Description

Prefab Scaffolding System {BUILT-UP SCAFFOLD FOR CONSTRUCTION FIELD}

The present invention relates to a scaffold, and more particularly, to a prefabricated scaffolding system capable of easily assembling and disassembling, particularly rigidly assembled, thereby reducing the risk of collapse and preventing safety accidents.

In general, scaffolds are installed to prevent material, etc. of the construction site from falling to the surrounding buildings, such as people and vehicles passing around the construction site when constructing various buildings.

Scaffolding system according to the prior art is published in Patent Publication No. 10-1224183 (2013.01.22 announcement) "fabricated system scaffolding".

The "fabricated system scaffold" of the Registration Patent Publication No. 10-1224183 (published on January 22, 2013) has a safety scaffold 500 mounted horizontally on the horizontal member 100B as shown in FIG. 1, and the safety scaffold 500 ) is formed with one or more hooks 510 on both sides. The hook 510 has a hook-like shape and is coupled to surround the horizontal member 100B. Therefore, it is configured to be easily installed by placing the safety footrest 500 on the horizontal member 100B through the hook 510 .

However, the safety scaffold 500 according to the prior art has the following problems.

That is, since the safety scaffold 500 is placed on the horizontal member 100B by the hook 510, the safety scaffold 500 flows laterally in the horizontal member 100B, so the operator's posture is unstable while There is a risk of safety accidents.

In addition, since the safety scaffold 500 is configured to be placed on the horizontal member 100B, there is a problem in that the lateral load and the longitudinal load cannot be supported in the entire scaffold on which the safety scaffold 500 is installed.

And the safety scaffold according to the prior art has a problem in that it can fall down while swinging up and down in a strong gust of wind like a typhoon.

Figure 2 is a partially exploded perspective view of a prefabricated scaffolding system according to an embodiment of the present invention, Figure 3 is a bottom perspective view of the scaffold shown in Figure 2.

As shown in the drawings, the prefabricated scaffolding system according to the present invention shown by reference numeral 10 is a vertical support 20, a horizontal support 30, a horizontal support 40, a detachable member, a coupling means and a connector 70. consists of, etc.

The vertical support 20 is installed in a vertical direction from the ground to support an upper load.

And the horizontal support 30 is horizontally connected to each other by a pair of the adjacent vertical support 20 by a connector.

The connector 70 is composed of a connecting piece 71 and a connecting body 75, as shown in FIGS. 4 and 5, the vertical support 20 has a plurality of wedge grooves 73 formed on the connecting piece ( 71) is mounted, and the connecting body 75 is fixedly mounted to both ends of the horizontal support 40 .

A wedge housing 78 is formed in the connecting body 75 , and a wedge 77 is seated in a hollow portion of the wedge housing 78 . The connector 70 may borrow a prior art.

As shown in FIG. 2 , the horizontal support 40 vertically connects the pair of vertical supports 20 to each other.

The horizontal support 40 is also connected to each other with the vertical support 20 by the connector 70 .

And the scaffold 50 is mounted on a pair of the horizontal support 40, and is detachable from the horizontal support 40 by the detachable member.

2 and 3, the scaffold 50 is a scaffold frame 56 and the scaffold frame 56 formed at both ends of the scaffold 50 by bending the scaffold 51 and the metal plate. It is composed of the formed protrusion 53 , and a plurality of perforations 54 are formed in the footrest 51 .

And a flat plate-shaped protrusion plate 59 protruding to the outside is formed on the footrest frame 56 . The protrusion plate 59 is seated on the upper surface of the horizontal support 40 .

The horizontal support 40 will be described with reference to FIGS. 4 and 5 .

The horizontal support 40 includes a horizontal frame 41 formed in the horizontal direction and a pair of longitudinal grooves 43 formed by bending metal plates on both sides of the horizontal frame 41 and the horizontal frame 41 . It is composed of a plurality of long holes 45 formed on the side.

The detachable member includes a longitudinal groove 43 formed on a side surface of the horizontal support 40 and a longitudinal protrusion 53 formed in the longitudinal direction of the scaffold 50 and seated in the longitudinal groove 43 and the length. It is composed of a coupling means for allowing the protrusion 53 to be coupled to the length groove 43 .

Since the longitudinal protrusion 53 is seated in the longitudinal direction in the long groove 43 formed in the longitudinal direction of the horizontal support 40 by the detachable member, the load applied to the footrest 51 is long. Since it is dispersed by the protrusion 53 and the length groove 43, structural stability is increased and durability is increased.

And the coupling means is composed of a plurality of long holes 45 formed in the horizontal support 40 and a coupling hole 60 formed in the scaffold 50, and the long protrusion (45) adjacent to the long hole (45). 53), a through hole 55 is formed.

The coupler 60 includes a round bar-shaped fixing rod 61 passing through the through hole 55 , a ring-shaped ring 63 formed on the fixing rod 61 , and the through hole 55 . ) and a spring case 67 mounted between the ring 63 and a spring 65 embedded in the spring case 67 (see FIGS. 4 and 5).

And as shown in Figures 6 and 7, the foot plate 51 in which the ring 63 of the coupler 60 is located is formed with a manipulation hole 58, therefore, the user 58), the fixing rod 61 can be retracted using a finger on the ring 63 of the coupling port 60, and when the user removes a finger from the ring 63, the spring case ( The fixing rod 61 moves forward by the spring 65 built in 67 , and passes through the long hole 45 .

And the ring 63 is rotatable from the fixing rod 61 to the upper part about the hinge axis.

As shown in the drawing, since the long hole 45 is a hole elongated in the longitudinal direction of the horizontal frame 41, the tip of the fixing rod 61 passing through the through hole 55 is the long hole ( 45) can be easily penetrated and combined.

Installation and dismantling of the prefabricated scaffolding system 10 according to the present invention is as follows.

First, the vertical support 20 , the horizontal support 30 , and the horizontal support 40 are installed as shown in FIG. 2 while being connected to each other by the connector 70 .

And in order to install the scaffold 50 on the pair of horizontal supports 40 , first, the scaffold 50 is positioned on the upper surface of the pair of horizontal supports 40 .

In this state, the front end of the fixing rod 61 passes through the through hole 55 by the spring 65 and protrudes to the outside, so the length protrusion 53 of the scaffold 50 is It cannot be seated in the length groove 43 of the horizontal support 40 .

At this time, when the user retreats the ring 63 with a finger through the manipulation hole 58 , the protruding fixing rod 61 is retracted, and the length projection 53 is seated in the length groove 43 . will become

In this way, when the length projection 53 is seated in the length groove 43, the user removes the finger mounted on the ring 63, and the fixing rod 61 from which the resistance is removed is the spring 65. As shown in FIG. 6, the footrest 50 is seated on the horizontal support 40 and installed through the long hole 45 while being advanced.

The dismantling of the prefabricated scaffolding system 10 according to the present invention is performed in the reverse order.
