Cast steel joint stress test device

Abstract

The invention discloses a cast steel joint stress test device. The structure of the cast steel joint stress test device comprises a first cast steel joint, a second cast steel joint, a fixed sphere, circular sections, a fixing supporting seat, fixing cylinders, a third cast steel joint, rolling balls, ring blocks, a fourth cast steel joint, protective covers, stress test devices, cast steel innerwalls, grooves, cushion blocks and a reinforcement foot; the circular section is connected with the corresponding fixing cylinder; the fixed cylinder is provided with the corresponding protective cover; the ring block is connected with the corresponding rolling ball through the corresponding cushion block; the cast steel inner wall is connected with the corresponding stress test device; and the fixing supporting seat is connected with the reinforcement foot. According to the cast steel joint stress test device, the stress test devices are adopted, so that the stresses value of the cast steel joints can be accurately and quickly measured; and the rolling balls are arranged in the grooves, so that a rolling effect can be realized, and therefore, the positions of connection holes are changed.The cast steel joint stress test device has the advantages of high safety and structural simplicity. The fixing cylinders are provided with the protective covers, so that the service life of cast steel can be greatly prolonged.

Description

technical field [0001] The invention relates to a stress testing device for cast steel joints, which belongs to the technical field of cast steel. Background technique [0002] The complex space tube truss steel structure has been widely used because of its unique and beautiful shape, short construction period, good ductility, strong plastic deformation ability, light weight, and the ability to increase the space of the building, change the form, and adapt to complex shapes. For large-scale landmark buildings such as exhibition buildings, stadiums, hangars, and waiting halls, the cast steel joints of pipe trusses also avoid large residual stress during multi-member welding, have a large degree of design freedom, and have uniform materials. It is widely used because of its good mechanical performance in different directions and small residual stress. [0003] The existing patent discloses a stress testing device for cast steel joints with the application number of 2010206729...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a stress testing device for cast steel joints to solve the existing problems that the testing speed of cast steel joints is relatively slow and the position of the connecting holes cannot be changed.
