Description

Technical Field

[0001] The present invention relates to a beam-column supporting structure, in particular to a full-bolt high-load beam-column supporting member. Background Art

[0002] The temperature difference between day and night on the Qinghai-Tibet Plateau is large, and many places are in a low-temperature state all year round. The biggest problem with building on permafrost is the complex terrain. In most areas, the roads are rugged, with many sharp turns and dense tunnels and culverts. Road damage caused by mudslides and landslides occurs frequently, which has a huge impact on the transportation of construction materials and equipment. Large machinery and construction equipment such as cranes and pile drivers cannot be transported, and road damage and bad weather also make transportation time uncontrollable. Building materials also need to be easy to transport, easy to install, and have high strength and earthquake resistance requirements. Therefore, in most cases, the concrete pouring method commonly used in plains cannot be used. The current research direction is to use steel structures as the main body of the building, using ceramic thin plates, high-strength alloy aluminum plates and wood materials as the top, walls and floors. Given the soft soil and the melting of the permafrost surface, the beams, columns and supports of the main structure need to meet the requirements of earthquake resistance and high strength. Commercially available steel structures cannot meet these requirements. Summary of the Invention
