Description

[Detailed description of the invention] (Industrial field of application) This invention, when constructing a floor structure by laying floor panels, arranges a pair of support joists on the back side of the top material of the floor panel, and This invention relates to a vibration-isolating structure of a floor panel that partially forms a highly rigid joist area by connecting the floor panels.

(Conventional examples and problems) Normally, the vibration-proof structure of a floor is made by increasing the effective cross section of the floor components to increase the rigidity of the floor itself, or by filling the floor panel with vibration-proofing material to absorb vibrations. I often do this.

However, when constructing a floor by laying panels, it is not only uneconomical to increase the effective cross-sectional area of the frame material and top material, which are the structural members of the floor panel, but also As shown in the figure, each component is arranged in a balanced manner from all directions, such as the front, plane, and side, so vibrations generated on a part of the top surface of the floor panel will also cause the entire floor panel to become one. Causes vibration as a diaphragm.

In this balanced state of lying on the floor, the damping effect of the entire floor was significantly reduced.

(Purpose of the invention) Therefore, in order to solve the above problems, the present invention constructs a partial rigid area with a pair of joists and a connecting plate on the back side of the top material constituting the floor panel, so that the entire floor panel becomes The present invention provides a vibration isolation structure for a floor panel that improves the vibration isolation performance of the floor by increasing the damping properties of the entire floor panel due to its non-uniform formation.

(Summary of the invention) In order to achieve the above object, the vibration isolation structure of the floor panel of the invention is characterized by having a pair of support joists arranged on the back side of the top material, and connecting the support joists with a connecting plate. shall be.

(Embodiments of the invention) Hereinafter, embodiments of the invention will be described based on the drawings.

Note that the same parts as those in FIG. 3 are given the same reference numerals.

FIG. 1 is a sectional view of a floor panel having a vibration-proof structure according to the present invention.

The floor panel 1 has a so-called single-sided panel configuration in which a top material 10 such as plywood is attached to the upper ends of frame members 11, 11 with adhesive, nails, or the like.

Approximately in the center of this floor panel 1, support joists 12, 12 made of elongated material approximately equal to the frame material 11 are fixed to the back surface 10a of the panel material 11 with adhesive or nails at a predetermined interval. has been done.

Moreover, the bottom surfaces 12a, 12 of the support joists 12, 12
A connecting member 13 is spanned between a. The connecting member 13 is provided with fitting grooves 13a, 13a, into which the bottom surfaces 12a, 12a of the support joists 12, 12 are fitted and fixed.

Note that the connecting member 13 does not have to be formed so as to cover the entire lower surface of the support joists 12, 12, and may be connected in a flying board shape using a plurality of band-like connecting members 13. Further, specific means of connection include fixing with nails, adhesive, etc.

Next, the vibration-proofing effect of the floor panel having the above structure will be explained. For example, if the impact load exceeds the setting,
, vibration energy with a large amplitude is generated in the face material 10. However, since a rigid area is partially formed on the lower surface of the floor panel 1, the supporting joists 1
2 and 12, the energy is not uniformly propagated to the floor panel but is dispersed, and the floor as a whole becomes gradually attenuated.

In this way, the vibration isolation structure of the floor panel is constructed by partially providing a so-called rigid region within the floor panel, increasing the rigidity of a portion of the floor panel 1, thereby exhibiting non-uniformity with respect to vibration, and eliminating this non-uniformity. The uniformity disperses vibration energy and improves the vibration damping performance of the entire floor. In other words, the part surrounded by the support joist and the connecting member can be seen as a large joist formed by the cross section thereof, and forms a rigid region different from the rigidity of the surrounding frame material. This results in the formation of non-uniform portions when the floor panel as a whole is viewed in terms of material.

It should be noted that the above-mentioned vibration damping effect can be achieved even higher by setting the size of the support joists 12, 12, the spacing, the shape, thickness, etc. of the connecting member 13 according to the frequency of vibration occurring in the face material 10. In particular, it is preferable to use a material with higher rigidity than the face material for the connecting material, as this will further increase the non-uniformity.

FIG. 2 is a partially omitted sectional view showing a floor structure constructed by laying floor panels 1, 2, . . . .

As shown in the figure, even when a floor structure is constructed by laying floor panels 1, 2, . . . , each of the floor panels 1, 2, .

Therefore, vibrations are not propagated to the entire floor, and effective vibration isolation performance can be obtained for the entire floor.

(Effects of the invention) As described above, a vibration-proofing structure can be easily formed on a floor panel, and excellent vibration-proofing performance can be exhibited over the entire floor.

Further, since there is a space between the support joists and the frame material, this space can be used to facilitate the interconnection work of floor panels, and the space formed by the support joists and the connecting material can be used as an effective space for piping and wiring.
