Placing vertical lines between columns

Question

I have a document that looks like this

The horizontal line is just a \hrule, but the two vertical lines are made with a textblock. Is there an easier way to place them?

Using a table environment is not an option, since the vertical space between items goes bananas.

\documentclass{article}
\usepackage{multicol,tabularx}
\usepackage[top=0.5in,bottom=0.8in,left=0.8in,right=0.8in,landscape]{geometry}

\usepackage[absolute]{textpos}
\setlength{\TPHorizModule}{1cm}
\setlength{\TPVertModule}{\TPHorizModule}
\textblockorigin{10mm}{10mm}

\begin{document}
\begin{textblock}{3}(6.3,0.75)%%%Places a vertical line
\rule{0.1mm}{18cm}
\end{textblock}

\begin{textblock}{3}(15,0.75)%%%Places a vertical line
\rule{0.1mm}{18cm}
\end{textblock}

\begin{tabularx}{\textwidth}{X}
\centering{FUS} 
\end{tabularx}
\hrule

\begin{multicols}{2}
\begin{minipage}{0.44\textwidth}
\vspace{15cm}   
RO
\end{minipage}

\begin{minipage}{0.44\textwidth}
DAH
\end{minipage}
\end{multicols}
\end{document}

Answer 1

This gives a similar output. Is it 'easier'?

The height of the vertical rules is calculated automatically using \pagegoal (total vertical space available within margins) and \pagetotal (amount of vertical space already used on current page).

\documentclass{article}

\usepackage{calc}
\usepackage[top=1.3cm,bottom=2cm,left=2cm,right=2cm,landscape]{geometry}

\begin{document}

\centering
FUS
\hrule{}

\newlength\minipageheight
\setlength\minipageheight{\pagegoal-\pagetotal-1mm}

\begin{minipage}[t][\minipageheight][t]{0.33\textwidth}
\vfill
RO
\end{minipage}%
\vrule{}
\begin{minipage}[t][\minipageheight][t]{0.33\textwidth}
\smallskip
\centering
DAH
\end{minipage}%
\vrule{}
\begin{minipage}[t][\minipageheight][t]{0.33\textwidth}
\smallskip
\centering
JOOR
\end{minipage}

\end{document}
