Claims (3)
- A fence comprising a plurality of posts (100) fixed to the ground and a plurality of crossbars (200) connecting and fixing the posts (100); The above-mentioned support (100) and crossbar (200) are formed into a natural wood shape through a mold (300), The above mold (300) is divided into an upper mold (310) and a lower mold (320), and an insert groove (330) capable of inserting a metal pipe or metal rod is formed in the center of the upper mold (310) and the lower mold (320), and a natural wood shape is realized on the inner surface of the insert groove (330), and a molding projection (340) and a projection groove (342) are formed on the outer side of the insert groove (330). A fence for marking a boundary or restricted access area, characterized by being configured such that when a metal pipe or metal rod with a diameter smaller than that of the insert groove (330) is inserted, the mold is closed and molding resin is injected to form a structure in which the molding resin fills the circumference of the metal pipe or metal rod and becomes integrated with the metal pipe or metal rod, thereby producing a support (100) or crossbar (200) that resembles a natural wood.
- In paragraph 1, The above-mentioned support (100) is integrally provided with a fixing plate (110) at the bottom, and the fixing plate (110) has a plurality of fastening holes (112) formed therein so that anchor bolts are inserted into the fastening holes (112) and then fixed to an object to be fixed on the ground; The above fixing plate (110) is configured such that a through hole (114) communicating with the inner diameter of the above support (100) is formed therethrough so that it can be inserted and fixed to a fixing rod provided on the ground; A fence indicating a boundary or restricted access area, characterized in that a first connecting joint (120) is fixed to the above-mentioned support post (100), a second connecting joint (220) is fixed to the above-mentioned crossbar (200), and the first and second connecting joints (120, 220) are hinged to each other so as to be configured to adjust the angle.
- In paragraph 1, The molding resin injected into the above mold (300) is composed of 50% by weight of polyester resin, 1% by weight of curing agent, and the remainder of additives; The above curing agent uses MEKP (Methyl Ethyl Ketone Peroxide); A fence marking a boundary or restricted access area, characterized in that the above additive is composed of 25% by weight of sand, 5% by weight of sawdust powder, 10% by weight of waste synthetic resin powder, 4% by weight of aluminum hydroxide, 4% by weight of magnesium hydroxide, and the remainder being PBAT (Poly-Butylene Adipate Terephthalate).
Description
A fence that marks a boundary or restricted area. The present invention relates to a fence marking a boundary or restricted access area, and more specifically, to an improved fence marking a boundary or restricted access area that not only ensures easy and convenient moldability and durability while having an eco-friendly wood texture and color, but also possesses excellent flame retardancy and water pressure resistance characteristics, enabling a long lifespan with high resistance to deterioration even when exposed to the external environment for a long period, and is equipped with fire-resistant properties based on its flame retardant characteristics. Fences are used to mark the boundary between roadways and sidewalks, or between sidewalks and parks, as well as restricted access areas (fences). The fence includes posts fixed to the ground at regular intervals and crossbars fixed across these posts. At this time, since the support must always be installed vertically on flat or sloping ground, it is installed by simply driving the lower part of the support into the ground or by inserting the lower part of the support into the ground to a certain depth and then pouring concrete around it to set up and fix the support stake. Meanwhile, posts and crossbars are typically installed using wood, but since wood rots and has low strength when used for a long time, steel is commonly used. Consequently, although preservative-treated lumber is sometimes used, it is expensive and difficult to maintain, so most have switched to steel except for specific demands. However, steel has the disadvantage of corroding, and because it is heavy, there is a high risk of safety accidents during installation work, and there is the disadvantage that a separate painting treatment must be applied to prevent corrosion. Moreover, since steel is an artificial material, it is not eco-friendly, and improvements in this regard are also required. In response to these requirements, a support and a crossbar having a texture and color resembling natural pine wood, as described in the [prior art literature] below, have been disclosed. However, the disclosed prior art has the disadvantage of being vulnerable to fire due to weak flame retardancy and having poor water pressure resistance, which leads to easy deterioration when exposed to the external environment for a long period, resulting in localized breakage and a shortened lifespan due to the occurrence of cracks. FIG. 1 is an exemplary perspective view of a fence according to the present invention. FIG. 2 is a bottom view of a support post constituting a fence according to the present invention. FIG. 3 is an exemplary diagram showing the connection structure between the posts and crossbars constituting the fence according to the present invention. FIG. 4 is an exemplary diagram showing a mold for manufacturing a fence according to the present invention. FIG. 5 is a drawing illustrating an example of mixing sand into a resin composition to implement a fence according to the present invention. Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings. As illustrated in FIG. 1, the fence according to the present invention includes a plurality of posts (100) fixed to the ground and a plurality of crossbars (200) connecting and fixing the posts (100). At this time, as shown in FIG. 2, the above-mentioned support (100) is integrally equipped with a fixing plate (110) at the bottom, and a plurality of fastening holes (112) are formed in the fixing plate (110), so that fixing stability can be secured by inserting an anchor bolt (not shown) into the fastening holes (112) and fixing it firmly to an object to be fixed on the ground in an anchor-like manner. In particular, the fixing plate (110) may be configured to have a through hole (114) formed through it that communicates with the inner diameter of the support (100), thereby allowing it to be inserted into and fixed to a fixing rod provided on the ground to further enhance fixing stability. On the other hand, while the crossbar (200) is generally fixed in a manner that is approximately orthogonal to the support (100), in addition to this, the crossbar (200) may be configured to allow for angle adjustment as shown in FIG. 3. According to FIG. 3, a first connecting joint (120) is fixed to the support (100), and a second connecting joint (220) is fixed to the crossbar (200), and the first and second connecting joints (120, 220) are hinged to each other so as to be able to adjust the angle. By doing this, the convenience of assembly during construction can be improved. In addition, the above-mentioned support (100) and crossbar (200) can be formed through a mold (300) of the shape shown in FIG. 4. That is, the above mold (300) is divided into an upper mold (310) and a lower mold (320), and an insert groove (330) is formed in the center of the upper mold (310) and the lowe
