However, in the case of the welding method, there is a problem in that the mechanical properties of the base material are changed due to the heat of welding or the safety is deteriorated for reasons such as welding impossible or poor welding occurs in the case of a complicated shape. In particular, in the case of different materials, it is very difficult to combine them by welding, and even if possible, there is a problem in that the production cost is excessively generated.

In addition, in the welding bonding method, there is a disadvantage in that the labor cost burden is large in the case of manual welding, and in the case of automatic welding, the initial investment cost burden is large and it is difficult to apply to complex shapes.

On the other hand, in the case of the rivet coupling method, there is a problem in that the use is limited depending on the size of the target object, it is difficult to apply to a structure with a large load, and when the rivet connection part is damaged by external force and corrosion, there is a problem that safety is greatly reduced.

In addition, although the bolt/nut coupling method is the most widely used method in the industrial field, it is not desirable to apply it to scaffolding components requiring safety because it can be easily loosened.

In particular, the system scaffold 1000 according to an embodiment of the present invention is a new coupling means when manufacturing the vertical member 200, the horizontal member 300, the brace member 400, the workbench 500, etc. It is characterized in that the safety and work convenience of the system scaffold 1000 are remarkably improved by combining the parts using the assemblies 100 and 100a.

Hereinafter, the structure of each component of the system scaffold 1000 according to an embodiment of the present invention will be described in detail.

1. Fixing pin assembly (100, 100a)

The fixing pin assemblies 100 and 100a according to an embodiment of the present invention are component coupling means used when manufacturing the vertical member 200 , the horizontal member 300 , the brace member 400 , the work table 500 , and the like.

First, the fixing pin assembly 100 according to the first embodiment of the present invention is a female member 110 having a coupling groove 115 as shown in the exploded perspective, exploded cross-sectional and coupling cross-sectional views of FIGS. 2 to 4 . and a male member 130 having a coupling protrusion 135 inserted into the coupling groove 115 of the female member 110 .

In the fixing pin assembly 100 according to the first embodiment of the present invention, the female member 110 and the male member 130 are coupled by an interference fit, and thus conventional coupling methods such as welding, rivets, bolts/nuts, etc. A number of problems can be solved.

The female member 110 includes a body 111, a coupling groove 115 formed at one end of the body 111, and a first flange formed at the other end of the body 111 and having a larger diameter than the body 111 ( 113).

A plurality of fingers 118 are formed around the coupling groove 115 , and a cutout 119 is formed between the adjacent fingers 118 in the longitudinal direction from the end.

In this way, when the cutout 119 is formed between the fingers 118, elastic deformation of each finger 118 is possible, so that the coupling protrusion 135 of the male member 130 is inserted into the coupling groove 115 of the female member 110. can be more easily inserted into

In the embodiment of the present invention, the three cutouts 119 are formed at intervals of 120 degrees with respect to the central axis, but the number and spacing of the cutouts 119 are not limited thereto.

Meanwhile, an inclined surface 118a may be formed on the inner surface of each finger 118 at an angle such that the inner diameter of the coupling groove 115 decreases from the entrance of the coupling groove 115 to the inside.

When the inclined surface 118a is formed in this way, since the diameter of the inlet side is large, the engaging protrusion 135 of the male member 130 can be more easily inserted, and as the engaging protrusion 135 enters, the Since more pressure is applied in an outward direction in contact with the inclined surface 118a, each finger 118 is more easily elastically deformed and can be spread outward.

In addition, the female member 110 includes a locking protrusion 117 formed on the inner end of the inclined surface (118a). The locking protrusion 117 may be a stepped surface formed at a right angle to the central axis at the inner end of the inclined surface 118a.

When the locking protrusion 117 is formed in this way, the inner diameter of the coupling groove 115, which became smaller toward the inside due to the inclined surface 118a, rapidly increases after the locking jaw 117. Therefore, the inner space after the locking protrusion 117 is a space in which the coupling protrusion 135 of the male member 130 is inserted and fixed so as not to fall out.

In addition, when the engaging protrusion 135 passes through the locking protrusion 117 and enters the large space inside, the pressure on the inclined surface 118a is relieved, so that the finger 118 that has spread outward returns to its original position by the elastic force. .

The male member 130 includes a body 131, a coupling protrusion 135 formed at one end of the body 131, and a second flange formed at the other end of the body 131 and having a larger diameter than the body 131 ( 133).

The body 131 of the male member 130 has the same diameter as the body 111 of the female member 110 , and the second flange 133 of the male member 130 has the first flange ( 113) and preferably have the same diameter. However, the present invention is not necessarily limited thereto, and thus may have different diameters if necessary.

On the outer surface of the coupling protrusion 135, an inclined surface 135a having a smaller diameter toward the tip is formed.

When the inclined surface 135a is formed in this way, since the diameter of the tip side is small, it can be more easily inserted into the engaging groove 115 of the female member 110, and as the engaging projection 135 enters, the inclined surface 135a is each Since it naturally contacts the inside of the fingers 118 and applies pressure in the outward direction, each finger 118 can be elastically deformed more easily and spread outward.

In addition, the male member 130 includes a locking protrusion 137 formed at the rear end of the inclined surface 135a of the coupling protrusion 135 . The engaging protrusion 137 serves to prevent the male member 130 from falling out by being caught on the engaging projection 135 of the female member 110 after the engaging projection 135 is inserted into the engaging groove 115 of the female member 110 . do

The engaging projection 137 formed on the coupling protrusion 135 may be a stepped surface formed at a right angle to the central axis at the rear end of the inclined surface 135a.

However, the locking projections 117 of the female member 110 and the locking projections 137 of the male member 130 are not necessarily formed in a vertical plane with respect to each central axis, and the female member 110 and the male member The angle of each of the locking projections 117 and 137 may be appropriately deformed on the premise that the 130 is not separated after being coupled to each other.

In addition, although the body 111 and 131 of the female member 110 and the male member 130 are shown to have a cylindrical shape, the drawings are not limited thereto, and thus may have other shapes such as polygonal poles.

Next, the fixing pin assembly 100a according to the second embodiment of the present invention, as shown in the exploded perspective view of FIG. 5 and the coupling cross-sectional view of FIG. 6 , a female member 110 having a coupling groove 115 and, A male member 130 having a coupling protrusion 135 inserted into the coupling groove 115 of the female member 110, and a pipe 150 surrounding and supporting the female member 110 and the male member 130. include

Since the structures of the female member 110 and the male member 130 are the same as those of the fixing pin assembly 100 according to the first embodiment, a description thereof will be omitted.

The pipe 150 serves to prevent the fingers 118 of the female member 110 from being deformed or damaged by an external load in a state in which the female member 110 and the male member 130 are coupled.

That is, when the body 111,131 of the female member 110 and the male member 130 is supported by surrounding the pipe 150 with the pipe 150, the fingers 118 or the coupling protrusion 135 do not directly receive an external load or impact, so they are deformed. or damage can be prevented.

The pipe 150 is preferably used when combining objects in the form of an empty pipe or channel, and the pipe 150 may be omitted when combining objects in the form of a full inside, such as a bar or a square material. However, since it is not necessarily limited thereto, the pipe 150 may be used irrespective of the shape of the coupling target.

Meanwhile, since the pipe 150 has to surround both the body 111 of the female member 110 and the body 131 of the male member 130, the inner diameter of the pipe 150 is that of the body 111 of the female member 110. It is preferable that the outer diameter is larger than the outer diameter of the body 131 of the male member 130 .

However, since the fingers 118 of the female member 110 have to be slightly elastically deformed outward when the male member 130 is coupled to the female member 110 inside the pipe 150, the inner diameter of the pipe 150 is the finger It is preferable that the diameter of the circumscribed circle in contact with the outer surface of each finger 118 be larger than that of the 118 to enable elastic deformation.

In addition, the pipe 150 is formed between the first flange 113 of the female member 110 and the second flange 133 of the male member 130 after the female member 110 and the male member 130 are coupled to each other. It is preferable to be coupled so as not to fall out. For this, the diameter of the first flange 113 and the diameter of the second flange 133 are preferably larger than the outer diameter of the pipe 150, respectively.

Of course, the material and size of the female member 110 , the male member 130 , and the pipe 150 constituting the fixing pin assemblies 100 and 100a are preferably designed to satisfy the load conditions prescribed by the relevant laws and regulations.
