【正文】 cure important link that crack produce one of conscientiously. The norm stipulates , must cover and keep maintenance warm in 12 hours after the concrete is built at room temperature, ordinary cement is no less than 7 days, if the one that ignored to concrete watered maintenance, on one hand it reduce concrete intensity, on the other hand it make concrete to be in the course of hardening too late to supplement the moisture, therefore lack water and produce the crack in a large amount. So do a good job of watering maintenance of concrete , can already reduce the crack that temperature produces , can also reduce the crack that the concrete shrink and produce . 2, castinplace board don39。t flex freely, so when the constringency of concrete cause to sprinkle knothole stipulation now should the dint exceed certain limit, certanly will cause to sprinkle plank to open crack the crack part take place much at should the dint more concentrated Cape in the placeplank, but is mutually perpendicular with the Overcast angle line of wall 2, construct too early on the castinplace board , add and carry on one39。t establish flexible sew, first floor is the m garage layer, the C20 reinforcing bar cage of the foundation adoption infuses to note a 39。roduction and prevention and cure of the crack of skyscraper Along with the speeding of town house construction step, not a few areas with small residences set up one after another, many inhabitants move continuously into the new residence, their quality to housing request is more and more high, particularly pay attention to very much to some cracks circumstances which sprinkle building plank to appear now, worry these cracks39。s small area39。s shoulder or back the crack caused. norm of inspection of quality of structural construction of concrete stipulates , before the concrete intensity reaches , can39。t pass morning people , pile material , He Shi load , because concrete have a sclerosis course build , just have intensity。s rapid and sustained development of a reinforced concrete structure built, reinforced with the development of technology has been great. Therefore, to promote the use of advanced technology reinforced connecting to improve project quality and speed up the pace of construction, improve labor productivity, reduce costs, and is of great significance. Reinforced steel bars connecting technologies can be divided into two broad categories linking welding machinery and steel. There are six types of welding steel welding methods, and some apply to the prefabricated plant, and some apply to the construction site, some of both apply. There are three types of machinery monly used reinforcement linking method primarily applicable to the construction site. Ways has its own characteristics and different application, and in the continuous development and improvement. In actual production, should be based on specific conditions of work, working environment and technical requirements, the choice of suitable methods to achieve the best overall efficiency. steel mechanical link radial squeeze link Will be a steel sleeve in two sets to
