Shree Hari Engineering

The Scaffolding Adjustable U Head Jack jack stirrup head is used at the top of the vertical cuplock standard in order to provide an additional maximum adjustment of length. The main application of these types of U-Jacks is to hold MS beams and channel in places, upon which the shuttering plates are placed during the construction. The U-Jacks are manufactured using the Roll Threading process, which increases safety and enables them to have a load-bearing capacity of up to 4 tons.

Other Details:

Shree Hari Engineering is very known in importing wooden beams which are normally called in construction industry as H-Beams (Timber). These beams are manufactured under stringent quality measures. This concrete support H-Beam is aunique introduction to overcome the cumbersomeand costly procurement of timber. H-Beams are designed to withstand various loads during construction activities.

The wooden flanges are made of chemically treated, seasoned timber. Using a unique finger jointing method, the webs are manufactured by joining these Flanges with boiling water-proof plywood / Timber and thus made as a monolithic timber beam. Both the flange and web is hot processed by wedge technology to makeita composite versatile section.

H-beams Are Available Sizes:

• H-20 (20 cms depth)
•  Lengths vary from 1.8m to 5.9 Mtr for H-20

Timber H-Beam for formwork is used for concrete formwork construction. H20 timber beam is widely applied in slab Formwork systems, wall formwork systems, column formwork systems, timber structures, and other temporary bearing structures.

Characteristics:

• Solid Flange : Sawed-Pine or Spruce imported From Finland, High quality spruce; High stability
• Solid web: Birch or poplar or larch plywood; High durability; High load bearing capacity
• Treated by WBP glue exterior used weather & water-proof
• Beam ends sealed: Protect from moisture & UV; Reduce damage; Increase service life
• With high standardization, universal property, Fast operation.
• Highstiffness, light weight, strong load-carrying capability.
• Low cost, recycle resource.

The Cup lock System:
This is one of the most Flexible types of scaffolding systems that can be used for the construction of slab floors. Some of the main features of this particular system is the ease with which it can be used even in cramped and narrow spaces. The system consists of only a few components, which are very easy to assemble, thereby improving the convenience related to Finding solutions For level difference during construction.

Basic Structure:
The basic unit of a cup lock scaffolding system consists of Four horizontal elements which are fixed at a single point along the vertical element. The same elements which are part of the system can be used to create suitable solutions for the purpose of assembling a stair tower, due to the high load bearing capacity associated with the system.

The vertical elements in the system are equipped with locking kits, which are welded onto them at intervals of 500 mm or 1000 mm. This offers an economical and practical solution For projects which have level difference at the ground or at the deck. The locking kit consists of bottom and top cups, of which the bottom cup is welded onto the vertical element. The top cup or the upper cup is moveable along the length of the vertical element.

With the mobility of the upper cup comes the responsibility of ensuring that it is not removed from the vertical element completely, owing to the structural difficulties that could occur due to the misplacement of the same. The heads of the horizontal elements, which are structured out of both ends of an element, are Fixed between the cups along the vertical elements. With the help of a hammer, the upper cup can be rotated in the clockwise direction and the head of the horizontal element is squeezed rigidly between the upper and lower cups.

A scaffolding horizontal ledger is a key structural component in a scaffolding system, particularly in tube-and-clamp or modular scaffolding. It serves as a horizontal bar that connects vertical standards (or uprights) to create a platform for workers and materials.

1. Function: It provides the horizontal stability and support needed to hold the scaffold structure together. The horizontal ledger connects the vertical standards at regular intervals, creating the necessary framework for additional levels of the scaffold to be built.

2. Material: Typically made of steel or aluminum, the ledger is strong and durable to support the weight of workers, tools, and materials. Steel is often used because of its high strength-to-weight ratio, while aluminum is lighter and more corrosion-resistant.

3. Length: Horizontal ledgers come in various lengths, depending on the design of the scaffold and the spacing between vertical standards. Common lengths range from about 6 to 12 feet.

4. Connection: The ledger connects to the vertical standards using clamps, pins, or other fastening mechanisms. In tube-and-clamp scaffolding, a clamp is used to secure the ledger to the vertical tubes. In modular scaffolding, pre-designed connectors are used for easy assembly and disassembly.

5. Load-bearing: The horizontal ledger is designed to bear the load of the scaffold decking, the workers, and any materials on the platform. The load is transferred to the vertical standards, which ultimately distribute it to the ground.

6. Positioning: Horizontal ledgers are typically positioned in a grid-like pattern, with horizontal spacing between them. The ledgers are aligned in levels, and additional cross braces and diagonal supports are added to stabilize the structure further.

7. Types:

   • Straight ledgers: Used to form the main horizontal lines of the scaffold.
   • Transverse ledgers: Positioned across the scaffold to form the transverse framework.
   • Bracing ledgers: Sometimes used for extra support in certain scaffold systems.
