What’s the Importance of Using Lap Rebar Splices?
The lap rebar splice is the most common and economic rebar splice used in the construction project. Compared to lap rebar splicing, the welded rebar splices and mechanical rebar splices require more labor and skill.

Introduction of Tension and Compression Mechanical Splices for Rebars
This type of mechanical rebar splice can resist tension and compression stress. There are sizable numbers of commercially manufactured tension and compression mechanical splices for rebars. Tension and compression mechanical rebar splices types, designated bar sizes to be spliced by each splice type, the grade of the steel bar which is spliced using certain types of tension and compression mechanical rebar splice, and installation condition of each mechanical rebar splices are provided.

What Are the Methods of Splicing Reinforced Bars?
Most of the reinforced concrete structures won’t be provided with full-length rebars. The manufacture and transportation of long bars are difficult, which limits the use of full length reinforced bars. The method used to join the reinforcement bars, so that the force is transferred effectively from one rebar to the other rebar is called as rebar mechanical splicing. The integrity of the concrete structure is dependent on the proper mechanical splicing of the reinforcement bars.

Operations in Rebaring for Reinforced Concrete Works
The three main operations carried out in rebar for reinforced concrete construction bars are cutting, bending and tying. The diameter of reinforcement bars used reinforced concrete work mainly ranges from 6 to 42mm. These reinforcement bars come from the steel mill in specified lengths.

Equipment Used for Rebar Techniques
The usage of chisel and hammer was an earlier practice used for rebar bending. The rebar is held fixed with the help of three thick rebars over a rebar bender bench. Then the bending is done by means of manual force, operated with the help of levers. To tie the rods, cutting pliers were used, and tied by steel wires.

Safety Issues During Scaffolding Works
Improper scaffolding works will result in hazards. Fall hazards have occurred if the scaffolds are not properly erected or used. Every scaffolding must be erected with strong foot bearing plates to avoid collapse. Following the safety practices during scaffolding works can help to prevent injuries and fatalities.

What are the Types of Mechanical Splices for Rebars?
Mechanical rebar splices for rebars in concrete construction is an effective method of joining reinforcing bars. These are designed based on codes of standard practice. Mechanical splices in reinforced-concrete construction should meet the building code requirements for developing tension and compression as required

Equipment Used for Cutting of Reinforcement Bars
#1 Electric Rebar Cutters Electrical cutters that can cut diameters up to 16mm are employed. These consume power to cut the bars. Higher varieties are available in the market. #2 Heavy-Duty Rebar Cutter These are a higher version of the same, the heavy-duty cutters, that have the capability to cut the bars up to 42mm. At a time, these cutters can cut three to six bars at a time. These cutters make use of oil bath lubrication, which makes the operation noiseless. The system is simple and hence easy to use.

Rebaring Equipment Used for Tying Rebars
The equipment that is used for rebaring operations is developed with time, as the size of bars is increasing. Larger size bars are difficult to be handled by hand operation. For rebar machines, there are not only rebar thread rolling machines and rebar cutting machines, but also the rebar tying machines. For rebar tying machines, we supply both manual machines and automatic machines.

Necessity of Rebar Connection System in Reinforced Concrete Construction
The steel reinforcement mostly is divided into two categories i.e. #1 Primary reinforcement or main steel reinforcement #2 Secondary reinforcement or distribution reinforcement Main steel reinforcement bars are employed in R.C.C structures to ensure resistance against the whole design loads coming over it. The secondary reinforcement bars are mainly employed due to durability as well as for aesthetic reasons.

What is Rebar Connection System in Reinforced Concrete Construction?
Mechanical rebar splice technique in reinforced-concrete construction is a method for proper fabrication and placement of reinforcement bars per the design and drawings for reinforced concrete construction. As we know that concrete is very strong in compression and weak in tension. The reinforcement bars or rebars are good in tension, which is incorporated with concrete to make use of its tension property.

Requirements On Formwork System To Guarantee The Safety of Workers
The fulfillment of the below requirements would guarantee a safe, strong, and robust formwork system and provide safe working conditions for laborers. Formwork is a temporary mold into which fresh concrete and reinforcement are placed to form a particular reinforced concrete element. It supports part or the whole of a permanent structure until it is self-supporting.

Technical & Functional Requirements On Formwork System
There are several requirements that the formwork system needs to meet, otherwise, it would not serve its purpose adequately. In order to make sure that the formwork system fulfills its design goals, the designer and site engineer should take technical, functional requirements of the formwork into consideration.

What Are the Benefits of the Immediate Flange Leakage Detection?
When the Flange Leakage Detection and Repair requirements were developed, it is estimated that petroleum refineries could reduce emissions from equipment leaks by 63% by implementing a facility's Leakage Detection and Repair program. Additionally, it is estimated that chemical facilities could reduce VOC emissions by 56% by implementing such a program.
