Fire Cut
In the construction of masonry Masonry is the craft of building a structure with brick, stone, or similar material, including mortar plastering which are often laid in, bound, and pasted together by mortar (masonry), mortar.

Sudbury, MA: National Fire Protection Association :, 2007. Print. or fireman's cut is a diagonal chamfer of the end of a joist or beam where it enters a masonry wall. If the joist burns through somewhere along its length, damage to the wall is prevented as the fire cut allows the joist to fail and still leave the masonry wall standing. Without firecut joists, if the burnt joists fail and rotate the unchamferred ends of the joists as they deflect downwards, this would damage the masonry wall at the connection point and possibly pull the wall inwards.

Masonry
Masonry is the craft of building a structure with brick, stone, or similar material, including mortar plastering which are often laid in, bound, and pasted together by mortar (masonry), mortar. The term ''masonry'' can also refer to the building units (stone, brick, etc.) themselves. The common materials of masonry construction are bricks and building stone, rock (geology), rocks such as marble, granite, and limestone, cast stone, concrete masonry unit, concrete blocks, glass brick, glass blocks, and adobe. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. These are both classified as construction worker, construction trades. History Masonry is one of the oldest building crafts in the world. The constructio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chamfer
A chamfer ( ) is a transitional edge between two faces of an object. Sometimes defined as a form of bevel, it is often created at a 45° angle between two adjoining right-angled faces. Chamfers are frequently used in machining, carpentry, furniture, concrete formwork, mirrors, and to facilitate assembly of many mechanical engineering designs. Terminology In materials and manufacturing, a ''chamfer'' is used to "ease" otherwise sharp edges, both for safety and to prevent damage to the edges; it may also be a primarily decorative feature. In general terms it may be regarded as a type of ''bevel'', and the terms are often used interchangeably. However, in machining, only the term chamfer is used for the specific technique, practice, and result. In carpentry, a lark's tongue is a chamfer which ends short of the end of a piece in a gradual outward curve, leaving the remainder of the edge as a right angle. Chamfers may be formed in either inside or outside adjoining faces of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joist
A joist is a horizontal structural member used in Framing (construction), framing to span an open space, often between Beam (structure), beams that subsequently transfer loads to vertical members. When incorporated into a floor framing system, joists serve to provide stiffness to the subfloor sheathing, allowing it to function as a horizontal Diaphragm (structural system), diaphragm. Joists are often doubled or tripled, placed side by side, where conditions warrant, such as where wall partitions require support. Joists are either made of wood, engineered wood, or steel, each of which has unique characteristics. Typically, wood joists have the Cross section (geometry), cross section of a Plank (wood), plank with the longer faces positioned vertically. However, engineered wood joists may have a cross section resembling the Roman capital letter ""; these joists are referred to as I-joist, -joists. Steel joists can take on various shapes, resembling the Roman capital letters "C", "", " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
