Planting bar adhesive reinforcement and construction points for attention

Planting bar glue adhesives are steel construction matters needing attention matters needing attention of construction 1 bar and drilling ensure drill, drill and implanted steel ( Screw) The pull force in the same direction. Guarantee the accuracy of the aperture and deep hole size. 2 drilling should avoid the original structure reinforcement, especially of the prestressed steel and the main force. Adhesives are 3 before construction, reinforced detectors should be used to pinpoint the original structure reinforcement. 4 for beam-column joints reinforced dense or not easy to accurately detect areas, such as advice, according to the original structure design drawing of steel bar distribution and comply with the original concrete interface treatment ( Cut hair, roughness) The process of the construction site observation analysis, fixing the original structure reinforcement; 5 when drilling, if drill, a sudden stop or bit not forward, should immediately stop drilling, check whether the internal reinforcement. 6 for more than 15 d ultra deep hole drilling, in addition to the standard operation of electric hammer is not big pressure, also often should lift drill, let debris discharge in a timely manner. 7 note glue such as more than 20 cm deep hole, mixing tube should be used to extend, guarantee from the bottom of the hole injecting, to prevent internal colloid. 8 reference curing schedule, strictly abide by the installation time and curing time and colloidal cured before carrying, disturbance are strictly prohibited during solidification, in case of invalidation. 9 injection bar and beautiful seam an agent shall be deposited with a cool, dry place, avoid direct sunlight, long-term storage temperature is 5 ℃ ~ 25 ℃. Pay attention to the seam an agent injection do not contact with eyes. 10 if hole wall wet ( There should be no MingShui) Planting bar, can take note glue, but the curing time should be according to the curing schedule listed in the double extended.
