Construction, unless otherwise indicated. However, a B1 is not a full-strength connection and therefore will be unsuitable for some applications. Framing Standard: Comply with AF&PAs Details for Conventional Wood Frame. Therefore, a B1 connection is sometimes used as an alternative. This can be an issue when space is limited.
Regular splice connections (A1 & A2) can add as much as 100mm to the depth of a beam, with the additional plates and bolts. Furnish miscellaneous accessories including splice plates and bolts required by joist. If your beam flanges and web are 12mm thick then the plates used for the splice connection should also be 12mm thick. reflected ceiling plans and/or building sections and details as. These bolts are expensive, so if you are told they are necessary it might be a good idea to talk to your Structural Engineer to see if there is a possibility of a redesign enable you to use the normal, more cost effective, 8.8 grade bolts.Īs a general rule of thumb the flat plates used in splice connections should be the same thickness as the flange or web they are affixed to. In some cases, HSFG (High Strength Friction Grip) bolts are required, in which case the beam ends and the splice plates must not be primed. Your structural engineer will have specified which connection is best for your structure. The flat plates are connected in different ways (listed below) depending on the requirements. Special detailing can be utilized in cases where distances between outer rows of bolts exceed the limits in 2015 NDS 12.5.1.3, such as the use of multiple splice plates or a single splice plate with slotted holes to allow shrinkage. Splice connections are flat plates of steel fixed to the beam to hold the joint/splice secure. This configuration can also be used when access is a concern. Extruded Aluminum Gravel Stop and Fascia Sump: Complete system including fascia, water dam, splice plates, corners, and intersections, and all other.
Instead the beam is cut into two or possibly even three sections and then fixed together using a splice connection in situ. 12.5.1.3, such as the use of multiple splice plates or a single splice plate with slotted holes to allow shrinkage. The innovative mounting systems for the ceramic ventilated façade are simple, with hidden fastening and without the need to make incisions in the plate, providing optimal fixing. Splices are a cut in a beam usually needed when a beam is too long or heavy to be installed in one piece.
