Hebei professional reinforcement engineering company [attention] (Tel: 15931165866 QQ:1613467490 http://www.hbcxjg.com/) [long letter Hebei construction science and Technology Co Ltd -]: for reinforced concrete structures (structures) due to various cracks caused by various reasons, by reinforcing epoxy resin adhesive and filling, in does not affect the production and operation conditions, can achieve the desired intensity, prolong the using life structure, convenient construction, no need of large mechanical operation, safe and reliable reinforcement effect. Hebei professional reinforcement engineering company [] the application principle of attention: Everywhere, concrete cracks can not be avoided, the destruction of buildings is often starts from crack. Therefore, control and treatment is essential to crack. Reinforcement of chemical grouting for cracks using low viscosity, high tensile strength of grouting material, by pressure grouting into the cracks, concrete hole, diffusion, gelling, curing, bonding, composite, component to restore the integrity of purpose, is ideal for in situ Reinforcement technology. Application of crack in concrete structure (temperature crack, shrinkage crack, stress crack, settlement joints), restoring its integrity and function. To crack the load-bearing capacity of the structure caused by inadequate, this treatment, should also take other reinforcement measures, to ensure the safe and reliable structure. Hebei professional reinforcement engineering company [] application range of attention: Repair the building, 1 concrete crack of building apartments, warehouse (wall, column, beam, plate) 2 kinds of storage facilities, tower tank, chimney, other The crack of concrete structure according to its formation can be divided into three categories: 1 stationary crack Refers to the fracture morphology, size and quantity are no longer the stable development. Repair, only repair materials and methods according to the crack size, regardless of other factors. 2 active crack 2 active crack Refers to the width is not stable, cracks easily with the structural stress, deformation or environmental temperature, humidity changes, Zhang shut. Repair, should first eliminate its causes, and observed for a period of time, after the confirmation has been stable, according to the processing method of static crack repair; if not completely eliminate the cause, you should use is flexible enough material for repair. 3 is still in the development of the crack Refers to the development length, width or number still is in, but after a period of time after fracture will be terminated. Refers to the development length, width or number still is in, but after a period of time after fracture will be terminated. To this kind of crack should be to stop its development, we can repair or reinforcement. Hebei professional reinforcement engineering company [attention] crack repair methods are mainly the following four: 1 surface coating sealing (or fiber reinforced surface coating sealing method) Repair glue liquid absorbed by capillary action of concrete surface cracks or micro independent net crack, closed fracture channel. Repair glue liquid absorbed by capillary action of concrete surface cracks or micro independent net crack, closed fracture channel. On the floor and other anti-seepage parts, should be in the concrete surface bonding composite fiber materials to enhance protective effect. 2 low pressure slow injection repairing method (injection) With certain pressure will repair glue into the cracks cavity; this method is suitable for processing still independent cracks, penetrating cracks and honeycomb local defects. 3 pressure grouting method In a certain period of time, with a high pressure perfusion material is pressed into the crack cavity; this method is suitable for processing large structure through crack, honeycomb serious defects of mass concrete and deep and zigzag crack. 4 filling sealing method On the component surface along the crack to straddle cut out U or V shaped groove, and then filled with modified epoxy resin or elastic filling materials, and the fiber composite closed its surface; this method is suitable for processing activities and static crack crack.
