Inorganic rear-anchorage inserted bar glue material

Abstract

The invention relates to an inorganic post-anchoring bar-planting adhesive material, wherein a formulation of an inorganic post-anchoring bar-planting adhesive comprises the following compositions in percentage by weight: 61 to 67 percent of common Portland cement, 12 to 21 percent of powdered ore, 5.5 to 6.5 percent of silicon powder, 12 to 15 percent of expansion agent, and 0.08 to 0.1 percent of high-efficiency admixture. As a high-tech environment-friendly material, the inorganic post-anchoring bar-planting adhesive material has the characteristics of ultra-high strength, high temperature resistance, direct welding, suitable operation in water environment, and extremely strong fatigue resistance and durability, and is widely applied to the planting of reinforcing steel bars and bolts during the maintenance and reinforcement of buildings and structures. The adoption of the inorganic post-anchoring bar-planting adhesive material is better than the prior building pre-embedding effect, ensures that structural installation and fixing operations are more convenient, has more broad adaptation range, and solves the bottleneck problems for the anchorage industry, thereby ensuring that the operation is not limited by factors such as environment and so on, greatly improving construction efficiency and speed, and reducing engineering cost at the same time.

Description

technical field [0001] The invention relates to an inorganic post-anchoring material for building, in particular to a formula of an inorganic post-anchor planting bar glue material used for planting steel bars and bolts during maintenance and reinforcement of buildings and structures. Background technique [0002] Post-anchoring in construction refers to drilling holes in the base material through drilling tools or directly placing the anchors in the concrete at the exact position through special tools. In recent years, post-anchoring technology has been widely used in various architectural decoration constructions such as building curtain walls, building reinforcement, and structural reinforcement. There are two basic schemes for post-anchoring: mechanical expansion (such as expansion bolts) and chemical anchoring. [0003] Expansion bolts are one of the earliest rear anchors. Due to their low price, they have been widely used, but they have a large stress on the substrate...
