Problems solved by technology
[0003] When the podium is a glass curtain wall keel system, it is often constructed with a steel rib structure system. During the design, engineers found that when manufacturing a keel system with a steel rib plate height of more than 10 meters, in the traditional design scheme, 12mm thick and 20mm thick steel plates are often used for welding. However, in this process, due to the long length of the weld, the steel ribs are easy to deform during the welding process, and the processing cycle is long and the cost is high. It is often difficult to achieve architects. requirements

Embodiment Construction
[0030] The podium involved in this embodiment has 2 to 5 layers of glass curtain wall keel system with 80x400 steel rib plate structure system, and the height of the steel rib plate is 15 meters. According to the original design plan, 12mm thick and 20mm thick steel plates are welded, and the weld seam is long , the steel ribs are easily deformed during welding, which cannot meet the requirements of the architect. Therefore, the welding process of the steel ribs is the problem to be solved in this project.
[0031] Such as figure 1 Shown, adopt finished steel square pipe 100 and channel steel 200 butt welding in the embodiment;
[0032] Among them, the specification of the finished steel square tube is 12mm thick and 80x380mm;
[0033] The specification of channel steel is 8# channel steel.
[0034] Such as figure 2 As shown, the processing length is 15 meters, and the length of the welding seam is two, and it is realized by segmental welding, that is, there is a gap of 10...

The invention relates to a steel rib plate of a podium building. The steel rib plate is characterized by comprising a steel pipe and profile steel. One end of the steel pipe is fixed with the profile steel. Two weld joints are arranged on the welding face of the steel pipe and the profile steel, and at least one gap is evenly arranged on each weld joint. The steel rib plate has the advantages that the steel rib plate which can be used as the keel system of the podium building is manufactured by welding the profile steel and the steel pipe in a combined manner, the two weld joints are welded through sequence welding, welding deformation can be controlled easily, and fast machining and low machining cost are achieved.
Description
technical field [0001] The invention relates to the field of engineering construction, in particular to a podium steel rib plate and a processing method thereof. Background technique [0002] Most of them are used for shopping malls, offices in open spaces, and some well-established high-rise buildings. From the facade, the whole building is in a "convex" shape, and the lower part with an area larger than the standard floor is the podium. From a structural point of view, most buildings with podiums have basements, the podiums are frame shear walls or frame structures, and the main body of the building is mostly shear walls or hybrid structures. [0003] When the podium is a glass curtain wall keel system, it is often constructed with a steel rib structure system. During the design, engineers found that when manufacturing a keel system with a steel rib plate height of more than 10 meters, in the traditional design scheme, 12mm thick and 20mm thick steel plates are often used...
