What are bearer beams?
Girders are 2,3m deep modular trussed beams that are bolted together end on end to create a stable portal. They are ideal for spanning over a road or river. The Beams can be bolted together end on end to span up to 27m. …
What is a column formwork?
Column Formwork is to be designed to be able to accommodate relatively high fresh concrete pressures as comparatively small cross-sections are concreted quickly. Column formwork is comprised of panel formwork elements or based on individual formwork girders; steel formwork is also available.
What is formwork and its types?
Formwork (shuttering) in concrete construction is used as a mold for a structure in which fresh concrete is poured only to harden subsequently. Types of concrete formwork construction depends on formwork material and type of structural element. The operation of removing the formwork is known as stripping.
What are the characteristics of formwork?
The following requirements should be satisfied by good formwork: Strong enough to withstand dead and live loads. Capable of retaining its shape by being efficiently propped and braced horizontally and vertically. Joints should prevent leakage of cement grout.
What is construction bearer?
Bearers carry the loads from the floor joists across large spans. In upper storeys, if the rooms underneath are large, the joists may not be able to economically span the full width of the room and a bearer will offer an intermediate support. On lower storeys, the bearer may span between the stumps.
What are the qualities of formwork?
Requirements of good formwork
- Easy removal.
- Strength.
- Rigidity.
- Less leakage.
- smooth surface.
- Light weight.
- Quality.
- supports.
What is called formwork?
Formwork is temporary or permanent molds into which concrete or similar materials are poured. In the context of concrete construction, the falsework supports the shuttering molds.
Why formwork is used in construction?
Formwork is associated with concrete structure’s surface finishing – the finer the quality of formwork used, the better will be the surface finishing. Formwork provides excellent structural safety by offering solutions against all overlay loads, producing exceptionally safe and practical structures.
What kind of formwork is used on a beam?
Beam Formwork. Beam formwork has prefabricated formwork sheeting parts (sheeting bottom and side sheeting panels). Such individual parts are manufactured based on the beam dimensions specified in the project. For prefabrication of the formwork sheeting parts, a special preparation table must be manufactured on site.
How big can a beam and bearer be?
The Beams can be bolted together end on end to span up to 27m. Beams and Bearers span between two or more points to create a supporting structure for horizontal formwork.
What do you need to know about formwork?
The formwork is the main means of work in the moulding process of the concrete. Basically the process of formwork making has to meet the following requirements: – The structural component to be produced is to be moulded with the projected dimensions keeping the admissible tolerances.
What are the different types of form work?
In this article named “Types of Formwork”, the different types of formworks are reviewed: foundation, wall, column, beam, ceiling. Foundation formworks can be designed in various ways. Basically there is a difference between formwork for individual foundations, normally designed as socket foundations, and formwork for strip foundations.
