USING DRYWALL CLIPS TO SECURE. THE ENDS OF DRYWALL SHEETS

Corner details

If you provided backing or deadwood while building interior walls (see chapter 4) and installing roof trusses (see chapter 5), you’ll be able to drive nails or screws along the walls to fasten drywall panels. But if solid backing material for drywall was not nailed to the tops of parallel walls or in the corners where walls intersect, metal drywall clips can be used instead. See the illustration at right for instructions on using these clips. Unlike a dry – wall corner secured with nails or screws, a cor­ner secured with clips can be more resistant to cracking when the framing material moves in response to temperature fluctuations...

Enesti

Posted by on 23/ 11/ 15

The Enesti, or NST (not so tiny), contains two bedrooms, one-and a-half baths, a fireplace, a dining nook, ample storage and a full kitchen that includes a washer/ dryer beneath the counter. A third bedroom is also available.

STRAIGHT COUNTER, NO SINK

Posted by on 23/ 11/ 15

The simplest surface to lay out is a straight counter with no sink because it has only one con­trol line. Begin by using a framing square and a story pole to survey the countertop.

“Counter Layout,” on p. 398, assumes that the counter edges are finished with V-cap trim, a

I Counter Layout

A straight counter needs only one layout control line to indicate the first tile joint back from the edge.

common choice, and tile joints are Vs in. wide. Place several V-caps along the counter edge; then measure back from the edge & in. from each cap to mark the middle of the first grout joint. Snap a chalkline through these marks to establish a con­trol line. Because the front edge is the counter’s focal point, you’ll place full field tiles next to the row of V-caps.

Using your story pole, measu...

Basic probability rules for system reliability

Posted by on 23/ 11/ 15

The solution approaches to system reliability problems can be classified broadly into failure-modes approach and survival-modes approach (Bennett and Ang, 1983). The failure-modes approach is based on identification of all possible fail­ure modes for the system, whereas the survival-modes approach is based on the all possible modes of operation under which the system will be operational. The two approaches are complementary. Depending on the operational char­acteristics and configuration of the system, a proper choice of one of the two approaches often can lead to significant reduction in efforts needed for the re­liability computation.

Thinset Adhesive

Posted by on 23/ 11/ 15

Once you’ve snapped layout lines and vacu­umed the setting bed one last time, use the straight edge of a notched trowel to spread thinset adhesive. Then, using the notched edge of the trowel, comb ridges into the adhesive.

As you apply and comb adhesive, try to stop just short of the layout lines, so you don’t bury them under adhesive.

Installing a Floor

Using a framing square and a tape measure, check to be sure the room’s corners are square and parallel. Make a quick sketch of the room, showing which way corners diverge. Or sketch this directly onto the setting bed.

ESTIMATING TILE

Posted by on 23/ 11/ 15

If you’re installing a popular tile that a local sup­plier has in stock, wait till you’ve installed the set­ting bed before estimating tiles. If you order too many, most local suppliers will take back extras, as long as they aren’t damaged or returned too long after purchase. Ordering tiles is not compli­cated unless surfaces to be tiled have a lot of jogs, recesses, odd angles, and obstacles. Using a tape measure and a pad of graph paper, calculate the square footage of the surface to be tiled and add 8 percent to 10 percent for waste, damage, and future repairs.

Handmade or exotic tiles are another story.
Because they’re expensive and must be ordered

MANAGING THE FRAMING START

Posted by on 23/ 11/ 15

Certain activities must take place before you begin framing. The dimensions and level of the foundation and slab need to be checked. If they are not perfectly level (which is not unusual), you must determine how far from correct they are, whether they are within tolerances, and what types of adjustments you must make. It is important that the dimensions are accurate, and the building is square before you start. Note, too, that the cabinets, floor covering, drywall, roof trusses or rafters, and much more depend on the measurements being accurate and square.

The four steps to getting started, covered in this chapter, are:

1. Checking the exterior wall dimensions

2. Checking the reference lines for square

3. Adjusting the reference lines to correct dimensions and square

I have added a small bump-out in the loft. Once again, the loft is not counted in the square footage listed but contains ample space. A downstairs bedroom is also aval – able.

Fasten according to code

Posted by on 23/ 11/ 15

Hold screws or nails back about 5/s in. from the edges of the panel, and drive them in straight so you don’t break the paper. Follow the fastening schedule for drywall that applies in your area. When ceiling joists are 24 in. o. c., nails or screws are usually driven every 8 in. along the edge of the panel and every 12 in. in the middle.

Some builders use drywall panel adhesive when attaching sheets of drywall. The adhesive is applied with a caulking gun, just like caulk or sealant. With panel adhesive, the need for screws
or nails is greatly reduced. Don’t use adhesive over a poly vapor barrier or kraft paper-faced insulation; it’s designed to affix drywall to a wood surface. Follow the application and instal­lation instructions on the label.

Test Results

Posted by on 23/ 11/ 15

A comparison of macrotexture depths of courses executed with various asphalt mix­tures has been presented in an Australian paper (Oliver, 2001):

• Surface dressing (greater than 10 mm)—macrotexture less than 1.5 mm

• AC (greater than 10 mm)—macrotexture 0.4 to 0.8 mm

• Porous asphalt—macrotexture less than 1.2 mm

• SMA—macrotexture less than 0.7 mm

• Slurry seal—macrotexture 0.4-0.8 mm

• Cement concrete (brushed)—macrotexture 0.2-0.7 mm

Changes in some SMA characteristics occurring over time have been indicated in various investigations. In the United Kingdom, Richardson (1997) described changes in the SMA macrotexture during the months following the construction of a course. The SMA macrotexture, just after placement, was initially at a level of 1.5-1.6 mm...
