Anti-falling concrete prefabricated wallboard with strong adhesive force

Abstract

The invention discloses an anti-falling concrete prefabricated wallboard with strong adhesive force, and belongs to the field of concrete wallboards. The anti-falling concrete prefabricated wallboardwith strong adhesive force comprises a pair of concrete prefabricated slab main bodies, wherein a plurality of uniformly distributed grooves are formed in the concrete prefabricated slab main bodies;a plurality of uniformly distributed clamping plates are fixedly connected in the grooves; the clamping plates are filled with waterproof layers; a plurality of uniformly distributed through holes areformed in the clamping plates; the inner walls of the clamping plates are fixedly connected with glue layers; the glue layers are fixedly connected with a plurality of thermoplastic burrs matched with the through holes; and a concrete fiber board is connected between every two adjacent clamping plates. The thermoplastic burrs and the concrete fiber boards can be cured on the concrete board in themanufacturing process, so that the surface of the formed prefabricated slab is rough and has various fiber burrs, the formed concrete board has strong adhesive capacity, and the wall skin is effectively prevented from falling off and cracking.

Description

technical field [0001] The invention relates to the field of concrete wallboards, in particular to a prefabricated concrete wallboard with strong adhesion and anti-falling off. Background technique [0002] Concrete wall panels, wall panels 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, floors, roads, Pools, etc., a wide range of applications. Concrete wall panels are divided into square panels, circular panels and special-shaped panels according to their plane shapes.

[0003] Bamboo wood fiber is cellulose fiber extracted from naturally growing bamboo. It is the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has good air permeability, instant water absorption and strong wear resistance. It has natural antibacterial, antibacterial, anti-mite, deodorant and anti-ultraviolet functions. Therefore, the device is widely used in various aspects. Take a kind of bamboo fiber wallboard as an example. This kind of wallboard on the market today There are many types of such devices, which can basically meet people's needs, but there are still some problems. Most of the traditional wall panels are directly adhered to the wall through concrete, so that after long-term use, the wall panels are easy to fall off, and there are certain problems. safety hazards, and it is inconvenient to use. At the same time, the traditional wall panels of this type have low compression resistance. When impacted, the wall panels are easy to be damaged and deformed, which affects the appearance and affects the use.

[0004] The surface of the current partition board is smooth, and its adhesion is relatively poor. After a long time of use, the wall skin is easy to fall off and crack. In addition, the current partition board uses glass fiber cloth as a reinforcing material and glass fiber as a filler, but Glass fiber and glass fiber cloth not only have high cost, but also have poor alkali resistance. After a long time of use, they are easy to age and fall off, which affects the performance of the product.
