Planting bar glue in the application of the steel

Adhesives are adhesive reinforcement and application principle: is chemically-planted steel bars on the existing reinforced concrete structures or components according to engineering must be reinforced, with appropriate drilling and depth, the chemical adhesive seam an agent to make the new beauty employs firm bonding of steel and concrete, and to make full use of the conditions to determine the tensile strength of steel bar anchoring technology design load of a connection, and the reinforced ( Often referred to as planting bar) Can play to design the desired performance. Effect on the bar and pull through chemical adhesive in the seam an agent to concrete, the craft is simple, the anchoring fast chemically-planted steel bars, safe and reliable, widely used in the structure reinforcement, reinforcement, new and old structure connection, fill after buried steel and buried steel members, etc. Concrete construction craft in order: 1. 1 prepared by the number of engineering parts, steel bar and plastic materials. 1. Payoff positioning: according to the request of design drawing bar and combined with the actual situation on site and determine the position, and make the mark. 1. Planting bar 3 reinforced detection: due to the site location is based on the existing structure design drawings, pay-off, one that new implant inner steel reinforced with the original structure is the situation of the cross. To avoid steel bar and drilling encountered in the original structure, the formation of the waste hole, affecting both the construction efficiency, and may cause certain damage effects on the original structure, so the need on the basis of the original structure of the internal steel on site before drilling exploration, planting bar for drilling work smoothly. 1. 4: drilling in accordance with the requirements of pore size and pore deep drilling, drilling tool USES the electric hammer drill. Planting bar concrete reinforced bar and different size and depth according to the requirements of the construction drawings. 1. 5 hole cleaning: first electric pump to blow out of the hole dust twice, with a wire brush hole cleaning twice, and then electric pump to blow out of the hole dust twice, until no dust to escape. 1. 6 note glue will be installed in the mixing tube material tank in the injection gun, insert the mixing tube to the bottom of the hole, the hole bottom out evenly into the colloid, two-thirds can fill the hole deep. Note glue offshoring uniform injection guns at the same time. Such as more than 20 cm deep hole, mixing tube should be used to extend, guarantee the start from the bottom of the hole injecting, to prevent internal colloid. For the first time from the new type colloid without mixing tube, because there may not be mixed evenly ( Visual colloid color) 。 1. Planting bar 7: after injecting colloidal, reinforced (will be immediately Screw) Pressure rotating slowly to the bottom of the hole, ensure uniform distribution of colloid, visual surface has a small amount of colloid spillover. According to the markup of the prepared test for a desired reinforcement anchoring depth, ( Plant steel reinforcement requirements: reinforcement should be no oil, no serious corrosion. Such as steel corrosion is relatively serious, USES steel wire brush cleaning. Clean up the steel must be clearly marked anchoring depth position. Can damp the hole wall, but must ensure that no MingShui) 。 1. 8 let stand curing: after the steel plant, adhesives are must according to the performance of the curing time of finished product protection, prevent the adhesive bar and the curing time process transition or artificial disturbance influence on the formation has finished planting steel bar. The scene can be set up warning flag, red, white and planting bar and designated persons care curing period of the finished product. 1. 9 quality inspection: the structure of key parts and design requirements for related detection, drawing should be according to the relevant national standard planting steel bar for testing. www。 godjc。 com
