Fluff anti-seepage type concrete slab for building external wall

Abstract

The invention discloses a fluff anti-seepage type concrete slab for a building external wall, and belongs to the technical field of buildings. According to the fluff anti-seepage type concrete slab for the building external wall, fluff-like water guide air bag bars similar to fluff can be disposed on the outer surface of a concrete slab, waterproofing is realized for the surface at a normal state,the contact between rainwater and the concrete slab is reduced, and therefore a certain anti-seepage effect is realized, even when a slight water seepage phenomenon occurs, self-releasing water storage balls buried corresponding to the fluff-like water guide air bag bars rapidly absorb water and trigger drainage actions to inject air into the fluff-like water guide air bag bars on the basis of internal extrusion and to make the fluff-like water guide air bag bars get hard and straight, meanwhile the self-releasing water storage balls release the absorbed water, the water is rapidly guided outof the concrete slab with the aid of the fluff-like water guide air bag bars, and the contact area between the water and the outside is increased at the same time, so that water evaporation is accelerated, the rapid drying of the surface of the concrete slab can be promoted, the rainwater can hardly continue to seep into the concrete slab, and the anti-seepage performance of the concrete slab isgreatly improved.

Description

technical field [0001] The invention relates to the technical field of construction, and more specifically relates to a concrete slab for an anti-seepage type building exterior wall. 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 ...

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 seepage 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, or in the face of more rainy seasons, relying solely on prefabricated The impermeability performance of the board itself is often less effective
