technical Field
The invention relates to the field of buildings, in particular to a concrete precast slab capable of conducting flow and evaporating water.
Background
Reinforced concrete slabs, slabs made of reinforced concrete materials, are basic structures or members in house buildings and various engineering structures, are commonly used as roofs, floor systems, platforms, walls, retaining walls, foundations, terraces, pavements, pools and the like, and have a very wide application range. The reinforced concrete slab is divided into a square slab, a circular slab and a special-shaped slab according to the plane shape. It is divided into a unidirectional plate and a bidirectional plate according to the stress action mode of the structure. The most common are uni-directional plates, four-sided supported bi-directional plates, and flat, beamless plates supported by columns. The thickness of the plate should meet the requirements of strength and rigidity.
The reinforced concrete slab has two types of cast-in-place and prefabrication. Cast-in-place panels are typically integrated with the reinforced concrete beam and form a multi-span continuous structural form. Prefabricated panels are widely used in industrial and civil buildings as roofs and building covers, and the prefabricated panels commonly used have solid, hollow and channel panels, the width of the panels depending on the specific conditions of the local manufacturing, hoisting and transportation equipment.
When the precast slab is used as an outer wall of a building, the precast slab is directly exposed to the external environment, and the requirement on the anti-seepage performance is high, but the existing precast slab is usually started from raw materials only in the forming process, raw materials such as waterproof parts and anti-seepage agents are added, although the existing precast slab has a certain anti-seepage effect, the anti-seepage mode is too passive, the performance of the existing precast slab is gradually reduced along with the passing of the service life, and the water of the existing precast slab is easy to be retained in the slab after the existing precast slab is used for a long time, so that the strength of the slab.
