Simple fastener for cantilever scaffold in constructional engineering

The invention discloses a simple fastener for a cantilever scaffold in constructional engineering. The fastener comprises a U-shaped rod, a pressing plate and nuts, wherein the U-shaped rod is composed of a connecting rod and two threaded rods, the two threaded rods are arranged in parallel, and both ends of the connecting rod are fixedly connected with the same ends of the two threaded rods respectively; a pair of first mounting ports are symmetrically formed in the pressing plate, the two first mounting ports are respectively located in both ends of the pressing plate, and the first mounting ports are used for allowing the threaded rods to penetrate through; and the number of the nuts is at least two, the nuts sleeve the threaded rods in a threaded mode, and the outer diameter of the nuts is larger than the caliber of the first mounting ports. At least two objects which need to be connected are inserted into the space defined by the pressing plate and the U-shaped rod in a penetrating mode, then the pressing plate and the U-shaped rod are matched to clamp the objects, finally, the two objects cannot be separated, and the effect of fastening connection is achieved. Compared with steel wire winding and binding, the fastener has the advantage of convenience in disassembly and assembly.
