Description

  The present invention relates to a floor structure that reduces noise caused by vibration and has sufficient strength, and more particularly to a floor structure that can be used in a parking lot.

In general, iron materials are used as materials for various structural materials because of their high strength. And when using in a parking lot and a bicycle parking lot, for example, there is an example of using these flooring materials using steel flooring materials.
In addition, many steel materials are used for beams, wall surfaces and the like as structural materials for steel houses and the like that have been proposed in recent years. However, in the technique according to Patent Document 1, the floor surface of the second floor or more does not use joist. It is composed of steel beams, and a floor panel is installed between the beams.
As the floor structure, steel ones are heavy, and wooden ones are widely used because of production costs.

However, parts that are heavy, such as parking lots, may need to be made of steel.
For example, as shown in FIGS. 8 and 9, there is a conventional technique as a material used for a steel flooring in a parking lot or the like. A sectional view of the floor material is shown in FIG. 8, and a perspective view of the usage state is shown in FIG.

In the above-mentioned conventional technology, it seems that it is used for flooring of parking lots, bicycle parking lots, flooring of factories, etc., but when using these uses, especially flooring of parking lots, flooring. In the case of a steel plate material processed by punching or the like, there is a problem that the tire slips on the unevenness formed by the mold. That is. When the uneven shape is a shape that provides a pattern used for a striped steel plate, the corners of this convex part are rounded, and it seems that the tire is slippery just by reducing the ground contact area of the tire It is.
In addition, it is effective when a hole is drilled, but when the hole is opened to a size that attempts to prevent slipping sufficiently, the strength will decrease, and parking floor materials It's not optimal.

Moreover, when it is used outdoors as it is, water is expected to accumulate in the receiving portion 80 of the floor material 8, and there is a possibility that a problem arises in corrosion resistance.
Furthermore, the floor material 8 is fixed with beams or floor materials with bolts and nuts, etc. However, when vibration is applied to the floor material 8, vibration cannot be absorbed between the floor materials 8, so noise is generated. It may occur.

Also, in the case of a steel plate material processed by punching or the like as a flooring material, the unevenness formed by the mold is not effective for the problem that the tire slips, and it is effective when a hole is made, but the hole is made. If the hole is opened to a size that is sufficient to prevent slipping, the strength will decrease, and it is not optimal as a parking lot flooring.
The present invention provides a floor structure that has strength, can prevent noise generation, has excellent corrosion resistance even after long-term use, and is simple in structure and can be produced at low cost. .

The floor structure is composed of a member and a cushioning member provided on both sides of the floor surface constituent part, and the plurality of floor surface constituent members provided in parallel placed on the base member have a lip portion at the opening below The fixing member that is placed on the base member so as to fix the floor surface constituent part to the base member is an angle, channel material, etc. provided above the lip part so as to sandwich the lip part of the floor surface constituent member The internal fixing member made of a material that does not deform is fixed between the base member and the cushioning member provided on both sides of the floor surface component member is at least on both sides of the floor surface component member provided with the fixing member. It is characterized by being provided in close contact with the lower end of the base member side.

And it is preferable to provide a waterproof structure member on the upper part of the cushioning member provided on both sides of the floor surface component member. Furthermore, as the waterproof structure member, the upper part of the cushioning member has a size slightly larger than the width of the buffer member. In addition, the foamed polystyrene having the same length as the length of the floor surface constituent member is placed while being crimped and sandwiched between the floor surface constituent members so as to be crushed, and a waterproof material is filled into the gap above the foamed polystyrene from above. It is preferable to do.

It consists of a buffer member provided on the side and has a floor structure. By using the floor surface constituent member having the cross-sectional shape of this C-shaped steel, it can also be used for a portion where a large load is applied. The floor surface component is placed on the foundation member so that the lip portion of the opening is downward, and the fixing member that fixes the floor surface component to the foundation member is the lip portion of the floor surface component. Since it is configured to be fixed so as to be sandwiched, when a stress such as a load is applied to the floor surface component member, the stress is applied in the direction in which the lip portion of the floor surface component member having a C-shaped steel cross-sectional shape opens However, since the cushioning members provided on both sides of the floor surface component are provided, this stress is quickly absorbed. Therefore, the vibration generated when a load is applied to the floor constituent member is quickly attenuated, and the present invention has a silencing effect.

In addition, since a waterproof structure member is provided above the cushioning member, it is possible to prevent the intrusion of water from the floor surface to the inside of the floor surface component, thus eliminating the cause of corrosion inside. It can be used for a long period of time, and even if this floor structure is used for a floor structure of a parking lot installed outdoors, it can be used for a long period of time. Furthermore, the present invention does not require the work of forming a material such as a steel plate, and can be used by cutting a commercially available C-shaped steel into a predetermined length.

The floor structure of the present invention includes a base member 1, a plurality of floor surface constituent members 2 provided in parallel placed on the base member 1, and a fixing member 3 that fixes the floor surface constituent member 2 to the base member 1. The cushioning member 4 is provided on both sides of the floor constituting member 2, and the waterproofing structural member 5 is further disposed above the cushioning member 4.
Hereinafter, these will be described with reference to the drawings.

<Base member 1>
The base member 1 is the foundation of the floor structure, and is made of a strong material and shape. The one shown in FIG. 1 uses a channel material. H-shaped steel or the like is used depending on the application. In principle, steel is used, but it goes without saying that other materials may be used as long as they have strength.

<Floor component 2>
The floor surface component 2 has a C-shaped steel cross-sectional shape, the opening 20 faces downward, and the lower lip 21 is placed on the upper surface of the foundation member 1. And the side surface of the floor surface component 2 is the side surface portion 22, and the upper surface is the floor surface 23.
Since the upper surface of the floor surface component 2 is the floor surface 23, it is preferable to perform plating or the like in consideration of corrosion resistance, decorativeness, and the like.

<Fixing member 3>
The fixing member 3 is used when fixing the floor constituent member 2 to the base member 1, and includes a fixing member 30 made of, for example, an angle, a channel material, or the like that does not cause deformation, and a high tension bolt nut 31. To do.
As shown in FIGS. 2 to 4, the fixing member 3 is inserted into the opening 20 of the floor surface component 2, and the lip portion 21 of the floor surface component 2 is sandwiched between the top surface of the base member 1. Then, it is fixed with a high tension bolt nut 31.
Although the high tension bolt nut 31 is preferably used as the fixing member 3, a high strength section bolt nut may be used instead of the high tension bolt nut 31 in some cases.

<Buffer member 4>
The buffer member 4 is made of a hard buffer material, and for example, hard synthetic rubber can be used. The shape is a gap α1 (see FIG. 3) between the floor constituent members 2, for example, a plate having a thickness of about 5 mm, and the length is about the width of the base member 1. And it is set as the structure which provides the buffer 40 of the buffer member 4 in the side surface part 22 of each floor surface structural member 2 which fixes the floor surface structural member 2 to the base member 1 at the base member 1 side. And this buffer body 40 is provided between each side surface part 22 of the adjacent floor surface structural member 2, and is provided so that it may contact | adhere.

  The buffer body 40 is provided on the base member 1 side because the floor surface component 2 has a cross-sectional shape of C-shaped steel, and the base member 1 side, that is, the side surface portion 22 of the floor surface member 2 is provided. By providing on the lower end side, a stress acts so that the lower end side opens when a load is applied to the floor surface component 2, and this stress is quickly buffered to act to absorb vibration.

The buffer member 4 is set to be equal to the width of the gap between the floor surface constituent members 2 or slightly wider than the gap, and the buffer member 4 is slightly compressed at the time of construction, so that the degree of adhesion is increased. It is preferable to do. For example, when C-shaped steel is used for the floor surface component 2 and is plated, when the thickness of the plating is 30 to 50 μm, the two side surfaces are narrowed by 60 to 100 μm, corresponding to the plating. Therefore, a force is applied to the side surface portion 22 of the floor surface constituent member 2 inward by this narrowing, so that the buffer member 4 and the floor surface constituent member 2 are always configured to increase the degree of adhesion.

<Waterproof structure member 5>
The waterproof structural member 5 is provided in the gap between the floor surface constituent members 2 installed adjacent to each other to prevent intrusion of water or the like. Above the buffer member 4, the rod-shaped foamed polystyrene 50 and the waterproof filler 51 are provided. Is provided. The rod-shaped foamed polystyrene 50 is larger than the gap between the adjacent floor surface constituent members 2 described above. For example, if the gap is 5 mm, a columnar one of about 7 mm is used. The length is equal to the length in the longitudinal direction of the floor surface component 2. As shown in FIGS. 3 and 4, the rod-shaped foamed polystyrene 50 is interposed so as to be crushed in the gap between the side surface portions 22 of the floor surface constituting member 2, and is used so as to enhance the waterproof effect.

The waterproof filler 51 uses, for example, silicon resin, but the material is not limited as long as it can be waterproofed. However, since the silicon resin is in close contact with the side surface portion 22 of the floor surface constituting member 2 similarly to the buffer member 4 described above, it can also have a function of reducing the occurrence of vibration.
In addition, the above-mentioned waterproof structure member 5 is used outdoors, and this waterproof structure member 5 can be omitted when there is no problem in dropping water or the like below.

Next, the outline of manufacture of this invention is demonstrated easily based on FIGS.
As shown in the figure, an internal fixing member 30 is inserted into the inside of the front end side of the floor surface component 2 and fixed to the base member 1 with a high tension bolt nut 31. Similarly, it fixes to the base member 1 in the three places of the rear end side of the floor surface structural member 2, and an intermediate part, and fixation of one floor surface structural member 2 is completed.
In this fixing, the mounting holes of the base member 1 and the fixing member 3 are set to be slightly larger than the high super strength bolt nut 31. For example, when M12 high super strength bolt nut 31 is used, the mounting hole is φ14 mm. The buffer member 4 is attached between the floor constituent members 2 with a margin of about 2 mm so that the work can be performed with a high degree of adhesion.

Next, the buffer body 40 of the buffer member 4 is placed on the side surface portion 22 of the floor surface component 2 on the foundation member 1, and the rod-shaped foamed polystyrene 50 is placed on the upper portion of the buffer body 40, and the next floor surface component member 2 is foundationed. Place on member 1. The fixed floor surface component 2 assembled to the placed floor surface component 2 is pressed against the buffer member 40 so that the shock absorber 40 is brought into close contact with the side surface portion 22 of the floor surface component 2 so as to crush the rod-shaped foamed polystyrene 50. In this state, the internal fixing member 30 is inserted into the floor surface constituting member 2 and the high tension bolt nut 31 is screwed and fixed.
Similarly, by fixing the rear end side and intermediate portion of the floor surface component 2 to the base member 1, the buffer member 4 and the rod-shaped foamed polystyrene 50 are fixed between the two floor surface components 2.

Thereafter, these steps are repeated to complete the assembly of the floor structure in which all the floor surface constituent members 2 are assembled and fixed to the base member 1 with the buffer member 4, the styrofoam 50 and the like interposed therebetween.
Next, a waterproof filler 51 made of silicon resin or the like is injected into the upper part of the rod-shaped foamed polystyrene 50 to complete the assembly operation.

In FIG. 1, five examples of the floor surface component 2 are shown. However, it is considered that a single unit is manufactured and a plurality of the same members are combined and used in combination so that a tatami mat is laid. However, in this case, it is necessary to interpose a combination of the buffer member 4 and the waterproof structure member 5 at each end.
In addition, it is needless to say that a large number of floor surface constituting members 2 can be manufactured at a time according to the purpose unlike the above embodiment. In this case, naturally, the number of the base members 1 is increased. Needless to say, making it.

The present invention is configured as described above,
The floor structure of the present invention is based on a base member 1, a floor surface constituent member 2 composed of a plurality of C-shaped steel cross-sections placed on and parallel to the base member 1, and the floor surface constituent portion 1. The floor structure is composed of a fixing member 3 fixed to the member 1 and a buffer member 4 provided on both sides of the floor surface constituting member 2.
Since the floor surface constituting member 2 having the cross-sectional shape of the C-shaped steel is used, it can also be used for a portion where a large load is applied. And the floor surface structural member 2 is mounted on the base member 1 so that the lip | rip part 21 of the opening part 20 may become downward.

  Here, the fixing member 3 that fixes the floor surface constituent member 2 to the base member 1 is formed by replacing the internal fixing member 30 provided above the lip portion 21 with the base member so as to sandwich the lip portion 21 of the floor surface constituent member 2. It is set as the structure fixed between. Therefore, when a stress such as a load is applied to the floor surface component 1, the lip portion of the floor surface component made of a C-shaped steel cross section is not firmly fixed by welding or the like. Since they are fixed in a sandwiched manner, when stress is applied in the direction of opening the lip portion 21, the stress acts to escape in the lateral direction.

  At this time, since the buffer members 4 provided on both sides of the floor surface component 2 are provided, this stress is quickly absorbed. Therefore, the vibration generated when a load is applied to the floor constituent member can be quickly damped.

Moreover, since the waterproof structure member 5 is provided in the upper part above the buffer member 4, it is possible to prevent water from entering from the floor surface to the inside of the floor surface component member. The floor structure can be used for a long period of time even if it is used for a floor structure of a parking lot installed outdoors.

The material floor surface constituting member 2 is assembled on the base member 1 by the method described above using 25 pieces of C-shaped steel (200 mm × 75 mm × 20 mm length 6800 mm, thickness 3.2 mm).
As the fixing member 3 of the fixing member 3, angle steel (65 mm × 65 mm thickness 8 mm) is used, and an M12 high-tensile bolt nut 31 is used.
The buffer member 40 of the buffer member 4 is made of synthetic rubber (40 mm × 100 mm × 5 mm), the rod-shaped foamed polystyrene 50 of the waterproof structure member 5 is 7 mm in diameter and 6800 mm in length, and the waterproof filler 51 is made of silicon resin. .
In the figure, 7 is a car stop.

This was used for parking. It was waterproof enough and there was no water entering the pit. Moreover, as shown in FIG. 5, the floor surface component 2 is provided in a direction perpendicular to the parking direction of the car. By providing the floor constituent member 2 in this direction, the length of the ground contact portion of a car tire is usually about 100 mm. In the above embodiment, the clearance 5 mm + the round portion 6 of the floor constituent member 2 .Alpha.2 = 5 + 6.4 + 6.4 = 17.8 mm shown in FIG. 3 and the anti-slip effect can be obtained.
If the gap is adjusted in consideration of the diameter of the tire, the inclination of the floor surface, etc., it is more effective as an anti-slip.

Moreover, the following experiment was conducted in order to confirm the above-mentioned effect with the prior art.

As shown in the figure, three pieces of rubber cushioning members 4 each having a size of 50 mm × 50 mm × 5 mm were fixed to the base member 1 made of H-shaped steel with the fixing member 3 described above. In addition, the waterproof structure member 5 was not provided in this invention product of this experiment.
As a comparative example, a noise test was performed by fixing four pieces of the product shown in FIG. 8 having a length of 150 mm, a length of 600 mm, and a height of 50 mm to the same base member 1 with bolts and nuts.
The measurement method of the noise test shows the results of using the method of measuring the radiated sound when a standard weight floor impact source (ball) is dropped from a height of 1 m above the floor board, as shown in Table 1 below.

As shown in Table 1, in the floor surface component according to the present invention, a difference of 5.1 dB occurs as compared with the conventional product, which has a significant silencing effect.

Next, using the same product as that subjected to the noise test described above, a static frictional force test was performed in order to achieve an anti-slip effect.
As a measuring method, a fixed tire loaded with a load of 500 KG was placed on the floor of each of the two products of the present invention and the comparative example, the withdrawal was measured, and the static friction force was measured.
