Description
Technical field
This utility model relates to Construction Formwork & Scaffold Technology field, a kind of scaffold butt joint fastener being easily installed.
Background technology
When installation foot hand cradle, two steel pipe docking need to use clasp, existing to clasp, mainly it is made up of enclosing cover and the axis of guide, enclosing cover is generally formed by two semicircle cover plates are hinged, it is generally required to enclosing cover is opened during use, it is directed to pivot pin and enters in the middle of steel pipe, the most again enclosing cover is detained, fastening screw is used to be clamped in the middle of fastener by steel pipe, the structure of existing fastener makes workman's operating time in work progress long, installation difficulty is big, and the hinge between two cover plates deforms the most under external force, cause to open enclosing cover when dismounting is to clasp, make to dismantle clasp from steel pipe.
Utility model content
The purpose of this utility model is to provide a kind of scaffold butt joint fastener being easily installed, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of scaffold butt joint fastener being easily installed, including upper cover plate and lower cover, connect between described upper cover plate and lower cover and have bolt, the lower end of described bolt is threaded nut, and the outer wall laminating of nut and lower cover, the upper end of described bolt is fixedly connected with connecting rod, described connecting rod is plugged on the inner chamber of connecting hole, described connecting hole is opened in the outer wall of cam fastener, the outer wall of described cam fastener is fixedly connected with depression bar, it is provided with the axis of guide between described upper cover plate and lower cover, the outer wall of the described axis of guide has through hole, described bolt-through through hole, the two ends, left and right of the described axis of guide are respectively sleeved on the second connecting tube and the first connecting tube.
Preferably, the described axis of guide is I-steel, and the upper surface of the axis of guide and lower surface are arc.
Preferably, between lower surface and the upper cover plate of described cam fastener, it is provided with rubber blanket, and arc groove is left on the surface of rubber blanket.
Compared with prior art, the beneficial effects of the utility model are: the scaffold butt joint fastener being originally easily installed, cover plate is divided into upper and lower two parts, it is bolted between upper cover plate and lower cover, bolt upper end is provided with cam fastener, install this to during to clasp, two connecting tubes are socketed in the outer wall of the axis of guide, pressure depression bar can complete to install simultaneously, installation process simple and fast, it is bolted between two cover plates simultaneously, contrast existing hinged mode, intensity is higher, and will not cause opening cover plate because of hinge deformation, service life is long.
