What Is Hinge In Civil Engineering

A hinge is a builders hardware device consisting of two metal plates called leaves joined together by a pin passing through knuckle joints. The elongated strap-shaped leaves are commonly referred to as hinge.

Hinge Definition - What Does Hinge Mean in Construction?

A hinge in construction refers to a rotating mechanism that does not cause separation.

What are detent hinges?

Detent hinges are a type of hinge that offer hands-free access and a variety of positioning torques for different applications. They are also known as torque hinges or friction hinges, and allow doors or lids to stay in place at any desired angle.

What is the difference between pinned support and hinged support?

Pinned and hinged supports differ in that pinned supports allow rotation in only one direction and are resisted in the other, while hinged supports are used in three-hinged arched bridges and have a third hinge at the center of the arch. These types of supports and reactions are used in various structures and have different applications.

How do I choose the right type of hinges?

When choosing the appropriate type of hinges, it is important to consider factors such as aesthetics, purpose, and functionality. For instance, concealed hinges are ideal where the hinge needs to be hidden to improve the outward appearance of a cabinet door. It is therefore advisable to select hinges that suit the specific application and enhance the overall functionality and appearance of the product.

When choosing hinges for doors, there are three main factors to consider - the load (weight of the door), the material, and the type of hinge to use. The load determines the strength of the hinge needed to support the door's weight, while the material selection depends on factors such as the required strength and the environment (temperature, moisture, chemicals, UV radiation). Lastly, there are various types of hinges to choose from, which also impacts the door's functionality.

How many cabinet hinges do I Need?

The number of cabinet hinges needed depends on the size of the cabinet door. Most cabinet doors require two hinges, but larger doors may require three or more. Reviewing a door size and hinge count graphic can help determine the appropriate hinge count. There are different types of cabinet hinges, each with its own advantages. A video can provide an overview of the various types of hinges available and their benefits.

What types of doors require special hinges?

Certain types of doors such as pivot doors, shutters, chests, cabinets, and folding shelves require special hinges due to their unique design and functionality. Additionally, piano or continuous hinges are required for items that require a hinge that runs the entire length of the two joined pieces.

Why do I need a hinge?

A hinge is a crucial component necessary for opening and closing doors, cabinets, and other structures. It consists of two metal pieces joined by a pin, and its importance may be overlooked unless it becomes faulty and hinders proper functionality.

A hinge is a hardware device consisting of metal plates called leaves which are joined by a pin passing through the knuckle joints. It permits one part to turn on another. When the leaves are elongated, it is usually referred to as a hinge.

What is a hinged door?

A hinged door is a type of door that swings open and closed using hinges. It is typically limited in its use with hardware such as locks, closers, and certain types of hinges, which are specific to the direction of swing. The hinge backset is the distance from the back end of the hinge to the edge of the inside door surface. A knife hinge is a type of pivot hinge that resembles two blades of a knife.

How does a hinge work?

A hinge is a mechanical bearing that allows two solid objects to rotate relative to each other about a fixed axis of rotation. It typically restricts motion in all directions except for this rotation, giving it a single degree of freedom.

What is the difference between handed and hinged hardware?

Handed hardware refers to locks, closers, hinges, and other hardware that are limited to use with doors that swing in a specific direction. On the other hand, hinged hardware refers to the distance from the back end of a hinge to the edge of the inside door surface.

What is a loose pin hinge?

A loose pin hinge is a type of hinge with a removable pin that allows the two leaves of the hinge to be separated.

Hinges can be designed to rotate 180 degrees or less. In the construction industry, the term hinge typically refers to a rotation without separation.

What is a stop hinge?

A stop hinge is a type of hinge that is designed to limit the range of movement of the leaves (or plates) to a specific angle. It allows the leaves to open from a closed position to a stop angle as specified, and then remain fixed in that position. The hinge moves the leaves from an open or flat position to a specified angle and holds them in place.

What is the pin on a hinge called?

The pin on a hinge is called a knuckle and it holds the leaves of the hinge together at the joint.

What is a knuckle hinge?

A knuckle hinge is a type of surface-type hinge that consists of leaves with interlocking knuckles and provides axial movement between them. It is defined by the dimension from a point on the knuckle to the same point on an adjacent knuckle on the same leaf and the minimum dimension between the outer face of the knuckle and the opposing edge of the cutout over the hinge's entire range of pivotal movement.

A fixed support is a rigid support that resists both rotation and displacement, making it suitable for simple structures that require support, unlike a pinned support that only resists displacement. The crucial difference between the two is that a fixed support resists rotation or moment, while a pinned support does not.

What is a pinned support?

A pinned support is a type of support that can resist vertical and horizontal forces but not moments. It allows the structural member to rotate but not to translate in any direction. This type of connection is common in many structures.

Can a pinned support resist a moment?

A pinned support can resist vertical and horizontal forces but not moments. It allows rotation but not translation in any direction. Despite resisting a small amount of moment in reality, many connections are assumed to be pinned.

What is pinned support and reactions in a structure?

A pinned support or hinged support is a type of support in a structure that can resist both vertical and horizontal forces but cannot resist moment. It is restrained against translation. Equations of equilibrium can be used to find out the components of horizontal and vertical forces.

What is the difference between fixed and pinned connections?

Fixed connections and pinned connections have different effects on the behavior of structures. Pinned connections provide maximum moment at the center of the span, with tension at the bottom, while fixed connections provide maximum moment at the ends of the structure, with tension at the top. The geometry of the structure greatly affects the difference between the two types of connections.

Detent hinges incorporate a locking mechanism that keeps doors and panels open at specific angles. They provide hands-free access to the contents of cabinets and enclosures.

What is the difference between detent and bistable hinges?

Detent hinges require manual adjustment to reach a preset angle, while bistable hinges have a spring mechanism that automatically drives doors or devices to the preset angle. When specifying hinges, the ideal level of torque should be determined.
