Description
Technical Field
The present utility model relates to building support components, and more particularly to a coil rail.
Background
In the building construction process, in order to facilitate construction operation of workers on different parts of a building, personal safety of the workers is ensured to a certain extent, and scaffolds are built at the periphery of the building. Compared with the traditional bowl-buckled scaffold, the bowl-buckled scaffold has the advantages of large bearing capacity, high safety, good stability, high assembly and disassembly speed, wide operation space, neatness and attractiveness, labor cost saving and the like, and is widely applied to various engineering construction processes.
However, in the practical application process, the disc buckle type cross bar is limited by the modulus, and when the engineering structure length does not meet the modulus requirement and is in some special positions, the application of the disc buckle type scaffold is limited, especially when the disc buckle type scaffold is erected at a high-low span position. To break the modulus limitation, crossbars of adjustable length have been developed. The current common practice is to set up the high-low span position as follows: (1) The height of the vertical rods is adjusted through the adjustable base, so that the vertical rod connecting discs on the two sides of the high-low span are positioned on the same horizontal plane and then connected through the cross rod; (2) The common steel pipe fastener is used for connecting the high-low span side frames, and the high-low span side frames extend outwards for more than two spans. Both of these methods have the following disadvantages: the construction cost and the workload of operators are increased.
If the patent with the bulletin number of CN 211923495U is granted, a disc buckle type non-modulus horizontal adjusting rod is disclosed, the horizontal rod comprises a loop bar with one end fixedly connected with a connector, and a threaded rod which is in threaded connection with one end of the loop bar far away from the connector and is coaxial with the loop bar, and one end of the threaded rod far away from the loop bar is connected with the connector. The length of the threaded rod in the loop bar is changed, so that the whole length of the horizontal rod is changed, the limit of the modulus is avoided, and the distance between two different vertical rods in different construction environments is better adapted. But cannot be applied to high and low span positions.
