CN205153150U 一种框架梁柱节点加固结构 失效 - 放弃

一种框架梁柱节点加固结构
摘要：
本实用新型公开了一种框架梁柱节点加固结构，包括原框架柱、框架梁、钢套管以及钢筋笼，所述钢筋笼包括插筋、内圈环梁环筋以及外圈环梁环筋，框架梁连接到原框架柱上，内圈环梁环筋与外圈环梁环筋分别穿过框架梁围绕在原框架梁柱节点的外侧，外圈环梁环筋位于内圈环梁环筋外侧，插筋竖直设置并且与内圈环梁环筋连接，所述钢套管包围在原框架柱外，还包括填充在钢套管与原框架柱之间以及将钢筋笼填埋起来的加固混凝土层。本实用新型的加固方式利用了内圈环梁环筋以及外圈环梁环筋对框架梁柱节点核心区的约束作用，极大的提高了框架梁柱节点的抗剪承载力和刚度，从而改善了框架梁柱节点的抗震性能。
摘要（英）：

The utility model discloses a frame beam column node reinforced structure, including former frame post, frame roof beam, steel casing pipe and steel reinforcement cage, the steel reinforcement cage includes joint bar, inner circle ring beam ring muscle and outer lane ring beam ring muscle, and on the frame roof beam was connected to former frame post, inner circle ring beam ring muscle and outer lane ring beam ring muscle passed frame roof beam around the outside at former frame beam column node respectively, and outer lane ring beam ring muscle is located the inner circle ring beam ring muscle outside, and the vertical setting of joint bar is and be connected with inner circle ring beam ring muscle, the steel casing pipe surrounds outside former frame post, still including the reinforcement concrete layer who fills between steel casing pipe and former frame post and get up the steel reinforcement cage landfill. The utility model discloses a reinforcement mode has utilized inner circle ring beam ring muscle and outer lane ring beam ring muscle to the constraining effect of frame beam column node core space, very big improvement the shear bearing capacity and the rigidity of frame beam column node to the anti -seismic performance of frame beam column node has been improved.
