Description
Technical Field
The invention relates to the technical field of building industry, in particular to a novel connecting piece of a horizontal rod of a walkway of a disc-type scaffold operating layer and a connecting method thereof.
Background
At present, the construction industry more and more attaches importance to the standardization and the regularization of construction safety facilities, and the disk-buckle type scaffold is gradually popularized and adopted as the requirement of issuing bulletins in various provinces and cities. The coil buckle type scaffold has the advantages of firm connection, stable structure, safety, reliability and the like, and compared with the traditional steel pipe fastener scaffold, the coil buckle type scaffold is quick to take and detach, and the installation effect is safer and more attractive. The operation layer of the coil-buckled scaffold is usually laid by steel scaffold boards, hooks are welded at two ends of each steel scaffold board, the hooks of the steel scaffold boards are directly buckled on the horizontal rods during installation, and the hooks are in a locked state.
The steel scaffold board has the characteristics of high strength, corrosion resistance, difficult deformation, long service life and the like, and because the distance between the disc buckle scaffold is the standard sizing size, the steel scaffold board adopts the corresponding sizing size and is matched with the disc buckle scaffold for use, the sizing and standardization requirements of the safety protection of the disc buckle scaffold can be effectively met, and the steel scaffold board is applied to the disc buckle scaffold more and more widely. However, the steel scaffold plate has a large self weight after being welded with the reinforcing ribs, the self weight of each square is about 0.35KN, if the steel scaffold plate is fully paved on each operating layer, the whole self weight of the disc buckle scaffold is large, the price of the steel scaffold plate is high, and the whole cost of one-time investment is high.
At present conventional steel pipe fastener formula scaffold frame still adopts the steel basketry piece as the scaffold board in a large number, and the dead weight of steel basketry piece scaffold board is light, and every square dead weight is about 0.1KN ~ 0.15KN, and the antiskid is wear-resisting, and use cost is low, compares in the gradual use widely of steel scaffold board, and steel basketry piece scaffold board still obtains extensive application on ordinary steel pipe fastener formula outer scaffold frame. The common steel pipe fastener type scaffold is characterized in that longitudinal horizontal rods are fixed on transverse horizontal rods by cross fasteners and are arranged at equal intervals, at least 4 longitudinal horizontal rods are arranged on each conventional operating layer, each longitudinal horizontal rod is on the same plane, and steel basketry pieces are fixed on the longitudinal horizontal rods by galvanized steel wires and can keep the surfaces of the steel basketry pieces smooth.
However, the steel basketry sheet scaffold is not widely applied to the disc buckle type external scaffold, and the main reason is that the disc buckle scaffold is connected by adopting a buckle head and a plug sheet, after the erection is completed, the inner and outer longitudinal horizontal rods and the transverse horizontal rod are on the same plane, if the middle walkway adopts two common steel pipes and a transverse horizontal rod cross fastener to be connected, the height difference exists between the inner and outer longitudinal horizontal rods and the middle two longitudinal steel pipes, and when the steel basketry sheet is laid and fixed, the steel basketry sheet 1 is in an upward curved arch shape, as shown in fig. 1, the operation layer is uneven, and the safe use function is influenced.
