Description

Scaffolding structure for road guardrail {Road Foothold Support Structure For Guardrail}

The present invention is a road guardrail installed on a road guardrail so that users, including drivers, who want to evacuate due to a car accident or the like, can easily cross the rail when performing maintenance work on the inside/outside of the road, etc. It is about scaffolding structures.

Road safety guardrails are generally composed of supports whose lower ends are buried upright on the ground at appropriate intervals, and rails made of plates or pipes that are horizontally connected between the supports and have a barrier function.

By the way, conventional road safety guardrails have to cross the rails when moving from the inside of the road to the sidewalk or the outside of the road due to unavoidable circumstances such as road structure maintenance or traffic accidents. Since it forms a considerable height, there was a problem that it took a lot of time to go around and come out of a place where road safety guards were not installed. There was a risk of a safety accident, such as hitting the face on the road in a state where the center was lost due to a collision.

In order to overcome this, a method of dividing the guardrail to form a passage, a method of carrying a separate scaffold, and a method of forming a scaffold structure integrally with the guardrail have been proposed.

However, if the guardrail is divided, there is a risk that the safety function that prevents the vehicle from leaving the outside, which is the original function of the guardrail, may be impaired, and the appearance is not beautiful. It is rarely carried by ordinary people except workers, and when the scaffolding structure is integrally formed with the guardrail, the scaffolding is exposed on the road while driving, which can act as a factor that increases the risk of safety accidents.

Accordingly, a technique has been developed to prevent the scaffold from protruding outward from the guardrail while constantly installing the guardrail when not in use. As an example, Utility Model Registration Nos. 0483718 and 0370180 are disclosed.

The utility model registration No. 0483718 is a technology in which the scaffold is provided to be rotated in the vertical direction, rotated downward when in use, and folded upward when not in use. However, in the above technology, the means for supporting the scaffold is only a shaft or a ratchet, and since only a part of the scaffold is connected and supported without a separate support means at the bottom of the scaffold, when a person steps on the scaffold, it is caused by the load. There is a problem that it is easily damaged, and accordingly, a problem that a considerable maintenance cost is consumed may occur.

The Utility Model Registration No. 0370180 is a technology of installing a scaffold using a support shaft and a bracket on a rail of a guardrail. However, since the above technology is a structure mounted on a rail, there is a possibility that the bending of the rail may occur due to the load when the operator steps on the scaffold, and the upper bracket and the lower bracket are simply connected to each other via a support shaft Depending on the condition, the support is weak and the footrest is likely to shake easily, and in this case, there is a problem that a safety accident may occur.

In addition, although the above technology may be easily mounted with a bracket and a support shaft, there is a high possibility of shaking due to difficult coupling. However, in the case of rails, it is not easy to install on the rails as double rails are installed on the front and back of the support, and even if installed, it is unstable and there is a risk of safety accidents when crossing the rails. There is a risk of safety accident as you have to jump down by not doing so.

Registered Utility Model Publication No. 20-0370180 (Announcement date: 2004.12.02) Registered Utility Model Publication No. 20-0483718 (Announcement date: 2017.06.09) Registered Utility Model Publication No. 20-0415278 (Announcement date: 2006.04.25)

The present invention was invented to solve the above problems, and an object of the present invention is to increase the stability by increasing the bearing capacity by installing the scaffolding support in surface contact with the fixing means fixed to the support of the guardrail, and to increase the vertical support In the case of providing a scaffolding support, it is easy to install the scaffold support without being restricted by the number of rails and the shape of the guardrail, thereby providing a scaffolding structure for road guardrails that can improve workability.

The configuration of the present invention for achieving the above object is,

A fixing means 20 fixed to the support 11 of the guardrail 10;

A scaffold support 30 installed on one side of the fixing means 20 and formed with a scaffold guide for guiding the scaffold 40;

Hereinafter, a scaffolding structure for a road guardrail according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in the drawing, the scaffolding structure for road guardrails according to the present invention is a structure for use by users, including workers who are performing road maintenance work or drivers who need to evacuate to the outside of the road due to vehicle accidents, etc., guardrail Fixing means (20) fixed to the support (11) of (10); A scaffold support 30 installed on one side of the fixing means 20 and formed with a scaffold guide for guiding the scaffold 40; a scaffold 40 installed in the scaffold guide and moved inward or outward around a guardrail installed on a roadside; It consists of a configuration that includes.

The fixing means 20 is a configuration provided to install the scaffold 40 supported by the scaffold support 30 to the guardrail, and in the present invention, it is installed on the support 11, not the rail of the guardrail.

This fixing means 20 is provided so that the outer surface is in surface contact with one side of the scaffold support 30 while being fixed to the support 11, so that the operator is attached to the scaffold 40 through stable support of the scaffold support 30. Even if you step on it, the scaffold support will stably support the scaffold without damage.

Moreover, the fixing means 20 has the advantage of being easy to handle as it is not restricted by the standard or shape of the rail as it is installed in combination with the support 11.

The scaffold support 30 has a configuration in which one side is coupled to the outer surface of the fixing means 20 in a supported state, and can be formed in a rectangular frame body or in a form in which a rectangular plate is separately coupled to the upper surface of the rectangular frame body. .

As the scaffold support 30 is provided in a state of being coupled to the fixing means 20 coupled to the support 11, it is located outside the rail 12 of the guardrail 10, as shown in FIG. Even in the state in which one side of the scaffold 40 is withdrawn, the other side of the scaffold is supported by the scaffold support 30, and the worker has one side of the scaffold drawn out to the inside of the road based on the rail and the other side of the scaffold located outside the road. You can step on and go over rails.

In the present invention, the fixing means 20, the scaffolding support 30, and the scaffolding 40 are preferably formed of a metal material, and may be configured using a 'b'-shaped angle at the edge for reinforcement.

The scaffold 40 is formed in a substantially rectangular shape, but the edge forms a frame using a square frame or an 'L'-shaped angle, and the inside of the frame has a mesh of a certain size or a plurality of components. It can be configured by combining the formed perforated plates.

The metal net can be provided in all parts of the frame or only in a specific part. In the accompanying drawing, the scaffold used for the first and second rails has a metal mesh attached to all parts, and in the case of a three-stage rail As the rails are usually installed on the inside and outside of the road, the metal mesh is coupled only to a portion of the scaffold located on the inside of the road.

The scaffold 40 may be provided to be retracted or removed while sliding relative to the scaffold support 40, or may be installed to be rotated horizontally and may be provided to be retracted during use.

For the sliding movement and horizontal rotation of the scaffold 40, a scaffold guide is formed on the upper surface of the scaffold support 40.

In the present invention, when two or more fixing means 20 are coupled to the holding means 11, the scaffolds 40 installed on the scaffold support coupled to each fixing means 20 are provided to be positioned on different vertical lines do.

The reason for this is to form each footrest like a staircase so that the operator can easily and conveniently step over the rail when stepping on the footrest. That is, when the scaffolding is located on the same vertical line, it is inconvenient or difficult to use the scaffolding located on the lower side due to the scaffolding located on the upper side.

Looking at the process of crossing the rail from the inside to the outside of the road using the scaffolding structure for road guardrail of the present invention configured as described above,

As shown in FIG. 3, the scaffold 40 is withdrawn to the inside of the road, and then the withdrawn scaffold is stepped on and crossed over the rail 12. The feet go over the rail and step on the footrest supported by the footrest support located outside the road and go over the rail.

When the scaffold 40 is no longer used, the scaffold may be moved outward to the road as shown in FIG. 4 .

Here, the scaffold support 30 supporting the scaffold 40 is not a specific part, but one side is coupled to the outer surface of one side of the fixing means 20 so that it can stably support the scaffold. do.

On the other hand, as an embodiment, the fixing means 20 is composed of a pair of flanges 21 to surround and fix the holding member 11 on both sides, but the flange 21 is inside when the holding member and the holding member are fixed. It can be used by forming a non-slip member 23 so that slip does not occur from the holding.

The non-slip member 23 is preferably made of a plurality of protrusions or irregularities, but other than that, it is possible to prevent slipping after the flange 21 is coupled and fixed to the support.

The inner side of the flange 21 is formed in an arc shape having the same bending angle as the outer peripheral surface bending angle of the support 11, and a portion of the outer surface is formed flat for coupling with the scaffold support 30, and at both ends The wing pieces 22 are formed to protrude outward and are fastened to each other by bolts and nuts.

Therefore, when the flange 21 is fastened to the post 11 with bolts and nuts, the flange is in close contact with the outer surface of the post 11, so that it can maintain a solid state without shaking, and the post 11 is firmly As it is supported, the scaffold support does not shake at all.

In particular, the flange 21 is formed of a plate body so that the entire inner surface is not in close contact with the outer surface of the prop, but the flange is formed as a cylinder and only the bent inner upper and lower parts are closely supported to the outer surface of the prop. By being in the body, it exhibits a higher bearing capacity than that simply formed of a plate body.

The scaffolding structure of the present invention can be installed regardless of the number of rails of the guardrail. When two or more rails 12 of the guardrail 10 are installed and the height of the guardrail is high, a fixing means (20) is coupled to two or more places, the coupling frame 55 is coupled to the outer surface of each fixing means 20, and coupled to the coupling frame 55, a plurality of vertical supports 50 are installed vertically .

Preferably, a total of four vertical supports 50 are provided and disposed outside the support 11, and when connecting each vertical support 50 to each other, it is sufficient to arrange them to form a rectangular or square shape.

By installing the vertical support 50, there is an advantage in that a plurality of scaffold support 30 can be more easily combined and installed, such as being able to combine the scaffold support 30 at the corresponding position even when there are three rails 12. .

At this time, each vertical support installed on both sides of the vertical support 55 around the support 11 is formed with a support coupling hole 51 positioned on the same horizontal line for coupling of the scaffold support 30. However, a plurality of them are formed at regular intervals so that the coupling position of the scaffold support 30 can be adjusted.

Therefore, when two or more rails are installed, there is an advantage in that the scaffolding can be installed by combining the scaffolding support to be positioned between the respective rails even if the width of the rails is different for each installation location.

When installing the scaffold 40 by combining the scaffold support 30 to the vertical support 55, the coupling frame 55 may be formed in the same shape as the guide rail to be used instead of the guide rail.

In the attached Figure 6, the footrest located at the bottom was formed to be slidably moved by inserting it into the coupling frame.

Here, the upper end of the vertical support 50 is provided so as to protrude higher than the upper end of the support 11, and the auxiliary footrest 60 can be installed so that the edge is coupled to the top of each vertical support 50. . The auxiliary scaffold 60 is intended to be able to step over when crossing two or more rails, and as shown in the accompanying drawings, in the case of a three-stage rail, the rails are installed in front and rear of the support to cover the upper side of the support of the rail It is provided to cover the space between the rails while doing so.

Therefore, it is possible to prevent a worker from accidentally falling into the space between the rails while crossing the rails, and even when the rails are installed in a double manner, the operator can easily and conveniently cross the rails.

In addition, when the vertical support 50 is installed, even if the rails are installed in front and rear of the support, a plurality of scaffolding supports can be coupled to the selected position of the vertical support, so that scaffolding can be installed on the inside and outside of the road, respectively. there is

At this time, when a separate footrest is not installed on the outside of the road, auxiliary stairs 65 are installed so that the worker can step down when stepping on the footboard 40 and crossing the rail 12.

The auxiliary stairway 65 is not a big problem in descending when there are one or two rails, but in the case of a three-level rail with three rails, double rails are installed (installed on both sides of the support), and depending on the height and height It is necessary to install it to prevent the occurrence of safety accidents.

The auxiliary stairs 65 may be of any shape as long as the worker can easily step down the stairs, and for convenience of use, the number of stairs is formed to correspond to the number of rails.

In addition, as shown in FIG. 5, a handle bar 70 may be installed on one side of the fixing means 20 or the scaffold support 30 so that the operator can grab it by hand when going over the rail 12. there is. The reason why the handle bar 70 is installed is that there is a possibility that a safety accident may occur due to a worker losing his/her balance while crossing the rail, so that such a safety accident can be prevented in advance and the rail can be crossed more easily. is to help you

On the other hand, in the present invention, the scaffold 40 is installed to the scaffold support 30 to slide or rotate horizontally by the scaffold guide.

As a first embodiment, the scaffolding guide portion may be composed of guide rails 31 formed on both sides of the upper surface of the scaffolding support 30 in a direction perpendicular to the installation direction of the rails 12 of the guardrail 10. .

Therefore, with both sides of the scaffold 40 inserted into each guide rail 31, it slides in and out of the road.

At this time, it is preferable that holding members 32 are formed on both lower surfaces of the footrest 40 in the longitudinal direction so that it is caught on the guide rail 31 and does not move any longer when the footboard is slid to the inside or outside of the road.

By installing the locking member 32, the scaffold 40 is prevented from being pulled into the guide rail 31 in the maximum drawn-in or withdrawn state, and also prevents the scaffold 40 from completely coming out of the guide rail. You can do it.

Therefore, it is possible to reduce material damage by preventing theft and the like while increasing the convenience of use of the scaffold 40 .

As an example of the engaging member 32, it may be configured as a protrusion protruding from the lower surface of the scaffold.

As shown in FIGS. 9 and 10, the scaffold guide unit of the second embodiment may be configured to guide horizontal rotation of the scaffold 40. As an embodiment, a pivoting shaft 35 for coupling one side of the scaffolding 40 to the scaffolding support 30 so that the scaffolding 40 horizontally rotates at the top of the scaffolding support 30, and the pivoting shaft 35 ) Or is formed at a position spaced apart from the rotational shaft is configured to include a rotation limiting means to limit the free rotation in a state in which the scaffold 40 is rotated and drawn to the inside of the road.

The scaffold 40 can be horizontally rotated by the rotation shaft 35, and the rotation is limited by the rotation limiting means in a state in which the scaffold is horizontally rotated to the inside of the road.

The reason why the rotation limiting means is provided is that when the operator steps on the footrest in a state where the footrest 40 is rotated to the inside of the road, a safety accident such as a worker falling due to the rotation of the footrest may occur. This is to prevent rotation of the scaffold in advance.

As an embodiment of the rotation limiting means, the rotation limiting protrusion 36e formed on the lower surface of the footrest 40 at a distance from the rotation shaft 35 and the rotation when the footrest 40 is rotated toward the inside of the road. A protrusion insertion hole 36a formed on one side of the scaffold support 30 so that the limiting protrusion 36e is inserted, and a housing 36b installed on the lower surface of the scaffold support 30 in which the protrusion insertion hole 36a is formed, The insertion protrusion 36c is inserted into the housing 36b from the bottom of the protrusion insertion hole 36a to open and close the upper space of the protrusion insertion hole 36a, and an elastic force is applied to the insertion protrusion 36c. It consists of a spring (36d) installed inside the case to impart.

Before the footrest is rotated to the inside of the road, the insertion protrusion 36c is elastic upward by the elastic force of the spring 36d and is in a state of closing the upper space of the protrusion insertion hole 36, as shown in FIG. When the footrest is rotated to the inside of the road, the rotation limiting protrusion 36e is moved to the protrusion insertion hole 36a and inserted into the upper space of the protrusion insertion hole, and the rotation limiting protrusion inserted into the protrusion insertion hole moves the insertion protrusion to the lower side. will move in the direction

The rotation limiting protrusion is in a state in which a part is inserted into the protrusion insertion hole while pressing the insertion protrusion downward by the weight of the footrest, and in this state, the moment the operator steps on the upper surface of the footrest, the rotation limiting protrusion by the weight of the operator Is inserted into the protrusion insertion hole while further pushing the insertion protrusion downward, and rotation of the scaffold is blocked as the rotation limiting protrusion is perfectly inserted into the protrusion insertion hole.

When the operator removes the foot from the footrest, the insertion protrusion is moved upward by the elastic force of the spring, pushing up the rotation limiting protrusion to keep only a part of it inserted into the protrusion insertion hole. When the footrest is horizontally rotated in the reverse direction, the rotation limiting protrusion is withdrawn from the protrusion insertion hole and is rotated while being in contact with the upper surface of the footrest support.

On the other hand, an anti-rotation plate 37 may be installed at the edge of the scaffold support 30 to be supported on one side of the scaffold so that it can be rotated only within an angle of approximately 90 degrees during the rotational operation of the scaffold 40.

As described above, according to the present invention, by coupling the scaffold support for supporting the scaffolding to the outer surface of the fixing means fixed to the support of the guardrail in surface contact, it can be used without damage by increasing the bearing capacity of the scaffold support. It is possible to solve the cumbersome and inconvenient problems in installation while preventing the bending of the rail, etc. according to the method of fixing and using, not by fixing or binding to the conventional rail.

In particular, scaffolding can be installed regardless of the number of rails, and when a plurality of scaffolding is to be installed, it is installed while maintaining the distance between each scaffolding, so conventionally, the operator has to arbitrarily determine the position of the scaffolding and install it. and discomfort can be relieved.
