Description

{BRIDGE RAIL USING BUOYANCY}

The present invention relates to a buoyant bridge rail which is automatically turned on when a river water level rises and is automatically raised when the river water level is at a normal water level. More specifically, the present invention relates to a buoyant bridge railway which is very simple in structure, .

Generally, rivers or bridges are equipped with railings made of column bars and guide rails to prevent falling out of bridges when pedestrians or vehicles are parked.

When the water level in the lower part of the raft rises, the floats of the branches, the fragments of the houses, the car damaged water and the like float down from the upper stream to the lower part of the river. When the float is caught, This damage, of course, caused the water level of the overflowing water to rise, causing a secondary damage.

In order to solve such a problem, Korean Patent Registration No. 10-1028110, entitled Moving Guard, discloses an automatic conduction guardrail as a conventional technique, in which a fixed hinge is formed on the upper side of a concrete structure and a hook hanger is formed on the side of the concrete structure A plurality of support rods having a long hole type hinge hole formed therein for engaging with the fixed hinge formed on the concrete structure are formed, guard rails are fixedly installed between the support rods, weight is added to the lower side of the support rods, A ring coupled to a hook of the concrete structure is formed on the side facing the concrete structure on the side, and an empty buoyant body is provided between each of the weight bars formed on the lower side of the plurality of the support bars.

In this conventional automatic conduction railing, when the water level rises, the buoyant body connected to the support rod moves by buoyancy action, and acts to change the moment value at the position where the weight weight and buoyant body are configured around the fixed hinge, And the guard rail and the guard rail are automatically turned to the center axis about the fixed hinge so as to be smaller than the moment value at the position where the guard rail is formed.

At this time, when the water level rises, water pressure continues to be applied, so that the support rods and the guard rails are maintained in a conductive state.

On the other hand, when the water level is lowered and returned to the normal water level, since the water pressure is removed, the water level can be automatically raised by the weight.

However, in the conventional automatic conduction railing, it is necessary to increase the weight of the weights in order to raise the support rods and the guard rails after changing the moment values of the lower and upper sides around the fixed hinge. Raising the weight of the weights is not a problem, In order to solve this problem, there is a problem that production cost is large.

In addition, when the weight of the weight is increased, the force received by the support rod increases, and a twisting moment is generated in the support bar, thereby causing a problem of breakage of the support bar.

In order to solve such a problem, Korean Patent Registration No. 10-1028110 entitled Moving Guard is known, which comprises a structure, a protection case fixed to the structure and having a receiving groove formed inwardly and having a first groove formed on both sides thereof, A handrail formed on both side surfaces of the protective case and having a second groove formed on the inside of the lower end portion and a guide rail provided between the support pillars, a pressure equalizing plate provided on the lower end of the support provided on the handrail, A hinge portion formed of a hinge shaft and a bearing so as to allow the railing to rotate, and a movable shaft coupled and movable in the first and second grooves formed in the protective case and the support, A buoyant portion formed of a buoyant body inserted into the receiving groove of the case and having an inner space formed as an empty space, and a buoyant portion having one side coupled to the first axis of the protective case, The restored part consists of a spring coupled to the second shaft formed on one side of the lower end of the holding formed.

Accordingly, the buoyancy portion is raised by the rise of the water level and is received by the hydrostatic pressure plate when the parapet is conducted, so that the cost can be reduced by omitting a separate component such as the weight, It is possible to prevent the breakage due to the torsional moment of the torsion bar,

However, the moving guard of this patent registration No. 10-1028110 has a problem that since the construction of the protective case is very complicated and heavy, it is very difficult to manufacture and handle, and thus the length is limited.

In addition, the moving guard of Patent Registration No. 10-1028110 has a problem that restoration is difficult due to the springs connected to the first shaft and the second shaft when the rail passes the railing by 90 degrees or more.
