Steel structure honeycomb beam is a kind of steel component, which makes full use of the force characteristics. It has the advantages of light weight, high bearing capacity and economic beauty. It can bring remarkable economic benefits in practical engineering application. Generally, honeycomb beams are made of H-section steel or I-section steel by staggered phase welding after cutting. Compared with real web beams, they can save about 25-30% steel and reduce the total cost by about 15%. They are easier to make than composite trusses and have good anticorrosion performance. They can also make full use of building space and pierce various pipelines and wires. They are often used in some cases where the load is not too heavy. Static structures, such as frame columns and beams, purlins, platform beams and steel beams of steel-reinforced concrete composite structures.
Structural characteristics of honeycomb beams
Honeycomb beam is a new type of beam formed by re-welding combination after cutting H-beam webs according to certain broken lines. After cutting, the position can be changed by shifting staggered or turning. In order to keep the end of the beam flat, redundant parts can be removed or welded steel plate can be repaired.
Selection of Cutting Method
The traditional manual lofting, drawing lines and cutting blanking methods have low efficiency, poor cutting quality and large size deviation, which make it difficult to meet the technological requirements. Honeycomb beams are made of rolled H-beam. The main processes are web folded wire cutting and butt welding. CNC multi-head automatic cutting is adopted in web folding wire cutting. The dimension precision of folding wire cutting is good, the edges of honeycomb holes are neat and clean, laying out and marking are omitted, and multiple cutting nozzles can be cut at the same time. The efficiency is more than 10 times that of manual cutting.
