The invention discloses a special lifting tool for a steel structure, and relates to the field of steel structure hoists. The special lifting tool for the steel structure comprises a bottom plate, theouter edge of the top surface of the bottom plate is actively connected with a transmission mechanism, the transmission mechanism actively sleeves an extrusion mechanism in the middle, the top end ofthe extrusion mechanism is fixedly connected with a roof plate, the top of the roof plate is fixedly connected with a control sleeve, and threads are formed in the inner wall of the control sleeve. The special lifting tool for the steel structure realizes the connection and extrusion between the top surface and the bottom surface of a steel through hole through the transmission mechanism matchedwith a connecting plate, and the lifting effect is realized; the flat transmission mechanism is effective for the uniform gravity bearing of steel, the lifting effect is improved, through the extrusion mechanism, the contact area of the steel surface is increased by using the extrusion deformation of an airbag piece, the stress situation on the steel surface per unit area is reduced; and at the same time, the damage to steel surface coating is avoided, and the lifting effect of a steel workpiece is improved. The problem of the damage to the steel surface coating by the lifting tool is solved.

    本发明公开了一种钢结构专用吊具,包括底板,所述底板顶面的外沿活动连接有传动机构,所述传动机构的中部活动套接有挤压机构,所述挤压机构的顶端固定连接有顶板,所述顶板的顶部固定连接有控制套,所述控制套内壁的开设有内螺纹。本发明涉及钢结构吊具领域。该钢结构专用吊具通过传动机构配合衔接板实现了对钢材通孔顶面和底面的之间衔接与挤压,实现了吊装效果,传动机构平展对钢材本身重力承载均匀有效,提升了吊装效果,通过挤压机构,利用气囊件受挤压形变增加了与钢材表面的接触面积,减轻了单位面积的受力情况,同时避免了对钢材表面涂层的损伤,提升了钢材工件的吊装效果。这解决了吊具对钢材表面涂层损伤的问题。
