Difference between King Post Truss & Queen Post Truss
Concept about King Post Truss
In the case of the roof structure and bridge frameworks, the king post truss has been used. The king post truss is simple in design, having higher strength and also being economically efficient. The king post truss has been made with steel or timber, two principal rafters and a vertical central post, which helps to create the triangular structure.
Discuss the key components of the King Post Truss
Rafters
The rafters are the sloping members of the king post truss, which help to form the sides of the triangle. The rafter helps to resist the load of the roof and transmit the loads to the verical king post.
King posts
The king post helps to strengthen the roof truss and also helps to transfer the roof load to the foundation structure.
Tie beam
The tie beam of the king post truss helps to resist the outward thrust from the rafters. Thus, the tie beam helps to prevent the roof from spreading outwards.
Struts
In some cases of the king post truss, diagonal struts have been added. These components help to support the rafters, as well as enhance the load-bearing capacity.
Discuss the applications of the King Post Truss in the construction project
Construction of bridges
In the case of timber bridges or steel bridges, the king post truss has been applied.
Construction of pavilions and public structures
In case of the open-air structures, including park shelters, pavilions or gazebos, the king post truss has been used. This king post truss helps to provide an aesthetic visibility of the public structures.
Used in industrial sectors
The king post truss has also been used in the large-span industrial buildings because of its higher load-bearing capacity.
