Abstract
The invention discloses an anti-crack construction method for the joint of a filling wall and a frame girder. The method has the advantages that firstly a gap between the frame girder and the upper edge of a brick wall forms a grouting pore channel, and pure cement paste is subjected to double-pressure injection for the second time after M20 cement mortar injected for the first time is initially solidified, so that caves are filled and cracks can be prevented; secondly two through long steel bars are arranged in each of third and second mortar joints in the bottom of the girder and the gap between the frame girder and the upper edge of the brick wall, the two ends of each steel bar are implanted in a column body by more than 100mm, and three supporting lines are formed, so that the temperature stresses of the frame girder and the brick wall can be effectively born and the cracks generated due to the temperature deformation are prevented, wherein the M20 cement mortar adopts 32.2 ordinary Portland cement, and a mass ratio of cement to medium sand to water is 1 to 2.99 to 0.40; and an expansion agent accounting for 9% by mass of the cement is doped, so that the cement mortar has relatively high strength, the temperature stress of the frame girder can be born after the cement mortar matches with the steel bars, and the cracks generated due to the temperature deformation can be effectively prevented.
