Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a floor material mounting structure capable of forming a so-called uneven floor pattern on a floor base formed by arranging joists at a predetermined pitch.

(Problems to be solved by conventional techniques and devices) Conventionally, in order to obtain a variety of floor patterns, three types of long materials having different width dimensions are sequentially laid on a floor base, and floor finishing by so-called disordering is performed. Was being done.

However, since long materials with different width dimensions were laid one by one, the number of man-hours is large and the allocation is troublesome.
In addition to poor workability, the floor materials to be laid were sometimes placed in the wrong order.

On the other hand, in order to improve the workability, for example,
As in the flooring disclosed in Japanese Patent Publication, it is proposed to use a plurality of long materials that are arranged side by side with their end faces on the short side shifted in a substantially stepwise manner and joined and integrated in advance. Has been done.

However, with this flooring material, there is no problem when it is applied to a planar flooring material such as a concrete slab, but as in a wooden house, etc., the flooring material is applied to a flooring material formed by arranging joists in parallel at a predetermined pitch. When laying, and further laying this floor material by sequentially abutting the end portions of other floor materials, when none of the butt edges located on the same direction side of the long material is located on the joist, so to speak Since it is in a cantilever state, the subsidence of the abutted ends becomes large, and the ringing of the floor occurs due to the subduction.

On the other hand, Japanese Utility Model Laid-Open No. 63-1135 discloses a floorboard for joist construction in which long floor base materials are displaced from each other and joined.

However, in this product, the shift width is limited to the joist pitch or joist width, so if the shift width is the joist pitch (300 or 450 mm), it is too large, and if the joist width (5 to 20 mm), too small. Therefore, there is a problem that the initial purpose, that is, the appearance of the rough-finished finish with a natural texture cannot be obtained.

In order to solve the above-mentioned problems, the present invention disperses the seams of the floorboards arranged on the joists independently of the joist spacing and joist width to obtain a turbulent finish having a natural texture, Moreover, it is an object of the present invention to provide a floor material mounting structure that has good workability and is unlikely to cause sinking or floor squeal.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the flooring attachment structure according to the present invention has different width dimensions in which male and female fruits are formed at least at both ends on the short side. Of the three long members, the long member having the maximum width dimension among the three long members is arranged in parallel between the other long members, and the end face on the short side is arranged. The floor material that is joined and integrated by shifting the
Both ends of the long member having the maximum width are fixed and laid on a joist arranged in parallel at a predetermined pitch.

(Operation) Therefore, the long material having the largest bending rigidity and having the maximum width dimension in which both ends are fixed on the joist does not move the end portions of adjacent narrow materials not located on the joist. I will support you.

(Embodiment) As shown in FIGS. 1 and 2, the flooring material 1 according to the present invention has three length members 2, 3, 4 having the same length dimension and different width dimensions. It is configured by combining.

The long material 2 is provided with male seeds 5 and female seeds 6 on both end surfaces on the long side of a base material made of plywood, particle board, etc., and male seeds 7 and female seeds 8 on the both end surfaces on the short side. They are provided respectively.

Similarly to the long member 2, the long members 3 and 4 are provided with bases 5 and 7 and females 6 and 8 having different widths.

Then, the male material 5 of the long material 3 having the maximum width dimension is fitted to the female material 6 of the long material 2, and the long material 4 is fitted to the female material 6 of the long material 3.
After the males 5 of the above are fitted and arranged side by side, and the end faces of the long side members 2, 3, 4 on the short side side are staggered to be joined and integrated,
The assembling work of the floor material 1 is completed by lining the back surface of the back surface of 2, 3, 4 with a back surface connecting material (not shown).

The shift widths of the long materials 2, 3 and 3, 4 are l ₁ and m ₁ , respectively. Numeral 9 is a pseudo joint formed by adhering the decorative material 10 on the surfaces of the long materials 2, 3, and 4 and forming it irregularly.

Further, l ₂ and m ₂ are the shift widths of the pseudo joints 9 formed on the long members 2, 3 and 4, respectively.

Next, as a construction method of the flooring material 1 according to the present embodiment, for example, as shown in FIG. 1, joists 11 are arranged side by side at an equal pitch to form a flooring base, and the joists 11 of the flooring are used. There is a method in which both ends of a long member 3 having the maximum width dimension are fixed on the floor member 1 and the floor member 1 is laid, and another floor member 1 is abutted on the floor member 1 and sequentially laid.

In the flooring material 1 according to the present embodiment, three long materials 2, 3, 4 are staggered side by side and arranged side by side, and preliminarily joined and integrated, it takes time to allocate the pseudo joint 9. It is not complicated and can be constructed with a small number of steps. Therefore, the workability is good and the long materials are not laid in the wrong order.

Moreover, since both ends of the long member 3 having the maximum width dimension arranged in the center of the floor member 1 are fixed on the joists 11, so to speak, a beam is fixed at both ends, and the displacement of the long member 3 in the plate thickness direction is caused. It becomes extremely small. Therefore, the long member 3 having the greatest bending rigidity supports both end portions of the adjacent long members 2 and 3 which are not located on the joists 11 to regulate the sinking.

That is, if both ends of the long material 3 having the maximum width dimension are positioned and fixed on the joists 11 and 11, both ends of the adjacent long materials 2 and 4 are located on the joists 11. Even if it is not supported, since it is supported by the long material 3, even if a load is applied to both ends of the long material 2 and 4, the subsidence of the end of the long material 2 and 4 will be small, and the subsidence will be reduced. The floor ringing is also less likely to occur.

Further, in general, since the floor shape and size of a building are various, a gap is likely to be formed in the width direction at the beginning of the flooring or the finishing of the flooring. Conventionally, in such a case, the floor material was appropriately cut into a width to fill the gap, but according to this embodiment,
Since narrow strips are joined and integrated on both sides of the long strip having the maximum width dimension, the narrow strip located on the outermost side is separated (Fig. 2) to fill the gap. Good. As a result, it becomes unnecessary to cut a wide long material along the long side direction, the workability is improved, and the material yield is improved.

In this embodiment, the long material is joined and integrated through the male and female nuts provided on both end surfaces on the long side, but not limited to this, the end surface on the long side is a flat surface, This may be fixed and integrated with an adhesive, and the back surface connecting material is not necessarily provided.

(Effects of the Invention) As is apparent from the above description, according to the present invention, since three long materials having different width dimensions are preliminarily joined and integrated, the number of assembling steps in the field is reduced and the allocation is performed. Because it becomes easier, the workability is improved and
Do not lay the long materials in the wrong order.

Moreover, according to the present invention, among the three long members having different width dimensions, the long member having the maximum width dimension is arranged in parallel in the middle of the floor material to be joined and integrated, and has the largest bending. By fixing the both ends of the long member having the maximum width dimension having rigidity to the joist respectively, it is in a so-called two-end fixed beam state. For this reason, even if the end of the narrow long material is not located on the joist, so to speak, the long material having the maximum width dimension will not move the end of the narrow long material. Since the position is supported and regulated, there is an effect that the subsidence at the end of the narrow long member is small, and the reduction of the subside makes it difficult to generate floor ringing.
