Description

The flooring system of a gymnasium and the bolt adjusting level cushion}

The present invention relates to a floor structure for indoor stadiums and a level cushion adjusting bolt used therein, having a moisture proof sheet and a waterproofing plywood layer, having a moistureproof, dustproof and soundproof function, and minimizing structural deformation, The height adjustment is possible at the same time as the shock absorption, and to provide a stable and economical level cushion adjustment bolt.

In general, the typical structure of indoor floors is to install pedestals on concrete floors, and to fix the yoke, feldspar and parquet floors sequentially, and to absorb the impact of the load on the floorboards. An elastic rubber pad may be inserted below.

However, due to the nature of the stadium, such a floor structure is left for a long time without adjustment of temperature and humidity during the off-season, and at this time, deformation or corrosion of materials used, such as yoke and long-sleeved wood, easily occurs, resulting in durability. There is a problem of deterioration.

In the case of the conventional indoor stadium, the floor area is large, and it is difficult to precisely horizontally install the floor surface during the floor construction, so that a height deviation of about 100 mm is largely generated on the floor surface normally constructed.

Conventionally, the height adjustment device which has been commonly used by easily adjusting the level and imparting a shock absorbing function in the floor construction is shown in FIG. 1, which is mainly made of plastic and has small serrated fine uneven portions 5 on the hypotenuse. Is formed of a triangular shape formed of a lower block (1) and the upper block (2).

That is, the lower block 1 having the fine concavo-convex portion 5 on the hypotenuse of the right triangle, and the upper block 2 having the fine concave-convex portion 5 engaging the hypotenuse of the lower block 1 on the hypotenuse. And, the upper surface of the upper block (2) has a rubber pad layer (3) formed with a rectangular wood gripping portion 4 is assembled as shown in Figure 1 has an integrated configuration.

The height adjustment device can adjust the level of the floor by pushing the upper block 2 up and down on the comb side of the lower block 1 along the interdigital fine concave-convex portion 5, the rubber pad layer (3) It has a shock absorbing function.

However, when the fine recesses 5 of the upper and lower blocks 1 and 2 are weakly bited due to the separation between the height adjusting device and the yoke, the sliding of each other is caused by the momentary impact load on the floor. The phenomenon occurs, and even separated from each other, the problem that the function as a height adjustment device is implicated, it is a problem in the stability of the floor, a lot of fine unevenness (5) in the manufacturing process of each block (1, 2) Because of this formation, the manufacturing process is difficult, which causes a decrease in workability and a unit cost increase.

In addition, the bottom of the lower block (1) is configured to directly contact the bottom surface is separated between the height adjustment device and the yoke, or because the impact force applied on the floor floor is transmitted directly to the floor floor will cause severe noise in the lower floor. .

In addition, the height of the upper block (2) along the oblique surface of the lower block (1) as much as possible to adjust the height is only about 25mm, if the deviation of the floor itself is very large, another support on the floor Inevitably caused to have more.

The present invention has a moisture-proof sheet installed on the floor layer, by providing a plywood layer on the Jangsun wood, has a moisture-proof, dust-proof and soundproof function, thereby minimizing the deformation of the floor structure for changes in temperature and humidity, etc. It is an object to provide a floor structure for the stadium.

In addition, the present invention consists of a cushion rubber plate made of rubber with a hardness of 60 to 65, and a body portion made of reinforced plastic, and has a shock absorbing function to effectively block the transmission of vibration and shock, and at the same time by adjusting the female and male threads. By allowing height adjustment, it is aimed to provide a stable and economical level cushion adjustment bolt at the same time as greatly improving the height adjustment width compared to the conventional height adjustment device that only fine adjustment of the height.
