I want to add one horizontal line above and one below the chapter-entry as well.

Before using the scrbook-class, I used this simple solution made by titlesec-package:

newpagestyle{headrules}{

    headrule



    % for twosided layout, use:

    sethead[thepage][chaptertitle][]                 % even pages (left side of book)

    {chaptertitle}{sectiontitle}{thepage}            % odd pages (right side of book)



    % for onesided layout, use:

    % sethead{thechapter. chaptertitle}{}{thepage}  % in this case, the document only has odd pages

}

Working minimum example:

documentclass{book}



usepackage[english]{babel}

usepackage[automark]{scrpage2}

usepackage[pagestyles]{titlesec}

usepackage{blindtext}



titleformat{chapter}[display]{fontfamily{pag}Largebfseries}{titlerule[4pt]chaptertitlename thechapter}{5pt}{large}[{titlerule[2pt]}]

titleformat{section}{fontfamily{pag}normalsizebfseries}{thesection}{5pt}{normalsize}

titleformat{subsection}{fontfamily{pag}normalsizebfseries}{thesubsection}{5pt}{normalsize}

titlespacing*{chapter}{0pt}{30pt}{20pt}

titlespacing*{section}{0pt}{20pt}{10pt}

titlespacing*{subsection}{0pt}{20pt}{5pt}



newpagestyle{headrules}{

    headrule



    % for twosided layout, use:

    sethead[thepage][chaptertitle][]                 % even pages (left side of book)

    {chaptertitle}{sectiontitle}{thepage}            % odd pages (right side of book)



    % for onesided layout, use:

    % sethead{thechapter. chaptertitle}{}{thepage}  % in this case, the document only has odd pages

}



setlength{headheight}{1.1baselineskip}               % adjusting the height of head



pagestyle{headrules}                                   % use this style instead of pagestyle{plain}



begin{document}



blinddocument



end{document}

So, the question now is: How can I solve this without using the titlesec-package anymore? Using titlesec together with a KOMA-class is not recommended, and I prefer to use the scrbook-class instead of book because of those many great advantages (for example addchap and others)...

Do I have to change the pagestyle plain-format for this?

Thank you very much for your help!

The following solution from clemens for separating chapters and addchaps seems to make sense, but it doesn't work in the following minimal-example (don't know why):

documentclass[chapterprefix=true]{scrbook}



renewcommand*chapterheadstartvskip{%

    ifnumbered{chapter}

    {noindentrule{linewidth}{4pt}parvspace*{-4pt}}

    {}%

}

renewcommand*chapterheadendvskip{%

    ifnumbered{chapter}

    {vspace*{-4pt}noindentrule{linewidth}{2pt}parvspace{baselineskip}}

    {}%

}



begin{document}



chapter{Experimental chapter-entry}



addchap{Experimental addchap-entry}



end{document}

It doesn't matter if there's a numbered chapter or an unnumbered addchap - either the selected line is existent or absent in both selectors...

Is there any mistake in my line of thought?

Solution: Upgrading to KOMA-Script v3.18 brought the solution for me, too! Thank you very much clemens and all the others who were helping me!

Thanks a lot for your patient help!

Update

With KOMA-Script Version 3.19 or newer there is another possibility: you can redefine the new command chapterlineswithprefixformat to insert the lines:

newcommandtitlerule[1][1pt]{rule{textwidth}{#1}}

renewcommandchapterlineswithprefixformat[3]{%

  ifstr{#2}{}{}{titlerule[4pt]par}%

  #2#3titlerule[2pt]%

}

MWE:

documentclass[

  chapterprefix=true

]{scrbook}[2015/09/29]% needs version 3.19 or newer



RedeclareSectionCommand[

  beforeskip=0pt,

  afterskip=1baselineskip

]{chapter}



newcommandtitlerule[1][1pt]{rule{textwidth}{#1}}

renewcommandchapterlineswithprefixformat[3]{%

  ifstr{#2}{}{}{titlerule[4pt]parnobreak}%

  #2#3parnobreaktitlerule[2pt]%

}



usepackage{blindtext}

begin{document}

chapter{Experimental chapter-entry}

blindtext

addchap{Experimental addchap-entry}

blindtext

chapter*{Experimental chapter*-entry}

blindtext

addchap*{Experimental addchap*-entry}

blindtext

end{document}

If this should also work with option chapterprefixline=false add the following lines to the preamble:

makeatletter

renewcommandchapterlinesformat[3]{%

  @hangfrom{#2}{#3}parnobreaktitlerule%

}

makeatother

Original answer

If the line above the chapter heading should only be inserted if the chapterprefix is written you could insert this line in chapterformat. This works also for chapter* and addchap*.

documentclass[chapterprefix=true]{scrbook}



RedeclareSectionCommand[

  beforeskip=0pt,

  afterskip=1baselineskip

]{chapter}

usepackage{etoolbox}

newcommandtitlerule[1][1pt]{noindentrule{linewidth}{#1}par}

pretochapterformat{IfUsePrefixLine{vspace{-baselineskip}titlerule[4pt]}{}}

pretochapterheadendvskip{titlerule[2pt]}



usepackage{blindtext}

begin{document}

chapter{Experimental chapter-entry}

blindtext

addchap{Experimental addchap-entry}

blindtext

chapter*{Experimental chapter*-entry}

blindtext

addchap*{Experimental addchap*-entry}

blindtext

end{document}

Despite their name the usual way with KOMA-Script is to redefine chapterheadstartvskip and chapterheadendvskip:

documentclass[chapterprefix=true]{scrbook}



renewcommand*chapterheadstartvskip{noindentrule{linewidth}{4pt}par}

renewcommand*chapterheadendvskip{noindentrule{linewidth}{2pt}parvspace{baselineskip}}



usepackage{blindtext}



begin{document}



blinddocument



end{document}

With slightly altered definitions only number chapters will get the rules. Adding vspace*s at the right place will move the lines closer to the text:

renewcommand*chapterheadstartvskip{%

  ifnumbered{chapter}

    {noindentrule{linewidth}{4pt}parvspace*{-4pt}}

    {}%

}

renewcommand*chapterheadendvskip{%

  ifnumbered{chapter}

    {vspace*{-4pt}noindentrule{linewidth}{2pt}parvspace{baselineskip}}

    {}%

}
