A construction joint is required to allow the structure to be built. Say there is an existing structure in the way of a wall. Part of the wall is built, then later the existing bit is removed, and the rest of the wall constructed. The place where the first and second parts of the wall meet is a construction joint. This kind of joint is usually built so that no movement is allowed. An expansion joint is one that allows movement between the two elements. There will be a comparitely soft material, such as rubber, asphalt or impregnated board placed between the parts. The latest innovation has lead to use non bituminous filler boards like polymer based HD100 board. It is also known as micro cellular filler boards. (More details about filler boards you have to visit hd100.in or kampun.com from there in-depth product knowledge available.) If it is concrete construction, any reinforcing bars will be arranged to allow movement. In most cases, if movement was prevented, the structure would crack or buckle. The joint allows controlled movement.

The difference between contraction joint and construction joint?
A construction joint in concrete jobs is a joint where a fully set and hard concrete joins a fresh concrete to make a joint. Normally, cracks would occur at this joint because concrete was not cast monolithic. A contraction joint is joint between two concrete edges so formed which allows minute movement between the two edges caused by heat or some other external forces. Usually, contraction joints are also referred to as expansion joints.
What do you put between slabs after laying them?
in between existing concrete and the new concrete you need to place an expansion joint in between the two.
What is the construction joint in water retaining structure?
The reinforced concrete construction is the construction joint in water retaining structure.
What is the approved location of the construction joints in the raft foundation?
The best location to set the construction joint is less shear force impact. e.g:In slabs;it is better to locate between the supports.
What is the difference between pin joint and hinged joint?
in pin joint the linkages are free to move relative to one another angularly, whereas in hinge joint, one linkage is fixed and the other is free to move in angular direction.

What is an expansion joint in construction?
An "expansion joint" is a joint left in between sections of the same material, like concrete or steel, that allows movement as the material heats up or cools down. Without it, concrete, for example, can expand and crack in hot temperature.
What is the difference between Rubber Expansion joint and Dismentaling joint?
A Rubber Expansion Joint and a Dismantling Joint are both used in piping systems, but they serve different purposes. A Rubber Expansion Joint is designed to absorb vibration, reduce noise, compensate for thermal expansion and contraction, and accommodate minor pipe movements or misalignment. It helps protect piping systems and connected equipment from stress caused by pressure changes and mechanical movement. A Dismantling Joint, on the other hand, is used to simplify the installation, maintenance, and replacement of pipeline equipment such as valves, pumps, and flow meters. It provides adjustable length, allowing components to be removed or installed without cutting the pipeline. Unlike a rubber expansion joint, it is not intended to absorb vibration or continuous movement. In summary, a rubber expansion joint improves pipeline flexibility and reduces stress, while a dismantling joint makes pipeline assembly and maintenance easier.

Why do you use a construction joint?
Construction joints are very useful, the expansion & contraction made is made in summer & winter season respectiely. In summer coz of temprature concrete get expansion in mm but it damage the structure, that's why construction joint is provided. Sunil Nagargoje TESPL
What is a perpend joint in construction?
a perpend is a vertical joint between adjacent masonry units
What is the difference between a DIP joint and a PIP joint?
Distal interphalengeal joint & Proximal interphalengeal joint
How do you provide expansion joint in slab beam construction 75 meters in length?
The purpose of expansion joint , is to anticipate movement of structure due to temperature, earthquake,settlement. In 75 mtrs length of slabs we can make expansion joint in L/2 or 75/ 2 or L/ 3 for every 25 mtrs , we provide bearing Pads for movement. , actually this also name as movement joint.
Do you need an expansion joint for a gunite pool between the coping and patio?
Absolutely
Where can expansion joints be bought?
An expansion joint is used in construction to help deal with the effects of building materials expanding and contracting. They can be purchased through hardware stores like Home Depot.
