Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a floor board for installing joists, and more specifically, to a floor board for installing joists configured so that side joint portions do not overlap in a straight line.

[Conventional technology]

Traditionally, floorboards in buildings with a joist structure have a width x length of 1 shaku x 6 shaku (approximately 30 cm x approximately 180 cm).
For example, there was a floorboard with an irregular pattern as shown in Figure 4.

[Problem that the invention attempts to solve]

However, in the case of the floorboards with the irregular pattern described above, as shown in Figure 4, even though the horizontal joints of the flooring pieces are arranged in an irregular pattern so that they do not overlap in a straight line, When the floorboards were attached one after another, a straight seam at both ends of the floorboards always appeared, which was unsightly in terms of design.

The purpose of this invention is to solve the above-mentioned problems and to create a joist construction that does not require much effort in construction, and that allows the horizontal joints to not overlap in a straight line even when pasted in sequence, creating a floor surface with excellent design. Our goal is to provide suitable floorboards.

[Means for solving problems]

Therefore, the configuration of the present invention for solving the above conventional problems will be explained using the drawings of the embodiment.
The floor board 1 for installing joists of the present invention is characterized in that it is formed by joining a plurality of long floor base materials 11, 12, .

The long floor base materials 11, 12, . . . each include a plurality of flooring pieces 11a, 11b, .
2a, 12b, ... are preferably formed by shifting and joining them at intervals smaller than the width of the joists,
For example, in the floorboard shown in FIG.
It is composed of b.

The number of flooring pieces constituting the long floor base material is not limited, and may be three as shown in Figure 2, or may be one as shown in Figure 3. It can be done.

[Effect]

Since the present invention is constructed as described above, the end of the floor board is located on the joist, so it is easy to install and has great strength. The individual flooring pieces that make up the flooring are joined at intervals smaller than the width of the joists, so the joints do not overlap horizontally.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of one embodiment of the floor plate for joist construction of the present invention.

In the figure, 1 is a floor plate for joist construction;
1 and 12 are long floor base materials, 11a, 11b, 12
a, 12b are flooring pieces, 2a is male fruit,
2b is the female fruit, and 3 is the joist. The floor board 1 is composed of long floor base materials 11 and 12, and the long floor base materials 11,
12 are flooring pieces 11a and 11, respectively.
b, 12a, and 12b. The flooring pieces 11a and 11b are joined at the end faces in the longitudinal direction while being offset by an interval smaller than the width of the joists 3. Normally, the width of joist 3 is approximately 40mm.
~45 mm, so it is appropriate to shift 11a and 11b by about 5 mm to 20 mm. 12a and 12b are also joined in exactly the same way. Furthermore, long floor base materials 11 and 1
2 and 2 are connected to each other by being shifted by the interval of the joist 3. Since the usual spacing between joists is 300 mm or 450 mm, the spacing between the long floor base materials 11 and 12 is determined according to that spacing. The floorboard 1 configured in this manner is manufactured in advance at a factory, and this size is convenient for packaging the floorboard or transporting it from the factory to a construction site. Furthermore, when using four flooring pieces, it is better to form them as described above in terms of strength than to shift them one by one at the intervals of the joists.

Next, construction of this floorboard 1 will be explained. The floorboard 1 is attached so that its end is located on the joist 3, but the male sap 2a of the floorboard 1 is first fixed to the joist 3, then the female 2b is fitted with the male joist 2a,
The floorboards 1 are attached one after another. Installing the floorboard 1 is easy because the male 2a and female 2b are simply fitted together on the joist 3, and since there is a step at the end of each long floor base material, there is no horizontal seam. There will be no overlap.

In the above embodiment, the floorboard is composed of four flooring pieces, but as long as the structural requirements of the present invention are satisfied, the present invention is not limited to the above embodiment, and the floorboards shown in FIGS. 2 and 3 can be used. Other embodiments as shown are also possible. In FIG. 2, flooring pieces 11a, 11b, 11c are joined together at intervals smaller than the width of the joists to form a long floor base material 11, and similarly, 12a, 12b, 12
A long floor base material 12 was formed from c, and the floor board 1 was obtained by joining these materials while shifting them from each other by the interval of the joists.
In FIG. 3, a floorboard 1 was obtained from elongated base materials 11 and 12 each consisting of one flooring piece.

[Effect of idea]

Since the present invention has the above-mentioned configuration, it is easy to attach the floorboards, and the attachment strength of the floorboards to the joists is high.Moreover, the long floor base material that makes up the floorboards and the flooring pieces that make up the floorboards can be staggered. Since they are joined together, even if the floorboards are attached one after another, the horizontal joints will not overlap, resulting in an excellent design.
