Description

Floor structure for sports facility

The present invention relates to a sports flooring system (Sports flooring System). More specifically, the present invention relates to a structure and a method for constructing a wooden floor in a school gymnasium, a social sports facility as a social welfare facility, an international standard gymnasium for indoor sports, and the like.

The floor system for sports facilities was introduced in Korea since the 1986 Asian Games and the 1988 Olympic Games were established. Mainly, the floor system for the sports facilities was installed according to the drawing designed in the US, but it was introduced without considering the reality of Korea. As a result, it became an obstacle to the expansion and expansion of sports facilities. In order to reduce the initial investment costs, the floor system for sports facilities in northern Europe began to spread at a low price in Korea by lightening the structure, but the initial investment cost was reduced compared to the US system because the choice of flooring material did not consider Korea's climate environment and maintenance. However, due to the problems that appear after installation, it is expensive to repair and maintain.

The floors for sports facilities must meet the German Industrial Standard DIN 18032-2 as the global quality standard to be checked for quality. The German Industrial Standards regulations require that sports floors meet the criteria for shock absorption, shock resilience, deformation control, ball rebound, and behavior under moving loads. It is designed to meet the six requirements of behaviour under rolling load and sliding behaviour.

A typical installation structure of a floor for a physical education facility is to install a pedestal on the floor (mainly concrete floor), yoke on it, install the joist on the yoke, and then fix the parquet on the joist. An elastic rubber pad is placed under the yoke to absorb the impact of the load on the floor. Conventionally, pedestals, yokes, and joists for constructing athletic floors are mainly used for pine trees.

If Yosong is used as a yoke and joist, it will not cause problems if the indoor environment (humidity, temperature, etc.) is strictly controlled, but the indoor environment will change because the air conditioning system is not operated when the gym is not used. At this time, when the temperature and humidity changes, the pine nuts are not treated with materials such as surface treatment separately, so that the moisture content changes, and deformation and corrosion easily occur.

Deformation or erosion of yoke and joists, which are the substructures of the floor, will soon affect the performance of the floor. Therefore, the floor of athletic facilities cannot meet the original quality standards, and the durability is degraded.

The inventors have developed a floor structure for solving the above problems in the floor structure for the conventional sports facilities. In other words, the use of yoke or joists, or new materials with less strain on yokes and joists, has developed a floor structure for sports facilities that can also protect the environment by reusing recycled materials to be disposed of as waste.

It is an object of the present invention to provide a floor structure for a sports facility with little deformation of the structure as the indoor environment of the sports facility is changed and durable.

It is another object of the present invention to provide a flooring structure for an athletic facility that can contribute to environmental protection by recycling the materials to be disposed of as waste remaining in the production of other products.

According to the embodiments shown in the accompanying drawings will be described in detail the present invention.

Conventionally, floors for sports facilities have mainly used non-transfer materials for forming the substructure of the floor, such as pedestals, yokes, and joists. Misong has high absorption rate, weak compressive strength and flexural strength, and has weakness that is easily deformed and decayed when absorbed. However, because the price of wood is relatively cheap, it is widely used for the floor structure of flooring.

If the indoor environment is controlled by an air conditioner for 24 hours, even if the wood having a non-transmission or similar performance can be maintained a certain durability, but the room used for gym purposes is not always used space because it is difficult to always air conditioning. Therefore, if the substructure made of unconveyed is constructed in the gym, where it is difficult to maintain air conditioning at all times, frequent defect repair work is inevitable due to defects.

The present invention is a floor structure that can minimize the deformation of the gym floor structure even in an environment where the change in temperature and humidity is severe, and the environment is difficult to constantly operate.

In the present invention, the material used as the substructure of the gym floor is a combination plywood, which is a special laminated wood. Combination plywood is an aggregate plywood produced by appropriately selecting the type of adhesive when the plywood is manufactured, the thickness is usually made of 28mm. Combination plywood is used as a pallet when manufacturing containers because of its excellent flexural strength and poor deformation.

Table 1 shows the results of comparing the flexural strengths of the combination plywood and the unsong. As shown in <Table 1>, flexural strength is more than 40% better than Misong.

Combination plywood is mainly used for containers, and scraps cut for containers are disposed of. By adopting the discarded combination plywood to the lower part of the gym floor, the inventor can use the excellent physical properties of the combination plywood, and recycle the discarded sack to contribute to the preservation of the environment.

In addition, the inventors have developed a vibration-proof rubber that can absorb vibration and shock on the floor of the gym, so that it can effectively block the transmission of vibration and shock.

The gym floor structure of the present invention will be described according to FIG. 1 to FIG.

Gym floor structure of the present invention is installed across the pedestal 11, the pedestal 11 is installed on the concrete floor (1), joist 13, the yoke (13) attached to the dust-proof rubber 12, joist 13 14 and the floor board 15 fixedly installed across the joist 14. Between the pedestal 11 and the yoke 13, that is, below the anti-vibration rubber 12, a horizontal adjustment plate 17 can be put in order to level.

The pedestal 11 uses a combination plywood bag in a square. The pedestal 11 does not have a special specification, and may be a material resistant to corrosion because it is in contact with the bottom of the gym. Combination plywood pieces meet these requirements.

The yoke 13 across the pedestal 11 is also made of a combination plywood. The yoke receives the load of the joist 14 and serves to transfer it to the pedestal. Therefore, if the yoke is deformed or corroded, the floor will lose its function, so a durable material is required. Combination plywood meets these requirements. The yoke has a thickness of 28mm, which is the manufacturing thickness of the combination plywood, and the width is adjusted according to the loading load according to the main use of the gym.

On the yoke 13, a joist 14 is installed. The joist serves to transfer the weight and load of the floor board 15 to the yoke 13. Therefore, the strength characteristics of the material used as joists play an important role in maintaining floor performance. The joist spacing depends on the strength of the floor and the strength of the joist itself. If the strength of the joist itself is excellent, it can lead to the reduction of material and installation labor cost by widening the joist layout interval.

In the floor structure of the present invention, a combination plywood rod having excellent strength characteristics is used. Combination plywood is a very economical tool because it takes advantage of the scrap that needs to be disposed of after container construction.

The yoke 13 used in the present invention develops and uses a yoke for the floor of an athletic facility in which a dustproof rubber 12 is installed at a predetermined interval in a combination plywood mat. Since it is difficult to install the anti-vibration rubber in the field, the anti-vibration rubber is fixed in advance in the factory at a predetermined interval (prefabricated). On the site, the anti-vibration rubber is placed on the pedestal 11 installed at a predetermined interval. 14) The installation is complete by combining across.

In the general floor structure for physical education facilities, one or two plywoods are laid on the joist, and floorboards are often installed on them. This is to distribute the load on the floorboards to the joist, but in addition to the installation cost and labor costs, if there is moisture between the floorboards and the floorboards, the floorboards are corroded and the risk of bacteria outbreaks. There is a problem that the durability of the fall.

In the present invention, it is possible to save the material cost and installation cost when laying the plywood using the athletic flooring joist excellent in strength characteristics, the lower part of the floorboard can be ventilated, so that the flooring of the athletic facility can always be kept healthy. .

The yoke 13 and the joist 14 used in the present invention mainly use the remaining combination plywood edges, and thus often cannot be obtained as long as desired. Thus, as a combination plywood snip, it is necessary to make long joints such as yokes and joists. 5 shows the joint method. In other words, the stalk combination plywood is machined on one side as sawtooth, and the other side is sawtoothed (13a and 13b), and then joined together with an adhesive equal to or greater than the adhesive used to make the combination plywood to obtain the desired length. Can be. The manner in which the teeth and teeth engage with each other is called a finger joint. Finger joints may be vulnerable, so the connection part is installed with consideration to be placed in the anti-vibration rubber (12) position or yoke (13) position.

The floor board 15 uses maple, oak, birch, ash, etc. which are commonly used, but can reduce the thickness of the floor board by narrowing the gap between the joists that support the floor board 15. Since the most expensive material for flooring in athletic facilities is flooring, the adoption of athletic joists using combination plywood mats with excellent strength characteristics can reduce the thickness of the flooring, leading to a reduction in material costs.

6 is a perspective view, a plan view, and an elevation view as specific examples of the anti-vibration rubber adopted in the present invention. Anti-vibration rubber is adopted to satisfy the quality standards of floors for sports facilities against various loads on floor boards. The anti-vibration rubber used conventionally has a plate shape, and is inadequate to load.

The anti-vibration rubber used in the present invention has a circular or rectangular flat body 12a having a constant thickness, and a first protrusion protruding from the body 12a with a plane having a narrower thickness than the body 12a and having a constant thickness. 12b and a second protrusion 12c protruding from the first protrusion 12b and having a plane narrower than the first protrusion 12b and having a semi-circular shape. Since the second protrusion 12c has a semi-circular shape, the response to the load is quick, and the first protrusion 12b, the second protrusion 12c, and the body 12a work together to prevent dust and shock. It works.

The procedure for installing the floor for athletic facilities of the present invention will be described.

Since the concrete floor 1 may contain moisture, a moisture proof layer 2 is formed on the concrete floor 1 with a polyethylene film or the like. The pedestal 11 is installed on the moisture proof layer 2. On the moisture proof layer 2, a heat insulating sound absorbing layer 3 is provided with a glass surface, a rock surface or the like for heat insulating and sound absorption. The yoke 13 with the anti-vibration rubber 12 is disposed on the pedestal 11 and across the pedestal 11, and the yoke 13 is installed with the joist 14 across the yoke and the yoke 13. And the joists 14 are coupled to each other. And the floor structure is completed by installing the floor board 15 on the said joist 14. When the concrete floor 1 is often installed, the horizontality does not fall within the error range, so that the horizontal adjustment plate 17 may be installed between the pedestal 11 and the yoke 13 to adjust the height. In this case, the horizontal adjusting plate 17 is fixed at the same time with concrete nails when fixing the pedestal 11 to the floor.

The present invention provides a floor structure for a sports facility with little deformation of the structure according to the change of the indoor environment of the sports facility and can be used for the production of other products and to recycle the materials to be disposed of, thereby contributing to environmental protection.
