Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor plate supporting device in a floor structure, which is designed to be attached to joists placed between beams or installed on the beams.

[0002]

2. Description of the Related Art FIG. 4 is a layout view of beams and joists on the second floor of a house. In the figure, (1) (1) ... are floor beams of the second floor arranged in parallel to each other, and (2) (2) ... are those floor beams.
(1) (1) ... joists passed between them, (3) (3) ... indicate independent columns standing on the floor beam (1). In addition, this independent pillar (3)
Corresponding to the position of the floor beam (1) (1) ... beam connection (4) connecting between
(Hereinafter referred to as a connecting beam) is provided. Furthermore, in this connecting beam (4) part, as shown in FIG.
A joist (2) consisting of a square pipe is pre-mounted on (1).

In the above structure, for example, FIG.
When the upper part of the connecting beam (4) of a part of the connecting beam (4) serves as a partition wall of the second floor, a plate (for connecting the vertical brace (5) to the upper surface of the end of the connecting beam (4) is used. 6) may be attached. For this reason, the joist (2) previously provided on the connecting beam (4) is shorter than the beam (4) so as to avoid the mounting portion of the plate (6).

[0004]

Accordingly, the brace (5)
The joist (2) is in a defective state at the portion where the plate (6) for use comes in, and therefore, there is no inconvenience that there is no support for the floor plate on the joist (2) at this missing portion.
In this case, only the part where the plate (6) is attached is joisted.
It is possible to shorten (2) and lengthen other parts (for example, the joist on the right side of Fig. 5), but if this is done, the types of joists (2) and beams (4) will increase, and However, it takes time to select the beam, etc. For this reason,
Conventionally, a short joist with the end cut out as described above
With the (2) as a standard product, the joists (2) of the same length are used regardless of the presence of the plate (6), and inevitably, each part is not supported by the joists (2). Floorboard
The part (2) occurs.

FIG. 6 shows the layout of the floor board (7).
As you can see in this figure, in the short joist (2),
In the range of the notched length L, the joists 2 are supported in a cantilever manner from the joists 2 adjacent to the joists 2 in parallel, which causes a problem of floor squeal.

The present invention has been made for the purpose of eliminating the above-mentioned conventional drawbacks and preventing floor squeal at the floor plate portion where the end of the joist is missing.

[0007]

In order to solve the above problems, according to the present invention, a floor plate is fixed on a joist placed between the beams, and the beam is previously attached to the beam upper surface corresponding to the end of the floor plate. It is characterized in that the supporting metal fittings are fixed by utilizing the formed bolt holes, and the end portions of the floor plate are supported by the supporting metal fittings. In this case, as the bolt holes, standard bolt holes provided on the beam at a standard pitch are usually used.

In the above-mentioned invention, in the invention of claim 2, the supporting metal fitting is a substantially Z-shaped structure composed of upper and lower horizontal pieces and vertical pieces connecting the horizontal pieces when viewed from the side, and the lower horizontal piece is It is fixed to the beam, and the floor board end is placed on the upper horizontal piece.

[0009]

As described above, since the end portion of the floor plate having a missing joist is supported by the supporting metal fittings, floor squeal as in the conventional case does not occur. Further, since this support fitting is attached using standard bolt holes formed in the beam in advance at the reference pitch, special bolt hole processing is unnecessary.

[0010]

1 and 2 show an embodiment in which the support fitting of the present invention is attached at the same position as in FIG. The support fitting (11) is formed by bending a steel plate into a substantially Z shape when viewed from the side, and is a vertical piece that connects the upper and lower horizontal pieces (12) (13) and the horizontal pieces (12) (13). It consists of a piece (14). The lower horizontal piece (13) has a pair of bolt holes (15) (1) for fixing it on the floor beam (1) or the connecting beam (4).
5) is formed.

The floor beam (1) is formed with four bolt holes for bolts (17), (17) ... For fixing the horizontal plate (16) at the lower end of the independent column (3). In addition to that, floor beams (1)
Two bolt holes with a certain pitch on both sides in the longitudinal direction
(18) (18) is formed as a standard, first of all, this bolt hole
(18) Utilizing (18), the lower horizontal piece (1
The bolt holes (15) and (15) of 3) are aligned with the bolt holes (18) and (18), and the bolts (19) and (19) inserted from above are fixed. In this embodiment, the upper horizontal piece (12) is attached so as to project to the side opposite to the independent pillar (3), but the upper surface of the upper horizontal piece (12) has a height of a joist (2 )
Is the same as the height of. It is also possible to install it in the opposite direction.

Further, the connecting beam (4) is provided with two bolt holes (20) (20) in the widthwise direction at its end as standard. In this embodiment, as described above, One connecting beam (4)
The plate (6) for connecting the vertical brace (5) is attached to the bolt using the bolt hole (20) (20), but in the other connecting beam (4), the bolt hole (20) ( The support fitting (11) is attached to 20) in the same manner as described above.

Further, since the support fittings (11) are Z-shaped as described above and the bolt holes (15) are exposed upward, it is easy to tighten the bolts (20) from above. is there.

FIG. 3 shows a beam to which the above-mentioned support fitting (11) is attached.
The arrangement of (1) and (4) and the floor board (2) is shown. As shown in this figure, the end portion of the floor board (7) is attached to the floor beam (1) and the connecting beam (4) by a supporting metal fitting ( It will be supported by 11), and floor ringing at this part can be prevented.

In this embodiment, the floor beam (1) and the connecting beam are
Although the support fittings (11) are attached to both sides of (4), they may be attached to only one if not necessary. Furthermore, not only such an independent pillar (3) peripheral part but also a joist (2)
It can also be used for other regions where the is missing.

[0016]

As described above, according to the present invention, the size of the joist used as a standard product is short, and therefore, the floor plate portion in which the end of the joist is missing is supported by the supporting metal fittings. This has the effect of eliminating such a defect that causes floor noise. On the other hand, as described above, it is not necessary to change the size of the joist by distinguishing the place where the plate for brace or the like is attached on the beam and the place where it is not attached.By using standard products of the same size for these, the joist or its It is possible to obtain the effect that it is not necessary to increase the number of types of connecting beams to which joists are attached. In addition, since the support fitting uses standard bolt holes that are usually formed in the beam, no special bolt hole processing is required.
