Use of corner code in trough embedded parts


    Force performance of trough embedded parts: its force performance is related to the construction of the corner code. If the corner code is very rigid, the corner code will not bend and deform under the tension, and the anchor rib is in the center tension state. If the rigidity of the corner code is small, the anchor plate will be bent and deformed. In addition to being pulled, the anchoring band will still undergo shear deformation at the root of the anchoring rib, so that the anchoring rib is subjected to internal shearing force, and the curtain wall is partially squeezed by the anchoring rib. Pressure. The size of the shear deformation is related to the degree of bending of the corner code, and the stress of the steel bar at the tension end is the largest, and the distance from the tension end is larger, and the stress is smaller.  

        The main factors affecting the tensile strength of the trough embedded parts: the corner length: the corner code mainly depends on the cohesive force, and the source of the cohesive force is the cementing force, the frictional resistance and the biting force. When the length of the corner code is insufficient, corner code failure occurs, that is, the bond slip is too large or the bond stress exceeds the bond strength, and these two requirements must be met in the engineering design. In the actual structure, when the embedded depth of the anchoring ribs of the embedded parts can not meet the requirements of the specification, additional anchoring measures can be taken at the ends.
