slip joint

Slip joints are used when the main problem is a large axial movement.

Most pocket knives for light duty are slip joints.

The syndrome is also linked to slipping joints.

Examples of continuous slip joints are given below.

A slip joint is a mechanical construction allowing extension and compression in a linear structure.

Slip joints are common under conditions where temperature changes can cause expansion and contraction that may overstress a structure.

A prop-shaft assembly consists of a propeller shaft, a slip joint and one or more universal joints.

Slip joints in large structures are used to allow independent motion of large components while enabling them to be joined in some way.

Pipe supports often are slip joints to allow for the thermal expansion or contraction of the pipe relative to the support.

Slip joints can also be non-telescoping, such as the joints on some older wooden surveyor's levelling rods.

Slip joints can be designed to allow continuous relative motion of two components or it can allow an adjustment from one temporarily fixed position to another.

Besides gutter sections, you will need drop outlets, slip joints, end caps, brackets and downspouts, the vertical pipes leading from the gutters to the ground.

The transbay tube terminates at an under-bay slip joint near the Embarcadero Station in San Francisco.

These factors have resulted in the slip joint being designed too short to ensure survival of the tube under possible (perhaps even likely) large earthquakes in the region.

To correct this deficiency the slip joint must be extended to allow for additional movement, a modification expected to be both expensive and technically and logistically difficult.

Aluminum rods may adjust length by telescoping sections inside each other, while wooden rod sections are attached to each other with sliding connections or slip joints.

To avoid overstressing the tube due to differential movements at each end, a sliding slip joint was included at the San Francisco terminus under the landmark Ferry Building.

A slip joint was built into the dam to accommodate 1-2 metres of potential ground movement, and a large amount of slurry cement was pumped into the rock to stop water leaks.

Extensive reconstruction work at the Hayward Fault crossing includes a multi-sectioned tunnel structure to allow shear without collapse, this is to contain a section of water pipe with ball joints and a slip joint.

Slip joints are sometimes found in tubular structures such as piping, but are generally avoided for this application due to requirements for sealing against leakage, instead using either a large loop that is allowed to flex or a semi-rigid bellows.

Log houses which settle require slip joints over all window and door openings, adjustable jacks under vertical elements (such as columns and staircases) which must periodically be adjusted as the building settles, allowances in plumbing, wiring, and ducting runs, and fasteners for the walls themselves to prevent uplift.

Gordon Bunshaft, then chief designer of Skidmore, Owings and Merrill, was originally hired by the consortium; his proposal called for exterior structural supports for the main office tower, which then necessitated piston-like slip joints at the roof level to deal with weather related expansion and contraction of the structure.
