Description

[Detailed description of the invention] The present invention relates to improving the sound insulation properties of floor panels for upper floors.More specifically, the present invention relates to improving the sound insulation properties of floor panels for floors. At the same time as constructing the vertical frame 2 of
Notches 12 are provided at regular intervals on the lower edge of the temporary fixing plate 11, step portions are recessed on both lower surfaces, and insertion protrusions 6 are formed at both ends of the square rod-shaped ceiling base material 5. A cushioning material 7 is wrapped around the inserting protrusion 6 and the cushioning material 7 are fitted into the notch, and a long metal horizontal frame 10 having a U-shaped cross section is fitted to the end of the vertical frame 2. This relates to a floor panel for an upper floor, in which a floor surface material 9 is attached to the upper surface of a vertical frame 2, and a ceiling board 8 is attached to the lower surface of a ceiling base material 5.

In the conventional example, as shown in FIGS. 1 and 2, a floor surface material 9' is attached to the upper surface of the upper floor panel frame 4', and a ceiling board 8' is attached directly to the lower surface. Ta.

In this case, there is nothing between the floor surface material 9' and the ceiling board 8' to absorb vibrations, so the floor surface material 9'
The vibration generated in the ceiling board 8' is directly transmitted to the ceiling board 8', resulting in poor sound insulation.

The present invention was made in view of the drawbacks of the conventional example,
The purpose of this invention is to insert the insertion protrusion of the ceiling base material together with the cushioning material into the recessed hole of the upper floor panel frame, and to insert the ceiling base material that can protrude downward from the bottom surface of the upper floor panel frame. By attaching the ceiling board to the bottom surface of the wood and preventing the ceiling board from coming into direct contact with the floor panel frame for the upper floor, we prevent the vibrations generated in the floor surface material from being transmitted to the ceiling board and improve sound insulation. To provide floor panels for upper floors that can be improved.

The present invention will be described in detail below according to illustrated embodiments.

The horizontal frame 1 is composed of an iron horizontal frame 10 having a U-shaped cross section and a temporary fixing plate 11.

The temporary fixing plates 11 are long plates arranged facing each other,
The vertical frames 2 are arranged at regular intervals between the temporary fixing plates 11, and the vertical frames 2
The end of the plate is nailed to the temporary fixing plate 11.

Further, at the lower edge of the temporary fixing plate 11, a notch 12 with a downward opening is provided in the middle of the vertical frame 2.

When this temporary fixing plate 11 is inserted into the opening groove 13 of the horizontal frame 10, the notch 12 and the lower piece 14 of the horizontal frame 10 form a recessed hole 3 that opens inward.

The ceiling base material 5 is square rod-shaped, and both ends of the lower surface are recessed in a step-like manner, and insertion protrusions 6 are formed at both ends of the ceiling base material 5.

A cushioning material 7 made of an elastic material such as rubber or styrene foam is wound around the outer periphery of the insertion projection 6, and the insertion projection 6 is fitted together with the cushioning material 7 into the notch 12 from below. A ceiling base material 5 is constructed between both temporary fixing plates 11.

After temporary assembly in this manner, the horizontal frame 10 is fitted into the temporary fixing plate 11 from the outside, and the horizontal frame 10 is fixed to the vertical frame 2.

In this case, since the opening groove 13 of the horizontal frame 10 and the width of the temporary fixing plate 11 are approximately the same, the lower surface of the ceiling base material 5 will protrude downward from the lower surface of the horizontal frame 10.

After forming the floor panel frame 4 for the upper floor in this way, a ceiling board 8 is attached to the lower surface of the ceiling base material 5 protruding from the lower surface of the horizontal frame 10, and then the horizontal frame 10 and the vertical frame 2 are attached.
A floor surface material 9 is attached to the upper surface of the floor panel A to form an upper floor frame panel A.

The upper floor frame panel A thus formed is constructed on the floor of the second floor or higher at the site, and a ceiling decorative board is attached to the lower surface of the ceiling board 8.

The insertion protrusion 6 with the cushion material 7 wound thereon is inserted into the recessed hole 3 of the horizontal frame 1 consisting of the notch 12 and the lower piece 14, and the ceiling base material 5 is constructed between the horizontal frames 1. Therefore, when children play or move furniture, noise is generated and vibration is generated in the floor surface material 9, but this vibration of the floor surface material 9 is absorbed by the cushion material 7, and the ceiling base material 5, and since the ceiling board 8 is attached to the lower surface of the ceiling base material 5 which protrudes downward from the lower surface of the horizontal frame 1,
A gap is created between the ceiling board 8 and the horizontal frame 1, so that the ceiling board 8 does not come into contact with the horizontal frame 1, and vibrations generated in the floor surface material 9 are not transmitted to the ceiling board 8. This has the advantage that the sound insulation properties of the upper floor panel A can be improved.
