A bim-based treatment method for steel bars at cross-steel column-beam joints

Abstract

The invention discloses a method for treating reinforcing steel bars at cross-shaped steel reinforced column and beam joints on the basis of BIM (building information modeling). The method has the advantages that parameterized BIM models are built, the lengths of supporting plates of cross-shaped steel reinforced columns are constrained by the BIM in advance, accordingly, the supporting plates can be accurately positioned, and a condition that main reinforcing steel bars are collided with the supporting plates can be prevented; the setting-out of longitudinal beam reinforcing steel bars at column and beam intersections is simulated by the aid of the BIM, processes for treating each beam reinforcing steel bar are determined, beams with the weld lengths meeting requirements are welded on the supporting plates and connecting plates, the reinforcing steel bars with large diameters penetrate holes of web plates, and the beam reinforcing steel bars can be directly set out by site staffs according to the models; the beams, the columns and steel ribs can be simulated by the aid of the BIM in advance, disclosure can be carried out on teams and groups, the reinforcing steel bars can be directly placed and welded according to the models during site construction, accordingly, the work efficiency can be improved, wastage of the reinforcing steel bars can be reduced, the construction progress can be accelerated in sites, and the quality of the steel reinforced columns can be improved.

Description

technical field [0001] The invention relates to the field of steel bar deepening design, in particular to a BIM-based method for processing steel bars at joints of cross steel bone columns and beams. Background technique [0002] With the rapid development of urban construction, the building density in the urban area is increasing day by day, and the city's demand for super high-rise buildings is also increasing. The use of steel reinforced concrete columns can reduce the size of the column section, save the amount of concrete and steel bars, and at the same time increase the usable area of ​​the building and beautify the shape. Therefore, steel columns are more and more widely used in high-rise buildings. As a type of steel-concrete composite structure, although the cross-steel-reinforced column has been used in domestic projects, due to the immature construction technology, it will inevitably cause delays in the construction period, difficulty in ensuring construction qual...

Problems solved by technology

[0006] (2) If there are many beams intersecting the columns, some beam reinforcements need to be welded to the connecting plates between the webs, and some of them directly pass through the reserved holes at the webs. Passing through the hole or welding with the connecting plate can only make a second hole at the web, which affects the quality of the project

[0007] (3) When the height of the beam is small, and the lower reinforcement of the beam cannot pass through the web or be welded to the connecting plate, the beam reinforcement can only use curved anchors. If the connecting plates are set in advance, the length of the straight anchor section of the curved anchor It is possible to exceed the spacing of the connecting plates, and the beam reinforcement cannot extend into the stiff column reinforcement
