| 摘要 |
The present invention relates to a horizontal frame structure for supporting adjacent areas (4, 4', 4'') in buildings. The structure comprises joists/beams (1, 1', 1''; 2, 2') in at least one layer that can be grouped into isolated staggeredly supporting subarrays of joists/beams over a certain area. The areas (4, 4', 4'') to be sound-insulated from each other are supported each by only one subarray, respectively, of the staggered subarrays formed by the joists/beams (1, 2; 1', 2'; 1'').
