Problems solved by technology
[0003] During the construction loading process, the main structure has uneven settlement. For the steel tube concrete column and the shear wall, due to the uneven settlement of the two, simultaneous construction is likely to cause adverse effects such as cracking and staggered walls at the junction, thus affecting the wall. Therefore, there is an urgent need for a construction method to solve the impact of uneven settlement at the junction of CFST columns and shear walls

The invention discloses a construction method for the joint of a differential settlement lower steel column and a shear wall. The construction method includes the steps that the steel column is installed in placed according to design requirements, the to-be-constructed shear wall is divided into a post construction area close to the steel column and a previous construction area away from the steelcolumn; vertical stress steel bars of the shear wall are installed in the previous construction area; stirrup binding is conducted on the vertical stress steel bars in the previous construction area;film sealing and concrete pouring construction is conducted on the periphery of the previous construction area after stirrup binding is completed; after concrete is solidified and the strength reaches the requirements, a sealing film at the joint of the previous construction area and the post construction area is demounted; and the vertical stress steel bar of the shear wall are installed in thepost construction area. By means of the construction method, the post construction area is reserved at the joint of the shear wall and the steel column, after a body is constructed, concrete is poured, the operation space is large, operation such as chipping and cleaning is facilitated, and the influences that the wall body at the joint is cracked and dislocated are not likely to be caused.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for the junction of a steel column and a shear wall under uneven settlement. Background technique [0002] Shear walls are also called wind-resistant walls, seismic walls, and structural walls. Walls in houses or structures that mainly bear horizontal loads and vertical loads caused by wind loads or earthquakes. Prevents structural shear damage. Walls can be divided into load-bearing walls and shear walls according to their stress characteristics. The former mainly bears vertical loads, such as masonry walls; the latter mainly bears horizontal loads. In the seismic fortification area, the horizontal load is mainly generated by the horizontal earthquake action, so the shear wall is sometimes called the seismic wall. [0003] During the construction loading process, the main structure has uneven settlement. For the steel tube concrete column a...
