Embodiment 1

[0036] (1) Multiple sets of anchor bolts 9 are pre-embedded along the horizontal and vertical directions according to the set position on the cap foundation. Each set of anchor bolts 9 is composed of multiple anchor bolts. Adjusting nut 7;

[0037] (2) Use a tower crane to hoist the shaped steel column and make the base plate 5 of the shaped steel column supported on the adjusting nuts 7 of a set of anchor bolts 9 correspondingly arranged, then insert a backing plate 10 on each anchor bolt and Screw in a fastening nut 6 and a stop nut 8 in turn, and then adjust the elevation of the adjustment nuts on each group of anchor bolts so that the elevation error of all backing plates is controlled within 1.0 mm. A column foot rib 11 is fixed between the bottom and the column foot bottom plate 5, and a column cap shaped steel mold 1 is connected with a bolt on the column head of the shaped steel column. A steel beam installation joint 2 is installed in the horizontal direction;

Abstract

The invention discloses a method for constructing a steel column and column head sizing steel model of profile steel. The method comprises the following steps: pre-embedding multiple groups of foundation bolts into a stand foundation, and screwing an adjusting nut onto each foundation bolt; hoisting a profile steel column, enabling a column base plate of the profile steel column to be supported onthe adjusting nuts of a group of foundation bolts which are correspondingly arranged, inserting one base plate on each foundation bolt, sequentially screwing fastening nuts and non-stop nuts, and then adjusting the scale height of the adjusting nuts on each group of foundation bolts; correcting the size of the profile steel column arranged at the lowest layer; carrying out secondary grouting on the bottom part of the column base plate; then sequentially connecting steel main beams or steel secondary beams, binding profile steel column reinforcing steel bars, and installing a column mold of the layer; fixing the profile steel column in the upper layer to each profile steel column; then sequentially connecting the steel main beams or the steel secondary beams, binding the profile steel column reinforcing steel bars, and installing the column mold of the layer; finally pouring concrete in the column mold. By adopting the method disclosed by the invention, the bearing capacity, the rigidity, the fire resistance and the seismic resistance of a structure are greatly increased.

Description

technical field [0001] The invention relates to a stylized method for a column head, in particular to a construction method for a shaped steel column and a stylized steel mold for a column head. Background technique [0002] With the development of my country's economy and the advancement of science and technology, the height of industrial and civil buildings is increasing, the number of floors is increasing, and the column network is becoming denser. In order to meet the requirements of bearing capacity, the cross-section of the columns at the bottom of the structure The size will inevitably increase, which will not only affect the use and function of the structure, but also form short columns that are not conducive to earthquake resistance. As a new type of structural system, the steel-concrete composite structure utilizes the principle of synergy between steel, steel bars and concrete to greatly improve the bearing capacity, stiffness, fire resistance, and seismic performa...
