The connection claw jig is a common point support device for glass curtain wall, which meets the requirements of high permeability of glass curtain wall. It is widely used in the structural form of point support glass curtain wall with large grid and large plate. With the continuous development of curtain wall technology, the requirements for the mechanical properties of the connecting claw jig are becoming higher and higher. It is difficult to ensure the best mechanical properties of the product under the traditional design methods. In order to study the optimal structure design method of the claw, based on the multi-objective optimization theory, this paper takes the quality, the maximum equivalent stress, the minimum safety factor and the maximum deformation of the claw as the optimization objectives, carries out the structural optimization design of the claw, analyzes the sensitivity of the main structural parameters of the claw, and studies the influence of the design variables within the optimization interval on the maximum equivalent stress the results show that the mechanical properties are improved and the quality of the jig is reduced by 9.6%.
