Description

Detailed Description of the Invention (a) Industrial Application Field The present invention relates to a floor system for large buildings such as gymnasiums and arenas where athletics can be held on the floor. This invention relates to a construction type floor device which is assembled and a flooring material is laid thereon.

(b) Conventional technology In general, a construction type floor system for gymnasiums etc. fixes support legs at predetermined intervals on a concrete slab, then pours a large tension material onto the support legs, and then pours a large tension material onto the support legs. It is constructed by passing floor joists in a direction perpendicular to this, and then covering them with flooring materials such as flooring boards. 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 By the way, conventional assembly type floor devices have cushioning materials such as cushion rubber or cushion springs interposed in the support legs.
It is possible to design a certain part of the floor so that the elastic performance is within the optimal range, but the elasticity may vary widely over the entire floor, for example in the middle of the floor joists and large timbers. Even if it has the optimum elastic performance, it exhibits extremely hard elastic performance at the intersection of the joists and the main lumber.

In addition, taking into consideration the deflection characteristics of the joists and large joists, the distribution of the supporting legs with cushioning materials, large joists, and joists is defined in a predetermined relationship, so that the distribution is approximately uniform over the entire floor surface. In this case, the spring characteristics of the cushioning material and the deflection characteristics of the joists and large tension materials are interrelated depending on the load location, so there is considerable variation in the elastic performance. Although it is improved, it is not enough.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a floor device that imparts substantially uniform elasticity to all parts of the floor covering and has comfortable exercise performance.

(:) Means for Solving the Problems The present invention has been made in view of the above-mentioned circumstances. For example, as shown with reference to FIG. 1, concrete slabs (10

), the flooring device (A) has a cushioning member (2) identified on the support portion (1).
), and a highly rigid joist deck member (3) fixed on the buffer member and extending over substantially the entire floor surface, the joist deck member (3) absorbs the impact acting on the flooring.
), the material is diffused and planarized, and then absorbed by the buffer member (2).

(f) Effect Based on the above configuration, the load that acts on the floorboard (5) due to the athlete's exercise is diffused by the highly rigid joist deck member (3) and acts over the area, resulting in a large number of I They are distributed and supported by the impact member (2). As a result, the impact load caused by the athlete is received by the buffer member (2) with appropriate elastic performance, and based on the action of the buffer member (2) that directly receives the load from the joist deck member (3). The elastic performance described above acts almost uniformly on all parts of the floor surface, allowing athletes to perform good athletic movements.

Note that the reference numerals in parentheses are for contrast with the drawings, and do not limit the structure in any way.Examples Hereinafter, embodiments of the present invention will be described along with the drawings.

A floor system 6 for a large building such as a main arena is supported by a subfloor bag HA assembled on a concrete slab 10, as shown in FIGS. 1 to 3. The subflooring device A has support legs 12 fixed to the concrete slab 10 via base mortar 11 at predetermined intervals, and the support legs 12 are made of steel and are made of cylindrical members of a predetermined length. 12a, a base plate 1 fixed to the lower surface of the cylinder member;
2b, an upper plate 12c fixed to the upper surface of the cylindrical member, and two adjusting bolts 12e, 12e screwed into nuts 12d, 12d fixed to the upper plate 12c. and,
A large pull member 13 is adjustable and fixed to the adjustment bolts 12e, 12e by an upper nut 15.15 and a lower nut 16.16. The large pull member 13 is an H-shaped steel 13
a and the reinforcing flat plate 13 fixed to the lower surface a of the H-shaped steel
b, and a buffer member 2 is fixed on the upper plate of the H-shaped $13a. The buffer member 2 is made of M such as rubber.
It consists of a hit 2a, a lower plate 2b baked and fixed to the lower surface of the cushioning material 2a, and an upper plate 7 baked and fixed to the upper surface of the cushioning material. The upper plate 7 is made of a steel plate having a U-shaped cross section with both sides bent, and is a regulating member that limits the amount of deformation of the cushioning material 2a by coming into contact with either the bent portions 7a, 7a or the lower plate 2b. 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. A floor material 5 made of plywood 5a, a surface material 5b, etc. is fixed to the upper surface 3a of the joist deck member 3.

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

Next, a method of constructing the main floor device 6 will be explained.

At a predetermined interval on the concrete slab 10 (for example, 1
, 80C) a+m), the base plate 1 of the support leg 12 at predetermined intervals (for example, 2,400 mm).
2b is connected to the anchor bolt 17 through the base mortar 11.
17 and nuts 19, 19. and,
After all the support legs 12 are fixed, these support legs 12
The large pull member 13 is flown upward along the marking line, and the nuts 15 and 16 are screwed onto the adjustment bolts 12e and 12e.
By adjusting the height, the height is adjusted to a predetermined level.

As a result, the supporting part 1 is constructed which is extremely strong and has high rigidity. Then, 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 further on the upper plate 7 of the buffer member 2. In this case, the bottom surface 3b of the joist deck member 3 is fixed over substantially the entire floor surface with adhesive or screws. As a result, the support leg 12, the large pull member 13, &! A subfloor system A consisting of the shock members 2 and the joist deck members 3 is assembled. Furthermore, thereafter, the plywood 5a and the surface material 5b are fixed on the upper surface 3a of the joist deck member 3 with screws and adhesive, thereby forming the floor device 6.

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 floorboards 5 are transmitted through the joist deck members 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 caused by the athlete that acts on a point on the floorboard 5 is absorbed by the joist deck member 3, which has high rigidity and is spread over almost the entire floor surface.
Since it is diffused over a surface area and absorbed by the buffer member 2 in the surface area, substantially the same elastic performance and softness performance are maintained regardless of the position on the floorboard 5.

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.

In this regard, the elastic performance test for the above-mentioned floor equipment will be described.

The elastic performance test is performed by dropping a weight of a predetermined weight freely from a predetermined height and measuring the resulting deformation and damping characteristics of the floor (JISA-65, 19), and the maximum amplitude of the vibration of the floor. (mm), the apparent half period T* (sec) at the maximum amplitude of floor vibration, and the amplitude of floor vibration 0.
The time required to attenuate to 2 (am) TV, D (se
c), and the deformation energy Ur (Kg-cm) of the floor until the deformation of the floor reaches the maximum are measured, and by calculating these values according to the calculation formula prescribed in JIS, the elasticity value Y and A buffering effect value U can be obtained. and,
The elasticity value Y has a maximum value of 0.0 or more and a minimum value of -0.2
It is desirable that the buffering effect value U is 15 or more.
-40 is desirable.

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.

As for the floor device 6' in this embodiment, the support leg 12 includes 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. Further, 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 the upper and lower surfaces thereof with nuts 15 and 16. The buffer members 2 fixed at appropriate intervals on the large tension member 13 are composed of a buffer material 2a such as rubber, a lower plate 2b, and an upper plate 2C, and as in the previous embodiment, the upper plate constitutes a regulating member. It is made of simple flat steel.

Furthermore, a joist deck member 3 similar to that of the previous embodiment is laid over the entire floor on the buffer member 2, thereby assembling the subfloor system A'.

A plate material 5 is stretched over the joist deck member 3 of the flooring device A', thereby forming a flooring device 6'.

Therefore, in the main floor device 6', although the restricting member does not have the effect of restricting the deformation of the cushioning material 2a, the load exerted by the player is uniformly absorbed over the entire floor surface, as in the previous embodiment.

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

In the above 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 location, due to errors in the deck member 3, the bottom surface 3b of the deck member 3 and the buffer member 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, the intermediate member 21 made of a long steel plate is fixed by flowing it over a large number of cushioning materials 2a and along the large tension member 13. The joist deck member 3 can be placed on the bottom surface 3b at any position on the long intermediate member 21 regardless of the installation position of the buffer member 2.
can be fixed and work can be done efficiently.

In addition, although the above-mentioned embodiment uses the support #12 and the large tension member 13 as the support portion l, this is because the large tension member 13 is directly mounted on the concrete slab via the base member without using the support legs 12. Alternatively, the buffer member 2 may be installed directly via a base member.

(g) As described in detail, according to the present invention, the point-like impact load acting on the floorboard (5) is reduced by the highly rigid joist deck member (
3), and the load is received by the multiple buffer members (2) intermittently, so it is possible to exhibit substantially uniform elastic performance over all surfaces of the floor device. The athletic movements of the athlete can be well maintained over all sides of the floor device.

Furthermore, since the highly rigid joist deck member (3) is used,
A robust floor system can be obtained, and a joist deck member (3) made of a trapezoidal wave-shaped vibration-damping steel plate can be used to prevent noise generation due to impact acting on the floor system and vibrations to the downstairs etc. It is possible to reduce the propagation of
