Description

The present invention relates to a floating floor device suitable for use in an apartment house, an apartment or the like, an apartment house, a gymnasium, and the like. More specifically, the present invention relates to a floating slab through a bundle member on a floor slab. And a floating floor device on which a floor member is placed.

(B) Conventional technology Generally, floor members laid in apartment buildings such as apartments or condominiums, or exercise facilities such as gymnasiums are supported by a number of bundle members arranged on a floor slab such as concrete. Thus, a space is provided between the floor slab and the floor slab to secure a space for piping and wiring, and the heat insulation and soundproofing effects are enhanced.

(C) Problems to be Solved by the Invention By the way, recently, in apartments and condominiums, apartments and condominiums have been developed because carpets and tatami mats laid on discarded veneers may cause mites. In many cases, the floor surface is exposed without using the carpet or the tatami mat, and is used in this state. When a large load acts on the floor, not only will large vibrations be transmitted to the lower room through the bundle members and floor slab, but the floor is too hard, and the comfort during normal walking is impaired. I will. Further, by directly exposing the floor surface, fine vibrations when a shoe sole or a hard object is dropped are also transmitted to the lower room via the bundle member and the floor slab.

Also, in a gymnasium, an aerobics classroom, etc., since various sports, sports, etc. are performed, running around and jumping violently, the load acting on the floor surface is very large, and the shock generated by the floor device during the exercise is very large. If the load cannot be absorbed properly, there is a risk of inconvenience such as spraining of the athlete's feet, and in aerobics classrooms, etc. in a mixed-use building, the impact load during jumping If this is not properly absorbed, the load will be transmitted as noise to the room located below.

Accordingly, an object of the present invention is to provide a floating floor device in which a bundle member is configured to be able to accurately absorb a normal load and a load at the time of impact by different members, thereby solving the above-described problems. It is assumed that.

(D) Means for Solving the Problems The present invention has been made in view of the above circumstances, and for example, as shown in the first, a floor member 1 is supported and laid on a floor slab 5 by a bundle member 6. In the floating floor device configured as described above, the bundle member 6 is wrapped around a glass wool pad 9 with a cushion rubber 10, and a height-adjustable connection between the base member 7 and the floor member 1. Department
13 and exclusively use the cushioning rubber
The glass wool pad 9 absorbs the impact load while absorbing the impact load at 10.

(E) Action Based on the above-described configuration, a relatively small load such as when walking on the floor member 1 is absorbed and attenuated by the cushioning rubber 10 of the base member 7 and gives the floor an appropriate elasticity to walk. Improving the sensation, and the impact load such as when jumping up and landing is absorbed and attenuated by the glass wool pad 9 of the base member 7.

(F) Example Hereinafter, an example according to the present invention will be described with reference to the drawings.

As shown in FIG. 1, the floor member 1 has a structure in which a particle board 3 is sandwiched between plywoods 2, 2, and the floor member 1 has a hole 1a formed by a bundle member 6 arranged on a floor slab 5.
The lower part is supported, and is laid on the floor slab 5 with a predetermined space. Further, the bundle member 6 includes a support portion 7.
And the support portion 7 fits and stores a high-density glass wool pad 9 serving as a buffer member in a cylindrical storage portion 10a formed in a buffer rubber 10.
Of the cushion rubber mounting hardware 11
The cushioning rubber 10 is held by engaging and holding by the engaging portion 11a formed at the same time, and the high-density glass wool pad 9 is configured not to protrude outward from the storage portion 10a. Further, a concave portion 10c is formed at the bottom of the cushion rubber 10, and the concave portion 10c bends when a large load is applied from above and comes into close contact with the floor slab 5, and the load is applied by the glass wool pad 9. Can be directly absorbed and attenuated.

One end of an adjustment bolt 13 is screwed into a nut 12 fixed on the upper part of the buffer rubber mounting hardware 11, and the other end of the adjustment bolt 13 is screwed into a level adjustment nut 15. I agree. Further, the level adjusting nut 15 is fitted and welded to the flat washer 16 and is fixed to the floor member 1 by screwing the flat washer 16 to the back surface of the floor member 1. The portion of the nut 15 projecting upward from the flat washer 16 is fitted into the hole 1a of the floor member 1. Further, a lock nut 17 is screwed to the adjusting bolt 13 as shown in FIGS.
Further, a spring washer 19 and a bolt 13 are fitted between the lock nut 17 and the nut 12 so as to be interposed. A decorative plate is placed and fixed on the upper surface of the floor member 1.

Since the present embodiment has the above-described configuration, the bundle adjusting members 6 in which the level adjusting nuts 15 are fitted into each of the large number of holes 1a and the flat washers 16 are screwed to the back surface thereof. Is laid with a predetermined space opened between the floor member 1 and the floor slab 5.

For example, in an apartment house such as an apartment or a condominium, when walking on the floor member 1, a hard and relatively small load due to shoe soles is absorbed to some extent by the inertia force of the floor member 1. At this time, the load (vibration) transmitted to the support portion 7 via the adjustment bolt 13 without being absorbed is:
It is exclusively absorbed by the cushion rubber 10 and attenuated. In addition, an impact load generated when a person falls or runs around is transmitted from the adjustment bolt 13 to the support portion 17, and first, a part of an initial part is absorbed by bending of the cushion rubber 10, and furthermore, The load that cannot be completely absorbed by the rubber 10 is absorbed by the high-density glass wool pad 9. At this time, the glass wool pad 9 is directly supported on the slab 5 by bending the concave portion 10c formed in the buffer rubber 10, and the glass wool pad 9 does not greatly deform the buffer rubber 10 and a large load is applied. Absorb.

Also, in a gymnasium, an aerobics classroom, or the like, an impact load when a person jumps up and lands is distributed to the floor member 1 and propagated to each bundle member 6. The load transmitted to 7 is
It is softened by the buffer rubber 10 via the buffer rubber mounting hardware 11, and the concave portion 10c is bent and transmitted to the high-density glass wool pad 9 to be absorbed and attenuated. Thereby, even if the intense exercise is performed, problems such as spraining of the foot do not occur. In addition, floating floor devices using the bundle members 6 have recently been used.
It is also effective in body sonic performed as a health method, and vibration caused by heavy bass can be properly absorbed and attenuated by the cushion rubber 10 and the high-density glass wool pad 9 so that it is not transmitted to the outside.

(G) Effects of the Invention As described above, according to the present invention, the bundle member 6 is
Since the glass wool pad 9 is composed of the base member 7 wrapped by the cushioning rubber 10 and the height-adjustable connecting portion 13 for connecting the base member 7 and the floor member 1, a relatively small amount generated when walking is achieved. The load can be absorbed only by the cushioning rubber 10 and the shock load generated when jumping can be reliably absorbed and attenuated by the glass wool pad 9. Can be reliably prevented from propagating to the lower room and surroundings, providing a quiet environment.Also, in the exercise or aerobics etc. performed in the gymnasium, etc. Thus, safety such as injuries to the feet can be eliminated and safety can be ensured. Further, since the glass wool pad 9 made of a relatively brittle material is wrapped with the cushion rubber 10, the pad 9 can be prevented from buckling and collapsing, and the durability of the floating floor device can be improved.

Further, when the base member 7 has a recess 10c at the bottom thereof, when an impact load is applied, the recess 10c bends and the glass wool pad 9 directly absorbs the load. By absorbing an excessively large load, the durability of the cushion rubber 10 can be improved.
