Glass fiber reinforced concrete stone-like bench and production method thereof

Abstract

The invention discloses a production method of a glass fiber reinforced concrete stone-like bench. The glass fiber reinforced concrete stone-like bench is of a hollow structure and comprises a bench top plate and side supporting plates. The production method of the glass fiber reinforced concrete stone-like bench includes the following steps that a, a mould is made according to a bench model, and the surface and side faces of the mould are sprayed with a colorful decorative finish which is 2-3 mm thick; b, a rebar reinforced layer is arranged, sprayed with a GRC structure which is 2-3 cm thick, and coated with a film to maintain moisture, hydration is promoted, and demoulding is realized in one day; c, film covering is performed for maintenance after demoulding, the outer surface is subjected to acid pickling in one to two days, colors of internal colored sand are exposed, and a semi-finished bench is obtained; d, the semi-finished bench is maintained with water for 1-2 h, the outer surface is smeared with a water repellent agent layer to obtain the stone-like bench. The invention further provides the glass fiber reinforced concrete stone-like bench manufactured through the production method. In this way, the processing steps are simple, and the obtained stone-like bench has the advantages of being low in mass, bright in color and not prone to cracking and having texture like sandstone.

Description

technical field [0001] The invention relates to the technical field of concrete products, in particular to a glass fiber reinforced concrete imitation stone stool and a production method thereof. Background technique [0002] GRC is a kind of fiber cement composite material with alkali-resistant glass fiber as reinforcement material and cement mortar as matrix material. After nearly 30 years of continuous development, GRC production technology has reached a relatively high level. There are many mature production technologies such as high-speed spray-suction molding method, flow-flow method, extrusion method, etc. GRC products are relatively common in the market. There are: GRC decorative products, GRC exterior wall panels, garden landscape products, lightweight partition panels, GRC insulation panels, permanent tubular mandrels for ventilation ducts, permanent templates, industrial building roof components, sound barriers, self-supporting floors, Irrigation channels and pip...

Problems solved by technology

[0003] Existing stools / seats are mainly made of stone, wood and concrete. The disadvantage of stone is that it is heavy and difficult to carry; it is simple in shape, monotonous in color, and lacks a certain aesthetic feeling. Shaped stone stools require a lot of manpower and material resources to cut, carve, etc., and stone is a non-renewable material that has been relatively scarce after years of mining; while wooden stools have poor bearing capacity and weather resistance. In addition, the existing concrete stools are relatively bulky, have poor surface texture, single color, no more beautiful shape, and poor weather resistance, and cracks will occur after a period of use.
