Red Seal Carpenter Practice Exam

In the snap tie system of forming, the wedges should be placed at a slight angle to increase their bearing on the structural forming members. What else should be done?

1. The wedges should be hammered as tight as possible and tacked with two duplex nails to prevent dislodging.

2. They should be nailed with two duplex nails and the large hole up to prevent dislodging and make stripping easier.

3. They should be nailed with two duplex nails and the large hole down to prevent dislodging and make stripping easier.

4. They should be hammered snug and tacked with two duplex nails to prevent dislodging.

The correct answer is: They should be nailed with two duplex nails and the large hole up to prevent dislodging and make stripping easier.

In the snap tie system of forming, the wedges should always be placed at a slight angle to increase their bearing on the structural forming members. This helps to ensure that the forms stay in place while the concrete is being poured. Additionally, the wedges should be nailed with two duplex nails in order to secure them properly. Option A is incorrect because hammering the wedges as tight as possible can potentially crack the wood and cause dislodging. Option C is also incorrect because placing the large hole down would not provide enough support and can lead to dislodging. Option D is incorrect because without nailing, the wedges may not stay in place and can cause dislodging. That leaves us with option B, which advises to use two duplex nails to secure the wedges with the large hole up. This will not only prevent dislodging but also make the stripping process easier.
