Description

  The present invention relates to a floor board material that includes a cellulosic fine particle and a resin and is installed in an installation part.

A plurality of deck materials (floor board materials) are laid on the floor such as a veranda, a balcony, and a rooftop. As a method of laying the deck material, for example, a lower deck material having a concave cross section opening on the upper surface is installed on the floor surface, and an upper deck material having a concave cross section opening on the lower surface is inserted and installed in the lower deck material. Later, a case is disclosed in which the deck material is fixed on the floor surface by screwing the screw from the upper surface of the upper deck material toward the floor surface (see, for example, Patent Document 1).
However, in the laying method described in Patent Document 1, the screw screwed from the upper surface of the upper deck material toward the floor surface has the screw head locked on the upper surface of the upper deck material, Is embedded in the floor surface, and the screw portion between the head portion of the screw and the tip portion is inserted into the hollow portion. In other words, since the width of the hollow portion is formed wider than the diameter of the screw, this screw is locked only at its head and tip, and usually this is how to fix the deck material to the floor surface. Although sufficient, in recent years it has been desired to securely and firmly fix the deck material to the floor surface.
Therefore, as the deck material, a plurality of cavities are formed at predetermined intervals in the width direction of the long plate material, and at least one of the cavities is a fastening material for fastening the plate material to the floor. The width of the insertion portion is formed to be substantially equal to the diameter of the fastening material. Furthermore, an engagement protrusion that engages with the fastening material is formed on the inner wall surface of the insertion portion, or an abutting portion on which the head portion of the fastening material can abut on the inner wall surface of the insertion portion. Thus, there is known a technique in which the fastening material is reliably installed on the floor without coming out of the insertion portion (see, for example, Patent Document 2).
Japanese Utility Model Publication No. 54-16020 Japanese Patent Laid-Open No. 2003-3660

However, in the deck material described in Patent Document 2, the insertion portion formed in the plate material has a width almost equal to that of the fastening material, and an engagement protrusion is formed on the inner wall surface. Is almost constant, the fastening material does not come off from the insertion portion, but it is still not sufficient. There is also a deck material in which an abutting portion with which the head of the fastening material abuts is formed on the inner wall surface. In this case, the cross-sectional shape of the insertion portion is substantially I-shaped. Since the contact portion is formed substantially perpendicular to the inner wall surface of the insertion portion (substantially horizontal to the surface of the plate material), it is easy to drive the fastening material into the contact portion when the fastening material is driven. It was difficult to position the dressing in the horizontal direction.

Further, the width D of the insertion portion 4 in the vicinity of the surface of the plate 2 is formed larger than the diameter of the screw B.

  Furthermore, a plurality of small grooves 7 are formed on the back surface of the plate 2 (the lower surface of the plate 2 in FIG. 1) along the extrusion direction formed when the plate 2 is extruded. Note that the surface of the plate 2 (the upper surface of the plate 2 in FIG. 1) is a substantially flat surface.

  Further, on the left and right side surfaces of the plate member 2, long grooves 8 that are recessed inward along the extrusion direction of the plate member 2 are formed. The groove 8 is fitted with a mounting bracket 9 to be described later for connecting the floor boards 1 installed adjacent to each other on the left and right.

On the other hand, for example, by pulverizing containers, packaging, trays, etc. of foods containing beverages with a known pulverizer, polypropylene resin, polyvinyl chloride resin, polyethylene resin, foamed vinyl chloride resin, polystyrene resin, ABS resin, etc. Obtain a resin.

Then, the cellulosic fine particles and the resin are mixed, and the mixed material is heated and melted by an extrusion molding machine to perform extrusion molding, thereby manufacturing the floor board material 1 formed into a plate shape.
The metal mold | die used with an extrusion molding machine shall be provided in the location where the shape similar to the cross-sectional shape of the cavity part 3, the small groove 7, and the groove part 8 mentioned above should be formed.
The floor board material 1 manufactured in this way is formed with the cavity 3, the small groove 7 on the back surface, and the groove 8 on the side surface at the same time.

Then, as shown in FIG. 2, when installing the floor board material 1 on the joist 10 made of, for example, aluminum, first, on the end of the joist 10 with the back surface on which the small groove 7 is formed as the lower surface And placed so that their longitudinal directions are orthogonal. Next, the floor board material 1 is fixed onto the joists 10 by inserting screws B through the insertion part 4 from the upper surface of the board material 2.
Next, the mounting bracket 9 is locked to the rail portion 11 of the joist 10 and fixed with screws B. At the same time, this mounting bracket 9 is fitted into the groove portion 8 of one floor board material 1 fixed to the joist 10 first. The screw B is fixed on the side surface of the one floor board material 1.
Then, the other floor board material 1 is installed on the joist 10 so that the groove portion 8 is fitted into the mounting bracket 9 so as to face the side surface of the floor board material 1.
Subsequently, the next mounting bracket 9 is screwed to the rail portion 11 of the joist 10 and the groove portion 8 of the other floor board material 1, and the next floor board material 1 is further installed on the joist 10. Repeat. (In FIG. 2, it is assumed that the floor board material 1 and the mounting bracket 10 are installed from the left side of the joist 10. Also, the rail portion 11 is formed so that the upper surface of the joist 10 has an upper surface opened. .)

In FIG. 2, only the floor board material 1 positioned at the end of the joist 10 is fixed by inserting the screw B from the insertion part 4, but the other floor board material 1 is similarly connected to the insertion part 4. It may be fastened with screws B.
Further, regarding the installation of the floor board material 1, it is possible to install it on the joists 10 with the surface of the flat surface as the lower surface, without using the back surface on which the small grooves 7 are formed as the lower surface.
Furthermore, the floor boards 1 that are adjacent to each other may be connected by other connection methods without using the above-described mounting bracket 9 in particular.

Further, as a modification of the floor board material, as shown in FIG. 3, instead of the insertion part 4 having a generally gourd-like shape in front sectional view, a substantially pentagonal cavity 4A in a front sectional view is provided so as to face each other. Also good. In this case, it is assumed that the distance d between the two substantially pentagonal cavities 4A is smaller than the diameter of the screw B described above.
Furthermore, there may be a plurality of inclined portions 5 and fixed portions 6 on both inner wall surfaces instead of one each. For example, in the case of FIG. 4, there are two inclined portions 5B and two fixed portions 6B on the inner wall surfaces on both sides of the insertion portion 4B, and further, the inclined portions 5B are inclined in the opposite direction to the inclined portions 5B. Two reverse inclined portions 5b and two fixed portions 6b are provided. The reverse inclined portion 5b is inclined in the opposite direction to the inclined portion 5B so that the width of the insertion portion 4B is smaller than the diameter of the screw B.

As mentioned above, according to the floor board material 1 of the 1st Embodiment of this invention, the inclination part 5 which inclines so that it may become small toward the insertion direction of the screw | thread B on the both-side inner wall surface of the insertion part 4, and an inclination Since the fixing part 6 formed at the tip of the part 5 and to which the screw B is fixed is provided, the fixing part 6 is almost straight when the screw B is guided along the inclination direction of the inclined part 5. Can be inserted. Thus, the positioning of the screw B in the horizontal direction can be easily performed by the inclined portion 5, and the screw B can be securely and firmly fixed to the plate member 2.
In addition, the fixed portion 6 is composed of a tip portion of one inclined portion 5 and a tip portion of the other inclined portion 5, and the distance d between these two tip portions is smaller than the diameter of the screw B. When inserted between the tip portions, the screws B are pressed from the periphery by the fixing portions 6 and are securely and firmly fixed to the plate member 2.
Furthermore, since the width D of the insertion portion 4 in the vicinity of the surface of the plate member 2 is larger than the diameter of the screw B, the screw B can be easily inserted into the insertion portion 4, and the operation can be performed smoothly.
Since the board 2 is made of cellulose-based fine particles obtained from the wood waste and resin obtained from the resin waste, the wood powder appears on the surface of the board 2 to give a feel and texture closer to natural wood. It can be set as the floor board material 1 with a wooden texture. Furthermore, since waste materials are used, it is excellent from the viewpoint of effective use of resources and environmental protection.

Next, a second embodiment of the present invention will be described.
FIG. 2 is a front sectional view of a floor board material according to a second embodiment of the present invention.
The floor board 1C of the second embodiment of the present invention is different in shape from the fixing portion 6 of the first embodiment, so only that point will be described, and similar constituent parts will be denoted by the same reference numerals. The description is omitted.
As shown in FIG. 2, in the present embodiment, the fixing portion 6C includes a tip portion of an inclined portion 5C provided on one inner wall surface forming the insertion portion 4C and an inclined portion formed on the other inner wall surface. The end portion of 5C is integrally formed continuously in the width direction of the insertion portion 4C, and the inside of the insertion portion 4C is vertically divided by the fixing portion 6C.
The fixed portion 6C has a substantially flat surface, and the thickness thereof is thinner than the thickness of the inclined portion 5C so that the screw B can penetrate.

As mentioned above, according to the floor board material of the 2nd Embodiment of this invention, as for the fixing | fixed part 6C, the front-end | tip part of one inclination part 5C and the front-end | tip part of the other inclination part 5C are in the width direction of the insertion part 4C. Since the screw B is formed so as to be continuous and thinner than the inclined portion 5C so that the screw B can penetrate, the screw B passes through the fixing portion 6C, so that the screw B It is pressed from the surroundings and securely and firmly fixed to the plate member 2 without coming off or shifting.
Moreover, since the thickness of the fixing | fixed part 6C is thin, the screw | thread B can be penetrated easily to the fixing | fixed part 6C, and an operation | work can be performed smoothly.
In addition, since the same effect can be acquired about the component similar to 1st Embodiment, the description is abbreviate | omitted.

In addition, this invention is not limited to the said embodiment, It shall change suitably in the range which does not deviate from the summary.
For example, as a modification of the second embodiment, the inclined portions 5C and the fixed portions 6C are not provided one on each of the inner wall surfaces on both sides, but a plurality of inclined portions 5D and fixed portions 6D are provided as shown in FIG. Also good.

  In the first embodiment, the plurality of small grooves 7 are formed on the back surface of the plate 2 and the surface is substantially flat. However, the surface also has a plurality of depths and widths different from the back surface. May be formed (not shown). In this case, since two types of patterns are applied on the front and back surfaces, it can be easily switched to a floor board material with different small grooves formed, the range of applications is widened, construction work is simplified, and the construction period Can be shortened, leading to cost reduction.

Further, an insertion hole (not shown) through which the screw B can be inserted may be formed on the surface of the plate member 2 to reach the insertion portion 4. By forming the insertion hole in this manner, the insertion location of the screw B is easy to understand, and the operation can be smoothly performed without erroneously inserting the screw B into a location other than the insertion portion 4.
In particular, the insertion hole is preferably a long hole that is long in the extrusion direction of the plate member 2. Even if the plate material 2 is contracted due to drying or expands with moisture when the plate material 2 is installed, the screw B is inserted through the long hole, and the contraction or expansion is performed in the long hole. This is because the screw B inserted through the long hole is not affected by the contraction or expansion of the plate member 2 and can be fixed via the screw B.
Furthermore, the shapes of the hollow portions 3a and 3c other than the insertion portion 4 are not limited to those described above, and can be changed as appropriate.
