The present invention relates to a support of a double flooring material and a method of manufacturing the same, and a method of using the support, and in particular, a support of a double flooring material and a method of manufacturing the same and a method of using the support to reduce the floor impact sound, increase the feeling of walking and easy installation thereof. It is about.

In general, in the office space such as the computer room, double flooring is basically applied to process the wire piping treatment to the bottom of the floor, but the general office double floor support is made of steel only, so there is no cushioning and floor impact sound reduction performance. It is difficult to apply for housing.

Specifically, the problem of floor impact sound that occurs when a hard support is applied, that is, the light impact sound, which is a light sound such as the sound of dragging the chair and the footsteps, as well as the light impact sound, such as the sound of the footsteps, as well as the heavy sound of people thumping Phosphorus 'weight shock sound' is transmitted to the lower floor as it is, causing discomfort to people downstairs.

You will also easily feel tired when you walk on the hard, raised floor. Since these matters are a very sensitive part of housing, there are many complaints.

In addition, soft rubber is used to maximize the floor shock effect, which may cause problems such as tilting or sitting down when lifting heavy furniture such as a refrigerator, bookshelf, and piano due to excessive cushioning properties. Therefore, it creates anxiety for those who are familiar with the domestic culture of hard ondol floor lifestyle.

Figure 1 shows a conventional double-floor support for the office, the support includes a steel plate-shaped pedestal (4), including a height adjustment bolt receiving portion 6, a height adjustment bolt and bolt loosening lock (5) It consists of the head 1 '.

In the case of such office double flooring, a support made of steel is applied to the bottom of the upper panel, and a large adhesive area between the floor and the support and the rigid characteristics of the steel facilitates the transmission of shock sounds, and thus is disadvantageous in reducing impact sound.

In addition, in the long term, the horizontal level of the double flooring is changed by the gradual loosening of the height adjusting bolts due to people's walking, which eventually leads to the occurrence of a flaw in the double floor. In order to prevent this phenomenon, a separate accessory must be additionally applied. When using the double bottom support, the impact on the floor impact sound and the rigidity of the height adjustment bolt can be said to be very important.

The main reason that the support is disadvantageous in reducing the floor impact sound is to be designed to withstand relatively heavy loads, so the adhesion area with the floor is designed to provide stability of the support, which is easy to transmit the impact sound along with the rigid characteristics of the steel. This is because it is disadvantageous to reduce the floor impact sound.

In addition, since it is made of steel only, there is no cushion, and the pedestrian feels less tired, which makes it easier for pedestrians to feel tired. As such, the steel material does not have a floor impact sound reduction performance effect or is a factor of inhibition due to the 'Sound Bridge' effect of transferring the impact sound to the floor. Therefore, if the office double floor support is applied to apartments such as Korean apartments as it is, it may cause floor noise problems.

A secondary dustproof means configured to block the transmission of vibration and noise therebetween is provided, and the auxiliary dustproof means is not only pressed into the insertion groove and the insertion groove formed to a certain diameter in the upper center of the housing, but also coupled to insert the fixing bolt in the center. A ball is formed and is composed of an auxiliary dustproof pad for dustproofing between the housing and the fixing bolt, the auxiliary dustproof pad is configured to improve the dustproof effect by forming a space between the coupling hole and the outer peripheral surface.

In addition, a spherical coupling groove and a coupling protrusion having a predetermined curvature are formed at the end of the fixing bolt and the center of the insertion groove so that the contact portion of the fixing bolt and the housing may be inclined at a predetermined angle. If so, the position limitation is made, and a configuration in which the fixing bolt can be tilted by a predetermined angle is proposed.
