Description

  The present invention relates to a floor panel used by being supported by a support member disposed on a structure, and also relates to a floor support structure using the floor panel.

  When installing electric wires and pipes under the floor, the floor is made into a double structure, and electric wires and pipes are installed between the upper and lower floors. There is a method of forming such a double structure floor using a particle board, but there is a method using a floor panel as another method.

In this method using a floor panel, a predetermined floor panel having a predetermined shape and a plurality of support members for supporting the floor panel are prepared, and the support member is placed on an original floor surface (such as a concrete slab). Further, a floor panel is placed on the support member to form a double floor. The floor panel has a square shape.
Such a technique is described in Patent Document 1 and the like.

Usually, the support members are arranged at four corners of the floor panel, and are arranged at other portions as necessary, so that they can be supported even when a load is applied to any position of the floor panel.
Moreover, since it is necessary to prevent relative movement between floor panels, a plurality of locking portions such as protrusions are provided on the support member, and adjacent floor panels are connected by the same support member.
JP 2001-303757 A

  Since the floor panel receives a load on the floor, the floor panel needs to have a predetermined strength. When a plate-like floor panel is used, the thicker one is stronger and more difficult to bend, but the floor panel becomes heavier. Therefore, strength is maintained and the weight is reduced by providing a grid-like beam protruding downward. And the protrusion of the above-mentioned support member is inserted in the space formed between the lattice beams.

  When adjusting the height of a floor panel provided with a lattice beam, a tool or the like may be inserted through a gap in the floor panel in an installed state. However, when the height cannot be adjusted from this gap, the vicinity of the edge of the floor panel may be perforated.

If the grid beam is at the edge of the floor panel, the grid beam may be scraped off during drilling and the strength may be reduced. The grid beams are also prevented from being damaged even when the edges of the grid are drilled.
However, since this collar is located outside the lattice beam, it is easily damaged by receiving an impact during transportation.

  Therefore, an object of the present invention is to provide a floor panel in which the lattice beam is not easily damaged when the vicinity of the end is drilled, and the collar portion is not easily damaged by an impact or the like.

  The invention according to claim 1 for achieving the above-mentioned object is supported by a support member arranged on the structure to form a floor support structure having a space with the structure. In a floor panel that can be formed, it has a flat plate portion and a lattice beam formed in a lattice shape on the lower side of the flat plate portion, and a flange portion located outside the lattice beam is near the edge of the flat plate portion. The floor panel is characterized in that the thickness of the collar portion is thicker than the thickness of the inner portion, which is the portion inside the collar portion of the flat plate portion.

  According to the first aspect of the present invention, the flat plate portion has a flat plate portion and a lattice beam formed in a lattice shape below the flat plate portion, and the outer edge of the flat plate portion is outside the lattice beam. Since the saddle is located at the edge of the floor panel, the lattice beam is not easily damaged when drilling near the edge of the floor panel, and the thickness of the saddle is the inner part of the flat part. Since it is thicker than the thickness, the heel portion is not easily damaged by impact or the like.

The invention according to claim 2 is characterized in that the thickness of the collar portion is 110% or more with respect to the thickness of the inner portion, and is 2 mm or more and 10 mm or less. It is a floor panel.
Here, when the thickness of the buttock or the inner part is not constant depending on the location, the thickness of the buttock or the inner part indicates the thickness of the thinnest part.

  According to the invention of claim 2, since the thickness of the collar portion is 110% or more with respect to the thickness of the inner portion and 2 mm or more and 10 mm or less, the collar portion is particularly affected by impact or the like. Hard to break.

  Moreover, in the floor panel which consists of a thermoplastic resin and a filler, the material to which the filler is added 20 vol% or more can be used (Claim 3).

  Furthermore, a support member can be arrange | positioned on a structure and a floor panel can be supported by a support member, and a floor support structure can be formed.

  And a supporting member has a projection part, and it can also support it, inserting the said projection part in the space formed by a lattice beam. In such a case, the floor panels can be connected by the protrusions.

  According to the floor panel of the present invention, the eaves portion is not easily damaged by impact or the like, and the lattice beam is not easily damaged even when the vicinity of the end is drilled.

Hereinafter, specific examples of the present invention will be described.

FIG. 8 is a perspective view of the support member. FIG. 9 is an exploded perspective view of the support member.

  As shown in FIGS. 1 and 2, the floor panel 10 according to the first embodiment of the present invention is provided with a flat plate portion 30 and lattice beams 31. The flat plate portion 30 is a square flat plate shape, and the lattice beam 31 is provided below the flat plate portion 30. When the floor panel 10 is used, the flat plate portion 30 is on the upper side and the lattice beam 31 is on the lower side. It is installed to become.

  As shown in FIG. 2, the lattice beams 31 are provided so as to extend in two directions so as to be orthogonal to each other, and a plurality of lattice beams 31 are provided. The direction in which the lattice beam 31 extends is the same as the square side of the flat plate portion 30, and the lattice beam 31 is provided on the entire flat plate portion 30.

  The outermost beam portion 31 a, which is the outermost portion of the lattice beam 31, is provided on four sides, has a square shape whose outer shape is slightly smaller than the flat plate portion 30, and is located near the side of the flat plate portion 30. Yes. And the collar part 33 is provided between the edge of the flat plate part 30, and the outermost beam part 31a. The flange 33 is provided on all four sides of the flat plate portion 30.

  The thickness of the flat plate portion 30 is different with the outermost beam portion 31a as a boundary. And as FIG. 3 shows, thickness T1 of the collar part 33 located in the outer side of the outermost beam part 31a is larger than thickness T2 of the inner side part 34 located in the inner side of the outermost beam part 31a. thick.

  The thickness T1 of the flange portion 33 of the present embodiment is substantially the same at any location, and is 6.5 mm. Moreover, the thickness T2 of the inner side part 34 is substantially the same in any position, and is 5.5 mm. Therefore, the thickness T1 of the flange portion 33 is larger than the thickness T2 of the inner portion 34, and the thickness T1 of the flange portion 33 with respect to the thickness T2 of the inner portion 34 is 118%, which is 110% or more.

When the value of the thickness T1 of the flange portion 33 is 2 mm or less, there is a possibility that the filling of the portion at the time of molding may be insufficient, and it is easily damaged by an impact or the like. When the value of the thickness T1 of the flange portion 33 is 10 mm or more, it takes a long time for cooling when molding the floor panel 10 continuously, and the molding cycle becomes longer, resulting in a decrease in production efficiency. The amount of the resin used in 10 is increased and the cost is increased, and it is difficult to perform the work when drilling the flange portion 33. Therefore, the thickness T1 of the flange portion 33 is desirably in the range of 2 mm or more and 10 mm or less.
In the floor panel 10 of the present embodiment, the collar portion 33 and the inner portion 34 have no difference in thickness depending on the position, but the thickness may differ depending on the location. In this case, the thinnest value is used as the value for calculating the ratio.

  Moreover, the width W of the collar part 33 is a distance between the flat plate part 30 and the outer side of the outermost beam part 31a, as FIG. 3 shows. The thickness T1 of the flange 33 with respect to the width W of the flange 33 is desirably 75% or more, and is not easily damaged by an impact.

  A reinforcing portion 35 is provided outside the outermost beam portion 31 a of the lattice beam 31. The reinforcement part 35 is provided so that the collar part 33 and the outermost beam part 31a may be connected. Moreover, the position of the reinforcement part 35 is provided corresponding to the position of the lattice beam 31 inside the outermost beam part 31a as shown in FIG.

The floor panel 10 is used in a state where the flat plate portion 30 is on the upper side and the lattice beam 31 is on the lower side, that is, in a state as shown in FIG. 1, and the lower side of the floor panel 10 (lattice beam 31 side). The support member 11 is disposed on the surface.
A space 32 formed between the lattice beams 31 is located below the floor panel 10 as shown in FIG. The shape of the space 32 is a prismatic shape, and the length in the vertical direction is longer than the length of the protruding portion 25 of the support member 11, and the protruding portion 25 can be inserted into the space 32.
Further, the position of the lowermost end of the lattice beam 31 is the same height.

  The shape of the space 32 formed by the lattice beam 31 is different between the square corner, the side, and the center, and spaces 32a, 32b, and 32c are formed, respectively.

In the space 32a near the corner, the inner widths of the lattice beams 31 in the two directions are approximately equal to the width L1 of the protrusion 25 of the support member 11, and only one protrusion 25 can be inserted.
In the space 32b near the side, the inner width of one of the lattice beams 31 is substantially equal to the width L1 of the protruding portion 25, and the other inner width is equal to the width L2 of the outer side of the protruding portion 25. Can be inserted.
In the center 32c, the inner width in the two directions of the lattice beam 31 is equal to the outer width L2 of the protrusion 25, and four protrusions 25 can be inserted.

Any kind of resin may be used for the floor panel 10, and a material obtained by recycling waste plastic once used can be used. Further, as the filler, for example, wood powder or coal ash called fly ash can be used, and a filler added with such a filler can be used. The floor panel 10 according to the present embodiment uses 60% thermoplastic resin waste plastic and 40% filler, and preferably 20% or more filler.
When the filler added to the floor panel 10 is less than 20%, the rigidity of the material becomes small. For this reason, it is necessary to increase the thickness of the flat plate portion 30 and the lattice beam 31 in order to reduce deformation during use of the floor panel 10. As a result, the production efficiency decreases, the amount of resin used for one floor panel 10 increases, and the cost increases.
