Abstract

The present invention relates to an undercarriage associated with elasticity in an impact-absorbing flooring facility for preventing physical injury to the joints caused by an athlete performing physical exercise or dance on an indoor floor or by accumulating the impact on the floor. More specifically, it is attached to the first joist layer, which is the bottom layer of the joist system of the traditional elastic floor construction method called sprun floor, which assists the sprun floor elasticity and transmits the impact sound generated by the floor and body contact to the lower part. The present invention relates to an auxiliary rubber module system dedicated to a sprue floor, which is composed of one module for minimizing vibration noise and three rubber modules for adjusting the floor level of the floor.

The present invention is a 25mm thick shock absorbing and vibration noise distribution module connected to the bottom of the sprue floor, and 10mm, 5mm thick horizontal level height adjustment module, 3mm bottom horizontal finishing module is easy to control the horizontal level of the floor connected thereto It is composed. The 25mm module, located at the top of the overall module configuration, consists of a circular groove, three air outlets connected to the circular groove, and three protruding structural connections that facilitate the joining of the sprue floor first joist layer. It plays a role in dispersing the vibration noise generated from the body impact in the running motion and transmitted to the first joist layer located at the bottom of the sprue floor.The floor horizontal height adjustment module and the floor horizontal height finishing module are each like a lego block. It is characterized by being constructed to be connected to each other up and down to control the floor level of the final flooring facility up to 3mm error range.

Description

The rubber module system for sprung floor

The present invention is added to the sprunk floor system, which is a traditional shock absorbing elastic flooring facility that prevents injuries due to physical shocks caused by repetitive jump movements in indoor sports and dance activities, to help construct a more effective elastic flooring facility. The main is related to the auxiliary rubber module system for supplementing the sprue floor, and more particularly, the friction occurs between the first joist layer located at the lowermost part of the sprue floor and the concrete bottom surface which is in direct contact with the first joist layer. The present invention relates to a sprue floor auxiliary rubber module system that can mitigate noise and impact and control the horizontal imbalance of the original concrete floor.

In general, athletic and dance flooring facilities have a flooring structure having an elastic structure in order to prevent injuries caused by running or running movements. Among these flooring facilities, there is a sprue floor structure that is widely known in the world.

The sprue floor arranges three to five joist layers at regular intervals (about 40 centimeters) in a grid-like grid to maximize floor elasticity of the flooring substructure. Make it elastic. Sprunk floors are already well known around the world as can be seen in related papers and publications, but there are two problems to be solved depending on the situation of the site to apply the actual sprunk floor to the construction site. First, the sprue floor construction method does not have a complementary device to control the floor level of the actual construction site, so it is not possible to secure the floor level after construction. Although it is not accurate due to the timing problem, there is no need to consider the vibration noise of the lower layer or the connection layer connected to the actual construction site. As a result, how to apply floor minimization and impact noise while maintaining the advantages of the sprue floor is a problem to be solved.

In constructing the sprue floor, it is intended to provide a method of controlling the level of the floor of the site and minimizing the vibration noise generated when using the sprue floor.

The present invention minimizes the noise source by dispersing the vibration noise due to the body contact load and impact applied to the floor in the shock absorbing vibration noise dispersion module of 25mm through the circular air layer and the air discharge layer, and 10mm, 5mm, 3mm each other The three horizontal horizontal modules with different heights can be used in combination to suit the horizontal state of the floor where the sprue floor is to be constructed, so that the floor level can be adjusted to a maximum error range of 3mm.

In the present invention, a plastic or wooden wedge structure which is generally used for height adjustment when constructing a flooring facility such as a sprue floor, and a dustproof rubber used to prevent impact noise are systemized into one block rubber module. In particular, we tried to compose more effective sprunk floors by compensating the problem of horizontal and vibration noise of the remaining sprunk floors. The present invention can be used for all flooring substructures that require elasticity as well as spool floors, and can be used to adjust the flooring level and reduce vibration noise.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

3 is a general form of the sprue floor. As shown, the sprue floor has three joist layers 10, 11, and 12 formed in a mesh lattice shape to create spring-like elasticity with each surface elasticity effect. When jumping from the athletic floor to the floor after jumping or jumping, the vibration and noise are generated on the contact surface of the trunk and the concrete floor with a load and impact of 3-5 times the body weight. In order to reduce the vibration and noise by attaching a shock absorbing and vibration noise dispersion module (Fig. 2) above the three-shaped connection part 3 below the first joist layer 12 of the sprue floor as shown in Fig. Shock Absorption and Vibration Noise As the circular air layer (1) and the air outlet (2) of the module (FIG. 2) closely adhere to the concrete floor, the aerodynamically absorb and disperse shock and vibration transmitted to the first joist layer of the sprue floor. Induce.

And, if the horizontal of the sprue floor construction lower concrete surface 12 is not constant as shown in Figure 4 10mm floor height adjustment module (C), 5mm floor height adjustment module (E), 3mm floor horizontal height finishing module As shown in the application example of FIG. 4, the bottom horizontal height adjustment module protrusion 3 is inserted into the circular air layer 1, or the bottom horizontal height adjustment module (d) is inserted into the floor horizontal height adjustment module ( 5) and protrusions 4 are connected like upper and lower lego blocks to control the level of the concrete surface by each free combination. At this time, the depth of the air layer (1) of the shock absorbing and vibration noise dispersion module is 5mm, and the protrusion 4 of the floor horizontal height adjusting module is 3mm so that the air layer can be maintained 2mm even when connected for the first time height adjustment. It was. 10mm, 5mm, and 3mm floor height adjustment modules can be added freely according to the horizontal situation of the concrete floor surface as shown in FIG. 4, and using a 3mm floor height finishing module, an error range up to 3mm is possible. Horizontal control is possible within.

Claims (1)

In the rubber module that plays a dust-proof role in contact with the concrete floor that meets the first joist layer of the sprue floor, it has a triangular connection, and the contact surface with the first joist layer is evenly and strongly attached. In order to ensure that the dust-proof role is naturally applied every time the floor is impacted from a mechanical point of view, an air layer circular groove and three air outlets connected to the bottom of the rubber module are applied. The circular groove, which is the lower air layer of the rubber module, acts as a dustproof part, and facilitated the connection of the floor horizontal height adjusting module by acting as an insertion part of the LEGO block. The depth of the circular groove was 5mm and the insertion part of the floor horizontal height adjusting module was used. The thickness is 3mm, so that the air layer for dust protection can be maintained 2mm despite the insertion of the horizontal level height for horizontal adjustment, while the horizontal level height adjustment modules of different thicknesses are connected to each other like lego blocks and are horizontally up to 3mm. Configured to be adjustable Vibration noise prevention rubber and horizontal adjustment wedge under the floor system are structured in one rubber module system.
