Problems solved by technology

The shortcoming that this fastening device exists is: 1, adopt the method for buckle to fasten the steel pipe, but the fixing assembly at the buckle is relatively weak, when bearing greater pressure, the buckle is extremely easy to break and trip, causing irreparable 2. The number of components of the fastening device is large, the installation and disassembly steps are many and cumbersome, the operation efficiency is very low, and the materials used in production are large, and the manufacturing cost is high, which is not conducive to the formation of large-scale production requirements

Abstract

The invention belongs to the technical field of fastening devices for steel pipes in building construction, and relates to a tensioning type fastening device for orthographically-overlapped steel pipe levers. The tensioning type fastening device comprises a clamp and a tensioning mechanism, and the clamp is connected with the tensioning mechanism. The tensioning type fastening device is characterized in that the tensioning mechanism is composed of a short tensioning plate, a long tensioning plate, a connecting plate, a pull buckle and hinge pieces, first connecting holes are formed in one side edge of the short tensioning plate, first connecting seats are arranged on the other side edge of the short tensioning plate, and first hinge holes are formed in the first connecting seats; second connecting holes are formed in one side edge of the long tensioning plate, second connecting seats are arranged on the other side edge of the long tensioning plate, and second hinge holes are formed in the second connecting seats; pull buckle feet are arranged on the two sides of the pull buckle, and third hinge holes and fourth hinge holes are formed in the pull buckle feet; a first hinge column and a second hinge column are arranged at the two ends of the connecting plate, the first hinge column is arranged in the first hinge holes in a pivotal mode, the second hinge column is arranged in the third hinge holes in a pivotal mode, and the second hinge holes are connected with the fourth hinge holes through the hinge pieces. Mounting and dismounting are convenient, work efficiency is improved, fixing is firm, and use is safe. Manufacturing is convenient, and cost is low.

Description

technical field [0001] The invention belongs to the technical field of fastening devices between steel pipes in building construction, and in particular relates to an orthogonally stacked steel pipe lever tensioning type fastening device. Background technique [0002] At present, steel pipe protection platforms, operating platforms, formwork steel corrugations, ordinary protective railings and scaffolding on construction sites all need fasteners to fix steel pipe nodes when they are in use, which can improve the safety of facilities to a certain extent. Today Most of the fasteners used for fixing steel pipes use accessories such as screws and nuts to fix the steel pipes. This fixing method is not only time-consuming and labor-intensive during installation and disassembly, but also the nuts are easy to fall off during vibration, and there are problems that cannot be ignored. Potential safety hazards may cause collapse accidents of the steel pipe structure. [0003] In the pr...
