Abstract

The present invention relates to a vinyl greenhouse pipe fastening device equipped with reinforcing protrusions (also called a pipe fastening fixing clamp or a plate clamp). The pipe fastening device of the present invention is for fastening and fixing a first pipe (1) and a second pipe (2) arranged to intersect, and is made of a steel wire of an elastic metal material, wherein a first curved portion (11) is formed by bending the central part of the steel wire in a rounded shape, and the first pipe (1) is fitted into the first curved portion (11); and a second curved portion (12) is formed by extending both sides of the steel wire forming the first curved portion (11) at an angle in the length direction of the first pipe (1), with the middle part bent in a rounded shape in a direction perpendicular to the bending direction of the first curved portion (11), and the second pipe (2) is fitted into the second curved portion (12); and a third curved portion (13) is formed by extending the steel wire forming the second curved portion (12) at an angle in the length direction of the first pipe (1) and bending in the opposite direction to the second curved portion (12). A steel wire assembly (10) and; A body part (20c) is formed, which is made of a metal plate having elasticity of a certain length and is installed spaced apart from the first pipe (1) while being aligned with the length direction of the first pipe (1); a one-sided bent part (20a) is formed on one side of the body part (20c) located on the side of the first curved part (11) and is bent at a certain angle toward the first pipe (1), so that the end of the one-sided bent part (20a) is closely supported on the outer surface of one side of the first pipe (1); and a other-sided bent part (20b) is formed on the other side of the body part (20c) located on the side of the third curved part (13) and is bent toward the first pipe (1), so that the end of the other-sided bent part (20b) is closely supported on the outer surface of the other side of the first pipe (1), and the third curved part (13) is fitted and supported on both sides of the other-sided bent part (20b). A pipe fastening device comprising a steel plate assembly (20) having wing portions (20e) formed with support grooves (20d) on both sides, wherein on the surface of the steel plate assembly (20), before the bending process of the one-sided bend portion (20a) and the other-sided bend portion (20b), the outer surface is pressed inwardly along the longitudinal direction of the steel plate with a certain width, thereby forming a first reinforcing projection (21) that forms a straight line extending across the one-sided bend portion (20a), the body portion (20c), and the other-sided bend portion (20b) on the inner surface, protruding parallel to both sides, and the outer surface at the point where the other-sided bend portion (20b) and the body portion (20c) meet is pressed inwardly, thereby forming a second reinforcing projection (22) on the inner surface. The present invention provides a pipe fastening device capable of preventing damage to facilities from strong winds and heavy snow. In particular, a pipe fastening device is provided that has the same shape as a commercially available product, allowing it to be used in combination with commercially available products, and can be used simply by processing commercially available products. In particular, when separating a steel plate assembly and a steel wire assembly using a tool penetration hole, a person who does not know the method of use may forcibly pull the steel wire without pushing or pulling it with a tool. In this case, the structure disclosed in Patent Documents 3 and 4 may cause the bent portion to bend and deform. However, in the present invention, since the first reinforcing projection and the second reinforcing projection are provided, bending deformation of the bent portion does not occur even when forcibly pulled, thereby enabling workers other than skilled workers to easily perform construction of vinyl greenhouse facilities.

Description

Vinyl greenhouse pipe fastening apparatus with reinforcing bump The present invention relates to a pipe fastening device for the frame of facilities such as vinyl greenhouses, and more specifically, to a vinyl greenhouse pipe fastening device equipped with reinforcing protrusions that allows for easy fastening and fixing of intersecting pipes, as well as preventing deformation of the steel plate assembly to prevent damage to the facility and thereby enhancing structural stability. Generally, when installing structures using pipes, vertical pipes acting as columns and horizontal pipes acting as beams are fixed together. At this time, as a means of mutually fixing the cross-arranged horizontal and vertical pipes, in the case of structures where relatively light weight is applied, such as crop shading facilities, a method of tying with ropes was used, and in the case of structures where heavy weight is applied, such as temporary structures at construction sites, the cross-arranged pipes were fastened and fixed using a fastener called a 'clamp'. However, in the case of the method of securing intersecting pipes by tying them with a rope, there was a problem in that not only was a lot of force required to pull the rope taut and wind it to ensure the connection strength between the pipes, but the strength was also significantly reduced when the rope came loose due to external factors. Furthermore, while the method of mutually connecting and securing intersecting pipes using clamps offers the advantage of achieving very high strength, it generally has the disadvantage that tightening and turning bolts and nuts requires significant effort and time. Additionally, when exposed outdoors for extended periods in the connected state, the bolts and nuts often corrode, making disassembly difficult. Technologies to resolve these problems include "steel plate clamp for greenhouses" (Korean Registered Patent Publication No. 10-0882454, Patent Document 1) and "steel wire clamp structure for fixing and supporting pipes for vinyl greenhouses" (Korean Published Patent Publication No. 10-2022-0168267, Patent Document 2). In addition, the applicant of the present invention has also filed and registered "pipe fastening device" (Korean Registered Patent Publication No. 10-0883391, Patent Document 3) and "pipe fastening device for vinyl greenhouses" (Korean Registered Patent Publication No. 10-1462626, Patent Document 4). The aforementioned technologies are basically characterized by the ability to fix intersecting pipes by utilizing the elasticity of steel wire to easily fasten them without bolts or nuts. In addition, the elasticity of the steel wire allows for easy disassembly, making it very convenient to assemble facilities with intersecting pipe structures, such as vinyl greenhouses. However, as the intensity of heavy snowfall and strong winds has recently increased rapidly compared to the past, steel wire assemblies or steel plate assemblies are deforming due to strong winds or loads, leading to facility damage; consequently, there is a growing need to upgrade existing products to address this issue.

FIG. 2 is a perspective view of the fastening device of the present invention in the other direction. FIG. 3 is a perspective view showing the state in which the first reinforcing projection is extended and formed on one side bent portion and the other side bent portion in the present invention. FIG. 4 is a perspective view showing an example in which a reinforcing support member is formed on the outer edge of a one-sided bent portion in the present invention. FIG. 5 is a perspective view showing an example of separating a steel plate assembly using a tool in the present invention and the separated steel plate assembly. The vinyl greenhouse pipe fastening device equipped with reinforcing protrusions of the present invention inherits the configuration of the pipe fastening device disclosed in Patent Documents 3 and 4, which were previously filed and registered by the applicant of the present invention as described above. More specifically, the pipe fastening device of the present invention is for fastening and fixing a first pipe (1) and a second pipe (2) arranged to intersect, and is composed of a steel wire assembly (10) in which steel wire is processed and a steel plate assembly (20) in which steel plate is processed. The above steel wire assembly (10) is referred to as a 'steel wire clamp' and the steel plate assembly (20) as a 'steel plate clamp' in the market, but for convenience of understanding, the terms used in Patent Documents 3 and 4 are adopted in this invention. The steel wire assembly (10) is made of a steel wire made of an elastic metal material, and as shown in FIGS. 1 and 2, a first curved portion (11) is formed by bending the central part of the steel wire into a
