Hongxiang Ringlock Straight Lock is a wedge-shaped lock specifically designed for horizontal bars. It is a single piece of forged steel, without any splicing or separate small parts. The overall structure consists of three main parts: the lock head wedge, the limiting shoulder, and the striking end. It is specifically designed to match the four small holes inside the eight-hole disc on the vertical bar, and is also compatible with a dedicated angled lock for the larger holes on the diagonal bar. The two types are differentiated in size and wedge angle, allowing for the separate use of horizontal and diagonal bar accessories from a hardware perspective. The lock head's bevel is CNC milled to create a standard self-locking slope. The shoulder limiting design prevents the straight lock from fully sinking into the hole, avoiding excessive penetration and scratching the vertical bar wall.
The widened striking platform at the end allows for even force application with a small hammer, preventing chipping or cracking of the impact surface. The thickness of the straight lock wedge strictly adheres to the lower limit of the national standard, ensuring sufficient cross-sectional area to fully bear the horizontal tension and lateral impact forces transmitted by the crossbars. It is the core pressure-bearing component for stabilizing the disc-lock horizontal truss.
Ringlock Straight Lock Product Features: Mechanical Properties of Forged Steel Base Material: The raw material is selected from national standard 45# high-quality forged steel. High-temperature forging eliminates internal porosity and looseness defects, ensuring continuous and intact metal fibers. Its shear and bending resistance far exceeds that of ordinary stamped thin-material straight locks. Low-priced stamped straight locks on the market are prone to wedge head breakage and lock body deformation under vibration and repeated hammering. Our straight locks have undergone thousands of fatigue hammering tests without plastic deformation, and the pull-out force of a single node consistently exceeds 3kN, meeting the mandatory standard that the lock must not fall off after hammering self-locking. The nodes will not loosen on their own under continuous concrete vibration and strong wind disturbance conditions.
Ringlock Straight Lock Product Features Self-adaptive self-locking wedge structure characteristics: The wedge surface slope has been optimized through mechanical simulation. The gap between the lock head and the inner wall of the small hole in the disc is controlled within a reasonable range. After hammering and sinking, a mechanical self-locking is formed. The greater the load on the crossbar, the stronger the wedge surface compression force, resulting in a tight and slip-free engagement. Unlike simple pins without slope, this product has a reverse anti-disengagement limit. When the frame undergoes slight deformation or the rods shift slightly, the lock will not slip out of the hole, avoiding the dual safety hazards of small parts falling from heights and joint detachment.
Fully hot-dip galvanized corrosion-resistant characteristics: The entire set of direct locks undergoes a complete process of degreasing, pickling, fluxing, and hot-dip galvanizing. The zinc layer thickness is stable at 70μm, with no uncoated dead corners on the wedge surface, shoulder, and hammering tail. Long-term use in coastal salt spray, high-humidity tunnels, and northern snowmelt corrosion environments will not result in rust or wear on the wedge surface or expansion of the hole diameter. It maintains stable self-locking performance even after many years of use.
Standardized Zoning and Adaptability:
The straight lock's inner diameter and wedge width are standardized during production, fitting only small holes in the disc. This makes it visually and dimensionally distinct from the oblique lock, allowing workers to quickly identify it on-site and preventing issues like insufficient engagement and reduced horizontal stiffness caused by misusing oblique locks on horizontal bars. New and old horizontal bars from the same or different batches, as well as 48/60 series uprights, can be freely combined, ensuring maximum interchangeability without matching jams or excessive gaps.
Ringlock Straight Lock Product Application Scenarios:
Building Scaffolding (Interior and Exterior): High-rise residential and commercial complex external protective scaffolding, full-span internal support scaffolding. Straight locks construct regular horizontal trusses, ensuring secure locking of each horizontal bar node and improving the overall lateral displacement resistance of the scaffold.
Ultra-High Full-Span Formwork:
Factory, basement, and convention center large-span roof support. Multiple layers of horizontal bars are densely packed, and numerous straight locks bear the horizontal restraint loads, preventing localized outward expansion and instability of the scaffold.
Municipal rail transit projects:
Temporary support inside subway stations and tunnels; in damp and watery underground environments, the corrosion resistance of hot-dip galvanized direct-locking systems is evident, ensuring long-term stability at construction nodes.
Bridge pier and cap beam support:
In heavy-load bridge construction, multi-layered horizontal crossbars rely on direct-locking systems to form a continuous force-bearing system, dispersing the lateral impact force of pouring concrete.
Overseas export projects:
Infrastructure projects in Russia, Turkey, Indonesia, etc., adaptable to the formwork construction standards of multiple countries; long-term use without rust or failure in high-salt coastal construction sites.
