Description

  The present invention relates to a composite board and a floor structure.

  Sound insulation and heat insulation are required for floor boards to be attached to floor bodies (concrete slabs, etc.) of apartment houses. As such a floor board material, for example, Patent Document 1 describes a composite board in which a board material is bonded to one side of a plastic plate having a large number of holes arranged in parallel.

Japanese Utility Model Publication No. 60-26831

  However, in the floor structure described in Patent Document 1, the compressive strength of the plastic plate (hollow plate) provided with a large number of holes is not sufficient, and when a large load is applied, the hollow plate may be deformed. In particular, when a tile or carpet is used as the plate material (finishing material), the load is more easily transmitted to the hollow plate than the flooring, so that the hollow plate is easily deformed.

  One of the objects according to some aspects of the present invention is to provide a composite board in which the hollow plate is not easily deformed. Another object of some aspects of the present invention is to provide a floor structure including the composite board.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following aspects or application examples.

[Application Example 1]
One aspect of the floor structure according to the present invention is
A hollow plate provided with a hollow portion;
A plastic plate provided on the hollow plate;
A finishing material provided on the plastic plate;
including.

  In such a composite board, even if a large load is applied from the finishing material side, since the plastic plate is provided between the hollow plate and the finishing material, the hollow plate is hardly deformed.

[Application Example 2]
In application example 1,
The compressive strength of the plastic plate may be greater than the compressive strength of the hollow plate and the compressive strength of the finishing material.

  In such a composite board, it is possible to more reliably prevent the hollow plate from being deformed by the plastic plate.

[Application Example 3]
In application example 1 or 2,
The finishing material may be a plastic tile.

  In such a composite board, even if a plastic tile having a low cushioning property is used as a finishing material, the hollow plate is hardly deformed with respect to the load by the plastic plate.

[Application Example 4]
In application example 1 or 2,
The finishing material may be a carpet.

  In such a composite board, even if a carpet having a low cushioning property is used as a finishing material, the hollow plate is hardly deformed with respect to the load by the plastic plate.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. Note that the embodiments described below do not unduly limit the contents of the present invention described in the claims. In addition, all the configurations described below are not necessarily essential configuration requirements of the present invention.

1. Composite Board First, the composite board according to the present embodiment will be described with reference to the drawings. FIG. 1 is a perspective view schematically showing a composite board 100 according to this embodiment. FIG. 2 is a cross-sectional view schematically showing the composite board 100 according to the present embodiment. FIG. 3 is a plan view schematically showing the composite board 100 according to the present embodiment. 2 is a cross-sectional view taken along the line II-II in FIG.

  As shown in FIGS. 1 to 3, the composite board 100 includes a base panel 40, a hollow plate 50, a plastic plate 60, and a finishing material 62. The composite board 100 is used as a floor that defines a room.

  The shape of the base panel 40 is, for example, a plate shape. The thickness of the base panel 40 is about 20 mm, for example. The size of the base panel 40 is, for example, about 30 cm long × 30 cm wide when viewed from the stacking direction of the hollow plate 50 and the plastic plate 60 (in plan view). The base panel 40 is, for example, a wooden plywood.

  The hollow plate 50 is provided on the base panel 40. In the illustrated example, the hollow plate 50 has the same shape and the same size as the base panel 40 in plan view. The thickness of the hollow plate 50 is, for example, 5 mm or more and 15 mm or less. The material of the hollow plate 50 is, for example, a plastic (synthetic resin) such as ABS (acrylonitrile butadiene styrene) resin or modified PPE (Polyphenylene ether) resin.

  The hollow plate 50 has a first side surface 51, a second side surface 52, a third side surface 53, and a fourth side surface 54. The side surfaces 51 and 52 are opposed to each other. The side surfaces 53 and 54 are connected to the side surfaces 51 and 52 and face each other. The side surfaces 51, 52, 53, 54 are surfaces that are not in contact with the base panel 40 and the plastic plate 60, for example.

  The hollow plate 50 is provided with a hollow portion 55. In the illustrated example, the hollow plate 50 has a shape in which a hollow portion 55 is provided in a plate-like member. The hollow portion 55 is a through-hole penetrating from the first side surface 51 to the second side surface 52, for example. In the illustrated example, a plurality of hollow portions 55 are provided, and the plurality of hollow portions 55 are arranged in parallel from the third side surface 53 to the fourth side surface 54. In the illustrated example, the shape of the opening provided in the first side surface 51 of the hollow portion 55 is a quadrangle, but is not particularly limited. Air exists in the hollow portion 55. The hollow plate 50 is formed by press molding, for example.

The plastic plate 60 is provided on the hollow plate 50. The shape of the base panel 40 is
For example, it is plate-shaped. The thickness of the plastic plate 60 is, for example, not less than 1 mm and not more than 10 mm. In the illustrated example, the plastic plate 60 has the same shape and the same size as the hollow plate 50 and the base panel 40 in plan view. In plan view, the hollow plate 50 is provided so as not to protrude from the plastic plate 60.

  The material of the plastic plate 60 is plastic such as ABS resin or modified PPE resin. The compressive strength of the plastic plate 60 (specifically, the compressive strength when a force is applied in the stacking direction of the hollow plate 50 and the plastic plate 60) is greater than the compressive strength of the hollow plate 50 and the compressive strength of the finishing material 62. large. The compressive strength can be measured by, for example, a known compressive strength measuring device.

  The finishing material 62 is provided on the plastic plate 60. The finishing material 62 is a member that is used for the interior and exterior of a building and is directly touchable. The shape of the finishing material 62 is, for example, a plate shape. The finishing material 62 is, for example, a P tile (plastic tile) or a carpet.

  In the illustrated example, the finishing material 62 has the same shape and the same size as the plastic plate 60, the hollow plate 50, and the base panel 40 in plan view. In the finishing material 62, the planar shape of the plastic plate 60, the hollow plate 50, and the base panel 40 is, for example, a square or a rectangle.

  In plan view, the finishing material 62 is longitudinal (in the illustrated example, along the one side 60a of the plastic plate 60) and laterally (in the illustrated example, the direction orthogonal to the one side 60a) with respect to the plastic plate 60. It is provided with a gap. For example, the vertical displacement amount α of the finishing material 62 with respect to the plastic plate 60 and the lateral displacement amount β of the finishing material 62 with respect to the plastic plate 60 are the same. The shift amounts α and β are, for example, 3 mm or more and 50 mm or less. As described above, the composite board 100 has the step 64 formed by the finishing material 62 and the plastic plate 60 because the finishing material 62 is provided so as to slide with respect to the plastic plate 60.

  Although not shown, a calp material made of a material obtained by adding an additive to synthetic resin may be provided between the base panel 40 and the hollow plate 50. In this case, the hollow plate 50 is provided on the base panel 40 via a calp material.

  The composite board 100 has the following features, for example.

  The composite board 100 includes a hollow plate 50 provided with a hollow portion 55, a plastic plate 60 provided on the hollow plate 50, and a finishing material 62 provided on the plastic plate 60. Therefore, even if a large load (load in the stacking direction of the hollow plate 50 and the plastic plate 60) is applied to the composite board 100 from the finishing material 62 side, the composite board 100 has a gap between the hollow plate 50 and the finishing material 62. Since the plastic plate 60 is provided, the hollow plate 50 is not easily deformed. Therefore, in the composite board 100, it can suppress that the hollow plate 50 is crushed with a load, and can have high sound insulation and heat insulation.

  Furthermore, since the composite board 100 includes the hollow plate 50 provided with the hollow portion 55, heat energy can be accumulated in the hollow portion 55. Therefore, in the composite board 100, even when the room defined by the composite board is warmed and the window of the room (the window provided on the wall material defining the room) is opened, the temperature of the room rapidly decreases. Absent. Therefore, in the composite board 100, it can have high heat retention property and can improve air-conditioning efficiency.

  Furthermore, since the composite board 100 includes the hollow plate 50 provided with the hollow portion 55, the cushioning property is high. Therefore, for example, when the composite board 100 is constructed as a floor of a hospital or a care facility, even if the patient transfers it, the influence on the patient is small.

  In the composite board 100, the compressive strength of the plastic plate 60 may be greater than the compressive strength of the hollow plate 50 and the compressive strength of the finishing material 62. Therefore, in the composite board 100, the plastic plate 60 can more reliably prevent the hollow plate 50 from being deformed.

  In the composite board 100, the finishing material 62 may be a plastic tile. In the composite board 100, even if a plastic tile having a low cushioning property is used as the finishing material 62, the hollow plate 50 is hardly deformed with respect to the load by the plastic plate 60.

  In the composite board 100, the finishing material 62 may be a carpet. In the composite board 100, even if a carpet having a low cushioning property is used as the finishing material 62, the hollow plate 50 is hardly deformed by the plastic plate 60 against the load.

  In the composite board 100, the hollow plate 50, the plastic plate 60, and the finishing material 62 have the same shape and the same size in plan view, and the hollow plate 50 is provided so as not to protrude from the plastic plate 60. The material 62 may be provided so as to be shifted in the vertical direction and the horizontal direction with respect to the plastic plate 60. Therefore, for example, as shown in FIG. 4, when a plurality of composite boards 100 are spread in the vertical direction and the horizontal direction to form a floor structure (in the case of construction), a step 64 due to the finishing material 62 and the plastic plate 60. As a result, the composite boards attached next to each other are not easily displaced and the joints are not easily disturbed. Therefore, construction becomes easy. In addition, in FIG. 4, it is a top view which shows the state which constructed the some composite board 100, the joint of the finishing material 62 is shown by the continuous line, and the joint of the plastic board 60 is shown by the broken line.

  Furthermore, after construction, the joints of the finishing material 62 and the joints of the plastic plate 60 do not overlap in plan view. Therefore, even when water spills on the finishing material 62, the water that has permeated from the joints of the finishing material 62 reaches the plastic plate 60, but hardly reaches the lower floor (such as a concrete slab) below the plastic plate 60. . Therefore, it can suppress that mold | fungi generate | occur | produce in a lower floor or a water leak arises in a lower floor.

  In the composite board 100, the material of the hollow plate 50 may be plastic. Therefore, in the composite board 100, for example, it is easier to process and is lighter than when the hollow plate 50 is made of wood. Furthermore, in the composite board 100, compared with the case where the material of the hollow plate 50 is a metal, for example, it has high heat insulation and is lightweight.

2. Next, a composite board 200 according to a modification of the present embodiment will be described with reference to the drawings. FIG. 5 is a cross-sectional view schematically showing the hollow plate 50 of the composite board 200 according to a modification of the present embodiment. FIG. 6 is a plan view schematically showing the hollow plate 50 of the composite board 200 according to the modification of the present embodiment. 5 is a cross-sectional view taken along line VV in FIG.

A hollow portion 59 is provided between the convex portion 58 a and the first plate-like portion 56. Air exists in the hollow portion 59. In the example shown in FIG. 5, the planar shape of the convex portion 58a is circular, and the plurality of convex portions 58a have a finely packed structure in plan view.

  In the composite board 200, the hollow portion 55 is a region between the first plate-like portion 56 and the second plate-like portion 57 and is a region other than the uneven portion 58 and the hollow portion 59. Therefore, the hollow portion 55 communicates with the entire hollow plate 50.

  The composite board 200 has the same effect as the composite board 100 described above.

  In the composite board 200, the hollow portion 55 communicates with the entire hollow plate 50. Therefore, in the composite board 200, heat energy can be stored over the entire hollow plate 50.

  In the composite board 200, a hollow portion 59 is provided between the convex portion 58 a of the concavo-convex portion 58 and the first plate-like portion 56. Therefore, in the composite board 200, heat energy can be accumulated even in the hollow portion 59.

  In the composite board 200, the planar shape of the convex portion 58a is circular, and the plurality of convex portions 58a have a close-packed structure in plan view. Therefore, in the composite board 200, for example, the compressive strength of the hollow portion 55 can be increased.
