Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated floor structure of a building, and more particularly, to a floor structure having excellent heat insulation which can be suitably used for a first floor of a wooden house.

[0002]

2. Description of the Related Art In wooden buildings for houses and the like,
For the purpose of preventing decay of a wooden part such as a base tied on a cloth foundation or a pillar joined to the base, it is required to provide a ventilation / ventilation space communicating with the outside air under the floor of the first floor. For this reason, even if it is hard to insulate the outer wall part, there is a disadvantage that the cooling and heating effect of the indoor living space is reduced due to the intrusion of the outside air from the floor and energy loss is caused.

[0003] Therefore, recently, examples of construction employing a heat insulating structure on the first floor have been rapidly increasing.

[0004] However, the conventional insulated floor structure of a wooden building still has many problems as described below.

[0005] The floor of a wooden building often has a traditional frame structure. That is, while binding the wooden base on the cloth foundation, a bundle of floors, large-scale, and joists make up a floor frame, and finish flooring directly on the joists or through the base panel made of plywood or wood fiber board. In many cases, construction is to be performed.

[0006] As such an insulated floor structure in a floor having a frame structure, there has been conventionally known, for example, Japanese Patent Publication No. 63-2514.
As described in Japanese Patent Publication No. 2
And it has been proposed to arrange a heat insulating material between adjacent drawers, or to dispose a heat insulating material between adjacent joists, as shown in Japanese Utility Model Application Laid-Open No. 64-24241. In practice, the latter structure has often been adopted.

However, in the above-mentioned conventional heat-insulating floor structure, since the heat-insulating material is missing in the large-scale or joist part, the heat-insulating material spread ratio to the floor area is about 80 to 90%. However, there was a problem that uneven heat insulation occurred.

[0008] In addition, it is not easy to install a heat insulating material in a tightly fitted state between a large drawer and a joist whose spacing is not always uniform, and a lot of time and labor are required for on-site construction work. Not only that, there is often a gap between the side edges of the insulation and the joists and the pulling, and also a gap between the insulation and the lower surface of the base panel or floor panel installed on it. And there are various problems that the heat insulating effect tends to be insufficient due to these gaps.

[0009]

SUMMARY OF THE INVENTION In view of the above problems, the present invention can be suitably applied to the floor of a wooden building, is easy to construct, and has excellent heat insulation performance.

[0027]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described.
This will be described more specifically with reference to the drawings.

In FIGS. 1 to 3, (G) is a solid foundation formed by pouring concrete, (H) is a cloth foundation that has risen around the solid foundation, and (K) is a wooden base tied on the cloth foundation (H). It is the foundation.

The heat-insulating floor structure according to the present invention is constructed on a solid foundation (G), and comprises a large number of support legs (1), a large number of joint construction materials (2), and a plurality of required joints. The main components are a heat insulating panel (3), a plurality of base panels (4), joint bars (5) and small pieces (6) for fitting.

The support leg (1) is a known one. That is,
A grounding seat (13) made of metal, synthetic resin, or elastic material is rotatably fitted and connected to the lower end of a metal or synthetic resin rod-shaped or hollow cylindrical support (11) having an externally threaded portion formed at the upper part. On the other hand, the female screw cylinder (14)
And a receiving plate (12) made of a wood material such as a particle board or a plywood is fixed to the upper end of the female screw cylinder (14). The receiving plate (12) is made of, for example, a 98 mm × 98 mm × 20 mm square plate-like small piece. A screwdriver is inserted through an adjustment hole (15) formed in the center of the receiving plate (12) to rotate the column (11). Thereby, the height position of the receiving plate (12) can be freely adjusted. After the height adjustment, the support (11) and the female screw cylinder (14) are poured by flowing an adhesive through the adjustment hole (15).
And the height can be fixed.

The support legs (1) are erected vertically and horizontally on a solid base (G) with a predetermined interval therebetween, and after positioning, the base (13) is a solid base. (G) is fixed by gluing, nailing, or a combination thereof. The arrangement pitch of the support legs (1) is set to, for example, 450 mm on the column (L) and 600 mm between adjacent columns (L) and (L).

The joint erection member (2) is the most important component in the present invention, and is adjacent to each other in each column (L) of the support legs (1).
(1) It is installed in a bridging state.

This joint part erection material (2) is made of a square rod-like joint insulation material (21) having a predetermined width, and a pre-joined joint rod (2) adhesively fixed to the upper surface of the upper surface in the width direction.
2).

The joint insulating material (21) has, for example, a width 1
It is made of a square rod having a thickness of 40 mm, a thickness of 55 mm, and a length of 400 mm. An upwardly facing stepped portion (21a) is formed on both side edges in the longitudinal direction by cutting or the like, whereby the width of the upper convex portion is reduced. The width is set to 98 mm similarly to the width of the receiving plate (12) in (1). An upwardly facing stepped portion (21b) is also formed at both ends in the longitudinal direction so as to protrude. The material of the joint heat insulating material (21) is the same as that of the heat insulating panel (3) described later.

The pre-joint joint rod (22) is interposed between joints between the longitudinal edges of the adjacent base panels (4) and (4) when the floor is being constructed. Therefore, it has a width corresponding to the joint gap, for example, a width of 20 mm, and has a thickness equal to the thickness of the base panel (4), for example, a thickness of 20 mm. This pointed joint bar (2
2) must be integrally fixed on the upper surface of the joint heat insulating material (21) in advance. In this fixed state, both ends protrude outward from the upper ends of the joint insulating material (21) by, for example, about 20 mm. (22a) shows this protrusion.

The joint construction material (2) having the above structure is
As shown in FIG. 6, the projections (22 a) of the front end joint bars (22) at both ends are engaged with the upper surface of the receiving plate (12),
And the stepped portions (21) at both ends of the joint insulating material (21).
b) is connected to the receiving plate (12) of the support leg (1) by engaging the lower surface of the receiving plate (12). That is,
The receiving plate (12) is connected to the receiving plate (12) in such a manner that the side edge of the receiving plate (12) is sandwiched between the projecting portion (22b) and the stepped portion (21b). By adopting such a connection structure, each support leg (1) adjacent in the column (L)
(1) At the time of attaching the joint portion erection material (2) to the space, the joint portion erection material (2) can be easily attached while preventing the undesired movement or dropping of the joint portion erection material (2), thereby improving workability. Can improve.

The heat insulating panel (3) is made of a hard foam synthetic resin plate such as closed-cell foamed polystyrene, hard foamed polyurethane, hard foamed polyethylene, or another hard heat-insulating material molded plate, for example, 1820 mm × 520 m.
It is formed in a rectangular plate shape of mx 55 mm. On the both side edges in the longitudinal direction, oppositely facing, that is, downward facing chipped steps (3a) corresponding to the chipped steps (21a) of the joint insulating material (21) are formed by cutting. It has been made.

The heat insulating panel (3) is fitted into the column (L) (L) adjacent to the row of the support legs (1) to which the joint part erection material (2) is attached in advance in a state of being dropped from above,
The stepped portions (3a) facing downward on both sides are joined to the joint insulating material (2).
1) It is supported and attached to the upwardly facing stepped portion (21a) by engaging it with the stepped portion (21a). Employing such a support structure of the heat insulating panel (3) can prevent a gap from being generated between the side edge of the heat insulating panel (3) and the side edge of the joint insulating material (21). Support the points that can be made, and both side edges of the heat insulating panel (3) from below over almost the entire length,
This is advantageous in that the heat insulating panel (3) can be firmly supported without fear of falling off or warping.

Between the column (L) of the first support leg (1) and the base (K), and the column (L) of the last support leg (1).
Of the thermal insulation panel (3) arranged between the base and the base (K),
The side edge on the base (K) side may be supported by an appropriate support means attached to the base (K) side.
The structure of the support means is not particularly limited. In one preferred example shown in FIG. 1, a joist (K1) is attached to the inner side surface of the base (K), and a plurality of L-shaped support brackets (K) are provided at predetermined intervals on the joist (K1). 7) is attached, and the lower surface of the side edge portion of the heat insulating panel (3) is supported and supported on the support metal (7).

In the embodiment shown in FIGS. 1 to 6, when all the heat insulating panels (3) are provided, the floor area of the support legs (1) is reduced except for a part of the lower surface of the receiving plate (12). Is entirely covered with the heat insulating panel (3) and the joint heat insulating material (21), and the upper surfaces thereof are formed to be almost flat.

Incidentally, the stepped portion (3) of the heat insulating panel (3)
a) and the stepped portion (21) of the joint insulating material (21).
a) (21b) is formed not only by cutting as described above, but also by bonding at least two heat-insulating plate materials having different dimensions, such as the above-mentioned foamed synthetic resin plates, to the heat-insulating plate material on the lower surface side. It may be formed by a protruding peripheral portion. In this case, the two or more heat insulating plate members may be the same material or different types of materials.

In the illustrated embodiment, both longitudinal edges of the heat insulating panel (3), that is, the shorter edges are formed as vertical surfaces having no steps. Alternatively, the adjacent heat insulating panels (3) and (3) may be connected to each other without any gap even on the edge side by forming a stepped portion that is engaged with each other between the adjacent panels.

The rigid base panel (4) constitutes a base surface for laying a finishing floor material (not shown), and is made of a particle board or a plywood in order of strength and cost. However, an oriented strand board (OSB), a medium density fiber board (MDF), a hard fiber board (HB), or the like may be used. In this embodiment, the dimension of the base panel (4) is 600 mm × a general standard dimension.
A rectangular shape of 1820 mm × 20 mm is used.

The rigid base panels (4) are sequentially laid and arranged in tandem on the flat upper surfaces of the heat insulating panel (3) and the joint heat insulating material (21) with the pre-joined joint bars (22) interposed therebetween. You. At this time, the base panels (4) (4) arranged in each column are, for example, 2
The jointing bar (5) is inserted into the joint gap at the same time as the base panel is laid or after the base panel (4) is arranged. Be placed. Also, the base panels (4) are arranged in a staggered arrangement as shown in FIG. 3 so that joint lines in the width direction do not line up in a straight line between adjacent panel rows. Furthermore, each base panel (4)
Are laid in such an arrangement that the corners of the four corners are carried on the receiving plate (12) of the predetermined support leg (1). As a result, the base panel (4) is supported on one side edge of the receiving plate (12) of the one or more support legs (1) at the intermediate portions of the both side edges. Then, the corner portion and the side edge portion are firmly joined and fixed to the support plate (12) with a fixing tool such as a screw or a nail.

Although the rigid base panel (4) has a rectangular shape in the illustrated example, it may have a square shape. Further, the arrangement may be a base shape or a staggered shape.

When the base panel (4) has been laid and the joint bars (5) for fitting have been provided, the receiving plate (12)
Only the central portion of the upper surface is left exposed.
Then, the height adjustment operation of each support leg (1) described above is performed through the remaining exposed portion to adjust all the base panel (4) surfaces to be completely horizontal flat surfaces, and then through the holes (15). The height of the support leg (1) is fixed by means such as pouring an adhesive. Finally, a joint rod small piece (6) formed in a corresponding shape in advance is fitted and arranged in the space of the remaining exposed portion on the receiving plate (12), and all the space between the base panels (4) and (4) is placed. It is said that the joint gap was closed.

By the way, the above-mentioned jointing rod for fitting (5),
Both the pre-joint bar (22) and the small joint bar piece (6) have the same configuration. That is, a square rod-like body made of plywood or other hard wood material is used as a core material (10).
On both sides, a band-shaped cushioning material (20) made of an elastic material such as rubber or soft foamed synthetic resin is laminated and integrated in a laminated manner. The elastic cushioning material (20) is disposed in a state where both side surfaces thereof are elastically abutted against the peripheral side surface of the base panel (4), so that the expansion and contraction of the base panel (4) due to a change in temperature and humidity can be performed. Absorbed by the cushioning material (20) so as not to form a gap between the base panel (4) and the base panel (4).
(4) can prevent the occurrence of a mountain-shaped bulging deformation at the joint portion.

The above-described insulated floor structure is completed by laying a flooring material for finishing (not shown), a carpet, a tatami mat or the like on the laying surface of the base panels (4) and (4). Needless to say, there is.

In the above-described insulated floor structure shown in the embodiment of FIGS. 1 to 6, only one part of the lower surface of the receiving plate (12) of the support leg (1) is shown in FIG. Thus, a portion where the heat insulating material does not exist, that is, a missing portion (9) of the heat insulating material occurs. In order to avoid a reduction in the heat insulating effect due to the missing portion (9), as shown in FIG. 7, a joint insulating material (21) adjacent to the lower surface of the receiving plate (12) via the receiving plate is provided.
(21) A rectangular heat insulating material block (3
It is recommended that 1) be added in advance.

Alternatively, the heat insulating material block (3)
Instead of attaching 1), as shown in FIG. 9, both ends of the joint insulating material (21) are extended, and the notch recess (33) into which the female screw tube (14) of the support leg (1) is fitted at the tip. May be formed so that joint heat insulating materials (21) (21) of adjacent joint part erection materials (2) (2) are arranged in abutting manner.

In the above-described embodiment shown in FIGS. 1 to 6, the both sides of the heat insulating panel (3) are supported by the joint heat insulating material (21). As shown in the figure, a rectangular support plate (35) is provided on the lower surface of the receiving plate (12) of the support leg (1) via a rectangular heat insulating material block (32) so as to protrude outward. The side edge of the heat insulating panel (3) may be supported on the protruding portion.

Further, as shown in FIG. 10, a support plate (36) projecting sideways is attached to the lower surface of the joint insulating material (21) by bonding or the like. The side edge of the heat insulating panel (3) may be put on the edge and supported. The support plate (36) is shown in FIG.
As shown in FIG. 11, a support plate (36a) composed of a plurality of plate pieces may be used and attached at predetermined intervals as shown in FIG. The means for attaching the support plates (36) (36a) may be any means other than bonding, such as fixing with nails such as nails, screws, screw nails, and staples, or fixing with a combination of bonding and nails. Can be adopted.

By the way, in the above embodiment, the case where the joint erection material (2) is arranged only in the column (L) direction of the support leg (1) to assemble the heat insulating floor has been described. ) May be similarly provided between the support legs (1) and (1) adjacent to each other in a row in a direction perpendicular to the joint direction. In addition, the joint portion bridging material (2) is also provided between the adjacent support legs (1) and (1) in both the column (L) direction of the support legs (1) and the row direction perpendicular to the column (L) direction. May be erected and arranged. In this case, the heat insulating panel (3) is arranged so that all of the four peripheral side surfaces are surrounded by the joint heat insulating material (21) of the joint erection material (2). In addition, the joint bar (5) for fitting is
Since it is made to be pre-attached integrally to the joint heat insulating material in the same manner as the joint joint erection material (2) shown in the figure, the adjacent heat insulating panel is automatically installed at the stage of laying the heat insulating panel (3). (3) It is disposed so as to be sandwiched between both short edges of the (3). Therefore, especially in the present invention, the "joining joint bar (5)" according to claim 1 is
As described above, the case where the joint portion erection material (2) is preliminarily joined and integrated with the joint heat insulating material is also included.

As described above, the base panel (4) uses a rigid wood board such as a particle board or a plywood. However, the base panel (4) itself may absorb moisture from both the upper and lower surfaces or the surrounding wood edge. For this reason, for example, when the floor foundation (G) such as a solid foundation made of concrete or mortar is not sufficiently cured and dried, the floor foundation is applied, or when the floor foundation (G) is constructed in an undried state after rainfall. In this case, the base panel (4) expands mainly due to moisture absorption from the lower surface side, or also from the upper surface side or the surrounding wood edge, and thus to the joint portion of the floor finishing materials installed thereon. There is a possibility that a gap is generated. Further, when drying after moisture absorption, the base panel (4) shrinks conversely, and as a result, there is a possibility that a swelling deformation due to a push-up phenomenon occurs at a joint portion of the floor finishing materials constructed on the upper surface side. . If the upper surface becomes wet due to rainfall after the construction of the base panel (4), the above concern is further increased.

In order to cope with such a problem, in a preferred embodiment of the present invention, as shown in FIG. 12, the moisture-proof layers (40) and (40) are formed on the upper and lower surfaces of the base panel (4).
Is provided. The moisture-proof layer (40) may have any configuration as long as it can block moisture and moisture. In the preferred embodiment shown in FIG. 12, a barrier sheet (41) composed of a synthetic resin film or sheet such as polyethylene, polypropylene, vinyl chloride or the like, or a metal thin film sheet such as an aluminum foil or the same vapor-deposited layer is mainly used. A three-layer sheet having a total thickness of about 65 to 200 μm, in which fiber sheets (42) and (43) made of paper, nonwoven fabric, or woven fabric are laminated and integrated in a sandwich shape, is used. The lamination and integration are performed by an adhesive, heat fusion, or vapor deposition. The fiber sheets (42) and (43) are useful for ensuring good adhesion of the moisture-proof layer (40) to a counterpart member. Therefore, it is desirable to provide on both sides of the barrier layer (41), but it is also possible to provide it on only one side of the barrier layer (41). In this case, the attachment of the moisture-proof layer (40) to the surface of the base panel (4) can be performed by heat-sealing a barrier sheet (41) made of a thermoplastic synthetic resin film or sheet.

As shown in FIG. 12, the base panel (4) is also provided with a kiguchi moisture-proof layer (45) on the four circumferential side surfaces, that is, on the kiguchi surface. This Kiguchi moisture barrier (45)
Is formed by applying a water-repellent agent or a synthetic resin waterproof paint, or attaching a moisture-proof tape. here,
As the water repellent, molten paraffin, synthetic resin to which a wax such as paraffin is added, or the like is used. Also,
As the synthetic resin waterproof coating, those made of various resins such as tar-based, acrylic-based, urethane-based, acryl-styrene-based, acryl-vinyl acetate-based, rubber-based, and fluorine-based paints are used.

As a means for applying the water repellent or the synthetic resin paint to the lip of the mouth, there are employed a brush coating, a spray, a mechanical coating method using a roll coater or the like, and a method of dipping the lip of the lip.

In addition, when using a moisture-proof tape, the tape may be a paper adhesive tape or cloth tape having an outer surface subjected to a water-repellent treatment, an adhesive tape made of a synthetic resin such as polypropylene, an adhesive tape made of a thin metal material such as aluminum, An aluminum vapor-deposited paper adhesive tape or the like is used. These moisture-proof tapes may be affixed beforehand to the edge of the base panel (4) before construction, or may be affixed at the time of construction.

The adhesive used for attaching the moisture-proof layer (40) to the base panel (4) includes urea-based, urea-melamine-based, vinyl acetate-based, ethylene vinyl acetate-based, urea vinyl acetate-based, and phenol-based adhesives. Various known adhesives such as vinyl chloride, urethane and the like can be arbitrarily selected and used.

Also, the receiving plate (12) of the support leg (1) made of a woody material such as particle board, plywood, etc.
A moisture-proof layer similar to the base panel may be provided. Thereby, the influence based on moisture absorption and drying of the receiving plate (12) can be prevented.

In addition, various design changes are allowed in specific embodiments of the present invention without departing from the structure of each invention described in the claims.

The present invention is not limited to a wooden building,
