Description

Lower jockey structure used for system scaffolding}

The present invention relates to an underlying jockey structure used in system scaffolding.

In general, traffic lights for vehicles consist of a main pole fixed to the ground and a crossbeam that is connected to the main pole and extends to the upper side of the road. These crossbeams are equipped with traffic lights so that vehicle drivers can easily identify traffic signals.

In this strut structure for a traffic light, the horizontal bearing capacity of the crossbeam connected to the side of the main strut gradually decreases as it moves away from the part coupled to the main strut, so there is a risk of the crossbeam turning downward due to the load of the crossbeam and the traffic light.

Therefore, in order to prevent the conventional strut structures for traffic lights from bending downward due to load, a wire rope is provided connecting the top of the main strut and the extended end of the crossbeam as shown in FIG. 7 to prevent the crossbeam from bending downward. there is.

However, as these wire ropes are shaken by the wind direction, etc., there is a risk that the crossbeams will shake together, and if the wire ropes are degenerated or damaged and broken due to long-term use, there is a risk that the crossbeams will bend downward.

Furthermore, safety accidents may occur due to crossbeams bent downward, and since the support structure is equipped with multiple wire ropes, it may harm the aesthetics of the road and affect the driver's field of vision and concentration.

Therefore, there is a need to develop a support structure for road traffic lights that can maintain the horizontal fixing force of the crossbeam without wire ropes.

The shock absorbing member 2102 may include a cylindrical body and a circular rod-shaped support portion extending downward from the center of the body and having a narrower diameter than the body. Hereinafter, the shock absorbing member 2102 will be described in a state in which the body and the support portion are formed integrally.

One end (5102a) of the shock absorbing member 2102 may protrude out of the body 2101 through an open end of the body 2101. The protruding end 5102a of the shock absorbing member 2102 may be made of a rubber material capable of absorbing shock. One end 5102a of the shock absorbing member 2102 may have a shape whose diameter narrows upward from the end of the body 2101.

Additionally, the other end of the shock absorbing member 2102 may be formed to have a flat surface. An elastic portion 5103 may be provided to be in close contact with the other end of the shock absorbing member 2102.

The electromagnet unit 2105 can change into an electromagnet when current is supplied.

Through this, the electromagnet unit 2105 can generate a magnetic field, and the generated magnetic field allows the shock absorption member 2102 to move up and down. Here, the amount of current supplied to the electromagnet unit 2105 can be adjusted according to the intensity of shock or vibration of the system scaffold.

For example, when the shock or vibration of the system scaffolding is large, the amount of current supplied to the electromagnet unit 2105 increases, and when the shock or vibration of the system scaffolding is small, the amount of current supplied to the electromagnet unit 2105 becomes small. Through this, the strength of the magnetic field generated by the electromagnet unit 2105 is variable, and the speed and period of the up-and-down reciprocating movement of the shock absorbing member 2102 can be varied by the variable magnetic field.

Meanwhile, the shock absorbing member 2102 can reduce the vertical vibration of the system scaffold through up and down reciprocating movement, but cannot reduce the horizontal vibration of the system scaffold. Horizontal vibration of this system scaffold can be reduced through rotation of the body 2101.

It may be configured to include a vertical support member. Here, the vertical support member of the second support 2107 may be fixed to one surface of the ground. At this time, the body 2101 may have a height spaced apart from the ground by a predetermined distance.

The driving body 2108 may be provided between the second support body 2107) and the rotating body 2106. The driving body 2108 is a pancake-type motor and can rotate the rotating body 2106. Here, the body 2101 rotates in conjunction with the rotation body 2106 by the driving body 2108, and at this time, the rotation of the body 2101 may be a slight movement.

The rotation helper 2109 may be provided between the second support 2107 and the rotating body 2106. The rotation assistance unit 2109 can help the rotating body 2106 rotate smoothly.

Therefore, the shock absorption module 210 according to an embodiment of the present invention can reduce the vertical vibration of the system scaffold through the up and down reciprocating movement of the shock absorbing member 2102, and the system scaffold through the rotational movement of the body 2101. The horizontal vibration of the scaffold can be reduced.

Through the above-described configuration, it is possible to absorb vibrations or shocks caused by construction or disasters transmitted from the system scaffolding, thereby improving the durability of the system scaffolding and base jockey and providing the effect of preventing disruption to construction.

The vertical support 100 according to an embodiment of the present invention may extend to the lower part of the ground and be coupled to the support pillar (P). Here, in order to increase the fixing force of the support pillar (P), a ground-internal part 400 is installed around the bottom of the support pillar (P) inserted into the ground to prevent the support pillar (P) from falling or tilting.
