Description

{Folding safety net assembly of gang form}

The present invention relates to a gang-foam falling-prevention network which can be installed on the upper and lower sides of a gang form to prevent a safety accident caused by a fall.

The gang form is usually constituted by a Euroform disposed inside the building, a steel foam forming an upper space portion, and a cage providing a working space in the steel foam.

The gantry is pulled up by a tower crane or hydraulic elevator when the wall surface is cured and the bottom is fixed with a tie bolt to the concrete wall and the upper part of the gantry is left as a space for pouring concrete. The whole is integrated into one gang form.

However, in constructing a building using such a gang form, as the number of floors of a building increases, there is a risk that a worker falls or falls into the ground as a result of a fall of a worker or building materials, A safety net is installed on the outer wall of the building, which is being built, to prevent accidents caused by falling objects.

The following Patent Document 1 shows a safety net having a structure that is easy to install on the outer wall surface of a building.

Although the safety net can be folded according to needs as well as the illustrated structure, various modifications have been made in accordance with the conditions of the site. However, as the number of buildings to be built increases, the distance from the lower safety net becomes farther away, There is concern.

In order to solve such a problem, the following Patent Document 2 discloses a gantry with a fall prevention net on the outside.

As illustrated, the fall prevention network installed on the gang form also has the same folding structure, so that surrounding obstacles can be avoided when the gang form is moved upward due to an increase in the number of floors of the building. However, when the extension member is arranged vertically below the cage, the horizontal support of the protection net is connected to the end of the cage, and the wires are connected to both sides of the protection network, the protection net is folded.

The gauze of the above structure has the advantage that the falling prevention effect is surely displayed because the gauze of the above structure does not have to be installed and removed from the building separately, and is moved like a gauntlet.

However, there is a drawback that the illustrated structure is not easy to connect to the bottom of the gantry. In other words, since the extension member is connected to the gang form by lifting up the end portion through the horizontal support of the protection net, it becomes difficult to assemble with the workforce without the help of the tower crane or the hydraulic lift.

In addition, the illustrated structure has a drawback that since the structure of holding the unfolded state of the protection network by only the wire is applied, a load of an actual falling object is applied, and if the wire is broken, a large falling accident may occur.

In order to solve the above-described drawbacks of the conventional gang-foam drop-prevention network, the present invention has a structure that can be easily assembled in the field and can be easily assembled, and can improve work safety by increasing the supporting force for supporting a falling object The present invention has been made in view of the above problems.

In the drop prevention network of the present invention, the link member is attached and fixed to the lower vertical supporting post of a cage provided in a normal gauge, and the link member is provided with a frame bar A cross pin hole and an open fin hole are provided in the same radius around the fixing pin in the link member and the auxiliary pin is selectively inserted through the pin hole And a clip for fitting a horizontal bar connected in an orthogonal direction is integrally attached and fixed to the upper and lower ends of the frame bar forming the drop prevention frame, So that it can be fastened with a wedge interposed therebetween.

In addition to being supported by a normal rope, the fall prevention frame that is folded or folded out of the cage of the gantry is securely held and maintained by an auxiliary pin selectively inserted through the cross pin hole or the open pin hole Therefore, there is an advantage that the safety of the work can be greatly improved.

In addition, since the horizontal bars disposed orthogonally to the upper and lower ends of the frame bars forming the fall preventing frames can be easily fastened and disassembled with the clips and the wedges, the assembly and disassembly in the field can be simplified and facilitated, There is also an advantage to be improved.

Fig. 3 is a diagram showing an embodiment of a drop prevention network related to the present invention in an open state; Fig.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a view showing a state immediately after the drop prevention network according to the present invention is installed in the gauntlet 2, in which a fall preventing frame 6 is provided outside the cage 4 provided outside the gauntlet 2, And is suspended in the upward direction.

More specifically, the fall preventing frame 6 is connected via the link member 10 at the lower end of the column 8 arranged in the vertical direction so as to form the cage 4.

The link member 10 is fixed to the support post 8 by welding or the like to provide a U-shaped groove and is provided at twice the number of the fall preventing frames 6 necessary for the gang form 2, And has three pin holes 12a, 12b and 12c on the side surface thereof.

In the center pin hole 12a positioned above the three pin holes 12a, 12b and 12c, a fixing pin 16 for whitening the frame bar 14 arranged on both sides of the drop prevention frame 6 And the remaining two pin holes 12b are arranged at a predetermined center angle on the locus of the same radius around the hinge point as the cross pin hole 12b and the open pin hole 12c, In addition, the selected one of them is fixed through the auxiliary pin 18.

That is, as shown in FIG. 2, the three pin holes 12a, 12b, 12c and the two pins 16, 18 are formed in such a manner that the fixing pin 16 penetrates the pin holes 12a, The pin hole 12a and the cross pin hole 12b are arranged in the lower vertical direction of the hinge point so as to be arranged in the locus of the same radius A on the axis of the central pin hole 12a, The fall preventing frame 6 can be folded vertically in parallel to the cage 4 or can be unfolded with an inclination corresponding to the central angle between the cross pin hole 12b and the open fin hole 12c.

On the other hand, the frame bars 14 defining both sides of the drop prevention frame 6 are each provided with a clip 20 integrally at the upper and lower ends thereof. The horizontal bars 22 are inserted into the respective clips 20, (24) is inserted and fastened, so that the drop prevention frame (6) can be configured easily and quickly.
