What is the use of expansion joint in a building?
Expansion joints are separations between structures, simply gaps, to allow them to move and reduce stresses that may occur. Often, these gaps are filled with an Expansion Joint System to fill in the void to ensure walkability, a complete building enclosure, waterproofing, and general serviceability of the structure.
What are the three 3 primary methods to accommodate pipe movement in risers using Victaulic flexible couplings?
Three common methods of accommodating this pipe movement are to 1) provide an expansion joint; 2) allow the system to “free- float” whereby the pipe would be allowed to move in a desired direction through the use of anchoring and/or guidance, if necessary, taking into account the capability of branch connection or …
Where do you put expansion loops?
1. The expansion loop is usually located on the side of the hottest line. 2. The expansion loop, as a rule, should be located in the center of the distance between two anchors.
Where do you need expansion joints in concrete?
Concrete expansion joints are particularly important where there have been consecutive concrete pours and are also useful when laying concrete within an area bordered by walls or buildings or if objects such as manhole covers need to be incorporated.
Where are expansion joints placed?
Expansion joints are put in place before the concrete is poured. Expansion joints are used to allow the slab to move and not put stress on whatever it abuts. These joint are placed where a slab meets a building, where a slab meets another slab, and where a pool deck meets the coping.
What is Victaulic pipework?
Victaulic pipe couplings are used to connect pipes of various pipe materials and across multiple fire protection, industrial and commercial applications. Choose from our selection of couplings, including rigid, flexible, shouldered, transition, reducing and plain end pipe joining couplings.
How do Victaulic fittings work?
The pipe groove is made by forming or machining an actual groove into the ends of two pipes. A gasket wraps around and on top of the pipe ends, the housings wrap around the gasket and sit in the pipe grooves, and the bolts and nuts are tightened with a wrench to hold it all together. angular movement.
Why expansion loops are required?
Expansion loops provide sufficient flexibility to prevent thermal expansion and contraction from causing excessive stresses in the piping system. Expansion loops often are required in high-temperature gas well flow lines and gas and water injection lines.
How many joints are in concrete?
There are three types of joints: Contraction Joints, Construction Joints and Isolation joints. The most common are contraction joints which control cracks which are caused by restrained shrinkage, loads and other stresses. The joint depth should be AT LEAST ¼ of the slab thickness.
What are the joints called in concrete?
In slabs, there are three types of joints: Isolation joints (also sometimes functioning as expansion joints) Construction joints (which can also function as contraction joints) Contraction joints (also sometimes called control joints)
How do you install an expansion joint in concrete?
Installation Instructions
- Unroll and cut to length.
- Attach to adjacent material before pouring concrete. Attachment can be made with construction adhesive, nails or staples.
- Expansion Joint material includes a built-in “tear-off” strip.
- Pour concrete and finish.
- Exceeds ASTM Standard D-7174.
What is Victaulic fitting?
Victaulic couplings, or mechanical grooved couplings (also called mechanical pipe joining systems), are components that join mechanical pipes together to create a watertight joint.
Where are expansion loops positioned?
The expansion loop is usually located on the side of the hottest line. The expansion loop, as a rule, should be located in the center of the distance between two anchors. The height of the expansion loop is normally twice the width.
What is a metraloop?
The Metraloop is called an expansion joint, but it is really much more dynamic then a typical expansion joint. The typical Metraloop installation is axial for thermal applications, or in any possible direction for seismic applications. And when we say… Created with Sketch.
What is the typical metraloop installation direction?
The typical Metraloop installation is axial for thermal applications, or in any possible direction for seismic applications . And when we say any possible direction that includes axial, lateral and angular.
