Plank Couplers - Durable & Versatile Scaffolding Clamps
Types of Plank coupler
A plank coupler is a type of construction equipment used to join and support planks, often in scaffolding systems. These couplers provide a secure connection between planks, ensuring stability and safety. There are different types of plank couplers, including the following:
Gongde supply professional and honest service.
-
Fixed or Right Angle Coupler:
The fixed or right-angle coupler is a type of coupler used to connect two horizontal tubes to a vertical tube. This coupler is usually installed in corners where the horizontal and vertical tubes meet at a right angle. The fixed coupler is made using two halves that are fixed to the vertical and horizontal tubes using bolts and nuts.
Scaffolding workers have to be in the same plane for this coupler to be used. It is widely used in scaffolding support structures because it provides a strong and rigid connection.
-
Swivel Coupler:
The swivel coupler is another popular type of coupler in the scaffolding industry. It is used to connect two scaffold tubes at any angle. The swivel coupler is ideal for connecting tubes in both vertical and inclined positions. It is also used for making tubular scaffolds in arched and circular structures.
The swivel coupler is made of two distinct tubes that are welded together. The first tube is welded to the horizontal tube, while the second one is connected to the vertical tube. A locking pin helps to hold the second tube in place. This pin is located in the swivel joint.
-
Adjustable Coupler:
The adjustable coupler is a type of coupler used to connect two tubes that are not in alignment. It can be adjusted in both vertical and horizontal directions to make sure the tubes are connected securely. This type of coupler is important in situations where the tubes are misaligned due to uneven surfaces or specific design requirements.
-
Double Coupler:
The double coupler is a popular type of scaffold joint that connects two horizontal tubes. It is used when extra strength is needed, like in the case of bridging gaps or supporting heavy loads.
The double coupler has two sets of clamps and one set of bolts. It is also known as a double putlog coupler.
-
Putlog Coupler:
This coupler is used to connect a putlog to a vertical standard. It is connected to an integral part of a wall or a shed roof. The putlog coupler is made of a single clamp and one bolt.
Functions and features of plank coupler
Steel couplers for scaffolding join steel tubes to create a scaffold plank. The coupler's threads are welded on one end of the tube and fitted with nuts to connect to another tube's end when the tube is cut. Some of the features of a coupler are:
-
Carbon Steel Material
The construction of the coupler using carbon steel makes it durable and able to withstand heavy loads. The carbon content in the steel can range from 0.3% to 1.5%, which depends on the strength and hardness required for the coupler. The steel is also treated with heat to increase its strength and ductility.
-
Hot-Dip Galvanization
The scaffold coupler undergoes hot-dip galvanization, which involves immersing it in molten zinc. This treatment coats the couplers with zinc, making them more resistant to corrosion and weather elements. The couplers can be used in construction projects that take place in different environments.
-
Simple Installation
The installation of the scaffold couplers is simple and straightforward. The nuts are easily connected to the welded threads of the tube, providing a tight and secure connection. The ease of installation reduces the time and labor costs required to set up the couplers.
-
Nylon Safety Covers
The coupler has nylon safety covers that are installed on the bolts and nuts. The covers help to prevent accidents and injuries on the construction site. They protect workers from sharp edges and protruding threads, ensuring a safer working environment.
-
Pipe Diameter
The diameter of the pipe that the coupler can fit ranges from 48.3 mm to 48.5 mm. The outer diameter of the tube must be within this range for it to be connected securely. The coupler can be used on different tube sizes in construction or scaffolding.
-
Load Capacity
The coupler can support up to 3.5 tons, depending on the installation and orientation. The load capacity can also be affected by factors such as the condition of the tube, length, and material used. Proper installation increases the load capacity of the coupler.
Scenarios of Plank coupler
The plank coupler has multiple applications across various industries. These are some common usage scenarios:
-

How to choose plank coupler
When selecting a coupler for a project, there are some factors to consider to ensure the availability of a suitable product. Some of the factors to consider are:
-
Load Capacity
The coupler should be able to support the load. This includes the weight of the beams and any additional weight that will be added. Consult the manufacturer to know if the coupler can support the intended load.
-
Material Strength and Durability
Plank couplers are made of different materials. Each material has its own strength and weaknesses. Consider choosing a coupler that can withstand environmental conditions without damage.
-
Adjustability
Some couplers are adjustable while others are not. Adjustable couplers can be used in different settings and can accommodate various beam sizes. This type of coupler offers flexibility during construction.
-
Ease of Installation
Choose a coupler that is easy to install. Some couplers require special tools while others do not. Consider the time and resources that will be used to install the coupler. A coupler that is difficult to install will increase the cost of construction.
-
Compatibility
When choosing a coupler, consider its compatibility with other structural components. This will ensure the integrity and safety of the whole structure. If the coupler is not compatible with other components it can lead to accidents.
-
Safety Standards
All couplers are required to meet some safety standards. When choosing a coupler ensure that it meets the required safety standards. This will ensure the safety of the whole structure and prevent accidents.
-
Cost
The cost of the coupler is an important factor to consider when choosing a coupler. Different couplers have different prices depending on their features. It is important to consider the budget and choose a coupler that is within the required price range.
plank coupler Q&A
Q1: What are the different types of couplers?
A1: There are several types of couplers, including the swivel coupler, fixed or rigid coupler, and matrix coupler. The swivel and rigid couplers are as described above. The third coupler, the matrix, connects three beams at a right angle. It is a strong coupler and is mainly used in matrix bracing systems.
Q2: What is a double coupler?
A2: A double coupler is a type of structural steel coupler. It connects two horizontal or structural steel pipes. The connection is stable and secure. Like other couplers, it has two main tubes, a locking mechanism, and a third tube, which is the horizontal or vertical tube.
Q3: What is a sleeve coupler?
A3: Sleeve couplers are used to connect the ends of two steel tubes/construction pipes. They consist of a steel tube (the sleeve) that fits over the ends of the two other tubes/rods.
Q4: What is the difference between a coupler and a connector?
A4: Couplers and connectors serve similar purposes but have some distinct differences. For example, couplers are used to connect two or more of similar products/structural elements. Connectors, on the other hand, are used to connect different structural elements. For instance, a connector can connect a beam to a wall or a truss to a roof.
