Before answering the question, it would be easier for you to understand the same when you have a clear idea about what a joist is. Joists are structural members used in construction operations. These are horizontal structures that are used in framing works spanning in an open space and is often installed in between beams for the subsequent transfer of load to vertical members.
These supporting structures can also be applied in flooring operations. Cases where stiffness to the subfloor sheathing is required, joists can be skilfully placed at certain points so that it can act as a horizontal diaphragm. Joists can also be used in supporting wall partitions as well.
Advantages of Using Timber to Masonry Joist Hangers
Timber to masonry joist hangers is used in the meeting points of masonry walls and timber floors. When one uses masonry joist hangers, they cut the need for making holes in the mason walls. It helps in keeping the construction costs bearable without compromising structural integrity.
Following are some advantages of using timber to masonry joist hangers:
- Helps in supporting beams and connecting masonry walls to timber
- They can easily be attached to both brick and blockwork that has been recently erected
- Comes in handy during labour extensive projects and renovation works
- Using joists helps in eliminating the need for building around support beams and cutting holes in brickwork facing
- Ideal for use in making timber to timber connections
Types of Timber to Masonry Joist Hangers
Masonry Joist Hangers are available in various types. Some of them are discussed below:
- Welded masonry joist hanger
- Single piece joist hanger,
- Straddle welded joist hanger
- Welded masonry return joist hanger,
- Return joist hanger (with adjustable lock plates)
Why Use Heavy Timber to Masonry Joist Hangers?
Joists with standard dimensions have limitations when it comes to loading bearing capabilities. It is due to the fact that framed lumber can only bear a specified amount of load when compared to engineered wood.
Engineered wood joists like I-joists are scientifically proven to gain their strength from the depth of the same. On top of that, engineered wood joists are made from high-quality lumber that has impressive tensile strength. When it comes to joists, “deeper is cheaper!” It means that buying expensive joists is the way of the wise since in the long run, it is a cost-effective way to keep the structure intact for years to come. Also, going for heavy timber to masonry joist hangers ensures that fewer joists are needed in whole construction project.
Joist hangers should exhibit the qualities and capabilities of supporting huge loads over a long period without giving in. Several countries around the world keep up certain standards and codes with which the joists should be at par with in terms of structural integrity.
It is critical to carefully consider the overall depth and cross-section of a joist before installing the same in critical points of a structure (especially in flooring, walls, and ceilings.) Failing to do so will not only endanger the project but also shorten the life of the structure.
