Description

[Technical field]

[0001] This invention relates to a wooden fence used for ordinary housing, etc. [Background technology]

[0002] Traditionally, fences have been built around houses and sites to divide areas, provide privacy, and prevent intrusion, and block walls, wooden board walls, brick walls, etc. are widely and commonly used. Block walls are heavy but dreary, and there is a risk of them collapsing in the event of an earthquake, etc. Wooden board walls have a distinctive appearance with a distinctive wood grain and texture, but they are not very durable and are susceptible to decay, insect damage, and sunburn.

[0003] In recent years, for example, materials for wooden fences have been sold that have a texture similar to natural wood, as well as high weather resistance and strength, by mixing wood powder with polyethylene resin and coating the surface with high-density polyethylene resin to create a multi-layer synthetic wood material (see, for example, non-patent document 1).

[0004] Furthermore, in order to alleviate the sagging and distortion of wooden fences caused by expansion and contraction due to temperature, a drawback of resin materials, materials for wooden fences that use a metal material (such as aluminum) with sufficient strength as the core material to prevent expansion and contraction due to temperature are also sold (for example, see Non-Patent Document 1).

[0005] Furthermore, aluminum building material panels covered with a highly weather-resistant wrapping sheet are also known, which can be used for a wide range of purposes, such as renovating old block walls, fences, and ceilings (see, for example, Non-Patent Document 2).

[Searched on September 22, 2024], Internet<URL:https: / / proex.takasho.jp / eab / > Summary of the Invention [Problem to be solved by the invention]

[0007] However, when installing a wooden fence using the above-mentioned board-shaped fence materials (boards), each board needs to be aligned with the corresponding post, screwed in place, and many other parts such as caps need to be attached, which requires a considerable amount of work and multiple workers on site.

[0008] In addition, the work of digging up the ground, digging holes, erecting posts and pouring mortar takes time and effort, and conventional board materials are relatively weak. This means that the pitch (spacing) between adjacent posts must be narrow, for example 1000 mm, which requires digging a considerable number of holes, and this creates the problem of labor-intensive on-site construction work.

[0009] Furthermore, if the material used for the boards in a wooden fence is prone to absorbing moisture, stains, water stains, dirt, and the like will easily occur, making it difficult to maintain the beautiful appearance of the wooden fence over a long period of time.

[0010] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a wooden fence that simplifies construction work by reducing the number of posts that need to be installed when setting up a wooden fence, and that can maintain a beautiful appearance without bending or distortion for a longer period of time. [Means for solving the problem]

[0011] In order to achieve the above-mentioned object, the present invention provides a wooden fence comprising a number of posts extending vertically, and plate members attached horizontally perpendicular to one side of the posts and arranged in multiple rows at predetermined intervals in the vertical direction, wherein at least one row of the plate members arranged in the multiple rows is a first plate member using a metal material as its core material.

[0012] In this board fence, the uppermost and lowermost boards among the multiple rows of boards arranged side by side are the first boards which use an aluminum core material as their core material, and it is preferable that high-density polyethylene is used for the surface layer covering the aluminum core material of the first boards.

[0013] This board fence further includes a second board material whose surface material is made of high-density polyethylene and whose core material is made of high-density polyethylene resin and wood powder, and it is preferable that the board materials other than the first board material among the boards arranged in the multiple rows are constructed from the second board material.

[0014] In this wooden fence, it is preferable that the pitch between adjacent posts is 2000 mm, and the dimensions of the boards are 145 mm in width, 1995 mm in length in the longitudinal direction, and 22 mm in height.

[0015] This wooden fence further comprises a reinforcing material which has a plate shape including a hollow structure inside and into which an aluminum square pipe can be removably inserted, and which is preferably fixed with screws along the vertical direction to the back side of the plate. Effect of the Invention

[0016] The wooden fence according to the present invention comprises multiple vertically extending posts and multiple rows of plate materials attached to one side of the posts in a horizontal direction perpendicular to the surface of the posts and arranged side by side at a predetermined interval from each other in the vertical direction, with at least one row of the multiple rows of plate materials being a first plate material using a metal material as its core material 3ab. With this configuration, the wooden fence according to the present invention can reduce the number of posts to be installed when setting up the wooden fence, simplifying the construction work and allowing the fence to maintain a beautiful appearance without bending or distortion for a long period of time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] (Embodiment) A wooden fence (also called a resin fence or a wooden fence) according to an embodiment of the present invention will be described with reference to the drawings. First, the structure of the wooden fence according to this embodiment will be described with reference to Figs. 1 to 3. This wooden fence 1 becomes a continuous wooden fence by fixing a board material (a board fence material) to the front of a post erected from the ground or the like. A wooden fence is an enclosure installed at the boundary between a house, a site, etc. and something else, and is installed for the purposes of dividing the area, hiding the area, and preventing intrusion.

[0019] As shown in Figs. 1 and 2, a wooden fence 1 comprises a plurality of posts 2 erected vertically from the ground (GL) and a plurality of boards 3.

[0020] The support pillar 2 is fixed vertically by pouring mortar 2b into a pilot hole 2a dug in the ground, and is an aluminum square pipe pillar of, for example, 60 mm x 60 mm.

[0021] The left and right ends of the plate materials 3 are attached using screws 3a (machine screws) or the like in a horizontal direction perpendicular to one face of the support post 2, and the plate materials 3 are arranged in multiple rows at a predetermined interval from each other in the vertical direction. At least one of the left and right ends of the plate materials 3 may be formed with pilot holes for inserting screws to fix the plate materials 3 to the support post 2. Each plate material 3 has, for example, a width of H145mm, a longitudinal length of W1995mm, and a height of D22mm, and multiple plate materials 3 are arranged in parallel with a gap of 5mm between each other above and below. It is preferable that the size of the plate materials 3 is close to the dimensions of general wooden fence lumber.

[0022] During actual construction, end caps (e.g., 1.5 mm thick, not shown) of the same color are attached to the left and right ends of the plate material 3 so as to hide the core material inside the plate material 3. The interval between adjacent plate materials 3 in the left-right direction is set to 2 mm, thereby achieving a pitch of 2000 mm between the posts 2 (i.e., 1995+1.5+2+1.5=2000 mm).

[0023] Next, the structures of the first plate 3a and the second plate 3b, which are the two types of plate 3 used in the board fence 1 according to this embodiment, will be described with reference to Figs.

[0024] As shown in Figure 4, the first board material 3a uses a surface layer 3aa of high density polyethylene resin (HDPE) with a thickness of, for example, 0.5 mm to achieve an appearance similar to a natural wood-grain fence, while the core material 3ab uses aluminum material (metal material) with a thickness of, for example, 1.2 mm, which has sufficient strength, to reduce the bending and distortion of the board fence caused by expansion and contraction due to temperature, which is a drawback of resin materials. The surface layer material 3aa and the core material 3ab are bonded together via an adhesive layer 3ac with a thickness of, for example, 0.3 mm.

[0025] In this way, not using wood powder for the surface layer 3aa of the first board 3a prevents moisture absorption, and as a result, the occurrence of stains, water stains, dirt, etc. can be suppressed compared to conventional products. Furthermore, by using an aluminum core material 3ab along the longitudinal direction inside the first board 3a, not only does it increase strength, but it also hardly expands or contracts due to temperature, and the stability of the material can be maintained for a long period of time. As a result, when the first board 3a is used for a wooden fence 1, it is not necessary to take measures such as leaving a gap at the butt joint of the first board 3a and covering it with a connecting cover board to take expansion and contraction into consideration.

[0026] As shown in Figure 5, the second board 3b uses, for example, high density polyethylene resin (HDPE) as the surface layer 3ba, achieving an appearance similar to a natural wood-grain fence, while the core material 3bb uses high density polyethylene resin (HDPE) and wood powder. This core material 3bb does not have the same strength as the first board 3a, but because it is not an aluminum core material, the price can be kept to about two-thirds that of the first board 3a, which has the advantage of making it possible to economically install the board fence 1. Other effects and sizes are the same as those of the first board 3a.

[0027] As shown in Fig. 2, for the boards 3 constituting the wooden fence 1, at least one row of the boards 3 arranged side by side in a plurality of rows uses the first board 3a having a metal material with sufficient strength as its core material. Specifically, the first board 3a is used for the top and bottom rows of the boards 3 arranged side by side in a plurality of rows, and the second board 3b is used for the rest. In a conventional wooden fence 1 using only the second board 3b made of resin and wood powder, the second board 3b is not strong enough and is easily bent, so the maximum pitch of the posts 2 is 1000 mm. On the other hand, in the wooden fence 1 according to the present embodiment, the pitch of the posts 2 can be set to 2000 mm by using the first board 3a with high strength, and as a result, the number of posts 2, the number of pilot holes 2a, and the work of pouring mortar 2b can be halved, and the work during construction can be significantly reduced.

[0028] The size of the wooden fence 1 can be adjusted in various ways. When the fence has nine boards 3 as shown in FIG. 3, the dimensions are W2000mm, H1400mm, and D22mm, and when the fence has six boards 3, the dimensions are W2000mm, H900mm, and D22mm.

[0029] As shown in Fig. 6, a reinforcing member 4 may be provided, which has a plate shape with a hollow structure 4a inside and into which an aluminum square pipe can be detachably inserted. As shown in Fig. 3, the reinforcing member 4 is fixed with screws in the vertical direction to the rear side of the plate materials 3a and 3b in order to improve the strength of the plate materials 3a and 3b.

[0030] Next, a description will be given of the process for erecting the wooden fence 1. Here, a description will be given of the process for erecting the wooden fence 1, which is 1400 mm above ground and has a pitch of 2000 mm between adjacent posts 2.

[0031] First, pilot holes 2a are dug on the ground side, and mortar 2b is poured into the pilot holes 2a while the posts 2 are erected from the ground surface GL at predetermined intervals (2000 mm intervals in this figure).

[0032] Next, the first plate material 3a is attached to the top and bottom of the erected support 2. At this time, the first plate material 3a is temporarily fixed to the support 2 in the horizontal direction using screws 3c at both the left and right ends of the first plate material 3a. At this time, since the first plate material 3a has an aluminum core material 3ab and is strong, even when the column pitch is 2000 mm, the first plate material 3a does not bend midway, and the horizontality of the first plate material 3a, the alignment of the support 2, the verticality of the support 2, etc. can be easily visually confirmed. However, when the second plate material 3b is used and the pitch of the support 2 is 2000 mm, the second plate material 3b bends midway, and the horizontality of the second plate material 3b, the alignment of the support 2, etc. cannot be accurately visually confirmed.

[0033] 1 and 2, a mark (line 5) is made at the position where the lowest board is to be fixed on the lower end of the support 2. The lower board of the lowest first board material 3a serves as an effective jig for adjusting the horizontal level.

[0034] Next, once the mortar 2b has hardened, the left and right ends of the second plate material 3b, which is arranged in parallel between the top and bottom first plate materials 3a, are similarly fixed with screws. At this time, in order to maintain a specified gap distance between the plate materials 3 (5 mm in this figure), spacers with 5 mm intervals may be inserted between the plate materials 3. The spacers are rectangular parallelepiped components that are used to position the gaps between the plate materials 3 when the screws 3c are installed, and are removed after the plate materials 3 are fixed.

[0035] A dedicated drilling jig can be used on-site to pre-drill holes on the left and right ends of the plate material 3. There is no need to measure the hole positions while drilling each sheet, and it is sufficient to insert the screws 3c into each pilot hole and drive the screws 3c through to the support 2. This makes it extremely easy to fasten the plate materials 3a and 3b to the support 2.

[0036] Finally, the reinforcing material 4 is fixed with screws on the back side of the board 3 at the horizontal midpoint of the board 3 (the midpoint between adjacent posts 2) in the direction extending vertically, completing the installation of the board fence 1. Figure 3 is a perspective view of the board fence 1 after installation is completed, and it can be seen that the two board fences 1 are continuous as one unit.

[0037] As described above, the wooden fence 1 according to the present embodiment includes multiple vertically extending posts 2 and plate materials 3 that are attached to one surface of the posts 2 in a horizontal direction perpendicular to the horizontal direction and are arranged in a plurality of rows at a predetermined interval from each other in the vertical direction. At least one of the rows of plate materials 3 arranged in parallel is a first plate material 3a using a metal material as its core material 3ab. Furthermore, the top and bottom rows of the rows of plate materials 3 arranged in parallel are first plate materials 3a using aluminum material as its core material, and high-density polyethylene that does not easily absorb moisture is used for the surface layer material 3aa of the first plate material 3a. Furthermore, high-density polyethylene is used for the surface layer material 3ba, and high-density polyethylene resin and wood powder are used for the core material 3bb. Among the rows of plate materials 3 arranged in parallel, the plates 3 other than the first plate material 3a are composed of the second plate material 3b. With this configuration, the first plate material 3a has rigidity due to the aluminum core material 3ab, and moisture absorption can be prevented by using high-density polyethylene for the surface layer material 3aa. As a result, the number of posts 2 that need to be installed when erecting the wooden fence 1 can be reduced, simplifying the construction work, and a beautiful appearance without sagging or distortion can be maintained for a longer period of time.

[0038] Furthermore, in the market for wooden fences 1 (resin fences), the ease of installation and quality can be improved while maintaining the sophisticated design and weather resistance of the board material 3. Furthermore, since the board material 3 can be directly fixed to the posts 2 using screws 3c, and the pitch of the posts 2 is 2000 mm, twice that of conventional products, a cheaper wooden fence 1 product can be provided to the market.

[0039] The present invention is not limited to the configuration of the above embodiment, and various modifications are possible without changing the spirit of the invention. For example, the size of the wooden fence 1 is not limited to the above, and can be adjusted as appropriate according to the user's application. Furthermore, the arrangement of the first boards 3a used in the wooden fence 1 is not limited to the top and bottom rows, and can be adjusted as appropriate according to the conditions of the installation site, such as the top row only. Spacers of 5, 10, 15, and 20 mm are also available to maintain the gap distance. [Explanation of symbols]
