Problems solved by technology
[0002] At present, fair-faced concrete or stone is mainly used as the main material for decoration in the construction or bridge industry. The disadvantages are: the structure is not stable enough, the earthquake resistance is not good, and it cannot meet the requirements of long-term traffic, sun and rain.
However, when the conventional grouting method is used in the existing GRC decorative board, there is such a problem: shrinkage occurs after the grouting material is hardened

Embodiment Construction
[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0020] GRC is made of alkali-resistant glass fiber as reinforcement, sulphoaluminate low-alkalinity cement as cement and mixed with suitable aggregates to form the base material, and is made by spraying, vertical mold casting, extrusion, flow slurry and other production processes A lightweight, high-strength, high-toughness, multi-functional new inorganic composite material.
[0021] see figure 1 After the GRC board is installed on the steel structure base of the building (or bridge), in order to facilitate the joint between the GRC board and the GRC board and the steel structure base to be filled and dense, the splicing of the GRC board should be done first. Grind the joints, and grind a 50mm wide and 2-3mm deep concave surface on the edge of ...

Abstract
The invention relates to an inner cavity non-shrinking filling technology of a thin-wall art GRC (Glass-fiber Reinforced Composite) board, comprising the following steps of: firstly, carrying out grinding treatment on a seam of the GRC boards; then adhering a carbon fiber mesh fabric to the seam by using epoxy resin so as to seal and plug the seam; and pouring a grouting material to fill the blank between the GRC board and a steel structure basic layer in a layering way. The invention has the following advantages: 1. the combination area of a seam filling body and the grouting layer is enlarged to achieve a firmer integral; and 2. the proper grouting material is selected to fill the blank between the GRC board and the steel structure basic layer in a layering way and the grouting material basically after has no shrinkage after being hardened.
Description
technical field [0001] The invention relates to a cavity filling technology of a decoration material, in particular to a non-shrinkage filling technology of a GRC board cavity. Background technique [0002] At present, fair-faced concrete or stone is mainly used as the main material for decoration in the construction or bridge industry. The disadvantages are: the structure is not stable enough, the earthquake resistance is not good, and it cannot meet the requirements of long-term traffic, sun and rain. [0003] GRC is made of alkali-resistant glass fiber as reinforcement, sulphoaluminate low-alkalinity cement as cement and mixed with suitable aggregates to form the base material, and is made by spraying, vertical mold casting, extrusion, flow slurry and other production processes New inorganic composite materials. As a new type of decorative material, GRC board has broad development prospects due to its light weight, high strength and high toughness. However, when the con...
