Description

Detailed Description of the Invention (a) Industrial Application Field The present invention relates to a floor system for large buildings such as arenas and gymnasiums, and more specifically, the present invention relates to a floor system for large buildings such as arenas and gymnasiums. Regarding equipment.

(b) Conventional technology In general, floor equipment in gymnasiums, etc., involves fixing support legs at predetermined intervals on a concrete slab, and then pouring a large tension material onto the support legs, and then placing the support legs on the support legs at right angles to the support legs. It is constructed by laying floor joists in the direction of the roof and placing flooring materials such as flooring boards on top of the joists. In addition, the support legs are equipped with adjustment bolts and cushioning materials such as rubber, which adjust the unevenness of the concrete slab and maintain a flat surface of the floor device, as well as maintain a specified elasticity performance necessary for movement and safety. Granted.

Conventionally, the elastic performance of floor equipment consists of a buffering effect that softens the impact received from the floor when landing during intense exercise, a repulsion effect that gives appropriate momentum to the exercise movement, and a vibration damping effect. It is specified by the spring characteristics of the cushioning material and the deflection characteristics of the large tension material, joist material, etc., and is generally evaluated by a value called the Y value calculated by the test method and calculation method specified by JIS. Ru.

(c) Problems to be solved by the invention In recent years, large buildings such as gymnasiums are sometimes used as venues for various events such as concerts, in addition to being used for regular exercise. Excessive weight acts on the floor due to the movement of heavy machinery such as forklifts to set up the venue, and the presence of a large number of people.

Therefore, a floor device that is also used as an event venue needs to be constructed in advance to be robust so as to be able to withstand excessive weight. As a result, the elasticity of the cushioning material and large tensioning material is impaired, resulting in a floor device that is hard to scrape and has poor elasticity.When used as a regular playground, sufficient exercise performance cannot be achieved, and the Achilles key may be damaged. This also poses safety problems, such as the risk of injury if the user falls and hits his or her head, elbow, etc.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a floor device that can sufficiently withstand excessive loads during events and the like, while also having sufficient elasticity and softness during normal exercise use. .

(d) Means for Solving the Problems The present invention has been made in view of the above-mentioned circumstances. For example, as shown in FIG. 1, a cushioning material (
In a flooring device (6) in which a joist decking member (3) is placed and fixed via the joist decking member (2a), and a floorboard (5) is further fixed on the joist decking member (2a), 3) is made of a highly rigid member that extends over substantially the entire floor surface, and includes the joist deck member (3) and the support portion (1).
A regulating member (7) for limiting the amount of deformation of the cushioning material (2a) is disposed between the cushioning member and the cushioning member.

(e) When used as a regular gymnasium based on the above structure,
The load caused by the athlete exercising on the floorboard (5) is:
It acts on the buffer material (2a) through the joist deck member (3) and is absorbed by the buffer material (2a). At this time, the regulating member (7) does not hit the support part (1) due to the load due to the exercise, and the cushioning material (2a) absorbs the impact due to the competition with its moderate elasticity and softness. On the other hand, when used as an event venue, if an excessive load is applied due to a heavy machine such as a forklift traveling on the floorboard (5), the load will be transferred to the cushioning material (2a) via the highly rigid joist deck member. However, the cushioning material (2a) is deformed by more than a specified amount due to the excessive load, and the regulating member (7) comes into direct contact with the support portion (1). Therefore, the excessive load is carried directly by the support portion (1) via the regulating member (7).

Note that the symbols in parentheses are for comparison with the drawings, but do not limit equivalent configurations.

(F) Examples Examples of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3, the flooring device 6 for large buildings such as main arenas has a concrete slab 10, on which support legs 12 are installed at predetermined intervals through base mortar 11. Fixed. The support leg 12 is made of steel, and includes a cylindrical member 12a of a predetermined length, a base plate 12b fixed to the lower surface of the cylindrical member, an upper plate 12c fixed to the upper surface of the cylindrical member, and fixed to the upper plate 12c. Two adjustment bolts 1 screwed into the oak)-12d, ], 2d
Consists of 2e and 12e. And the adjustment bolt 12e,
A large pull member 13 is adjustable and fixed to 12e by an upper nut 15.15 and a lower nut 16.16. The large pull member 13 includes an H-shaped steel 13a and a lower surface a of the H-shaped steel.
It consists of a reinforcing flat plate 13b fixed to the upper plate of the H-shaped steel 13a, and a buffer member 2 is fixed to the upper plate of the H-shaped steel 13a. The buffer member 2 consists of a buffer material 2a such as rubber, a lower plate 2b baked and fixed to the lower surface of the buffer material 2a, and an upper plate 7 baked and fixed to the upper surface of the buffer material.

The upper plate 7 is made of a steel plate having a U-shaped cross section with both sides thereof bent, and the bent portions 7a, 7a are in contact with the lower plate 2b, thereby being a regulating member that limits the amount of deformation of the cushioning material 2a. It consists of Further, a joist deck member 3 is fixed to the upper surface of the regulating member 7, and the joist deck member 3 is made of a wide member made of a damping steel plate bent into a trapezoidal wave shape, and extends over almost the entire floor surface. will be established. Then, the joist deck member 3
A flooring material 5 made of plywood 5a, a surface material 5b, etc. is fixed to the upper surface 3a.

In addition, in FIG. 3, 20 is a base for physical education equipment for installing a ball for a net, etc.

The construction method for the main floor covering W6 will now be explained.

At a predetermined interval on the concrete slab 10 (for example, 1
, 800mm), the base plate 12b of the support leg 12 is placed at predetermined intervals (for example, 2.400mm).
Anchor bolts 17.17 through base mortar 11
and fixed by nuts 19.19. After all the support legs 12 are fixed, the large tension member 13 is flown onto these support legs 12 along the marked lines, and the nuts 15 and 16 screwed into the adjustment bolts 12e and 12e are adjusted. By doing so, the height is adjusted to a predetermined level. As a result, the supporting portion 1 is constructed which is extremely strong and has high rigidity. The buffer member 2 is disposed on the upper part of the support leg 12 on the large pull member 13 by fixing its lower plate 2b with adhesive or screws, and furthermore, the upper plate 7 of the buffer member 2 is provided.
On top, the bottom surface 3b of the joist deck member 3 is fixed over substantially the entire floor surface with adhesive or screws. Furthermore, after that,
On the upper surface 3a of the joist decking member 3, a plywood board 5a and a surface material 5b are fixed with screws and adhesive.

Since this embodiment has the above-described configuration, when used as a normal gymnasium for sports and competitions, the impact and momentum generated when athletes perform athletic movements on the floorboard 5 are transmitted through the joist deck member 3. This is absorbed by the shock absorbing member 2, and exercise motion can be performed satisfactorily due to its moderate elasticity. Furthermore, if the player falls for some reason and hits his head, elbow, knee, lower back, etc., the cushioning member 2 bears the impact with appropriate softness. In addition, at this time, the impact that is caused by the engineer i and that acts on a point on the floor board 5 is spread over the area by the joist deck member 3, which has high rigidity and is spread over almost the entire floor surface. and the buffer member 2 is attached to the surface portion.
Therefore, no matter where it is on the floorboard 5,
Approximately the same elasticity and softness performance is maintained.

On the other hand, when used as an event venue, a forklift or the like runs on the floorboard 5, and a large number of people are accommodated, so a large load acts on the floorboard 5. Then, the large load is received by the highly rigid joist deck member 3,
Then, it acts in a distributed manner on a large number of buffer members 2 over a wide area, deforming the buffer material 2a in the corresponding portion by a predetermined amount or more. As a result, the bent portions 7a, 7a of the regulating member 7 come into contact with the lower plate 2b, preventing further deformation of the cushioning material 2a, and the large load acting on the deck member 3 is transferred through the regulating member 7. It acts directly on the large pull member 13 and is supported by the support portion 1 consisting of the large large pull member 13 with high rigidity, support legs 12, and the like.

Next, the elasticity performance test for the above-mentioned floor device will be described.

The elastic performance test is conducted by freely dropping a weight of a predetermined weight from a predetermined height and measuring the resulting deformation and damping characteristics of the floor (JISA-6519). The maximum amplitude of the floor vibration is (mm), the apparent half period T at the maximum amplitude of the floor vibration, I (sec), and the amplitude of the floor vibration is 0.
．． Time required to attenuate to 2 (mm) T V-D
(sec), and the floor deformation energy U r (Kg - cm) until the floor deformation reaches the maximum, and by calculating these values according to the calculation formula specified in JIS, the elasticity value is calculated. Y and the buffering effect value U are obtained. The elasticity value Y preferably has a maximum value of 0.0 or more and a minimum value of -0.2 or more, and the buffering effect value U preferably ranges from 15 to 40.

As shown in FIG. 7, the above-mentioned elasticity value Y and The buffering effect value U is shown in Table 1.

Based on the above results, the cushioning effect value U is slightly hard, but the elasticity value Y is at the optimal value, and there is almost no difference between the measurement points, and it is almost uniform over the entire floor surface and is optimal. It can be seen that it can exhibit excellent elasticity performance.

Further, with reference to FIGS. 4 and 5, an embodiment will be described which is suitable for application to buildings smaller than the above-mentioned embodiments, such as gymnasiums.

In the floor device 6' in this embodiment, the support legs 12 are connected to a cylindrical member 12a, a base plate 12b, an upper plate 12c, and one adjustment bolt 12e screwed onto a nut 12d fixed to the upper plate. Also, the large tension member 13 is made of a steel material with a cross-sectional shape, and the large tension member 13 passes through the adjustment bolt 12e and is fixed on its upper and lower surfaces by nuts 15 and 16. Then, the buffer members 2 and the regulating members 7 are fixed at appropriate intervals on the main tension member 13, and the joist deck member 3 is laid over the entire floor on the regulating member 7, and the board material 5 is stretched on top of it. ing.

Next, an embodiment partially modified according to FIG. 6 will be described.

In the above-mentioned embodiment, the location where the buffer member 2 and the regulating member 7 are installed is limited to correspond to the bottom surface 3b of the joist deck member 3. For this reason, if marking is done on the large tension member 3 over the entire wide floor surface and the buffer member 2 is fixed to the marked place, the bottom surface 3b of the deck member 3 and the buffer member may be 2 may be misaligned. Therefore, it may be necessary to use an implementation method with low work efficiency, such as fixing the buffer member 2 at a predetermined location for each joist deck member to be placed.

Therefore, in the floor device 6'' of this embodiment, a regulating member 7 made of a long steel plate having a U-shaped cross section is fixed by flowing it over a large number of cushioning materials 2a and along the tension member 13. Thereby, the trapezoidal wave-shaped joist decking member 3 can fix the bottom surface 3b at any position on the elongated regulating member 7 and work efficiently, regardless of the installation position of the buffer member 2.

In addition, although the long regulating member 7 was used in the above embodiment, the short regulating member shown in the previous embodiment was used, and a long intermediate member made of flat steel or the like was poured over the regulating member. It's okay.

Further, as the support part 1, the support leg 12 and the large pull member 13 are used, but the large pull member 13 may be poured directly onto the concrete slab via a platform member without using the support leg 12. Furthermore, the buffer member 2 may be installed directly via the base member.

(G) As described in detail, according to the present invention, when used for normal athletic events, appropriate elastic performance and softness performance based on the cushioning material (2) can be obtained, and sufficient athletic movement can be achieved. However, when used as an event venue, even if an excessive load is applied to the floor equipment due to carrying in heavy objects or accommodating a large number of people, The highly rigid joist decking member (3) and regulating member (7) extending over almost the entire surface of the floor directly apply a load to the supporting portion (1), so that the load can be sufficiently withstood.

In addition, a vibration-damping steel plate having a trapezoidal wave shape can be used for the joist deck member (3), which can reduce the generation of noise caused by the impact acting on the floor equipment and the propagation of vibration to the floor ring. can.
