Masonry Supports – Provide a Horizontal Movement Joint

masonryMasonry supports, or shelf angles, provide a horizontal movement joint within masonry walls. This seminar will discuss design and construction considerations, including movement control, moisture management, thermal performance, optimizing shelf angle location strategies, and accommodating structural tolerances.

Simple, effective angle bracket system designed to suit varying cavity widths. Suitable for either concrete framed structures with site-drilled expansion bolts or steel framed structures with coated setscrews.

Brick masonry walls attached to a concrete frame tend to shrink and expand at different rates due to temperature changes, moisture expansion, elastic deformation, and settlement. These differential movements are provided in a masonry wall assembly through horizontal and vertical expansion joints, shelf angles, and adjustable veneer anchors.

Relieving angles (also known as masonry support or corbels) transfer the weight of the masonry to the main building structure and allow space beneath the masonry for building movements to occur. They are installed at intervals along the wall elevation, typically at each floor level. The frequency and number of relieving angles in a wall system depend on several factors, including the height of the building, the size, and location of windows, the type of lintel or header, masonry anchorage, and the code requirements for structural movement tolerances.

While the purpose of relieving angles is clear, properly installing these metal elements can be difficult to accomplish during construction. That is due to the long lead time for galvanized or stainless steel relieving angles and a tight schedule for installing brickwork. In addition, a lack of communication and coordination between the contractor and structural engineer during the design phase can result in a mismatch between the masonry loads and the structure’s load capacity.

A common deficiency of relieving angle installation is using a sealant (typically mortar) under the underside of the relief angle. It can restrict water drainage from the masonry wall and prohibit it from meeting energy codes. In addition, the lipped bricks are often installed directly above the underside of the angle, requiring that they be cut to fit. This detail usually leaves a gap under the arch that is not sealed and may leak and deteriorate over time.

An alternative to a sealant is a flexible membrane such as Armatherm FRR or other structural thermal break material. It significantly reduces the linear transmittance of the thermal bridge and allows for the removal of the rigid metal flashing used for waterproofing.

Shelf angles are steel angle irons installed in masonry veneer buildings to support brick above a masonry opening. New construction requires them to reduce the likelihood of collapse and damage due to excessive vertical movement. They are typically installed on each floor and support the brick above that story. Like lintels, shelf angles must be engineered and properly sized to ensure they meet the strength requirements for their design. Lintels and shelf angles should also be stiff to minimize masonry cracks caused by excessive deflection.

Many multifamily building projects require steel shelf angles to achieve high energy efficiency levels and comply with state energy codes. However, these structural elements form significant thermal bridges that can reduce the wall’s R-value by up to 50%, creating costly energy losses. To limit upfront material and long-term maintenance costs, SWA recommends that these elements be limited in frequency and, where possible, offset to further reduce the thermal bridging impact.

SWA’s field review of this project found that the last course of brick under the shelf angle was cut to “fit” the pitch instead of being sized to a proper mortar joint. It resulted in excessive expansion and spalling of the bricks at the toe of the shelf angle and inadequate drainage of the area.

Another problem observed was improper shimming of the shelf angle. It allowed water to infiltrate and corrode the steel angle, which could not support the brick above. This condition is commonly referred to as “lipped brick” and can be caused by poor installation, inadequate mortar joints, condensation, or improper protection of the steel angle.

SWA’s engineering services review of this project included 3D thermal modeling to understand the impact of various design solutions for addressing masonry thermal bridging caused by shelf angles. Specifically, modeling focused on the influence of a stand-off shelf in an angle connector geometry, thermal properties, spacing of the connectors, and insulation thickness on the performance of the thermal break. This information will help SWA develop a more effective solution to address masonry thermal bridging in future projects.

 

Masonry support systems are horizontal ledges that transfer the load of brick or stone veneer buildings onto the main structure. They are typically located at the perimeter of a building and all openings, including doors, windows, and vents. The masonry supports are also designed to allow for differential movement between the brickwork and concrete frame by providing a space or gap at the supporting level that allows for movement.

Brick masonry is known to expand, while concrete tends to shrink. Provision for movement between the two materials is achieved by a system of vertical and horizontal expansion joints, shelf angles, adjustable veneer anchors, and concrete and steel reinforcement. Inadequate or improper mounting may lead to corrosion of embedded steel elements such as lintels, anchors, and ties, which can subsequently cause deflection cracks in the masonry veneer or structural distress in the concrete frame structure.

Typical failures of masonry support systems occur when the bracket angle is either fixed too tight or not tight enough. It can be due to a need for more detailing and specification of the required bolt size or better installation practices. It is common for builders to fix the masonry support as they go along rather than at an early stage in construction, and this can result in the bracket being skewed or incorrectly fitted.

The most common masonry support systems consist of continuous thin-angle supports, welded brackets, or individual bracket angle supports. The welded system is the most economical to design and supply. It consists of various sizes of stainless angle brackets, depending on the loading being fixed back to the structural frame at system centers. These are then loaded into the stands and adjusted. The system can be improved on-site by the use of shimming. However, this should only be used up to the maximum thickness of the outside diameter of the fixing bolt or 16mm, whichever is less.

AnconOptima masonry support systems include:

  • Laser-cut brackets.
  • Two-step angles with pre-marked fixing zones.
  • Locking wedges to ensure the correct contact.

The system is compatible with Ancon Thermal Breaks, which minimize heat loss through cold bridging and improve the U value of the wall assembly. The standard methods referenced, AnconOptima 10, 12, and 14, can support uncategorized masonry loads up to 10kN, 12kN, and 14kN per meter, respectively.

 

Masonry has several types of joints, and each performs a different function. Concave joints are the most common and provide excellent resistance to water penetration, whereas rodded or V-shaped mortar joints offer less protection. Struck or raked joints tend to degrade more rapidly, while beaded or extruded joint profiles produce an old-fashioned and formal look but may not be as durable as other types of joints.

Different joint styles also produce varying degrees of masonry weathering. A concave joint, which extends past the surface of the brick, typically sheds more moisture than any other type of joint and provides the best overall masonry weathering performance. On the other hand, the beaded or v-shaped joint does not extend far enough from the face of the brick to properly shed rain, resulting in a wall that collects water and can lead to structural and aesthetic problems.

Movement joints separate the masonry wall into segments, which minimizes cracking that occurs as dissimilar materials expand or shrink. In angled masonry walls, movement joints are usually provided in horizontal directions (as opposed to vertical) and must be spaced at least 0.375 inches apart. Considering their differing expansion tendencies, the spacing between the movement joints should be adjusted to allow for anticipated dimensional changes in the concrete frame and the brick veneer.

In addition to movement joints, a minimum of two expansion joints should be provided for angled masonry walls laid in running bond. These expansion joints are required to prevent the corners of the masonry units from contacting each other, which can cause shear and differential movement between the brick and concrete frame, resulting in random wall cracking.

All expansion and head joints should be finished using a tool rather than by hand raking, as this produces a more compact, clean, and resilient finish. The joints should be sprayed with water or a diluted masonry sealant before application of the adhesive to improve adhesion and minimize the potential for deterioration.

Moving Contractor

Safety Measures Taken by Residential Movers

When you’re moving, you want to ensure your belongings are safe and secure. Hiring a residential mover will help you accomplish this goal. A residential mover is an experienced team that specializes in moving homeowners. Moving Companies understand how to pack delicate furniture and protect one-of-a-kind items like glass pieces and antiques. They can also provide reliable transportation for these valuable belongings.

Moving ContractorMoving is a time-consuming process and can be expensive. You’ll need to factor in the cost of hiring movers, packing supplies, and any additional services you may require. Residential movers are often hired to move households and families into new homes, apartments, or condominiums. They can provide reliable transportation, gentle hands, and expert packing techniques for delicate items.

Generally, moving costs depend on the distance between your current home and your future location. It can also depend on the size of your home and how much packing and labor you need. Commercial movers typically haul different types of cargo than residential movers do. They usually haul large equipment, machinery, and office supplies for businesses. The cost of a residential move can range from relatively inexpensive to very costly depending on a number of factors. Some of the most important factors include:

Moving a home takes a lot of time and effort. The process starts months in advance of the move and includes:

  • Coordinating with friends and family.
  • Packing boxes.
  • Renting a truck.
  • Getting everything ready for the big day.

The amount of time it takes to complete a move depends on a variety of factors, including the number of items being moved and their location. For example, a four-bedroom house can take between eight and ten hours to complete.

In addition, a long-distance move can take longer than a local one. This is because movers will often stop along the way to rest and pick up other shipments. The best time to schedule your move is during the fall or winter, when movers are more available and rates are lower. However, demand for movers increases significantly during the summer months and prices can skyrocket.

Whether you choose to hire Residential Movers or do it yourself, there are some safety measures you should follow in order to ensure your move goes smoothly. From lifting heavy boxes to sanitizing and following COVID-19 restrictions, you should be aware of the risks associated with moving so that you can take the necessary precautions to avoid them.

While moving, make sure all hallways, paths, stairs, and outside areas are clear of any obstacles that could pose a hazard to your movement. This includes removing floor litter and clearing out areas that might otherwise impede movement, such as doorjambs and stairs where nails or other sharp objects may protrude.

Another safety measure that you should consider is wearing closed shoes. Instead of flimsy flip-flops or high heels, opt for sports shoes that provide excellent traction and anti-slip soles. This is especially important if you are moving in the winter.

Residential movers take many convenience measures to ensure that your move is easy and less stressful. This includes packing all your belongings in the most effective way possible so that they don’t shift during transport and that your items are well protected from any damage while being transported.

This is a great benefit as it will save you both time and fuel costs while making the process of moving a whole lot faster. It also helps to minimize the risk of any accidents that can occur while moving heavy furniture and boxes.

In addition to offering convenient services, a good moving company will also provide insurance for your belongings, preventing any damage during the journey. This is especially helpful if you have a lot of expensive or delicate belongings that can be easily damaged during the journey.

Experienced movers can help you when you’re moving from one location to another. They’ll know how to pack and unpack your stuff so that you can have the smoothest move possible. In addition, they’ll be able to ensure that you’re completely satisfied with their service.

Multi-level Marketing

Multi-level Marketing is a Viable Business Option.

Multi-level marketing is a viable business model. This question is more pertinent than ever. The industry is booming. While some companies may try to resell products to increase profits, MLMs sell directly to consumers. However, this model has its faults. Check out Vidadivina to learn how multi-level marketing can be a viable business option.Multi-level Marketing

Network marketing’s high attrition rate is one of its biggest problems. This is the number of people who sign up for a network marketing company but don’t finish it. This high attrition rate is a common reason why companies rely on it. They believe that the people they recruit will be more likely to stay. Network marketing should be avoided. It can be a viable business model, even if you don’t get rich from it.

Building a strong marketing team is key to building a multi-level marketing company. MLM companies make the common mistake of not investing in genuine enthusiasm. This type of recruit will invariably cut corners and deceive other people, leading to a poor reputation for the company. You must spend time building your marketing team and finding people who truly care about the company’s products and services.

MLM companies often require that you purchase marketing materials, travel expenses and make periodic purchases of products and services. These activities are usually paid for with credit cards. It is worth noting that MLM companies often require you to spend time on them. MLM companies also often offer bonuses to those who opt-out. The benefits of network marketing outweigh any drawbacks.

Multi-level marketing is often mistaken for a pyramid scheme. Although Mary Kay and Lia Sophia are well-known, many MLMs can be described as investment schemes. This business can be started earning income in a matter of months with a minimum investment of $10K. You should be able to invest in a quality company if you are serious about multi-level marketing and making money.

You will typically work remotely as a sales representative. You buy inventory and then sell it at parties. You are a sales representative and own your business. You also earn a commission for the sales of your recruits. Your recruits’ sales volume will also give you a commission split. Many people join MLMs due to their passion for the products or because they were encouraged by a friend or colleague.

Multi-level marketing can be a viable business model despite the many challenges. Although the pyramid scheme is a well-established business model, it requires patience, persistence, and a marketing strategy. It can also be leveraged word-of-mouth advertising thanks to the growing gig economy and freelancers. Multi-level marketing companies are still considered to be risky. Make sure you thoroughly research the company.

Multi-level marketing may not be for everyone. However, there are some scams. You need to understand the risks, compensation, and commissions associated with any business model that you are considering. Herbalife Nutrition is an example of a multi-level marketing company. Herbalife is a publicly-traded company that sells nutritional products. It is represented by over 70.000 distributors around the world.

Multi-level marketing can make it possible for many people to make a decent income, but the failure rate is high. A study done by the AARP found that only one-fourth earned profit from their business. Worse, 53% of participants failed to make five-thousand-dollar. The company also offers very little support for lower-tier distributors. They may not be as efficient in their sales efforts.

Many MLM companies have been ruled legitimate by the FTC. However, there have been some lawsuits. William Ackman, in fact, exposed MLM as a pyramid scheme. MLM companies still operate despite these legal challenges. What are the risks associated with multi-level marketing? These risks will be discussed and you’ll learn why this model is dangerous. Are you thinking about a multi-level marketing opportunity?

Multi-level marketing is hot as we all know. Multi-level marketing is one of the fastest-growing industries in the world. These companies have been around for many decades and are poised to experience explosive growth. Carl Rehnborg founded the industry in the 1930s. California Vitamin Company was founded by Carl Rehnborg, who studied the health benefits of Chinese dietary supplements. Later, he renamed the company Nutrilite and restructured it as an MLM.
