Cross construction method for complex V-shaped stiff columns and irregular ring beams of large stadium

Abstract

The invention relates to the field of construction of large public stadiums, and particularly relates to a cross construction method for complex V-shaped stiff columns and irregular ring beams of a large stadium. The method comprises the steps of 1, BIM modeling; 2, steel structure hoisting; 3, steel bar binding engineering; 4, formwork erecting; 5, concrete pouring; and 6, concrete curing. According to the principle of the construction method, due to the fact that adjacent V-shaped columns have a corner of a certain angle, bottom projections of the V-shaped columns are staggered and overlapped. According to the method, coordinate points are extracted through the BIM technology, on-site corner point positioning is conducted through a total station, and then V-shaped column bottom edge lines are popped up according to positioning points for construction. The construction method for complex cross of the V-shaped super-complex stiff columns and the irregular ring beams of the stadium is achieved in a focused mode, flexibility is achieved, and the concept of sustainable development is met.

Description

technical field [0001] The invention relates to the field of construction of large-scale public venues, in particular to a cross construction method of complex V-shaped rigid columns and irregular ring beams of large-scale venues. Background technique [0002] For large-scale public venues, such as stadiums, there are often reinforced concrete stiff columns with specially designed structures, and these stiff columns are often integrated with ring beams. [0003] For this structure, there are currently several approximate working methods: [0004] 1. Two-way inclined V-shaped column construction method, the column body is pre-positioned through the tire frame, and then the V-shaped column is lifted by the tower crane using the hinged connection at the bottom of the V-shaped column, so that the bottom chord of the inverted triangular truss at the top of the V-shaped column is accurate butt. [0005] 2. The V-shaped stiff column space positioning construction method, after th...

Problems solved by technology

[0008] However, there are some defects in the above construction methods. For example, when the V-shaped stiff column structure is very complex and the ring beam is an irregular ring beam, the binding density of steel bars at the joints will be very dense. In this case, the above four construction methods None of the methods can be completed efficiently and with high quality
