采用定型组合钢模时,梁柱接头处支模方法是框架结构工程的一大难点,如果施工方法不当,会造成梁柱接头处混凝土“变形”“缩颈”“胀模”等现象。一、接头处支模困难的原因1.沿柱子高度方向不合钢模模数。一般支模是从下向上排模,这样,钢模板不可能正好到达框架梁底或板底,于
When using the combined steel model, the method of supporting the mold at the beam-column joint is a major difficulty in the frame structure engineering. If the construction method is improper, it will cause the phenomenon of “deformation”, “contraction” and “expansion mold” of the concrete at the beam-column joint. First, the reasons for the difficulty in supporting the mold at the joint 1. In accordance with the height of the column does not fit the steel modulus. In general, the mold is lined up from the bottom to the top so that the steel template cannot reach the bottom of the frame beam or the bottom of the frame.
