Hi Load N (H) Formwork Frame Scaffolding

Hi-Load N(H) Formwork Frame Scaffolding

Hi load N (H) formwork frame scaffolding is a formwork frame system shoring tower formed by scaffolding N (H) frames with components of cross braces, lower adjustable feet and the shoring parts of four-way heads supporting the formwork beams and film-faced plywood. While N frame connectors, fixed by cotter (pins and splits), make the scaffold formwork shoring tower reach a required slab height vertically in construction.

The scaffolding N(H) frame is made of two O.D. 60 mm high-strength scaffold tubes as vertical legs, two O.D. 48mm scaffold horizontals, and one diagonal brace, forming an N(H) in shape. This design can support greater loads in the concrete shoring, has a light self-weight, and is economical.  It was initially designed for high-load slab-shoring construction in Uzbekistan and is now used globally for its proven strengths.

In construction and shoring, heavy-duty (HD) formwork frames need to be assembled into a scaffold shoring tower to reach the required height, length and width.

N Frame Formwork Scaffold Load Capacity

The ultimate load capacity of the N formwork frame scaffold is 583 kN. See the following test report.

Note: The load capacity test is an ultimate centre load test for a one-tier formwork frame tower measuring 1.5m wide, 2.0m high, and 2.0m long.

N Formwork Frame Scaffold Shoring Tower

One set of N-frame formwork scaffold shoring tower consists of two N-shaped formwork vertical frames, two sets of diagonal cross braces, horizontal braces, four sets of coupling pins, four sets of cotter pins (pin and split), four adjustable top head jacks(adj fork heads), and bottom jack bases. These components help the shoring scaffold tower reach the required height, length, and width during the concrete shoring. It is also called a concrete load-frame scaffold or a floor-formwork frame scaffold.

During construction shoring, the adjustable four-way top heads (adj fork heads) are inserted into the vertical tubes at the top of the O.D. 60 mm N-shaped scaffold frames, supporting formwork beams(timber H20 or aluminium beams) from four directions in the concrete shoring. The adjustable jack bases are placed at the bottom of vertical frames to adjust for uneven ground.

One single scaffold tower size is 1.5m wide, 1m to 2m long, and can reach a maximum height of 4m.

N Fromwork Frames

The main parts of the N-shaped scaffold tower are the vertical formwork frames. In concrete shoring construction, they are the primary load-bearing components of the entire scaffold shoring tower.

A vertical formwork frame consists of two vertical tubes, two horizontal tubes, and one diagonal tube, forming an N-shape.

The vertical tubes of the N-shaped formwork frames are 60mm in diameter, allowing them to support greater loads from the concrete slabs. Two lock pins are welded onto the vertical tubes. The lock pins connect the diagonal braces (cross-bracing) of the formwork shoring system.

The horizontal tubes of the N-shaped vertical frames are made of O.D. 48.3mm scaffold tube. Sometimes, they also have lock pins on. These lock pins connect to the horizontal braces (X bracing), making the high-load shoring frames more stable and capable of withstanding greater loads during construction and shuttering.

The standard width of the vertical frame is 1500mm. Customised width is available.

The standard height of the vertical frame could be 900mm, 1100mm, 1200mm, 1800mm, or 2000mm.

The vertical frames are connected by spigot pins during erection to form the required height of scaffold shoring towers to support the concrete slab.

N Formwork Frame Diagonal Braces

Diagonal braces are essential components of the heavy-duty formwork frame towers. They fix two frames horizontally and form the frame tower sets.

Diagonal braces are usually used in a cross, forming X-shaped bracing in the formwork scaffold tower. This makes the heavy-duty shoring tower more stable without moving and shaking under high loads.

There are holes on each end of the diagonal braces—the holes connecting to the lock pins on the vertical frames.

N Formwork Frame Connector(Coupling Pins)

Coupling pins are connectors between two frames vertically. These components help the high-load formwork frame tower reach the required height in the slab concrete.

During erection, the coupling pins are secured by the cotter pins (clevis pin and slip).

Clevis Pin and Slip (Rivet with Slip Cotter Pins)

A clevis pin and slip is a rivet pin with a cotter. It can secure the coupling connectors and make the formwork shoring tower stable and safe.

Four-Way Head Components

The four-way heads are the top heads that have four forks at the top. They support the formwork beams (H20 timber beams, Aluma beams (aluminium beams), steel beams) in the concrete shoring.

Lower Adjustable Components

Lower adjustable components are placed at the bottom of the vertical shoring frame parts. They are the starters or feet of the whole shoring frame tower, used to level the horizontals to ensure the scaffold tower’s stability on uneven ground.
