Load Bearing Solutions Load bearing structures make use of the axial capacity of the Metsec SFS studs, with studs designed as a series of columns to provide complete load bearing wall panels.
High bay walling solutions High bay walls are similar to infill walls, except they are used internally to provide high separating walls for factory units or atriums. Technical Details Full details.

It is the plan to which all trades people refer. It is a top view horizontal section cut through the house about 1. The purpose of the floor plan is to show the location and dimensions of exterior and interior walls, windows, doors, major appliances, cabinets, fireplaces, and other fixed features in the house. Upon completion of the preliminary sketches and proposal, a — scale floor plan is drawn which is considerably more detailed than previous floor plans.
Windows and doors are coded. All exterior walls, interior walls, windows, and doors are dimensioned. To conserve time and paper, the electrical plan is sometimes included on the floor plan. You will have one drawing for the floor plan, and one for the electrical. When applicable, related structures such as freestanding garages or swimming pools are shown on the floor plan C. Walls should be drawn accurately. Exterior walls can be either 15cm or 20cm thick, and interior walls should be 15cm thick.
Fireplaces or stairs require only basic size and location information on the floor plan. Special details will be included in the plans for these features. Floor plans should include several dimensions. All students will draw a basement foundation. The weight of a house is supported by footings extended into the ground.
These footings are concrete with steel reinforcing to reduce cracking. The footings must extend below the frost line. All this information should be given in the foundation plan A.
The foundation plan is a plan view in sections, which shows the location and size of footings, piers, columns, foundation walls, and supporting beams. It is usually drawn after the floor plan and elevations have been roughed out. A foundation plan contains: Footings hidden lines Foundation walls Piers and columns Dwarf walls low walls to retain excavation or an embankment Partition walls, doors, and bath fixtures if the house has a basement Openings in the foundation walls doors, windows, and vents Beams and pilasters Direction, size, spacing of floor joists, drains, and sump if required Details of the foundation and footing construction.
Complete dimensions and notes scale of the drawing. But there are also good sources of connector information from the manufacturers of framing connectors right in the catalog or in installation sheets , as well as in various engineering and carpentry texts.
Watch out : the number of holes in a typical joist hanger is a clue to the number of nails that the manufacturer expected you to use to make a secure connection. Our pocket-knife is pointing to missing framing nails in the 2x4-sized framing-connector above. It is not necessary to use steel joist hangers if the joist is properly toe-nailed from either side into the ledger board, provided that the proper size and number of nails are used.
Our illustration left, adapted from a Double-Shear stamping on a steel joist hanger explains why toe-nailed lumber connections can be very strong. Use of toe-nailing, or angled opposed framing nails Double-Shear in Simpson Strong-Tie's patented[10] joist hanger such as the item adapted above , can permit the use of fewer total nails in a wood frame construction.
Our photographs illustrate use of a Simpson Strong Tie connector specified for use on a range of I-Joist sizes. As we illustrate its installation here, the connector is nailed over the side of the I-Joist, then to the wall top plate, then to the wall stud below, forming a very strong connector where these I-Joists were used as roof supports.
Our first photograph left shows ;that we installed the specified number of joist-hanger nails minimum of five through the connector end and into the top of the I-Joist. Our two photos below illustrate the required position and number of nails for the extended connector strap as it passes over the wall top plate and along the side of the I-Joist where it was nailed to the top chord tie and to the block inserted at the end of the I-Joist below left.
An additional 4 nails into the top plate and at least 3 depending on how the strap aligns into the wall stud give us 7 fasteners into the structural wall below.
If additional nails are needed into the wall stud the strap can be bent around the stud side for that purchase point.
The layout required some planning and thought to assure that the I-joists were placed over wall studs in a location to permit the strapping of I-Joist to both the wall top plate and the wall stud using a single strap. If your plans don't work out quite so precisely you will still be OK but if your I-Joist connector straps don't line up to tie all three wall components together at once,.
At left we illustrate installation of the same utility framing connector strap at the opposite side of the same building as the structure above. In this location the lower ends of the framing connectors were nailed from the exterior of the building, through the OSB structural sheathing and into wall studs below. Above we illustrated using steel framing connectors to tie I-Joists to a wall top plate and stud for the case of I-joists that run on top of the building walls.
Simpson Strong Tie and other manufacturers provide straight for floors or angled I-Joist hangers for framing I-Joists between building walls such as for installation of a floor, a flat roof, or a roof with no overhang. Where both sides of the joint are accessible, bolts offer the strongest connections. After drilling, saturate the pilot hole with wood preservative. It is also important that at least half the length of the lag is threaded into solid wood.
Instead, the lag screw should go through the 2x and be threaded into the thicker 4x4. Use a large washer under the head, and re tighten after the first year in case materials have shrunk. Our photo above left illustrates use of a lag bolt to connect the deck ledger to the building structure by bolting to the rim joist. Trista Johnson, I agree that that use of a joist hanger looks pretty unusual, as does a sill plate that's canti-levered out over a foundation wall. What is that joist hanger going to carry?
Who designed this? When a new home is being constructed there must be a set of architectural plans, including a framing plan, provided by the architect or engineer who designed the project. You might start by reviewing this detail with that design expert; that ought to be a more reliable approach than is afforded by our very limited view here and our complete lack of any information about the building and its framing plan.
But we don't know what other structural support the builder has in mind nor what is the purpose of this hanger. We are having a house build, and notice this joist hanger was not secured to the ledger board, but a extra piece of wood nailed to it without any support under it. The owner of the company says it looks perfectly fine to him and does not think it will cause any issues our concern, sagging.
We have a new Project Manger with 20 years of framing experience who just started with the company yesterday, and the owner said he will have him look at it. If the Project Manger says it is ok, they do not plan to make any changes. Any advise? Kim you will perhaps best be served by asking a welder to weld-on appropriate steel connecting brackets, perhaps site-fabricated, to the tops of your metal columns and to connect to appropriate horizontal joists or ties as well as to the top plate that will support your roof.
We have 5cm metal posts that we want to create a wooden framed roof to. AWC has also developed recommended amendments to span tables for new construction designed in accordance with ICC model building codes. For more information, visit www. Wood Structural Design Data, Edition, provides information related to design of typical wood structural members. These data are augmented by reference to the National Design Specification for Wood Construction, particularly on the subject of design stresses.
