Any of various U-shaped metal brackets for supporting the end of a beam, joist, purlin, or truss at a girder or wall The supported member transfers its reaction to the hanger through bearing, but load transfer to the supporting member is through shear in the special nails securing the hanger.
A U-shaped metal bracket for anchoring a timber beam to a concrete support.
A U-shaped metal bracket for securing a timber beam to a supporting post. Also called column cap.
A U-shaped metal bracker for supporting and anchoring timber post to its base or foundation. Also called COLUMN BASE.
A cylindrical pin fitting snugly into holes in two adjacent pieces to prevent their slipping or to align them. Also called DOWEL PIN.
A sheet metal plate punched to produce a closely spaced grid of protruding teeth, used as splice plate in the manufacture of light wood trusses.
A flat or singly curved grid of spikes for joining heavy timbers., held in place by a single bolt. The resulting joint is resistant to loosening due to vibration, impact, and reversible lateral loads.
Any of various sheet-metal connectors for joining light wood framing members, using special nails that are loaded laterally rather than in withdrawal.
A framing anchor for tying a rafter or truss to a wall plate and securing it against lateral and uplifting wind and seismic forces. Also called HURRICANE TIE.
A metal tie strap for securing the joists of a floor or roof diaphragm to a concrete masonry wall in order to transmit lateral wind or seismic loads.
A metal tie strap for restraining a floor of a light wood frame structure against uplifting wind or seismic forces.
A framing anchor for securing a sill plate to a concrete slab or foundation wall.
A metal device for restraining a wood frame structure against uplifting wind or seismic forces, consisting of stiffened steel angle bolted to a wall stud and secured by a threaded rod to a concrete foundation.
A metal ring, plate, or grid for transferring shear between the faces of two timber members, used with a single bolt that serves to restrain and clamp the assembly together. Timber connectors are more efficient than bolts or lag screws used alone since they enlarge the area of wood over which a load is disturbed.
A timber connector consisting of a round plate of malleable iron inserted into a corresponding groove, lush with the face of a timber, and held in place by a single bolt. Shear plates are used in back-to-back pairs to develop shear resistance in demountable wood-to-wood connections, or singly in a wood-to-metal connection.
A timber connector consisting of a metal ring inserted into corresponding grooves cut into the faces of the joining members and held in place by a single bolt. The tongue-and-groove spilt in the ring permits it to deform slightly under loading and maintain bearing at all surfaces, while the beveled cross section eases insertion and ensures a tight-fitting joint after the ring is fully seated in the grooves.
To unite two pieces of metal by applying any of various, nonferrous solders, usually in a tin-lead alloy at a temp. below 800
Any of various fusible alloys applied in a molten state to the joint between two metal parts to unite them without heating the parts to the melting point. The molten solder flows into a joint by capillary attraction.
To unite two pieces of metal by applying any of various,nonferrous solders, usually a copper-zinc alloy, at a temperature above 800
To unite or fuse two pieces of metal by heating and allowing the metals to flow together, sometimes with pressure and the addition of an intermediate or filler metal.
Any of a group of welding processes utilizing the heat produced by the combustion of an oxygen and fuel gas, such as acetylene.
Any of a group of welding processes utilizing the hear of an arc between an electrode and the base metal.
A sustained luminous discharge of electricity across a gap in a circuit or between two electrodes. Also called ELECTRIC ARC.
Shielded metal arc welding
A method of arc welding using a consumable metal electrode that releases an inert gas to form a shield around the arc. This shield protects the weld area from oxygen and nitrogen in the air that would cause rapid oxidation of the liquid metal.
A continuous deposit of fused metal. Also called WELD BEAD.
The principal metal to be welded, brazed, soldered or cut as distinguished from filler metal.
The metal that is added during a welding, brazing or soldering process having a melting point, either approximately the same as or below that of the metals being welded.
Inert gas shielded arc welding
A method of arc welding in which the weld area is shielded by the continuous flow of an inert gas from an external source., the filler metal being supplied by a consumable metal electrode or by a separate welding rod.
A wire or rod of filler metal used in gas-welding and brazing processes, and in those arc-welding processes in which the electrode does not furnish the filler metal.
Flux-cored arc welding
A method of arc welding using a tubular steel electrode containing a core of vaporizing flux that forms a gaseous shield around the weld area.
A substance, such as rosin, applied to remove oxides from and prevent further oxidation of metal surfaces to bejoined by welding, brazing or soldering.
Submerged arc welding
A method of arc welding in which the weld area is shielded by a blanket of fusible, granular metal that melts to form a layer of protective slag. The filler metal may be supplied by a consumable electrode or by a separate welding rod.
A weld made by burning a hole in a piece of sheet metal and filling with a small pool of molten metal.
A weld made along the seams of two overlapping pieces of metal.
The junction between the base metal and the face of a weld.
The point at which the back or bottom of a weld meets the base metal.
The distance from the root of a weld to the face of the base metal.
A weld with a triangular cross section joining two surfaces that meet in an interior right angle.
A weld between two pieces of metal butted together.
A butt weld having depth less than the thickness of the smaller of the two members being joined.
A butt weld having a depth equal to the thickness of the smaller of the two members being joined.
Any of a group of welding processes utilizing the heat generated by resistance to the passage of electric current.
A weld made in a preformed indentation between two abutting pieces of metal.
A groove weld in which the edge of each abutting member is beveled from both sides.
A groove weld in which the edge of each abutting member is beveled from the same side.
A groove weld in which the edge of one abutting member is beveled from both sides.
A groove weld in which the edge of one abutting member is beveled from one side.
A metal pin having a head at one end, used for uniting two or more plates by passing the shank through a hole in each piece and hammering down the plain end to form a second head.
A round, tapering piece of metal for enlarging or aligning holes to receive rivets or bolts. Also called DRIFTPIN.
A drift for bringing holes in line to receive a rivet or bolt.
A tool for receiving and holding the head of a rivet while the other end is being headed.
A pneumatic hammer used with a rivet set to form the second head of a rivet.
A tool for shaping the second head of a rivet.
A rivet for a joint accessible from one side only, having an explosive filled shank that is detonated by striking the head with a hammer to expand the shank on the far side of the hole.
