CONSTRUCTION TECHNOLOGY OF ALUMINUM ALLOY FORMWORK AT DOUBLE UNIT DEFORMATION JOINT
Buildings often produce deformation under the action of external factors,leading to cracking and even damage.In order to ensure the safety of the building,many buildings in the design of often reserved expansion joints,settlement joints,seismic joints and other deformation joints,in order to prevent the structural shear damage.The general deformation joint is set in the middle of the two units,the deformation joint is relatively narrow,not easy to template reinforcement.The existing deformation joint construction is the method of internal plug polystyrene board with wall screw reinforcement,which is easy to cause the deformation of polystyrene board in the deformation joint,affecting the construction effect and quality.The stiffness of aluminum alloy template is greater,compared with the polystyrene board concrete pouring process is more difficult to deformation resulting in mold expansion,the concrete forming quality is good.
