Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floor panel, a method for producing the same, and a floor structure using the same. More specifically, the present invention relates to a floor panel that is reduced in weight while ensuring desired strength and heat insulation, a manufacturing method thereof, and a floor structure using the floor panel.
[0002]
[Prior art]
Conventionally, as shown in FIG. 10, a large structure 102 is supported by a steel bundle 101 as a floor structure such as a detached house or a one-story floor assembly of an apartment house, and a joist 103 is formed on the back surface of the large structure 102. There is known a floor structure 100 in which floor board panels 104 arranged at a predetermined pitch are spread so that joists 103 are orthogonal to the large pull 102.
[0003]
In addition, in the illustrated example, the joist 103 is a so-called orthogonal structure in which the joist 103 is disposed orthogonal to the large pull 102, but a so-called parallel structure in which the joist is disposed in parallel with the large pull is also known. ing.
[0004]
Since the large pull 102 and joist 103 in this conventionally known floor structure 100 are made of wood, there are the following problems.
[0005]
(1) There is a problem caused by so-called thin trees. For example, there is a problem that floor noise is caused by thin wood.
[0006]
(2) Chemical treatment for ant protection and antiseptic measures is necessary. There is a high possibility that environmental pollution will occur in the course of this chemical treatment. Moreover, since the chemical treatment may impair the health of workers engaged in the treatment, it is necessary to take countermeasures.
[0007]
(3) Invite environmental degradation due to deforestation.
[0008]
In order to partially eliminate the problems of the conventional floor structure 100, proposals have been made and implemented for making the steel drawer 102 a steel steel drawer.
[0009]
For example, in Japanese Patent Application Laid-Open No. 8-4253, as shown in FIG. 11, a steel plate is formed by bending a steel plate so that the cross section has a substantially inverted trapezoidal shape and providing reinforcing ribs 111 on both sides. 110 has been proposed. Further, in Japanese Patent Laid-Open No. 2000-73527, as shown in FIG. 12, a steel pulling 120 in which a steel plate is bent so that the cross section has a substantially rectangular shape and reinforcing ribs 121 are provided on both side surfaces. Has been proposed.
[0010]
However, simply replacing the wooden fork 102 with the steel fork 110, 120 still has the wooden joists 103, so the problem with the floor structure 100 has only been partially eliminated, It is hard to say that it has been resolved.
[0011]
Therefore, although not yet publicly known, in order to solve all the problems of the conventional floor structure, a floor structure in which the joist as well as the joist is made of steel has already been proposed by the present inventor (Japanese Patent Application 2002-2002). 112002).
[0012]
However, in recent years, the social demands for resource saving and energy saving are increasing, and in the present situation where the energy saving standards for buildings, especially the standard values for heat insulation, are increasingly required, As in the case of the floor structure proposed earlier, when all of the large pulls, joists, and bundles are made of steel, the thermal conductivity of the metal is higher in each stage compared to wood, so whether the heat insulation method is used or not. It turned out to be somewhat unreasonable to meet these standards regardless of the region.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, although the present invention is explained based on an embodiment, referring to an accompanying drawing, the present invention is not limited only to this embodiment.
[0036]
FIG. 1 is a perspective view showing a main part of a floor structure in which a floor panel according to an embodiment of the present invention is used. The structure of the floor panel which concerns on FIG. 2 at the embodiment is shown with a three-plane figure. FIG. 3 shows the arrangement of the same floor panel on the large drawer.
[0037]
As shown in FIG. 1, the floor structure A is made of steel pulling (hereinafter simply referred to as pulling) at a predetermined pitch, for example, 910 mm pitch so as to be supported by a steel bundle 10 on soil concrete or a bundle foundation (not shown). 2 and a steel joist having a predetermined length along the longitudinal direction on the back surface (slightly shorter than the entire length of the floor plate 40 as will be described later), as shown in FIG. In the following, a heat insulating member is provided on a floor board 40 of a predetermined size (for example, abbreviated as a floor board) 40, for example, a particle board having a size of 910 mmW × 1820 mmL. 50 is combined to form a floor panel 60. As shown in FIGS. 2 and 3, the floor panel 60 is laid down so that the joists 30 are orthogonal to the large pull 20 It is shall.
[0038]
As shown in FIG. 3, the steel large fork 20 has a cross section of a square shape or a rectangular shape (in the illustrated example, a square shape of 75 mm × 75 mm). It consists of two materials, one material B1 and the second material B2 forming both side surfaces 22 and 23 and the lower surface 24, and the upper surface 21 side end portion and the side surfaces 22 and 23 upper end portions are joined symmetrically by caulking. Is. For this reason, the upper surface corner of the steel pullout 20 has a four-layer structure and a self-reinforcing portion is formed, which is obtained from an ordinary square pipe having the same plate thickness or a steel pullout formed by processing with one material. Strength rises markedly.
[0039]
That is, as shown in FIG. 3 (a), the end portion on the upper surface 21 side is bent inwardly to form a lateral U-shaped engaging portion 21a, while the upper end of the side surface 22 (23) is formed in the lateral U-shape. The engaging portion 22a (23a) is a horizontal U-shape opposite to the engaging portion 21a. After engaging the engaging portions 21a and 22a (21a and 23a), they are caulked and joined. Is. Further, as shown in FIG. 3A, the upper surface portion located behind the engaging portions 22a and 23a at the upper ends of the side surfaces 22 and 23 is formed as a U-shaped depressed portion 21b, The disengagement at the caulking portion 25 formed by the end portion on the upper surface 21 side is prevented. The reason why the caulking portion (self-reinforcing portion) 25 is on the upper surface 21 side will be described later.
[0040]
In addition, a plurality of ribs 21 c are formed over the entire length of the upper surface 21 of the large pull 20 so as to improve the bending rigidity, and the vertical length of the large pull 20 is formed on the side surfaces 22 and 23. One large rib 22c, 23c is provided to improve the compression rigidity. Similarly, the lower surface 24 is formed in a corrugated plate shape so as to improve the bending rigidity.
[0041]
Here, the first material B1 is a steel plate (plate thickness: 0.8 mm) that has been subjected to a rust prevention treatment. For example, a hot-dip zinc-5% aluminum-plated steel plate (plate thickness: 0.8 mm), a highly corrosion-resistant hot-dip zinc-6% aluminum-3% magnesium-plated steel plate (plate thickness: 0.8 mm), and the like. The second material B2 is a steel plate (plate thickness: 0.6 mm) that has been subjected to a rust prevention treatment. For example, hot-dip zinc-5% aluminum-plated steel plate (plate thickness: 0.6 mm), high corrosion-resistant hot-dip zinc-6% aluminum-3% magnesium-plated steel plate (plate thickness: 0.6 mm), and the like.
[0042]
As shown in FIG. 4, the steel joist 30 has a square or rectangular cross section (in the illustrated example, a 45 mm × 45 mm square shape), and is a first that forms the lower surface 31. It consists of two materials, the material B3 and the second material B4 that forms both side surfaces 32, 33 and the upper surface 34, and the lower surface 31 side end and the side surfaces 32, 33 lower end are joined symmetrically by caulking. Is. For this reason, the bottom corner portion of the steel joist 30 has a four-layer structure and a self-reinforcing portion is formed, and the strength is remarkably increased as compared with the steel joist formed by processing with one material.
[0043]
That is, as shown in FIG. 4 (a), the end portion on the lower surface 31 side is bent upward and inside to form a lateral U-shaped engaging portion 31a, while the lower end of the side surface 32 (33) is formed in the lateral U-shape. The engaging portion 32a (33a) is a horizontal U-shape opposite to the engaging portion 31a. After engaging the engaging portions 31a and 32a (31a and 33a), they are caulked and joined. Is. Further, as shown in FIG. 4A, the lower surface portion located behind the engaging portion 32a (33a) at the lower end of the side surface 32 (33) is formed as a U-shaped depressed portion 31b, and the side surface 32 (33). The disengagement at the caulking portion 35 formed by the lower end portion and the end portion on the lower surface 31 side is prevented from occurring. The reason why the caulking portion (self-reinforcing portion) 35 is on the lower surface 31 side will be described later.
[0044]
In addition, a plurality of ribs 31 c are formed over the entire length of the bottom surface 30 of the joist 30 so as to improve the bending rigidity, and the longitudinal compression rigidity of the joist 30 is provided on the side surfaces 32 and 33. Is provided with one large rib 32c, 33c at the center in the width direction, and corrugated portions 32d, 32e and 33d, 33e are formed on both sides thereof. The corrugated plate portions 32d and 32e and 33d and 33e formed on the side surfaces 32 and 33 also serve to reduce frictional noise with the heat insulating member 50. Further, the upper surface 34 is formed in a corrugated plate shape so as to improve the bending rigidity and promote the adhesion between the upper surface 34 and the back surface of the floor plate 40 by an adhesive.
[0045]
Here, the first material B3 is a steel plate (plate thickness: 0.6 mm) that has been rust-proofed. For example, hot-dip zinc-5% aluminum-plated steel plate (plate thickness: 0.6 mm), high corrosion-resistant hot-dip zinc-6% aluminum-3% magnesium-plated steel plate (plate thickness: 0.6 mm), and the like. The second material B4 is a steel plate (plate thickness: 0.4 mm) that has been subjected to a rust prevention treatment. For example, a hot-dip zinc-5% aluminum-plated steel plate (plate thickness: 0.4 mm), a highly corrosion-resistant hot-dip zinc-6% aluminum-3% magnesium-plated steel plate (plate thickness: 0.4 mm), etc. That is, the first material B3 is thicker than the second material B4.
[0046]
This is because the joist 30 has a structure in which a load is applied concentrating on the joint portion with the large pull 20, in the illustrated example, at both ends and the central portion, and therefore the lower surface 31 (first material) that is the surface facing the large pull 20. This is because it is necessary to increase the strength of B3). On the other hand, as will be described later, since the upper surface 34 is in full contact with the floor plate 40 to achieve load distribution, the plate thickness is reduced.
[0047]
That is, the joist 30 is composed of two materials (first material B3, second material B4), so that the thickness is necessary and sufficient to correspond to the function of each surface 31, 32, 33, 34. Therefore, it is possible to reduce the weight while ensuring sufficient floor rigidity. Thereby, compared with the case where a wooden joist is used, generally about 30% of weight reduction can be achieved and it becomes possible to improve an intensity | strength.
[0048]
As shown in FIG. 5, the heat insulating member 50 is a thick plate member having the same size as the floor plate 40, for example, a size of 910 mmW × 1820 mmL and a thickness slightly larger (for example, 55 mm) than the square size (45 mm) of the joist 30. Here, as the heat insulating member 50, it is possible to appropriately apply a foamed plastic heat insulating material such as a beaded polystyrene foam, an extruded polystyrene foam, a rigid urethane foam, a polyethylene foam, and a phenol foam. Forming the heat insulating member 50 from a composite with a resin (see, for example, JP-A-2001-261870) is desirable from the viewpoint of heat insulation and chemical resistance.
[0049]
Further, a joist housing groove 51 is provided on the upper surface of the heat insulating member 50, that is, the joint surface with the floor board 40, at the same pitch as the pitch of the joists 30 on the floor board 40.
[0050]
The joist storage groove 51 has a bottom 51a having a thickness of, for example, 10 mm and both longitudinal end portions having, for example, a thickness of 10 mm so as to store the joist 30 while covering all surfaces other than the joint surface of the joist 30 with the floor plate 40. 51b, 51b,...
[0051]
Further, on the lower surface of the heat insulating member 50 (the lower surface of the floor panel 60), an elongated plate is formed so that holes 53, 53,... Are provided so as to be orthogonal to the joist housing groove 51. The cutout portions 54, 54, ... for assembling the heat-insulating plywood (heat-insulating strength member) 52 are assembled. That is, the joist 30 is exposed to the bottom surface 31 through the holes 53, 53,... At both longitudinal end positions and the center position of the joist storage groove 51, and the heat insulating plywood 52 is used to bridge the exposed portion of each joist 30. It is joined to the lower surface 31 of 30.
[0052]
The heat insulating plywood (heat insulating strength member) 52 has a total length equal to the horizontal width of the heat insulating member 50, and the horizontal width is the same as the width of the upper surface 21 of the draw 20 (75 mmW × 910 mmL), or 1/2 (37.5 mmW × 910 mmL) It is composed of a plate member having a predetermined thickness and a predetermined strength, for example, a hard fiber board (hard board) having a thickness of 10 mm, a synthetic resin decorative plywood, or a particle board. It is assumed to be buffered and insulated.
[0053]
Further, the heat insulating plywood 52 is arranged so as to be orthogonal to the lower surface 31 of the joist 30, that is, so that the longitudinal direction coincides with the large pull 20 and is in full contact with the upper surface 21 (see FIG. 2). As a result, the load from the joist 30 is distributed and applied in the longitudinal direction of the large pull 20 through the heat insulating plywood 52, so that the load does not concentrate at the position facing the joist 30 in the large pull 20, and the plate thickness is thinner. Therefore, the required strength can be secured.
[0054]
Thus, the floor panel 60 is manufactured in the following procedure.
[0055]
(1) A steel joist 30 is attached to the back surface of the floor board 40 with an adhesive. In this case, as shown in FIGS. 2 and 3, the floor board 40 is bonded to the floor panel 60 while being shifted in the width direction so that the upper surface 34 of the joist 30 on one side appears half. This is preferable for improving the airtightness between the floor panels 60 and 60.
[0056]
(2) The joist 30 is fitted into the joist housing groove 51 of the heat insulating member 50, and the back surface of the floor board 40 and the upper surface of the heat insulating member 50 are joined by, for example, an adhesive.
[0057]
(3) The heat insulating plywood 52 is attached to the heat insulating plywood assembling notches 54, 54,... By, for example, an adhesive while being joined to the lower surface 31 of the joist 30 exposed through the holes 53, 53,.
[0058]
Hereinafter, the joining of the floor board 40 and the steel joist 30 in the above procedure (1) will be described in more detail.
[0059]
It is preferable that the joist 30 is disposed on the back surface of the floor board 40 so that the caulking portion (self-reinforcing portion) 35 of the joist 30 is located outward. This is because, when the floor board 40 is placed on the large pull 20, the caulking portion 35 functions as a reinforcing member, and the floor board 40 can have a desired bending rigidity while reducing the weight of the joists 30. It is. As described above, a steel joist in which a joint portion between the first material B3 and the second material B4 such as the caulking portion 35 functions as a reinforcing member is referred to as a “self-reinforced steel joist” in the present specification. .
[0060]
Next, with reference to FIG. 6 and FIG. 7, the mounting method to the steel bundle 10 of the steel pulling 20 is demonstrated.
[0061]
In FIG. 6, the mounting part F to the metal fitting 11 of the steel bundle 10 of the steel large drawing 20 is shown.
[0062]
As shown in FIG. 6, the large pull 20 is attached to the metal fitting 11 by making the large pull bottom 20 a into a groove shape of the steel bundle 10 through a cushioning material 12 made of a polyolefin-based single-sided adhesive tape or the like. It is made by screwing the fitted bottom portion 20a with a drill screw 13 protruding from the back surface of the bottom of the receiving bracket 11 in a state of being fitted to the receiving bracket 11.
[0063]
In this case, since the large drawing side 22 (23) is a thin plate from the viewpoint of weight reduction, when a load is applied to the large drawing 20, the lower part of the large drawing side 22 (23) tends to bulge outward. It is in. If this bulge becomes too large, there will be a problem in strength. Here, the plate thickness of the metal fitting 11 is considerably increased to a plate thickness of, for example, about 4.5 mm, and the length along the draw 20 is increased. By making the length L longer than the normal one in relation to the plate thickness, for example, the length is about 120 mm (the normal one is about 80 to 100 mm), and the side portion of the large bottom surface 24 is drilled. By screwing to the metal fitting 11 with the screw 13, the outward expansion of the large drawing side surface 22 (23) is suppressed. In other words, the bracket 11 is provided with a function as a reinforcing member for the large pull side 22 (23). Moreover, it is preferable from the point which suppresses the swelling of the large drawing side surface 22 (23) that the shape of the metal fitting 11 is made into a groove shape as shown in FIG. As a result, the thickness of the side surface 22 (23) is reduced, and the desired strength is ensured without imposing a large burden on the reinforcing ribs 22c, 23c of the side surface 22 (23). Incidentally, when the shape of the metal fitting 11 is a flat plate, the metal fitting 11 cannot exhibit a satisfactory function as a reinforcing member for the large pull 20.
[0064]
In addition, as shown in FIG. 6, it is preferable that the caulking portion (self-reinforcing portion) 25 of the large pulling 20 is mounted on the upper portion of the large pulling bottom portion 20a from the standpoint of strength. This is because the caulking portion 25 functions as a reinforcing member when the joist 30 is placed on the upper surface 21. In this specification, the steel pulling in which the joint portion between the first material B1 and the second material B2 such as the caulking portion 25 functions as a reinforcing member is referred to as “self-reinforcing steel pulling” in this specification. To.
[0065]
Next, with reference to FIG. 7, the mounting method to the floor board 40 of the steel joist 30 in the floor panel 60 and the mounting method to the steel large drawing 20 of the floor panel 60 are demonstrated.
[0066]
As shown in FIG. 7, the joist 30 is disposed on the back surface of the floor board 40 by bonding with an adhesive 41. This is because the joist 30 and the floor board 40 are integrated by bonding the joist upper surface 34 to the back surface of the floor board 40, and the floor board 40 can be made to have a desired bending rigidity while reducing the weight of the joist 30. It is.
[0067]
Further, as shown in FIG. 7, the floor panel 60 is fixed to the large pull 20 by placing the joist 30 perpendicularly to the large pull 20 and placing it on the large pull 20 via a heat insulating plywood 52, followed by The drill screw 44 is penetrated from the floor plate 40 to the large pulling upper surface 21 by using the stepped drill screw insertion hole 43 formed corresponding to the joining position with the pulling 20, and the floor plate 40 and the large pulling upper surface 21. And are joined by screwing. As a result, the joists 30 and the heat insulating plywood 52 are held by the floor board 40 and the large pull 20 in a pinched manner.
[0068]
In this case, the floor board 40 protruding from the side of the heat insulating member 50 of the floor panel 60 adjacent in the width direction uses an adhesive on the upper surface 31 of the joist 30 exposed from the floor board 40 of the floor panel 60 at one side edge. Then, the end surfaces of the adjacent floor panels 60, 60 are joined together. Thereby, the airtightness of the junction part of the floor panels 60 and 60 is ensured.
[0069]
Thus, the steel floor structure A of this embodiment supports the steel pulling 20 by the steel bundle 10 and combines the steel joist 30, the floor board 40, and the heat insulating member 50 to form the floor panel 60. The floor panel 60 is supported by the steel draw 20 so that the steel joist 30 is supported by the steel draw 20 through the heat insulating plywood 52.
[0070]
That is, since the joists 30 are made of steel instead of wooden, there is no factor causing dimensional errors such as warping, bending, and thinning of the joists 30, and it becomes possible to perform advanced dimensional management. For this reason, the floor panel 60 can be manufactured by a procedure in which the heat insulating member 50 is formed in advance in a predetermined size and shape, and the floor board 40 to which the joists 30 are joined at a predetermined pitch is assembled later. Manufacturing is extremely easy.
[0071]
In addition, since the floor base is formed simply by laying and fixing the floor panel 60 capable of highly dimensional management on the large pull 20 and fixing it, the construction becomes extremely easy.
[0072]
Furthermore, the steel pulling 20 and the steel joist 30 are in contact with each other through the heat-insulating plywood 52 having a high strength, and the joist 30 is covered with the heat insulating member 50 except for the joint surface with the floor plate 40. Therefore, it is possible to ensure load resistance while achieving sufficient buffering and heat insulation. Further, since the heat insulating plywood 52 is disposed along the longitudinal direction on the upper surface 21 of the large pull 20, the load applied to the large pull 20 through the joists 30 is dispersed in the longitudinal direction. 20 can be further reduced in thickness and weight.
[0073]
Furthermore, in the floor panel 60, the joists 30 are embedded in the heat insulating member 50, and all end surfaces are formed by the elastic heat insulating member 50, so that a high degree of heat insulation of the floor panel 60 itself can be achieved. At the same time, it becomes easy to ensure airtightness between the end surfaces of the floor panel 60. For this reason, it becomes easy to achieve a high degree of airtightness that meets recent energy saving standards.
[0074]
As mentioned above, although this invention has been demonstrated based on embodiment, this invention is not limited only to this embodiment, A various change is possible. For example, in the embodiment, the upper surface 21 of the large drawing 20 is disposed over the entire longitudinal range of the large drawing 20, but as shown in FIG. It can also be a large draw 20A. Similarly, as shown in FIG. 9, the lower surface 31 of the joist 30 may be a joist 30A that is dispersedly disposed only within a necessary range.
[0075]
Further, in the embodiment, the first material B1, B3 and the second material B2, B4 of the large pull 20 and the joist 30 are both made of the same material, but the first material B1, B3 and the second material B2, B4 are Different materials can be used. For example, the first materials B1 and B3 can be stainless steel plates, and the second materials B2 and B4 can be ordinary steel plates. And by further disperse | distributing and arrange | positioning 1st material B1, B3, further weight reduction is achieved, ensuring desired intensity | strength.
[0076]
In the embodiment, the reinforcing ribs are formed on each of the large drawing 20 and the joist 30. However, these reinforcing ribs may be provided as necessary, and thus are not necessarily provided.
[0077]
【The invention's effect】
As described in detail above, the floor panel of the present invention has an excellent effect that all the problems of the wooden floor panel are solved and a high degree of heat insulation is ensured. Moreover, since the floor panel of the present invention is reduced by about 30% in weight as compared with a wooden floor panel of the same size, there is also an excellent effect that the construction becomes easy.
[0078]
In addition, the floor panel manufacturing method of the present invention has an excellent effect that a floor panel can be manufactured in which all the problems of the wooden floor panel are solved and a high degree of heat insulation is ensured.
