Description

Connecting device of steel structure node Technical Field The utility model relates to the technical field of steel structures, in particular to a connecting device for steel structure nodes. Background In the field of modern architecture and engineering, steel structures are widely applied to various large-scale building structures, bridge engineering, industrial plants and other projects by virtue of the remarkable advantages of high strength, light dead weight, high construction speed and the like. The steel structure node serves as a key part in a steel structure system and plays important roles in connecting each component, transmitting load and guaranteeing the overall stability of the structure. Chinese patent with publication No. CN220433932U discloses a connecting device for steel structure node, it passes through angle steel one on the stand, angle steel one upper end bolt one, the bolt is through angle steel one, bolt one runs through the stand, bolt one runs through angle steel two, bolt one and nut one threaded connection, can make angle steel one and angle steel two fix on the stand, make things convenient for angle steel one and angle steel two's installation, angle steel one upper end bolt two, bolt two runs through angle steel one, bolt two runs through i-beam one, bolt two and nut two threaded connection, can make angle steel one and i-beam one fixed, it is more convenient to fix. But in actual operation, the I-shaped steel beam is usually installed in a hoisting mode, workers need to constantly adjust the position of the I-shaped steel beam to align bolt holes in the hoisting process, fine adjustment is often needed to be repeatedly carried out in the process, the steel beam is slowly moved through manpower or auxiliary equipment, the whole process is quite tedious, the installation time of the steel beam is greatly increased, and the overall construction progress is influenced. Disclosure of utility model The utility model aims to provide a connecting device for a steel structure node, which effectively solves the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions. The utility model provides a connecting device of steel construction node, includes stand and I-steel beam, and the angle steel is installed down to the both sides surface of stand through first bolt, and the limiting plate is all installed to the both sides of angle steel upper surface down, and the guiding groove has all been seted up to the opposite face of two limiting plates, and the upper end of guiding groove is provided with the opening. The outer surfaces of the two sides of the I-shaped steel beam are provided with positioning pieces which are matched with the guide grooves. The I-shaped steel beam is arranged on the upper surface of the lower angle steel through a second bolt.
