Description

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

There is a frame wall construction method (2x4 construction method) as one of the construction methods of a wooden building. In this frame wall construction method, face materials such as flooring materials and wall materials manufactured by nailing structural plywood to a frame made of standard wood with a cross-sectional size of 2 x 4 inches are used as appropriate for wooden joint fittings. Buildings are constructed by joining them with (metal strips and anchor bolts), and their demand has been increasing in recent years because the construction period is short and the workability is good.
By the way, the floor panel of the frame wall construction method has conventionally been manufactured by forming a floor frame with a frame and joists and pasting plywood on it. The height dimension was about 235 mm because the panel material for the floor generally uses a member of 2 x 10 inches.
By the way, the floor material including the floor panel is used regardless of the frame wall construction method or the wooden frame construction method (conventional construction method) in order to improve workability, fire resistance, heat insulation, sound insulation (airtightness), etc. By devising the structure, various types of flooring materials such as the following have been developed.

For example, in Patent Document 1, construction of a house or the like that is easy to construct and can be constructed at low cost by using a panel of a composite structure in which a square timber is sandwiched between lumber core plywood (see FIG. 5) having excellent heat insulating properties. The thing and its construction method are disclosed.
In Patent Document 2, by using a panel in which a heat insulating material of foamed synthetic resin is sandwiched between plywood, an appropriate heat insulating effect can be maintained for a long period of time, excellent in fire resistance, and the thickness of the plywood is increased. Discloses structural multifunctional panels that do not require columns and beams and are suitable as constituents for walls, floors, roofs, and the like.
In Patent Document 3, the floor joists are fixed on the lower floor wall panel and a wooden floor board is laid as a lower formwork, and after the reinforcing bars are assembled, concrete is poured to form a reinforced concrete slab, and the upper floor wall is formed on the reinforcing bars. By erection of the panel, a construction method excellent in fire resistance and sound insulation is disclosed.
In Patent Document 4, notches for joining are provided at both ends in the length direction and both ends in the width direction of a precast synthetic slab main body formed by attaching a reinforcing bar to the surface of a deck plate and casting concrete, and for joining. A precast synthetic slab having excellent workability, fire resistance, and sound insulation by being installed on a beam through a notch is disclosed.

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) in order to secure the out-of-plane rigidity. .. In addition, since it is made of only wood, board-based fireproof materials and sound insulation materials are attached to ensure fire resistance and sound insulation, so the floor and ceiling are generally high (thick), and the living space is narrowed accordingly. There was a problem such as becoming.
Similar to Patent Document 1, the structural multifunctional panel according to Patent Document 2 needs to have thick plywood in order to secure in-plane rigidity, and the floor and ceiling become high (thick), and the living space is increased accordingly. There was a problem that the space became narrow.
Although the construction method according to Patent Document 3 can secure fire resistance and sound insulation, there are problems such as a concrete slab being formed on a beam or a joist, which raises the floor and ceiling and narrows the living space accordingly. there were. In addition, there was a problem that the construction period was prolonged because the concrete was placed on site.
Although the precast synthetic slab according to Patent Document 4 can also secure fire resistance and sound insulation, there are problems such as the floor and ceiling becoming higher and the living space becoming narrower because the concrete slab is formed on the beam or the joist. there were. In the first place, since the constituent members do not contain a wooden part, there is also a problem that it is difficult to connect with the wooden wall panels on the upper and lower floors in order to apply it to a wooden building.

In summary, all flooring materials that have been developed for the purpose of improving workability, fire resistance, heat insulation, sound insulation (airtightness), etc. 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, the living space can be formed wider. Although it is clear that a flexible and rational structural design can be realized and it is very useful, the techniques according to Patent Documents 1 to 4 cannot contribute to the suppression of the panel thickness, and there is room for improvement. ..

The present invention has been devised in view of the above-mentioned problems of the background technology, and an object of the present invention is that the strength and rigidity of the structure can be efficiently improved, the weight is light, and the handling property is excellent. The purpose of the present invention is to provide a floor panel for a wooden building, which makes it possible to efficiently control the height dimension of the floor panel by focusing on the deck plate and incorporating it into a wooden floor panel.

As a means for solving the above-mentioned problems, the floor panel of the wooden building according to the invention according to claim 1 is formed by bending a substantially trapezoidal corrugated cross section in which peaks and valleys are alternately connected via inclined portions.

Next, an example of the floor panel of the wooden building according to the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 3, the floor panel of the wooden building according to the present invention is formed by bending a substantially trapezoidal corrugated cross section in which mountain portions 21 and valley portions 22 are alternately connected via inclined portions 23. The deck plate 2 is a floor panel of a wooden building formed by disposing the deck plate 2 in the plane of the timber (wooden frame) 3 framed in a rectangular shape via the receiving member 1, and the receiving member 1 is the timber 3. A cross section of an upper flange portion 11 that rests on or is inserted into a side surface of the wood 1, a web portion 12 that hangs down along the side surface of the wood 1, and a lower flange portion 13 that supports a valley portion 22 at the end of the deck plate 2. It is formed in a substantially Z shape, and is provided on wood 3 on at least two opposite sides of the four sides of the frame to support the deck plate 2.

In this embodiment, the wood 3 is assumed to be the wood 3 used in the frame wall construction method. As an example, the wood according to the illustrated example is a combination of two 2 × 6 materials (about 140 mm in length), and the in-plane dimensions are formed to be, for example, about 2500 × 2500 mm.
Further, as shown in FIG. 3, the wood 3 according to the present embodiment has notch recesses 3a and 3b for positioning the upper flange portion 11 and the web portion 12 of the receiving member 1 on the upper surface and the side surface thereof. A notch recess having a substantially inverted L-shaped cross section is formed.
The shape of the notch recesses 3a and 3b is notched to the same dimensions 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 surfaces (upper surface and side surface) of the wood 3 in a state where 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 mountain portions 21 and valley portions 22 are alternately connected via an inclined portion 23, and a key groove is further provided in the valley portion 22 and a key groove is formed in the inclined portion 23. A deck plate called a synthetic slab deck plate 2 having a portion is adopted.
As an example, the dimensions of the deck plate 2 are about 600 mm in width (two mountain type), about 50 mm in height (mountain height), and about 115 to 125 mm in width of the top (flat part) of the mountain and valley parts. 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, dimensions) of the deck plate 2 is not limited to this, and the design is appropriately changed according to the structural design such as the installation area, the installation interval of the support beams, and the structurally required strength.
For example, depending on the in-plane dimensions of the wood (wooden frame) 3, it is appropriate to use a one-mountain type deck plate 2 for width adjustment having a width of about 300 mm. In addition, when concrete is not cast (dry type), a normal deck plate of the type without the keyway or the step portion can be adopted.
Incidentally, the deck plate 2 is provided with a through hole 22a (see FIG. 4) at a joint portion with the lower flange 13 of the receiving member 1 at the valley portion 22 at the end thereof.

The receiving member 1 is made of metal (steel), and is formed in a substantially Z-shaped cross section by the upper flange portion 11, the web portion 12, and the lower flange portion 13.
The upper flange portion 11 is formed with a through hole 11a for inserting a fixing tool 6 such as a screw 6, a bolt, and a drift pin used for attaching to the wood 3. Six through holes 11a according to the illustrated example are bored 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 wood 3, but the receiving member 1 and the wood 3 are displaced from each other by, for example, forming a through hole in the web portion 12 and fixing the screw 6. The fixture is not limited to the screw 6 as long as it is fixed so as not to be present, and may be fixed in any way regardless of the fixing position.
The lower flange portion 13 is formed with a through hole 13a through which a fixture 7 such as a bolt 7 used for attaching to the deck plate 2 is inserted. Two through holes 13a according to the illustrated example are bored on the left and right in a well-balanced manner, but 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.
As an example, the dimensions of the receiving member 1 are such that the width dimension of the upper flange portion 11 is about 57 mm, the height dimension (total height) of the web portion 12 is about 127 mm, and the lower flange portion 13 when viewed in the cross-sectional direction (see FIG. 3). The width dimension is about 64 mm, the plate thickness is about 6 mm, and the depth dimension (width) B (see FIG. 2) is about 110 mm.

Of course, the form (shape, size) of the receiving member 1 is not limited to this, and the design is appropriately changed according to the structural design in consideration of the form of the deck plate 2 and the wood 3.
For example, according to 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 in which the height dimension of the web portion 12 is shortened. It is also possible to align.
In addition, the receiving member 1 can be similarly implemented by combining two angle members (for example, welding and joining the back surfaces) to form a substantially Z-shaped cross section.

Next, a method (assembly procedure) for realizing a floor panel of a wooden building composed of the wood 3, the deck plate 2, and the receiving member 1 having the above configuration will be described. It should be noted that the method described below is just an example.
First, as shown in FIG. 6, a piece of wood (wooden frame) 3 framed in a rectangular shape having a predetermined size is prepared. The notch recesses 3a and 3b are formed in advance on the wood 3 (two facing sides) at a portion where the receiving member 1 is hooked. That is, in this embodiment, a total of 18 receiving members 1 are hooked, so that the wood (wooden frame) 3 is formed with a total of 18 notch recesses 3a and 3b.
Next, each of the plurality of (18 in the illustrated example) receiving members 1 is marked with the notch recesses 3a and 3b of the wood 3, and the upper flange portion 11 is used as the upper surface (notch recess 3a) of the wood 3. ), And the web portion 12 is brought into contact with the side surface (notch recess 3b) of the wood 3 so that the receiving member 1 is positioned on the wood 3. After that, the receiving member 1 is fixed to the wood 3 by passing a screw 6 through the through hole 11a of the upper flange portion 11.

Next, the deck plate 2 is lifted to a predetermined height, and the deck plate 2 is positioned and erected while being dropped between the receiving members 1 and 1.
Specifically, in order to lay the deck plate 2 in the surface surrounded by the wood 3 without a gap, the valleys 22 at both ends in the longitudinal direction of the deck plate 2 are provided with the corresponding lower flanges of the receiving member 1. Number of members 1 that are placed on the upper surface of the portion 13, have the cores of the through hole 22a of the valley portion 22 and the through hole 13a of the lower flange portion 13 aligned, and are fastened with a nut 8 through a bolt 7. A floor panel is realized in which the deck plate 2 is supported by the wood 3 via the receiving member 1 (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 further installed on it. Etc., the same construction as the conventional frame wall construction method is performed.

As shown in FIG. 7, the floor panel is formed as a precast synthetic slab by placing concrete 5 on the upper surface of the deck plate 2 before incorporating it into the upper and lower wall panels 20 and 30. It may be used, or it may be a floor slab structure in which concrete 5 is cast after being incorporated into the upper and lower wall panels 20 and 30.
Further, the receiving member 1 according to the present embodiment is implemented in a compact size having a depth dimension (width) B of about 110 mm per piece, but the present invention is not limited to this, and is long enough to cover the entire length of the wood 3. It can also be carried out with a type of receiving member (not shown). In this case, it is sufficient to attach one to each of the two opposite sides of the wood 3, so a total of two receiving members are sufficient.
The same technical idea is applied to the third embodiment described below.

According to the floor panel of the wooden building having the above structure, the following effects are obtained.
(1) Since the receiving member 1 makes it possible to drop the deck plate 2 below the upper surface of the wooden frame 3 and install it, the thickness of the floor panel is reduced (about 60%) compared to installing it on a conventional beam. Can be thinned to some extent.
(2) Since the rigidity of the deck plate 2 alone is high, the joists can be omitted, and the in-plane rigidity can be maintained even if a plywood thinner than the conventional plywood is attached. Further, in order to have sufficient rigidity, it is possible to use a dry type (deck plate 2 alone) or a wet type (concrete 5 casting) depending on the structural design.
(3) Since the wooden frame 3 constituting the outer peripheral portion of the floor panel is no different from 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 substitute for the formwork when the concrete 5 is placed during assembly, so that the formwork and the demolding work can be omitted. ..
(5) In this embodiment, since the notch recess 3a is formed on the upper surface of the wood 3, even if the receiving member 1 is attached to the wood 3, it does not cause non-landing and is subsequently attached. It is possible to realize a good fit of floor materials and wall materials. Further, since the upper end levels of the receiving member 1 and the wood 3 are flush with each other, the wall panel 20 on the upper floor can be installed without a gap.
(6) In this embodiment, since the notch recess 3b is formed on the side surface of the wood 3, the gap (thickness of the receiving member 3) between the wood 3 and the deck plate 2 is filled (filled). It is possible to prevent concrete leakage during concrete placement and sound leakage from the upper floors.
(7) In the present embodiment, since a plurality of receiving members 1 having a compact size are scattered to support the deck plate 2, a wall panel may be provided on the upper surface of the wood 3. Flexible structural design can be realized.

8 to 12 show the floor panel of the wooden building according to the second embodiment.
The floor panel of the wooden building according to the second embodiment is different from the first embodiment in that the base member 4 is interposed between the deck plate 2 and the lower flange portion 13 of the receiving member 1. To do. Since other configurations are the same as those in the first embodiment, the same reference numerals are given and the description thereof will be omitted as appropriate.

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

As shown in FIG. 10, the base member 4 is placed on the upper surface of a plurality of (9 in the illustrated example) lower flanges 13 of the 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 coincides with the through hole 13a of the lower flange 13, and the positions (cores) of the through holes 13a and 4a are aligned with each other. After that, the position (core) of the through hole 22a of the valley portion 22 at the end thereof is aligned with the deck plate 2 suspended and supported. The work of passing the bolts 7 through the through holes 13a, 4a, and 22a having the same cores and fastening the nuts 8 is repeated according to the number of the receiving members 1, so that the deck plate 2 is passed through the receiving members 1. A floor panel supported by wood 3 is realized (see FIG. 1 with reference).
Refer to the paragraphs [0023] and [0024] for a method of attaching the receiving member 1 to the wood 3 and a method of positioning the deck plate 2 on the lower flange portion 13.

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 further installed on the upper surface of the wall panel 30 on the lower floor. (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 formed as a precast synthetic slab by placing concrete 5 on the upper surface of the deck plate 2 before incorporating it into the upper and lower wall panels 20 and 30. It may be used, or it may be a floor slab structure in which concrete 5 is cast after being incorporated into the upper and lower wall panels 20 and 30. Further, if the space between the end portion of the deck plate 2 and the wood 3 is cured, or if the lower flange portion 13 of the receiving member 1 and the base member 4 are arranged and fixed without a gap, leakage of the concrete 5 can be further prevented. Is possible and desirable.
In addition, depending on the structural design, as shown in FIG. 11, 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 in which the height dimension of the web portion 12 is shortened. It is also possible to align.
The same technical idea is applied to the third embodiment described below.

The floor panel of the wooden building according to the second embodiment has the same structure as the receiving member 1, the deck plate 2, and the wood 3 as in the first embodiment. Therefore, it has the same effect as that of Example 1 described in (1) to (7) of the paragraph [0026].
In addition, the floor panel of the wooden building according to the second embodiment has the following effects because the long base member 4 is interposed between the lower flange portion 13 and the deck plate 2.
(8) Since the deck plate 2 can be installed regardless of the mounting position of the receiving member 1, a flexible structural design becomes possible.
(9) The bearing capacity for the deck plate 2 and the cast concrete 5 can be increased. Further, when the concrete 5 is cast, it is possible to prevent concrete leakage.

13 to 20 show the floor panel of the wooden building according to the third embodiment.
Compared to the first and second embodiments, the floor panel of the wooden building according to the third embodiment has a configuration in which the upper flange 11 of the receiving member 1 is inserted into the slit 3c formed on the side surface of the wood 3. (Refer to FIG. 3 and FIG. 13 and FIGS. 8 and 17 in particular). Since other configurations are the same as those in the first and second embodiments, the same reference numerals are given and the description thereof will be omitted as appropriate.

In short, as shown in FIG. 14, the floor panel according to the third embodiment is formed by inserting a receiving member 1 having a short web portion 12 into a slit 3c formed on a side surface of the wood (wooden frame) 3. After being attached to No. 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 the third embodiment has the same structure as the receiving member 1, the deck plate 2, and the wood 3 as in the first and second embodiments. Therefore, among the above (1) to (9), the action and effect excluding (5) are exhibited.
In addition, according to the floor panel of the wooden building according to the third embodiment, since the upper flange portion 11 of the receiving member 1 is inserted into the side surface of the wood 3, the load rotating on the receiving member 1 is applied. As compared with Examples 1 and 2, it is possible to realize a floor panel that is structurally very stable and has high soundness without the possibility that the fixture 6 such as the screw 6 will come off.

Although the examples have been described above with reference to the drawings, the present invention is not limited to the illustrated examples, and includes a range of design changes and application variations normally performed by those skilled in the art within a range that does not deviate from the technical idea thereof. I would like to add it just in case.
For example, in Examples 1 to 3 above, the application of the floor panel of the wooden building according to the present invention to the frame wall construction method is mainly described, but the present invention is not limited to this, and the wooden frame construction method (conventional construction method) is not limited to this. It is also applicable to. Further, regarding 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 and may be a rectangular panel such as a rectangle.
