Concrete precast slab capable of guiding and evaporating water

Abstract

The invention discloses a concrete precast slab capable of guiding and evaporating water, and belongs to the field of buildings. The concrete precast slab capable of guiding and evaporating water comprises a concrete slab main body, wherein a plurality of flow guiding grooves are formed in the concrete slab main body; flow guiding channels are mounted in the flow guiding grooves; fiber cloth belts which are matched with the concrete slab main body are fixedly connected to openings of the flow guiding channels; a plurality of floating blocks which are uniformly distributed are fixedly connected to the inner walls of the flow guiding channels; each floating block comprises a fixing plate which is fixedly connected to the corresponding flow guiding channel; water absorbent resin is fixedly connected to each fixing plate; a floating film is laid on the surface of each water absorbent resin; a plurality of surface cooling balls which are uniformly distributed are fixedly connected to the fiber cloth belts; each surface cooling ball comprises an expansion ball; and a fixing ball is arranged in each expansion ball. When water flow on a concrete slab is guided to be drained, evaporation of water on the surface of the concrete slab can be accelerated, accumulation of the water on the concrete slab is prevented, and rainwater is prevented from permeating into the concrete slab.

Description

technical field [0001] The invention relates to the field of construction, more specifically, to a concrete prefabricated slab capable of guiding water and evaporating water. Background technique [0002] Reinforced concrete slabs, slabs made of reinforced concrete materials, are basic structures or components in building construction and various engineering structures, and are often used as roofs, floors, platforms, walls, retaining walls, foundations, floors, and pavements , pools, etc., a wide range of applications. Reinforced concrete slabs are divided into square slabs, circular slabs and special-shaped slabs according to their plane shapes. According to the force action mode of the structure, it is divided into one-way plate and two-way plate. The most common are one-way slabs, two-way slabs supported on four sides, and beamless slabs supported by columns. The thickness of the plate should meet the strength and rigidity requirements. [0003] There are two types of...

Problems solved by technology

[0004] When prefabricated panels are used as building exterior walls, because they are directly exposed to the external environment, they have high requirements for anti-seepage performance. Raw materials such as permeation agents have a certain anti-seepage effect, but the anti-seepage method is too passive, and with the passage of service life, its performance gradually declines, making it easy for the board to retain moisture in the board under long-term use. affect the strength of the board
