How To Join Tables With More Than One Attribute Match?

I am trying to turn my raw sql into laravel query builder and I encounter difficulty on how to join multiple tables using with many attributes match.

In this case, I want to join the table jr_h and jr_d with three attributes match (book,p_seq and staff_code) rather than one (book). Raw sql:

 $sql =  "select from_time,to_time,t.staff_code,s.name_t as staff_name,t.book,t.p_code,t.p_seq,p.hrs1,s.img_file, 
        t.hrs_work,p.sharing_cnt  as hrs_work, t.hrs_ot  as hrs_ot from jr_d as t 
        inner join jr_h as p on(t.book=p.book and t.p_seq=p.p_seq and t.staff_code=p.staff_code)  
        inner join astaff as s on(t.staff_code=s.staff_code) ";

Laravel query builder:

   $jr_d = DB::table('jr_d')
        ->join('jr_h', 'jr_d.book', '=', 'jr_h.book')
        ->join('astaff', 'jr_d.staff_code', '=', 'astaff.staff_code')
        ->select('jr_h.*','jr_d.*','astaff.*','astaff.name_t as staff_name')
        ->where('jr_d.ref_group','=','E')
        ->get();

and also want to know if there is a way to make the query faster since it has a lot of data in the tables.

Laravel joins with multiple conditions:

$results = DB::table('jr_d')
            ->select('jr_h.*','jr_d.*','astaff.*','astaff.name_t as staff_name')
            ->join('jr_h', 'jr_d.book', '=', 'jr_h.book')
            ->join('jr_h as p', function($query){
                $query->on('t.book','=', p.book');
                $query->on('t.p_seq','=', 'p.p_seq');
                $query->on('t.staff_code', '=', 'p.staff_code');
            })
            ->where('jr_d.ref_group','=','E')
            ->get();
