What is the bottom board?
When framing the building, the structural integrity of the building is the base of the lower plate, as well as the pins, the upper plate, the window sill and the ceiling or the roof beams. Also known as the only board, the lower plates can be considered as an extension of the foundation on which the roof, ceilings and walls are. In the wooden frame building, the lower plates would most likely be wood, although various other materials such as steel, concrete or composite materials can be used. On the inner wall project, the vertical pins are mounted and then nailed or screwed on the site with a underflow and the lower plate, or if it resulted in damage to the floor, simply boarded the bottom plate. The Čavo is then nailed or screwed into the top plate, which is at the ceiling level. The bottom plate is the foot of the walls, the studs are the ribs of the top plate is the head of the wall.
usually, interior framing in the completed structure must be made verticalE; The bottom plate nailed to the substrate, nailed nailed or screwed to the bottom plate and then to the top plate. The construction of the outer wall is usually carried out horizontally. The bottom plate, top plate and pins are nailed or screwed horizontally on the substrate and the whole structure was then raised as one complete assembly, to the correct position on the substrate. Roofs and ceilings are not generally built and therefore allow an uninhibited wall erection.
in the construction of wood, lower plates, pins and upper boards are commonly Douglass Fir, Pine or Hemlock. The wood is easily accessible, relatively cheap and robust enough to ensure a reasonable durability of the structure. Wooden beams, generally larger than two to four or two-by-one boards, which are usually used in the construction of wooden buildings, can be used as top or lower plates for additional load strength.
Quite often, newcomers in construction confuse the bottom and top plate with footers and heads. In the installation or design of the window or door openingThe header and footer is the term for the lower part of the building foundation. Although similar in the concept, the terms are differentiated in order to clarify. One would not want to build a frame of a window or door, or pour the foundation when what is actually required, the wall frame is.
