The Importance of Hangers & Brackets in MEP Installation
Before drawing the architectural design of a building, the architecture must first consider the overall design of the building so that he gives allowance fit for construction attachments, the support system for pipe works, and systems anchoring tools to ensure that the structural design of the building can support all piping and wiring loads.
Hangers and brackets in MEP Installation play an important role in putting in place a workable MEP infrastructure and are provided for and fixed in place by the MEP engineering contractors as per the best MEP design technologies.
What are hangers and brackets in construction- MEP Installation
Brackets and hangers are important tools used in MEP design technologies as support gadgets for pipe works, electrical installations, and mechanical installations. They are different in shapes and sizes but all work together to make a building serve the intended purpose.
An engineering assignment service specialist throws more light on this. Hangers are metals mostly U in shape and are used for supporting the end of the floor joint. The hanger gets its support by joining to beams together using hard nails. There are different types of hangers manufactured to provide effective support to various weights of beams and shapes.
Jiffy hangers – they are used to abut two timbers together and have several holes to push a nail screw through.
Joist hangers – they hold joists together and are used for holding decks, floors, and ceilings together.
It is a device made of wood, metal, or stone that hangs over walls to hold weights in place and can also be used to support shelves, beams, and statues.
Why are hangers and brackets important in the construction industry?
Everything consisted of a building’s structure must be fixed to allow smooth flow of the systems that serve the building. They include critical systems like the piping works, electrical installations, and mechanical installations.
As per an expert college paper writer, if the systems are not installed well so that they are held in place firmly within the building, they affect other issues like how comfortable the occupants are, how the systems function, and their effectiveness in doing their work.
Some of the important components in the structure of a building are hangers and brackets, which act as supporting tools for the MEP installations and are supplied by MEP contractors.
During the construction process, delays could occur due to the complexity of procedures followed when installing ducts, which could have an impact on the estimated building costs.
If the construction engineers limit space needed for ceiling installations, MEP contractors could have a difficult time trying to fix everything together in a limited space, which could adversely affect the functionality of the piping works, electrical and mechanical installations.
Architectural engineers and MEP teams should therefore work as one team to avert such challenges. Once the primary structures, which include the column, beam, and slab, are put in place, the MEP experts should come on-site and set their installations in place to ensure the agree with the primary structure and if there is a disparity, the building structure has to be adjusted until they align.
How A MEP installation gets supported on ceilings
Piping works put greater weight on the ceilings as compared to electrical works because piping includes weighty ducts, fire pipes, sewerage pipes, and water pipes, while electricity includes wires and conduits.
To ensure they do not fall off, they get clipped by hangers at three-meter intervals either in a horizontal angle using steel held on clamps or a vertical angle that gets suspended using gadgets that are fixed in the concrete.
Engineering and remodeling advisor for a top UK essay writing services and academic proofreading suggests that if the ducts are light including the tray, panels, wires, and pipes, they are held in place on anchors that drop from the concrete and fastened with bolts and hooks.
Challenges faced by the old installations support system
The main challenges engineers face when using the old support systems include;
- The complexity of the processes – the slots have to be welded and this could lead to losses and wastage because it calls for skilled labor
- Less productive – it is hard to put markings and anchoring is hard
- Approvals are not realistic- there are proper approval systems in place for anchors and frames and supporting components that are mostly fixed on concrete and may, at times, fail to cause the MEP systems to fall off and threaten lives.
What are the qualities of good MEP support systems?
Good MEP support systems will include the following
- An anchor that will perfectly work in case of fires and tremors
- High tech frames and supports for wiring which are not prone to extreme temperatures and tremors
- Support systems that have gone through approval stages.
Hangers bring together anchoring systems and framing and are tested and pass by assessing authorities. They are also beautiful, not heavy, and are manufactured in a friendly ready for use manner for ease of use and support.
The support systems’ components include anchors, wire with stud, bolt, non-key blocker, hooks, protection for corner ducts, and sleeves. Any hanger that passes the test for the above qualities can be used in any building to support loads as heavy as over 250kg for each support.
The support systems are also pliable enough to allow installable for suspended systems. MEP designers must allow ample space for installations ceilings and the floor above, something that most clients ignore.
Such steps could lead to the building ceiling lacking enough space for installations, which could force engineers to cramp everything at a tighter level. On the other hand, architectural designers and installations engineers must have understood that hangers and the supporting systems must run in agreement with the structure of the building, and therefore, they must allow proper space for MEP installations.
Determining factors for space requirements for MEP installations
As we have discussed above, mechanical, electrical and pipe installations in any building require enough space above the ceiling so that all the installations fit well above. If the space is small, the engineers will have to squeeze everything there is to clear the clogged way, which eventually displays negative outcomes.
If space is enough, the installations will fit well and function well. If the installations are to work well, engineers must ask themselves the following important questions:
- What is the thickness of the insulators?
- What is the distance needed for the clearance of installations?
- What are the dimensions of the pipes’ work, lighting installations, and ducts?
- How many supporting pieces are needed – hangers and brackets
- Are there any crossovers like ducts, pipes, sprinklers?
- How big is the beam supporting the structure?
- What are the dimensions of the joists?
Things to include during piping work design
The main consideration of installations by engineers is to ensure there is enough space for installations for the hangers and brackets work well. There are situations where the installation support systems could fail to fit in the spaces provided, leading to hanging piles with put any support.
The hanger support is as important as the installations. As a result, engineers must consider the following:
- Hanger space: ample space must be provided for hangers and brackets and their components
- Contraction & expansion: the hangers must be given space for expansion due to heat and contraction due to cold otherwise, they would break off and endanger lives
- Detailed information on attachments: the engineer must clarify if there could be a need to complement hangers with thermal anchors and if the law has provided for it
- Heavy pipes: if heavy pipes shall be used, where will the hangers be located and will there be a negative effect on the building structure
- Anchor guides: where will anchors be located, including bend, guides, and joints for expansion
Other hunger considerations during the design process
The engineer should give priority to these details when designing MEP systems:
- All heavy pipes must be independent and not get support from the building ceilings or roofs. Instead, hangers should be used to provide support and no pipe should be supported by another pipe, but each must be independent.
- Engineers must countercheck all hanger support systems to make sure they are well placed in the design to avoid changes and adjustments during the actual installation processes.
- If several pipes are supported by a common trapeze, increase the hanger diameter and decrease the hangar space allowance as per the size of the pipes from the widest to the narrowest.
- Provide for the correct sizes of hanger for piping work and support for anti-fire systems which comply with the law
- Provide for supplementing tools like steel to give support to the whole MEP installations and ensure there are rough edges and sharp corners left to avoid an accident and cut wounds.
How to install hangers and brackets
- The maximum spacing between hangers must not exceed ten feet without regard to what MEP installation it is.
- Use clevis hangers for supporting horizontal pipes.
- Use trapeze hangers to support several pipes together. Light trapeze is used for light loads, while heady trapeze is used for heavy loads.
- Use steel brackets to support vertical pipes.
- For hot water piping, use hangers with cradles, and for larger pipes, use roller hangers and trapeze hangers for the large insulated pipes.
- Provide approved steel saddles for protection when you use hangers that use piping rolls
- Pipes that are likely to move vertically or horizontally should be supported using spring hangers.
Adjusting pipe slopes
You provide adjustments for piping slopes through the installation of hangers to show slopes and therefore allow deflection
- Set the hangers well in a way they can bear the load weight effectively without collapsing
- Ensure the hanger can allow for adjustments resulting from vibrations of pipes
- Through approvals by engineers, you may attach hangers on beams directly though it is not allowed and should only be done under unique circumstances.
Pros and of using brackets and hangers
Brackets are usually pre-cut and are good for supporting MEP installations and come in various shapes.
- They save time because their channels are pre-cut
- They have a fast suspension speed because they have the alternative of using clamps or trapeze during installations
- they have several faces meaning they can provide support through bolting or suspending using wires they are safe than the old support provisions
Brackets come in varying shapes and sizes but the most commonly used brackets are the following:
Low profile brackets
- They have metal frame channels and are used in situations where pipes require mounting near to soffit
- They can be easily installed and have clumps with ¼ turning attachments
- They save labor, time and removes the need to cut a channel on site
- They are adaptable and useful for suspension of header nails
- They easily give support to MEP installations.
- They are perfect fits for clamps and suspend easily.
- They fit well with a trapeze for suspending electrical installations fast.
How to determine the right brackets to use
The material it is made of
Brackets are made from various materials, including metal, bronze, steel, and iron. Some others are made of stone or concrete. You determine the right bracket for your building by determining the weight of the material/item you want the bracket to hold. If the support needed is heavy, use brackets that can hold heavier weights, and if it’s light, use a bracket that can hold lighter weights.
The shape of the bracket
Brackets can fit into varying shapes of walls, corners, roofs, and so on. If the place you are fitting the bracket is spherical, use a spherical bracket, and it’s rectangular, use a rectangular bracket. There are twisted brackets, smooth bracket, and many more.
As per the rules discussed above, heavyweights require heavy brackets while lighter weights require lighter brackets. This is to ensure the load above is held in place to avoid collapsing in the future leading to accidents or even death.
Hangers and brackets continue to play a central role in setting a conducive environment for building owners and tenants as well. MEP engineers ought to collaborate perfectly with structural engineers to create a seamless flow between the building structure and the MEP installations by providing ample space for the above ceiling installations to avoid clumsy work that will bring disappointments to building owners.
