Description

The present invention belongs to the technical field of floor panels used in constructing wooden buildings.

There is a frame wall construction method (2×4 construction method) as one of construction methods for wooden buildings. This framed wall construction method mainly uses a frame made of standard lumber with a cross-sectional dimension of 2 x 4 inches, and is manufactured by nailing structural plywood to a frame. It is used to construct a building by connecting with (belts and anchor bolts), the construction period is short, and the workability is good, so the demand for it is increasing in recent years.
By the way, the floor panel of the framed wall construction method has conventionally been manufactured by forming a floor assembly with a framework and joists, and pasting plywood on it. Its height was about 235 mm, since 2×10 inch members are generally used for floor panel materials.
By the way, regardless of whether the flooring material including the floor panel is a frame wall construction method or a wooden frame construction method (conventional construction method), in order to improve workability, fire resistance, heat insulation, or sound insulation (airtightness), By devising the structure, flooring materials of various forms as described below have been developed.

For example, Patent Document 1 describes the construction of a house or the like that can be constructed easily and at a low cost by using a panel of a composite structure in which rectangular lumber is sandwiched between lumber core plywood (see FIG. 5) with excellent heat insulation properties. An article and method of construction thereof are disclosed.
In Patent Document 2, by using a panel in which a foamed synthetic resin heat insulating material is sandwiched between plywoods, it is possible to maintain an appropriate heat insulating effect for a long period of time, have excellent fire resistance, and increase the thickness of the plywood. discloses a structural multifunctional panel that eliminates the need for columns and beams and is suitable as a constituent material for walls, floors, roofs, and the like.

In the building and its construction method according to Patent Document 1, it was necessary to increase the thickness of the plywood in order to secure the in-plane rigidity and to increase the isolation material (joist) to secure the out-of-plane rigidity. . In addition, since it is composed only of wood, it is equipped with board-based fire-resistant materials and sound-insulating materials to ensure fire resistance and sound insulation. There were problems such as
In the structural multifunctional panel according to Patent Document 2, similarly to Patent Document 1, it is necessary to increase the thickness of the plywood in order to ensure in-plane rigidity. There were problems such as narrowing the space.
Although the construction method according to Patent Document 3 can ensure fire resistance and sound insulation, since the concrete slab is formed on top of the beams or joists, the floor and ceiling are raised, which causes problems such as a narrower living space. there were. In addition, there was also the problem that the construction period would be prolonged due to the work of placing concrete on site.
Although the precast synthetic slab according to Patent Document 4 can also ensure fire resistance and sound insulation, since the concrete slab is formed on top of the beam or joist, the floor and ceiling are high, which causes problems such as narrowing the living space. there were. Since the structural members do not include wooden parts in the first place, there is also the problem that it is difficult to connect with the wooden wall panels on the upper and lower floors when applying it to a wooden building.

In summary, conventional flooring materials developed for the purpose of improving workability, fire resistance, heat insulation, or sound insulation (airtightness) all have advantages and disadvantages.
Specifically, for example, in the frame wall construction method, if the panel thickness of the floor panel can be formed thinner than the general panel thickness of 235 mm while maintaining the strength and rigidity, it will be possible to form a wider living space. Although it is clear that a flexible and rational structural design can be realized and is very beneficial, the techniques according to Patent Documents 1 to 4 cannot contribute to the suppression of panel thickness, and there is room for improvement. .

The present invention has been devised in view of the above-mentioned problems of the background art, and its object is to efficiently improve the strength and rigidity of a structure, and to provide a lightweight and excellent handleability. To provide a floor panel for a wooden building capable of efficiently suppressing the height dimension of the floor panel by incorporating the deck plate into the wooden floor panel.

[Effect of the invention]

According to the wooden building floor panel of the present invention, the following effects can be obtained.
The floor panels of the first to fifth inventions can be installed by dropping the deck plate below the upper surface of the wooden frame by the support member, so the thickness of the floor panel can be reduced compared to installing on the conventional beams. The thickness can be reduced (to about 60%).
Moreover, since a plurality of receiving members each having a compact size are scattered to support the deck plate, a wall panel can be provided on the upper surface of the wood.
Furthermore, the long base member extending in the axial direction of the wood on the upper surface of the lower flange portion of the receiving member allows the deck plate to be installed regardless of the mounting position of the receiving member, enabling flexible structural design. Become.
In particular, the floor panel of the sixth aspect of the invention can increase the supporting strength against deck plates and cast concrete.
In the floor panels of the first to fifth inventions, since the single deck plate has high rigidity, joists can be omitted, and in-plane rigidity can be maintained even if plywood thinner than conventional plywood is attached. In addition, since it has sufficient rigidity, it can be used properly according to the structural design, either dry (deck plate alone) or wet (concrete placing).
In the floor panels of the first to fifth inventions, the wooden frame that constitutes the outer periphery of the floor panel is the same as the wooden frame of the floor panel used in the conventional framed wall construction method, so it can be used with the wall panels on the upper and lower floors. It can be constructed in the same way as the conventional frame wall construction method in connection.
In the floor panels of the 1st to 5th inventions, the deck plate is dropped below the upper surface of the wooden frame. Mold work can be omitted.
In particular, in the floor panel of the second invention, since the notch recess is formed on the upper surface of the wooden material, even if the receiving member is attached to the wooden material, unevenness will not occur, and the floor material or wall material to be attached later will not be uneven. A good fit can be achieved. In addition, since the receiving member and the upper end level of the wood are flush with each other, the wall panel on the upper floor can be installed without gaps.
In particular, in the floor panel of the third invention, a slit is formed in the side surface of the wood and the upper flange portion of the receiving member is inserted. It is possible to realize a highly sound floor panel that is structurally very stable without the risk of coming off.
In particular, in the floor panel of the fourth invention, since the notch recess is formed on the side surface of the wood, the gap between the wood and the deck plate (the thickness of the receiving member) is filled (can be filled) and concrete can be placed. It is possible to prevent leakage of time concrete and sound leakage from the upper floor.
In particular , in the floor panel of the fifth aspect of the invention, since the concrete placed on the upper surface of the deck plate is integrated with the framework, concrete leakage can be prevented.

Next, an embodiment of a wooden building floor panel according to the present invention will be described with reference to the drawings.
Of the "Examples 1 to 3" described below, the original examples of the present invention are "Example 2" and "Example 3", and "Example 1" is a reference example related to the present invention. However, for the sake of convenience, all of them will be referred to as examples in the following description.
[Example 1]

As shown in FIGS. 1 to 3, the floor panel of a wooden building according to the present invention is formed by bending peaks 21 and valleys 22 alternately through slopes 23 to form a substantially trapezoidal waveform cross section. A wooden building floor panel comprising a deck plate 2 , a wooden frame (wooden frame) 3 framed in a rectangular shape , and a receiving member used to arrange the deck plate in the plane of the wood , The receiving member 1 includes an upper flange portion 11 that rests on the upper surface of the wooden piece 3 or is inserted into the side surface, a web portion 12 that hangs down along the side surface of the wooden piece 1, and a valley portion 22 at the end of the deck plate 2. It is formed in a substantially Z-shaped cross section together with the supporting lower flange portion 13, and is a structure in which the deck plate 2 is supported by being provided on the wood 3 on at least two opposite sides of the four sides of the framework.

The wood 3 is assumed to be the wood 3 used in the frame wall construction method in this embodiment. As an example of the wood according to the illustrated example, two pieces of 2×6 material (with a thickness of about 140 mm) are used, and the in-plane dimensions are formed to, for example, about 2500×2500 mm.
As shown in FIG. 3, the wooden piece 3 according to the present embodiment has cutout recesses 3a and 3b on its upper and side surfaces for positioning the upper flange portion 11 and the web portion 12 of the receiving member 1. A notch concave portion having a substantially inverted L-shaped cross section is formed by connecting the .
The notch recesses 3a and 3b are formed by notching the same size as the upper flange portion 11 and the web portion 12 formed in a flat plate shape. In other words, it is formed so as to be flush with the outer peripheral surface (upper surface and side surface) of the lumber 3 in a state in which the upper flange portion 11 and the web portion 12 are received.

The deck plate 2 is formed of a steel plate having a substantially trapezoidal corrugated cross section in which crests 21 and troughs 22 are alternately connected via sloping portions 23 . A deck plate referred to as composite slab deck plate 2 with sections is employed.
The dimensions of the deck plate 2 are, for example, about 600 mm in width (two-ridge type), about 50 mm in height (height), and about 115 to 125 mm in width at the top (flat portion) of the peaks and valleys. The plate thickness is about 1.0 to 1.6 mm, and the total length (span length) is about 1.8 to 3.6 m. FIG. 1 shows a state in which four deck plates 2 are connected in the width direction.
Of course, the form (shape and dimensions) of the deck plate 2 is not limited to this, and the design can be appropriately changed according to the structural design such as the installation area, the installation interval of the support beams, and the strength required for the structure.
For example, depending on the in-plane dimension of the wood (wooden frame) 3, it is appropriate to use a deck plate 2 for adjusting the width of a single mountain type having a width of about 300 mm. In addition, if concrete is not placed (dry type), a normal deck plate without the key grooves and steps can be used.
By the way, the deck plate 2 has a through hole 22a (see FIG. 4) formed at the joint portion of the bottom flange 13 of the receiving member 1 at the bottom portion 22 of the deck plate 2. As shown in FIG.

The receiving member 1 is made of metal (made of steel), and is formed with the upper flange portion 11, the web portion 12, and the lower flange portion 13 to have a substantially Z-shaped cross section.
The upper flange portion 11 is formed with through holes 11a for inserting fasteners 6 such as screws 6, bolts, and drift pins used for attachment to the wood 3. As shown in FIG. Six through-holes 11a according to the illustrated example are formed in a well-balanced manner, but the design can be appropriately changed according to the structural design. Further, the screw 6 fixes the upper flange portion 11 and the wooden piece 3. For example, if the web portion 12 is fixed by forming a through hole, the receiving member 1 and the wooden piece 3 may be displaced from each other. The fixing tool is not limited to the screw 6, and it may be fixed in any manner regardless of the fixing position.
The lower flange portion 13 is formed with a through hole 13a through which a fastener 7 such as a bolt 7 used for attaching to the deck plate 2 is inserted. Although two through-holes 13a according to the illustrated example are formed on the left and right in a well-balanced manner, the design can be appropriately changed according to the structural design. However, when the lower flange portion 13 and the deck plate 2 are integrated by welding means, the through hole 13a is unnecessary.
The dimensions of the receiving member 1 are, for example, when viewed in the cross-sectional direction (see FIG. 3), the width of the upper flange portion 11 is about 57 mm, the height (total height) of the web portion 12 is about 127 mm, and the lower flange portion 13 is about 127 mm. has a width of about 64 mm, a plate thickness of about 6 mm, and a depth (width) B (see FIG. 2) of about 110 mm.

Of course, the form (shape and dimensions) of the receiving member 1 is not limited to this, and the design may be appropriately changed according to the structural design considering the form of the deck plate 2, the wooden piece 3, and the like.
For example, depending on the structural design, as shown in FIG. 5, the upper surface level of the deck plate 2 is made substantially the same as the upper surface level of the wood 3 by using the receiving member 1 with the web portion 12 having a shorter height dimension. Alignment is also possible.
Alternatively, the receiving member 1 may be formed by combining two angle members (for example, by welding their back surfaces together) to form a substantially Z-shaped cross section.

Next, a method (assembling procedure) for realizing a floor panel for a wooden building composed of the wooden timber 3, the deck plate 2, and the receiving member 1 having the above-described configuration will be described. It should be noted that the method described below is merely an example.
First, as shown in FIG. 6, a piece of wood (a wooden frame) 3 framed in a rectangular shape of a predetermined size is prepared. The notch recesses 3a and 3b are formed in advance on (two opposing sides of) the wood 3 at the portions where the receiving member 1 is hooked. That is, in this embodiment, since a total of 18 receiving members 1 are hooked, the wood (wooden frame) 3 is formed with a total of 18 notch recesses 3a and 3b.
Next, a plurality of (18 in the illustrated example) receiving members 1 are attached to the notch recesses 3a and 3b of the wood 3, respectively, and the upper flange portion 11 thereof is placed on the upper surface of the wood 3 (the notch recesses 3a of the wood 3). ), and the web portion 12 is brought into contact with the side surface of the wooden piece 3 (notched concave portion 3b), thereby positioning the receiving member 1 on the wooden piece 3. As shown in FIG. Thereafter, screws 6 are passed through the through holes 11 a of the upper flange portion 11 to fix the receiving member 1 to the wood 3 .

Next, the deck plate 2 is lifted to a predetermined height, dropped between the receiving members 1, 1, positioned, and erected.
Specifically, in order to lay the deck plate 2 without gaps in the plane surrounded by the wood 3 , the grooves 22 at both ends in the longitudinal direction of the deck plate 2 are attached to the corresponding lower flanges of the receiving member 1 . The receiving member 1 is placed on the upper surface of the portion 13, the cores of the through hole 22a of the valley portion 22 and the through hole 13a of the lower flange portion 13 are aligned, and bolts 7 are passed through and fastened with nuts 8. , and the deck plate 2 is supported by the wood 3 via the receiving member 1 to realize a floor panel (see FIG. 1).
Then, for example, as shown in FIG. 4, the wood (wooden frame) 3 of the floor panel according to the present invention is installed on the upper surface of the wall panel 30 on the lower floor, and the wall panel 20 on the upper floor is installed thereon. Etc., the same construction as the conventional frame wall construction method is performed.

As shown in FIG. 7, the floor panel is a floor panel made by placing concrete 5 on the upper surface of the deck plate 2 to form a precast synthetic slab before being incorporated into the upper and lower wall panels 20 and 30. Alternatively, a floor slab structure may be employed in which concrete 5 is cast after being incorporated into the upper and lower wall panels 20 and 30 .

According to the wooden building floor panel having the above configuration, the following effects can be obtained.
(1) Since the receiving member 1 allows the deck plate 2 to be installed below the top surface of the wooden frame 3, the thickness of the floor panel can be reduced (approximately 60%) compared to the conventional installation on beams. to some extent).
(2) Since the single deck plate 2 has high rigidity, joists can be omitted, and in-plane rigidity can be maintained even if plywood thinner than conventional plywood is attached. In addition, since sufficient rigidity is maintained, a dry type (deck plate 2 alone) and a wet type (concrete 5 placed) can be used properly according to the structural design.
(3) Since the wooden frame 3 constituting the outer periphery of the floor panel is the same as the wooden frame of the floor panel used in the conventional frame wall construction method, the conventional frame is used for joining the wall panels 20 and 30 on the upper and lower floors. It can be constructed in the same way as the wall construction method.
(4) By dropping the deck plate 2 below the upper surface of the wooden frame 3, the wooden frame 3 can be used as a formwork when pouring the concrete 5 at the time of assembly, so that formwork and removal work can be omitted. .
(5) In the present embodiment, since the notch recess 3a is formed in the upper surface of the wooden piece 3, even if the receiving member 1 is attached to the wooden piece 3, the receiving member 1 is not uneven, and is attached after that. It is possible to realize good fitting of floor materials and wall materials. Further, since the upper end level of the receiving member 1 and the wooden piece 3 is flush with each other, the wall panel 20 on the upper floor can be installed without any gap.
(6) In this embodiment, since the notch recess 3b is formed on the side surface of the wooden piece 3, the gap between the wooden piece 3 and the deck plate 2 (the thickness of the receiving member 3) is filled. It is possible to prevent leakage of concrete during concrete placement and sound leakage from the upper floors.
(7) In this embodiment, since a plurality of receiving members 1 each having a compact size are scattered to support the deck plate 2, wall panels can be provided on the upper surface of the wood 3. Flexible structural design can be realized.

8 to 12 show floor panels of a wooden building according to Example 2. FIG.
The wooden building floor panel according to the second embodiment differs from the first embodiment in that a base member 4 is interposed between the deck plate 2 and the lower flange portion 13 of the receiving member 1. do. Since other configurations are the same as those of the first embodiment, the same reference numerals are assigned and descriptions thereof are omitted as appropriate.

The base member 4 is an elongated object extending in the axial direction of the wood 3. In this embodiment, as an example, the base member 4 has a plate thickness of about 6 mm, a width of about 50 mm, and an axial length of the deck plate 2 to be used. It is implemented with a dimension equivalent to the width dimension (width dimension in the plane).

As shown in FIG. 10, the base member 4 is placed on the upper surfaces of the lower flanges 13 of a plurality of (nine in the illustrated example) receiving members 1 attached to the wood 3 . In the base member 4 according to the present embodiment, a through hole 4a is formed in advance at a position where the core of the through hole 13a of the lower flange 13 coincides with the center of the through hole 13a. After that, while the deck plate 2 is suspended and supported, the positions (centers) of the through holes 22a of the valley portions 22 at the ends thereof are aligned. Thus, the work of inserting the bolts 7 through the through holes 13a, 4a, and 22a having the same core and tightening the nuts 8 is repeated according to the number of the receiving members 1. A floor panel supported by wood 3 is realized (see FIG. 1).
For the method of attaching the receiving member 1 to the wood 3 and the method of positioning the deck plate 2 on the lower flange portion 13, see paragraphs [0023] and [0024].

Then, the wood (wooden frame) 3 of the floor panel according to the second embodiment is installed on the upper surface of the wall panel 30 on the lower floor, and the wall panel 20 on the upper floor is installed thereon. (Refer to FIG. 4 of Example 1 above).

When the receiving member 1 and the base member 4 or the deck plate 2 and the base member 4 are integrated by welding means, the through hole 4a is unnecessary.
Further, as shown in FIG. 12, the floor panel is a floor panel made by placing concrete 5 on the upper surface of the deck plate 2 to form a precast synthetic slab before being incorporated into the upper and lower wall panels 20 and 30. Alternatively, a floor slab structure may be employed in which concrete 5 is cast after being incorporated into the upper and lower wall panels 20 and 30 . Leakage of the concrete 5 can be further prevented by curing the space between the end portion of the deck plate 2 and the wood 3, or by arranging and fixing the lower flange portion 13 of the receiving member 1 and the base member 4 without a gap. It is possible and desirable.
In addition, according to the structural design, as shown in FIG. 11, the upper surface level of the deck plate 2 is made approximately the same as the upper surface level of the wood 3 by using the receiving member 1 in which the height dimension of the web portion 12 is shortened. Alignment is also possible.
The same technical concept applies to the third embodiment described below.

The floor panel of the wooden building according to the second embodiment has the same structure as that of the first embodiment, which is composed of the receiving member 1, the deck plate 2, and the lumber 3. As shown in FIG. Therefore, the same effects as those of the first embodiment described in (1) to (7) of paragraph [0026] are obtained.
In addition, the wooden building floor panel according to the second embodiment has the long base member 4 interposed between the lower flange portion 13 and the deck plate 2, so that the following effects can be obtained.
(8) Since the deck plate 2 can be installed regardless of the mounting position of the receiving member 1, flexible structural design is possible.
(9) The support strength for the deck plate 2 and the cast concrete 5 can be increased. Moreover, when concrete 5 is placed, concrete leakage can be prevented.

13 to 20 show floor panels of a wooden building according to Example 3. FIG.
The wooden building floor panel according to the third embodiment differs from the first and second embodiments in that the upper flange 11 of the receiving member 1 is inserted into the slit 3c formed in the side surface of the wooden piece 3. are different (especially see FIGS. 3 and 13, and FIGS. 8 and 17 for comparison). Since other configurations are the same as those of the first and second embodiments, the same reference numerals are given and the description thereof will be omitted as appropriate.

In short, in the floor panel according to the third embodiment, as shown in FIG. 14, the receiving member 1 having a short web portion 12 is inserted into the slit 3c formed in the side surface of the wooden piece (wooden frame) 3 so as to insert the wooden piece. 3, it is assembled by performing the same method as in Examples 1 and 2 above (see paragraphs [0023], [0024], and [0029] above).

Therefore, the floor panel of the wooden building according to Example 3 has the same structure as in Examples 1 and 2, consisting of the receiving member 1, the deck plate 2, and the wood 3. Therefore, among the above (1) to (9), the effects except for (5) are obtained.
In addition, according to the wooden building floor panel according to the third embodiment, since the upper flange portion 11 of the receiving member 1 is inserted into the side surface of the wooden piece 3, the rotating load on the receiving member 1 is reduced. When the above acts, compared with the first and second embodiments, there is no possibility that the fasteners 6 such as the screws 6 come off, and a floor panel having a very stable structure and high soundness can be realized.

Although the embodiments have been described above with reference to the drawings, the present invention is not limited to the illustrated examples, and includes the range of design changes and application variations that are normally made by those skilled in the art without departing from the technical idea of the present invention. Just in case.
For example, in the above Examples 1 to 3, the application of the floor panel of a wooden building according to the present invention to a framed wall construction method is mainly explained, but it is not limited to this, and a wooden frame construction method (conventional construction method) It is also applicable to As for the form of the floor panel, a plurality of floor panels may be joined to form a single floor panel, and the shape is not limited to a square but may be a rectangular panel such as a rectangle.
