Raking shores[ edit ]
in this method, inclined members called rakers are used to give temporary lateral support to an unsafe wall. One or more timbers slope between the face of the structure to be supported and the ground. The most effective support is given if the raker meets the wall at an angle of 60 to 70 degrees.
A wall-plate is typically used to increase the area of support. Foundations[ edit ]
shoring
is commonly used when installing the foundation of a building. A shoring system such as piles and lagging or shotcrete will support the surrounding loads until the underground levels of the building are constructed.
While you’re searching for the best type of shoring to use on your construction site , there are several factors for you to consider. These factors include: soil conditions – different shoring methods should be used depending on the type of soil you have on your construction site. Make sure you select the shoring method that provides optimal support. Proximity to other structures – if there are any structures nearby, there are likely some restrictions on open excavation. In this scenario, you should consider alternative shoring techniques like raking shoring or secant pile shoring. Environmental factors – the type of shoring you select depends on whether conditions are wet or dry.
What is Dead Shoring?
Dead shoring is also called vertical shoring. It can be defined as the type of shoring that is mainly used to provide support to the walls, roofs, floors, etc. , particularly when the lower part of a wall has been removed to provide an additional opening in the wall or even to rebuild a defective load-bearing wall in a structure. The shores used for such purposes are known as the dead shores. The dead shores consist management of posts and beams. These are necessary for providing support to the weight of the overall structure and transferring the weight to the ground lying underneath the foundation.
The types of shoring are as follows. Raking shores or inclined shores flying shores or horizontal shores dead shores or vertical shores also read: what is formwork in construction || 7 types of formwork used
wall plate: 23cm by 5cm to 23cm by 76 cm. Fixes to the structure through the use of hooks. 10cm by 76cm needles assist in securing. Wooden cleats strengthen the needles used to secure the shoring. When more than one raker is necessary they are bound together by hoops or braces that are 25cm by 15cm. Flying/horizontal shoring this type of shoring is implemented when there are two structures, one of which can be subject to damage while the other is under repair. Consists of wall plates, struts, straining pieces, horizontal shores/struts, cleats, needles and wedges. Uses needles and cleats to secure against existing walls.
Flying shores are a support system which provides horizontal support to two parallel party walls when removal or collapse of the intermediate building takes place. All types of shoring system of supporting the unsafe structure in which the shores do not reach the ground are the flying shores. If the walls are quite near to each other (distance up to 9 m), single flying shore (fig. 2) in this system operations of the building in the ground are not obstructed. The following points should be kept in mind while connecting the flying shores: the center lines of flying shore and struts and those of the walls should meet at floor levels of the two buildings.
