So for example, if a 1/2" board is being screwed onto the concrete, a 1-3/4" to 2" concrete screw should be used. deck screw: Similar to drywall screw, except that it has improved corrosion resistance and is generally supplied in a larger gauge. Most deck screws have a type-17 (auger type) thread-cutting tip for installation into decking ...
Gypsum concrete is lightweight and fire-resistant. A 1.5-inch slab of gypsum concrete weighs 13 pounds per square foot versus 18 pounds per square foot for regular concrete. [10] Even though gypsum concrete weighs less, it still has the same compressive strength as regular concrete, based on its application as underlayment or top coat flooring ...
Tapcon screws are a popular anchor that stands for self tapping (self threading) concrete screw. Larger diameter screws are referred to as LDT's. This type of fastener requires a pre-drilled hole—using a Tapcon drillbit—and are then screwed into the hole using a standard hex or phillips bit. These screws are often blue, white, or stainless ...
Special wall fasteners (screw wall plug anchors) designed for autoclaved aerated concrete including gypsum board and plaster tiles are available at a higher cost than standard expandable wall plugs, including special safety-relevant anchors for high load bearing; [58] [59] [60] It is recommended that fixing holes be drilled using HSS drill bits ...
Concrete roofing is composed of concrete reinforced with fibers of some sort. Structural concrete can also be used for flat roof constructions. There are three main categories, precast/prestressed, cast-in-place and shell. There are many types of precast/prestressed concrete roofing. The following are the most common types. [8]
Drywall: a specialty blued-steel nail with a thin broad head used to fasten gypsum wallboard to wooden framing members Finish : a wire nail that has a head only slightly larger than the shank; can be easily concealed by countersinking the nail slightly below the finished surface with a nail-set and filling the resulting void with a filler ...
ICF decking can also be designed in conjunction with ICF walls to form a continuous monolithic structure joined together by rebar. ICF deck roofs are popular in storm-areas, [14] but it is harder to build complex roof shapes and concrete can be poured only up to a point on angled surfaces, often 7:12 maximum pitch. [15]
