Description

[Technical Field]

[0001] The present invention relates to a fence. [Background technology]

[0002] Concrete block walls (hereafter referred to simply as "block walls") are commonly used as walls, but simply fixing them with mortar or other adhesives makes them prone to collapse in earthquakes and other disasters, making them dangerous. Therefore, in Japan, it is mandatory to use reinforcing bars that meet JIS standards, arranged horizontally and vertically at specified intervals. Furthermore, as the height of the fence increases, it becomes necessary to install retaining walls.

[0003] In other words, each concrete block weighs more than 10 kg, and if it collapses and you are crushed underneath it, it could be fatal. However, as the wall ages, even if it meets the above standards, the reinforcing bars may rust and the wall may no longer be able to maintain its required strength, or the blocks themselves may crack, putting the wall at risk of collapse in an earthquake.

[0004] Therefore, the inventor of the present invention has already proposed a fence that comprises a fence main body and support legs that support the fence main body and are arranged intermittently in the horizontal direction of the fence main body, the fence main body comprising a frame-shaped core made of a lightweight metal material having at least a rectangular frame shape, a foamed resin part made of a foamed resin plate that surrounds the side periphery of the frame-shaped core, and a decorative part made of a decorative plate that covers the surface of the foamed resin part, the support legs being almost completely embedded in a concrete foundation that rises from the ground, and the lower end of the decorative plate, which is adhesively fixed to the surface of the foamed resin part, is arranged to cover the surface of the concrete foundation (see Patent Document 1).

[0005] In other words, this wall structure reduces the overall weight of the wall compared to conventional block masonry. Therefore, even if it collapses in an earthquake and hits a passerby, the degree of injury will be minimized. It can be made easier.

[0006] In addition, there is no need to place reinforcement at high positions as with conventional block masonry, making it easier to install. The foam resin part is made of foam resin board, so it is easy to adjust the height and width on site. Moreover, foam resin boards are available in a variety of thicknesses, making it easy to use commercially available ones. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent No. 6934845 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in the case of the fence structure of Patent Document 1, a composite board (for example, Takasho Corporation, product name Ever Art Board) was used, in which a resin core material was sandwiched between plates made of aluminum or aluminum alloy as a decorative layer to protect the resin foam layer.While this has the advantages of being strong enough to protect the resin foam layer and having excellent design potential, such composite boards have the problem that, unlike foam resin boards, it is difficult to easily make fine adjustments to dimensions or shape on site using hand tools such as cutters and scissors.

[0009] In view of the above circumstances, the present invention has an object to provide a lightweight fence that is easy to install, allowing for fine adjustments during on-site construction. [Means for solving the problem]

[0010] In order to achieve the above object, the fence of the present invention has a fence body, which has a framework, a foamed resin layer surrounding the framework, and a protective coating layer laminated on the outside of the foamed resin layer to protect the foamed resin layer, and is characterized in that the protective coating layer is easily cuttable. In the present invention, "easily cuttable" means that the material can be easily cut using hand tools such as a cutter or scissors.

[0011] The wall of the present invention is not particularly limited, but may be one in which the foamed resin plate and the easily cuttable material that constitutes the protective covering layer are integrated in advance. In other words, by laminating a layer of easily cuttable material onto the surface of the foamed resin board in advance at the factory, the protective coating layer can be formed accurately, and there is no need to cut and adjust it separately during on-site construction, which reduces the time required to adjust the length and width on-site.

[0012] In the wall of the present invention, the easily cuttable material is not particularly limited as long as it can be easily cut using hand tools such as a cutter or scissors. Examples include plastic thin films, wood thin films, inorganic material thin films, wallpaper materials, and composite materials thereof, which may be used alone or in combination. Furthermore, if the protective coating layer has insufficient functions to be complemented, such as lack of design, poor waterproofing, or insufficient strength, a paint layer that can complement each function may be provided after construction.

[0013] The fence of the present invention is not particularly limited, but the framework can be assembled by screwing, gluing, fusing, or the like using framework materials made of, for example, lightweight metal, fiber-reinforced plastic reinforced with carbon fiber, cellulose fiber, or the like, engineering plastic, wood material, inorganic material, or plate, rod, or tube material made from a composite material of these.

[0014] The framework may be constructed by assembling vertical and horizontal members made of plate, tubular or rod materials into a frame shape, and braces may be inserted within the frame. In particular, if a fiber-reinforced plastic cylinder is used as the frame material, it will be lightweight and have excellent strength. Also, if thinned wood or bamboo is used as the wood material, it will be possible to make effective use of the thinned wood or bamboo and reduce costs.

[0015] The fence of the present invention may be provided with support legs extending downward from the fence body. The lower ends of the vertical members may double as the support legs, or the support legs may be attached separately to the lower ends of the framework, but it is preferable for part of the vertical members to double as the support legs. That is, the support legs can be formed at the same time as the framework is produced, which improves workability. The support legs may be arranged at equal intervals, but the intervals may be varied depending on the condition of the construction surface of the wall construction site.

[0016] The foamed resin layer is not particularly limited, but can be obtained, for example, by a method in which a foamed resin plate is fixed to a framework while surrounding the framework using metal fittings, adhesive, double-sided adhesive tape, or the like, or by a method in which the framework is first prepared, then placed in a foam molding mold, and a foamed resin composition is filled and foamed into the foam molding mold. The resin for forming the foamed resin layer is not particularly limited, but examples thereof include polystyrene, polyethylene, and polypropylene. As the foamed resin plate for forming the foamed resin layer, a general-purpose EPS (expanded polystyrene by beads method) plate that can be easily obtained at a home improvement store or the like may be used.

[0017] The fence of the present invention may have, but is not particularly limited to, at least one through-hole penetrating through the fence in the thickness direction, and the inner peripheral surface of the through-hole may be watertightly coated. Methods for covering the inner peripheral surface of the through hole watertight include fitting a plastic or metal cylindrical body into the through hole, or fitting a glass or transparent resin block into the through hole. The above-mentioned structure enhances the design of the fence. Furthermore, when the blocks are not fitted together, they act as a wind vent, preventing damage to the fence from the wind.

[0018] The fence of the present invention preferably has a hollow portion formed inside the framework that is not filled with a foamed resin material or the like. In other words, by providing a hollow section, it becomes easier to wire electrical equipment such as intercoms and lighting fixtures when attaching them to the fence.

[0019] In the fence of the present invention, the foamed resin layer or protective coating layer may be formed by connecting foamed resin plates that form the foamed resin layer or protective coating layer, or plates or sheets that form the protective coating layer, in at least one of the horizontal and vertical directions. They may also be connected via a trim. [Effects of the Invention]

[0020] The fence of the present invention has a fence body that has a framework, a foamed resin layer surrounding the framework, and a protective covering layer laminated on the outside of the foamed resin layer to protect the foamed resin layer, and because the protective covering layer is easily cuttable, it has the following excellent effects.

[0021] That is, since the middle layer is made of foamed resin, the overall weight of the wall is lighter than that of conventional block masonry, so that even if the wall collapses in an earthquake or the like and hits passersby, the degree of injury can be reduced. Furthermore, since the protective coating layer is easily cuttable, it can be easily cut together with the foamed resin portion, making it easy to adjust the height and narrow the width on-site.

[Figure 3] FIG. 3 is an enlarged view of a portion Y in FIG. 2. [Figure 4] FIG. 2 is an enlarged end view of the wall of FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a fence according to the present invention will be described in detail with reference to the drawings. 1 to 4 show a first embodiment of a fence according to the present invention.

[0024] As shown in FIG. 1, one end of this fence 1 is in contact with a gatepost 2, and as shown in FIG. 2, the fence 1 comprises a fence body 3 and a support leg 56. As shown in FIG. 2, the fence body 3 includes a framework 5, a foamed resin layer 6, a protective covering layer 7, and a coping 8.

[0025] The framework 5 is formed by assembling vertical members 51 and horizontal members 52, each of which is a cylindrical body made of carbon fiber reinforced plastic, into a frame shape via L-shaped metal fittings 53, fixing bolts 54, and fixing plates 55. The vertical members 51 are arranged at equal intervals in the horizontal direction of the fence, and the lower ends of at least some of the vertical members 51 also serve as support legs 56, as shown in Figure 2. In other words, the vertical members 51 equipped with support legs 56 are longer than the other vertical members 51 by the length of the support legs 56.

[0026] Although not shown, the horizontal members 52 are hung in parallel between the vertical members 51 in the vertical direction, three at a time, as shown in Figures 2 to 4, and their ends are fixed to the vertical members 51 via L-shaped metal fittings 53, fixing bolts 54, and fixing plates 55. That is, the framework 5 is formed into a frame shape by vertical members 51 and horizontal members 52 with a gap S inside.

[0027] The foamed resin layer 6 and the protective covering layer 7 are formed by arranging the side surface laminated plates 4 a and the end surface laminated plates 4 b so as to surround the framework 5 . That is, the side surface laminate 4a and the end surface laminate 4b are formed by laminating a multilayer film that is easy to cut using hand tools such as a cutter or scissors, which has a metal thin film layer between transparent resin films, which serves as the protective coating layer 7, on one side of a foamed resin plate such as EPS that forms the foamed resin layer 6.

[0028] As shown in FIG. 3, the side surface laminate 4a and the end surface laminate 4b are restricted in their vertical movement by support fittings 41 fixed with screws to the upper cross member 52 and the lower cross member 52 (not shown in FIG. 3), and the corners are covered with L-shaped corner cover materials 42 as shown in FIG. 4.

[0029] In Figures 2 and 3, 63 is a spacer made of foamed resin that fills the gap S between the vertical member 51 and the side laminate 4a, and is fixed in advance to a predetermined position on the vertical member 51 with adhesive or double-sided tape. A parting material 73 is provided at the joint between the side surface laminate plates 4a.

[0030] As shown in FIGS. 1, 2 and 3, the coping 8 is fixed to the cross member 52 at the upper end with screws. The support legs 56 are supported and fixed to a concrete foundation 9 buried in the ground G.

[0031] In addition, in Figures 1 and 2, 16 is a through hole and 17 is a line light.

[0032] As mentioned above, this fence 1 has protective covering layer 7 that protects foamed resin layer 6, which can be easily cut using hand tools such as cutters or scissors. This allows for cutting along with foamed resin layer 6 at desired locations on-site, allowing for on-site construction to be tailored to fit the dimensions. Furthermore, it is lighter than a block wall, and there is no risk of serious injury to passersby if it were to collapse. It is also easy to remove, allowing for quick restoration.

[0033] The present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the foam resin plate and the material layer that will become the protective coating layer are laminated in advance, but they may be laminated on-site by spraying or pasting. In the above embodiment, the fence is equipped with through holes and line lights, but these may be omitted, and other electrical devices such as an intercom or a motion sensor and lights that are activated by the motion sensor may be attached instead.

[0034] In the above embodiment, the support legs are supported by a concrete foundation buried in the ground, but the support legs may also be fixed by inserting them into holes in one or two layers of concrete blocks that serve as the foundation laid on the ground and pouring concrete into the holes. In the above embodiment, the vertical members and horizontal members are fastened together with screws, but they may also be fixed together in advance at the factory by adhesive or welding.

[0035] In the above embodiment, the side laminated plate is a flat plate, but to enhance the design of the wall surface of the fence, it may be curved or have an uneven shape with uneven portions at least in part. Furthermore, instead of both surfaces of the wall being curved or uneven, only one surface may be curved or uneven.

[0036] In the above embodiment, the foamed resin portion is formed of an EPS plate, but it may be formed of other foamed resin materials such as foamed polyethylene. [Explanation of symbols]
