To this end, an inspection stand is provided on the side of the structure where the worker can stand. The operator moves along the moving passage provided in the inspection station to check the appearance of the structure or to take necessary repair measures.

In the case of the conventional inspection stand is always installed in a protruding state on the outer surface of the structure, when the inspection stand is not used, the appearance of the structure is not beautiful because of the protruding inspection stand. In particular, in recent years, in designing and constructing bridges, they are designed to harmonize with the surrounding environment together with the stability of the bridges themselves, and have a sleek and beautiful appearance for not only upper structures but also lower structures such as bridges.

However, even if you design and construct a beautiful bridge considering the beauty, if you install the inspection stand on the side of the pier, the beauty of the pier will be greatly harmed by the unfolding inspection street even when you are not using it. Becomes

In addition, birds such as pigeons are often inhabited under the structures such as bridges, but since the checkers always remain unfolded even when not used, the checkpoints are often contaminated with bird droppings, and thus the aesthetics of the bridges are impaired. Of course, the maintenance work of the operator is disturbed. In addition, the unfolded check stand is corroded due to bird droppings or rainwater, resulting in deterioration of the check stand itself and its deterioration in durability.

The present invention has been proposed to solve such a problem, by installing the inspection stand on the structure when not in use to align the side of the structure, and by using the configuration of the inspection stand so that the operator can easily climb up, The purpose of the present invention is to prevent damage to the aesthetics of the structure due to the always-open check-up and prevent damage to the check-up due to dirt.

The folding check table 100 is configured to be easily folded or unfolded through the following structure.

Figure 2a is an exploded perspective view illustrating a connection state of the fixing member and the scaffold member 20 of the folding check table 100 according to the present invention, Figure 2b is a schematic plan view showing an example of the scaffold member 20.

First, referring to the fixing member 10 of the folding check table 100 with reference to Figure 2a, the folding check table 100 is fixed to the outer surface of the structure, that is, the side wall 2 of the piers in the embodiment shown in the figure The member 10 is provided. In the embodiment shown in the figure, the fixing member 10 is composed of a flange 3 attached to the outer surface of the structure and a web 4 formed perpendicular to the flange 3, the flange 3 being connected to the flange 3. Fixing means such as anchor bolts are coupled so that the fixing member 10 is fixed to the side wall 2 of the piers. The scaffold member 20 is rotatably connected to the hinge portion of the lower end of the web 4, and the scaffold member 20 is excessively rotated and unfolded by limiting the rotation of the scaffold member 20. A stopper 5 can be formed to prevent this. In the embodiment shown in the figure, the stopper 5 is configured to have a shape protruding below the hinge portion of the bottom of the web 4 to support the side bar 21 of the scaffold member 20.

The footrest member 20 according to the embodiment shown in FIG. 2B has a structure in which side bars 21 are provided at both sides of the short side thereof, and a rotating rod 22 is provided at the long side thereof. Inside the side bar 21 and the rotating rod 22 is provided with a footrest 23 to the operator is raised. In the exemplary embodiment illustrated in the drawing, the scaffold member 20 has been described as being composed of three separate members. However, the scaffold member 20 may be formed in a form in which the three members are integrally formed. In particular, the scaffold 23 may be configured in the form of a panel rather than a wire mesh as shown in the figure.

On the other hand, as an example of a specific configuration of the hinge portion that the scaffold member 20 is rotatably connected to the fixing member 10 in the embodiment shown in Figure 2a at one end of the rotating rod 22 of the scaffold member 20 A screw portion is formed, and the rotating rod 22 end portion penetrates the side bar 21 and passes through a through hole at the bottom of the web 4 of the fixing member 10 to engage with the bolt member. However, the configuration of the hinge portion is not limited to the above embodiment.

In the present invention, the hinge member 20 is rotatably connected to the scaffold member 20 and the fixing member 10 so that the scaffold member 20 can be easily deployed. In FIG. 2A, as an example of configuring such an elastic hinge, a configuration in which an elastic spring 6 is provided at a position of a through hole at a lower end of the web 4 of the fixing member 10 is illustrated. However, the configuration of the elastic hinge is not limited to this, it can be freely deformed.

On the other hand, when the length of the scaffold member 20 is long between the fixing member 10 of the both sides may be further provided with an auxiliary support member 40 for rotatably supporting one side of the scaffold member 20. . 3A is a perspective view illustrating an auxiliary support member 40 supporting an auxiliary scaffold member 20, and FIG. 3B is an example of a scaffold member 20 suitable for using the auxiliary support member 40. A schematic plan view is shown to show.

As shown in the figure, the auxiliary support member 40 is fixed to the outer surface of the structure, so as to support the long side of the scaffold member 20 to be rotatable. In the embodiment shown in Figure 3a the auxiliary support member 40 is fixed to the outer surface of the structure by the anchor bolt, etc., through the insertion hole through which the rotating rod 22 forming the long side of the scaffold member 20 is inserted through ( 41) is shown formed. A stopper 42 may be formed at the lower end of the auxiliary support member 40 to limit excessive rotation of the scaffold member 20.

On the other hand, in the case of using the auxiliary support member 40 in this way it is preferable to further include an auxiliary bar 24 in the scaffold member 20. In this case, it is preferable that one end of the auxiliary bar 24 is rotatably coupled with the auxiliary supporting member 40 as shown in FIG. 2A. However, even when the auxiliary support member 40 is not used, an auxiliary bar 24 may be provided to support the footrest 23 of the footrest member 20.

In the present invention, the outer surface of the scaffold member 20 is provided with a handrail member 30 to prevent the fall of the operator to be rotatable by the hinge portion. In particular, as shown in the figure, the handrail member 30 may also be rotatably coupled to the scaffold member 20 by an elastic hinge using the elastic spring (6).

On the other hand, the rotation limiting member 50 is provided between the scaffold member 20 and the handrail member 30 to prevent the handrail member 30 from being excessively rotated. The rotation limiting member 50 is composed of a first bar 50a and a second bar 50b, one end of the first bar 50a is rotatably connected to the scaffold member 20, and the second One end of the bar 50b is connected to the handrail member 30, and the first bar 50a and the second bar 50b are connected to each other by the rotating part 51. As will be described later, when folded without using the test stand 100, the first bar 50a and the second bar 50b are folded around the rotating part 51, but when the check stand 100 is used, The first bar 50a and the second bar 50b are unfolded to limit rotation of the handrail member 30 to prevent the handrail member 30 from being excessively rotated and unfolded.

The member number 70, which is not described in FIG. 2A, is a side handrail member 70, and the member number 60 is a latch 60 for fixing the folded state of the handrail member 30 and the scaffold member 20. The member number 61 is a locking projection 61 to be caught by the locking hole (60).

Next, with reference to Figures 4a to 4c will be described for the folding and unfolding process of the check table 100 according to the present invention. Figure 4a is a shaving showing the check stand 100 in the unfolded state, Figure 4b is a side view showing a folding state of the handrail member 30 in the check stand 100 of Figure 4a, Figure 4c is up to the footrest member 20 Side view showing the folded state.

Unscrew the side railing member 70 from the check stand 100 in the use state shown in FIG. 4A, and rotate the handrail member 30 in the direction of the side wall 2, as shown in FIG. 4B. Fold to overlap with. At this time, the first bar 50a and the second bar 50b of the rotation limiting member 50 are rotated in directions E and D, respectively.

Subsequently, the handrail member 30 and the scaffold member 20 in the folded state are rotated in the direction of arrow C, and then folded as shown in FIG. 4C, and the locking hole 60 is hooked on the locking protrusion 61 to maintain the folded state. Thus, the inspection stand according to the present invention, when not in use, since the handrail member 30 and the scaffold member 20 are folded in order to be arranged in a form that is attached to the side wall 2, that is, the outer surface of the structure, The appearance deterioration of the structure due to the (100) can be prevented, it is possible to prevent the damage to the check table due to dirt.

When the check table 100 is used, the reverse operation may be performed, but the foothold member 20 may be unfolded by releasing the fastening state between the locking hole 60 and the locking protrusion 61. As described above, when the scaffold member 20 is connected to the fixing member 10 by an elastic hinge, the scaffold member 20 is automatically unfolded by the elastic force of the elastic spring 6 provided on the elastic hinge. At this time, since the stopper 5 is formed at the lower end of the fixing member 10, it is limited to the rotation of the scaffold member 20 so that the scaffold member 20 is unfolded horizontally without being unfolded.

Subsequently, the handrail member 30 is unfolded. When one end of the handrail member 30 is connected to the scaffold member 20 by an elastic hinge, the handrail member 30 is also easily spread by the elastic force. At this time, the rotation limiting member 50 is also deployed to prevent the handrail member 30 from being excessively rotated. For the safety of the operator by lifting the side railing member 70 to the upper end of the handrail member 30 to complete the preparation of the use of the check table (100).

As described above, the check table according to the present invention is folded in the side of the structure in a state that is not in use, it is configured so that the operator can easily unfold when used. Therefore, when the platform is not in use, the space occupied by the platform can be minimized.

Since the conventional inspection stand is always open, the appearance has damaged the beauty of the structure such as a bridge, and various contaminants accumulate in the worker's work space, which causes the work to be disturbed. However, since the folding check table according to the present invention can be used only when the check is necessary, it can prevent problems such as impairing the aesthetics and damaging the check table.
