Fabricated steel structure beam-column joint provided with weakening type energy dissipater
The invention provides an assembly type steel structure beam-column joint provided with a weakening type energy dissipater. The assembly type steel structure beam-column joint comprises a column body and a beam body, and one end of the beam body is fixed between two positioning clamping plates through a pin shaft; the pin shaft is inserted into the sleeve, the sleeve is perpendicular to the beam body, and sleeve stiffening ribs are distributed on the surface of the beam body; weakening type energy dissipaters are respectively arranged on the upper and lower end faces of the beam body close to the end head of the column body; each energy dissipater comprises an energy dissipation plate, and the energy dissipation plate is connected with the corresponding end face of the beam body through two connecting positions; at one connecting position, a buckling-restrained cover plate is attached to the surface of the energy consumption plate, a rubber pad is padded between the energy consumption plate at the corresponding position and the end face of the beam body, and a long round hole is formed in the energy consumption plate. The buckling-restrained cover plate, the energy consumption plate and the rubber pad are fixed through fasteners and are connected to the corresponding end faces of the beam body at the connecting positions; the energy consumption plate is fixed on the corresponding end face of the beam body at the connecting position through another fastener; the carbon fiber cloth stretches across the cover plate; the energy consumption plate is further provided with two connecting plates perpendicular to the plate face, and the two connecting plates are connected and positioned to one side ends of the two positioning clamping plates respectively.
本发明提供一种设置削弱型耗能器的装配式钢结构梁柱节点，包括柱体和梁体，梁体一端经销轴固定于两定位夹板间；销轴插于套管内，套管垂直于梁体，梁体表面布设套管加劲肋；梁体靠近柱体端头位的上下端面分设一削弱型耗能器；每个耗能器包括一耗能板，耗能板经两连接位与梁体对应端面连接；于其一连接位，耗能板表面贴合有防屈曲盖板，相应位的耗能板与梁体端面间垫衬橡胶垫，耗能板上开设长圆孔；经紧固件固定，防屈曲盖板、耗能板与橡胶垫于该连接位连接于梁体相应端面；经另一紧固件固定，耗能板于该连接位固定于梁体相应端面；还有横跨盖板的碳纤维布；耗能板还设有与板面垂直的两连接板，两连接板分别于两定位夹板的其中一侧端连接定位。
