That is exactly what I was looking for! It resolved all my problems and now I
can use the schema name as a variable in my trigger function, using
'execute' and the string concatenation parameters ('||') which I was not
able to implement before (thanks for the example Glyn!). 
I finally used TG_TABLE_SCHEMA instead of passing the argument with TG_ARGV.
Here the complete solution:

CREATE OR REPLACE FUNCTION trigger_function1()
  RETURNS trigger AS
$$
    begin
        EXECUTE 'select table2.id from ' || quote_ident(TG_TABLE_SCHEMA) ||
'.table2' 
        || ' where value1 ' || ' = ' || quote_literal(new.value1) into
new.id; 
        new.columnx=function1(TG_TABLE_SCHEMA,value1);
     return new;
end:
$$
language plpgsql;
CREATE TRIGGER trigger_function1
  BEFORE INSERT
  ON schema1.table1
  FOR EACH ROW
  EXECUTE PROCEDURE trigger_function1();
