When is a dead (vertical) shore used?

To support two parallel walls across a narrow gap

To pull a leaning wall back with inclined posts

To give a working platform for masons

What is the function of the needle in a dead shore?

A horizontal beam passing through the wall at the top that carries the load onto the posts

A diagonal member that stops sideways movement

A base plate spreading load on the ground

Why are the vertical posts placed on a sole plate?

To spread the load over the ground at the bottom

Which sequence is correct for erecting a dead shore?

Objectives of shoring; dead shore

Short answer

Shoring objectives are to prevent collapse of weak walls, support adjoining buildings during demolition or excavation, carry loads during alterations, and ensure safety. Dead shore uses vertical posts on a sole plate with a horizontal needle passing through the wall to support floors and roofs above when a lower wall is removed or altered, transferring vertical loads to ground.

What are the objectives of shoring? Discuss in brief about the dead shore with necessary figures.

Objectives of shoring

To prevent collapse of a weak, leaning or cracked wall.
To support adjoining buildings during demolition or excavation.
To support the structure above while the lower part is altered or underpinned.
To carry loads temporarily during repair or extension.
To give safety to people and property.

Dead shore

Dead (vertical) shore: used to support the floors and roofs above when a wall is removed or an opening is made at lower storeys, or when the lower wall is repaired. It transfers the vertical load to the ground.

It consists of vertical posts (dead shores) on a sole plate at the bottom, a needle (horizontal beam) passing through the wall at the top, braces, cleats and wedges to take the weight.

   wall| | post | |
       |_|______|_|
       sole plate

Parts: needle, vertical posts, braces, cleats, wedges, head plate and sole plate. Procedure: holes are made in the wall at floor level for needles, the needle is fixed and wedged, posts are put under the needle on a sole plate, wedges are driven to take load, and then braces are fixed. After this, the lower wall can be removed or altered safely. Use: when the wall below is removed or altered, or an opening is made, in multi-storey buildings.
