Abstract

The present invention relates to a floor panel fixture and, more specifically, to a floor panel fixture capable of reducing transfer of vibration or impact to a floor by effectively buffering and blocking vibration or impact. According to the present invention, the floor panel fixture effectively buffers vibration or impact transferred to a support rod through a floor panel and an upper base through a spring member, thereby reducing vibration or impact from being transferred to a floor. By integrally forming or fixing a grip clip part capable of gripping the floor panel on the upper base on which the floor panel is mounted, it is possible to stably install the floor panel. In addition, the height of the floor panel fixture according to the present invention can be adjusted by rotating the upper base on which the floor panel is seated with respect to a lower base, and thus the height of the floor panel can be uniformly formed. Also, the floor panel can be installed at a height desired by a user. It is possible to easily adjust the direction of the grip clip part even without rotating the upper base according to the direction of the floor panel by rotating the grip clip part with respect to the upper base.

Description

Fixing device for floor panel

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a floor panel fixture, and more particularly, to a floor panel fixture capable of effectively reducing the transmission of vibrations or shocks to the floor by effectively buffering and blocking vibrations or shocks.

Generally, the interlayer noise of a building is transmitted to various places such as a multi-storey house and a commercial building through a structure such as a floor slab, a pillar, and a wall.

Insulation of sound for interrupting this interlayer noise refers to interception of sound interception from the outside. It is made of a partition or fleshy wall made of material that does not vibrate or transmit vibration. It is better to make windows and the like double, and it is more effective to use a sound-absorbing layer such as a thick cloth curtain or felt.

The above-mentioned sound insulation is an important factor for blocking noise between important layers in a building divided into a plurality of compartments and layers, while the interest of residents to a comfortable living environment level is increased, while the thickness of materials used in buildings is gradually increasing As thinner and lighter, the sound insulation performance of the building members is lowered, and now the sound insulation performance of the members becomes the most important factor determining the residential performance level.

Particularly, it can be said that apartment houses which share the floor and walls are more likely. This tendency will further intensify as the rationalization of the rescue plan and the attempt to reduce the cost due to the high-density and high density of apartment buildings continue.

In a multi-storey multi-storey building such as an apartment or a villa, a technique to prevent noise from being transmitted to the lower or upper floor due to shock or noise generated in the floor, Is being generalized.

As described above, the bottom structure of a joint building is designed to reduce shock energy when it is necessary to reduce the noise through the sound insulation structure and materials for heavy and light impact sound. To minimize the energy transmitted to the structure, I am using it.

Typical floor-to-floor noise suppression material is installed between the floor slab and foamed concrete to isolate the Ondol floor from the wall to reduce the impact energy transmitted to the structure, or to install an air layer and a sound absorption layer between them to disperse and absorb noise .

Floating floor structure is one of the most effective methods to reduce floor impact sound. Generally, there is a structure to install cushioning material between floor slabs and Ondol construction layers, and there are two methods of wet and dry.

However, the conventional noise preventive material is installed in the lower part of the flooring, and when the continuous vibration and shock are transmitted, the performance is reduced and the lifespan is shortened. When large vibration or noise is generated, sound absorption or buffering can not be performed properly.
