Problems solved by technology
[0005] The present invention can solve the problem that the existing steel structure fasteners have poor use effect and inconvenient adjustment when in use, usually cannot be effectively adjusted according to the distance between the steel structures, which affects the assembly accuracy of the bridge steel structure, and at the same time When the existing steel structure fasteners are used, they cannot connect and fix support rods with different diameters, and the support effect is poor and the connection is unstable, resulting in poor support stability of the steel structure and affecting the overall strength of the bridge steel structure and service life issues

The invention relates to a bridge steel structure connecting fastener which comprises a bottom plate, a fastening device and a connecting frame. The bottom plate is installed at an upper end of a steel structure through screws, the fastening device is installed in the middle of the upper end of the bottom plate, the connecting frame is installed at the upper end of the fastening device, and the upper end of the connecting frame is connected with the steel structure through the screws. The fastener can solve problems that when an existing steel structure fastener is used, a use effect is poor and adjustment is inconvenient; generally, effective adjustment can not be effectively carried out according to the distance between steel structures and assembling precision of a bridge steel structure is affected; and meanwhile, when the existing steel structure fastener is used, supporting rods with different diameters cannot be connected and fixed, a supporting effect is poor, connection is notstable, the supporting stability of a steel structure is poor, and the overall strength and the service life of the bridge steel structure are affected.
Description
technical field [0001] The invention relates to the field of steel structures, in particular to a bridge steel structure connection fastener. Background technique [0002] The main design concept of the steel structure bridge is to assemble the least types of unit components into a prefabricated steel bridge capable of carrying various loads and different spans, and only need to be transported by ordinary medium-sized trucks. In special cases, it can be built entirely by manpower. Therefore, steel structure bridges have been widely used in urban infrastructure construction. [0003] At present, when the existing bridge steel structure is connected and fixed, there are usually the following defects: 1. When the existing steel structure fasteners are used, the use effect is poor, the adjustment is inconvenient, and it is usually not effective according to the steel structure. Effectively adjust the spacing between the bridge steel structures, which affects the assembly accura...
