Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor member which is arranged at an end of a floor when a rectangular floor decorative material is laid on the underground of a veranda, a rooftop or the like, and a laying structure thereof. About.

[0002]

2. Description of the Related Art Artificial turf has been laid on the floor of a veranda, a rooftop or the like for the purpose of improving aesthetics.

[0003] Recently, in order to construct a high-quality floor with comfortable feet, a construction method of laying a plurality of floor decorative materials on the lower ground of a veranda or a rooftop has been adopted. It has become to. As the floor decorative material, a material in which a decorative surface material such as synthetic resin, rubber, wood, or tile is integrally formed on the upper surface of a floor material main body (mat) formed by forming a hard synthetic resin into a rectangular shape is used. (For example, Japanese Utility Model Laid-Open No. 5-85929).

[0004]

However, among the above floor decorative materials, as disclosed in Japanese Utility Model Laid-Open No. 5-85929,
If the decorative surface material is a relatively heavy material such as a tile, the effect is not so large. However, if the decorative surface material is a synthetic resin or the like and the floor decorative material as a whole is lightweight, the influence of outdoor wind becomes a problem.

For example, as shown in FIG. 1, when a lightweight floor decorative material 11 is spread over a veranda V with handrails, wind passing through a handrail P at the end of the veranda enters the lower surface side of the floor decorative material 11. There is a possibility that the entire floor decorative material is rolled up and blown off.

Further, when wind blows on the upper surface of the floor decorative material laid on a veranda or the like, a flow of wind along the upper surface creates a negative pressure state on the upper surface side of the floor decorative material. Cosmetic material may be rolled up.

[0007] The present invention has been made in view of such circumstances, and can prevent the effect of wind applied to a floor decorative material laid on a veranda, a rooftop, etc. (winding of the floor decorative material, etc.). An object of the present invention is to provide a floor member and its laying structure.

[0008]

In order to achieve the above object, a floor member according to a first aspect of the present invention has a vertical cross section, as shown in FIG. The height h1 from the lower surface of the protruding portion 1b having a right-angled triangular cross section to the lower end of the floor member 1 (the lower surface of the main body portion 1a) is a floor decorative material 11
It is characterized by being machined to dimensions approximately equal to the height of

As shown in FIG. 3, the floor member according to the first invention is disposed along one side of the floor decorative material 11, and is used by covering the upper surface of the floor decorative material 11 with a projection 1b having a right-angled triangular cross section. I do. And in the use state, the end of the floor decorative material 11
Since the floor member is closed by the main body portion (a portion having a substantially rectangular cross section) 1a, wind does not blow on the lower surface of the floor decorative material 11. In use, the projection 1b has a right-angled triangle cross section.
Is located above the upper surface of the floor decorative material 11, the portion becomes a wall, and the flow of wind along the upper surface of the floor decorative material 11 is blocked, whereby a strong wind is blown on the floor decorative material 11. However, the degree (magnitude) of the negative pressure generated on the upper surface side can be small. As a result, it is possible to prevent the floor decorative material 11 from rolling up.

In order to achieve the same object, the floor member according to the second aspect of the present invention, as exemplified in FIG. The height of the floor member 2 from the lower surface (the lower surface of the main body 2a) to the height of the floor decorative material 11 is approximately equal to the height of the floor decorative material 11. It is characterized by having been.

The same applies to the floor member of the second invention. As shown in FIG. 5, the floor member 11 is disposed along one side of the floor decorative material 11 and the projection 2b having a rectangular cross section is placed on the upper surface of the floor decorative material 11. By using this, the main body 2 a having a substantially right-angled triangular cross section functions as a windshield, and it is possible to prevent wind from blowing on the lower surface of the floor decorative material 11.

In the flooring material of the second invention, the height of the portion projecting above the floor decoration material 11, that is, the protrusion 2 b having a rectangular cross section is not so high, and the flow of wind along the upper surface of the floor decoration material 11 is small. Although the effect of blocking wind is small, there is an advantage that the wind can be reliably prevented from blowing into the lower surface of the floor decorative material 11 because the front side of the main body 2a serving as a windshield is an inclined surface.

In order to achieve the same object, the floor member according to the third invention is a horizontally long member having a substantially F-shaped longitudinal section.
Out of two parallel sides of the character shape, the length of the outer side is larger than the height of the floor decorative material 11, and the length of the inner side is processed to be smaller than the height of the floor decorative material 11. Characterized by

In the floor member according to the third aspect of the invention, as shown in FIG. 7, a portion forming a vertical side of the F-shape (base portion 3a) is placed below the floor decorative material 11, and an outer side of the F-shape is formed. The end (the vertical leg 11a or the like) of the floor decorative material 11 is used between the portion to be formed (vertical portion 3b) and the portion forming the inner side (vertical portion 3c).

In the state of use, the outer vertical portion 3
Since b functions as a windshield, wind does not blow on the lower surface of the floor decorative material 11. Moreover, the outer vertical part 3
Since b is in a state protruding from the upper surface of the floor decorative material 11,
The protruding part becomes a wall, and the flow of wind along the upper surface of the floor decorative material 11 is blocked. Therefore, in the floor member according to the third aspect, the floor decorative material 11 can be prevented from being rolled up.

On the other hand, in the laying structure of the present invention, as exemplified in FIG. 9, a main body 4a for closing the end of the floor decorative material 11 and a projection 4b for suppressing the floating of the floor decorative material 11 are integrally formed. In arranging the floor member 4 at the end of the floor constituted by the laying of the floor decorative material 11, the floor member 4 is characterized in that it is bonded and fixed to the base F, and thus the floor member 4 is bonded. By fixing, it is possible to more effectively prevent the floor decorative material from being displaced or rolled up due to strong wind.

Further, in such a laying structure, if the floor member 4 is connected to the floor decorative material 11, further effects can be expected. When connecting the floor member 4 to the floor decorative material 11 when both connecting portions of the floor member 4 and the floor decorative material 11 are male connecting portions (or female connecting portions), FIGS.
2 may be used.

In the present invention, the material of the floor member is not particularly limited. However, in consideration of workability at the time of laying and harmony with the floor decorative material, a hard synthetic resin having the same strength as the floor decorative material is preferable. Further, the length of the floor member is preferably set to a dimension equal to the length of one side of the floor decorative material 11 in consideration of workability at the time of handling / construction, but may be longer.

Here, this type of floor decorative material, particularly a floor decorative material in which a resin surface material is integrally formed with a frame, is liable to be thermally expanded and contracted due to a temperature difference between daytime and nighttime. When the end of the floor surface is fixed by the floor member, surface irregularities may be generated due to thermal expansion and contraction, and the fitting state of the floor decorative material may be deteriorated.

In order to prevent this, in the present invention, when the floor member is connected to the floor decorative material, the construction method is adopted in which the connection is performed via a member having a function of absorbing thermal expansion and contraction of the floor decorative material. I do.

As a specific means, as shown in FIGS. 14 and 15, the floor decorative material 110 is divided into a main body 111 and a connecting mechanism 112, and the end of the main body 111 is connected to the connecting mechanism 112. Are provided with locking portions 111a and 112a which are respectively engaged with each other, and the coupling mechanism 1
By making the dimension C of the locking concave portion 12 larger than the dimension D of the locking convex portion on the side of the main body 111 (C> D), it is possible to provide a certain amount of allowance for these locking connecting portions, so And absorbs the thermal expansion and contraction of the floor decorative material.

Further, in the laying structure of the present invention, FIG.
