Arc-shaped steel protective clamping groove limiting device
The arc-shaped steel protective clamping groove limiting device comprises an arc-shaped frame, a sling and two limiting blocks, a blocking plate with the two ends open is welded along the outer arc line of the arc-shaped frame, so that a binding track allowing the sling to penetrate is formed between the blocking plate and the outer arc line of the arc-shaped frame, and the two limiting blocks are detachably connected to the sling. The two limiting parts are arranged at the two ends, close to the opening of the plugging plate, of the sling to limit the sling in the binding track; according to the scheme, when binding type hoisting is carried out on the carrying pole beam, the arc-shaped frame is in transition between the sling and the beam bottom plate, damage or extrusion deformation caused by the fact that the sling extrudes the beam bottom plate can be avoided, the limiting blocks are arranged on the two sides of the arc-shaped frame, the situation that when a large-span curve beam body is hoisted, the gravity eccentric sling slides in a binding rail can be prevented, and the construction risk coefficient is greatly reduced; the method has the characteristics of simple construction operation, high safety coefficient and strong practicability.
本发明公开了一种弧形钢制防护卡槽限位装置，包含弧形框架、吊索和两个限位块，沿弧形框架的外弧线焊接有两端开口的封堵板，使得封堵板和弧形框架外弧线间形成允许吊索穿入的捆绑轨道，两个限位块可拆卸连接于吊索上，分别布置于吊索靠近封堵板开口的两端，以形成吊索在捆绑轨道内的限位；该方案在进行扁担梁进行捆绑式吊装时，弧形架在吊索与梁底板间作过渡，可避免吊索挤压梁底板造成损坏或挤压变形，在弧形架两侧设置限位块，可防止在起吊大跨径、曲线梁体重力偏心吊索在捆绑轨道内滑移，大幅度降低施工风险系数；具有施工操作简易、安全系数高和实用性强的特点。
