Description of the Related Art Conventional vibration-isolating floor structures include a method in which the floor slab itself, which is a structural body, has vibration-proofing performance by thickening the floor slab to make it highly rigid, and a buffer layer on the floor slab. A floating floor structure method is known in which a floating floor layer is constructed via a (vibration isolation layer) to reduce the transmission of vibration between the floating floor layer and the building floor slab.

提供することにある。However, in the method of thickening the floor slab and the floating floor structure, there is a problem that the load is increased as compared with the normal floor slab and the cost of the entire skeleton is increased. Further, the floating floor structure method requires a lot of time and labor for the construction, which causes a problem that the construction period is prolonged. The present invention has been devised in view of the above circumstances,
An object of the present invention is to provide a vibration-isolated floor slab that does not involve an increase in load, can be easily constructed, can be manufactured at low cost, and can shorten the construction period.

The anti-vibration floor slab 1 has a rectangular shape in plan view, and its four sides are beams 3
It is surrounded by. Inside the vibration-isolated floor slab 1, there are 5 rebars.
Are arranged, and a plurality of sloshing dampers 7 are embedded and fixed in the vibration antifloor floor slab 1 at the antinode of vibration.

Next, the reinforcing bars 5 are arranged on the form material 9. Next, concrete C is cast on the mold material 9 and cured. At this time, due to the hardening of the concrete C, the sloshing damper 7 is firmly fixed in the concrete C through the fixing hardware 705. Then, after curing, the formwork material 9 is removed to obtain the vibration-isolated floor slab 1.

を構築することが可能となる。According to the vibration-isolated floor slab 1 according to this embodiment,
When the floor slab 1 is excited in the vertical direction, the sloshing damper 7 vibrates integrally with the floor slab 1, and the vibration energy is consumed by the movement of the liquid 703 in the sloshing damper 7 to generate a damping effect. The vertical vibration of is reduced. The anti-vibration floor slab 1 can be obtained by adding the simple process of disposing the sloshing damper 7 before placing the concrete C to the conventional process, and the sloshing damper 7 can be added to the conventional concrete floor slab. Since the structure is embedded, the vibration-proof floor slab 1 that is inexpensive and requires almost the same amount of construction work as the conventional floor slab and does not increase the thickness of the conventional floor slab 1
It is possible to build.
