Abstract

The present invention relates to a method for manufacturing a clamp for pipe fastening and a clamp manufactured thereby. Since the clamp body is manufactured by bending and forming a single steel plate, it reduces manufacturing costs and improves the durability of the parts. The present invention for realizing this is characterized by comprising: a punching step (ST 1) in which a pipe (40) is connected to one side and a fastener (30) is connected to the other side, wherein a steel plate of a certain thickness is processed to perform punching so that a curved portion (11) on which a pipe (40) can be mounted, a support portion (12) that supports the rear end of the cover (20), a wing portion (13) on which the curved portion (11) is formed, a first through hole (14) for connecting the cover (20), and a second through hole (15) for connecting the fastener (30) are each formed in a left-right symmetrical shape; a support portion bending step (ST 2) in which the two support portions (12) are bent into a right angle shape along a first bending line (a); and a wing portion bending step (ST 3) in which the two wing portions (13) are bent into a right angle shape along a second bending line (b).

Description

Method for manufacturing a clamp for pipe fastening and a clamp manufactured thereby The present invention relates to a method for manufacturing a clamp, and more specifically, to a method for manufacturing a pipe fastening clamp and a clamp manufactured thereby, which reduces the manufacturing cost of a clamp used in the installation process of construction scaffolding and improves ease of use at a construction site. Generally, after the building frame is erected, the exterior work is done first, followed by the interior work. To perform the exterior work, scaffolding is fixed to the outer part of the building and a safety net is installed so that the exterior walls of the building can be constructed. The scaffolding installed for the exterior wall construction of the aforementioned building has a truss structure composed of vertical, horizontal, or diagonal pipes, and the aforementioned clamps are provided at the connection or intersection parts of the aforementioned vertical, horizontal, or diagonal pipes to firmly connect them to each other. These scaffolding clamps are typically used by inserting the scaffolding into the clamp and tightening it with a bolt to secure the clamp inside the scaffolding. Meanwhile, conventional clamps had the problem of requiring excessive production time and cost during the manufacturing process. In particular, the clamp body was manufactured by welding three parts together, which made it difficult to produce and caused problems such as the welding parts falling off. In addition, when the cover is closed and the nut is tightened, the nut may loosen due to the load after fastening, potentially causing a safety accident. FIG. 1 is a perspective view of the exterior of a pipe clamp according to one embodiment of the present invention. FIG. 2 is a side view of the pipe clamp structure of the present invention. FIG. 3 is an unfolded view of the clamp body in the present invention. FIG. 4 is a diagram showing the state of the first bending section in the present invention. FIG. 5 is a diagram of the first bending state process in the present invention. FIG. 6 is a diagram showing the secondary bending section in the present invention. FIG. 7 is a diagram of the secondary bending state process in the present invention. FIG. 8 is a detailed structural diagram of the rear end of the clamp body in the present invention. FIG. 9 is a planar structural diagram of the clamp body in the present invention. FIG. 10 is an enlarged view of section A of FIG. 4 according to another embodiment of the present invention. FIG. 11 is a detailed view of the assembly state of part B of FIG. 8 according to another embodiment of the present invention. Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the attached drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art. Accordingly, the shapes of components depicted in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that identical components in each drawing may be illustrated with the same reference numeral. Furthermore, detailed descriptions of functions and configurations of known technology that are deemed to unnecessarily obscure the essence of the invention may be omitted. First, the manufacturing process of a pipe fastening clamp according to one embodiment of the present invention is as follows, as illustrated in FIGS. 1 to 9. In the present invention, a clamp body (10) is manufactured in which a cover (20) is connected to one side and a fastener (30) is connected to the other side. <Punching Stage>(ST 1) First, in the punching step, a steel plate of a certain thickness is processed to form a curved portion (11) on which a pipe (40) can be mounted, a support portion (12) that supports the rear end of the cover (20), a wing portion (13) on which the curved portion (11) is formed, a first through hole (14) for connecting the cover hinge (21) of the cover (20) so that it can be rotated, and a second through hole (15) for connecting the fastener hinge (31) of the fastener (30) so that it can be rotated, each in a left-right symmetrical shape. That is, at this time, punching is performed in the shape as shown in FIG. 3, and in particular, an uneven surface (12a) is formed on the mutually opposing parts of the two support parts (12), so that when the two uneven surfaces (12a) are bent as shown in FIG. 7 and FIG. 8 during the subsequent support part bending step (ST 2), the two uneven surfaces (12a) engage with each other, thereby performing a twist prevention function. In addition, it can be seen that a support protrusion (16) capable of supporting the bent support part (12) from below is formed
