Sleeve type chimney transverse shake stopping device
The invention discloses a transverse shake stopping device for a sleeve type chimney, belongs to the field of sleeve type chimneys, and solves the problem that an inner cylinder of the sleeve type chimney can generate large displacement under the action of a horizontal load. A bracket is arranged on the inner wall of an outer cylinder of the sleeve type chimney, a plurality of embedded parts are arranged in the bracket, a steel beam is connected between every two adjacent embedded parts, a ring beam is arranged on the outer wall of an inner cylinder of the sleeve type chimney, and a supporting mechanism is arranged between each steel beam and the corresponding ring beam. The supporting mechanism is installed between the inner cylinder and the outer cylinder of the sleeve type chimney, transverse displacement of the inner cylinder caused by horizontal loads such as wind loads and horizontal earthquakes can be effectively limited, and shaking of the inner cylinder is limited. Shaking of the inner cylinder is transmitted to the supports through the shake stopping rods, displacement is restrained, the supports generate acting force on the steel beams firstly, the acting force is transmitted to the brackets through deformation of the steel beams, and the impact effect on the outer cylinder is relieved; a circle of ring beam is arranged on the outer wall of the inner cylinder, the effect of reinforcing the inner cylinder is achieved, and stress acting on the inner cylinder is reduced.
本发明公开了一种套筒式烟囱横向止晃装置，属于套筒式烟囱领域，解决了套筒式烟囱的内筒在水平荷载作用下会产生较大位移的问题。本发明在套筒式烟囱的外筒内壁设有牛腿，牛腿内设有多个预埋件，相邻的预埋件之间连接有钢梁，在套筒式烟囱的内筒外壁设有环梁，在钢梁与环梁之间设有支撑机构。本发明在套筒式烟囱的内筒和外筒之间安装支撑机构，能有效限制风荷载、水平地震等水平荷载作用下带来的内筒横向位移，限制内筒晃动。内筒的晃动通过止晃杆传递到支座，位移受到约束，支座先对钢梁产生作用力，通过钢梁的变形传递到牛腿，减轻对外筒的冲击作用；在内筒外壁设置一圈环梁，起到加固内筒的作用，减小作用在内筒上的应力。
