In trestle scaffolding, the work platform is supported on tripods or mobile ladders. This scaffolding is suitable for minimum or repair works. This type of platform supported on the top of Mohole device such as a tripod, radar. This type of scaffold is used for repairs, notes, paintings, etc.Īlso, read: What Is Contour Interval | Calculation of Contour Intervals | Uses of Contour Intervals in Surveying 5. In suspended scaffolding, the work platform is suspended from the roofs with the help of cables or chains, etc., it can be raised or lowered to the required level. This type of scaffolding is suitable for hight steel frame construction as well as for mailer works such as painting distend peering etc.
TRESTLE SCAFFOLDING DEFINITION FREE
When the floor near the wall is free of traffic,.When the terrain is unable to support standards,.Generally, cantilever scaffolding is used in conditions such as Care must be taken when building scaffolding on a cantilever. In the other type, the needles are supported inside the floor through the openings, and this is called independent or double frame scaffolding. This is called a single frame type scaffolding.
TRESTLE SCAFFOLDING DEFINITION SERIES
It is a type of scaffolding in which the patterns are supported on a series of needles, and these needles are removed through holes in the wall. Inclined supports called reacting source, are provided to prevent the slipping of scaffold away from the wall.Īlso, read: WPC Board | Features of WPC Board | Disadvantages of the WPC board | Usw of WPC 3. This type of scaffolding is stronger than the single scaffolding and is used in the construction of stonework some times in addition to the diagonal braless. Where the verticals posts cannot be placed on base plates or in holes made in the ground, it should be suitably placed and braced for lateral stability.Ī popular method in such cases is to place the vertical post in a steel barrel of 60 cm in height and of suitable diameter filled with compacted earth as shown above fig.Īlso, read: What Is Bar Bending Schedule | Preparation as Per Bs 4466 | Tolerances as Per Bs 4466 2. Hence it should rest on a cross piece (called bridle tube) tied at the wall end of the adjacent putlogs.Ĭross bracing in the vertical planes between the verticals are also to be introduced for lateral stability. If the putlog level coincides with an opening in the wall, it cannot be placed on the wall. The cross members (putlogs) are tied to the standards at the outer end and rest on the walls being built inside. This type of scaffolding moot of members except platforms is usually made of bamboos and standards which are driven into the ground at a distance 1.5m to 2.0 m apart and about 1.2 m away from the wall to be constructed. This type of scaffolding is mostly used for brickwork and consists of an outer row of verticals (called standards) to which longitudinal members are tied at different levels of working (see above fig.). In addition, it also provides some degree of support for a standing structure during the construction phase. This is done to ensure the safety of workers while the building is being maintained or constructed. Therefore, whatever the size of a building, scaffolding will always be necessary. It is installed before construction or maintenance work begins. Scaffolding is a temporary platform used to lift, support, and supply materials during a construction process for the repair or cleaning of a structure.
