The invention discloses a connecting fastener. The connecting fastener comprises a clamp ring consisting of two semicircular steel profiles, wherein one sides of the clamp ring are connected through a turnover shaft, and the other sides of the clamp ring are provided semicircular arc-shaped bulges in which fixing holes for locking an upright are formed; cleaning holes are formed in the sides of the clamp ring and are in arc shapes, locating blocks which play a role in limiting are arranged inside the cleaning holes, and the surfaces of the locating blocks are provided with rubber cushions for improving the rubbing effect. The upright can be located conveniently, and the installation of a scaffold can be completed quickly; furthermore, the cleaning holes are formed in the side walls of the clamp ring, a person can observe the condition of a connecting piece for fastening a buckled piece, and the rusting or corroding condition can be processed in time, therefore the potential safety hazard can be prevented; in addition, the connecting fastener is excellent in expandable performance and novel in design, thereby being extensive in market promotion prospect.
Description
technical field [0001] The invention relates to a supporting frame of an article, in particular to a connecting fastener. Background technique [0002] Scaffolding refers to the various supports set up on the construction site for workers to operate and solve vertical and horizontal transportation. The generic term on building circle, refers to building site be used in the higher place that cannot directly construct of exterior wall, interior decoration or floor height. It is mainly for construction workers to work up and down or to maintain peripheral safety nets and to install components at high altitudes. Some projects also use scaffolding as a template, and it is also widely used in advertising, municipal administration, traffic roads and bridges, mines and other departments. For a long time, due to the relatively backward state of the erection tool itself and its construction technology and use safety management, the incidence of accidents has been relatively high. ...
