Description

  The present invention relates to artificial wood.

In recent years, artificial wood formed by extrusion molding using a synthetic resin material has been widely used as a flooring for a balcony. As the artificial wood, a bottom plate portion, a plurality of standing plate portions rising from the bottom plate portion, and a top plate portion provided between the plurality of standing plate portions are formed to be long in one direction. In addition, in order to reduce the weight of the flooring and the like, a structure having a hollow portion formed in the longitudinal direction inside is well known.
Since such artificial wood has a hollow portion, it has poor rigidity and is likely to bend and twist.
Therefore, the reinforcement method which inserts mortar and steel materials in the hollow part of artificial wood conventionally is developed (for example, the following patent document 1).
The hollow synthetic wood reinforcing method described in Patent Document 1 is a method of inserting a deformed steel bar in which an iron wire is wound around an artificial wood such as a synthetic wood rung or a synthetic wood pillar, and fixing it with bolts, and then attaching mortar to the hollow portion. Filled.

  However, in the artificial wood of Patent Document 1, there is a problem that the construction work becomes complicated because the steel material must be fixed by a fixing tool such as a bolt to be positioned in the hollow portion and further filled with mortar. Moreover, since the artificial wood of patent document 1 is a structure which fills a hollow part with mortar, there existed a problem that the weight of artificial wood became large and it was difficult to convey and lay artificial wood.

  The present invention has been made in view of the above circumstances, and provides an artificial wood that is easily reinforced and lightweight.

The artificial wood of the present invention includes a bottom plate portion formed so as to extend in one direction, a plurality of standing plate portions that stand up from the bottom plate portion and extend along the one direction, and the plurality of standing stands. A top plate portion provided between the plate portions, and at least one of the bottom plate portion, the upright plate portion, and the top plate portion, the bottom plate portion, the top plate portion, and the upright plate. The support part which supports the reinforcement member inserted in the hollow part formed by the part is formed.
According to this configuration, simply by inserting the reinforcing member, the reinforcing member can be easily positioned at a predetermined position of the hollow portion by the support portion and can be arranged without wobbling.

The support portion of the present invention protrudes from the inner wall surface of at least one of the bottom plate portion, the standing plate portion, and the top plate portion toward the hollow portion, and intermittently or continuously in the one direction. Alternatively, a plurality of protrusions formed in parallel to each other may be used.
According to this configuration, the reinforcing member can be prevented from wobbling in the hollow portion, and the protrusion itself can serve as the reinforcing member.

In the artificial wood according to the present invention, a long reinforcing member provided so as to extend in the one direction may be inserted into any one of the hollow portions.
According to this configuration, any one of the operations and functions described above can be achieved.

Hereinafter, an artificial wood according to an embodiment of the present invention will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the artificial wood 1 </ b> A according to the present embodiment is a synthetic resin wood used for floor materials, wall materials, blindfold louvers, and the like, and a reinforcing member 3 </ b> A that reinforces rigidity in the hollow portion 2. Can be inserted.

  The artificial wood 1A has a bottom plate portion 4 formed so as to extend in one direction L (the depth direction in FIG. 2 and thereafter), and a plurality of the artificial wood 1A rising from the bottom plate portion 4 and extending along the one direction L. , And a top plate portion 6 provided along one direction L across the plurality of standing plate portions 5, 5..., A bottom plate portion 4, and a standing plate portion 5. At least one of the top plate portion 6 and the top plate portion 6 is formed with a support portion 7 that supports the reinforcing member 3A inserted into the hollow portion 2 formed by the bottom plate portion 4, the top plate portion 6, and the standing plate portion 5. It is characterized by being.

  In the present embodiment, the upright plate portions 5 that are vertically raised between the bottom plate portion 4 and the top plate portion 6 that is disposed opposite to the bottom plate portion 4 are formed at regular intervals, and the outer shape in a side view is rectangular. A plurality of hollow portions 2 are formed in a direction orthogonal to one direction L. The support portion 7 is formed in the shape of a strip-shaped protrusion 8 on the inner wall surface 6 s of the central hollow portion 2 among the plurality of hollow portions 2.

  The protrusion 8 has a protruding dimension that can substantially fill the gap formed between the reinforcing member 3A and the inner wall surface 6s when the reinforcing member 3A of the square pipe as shown in FIG. 2 is inserted into the hollow portion 2. It is provided on the inner wall surface 6s so as to extend in one direction L.

The material of the artificial wood 1A may be formed of only a synthetic resin such as polyethylene, polypropylene, ABS, AES, and it is more preferable that wood powder, fly ash, or the like is mixed with these synthetic resins.
The material of the reinforcing member 3A is preferably iron, stainless steel, aluminum or the like. It is even better if the iron is plated or treated with rust.

  Thus, conventionally, when using artificial wood for a blindfold louver that is fixed to a wall surface or the like, it is necessary to increase the fixing pitch from the design surface or the like, so that the viewpoint of improving the fixing strength and product strength and preventing thermal deformation Therefore, it was necessary to reinforce by inserting a steel material or the like inside.

In this regard, according to the artificial wood 1A, with the above-described configuration, for example, a reinforcing member 3A such as a steel material that is commercially available with a quadrangular prism shape can be easily installed in the hollow portion 2, and the artificial wood 1A can be easily installed. The effect that reinforcement can be aimed at is acquired. That is, since the protrusions 8 are continuously formed along the forming direction of the hollow portion 2 (that is, the direction of the arrow L shown in FIG. 1), the frictional resistance with the reinforcing member 3A can be reduced, and the reinforcing member 3A. Can be easily inserted into the hollow portion 2.
In addition, according to the artificial wood 1A, it is possible to easily perform the construction using the lightweight reinforcing member 3A, and to obtain an effect that the construction can be stably fixed for a long period after the construction.

In addition, since conventional artificial wood has relatively poor rigidity and is likely to bend and twist due to thermal deformation, for example, when used for flooring, joist made of plated steel plate, aluminum, wood, etc. It was necessary to shorten the pitch to arrange the.
In this respect, according to the artificial wood 1A, since the artificial wood 1A can be reliably reinforced by the reinforcing member 3A, even if it is used for a flooring or the like, the joist is used because it is the artificial wood 1A. The effect that the necessity to shorten the pitch to arrange | position is reduced is acquired.

  And, when using a commercially available steel material to reinforce a conventional artificial wood by inserting a reinforcing member such as a steel material into the interior, the outer shape is limited if the artificial wood is designed by adjusting the thickness of the artificial wood. It was difficult to design with optimal design and optimal strength. In addition, when designing an artificial wood with an optimal external shape and thickness, the dimensions of the steel material to be inserted are limited, and the size of the commercially available product may not match.

  However, according to the artificial wood 1A, since the gap between the inner wall surface 6s and the reinforcing member 3A can be adjusted by the protrusion 8 formed in the hollow portion 2, the entire outer shape of the artificial wood 1A or the entire bottom plate portion 4 or the like. It is possible to avoid setting the wall thickness to match the size of the reinforcing member 3A. That is, in the artificial wood 1A, the clearance between the inner wall surface 6s and the reinforcing member 3A may be adjusted by the protruding dimension of the protrusion 8, so that the entire outer shape of the artificial wood 1A or the wall portion of the bottom plate portion 4 and the like can be freely set. The effect of being easy to set is obtained.

  Further, since the artificial wood 1A only changes the projecting dimension of the protrusion 8 even if the dimension of the reinforcing member 3A to be inserted is changed, an effect that a significant change in the weight of the artificial wood 1A itself can be suppressed. can get.

  Moreover, since artificial wood 1A should just form the protrusion 8 supposing the dimension of the existing reinforcement member 3A, it is easy to use a commercially available steel material. That is, since the artificial wood 1A does not need to produce a dedicated reinforcing member 3A for the artificial wood 1A, the effect that it can be produced at low cost is obtained.

  Moreover, since the protrusion 8 is formed, the effect that the reinforcing member 3A can be effectively prevented from wobbling in the hollow portion 2 is obtained. Further, since the protrusion 8 is formed not on the bottom plate portion 4 but on the inner wall surface 6 s of the top plate portion 6, when the top plate portion 6 is located on the upper side and the bottom plate portion 4 is located on the lower side, It is possible to more effectively prevent the reinforcing member 3A from wobbling in the hollow portion 2.

  The reinforcing member 3A inserted into the hollow portion 2 is preferably fixed to the top plate portion 6 and / or the bottom plate portion 4 of the artificial wood 1A with a fixing tool P such as a bolt or a screw. Since the artificial wood 1A has protrusions 8 formed on the inner wall surface 6s of the top plate portion 6, when the reinforcing member 3A is fixed with the fixture P in the vicinity of the edge of the artificial wood 1A, the side surface of the artificial wood 1A The effect that it is easy to locate the fixed position visually is obtained. Moreover, it becomes easy also when a fixed position is demonstrated with a construction procedure, and the product cut | disconnected about 5-10 mm width can also be used as the positioning jig of a fixed position.

  Further, in the artificial wood 1A, the protrusion 8 is formed only in the central hollow portion 2, but it may be formed in each of the other hollow portion 2 into which the reinforcing member 3A is inserted. Further, it may be formed in all the hollow portions 2 into which the reinforcing member 3A can be inserted.

  Next, modifications of the artificial wood 1A will be described with reference to FIGS. Regarding the modified example, the same components as those in the above embodiment are indicated by the same reference numerals, the description thereof is omitted, and differences from the above embodiment are mainly described.

It is characterized by projecting in a direction opposite to each other.
Specifically, in the central hollow portion 2, the protrusions 8 extending continuously in one direction L are spaced apart from the inner wall surface 6 s of the top plate portion 6 and the inner wall surface 4 s of the bottom plate portion 4 facing each other. And is formed so as to protrude in a direction opposite to each other.

  Further, in the hollow portions 2 on both sides of the central hollow portion 2, the projections 8 are formed in the same manner as in the central hollow portion 2, and the standing plate portions 5 face each other. On the inner wall surfaces 5s and 5s, protrusions 8 extending continuously in one direction L are formed so as to protrude in a direction opposite to each other at intervals (in the rising direction).

The artificial wood 1B can exhibit the same functions, functions, and effects as the artificial wood 1A, and by adopting the above configuration, it is possible to further reduce the frictional resistance when the reinforcing member 3A is inserted. Therefore, the artificial wood 1B has an effect that the reinforcing member 3A can be easily inserted.
In addition, since the plurality of protrusions 8 are formed on each wall portion of the bottom plate portion 4, the top plate portion 6, and the standing plate portion 5, the effect that the protrusions 8 themselves can further reinforce the rigidity of the artificial wood 1B. Is obtained.

It is provided as follows. As a result, the protrusion 8b can prevent the reinforcing member 3C from swinging by positioning the end of the reinforcing member 3C between the standing plate part 5 and the protrusion 8.

That is, the artificial wood 1C of the modified example 2 adjusts the gap between the inner wall surface 4s and the reinforcing member 3C and restricts the movement of the reinforcing member 3C in the rotational direction (that is, from the standing plate portion 5 of the reinforcing member 3C). In order to prevent separation, projections 8a and 8b are provided.
With the above configuration, the artificial wood 1C has an effect that the reinforcing member 3C disposed along the partial inner wall surfaces 4s and 5s forming the hollow portion 2 can be easily inserted while being reliably positioned. can get.
