. PAGE . Shallowly discusses the construction joint processing Introduction Massive engineering structure shakes harms the example to indicate that, the portal frame construction pitch point universal destruction is heavier, often causes the structure to expire, the Chinese and foreign scholar analyzes indicated, this is the various reason, including the design fault, has not strengthened the pitch point intensity, realizes reason and so on strong pitch point strong anchor. Simultaneously constructs also has the construction quality weakness, difficulty with guarantees the design anticipated target. In construction new old concrete construction gap time, continues the surface position, continues the surface processing method, the new old coagulation locally born ripe ingredient and inspires pounds the influence pitch point caking intensity which the control quality all makes, therefore in portal frame construction project construction process, because in each pillar construction inevitably and the lower level pillar existence construction joint, how does leave alone the construction joint, how processes the construction joint, causes the project quality not to receive affects, guaranteed concrete the structure security, appears especially importantly. 1.current portal frame construction pitch point job practice and the flaw. (1) the early time in the general portal frame construction, after pours a pillar, carries on a mold, after the template installment completes only then enters sewer the working procedure to pour the upper formation girder concrete, therefore acts according to constructs the time limit for a project and the person, the material, machine and so on the situation, the new old concrete continues the gap time length not one, when pouring the general pitch point pours together along with the girder concrete, and the pitch point concrete intensity rank carries on the construction according to girder (2) along with the scientific research
