Beam column connection node

Abstract

The invention provides a beam column connection node, including a first connecting plate, a second connecting plate, a hinge pin and at least two energy dissipating parts, the first connecting plate is connected with a side face of a prefabricated column, the second connecting plate is connected with an end face of a prefabricated beam, the first connecting plate and the second connecting plate are connected through the hinge pin, the two sides of the first connecting plate are respectively provided with the energy dissipating parts, the two ends of the energy dissipating parts are respectively hinged to the prefabricated column and the prefabricated beam, the two ends of the energy dissipation parts are provided with connecting columns, connecting seats are respectively arranged on the prefabricated column and the prefabricated beam, the connecting seats are provided with through holes penetrating through two ends thereof, side walls of the connecting seats are provided with connecting ports, the connecting ports extend along the axial directions of the connecting seats and communicate with the through holes, the connecting columns are inserted into the through holes, and maintainelasticity during an earthquake and serious structural loss is reduced, multi-level fortification is realized, connection is convenient, quick and efficient mounting on a construction site can be realized, and post-earthquake maintenance is facilitated.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a connection node of beams and columns. Background technique [0002] As my country enters a critical stage of economic structural transformation and upgrading, vigorously developing prefabricated buildings has been determined as an important measure to promote supply-side structural reform and new urbanization development. As a high-performance building structure with environmental protection and high material strength, the prefabricated steel structure building is a kind of building structure commonly used in high-rise buildings in developed countries in the world. The prefabricated steel frame structure is the most widely used in prefabricated steel structure buildings. a structural system. However, previous earthquake damages have shown that whether the prefabricated steel frame structure has sufficient bending resistance is very important to protect the safety of peo...

Problems solved by technology

However, the common disadvantages are high processing and construction precision requirements, cumbersome on-site construction procedures, and high post-earthquake reinforcement costs.

For example, the welding technical scheme requires a lot of welding work on site, which is not only labor-intensive and time-consuming, but also requires high construction. If the quality of the weld seam is not high, it will easily become the weakest point of the entire steel frame structure. A large number of welds were damaged in the Ridge Earthquake. Although the pure bolt connection does not require welding on site, it requires extremely high machining and construction precision for steel components. Dislocation of the bolt holes often occurs at the construction site, and the bolts cannot be screwed properly. The above phenomenon caused the workers to enlarge the bolt holes on the construction site and forcibly screw in the bolts, which not only increased the construction process, but also left a great potential safety hazard
