Description

  The present invention relates to a double floor structure formed by laying a plurality of floor panels on a floor base.

  As a double floor structure as described above, one having leg portions for receiving a square floor panel spaced above a floor base is conventionally known. In this double floor structure, it has also been proposed that a cushioning material is interposed between a floor panel formed of a rigid material and a floor base so as to improve shock absorption during a fall.

  Further, in a directly pasted floor finish material different from the above configuration, in order to improve shock absorption at the time of falling, for example, according to Japanese Patent Application Laid-Open No. 2003-268960, a hard surface material as shown in FIG. A technique has been proposed in which a cushioning body (cushion material) 102 is disposed under 101.

  However, according to this configuration, if the shock absorber 102 is too thick, the walking sensation may be uncomfortable, and if the shock absorber 102 is too thin, not only the unevenness of the ground floor is deteriorated, but also children and the elderly It is assumed that the impact when the etc. falls can not be absorbed and mitigated. Therefore, the danger increases in the event of a fall. According to the above technique, it is considered that the buffer body 102 has a temporary effect due to the use of two types of the buffer body 102. However, when the buffer property is adjusted in accordance with the use environment, the thickness of various types It is not sufficient because it is necessary to prepare different buffer bodies 102 such as.

By the way, according to a report presented at the Japan Geriatrics Society, as a result of a one-year survey at a nursing home, 26 out of 86 residents were over 30%. . In many cases, when a person falls, he breaks his bones. Accordingly, it has been proposed to lay a cushion mat (see JP 2000-238158 A) on the floor or the like. However, since the surface strength is insufficient, the wheel is buried by operation of a wheelchair or a moving bed, and is difficult to move. The occurrence of problems such as these is assumed. In other words, for example, in a hospital where nursing for the elderly is carried out, a sufficient amount of surface strength is ensured when a wheelchair or a moving bed is frequently used in the daytime, and there are few people walking other than the elderly with dementia unpacking. In the case of nighttime, the surface is buffered, the surface strength is such that the walking sensation does not deteriorate when people walk, and the shock-absorbing property is such that fractures and other injuries are not likely to occur even if an elderly person falls down. It is necessary to ensure. However, it is considered practically difficult to satisfy these requirements.
JP 2003-268960 A JP 2000-238158 A

  The present invention has been made in view of the above-described background art and needs, and the problem is that when high surface strength is required, the surface strength of a normal floor panel is ensured, and in other cases, shock absorption is achieved. The object of the present invention is to provide a double floor structure in which the buffering property can be adjusted according to the use environment.

  In order to solve the above problems, a double floor structure according to the present invention is a double floor structure formed by laying a plurality of floor panels on a floor base, and the floor panel is a flexible plate material. A main leg portion is suspended from the periphery of the plate member, and an auxiliary support portion having an adjustable length that is shorter than the main leg portion is provided on the inner side of the plate member. It is possible to adjust the gap.

  And it is preferable to form the said auxiliary | assistant support part in the cylinder which can be externally controlled by an electric or hydraulic adjustment etc., and to carry out the adjustment control of the said clearance gap of the several thing of the said floor panel collectively.

  It is also preferable to interpose a planar cushion material in the space between the main leg portion and the auxiliary support portion.

  According to the double floor structure of the present invention, by adjusting the gap between the auxiliary support part and the surface of the floor base, if a high-strength floor surface is required, the length of the auxiliary support part is increased. If the strength of the floor material is secured and high strength is unnecessary, it is possible to shorten the length of the auxiliary support part and adjust the deflection of the floor surface by the floor panel to increase the shock absorption. Therefore, it is possible to provide a double floor structure in which the buffering property can be adjusted according to the use environment.

  And, the auxiliary support part is formed by a cylinder that can be controlled externally by electric or hydraulic adjustment, etc., and the clearance of the plurality of floor panels is adjusted and controlled in a lump. It is easy to adjust the cushioning of the floor according to the time zone.

  Moreover, since the planar cushion material is interposed in the space between the main leg portion and the auxiliary support portion, it is possible to prevent excessive bending over the entire floor panel.

In order to clarify the features and advantages, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

  Referring to FIG. 1, there is shown a schematic configuration diagram of an installation state of a single floor panel having a double floor structure according to an embodiment of the present invention.

  This double floor structure is a double floor structure formed by laying a plurality of floor panels 2 on a floor base 1, and the floor panel 2 has a main leg around a flexible plate 3. A portion 4 is vertically provided, and an auxiliary support portion 5 having an adjustable length that is shorter than the main leg portion 4 is provided inside the plate member 3. The auxiliary support portion 5 and the surface of the floor base 1 are provided. The gap between and can be adjusted.

  Further, the auxiliary support portion 5 is formed by a cylinder 52 which can be controlled externally by electric or hydraulic adjustment, and the gaps of a plurality of floor panels 2 are adjusted and controlled collectively. Further, a planar cushion material 6 is interposed in the space between the main leg portion 4 and the auxiliary support portion 5.

  Specifically, the floor panel 2 has a main leg portion 4 suspended around a plate material 3 formed of a plywood having a square shape of about 50 cm and a thickness of about 15 mm having flexibility, An auxiliary support portion 5 whose length can be adjusted is disposed substantially at the center of the plate member 3. In this case, a rectangular of a predetermined size is provided so as to cover substantially the entire surface of the floor panel 2 with the auxiliary support portion 5 interposed therebetween. The cushion materials 6 and 6 are formed so as to be interposed between the slab surface serving as the floor foundation 1 and the plate material 3.

  As shown in FIG. 2, on the back surface of the plate material 3, an auxiliary support portion to be described later that supports the plate material 3 in the middle with a height lower than the main leg portion 4 along the center line of the plate material 3 between two opposite sides. A plate-shaped reinforcing beam 51 forming 5 is suspended and fixed by screws. Further, as shown in the figure, the main leg portion 4 has a square columnar body hanging down around the back surface of the plate material 3 and screwed so as to support the plate material 3 on the outer periphery.

  In addition, although this board | plate material 3 has shown the square, this invention is not limited to it. The size of the floor panel 2 is preferably about 25 to 80 cm on one side. When one side of the floor panel 2 is less than 25 cm, the ratio of the area of the main leg 4 to the total area of the floor panel 2 becomes large, and it becomes inefficient considering the purpose of this double floor structure. . In addition, when one side of the floor panel 2 is 80 cm or more, when the auxiliary support portion 5 does not act and the floor panel 2 becomes weak and the person walks, the floor is bent too much and the walking feeling increases and the walking feeling increases. It becomes difficult.

  Of course, the main leg 4 also shows a square in this case, but is not limited thereto. Further, in addition to the structure of this columnar body, a well-known adjuster member having a structure in which an upper end of the plate-like seat has a male screw that supports the plate material 3 at its upper end is disposed around the back side of the plate material 3. It is also preferable to form. According to this configuration, the main leg 4 can be finely adjusted with respect to the unevenness of the slab surface of the floor foundation 1, and the workability can also be improved.

  In this case, as shown in FIG. 3, the auxiliary support portion 5 collectively includes the members provided on the plurality of floor panels 2 at the central portion of the reinforcing beam 51 formed of, for example, a sheet metal material. One electric cylinder 52 connected by a control device (not shown) to be controlled and an external electric wire is disposed and formed.

  In the electric cylinder 52, an impact absorbing portion 54 made of an elastic member such as a relatively hard rubber is provided at the tip of a shaft that is electrically moved in and out from the base 53. Therefore, according to the time zone or application, the surface strength of the entire double floor is controlled at once, and the unevenness of the walking feeling is eliminated by eliminating the unevenness of the floor foundation 1 at the center of the floor panel 2, and the board material. By virtue of the flexibility of No. 3 and the shock absorbing property of the shock absorbing portion 54, it is possible to ensure both of the shock absorbing property against a sudden shock and the walking ability when a person walks. Further, when the tip of the shaft is separated from the floor base 1, there is also an effect of preventing noise when an impact load is applied to the floor panel 2.

  A plurality of the electric cylinders 52 may be provided on one floor panel 2, and each of the plurality of electric cylinders 52 is brought into contact with or separated from the floor base 1 to change the bending state of the plate material 3 from the outside. It is possible to increase or decrease the strength of the surface of the floor panel 2 by fine adjustment.

  The cushion material 6 is a planar elastic body formed of, for example, a foamable polyurethane resin, and in this case, has two rectangular shapes. As shown in FIG. 2, the main leg portion 4 and the auxiliary support portion 5 Two things are disposed along the auxiliary support portion 5 in the space between the two. Accordingly, the provision of the cushion material 6 provides static or dynamic load support to prevent the plate material 3 from being bent and being damaged in an adjusted state where the auxiliary support portion 5 is not working. Play a role.

  In the double floor structure having the above-described configuration, the cushion material 6 is first disposed at a predetermined position on the floor base 1, and then a plurality of floor panels 2 are laid so as to cover the cushion material 6. A heavy bed is formed.

  In actual use, the above-described control device is used to collectively adjust and control the gaps between the plurality of auxiliary support portions 5 and the surface of the floor base 1 of the floor panel 2. Therefore, when the shaft of the electric cylinder 52 is extended, the surface of the entire double floor has sufficient strength. Thus, for example, in a hospital or the like, when a suddenly ill person comes out and a plurality of persons must run while pushing the moving bed, both the main leg 4 and the auxiliary support 5 are responsible for the load, and the floor surface The plate material 3 is not bent. On the other hand, when the axis of the auxiliary support portion 5 is not extended, the double floor has sufficient cushioning properties and necessary and sufficient surface strength.

  Further, in this case, when an impact is applied to the vicinity of the main leg 4, the impact force cannot be diffused. However, when an impact is applied to other places, the main leg 4 and the auxiliary support portion Since the planar cushion material 6 is interposed in the space between the floor panel 5 and the impact force is diffused and borne as an action of the cushion material 6, the floor panel 2 bends for a relatively short time and immediately returns to its original state. Return to the state. As a result, it has shock-absorbing performance to prevent injury such as broken bones even if the elderly people fall down over the entire surface of the plurality of floor panels 2, and the floor panel 2 bends with only the main leg 4 when the person walks. Therefore, safe walking is possible. Furthermore, when the floor panel 2 is excessively bent, it is supported by the cushion material 6 and can be prevented from being broken due to excessive bending of the plate material 3.

  As described above, according to the double floor structure of the present invention, when a high-strength floor surface is required by adjusting the gap between the auxiliary support portion 5 and the surface of the floor foundation 1, the auxiliary support is provided. If the length of the part 5 is increased to ensure the same strength as that of a normal flooring material and high strength is not required, the length of the auxiliary support part 5 is shortened to reduce the bending of the floor surface by the floor panel 2. It is possible to adjust and improve the shock absorption, and thus it is possible to provide a double floor structure in which the buffering property can be adjusted according to the use environment.

  It should be noted that the present invention is not limited to the above-described embodiments, and it is obvious that the embodiments can be appropriately changed within the scope of the technical idea of the present invention.
