Abstract

PROBLEM TO BE SOLVED: To provide a noise-reducing and heat-insulating panel with an excellent strength, earthquake-proof, airtightness and workability and almost no floor creak or deflection, still with noise reduction. SOLUTION: On the surface of a rectangular lower plywood 1, a joint cleat 3 and reinforcing cleats 4 are fixed to one end and at the other end and at the center in parallel to the longitudinal direction of the lower plywood 1, respectively, and a joint cleat 5 is fixed to one end in the cross direction of the lower plywood 1 to form a frame. A heat insulating material 6 and a soft noise reducing sheet 7 are inserted and adhered into the frame. An upper plywood 2 which has the same size as the lower plywood 1 is somewhat shifted to a diagonal line so as to expose the half widths of the longitudinal and cross joint cleats and fixed thereto to provide lap allowances 8.

る。However, in the heat insulating panel for floors having the above-mentioned structure, since there is only one connecting bar, the strength and the seismic resistance are low, and the floor is apt to generate noise.
Since the joining bar is not incorporated in the short direction, it is difficult to obtain airtightness, the joining part is difficult to be flat, and it is easy to generate distortion.Because the joining bar projects from both upper and lower plywood, In order to combine the next panel, there is a problem that it is necessary to slide from the side and the workability is poor, and in order to add sound insulation, a new sound insulation construction must be performed. The present invention has been made to solve such a problem, and has excellent strength, earthquake resistance, airtightness, workability, hardly any floor noise and distortion, and also has sound insulation. It is an object of the present invention to provide a sound insulation and heat insulation panel for floors, which is also provided.

要である。In the floor sound-insulating and heat-insulating panel having the above-mentioned structure, as shown in FIG. 3, the floor sound-insulating and heat-insulating panel is provided on the upper surface of the foundation or Daihiki A at the building construction site.
First, it is arranged at the upper right corner of the floor surface, the overlap margin 9 of this panel is overlapped with the overlap margin 9 of the upper plywood 2 of another sound insulating and heat insulating panel for a floor, and a screw or a nail B is driven into the overlap part, and It stops at Oiki A. By simply repeating these operations to the lower left corner, the floor surface is covered with sound insulation panels for floors, and a continuous flat floor base is completed. In addition, a joist is unnecessary.

きる。Since the panel is provided with the reinforcing bar 4, it is excellent in strength, and can be firmly fixed to the base or the pulling bar A via the bar, so that it is also excellent in earthquake resistance. And
Due to these synergistic effects, it is possible to almost eliminate floor noise. Further, since the connecting bars are provided not only in the longitudinal direction but also in the short direction, airtightness can be easily obtained, and the joints between the panels are all flat, so that the panels are less likely to be distorted. Also, the amount of overlap on the panel,
By displacing only the upper plywood 2 when providing the overlap allowance, the panels can be combined only by fitting them in from the top, and the workability especially in the leftmost row has been improved. In addition, since the soft sound insulating sheet 7 is incorporated in addition to the heat insulating material 6, it is possible to save the trouble of newly performing the sound insulating work.

If the former is used, it becomes a sound insulation panel for floors with higher strength and is suitable for floors on the second and third floors. If the latter is used, it becomes a sound insulation panel for floors that has higher heat insulation and airtightness, and is suitable for floors on the first floor near the ground. The soft sound insulating sheet 7 may be attached to the heat insulating material 6 in advance. As a result, in addition to the effect of increasing the efficiency of manufacturing floor sound insulation panels, the strength of the heat insulating material 6 is significantly increased.
There is also an effect that the soft sound insulating sheet 7 plays a role of protecting the easily damaged heat insulating material 6. Further, an airtight double-sided tape may be attached in advance to the overlapping margin 8 which is the exposed portion of the joining bar. Thereby, it is possible to save the trouble of performing the airtight construction at the joint between the panels later.
